Description

Technical Field

[0001] The present invention relates to the technical field of new energy batteries, and more specifically, to a new energy battery box assembly. Background Art

[0002] With the popularization of electric new energy vehicles, the battery assembly, as a core component, has also received great attention. To protect the new energy vehicle battery, it is necessary to place the new energy vehicle battery inside the battery box. In the process of fixing the new energy battery by the existing battery box, the battery is fixed by a locking method, which will cause certain damage to the battery. The battery is in close contact with the box body, and it is easy to damage the battery when being impacted. Moreover, the heat dissipation performance is poor, and the heat generated by the battery is easily accumulated inside the battery box, affecting the battery life. In addition, it is not convenient to quickly take out the battery for maintenance, the operation is inconvenient, and it is not easy to use. Therefore, it is necessary to provide a new energy battery box assembly to solve the problems raised in the above background art. Summary of the Invention

[0003] To achieve the above object, the present invention provides the following technical solution: A new energy battery box assembly, comprising:

[0004] A box body, which is the main component of the battery box;

[0005] A box cover, arranged on the top of the box body;

[0006] An auxiliary clamping assembly, arranged inside the box body, symmetrically distributed in two groups, and attached to the inner walls on both sides;

[0007] A rotating assembly, arranged on the side of the box body and connected to the auxiliary clamping assembly;

[0008] A top fixing assembly, fixedly connected to the top of the box cover and the bottom of the box body respectively at its upper and lower ends;

[0009] A battery body, arranged between the auxiliary clamping assembly and the top fixing assembly;

[0010] An elastic member, fixed to the bottom of the battery body.

[0011] Further, as a preference, the box body includes:

[0012] A front box wall, on which a rotating surface is provided, and a fixed limiting surface is provided on the front box wall below the rotating surface;

[0013] A rear box wall, arranged parallel to the front box wall, and a telescopic limiting surface opposite to the fixed limiting surface is provided at the lower part;

[0014] The side box wall connects the front box wall and the rear box wall, and has an arc-shaped tooth track on the inner wall, and the arc-shaped tooth track is connected to the side surface of the top fixing component. That is to say, through the rotation of the rotating surface, the battery body is driven to be in an inclined state in the box body, and under the action of the elastic member, the battery body moves upward, facilitating the installation and disassembly of the battery body.

[0015] Further, as a preference, the bottoms of the fixed limiting surface and the telescopic limiting surface are on the same horizontal plane as the bottom of the battery body, and the bottom of the side arc surface fits with the top of the side arc surface of the elastic member. When the rotating surface drives the battery body to tilt, the elastic member is simultaneously driven to tilt. The side on the fixed limiting surface moves downward, and the side on the telescopic limiting surface moves upward, compressing the telescopic limiting surface and moving to the upper part of the telescopic limiting surface. Then, the elastic member is released from the restriction of the two limiting surfaces, and during the rotation process, restricted by the bottom of the box body, the elastic member rebounds, driving the battery body to move upward, so that the staff can take out the battery body. It should be noted that the maximum elongation distance of the elastic member is the same as the distance between the limiting surface and the bottom of the box body, so that when the rotating surface drives the battery body to reset, the elastic member gradually loses the reverse force from the bottom of the box body, causing the battery body to move downward, and at the same time, with the assistance of the top fixing component, the battery body is fixed inside the box body.

[0016] Further, as a preference, the auxiliary clamping component includes:

[0017] Side positioning plates, two of which are symmetrically distributed and are attached to both sides of the battery body;

[0018] Auxiliary rolling components, which are arranged on both sides of the battery body and are fixed at both ends of the side positioning plates;

[0019] Rotating side walls, which are fixed on the inner wall of the rotating surface, and the top is fixedly connected to one end of the side positioning plate;

[0020] Active rolling components, which are fixed at the lower part of the rotating side walls and are connected to the rotating component. Under the action of the side positioning plates and the auxiliary rolling components, the front and rear sides of the battery body are restricted. And under the action of the side positioning plates, when the rotating component drives the rotating side walls and the rotating surface to rotate, under the clamping action of the two auxiliary rolling components on both sides, the battery body rotates along with the rotating surface to achieve the purpose of tilting the battery body. And when the rotating component drives the active rolling components alone, through the mutual cooperation of the active rolling components and the auxiliary rolling components, the battery body can be moved up and down for a short distance to assist in the installation and disassembly of the battery body.

