They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0025] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] See Figure 1 This application provides a module loading device, including a gripping device and a battery cell module 4. Fixing holes 41 are provided on both opposite sides of the battery cell module 4. The gripping device extends into the fixing holes 41 and abuts against them. In practical applications, the gripping device is inserted into the fixing holes 41, and by abutting against the hole wall, the gripping device and the battery cell module 4 are fixed. Then, the gripping device is used to place the battery cell module 4 into the battery box, completing the module loading process. Since the gripping device is located inside the battery cell module 4, it does not occupy space in the battery box, allowing for a more compact arrangement of multiple battery cell modules 4 within the battery box.

[0028] See Figure 2 and Figure 3 The aforementioned gripping device includes a bracket 1 and a slider 2. The bracket 1 includes a main body 12 and a slide rail 11. The slide rail 11 is disposed on the main body 12 along a first direction. The slider 2 is slidably connected to the slide rail 11. In the direction away from the main body 12, at least part of the cross-section of the slide rail 11 gradually increases. The slide rail 11 is used to extend into the fixing hole 41 of the battery module. The slider 2 is used to abut against the hole wall of the fixing hole 41 together with the slide rail 11.

[0029] To describe clearly, Figure 3 The X direction represents the first direction, which in this embodiment is the vertical direction perpendicular to the horizontal plane.

[0030] In practical applications, firstly, the slider 2 is moved closer to the main body 12. Since the cross-section of the slide rail 11 closer to the main body 12 is smaller, at this position, the combined cross-section of the slide rail 11 and the slider 2 is smaller than the diameter of the fixing hole 41, thus not affecting the slide rail 11's insertion into the fixing hole 41. After the slide rail 11 is inserted into the fixing hole 41, the bracket 1 is lifted away from the battery cell module 4, that is, the slide rail 11 is lifted upwards (away from the fixing hole 41). As the slider 2 slides against the slide rail 11... When the slider 2 moves downward relative to the slide rail 11 (towards the fixing hole 41), the cross-section of the slide rail 11 gradually increases in the direction away from the main body 12. When the slide rail 11 is lifted upward (away from the fixing hole 41), the cross-section at the connection between the slide rail 11 and the slider 2 gradually increases until the cross-section of the slide rail 11 and the slider 2 combined is equal to or greater than the diameter of the fixing hole 41. Then the slider 2 and the slide rail 11 abut against the hole wall of the fixing hole 41, thereby achieving the fixing function of the gripping device and the battery cell module 4.

[0031] Compared with the prior art, the gripping device of this application achieves the contact between the slider 2 and the fixing hole 41 by gradually increasing the cross-section of the slide rail 11. It is only necessary to insert the slide rail 11 into the fixing hole 41 and then pull the bracket 1 to drive the slider 2 to slide until the slider 2 contacts the fixing hole 41. No additional driving components are needed to push the slider 2 to slide, which simplifies the structural design of the device and saves production costs.

[0032] See again Figure 2 The main body 12 includes a horizontal part 121 and a vertical part 122. Vertical parts 122 are provided on opposite sides of the horizontal part 121. Slide rails 11 are connected to the vertical parts 122. The horizontal part 121 has gripping holes 1211. In practical applications, to enhance the connection stability between the gripping device and the battery module 4, multiple slide rails 11 and sliders 2 can be set to abut against the fixing holes 41. Specifically, vertical parts 122 are provided on opposite sides of the horizontal part 121, and each vertical part 122 is connected to a slide rail 11. Multiple slide rails 11 are inserted into the fixing holes 41, and then the bracket 1 is pulled up, causing the sliders 2 on each slide rail 11 to abut against the fixing holes 41. Compared to a single slider 2 abutting against the fixing hole 41, multiple sliders 2 abutting against different fixing holes 41 increases the fixing strength between the gripping device and the battery module 4, preventing the battery module 4 from falling off during transport and damaging the battery quality. The horizontal part 121 has a gripping hole 1211, which facilitates gripping the bracket 1 and moving the bracket 1, thereby moving the cell module 4 into the battery box.

[0033] The main body 12 also includes a reinforcing part 123, which is connected between two vertical parts 122 on opposite sides to increase the structural strength of the support 1.

[0034] See again Figure 2 The gripping device includes a lifting member 3, one end of which is connected to the slider 2, and the other end passes through the main body 12 and is slidably connected to the main body 12.

[0035] In practical applications, the lifting component 3 is used to pull the slider 2 towards the main body 12, preventing the slider 2 from interfering with the slide rail 11 extending into the fixing hole 41. The lifting component can connect multiple sliders 2 simultaneously. For example, one end of the lifting component 3 extends from the vertical part 122 on one side and connects to the slider 2, while the other end extends from the vertical part 122 on the other side and connects to the slider 2. In this way, during operation, only the lifting component needs to be lifted to drive multiple sliders 2 to slide, making operation more convenient. The lifting component 3 can be made of a steel wire rope or similar structure.

