[0025] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please refer to Figures 1 to 3 This utility model embodiment provides a latch 10, including a fixing plate 11, an elastic plate 12, a locking plate 13, and a pressing plate 14. For ease of explanation, a coordinate system XYZ is established, which represents the first direction X, the second direction Z, and the third direction Y, respectively. The first direction X, the second direction Z, and the third direction Y intersect each other, and can further be perpendicular to each other. The overall length direction of the latch 10 can be approximately the first direction X, the width direction approximately the third direction Y, and the thickness direction approximately the second direction Z.

[0028] The fixing plate 11 is plate-shaped and can be a flat plate, a curved plate, etc. The orthographic projection shape of the fixing plate 11 in the second direction Z can be rectangular, trapezoidal, circular, etc., without limitation. Optionally, the fixing plate 11 is a flat plate, with its length direction in the third direction Y, its width direction in the first direction X, and its thickness direction in the second direction Z. The orthographic projection shape of the fixing plate 11 in the second direction Z is rectangular. The fixing plate 11 is used for connection and fixation with the supporting member and serves as the supporting connection base for other parts of the latch 10. For example, refer to... Figure 4 and Figure 5 The supporting component may be, for example, the housing 20 of the battery device 100, or other components, without limitation.

[0029] The elastic plate 12 is plate-shaped and can be a flat plate, a curved plate, etc. In its orthographic projection in the second direction Z, the shape of the elastic plate 12 can be rectangular, trapezoidal, etc., without limitation. Optionally, the elastic plate 12 is a curved plate, with its length direction approximately in the first direction X, its width direction approximately in the third direction Y, and its thickness direction approximately in the second direction Z. The orthographic projection shape of the elastic plate 12 in the second direction Z is rectangular, and the length > width > thickness of the elastic plate 12.

[0030] One end of the elastic plate 12 in the first direction X is connected to the fixed plate 11. The elastic plate 12 can be connected and fixed to the fixed plate 11 by welding, integral molding, or other methods. When integrally molded, it can be achieved by cutting or bending from a large plate. One end of the elastic plate 12 is connected to the fixed plate 11 to form a cantilever structure, which allows the elastic plate 12 to elastically deform in the second direction Z, allowing the elastic plate 12 to rotate around the fixed plate 11, and the end of the elastic plate 12 away from the fixed plate 11 can move in the second direction Z.

[0031] Optionally, one end face of the elastic plate 12 in the first direction X is connected to one end face of the fixed plate 11 in the first direction X, thereby reducing the overall space occupied by the fixed plate 11 and the elastic plate 12 in the second direction Z. Further, the length of the fixed plate 11 is greater than the width of the elastic plate 12, and the elastic plate 12 is connected to the middle region of the fixed plate 11 in the first direction X, with the midpoint of the elastic plate 12 in the first direction X coinciding with the midpoint of the fixed plate 11 in the first direction X. Alternatively, one end of the elastic plate 12 in the first direction X can also be stacked and connected to the fixed plate 11 in the second direction Z.

[0032] Optionally, the elastic plate 12 and the fixed plate 11 are flush and coplanar in the second direction Z. That is, the portion of the elastic plate 12 adjacent to the fixed plate 11 is flush with both sides of the elastic plate 12 in the second direction Z, and the angle between the portion of the elastic plate 12 adjacent to the fixed plate 11 and the fixed plate 11 is 180°. When the elastic plate 12 is flattened into a plate, the elastic plate 12 and the fixed plate 11 can be integrally formed into a single plate. In this way, when the surface of the fixed plate 11 in the second direction Z is in close contact with the surface of the supporting member, the portion of the elastic plate 12 adjacent to the fixed plate 11 is also approximately in close contact with the surface of the supporting member. This reduces the space occupied in the Z direction, resulting in a smaller space occupied by the latch 10, which is beneficial for the compact arrangement of components such as the battery device 100.

[0033] The locking plate 13 is plate-shaped and can be a flat plate, a curved plate, etc. In the orthographic projection of the third direction Y, the shape of the elastic plate 12 can be rectangular, trapezoidal, parallelogram, etc., without limitation. Optionally, the locking plate 13 is a curved plate, with the length direction of the locking plate 13 approximately in the first direction X, the width direction approximately in the second direction Z, and the thickness direction approximately in the third direction Y.

