Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, specifically to a battery clamping and releasing device and a forklift. Background Technology

[0002] A forklift with a clip-on battery is an electric forklift characterized by a quick-replacement clip-on battery design. The battery pack is typically mounted on a dedicated rail or bracket at the rear or side of the forklift and secured by a mechanical locking device. This allows operators to directly remove the old battery and insert a fully charged spare when the old battery is depleted, without waiting for recharging, significantly improving continuous operation efficiency. The clip-on battery has a compact structure, supports standardized battery packs, facilitates centralized charging management and maintenance, and is suitable for high-intensity, multi-shift logistics scenarios. It also meets environmental protection requirements, reducing carbon emissions from traditional internal combustion forklifts.

[0003] In related technologies, battery replacement is often a complex and time-consuming operation, requiring specialized equipment or multiple people to disassemble the bulky battery pack, which increases labor costs and safety hazards. The weight of the battery is concentrated at the rear, and improper operation during manual disassembly can easily cause the center of gravity to become unbalanced, posing a risk of forklift tipping over or personnel being injured. Utility Model Content

[0004] In view of this, the present invention provides a battery clamping and releasing device and a forklift to solve the problems of low battery replacement efficiency and poor operation convenience of forklifts.

[0005] In a first aspect, this utility model provides a battery clamping and releasing device, comprising:

[0006] The support assembly includes a first support member, a second support member, and a third support member;

[0007] A clamping assembly, slidably connected to a support assembly, includes a first clamping part and a second clamping part, a first support member and a second support member respectively providing support for the first clamping part and the second clamping part, and the first clamping part and the second clamping part sliding relative to the first support member and the second support member respectively;

[0008] The drive assembly is partially connected to the third support member, and the first clamping part and the second clamping part achieve relative movement through the drive assembly.

[0009] Beneficial Effects: The coordinated use of the support assembly, clamping assembly, and drive assembly achieves stable clamping and rapid release of the battery. The support assembly employs a three-part design, including a first support member, a second support member, and a third support member, providing a robust mechanical foundation for the entire device and ensuring structural integrity while bearing the weight of the battery and operational vibrations. The clamping assembly and support assembly use a sliding connection, ensuring smooth clamping action and reducing frictional losses during movement. The drive assembly, linked to the clamping assembly via the third support member, enables relative movement between the first and second clamping parts, thereby completing the clamping or releasing operation of the battery. This not only improves the reliability of the device but also facilitates adjustment and maintenance according to different battery sizes, significantly enhancing the applicability and service life of the equipment.

[0010] In one optional embodiment, the first clamping part includes a first sliding part, a second sliding part, and a first clamping plate. The first sliding part and the second sliding part are both slidably disposed with the first support member. The first clamping plate is disposed between the first sliding part and the second sliding part and is fastened to the first sliding part and the second sliding part. The first sliding part and the second sliding part are staggered along a first direction.

[0011] Beneficial Effects: The first clamping part improves the clamping performance and stability of the device. By decomposing the first clamping part into a combination structure of a first sliding part, a second sliding part, and a first clamping plate, and implementing dual sliding point support on the first support member, the clamping force is effectively distributed, avoiding deformation caused by excessive force at a single point. The staggered arrangement of the first and second sliding parts along the first direction not only optimizes the spatial layout but also makes the distribution of clamping force more uniform. The first clamping plate is placed between the two sliding parts and is fastened to form a rigid clamping frame, greatly enhancing the stability of the clamping. This structure is particularly suitable for clamping heavy battery packs, effectively preventing loosening during handling or vibration. At the same time, the split design facilitates later maintenance; when a component wears out, only the corresponding part needs to be replaced, reducing maintenance costs.

[0012] In one optional embodiment, the second clamping part includes a third sliding part, a fourth sliding part, and a second clamping plate. The third sliding part and the fourth sliding part are both slidably disposed with the second support member. The second clamping plate is disposed between the third sliding part and the fourth sliding part and is fastened to the third sliding part and the fourth sliding part. The third sliding part and the fourth sliding part are staggered along the first direction. The second sliding part and the fourth sliding part achieve relative movement through a partial driving component.

