Description

Technical Field

[0001] This utility model relates to the field of battery bracket technology, specifically a shock-absorbing bracket for new energy vehicle batteries. Background Technology

[0002] New energy vehicles are more environmentally friendly because they use renewable energy fuels as power sources. They can also achieve energy conservation and emission reduction by changing the on-board power unit. Most batteries commonly used in new energy vehicles are installed inside the chassis and fixed with brackets to stably deliver electricity to the vehicle.

[0003] The bracket needs to be carefully wrapped around the corners of the battery pack casing to maintain stability while the car is in motion. However, it often lacks shock absorption. If there is a bump, the impact will be directly applied to the battery pack casing, making it difficult to ensure the structural integrity of the battery pack.

[0004] Now, a novel shock-absorbing bracket for new energy vehicle batteries is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing bracket for new energy vehicle batteries to solve the problem of poor shock absorption function mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing bracket for a new energy vehicle battery, comprising a battery body and a front retainer. The front retainer is snapped and fixed at the four corners of the front end of the battery body, and the rear retainer is snapped and fixed at the four corners of the rear end of the battery body. A sliding sleeve is fixed to the outer side of the rear retainer. A sleeve is movably connected to the outer side of the sliding sleeve. A base is fixed to the outer side of the sleeve, and a reinforcing plate is longitudinally fixed between the bases. Assembly holes are respectively provided at the top and bottom of the interior of the base. A limit rod is fixed to the front end of the interior of the sleeve. A spring is fixed between the interior of the sleeve and the sliding sleeve. A silicone sleeve is fixed to the groove of the sleeve.

[0007] As a further technical solution of this utility model, the spring is wound around the outside of the limiting rod, and the sliding sleeve moves back and forth along the surface of the limiting rod.

[0008] As a further technical solution of this utility model, the front and rear retaining sleeves are each provided with a longitudinal insertion hole 1 inside, and a short rod is fixedly inserted between the insertion holes 1. The sides of the front and rear retaining sleeves are each provided with a second insertion hole, and a long rod is fixedly connected between the second insertion holes 2. A limit bolt 1 is threadedly connected between the front and rear retaining sleeves and the short rod. A limit bolt 2 is threadedly connected between the front and rear retaining sleeves and the long rod. The back plates of the front and rear retaining sleeves are each provided with a third insertion hole, and a support rod is fixedly inserted between the third insertion holes 3. A side bolt is threadedly connected between the front and rear retaining sleeves and the support rod.

[0009] As a further technical solution of this utility model, the front card sleeve and the rear card sleeve are of the same size, and the front card sleeve and the rear card sleeve wrap around the octagonal corners of the battery body shell.

[0010] As a further technical solution of this utility model, a sleeve block is movably sleeved on the outside of the short rod, and a fastening bolt is threadedly connected to the side of the sleeve block. A ball is movably embedded in the rear of the sleeve block. A sleeve plate is fixed to the rear of the side of the sleeve block, and a screw hole is provided on the side of the sleeve plate. A reinforcing bolt is threadedly connected to the screw hole. An electrode plate is fixed to the left side of the battery body.

[0011] As a further technical solution of this utility model, the sleeve block moves vertically along the surface of the short rod, and the ball bearing slides against the front surface of the battery body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the shock-absorbing bracket for new energy vehicle batteries not only maintains the stability of the battery structure and facilitates installation and disassembly, but also restricts the connection harness;

[0013] (1) By fixing a base on the outside of the sleeve, after the front and rear sleeves are installed, the sleeve is fixed on the chassis of the vehicle through the base with the assembly hole. During the driving of the car, the sliding sleeve will slide along the surface of the limit rod due to the influence of external vibration and be reinforced by the spring. The sliding sleeve is also embedded in the silicone sleeve at this time, which can increase the friction resistance, thereby protecting the battery body inside the bracket and preventing it from vibrating due to external impact.

