[0013] Example
[0014] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0015] The following description, in conjunction with the accompanying drawings, details a lithium-ion battery jack structure provided in this application through specific embodiments and application scenarios.
[0016] refer to Figures 1-2 This application provides a lithium-ion battery jack structure, comprising: a first support member 100 and a second support member 200; preferably, the first support member 100 and the second support member 200 are of the same size and shape to save costs. During use, the surfaces of the first support member 100 and the second support member 200 that contact the workpiece are provided with anti-slip pads, which are either adhered to the first support member 100 and the second support member 200, or injection molded onto them. Silicone pads are preferred for their good wear resistance.
[0017] like Figures 3-4 As shown, a housing 400 and a movable rod 300 are provided between the first support member 100 and the second support member 200. The movable rod 300 has a cylindrical structure, and the housing 400 at least partially encloses the movable rod 300, thus saving the height and volume of the jack structure along the axis of the movable rod 300. The movable rod 300 is fastened to the first support member 100; when the movable rod 300 moves, it drives the first support member 100 to move. An energy body 500, which is a lithium battery pack, is provided outside the housing 400 for plug-in connection. The movable rod 300 is perpendicular to the first support member 100, so that when supporting, the movable rod 300 is subjected to a force parallel to the axis of the movable rod 300, making the movable rod 300 less prone to damage.
[0018] like Figure 3As shown, the housing 300 is provided with a power assembly, the power assembly includes a motor 410, a reducer 420 and a transmission member 440; the motor 410, the reducer 420 and the transmission member 440 are sequentially connected and placed, the energy body 500 provides energy for the motor 410, and the transmission member 440 drives the movable rod 300 to move along the axis of the movable rod 300. One end of the transmission member 440 is provided with a bevel gear, and the other end is provided with a common gear, and the rotation axis of the transmission member 400 is perpendicular to the axis of the movable rod 300. The rotation axis of the transmission member 400 is also perpendicular to the rotation axis of the reducer 420, and here the rotation axis of the reducer 420 is parallel to the axis of the movable rod 300, so that the jack structure is compact, saves volume, and is convenient for transportation.
[0019] As shown in the drawings, Figure 4 The first support 100 and the second support 200 are parallel to each other. The movable rod 300 is provided with a tooth surface 301, and the transmission member 440 is provided with a transmission tooth 441 matched with the tooth surface 301. The transmission tooth 441 meshes with the tooth surface 301 to drive the movable rod 300 to move up and down along the axis of the movable rod 300. In turn, the distance between the first support 100 and the second support 200 is changed, and the function of the jack is played.
[0020] As shown in the drawings, Figures 3-4 The reducer 420 is a planetary gear reducer, when the brake member 421 outside the reducer 420 is controlled to rotate, the transmission function of the reducer 420 can be limited, the brake member 421 has a slot convenient for the insertion of a stop pin 422, when the stop pin 422 is inserted into the slot, the brake member 421 stops rotating. The stop pin 422 also passes through the housing 400, and the movement direction of the stop pin 422 is perpendicular to the reducer output shaft 430.
[0021] The embodiments of the application are described above in combination with the drawings, but the application is not limited to the specific embodiments described above, the specific embodiments described above are only illustrative, not restrictive, and those skilled in the art can make many forms under the inspiration of the application without departing from the purpose of the application and the scope protected by the claims, all of which belong to the protection of the application.
