Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically a battery box gripping device for battery swapping in new energy vehicles. Background Technology

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels, and the battery box of a new energy vehicle is the core component that supports and protects the power battery system of a new energy vehicle. With the development of technology, the battery box industry will also usher in huge market demand growth.

[0003] In the battery swapping process of new energy vehicle battery boxes, the gripping mechanism is the core execution component for realizing the automated, safe and efficient transfer of battery boxes. New energy vehicle battery boxes generally have the characteristics of being "heavy, large and with special structures", which directly eliminates the feasibility of manual handling and can only rely on the gripping mechanism to achieve physical transfer.

[0004] The prior art patent document CN217575141U provides a battery box gripping device for battery swapping of new energy vehicles. This gripping device effectively avoids the battery box shaking during hoisting, which may cause safety hazards. At the same time, it can stabilize the battery box and facilitate positioning during battery swapping operations.

[0005] While the aforementioned prior art allows the battery box to remain stable during hoisting and facilitates positioning during battery swapping, it only works on battery boxes with gripping beams. However, not all battery boxes on the market have gripping beams, and most are square, making it impossible to directly lift and grip the bottom of the battery box. This reduces the applicability of the gripping device. Therefore, we need a battery box gripping device for new energy vehicle battery swapping. Utility Model Content

[0006] The purpose of this utility model is to provide a battery box gripping device for battery swapping in new energy vehicles, so as to solve the problem mentioned in the background art that not all battery boxes are equipped with gripping beams, which reduces the applicability of the gripping device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A battery box gripping device for battery swapping in new energy vehicles includes a lifting plate, a device box is fixedly connected to the bottom of the lifting plate, and drive components are provided on both sides of the device box;

[0009] The drive assembly includes a drive motor, the output end of which is detachably connected to a main gear via a coupling, and a secondary gear meshes with the outer wall of the main gear. A threaded rod is fixedly connected to the inner wall of the secondary gear, and a drive block is threadedly connected to the outer surface of the threaded rod. A gripper assembly is installed at the bottom of the drive block.

[0010] The gripper assembly includes a fixed base, a rotating gripper hinged to the bottom of the fixed base, an electric push plate mounted on one side of the rotating gripper, a return spring fixedly connected to one side of the rotating gripper, a force plate mounted on one end of the return spring, a pressing motor inside the rotating gripper, and a transmission screw detachably connected to the output end of the pressing motor via a coupling, with a pressing plate threaded onto the outer surface of the transmission screw.

[0011] Preferably, the top of the lifting plate is provided with an equipment connecting plate, and a lifting mechanism is installed between the lifting plate and the equipment connecting plate for adjusting the gripping height.

[0012] Preferably, the main gear and the auxiliary gear are arranged to mesh perpendicularly to each other, and there are two auxiliary gears. The two auxiliary gears are symmetrically distributed with the axis of the main gear as the center of symmetry, so as to ensure that when the main gear rotates, it can drive the two auxiliary gears to rotate synchronously in opposite directions.

[0013] Preferably, a fall arrestor block is fixedly connected to the top of the drive block, a guide rod is slidably connected to the inner wall of the drive block, and one end of the guide rod passes through the inner wall of the equipment box. There are two threaded rods, and the threads of the two threaded rods have the same direction. The external thread of the threaded rod matches the internal thread of the drive block. The fall arrestor block is T-shaped and is engaged in a groove on the inner wall of the hoisting plate, and can slide left and right along the groove.

[0014] Preferably, the bottom of the fixed base and the top of the rotating gripper are hinged to each other, and the electric push plate is disposed between the fixed base and the rotating gripper. The two ends of the electric push plate are respectively hinged to the fixed base and the rotating gripper. The inner side of the rotating gripper is machined into a beveled surface. This beveled surface structure allows the rotating gripper to smoothly cut into the bottom of the battery box and achieve stable gripping.

[0015] Preferably, a movable rod is fixedly connected to one side of the force plate, and one end of the movable rod passes through the side wall of the rotating gripper and the inner cavity of the return spring in sequence, and is finally fixedly connected to the force plate. There are three return springs, and the three return springs are arranged linearly at equal distances along one side of the force plate to ensure that the force plate is subjected to uniform force.

