[0031] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] Combined with reference Figure 1 、 Figure 2 and Figure 3 In the first embodiment of the present application, a battery fixing device is provided for fixing a battery 5, including a first clamping assembly and a second clamping assembly, wherein the second clamping assembly includes a base plate 6 and a clamping block, and the clamping block is arranged on the base plate 6 for clamping a wound battery 5, a laminated battery 5, and a 3C battery 5.

[0033] The first clamping assembly includes a fixed seat 1, an adjusting pin 3 and a clamping piece 2; the fixed seat 1 is arranged on the base plate 6, and the clamping piece 2 is arranged on the fixed seat 1; one end of the adjusting pin 3 is connected to the clamping piece 2, and the other end is connected to the fixed seat 1; a spring ring 31 is sleeved on the adjusting pin 3.

[0034] The outer edge of the clamping member 2 can be curved to better fit cylindrical or button cell batteries 5. Furthermore, the support portion 22 has a certain height to provide support for the battery 5 after placement, preventing displacement. The fixing base 1 is used to hold the battery 5. The clamping member 2 and the fixing base 1 can directly contact the battery 5 and can be made of polyurethane to protect the battery 5 from damage.

[0035] The battery fixing device of this embodiment can fix and clamp the wound battery 5, laminated battery 5, and 3C battery 5 on the bottom plate 6 through the clamping block of the second clamping assembly; it can also be provided with a clamping member 2 on the fixing seat 1 of the first clamping assembly, and the adjustment pin 3 is connected to the clamping member 2. Before clamping the battery 5, the clamping member 2 is stretched open, and the clamping member 2 squeezes the spring coil 31 on the adjustment pin. Then the battery 5 is placed. The spring coil 31 rebounds under the force, and then pushes the clamping member 2 to fit the battery 5, thereby clamping and fixing the cylindrical battery 5 and button battery 5. At the same time, when there is no need to clamp and fix the battery 5, the wound battery 5, laminated battery 5, and 3C battery 5 can be removed from the bottom plate 6 by moving the clamping block; the clamping member 2 can also be stretched open to remove the cylindrical battery 5 and button battery 5. The spring coil 31 pushes the clamping member 2 to clamp and return to its original position through the elastic restoring force, which facilitates the subsequent clamping and fixing of the cylindrical battery 5 and button battery 5.

[0036] In the battery fixing device of this embodiment, the clamping block is movable and can be used to clamp and fix batteries 5 of different sizes; at the same time, the spring coil 31 is elastic and adjustable, and the clamping member 2 can tightly fit and clamp batteries 5 of different sizes, and is suitable for clamping and fixing batteries 5 of different sizes. Specifically, it is suitable for clamping and fixing different types of batteries 5 such as cylindrical batteries 5 and button batteries 5.

[0037] Combined with reference Figure 4 and Figure 5 In some embodiments, the clamping member 2 includes an abutting portion 21 and a supporting portion 22, wherein the supporting portion 22 is connected to the abutting portion 21; and the adjusting pin 3 is connected to the abutting portion 21. The supporting portion 22 is used to fit against the battery 5, clamping and fixing the battery 5.

[0038] In some embodiments, the clamping member 2 includes an abutment portion 21, a support portion 22, and an extension portion 23. One end of the support portion 22 is connected to the abutment portion 21, and the other end is connected to the extension portion 23. The adjustment pin 3 is connected to the abutment portion 21. The extension portion 23 can be used to stretch and expand the support portion 22.