[0021] Further, as a preference, the auxiliary rolling component includes:

[0022] Auxiliary rollers, three of which are annularly distributed, and two of the auxiliary rollers are in contact with the battery body;

[0023] The connecting frame is fixed on the side positioning plate and is connected to the auxiliary roller through a shaft body, and the shaft body is rotatably connected to the auxiliary roller. The position of the auxiliary rolling assembly is restricted by the connecting frame, and two relatively stable force points are formed on the battery body by the two auxiliary rollers, effectively avoiding the deflection of the battery body around the auxiliary roller under the stressed state and improving the overall stability of the equipment.

[0024] Further, as a preference, the active rolling assembly includes:

[0025] Drive rollers, three of which are annularly distributed, with a shaft body fixed in the middle, and two of the drive rollers are in contact with the battery body;

[0026] The limit frame is arranged on one side of the drive roller;

[0027] The fixed frame is fixedly connected to the rotating side wall and the limit frame respectively on both sides;

[0028] The central gear is arranged at the center of the limit frame and is fixedly connected to the rotating assembly;

[0029] The surrounding gear is fixed on the shaft body in the middle of the drive roller and meshes with the central gear. When the rotating assembly drives the central gear to rotate, the shaft body is driven to rotate through the surrounding gear, and then the drive roller is driven to rotate, driving the battery body to move a short distance with the assistance of the auxiliary rolling assembly; when the rotating assembly drives the rotating side wall to rotate, under the action of the fixed frame, the whole active rolling assembly rotates with the rotating side wall, and then the auxiliary clamping assembly drives the battery body to rotate.

[0030] Further, as a preference, the rotating assembly includes:

[0031] The rotating inner shaft connects the micro motor arranged inside the side box wall and the central gear;

[0032] The rotating outer shaft is rotatably arranged on the rotating inner shaft, is fixedly connected to the rotating side wall, and is connected to a power source different from the rotating inner shaft;

[0033] The transmission sprocket is fixed on the rotating outer shaft and is connected to the top fixing component. When the rotating inner shaft rotates, the drive roller on the active rolling assembly is driven to rotate through the central gear; when the rotating outer shaft rotates clockwise, while driving the rotating side wall to rotate outward, the top fixing component is driven to move through the transmission sprocket, and the box cover is lifted, and at this time the battery box is in an open state. When the rotating outer shaft rotates counterclockwise, while driving the rotating side wall to reset, the top fixing component is driven to move through the transmission sprocket, driving the box cover to move downward, and at this time the battery box is in a closed state.

[0034] Further, preferably, the top fixing component includes:

[0035] An upper fixing member fixed to the bottom of the box cover;

[0036] A connecting rod located at the side of the battery body and connected to the upper fixing member;

[0037] A lower fixing member fixed to the top of the box body, located below the elastic member and connected to the connecting rod;

[0038] A rotating gear is arranged at the connection between the upper fixing member and the connecting rod, fixedly connected to the upper fixing member, rotatably connected to the connecting rod, and meshed with the arc-shaped tooth track;

[0039] A reverse gear set is arranged at the connection between the lower fixing member and the connecting rod, rotatably connected to the lower fixing member, fixedly connected to the connecting rod, and connected to the transmission sprocket through a chain. That is to say, when the rotating outer shaft drives the transmission sprocket to rotate clockwise, under the action of the chain, the reverse gear set drives the connecting rod to rotate counterclockwise on the lower fixing member. At the same time, under the action of the arc-shaped tooth track, the rotating gear drives the upper fixing member to rotate clockwise. Furthermore, when the upper fixing member, the connecting rod, and the lower fixing member are in the same vertical line, the upper fixing member jacks up the box cover, so that the battery body can be deflected under the drive of the rotating side wall, making the battery box in an open state, facilitating the replacement and maintenance of the battery body; when the rotating outer shaft drives the transmission sprocket to rotate counterclockwise, under the action of the chain, the reverse gear set drives the connecting rod to rotate clockwise on the lower fixing member. At the same time, under the action of the arc-shaped tooth track, the rotating gear drives the upper fixing member to rotate counterclockwise. Furthermore, the upper fixing member drives the box cover to move down. After the battery body rotates and resets following the rotating side wall, the top of the battery body is closed, making the battery box in a sealed state.