[0016] Preferably, the external thread on the outer wall of the transmission screw matches the internal thread on one side of the pressing plate, and an anti-slip pad is adhered to the bottom of the pressing plate. This anti-slip pad can effectively increase the friction between the pressing plate and the surface of the battery box, preventing the battery box from slipping during the gripping process.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this battery box gripping device for battery swapping in new energy vehicles,

[0018] This invention utilizes the rotation of the main gear within the drive assembly to drive two counter-gears to rotate in opposite directions. This, in turn, causes two threaded rods to rotate in opposite directions, which in turn move two drive blocks relative to each other. This, in turn, moves the rotating grippers at the bottom relative to each other, gripping the sides of the battery box. An electric push plate pushes the rotating grippers outwards, allowing their beveled surfaces to cut into the bottom of the battery box. After extending a certain distance, the electric push plate resets, causing the rotating grippers to lift the battery box. During the inward gripping process of the two rotating grippers, the sides of the battery box contact the force plate, compressing the return spring. This compression stops the drive motor. Finally, driven by a pressing motor, the transmission screw moves the pressing plate downwards, pressing down to fix the sides of the battery box. Combined with anti-slip pads to increase friction with the battery box surface, this invention solves the problem of dependence on specific battery box structures in existing technologies and significantly improves the adaptability of the gripping device to different types of battery boxes on the market.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A battery box grabbing device for battery swapping of new energy vehicles includes a lifting plate 1, an equipment box 2 is fixedly connected to the bottom of the lifting plate 1, and drive components 3 are provided on both sides of the equipment box 2.

[0026] The drive assembly 3 includes a drive motor 301. The output end of the drive motor 301 is detachably connected to a main gear 302 via a coupling. A secondary gear 303 meshes with the outer wall of the main gear 302. A threaded rod 304 is fixedly connected to the inner wall of the secondary gear 303. A drive block 305 is threadedly connected to the outer surface of the threaded rod 304. A gripper assembly 4 is installed at the bottom of the drive block 305.

[0027] The gripper assembly 4 includes a fixed base 401, a rotating gripper 402 hinged to the bottom of the fixed base 401, an electric push plate 403 mounted on one side of the rotating gripper 402, a return spring 404 fixedly connected to one side of the rotating gripper 402, a force plate 405 mounted on one end of the return spring 404, a pressing motor 407 disposed inside the rotating gripper 402, and a transmission screw 408 detachably connected to the output end of the pressing motor 407 via a coupling, and a pressing plate 409 threadedly connected to the outer surface of the transmission screw 408.

[0028] Through the above technical solutions, a complete and efficient battery box gripping execution framework was constructed. Among them, the lifting plate 1 is made of high-strength alloy material, which not only provides stable support for all the components below, such as the equipment box 2 and the drive component 3, but also can withstand the heavy pressure of the new energy vehicle battery box and avoid deformation after long-term use. The equipment box 2 is a closed structure with reserved mounting slots for the main gear 302, the auxiliary gear 303 and the threaded rod 304. This protects the core transmission components from dust and oil corrosion, extends the service life of the components, and prevents foreign objects from being caught in the transmission process and causing failure. The drive component 3, as the power core, can convert the rotational power of the drive motor 301 into the linear movement power of the gripper component 4 through gear meshing and thread transmission, ensuring that the gripper action responds quickly. Finally, the gripper component 4 directly contacts the battery box to complete the gripping action. The overall structure has a clear division of labor and tight connection, providing a core execution foundation for the automated operation of the battery swapping station.

[0029] Specifically, the top of the lifting plate 1 is provided with an equipment connecting plate 5, and a lifting mechanism 6 is installed between the lifting plate 1 and the equipment connecting plate 5 for adjusting the grabbing height.

[0030] Through the above technical solution, the equipment connection plate 5 is designed with standardized bolt holes, which can be quickly connected with various hoisting or mobile equipment such as gantry cranes and mobile robotic arms of the battery swapping station without the need for separate modifications for different equipment, thus reducing the equipment adaptation cost of the battery swapping station. The lifting mechanism 6 adopts a hoisting rope and hydraulic drive method, which can drive the hoisting plate 1 to move up and down, thereby driving the gripper assembly 4 to accurately match the height of the battery compartment. When docking with the battery box storage compartment, whether it is the bottom storage position or the top storage position, the gripper can be horizontally aligned with the battery box through height adjustment, avoiding misalignment due to unsuitable height, and significantly improving the adaptability of the device to the battery swapping needs of multiple vehicle models and multiple storage scenarios.

[0031] Specifically, the main gear 302 and the auxiliary gear 303 are arranged to mesh perpendicularly to each other, and there are two auxiliary gears 303. The two auxiliary gears 303 are symmetrically distributed with the axis of the main gear 302 as the center of symmetry, so as to ensure that when the main gear 302 rotates, it can drive the two auxiliary gears 303 to rotate synchronously in opposite directions.