[0034] The locking plate 13 is connected to the elastic plate 12 and protrudes from one side of the elastic plate 12 in the second direction Z. The locking plate 13 can be connected and fixed to the elastic plate 12 by welding, integral molding, or other methods. In integral molding, it can be achieved by cutting or bending from a large plate. The locking plate 13 can be connected to the surface of the elastic plate 12 in the second direction Z, or to the side of the elastic plate 12 in the third direction Y, without limitation. When the elastic plate 12 rotates around the fixed plate 11, the locking plate 13 also rotates, allowing the locking plate 13 to move in the second direction Z. The locking plate 13 is used for locking, and the movement of the elastic plate 12 achieves unlocking.

[0035] The pressing plate 14 is plate-shaped and can be a flat plate, a curved plate, etc. In the orthographic projection of the second direction Z, the shape of the elastic plate 12 can be rectangular, trapezoidal, etc., without limitation. Optionally, the pressing plate 14 is a curved plate, with the length direction of the pressing plate 14 approximately in the first direction X, the width direction approximately in the third direction Y, and the thickness direction approximately in the second direction Z.

[0036] The pressing plate 14 is connected to the other end of the elastic plate 12 in the first direction X, and the pressing plate 14 extends away from the fixed plate 11. The pressing plate 14 can be connected and fixed to the elastic plate 12 by welding, integral molding, or other methods. When integrally molded, it can be achieved by cutting or bending from a large plate. The pressing plate 14 can be connected to the surface of the elastic plate 12 in the second direction Z, or to the side of the elastic plate 12 in the third direction Y, without limitation. Optionally, in the orthographic projection of the second direction Z, both the elastic plate 12 and the pressing plate 14 are rectangular, and the width of the pressing plate 14 is equal to the width of the elastic plate 12. Optionally, one end face of the pressing plate 14 in the first direction X is connected to one end face of the elastic plate 12 in the first direction X. Alternatively, the pressing plate 14 can also be stacked with the elastic plate 12 in the second direction Z.

[0037] Because the elastic plate 12 is a cantilever structure, the pressing plate 14 is subjected to pressure in the second direction Z (e.g., Figure 6 , Figure 7 When pressed (as shown in Figure F), the pressing plate 14 can drive the elastic plate 12 to rotate and elastically deform around the fixed plate 11, thereby driving the locking plate 13 to move accordingly, realizing the switch from the locked state to the unlocked state; after the pressure of the pressing plate 14 is removed, the elastic plate 12 can return to the position when it is in the locked state under the action of elastic tension. That is, the function of the pressing plate 14 is only to unlock, and after unlocking, the elastic plate 12 can automatically return to the position when it is in the locked state under the action of elastic tension. It can be understood that the user can apply pressure along the second direction Z to the pressing plate 14 by hand or with a simple tool.

[0038] Optionally, the elastic plate 12 can rotate around the fixed plate 11 within an angle range of 15°-30°. Specifically, this angle range can be 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, etc., without limitation. Within this angle range, the locking plate 13 can be moved to achieve locking and unlocking functions without requiring excessive space due to excessive rotation angle. If the angle range is less than 15°, it will be difficult to move the locking plate 13 a sufficient distance, making it difficult to unlock in the locked state or return to the locked state in the unlocked state. If the angle range is greater than 30°, a large space is required for the elastic plate 12 to rotate, resulting in a larger product structure with the latch 10 installed, or the elastic plate 12 may interfere with adjacent components and be difficult to rotate.

[0039] In practical application, the fixing plate 11 is fixed to the supporting member. The supporting member has a hole. When no force is applied to the pressing plate 14, the locking plate 13 extends out from the hole in the supporting member. A component adjacent to the supporting member has another hole, and the locking plate 13 also extends into the hole of this component, thus locking the supporting member and the adjacent component. When pressure is applied to the pressing plate 14, the elastic plate 12 can drive the locking plate 13 out of the hole in the component, allowing the supporting member to separate from the adjacent component and unlock. After unlocking, the supporting member and the adjacent component can be moved relative to each other to achieve disassembly. After the pressure of the pressing plate 14 is removed, the elastic plate 12 extends out from the hole in the supporting member under elastic tension, automatically locking itself.

