Description

Technical Field

[0001] This invention relates to the field of battery pack processing, and more specifically to a multi-cell battery pack equidistant clamping and mounting mechanism. Background Technology

[0002] A battery pack is an energy storage device that combines multiple batteries in series or parallel. It is widely used in new energy vehicles, energy storage systems, industrial equipment and other fields. In the production and assembly process of battery packs, it is usually necessary to bind and fix several battery cells with fixing rings to improve the structural integrity and connection reliability of the battery pack. Currently, during the installation of battery pack retaining rings, due to manufacturing errors in individual battery cells and slight expansion before assembly, the inner diameter of the retaining ring is usually smaller than the outer diameter of the battery pack. Therefore, the battery pack needs to be clamped before the retaining ring is inserted. However, in most existing clamping devices, the force at both ends of the battery pack cannot be released in time after clamping, making it difficult to smoothly insert the retaining ring, resulting in a difficult and inefficient installation operation. Furthermore, existing devices lack centering and positioning functions during clamping, making the battery module prone to misalignment and affecting installation accuracy. In addition, to achieve different functions, some existing installation mechanisms often use multiple independent drive sources and rely on complex electrical control systems for timing control. This not only increases the structural complexity and manufacturing cost of the equipment but also places high demands on the reliability of the control system. If control malfunctions or sensor failures occur, interference or coordination errors can easily occur between the various mechanisms.

[0003] Therefore, it is necessary to invent a multi-cell battery pack equidistant clamping and mounting mechanism. Summary of the Invention

[0004] To address this issue, the present invention provides an equidistant clamping and mounting mechanism for multi-cell battery packs, thereby resolving the problems described in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-cell battery pack equidistant clamping and mounting mechanism, comprising a base plate and bases fixedly mounted on both sides of the top of the base plate. A battery module is installed at the middle position of the top of the base plate. A vertically lifting connecting seat is installed inside each of the two bases. A horizontally retractable clamping plate is embedded inside the connecting seat. A top plate is fixedly connected between the two bases. A partition is fixedly connected between the two connecting seats. A servo electric cylinder is fixedly connected to the top of the top plate. The piston rod of the servo electric cylinder passes through the top plate and is fixedly connected to the partition, for driving the connecting seats to move up and down. A clamping assembly is provided at the bottom of the base. A driving assembly is provided at the top of the clamping assembly. The driving assembly is driven to the clamping assembly and the connecting seats. When the connecting seats move up and down, the driving assembly drives the clamping assembly to perform clamping or releasing operations.

[0006] Preferably, a spring a is fixedly connected to the end of the clamping plate away from the battery module, the end of the spring a is fixedly connected to the inner wall of the connecting seat, a limit plate is fixedly connected to the top of the clamping plate, and a limit unit is provided on the top of the clamping plate.

[0007] Preferably, the limiting unit includes a spring b fixedly installed inside the clamping plate, a buckle fixedly connected to the top of the spring b, the top of the buckle extending to the top of the clamping plate, the top of the buckle being hemispherical, the inner wall of the top of the connecting seat being provided with a first groove and a second groove corresponding to the limiting unit, and a pressure rod fixedly connected to the inner wall of the top of the base, the pressure rod being correspondingly located at the top of the second groove, and when the connecting seat rises to the top position, the pressure rod extends into the second groove and abuts against the buckle.

[0008] Preferably, the clamping assembly includes main clamps located on both sides of the top of the base plate, with a slide rail fixedly connected to the bottom of each main clamp and the slide rail slidably embedded in the top of the base plate. Each of the two main clamps has a secondary clamp that is slidably connected to it on the opposite side, and a spring c is fixedly connected between the main clamp and the secondary clamp.

[0009] Preferably, a rubber pad is fixedly connected to the side of the sub-clamp near the battery module.

[0010] Preferably, the drive assembly includes a protrusion fixedly connected to the opposite sides of two connecting seats, a vertical shaft is provided through the protrusion, a spiral groove is provided on the outer side of the vertical shaft, a slider adapted to and slidably connected to the spiral groove is fixedly connected inside the protrusion, a gear is fixedly connected to the bottom end of the vertical shaft, and the drive assembly also includes a toothed plate fixedly connected to the top of the main clamp, the toothed plate being meshed with the gear.

