[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides an auxiliary positioning device for fixing the trunk of an electric vehicle, including a support frame 1, a trunk 2 and a support plate 3. The outer surface of the support plate 3 is fixedly connected to the upper end of the support frame 1, the lower surface of the trunk 2 is in contact with the upper surface of the support plate 3, and a positioning mechanism 4 is provided on the outer surface of the trunk 2.

[0028] The positioning mechanism 4 includes a clamping plate 41, a transmission block 42, and a drive assembly 43. There are two clamping plates 41, and the opposite side of the two clamping plates 41 is in contact with the outer surface of the trunk 2. There are two transmission blocks 42, and the upper surface of the two transmission blocks 42 is fixedly connected to the lower surface of the clamping plate 41. The drive assembly 43 is disposed on the inner wall of the transmission block 42.

[0029] The drive assembly 43 includes a positive and negative threaded rod 431 and a drive disk 432. The outer surface of the positive and negative threaded rod 431 is rotatably connected to the inner wall of the transmission block 42 by a thread. The outer surface of the positive and negative threaded rod 431 is rotatably connected to the inner wall of the support plate 3 by a bearing. The rear surface of the drive disk 432 is fixedly connected to the front end face of the positive and negative threaded rod 431.

[0030] The upper surface of the support plate 3 is provided with a first groove 5. There are two first grooves 5, and the inner walls of the two first grooves 5 are slidably connected to the outer surface of the transmission block 42.

[0031] Specifically, by manually rotating the drive disc 432, the rotational motion is converted into linear motion through mechanical transmission thread engagement, so that the clamping plate 41 moves synchronously to fit the trunk 2, thereby achieving lateral fixation and preventing the trunk 2 from sliding or shifting during transportation, thus improving stability and safety.

[0032] Furthermore, the trunk 2 is placed on the upper surface of the support plate 3, and then the drive disk 432 is rotated. The drive disk 432 can drive the positive and negative threaded rod 431 to rotate. The positive and negative threaded rod 431 drives the transmission block 42 to move along the inner wall of the first slide groove 5 through the thread. The transmission block 42 then drives the clamping plate 41 to move closer to the trunk 2 until the clamping plate 41 and the trunk 2 are in contact with each other, thus completing the lateral limiting of the trunk 2.

[0033] Example 2

[0034] The second embodiment of this utility model provides an auxiliary positioning device for fixing the trunk of an electric vehicle. A clamping component 6 is provided on the right surface of the clamping plate 41. The clamping component 6 includes a fixing plate 61, a second sliding groove 62, a first through groove 63, and clamping blocks 64. Two fixing plates 61 are provided, and the left surfaces of the two fixing plates 61 are fixedly connected to the right surface of the clamping plate 41. The second sliding groove 62 is opened on the surface of the front fixing plate 61, and the first through groove 63 is opened on the surface of the rear fixing plate 61. Two clamping blocks 64 are provided, and the outer surfaces of the two clamping blocks 64 are slidably connected to the inner wall of the second sliding groove 62. The outer surfaces of the clamping blocks 64 are in contact with the inner wall of the first through groove 63 and the rear surface of the rear fixing plate 61.

[0035] A spring 7 is provided between the clamping blocks 64, and the upper and lower ends of the spring 7 are fixedly connected to the opposite side of the clamping blocks 64.

[0036] Specifically, this design forms a self-locking mechanism that can automatically lock without additional operation, effectively preventing the clamping plate 41 from loosening due to vibration or external force, and improving the reliability of the fixation.

[0037] Furthermore, when the clamping plate 41 moves toward the trunk 2, the clamping plate 41 can drive the clamping assembly 6 on the right surface, so that the clamping block 64 is squeezed by the rear fixing plate 61. The clamping block 64 moves along the inner wall of the second slide groove 62 to the opposite side. The clamping block 64 can squeeze the spring 7, so that the spring 7 generates elastic force until the distance between the clamping blocks 64 is less than the length between the first through grooves 63, so that the clamping block 64 can pass through the first through groove 63. At this time, the spring 7 releases its elastic force and pushes the clamping block 64 to move to the opposite side until the outer surface of the clamping block 64 is tightly attached to the first through groove 63 and the rear fixing plate 61.

[0038] Example 3

[0039] The third embodiment of this utility model provides an auxiliary positioning device for fixing the trunk of an electric vehicle. A limiting component 8 is provided on the lower surface of the clamping plate 41. There are two limiting components 8, each including a second through groove 81, a limiting groove 82, and a limiting plate 83. The second through groove 81 is opened on the upper surface of the support plate 3, the limiting groove 82 is opened on the surface of the trunk 2, the outer surface of the limiting plate 83 is in contact with the limiting groove 82, and the upper surface of the limiting plate 83 is fixedly connected to the lower surface of the clamping plate 41.

[0040] The upper surface of the support plate 3 is provided with a third sliding groove 9. There are two third sliding grooves 9, and the two third sliding grooves 9 are slidably connected to the limiting plate 83.

[0041] Specifically, the design of the limiting component 8 enables longitudinal movement of the trunk 2, preventing the trunk 2 from moving longitudinally due to bumps and improving the stability of the trunk 2.

[0042] Furthermore, when the clamping plate 41 moves to the opposite side, the lower surface of the clamping plate 41 can drive the limiting plate 83 to slide along the inner wall of the third sliding groove 9 until the limiting plate 83 enters the limiting groove 82.

[0043] Working principle:

[0044] The trunk 2 is placed on the upper surface of the support plate 3, so that the lower surface of the trunk 2 passes through the second through groove 81. Then, the drive disc 432 is rotated, which drives the positive and negative threaded rod 431 to rotate. The positive and negative threaded rod 431 drives the transmission block 42 to move along the inner wall of the first sliding groove 5 through the thread. The transmission block 42 then drives the clamping plate 41 to move closer to the trunk 2 until the clamping plate 41 and the trunk 2 are in contact, thus completing the lateral limitation of the trunk 2. At the same time, the clamping plate 41 can drive the clamping assembly 6 on the right surface and the limiting plate 83 on the lower surface, so that the clamping block 64 is subjected to the rear fixing plate 61. The clamping block 64 moves along the inner wall of the second slide groove 62 to the opposite side, and the clamping block 64 can squeeze the spring 7, so that the spring 7 generates elastic force until the distance between the clamping blocks 64 is less than the length between the first through grooves 63, so that the clamping block 64 can pass through the first through groove 63. At this time, the spring 7 releases its elastic force and pushes the clamping block 64 to the opposite side until the outer surface of the clamping block 64 is tightly attached to the first through groove 63 and the rear fixing plate 61, while the limiting plate 83 slides along the inner wall of the third slide groove 9 until the limiting plate 83 enters the limiting groove 82, thus completing the longitudinal limiting of the trunk 2.

[0045] When it is not necessary to limit and fix the trunk 2, by pressing the clamping block 64 to the opposite side and rotating the drive disc 432 in the opposite direction, the clamping plate 41 can be prevented from sticking to the trunk 2, and the trunk 2 can be removed.

[0046] In summary, the combination of positioning mechanism 4, first slide 5, clamping component 6, spring 7, limiting component 8 and third slide 9 solves the problem that the installation method of fixing with multiple bolts is cumbersome, requires workers to use professional tools, and if the bolts are accidentally lost, the stability of the trunk after installation will be greatly reduced.
