[0025] Combination Figure 1 and Figure 2 As shown, in one embodiment, the assembly locking device includes: a mounting base 100, a transmission member 200, a cable assembly 300, one or more locking members 400 and one or more elastic return members 500, the transmission member 200 can be movably mounted on the mounting base 100, and the more than one locking members 400 are used to lock and cooperate with the lock hook 10 of the assembly part, the locking members 400 are fixedly arranged on the transmission member 200 at intervals, one end of the elastic return member 500 is in conflict with the locking member 400, and the other end of the elastic return member 500 is in conflict with the mounting base 100, the cable assembly 300 is connected to the transmission member 200, and the cable assembly 300 drives the locking member 400 to move back and forth along the return direction of the elastic return member 500 through the transmission member 200.

[0026] When the assembly locking device is used, first, a mounting base 100 of a corresponding size is selected according to the model or size of the electric vehicle. Then, the transmission member 200 is movably mounted on the mounting base 100. At this time, a corresponding number of locking members 400 are selected according to the number of assembly parts (referring to the assembly parts that need to be locked), and the required locking members 400 are fixedly installed on the transmission member 200 at intervals. In this process, the assembly parts will be affected by the installation position of the electric vehicle. In order to facilitate the locking and matching of each locking member 400 with the corresponding assembly parts, the shape of the transmission member 200 itself can be adjusted accordingly. In addition, setting more than one locking member 400 at intervals can effectively avoid the locking member 400 from conflicting with other assembly parts. Furthermore, one end of the elastic reset member 500 is in contact with the locking member 400, and the other end of the elastic reset member 500 is in contact with the mounting base 100, so that the locking member 400 can effectively ensure the locking effect of the locking member 400 and the lock hook 10 (referring to the lock hook 10 on the assembly part) by using the elastic reset member 500 in the absence of external force, and avoid the accidental separation of the locking member 400 and the lock hook 10. When the staff needs to release the locking and fixing of the locking member 400 and the lock hook 10, they only need to pull the cable assembly 300, and the cable assembly 300 can drive the locking member 400 to move back and forth along the reset direction of the elastic reset member 500 through the transmission member 200, that is, release the locking and fixing of the locking member 400 and the lock hook 10. When the staff removes the external force, the locking member 400 can automatically reset under the action of the elastic reset member 500, that is, the locking member 400 is locked and fixed with the lock buckle again. Therefore, the assembly locking device can simultaneously lock and fix more than one assembly part, making it more convenient to lock and fix the electric vehicle during assembly.

[0027] Combination Figure 1 and Figure 2As shown, in one embodiment, one or more locking members 400 include a first locking tongue member 410 and a second locking tongue member 420, the first locking tongue member 410 and the second locking tongue member 420, and one or more elastic reset members 500 include a first torsion spring 510 and a second torsion spring 520, the first locking tongue member 410 is installed at one end of the transmission member 200, the second locking tongue member 420 is installed at the other end of the transmission member 200, one elastic end of the first torsion spring 510 elastically conflicts with the first locking tongue member 410, the other elastic end of the first torsion spring 510 elastically conflicts with a side of the mounting base 100 close to the first locking tongue member 410, one elastic end of the second torsion spring 520 elastically conflicts with the second locking tongue member 420, and the other elastic end of the second torsion spring 520 elastically conflicts with a side of the mounting base 100 close to the second locking tongue member 420. Specifically, the transmission member 200 is a transmission shaft or a transmission rod. Taking the installation of two battery systems in an electric vehicle as an example, after the two battery systems are installed on the electric vehicle, each battery system is provided with a lock hook 10. At this time, the length of the transmission member 200 and the installation positions of the first lock tongue member 410 and the second lock tongue member 420 on the transmission member 200 are determined according to the installation positions of the two lock hooks 10 on the electric vehicle. The mounting base 100 is installed on the electric vehicle. At this time, the locking cooperation between the first lock tongue member 410 and one of the lock hooks 10 and the locking cooperation between the second lock tongue member 420 and the other lock hook 10 can be achieved through the elastic force of the first torsion spring 510 and the second torsion spring 520. Furthermore, the transmission member 200 can also be a telescopic rod, that is, the length of the transmission member 200 can be flexibly adjusted according to the actual installation situation, thereby improving the applicability of the assembly locking device.

