[0019] (3) Beneficial effects
[0020] The present invention provides a new energy vehicle battery assembly device. It has the following beneficial effects:
[0021] 1. The present invention arranges structures such as a buffer groove, a bottom connecting plate, a buffer support rod and a buffer side plate. In the vertical direction, the hydraulic rod, the piston rod and the shock-absorbing spring form a spring shock absorber. The shock-absorbing spring absorbs the vibration caused by bumps or impacts, and pushes the transverse sliders at both ends of the buffer support rod to slide in the transverse slider groove, so that the transverse slider drives the transverse slide rod to slide in the transverse slide groove, compressing the transverse compression spring, and kinetic energy is absorbed by the transverse slide rod and the transverse compression spring. In the horizontal direction, the buffer side plates on both sides of the battery installation box drive the slide rod to slide in the slide rod groove, and the buffer side plates and the slide rod spring absorb the horizontal force, which has a buffering effect, reduces vibration, makes the battery pack installation more stable, and prevents the battery pack from being unstable due to vibration during the operation of the car, resulting in power loss. At the same time, it avoids the problem of the battery pack being damaged due to force in a violent collision, which poses a more serious safety hazard.
[0022] 2. The present invention arranges structures such as the bayonet, the buckle and the buckle torsion spring. During the insertion of the battery pack, the buckle contacts the battery pack, and the battery pack can squeeze the buckle to both sides. When the buckle rotates, it exerts force on the buckle torsion spring in the buckle shaft hole. When the battery pack is fully inserted into the battery compartment, the buckle returns to its initial position under the action of the buckle torsion spring, so that the end of the buckle is inserted into the bayonet on both sides of the battery pack, locking the battery pack so that the battery pack will not easily loosen in the battery compartment, further improving the stability of the battery pack.
[0023] 3. The present invention adopts the arrangement of heat conducting plates and heat sinks. The heat conducting plates on both sides of the battery compartment transfer the heat generated by the battery pack during operation to the heat sinks, which dissipate heat through the heat sinks, thereby reducing heat accumulation in the battery mounting box and preventing the battery pack from being in a high temperature environment for a long time, which may shorten the battery life and increase the risk of battery spontaneous combustion.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Example 1:
[0035] like Figure 1-6As shown, an embodiment of the present invention provides a new energy vehicle battery assembly device, including an assembly device body 1. In order to solve the problem that the battery pack 202 is unstable in connection due to vibration, resulting in power loss, or the battery pack 202 is damaged by force in a violent collision, forming a more serious safety hazard, the assembly device body 1 is provided with a fixing component 2, a heat dissipation component 3 and a buffer component 4. The buffer component 4 includes a bottom connecting plate 407 and a sliding rod 419. Buffer grooves 401 are opened on both sides of the battery mounting box 201, and a top fixing plate 402 is installed on the top of the buffer groove 401. A hydraulic rod 403 and a shock-absorbing spring 406 are installed in the buffer groove 401. A piston rod 404 is slidably installed in the hydraulic rod 403, and a piston rod 404 is installed on the piston rod 404. A piston 405 is installed, a bottom connecting plate 407 is installed on the piston 405, one end of the shock-absorbing spring 406 is installed on the top fixed plate 402, and the other end of the shock-absorbing spring 406 is installed on the piston 405. The piston 405 is slidably installed in the buffer groove 401. The bottom of the battery mounting box 201 and the top of the bottom connecting plate 407 are both provided with a buffer rod groove 408, and a buffer support rod 409 is rotatably installed in the buffer rod groove 408. A transverse slider groove 415 is provided at the bottom of the battery mounting box 201, and a transverse slider 410 and a transverse compression rod 411 are installed in the transverse slider groove 415. The transverse slider 410 is installed on the buffer support rod 409, and a transverse slide groove 412 is provided in the transverse compression rod 411. A transverse slide rod is slidably installed in the transverse slide groove 412. 