Detailed implementation manners

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 - 17 , the present invention provides a technical solution: a shock-absorbing device for a new energy vehicle battery, including a battery box 2 for storing a battery body 5, a connecting frame 3 arranged outside the battery box 2, and a shock absorber 4 arranged on the connecting frame 3 for connecting the connecting frame 3 with the chassis 1 of the new energy vehicle. It further includes:

[0044] A protection mechanism 6, which is telescopically arranged inside the battery box 2 and abuts against the side wall of the battery box 2, for protecting the battery body 5;

[0045] A fixing mechanism 7, which is arranged on the lid 22 of the battery box 2 and rotates to clamp and fix the protection mechanism 6 when the lid 22 is fixed to the box body 21.

[0046] It should be noted that during operation, the lid 22 of the battery box 2 is opened, and then the battery body 5 is placed inside the box body 21. After the battery body 5 is assembled and fixed, the protection mechanism 6 is installed inside the battery box 2 and abutted and fixed inside the box body 21, so that the protection mechanism 6 protects the upper end and side walls of the battery body 5. After multiple protection mechanisms 6 are installed, the lid 22 is covered on the upper end of the box body 21. During the installation process of the lid 22, the fixing mechanism 7 on the lid 22 contacts the protection mechanism 6, and the protection mechanism 6 pushes the fixing mechanism 7 to rotate, so that the fixing mechanism 7 is clamped and fixed outside the protection mechanism 6. When the lid 22 is placed on the upper end of the box body 21, the fixing mechanism 7 completes the fixing work of the protection mechanism 6, and then the lid 22 and the box body 21 are fixed by bolts. After the battery box 2 is assembled, the connecting frame 3 outside the battery box 2 is fixed to the chassis 1 at the bottom of the new energy vehicle through the shock absorber 4. During the driving of the vehicle, when the battery body 5 is vibrated or impacted, the protection mechanism 6 abuts between the battery body 5 and the lid 22, which can limit the up and down movement of the battery body 5, buffer and protect the battery body 5, effectively reduce the collision between the battery body 5 and the inner wall of the battery box 2, reduce the risk of damage to the battery body 5, improve the service life and safety of the battery. The fixing mechanism 7 is arranged on the lid 22 of the battery box 2 and can rotate to clamp and fix the protection mechanism 6 when the lid 22 and the box body 21 are fixed, ensuring the stability of the protection mechanism 6 during the use of the battery body 5, avoiding the loosening or displacement of the protection mechanism 6 due to vibration, further enhancing the reliability of the protection of the battery body 5, and improving the safety and stability of the battery system.

[0047] In one embodiment, the protection mechanism 6 includes support rods 61 symmetrically arranged in the placement cavity 201 inside the battery box 2, a rotating ring 62 sleeved between the two support rods 61, and an abutting member 63 arranged on the side of the support rod 61 away from the rotating ring 62. The abutting member 63 abuts against the inner wall of the box body 21, and a partition 23 for isolating the battery body 5 is arranged on the inner wall of the box body 21.

[0048] With this design, refer to Figures 5 - 8, the support rods 61 are symmetrically arranged in the placement cavity 201 inside the battery box 2 and are in contact with the upper end of the battery body 5 and the inner wall of the box cover 22. When the battery body 5 is vibrated or impacted by an external force, the support rods 61 can evenly disperse the impact force received by the battery body 5, thereby effectively protecting the battery body 5. The symmetric design of the support rods 61 makes the rotating ring 62 move more smoothly when driving the two support rods 61 to move relative to each other. The two support rods 61 can move outward or inward synchronously and evenly, which helps to accurately adjust the position of the abutting member 63, so that the abutting member 63 can accurately abut at a suitable position between the battery body 5 and the inner wall of the box body 21, improving the accuracy of protection. After the abutting member 63 moves into the gap between the battery body 5 and the inner wall of the box body 21, insert the abutting member 63 into the gap, and then move the support rod 61 outward so that the abutting member 63 abuts and is fixed in the inner wall of the box body 21, completing the fixing work of the support rod 61, so that the support rod 61 can be stably fixed above the battery body 5. With the position adjustment setting of the abutting member 63, the staff can flexibly adjust the protruding length of the abutting member 63 according to the actual size and installation requirements of the battery body 5 to adapt to different battery installation environments and protection requirements. The abutting member 63 can be accurately adjusted according to the position and size of the battery body 5 so that it closely fits at the gap between the battery body 5 and the inner wall of the box body 21. This precise protection method can minimize the shaking space of the battery body 5 during vibration and avoid unnecessary friction and collision between the battery and the inner wall of the box body 21, providing more comprehensive and detailed protection for the battery body 5.