[0028] In one embodiment, the two sides of the mounting base 100 are respectively provided with a first mounting hole and a second mounting hole for the transmission member 200 to pass through, and the two ends of the transmission member 200 pass through the first mounting hole and the second mounting hole respectively. Specifically, the mounting base 100 can be used to limit the installation of the transmission member 200 through the first mounting hole and the second mounting hole. The first mounting hole and the second mounting hole can also be U-shaped holes or bar holes. Further, since the installation positions of the assembled parts change accordingly when different models of electric vehicles are assembled, a plurality of first mounting holes can be set on one side of the mounting base 100 along the horizontal and / or longitudinal direction of the mounting base 100, and a plurality of second mounting holes corresponding to the first mounting holes can be set on the other side of the mounting base 100 along the mounting base 100, so as to facilitate the transmission member 200 to be set on the mounting base 100 in a targeted manner.

[0029] In one embodiment, a first buffer sleeve can be mounted on the first mounting hole, and a second buffer sleeve can be mounted on the second mounting hole. After the transmission member 200 is installed on the mounting base 100, the first buffer sleeve and the second buffer sleeve are both mounted on the transmission member 200, thereby effectively reducing the rotational wear between the transmission member 200 and the mounting base 100.

[0030] In one embodiment, the first torsion spring 510 is sleeved on one end of the transmission member 200, and the first torsion spring 510 is located outside the mounting base 100; the second torsion spring 520 is sleeved on the other end of the transmission member 200, and the second torsion spring 520 is located outside the mounting base 100. Specifically, the above-mentioned assembly method can effectively improve the installation effect of the first torsion spring 510 and the second torsion spring 520 on the assembly locking device. Further, the two elastic ends of the first torsion spring 510 can be straightened and bent again, so that the two elastic ends of the first torsion spring 510 can be fitted and colliding with the first locking tongue member 410 and the mounting base 100. And the two elastic ends of the second torsion spring 520 can be straightened and bent again, so that the two elastic ends of the second torsion spring 520 can be fitted and colliding with the second locking tongue member 420 and the mounting base 100.

[0031] Combination Figure 2 As shown, in one embodiment, a first interfering recess 110 and a second interfering recess 120 are respectively provided on both sides of the mounting base 100, and the first torsion spring 510 elastically interfering with the mounting base 100 through the first interfering recess 110, and the second torsion spring 520 elastically interfering with the mounting base 100 through the second interfering recess 120. Specifically, the first interfering recess 110 and the second interfering recess 120 may be interfering grooves or interfering blocks 330. In this embodiment, when the first torsion spring 510 interferes with the mounting base 100, after the end of the first torsion spring 510 passes through the first interfering recess 110, the first interfering recess 110 can effectively prevent the first torsion spring 510 from accidentally separating from the mounting base 100. When the second torsion spring 520 contacts the mounting base 100 , after the end of the second torsion spring 520 passes through the second contact recess 120 , the second contact recess 120 can effectively prevent the second torsion spring 520 from accidentally separating from the mounting base 100 .

Specifically, the cable assembly 300 is a pull rod or a pull rope. The connecting member 610 is a rod body or a block. The rocker seat 600 can be sleeved and fixed on the transmission member 200, and the connecting member 610 is mounted on the rocker seat 600, and connected to the cable assembly 300 through the connecting member 610. At this time, the force applied to the cable assembly 300 will be transmitted to the rocker seat 600 through the connecting member 610 and finally act on the transmission member 200. The above embodiment transmits force through the rocker seat 600, increases the contact area between the cable assembly 300 and the transmission member 200, and enables the transmission member 200 to rotate more easily with the cable assembly 300. Furthermore, by providing an adjustment port 130 on the mounting base 100, the connecting member 610 extends out of the adjustment port 130, thereby making it more convenient to install the connecting member 610 and the cable assembly 300.

[0033] Combination Figure 1 and Figure 2 As shown, in one embodiment, the assembly locking device further includes a limiting portion 700, the limiting portion 700 is covered on the rocker seat 600, and the two sides of the limiting portion 700 are respectively provided with a first adapter hole and a second adapter hole for the transmission member 200 to pass through. Specifically, the limiting portion 700 is a limiting seat or a limiting frame, and the limiting portion 700 is covered on the rocker seat 600, so that the installation stability of the rocker seat 600 on the transmission member 200 can be improved.

Specifically, the force transmission member 340 is a force transmission rod or a force transmission rope. The force application member 350 is a handle or a rotating wheel. When the force transmission member 340 is connected to the connecting member 610, the force transmission member 340 and the connecting member 610 can be directly welded and fixed, or an assembly hole is opened on the connecting member 610, and one end of the force transmission member 340 passes through the connecting member 610 through the assembly hole and is connected to the abutment block 330, and the abutment block 330 is used to abut against the connecting member 610.
