In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0042] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:

[0043] refer to Figures 1 to 3 According to the first aspect of the present application, the fixing device includes a base 100, a pressing structure 200, a fixing structure 300 and an elastic member 400. The base 100 is provided with a mounting groove 120, and the mounting groove 120 is used to install a battery 500. The pressing structure 200 is slidably connected to the base 100. The pressing structure 200 includes a pressing portion 210 and a limiting portion 220 connected to each other. The pressing portion 210 is provided with a guide hole 211 extending along a first direction. The pressing portion 210 is located outside the mounting groove 120. The pressing portion 210 can drive the limiting portion 220 to move synchronously along the first direction so that the limiting portion 220 can enter and exit the mounting groove 120. The fixing structure 300 includes a fixing portion 310 and a guide portion 311 connected to each other. 20, the fixing portion 310 is fixedly connected to the base 100, and the guide portion 320 protrudes from the surface of the fixing portion 310. The guide portion 320 can be inserted into the guide hole 211. The cooperation between the guide portion 320 and the guide hole 211 can provide a guiding effect for the movement of the pressing structure 200, thereby preventing the pressing structure 200 from deviating from the first direction when moving. The elastic member 400 is located in the guide hole 211. Along the first direction, one end of the elastic member 400 abuts against the hole wall of the guide hole 211, and the other end of the elastic member 400 abuts against the guide portion 320. The guide hole 211 can also provide a guiding effect for the direction of the elastic force of the elastic member 400, thereby making the relative sliding between the base 100 and the pressing structure 200 smoother.

[0044] The fixing device has an unlocked state and a locked state. In the unlocked state, the pressing portion 210 abuts against the fixing portion 310, and the limiting portion 220 is accommodated in the base 100, so as to realize the rapid disassembly and assembly between the battery 500 and the base 100. In the locked state, the pressing portion 210 and the fixing portion 310 are disengaged from each other, and the limiting portion 220 protrudes from the groove wall of the mounting groove 120 to be inserted into the first groove 510 on the battery 500, so as to limit the movement of the battery 500 relative to the base 100. The elastic member 400 can provide elastic force for the disengagement of the pressing portion 210 and the fixing portion 310, so as to separate the pressing portion 210 and the fixing portion 310 from each other when no external force is applied, thereby converting from the unlocked state to the locked state, which is beneficial to realize the rapid assembly and fixation of the battery 500.

[0045] Specifically, along the first direction, one end of the elastic member 400 abuts against the hole wall of the guide hole 211, and the other end of the elastic member 400 abuts against the guide portion 320. The guide portion 320 is inserted into the guide hole 211. In the absence of external force, the elastic force provided by the elastic member 400 causes the pressing portion 210 and the fixing portion 310 to separate from each other, and the fixing device remains in a locked state. When the battery 500 needs to be disassembled, a force is applied to the pressing portion 210, and the pressing portion 210 drives the limiting portion 220 to move relative to the base 100 along the first direction, so that the limiting portion 220 is moved relative to the base 100. 220 is accommodated in the base 100, ensuring that the battery 500 will not be hindered by the limiting part 220 when entering and exiting the installation slot 120. After the battery 500 is placed in the installation slot 120, the pressing part 210 is released. Under the action of the elastic member 400, the pressing part 210 drives the limiting part 220 to move synchronously along the first direction, so that the limiting part 220 enters the installation slot 120, that is, the limiting part 220 protrudes outward from the slot wall of the installation slot 120, and the limiting part 220 is inserted into the first groove 510 on the battery 500, thereby limiting the battery 500 from detaching from the installation slot 120.

[0046] It should be noted that, along the first direction, the maximum distance between the pressing part 210 and the fixing part 310 is the stroke of the pressing structure 200. The stroke range of the pressing structure 200 can be between 2 mm and 3 mm. For example, the pressing structure 200 can be set to 2.2 mm. If the stroke of the pressing structure 200 is too large, the compression amount of the elastic part 400 will increase, and pressing will be more laborious. If the stroke of the pressing structure 200 is too small, the pressing touch will not be obvious, and it will be difficult to judge whether it is pressed in place. In addition, the compression amount of the elastic part 400 is small, and the rebound effect is relatively poor.

[0047] In other embodiments, when in the unlocked state, the pressing portion 210 compresses the elastic member 400, and the elastic member 400 is compressed to an incompressible state along the first direction. At this time, the pressing portion 210 and the fixing portion 310 are not in contact with each other, and the limiting portion 220 is accommodated in the base 100, and the base 100 and the battery 500 can be disassembled.