[0011] Preferably, the bottom of the clamping plate is provided with a guide groove with an inclined inner wall at the top, and a guide block is fixedly connected inside the base. The guide block is correspondingly arranged at the bottom of the two guide grooves, and the top of the guide block slides and adapts to the inclined surface of the guide groove.

[0012] Preferably, the front side of the clamping plate is provided with a chamfer.

[0013] The beneficial effects of this invention are: This invention achieves the coordinated completion of multiple processes, including fixed ring clamping, vertical pressing, battery module centering and clamping, and automatic release of the fixed ring, through the linkage between the connecting seat, clamping plate, clamping assembly and driving assembly, with the servo electric cylinder as the sole active power source. In the entire work cycle, the servo electric cylinder only needs to perform one extension and retraction action to complete all processes in sequence. The timing and stroke of all actions are precisely guaranteed by the mechanical geometry of each component, without relying on the timing programming or position feedback of the electrical control system. This significantly reduces the complexity and failure rate of the control system and effectively improves the automation level and production efficiency of battery pack fixed ring installation. This invention, through the coordinated design of the protrusions, vertical shaft, spiral groove, slider, gears, and toothed plates in the drive assembly, precisely transforms the lifting linear motion of the connecting seat into the horizontal linear motion of the main clamping seat. The displacement of the two main clamping seats is driven by the same pair of gears and racks with the same tooth module, ensuring that the clamping components on both sides always maintain equidistant symmetrical movement, guaranteeing the precise centering and positioning of the battery module in the width direction. At the same time, through the flexible force transmission design of the spring c between the main clamping seat and the auxiliary clamping seat, the clamping force increases linearly with the increase of spring compression, realizing flexible and gradual clamping of the battery module, avoiding damage to the battery module caused by rigid impacts, and is suitable for the installation requirements of battery modules of different widths, with good dimensional adaptability and versatility. This invention utilizes the sliding engagement between the guide groove at the bottom of the connecting seat and the guide block inside the base to automatically trigger the release of the clamping plate and the fixing ring when the connecting seat moves to the bottom. This achieves automatic release of the fixing ring without the need for an additional power source or control signal. Through the switching engagement of the buckle and slot 1 and slot 2 in the limiting unit, as well as the automatic pressing and unlocking of the pressure rod, the clamping plate automatically switches and resets between the clamping and releasing states. In the entire work cycle, the operator only needs to complete the initial installation of the fixing ring; all other processes are completed automatically by the mechanism, significantly reducing the operator's labor intensity and improving the consistency and quality of fixing ring installation.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] See attached document Figure 1 - Appendix Figure 7This invention provides a multi-cell battery pack equidistant clamping and mounting mechanism, including a base plate 1 and bases 2 fixedly mounted on both sides of the top of the base plate 1. A battery module 3 is installed at the middle position of the top of the base plate 1. Each of the two bases 2 has a vertically adjustable connecting seat 4 installed inside. The connecting seat 4 has a horizontally extendable clamping plate 5 embedded inside. A top plate 6 is fixedly connected between the two bases 2. A partition 7 is fixedly connected between the two connecting seats 4. A servo electric cylinder 8 is fixedly connected to the top of the top plate 6. The piston rod of the servo electric cylinder 8 passes through the top plate 6 and is fixedly connected to the partition 7, and is used to drive the connecting seat 4 to move up and down. A clamping assembly is provided at the bottom of the base 2. A driving assembly is provided at the top of the clamping assembly. The driving assembly is driven to the clamping assembly and the connecting seat 4. When the connecting seat 4 moves up and down, the driving assembly drives the clamping assembly to perform clamping or loosening operations.

[0020] To ensure the smooth lifting and lowering of the connecting seat 4, the device employs the following technical solution: each of the four corners of the connecting seat 4 is equipped with a limiting slide rod that is slidably connected to it, and the limiting slide rod is fixedly connected to the base 2.

