Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and more specifically, to an adjustable new energy vehicle battery protection device. Background Art

[0002] There are slight differences with different types of new energy vehicles. In pure electric vehicles equipped with only batteries, the battery is the only power source of the vehicle drive system. The battery can play the role of the main power source of the vehicle drive system, and can also serve as an auxiliary power source. The battery needs to be protected by a protective device when it is installed; However, the existing new energy vehicle battery protection device has the following shortcomings when protecting the battery: after the battery is installed inside the protection device, the upper and lower layers of batteries are stacked together. When the new energy vehicle is moving, the battery is prone to shaking inside the protection device, causing the upper and lower layers of batteries to collide and hindering the heat dissipation of the battery, which not only reduces the protection effect of the battery but also causes the battery to heat up inside the protection device, reducing the efficiency of the battery power supply. Summary of the invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: an adjustable new energy vehicle battery protection device, whose structure includes a base, a protection box, and a top cover. The lower end of the protection box is fixedly installed on the upper surface of the base, and the top cover is installed on the upper end of the protection box. A locking plate is provided on the edge of the base to fix the base to the chassis of the car. A connecting mechanism is provided inside the corner of the protection box, and a partition is installed inside the protection box. The lower end of the fixing column provided on the connecting mechanism is fixed inside the corner of the protection box, and the upper end of the fixing column is embedded and installed on the connecting mechanism. Inside the external tube of the mechanism, a spring is installed between the fixed column and the external tube, a limiting ring is fixedly installed at the lower end of the external tube, and a sleeve ring is slidably installed on the outside of the external tube, the sleeve ring is in contact with the upper surface of the limiting ring, an inner plate is welded on the outer surface of the sleeve ring, and the inner plate is welded to the corner end of the partition, four sleeve rings and four inner plates are each provided, and are distributed at the four corners of the partition, and the four sleeve rings are used to adjust and slide on the four external tubes inside the four corners of the protective box, so that the partition as a whole can be placed horizontally and stably in the middle position inside the protective box.

[0004] As a further improvement of the present invention, a plurality of height-increasing pads are installed on the upper surface of the partition to raise the bottom of the battery, and four partitions are equidistantly arranged inside the partition to independently support the four batteries. A groove bar runs through the inside of each partition to dissipate the heat generated by the battery. Card rods are provided at both ends of the partition, and the card rods are plugged into the plug-in slots provided on both sides of the protective box. The card rods are made of metal and have a certain elasticity, and the upper end of the card rod is a bent structure, which is plugged into the plug-in slots on both sides of the protective box through the card rods on both sides.

[0005] As a further improvement of the present invention, a bearing base plate is movably installed at the bottom of the inner side of the protection box, and a telescopic hose is also arranged at the bottom of the bearing base plate. A spring telescopic rod is connected to the outside of the telescopic hose, and an air guide nozzle is arranged at the bottom of the telescopic hose, which is connected to the heat collecting plate at the bottom of the base. Twelve grooves are passed through the inside of the bearing base plate, and three are in a group. The four batteries in the lower layer are supported by the bearing base plate, and the heat generated by the batteries is dissipated through the grooves. At the same time, when the protection box vibrates, the batteries squeeze the bearing base plate. At this time, the telescopic hose and the spring telescopic rod at the bottom of the bearing base plate perform elastic buffering to reduce the vibration of the batteries.

[0006] As a further improvement of the present invention, a contact plate is installed inside the protection box, and a transverse linkage plate is connected to the back axis of the contact plate. A sliding block is connected to the other end axis of the transverse linkage plate, and the sliding block is slidably installed on the outside of a spring guide rod arranged inside the protection box. Two sliding blocks and two transverse linkage plates are each provided, and are distributed on the left and right. When the contact plate contacts the surface of the battery and is subjected to pressure, the two transverse linkage plates are linked in opposite directions, so that the two sliding blocks slide in opposite directions on the spring guide rod.

[0007] As a further improvement of the present invention, a limit plate is slidably installed inside the protection box, and a limit strip is welded on the top of the limit plate, and the limit strip limits the upward and downward sliding of the limit plate.