[0040] Further, preferably, the reverse gear set includes:

[0041] An outer fixing ring fixed inside the side box wall;

[0042] Two transmission bevel gears are symmetrically distributed and rotatably arranged inside the outer fixing ring;

[0043] A forward bevel gear meshes with the transmission bevel gear and is connected to the transmission sprocket through a chain;

[0044] A reverse bevel gear is arranged opposite to the forward bevel gear, meshes with the transmission bevel gear, and the central axis is fixedly connected to the connecting rod. That is to say, under the restriction of the outer fixing ring, when the transmission sprocket drives the forward bevel gear to rotate, under the transmission of the transmission bevel gear, the reverse bevel gear rotates in the opposite direction to the forward bevel gear.

[0045] Compared with the prior art, the beneficial effects of the present invention are:

[0046] In the present invention, through the setting of the auxiliary clamping assembly, the two sides of the battery are clamped by rolling. In the open state, it is convenient to install and remove the battery. In the closed state, it cooperates with the top fixing assembly to fix the battery. And under the action of the elastic member at the bottom, it can assist in removing the battery and also help maintain the stability of the battery under shaking. Moreover, there is a certain ventilation gap between the battery body and the box body, which helps to discharge heat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0054] Please refer to Figures 1 to 6 , in an embodiment of the present invention, a new energy battery box assembly includes:

[0055] The box body 1, which is the main component of the battery box;

[0056] The box cover 2 is arranged on the top of the box body 1;

[0057] The auxiliary clamping assembly 3 is arranged inside the box body 1, with two groups symmetrically distributed and fitting with the inner walls on both sides;

[0058] The rotating assembly 4 is arranged on the side of the box body 1 and is connected to the auxiliary clamping assembly 3;

[0059] The top fixing assembly 5 is fixedly connected to the bottom of the box cover 2 and the box body 1 at its upper and lower ends respectively;

[0060] The battery body 6 is arranged between the auxiliary clamping assembly 3 and the top fixing assembly 5;

[0061] The elastic member 7 is fixed to the bottom of the battery body 6.

[0062] In this embodiment, the box body 1 includes:

[0063] The front box wall 11, on which a rotating surface 111 is provided, and a fixed limiting surface 112 is provided on the front box wall 11 below the rotating surface 111;

[0064] The rear box wall 12 is arranged parallel to the front box wall 11, and a telescopic limiting surface 121 opposite to the fixed limiting surface 112 is provided at the lower part;

[0065] The side box wall 13 connects the front box wall 11 and the rear box wall 12, and an arc-shaped tooth track 131 is provided on the inner wall, and the arc-shaped tooth track 131 is connected to the side surface of the top fixing assembly 5. That is to say, by the rotation of the rotating surface 111, the battery body 6 is driven to be in an inclined state inside the box body 1, and under the action of the elastic member 7, the battery body 6 moves upward, facilitating the installation and disassembly of the battery body 6.

[0066] In this embodiment, the bottoms of the fixed limiting surface 112 and the telescopic limiting surface 121 are at the same horizontal plane as the bottom of the battery body 6, and the bottom of the side arc surface is in contact with the top of the side arc surface of the elastic member 7. When the rotating surface 111 drives the battery body 6 to tilt, it also drives the elastic member 7 to tilt. The side on the fixed limiting surface 112 moves downward, and the side on the telescopic limiting surface 121 moves upward, compressing the telescopic limiting surface 121 and moving to the upper part of the telescopic limiting surface 121. Then, the elastic member 7 is released from the restriction of the two limiting surfaces. During the rotation process, restricted by the bottom of the box body 1, the elastic member 7 rebounds, driving the battery body 6 to move upward, facilitating the staff to take out the battery body 6. It should be noted that the maximum elongation distance of the elastic member 7 is the same as the distance between the limiting surface and the bottom of the box body 1. So, when the rotating surface 111 drives the battery body 6 to reset, the elastic member 7 gradually loses the reverse force from the bottom of the box body 1, causing the battery body 6 to move downward. At the same time, with the assistance of the top fixing assembly 5, the battery body 6 is fixed inside the box body 1.