[0032] Through the above technical solution, both the main gear 302 and the auxiliary gear 303 are made of hardened gear steel. The two auxiliary gears 303 are symmetrically distributed with the axis of the main gear 302 as the center of symmetry. This layout allows the two auxiliary gears 303 to obtain equal and opposite torques when the main gear 302 rotates. This, in turn, drives the two threaded rods 304 to rotate synchronously in opposite directions at the same speed. Combined with the precise thread matching between the threaded rods 304 and the drive block 305, the two gripper assemblies 4 can be driven to move precisely towards or away from each other at the same speed. This ensures that the grippers always apply force to the center position of the battery box, avoiding problems such as battery box offset and shaking caused by asynchronous movement on both sides. This significantly improves the stability of the gripping process, and is especially suitable for new energy vehicle battery boxes that are heavy and have a sensitive center of gravity. It achieves high-precision synchronous movement of the gripper assembly 4, ensuring gripping stability from the power source level.

[0033] Specifically, a fall arrestor block 306 is fixedly connected to the top of the drive block 305, and a guide rod 307 is slidably connected to the inner wall of the drive block 305. One end of the guide rod 307 passes through the inner wall of the equipment box 2. There are two threaded rods 304, and the threads of the two threaded rods 304 have the same direction. The external thread of the threaded rod 304 matches the internal thread of the drive block 305. The fall arrestor block 306 is T-shaped and is engaged in the groove on the inner wall of the hoisting plate 1, and can slide left and right along the groove.

[0034] Through the above technical solution, on the one hand, the guide slide rod 307 is made of chrome-plated round steel, which passes through the sliding hole of the drive block 305 and is welded and fixed to the inner wall of the equipment box 2. This design restricts the drive block 305 to move linearly only along the axis of the guide slide rod 307, completely avoiding the displacement of the drive block 305 due to the radial force of the threaded rod 304, and ensuring the precise movement trajectory of the gripper assembly 4. On the other hand, the T-shaped anti-fall block 306 is integrally formed with the top of the drive block 305, and its lateral protrusion is engaged in the T-shaped sliding groove on the inner wall of the lifting plate 1. It can slide smoothly synchronously with the drive block 305, and can also bear the total weight of the drive block 305, the gripper assembly 4 below, and the battery box in extreme cases, preventing the drive block 305 from falling accidentally and causing equipment damage or safety accidents. The dual design forms a "precise guidance and safe anti-fall" guarantee system, ensuring the stable and safe movement of the drive block 305 and providing solid support for the reliable operation of the gripper assembly 4.

[0035] Specifically, the bottom of the fixed base 401 is hinged to the top of the rotating gripper 402, and the electric push plate 403 is disposed between the fixed base 401 and the rotating gripper 402. The two ends of the electric push plate 403 are hinged to the fixed base 401 and the rotating gripper 402 respectively. The inner side of the rotating gripper 402 is machined into a beveled surface. This beveled surface structure allows the rotating gripper 402 to smoothly cut into the bottom of the battery box and achieve stable gripping.

[0036] Through the above technical solution, the hinge between the fixed base 401 and the rotating gripper 402 is connected by a high-precision bearing, and the rotational damping is adjustable to ensure that the rotating gripper 402 rotates flexibly and without looseness. The electric push plate 403 uses a miniature electric push rod, which can accurately push the rotating gripper 402 to rotate around the hinge point when it is extended or retracted. When it is necessary to grasp a square battery box without a gripping beam, the electric push plate 403 extends and pushes the rotating gripper 402 to unfold outward. At this time, the beveled surface machined on the inner side of the rotating gripper 402 can smoothly cut into the bottom of the battery box and place it like a "shovel". The gap between the surfaces allows the electric push plate 403 to retract and reset after the beveled surface extends into the bottom of the battery box. The rotating gripper 402 rotates inward around the hinge point, which can steadily lift the battery box and achieve the lifting and gripping of square battery boxes without gripping beams. This design perfectly solves the core pain point of only being able to grip battery boxes with gripping beams and having low adaptability. It enables the device to cover most mainstream square battery boxes on the market, reduces the limitation threshold of battery box structure for battery swapping stations, completely breaks through the structural dependence of existing devices on the "gripping beam" of battery boxes, and greatly expands the adaptability range of the device.

[0037] Specifically, a movable rod 406 is fixedly connected to one side of the force plate 405, and one end of the movable rod 406 passes through the side wall of the rotating gripper 402 and the inner cavity of the return spring 404 in sequence, and is finally fixedly connected to the force plate 405. There are three return springs 404, and the three return springs 404 are arranged linearly at equal distances along one side of the force plate 405 to ensure that the force plate 405 is subjected to uniform force.