413 and a transverse compression spring 414, one end of the transverse compression spring 414 is mounted on the inner wall of the transverse slide groove 412, and the other end of the transverse compression spring 414 is mounted on the transverse slide bar 413. Buffer columns 416 are installed on both sides of the battery mounting box 201, and a slide bar groove 417 is provided in the buffer column 416. A slide bar 419 is slidably installed in the slide bar groove 417, and a buffer side plate 420 is installed on the other end of the slide bar 419. A slide bar spring 418 is slidably installed in the slide bar groove 417. One end of the slide bar spring 418 is mounted on the inner wall of the slide bar groove 417, and the other end of the slide bar spring 418 is mounted on the slide bar 419. When the new energy vehicle is running, when a bump or collision occurs, in the vertical direction, the battery mounting box 201 is opened on both sides. In the buffer groove 401, the hydraulic rod 403, the piston rod 404 and the shock-absorbing spring 406 form a spring shock absorber. The shock-absorbing spring 406 absorbs the vibration caused by bumps or impacts, so that the piston 405 slides up and down in the buffer groove 401, driving the bottom connecting plate 407 to move up and down relative to the battery installation box 201. When the bottom connecting plate 407 approaches the battery installation box 201, the buffer support rod 409 on the battery installation box 201 and the bottom connecting plate 407 rotates, pushing the transverse sliders 410 at both ends of the buffer support rod 409 to slide in the transverse slider groove 415, so that the transverse slider 410 drives the transverse slide rod 413 to slide in the transverse slide groove 412. When the transverse slide rod 413 moves, it compresses the transverse compression spring 414 in the transverse slide groove 412.The lateral slide bar 413 and lateral compression spring 414 absorb kinetic energy. In the horizontal direction, the buffer side plates 420 on both sides of the battery mounting box 201 drive the slide bar 419 to slide within the slide bar groove 417. During the movement of the slide bar groove 417, the slide bar spring 418 within the slide bar groove 417 is compressed. The buffer side plates 420 and the slide bar spring 418 absorb horizontal force, providing a buffering effect and reducing vibration, making the battery pack 202 more securely installed and preventing the battery pack 202 from becoming unstable due to vibration during vehicle operation.
[0036] Example 2:
[0037] like Figure 3 、 Figure 4 and Figure 6 As shown, the embodiment of the present invention provides a new energy vehicle battery assembly device, which is further expanded based on the content of the specific embodiment 1:
[0038] Among them, the fixing component 2 includes a battery mounting box 201 and a battery pack 202, a battery compartment 203 is provided in the battery mounting box 201, the battery pack 202 is installed in the battery compartment 203, and bayonet holes 204 are provided on both sides of the battery pack 202. A buckle 205 is rotatably installed on the top of the battery mounting box 201, and the bayonet hole 204 is adapted to the buckle 205. A buckle shaft hole 206 is provided on the buckle 205, and a buckle shaft 207 and a buckle torsion spring 208 are installed in the buckle shaft hole 206. The buckle shaft 207 is installed on the battery mounting box 201, and one end of the buckle torsion spring 208 is installed on the inner wall of the buckle shaft hole 206, and the other end of the buckle torsion spring 208 is installed on the buckle shaft 207. When assembling the battery of the new energy vehicle, the battery pack 202 is vertically mounted. The battery pack 202 is placed in the battery compartment 203 of the battery installation box 201. During the insertion process of the battery pack 202, the buckle 205 contacts the battery pack 202. Since the contact part of the buckle 205 and the battery pack 202 is an inclined surface, the battery pack 202 can squeeze the buckle 205 to both sides, causing the buckle 205 to rotate around the buckle shaft 207 as the axis. When the buckle 205 rotates, it will apply force to the buckle torsion spring 208 in the buckle shaft hole 206. When the battery pack 202 is fully inserted into the battery compartment 203, the buckle 205 returns to its initial position under the action of the buckle torsion spring 208, so that the end of the buckle 205 is inserted into the bayonet 204 on both sides of the battery pack 202, locking the battery pack 202 so that the battery pack 202 will not easily loosen in the battery compartment 203.