[0039] Specifically, the left and right ends of the clamping member 2 can be abutment portions 21, and the middle portion is a support portion 22 connecting the left and right abutment portions 21. The support portion 22 is also connected to the extension portion 23. In some embodiments, in order to better fix the battery 5, the number of adjustment pins 3 corresponds to the number of abutment portions 21, and the adjustment pins 3 are each provided with a spring ring 31. When the battery 5 needs to be fixed, the battery 5 is fitted with the support portion 22, and the extension portion 23 stretches the support portion 22. The abutment portions 21 at the left and right ends of the clamping member 2 squeeze the spring ring 31 on the adjustment pin 3, and then the spring ring 31 rebounds under the force, pushing the support portion 22 to fit the battery 5, thereby clamping and fixing the battery 5. The outer edge of the clamping member 2 can be curved to better fit the cylindrical battery 5 and the button battery 5.

[0040] Combined with reference Figure 6 In some embodiments, the clamping member 2 further includes a fitting portion 24, which is connected to the support portion 22, with the outer edge of the fitting portion 24 extending along the support portion 22; the cross-sectional width of the top end of the fitting portion 24 gradually decreases from bottom to top; and / or the cross-sectional width of the bottom end of the fitting portion 24 gradually decreases from top to bottom. The cross-sectional width of the top end of the fitting portion 24 gradually decreases from bottom to top to facilitate the insertion of the battery 5; the cross-sectional width of the bottom end of the fitting portion 24 gradually decreases from top to bottom to facilitate the clamping and fixing of the button battery 5 after insertion.

[0041] Combined with reference Figure 7 The button battery 5 is small in size, and direct clamping may cause deviation, which may lead to failure to fix or damage the button battery 5. Therefore, in some embodiments, a fitting groove 241 is provided on the side of the fitting portion 24 away from the support portion 22. Specifically, the fitting groove 241 can match the button battery 5 to be fixed, so as to better clamp and fix the button battery 5 and prevent the button battery 5 from deviating.

[0042] Among them, the fitting part 24 and the supporting part 22 can be connected magnetically. When it is necessary to fix batteries 5 of different sizes, the fitting part 24 and the supporting part 22 with the fitting groove 241 matching the battery 5 of the size can be replaced by magnetic attraction, thereby achieving the effect of clamping and fixing batteries 5 of different sizes. This process is simple and quick, and there is no need to replace the entire clamping part 2.

[0043] Combined with reference Figure 8 In some embodiments, the clamping member 2 is a pair of symmetrically arranged members, and the pair of clamping members 2 are respectively a first clamping member and a second clamping member, the first clamping member is arranged at the left end of the fixing base 1, and the second clamping member is arranged at the right end of the fixing base 1, and the first clamping member and the second clamping member are axially symmetrical.

[0044] Specifically, the first clamping member includes a first abutment portion, a first support portion, and a first extension portion. One end of the first support portion is connected to the first abutment portion, and the other end is connected to the first extension portion. The adjustment pin 3 is connected to the first abutment portion. Both the left and right ends of the first clamping member can serve as first abutment portions, while the middle portion serves as the first support portion connecting the left and right first abutment portions. The first support portion is also connected to the first extension portion.

[0045] The second clamping member has the same structure as the first and is symmetrically arranged. Specifically, the second clamping member includes a second abutment portion, a second support portion, and a second extension portion. One end of the second support portion is connected to the second abutment portion, and the other end is connected to the second extension portion. The adjustment pin 3 is connected to the second abutment portion. Both the left and right ends of the second clamping member can serve as second abutment portions, while the middle portion serves as a second support portion connecting the left and right second abutment portions. The second support portion is also connected to the second extension portion.

[0046] Meanwhile, the number of the adjustment pins 3 corresponds to the number of the abutment portions 21 (including the first abutment portion and the second abutment portion), which is at least two.

[0047] Before placing the battery 5 to be fixed, the supporting portion 22 (including the first supporting portion and the second supporting portion) is stretched open by the extending portion 23, and the spring coils 31 on the adjusting pin 3 connected to the abutting portion 21 (including the first abutting portion and the second abutting portion) are compressed. After the battery 5 is placed, the spring coils 31 rebound, pushing the abutting portion 21 (including the first abutting portion and the second abutting portion) to move, and at the same time driving the supporting portion 22 (including the first supporting portion and the second supporting portion) to move, thereby fixing the battery 5.

