Description

Technical Field

[0001] This invention relates to the field of battery handling equipment technology, specifically a handling device for new energy vehicle batteries. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the demand for the production, installation and maintenance of batteries, which are the core power source of the vehicle, is increasing day by day. New energy vehicle batteries are usually characterized by large size, heavy weight and high value. Therefore, the handling operations between different scenarios such as production workshops, warehouses and maintenance stations must rely on professional handling equipment to improve efficiency and ensure safety.

[0003] Referring to Chinese utility model patent, publication number CN213459903U, entitled "A Handling Device for New Energy Vehicle Batteries," this device includes a handling device housing. A fixing pipe is fixedly connected to one side of the inner wall of the housing, and a light-shielding cloth is fixedly connected to the outer wall of the fixing pipe. A fixing ring is fixedly connected to one side of the light-shielding cloth, and a fixing hook is fixedly connected to the other side of the inner wall of the housing. This handling device for new energy vehicle batteries achieves the purpose of convenient storage and retrieval. New energy vehicle batteries can be directly stored and retrieved from the placement port using a crane. Workers can enter the handling device through the handling door to operate or perform statistics. The multiple storage and retrieval methods increase the usage scenarios, reduce usage costs, and meet the usage needs under different conditions.

[0004] However, some problems still exist in actual use: Existing devices for transporting new energy vehicle batteries are mostly simple transport vehicles that lack effective automatic adjustment and fixing functions. After the battery is placed, it is only secured by simple baffles or straps, which is not only time-consuming and labor-intensive, but also prone to collisions due to shaking during movement, posing safety hazards. On the other hand, existing devices often cannot adaptively adjust to different battery models or weights, resulting in poor versatility. Furthermore, the center of gravity of the entire device is too high when carrying heavy batteries, leading to insufficient stability during movement and a tendency to tip over, posing a serious threat to operators and the expensive battery itself. Summary of the Invention

[0005] Technical problems to be solved The purpose of this invention is to overcome the shortcomings of existing technologies. Most existing devices for transporting new energy vehicle batteries are simple transport vehicles that lack effective automatic adjustment and fixing functions. After the battery is placed, it is only fixed by simple baffles or straps, which is not only time-consuming and labor-intensive, but also prone to collisions due to shaking during movement, posing safety hazards. Secondly, existing devices often cannot adaptively adjust to different battery models or weights, resulting in poor versatility. Furthermore, the center of gravity of the entire device is too high when carrying heavy batteries, leading to insufficient stability during movement and a tendency to tip over, which poses a serious threat to operators and the expensive battery itself.

[0006] Technical solution To achieve the above objectives, the present invention provides the following technical solution: A handling device for new energy vehicle batteries includes a battery body and a base. Two sets of symmetrical casters are movably connected to the bottom of the base. A connecting seat, U-shaped, is fixedly connected to one end of the base. A pull rod is movably connected inside the connecting seat via a pivot, and handles are fixedly connected to both sides of the other end of the pull rod. A load-bearing adjustment mechanism is fixedly connected to the surface of the base, and a load-bearing plate is fixedly connected to the surface of the load-bearing adjustment mechanism. Rectangular grooves are formed at the four corners of the load-bearing plate. The battery body is placed on the surface of the load-bearing plate, and stabilizing mechanisms are correspondingly provided at the four corners of the load-bearing plate. The stabilizing mechanisms are used to abut and fix the corners of the battery body, and are linked to an auxiliary handling mechanism.

[0007] Furthermore, the load-bearing adjustment mechanism includes a drive motor, which is fixedly connected to the middle position of one side of the base. The output end of the drive motor is fixedly connected to a drive rod through a coupling, and the drive rod is movably connected to the surface of the base through a rotating shaft. A set of symmetrical positive and negative threads are formed on the surface of the drive rod.

[0008] The above technical solution utilizes a drive motor fixed on the base as the power input, and transmits the rotational power to the drive rod via a coupling. The symmetrical forward and reverse threads on the surface of the drive rod are the key design for achieving precise control. When the motor rotates forward and reverse, it drives the connected components to achieve synchronous, symmetrical and equidistant opposite or opposite movements, thus providing a reliable and efficient mechanical basis for the subsequent height adjustment and balanced lifting of the bearing plate.

[0009] Furthermore, the load-bearing adjustment mechanism also includes two cantilever arms, which are symmetrically arranged and connected to the outside of the drive rod via positive and negative threads at their middle positions. Adjustment wheels are movably connected to both ends of each cantilever arm.

