Description

Technical Field

[0001] The utility model belongs to the technical field of storage batteries, and in particular relates to a battery detection and power connection device. Background Art

[0002] Batteries are devices that convert chemical energy directly into electrical energy. To ensure proper function, batteries must be tested using a power connection device before shipment and packaging. This testing requires first connecting the device's measuring plate to the positive and negative poles of a test light via wires. The battery's two conductive contacts are then brought into contact with the device's two measuring plates. However, existing testing devices lack the ability to adjust the position of the measuring plates, limiting their practicality to only batteries with fixed contact points.

[0003] The existing patent, CN218584851U, discloses a battery detection and connection device, which is equipped with a base plate, side plates, a transverse block, a connection rod, locking screws, a push handle, an indicator tip, a connecting spring, and a support plate. When the battery needs to be connected and tested, the staff first pushes the transverse block to move the connection rod to the appropriate position, and then uses the locking screw to connect the pole to the limit and fix it. The push handle is then pulled to align the middle position of the battery with the indicator tip. The push handle is then released, and the elastic action of the connecting spring pushes the battery closer to the connection rod through the support plate, so that the battery connection head contacts the connection rod, thus completing the connection test.

[0004] The above solution can be adjusted to the position of the pole, thus adapting to batteries with different connector positions, thereby improving the adaptability and practicality of the device. However, before the battery connector is brought into contact with the pole, the above solution requires aligning the center of the battery with the indicator tip. This alignment step increases the battery detection time. Furthermore, without any restraints, the battery is easily displaced during sliding by simply pushing the support plate, which can affect the battery detection results. This has significant practical limitations. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0023] like Figure 1-Figure 5 As shown, the technical solution adopted by the present invention is as follows: a battery detection and power connection device, comprising a base plate 1, a vertical side plate 13 fixed on the top of the base plate 1, two transverse slots 12 symmetrically provided in the horizontal direction in the side plate 13, and a metal rod 9 fixed in each transverse slot 12. The facing ends of the two metal rods 9 are fixedly connected to the inner wall of the transverse slot 12, and the opposite ends of the two metal rods 9 extend to the outside of the side plate 13 and are threaded with a locking nut 10. The metal rod 9, the power connection rod 11 and the second slider 16 are all made of conductive metal. When in use, one end of the wire fixedly connected to the external test lamp can be wound around the end of the metal rod 9, and the locking nut 10 is rotated to fix it (the test lamp and the wire are both drawn in the figure).

[0024] A second slider 16 is provided in each of the two transverse slots 12 for limited sliding movement. The second sliders 16 correspond one-to-one to the metal rods 9, and each second slider 16 is slidably mounted on the corresponding metal rod 9. A connecting rod 11 is fixedly provided at one end of each of the two second sliders 16, and both connecting rods 11 are slidably connected to the side panels 13. At the same time, the side panels 13 are also provided with fasteners for limiting the position of the connecting rods 11, specifically locking bolts 15. Threaded holes are provided at the ends of the two second sliders 16 that are not connected to the connecting rods 11, and the locking bolts 15 are threadedly engaged with the threaded holes. By rotating and screwing in the locking bolts 15, the connecting rods 11 are fixed in position.

[0025] A first chute 3 is defined at the top of the base plate 1. A third slider 23 is positioned within the first chute 3 for limited sliding movement. The third slider 23 moves toward or away from the side plate 13. A first spring 2 is fixedly disposed between the third slider 23 and the first chute 3. The first spring 2 extends and contracts in the same direction as the sliding direction of the third slider 23. One end of the first spring 2 is fixedly connected to the inner wall of the first chute 3, and the other end is fixedly connected to the third slider 23.

[0026] A supporting plate 14 is fixedly provided on the top of the third slider 23 , and the supporting plate 14 is slidably matched with the bottom plate 1 . The supporting plate 14 and the side plate 13 are arranged facing each other. The handle 6 is fixedly installed on the side of the supporting plate 14 away from the side plate 13 , and two fixed shells 19 are slidably provided on the side of the supporting plate 14 close to the side plate 13 .

