Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for battery repair in new energy vehicles, and in particular to a battery repair bracket for new energy vehicles. Background Technology

[0002] As a crucial component of the vehicle's power system, the power battery of new energy vehicles typically requires inspection, maintenance, or replacement after a certain period of use. During maintenance, after the battery is removed from its installation location on the vehicle, it needs to be temporarily supported by a bracket or support structure to facilitate inspection, removal, and subsequent maintenance operations by maintenance personnel.

[0003] Existing battery trays primarily focus on battery installation and fixation, typically using bolts, pressure plates, or other fasteners to connect the battery to the tray. In repair scenarios, when technicians need to place the battery on the tray for removal and repositioning, using multiple bolts for fixation requires sequentially tightening or loosening the fasteners, resulting in numerous steps and reduced repair efficiency. Furthermore, bolts and other fasteners are prone to wear, stripping, or difficulty in tightening after repeated disassembly and reassembly, leading to unstable battery positioning on the tray.

[0004] Furthermore, if the battery is placed on the maintenance bracket and only supported by the bottom or simply limited by the sides, it may still shift position or wobble during maintenance, inspection, or relocation, which is detrimental to maintaining stability during maintenance. Therefore, it is necessary to provide a battery maintenance bracket for new energy vehicles that can support, lock, clamp, and quickly release the battery without relying on repeatedly removing and installing multiple bolts, thus facilitating battery placement, removal, inspection, and maintenance by maintenance personnel. To address this, a battery repair bracket for new energy vehicles is proposed. Summary of the Invention

[0005] In view of this, the present invention provides a battery maintenance bracket for new energy vehicles to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0006] The technical solution of this invention is implemented as follows: A battery repair bracket for new energy vehicles includes a mounting frame, two U-shaped plates, and a locking assembly. The mounting frame has an inner support space for placing the battery body to be repaired. The two U-shaped plates are respectively disposed on the left and right sides of the battery body to be repaired, and the battery body to be repaired and the two U-shaped plates are disposed inside the mounting frame. By providing U-shaped plates on the left and right sides of the battery body to be repaired, the battery body can form a cooperative relationship with the mounting frame and locking assembly after being placed in the mounting frame, thereby facilitating subsequent positioning, fixing, and removal / removal of the battery body to be repaired.

[0007] The outer side of the U-shaped plate has a slot for engaging with a plug in the locking assembly. When the battery to be repaired and the U-shaped plate are placed inside the mounting bracket, the plug can be inserted into the corresponding slot, causing the U-shaped plate to be in a limited position relative to the mounting bracket. When the plug is removed from the slot, the U-shaped plate is released from its limited position, and the maintenance personnel can pull the U-shaped plate towards the front of the mounting bracket, allowing the battery to be repaired to be moved out of the mounting bracket along with the U-shaped plate for inspection and maintenance.

[0008] The locking assembly is located at the bottom of the mounting frame and includes a transmission box, a servo motor, a forward and reverse threaded rod, two threaded sleeves, two connecting rods, two connecting discs, and two inserts. The transmission box is fixedly connected to the bottom of the mounting frame and is used to house and support the servo motor, the forward and reverse threaded rod, and the threaded sleeves, etc. The servo motor is located inside the transmission box, and the forward and reverse threaded rod is fixedly connected to the output end of the servo motor, enabling the servo motor to drive the forward and reverse threaded rod to rotate.

[0009] Two threaded sleeves are threadedly connected to opposite sides of the surface of the positive and negative threaded rods, respectively. Since the threads on both sides of the positive and negative threaded rods rotate in opposite directions, the two threaded sleeves can move synchronously towards each other or synchronously away from each other on the positive and negative threaded rods. Two connecting rods are fixedly connected to their respective threaded sleeves, two connecting discs are fixedly connected to their respective connecting rods, and two inserts are fixedly connected to the inner side of their respective connecting discs. Thus, the lateral movement of the threaded sleeves can be transmitted sequentially to the inserts through the connecting rods and connecting discs, causing the two inserts to synchronously move closer to or away from their respective U-shaped plates.

[0010] When the battery to be repaired needs to be secured within the mounting bracket, the servo motor drives the reciprocating threaded rods to rotate in one direction. This causes the two threaded sleeves to move the corresponding connecting rods, connecting discs, and inserts inward. The two inserts then insert into the slots on the outer sides of the corresponding U-shaped plates, thus limiting the movement of the two U-shaped plates and keeping the battery to be repaired inside the mounting bracket. When the battery to be repaired needs to be removed, the servo motor drives the reciprocating threaded rods to rotate in the opposite direction. This causes the two threaded sleeves to move the corresponding connecting rods, connecting discs, and inserts outward. The two inserts then disengage from their corresponding slots, releasing the limitation on the two U-shaped plates, allowing the repair personnel to pull the battery to be repaired out of the mounting bracket.