[0040] The latch 10 of this utility model embodiment forms a cantilever structure by setting an elastic plate 12. The elastic tension of the elastic plate 12 can achieve automatic locking. By setting a pressing plate 14, it can be unlocked by simply applying pressure to the pressing plate 14. The structure is simple, no professional tools are required, the operation is convenient, the unlocking time can be shortened, and the disassembly efficiency can be improved.

[0041] Optionally, the fixing plate 11, elastic plate 12, locking plate 13, and pressing plate 14 are integral components formed by bending flat plates. Integral components have good structural strength and can improve reliability. In specific processing, the corresponding shapes can be cut from a large flat plate first, and then the plate can be bent to obtain the shape of the latch 10. Optionally, the fixing plate 11 does not need to be bent; the elastic plate 12, locking plate 13, and pressing plate 14 need to be bent, resulting in a structure where the fixing plate 11 is a flat plate, and the elastic plate 12, locking plate 13, and pressing plate 14 are all bent plates. By using a flat plate for bending, the thickness of the fixing plate 11, elastic plate 12, locking plate 13, and pressing plate 14 can be approximately equal. For example, a steel plate can be used for bending; the material of the steel plate can be stainless steel (e.g., SUS304), spring steel (e.g., 65Mn), etc., and the thickness of the steel plate can be 0.8mm-2mm. Optionally, when using the battery device 100 described later, a steel plate thickness of 1mm can be selected, which provides sufficient strength while avoiding excessive weight gain due to excessive thickness. Steel plates have high structural strength and good rigidity, can undergo elastic deformation, and are relatively inexpensive, making them an excellent material choice.

[0042] Understandably, in specific processes, the sharp corners of the fixing plate 11, elastic plate 12, locking plate 13 and pressing plate 14 can be rounded, the connected areas can be smoothly transitioned, and heat treatment, grinding and polishing can also be performed to make the latch 10 have better performance.

[0043] In one embodiment, reference Figure 1 and Figure 2The fixing plate 11 is a flat plate and includes a first plane 111 and a second plane 112 opposite to each other in the second direction Z. The elastic plate 12 is a curved plate and includes a first surface 121 and a second surface 122 opposite to each other in the second direction Z. The first surface 121 is smoothly connected to the first plane 111, and the second surface 122 is smoothly connected to the second plane 112. The locking plate 13 protrudes from the first surface 121. In the state where the elastic plate 12 is not elastically deformed, the first surface 121 is concave and the second surface 122 is convex.

[0044] The end of the elastic plate 12 away from the fixed plate 11 protrudes from the first plane 111. Figure 2 The dashed line shows the plane after the extension of the first plane 111. It can be seen that one end of the elastic plate 12 in the first direction X is flush with the fixed plate 11, while the other end curves upward and protrudes from the first plane 111. In other words, the end of the elastic plate 12 furthest from the fixed plate 11 is located on the first plane 111 (see reference). Figure 2 (The dashed line in the middle) is on the side facing away from the second plane 112.

[0045] Optional, see reference Figure 2 The first surface 121 and the second surface 122 are both curved in the orthographic projection of the third direction Y. That is, the elastic plate 12 is roughly an arc plate with the central axis extending along the second direction Z.