[0039] Example 3:
[0040] like Figure 1 and Figure 3 As shown, the embodiment of the present invention provides a new energy vehicle battery assembly device, which is further expanded based on the content of the specific embodiment 1:
[0041] Among them, the heat dissipation component 3 includes a heat conducting plate 301 and a heat sink 302. The heat conducting plate 301 is installed on both sides of the battery compartment 203. The heat sink 302 is installed between the two heat conducting plates 301. The heat dissipation component 3 is arranged between the battery compartment 203 and the battery compartment 203 in the battery installation box 201. The heat generated by the battery pack 202 during operation is transferred to the heat sink 302 through the heat conducting plate 301. The heat is dissipated through the heat sink 302, thereby reducing the heat accumulation in the battery installation box 201 and preventing the battery pack 202 from being in a high temperature environment for a long time, resulting in problems such as shortening the service life of the battery pack 202 and increasing the risk of spontaneous combustion of the battery pack 202.
[0042] Working principle: When assembling the battery of a new energy vehicle, the battery pack 202 is placed vertically into the battery compartment 203 of the battery installation box 201. During the insertion of the battery pack 202, the buckle 205 contacts the battery pack 202. Since the contact portion between the buckle 205 and the battery pack 202 is an inclined surface, the battery pack 202 can squeeze the buckle 205 to both sides, causing the buckle 205 to rotate around the buckle shaft 207. When the buckle 205 rotates, it applies force to the buckle torsion spring 208 in the buckle shaft hole 206. When the battery pack 202 is fully inserted into the battery compartment 203, the buckle 205 returns to its initial position under the action of the buckle torsion spring 208, so that the end of the buckle 205 is inserted into the battery compartment 203. The battery pack 202 is inserted into the bayonet 204 on both sides of the battery pack 202 to lock the battery pack 202 so that the battery pack 202 will not be easily loosened in the battery compartment 203. The heat dissipation component 3 is arranged between the battery compartment 203 and the battery compartment 203 in the battery mounting box 201. The heat generated by the battery pack 202 during operation is conducted to the heat sink 302 through the heat conducting plate 301. The heat is dissipated through the heat sink 302 to prevent the battery pack 202 from being in a high temperature environment for a long time, which shortens the service life and increases the risk of spontaneous combustion. When the new energy vehicle is running, bumps or collisions occur in the vertical direction. In the buffer grooves 401 on both sides of the battery mounting box 201, the hydraulic rod 403, the piston rod 404 and the reduction The shock spring 406 forms a spring shock absorber, which absorbs the vibration caused by bumps or impacts, so that the piston 405 slides up and down in the buffer groove 401, driving the bottom connecting plate 407 to move up and down relative to the battery installation box 201. When the bottom connecting plate 407 approaches the battery installation box 201, the buffer support rod 409 on the battery installation box 201 and the bottom connecting plate 407 rotates, pushing the transverse sliders 410 at both ends of the buffer support rod 409 to slide in the transverse slider groove 415, so that the transverse slider 410 drives the transverse slider 413 to slide in the transverse slide groove 412. When the transverse slide rod 413 moves, it compresses the transverse compression spring 414 in the transverse slide groove 412, and the transverse compression spring 414 is compressed by the transverse slide 413 and the transverse compression spring 414 absorb kinetic energy. In the horizontal direction, the buffer side plates 420 on both sides of the battery mounting box 201 drive the slide bar 419 to slide in the slide bar groove 417. During the movement of the slide bar groove 417, the slide bar spring 418 in the slide bar groove 417 is compressed. The buffer side plates 420 and the slide bar spring 418 absorb the horizontal force, which has a buffering effect, reduces vibration, and makes the battery pack 202 more securely installed. It prevents the battery pack 202 from being unstable due to vibration during the operation of the car, resulting in loss of car power. At the same time, it avoids the battery pack 202 from being damaged by force in a violent collision, which poses a more serious safety hazard.
[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
