Description

Technical Field

[0001] This invention relates to the field of commercial vehicle battery assembly equipment technology, and in particular to a side-mounted battery disassembly device for pure electric heavy-duty commercial trucks. Background Technology

[0002] Currently, the battery pack layout in the pure electric heavy-duty truck industry is gradually evolving from a rear-mounted design on the upper side of the frame to a side-mounted layout where battery packs are suspended on both sides of the frame. Existing battery assembly platforms generally use a lifting mechanism driven by hydraulic cylinders and motors, along with a roller platform, to lift the battery pack from the inside of the battery frame for assembly. During operation, the lifting mechanism is in direct contact with the battery pack and bears the entire load. Due to uneven stress and assembly vibrations, the battery pack is prone to circumferential rotational displacement. After long-term repeated operation, the lifting plane of the lifting mechanism will deform and warp, directly leading to tilting and loss of levelness of the lifting plane.

[0003] Tilts the lifting plane, causing uneven stress on the battery pack and resulting in pack tilting, which can easily damage the battery casing and sealing structure, posing a battery safety hazard. Furthermore, an uneven lifting surface increases the resistance during battery assembly and makes alignment with the battery frame mounting position more difficult. Simultaneously, existing equipment requires workers to repeatedly adjust the relative positions of the battery pack and battery frame during assembly, a cumbersome process that significantly reduces assembly efficiency and makes it difficult to guarantee the overall installation accuracy of the battery pack, failing to meet the demands of large-scale, high-precision mass production assembly of side-mounted batteries. These problems urgently need to be addressed. Summary of the Invention

In the description of this invention, "a plurality of" means at least two, such as two, three, or more, unless otherwise explicitly specified.

[0025] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] To address the problems existing in the prior art, this application provides a side-mounted battery packing device for pure electric heavy-duty commercial trucks.

[0027] like Figures 1-3As shown, a side-mounted battery assembly device for a pure electric heavy-duty commercial truck includes a battery pack conveying device 1; a battery support platform 2; and a frame lifting platform 3. The battery support platform 2 is fixedly installed, such as on a base 4, to support the battery pack A and adjust its position. The frame lifting platform 3 supports and drives the battery frame B to move up and down to adjust its relative position to the battery pack A, and has at least a first mounting position and a second mounting position along the lifting direction, thereby installing the battery pack A on each layer of the multi-layered battery frame B. The battery pack conveying device 1 has a battery pack placement area along the conveying direction. The battery pack unloading position is adjacent to the battery support platform 2, and the top surface of the battery pack A supported by the battery pack conveying device 1 is roughly flush with the top surface of the battery support platform 2. It can be completely flush or there can be a certain height difference, such as within ±3mm. Specifically, it is based on the requirement that the battery pack A can be smoothly conveyed from the top surface of the battery pack conveying device 1 to the top surface of the battery support platform 2. When the frame lifting platform 3 is located in the first installation position or the second installation position, the side opening of the battery frame B is opposite to the battery pack A, so that the battery pack A can enter the battery support platform 2 inside the battery frame B from the side of the battery frame B.

[0028] This invention mainly provides a side-mounted battery installation device for pure electric heavy-duty commercial trucks. It utilizes a fixed battery support platform 2 to support battery pack A, and a frame lifting platform 3 to support battery frame B and move it between different installation positions. This allows battery pack A to be installed on different layers within the multi-layered battery frame B. By adjusting the position of the battery frame B, compared to adjusting the position of the battery pack A, the problem of deformation of the lifting platform during long-term load-bearing and position adjustment of battery pack A is avoided, further reducing the probability of damage to battery pack A. Furthermore, the ability of battery pack A to adjust its position on the battery support platform facilitates the alignment and installation between battery pack A and battery frame B. The battery pack conveying device 1 transports battery pack A, saving time and effort, and making it easy to transfer battery pack A to the battery support platform.

[0029] In some preferred embodiments, the frame lifting platform 3 includes a support frame 31, a lifting assembly 32, and a control assembly 33. The top surface of the support frame 31 supports the battery frame B and has a clearance portion corresponding to the position of the battery support platform 2. The lifting end of the lifting assembly 32 is connected to the support frame 31 to drive the support frame 31 to lift at least between a first mounting position and a second mounting position. The control assembly 33 is connected to the lifting assembly 32 and is used to control the lifting assembly 32 to stop working when the support frame 31 is in the first mounting position or the second mounting position. Based on controlling the lifting position of the support frame 31 with the control assembly 33, the position control is more accurate and faster, which can improve equipment efficiency.