[0011] Furthermore, a limiting assembly is provided at the top of the mounting bracket. This limiting assembly includes a top plate, an adjusting bolt, a transmission plate, multiple springs, and a lower pressure plate. The top plate is fixedly connected to the top of the mounting bracket, and the adjusting bolt is threaded to the top of the top plate. By placing the limiting assembly at the top of the mounting bracket, the battery body to be repaired can be pressed and limited at the top after both sides are locked, thereby reducing the possibility of upper swaying or positional displacement of the battery body under repair support.

[0012] Furthermore, the bottom of the adjusting bolt is movably connected to the transmission plate via a bearing, and multiple springs are disposed at the bottom of the transmission plate, with the lower pressure plate disposed at the bottom of the springs. When the maintenance personnel rotate the adjusting bolt, the adjusting bolt can move up and down relative to the top plate, and drive the transmission plate to rise and fall via the bearing; when the transmission plate moves downward, the springs drive the lower pressure plate downward, causing the lower pressure plate to press against the top of the battery body to be repaired. The spring is located between the transmission plate and the lower pressure plate, which can form a certain buffer when the lower pressure plate contacts the battery body to be repaired, making the top pressing process more stable and avoiding the lower pressure plate directly and rigidly pressing against the battery body to be repaired.

[0013] Furthermore, a sliding groove is provided on the inner side of the top plate, and sliding rods are welded to both the left and right sides of the transmission plate. The outer sides of the sliding rods are slidably connected to the sliding groove. Through the cooperation of the sliding rods and the sliding groove, the up and down movement of the transmission plate can be guided, so that the transmission plate is less likely to deviate when it is raised and lowered by the adjusting bolt, thereby making the pressing position of the lower pressure plate on the top of the battery body to be repaired more stable.

[0014] Furthermore, a sliding groove is provided at the top of the inner cavity of the transmission box, and a slider is fixedly connected to the top of the threaded sleeve, with the top of the slider slidably connected within the sliding groove. Through the cooperation of the slider and the sliding groove, the process of the threaded sleeve moving axially along the positive and negative threaded rods can be guided, restricting the threaded sleeve from circumferentially rotating with the positive and negative threaded rods, thus enabling the threaded sleeve to more stably drive the connecting rod, connecting disc, and insert block to move.

[0015] Furthermore, a limiting groove is provided at the bottom of the transmission box, and the connecting rod passes through the limiting groove and extends to the bottom of the transmission box. When the connecting rod moves with the threaded sleeve, it can move along the limiting groove. The limiting groove can constrain the direction and range of movement of the connecting rod, so that the connecting rod drives the connecting plate and the insert block to maintain a relatively stable lateral movement state, which is conducive to the accurate insertion or withdrawal of the insert block into the slot on the outside of the U-shaped plate.

[0016] Furthermore, support rods are welded around the bottom of the mounting frame, and bases are welded to the bottom of the support rods. The cooperation of the support rods and bases creates a stable support between the mounting frame and the maintenance station or support surface, providing a stable foundation for the battery to be repaired when placed inside the mounting frame.

[0017] Furthermore, the base is threaded with mounting bolts on all four sides. These bolts secure the base to its designated support position, preventing displacement of the maintenance bracket during use and providing a stable foundation for placing, locking, clamping, and pulling out the battery to be repaired.

[0018] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention, through the cooperation of a mounting bracket, a U-shaped plate, a slot, and a locking assembly, allows the battery to be repaired to be placed on the mounting bracket and then locked by inserting a plug into the slot on the outside of the U-shaped plate. When it is necessary to remove the battery to be repaired, a servo motor can drive the positive and negative threaded rods to rotate, causing the two threaded sleeves to drive the plug out of the slot via the connecting rod and connecting plate, thereby releasing the restriction on the U-shaped plate. This makes it easier for maintenance personnel to pull the battery to be repaired out of the mounting bracket, reducing the need for repeated disassembly and reassembly of multiple bolts during the maintenance process.

[0019] Second, the present invention uses the cooperation of the top plate, adjusting bolt, transmission plate, spring and lower pressure plate to enable the lower pressure plate to press on the top of the battery body to be repaired, forming a vertical limit on the battery body to be repaired; at the same time, the sliding rod and sliding groove cooperate to guide the up and down movement of the transmission plate, so that the battery body to be repaired maintains a relatively stable placement state under the repair support state.