[0027] Two second chute grooves 8 are symmetrically positioned within the support plate 14. A first slider 7 is positioned within each second chute 8 for limited sliding movement. The two first sliders 7 slide toward or away from each other. A bidirectional screw rod 5 is positioned within the support plate 14 for horizontal rotation. Both sides of the bidirectional screw rod 5 are rotatably connected to the base plate 1. The two first sliders 7 correspond one-to-one with the two threaded sections of the bidirectional screw rod 5, and each first slider 7 is threadedly engaged with the corresponding threaded section. Simultaneously, the two first sliders 7 are fixedly connected to the two fixed shells 19 in a one-to-one correspondence. Each fixed shell 19 is slidably connected to a support rod 21 via an elastic member. The two support rods 21 are symmetrically positioned, facing each other.

[0028] The elastic member is specifically a second spring 20. A retaining rod 21 is provided within each fixed housing 19 for limited sliding movement. One end of the second spring 20 is fixedly connected to the retaining rod 21, and the other end of the second spring 20 is fixedly connected to the inner sidewall of the fixed housing 19. Simultaneously, the facing ends of the two retaining rods 21 slide through the fixed housing 19 in which they are located. Each retaining rod 21 is provided with a stopper at each end to prevent the retaining rod 21 from separating from the fixed housing 19.

[0029] In addition, the support plate 14 is in transmission cooperation with the bidirectional screw 5. A placement groove 22 is provided in the support plate 14, and a second gear 18 is provided in the placement groove 22 through a horizontal rotation of a rotating shaft, and both ends of the rotating shaft are rotatably connected to the support plate 14. A first gear 17 is coaxially fixed on the outer surface of the bidirectional screw 5, and the first gear 17 and the second gear 18 are meshed and transmitted and always remain in a meshed state. A rack 4 is fixedly provided on the top of the base plate 1 along the sliding direction of the third slider 23, and the second gear 18 is meshed and transmitted and always remains in a meshed state. At the same time, a clearance groove is also provided on the support plate 14, and the clearance groove is used to prevent the rack 4 from affecting the movement of the support plate 14.

[0030] Working Principle: Initially, the second spring 20 is compressed, and the two supporting rods 21 are in contact with each other. During operation, wires are connected to the ends of the two metal rods 9 located outside the side plate 13. The wires are secured to the ends of the metal rods 9 located outside the side plate 13 using the locking nuts 10. The two wires are then connected to the positive and negative terminals of an external test light (the wires and test light are not shown). Next, the second slider 16 is moved appropriately to adjust the position of the power supply rod 11 according to the actual battery connector position, and the locking bolt 15 is tightened.

[0031] Pulling handle 6 causes the abutment plate 14 to slide away from the side plate 13, thereby compressing the first spring 2. Simultaneously, the meshing transmission between rack 4 and second gear 18 causes the second gear 18 to rotate as the abutment plate 14 slides. This in turn drives the bidirectional screw 5 via first gear 17. This rotation of the bidirectional screw 5 causes the two first sliders 7 to slide away from each other, causing the two fixed housings 19 to slide away from each other.

[0032] like Figure 4 As shown, when the two fixed shells 19 begin to slide, the two abutting rods 21 do not slide, and the second spring 20 gradually rebounds. When the fixed shells 19 abut against the limit blocks of the abutting rods 21 located inside the fixed shells 19, as the fixed shells 19 continue to move, the two fixed shells 19 will drive the two abutting rods 21 away from each other until the distance between the two abutting rods 21 is greater than the length of the battery.

[0033] Then, the battery is placed on top of the bottom plate 1 and between the two abutting rods 21 , and the abutting plate 14 is released. At this time, under the elastic action of the first spring 2 , the abutting plate 14 pushes the battery to slide toward the side plate 13 .

[0034] During this process, the second gear 18 rotates in the opposite direction, thereby driving the bidirectional screw 5 in the opposite direction via the first gear 17. The bidirectional screw 5 then drives the two first sliders 7 toward each other, which in turn drives the two fixed housings 19 toward each other. As the two fixed housings 19 approach each other, they clamp and limit the battery and achieve centering alignment. The second spring 20 acts as a buffer during this clamping process.

[0035] When the battery connection head contacts the connection pole 11, the connection detection work is completed.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