[0030] Preferably, the support frame 31 is a square frame adapted to the battery frame B, with the top surface supporting the battery frame B and the bottom surface connected to the lifting end of the lifting assembly 32.

[0031] Preferably, such as Figure 4 and Figure 5 As shown, the control component 33 includes a paddle 331, a sensing element 332, and a controller 333; the paddle 331 is mounted on the support frame 31; the sensing element 332 is fixed on the moving line of the paddle 331, and when the support frame 31 is in the first mounting position or the second mounting position, it cooperates with the paddle 331 to generate a trigger signal; the controller 333 is connected to the sensing element 332 and the lifting component 32, so as to control the lifting component 32 to stop working when the trigger signal is received.

[0032] Preferably, the sensing element 332 is mechanically contact-triggered, such as a limit switch, or non-contact-triggered, such as a proximity switch.

[0033] Preferably, the sensing element 332 is a limit switch and includes a body 3321, a lever 3322, and a roller 3323; the trigger end of the body 3321 is connected to one end of the lever 3322, and the body 3321 is connected to the controller 333; the other end of the lever 3322 is rotatably connected to the roller 3323; the roller 3323 is positioned with its wheel surface facing the surface of the lever 331 and is located on the movement path of the lever 331, so that it is driven by the lever 3322 to rotate the trigger end, thereby causing the body 3321 to generate a trigger signal. Based on the mechanically triggered sensing element 332, the triggering is more reliable. Furthermore, the roller 3323 and the lever 331 make rotating contact, reducing friction and wear, ensuring timely and accurate triggering. This ensures that the support bracket 31 can stably and accurately stop at the first or second mounting position. Taking the second mounting position as higher than the first mounting position as an example, during the assembly of battery pack A, the battery frame B is installed sequentially from the top to the bottom. As the support bracket 31 reaches the first mounting position, the lever 331 drives the roller 3323, which in turn drives the lever 3322 to rotate, causing the body 3321 to generate a trigger signal. After receiving the trigger signal, the controller 333 controls the lifting assembly 32 to stop working, and the support bracket 31 stops at the first mounting position. In the first installation position, battery pack A is installed. After installation, controller 333 controls lifting assembly 32 to drive support frame 31 to continue rising. During this process, roller 3323 and lever 331 move relative to each other. Specifically, roller 3323 rolls on the surface of lever 331. When support frame 31 reaches the second installation position, lever 331 drives roller 3323 of sensing element 332 corresponding to the second installation position, which in turn drives lever 3322 to rotate, causing body 3321 to generate a trigger signal. After receiving the trigger signal, controller 333 controls lifting assembly 32 to stop working, support frame 31 stays in the second installation position, and battery pack A is installed. Thus, the installation of battery pack A in each layer of battery frame B is completed in sequence.

[0034] More preferably, the lever 3322 is perpendicular to the moving direction of the paddle 331, and the roller 3323 contacts the paddle 331 at the half-wheel position of the roller 3323 furthest from the lever 3322. Based on this, the lever arm of the paddle 331 relative to the trigger end of the body 3321 is longer, making triggering easier. Preferably, the lever 3322 is perpendicular to the trigger end of the body 3321.

[0035] More preferably, the lever 3322 has a mounting hole 33221 and a connecting slot 33222 connecting the mounting hole 33221 and the end away from the roller 3323; the lever 3322 is secured to the trigger end of the body 3321 by a bolt threaded onto one side of the connecting slot 33222. This facilitates the fixed installation of the lever 3322 and allows for easy adjustment of the lever 3322's installation angle.

[0036] Preferably, it includes a plurality of sensing elements 332, each sensing element 332 being disposed corresponding to a first mounting position or a second mounting position.

[0037] Preferably, the two ends of the lever 331 in the lifting direction are bent away from the roller 3323, and the bent surface is disconnected from the roller 3323; thus, it does not affect the lever 331 from pushing the roller 3323 to move, and can quickly rotate the lever 3322 to the trigger angle.