[0010] By using the above technical solution, and by symmetrically installing two cantilever arms on the positive and negative threads of the drive rod, it is ensured that when the drive rod rotates, the two cantilever arms can move in opposite or opposite directions in a straight line synchronously, thereby ensuring the balance and stability of the lifting process.

[0011] Furthermore, a set of symmetrical contact strips are fixedly connected to the bottom of the bearing plate. The bottom of the contact strips is in the shape of an inverted U-shaped arc. The adjusting wheel is located directly below the two contact strips and is in close contact with the bottom of the contact strips. A set of symmetrical compression springs are fixedly connected to the protruding part of the bottom of the contact strips, and the bottom of the compression springs is fixedly connected to the surface of the base.

[0012] Through the above technical solution, the special inverted convex arc design at the bottom of the contact strip provides a precise movement trajectory for the rolling of the adjustment wheel, thereby transforming the horizontal movement of the cantilever into a smooth and controllable vertical lifting and lowering of the support plate. At the same time, the compression spring fixed below the protrusion of the contact strip is compressed when the support plate bears the weight of the battery. This not only plays a role in adaptive buffering and vibration absorption, protecting the battery from rigid impact, but also provides assistance for the reset of the support plate through its elastic restoring force, ensuring the smoothness and safety of the entire adjustment process.

[0013] Furthermore, the stabilizing mechanism includes a stabilizing bar, which is V-shaped and has a top plate fixedly connected to its top end. A connecting rod is fixedly connected to the rear end of the stabilizing bar, and transmission bars are fixedly connected to both ends of the connecting rod. The transmission bars are L-shaped, and the end of the transmission bar away from the connecting rod extends to the bottom of the bearing plate.

[0014] The above technical solution utilizes an L-shaped transmission bar that extends to the bottom of the support plate. When the support plate descends, it will drive the transmission bar to rotate, which in turn will pull the V-shaped stabilizing bar to swing through the connecting rod, causing the top plate at its top to automatically move closer to the corner of the battery.

[0015] Furthermore, an elastic rope is fixedly connected to the bottom of the stabilizing bar. The elastic rope is inclined and its bottom is fixedly connected to the surface of the base. A return spring is sleeved on the outside of the elastic rope, and the two ends of the return spring are fixedly connected to the bottom of the stabilizing bar and the surface of the base, respectively.

[0016] With the above technical solution, when the stabilizing bar swings to clamp the battery, the inclined elastic rope and return spring are stretched, thereby storing elastic potential energy. This energy is converted into a continuous pulling force on the top plate, ensuring that even during transportation bumps, the clamping structure can firmly lock the battery and prevent it from loosening or shifting. When it is necessary to unload the battery, as the carrier plate rises, the stabilizing bar automatically swings back to its original position under the strong restoring force of the elastic rope and return spring, thereby quickly releasing the clamping state. This realizes the automation of the entire clamping and releasing process, greatly improving the convenience and reliability of operation.

[0017] Furthermore, the auxiliary handling mechanism includes a support frame, the top of which is fitted with a collar and is fixedly connected to the bottom outer side of the stabilizing bar. The bottom of the support frame penetrates the base and extends to its bottom, and the connection between the support frame and the base is slidably connected.

[0018] Through the above technical solution, the vertical movement of the support frame can directly drive the stabilizing bar to rise and fall synchronously. At the same time, the support frame passes through the base and adopts a sliding connection, which provides precise vertical guidance and ensures the stability and smoothness of the lifting process.

[0019] Furthermore, a fixing block is fixedly connected to the bottom of the support frame, and an electric push rod is fixedly connected to the top of the fixing block. The electric push rod is fixedly connected to the bottom of the base, and an auxiliary wheel is movably connected to the bottom of the fixing block via a universal joint.

[0020] The above technical solution allows the auxiliary wheels to be stably lowered to the ground via the universal joint, forming a wider and more stable support chassis together with the original universal wheels to prevent tipping over, and also working together to lock or release the battery during the lifting process.

[0021] Compared with existing technologies, this type of handling device for new energy vehicle batteries has the following advantages: I. This invention uses a drive motor to drive a cantilever to move in opposite directions via a forward and reverse threaded drive rod, causing the adjusting wheel to roll along a special arc at the bottom of the contact bar. This not only automatically adjusts the height of the support plate according to the weight of the battery, but also provides effective cushioning and vibration absorption through the compression spring at the bottom. This prevents the battery from being damaged by rigid impacts during placement or movement, ensuring the smoothness and safety of the handling process. It achieves automated and precise adaptation and cushioning protection for the battery height.

