[0001] This utility model belongs to the field of heavy-duty truck battery swapping technology, specifically relating to a heavy-duty truck battery swapping assembly. Background Technology

[0002] With the gradual popularization of electric new energy vehicles, the application of new energy electric heavy trucks is also becoming more and more widespread. At present, in order to ensure the energy replenishment of new energy electric heavy trucks, the battery compartment is usually replaced as a whole. The specific operation steps of new energy electric heavy trucks are as follows: First, the new energy electric heavy truck drives into the battery swapping station. The depleted battery compartment is lifted out by hoisting equipment, and the fully charged battery compartment is hoisted back onto the truck. The battery compartment is then fixed to the lower bracket by fixing components, thereby completing the battery swapping process of the heavy truck.

[0003] In existing technologies, the battery compartment and lower bracket of heavy trucks are mainly connected and assembled by bolts and clips. Whether bolts or clips are used, manual assistance is required during actual operation, which makes the battery swapping process of heavy truck battery swapping assembly cumbersome and complicated. In addition, there are certain safety hazards during manual operation, resulting in poor battery swapping safety of heavy truck battery swapping assembly.

[0004] Therefore, in order to address the aforementioned technical issues, it is necessary to provide a heavy-duty truck battery swapping assembly.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a heavy-duty truck battery swapping assembly, including: a battery swapping base, a battery bracket, a pair of pneumatic locking mechanisms, and a pair of auxiliary positioning mechanisms.

[0008] A battery holder is mounted on top of the battery swapping base.

[0009] A pair of pneumatic locking mechanisms are symmetrically mounted on the top of the battery swapping base. Each pneumatic locking mechanism includes a pair of clamping bases, which are respectively fixedly mounted on both sides of the battery swapping base. A pressure rod is hinged to the top of each pair of clamping bases. A drive side plate is hinged to the outer side of each pair of clamping bases.

[0014] In one or more embodiments of this utility model, a pair of locking cylinders are hingedly mounted on the frame base plate, and the telescopic shafts of both locking cylinders are hinged to the drive side plate. By controlling the telescopic movement of the locking cylinder telescopic shafts, the drive side plate can be pulled and controlled, thereby enabling synchronous lifting control of the drive side plate.

[0015] In one or more embodiments of this utility model, a positioning cylinder is fixedly connected to the side of the auxiliary positioning post close to the clamping base, and the telescopic end of the positioning cylinder is fixedly connected to the positioning block. By controlling the movement of the telescopic end of the positioning cylinder, the positioning block is moved synchronously, thereby controlling the positioning and clamping state of the positioning block and the compression limiting block. A compression limiting block is arranged below the positioning block, and the compression limiting block is fixedly assembled above the battery tray. The compression engagement between the compression limiting block and the positioning block can limit the connection between the battery tray and the positioning block.

[0016] In one or more embodiments of this utility model, the lower surface of the locking head and the upper surface of the locking block are both inclined toward the side close to the clamping base, and the lower surface of the positioning block and the upper surface of the compression limiting block are both inclined toward the side close to the auxiliary positioning post.

[0017] In one or more embodiments of this utility model, a plurality of evenly distributed auxiliary guide frames are fixedly connected to the battery swapping base, and the auxiliary guide frames are arranged between the positioning post and the clamping base. The auxiliary guide frames serve to limit the assembly of the side guide bearings. Side guide bearings are rotatably connected above each of the plurality of auxiliary guide frames. The rolling of the plurality of side guide bearings can guide and limit the battery tray.

[0018] In one or more embodiments of this utility model, a mounting base is fixedly connected to the middle of the battery tray. The battery terminal connector is assembled and fixed via the mounting base. A fixed base plate is fixedly connected to the battery swapping base at a position corresponding to the mounting base. The fixed base plate supports and fixes multiple sets of supporting pins. Multiple sets of evenly distributed supporting pins are fixedly connected to the fixed base plate. The socket plate is guided to move up and down via the multiple sets of supporting pins.

[0019] In one or more embodiments of this utility model, a socket plate is inserted and assembled above the multiple sets of supporting pins. The socket plate limits the insertion of the battery terminal connector. A spring is sleeved on the outer side of each set of supporting pins, and the spring is positioned between the socket plate and the fixed base plate. The spring supports and limits the socket plate, thus providing flexible support through the contraction or return of the spring. A positioning nut is threaded to one end of each set of supporting pins above the socket plate. The positioning nut limits the movement of the socket plate. A cotter pin is inserted at the top of each set of supporting pins, located above the positioning nut. The cotter pin prevents the socket plate from detaching and limits its movement.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1 to 7 As shown, a heavy-duty truck battery swapping assembly according to one embodiment of the present invention includes: a battery swapping base 1, a battery bracket 101, a pair of pneumatic locking mechanisms 2 and a pair of auxiliary positioning mechanisms 3.

[0033] like Figure 1 As shown, a battery holder 101 is mounted on top of the battery swapping base 1. The battery holder 101 is used to support and limit the position of the battery.

