[0031] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0032] Example 1

[0033] refer to Figure 1 As shown, an embodiment of the present application provides a battery limiting tool 100 , which includes a base 110 , a guide assembly 120 , an adjustment assembly 130 and a positioning assembly 140 .

[0034] Specifically, combined Figure 1 and Figure 2As shown, the guide assembly 120 is mounted on the base 110, and an opening 121 is opened at one end of the guide assembly 120; the adjustment assembly 130 is arranged in the opening 121, and the adjustment assembly 130 is movably connected to the guide assembly 120 and defines a guide space 150 with the guide assembly 120; the positioning assembly 140 is arranged in the guide space 150, and the positioning assembly 140 is slidably connected to the guide assembly 120, and the positioning assembly 140 defines a plurality of battery slots 141. Accordingly, the guide assembly 120 is mounted on the base 110, and the adjustment assembly 130 is arranged in the opening 121. The component 130 and the guide component 120 together form a guide space 150, and a positioning component 140 is installed in the guide space 150. The battery 200 can be placed in the battery slot 141 of the positioning component 140. The positioning component 140 is slid relative to the guide component 120 by adjusting the component 130 to press the positioning component 140, so as to press and limit the battery 200 in the battery slot 141. Since the gas in the battery 200 is not discharged, the shape of the battery 200 is prevented from being deformed when the battery 200 is subjected to the negative pressure formation process, thereby achieving the purpose of restraining the shape of the battery 200.

[0035] Understandably, during the negative pressure formation process, the electrochemical reaction inside the battery generates gas. This gas cannot be discharged promptly in a negative pressure environment, causing internal pressure to increase and, in turn, deformation of the battery casing. While ensuring that the battery casing does not deform, the gas discharge passage inside the battery can be kept unobstructed, allowing the gas to be discharged promptly.

[0036] refer to Figure 1 and Figure 2 As shown, the battery positioning fixture 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X is taken as the length direction of the battery positioning fixture 100, the second direction Y is taken as the width direction of the battery positioning fixture 100, and the third direction Z is taken as the height direction of the battery positioning fixture 100. It will be understood that the above definitions are merely for the purpose of facilitating the understanding of the relative positional relationships of the various components of the battery positioning fixture 100 and should not be construed as limiting this application.

[0037] In one embodiment, optionally, Figure 1As shown, the positioning assembly 140 includes a plurality of limit plates 142 and a plurality of side plates 143. The plurality of limit plates 142 are spaced apart along the first direction X, and the adjacent limit plates 142 are respectively connected to the side plates 143 to form the battery slot 141. Accordingly, the side plates 143 and the limit plates 142 are enclosed to form the battery slot 141. The battery slot 141 is used to place the battery 200, so that the battery 200 in the battery slot 141 is compressed and restrained under the action of the adjustment assembly 130 to avoid deformation of the shape of the battery 200.

[0038] In one embodiment, optionally, in combination Figure 2 and Figure 3 As shown, the guide assembly 120 is provided with a slide rail member 122, and the positioning assembly 140 is provided with a connecting member 145, so that the positioning assembly 140 is slidably connected to the slide rail member 122 through the connecting member 145. Accordingly, the positioning assembly 140 can move relative to the slide rail member 122 along the first direction X through the connecting member 145, and the adjustment assembly 130 abuts and presses the positioning assembly 140, so that the positioning assembly 140 is limited and restrained under the joint action of the adjustment assembly 130 and the guide assembly 120.

[0039] In one embodiment, optionally, reference Figure 2 As shown, the adjustment assembly 130 includes a first adjustment plate 131, a second adjustment plate 132 and an adjustment member 133. The first adjustment plate 131 and the second adjustment plate 132 are arranged opposite to each other, and the second adjustment plate 132 is connected to the positioning assembly 140 on the side away from the first adjustment plate 131. The first adjustment plate 131 is provided with a mounting hole, and the adjustment member 133 is passed through the mounting hole and abuts against the second adjustment plate 132, and the adjustment member 133 is threadedly connected to the mounting hole. Accordingly, the adjustment member 133 connects the first adjustment plate 131 and the second adjustment plate 132. The adjustment member 133 can adjust the distance between the first adjustment plate 131 and the second adjustment plate 132 so that the second adjustment plate 132 presses the positioning assembly 140.