[0022] Second, when the load-bearing plate moves downward due to the weight of the battery, the L-shaped transmission bar cleverly pushes the V-shaped stabilizing bar to swing, so that the top plate automatically and accurately fits the corners of the battery. At the same time, the compressed elastic rope and the return spring provide a continuous and stable holding force for the clamping action, forming a four-point locking. The battery can be firmly fixed without manual intervention, effectively preventing the risk of shaking, displacement or even falling during transportation, and greatly improving the reliability of handling.

[0023] Third, this invention uses an electric push rod to drive the support frame to descend, bringing the auxiliary wheels into contact with the ground. This, together with the original casters, forms a wider and more stable support chassis, effectively lowering the center of gravity of the device when moving or turning. This prevents the risk of tipping over due to excessive battery weight, making the entire handling process easier to control and ensuring the safety of both the operator and the battery. It further enhances the stability and safety of the device during movement. In addition, the auxiliary handling mechanism works in conjunction with the stabilizing mechanism, using the support frame to drive the stabilizing bar to press down synchronously, achieving final locking of the battery.

[0024] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1-8 As shown, the present invention provides a technical solution: a handling device for a new energy vehicle battery, including a battery body 1 and a base 2. Two sets of symmetrical casters 3 are movably connected to the bottom of the base 2. A connecting seat 4 is fixedly connected to one end of the base 2, and the connecting seat 4 is U-shaped. A pull rod 5 is movably connected to the inside of the connecting seat 4 through a rotating shaft, and handles 6 are fixedly connected to both sides of the other end of the pull rod 5. A load-bearing adjustment mechanism 7 is fixedly connected to the surface of the base 2. A load-bearing plate 10 is fixedly connected to the surface of the load-bearing adjustment mechanism 7, and rectangular grooves are opened at the four corners of the load-bearing plate 10. The battery body 1 is placed on the surface of the load-bearing plate 10. A stabilizing mechanism 8 is correspondingly provided at the four corners of the load-bearing plate 10. The stabilizing mechanism 8 is used to abut and fix the corners of the battery body 1. The stabilizing mechanism 8 is linked to the auxiliary handling mechanism 9.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the load-bearing adjustment mechanism 7 includes a drive motor 701, which is fixedly connected to the middle position of one side of the base 2. The output end of the drive motor 701 is fixedly connected to a drive rod 702 via a coupling, and the drive rod 702 is movably connected to the surface of the base 2 via a rotating shaft. A set of symmetrical positive and negative threads are formed on the surface of the drive rod 702. The load-bearing adjustment mechanism 7 also includes two cantilever arms 703, which are symmetrically arranged and movably connected to the outside of the drive rod 702 via positive and negative threads at their middle positions. Adjusting wheels 704 are movably connected to both ends of the cantilever arms 703. A set of symmetrical contact strips 705 are fixedly connected to the bottom of the load-bearing plate 10. The bottom of the contact strips 705 is an inverted U-shaped arc. The adjusting wheels 704 are located directly below the two contact strips 705 and are in close contact with the bottom of the contact strips 705. A set of symmetrical compression springs 706 are fixedly connected to the protruding position at the bottom of the contact strips 705, and the bottom of the compression springs 706 is fixedly connected to the surface of the base 2.

[0030] The drive motor 701 drives the drive rod 702 with positive and negative threads to rotate, thereby driving the two cantilever arms 703 to move synchronously in opposite directions or in opposite directions. The adjusting wheel 704 on the cantilever arm 703 rolls along the special inverted U-shaped contact strip 705 at the bottom of the support plate 10, which can precisely control the lifting height of the support plate 10. At the same time, the compression spring 706 at the bottom of the contact strip 705 is compressed under the weight of the battery, which not only realizes adaptive height fine adjustment according to the weight of the battery, but also provides a key buffering and vibration absorption function, effectively avoiding damage to the battery due to rigid impact during placement or movement, and ensuring the stability and safety of the entire handling process.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the stabilizing mechanism 8 includes a stabilizing bar 801, which is V-shaped. A top plate 802 is fixedly connected to the top of the stabilizing bar 801. A connecting rod 803 is fixedly connected to the rear end of the stabilizing bar 801. A transmission bar 804 is fixedly connected to both ends of the connecting rod 803. The transmission bar 804 is L-shaped, and the end of the transmission bar 804 away from the connecting rod 803 extends to the bottom of the bearing plate 10. An elastic rope 805 is fixedly connected to the bottom of the stabilizing bar 801. The elastic rope 805 is inclined and its bottom is fixedly connected to the surface of the base 2. A return spring 806 is sleeved on the outside of the elastic rope 805, and the two ends of the return spring 806 are fixedly connected to the bottom of the stabilizing bar 801 and the surface of the base 2, respectively.