[0013] Beneficial effects: The second clamping part is symmetrically arranged with the first clamping part. Through the combination of the third sliding part, the fourth sliding part, and the second clamping plate, it forms a bidirectional clamping structure with the first clamping part. This ensures that the battery is subjected to uniform force during clamping, avoiding battery deformation or damage caused by unilateral force. The third and fourth sliding parts also adopt a staggered arrangement, which not only optimizes space utilization but also ensures that the movement trajectories of the two clamping parts do not interfere with each other. The second and fourth sliding parts are linked by a drive component, ensuring the synchronicity of the clamping action and allowing both clamping plates to contact the battery surface simultaneously, achieving precise centering clamping.

[0014] In one optional embodiment, the drive assembly includes a first driven part, a second driven part, and a drive part. The first driven part and the second driven part are coaxially disposed on the third support member. The first driven part cooperates with both the second sliding part and the fourth sliding part. The drive part drives the second driven part, and the second driven part transmits driving force to the first driven part, thereby driving the second sliding part and the fourth sliding part.

[0015] Beneficial effects: The first and second driven parts are coaxially mounted on the third support member, which not only saves installation space but also improves the coaxiality of the transmission and reduces energy loss. The design of the first driven part cooperating with the second and fourth sliding parts allows for the simultaneous control of two moving parts by a single drive source, simplifying the structure while ensuring the synchronization of actions.

[0016] In one alternative embodiment, the drive assembly further includes a rack, which is disposed on the side of the second sliding portion and the fourth sliding portion near the first driven portion, and cooperates with the first driven portion for transmission.

[0017] Beneficial effects: The rack and pinion structure, located on the side of the second and fourth sliding parts near the first driven part, directly converts rotary motion into linear motion, resulting in high transmission efficiency and fast response. It avoids the backlash issues that may exist with traditional linkage mechanisms. The rack and pinion transmission has strong load-bearing capacity, making it suitable for applications requiring sustained clamping force. The rack is made of high-strength material, offering excellent wear resistance and a long service life. The clamping structure has a self-locking characteristic, maintaining the clamping state even in the event of a power outage, thus improving equipment safety. Maintenance is simple, requiring only periodic lubrication of the rack and pinions, resulting in low operating costs.

[0018] In one optional embodiment, the drive assembly further includes a drive shaft, a fixing part, and a drive motor. One end of the drive shaft is connected to the drive part, and the other end is connected to the drive motor. The drive shaft passes through the third support member and the fixing part in sequence, and the fixing part is adapted to be connected and fixed to an external structure.

[0019] Beneficial Effects: The integration of the drive shaft, mounting unit, and drive motor constitutes a complete power transmission system. The design, with one end of the drive shaft connected to the drive unit and the other end to the drive motor, allows for remote placement of the power source, enabling flexible motor positioning according to actual needs. The drive shaft's connection through the third support and mounting unit not only improves overall rigidity but also facilitates concentricity adjustment, ensuring smooth transmission. The connection design between the mounting unit and the external structure enhances the stability of the entire device, effectively suppressing vibration during operation. When a servo motor or stepper motor is used, precise control of the clamping position can be achieved, meeting the needs of automated production. This design also offers excellent scalability; the motor model can be changed according to different power requirements, or the output torque can be adjusted by adding a reducer to adapt to the clamping requirements of different battery specifications.

[0020] In one alternative implementation, the drive assembly further includes a manual wheel, which is coaxially arranged with the first driven part.

[0021] Beneficial effects: The manual wheel is coaxially mounted with the first driven unit, serving as an emergency operation method in case of power failure or maintenance. When the automatic system malfunctions, the operator can directly drive the first driven unit via the manual wheel to perform battery clamping or releasing operations, ensuring that the equipment is not completely paralyzed due to electrical failure.

[0022] In one alternative embodiment, a support plate is provided at the bottom of the first clamping plate to provide support. The first clamping plate and the second clamping plate have the same structure, and the support plate is provided inside the first clamping plate and the second clamping plate.

[0023] Beneficial effects: The support plate structure at the bottom of the first clamping plate enhances the device's support capacity and safety. The design of the support plate located inside the clamping plate provides additional bottom support when holding the battery, effectively distributing the battery weight and preventing excessive concentration of clamping force that could deform the battery casing. The first and second clamping plates use the same structural design, simplifying manufacturing and assembly processes and reducing production costs.