[0038] In some preferred embodiments, such as Figure 1 and Figure 2 As shown, the support frame 31 includes a frame body 311, a first limiting member 312, and a second limiting member 313. The frame body 311 is installed on the lifting end of the lifting assembly 32, and its top surface is used to support the battery frame B. The first limiting member 312 and the second limiting member 313 are respectively fixed to the frame body 311 and protrude from the top surface of the frame body 311. The first limiting member 312 is used to limit the battery frame B in a first direction, and the second limiting member 313 is used to limit the battery frame B in a second direction. By limiting the battery frame B with the first limiting member 312 and the second limiting member 313, the position of the battery frame B is ensured to be stable and accurate, thereby improving the relative position accuracy between the battery frame B and the battery pack A during assembly, facilitating the installation and fixing of the two, and improving installation efficiency.

[0039] Preferably, the first direction is the length direction of the battery frame B, and the second direction is the width direction of the battery frame B. Based on this, the first limiting member 312 and the second limiting member 313 provide more stable positioning of the battery frame B.

[0040] More preferably, there are multiple first limiting members 312 and / or second limiting members 313, with multiple first limiting members 312 spaced apart along the length direction of the battery frame B, and multiple second limiting members 313 spaced apart along the width direction of the battery frame B.

[0041] Preferably, the first limiting member 312 and / or the second limiting member 313 are limiting plates, and the plate surface is used to limit contact with the battery frame B.

[0042] Preferably, the support frame 31 further includes a first pad 314 and a second pad 315. There are two first pads 314, which are spaced apart on the top surface of the frame 311 along the length of the battery frame B, and are used to support the bottom ends of the battery frame B. There are multiple second pads 315, which are arranged along the edge of the frame 311 and correspond to the bottom edge of the battery frame B, and are used to support the bottom edge of the battery frame B.

[0043] More preferably, the top surfaces of the first pad 314 and the second pad 315 include a polyurethane material layer; based on this, paint peeling and deformation caused by direct contact between the battery frame B and the support frame 31 are avoided, and the high coefficient of friction can prevent relative displacement between the battery frame B and the support frame 31 during the assembly of the battery pack A.

[0044] In some preferred embodiments, such as Figure 1 and Figure 2 As shown, the lifting assembly 32 includes a drive member 321, a transmission rod 322, and a ball screw mechanism 323; the moving end of the ball screw mechanism 323 is connected to the support frame 31; the drive member 321 drives the ball screw mechanism 323 to move through the transmission rod 322. By using the ball screw mechanism 323 as the transmission member, the rotation of the drive member 321 is converted into linear movement of the support frame 31. This prevents the support frame 31 from moving downwards under gravity when it is in the first or second mounting position, thus ensuring the stability of the support frame 31 in the first or second mounting position.

[0045] Preferably, the drive unit 321 can be a forward and reverse rotating motor.

[0046] In some preferred embodiments, such as Figure 1 and Figure 2 As shown, it includes multiple transmission rods 322 and multiple ball screw mechanisms 323; the multiple ball screw mechanisms 323 are spaced apart along the length direction of the support frame 31 and are respectively connected to the drive member 321 through the transmission rods 322.

[0047] Preferably, multiple ball screw mechanisms 323 are arranged along the length of the support frame 31 and located at both ends of the support frame 31, thereby improving the stability of the lifting process of the support frame 31.

[0048] Preferably, the drive unit 321 can be a dual-axis motor that can rotate in both directions to drive the two transmission rods 322 simultaneously. This improves the consistency of the operation of the ball screw mechanism 323 and avoids jamming caused by inconsistent lifting speeds of the ball screw mechanism 323.

[0049] In some preferred embodiments, such as Figure 1 and Figure 2 As shown, the frame lifting platform 3 also includes a guide member 34; the guiding direction of the guide member 34 is consistent with the lifting direction of the lifting assembly 32, and the guide member 34 is used to guide the lifting direction of the support frame 31; based on the guide member 34 guiding the lifting direction of the support frame 31, the movement direction of the support frame 31 is limited to the height direction of the battery frame B, ensuring the stability of the support frame 31 during the lifting process.

[0050] Preferably, the guide member 34 is a telescopic rod structure, with the telescopic end connected to the support frame 31.

[0051] Preferably, it includes multiple guide members 34, which are spaced apart around the circumference of the support frame 31. For example, if the support frame 31 is square, four guide members 34 are provided, which are respectively provided at the four corners of the support frame 31.

[0052] Preferably, the system also includes a base 4, with the lifting assembly 32 and guide member 34 respectively mounted on the base 4.