[0046] refer to Figures 4 to 7 When the latch 10 is applied, the fixing plate 11 is tightly installed and fixed to a plane of the support member (e.g., the housing 20 of the battery device 100), with the first surface 121 facing the plane of the support member that is fixed to the fixing plate 11. The locking plate 13 extends out from the hole in the support member. Since the first surface 121 is concave and the second surface 122 is convex, the end of the elastic plate 12 away from the fixing plate 11 protrudes from the first plane 111, allowing the end of the elastic plate 12 away from the fixing plate 11 to elastically abut against the support member, and the elastic plate 12 will undergo a certain elastic deformation. That is to say, after the latch 10 is installed, the elastic plate 12 has rotated around the fixing plate 11 by an angle, which can be 5°-12°, specifically 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, etc. In other words, when the elastic plate 12 is not elastically deformed, the angle between the line connecting the end of the elastic plate 12 away from the fixed plate 11 and the end of the elastic plate 12 connected to the fixed plate 11 and the first plane 111 is 5°-12°. This allows the elastic plate 12 to generate elastic tension, and the end of the elastic plate 12 away from the fixed plate 11 to exert pressure (e.g., 5N-10N) on the support member. The locking plate 13 remains protruding from the hole in the support member, thus achieving the function of maintaining the locked state.

[0047] When the latch 10 is in the locked state, the elastic plate 12 has rotated a small angle around the fixed plate 11, producing a certain elastic deformation to maintain the locked state. When unlocking is required, pressure in the second direction Z is applied to the pressing plate 14, causing the elastic plate 12 to rotate around the fixed plate 11 by a certain angle, which can be 10°-18°, specifically 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, etc. This allows the end of the elastic plate 12 away from the fixed plate 11 to separate from the support member and gradually move away from the support member, and the locking plate 13 retracts from the hole in the support member, thus achieving unlocking. After releasing the pressure on the pressing plate 14, the elastic plate 12 can automatically rebound under its own elastic tension to the state where the end of the elastic plate 12 away from the fixed plate 11 elastically abuts against the support member, and the locking plate 13 re-extends from the hole in the support member, thus automatically achieving the locking function. The aforementioned range of the angle in which the elastic plate 12 rotates around the fixed plate 11 is the sum of the angle in which the elastic plate 12 rotates around the fixed plate 11 when it is in the locked state and the angle in which the elastic plate 12 continues to rotate around the fixed plate 11 due to the pressure applied to the pressing plate 14 for unlocking.

[0048] Therefore, by setting the fixing plate 11 of this embodiment to be a flat plate and the elastic plate 12 to be a curved plate with one end raised, the latch 10 can be ensured to be in the locked state in the initial state and can automatically return to the locked state after unlocking, without the need for manual locking, making the operation more convenient and the functions more abundant.

[0049] Optional, see reference Figure 2 When the elastic plate 12 is not elastically deformed, there is an included angle A between the first surface 121 of the elastic plate 12 near the fixed plate 11 and the first surface 121 near the pressing plate 14, which satisfies: 160°≤A<180°.

[0050] In this design, the end of the elastic plate 12 adjacent to the fixed plate 11 is flush with and coplanar with the fixed plate 11. Therefore, the first surface 121 of the end of the elastic plate 12 adjacent to the fixed plate 11 can be considered as the first plane 111. The end of the elastic plate 12 adjacent to the pressing plate 14 is bent and raised, with an included angle A satisfying 160°≤A<180°. The elastic plate 12 has a stable structure and exhibits a certain degree of elastic deformation in the locked state, thus maintaining the locked state. When unlocking, the pressing plate 14 does not require a large force to make the elastic plate 12 rotate around the fixed plate 11, thereby unlocking the latch 10. If the included angle A<160°, excessive bending of the elastic plate 12 will cause plastic deformation at the junction of the elastic plate 12 and the fixed plate 11 after the latch 10 is installed on the support member, leading to structural failure. This also avoids the pressing plate 14 requiring a large force to move the elastic plate 12. If the included angle A = 180°, the elastic plate 12 is flat and flush with the fixed plate 11 without bending. When the fixed plate 11 is tightly fixed to the support member, the end of the elastic plate 12 away from the fixed plate 11 may not elastically abut against the support member. The elastic plate 12 will not produce elastic deformation and cannot provide the ability to maintain the locked state, which may lead to instability of the locked state. If the included angle A > 180°, similar to the included angle A = 180°, the end of the elastic plate 12 away from the fixed plate 11 will not elastically abut against the support member, which may lead to instability of the locked state or even failure to achieve the locking function.