[0024] Secondly, this utility model also provides a forklift, comprising:

[0025] The forklift body; and the battery clamping and releasing device as described above, which is mounted on the forklift body and is adapted to clamp or release the battery.

[0026] Since the forklift includes the battery clamping and release device and the forklift itself, it has the same effect as the battery clamping and release device and the forklift, so it will not be described in detail here. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0040] Forklifts equipped with clip-on batteries solve the problem of low battery swapping efficiency in traditional electric forklifts through modular design. Utilizing standardized battery packs and a sliding rail mounting structure, the battery is mechanically locked to the rear or side of the forklift. A single operator can perform battery swapping, eliminating the need for lifting equipment or multiple people, significantly reducing swapping time to minutes. This makes them suitable for high-intensity operations such as logistics and warehousing. Furthermore, the clip-on design supports centralized battery charging and management, extending battery life and avoiding site limitations and safety risks associated with on-site charging. The compact battery layout optimizes the vehicle's center of gravity distribution, and combined with its environmentally friendly zero-emission characteristics, it becomes an ideal alternative to internal combustion forklifts.

[0041] Traditional forklift battery replacement typically requires removing bolts or connectors, relying on forklifts or lifting equipment to move heavy battery packs. This process is cumbersome and poses safety hazards. Batteries with concentrated weight at the rear can easily shift the forklift's center of gravity forward during removal, potentially causing tipping if not securely fastened. Manual handling also carries the risk of injury from falling batteries. The back-clamp design, through guide rails and a mechanical locking mechanism, achieves rapid battery positioning and secure installation, eliminating the center of gravity shift problem during removal and reducing the intensity of manual operation.

[0042] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0043] According to an embodiment of the present invention, a battery clamping and releasing device is provided, comprising:

[0044] Support assembly 1 includes a first support member 11, a second support member 12, and a third support member 13; clamping assembly 2 is slidably connected to support assembly 1 and includes a first clamping part 21 and a second clamping part 22, the first support member 11 and the second support member 12 provide support for the first clamping part 21 and the second clamping part 22 respectively, and the first clamping part 21 and the second clamping part 22 slide relative to the first support member 11 and the second support member 12 respectively; driving assembly 4 is partially connected to the third support member 13, and the first clamping part 21 and the second clamping part 22 achieve relative movement through driving assembly 4.

[0045] The stable clamping and rapid release of the battery are achieved through the cooperation of support component 1, clamping component 2, and drive component 4. Support component 1 adopts a three-part design, including a first support member 11, a second support member 12, and a third support member 13, providing a solid mechanical foundation for the entire device and ensuring structural integrity while bearing the weight of the battery and operational vibrations. Clamping component 2 is slidably connected to support component 1, ensuring smooth clamping action and reducing frictional losses during movement. Drive component 4 is linked to clamping component 2 via the third support member 13, enabling relative movement between the first clamping part 21 and the second clamping part 22, thereby completing the clamping or releasing operation of the battery. This not only improves the reliability of the device but also facilitates adjustment and maintenance according to different battery sizes, greatly enhancing the applicability and service life of the equipment.

[0046] Specifically, the first support member 11, the second support member 12 and the third support member 13 are fixed to the forklift and are long strip-shaped guide rail structures.

[0047] In some embodiments, combined with Figure 3 As shown, the first clamping part 21 includes a first sliding part 211, a second sliding part 212 and a first clamping plate 213. The first sliding part 211 and the second sliding part 212 are both slidably disposed with the first support member 11. The first clamping plate 213 is disposed between the first sliding part 211 and the second sliding part 212 and is fastened to the first sliding part 211 and the second sliding part 212. The first sliding part 211 and the second sliding part 212 are staggered along the first direction.

[0048] The first clamping part 21 improves the clamping performance and stability of the device. By decomposing the first clamping part 21 into a combined structure of a first sliding part 211, a second sliding part 212, and a first clamping plate 213, and implementing dual sliding point support on the first support member 11, the clamping force is effectively dispersed, avoiding deformation caused by excessive force at a single point. The staggered arrangement of the first sliding part 211 and the second sliding part 212 along the first direction not only optimizes the spatial layout but also makes the distribution of clamping force more uniform. The first clamping plate 213 is located between the two sliding parts and is fastened to form a rigid clamping frame, greatly enhancing the stability of the clamping. This structure is particularly suitable for clamping heavy battery packs and can effectively prevent loosening during handling or vibration. At the same time, the split design also facilitates later maintenance; when a component wears out, only the corresponding part needs to be replaced, reducing maintenance costs.