[0040] In summary, the guide component 120 of the battery limiting tool 100 is installed on the base 110, and the adjustment component 130 and the guide component 120 together form a guide space 150. The positioning component 140 is installed in the guide space 150, and the battery 200 can be placed in the battery slot 141 of the positioning component 140. The positioning component 140 is slid relative to the guide component 120 by the adjustment component 130 to press the positioning component 140, so as to press and limit the battery 200 in the battery slot 141. Since the gas in the battery 200 is not discharged, the shape of the battery 200 is prevented from being deformed when the battery 200 is subjected to the negative pressure formation process, thereby achieving the purpose of restraining the shape of the battery 200, so that the gas in the battery 200 can be better discharged in subsequent processes.

[0041] Example 2

[0042] refer to Figures 1 to 3 As shown, an embodiment of the present application provides another battery limiting tool 100 , which includes a base 110 , a guide assembly 120 , an adjustment assembly 130 and a positioning assembly 140 .

[0043] Specifically, combined Figure 1 and Figure 2 As shown, the guide assembly 120 is mounted on the base 110, and an opening 121 is formed at one end of the guide assembly 120. The adjustment assembly 130 is disposed in the opening 121 and is movably connected to the guide assembly 120, defining a guide space 150 with the guide assembly 120. The positioning assembly 140 is disposed in the guide space 150 and is slidably connected to the guide assembly 120. The guide assembly 120 is mounted on the base 110, and the adjustment assembly 130 and the guide assembly 120 together form the guide space 150, within which the positioning assembly 140 is mounted.

[0044] In this embodiment, the positioning component 140 defines a plurality of battery slots 141. Accordingly, the battery 200 can be placed in the battery slot 141 of the positioning component 140. The positioning component 140 is slid relative to the guide component 120 by adjusting the component 130 to press the positioning component 140, so as to press and limit the battery 200 in the battery slot 141. Since the gas in the battery 200 is not discharged, the shape of the battery 200 is prevented from being deformed when the battery 200 is subjected to the negative pressure formation process, thereby achieving the purpose of restraining the shape of the battery 200.

[0045] refer to Figure 1 and Figure 2As shown, the battery retaining fixture 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicular to each other. For example, the first direction X is the length direction of the battery retaining fixture 100, the second direction Y is the width direction of the battery retaining fixture 100, and the third direction Z is the height direction of the battery retaining fixture 100.

[0046] In one embodiment, optionally, Figure 1 As shown, the positioning assembly 140 includes a plurality of limit plates 142 and a plurality of side plates 143. The plurality of limit plates 142 are spaced apart along the first direction X, and the adjacent limit plates 142 are respectively connected to the side plates 143 to form the battery slot 141. Accordingly, the side plates 143 and the limit plates 142 are enclosed to form the battery slot 141. The battery slot 141 is used to place the battery 200, so that the battery 200 in the battery slot 141 is compressed and restrained under the action of the adjustment assembly 130 to avoid deformation of the shape of the battery 200. Furthermore, the height of the groove depth of the battery slot 141 is H, and the height of the battery 200 is h, where the height h of the battery 200 refers to the length of the battery 200 along the third direction Z, satisfying: 0.7h≤H<h. In other words, the height H of the groove depth of the battery slot 141 is less than the height h of the battery 200, so that the battery 200 can be placed in the battery slot 141 and the battery 200 is at least partially exposed outside the battery slot 141, so that the battery 200 can be removed from the battery slot 141. In addition, the height H of the groove depth of the battery slot 141 is greater than or equal to 0.7h, so that the battery slot 141 can better limit and restrain the battery 200 in the battery slot 141, preventing the battery 200 from generating gas and causing deformation of the appearance.

[0047] Optionally, refer to Figure 1 As shown, the limiting plate 142 is provided with a protective pad 144, which abuts against the battery 200. The protective pad 144 is used to protect the battery 200 in the battery slot 141. The protective pad 144 has a certain degree of elasticity, so that the protective pad 144 produces elastic deformation to limit and protect the battery 200, thereby preventing damage to the battery 200 during the restraint process. Exemplarily, the protective pad 144 is a rubber pad that protects the surface of the battery 200 from scratches, thereby maintaining the smoothness of the battery 200 surface. The rubber pad also provides anti-collision and anti-slip properties.