[0051] The included angle A can be 160°, 165°, 170°, 175°, 178°, etc. Optionally, 170°≤A<180°, which allows the end of the elastic plate 12 away from the fixed plate 11 to protrude less from the first surface 121 (i.e., the degree of upward tilt). In the locked state, while ensuring a certain amount of deformation elastically resisting the support member, the deformation of the elastic plate 12 is small, reducing space occupation, and at the same time, it can achieve unlocking with less pressure on the pressing plate 14.

[0052] Optional, see reference Figures 1 to 3 The elastic plate 12 includes a first side 123 and a second side 124 opposite to each other in the Y direction. There are multiple locking plates 13, and at least one locking plate 13 is connected to each of the first side 123 and the second side 124.

[0053] During the fabrication of the latch 10, the locking plate 13 is initially on the same plane as the elastic plate 12. Then, the locking plate 13 is bent so that it extends from the first side 123 and the second side 124, bends, and protrudes towards the first surface 121. Specifically, during bending, pressure from the second surface 122 towards the first surface 121 is applied to the end of the locking plate 13 in the third direction Y, away from the elastic plate 12, causing the end of the locking plate 13 away from the elastic plate 12 to tilt towards the first surface 121. The portion of the locking plate 13 adjacent to the elastic plate 12 is smoothly curved, avoiding stress concentration at the joint, thus improving structural strength and locking effect. The number of locking plates 13 can be 2, 3, 4… The number of locking plates 13 connected to the first side 123 and the second side 124 is not limited. For example… Figures 1 to 3 An embodiment is shown with two locking plates 13, and one locking plate 13 is connected to each of the first side 123 and the second side 124.

[0054] Optionally, in the orthographic projection onto the Y-axis, the locking plate 13 of the first side 123 and the locking plate 13 of the second side 124 completely overlap. In other words, the locking plate 13 of the first side 123 and the locking plate 13 of the second side 124 are symmetrical with respect to the elastic plate 12. This facilitates design and manufacturing; for example, when designing how to cut a large plate, the pattern of one locking plate 13 can simply be symmetrically arranged to the other side. During manufacturing, the locking plates 13 on both sides can be bent in the same way with the same force. A symmetrical plurality of locking plates 13 also provides better locking performance. In this embodiment, the number of locking plates 13 is an even number, for example, such as... Figures 1 to 3 There are two locking plates 13 shown.

[0055] Optionally, the height of the locking plate 13 protruding from the first surface 121 can be 2mm-5mm, specifically 2mm, 3mm, 4mm, 5mm, etc., without limitation. This height satisfies the locking requirement without being too high, which would require the elastic plate 12 to rotate a large angle to move the locking plate 13 and unlock. If the height is less than 2mm, it is too small to achieve the locking function; if the height is greater than 5mm, it is too large to unlock.

[0056] Optional, see reference Figure 1 and Figure 2 The locking plate 13 includes a guide surface 131 and a limiting surface 132. The guide surface 131 is located at the end of the locking plate 13 facing the fixing plate 11, and the limiting surface 132 is located at the end of the locking plate 13 facing the pressing plate 14. The guide surface 131 has an angle B with the first surface 121, and the limiting surface 132 has an angle C with the first surface 121, satisfying: 120°≤B≤150°, 85°≤C≤95°.

[0057] Taking the process of the latch 10 being installed on the support member, and the support member moving to lock and unlock with the adjacent component as an example, the locking plate 13 of the latch 10 extends out of the hole in the support member. The movement of the support member causes the latch 10 to move relative to the component. The guide surface 131 of the locking plate 13 first touches the component and is pressed, and the locking plate 13 retracts into the hole in the support member. When the hole in the support member is aligned with the hole in the component, the pressure of the component on the locking plate 13 disappears, and the locking plate 13 springs back and extends out of the hole in the support member again and into the hole in the component, thus achieving locking. When the support member moves in the opposite direction, the limiting surface 132 abuts against the side wall of the hole in the component, preventing the support member from returning along the original path. Pressure must be applied to the pressing plate 14 to make the locking plate 13 re-exit from the hole in the component in order to unlock.