[0048] Specifically, the first clamping member may include a first bonding portion that can be magnetically connected to the first supporting portion; the second clamping member may include a second bonding portion that can be magnetically connected to the second supporting portion. Both the first bonding portion and the second bonding portion may be provided with a bonding groove 241 that matches the battery 5.

[0049] In some embodiments, a groove corresponding to the battery 5 is provided at the bottom end of the fixing base 1 for fixing and positioning the battery 5 .

[0050] Combined with reference Figure 9 and Figure 10 In some embodiments, the bottom end of the fixing base 1 is provided with a fitting bottom 13, which is engaged with the bottom end of the fixing base 1 and is provided with a snap-fitting groove 131. Specifically, the snap-fitting groove 131 matches the battery 5 to be fixed; the snap-fitting groove 131 is used to fix and position the battery 5 and prevent the battery 5 from shifting; and for smaller button batteries 5, the snap-fitting groove 131 can also cooperate with the fitting groove 241 on the fitting portion 24 to further fix the position of the button battery 5.

[0051] Among them, the fitting bottom 13 and the fixing base 1 can be connected by interlocking or magnetic connection. When it is necessary to fix batteries 5 of different sizes, the fitting bottom 13 with the engaging groove 131 matching the battery 5 of the size can be replaced and interlocked or magnetically attracted to the fixing base 1, thereby achieving the effect of fixing and positioning batteries 5 of different sizes. This process is simple and quick, and there is no need to replace the entire fixing base 1.

[0052] In order to improve the connection stability between the fixing seat 1 and the adjusting pin 3 , in some embodiments, a through hole 11 corresponding to the adjusting pin 3 is provided on the fixing seat 1 ; the adjusting pin 3 passes through the through hole 11 and abuts against the abutting portion 21 .

[0053] In some embodiments, the battery securing device further includes a baffle 4 disposed on the fixing base 1; the abutment portion 21 is located between the baffle 4 and the fixing base 1. The baffle 4 is used to prevent the abutment portion 21 from detaching from the fixing base 1. Multiple baffles 4 may be provided. Specifically, the fixing base 1 and baffle 4 are secured by bolts, and corresponding holes are provided on both the fixing base 1 and the baffle 4.

[0054] The sum of the maximum widths A of a pair of clamping members 2 can be greater than, equal to, or less than the inner cavity length B of the fixing base. In some embodiments, when the sum of the maximum widths A of a pair of clamping members 2 is greater than or equal to the inner cavity length B of the fixing base. That is, when the sum of the maximum widths A of the first clamping member and the maximum widths A of the second clamping member is greater than or equal to the inner cavity length B of the fixing base, the clamping member 2 cannot move within the fixing base 1. Therefore, the fixing base 1 is provided with a slot 12 corresponding to the protrusion 23. Specifically, the number of the slots 12 corresponds one-to-one to the number of the protrusion 23. If the clamping members 2 are a pair, the number of the slots 12 is also a corresponding pair. The provision of the slots 12 allows the protrusion 23 to extend from the slots 12 when the clamping member 2 is expanded without colliding with the fixing base 1. This increases the expandable range of the clamping member 2 and, blocked by the sidewalls of the fixing base 1, allows it to clamp larger batteries 5.

[0055] Combined with reference Figure 1 and Figure 3 In some embodiments, the clamping block includes a first fixing block 61, a second fixing block 62, a first adjustment block 63, and a second adjustment block 64. The first fixing block 61 is located at the upper end of the base plate 6, the second fixing block 62 is located at the left end of the base plate 6, the first adjustment block 63 is located at the lower end of the base plate 6, and the second adjustment block 64 is located at the right end of the base plate 6. The first adjustment block 63 is engaged with the base plate 6, and the second adjustment block 64 is engaged with the base plate 6. The fixing base 1 is provided on the base plate 6 and can be located at the center of the base plate 6, so as to facilitate fixing the battery 5 at the center of the base plate 6, thereby enabling subsequent testing of the battery 5.

