[0031] like Figures 1 to 4 As shown, the utility model provides a battery PACK test cable disconnecting device, which includes a mounting seat 1, a movable plate 4 and a driving member 7. The mounting seat 1 is provided with a sliding groove, in which a plurality of first strong conductive blocks 2 and a plurality of first weak conductive blocks 3 are provided; the movable plate 4 slides in the sliding groove, and the movable plate 4 faces a second strong conductive block 5 corresponding to the first strong conductive block 2 and a second weak conductive block 6 corresponding to the first weak conductive block 3 in the sliding groove; the first strong conductive block 2 and the second strong conductive block 5 are configured to connect a strong current cable, and the first weak conductive block 3 and the second weak conductive block 6 are configured to connect a weak current cable; the output end of the driving member 7 can abut against or move away from the movable plate 4, when the driving member 7 abuts against the movable plate 4, the second strong conductive block 5 docks with the first strong conductive block 2, and the second weak conductive block 6 docks with the first weak conductive block 3; when the driving member 7 moves away from the movable plate 4, the second strong conductive block 5 can be separated from the first strong conductive block 2, and the second weak conductive block 6 can be separated from the first weak conductive block 3.

[0032] Through the above device, the strong current cables are connected to the first strong conductive block 2 and the second strong conductive block 5 respectively, and one of the test equipment and the battery to be tested is connected to the first strong conductive block 2, and the other is connected to the second strong conductive block 5; similarly, the weak current cables are connected to the first weak conductive block 3 and the second weak conductive block 6 respectively, and one of the test equipment and the battery to be tested is connected to the first weak conductive block 3, and the other is connected to the second weak conductive block 6; when testing, it is only necessary to drive the moving plate 4 to slide in the sliding groove so that the first strong conductive block 2 contacts the second strong conductive block 5 and the first weak conductive block 3 contacts the second weak conductive block 6 to complete the path docking, that is, the driving member 7 provides the resisting force; and when an emergency occurs, there is no need to untie the strong current cable or the weak current cable, it is only necessary to move the driving member 7 away from the above-mentioned moving plate 4 so that the moving plate 4 loses the above-mentioned resisting force, and then the moving plate 4 can slide in the opposite direction in the sliding groove again to disengage the corresponding first strong conductive block 2 and the second strong conductive block 5, and the corresponding first weak conductive block 3 and the second weak conductive block 6, so as to complete the overall disconnection, thereby saving the disconnection time.

[0033] like Figure 1 As shown, in some embodiments, the mounting base 1 includes a base plate 11, and the base plate 11 is provided with a plurality of side baffles 12. The plurality of side baffles 12 and the base plate 11 enclose a sliding groove with an opening, and the movable plate 4 moves between the plurality of side baffles 12, so as to limit the movable plate 4 through the side baffles 12 to prevent it from shifting, thereby ensuring the accuracy of docking. It should be noted here that the number and shape of the side baffles 12 are not specifically limited. Furthermore, a plurality of side baffles 12 are arranged on two opposite sides of the movable plate 4, and the plurality of side baffles 12 are arranged at intervals along the edge of the movable plate 4, so that a gap is formed between the adjacent side baffles 12 on the same side of the movable plate 4, so as to facilitate the routing of the strong current cable and the weak current cable. Furthermore, in some embodiments, a mounting plate 13 is also provided on the base plate 11, and the side baffle 12 surrounds and clamps the mounting plate 13 to restrict and fix the mounting plate 13, and the first strong conductive block 2 and the first weak conductive block 3 are provided on the mounting plate 13, so that according to different test conditions, the first strong conductive block 2 and the first weak conductive block 3 can be replaced by using the detachable mounting plate 13, avoiding replacement of the entire mounting seat 1.

[0034] It should be noted here that if Figure 2 and Figure 3 As shown, the first strong conductive block 2, the first weak conductive block 3, the second strong conductive block 5 and the second weak conductive block 6 need to have a certain thickness, current-bearing cross-sectional area and pressure resistance to avoid being squeezed and damaged during contact. At the same time, the number is not specifically limited, and their distribution must ensure an electrically safe gap.