[0058] In this embodiment, angles B and C can be obtained by taking any position on the first surface 121 and making an angle with the guide surface 131 and the limiting surface 132. In this embodiment, angles B and C can be the angles before the latch 10 is installed onto the support member, the angles after the latch 10 is installed onto the support member, or the angles after the latch 10 has locked the support member and a nearby component; there are no restrictions. Specifically, angle B can be 120°, 125°, 130°, 135°, 140°, 145°, 150°, etc., without limitation. Specifically, angle C can be 85°, 88°, 90°, 92°, 95°, etc., without limitation.

[0059] The included angle of the guide surface 131 is set to form an inclined slope. During assembly, the support component only needs to be pushed to translate relative to the component. After the guide surface 131 contacts the component, it can slide relative to the component. It can automatically lock without the need to operate the latch 10. The relatively steep limiting surface 132 can play a limiting role and ensure that it is in the locked state.

[0060] The locking plate 13 may also include a connecting surface 133, which is the end face of the locking plate 13 away from the elastic plate 12, that is, the top surface of the locking plate 13 protruding from the first surface 121. The connecting surface 133 connects the guide surface 131 and the limiting surface 132, and the joint can be smoothly transitioned. The connecting surface 133 can be approximately parallel to the first surface 121, so that when the locking plate 13 extends and retracts from the hole of the self-supporting member, all parts of the connecting surface 133 extend or retract approximately uniformly, so that the locking plate 13 can achieve locking and unlocking with a small movement distance, and the rotation angle of the elastic plate 12 around the fixed plate 11 can be small, thereby reducing the need for large elastic deformation of the elastic plate 12, improving the reliability of the elastic plate 12, and avoiding structural failure.

[0061] Since the guide surface 131 is used to contact and slide relative to the components next to the support member, the end of the guide surface 131 away from the connecting surface 133 can protrude from the first surface 121. It is only necessary to ensure that the part of the locking plate 13 extending from the support member has the guide surface 131.

[0062] Optionally, the locking plate 13 may further include a clearance surface 134, which connects the end of the guide surface 131 away from the connecting surface 133 and the elastic plate 12. The clearance surface 134 may be perpendicular to the first side surface 123 (or the second side surface 124), which can prevent the locking plate 13 from occupying too much space in the first direction X and can reduce the size of the holes of the support member and the adjacent parts in the first direction X. Optionally, the clearance surface 134 may be parallel to the limiting surface 132 and both may be approximately perpendicular to the first direction X. The distance between the two is the length of the locking plate 13 (i.e., the size along the first direction X). Optionally, the distance between the clearance surface 134 and the limiting surface 132 may be 10mm-20mm, specifically 10mm, 12mm, 14mm, 15mm, 16mm, 18mm, 20mm, etc., without limitation. Setting such a distance can make the locking plate 13 have strong strength in the first direction X without occupying too much space, not easily damaged, and able to maintain the stability of the locked state. If the distance is less than 10mm, the strength is insufficient and it may be damaged when subjected to a large force in the locked state. If the distance is greater than 20mm, the size is too large, and the holes of the corresponding support components and parts need to be enlarged, which occupies a lot of space and is not conducive to the miniaturization of the structure.

[0063] In one embodiment, reference Figure 1 and Figure 3 The fixing plate 11 is provided with multiple mounting parts 113, which are spaced apart in the first direction X and the third direction Y.

[0064] The number of mounting parts 113 can be 2, 3, 4, etc., without limitation. Multiple mounting parts 113 can securely install the fixing plate 11 and maintain structural stability during the elastic deformation of the elastic plate 12. The mounting parts 113 can be holes, slots, protrusions, etc., without limitation. Correspondingly, the mounting parts 113 are used to cooperate with the supporting members to connect and fix the fixing plate 11 to the supporting members.

[0065] For example, such as Figure 1 and Figure 3 As shown, the mounting part 113 is a hole for fixing to the support member by riveting. There are two mounting parts 113, which are arranged at intervals along the diagonal of the rectangle of the fixing plate 11. By utilizing the four perimeters of the rectangle of the fixing plate 11 and the two mounting parts 113, a stable connection with the support member can be ensured.

[0066] In one embodiment, reference Figure 1 and Figure 2 The pressing plate 14 is located on the side of the first surface 121 facing the second surface 122.