[0049] It is worth noting that the first clamping plate 213 has a support plate at its bottom, which is suitable for supporting the battery. The first clamping plate 213 and the second clamping plate 223 have the same structure, with the support plate located inside the first clamping plate 213 and the second clamping plate 223. The support plate structure at the bottom of the first clamping plate 213 improves the support capacity and safety of the device. The design of the support plate located inside the clamping plate can provide additional bottom support when clamping the battery, effectively distributing the battery weight and preventing excessive concentration of clamping force that could deform the battery casing. The identical structure of the first clamping plate 213 and the second clamping plate 223 simplifies the manufacturing and assembly process and reduces production costs.

[0050] In some embodiments, combined with Figure 3 As shown, the second clamping part 22 includes a third sliding part 221, a fourth sliding part 222, and a second clamping plate 223. The third sliding part 221 and the fourth sliding part 222 are both slidably disposed with the second support member 12. The second clamping plate 223 is disposed between the third sliding part 221 and the fourth sliding part 222 and is fastened to the third sliding part 221 and the fourth sliding part 222. The third sliding part 221 and the fourth sliding part 222 are staggered along the first direction. The second sliding part 212 and the fourth sliding part 222 achieve relative movement through a partial drive assembly 4.

[0051] The second clamping part 22 is symmetrically arranged with the first clamping part 21. Through the combination structure of the third sliding part 221, the fourth sliding part 222, and the second clamping plate 223, it together with the first clamping part 21 forms a bidirectional clamping structure. This ensures that the battery is subjected to uniform force during clamping, avoiding battery deformation or damage caused by force on one side. The third sliding part 221 and the fourth sliding part 222 also adopt a staggered arrangement, which not only optimizes space utilization but also ensures that the movement trajectories of the two clamping parts do not interfere with each other. The second sliding part 212 and the fourth sliding part 222 are linked through the drive component 4, ensuring the synchronicity of the clamping action and enabling the clamping plates on both sides to contact the battery surface simultaneously, achieving precise centering clamping.

[0052] In some embodiments, combined with Figure 2 and Figure 4 As shown, the drive assembly 4 includes a first driven part 41, a second driven part 42, and a drive part 44. The first driven part 41 and the second driven part 42 are coaxially disposed on the third support member 13. The first driven part 41 cooperates with the second sliding part 212 and the fourth sliding part 222. The drive part 44 drives the second driven part 42, and the second driven part 42 transmits the driving force to the first driven part 41, thereby driving the second sliding part 212 and the fourth sliding part 222.

[0053] The first driven part 41 and the second driven part 42 are coaxially arranged on the third support member 13, which not only saves installation space but also improves the coaxiality of the transmission and reduces energy loss. The design of the first driven part 41 cooperating with the second sliding part 212 and the fourth sliding part 222 allows two moving parts to be controlled by a single drive source, which simplifies the structure and ensures the synchronization of the actions.

[0054] Specifically, the first driven part 41 is a gear, the second driven part 42 is a pulley, and the driving part 44 is a pulley. The second driven part 42 and the driving part 44 are driven by a conveyor belt.

[0055] Furthermore, the drive assembly 4 also includes a rack 48, which is respectively disposed on the side of the second sliding part 212 and the fourth sliding part 222 near the first driven part 41, and cooperates with the first driven part 41 for transmission. The structure of disposing of the rack 48 on the side of the second sliding part 212 and the fourth sliding part 222 near the first driven part 41 directly converts rotational motion into linear motion, resulting in high transmission efficiency and fast response. It avoids the backlash problems that may exist with traditional linkage mechanisms. The rack and pinion 48 transmission has strong load-bearing capacity and is suitable for applications requiring long-term clamping force. The rack 48 is made of high-strength material, has good wear resistance, and a long service life. The clamping structure has a self-locking characteristic, maintaining the clamping state even in the event of a power outage, improving the safety of the equipment. Maintenance only requires periodic lubrication of the rack 48 and gears, making maintenance simple and operating costs low.