[0048] In one embodiment, optionally, in combination Figure 2 and Figure 3As shown, the guide assembly 120 is provided with a slide rail 122, and the positioning assembly 140 is provided with a connecting member 145, so that the positioning assembly 140 is slidably connected to the slide rail 122 via the connecting member 145. Accordingly, the positioning assembly 140 can move relative to the slide rail 122 along the first direction X via the connecting member 145. The adjustment assembly 130 abuts and presses the positioning assembly 140, so that the positioning assembly 140 is limited and restrained by the combined action of the adjustment assembly 130 and the guide assembly 120. Furthermore, the connecting member 145 is provided with a slider, so that the connecting member 145 is slidably connected to the slide rail 122 via the slider.

[0049] Alternatively, as Figure 1 As shown, the connecting members 145 are provided on the opposite sides of the positioning assembly 140 along the second direction Y, and the sliding rail members 122 are provided on the opposite sides of the guide assembly 120 along the second direction Y. The second direction Y is perpendicular to the first direction X. Accordingly, the sliding rail members 122 are installed on the opposite sides of the guide assembly 120 along the width direction of the battery limiting tool 100, and the connecting members 145 are provided at the corresponding positions of the positioning assembly 140 to facilitate improving the stability of the positioning assembly 140 moving on the sliding rail member 122 through the connecting member 145, so that the adjustment assembly 130 drives the positioning assembly 140 to move along the preset path, thereby preventing the positioning assembly 140 from offsetting during movement.

[0050] Optionally, the connecting member 145 is arranged between the side panel 143 and the slide rail member 122, and the connecting member 145 is installed at the position of the side panel 143 so that the connecting member 145 can support the battery slot 141 formed by the side panel 143 and the limit plate 142, and the connecting member 145 is slidably connected to the slide rail member 122, and the positioning assembly 140 moves relatively along the first direction X through the connecting member 145.

[0051] In one embodiment, optionally, reference Figure 2As shown, the adjustment assembly 130 includes a first adjustment plate 131, a second adjustment plate 132, and an adjustment member 133. The first adjustment plate 131 and the second adjustment plate 132 are arranged opposite each other. The side of the second adjustment plate 132 facing away from the first adjustment plate 131 is connected to the positioning assembly 140. The first adjustment plate 131 has a mounting hole. The adjustment member 133 is inserted into the mounting hole and abuts against the second adjustment plate 132. The adjustment member 133 is threadedly connected to the mounting hole. Accordingly, the adjustment member 133 connects the first adjustment plate 131 and the second adjustment plate 132. The adjustment member 133 can adjust the distance between the first adjustment plate 131 and the second adjustment plate 132 to cause the second adjustment plate 132 to press the positioning assembly 140. Furthermore, the first adjustment plate 131 and the second adjustment plate 132 are arranged parallel to each other, and both the first adjustment plate 131 and the second adjustment plate 132 are arranged along the second direction Y. Exemplarily, the adjusting member 133 is an adjusting screw, which is threadedly connected to the mounting hole to abut against the second adjusting plate 132 , so that the adjusting screw moves relatively along the first direction X, and the adjusting screw presses the positioning assembly 140 through the second adjusting plate 132 .

[0052] Alternatively, as Figure 1 and Figure 2 As shown, the first adjustment plate 131 is fixedly connected to the guide assembly 120, and the first adjustment plate 131 is installed at the opening 121 position, that is, the position of the first adjustment plate 131 is fixed relative to the guide assembly 120, and the first adjustment plate 131 is installed at the opening 121 position of the guide assembly 120, and the second adjustment plate 132 is driven to move by the relative movement of the adjusting screw, so that the second adjustment plate 132 is pressed against the positioning assembly 140.

[0053] Optionally, refer to Figure 2 As shown, the second adjustment plate 132 abuts between one of the limit plates 142 and the adjustment member 133, and the second adjustment plate 132 is arranged parallel to the limit plate 142. Accordingly, when the second adjustment plate 132 abuts against one of the limit plates 142, the second adjustment plate 132 and the limit plate 142 are parallel to each other, and there is sufficient contact area between the second adjustment plate 132 and the limit plate 142. Since adjacent limit plates 142 are connected by side plates 143, the second adjustment plate 132 abuts against the positioning assembly 140 and drives the positioning assembly 140 to move along the first direction X.
