[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides a battery fixing device for battery testing, including a base 1, a fixed clamp 3 and a movable clamp. The base 1 is L-shaped, and the fixed clamp 3 is fixedly connected to the middle of the top of the horizontal end of the base 1. The fixed clamp 3 divides the base 1 into two parts. When the device is in use, batteries can be placed on both sides of the fixed clamp 3, and the vertical end of the base 1 and the fixed clamp 3 play a positioning function to limit the position of the batteries and facilitate the fixing of the battery position.
[0024] The movable clamp is connected to the base 1 via a transfer structure. The position of the movable clamp can be changed using the transfer structure, so that the movable clamp and the fixed clamp 3 can be used together to clamp and fix the battery placed at one end or the other end of the base 1.
[0025] The transfer structure includes a translation structure connected to the top of the vertical end of the base 1. In some embodiments of this application, the translation structure includes a ball screw 10 movably connected to the top of the vertical end of the base 1. A ball nut is threaded onto the outer ring of the ball screw 10, and a connecting block 4 is fixedly connected to the outer ring of the ball nut. A servo motor 14 is provided on one side of the vertical end of the base 1. The output shaft of the servo motor 14 is fixedly connected to one end of the ball screw 10 through a reducer. With the servo motor 14, the rotation of the servo motor 14 can drive the ball screw 10 fixedly connected to it to rotate. When the ball screw 10 rotates, the ball nut threaded onto it moves in the direction of the ball screw 10. When the ball nut moves, it drives the connecting block 4 connected to it to move.
[0026] In some other embodiments of this application, the translation structure may be an electric telescopic rod in the prior art, with a connecting block 4 fixedly connected to the end of the output shaft of the electric telescopic rod, and the movement of the connecting block 4 is controlled by the telescopic movement of the electric telescopic rod.
[0027] The top of the connecting block 4 is fixedly connected to an electric telescopic rod 15. The electric telescopic rod 15 is connected to the movable clamping plate through a connecting structure. The connecting structure includes a plug 16 fixedly connected to the end of the output shaft of the electric telescopic rod 15, two slots 8 adapted to the plug 16, and a rotating block 7 fixedly connected to the movable clamping plate.
[0028] One side of the insertion block 16 is provided with a movable groove 5. Inside the cavity of the movable groove 5, there is an electromagnet 19 and a spring 18. The other end of the spring 18 is fixedly connected to the insertion rod 17. The insertion rod 17 is movably connected to the cavity of the movable groove 5. When the electromagnet 19 is energized, the electromagnet 19 and the insertion rod 17 are magnetically attracted. The position of the insertion rod 17 can be controlled by the setting of the electromagnet 19. When the electromagnet 19 is energized, under the action of the magnetic attraction between the electromagnet 19 and the insertion rod 17, the insertion rod 17 moves completely into the cavity of the movable groove 5. When the electromagnet 19 is de-energized, under the action of the spring 18, the end of the insertion rod 17 away from the spring 18 moves to the outside of the insertion block 16.
[0029] One side of the inner cavity of the slot 8 is provided with a socket 12 that is adapted to the plug rod 17. When the plug 16 is inserted into the inner cavity of the slot 8, the movable slot 5 and the socket 12 are aligned. By controlling the on and off of the electromagnet 19, the plug 16 and the slot 8 can be quickly separated or connected.
[0030] A servo motor 11 is fixedly connected to the top of slot 8. The output shaft of the servo motor 11 is fixedly connected to the rotating block 7 via a reducer. Rotating blocks 7 are fixedly connected to both sides of the movable clamping plate. With the servo motor 11, when the servo motor 11 rotates, it can drive the rotating block 7 connected to it to rotate. The rotating block 7 can drive the movable clamping plate to rotate, which facilitates the use or transfer of the movable clamping plate.
[0031] The bottom of slot 8 is at the same height as the top of the vertical end of base 1. Electromagnet 2 13 is provided at the bottom of slot 8. During the transfer of the movable clamping plate, slot 8 contacts the top of the vertical end of base 1. When electromagnet 2 13 is energized, electromagnet 2 13 is magnetically attracted to the vertical end of base 1. The position of movable clamping plate can be fixed by setting electromagnet 2 13, which makes it easy for plug 16 to be connected to different slots 8.
[0032] As described above, when using this device, the position of the movable clamp can be changed by the transfer structure. The cooperation between the movable clamp and the fixed clamp can clamp and fix the battery. Two batteries can be placed on the base 1 at the same time. When the tested battery is removed, the device can clamp and fix another battery to be tested, eliminating the time waiting for battery replacement, improving battery fixing efficiency, and thus improving battery testing efficiency.