[0036] See again Figure 2 The main body 12 also includes a step portion 124. A step portion 124 is formed at the position where the vertical part 122 connects with the slide rail 11. The step portion 124 is used to abut against the slider 2.

[0037] In practical applications, the cross-section of the vertical part 122 is larger than the cross-section of the slide rail 11, so a step part 124 is formed at the position where the vertical part 122 connects with the slide rail 11. When it is necessary to lift the slider 2 towards the main body 12, the step part 124 can prevent the slider 2 from disengaging from the slide rail 11 during the lifting process.

[0038] See again Figure 2 The bracket 1 also includes a limiting member 13, which is connected to the end of the slide rail 11 away from the main body 12. The limiting member 13 is used to prevent the slider 2 from disengaging from the slide rail 11. In practical applications, the limiting member 13 and the step portion 124 work together to prevent the slider 2 from disengaging from the slide rail 11. The step portion 124 restricts the slider 2 from disengaging from the slide rail 11 upwards (away from the fixing hole 41), while the limiting member 13 can restrict the slider 2 from disengaging from the slide rail 11 downwards (closer to the fixing hole 41). Through the combined limiting effect of the limiting member 13 and the step portion 124, a stable connection between the slider 2 and the slide rail 11 can be ensured. The limiting member 13 can be a screw or bolt, etc.

[0039] See Figure 3 The slider 2 is provided with anti-slip grooves 21 at least partially along the first direction. The anti-slip grooves 21 can increase the friction. When the slider 2 abuts against the wall of the fixing hole 41, the anti-slip grooves 21 can significantly increase the friction between the two, which helps to enhance the stability of the slider 2 when abutting and prevent the slider 2 from detaching from the battery module 4.

[0040] See Figure 4 and Figure 5 The slide rail 11 has a first side 111 and a second side 112 opposite to each other. The slider 2 is slidably connected to the first side 111. Along the first direction of the bracket 1, the first side 111 extends at least partially from top to bottom towards the slider 2, and the second side 112 extends vertically from top to bottom.

[0041] In practical applications, in order to facilitate the slide rail 11 to be inserted into the fixing hole 41, the second side 112 of the slide rail 11 extends vertically, that is, the extension direction of the second side 112 is parallel to the extension direction of the fixing hole 41. This facilitates the slide rail 11 to be inserted into the fixing hole 41 and makes it easier for the second side 112 to abut against the hole wall of the fixing hole 41, further increasing the contact between the gripping device and the battery module 4. At the same time, at least part of the first side 111 extends towards the slider 2 along the first direction, which increases the cross-section of the slide rail 11. When the bracket 1 is pulled away from the fixing hole 41, it is easy to abut the slider 2 against the fixing hole 41.

[0042] In one embodiment, along the first direction of the bracket 1, the first side 111 extends obliquely from top to bottom towards the slider 2, and the slider 2 extends vertically from top to bottom. Compared to the above-mentioned first side 111 extending at least partially obliquely, the first side 111 extending obliquely from top to bottom makes the structural transition of the first side 111 smoother, which is beneficial to the smoother sliding of the slider 2. The slider 2 can extend vertically, which allows the slide rail 11 to penetrate into the fixing hole 41 for a longer length, and the slider 2 can slide into the fixing hole 41 to a greater depth, which can increase the connection stability between the gripping device and the battery module 4.

[0043] In one embodiment, along the first direction of the bracket 1, the first side 111 extends obliquely from top to bottom toward the slider 2, and the slider 2 extends obliquely from top to bottom away from the first side 111. In practical applications, the slider 2 can also extend obliquely away from the first side 111, so that when the bracket 1 is lifted, the bracket 1 only needs to be lifted a short distance to make the slider 2 abut against the wall of the fixing hole 41, shortening the stroke of the bracket 1 and saving operating space.

[0044] Unlike existing technologies, this application provides a gripping device and a module loading device. The gripping device includes a support 1 and a slider 2. The support 1 includes a main body 12 and a slide rail 11, which is disposed on the main body 12 along a first direction. The slider 2 is slidably connected to the slide rail 11. At least a portion of the cross-section of the slide rail 11 gradually increases in the direction away from the main body 12. The slide rail 11 is used to extend into the fixing hole 41 of the battery module, and the slider 2 is used to abut against the wall of the fixing hole 41 together with the slide rail 11. Compared to existing technologies, the gripping device of this application achieves the contact between the slider 2 and the fixing hole 41 by gradually increasing the cross-section of the slide rail 11. It only requires extending the slide rail 11 into the fixing hole 41 and then pulling the support 1 to drive the slider 2 to slide until it abuts against the fixing hole 41. No additional driving components are needed to push the slider 2 to slide, simplifying the structural design of the device and saving production costs. The module loading device using this gripping device does not occupy the space of the battery box because the gripping device is located inside the cell module 4, making the arrangement of multiple cell modules 4 in the battery box more compact.

[0045] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