[0049] In one embodiment, a threaded section 611 is provided on the side of the support rod 61 connected to the rotating ring 62, and the threaded section 611 is threadedly connected to the rotating ring 62.

[0050] With this design, referring to Figure 11 , the threaded connection has precise transmission characteristics. The thread directions of the two threaded sections 611 are set in opposite directions. When the rotating ring 62 is rotated, it drives the two support rods 61 to move away from each other. This design makes the position adjustment of the abutting member 63 simple and fast. The staff can flexibly adjust the protruding length of the abutting member 63 according to the actual size and installation requirements of the battery body 5 to adapt to different battery installation environments and protection requirements.

[0051] In one embodiment, a positioning rod 66 for positioning the support rod 61 is provided at the upper end of the partition 23, and a guide groove 6101 for the positioning rod 66 to move is provided at the corresponding position of the support rod 61.

[0052] With this design, referring to Figure 16 、and Figure 17, when installing the protection mechanism 6, the positioning rod 66 is inserted into the guiding groove 6101 of the support rod 61, which can provide accurate positioning for the support rod 61. It ensures that the initial position of the support rod 61 in the battery box 2 is accurate, so that when the rotating ring 62 is rotated subsequently to adjust the position of the abutting member 63, accurate adjustment can be made based on the correct initial position, ensuring that the abutting member 63 can accurately abut at a suitable position between the battery body 5 and the inner wall of the box body 21, improving the installation accuracy and protection effect of the protection mechanism 6. The cooperation between the positioning rod 66 and the guiding groove 6101 makes the installation process of the support rod 61 more convenient. The staff only needs to align the guiding groove 6101 of the support rod 61 with the positioning rod 66 and insert it to quickly complete the preliminary positioning of the support rod 61, without the need for complex adjustment and calibration operations, greatly improving the installation efficiency and reducing the installation difficulty.

[0053] In one embodiment, the abutting member 63 includes an abutting plate 631 provided on the support rod 61, a mounting plate 632 provided at the lower end of the abutting plate 631, a protection rod 634 passing through the mounting plate 632, a protection plate 633 provided on the side of the protection rod 634 close to the battery body 5, and a pushing plate 635 provided on the other side of the protection rod 634 and abutting against the inner wall of the box body 21. An elastic member 636 is sleeved on the portion of the protection rod 634 between the mounting plate 632 and the pushing plate 635, and the elastic member 636 is made of a spring or elastic pad with damping.

[0054] With such a design, referring to Figure 14 and Figure 15 , when the abutting member 63 is inserted into the gap between the box body 21 and the battery body 5, the pushing plate 635 abuts against the side wall of the box body 21. When the support rod 61 continuously pushes the abutting plate 631 to move, the pushing plate 635 pushes the protection rod 634 to move towards the side close to the battery body 5, so that the protection plate 633 is fixed to the battery body 5. When the abutting plate 631 abuts and is fixed to the inner wall of the box body 21, the protection plate 633 abuts and is fixed to the side of the battery body 5. When the battery body 5 sways left and right inside the battery box 2, the protection plates 633 on both sides of the battery body 5 will be squeezed, the elastic member 636 is compressed, and part of the vibration energy is absorbed by its elastic deformation, which can effectively reduce the vibration and impact borne by the battery body 5, reduce the damage suffered by the battery due to collision, and improve the service life and safety of the battery.

[0055] In one embodiment, a limiting plate 64 is sleeved on the support rod 61, and the limiting plate 64 abuts against the top of the battery body 5.

[0056] With such a design, referring to Figure 8, the limiting plate 64 abuts against the top of the battery body 5 and the bottom wall of the box cover 22, which can effectively limit the displacement of the battery body 5 in the vertical direction. During the driving of the vehicle, due to uneven road surfaces or operations such as acceleration and deceleration, the battery body 5 will be subjected to an upward force and generate vertical shaking. The existence of the limiting plate 64 can prevent the battery body 5 from moving upward excessively, ensuring that the battery always remains in the correct position within the battery box 2 and avoiding problems such as loose electrical connections and short circuits caused by battery displacement.

[0057] In one embodiment, a wire bundling clip 65 for placing wires is provided on one side of the limiting plate 64.

[0058] With this design, referring to Figure 8 , a plurality of wire bundling clips 65 are evenly distributed on the limiting plate 64. In a new energy vehicle battery system, there are a large number of wires for connecting various components such as batteries, controllers, and sensors. The wire bundling clips 65 can bundle these scattered wires together, making the wire layout more neat and orderly. This is not only aesthetically pleasing but also convenient for identifying and finding specific wires, improving the maintainability of the electrical system.