[0021] To achieve the elastic clamping of the clamping plate 5 onto the fixing ring and its automatic reset after clamping, the device employs the following technical solution: a spring a9 is fixedly connected to the end of the clamping plate 5 away from the battery module 3, the end of the spring a9 is fixedly connected to the inner wall of the connecting seat 4, a limiting plate 10 is fixedly connected to the top of the clamping plate 5, and a limiting unit is provided on the top of the clamping plate 5; through the elastic force of the spring a9, the clamping plate 5 can remain extended in its natural state, facilitating the insertion of the fixing ring; when subjected to external pressure, it can retract and automatically reset after the external force disappears, ensuring the reliability and continuity of the clamping action.

[0022] To achieve stable limiting and state switching of the clamping plate 5 under different working states, this device adopts the following technical solution: The limiting unit includes a spring b11 fixedly installed inside the clamping plate 5. A buckle 12 is fixedly connected to the top of the spring b11, and the top of the buckle 12 extends to the top of the clamping plate 5. The top of the buckle 12 is hemispherical. The inner wall of the top of the connecting seat 4 is provided with a first groove 401 and a second groove 402 corresponding to the limiting unit. A pressure rod 13 is fixedly connected to the inner wall of the top of the base 2. The pressure rod 13 is correspondingly set at the top of the second slot 402, and when the connecting seat 4 rises to the top position, the pressure rod 13 extends into the second slot 402 and abuts against the buckle 12; through the cooperation of the buckle 12 with the first slot 401 or the second slot 402, the clamping plate 5 can be locked in the extended or retracted state; and the abutting design of the pressure rod 13 and the buckle 12 can automatically release the lock when the connecting seat 4 is reset, realizing the automatic switching of the state of the clamping plate 5 without additional control, improving the automation level and operating efficiency of the mechanism.

[0023] To achieve automatic centering and simultaneous clamping on both sides of the battery module 3 during the installation of the fixing ring, the device employs the following technical solution: The clamping assembly includes main clamping seats 14 located on both sides of the top of the base plate 1. A slide rail 16 is fixedly connected to the bottom of the main clamping seat 14, and the slide rail 16 is slidably embedded in the top of the base plate 1. A secondary clamping seat 15 is slidably connected to the two main clamping seats 14 on their opposing sides. A spring c17 is fixedly connected between the main clamping seats 14 and the secondary clamping seats 15. The main clamping seat 14 serves as a power transmission component, and the secondary clamping seat 15 serves as a direct contact component. The two are slidably engaged and the clamping force is transmitted by the spring c17. This ensures the synchronicity of the clamping action on both sides and provides a flexible and gradually increasing clamping force through the compression of the spring, avoiding rigid impact damage to the battery module 3.

[0024] To avoid surface scratches or damage from hard contact between the clamping components and the battery module 3, the device employs the following technical solution: a rubber pad 18 is fixedly connected to the side of the auxiliary clamp 15 near the battery module 3; the rubber pad 18 has good elasticity and a large coefficient of friction, which can effectively protect the outer shell of the battery module 3 and enhance clamping stability, preventing the battery module 3 from shifting during installation.

[0025] To achieve the power conversion and transmission between the lifting linear motion of the connecting seat 4 and the horizontal linear motion of the main clamping seat 14, this device adopts the following technical solution: The drive assembly includes protrusions 19 fixedly connected to the opposite sides of the two connecting seats 4. A vertical shaft 20 is provided through the protrusions 19. A spiral groove 2001 is opened on the outer side of the vertical shaft 20. A slider 1901 adapted to and slidably connected to the spiral groove 2001 is fixedly connected inside the protrusions 19. A gear 21 is fixedly connected to the bottom end of the vertical shaft 20. The drive assembly also includes a toothed plate 22 fixedly connected to the top of the main clamping seat 14. The toothed plate 22 is meshed with the gear 21. By sliding the slider 1901 in the spiral groove 2001, the lifting motion of the connecting seat 4 is converted into the rotational motion of the vertical shaft 20. Then, by meshing the gear 21 rack, the rotational motion is accurately converted into the horizontal linear motion of the main clamping seat 14. The transmission structure is compact and responsive. The two connecting seats 4 drive the clamping assemblies on both sides respectively, ensuring the independence and synchronization of the clamping action.

