[0024] 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 in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a power battery box bracket as Figures 1-7 shown, including a box body bracket 1. A battery interface 2 for connecting a battery is provided at the top of the box body bracket 1. A locking pin 3 for locking the battery box is provided at the top end of the box body bracket 1. One end of the locking pin 3 is provided with a cylinder 4 for driving the locking pin 3 to move. One end of the cylinder 4 is provided with a mounting block 5 for mounting the cylinder 4. It further includes:

[0026] A protection mechanism 6, the protection mechanism 6 includes a guide block 61. The guide block 61 is used for guiding the installation of the battery box. The guide block 61 is provided at the top end of the mounting block 5. A connecting member for connecting with the mounting block 5 is provided at the bottom end of the guide block 61. A protection member for protecting the guide block 61 is provided on the outer wall of the guide block 61;

[0027] A locking bolt 7, the locking bolt 7 is used for fixing the connecting member and the mounting block 5. The locking bolt 7 is provided at the bottom of the connecting member.

[0028] Specifically, the bottom end of the mounting block 5 is fixedly connected to the top end of the box body bracket 1. A receiving groove for slidably inserting the locking pin 3 is formed on one side of the mounting block 5 away from the cylinder 4. One end of the locking pin 3 is fixedly connected to the output end of the cylinder 4. One end of the cylinder 4 is fixedly connected to one side of the mounting block 5 close to the cylinder 4.

[0029] Furthermore, the box bracket 1 and the battery interface 2 form the existing battery box bracket of an electric heavy truck. The battery interface 2 is used to connect the connector inside the battery box. The part where the mounting block 5 contacts the box bracket 1 is fixed by welding. Six mounting blocks 5 are provided, which are symmetrically arranged on the inner sides of the box bracket 1 respectively. The vertical directions of the locking pin 3 and the cylinder 4 correspond to the mounting block 5. The cylinder 4 is fixedly connected to the mounting block 5 by bolts. The locking pin 3 is arranged on the side of the mounting block 5 facing the outer wall of the box bracket 1. When the battery box is installed on the box bracket 1, the output end of the cylinder 4 drives the locking pin 3 to be received into the inside of the mounting block 5. Then the battery box is hoisted to the top of the box bracket 1. Then the cylinder 4 extends through the output end again, so that the locking pin 3 extends out of the mounting block 5, and the bottom end of the locking pin 3 presses against the top end of the bottom frame of the battery box to limit the battery box, realizing the fixed installation of the battery box and the box bracket 1.

[0030] Specifically, the connecting piece includes a connecting block 62. A slot for inserting the connecting block 62 is opened at the top end of the mounting block 5. A circular through hole is opened on one side of the connecting block 62. A threaded groove is opened on one side of the mounting block 5. The locking bolt 7 is threadedly inserted into the threaded groove, and the threaded groove penetrates the slot.

[0031] Furthermore, the number of the protection mechanisms 6 corresponds one by one to the vertical direction of the mounting block 5. When the battery box is installed, the inclined surface of the guiding block 61 will touch the inner wall of the bottom of the battery box, so as to play a guiding role in the movement of the battery box, reducing the installation deviation between the battery box and the box bracket 1. On both sides of the bottom end of each guiding block 61, connecting blocks 62 are symmetrically arranged. The part where the guiding block 61 contacts the connecting block 62 is fixed by welding. The size of the slot corresponds to the size of the connecting block 62, and the number of the slots opened corresponds to the size of the connecting block 62. The diameter of the circular through hole is 1.1 times the outer diameter of the screw rod of the locking bolt 7. The thread on the inner wall of the threaded groove meshes with the thread on the outer wall of the locking bolt 7. The slot is opened vertically, and the threaded groove is opened horizontally. The slot and the threaded groove are arranged in a cross shape in the vertical plane. By inserting the locking bolt 7 into the threaded groove and the circular through hole at the same time, the connecting block 62 and the mounting block 5 are locked, realizing the fixed connection between the guiding block 61 and the mounting block 5. When the paint on the outside of the guiding block 61 is damaged and the metal inside the guiding block 61 is rusted, it will not conduct to the mounting block 5 and the box bracket 1, reducing the impact on the overall bracket. At the same time, the locking bolt 7 can be disassembled to replace the guiding block 61 without replacing the mounting block 5, saving materials.

[0032] Specifically, one end of the guiding block 61 away from the cylinder 4 is provided with an inclined surface for guiding the battery box. The protective member includes a protective pad 63. The protective pad 63 is arranged at the top of the inclined surface. A groove is provided at the top of the inclined surface. The bottom end of the inner wall of the groove is fixedly connected with a second magic tape 65. A first magic tape 64 for connecting with the second magic tape 65 is fixedly connected to the side of the protective pad 63 facing the guiding block 61.

[0033] Furthermore, the protective pad 63 is made of rubber material. The part of the first magic tape 64 in contact with the protective pad 63 is fixed by gluing. The part of the second magic tape 65 in contact with the groove is fixed by gluing. The first magic tape 64 and the second magic tape 65 are existing magic tapes. The first magic tape 64 is the sub - surface and the second magic tape 65 is the mother - surface. By pasting the first magic tape 64 and the second magic tape 65, the protective pad 63 can be conveniently fixed on the inclined surface of the guiding block 61. Thus, when the guiding block 61 guides the battery box, it will touch and press the protective pad 63, reducing the damage of the battery box to the guiding block 61, thereby reducing the replacement frequency of the guiding block 61. When the protective pad 63 is damaged, it can be replaced more conveniently by tearing the first magic tape 64.

[0034] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