[0033] A baffle plate 2 is fixedly connected to the outer side of the top of the vertical end of the base 1. The baffle plate 2 and the vertical end of the base 1 form a cavity. The transfer structure is set in the cavity. The movable clamp is adapted to the cavity. During the transfer process, the movable clamp moves in the cavity. By setting the baffle plate 2, the transfer structure and the movable clamp can be blocked, which facilitates the use of the transfer structure and the movement of the movable clamp.
[0034] To reduce the space occupied by the movable clamping plate during rotation, the movable clamping plate is designed as a telescopic structure. The movable clamping plate includes a plate body 6, and two adjacent plate bodies 6 are connected by an electric telescopic rod 9. The extension and retraction of the electric telescopic rod 9 can change the position of the plate body 6 connected to it, thereby realizing the extension and retraction of the movable clamping plate. Preferably, the bottom of the movable clamping plate is at the same height as the top of the vertical end of the base 1.
[0035] Pressure sensors 20 are provided on both sides of the fixed clamping plate 3 and both sides of the movable clamping plate. The pressure sensors 20 can be used to detect the clamping force of the device on the battery, thereby improving the safety of the device.
[0036] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.
[0037] The present application will be further described below through an embodiment.
[0038] In this embodiment, the position of the movable clamp is as follows: Figure 1 As shown, when using this battery fixing device for battery testing, the user places the battery to be tested on the top left side of the horizontal end of the base 1, with the battery in contact with both the fixing clamp 3 and the vertical end of the base 1. Servo motor 11, located near the fixing clamp 3, rotates, causing the connected rotating block 7 to rotate 90 degrees. At this time, the movable clamp and the fixed clamp 3 are parallel to each other. Servo motor 14 then rotates the connected ball screw 10. The rotation of the ball screw 10 causes the threaded ball nut to move in the direction of the ball screw 10. The ball nut, through the connected connecting block 4, moves the electric telescopic rod 15. The electric telescopic rod 15, through the insert block 16 and the slot 8 connected to the insert block 16, moves the movable clamp, which gradually approaches the battery. The combined use of the movable clamp and the fixed clamp 3 achieves the clamping and fixing of the battery.
[0039] During the battery testing process, the user can place another battery to be tested on the top right side of the horizontal end of the base 1, with the other battery in contact with both the fixing plate 3 and the vertical end of the base 1. After the battery test is completed, servo motor 14 drives ball screw 10 to move in the opposite direction. After contacting the movable clamp plate and squeezing the battery, electric telescopic rod 9 retracts, reducing the area occupied by the movable clamp plate. Servo motor 11 drives the movable clamp plate to rotate 90 degrees in the opposite direction. At this time, the movable clamp plate and the fixed clamp plate are in a mutually perpendicular state. The translation structure works, driving the movable clamp plate to move. When the slot 8 on the left side of the movable clamp plate contacts the vertical end of the base 1, the translation structure stops working. Electromagnet 13 on the slot 8 on the left side of the movable clamp plate is energized, fixing the position of the movable clamp plate. Electromagnet 19 is energized. Under the action of the magnetic attraction between electromagnet 19 and the insertion rod 17, the insertion rod 17 moves into the inner cavity of the movable slot 5, separating the insertion rod 17 from the insertion hole 12. Electric telescopic rod 15 retracts until the insertion block 16 is located on the right side of the movable clamp plate. The slot 8 is separated, and the translation structure moves in the opposite direction until the plug 16 and the slot 8 away from the plug 16 are aligned. The electric telescopic rod 15 extends and drives the plug 16 to move until the plug 16 is inserted into the cavity of the slot 8 located on the left side of the movable clamping plate. The electromagnet 19 is de-energized, and under the action of the spring 18, the plug rod 17 is inserted into the socket 12, realizing the connection between the plug 16 and the slot 8 located on the left side of the movable clamping plate. The translation structure continues to drive the movable clamping plate to move until the slot 8 located on the left side of the movable clamping plate moves to the right side of the other battery. The servo motor 11 located on the left side rotates and drives the movable clamping plate to rotate until the movable clamping plate and the fixed clamping plate 3 are in a parallel state. The movable clamping plate is reset, and the translation structure drives the movable clamping plate to move. The cooperation of the movable clamping plate and the fixed clamping plate 3 can realize the fixation of the other battery.