[0067] Figure 2 The dashed line shows the extension of the first surface 121. It can be seen that the entire pressing plate 14 is located on the side of the first surface 121 facing the second surface 122. When the latch 10 is installed on the support member, the first surface 121 at the end of the elastic plate 12 away from the fixed plate 11 elastically abuts against the support member, and the pressing plate 14 is exposed outside the support member. The pressing plate 14 is located on the side of the first surface 121 facing the second surface 122, so that the pressing plate 14 is lower than the support member, which facilitates operation and avoids structural interference during installation.

[0068] Optionally, the pressing plate 14 includes an extension plate 141 and an operating plate 142. The extension plate 141 is connected to the elastic plate 12 and protrudes from the second surface 122. The operating plate 142 is connected to the end of the extension plate 141 away from the elastic plate 12. In the first direction X, the operating plate 142 extends from the extension plate 141 in a direction away from the elastic plate 12. In the second direction Z, the operating plate 142 extends from the extension plate 141 in a direction close to the first surface 121.

[0069] When pressure is applied to the pressing plate 14, the point of application is on the operating plate 142. With the extension plate 141 and the operating plate 142 provided, the pressing plate 14 is formed into a "√" shape. The end of the operating plate 142 away from the extension plate 141 is upturned, which allows for better force application when pressing the operating plate 142. During the rotation of the elastic plate 12 around the fixed plate 11, it is easy to maintain pressure on the operating plate 142 and avoid slippage, which is ergonomic.

[0070] In one embodiment, reference Figure 1 and Figure 5 The latch 10 also includes a pressing sleeve 15, which is fitted onto the pressing plate 14.

[0071] The press sleeve 15 can be made of insulating material, such as ABS plastic, or other types of material. The outer surface of the press sleeve 15 can be provided with anti-slip protrusions or grooves. The press sleeve 15 can be fitted onto the control panel 142. When pressure is applied to the control panel 142, the press sleeve 15 provides cushioning and anti-slip properties, preventing damage to the control panel 142. It also provides a better tactile feel when pressed by the user's fingers, preventing skin scratches. The insulating material prevents the latch 10 from becoming electrified and causing injury.

[0072] refer to Figures 4 to 7 and combined Figures 1 to 3This utility model embodiment also provides a battery device 100, including a housing 20 and a latch 10 as described in any of the foregoing embodiments. The housing 20 serves as the aforementioned support member. This battery device 100 can be used in various electrical devices 1000, such as energy storage batteries, power batteries, etc. For example, this battery device 100 can be used in data center energy storage batteries.

[0073] The housing 20 encloses a receiving cavity 21, and the housing 20 also has a mounting hole 22 communicating with the receiving cavity 21. The fixing plate 11 is received in the receiving cavity 21 and connected and fixed to the housing 20, and the pressing plate 14 is located outside the housing 20.

[0074] The receiving cavity 21 can also accommodate other structures such as batteries, without limitation. For example, the housing 20 is generally cuboid, including end plates 24 at both ends in the first direction X and four side plates 23 connected to the end plates 24, one of which has a mounting hole 22. A fixing plate 11 is connected and fixed to the side plate 23 with the mounting hole 22. For example, corresponding riveting holes 25 are provided on the side plate 23, and the mounting portion 113 on the fixing plate 11 is a hole. Rivets 26 are used to engage with the riveting hole 25 and the mounting portion 113 respectively to achieve riveting fixation. The first plane 111 of the fixing plate 11 remains in close contact with the inner wall surface of the side plate 23. An avoidance hole 27 is provided on the end plate 24, and the pressing plate 14 is located on the outside of the end plate 24. The avoidance hole 27 provides space for the elastic plate 12 to rotate around the fixing plate 11.

[0075] like Figure 4 and Figure 5 As shown, when the pressing plate 14 is not pressed, the locking plate 13 extends from the mounting hole 22 to the outside of the housing 20. At this time, the end of the elastic plate 12 away from the fixing plate 11 elastically abuts against the inner wall surface of the side plate 23, keeping the locking plate 13 extended from the mounting hole 22. In this state, it can be locked with the adjacent components.