[0032] When the load-bearing plate 10 moves downward due to the weight of the battery, it will push the L-shaped transmission bar 804 extending to its bottom to rotate. This will then pull the V-shaped stabilizing bar 801 to swing through the connecting rod 803, causing the top plate 802 at its top to automatically and accurately move toward and press against the corners of the battery. At the same time, the stretched elastic rope 805 and the return spring 806 store energy to provide a continuous and stable holding force for the clamping action, forming a four-point stabilizing structure that can automatically lock without manual intervention and effectively prevent the battery from shaking or shifting during transportation.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 8As shown, the auxiliary handling mechanism 9 includes a support frame 901. A collar 902 is fitted at the top of the support frame 901 and is fixedly connected to the bottom outer side of the stabilizing bar 801. The bottom of the support frame 901 passes through the base 2 and extends to its bottom. The connection between the support frame 901 and the base 2 is slidably connected. A fixing block 903 is fixedly connected to the bottom of the support frame 901. An electric push rod 904 is fixedly connected to the top of the fixing block 903 and is fixedly connected to the bottom of the base 2. An auxiliary wheel 905 is movably connected to the bottom of the fixing block 903 via a universal joint.

[0034] The electric push rod 904 extends to make the auxiliary wheel 905 contact the ground, which together with the original omnidirectional wheel 3 forms a wider and more stable support chassis, effectively lowering the center of gravity and preventing the risk of tipping over due to excessive battery weight. Specifically, the collar 902 is fixedly connected to the bottom outer side of the stabilizing bar 801. When the electric push rod 904 drives the support frame 901 to move downward, the collar 902 at the top of the support frame 901 moves downward synchronously. Since the collar 902 is fixedly connected to the stabilizing bar 801, the stabilizing bar 801 swings downward as a whole under the traction of the collar 902, so that the top plate 802 further presses the corner surface of the battery body 1. This improves stability during movement while completing the final locking step, ensuring double safety during the handling process.

[0035] In this embodiment, the drive motor 701 and the electric push rod 904 can be controlled in the following ways: (1) Manual control mode: Control buttons or switches are set near the base 2 or handle 6, and the operator can manually start and stop the drive motor 701 and electric push rod 904; (2) Automatic control mode: A pressure sensor can be installed on the surface of the bearing plate 10. When the battery body 1 is placed, the drive motor 701 is automatically triggered to start and adjust the height. When the pressure value exceeds the preset threshold, the electric push rod 904 is automatically triggered to extend and the auxiliary wheel 905 contacts the ground.

[0036] The above control methods can be selected or combined according to actual usage needs.

[0037] Working principle: After the battery body 1 is placed on the surface of the support plate 10, the drive motor 701 is started to drive the drive rod 702 to rotate. Through the forward and reverse thread transmission, the two cantilever 703 move towards each other on the surface of the drive rod 702, driving the adjustment wheel 704 to roll along the arc-shaped trajectory at the bottom of the contact bar 705. Under the action of the battery weight, the support plate 10 presses down on the compression spring 706 through the contact bar 705 to achieve adaptive adjustment of the bearing height. During the downward movement of the bearing plate 10, the transmission bar 804 is pushed to rotate around the connection point to a vertical position. The transmission bar 804 drives the stabilizing bar 801 to swing synchronously through the connecting rod 803, so that the top plate 802 is accurately positioned directly above the edge of the battery. During this process, the reset spring 806 and the elastic rope 805 are compressed and stored to provide a stable holding force for the clamping mechanism. The electric push rod 904 is controlled to push the fixed block 903 down, so that the auxiliary wheel 905 can reliably contact the ground. The support frame 901 moves down synchronously with the fixed block 903, and the stabilizing bar 801 is driven down as a whole through the collar 902 until the top plate 802 is tightly attached to the edge of the battery surface, forming a four-point stable clamping structure. The operator holds the handle 6 and pulls the base 2 to move via the pull rod 5. The casters 3 and auxiliary wheels 905 together form a stable mobile support system to ensure that the battery remains stable during transportation. After arriving at the destination, the unloading operation is performed. After locking the casters 3, the electric push rod 904 is controlled to retract, driving the auxiliary wheels 905 to lift off the ground. The drive motor 701 drives the carrier plate 10 to move upward a certain distance. At this time, the stabilizing bar 801 automatically releases its clamping state under the action of the return spring 806, and the battery can be smoothly moved out of the carrier plate 10, completing the entire handling process.