[0008] As a further improvement of the present invention, a flat head screw is passed through the inside of the top cover, and the lower end of the flat head screw is locked in the threaded tube arranged on the top of the external tube. A plug-in rod is welded on the lower end surface of the top cover, and the lower end of the plug-in rod is plugged into the plug-in tube installed on the upper surface of the base. The plug-in rod and the plug-in tube are both attached to the outer surface of the protective box. There are four flat head screws and they are distributed at the four corners of the top cover. While being locked in the four threaded tubes by four flat head screws, multiple plug-in rods are respectively plugged into the corresponding multiple plug-in tubes.

[0009] As a further improvement of the present invention, a lower pressing plate is further installed at the middle end of the bottom of the top cover. A pressing rod is axially connected to the upper surface of the lower pressing plate. The upper end of the pressing rod is connected to a spring tube sleeve. Four pressing rods are provided, and two spring tube sleeves are provided. Two pressing rods and one spring tube sleeve form a group, which are respectively arranged between the middle end of the bottom of the top cover and the left and right sides of the upper end of the lower pressing plate. The two pressing rods in each group respectively pass through the head and tail ends of the spring tube sleeve by clearance fit.

[0010] The beneficial effects of the present invention are as follows: 1. The bottom of the upper-layer battery is supported by the partition plate. The batteries on the upper and lower sides inside the protection box are separated and placed by the partition plate. At the same time, elastic support is carried out through the spring installed between the fixed column and the outer connecting pipe to damp the socket ring, thereby damping the whole partition plate to avoid collision when the batteries are stacked. 2. When the protection box vibrates during movement, the battery presses the bearing bottom plate. At this time, the telescopic hose and the spring telescopic rod at the bottom of the bearing bottom plate carry out elastic buffering to weaken the vibration of the battery. When the telescopic hose elastically expands and contracts, it can conduct the heat generated by the battery downward, and discharge the heat to the heat collecting plate through the air guide nozzle to avoid heat reflux to the surrounding of the battery and ensure that the battery maintains efficient power supply. 3. The lower pressing plate abuts against the upper surface of the upper-layer battery. When extrusion occurs due to the abutment, elastic extrusion is carried out through the two pressing rods inside the spring tube sleeve, changing the length and angle between the pressing rod and the spring tube sleeve, so that the lower pressing plate can automatically move up and down to press the upper surface of the battery located in the upper layer inside the protection box to avoid shaking of the upper-layer battery during movement.

Detailed implementation manners

[0020] The present invention will be further described below with reference to the accompanying drawings: Embodiment