[0020] Third, this invention guides the lateral movement of the threaded sleeve through the cooperation of the slider and the sliding groove, and constrains the movement path of the connecting rod through the limiting groove, making it less prone to deviation when the connecting rod moves the connecting plate and the insert, which is conducive to the stable insertion or withdrawal of the insert from the slot; at the same time, the support rod, the base and the mounting bolts form a support and fixation for the mounting frame, providing a stable foundation for supporting, locking and removing the battery body to be repaired. The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, this embodiment of the invention provides a battery repair bracket for new energy vehicles, including a mounting frame 1, a battery body 3 to be repaired, two U-shaped plates 4, and a locking assembly 8. The mounting frame 1 has an inner support space for placing the battery body 3 to be repaired. The battery body 3 is placed inside the mounting frame 1. The two U-shaped plates 4 are respectively disposed on the left and right sides of the battery body 3. The battery body 3 can be placed into the mounting frame 1 along with the two U-shaped plates 4, or it can be removed from the mounting frame 1 along with the U-shaped plates 4 after the locking mechanism is released. Each of the two U-shaped plates 4 has a slot 9 on its outer side. The slot 9 is used to cooperate with the insert block 804 in the locking assembly 8, allowing the U-shaped plates 4 to be locked or unlocked relative to the mounting frame 1.

[0027] The locking assembly 8 is located at the bottom of the mounting bracket 1. The locking assembly 8 includes a transmission box 801, a servo motor 806, a forward and reverse threaded rod 808, two threaded sleeves 807, two connecting rods 810, two connecting discs 805, and two insert blocks 804. The transmission box 801 is fixedly connected to the bottom of the mounting bracket 1 and is used to house and support the transmission components such as the servo motor 806, the forward and reverse threaded rod 808, and the threaded sleeves 807. The servo motor 806 is located on the left side of the inner cavity of the transmission box 801, and its output end is fixedly connected to the forward and reverse threaded rod 808, enabling the servo motor 806 to drive the forward and reverse threaded rod 808 to rotate synchronously after startup.

[0028] Two threaded sleeves 807 are threadedly connected to both sides of the surface of the positive and negative threaded rod 808. Since the threads on both sides of the positive and negative threaded rod 808 are in opposite directions, when the positive and negative threaded rod 808 rotates in one direction, the two threaded sleeves 807 can move synchronously inward along the positive and negative threaded rod 808; when the positive and negative threaded rod 808 rotates in opposite directions, the two threaded sleeves 807 can move synchronously outward along the positive and negative threaded rod 808. Two connecting rods 810 are fixedly connected to the corresponding threaded sleeves 807, two connecting discs 805 are fixedly connected to one end of the corresponding connecting rod 810, and two inserts 804 are fixedly connected to the inner side of the corresponding connecting disc 805. Thus, the movement of the threaded sleeves 807 can be transmitted to the inserts 804 through the connecting rods 810 and the connecting discs 805, allowing the two inserts 804 to synchronously move closer to or further away from the corresponding U-shaped plate 4.

[0029] In this embodiment, a sliding groove 802 is provided at the top of the inner cavity of the transmission box 801, and a slider 803 is fixedly connected to the top of the threaded sleeve 807. The top of the slider 803 is slidably connected within the sliding groove 802. Through the cooperation of the slider 803 and the sliding groove 802, the lateral movement of the threaded sleeve 807 can be guided, allowing the threaded sleeve 807 to move in a predetermined direction during the rotation of the positive and negative threaded rods 808, reducing the possibility of the threaded sleeve 807 deflecting with the positive and negative threaded rods 808. A limiting groove 809 is provided at the bottom of the transmission box 801, and the connecting rod 810 passes through the limiting groove 809 and extends to the bottom of the transmission box 801. When the connecting rod 810 moves with the threaded sleeve 807, it moves along the limiting groove 809. The limiting groove 809 can constrain the movement path of the connecting rod 810, ensuring a relatively stable lateral movement state when the connecting rod 810 drives the connecting disc 805 and the insert block 804.

[0030] A limiting assembly 2 is provided on the top of the mounting frame 1. The limiting assembly 2 includes a top plate 201, an adjusting bolt 207, a transmission plate 204, multiple springs 202, and a lower pressure plate 203. The top plate 201 is fixedly connected to the top of the mounting frame 1, the adjusting bolt 207 is threadedly connected to the top of the top plate 201, and the bottom of the adjusting bolt 207 is movably connected to the transmission plate 204 via a bearing. Multiple springs 202 are provided at the bottom of the transmission plate 204, and the lower pressure plate 203 is provided at the bottom of the springs 202. When the maintenance personnel rotate the adjusting bolt 207, the adjusting bolt 207 can move up and down relative to the top plate 201, and drive the transmission plate 204 to rise and fall via the bearing; when the transmission plate 204 moves downward, the lower pressure plate 203 moves downward via the springs 202, so that the lower pressure plate 203 presses against the top of the battery body 3 to be repaired, forming a vertical limit on the battery body 3 to be repaired.