[0059] In one embodiment, the fixing mechanism 7 includes a mounting frame 71 provided on the box cover 22, a rack 72 penetrating through the mounting frame 71, a mounting shaft 74 provided inside the mounting frame 71, a gear 73 sleeved on the mounting shaft 74, and a clamping plate 75 provided on the gear 73 for clamping the rotating ring 62. The gear 73 is symmetrically arranged with respect to the rack 72 and is meshed with the rack 72. A moving groove 7101 for the rack 72 to move is formed on the mounting frame 71, and rotating grooves 7102 for the clamping plate 75 to rotate are provided on both sides of the mounting frame 71. A through groove 2201 for the rack 72 to move is formed on the box cover 22. The lower end of the rack 72 is arc-shaped and is correspondingly shaped to the rotating ring 62.

[0060] With this design, referring to Figures 8 - 13, when connecting the box cover 22 with the box body 21, the rack 72 first contacts the rotating ring 62. During the continuous downward movement of the box cover 22, under the action of the rotating ring 62, the rack 72 moves upward inside the mounting frame 71. Then, tooth flanks are provided on both sides of the rack 72, and the rack 72 meshes with the gear 73, driving the clamping plate 75 to move inward along the mounting shaft 74 to make a converging movement, so that the clamping plate 75 clamps and fixes the outside of the rotating ring 62. And when the box cover 22 contacts the box body 21, the clamping plate 75 completes the fixing work of the rotating ring 62. Then, the box cover 22 and the box body 21 are fixed by bolts. The clamping and fixing of the clamping plate 75 to the rotating ring 62 can firmly fix the protection mechanism 6 inside the battery box 2, which ensures the stable positions of components such as the support rod 61 and the abutting member 63, enabling them to always play an effective protection role when the battery is vibrated and impacted, and preventing the battery body 5 from colliding with the inner wall of the battery box 2.

[0061] In one embodiment, a limiting block 711 for restricting the moving direction of the rack 72 is arranged inside the moving groove 7101. A limiting groove 7201 for the limiting block 711 to move is formed on the rack 72. An anti-slip block 621 is arranged at the position of the rotating ring 62 corresponding to the clamping plate 75.

[0062] With such a design, referring to Figure 12 and Figure 13 , the cooperation between the limiting block 711 in the moving groove 7101 and the limiting groove 7201 on the rack 72 can accurately restrict the moving direction of the rack 72. During the operation, the rack 72 can only move along the direction of the limiting groove 7201, avoiding the deviation or shaking of the rack 72, ensuring the accurate meshing transmission between the rack 72 and the gear 73, improving the movement stability of the fixing mechanism 7. When the vehicle vibrates during driving, the cooperation between the limiting block 711 and the limiting groove 7201 can prevent the rack 72 from generating unnecessary displacement due to vibration, ensuring that the rack 72 always stays in the correct position, which helps to reduce the influence of vibration on the operation of the fixing mechanism 7, making the clamping of the clamping plate 75 to the rotating ring 62 more stable, and improving the anti-vibration performance of the entire battery box 2 fixing system.

[0063] A battery shock absorption method for a new energy vehicle, which is used for a new energy vehicle battery shock absorption device as described above: includes the following steps;

[0064] S1. Place the battery body 5 in the installation groove in the inner partition 23 of the box body 21 to complete the assembly work of the battery body 5;

[0065] S2. Place the support rod 61 inside the box body 21, align the guide groove 6101 on the support rod 61 with the positioning rod 66 and insert it into the positioning rod 66. Then rotate the rotating ring 62, and the threaded section 611 is threadedly connected to the rotating ring 62, driving the two support rods 61 to move away from each other. When the abutting member 63 moves to the gap between the battery body 5 and the box body 21, lower the abutting member 63 and insert it into the gap, and the limiting plate 64 abuts against the top end of the battery body 5. Then rotate the rotating ring 62 so that the abutting member 63 abuts against and is fixed to the inner wall of the box body 21, completing the assembly work of the protection mechanism 6;

[0066] S3. Cover the box cover 22 on the upper end of the box body 21. During the downward movement of the box cover 22, the lower end of the rack 72 contacts the rotating ring 62. Then, under the restriction of the rotating ring 62, the rack 72 moves upward, driving the gear 73 to rotate, so that the clamping plate 75 rotates along the mounting shaft 74. Then the clamping plate 75 clamps and fixes on the rotating ring 62 to fix the clamping ring 62.