[0048] refer to Figures 1 to 4 In some embodiments, the fixing portion 310 and the guide portion 320 enclose an annular positioning groove 330. Along the first direction, the hole wall of the guide hole 211 can be placed in the annular positioning groove 330 for sliding. The groove wall of the annular positioning groove 330 can guide the hole wall of the guide hole 211. When the fixing device switches between the unlocked state and the locked state, the pressing portion 210 can be placed in the annular positioning groove 330. The axis of the annular positioning groove 330 coincides with the axis of the guide hole 211. The guide portion 320 is inserted into the guide hole 211. The mutual cooperation between the guide portion 320 and the guide hole 211 is beneficial to ensure The pressing portion 210 moves relative to the base 100 along the first direction. It should be understood that the axis center of the annular positioning groove 330 coincides with the axis center of the guide portion 320. The pressing portion 210 is placed in the annular positioning groove 330 and slides therein, which can further improve the concentricity of the guide hole 211 and the guide portion 320, thereby preventing the pressing portion 210 from tilting during pressing, and making the pressing smoother and more labor-saving. At the same time, the groove wall of the annular positioning groove 330 located on the fixing portion 310 can also increase the overall strength of the fixing portion 310, so that the fixing portion 310 as a whole is not easily deformed, thereby extending the service life of the fixing portion 310.

[0049] refer to Figures 2 to 5 In some embodiments, a plurality of first connection parts 340 are provided on the fixing part 310, and a plurality of second connection parts 130 are provided on the base 100. The number of the first connection parts 340 and the second connection parts 130 are equal, and the first connection parts 340 and the second connection parts 130 correspond to each other one by one. The first connection parts 340 and the second connection parts 130 at corresponding positions are plugged into each other. The fixing part 310 includes at least two first connection parts 340, and the fixing part 310 is connected to the base 100 at the first connection parts 340, so as to limit the rotation of the fixing part 310 relative to the base 100, avoid excessive fit between the pressing part 210 and the groove wall of the annular positioning groove 330, and help to ensure the smoothness of the pressing of the pressing part 210.

[0050] It should be noted that the fixing part 310 and the base 100 can be connected by screws. When the screws are screwed, the fixing part 310 can be easily driven to rotate relative to the base 100. The guide part 320 is connected to the fixing part 310. The guide part 320 and the guide part 320 enclose an annular positioning groove 330. The axes of the guide part 320 and the annular positioning groove 330 coincide with each other. The rotation of the fixing part 310 relative to the base 100 will cause the axis of the guide hole 211 to be offset relative to the axis of the guide part 320. Therefore, when switching between the locked state and the unlocked state, the hole wall of the guide hole 211 and the guide part 320, as well as the groove wall of the pressing part 210 and the annular positioning groove 330 are over-fitted, affecting the smoothness of switching between the locked state and the unlocked state.

[0051] In some embodiments, a connecting protrusion 140 is provided at the first connecting portion 340, and a connecting groove 350 is provided at the second connecting portion 130. The connecting protrusion 140 is inserted into the connecting groove 350 to realize the connection between the fixing portion 310 and the base 100. It should be understood that the number of the first connecting portions 340 is at least two, and the second connecting portions 130 and the first connecting portions 340 have the same number. The connection between the first connecting portion 340 and the second connecting portion 130 can limit the rotation of the fixing portion 310 relative to the base 100, which is beneficial to ensure the concentricity between the guide hole 211 and the guide portion 320, and avoid the excessive fit between the hole wall of the guide hole 211 and the guide portion 320. The axis of the guide portion 320 coincides with the axis of the annular positioning groove 330, that is, the concentricity of the guide hole 211 and the annular positioning groove 330 can also be ensured at the same time, and the excessive fit between the hole wall of the guide hole 211 and the groove wall of the annular positioning groove 330 can also be avoided, thereby improving the smoothness of the pressing of the pressing portion 210.

[0052] In some embodiments, a connecting groove 350 is provided at the first connecting portion 340, and a connecting protrusion 140 is provided at the second connecting portion 130. The connecting protrusion 140 is inserted into the connecting groove 350 to realize the connection between the fixing portion 310 and the base 100. It should be understood that the number of the first connecting portions 340 is at least two, and the second connecting portions 130 and the first connecting portions 340 have the same number. The connection between the first connecting portion 340 and the second connecting portion 130 can limit the rotation of the fixing portion 310 relative to the base 100, which is beneficial to ensure the concentricity between the guide hole 211 and the guide portion 320, and avoid the excessive fit between the hole wall of the guide hole 211 and the guide portion 320. The axis of the guide portion 320 coincides with the axis of the annular positioning groove 330, that is, the concentricity of the guide hole 211 and the annular positioning groove 330 can also be ensured at the same time, and the excessive fit between the pressing portion 210 and the groove wall of the annular positioning groove 330 can also be avoided, thereby improving the smoothness of the pressing of the pressing portion 210.

[0053] refer to Figures 2 to 4 In some embodiments, two first connecting parts 340 are provided on the fixing part 310, two second connecting parts 130 are provided on the base 100, the annular positioning groove 330 is located between the two first connecting parts 340, a connecting groove 350 is provided at the first connecting part 340, and a connecting protrusion 140 is provided at the second connecting part 130. The connecting protrusion 140 and the connecting groove 350 can be plugged into each other, and the two first connecting parts 340 and the two second connecting parts 130 cooperate with each other to limit the rotation of the fixing part 310 relative to the base 100, to avoid the large friction between the hole wall of the guide hole 211 and the guide part 320 when the pressing part 210 moves relative to the base 100 along the first direction, and to avoid the large friction between the pressing part 210 and the groove wall of the annular positioning groove 330, so that the pressing of the pressing part 210 is more labor-saving and smooth.