[0014] (2) By snapping and fixing the front sleeves at the four corners of the front end of the battery body and the rear sleeves at the four corners of the rear end of the battery body, the four sets of front sleeves and rear sleeves are snapped and fixed at the eight corners of the surface of the battery body. A short rod is inserted into the corresponding insertion hole one, a long rod is inserted between the insertion holes two, and a support rod is inserted between each front sleeve and rear sleeve. Then, the limiting bolt one, the limiting bolt two and the side bolts are locked. This makes it convenient to assemble the bracket in time and also allows for quick disassembly.

[0015] (3) By fixing a sleeve plate behind the side of the sleeve block, under the lubrication of the ball, the sleeve block is pre-moved outside the short rod and locked with the fastening bolt. Adjust the position of the reinforcing bolt connected at the rear. When connecting the wire harness at the electrode plate of the battery body, the wire harness passes through the inside of the sleeve plate. The reinforcing bolt is screwed into the selected screw hole so that the metal wire of the wire harness can be wound, which restricts the battery wire harness and prevents it from sliding or leaving its original position.

A spring 20 is fixed between the inside of the sleeve 22 and the sliding sleeve 19. A silicone sleeve 18 is fixed to the groove of the sleeve 22.

[0023] Spring 20 is wound around the outside of limiting rod 21, and sliding sleeve 19 moves back and forth along the surface of limiting rod 21;

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, after the front sleeve 2 and the rear sleeve 17 are installed, the sleeve 22 is fixed to the chassis of the vehicle through the base 8 with the mounting hole 11. During the driving of the car, affected by external vibration, the sliding sleeve 19 will slide along the surface of the limit rod 21 and be connected and reinforced by the spring 20. At this time, the sliding sleeve 19 is also embedded in the silicone sleeve 18, which can increase the frictional resistance and thus protect the battery body 1 inside the bracket.

[0025] The front sleeve 2 and the rear sleeve 17 each have a longitudinally arranged insertion hole 13 inside, and a short rod 5 is fixedly inserted between the insertion holes 13. The sides of the front sleeve 2 and the rear sleeve 17 each have an insertion hole 24 inside, and a long rod 10 is fixedly connected between the insertion holes 24. A limit bolt 4 is threaded between the front sleeve 2 and the rear sleeve 17 and the short rod 5. A limit bolt 9 is threaded between the front sleeve 2 and the rear sleeve 17 and the long rod 10. The back plates of the front sleeve 2 and the rear sleeve 17 each have an insertion hole 35, and a support rod 27 is fixedly inserted between the insertion holes 35. A side bolt 3 is threaded between the front sleeve 2 and the rear sleeve 17 and the support rod 27. The front sleeve 2 and the rear sleeve 17 are the same size and are wrapped around the octagonal corners of the battery body 1.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, four sets of front retaining sleeves 2 and rear retaining sleeves 17 are respectively snapped and fixed at the eight corners of the surface of the battery body 1. Short rods 5 are inserted into the corresponding insertion holes 13, long rods 10 are inserted between the insertion holes 14, and support rods 27 are inserted between each front retaining sleeve 2 and rear retaining sleeve 17.

Short rods 5 are inserted into the corresponding insertion holes 13, long rods 10 are inserted between the insertion holes 14, and support rods 27 are inserted between each front retaining sleeve 2 and rear retaining sleeve 17. Then, the limiting bolts 1-4, 2-9, and side bolts 3 are tightened. After that, the sleeve 22 is fixed to the chassis of the vehicle through the base 8 with the assembly hole 11. During the driving process of the car, under the influence of external vibration, the sliding sleeve 19 will move along the limit. The surface of the position rod 21 slides and is reinforced by the spring 20. The sliding sleeve 19 is also embedded in the silicone sleeve 18 at this time, which can increase the frictional resistance and thus protect the battery body 1 inside the bracket. Finally, under the lubrication of the ball 26, the sleeve block 7 is pre-moved on the outside of the short rod 5 and locked with the fastening bolt 6. The position of the reinforcing bolt 24 connected at the rear is adjusted. When connecting the wire harness at the electrode plate 16 of the battery body 1, the wire harness passes through the inside of the sleeve plate 23. Then, the reinforcing bolt 24 is screwed into the selected screw hole 25 so that the metal wire of the wire harness is wound and the battery wire harness is restricted.