[0067] In this embodiment, the auxiliary clamping assembly 3 includes:

[0068] Two side positioning plates 31 are symmetrically distributed and are attached to both sides of the battery body 6;

[0069] The auxiliary rolling assemblies 32 are arranged on both sides of the battery body 6 and are fixed at both ends of the side positioning plates 31;

[0070] The rotating side walls 33 are fixed on the inner wall of the rotating surface 111, and the top is fixedly connected to one end of the side positioning plate 31;

[0071] The active rolling assemblies 34 are fixed at the lower part of the rotating side walls 33 and are connected to the rotating assembly 4. Under the action of the side positioning plates 31 and the auxiliary rolling assemblies 32, the front and rear sides of the battery body 6 are restricted. And under the action of the side positioning plates 31, when the rotating assembly 4 drives the rotating side walls 33 and the rotating surface 111 to rotate, under the clamping action of the two auxiliary rolling assemblies 32 on both sides, the battery body 6 rotates following the rotating surface 111 to achieve the purpose of tilting the battery body 6. When the rotating assembly 4 drives the active rolling assemblies 34 alone, through the mutual cooperation of the active rolling assemblies 34 and the auxiliary rolling assemblies 32, the battery body 6 can be moved up and down for a short distance to assist in the installation and disassembly of the battery body 6.

[0072] In this embodiment, the auxiliary rolling assembly 32 includes:

[0073] Three auxiliary rollers 321 are annularly distributed, and two of the auxiliary rollers 321 are in contact with the battery body 6;

[0074] The connecting frame 322 is fixed on the side positioning plate 31 and is connected to the auxiliary roller 321 through a shaft body, and the shaft body is rotatably connected to the auxiliary roller 321. The position of the auxiliary rolling assembly 32 is restricted by the connecting frame 322, and the two auxiliary rollers 321 form two relatively stable force points on the battery body 6, effectively preventing the battery body 6 from deflecting around the auxiliary roller 321 under a force state and improving the overall stability of the device.

[0075] In this embodiment, the active rolling assembly 34 includes:

[0076] Three driving rollers 341 are annularly distributed, and a shaft body is fixed in the middle. Two of the driving rollers 341 are in contact with the battery body 6;

[0077] The limiting frame 342 is arranged on one side of the driving roller 341;

[0078] The fixed frame 343 is fixedly connected to the rotating side wall 33 and the limiting frame 342 on both sides respectively;

[0079] The central gear 344 is arranged at the center of the limiting frame 342 and is fixedly connected to the rotating assembly 4;

[0080] The surrounding gear 345 is fixed on the shaft body in the middle of the driving roller 341 and meshes with the central gear 344. When the rotating assembly 4 drives the central gear 344 to rotate, the shaft body is driven to rotate through the surrounding gear 345, and then the driving roller 341 is driven to rotate, driving the battery body 6 to move a short distance with the assistance of the auxiliary rolling assembly 32; when the rotating assembly 4 drives the rotating side wall 33 to rotate, under the action of the fixed frame 343, the active rolling assembly 34 as a whole follows the rotating side wall 33 to rotate, and then the auxiliary clamping assembly 3 drives the battery body 6 to rotate.

[0081] In this embodiment, the rotating assembly 4 includes:

[0082] The rotating inner shaft 41 connects the micro motor arranged in the side box wall 13 and the central gear 344;

[0083] The rotating outer shaft 42 is rotatably arranged on the rotating inner shaft 41, is fixedly connected to the rotating side wall 33, and is connected to a power source different from the rotating inner shaft 41;

[0084] The driving sprocket 43 is fixed on the rotating outer shaft 42 and is connected to the top fixing assembly 5. When the rotating inner shaft 41 rotates, the driving roller 341 on the active rolling assembly 34 is driven to rotate by the central gear 344; when the rotating outer shaft 42 rotates clockwise, while the rotating outer shaft 42 drives the rotating side wall 33 to rotate outward, the top fixing assembly 5 is driven to move through the driving sprocket 43, and the box cover 2 is lifted. At this time, the battery box is in an open state. When the rotating outer shaft 42 rotates counterclockwise, while the rotating outer shaft 42 drives the rotating side wall 33 to reset, the top fixing assembly 5 is driven to move through the driving sprocket 43, driving the box cover 2 to move downward. At this time, the battery box is in a closed state.