[0034] like Figure 3 As shown, multiple limiting pads 102 are fixedly connected to the top of the battery swapping base 1. By setting multiple limiting pads 102 on the top of the battery swapping base 1, the battery bracket 101 can be flexibly supported, reducing the direct collision between the battery bracket 101 and the battery swapping base 1, thus reducing wear and deformation.

[0035] like Figures 1 to 3 As shown, multiple sets of evenly distributed positioning posts 103 are fixedly connected to the inner wall of the battery swapping base 1, and multiple sets of guide plates 104 are fixedly connected to the inner wall of the battery bracket 101. The multiple sets of guide plates 104 are inserted and engaged with the positioning posts 103. The battery bracket 101 and the battery swapping base 1 are positioned during the assembly process through the insertion and engagement of the positioning posts 103 and the guide plates 104.

[0036] like Figures 1 to 3 As shown, a pair of pneumatic locking mechanisms 2 are symmetrically assembled above the battery swapping base 1. The pneumatic locking mechanism 2 includes a pair of clamping bases 201, which are respectively fixedly assembled on both sides of the battery swapping base 1. The clamping bases 201 serve to limit the assembly of the pressure rod 202.

[0037] like Figure 3 As shown, a rack base plate 207 is fixedly connected to the bottom of each pair of clamping bases 201, and the rack base plate 207 is fixedly connected to the side wall of the battery swapping base 1. The rack base plate 207 provides support and limits the clamping bases 201 and the locking block 210.

[0038] like Figures 1 to 3As shown, each of the pair of clamping bases 201 is hinged to a pressure rod 202. The pressure rod 202 serves to limit the assembly and control the movement of the locking positioning rod 205. By controlling the lifting or pressing down of the pressure rod 202, the locking head 209 is controlled to press the locking block 210.

[0039] like Figures 1 to 2 As shown, a pair of clamping bases 201 are each hinged to the outer side with a drive side plate 203. The drive side plate 203 performs assembly limiting and pulling drive control on the pressure rod 202.

[0040] like Figures 1 to 3 As shown, a pair of locking cylinders 211 are hinged to the frame base plate 207, and the telescopic shafts of both locking cylinders 211 are hinged to the drive side plate 203. By controlling the telescopic movement of the locking cylinders 211, the drive side plate 203 can be pulled and controlled, thereby enabling synchronous lifting control of the drive side plate 203.

[0041] like Figures 1 to 2 As shown, a linkage plate 204 is hinged between each pair of drive side plates 203 and pressure rod 202, with the linkage plate 204 located at the middle of the pressure rod 202. The linkage plate 204 can connect and limit the drive side plates 203 and pressure rod 202, so that the pressure rod 202 can move synchronously with the drive side plates 203 under the action of the linkage plate 204.

[0042] like Figures 1 to 2 As shown, a locking positioning rod 205 is slidably inserted into one end of the pressure rod 202 outside the clamping base 201. The locking positioning rod 205 supports and fixes the locking head 209. Through the cooperation of the locking positioning rod 205, the locking head 209 and the pressure rod 202, the locking block 210 can be pressed, thereby enabling the pneumatic locking mechanism 2 to lock and position the battery holder 101.

[0043] like Figures 1 to 2 As shown, a limit nut 208 is threadedly connected to the upper end of the locking positioning rod 205, and the limit nut 208 is positioned above the pressure rod 202. The cooperation between the limit nut 208 and the pressure rod 202 serves to prevent the locking positioning rod 205 from disengaging.

[0044] like Figures 1 to 2 As shown, a locking head 209 is fixedly connected to the lower end of the locking positioning rod 205, and a disc spring 206 is arranged between the locking head 209 and the pressure rod 202. The battery tray 101 is clamped and fixed by the locking head 209 clamping and fixing the locking cylinder 211. A locking block 210 is arranged below the locking head 209, and the locking block 210 is fixedly assembled above the battery tray 101.

[0045] Specifically, the lower surface of the locking head 209 and the upper surface of the locking block 210 are both inclined towards the side close to the clamping base 201. The inclined surface design ensures the contact area between the locking head 209 and the locking block 210, and at the same time improves the locking stability of the locking head 209 and the locking block 210.

[0046] like Figures 1 to 2 As shown, a disc spring 206 is sleeved on the outer side of the locking positioning rod 205. The disc spring 206 supports and limits the locking head 209.

[0047] like Figure 5 As shown, a pair of auxiliary positioning mechanisms 3 are symmetrically assembled on both sides of the battery swapping base 1. Each auxiliary positioning mechanism 3 includes an auxiliary positioning post 301, which is fixedly mounted on the top of the battery swapping base 1. The auxiliary positioning post 301 serves to assemble and fix the positioning cylinder 304, and at the same time, it can guide the positioning block 303 to slide.

[0048] like Figure 5 As shown, a guide bearing 302 is rotatably mounted above the auxiliary positioning post 301. The rolling of the guide bearing 302 can guide the assembly of the battery bracket 101.

[0049] like Figure 5 As shown, a positioning block 303 is slidably fitted inside the auxiliary positioning post 301. The positioning block 303 and the compression limiting block 305 work together to assist in positioning the battery bracket 101.