[0021] As shown in the Figure 1 to the Figure 6 accompanying drawings: The present invention discloses an adjustable new energy vehicle battery protection device, which structure includes a base 1, a protection box 2, and a top cover 3. The lower end of the protection box 2 is fixedly installed on the upper surface of the base 1, and the top cover 3 is installed on the upper end of the protection box 2. The edge of the base 1 is provided with a locking plate 11 to fix the base 1 with the chassis of the vehicle. The corners of the protection box 2 are provided with a connecting mechanism 21, and the protection box 2 is provided with a partition 22. The lower end of the fixing column 212 provided on the connecting mechanism 21 is fixed inside the corners of the protection box 2. The fixing column 212 is fixed inside the corners of the protection box 2. The upper end is embedded in the external tube 211 of the connecting mechanism 21, and a spring 214 is installed between the fixing column 212 and the external tube 211. A limit ring 213 is fixedly installed at the lower end of the external tube 211, and a sleeve ring 216 is slidably installed on the outer side of the external tube 211. The sleeve ring 216 abuts against the upper surface of the limit ring 213. An inner plate 217 is welded on the outer surface of the sleeve ring 216, and the inner plate 217 is welded to the corner end of the partition 22. A plurality of heightening pads 222 are also installed on the upper surface of the partition 22 to raise the bottom of the battery. Four partition plates 221 are equidistantly arranged inside the partition 22, and four batteries are independently supported by the four partition plates 221. A groove bar runs through the inside of each partition plate 221 to dissipate the heat generated by the battery. A clamping rod 223 is arranged at both ends of the partition 22, and the clamping rod 223 is plugged into the plug-in slots 23 arranged on both sides of the inside of the protection box 2. A bearing bottom plate 26 is movably installed at the bottom of the inner side of the protection box 2, and a telescopic hose 261 is also arranged at the bottom of the bearing bottom plate 26. The outside of the telescopic hose 261 is connected with a spring telescopic spring. Rod 2612, and an air guide nozzle 2611 is arranged at the bottom of the telescopic hose 261, and the air guide nozzle 2611 is connected to the heat collecting plate 13 at the bottom of the base 1, and a contact plate 24 is installed inside the protection box 2, and the back axis of the contact plate 24 is connected to a transverse linkage plate 241, and the other end of the transverse linkage plate 241 is connected to a sliding block 242, and the sliding block 242 is slidably installed on the outside of the spring guide rod 243 arranged inside the protection box 2, and a limit plate 25 is slidably installed inside the protection box 2, and a limit strip 251 is welded on the top of the limit plate 25; In the present invention, during the process of installing the batteries inside the protective box 2, the batteries in the lower layer are supported by the bearing bottom plate 26 at the bottom of the inner side of the protective box 2. After the batteries in the lower layer are installed, the four sleeve rings 216 are then slid downward from the top of the four external tubes 211, and the partition 22 is installed in the middle layer inside the protective box 2 through the interference and limitation of the limit ring 213. At this time, the partition 22 is located above the batteries in the lower layer. Then, the batteries in the upper layer are installed, and the bottom of the batteries in the upper layer is supported by the partition plate 221. The batteries on the upper and lower sides of the protective box 2 are separated and placed by the partition plate 22. At the same time, the spring 214 installed between the fixed column 212 and the external tube 211 is elastically supported to reduce vibration of the sleeve ring 216, thereby reducing vibration of the partition 22 as a whole, and avoiding collision when the batteries are stacked. During the installation process, the contact plate 24 contacts and squeezes the surface of the battery. The lateral linkage plate 241 is linked in the opposite direction, so that the two sliding blocks 242 slide in the opposite direction on the spring guide rod 243. At the same time, the spring guide rod 243 applies a reverse elastic force to the sliding block 242, so that the contact plate 24 elastically contacts the battery surface. The front and rear ends of batteries of different sizes are contacted by the front and rear contact plates 24 of the two groups, thereby improving the firmness of the battery installed inside the protective box 2 and reducing the shaking during movement. When the protective box 2 vibrates during movement, the battery squeezes the supporting bottom plate 26. At this time, the telescopic hose 261 and the spring telescopic rod 2612 at the bottom of the supporting bottom plate 26 perform elastic buffering to reduce the vibration of the battery. When the telescopic hose 261 is elastically extended, the heat generated by the battery can be conducted downward, and the heat is discharged to the heat collecting plate 13 through the air guide nozzle 2611 to prevent the heat from flowing back to the battery, thereby ensuring that the battery maintains efficient power supply.