[0054] refer to Figures 4 to 6 In some embodiments, a plurality of first connection portions 340 are provided on the fixing portion 310, the limiting portion 220 and at least one of the first connection portions 340 are both located on the side of the pressing portion 210 facing the battery 500, the projections of the limiting portion 220 and the first connection portion 340 along the first direction are staggered with each other, the direction of the pressing structure 200 toward the battery 500 is taken as the second direction, the line connecting the first connection portion 340 and the guide portion 320 is configured to form a first angle a with the second direction, the line connecting the pressing portion 210 and the limiting portion 220 is configured to form a second angle b with the second direction, and the value range of the first angle a can be 20° to 30°, so as to make the first connection portion 340 as close to the position of the guide portion 320 as possible. It should be understood that the pressing part 210 moves along the first direction, and the force borne by the pressing part 210 is transmitted to the guide part 320 through the elastic member 400. The connection between the fixed part 310 and the guide part 320 bears the force applied to the pressing part 210. The first connecting part 340 being close to the guide part 320 is beneficial to improving the bearing capacity of the fixed part 310, increasing the fatigue resistance of the bearing part, and extending the service life of the fixed part 310.

[0055] Specifically, two first fixing portions 310 are provided on the fixing portion 310, and one end of the guide portion 320 connected to the fixing portion 310 is located between the two first fixing portions 310. The fixing portion 310 is connected to the base 100 through two first connecting portions 340, one of the first connecting portions 340 is located on the side of the pressing portion 210 facing the battery 500, and the other first connecting portion 340 is located on the side of the pressing portion 210 away from the battery 500. The connecting line between the first connecting portion 340 located on the side of the pressing portion 210 facing the battery 500 and the pressing portion 210 is configured to have a first angle a with the second direction, and the first angle a can be 29°. Setting it to this angle is beneficial to ensure that the distance between the two first connecting portions 340 is the shortest, thereby improving the bearing capacity of the fixing portion 310. It should be understood that the connecting line between the limiting portion 220 and the pressing portion 210 is configured to have a second angle b with the second direction, so that the projections of the first connecting portion 340 and the limiting portion 220 located on the side of the pressing portion 210 facing the battery 500 along the first direction are staggered from each other, so as to ensure the connection between the first connecting portion 340 located on the side of the pressing portion 210 facing the battery 500 and the base 100, which helps to shorten the distance between the two first connecting portions 340.

[0056] refer to Figures 1 to 7In some embodiments, a protruding structure 110 is provided on the base 100, and the protruding structure 110 surrounds and forms a mounting groove 120. A mounting groove 111 is provided on the protruding structure 110, and the mounting groove 111 is located on the side of the protruding structure 110 away from the mounting groove 120. The pressing portion 210 can slide in the mounting groove 111 along the first direction, and the pressing portion 210 and the battery 500 are separated only by the groove wall of the mounting groove 111. Compared with the case where the mounting groove 111 is not provided, the provision of the mounting groove 111 can reduce the distance between the pressing portion 210 and the battery 500 while ensuring the limiting effect on the battery 500, which is beneficial to the uniform force of the pressing portion 210. It should be understood that the shorter the distance between the pressing portion 210 and the limiting portion 220, the easier it is for the pressing portion 210 to drive the limiting portion 220 to move synchronously along the first direction, which is beneficial to improving the smoothness of the pressing portion 210.

[0057] refer to Figures 2 to 6 In some embodiments, a limiting protrusion 212 is provided on the pressing portion 210, and the limiting protrusion 212 protrudes outward from the side wall of the pressing portion 210. Along the first direction, in the locked state, one side of the pressing portion 210 is supported by the guide portion 320 through the elastic member 400, and the other side of the pressing portion 210 is supported by the base 100 by the limiting protrusion 212 and the limiting portion 220 to limit the separation from the base 100, thereby realizing the sliding connection between the pressing portion 210 and the base 100. Compared with not providing the limiting protrusion 212, providing the limiting protrusion 212 can increase the contact area between the pressing structure 200 and the base 100, so that the mutual supporting force between the pressing structure 200 and the base 100 is more evenly distributed, which is beneficial to extending the service life of the fixing device.

[0058] refer to Figures 6 to 8 In some embodiments, a clamping portion 121 is provided in the mounting groove 120, and the clamping portion 121 protrudes from the side wall of the mounting groove 120. The clamping portion 121 can be clamped into the second groove 520 on the battery 500, so that the limiting portion 220 and the clamping portion 121 jointly limit the battery 500 from being separated from the mounting groove 120. Specifically, the limiting portion 220 is clamped into the first groove 510 on the battery 500, and the limiting portion 220 can limit the battery 500 from being separated from the mounting groove 120 along the third direction.