[0050] like Figure 5 As shown, a positioning cylinder 304 is fixedly connected to the side of the auxiliary positioning column 301 close to the clamping base 201. The telescopic end of the positioning cylinder 304 is fixedly connected to the positioning block 303. By controlling the movement of the telescopic end of the positioning cylinder 304, the positioning block 303 is moved synchronously, thereby controlling the positioning and clamping state of the positioning block 303 and the compression limiting block 305. The compression limiting block 305 is arranged below the positioning block 303 and is fixedly mounted on the top of the battery bracket 101. The compression engagement between the compression limiting block 305 and the positioning block 303 can limit the connection between the battery bracket 101 and the positioning block 303.

[0051] Specifically, both the locking cylinder 211 and the positioning cylinder 304 are commercially available and can be purchased and used directly. In actual application, they are connected to an external gas control system. The gas control system supplies compressed air to the locking cylinder 211 and the positioning cylinder 304 to control the extension and retraction of their telescopic shafts. This is existing technology and will not be described in detail here.

[0052] It is worth noting that the lower surface of the positioning block 303 and the upper surface of the extrusion limiting block 305 are both inclined towards the side close to the auxiliary positioning post 301. This facilitates improving the extrusion positioning stability of the positioning block 303 and the extrusion limiting block 305.

[0053] like Figures 3 to 4 As shown, multiple evenly distributed auxiliary guide frames 306 are fixedly connected to the battery swapping base 1, and the auxiliary guide frames 306 are arranged between the positioning post 103 and the clamping base 201. The auxiliary guide frames 306 play a role in limiting the assembly of the side guide bearings 307. The side guide bearings 307 are rotatably connected above each of the multiple auxiliary guide frames 306. The rolling of the multiple side guide bearings 307 can guide and limit the battery tray 101. The cooperation of the auxiliary guide frames 306 and the side guide bearings 307 can guide and limit the assembly process of the battery tray 101.

[0054] like Figure 1 As shown, a mounting base 105 is fixedly connected to the middle of the battery bracket 101. The battery terminal electrical connector is assembled and fixed through the mounting base 105.

[0055] like Figures 6 to 7 As shown, a fixed base plate 106 is fixedly connected to the battery swapping base 1 at the position corresponding to the mounting base 105. The fixed base plate 106 supports and fixes multiple sets of supporting pins 308. Multiple sets of evenly distributed supporting pins 308 are fixedly connected to the fixed base plate 106. The socket plate 309 is guided to move up and down through the multiple sets of supporting pins 308.

[0056] like Figures 6 to 7 As shown, a socket plate 309 is inserted and fitted above multiple sets of supporting pins 308. The socket plate 309 limits the insertion of the battery terminal electrical connector.

[0057] like Figures 6 to 7 As shown, springs 310 are fitted on the outer sides of multiple sets of supporting pins 308, and the springs 310 are arranged between the socket plate 309 and the fixed base plate 106. The springs 310 support and limit the socket plate 309, so that the socket plate 309 can be flexibly supported by the contraction or return of the springs 310.

[0058] like Figures 6 to 7 As shown, one end of each set of supporting pins 308 located above the socket plate 309 is threaded with a positioning nut 311. The positioning nut 311 serves to limit the movement of the socket plate 309. Each set of supporting pins 308 has a cotter pin 312 inserted at its top, positioned above the positioning nut 311. The cotter pin 312 serves to prevent the socket plate 309 from dislodging.

[0059] In practical use, when assembling the battery tray 101, a hoisting device is used to lift the battery tray 101 and move it above the battery swapping base 1. The battery tray 101 is then lowered. During the lowering and assembly process, the positioning column 103 and the guide plate 104 work together to position the battery tray 101 and the battery swapping base 1. Simultaneously, the auxiliary positioning column 301, the positioning block 303, the auxiliary guide frame 306, and the side guide bearing 307 work together to guide and limit the battery tray 101.

[0060] After the battery tray 101 is placed above the battery swapping base 1, the drive side plate 203 is driven to rotate around the clamping base 201 by extending the telescopic shaft of the locking cylinder 211. At the same time, the pressure rod 202 moves towards the battery tray 101 under the action of the linkage plate 204, following the movement of the drive side plate 203. The pressure rod 202 drives the locking positioning rod 205 to move, so that the locking head 209 can press and lock the locking block 210.

[0061] Meanwhile, the positioning block 303 can be moved by extending the telescopic end of the positioning cylinder 304. The positioning block 303 can assist in the compression positioning of the battery bracket 101 through the cooperation of the positioning block 303 and the compression limiting block 305.

[0062] When it is necessary to disassemble the battery tray 101, the pressure rod 202 and the positioning block 303 can be pulled and reset by controlling the resetting of the telescopic shaft of the locking cylinder 211 and the resetting of the telescopic end of the positioning cylinder 304, thereby releasing the locking and fixing state of the battery tray 101. Subsequently, the battery tray 101 can be separated from the battery swapping base 1 by lifting the battery tray 101.

[0063] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0064] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