[0038] Through the above technical solution, the movable rod 406 is made of stainless steel, with the other end passing through the guide hole of the rotating gripper 402 and extending outwards, ensuring that the force plate 405 can only move along the axis of the movable rod 406, avoiding deviation when subjected to force. The three return springs 404 are cylindrical helical return springs with high elastic coefficient, arranged linearly at equal intervals along one side of the force plate 405, and the two ends of the return springs 404 are welded and fixed to the rotating gripper 402 and the force plate 405 respectively. When the gripper assembly 4 moves towards the battery box, the force plate 405 will first contact the side wall of the battery box, and as the gripper continues to move... When the return spring 404 is compressed, the rigid impact force during the clamping process can be converted into the elastic potential energy of the return spring 404, effectively offsetting the impact force. At the same time, the three equidistantly distributed return springs 404 can ensure that the force plate 405 is evenly stressed at all points, avoiding deformation, cracking, or even damage to the internal cells of the battery box due to excessive local pressure. This flexible protection design is especially suitable for new energy vehicle battery boxes, providing key protection for the structural safety of the battery box during the gripping process, and providing flexible clamping protection of "directional buffering and uniform force" for the battery box, avoiding damage caused by rigid contact.

[0039] Specifically, the external thread on the outer wall of the transmission screw 408 matches the internal thread on one side of the pressing plate 409, and an anti-slip pad is bonded to the bottom of the pressing plate 409. This anti-slip pad can effectively increase the friction between the pressing plate 409 and the surface of the battery box, preventing the battery box from slipping during the gripping process.

[0040] Through the above technical solution, the transmission screw 408 adopts a trapezoidal thread structure and its surface is treated with wear resistance. The other end is connected to the bearing seat inside the rotating jaw 402 through a bearing, ensuring that the transmission screw 408 rotates smoothly without jamming. The pressing plate 409 is made of high-strength engineering plastic material, and one side of it is machined with an internal thread hole that matches the transmission screw 408. It can move up and down along the axis of the transmission screw 408. When the rotating jaw 402 lifts the battery box, the pressing motor 407 starts, driving the transmission screw 408 to rotate clockwise. The pressing plate 409 moves down along the axis of the transmission screw 408 until it is in close contact with the top of both sides of the battery box, thus pressing the battery box. The downward pressure further restricts the vertical displacement of the battery box. Combined with the lifting force of the rotating gripper 402, a double fixation of "bottom support and top pressure" is formed. At the same time, the anti-slip pads attached to the bottom of the pressing plate 409 can significantly increase the friction with the surface of the battery box. Even if there is slight tilting or vibration during the gripping process, it can effectively prevent the battery box from slipping and falling off. This "secondary fixation and anti-slip" design completely solves the problem of the battery box slipping and shaking during the gripping process. It is especially suitable for complex working conditions such as high-altitude transfer and long-distance movement, and achieves the dual protection of "secondary fixation and anti-slip and anti-detachment" for the battery box, further improving the gripping stability.

[0041] Working principle: When using this battery box gripping device for new energy vehicle battery swapping, firstly, the electric push plate 403 in the gripper assembly 4 is activated. When it extends, it pushes the rotating gripper 402 to rotate outward around the hinge point of the fixed base 401, ensuring that the beveled surface on the inner side of the rotating gripper 402 can be aligned with the gap between the bottom of the battery box and the placement surface. The device is then moved as a whole by external hoisting equipment, so that the extended rotating gripper 402 moves closer to the battery box until the beveled surface on the inner side of the rotating gripper 402 completely cuts into the gap at the bottom of the battery box. Then, the drive assembly 3 is activated. The drive motor 301 drives the main gear 302 to rotate. When the main gear 302 rotates, it drives the two auxiliary gears 303 to rotate synchronously in opposite directions. This, in turn, drives the two threaded rods 304, which are fixed to the inner wall of the auxiliary gears 303, to rotate synchronously in opposite directions. When the threaded rods 304 rotate in opposite directions, they drive the drive blocks 305 on both sides and the gripper assembly 4 at the bottom to move towards each other, gradually approaching the sides of the battery box. After the beveled surface extends into the bottom of the battery box, the electric push plate 403 is controlled to retract and reset. The rotating gripper 402 is then positioned on the electric push plate 403. Under the pull, the rotating jaws rotate inward around the hinge point, steadily lifting the battery box and completing the initial lifting. When the gripper assembly 4 approaches the battery box to a certain distance, the force plate 405 on one side of the rotating jaw 402 first contacts the side wall of the battery box. As the jaws continue to move, the force plate 405 compresses the three equidistant return springs 404 on one side through the movable rod 406. The elastic deformation can offset the rigid impact force during the clamping process. At the same time, the three equidistant return springs 404 ensure that the force plate 405 is evenly stressed, avoiding local pressure deformation of the battery box shell. Finally, the rotating jaws are activated. The internal pressing motor 407 of 402 drives the transmission screw 408 to rotate clockwise via a coupling. When the transmission screw 408 rotates, it drives the pressing plate 409 to move axially downward until the bottom of the pressing plate 409 is in close contact with the top of both sides of the battery box, forming a double fixation of "bottom support and top pressure". At the same time, the anti-slip pad at the bottom of the pressing plate 409 is in close contact with the surface of the battery box, greatly increasing the friction. This completes the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