[0026] To achieve the goal of automatically triggering the release action of the clamping plate 5 on the fixing ring when the connecting seat 4 descends to the bottom, the device adopts the following technical solution: The bottom of the clamping plate 5 is provided with a guide groove 501 with an inclined inner wall at the top. A guide block 23 is fixedly connected inside the base 2. The guide block 23 is correspondingly set at the bottom of the two guide grooves 501, and the top of the guide block 23 slides and adapts to the inclined surface of the guide groove 501. When the connecting seat 4 descends to the preset position, the top of the guide block 23 slides and contacts the inclined surface of the guide groove 501, generating a horizontal component force, thereby pushing the clamping plates 5 on both sides of the connecting seat 4 to move, so that the buckle 12 disengages from the first buckle slot 401 and enters the second buckle slot 402, realizing the automatic release of the fixing ring.

[0027] To facilitate the initial installation of the fixing ring, which is smoothly inserted between the two clamping plates 5, the device employs the following technical solution: a chamfer is provided on the front side of the clamping plate 5; the chamfer structure makes the opening at the front end of the clamping plate 5 funnel-shaped, which guides the insertion of the fixing ring, reduces the installation difficulty, and improves the operating efficiency.

[0028] The process of using this invention is as follows: During the ring assembly preparation stage, the piston rod of the servo electric cylinder 8 is in the extended state, the connecting seat 4 is in the highest position, and the clamping plate 5 extends outward under the elastic force of the spring a9. The distance between the two clamping plates 5 is less than the outer diameter of the fixed ring. The operator pushes the fixed ring into the space between the two clamping plates 5 along the chamfer on the front side of the clamping plate 5. The edge of the fixed ring pushes the clamping plate 5 to retract into the connecting seat 4 against the elastic force of the spring a9. When the fixed ring is fully inserted, the buckle 12 inside the clamping plate 5 springs up under the elastic force of the spring b11 and is inserted into the slot 401 on the inner wall of the top of the connecting seat 4, thereby locking the clamping plate 5 in the retracted state. At this time, the clamping plate 5 forms a stable clamping force on the fixed ring. The fixed ring is suspended and positioned directly above the battery module 3, and the limiting plate 10 on the top of the clamping plate 5 is located above the upper end face of the fixed ring, providing a force application surface for subsequent downward pressing. Then, the downward pressing stage begins. After the servo electric cylinder 8 is started, its piston rod extends, pushing the connecting seat 4 to move vertically downward along the base 2. Since the clamping plate 5 is locked by the slot 401, the clamping plate 5 and the connecting seat 4 remain relatively fixed. The fixing ring moves down synchronously with the connecting seat 4 and is gradually fitted into the outer wall of the battery module 3 under the push of the limiting plate 10 until it reaches the designated installation position on the outer wall of the battery module 3. During this process, the limiting plate 10 always presses against the upper end face of the fixing ring to ensure that the fixing ring does not tilt or shift during the descent. The second driving effect is the horizontal clamping of the clamping assembly. When the connecting seat 4 moves down, its laterally fixed protrusion 19 drives the slider 1901 to move down synchronously. The slider 1901 slides along the spiral groove 2001 on the outside of the vertical shaft 20. Due to the guiding effect of the spiral groove 2001, the vertical linear movement of the slider 1901 forces the vertical shaft 20 to move downward. Shaft 20 generates rotational motion around its own axis, and gear 21 at the bottom of vertical shaft 20 rotates accordingly. Through meshing transmission with the toothed plate 22 at the top of main clamp 14, the rotational motion is converted into horizontal linear motion of main clamp 14. Both main clamps 14 move synchronously towards battery module 3 under the drive of gear 21 rack, driving secondary clamp 15 to gradually approach the sides of battery module 3. Rubber pads 18 on secondary clamp 15 first contact the outer shell of battery module 3. After that, main clamp 14 continues to move towards battery module 3, spring c17 is compressed, and clamping force increases linearly with the increase of spring compression, realizing flexible and gradual clamping of battery module 