[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a battery box locking mechanism as shown in Figures 1-5 which includes an extrusion stop bar 1. One end of the extrusion stop bar 1 is provided with a telescopic cylinder 2 for driving the extrusion stop bar 1 to move. The outside of the extrusion stop bar 1 is provided with a battery storage box 4 for loading batteries, and further includes:

[0024] A mounting block 7, and the mounting block 7 is arranged inside the battery storage box 4;

[0025] A guiding mechanism 6, and the guiding mechanism 6 is used for guiding the installation of the battery storage box 4. The guiding mechanism 6 includes a guide rod 61, the guide rod 61 is inserted through the mounting block 7, and a limiting component for restricting the shaking between the guide rod 61 and the mounting block 7 is arranged inside the guide rod 61.

[0026] Specifically, one end of the extrusion stop bar 1 is fixedly connected to the output end of the telescopic cylinder 2. One end of the telescopic cylinder 2 is fixedly connected with a fixed block 3 for mounting the telescopic cylinder 2. A through hole is opened on one side of the fixed block 3, and the extrusion stop bar 1 is slidably inserted through the through hole. The outer wall of the battery storage box 4 is fixedly connected with a pressing block 5 for mutually pressing with the extrusion stop bar 1.

[0027] Furthermore, the telescopic cylinder 2 is an existing electric control cylinder. The output end of the telescopic cylinder 2 is fixedly welded to the extrusion lever 1. Thus, with the expansion and contraction of the output end of the telescopic cylinder 2, the extrusion lever 1 can be driven to move synchronously. When the output end of the telescopic cylinder 2 contracts, the extrusion lever 1 will be driven to be received into the insertion hole of the fixed block 3, so as not to affect the installation of the battery storage box 4. When the bottom end of the battery storage box 4 is in contact with the top end of the box body bottom support 8, the output end of the telescopic cylinder 2 drives the extrusion lever 1 to extend out of the insertion hole again. At this time, the bottom end of the extrusion lever 1 is in contact with the top end of the pressing block 5, restricting the vertical movement of the battery storage box 4. The extrusion lever 1, the telescopic cylinder 2, the fixed block 3, the battery storage box 4, the pressing block 5 and the box body bottom support 8 form the installation locking mechanism of the vehicle-mounted bottom support and the battery box of the existing electric heavy truck.

[0028] Specifically, one end of the mounting block 7 is fixedly connected to the inner wall of the bottom of the battery storage box 4. A guide groove for inserting the guide rod 61 is provided at the top end of the mounting block 7. The limiting assembly includes a steel ball 66. A locking member for restricting the movement of the steel ball 66 is arranged inside the guide rod 61. A cavity for installing the locking member is provided at the bottom end of the guide rod 61. A clamping groove for the steel ball 66 to be clamped is provided on the inner wall of the guide groove. An insertion hole for inserting the steel ball 66 is provided on one side of the inner wall of the cavity. The locking member includes a limiting rod 65. A receiving groove for receiving the steel ball 66 is provided on the outer wall of the limiting rod 65. A moving rod 64 for moving the limiting rod 65 is fixedly connected to the bottom end of the limiting rod 65. A retaining ring 62 for restricting the moving range of the limiting rod 65 is fixedly connected to the inner wall of the cavity. The moving rod 64 is sleeved inside the retaining ring 62. A moving rod 64 for manual pressing is fixedly connected to the bottom end of the moving rod 64. A compression spring 67 for pushing the button 63 is sleeved on the outer wall of the moving rod 64.

[0029] Further, the contact part between the mounting block 7 and the battery storage box 4 is fixed by welding. A fixing plate is welded to the outer wall of the guide rod 61, and the fixing plate is fixedly connected to the mounting plate 9 by bolts. Thus, when installing the battery storage box 4, the battery storage box 4 can be installed and positioned by inserting the guide rod 61 into the guide groove of the mounting block 7. At the same time, the guide rod 61 can limit the large-scale displacement of the battery storage box 4 in the horizontal direction. This technology is the installation guiding mechanism of the vehicle-mounted bottom support and the battery box of the existing electric heavy truck. The volume of the card slot of the guide groove is one-fourth of the volume of the steel ball 66, and the volume of the storage groove is one-fourth of the volume of the steel ball 66. Three card slots are arranged at equal intervals in a ring shape, and the three guide grooves are on the same horizontal plane. The storage grooves are vertically and respectively corresponding to the card slots, the number and position of the jacks are corresponding to the card slots, the number of the steel balls 66 is corresponding to the number of the jacks, and the aperture of the jack can only expose one-fourth of the volume of the steel ball 66. By extruding the three steel balls 66 on the outer wall of the limiting rod 65, the steel balls 66 extend out of the guide rod 61 through the jacks and are inserted into the card slots, so that the steel balls 66 form extrusion with the card slots, thereby limiting the horizontal movement of the mounting block 7 and preventing the guide rod 61 and the mounting block 7 from shaking. The diameter of the limiting rod 65 is 1.2 times the inner diameter of the retaining ring 62, the diameter of the moving rod 64 is 0.9 times the inner diameter of the inner ring of the retaining ring 62, the diameter of the connection part between the button 63 and the moving rod 64 is 1.1 times the outer diameter of the compression spring 67, and the outer diameter of the compression spring 67 is 0.9 times the outer diameter of the retaining ring 62. The compression spring 67 is always in a compressed state between the retaining ring 62 and the button 63. Therefore, the compression spring 67 will push the button 63 to have a tendency to move away from the retaining ring 62. The button 63 drives the moving rod 64 and drives the limiting rod 65 to move synchronously, so that the limiting rod 65 extrudes the steel balls 66 out of the storage groove, extends out of the jacks and is inserted into the card slots. When it is necessary to disassemble the battery storage box 4, by pressing the button 63 in the direction close to the retaining ring 62, when the storage groove of the limiting rod 65 moves to the position of the steel ball 66, the mounting block 7 can be pulled in the direction away from the box body bottom support 8 to release the locking of the steel ball 66 on the mounting block 7.

[0030] A vehicle-mounted bottom support, the vehicle-mounted bottom support includes the above-mentioned locking mechanism, the vehicle-mounted bottom support includes a box body bottom support 8, the box body bottom support 8 is arranged at the bottom end of the fixed block 3, and a mounting plate 9 for installing the guide rod 61 is fixedly connected to the inner wall of the box body bottom support 8.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