[0031] A groove 205 is provided on the inner side of the top plate 201. Slide rods 206 are welded to both the left and right sides of the transmission plate 204, with the outer sides of the slide rods 206 slidably connected to the groove 205. When the transmission plate 204 moves up and down under the action of the adjusting bolt 207, the slide rods 206 move along the groove 205, thereby guiding the lifting and lowering process of the transmission plate 204 and preventing it from tilting. Since the lower pressure plate 203 is connected to the bottom of the transmission plate 204 via a spring 202, the stable movement of the transmission plate 204 helps to ensure that the lower pressure plate 203 is pressed more smoothly onto the top of the battery body 3 to be repaired.

[0032] Support rods 7 are welded to all four sides of the bottom of the mounting bracket 1. A base 6 is welded to the bottom of the support rods 7, and mounting bolts 5 are threaded to all four sides of the base 6. The support rods 7 are used to support the mounting bracket 1, so that a certain height support space is formed between the mounting bracket 1 and the base 6. The base 6 is used to support the mounting bracket 1 and the battery body 3 to be repaired above it. The mounting bolts 5 can be used to fix the base 6 to the repair station or the corresponding support surface, so that the repair bracket remains stable during battery placement, locking, clamping, and removal.

[0033] In use, the battery body 3 to be repaired and its U-shaped plates 4 on both sides are placed inside the mounting frame 1, with the slots 9 on the outer side of the U-shaped plates 4 corresponding to the positions of the inserts 804. Then, the servo motor 806 is started, driving the positive and negative threaded rods 808 to rotate. The positive and negative threaded rods 808, through the threads on both sides of their surfaces, drive the two threaded sleeves 807 to move inward synchronously. As the threaded sleeves 807 move, the slider 803 slides along the sliding groove 802, and the connecting rod 810 moves along the limiting groove 809. The threaded sleeves 807, through the connecting rod 810, drive the connecting plate 805 to move inward, and the connecting plate 805 drives the inserts 804 to move inward, so that the two inserts 804 are respectively inserted into the slots 9 on the outer side of the corresponding U-shaped plates 4. At this time, the two U-shaped plates 4 form a limiting state relative to the mounting frame 1, and the battery body 3 to be repaired remains inside the mounting frame 1.

[0034] After the battery body 3 to be repaired is locked on both sides, the repair personnel can rotate the adjusting bolt 207 to move it downward relative to the top plate 201. The adjusting bolt 207 drives the transmission plate 204 to move downward, and the slide rods 206 on both sides of the transmission plate 204 slide downward along the slide groove 205. The transmission plate 204 drives the lower pressure plate 203 to move downward through the spring 202 until the lower pressure plate 203 presses down on the top of the battery body 3 to be repaired. At this time, the battery body 3 to be repaired is limited on both sides by the cooperation of the U-shaped plate 4 and the insert block 804, and is pressed and limited at the top by the lower pressure plate 203, thus maintaining a relatively stable placement under the repair support condition.

[0035] When the battery body 3 needs to be removed for inspection and maintenance, the adjusting bolt 207 can be rotated in the reverse direction first to move the transmission plate 204 and the lower pressure plate 203 upward, releasing the pressure limit of the lower pressure plate 203 on the top of the battery body 3. Then, the servo motor 806 is started in the reverse direction, causing the servo motor 806 to drive the forward and reverse threaded rods 808 to rotate in the opposite direction. The forward and reverse threaded rods 808 drive the two threaded sleeves 807 to move outward synchronously. The threaded sleeves 807 drive the two inserts 804 to move outward through the connecting rod 810 and the connecting plate 805, causing the inserts 804 to exit the corresponding slots 9. After the inserts 804 exit the slots 9, the U-shaped plate 4 is released from its limit relative to the mounting frame 1. The maintenance personnel can then pull the U-shaped plate 4 towards the front of the mounting frame 1, so that the battery body 3 to be repaired can be removed from the mounting frame 1 along with the U-shaped plate 4 for subsequent inspection, maintenance, or replacement operations.

[0036] With the above-mentioned structural design, the present invention can support, lock both sides and press the top of the battery body 3 to be repaired during the repair of new energy vehicle batteries. It can also realize the insertion and removal of the plug 804 and the slot 9 through the locking component 8, reducing the repeated disassembly and assembly of multiple bolts during the repair process, and making it easier for repair personnel to pick up, put down and maintain the battery body 3 to be repaired.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
