DETAILED DESCRIPTION

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 3 As shown, the commercial vehicle chassis battery replacement linkage device includes a battery pack 1 and a crossbeam plate 2 located above the battery pack 1. The battery pack 1 is connected to the crossbeam plate 2 through a plurality of fixed locking devices arranged on the side. The upper surface edge of the crossbeam plate 2 is connected with a telescopic device corresponding to the fixed locking device. The crossbeam plate 2 is connected with a linkage mechanism. The linkage mechanism synchronously drives and controls all the telescopic devices to lock the fixed locking device. All the telescopic devices can be synchronously controlled by controlling the linkage mechanism, which greatly improves the overall disassembly and assembly efficiency of the battery pack 1.

[0022] The linkage mechanism includes a plurality of support rods 6 connected to the crossbeam plate 2, the top ends of all the support rods 6 are commonly connected to a support seat 7, an electric cylinder 8 is connected above the support seat 7, a telescopic shaft 9 of the electric cylinder 8 is downwardly connected to a control panel 10, and drives the control panel 10 to rise and fall, and a plurality of control rods 11 are hinged around the periphery of the control panel 10, and the control rods 11 correspond one-to-one to the telescopic devices.

[0023] The electric cylinder 8 drives the control panel 10 to rise and fall through the telescopic shaft 9, so that one end of the control rod 11 connected to the control panel 10 rises and falls, and the other end of the control rod 11 slides back and forth with the rise and fall of the control rod 11, thereby realizing the drive control of the telescopic device. In specific use, due to the different lengths and widths of the battery pack 1, the shape of the control panel 10 and the size of the control rod 11 can be adjusted according to the specific situation. In addition, since the chassis of the commercial vehicle is relatively high and the lower space is relatively large, the setting position of the linkage mechanism can be adjusted and set according to the chassis structure of the commercial vehicle.

[0024] In order to facilitate the fixation of the battery pack 1, the fixing locking device further includes a fixing seat 3 and a fixing platform 4, the fixing seat 3 and the fixing platform 4 are respectively arranged on the sides of the battery pack 1 and the crossbeam plate 2, the fixing platform 4 is connected with a screw 5 through a bearing 16, a locking hole 15 is provided on the upper part of the screw 5, and a threaded hole matching the screw 5 is provided on the fixing seat 3 (not shown in the drawings).

[0025] When the screw 5 is docked with the threaded hole, the helix angle of the thread affects the docking speed. The larger the helix angle, the faster the docking speed. Different helix angles can be set according to actual usage requirements to meet the lifting and lowering of the battery pack 1, that is, to meet the requirements of using the thread to drive the screw 5 to rotate.

[0026] Since the lifting and lowering of the battery pack 1 can drive the screw 5 to rotate, it should be noted that the lifting and lowering of the battery pack 1 is achieved by docking with an external lifting device, and the lifting device is installed on a mobile device such as an AGV trolley. The AGV trolley has a positioning and alignment function to align the lifting device and the battery pack 1 thereon with the screw 5. Therefore, in the locked and fixed state, the screw 5 needs to be positioned and restricted. Further, the telescopic device includes a fixed frame 13, and the fixed frame 13 is fixed to the upper surface edge of the crossbeam plate 2 corresponding to the fixed platform 4. The fixed frame 13 is provided with a through hole at one end close to the fixed platform 4, and a variable diameter slide 20 with an opening upward for placing the control rod 11 at the other end. A pin 18 is placed in the variable diameter slide 20. The pin 18 is connected to the control baffle 12 at one end close to the control rod 11, and the other end passes through the through hole and corresponds to the locking hole 15. A spring 19 is sleeved on the pin 18, and one end of the spring 19 is connected to the control baffle 12, and the other end is connected to the fixed frame 13. After the battery pack 1 is installed in place, the locking hole 15 corresponds to the pin shaft 18, and the electric cylinder 8 drives the control disk 10 to descend through the telescopic shaft 9. The control rod 11 placed on the variable diameter slide 20 will extend outward as the control disk 10 descends, thereby driving the control baffle 12 to move the compression spring 19 and insert the pin shaft 18 into the locking hole 15, thereby locking the screw 5.

[0027] The control baffle 12 can be designed as a convex structure as needed to better match the variable diameter sliding.

[0028] Furthermore, the diameter of the variable diameter slide 20 at one end close to the fixed platform 4 is smaller than the diameter of the end close to the control rod 11. The smaller end can cooperate with the through hole to better limit the movement path of the pin shaft 18, thereby ensuring that it can be accurately inserted into the locking hole 15. At the same time, the larger end can better match the size of the control rod 11.

[0029] Furthermore, a limiting piece 14 is provided on the fixing frame 13 toward the screw rod 5, and a rubber pad 17 is provided on the limiting piece 14 to fit the screw rod 5. The rotation of the screw rod 5 can be limited, so that the auxiliary pin 18 is positioned and inserted into the locking hole 15.

[0030] The entire process of driving the baffle 12 to move is achieved by the end of the control rod 11 contacting it. In order to reduce the friction of the control rod 11 in the variable diameter slide 20 as much as possible, the end of the control rod 11 placed in the variable diameter slide 20 is a hemispherical structure.

[0031] When the utility model is in use: when replacing the battery and installing it, the fixing seat 3 corresponds to the screw rod 5, and the lifting device is used to lift the battery pack 1. The threaded hole matches the screw rod 5 so that the screw rod 5 is rotated and gradually tightened. When the battery pack 1 reaches a predetermined height, the locking hole 15 on the screw rod 5 corresponds to the pin shaft 18. At this time, the electric cylinder 8 is started, and the control disk 10 is driven to move downward through the telescopic shaft 9. Driven by the control disk 10, each control rod 11 slides outward in its corresponding variable diameter slideway 20, pushing the control baffle 12 to move the pin shaft 18 into the locking hole 15 to complete the locking.

[0032] When unloading for battery replacement, the electric cylinder 8 controls the telescopic rod to retract and drive the control disk 10 to move upward. One end of each control rod 11 is lifted, and the other end slides inward in the corresponding variable diameter slideway 20, releasing the restriction on the control baffle 12. The elastic force of the spring 19 causes the control baffle 12 to move inward, driving the pin shaft 18 to move out of the locking hole 15, releasing the lock on the screw 5, and then the battery pack 1 is driven downward by the lifting device, and the screw 5 rotates continuously to realize the disassembly of the screw 5 and the threaded seat, thereby realizing the unloading of the battery pack 1.