[0056] Furthermore, the drive assembly 4 also includes a drive shaft 45, a fixing part 46, and a drive motor 47. One end of the drive shaft 45 is connected to the drive part 44, and the other end is connected to the drive motor 47. The drive shaft 45 is sequentially disposed through the third support member 13 and the fixing part 46. The fixing part 46 is adapted to be connected and fixed to an external structure.

[0057] The integration of drive shaft 45, fixing part 46, and drive motor 47 constitutes a complete power transmission system. The design of drive shaft 45, with one end connected to drive part 44 and the other end connected to drive motor 47, allows for remote placement of the power source, enabling flexible arrangement of the motor position according to actual needs. The drive shaft 45 passes through the third support member 13 and fixing part 46, improving overall rigidity and facilitating concentricity adjustment to ensure smooth transmission. The connection design between fixing part 46 and the external structure enhances the stability of the entire device and effectively suppresses vibration during operation. When drive motor 47 is a servo motor or stepper motor, precise control of the clamping position can be achieved, meeting the needs of automated production. This design also has excellent scalability; the motor model can be changed according to different power requirements, or the output torque can be adjusted by adding a reducer to adapt to the clamping requirements of different battery specifications.

[0058] Furthermore, the drive assembly 4 also includes a manual wheel 43, which is coaxially arranged with the first driven part 41. The coaxial arrangement of the manual wheel 43 and the first driven part 41 serves as an emergency operation method in case of power failure or maintenance. When the automatic system malfunctions, the operator can directly drive the first driven part 41 via the manual wheel 43 to perform battery clamping or releasing operations, ensuring that the equipment is not completely paralyzed due to electrical faults.

[0059] As one feasible implementation, the pulley and gear transmission in the original drive assembly 4 are replaced with a hydraulic system, including a hydraulic cylinder, a hydraulic pump, and control valves. The first driven part 41 and the second driven part 42 are replaced with hydraulic cylinder piston rods, directly connected to the second sliding part 212 and the fourth sliding part 222. The drive part 44 is replaced with a hydraulic pump, transmitting power through hydraulic lines. The hydraulic system provides greater output force and smoother movement, suitable for heavy-duty battery clamping. The self-locking characteristic of the hydraulic cylinder ensures stable clamping without the need for continuous power supply. The system has strong vibration resistance, suitable for harsh working conditions.

[0060] According to an embodiment of the present invention, another aspect provides a forklift, comprising:

[0061] Forklift body 5; and

[0062] As described above, the battery clamping and releasing device is installed on the forklift body 5 and is suitable for clamping or releasing the battery.

[0063] The specific workflow is as follows:

[0064] Battery clamping: The drive motor 47 transmits power to the drive unit 44 via the drive shaft 45, which drives the second driven unit 42 to rotate. The second driven unit 42 transmits power synchronously to the first driven unit 41 via coaxial transmission, ensuring synchronous movement on both sides. The first driven unit 41 meshes with the rack 48 on the second sliding part 212 and the fourth sliding part 222, converting the rotational motion into linear motion: the second sliding part 212 slides along the first support member 11; the fourth sliding part 222 slides along the second support member 12. Due to the staggered design of the sliding parts, they do not interfere with each other during movement, and the double sliding point support ensures stability. The first clamping plate 213 and the second clamping plate 223 move towards the battery synchronously; the support plate on the inner side of the clamping plate contacts the bottom of the battery, providing support force, while the sides of the clamping plate clamp the two sides of the battery, forming a three-point stable clamping. The gear and rack transmission has a self-locking characteristic, and the clamping state can be maintained even if the power is cut off after the clamping is in place; the drive motor 47 stops running, completing the clamping.

[0065] Battery release: The drive motor 47 reverses direction, transmitting reverse torque to the first driven part 41 via the drive shaft 45 and the second driven part 42; the first driven part 41 drives the rack 48 to move outward, causing the second sliding part 212 and the fourth sliding part 222 to slide in opposite directions. The first clamping plate 213 and the second clamping plate 223 move away from the battery synchronously, the support plate disengages from the bottom of the battery, and the clamping force is completely released; the clamping assembly 2 retracts to the initial position, preparing for the next clamping. In case of power failure, the first driven part 41 can be directly rotated via the manual wheel 43, and the rack 48 can be manually driven to complete the release or clamping.

[0066] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