[0022] A preferred technical solution, the sleeve ring 216 and the internal connecting plate 217 are provided with four, and are distributed at the four corner ends of the partition 22. The four sleeve rings 216 are adjusted and slid on the four external pipes 211 inside the four corners of the protection box 2, so that the partition 22 can be placed horizontally and smoothly in the middle position inside the protection box 2, so that the batteries on the upper and lower sides of the protection box 2 are separated and placed. At the same time, the spring 214 installed between the fixed column 212 and the external pipe 211 is elastically supported to reduce the vibration of the sleeve ring 216, thereby reducing the vibration of the partition 22 as a whole, and avoiding collision when the batteries are stacked; A preferred technical solution, the clamping rod 223 is made of metal material, has a certain elasticity, and the upper end of the clamping rod 223 is bent, and the clamping rods 223 on both sides are inserted and installed in the insertion slots 23 on both sides of the protection box 2, which can improve the firmness of the partition 22 placed in the middle layer of the protection box 2, and the partition 22 can be easily taken out from the protection box 2 by pulling up the clamping rods 223 on both sides; A preferred technical solution is that twelve groove strips penetrate through the inside of the bearing bottom plate 26, and three of them form a group. The bearing bottom plate 26 supports the four batteries in the lower layer, and the groove strips dissipate the heat generated by the batteries. At the same time, when the protection box 2 vibrates, the batteries squeeze the bearing bottom plate 26. At this time, the telescopic hose 261 and the spring telescopic rod 2612 at the bottom of the bearing bottom plate 26 perform elastic buffering to weaken the vibration of the batteries. When the telescopic hose 261 elastically expands and contracts, it can conduct the heat generated by the batteries downward, and discharge the heat to the heat collecting plate 13 through the air guide nozzle 2611, avoiding the heat from flowing back to the surroundings of the batteries and ensuring that the batteries maintain efficient power supply; A preferred technical solution is that two sliding blocks 242 and two transverse linkage plates 241 are provided, and they are distributed left and right. When the contact plate 24 contacts the surface of the battery and is subjected to pressure, the two transverse linkage plates 241 move in the reverse direction, causing the two sliding blocks 242 to slide in the reverse direction on the spring guide rod 243. At the same time, the spring guide rod 243 applies a reverse elastic force to the sliding blocks 242, so that the contact plate 24 elastically contacts the surface of the battery. The front and rear groups of contact plates 24 contact the front and rear ends of different-sized batteries to improve the firmness of the battery installed inside the protection box 2 and reduce the shaking generated during the movement; A preferred technical solution is that the limiting strip 251 limits the up and down sliding of the limiting plate 25. When the partition plate 22 needs to be installed or disassembled, after pushing the contact plate 24 into the protection box 2, the upper end of the front surface of the contact plate 24 is contacted and limited by the limiting plate 25, so that the contact plate 24 is retracted and fixed inside the protection box 2, thereby preventing the contact plate 24 from blocking the up and down movement stroke of the partition plate 22. Example 2: On the basis of Example 1, as shown in the attached Figure 7 to the attached Figure 8 shown: A flat head screw 31 penetrates through the top cover 3. The lower end of the flat head screw 31 is locked inside the threaded pipe 215 provided at the top of the outer connection pipe 211. The lower end surface of the top cover 3 is welded with a plug-in rod 32, and the lower end of the plug-in rod 32 is inserted and installed inside the plug-in pipe 12 installed on the upper surface of the base 1. The plug-in rod 32 and the plug-in pipe 12 are both attached to the outer surface of the protection box 2. A lower pressing plate 33 is also installed in the middle of the bottom of the top cover 3. A pressing rod 331 is axially connected to the upper surface of the lower pressing plate 33, and the upper end of the pressing rod 331 is connected to a spring tube sleeve 332; In the present invention, after the battery is installed inside the protection box 2, the top cover 3 is placed above the protection box 2. While being locked inside the four threaded tubes 215 by four flat head screws 31, a plurality of insertion rods 32 are respectively inserted into corresponding insertion tubes 12, improving the positioning accuracy and firmness of the installation among the base 1, the protection box 2 and the top cover 3. Moreover, after the insertion rods 32 and the insertion tubes 12 are installed, they fit against the protection box 2 to provide anti-collision protection during movement, enhancing the protection effect of the protection box 2 on the internal battery. Additionally, the lower pressing plate 33 abuts against the upper surface of the upper layer battery. When extrusion occurs during the abutment, elastic extrusion is performed through two extrusion rods 331 inside the spring tube sleeves 332, changing the length and angle between the extrusion rods 331 and the spring tube sleeves 332, enabling the lower pressing plate 33 to automatically adjust up and down to press the upper surface of the battery located in the upper layer inside the protection box 2, preventing the upper layer battery from shaking during movement.

[0023] In a preferred technical solution, there are four flat head screws 31, which are distributed at the four corner ends of the top cover 3. While being locked inside the four threaded tubes 215 by the four flat head screws 31, a plurality of insertion rods 32 are respectively inserted into corresponding insertion tubes 12, improving the positioning accuracy and firmness of the installation among the base 1, the protection box 2 and the top cover 3. Moreover, after the insertion rods 32 and the insertion tubes 12 are installed, they fit against the protection box 2 to provide anti-collision protection during movement, enhancing the protection effect of the protection box 2 on the internal battery; In a preferred technical solution, there are four extrusion rods 331 and two spring tube sleeves 332. Two extrusion rods 331 and one spring tube sleeve 332 form a group, which are respectively arranged between the middle of the bottom of the top cover 3 and the left and right sides of the upper end of the lower pressing plate 33. The two extrusion rods 331 in each group respectively pass through the head and tail ends of the spring tube sleeve 332 with clearance fit. Through elastic extrusion of the two extrusion rods 331 inside the spring tube sleeve 332, the length and angle between the extrusion rods 331 and the spring tube sleeves 332 are changed, enabling the lower pressing plate 33 to automatically adjust up and down to press the upper surface of the battery located in the upper layer inside the protection box 2, preventing the upper layer battery from shaking during movement. Using the technical solution of the present invention, or those skilled in the art being inspired by the technical solution of the present invention to design similar technical solutions and achieving the above technical effects shall fall within the protection scope of the present invention.