[0085] In this embodiment, the top fixing assembly 5 includes:

[0086] The upper fixing member 51 is fixed to the bottom of the box cover 2;

[0087] The connecting rod 52 is located on the side of the battery body 6 and is connected to the upper fixing member 51;

[0088] The lower fixing member 53 is fixed to the top of the box body 1, located below the elastic member 7, and is connected to the connecting rod 52;

[0089] The rotating gear 54 is arranged at the connection of the upper fixing member 51 and the connecting rod 52, is fixedly connected to the upper fixing member 51, is rotatably connected to the connecting rod 52, and meshes with the arc-shaped tooth track 131;

[0090] The reverse gear set 55 is arranged at the connection of the lower fixing member 53 and the connecting rod 52, is rotatably connected to the lower fixing member 53, is fixedly connected to the connecting rod 52, and is connected to the driving sprocket 43 through a chain. That is to say, when the rotating outer shaft 42 drives the driving sprocket 43 to rotate clockwise, under the action of the chain, the reverse gear set 55 drives the connecting rod 52 to rotate counterclockwise on the lower fixing member 53. At the same time, under the action of the arc-shaped tooth track 131, the rotating gear 54 drives the upper fixing member 51 to rotate clockwise. Furthermore, when the upper fixing member 51, the connecting rod 52, and the lower fixing member 53 are in the same vertical line, the upper fixing member 51 lifts the box cover 2, so that the battery body 6 can be deflected under the drive of the rotating side wall 33, making the battery box in an open state, facilitating the replacement and maintenance of the battery body 6; when the rotating outer shaft 42 drives the driving sprocket 43 to rotate counterclockwise, under the action of the chain, the reverse gear set 55 drives the connecting rod 52 to rotate clockwise on the lower fixing member 53. At the same time, under the action of the arc-shaped tooth track 131, the rotating gear 54 drives the upper fixing member 51 to rotate counterclockwise. Furthermore, the upper fixing member 51 drives the box cover 2 to move downward. After the battery body 6 rotates and resets following the rotating side wall 33, the top of the battery body 6 is closed, making the battery box in a closed state.

[0091] In this embodiment, the reverse gear set 55 includes:

[0092] The external fixing ring 551 is fixed inside the side box wall 13;

[0093] There are two symmetrically distributed drive bevel gears 552, which are rotatably arranged inside the external fixing ring 551;

[0094] The forward bevel gear 553 meshes with the drive bevel gear 552 and is connected to the drive sprocket 43 through a chain;

[0095] The reverse bevel gear 554 is arranged opposite to the forward bevel gear 553, meshes with the drive bevel gear 552, and the central axis is fixedly connected to the connecting rod 52. That is to say, under the restriction of the external fixing ring 551, when the drive sprocket 43 drives the forward bevel gear 553 to rotate, under the transmission of the drive bevel gear 552, the reverse bevel gear 554 rotates in the direction opposite to that of the forward bevel gear 553.

[0096] During specific implementation, first, when overhauling or replacing the battery body 6, rotate the outer shaft 42 clockwise. Drive the rotating surface 111 and the auxiliary clamping assembly 3 to rotate outward of the box body 1 through the rotating side wall 33. Then the battery body 6 deflects and moves upward under the action of the bottom elastic member 7 and the rolling assembly. At the same time, under the action of the drive sprocket 43, the top fixing assembly 5 rotates to lift the box cover 2. Then drive the drive roller 341 to rotate by rotating the inner shaft 41 to assist in the taking and placing of the battery body 6. After the overhaul is completed, rotate the outer shaft 42 counterclockwise. Drive the rotating surface 111 and the auxiliary clamping assembly 3 to rotate inside the box body 1 through the rotating side wall 33. Then the battery body 6 rotates back to its original position. At the same time, under the action of the drive sprocket 43, the top fixing assembly 5 rotates back to its original position, driving the box cover 2 to move downward to seal the top of the battery body 6. And there is a certain ventilation gap between the battery body 6 and the box body 1, which helps to discharge heat.

[0097] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