3. Since the displacement of both main clamps 14 is driven by the same pair of gear 21 racks and the number of teeth and the module are the same, the clamping components on both sides always maintain equidistant symmetrical movement, ensuring the centering and positioning of battery module 3 in the width direction. When the connector 4 is lowered to its lowest position, the retaining ring fits precisely into the designated installation position of the battery module 3, as shown in the attached diagram. Figure 8As shown, at this point, the bottom release stage begins. The inclined surface of the guide groove 501 at the bottom of the connecting seat 4 slides into contact with the top of the guide block 23 fixed inside the base 2. The guide block 23 remains stationary, and the connecting seat 4 continues to bear the downward pulling force of the servo electric cylinder 8. The top of the guide block 23 slides relative to the inclined surface of the guide groove 501, thereby generating a horizontal component force. This horizontal component force pushes the clamping plate 5 to overcome the elastic force of the spring a9 and continue to retract into the connecting seat 4. During the retraction of the clamping plate 5, the hemispherical top of the buckle 12 interferes with the edge of the slot 401, forcing the buckle 12 to overcome the elastic force of the spring b11 and retract downward into the clamping plate 5, thereby releasing the buckle 12 from the slot 401. As the clamping plate 5 continues to retract, the buckle 12 slides to the bottom of the second slot 402. Under the elastic force of the spring b11, it pops out again and locks into the second slot 402, locking the clamping plate 5 in the further retracted position. At this time, the inner end face of the clamping plate 5 has completely detached from the outer wall of the fixing ring. The fixing ring is no longer subject to the clamping force of the clamping plate 5 and is held in the installation position by the interference fit between itself and the outer wall of the battery module 3. The key to this stage is that the tilt angle of the guide groove 501, the height position of the guide block 23, and the distance between the first slot 401 and the second slot 402 are precisely matched and designed so that the two actions of the fixing ring being fully in place and the clamping plate 5 releasing the fixing ring are strictly synchronized in time. After the fixing ring is installed, the upward reset phase begins. The servo electric cylinder 8 reverses its movement, and the piston rod retracts, causing the connecting seat 4 to move upward. As the connecting seat 4 moves upward, the slider 1901 slides in the opposite direction along the spiral groove 2001, and the vertical shaft 20 rotates in the opposite direction. The gear 21 drives the toothed plate 22 and the main clamping seat 14 to move horizontally in the opposite direction. The clamping assembly gradually loosens its grip on the battery module 3, making room for the installation of the next set of battery modules 3. At the same time, the connecting seat 4 drives the clamping plate 5 and the buckle 12 fixed in the clamping plate 5 to move upward synchronously. When the connecting seat 4 rises to the highest position, it is fixedly connected to the base 2. The pressure rod 13 on the inner wall of the top passes through the slot 402 and abuts against the hemispherical top of the buckle 12. As the connecting seat 4 continues to be pushed upward by the servo electric cylinder 8, the pressure rod 13 remains stationary. The pressure rod 13 overcomes the elastic force of the spring b11 and presses the buckle 12 downward into the clamp 5, causing the buckle 12 to disengage from the slot 402. At this time, the clamp 5 is no longer subject to the locking constraint of any limiting unit. The compressed spring a9 rebounds and pushes the clamp 5 outward from the connecting seat 4, returning it to its initial extended state, preparing for the installation of the next fixing ring. Thus, a complete work cycle ends.

[0029] Throughout the entire work cycle, the servo electric cylinder 8 only needs to perform one extension and retraction action to sequentially complete all processes, including clamping the fixed ring, vertical pressing, centering and clamping the battery module 3, automatic release of the fixed ring, reset of the clamping components, and reset of the clamping plate 5. The timing and stroke of all actions are precisely guaranteed by the mechanical geometry of each component, without relying on the timing programming or position feedback of the electrical control system, which significantly reduces the complexity and failure rate of the control system.

[0030] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