[0056] That is, the positions of the first adjusting block 63 and the second adjusting block 64 can be adjusted by adjusting the engagement positions between the first adjusting block 63 and the second adjusting block 64 and the base plate 6, so that the larger-sized battery 5 placed on the base plate 6 is respectively in contact with and fixedly fitted to the first fixing block 61, the second fixing block 62, the first adjusting block 63 and the second adjusting block 64.

[0057] Combined with reference Figure 2 and Figure 3 In some embodiments, the first adjustment block 63 is provided with a first protrusion, and the base plate 6 is provided with a first fixing groove 631 corresponding to the first protrusion; the second adjustment block 64 is provided with a second protrusion, and the base plate 6 is provided with a second fixing groove 641 corresponding to the second protrusion. The first protrusion of the first adjustment block 63 slides and engages with the first fixing groove 631, and the second protrusion of the second adjustment block 64 slides and engages with the second fixing groove 641.

[0058] When the battery 5 is placed on the bottom plate 6 and fits with the first fixing block 61 and the second fixing block 62 respectively, the first protrusion is slidably engaged in the first fixing groove 631 to fix the position of the first adjusting block 63, thereby fitting the upper and lower ends of the battery 5 to the first fixing block 61 and the first adjusting block 63 respectively; then the second protrusion is slidably engaged in the second fixing groove 641 to fix the position of the second adjusting block 64, thereby fitting the left and right ends of the battery 5 to the second fixing block 62 and the second adjusting block 64 respectively, thereby clamping and fixing the battery 5.

[0059] That is, the battery fixing device can clamp and fix the battery 5 through the clamping member 2 connected to the fixing seat 1, and is suitable for clamping and fixing smaller-sized batteries 5, such as cylindrical batteries 5 and button batteries 5; it can also clamp and fix the battery 5 through the first fixing block 61, the second fixing block 62, the first adjustment block 63 and the second adjustment block 64 on the bottom plate 6, and is suitable for clamping and fixing larger-sized batteries 5, such as laminated batteries 5, wound batteries 5, and 3C batteries 5.

[0060] The first fixing block 61 and the base plate 6 may also be connected by a snap-fit ​​connection, allowing the first fixing block 61 to be adjusted externally on the base plate 6. The second fixing block 62 and the base plate 6 may also be connected by a snap-fit ​​connection, allowing the second fixing block 62 to be adjusted externally on the base plate 6. Specifically, in some embodiments, the first fixing block 61 may be provided with a third protrusion, and the base plate 6 may be provided with a third fixing groove 611 corresponding to the third protrusion; and / or the second fixing block 62 may be provided with a fourth protrusion, and the base plate 6 may be provided with a fourth fixing groove 621 corresponding to the fourth protrusion.

[0061] Among them, the bottom plate 6, the first fixing block 61, the second fixing block 62, the first adjusting block 63 and the second adjusting block 64 can directly contact the battery 5, and their material can be selected from polyurethane material, which can protect the battery 5 from damage.

[0062] Combined with reference Figure 1 In some embodiments, the battery fixture further includes a connecting block 7, which is located between the base plate 6 and the fixing base 1 and connects the base plate 6 and the fixing base 1. Specifically, the connecting block 7 is provided with slots corresponding to the fixing base 1, ensuring a tight connection between the connecting block 7 and the fixing base 1. The connecting block 7 is also provided with a plurality of holes for fixed connection with the base plate 6, which can be specifically bolted.