[0053] In some preferred embodiments, such as Figure 1 and Figure 2 As shown, the battery support platform 2 includes a platform body 21 and multiple universal ball bearings 22; the universal ball bearings 22 are arranged on the top plane of the platform body 21; the multiple universal ball bearings 22 are spaced apart to support the battery pack A. Based on this, the battery pack A is placed on the multiple universal ball bearings 22. At this time, the battery pack A can be pushed to adjust its position, such as pushing the battery pack A along the length or width direction of the battery pack A, thereby adjusting the relative position of the battery pack A and the battery frame B, ensuring that the battery pack A and the battery frame B are aligned and installed.

[0054] Preferably, it includes multiple battery support platforms 2; the multiple battery support platforms 2 are spaced apart along the length direction of the battery pack A.

[0055] Specifically, it includes two battery support platforms 2, which are positioned opposite each other at both ends of the length of the battery pack A to support both sides of the length of the battery pack A, thereby improving the stability of the support.

[0056] In some preferred embodiments, such as Figure 1 and Figure 3 As shown, the battery pack conveying device 1 includes a conveying guide rail 11, a conveying trolley 12, and a conveying roller 13. The top surface of the conveying trolley 12 serves as the bearing surface for the battery pack A and can move along the conveying guide rail 11 between the battery pack placement position and the battery pack unloading position. The conveying roller 13 is disposed on the top surface of the conveying trolley 12 to support the battery pack A, and its rolling direction is towards the battery support platform 2. Based on the method of conveying the battery pack A by the conveying trolley 12 moving along the conveying guide rail 11, the working efficiency is higher, and the support of the battery pack A by the conveying roller 13 makes it easier to transport the battery pack A from the battery pack conveying device 1 to the battery support platform 2. In conjunction with the battery support platform 2, which supports the battery pack A with multiple omnidirectional ball bearings 22, the requirements for directional accuracy during the transfer of the battery pack A can be reduced.

[0057] Preferably, there are multiple conveying rollers 13 for conveying, and the multiple conveying rollers 13 are arranged in parallel and spaced apart to jointly support the battery pack A.

[0058] In some preferred embodiments, such as Figure 1 and Figure 3 As shown, it also includes a limiting member 14; the limiting member 14 is disposed on the conveying guide rail 11 to limit the movement range of the conveying trolley 12, and when the conveying trolley 12 is limited by the limiting member 14, the conveying trolley 12 is located at the battery pack unloading position.

[0059] Preferably, the limiting member 14 can be a limiting baffle; blocking the movement path of the conveying trolley 12.

[0060] The working process of the battery packaging device of the present invention is as follows: Taking a double-layer battery frame B, with the second mounting position higher than the first mounting position, as an example: During the assembly of battery pack A, the battery frame B is installed sequentially from the top to the bottom. First, the support bracket 31 is adjusted to the first installation position. During the process of the support bracket 31 reaching the first installation position, the lever 331 drives the roller 3323 to rotate the lever 3322, causing the main body 3321 to generate a trigger signal. After receiving the trigger signal, the controller 333 controls the lifting component 32 to stop working, and the support bracket 31 stays in the first installation position. The transport trolley 12 moves to the battery pack placement position, as follows: Figure 6 At the position of the conveying trolley 12, place the battery pack A on the conveying roller 13, move the conveying trolley 12 to the battery pack unloading position blocked by the limiting member 14, and push the battery pack A towards the battery support platform 2 until the battery pack A is pushed onto the battery support platform 2. Adjust the relative positions of battery pack A and battery frame B until they are aligned at the mating mounting positions, and then fix battery pack A and battery frame B together. After installation, the controller 333 controls the lifting assembly 32 to continue raising the support frame 31. During this process, the roller 3323 moves relative to the lever 331, specifically, the roller 3323 rolls on the surface of the lever 331. When the support frame 31 reaches the second installation position (e.g., ...), ... Figure 6 During the process of positioning the battery frame B, the lever 331 drives the roller 3323 of the sensing element 332 corresponding to the second mounting position to rotate, causing the main body 3321 to generate a trigger signal. After receiving the trigger signal, the controller 333 controls the lifting assembly 32 to stop working, and the support frame 31 stays in the second mounting position. The above steps are repeated to complete the installation of battery pack A. Thus, the installation of battery pack A on each layer of battery frame B is completed in sequence.