[0035] like Figure 1As shown, in some embodiments, since the operator still needs to manually drive the moving plate 4 to move in the reverse direction when disconnecting, that is, to pull up the moving plate 4, so that the first strong conductive block 2, the first weak conductive block 3, the second strong conductive block 5 and the second weak conductive block 6 are disconnected, based on the above manual form, the side of the moving plate 4 away from the first strong conductive block 2 is provided with a handle 41, so that it is convenient for the operator to carry it by hand, and it is more convenient to disconnect. In other embodiments, in order to facilitate automatic operation, an elastic member (not shown in the figure) is connected between the mounting seat 1 and the moving plate 4, so that when the moving plate 4 moves to connect the first strong conductive block 2, the first weak conductive block 3, the second strong conductive block 5 and the second weak conductive block 6, the above elastic member can be squeezed, and when disconnected, the restoring force of the elastic member can be relied on to move the moving plate 4 away in the reverse direction, so as to achieve the disconnection of the first strong conductive block 2, the first weak conductive block 3, the second strong conductive block 5 and the second weak conductive block 6. Exemplarily, the elastic member can be a compression spring or an elastic rubber.

[0036] like Figure 1 and Figure 4 As shown, in order to facilitate the driving member 7 to abut the moving plate 4 more smoothly, in some embodiments, a pressing block 71 is provided at the output end of the driving member 7, and the driving member 7 can drive the pressing block 71 to abut the side of the moving plate 4 away from the second strong conductive block 5, thereby abutting the moving plate 4 to move in the sliding groove to achieve connection; and when disconnection is required, it is only necessary to drive the pressing block 71 away from the moving plate 4, and then the moving plate 4 can be operated to move in the opposite direction, thereby facilitating the breaking operation. Further, in order to make the force on the moving plate 4 uniform, a plurality of driving members 7 can be provided, and each driving member 7 is correspondingly provided with a pressing block 71, and the plurality of driving members 7 are evenly distributed along the moving plate 4. Furthermore, a control switch 10 is also provided on the mounting seat 1, and the control switch 10 is communicatively connected with the controllers of the plurality of driving members 7, so that the driving member 7 is controlled by the control switch 10, saving operation time.

[0037] In some embodiments, the driving member 7 is linearly driven, and the driving member 7 drives the above-mentioned pressing block 71 to move in a direction perpendicular to the moving direction of the moving plate 4, that is, a side pressure type is adopted. Compared with the traditional unidirectional type, this method reduces the volume of the entire device, thereby facilitating wall-mounting fixation. Furthermore, due to the adoption of the side pressure type, when the pressing block 71 is close to the moving plate 4, in order to avoid the two from contacting and getting stuck, a chamfer is set on the edge of the pressing block 71, so that the pressing block 71 and the moving plate 4 are slidably abutted through the chamfer to avoid the above-mentioned jamming phenomenon. Exemplarily, in the current embodiment, the driving member 7 adopts an electric push rod. Compared with the transmission cylinder, the electric push rod does not require an air source and has stronger stability.

[0038] like Figure 1 and Figure 2As shown, in some embodiments, a temperature control switch 8 is provided on the mounting base 1, and the temperature control switch 8 is provided on the side of the first strong conductive block 2 on the mounting base 1, so as to monitor the contact temperature of the first strong conductive block 2 and the second strong conductive block 5, avoid heating of the contacts due to poor contact, and reduce the risk of accidents. Exemplarily, the temperature control switch 8 is provided on the mounting plate 13 on the mounting base 1. In other embodiments, the temperature control switch 8 can also be provided on the moving plate 4. Of course, it can be understood that the above-mentioned temperature control switch 8 can be provided on both the mounting base 1 and the moving plate 4.

[0039] like Figure 1 As shown, further, an alarm 9 is also provided on the mobile plate 4, and the temperature control switch 8 is connected to the alarm 9 in communication, so that when the temperature control switch 8 detects the contact temperature threshold of the first strong conductive block 2 and the second strong conductive block 5, an alarm can be issued to remind the operator. Exemplarily, the alarm 9 can be an audible and visual alarm 9.

[0040] Therefore, the battery PACK test cable disconnecting device can achieve quick disconnection and reduce the time required for disconnection.

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