[0063] The battery fixing device may also include a controller and a sensor. Specifically, the first and second clamping members, as well as the first fixing block 61, the second fixing block 62, the first adjustment block 63, and the second adjustment block 64 on the base plate 6, are all connected to the controller. Furthermore, the first and second clamping members, as well as the first fixing block 61, the second fixing block 62, the first adjustment block 63, and the second adjustment block 64 on the base plate 6, are all provided with a sensor. The sensor is used to sense the position of the component and the status of the battery 5, while the controller is used to control and adjust the position of the first and second clamping members, the first fixing block 61, the second fixing block 62, the first adjustment block 63, and the second adjustment block 64, thereby improving the automation level of the battery fixing device and enabling the device to automatically clamp and release the battery 5.

[0064] Combined with reference Figure 1 and Figure 2 In a second embodiment of the present application, a battery fixing device is provided for fixing a battery 5, comprising a first clamping assembly and a second clamping assembly, wherein the second clamping assembly comprises a base plate 6 and a clamping block, the clamping block being disposed on the base plate 6 and being used to clamp a wound battery 5, a laminated battery 5, or a 3C battery 5. The first clamping assembly comprises a fixing base 1, an adjusting pin 3, and a clamping member 2; the fixing base 1 is disposed on the base plate 6, and the clamping member 2 is disposed on the fixing base 1; one end of the adjusting pin 3 is connected to the clamping member 2, and the other end is connected to the fixing base 1; a spring coil 31 is sleeved on the adjusting pin 3. The fixing base 1 is located at the center of the base plate 6.

[0065] The clamping members 2 are a pair of symmetrically arranged members. Specifically, the pair of clamping members 2 is a first clamping member and a second clamping member. The first clamping member includes a first abutting portion, a first supporting portion, and a first extending portion, and the second clamping member includes a second abutting portion, a second supporting portion, and a second extending portion. The first clamping member is arranged at the left end of the fixing seat 1, and the second clamping member is arranged at the right end of the fixing seat 1. The first clamping member and the second clamping member are axially symmetrical, which facilitates the preparation of the device assembly and reduces the preparation cost. At the same time, the battery 5 can also be clamped and fixed to the center position of the supporting portion 22 of the first clamping member and the second clamping member, that is, fixed to the center position of the fixing seat 1, which facilitates the positioning of the battery 5 and subsequent testing of the battery 5.

[0066] The left and right ends of the first clamping member are both first abutting parts, and the middle part is connected to the first abutting parts at both ends through the first supporting part; the left and right ends of the second clamping member are both second abutting parts, and the middle part is connected to the second abutting parts at both ends through the second supporting part; at this time, the number of adjusting pins 3 corresponds to the number of abutting parts 21 (including the first abutting part and the second abutting part), which is 4.

[0067] The clamping member 2 also includes a fitting portion 24 connected to the support portion 22. The outer edge of the fitting portion 24 extends along the support portion 22. The cross-sectional width of the top of the fitting portion 24 gradually decreases from bottom to top. This gradually decreases the cross-sectional width of the top of the fitting portion 24 from bottom to top, facilitating the insertion of the battery 5.

[0068] A fitting groove 241 is provided on one side of the fitting portion 24 away from the supporting portion 22. Specifically, the fitting groove 241 can match the button battery 5 to be fixed, so as to better clamp and fix the button battery 5 and prevent the button battery 5 from shifting.

Specifically, the snap-fitting groove 131 matches the battery 5 to be fixed; the snap-fitting groove 131 is used to fix and position the battery 5 and prevent the battery 5 from shifting. At the same time, for smaller button batteries 5, the snap-fitting groove 241 on the fitting portion 24 can also cooperate with the snap-fitting groove 241 on the fitting portion 24 to further fix the position of the button battery 5.

[0070] A baffle 4 is provided on the fixing base 1; the abutment portion is located between baffle 4 and the fixing base 1. Baffle 4 is used to prevent the abutment portion 21 from detaching from the fixing base 1. Specifically, two baffles 4 can be provided on the fixing base 1, one above the first abutment portion and the other above the second abutment portion.
