[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 2 As an embodiment provided by the present utility model: An integrated U-shaped busbar includes a busbar main body 1. The shape of the busbar main body 1 is set to be U-shaped. The U-shaped structure helps to maximize the space utilization rate and can withstand a larger current or voltage load at the same time. A foot pad 11 is fixedly connected to the bottom end of the busbar main body 1. The foot pad 11 is used to fix the entire busbar structure to ensure its stability during installation and reliability during use. A plurality of groups of slide grooves 2 distributed in an array are opened on the surface of the busbar main body 1. A plurality of groups of positioning holes 12 distributed in an array are opened on both sides of the slide grooves 2 on the surface of the busbar main body 1. The slide grooves 2 and the positioning holes 12 are used in cooperation, which can realize the flexible configuration of modular components. In this way, users can adjust the positions of the two groups of slide blocks 21 according to needs to adapt to the positions of electrode columns of different types of battery models.

[0032] Refer to Figure 2 - Figure 3Two groups of symmetrically arranged sliders 21 are arranged inside the slide 2. The sliders 21 are arranged in an I-shaped shape. A plug hole 24 is provided on the surface of the slider 21. A positioning pin 13 is slidably connected inside the plug hole 24. The positioning pin 13 is inserted into the inside of the positioning hole 12. The slider 21 is fixed by the cooperation between the positioning pin 13 and the positioning hole 12. The I-shaped slider 21 helps to improve the strength of the slider 21 and keep the slider 21 moving stably in the slide 2. The surfaces of the two groups of sliders 21 are provided with pole connection holes 22. The two groups of pole connection holes 22 are respectively connected to the positive pole and the negative pole of the battery, and the pole connection holes 22 move synchronously with the slider 21 to adjust the position.

[0033] Reference Figure 3 - Figure 4 The inner wall of the pole connection hole 22 is provided with a mounting groove 23, and a fitting component 3 is arranged inside the mounting groove 23. The mounting groove 23 is used to provide a mounting space for the fitting component 3, and the fitting component 3 is used to adapt to battery poles of different sizes. The fitting component 3 includes a movable seat 31, and the movable seat 31 is symmetrically arranged in two groups, and the two groups of movable seats 31 are slidably connected to the inside of the mounting groove 23. The inside of the mounting groove 23 is fixedly connected with a guide rod 32, which penetrates and is slidably connected to the surface of the movable seat 31, and the guide rod 32 is used to provide a guiding function for the two groups of movable seats 31. The ends of the two groups of movable seats 31 are respectively hinged with an inclined plate 33 and an inclined rod 34, and the adjacent ends of the inclined plate 33 and the inclined rod 34 are hinged to each other. The movable seat 31 is elastically connected to the inner wall of the mounting groove 23 through a reset spring 35, and the reset spring 35 is sleeved on the outer wall of the guide rod 32. The return spring 35 provides elastic support for the movable seat 31, so that the two groups of movable seats 31 move toward each other, thereby increasing the inclination angle of the inclined plates 33 and 33. When the battery pole is inserted into the pole connecting hole 22, the inclined plate 33 is squeezed, and under the elastic force of the return spring 35, the inclined plate 33 and the battery pole are tightly fitted together.

[0034] Working principle: During the insertion of the battery pole, the pole first contacts the inclined surface of the inclined plate 33. Due to the inclined setting of the inclined plate 33, the insertion force of the pole changes the angle between the inclined plate 33 and the inclined rod 34, thereby pushing the moving seat 31 to slide to both sides along the guide rod 32. During this process, the return spring 35 is compressed, storing energy for the subsequent fitting action.

[0035] As the pole is further inserted, the angle between the inclined plate 33 and the inclined rod 34 gradually increases until the pole is completely inserted into the pole connection hole 22. At this time, the elastic force of the return spring 35 begins to play a role, pushing the moving seat 31 to slide inward along the guide rod 32 until the inclined plate 33 fits tightly with the battery pole. No matter how big the battery pole is, a good fit can be achieved to ensure stable current transmission.

[0036] In addition, since the slider 21 can move freely in the chute 2 and can be fixed by the cooperation of the positioning pin 13 and the positioning hole 12, the user can flexibly adjust the position of the slider 21 according to the positions of the electrode posts of different models of batteries, so as to achieve compatibility with different models of batteries.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
