The embodiment of the invention provides a displacement detection device, a linear motor, an electromagnetic shock absorber and a vehicle, and the displacement detection device comprises a first part; a second member with respect to which the first member is movable; a holder provided between the first member and the second member; and the position detection piece and the holding piece are at least partially and highly overlapped. Therefore, when the first component and the second component move relatively, the position detection piece and the holding piece at least partially coincide in height, so that the position detection piece and the holding piece can have a relatively large coincident surface in the height direction, and the position detection piece and the holding piece have a relatively good alignment effect; and therefore, the displacement generated by the relative movement between the first component and the second component can be detected more accurately. The problem that displacement detection is inaccurate due to the fact that the relative movement between the grating guide rail and the grating scanning head is easy to deviate when the grating guide rail and the grating scanning head are used for displacement detection is avoided, and the displacement detection accuracy is improved.

    本申请实施例提供了一种位移检测装置、直线电机、电磁减震器及车辆,位移检测装置,包括:第一部件;第二部件,第一部件能够相对于第二部件移动;保持件,保持件设置在第一部件与第二部件之间;位置检测件,位置检测件与保持件至少部分高度重合。这样,在第一部件与第二部件之间相对运动时,由于位置检测件与保持件至少部分在高度上相重合,使得位置检测件与保持件之间在高度方向能够具有较大的重合面,因而使得两者具有较好的对位效果,进而对第一部件与第二部件之间进行相对运动产生的位移具有更高的检测精准度。避免采用光栅导轨和光栅扫描头进行位移检测两者之间的相对运动易产生偏移,避免易造成位移检测不准的问题,提高了位移检测精准度。