[0076] like Figure 6 and Figure 7 As shown, when the pressing plate 14 is pressed, the locking plate 13 retracts into the cavity 21 and the mounting hole 22. The pressing plate 14 can drive the elastic plate 12 to rotate around the fixed plate 11. The end of the elastic plate 12 away from the fixed plate 11 separates from the side plate 23 and gradually moves away, causing the locking plate 13 to retract into the cavity 21 and the mounting hole 22. The retracted state can be unlocked.

[0077] The battery device 100 of this utility model embodiment is provided with a housing 20 and a latch 10. The latch 10 forms a cantilever structure by providing an elastic plate 12. The elastic tension of the elastic plate 12 can achieve automatic locking. By providing a pressing plate 14, it can be unlocked by simply applying pressure to the pressing plate 14. The structure is simple, no professional tools are required, the operation is convenient, the unlocking time can be shortened, and the disassembly efficiency can be improved.

[0078] refer to Figure 8 and Figure 9 and combined Figures 1 to 7 This utility model embodiment also provides an electrical device 1000, including a housing 200 and a battery device 100 as described in this utility model embodiment. The housing 200 is a component next to the aforementioned supporting member. The electrical device 1000 can be an industrial electrical device 1000, a commercial electrical device 1000, or a household or personal electrical device 1000, such as a power grid or data center, and is not limited thereto.

[0079] The housing 200 encloses the battery cavity 210, and the housing 200 also has a lock hole 220 that communicates with the battery cavity 210. The battery device 100 is used to house the battery cavity 210.

[0080] The housing 200 may have an opening at one end in the first direction X, and the shape of the battery cavity 210 matches the shape of the housing 20 of the aforementioned battery device 100. For example, the battery device 100 extends into the battery cavity 210 from the opening of the housing 200. When the battery device 100 is fully housed in the battery cavity 210, the four side plates 23 of the housing 20 of the battery device 100 are either in close contact with or have a small gap from the four side walls of the battery cavity 210. The position of the locking hole 220 in the housing 200 corresponds to the mounting hole 22 in the housing 20 of the battery device 100. When the battery device 100 is fully housed in the battery cavity 210, the mounting hole 22 and the locking hole 220 are aligned.

[0081] When the pressing plate 14 is not pressed, the locking plate 13 extends out of the mounting hole 22 and into the lock hole 220. When the pressing plate 14 is pressed, the locking plate 13 retracts from the lock hole 220.

[0082] When assembling the electrical equipment 1000, the battery device 100 is pushed into the battery cavity 210 through the opening of the housing 200. When the battery device 100 is fully contained in the battery cavity 210, the locking plate 13 of the latch 10 extends into the lock hole 220, locking the battery device 100 to the housing 200. To unlock, press the pressing plate 14 of the latch 10, causing the locking plate 13 to retract from the lock hole 220 and into the housing 21 and mounting hole 22, allowing the battery device 100 to be pulled out of the battery cavity 210, thus disassembling the battery device 100.

[0083] In the embodiment where the locking plate 13 of the latch 10 has a guide surface 131 and a limiting surface 132, during the process of the battery device 100 being pushed into the battery cavity 210, the guide surface 131 first contacts and slides relative to the housing 200. The housing 200 presses the guide surface 131, causing the locking plate 13 to retract into the cavity 21 and the mounting hole 22. The elastic plate 12 elastically deforms. When the mounting hole 22 aligns with the lock hole 220, the elastic plate 12 rebounds, and the locking plate 13 extends out of the mounting hole 22 and into the lock hole 220 again, thus achieving locking. That is, during assembly, locking can be automatically achieved without manually pressing the pressing plate 14.

[0084] The enclosure 200 may also enclose other chambers, such as the electrical chamber 230, which can be used to house various electrical devices without limitation.

[0085] The electrical device 1000 of this utility model adopts the battery device 100 of this utility model. The battery device 100 adopts the latch 10 of this utility model. The latch 10 forms a cantilever structure by setting an elastic plate 12. The elastic tension of the elastic plate 12 can achieve automatic locking. By setting a pressing plate 14, simple pressure can be applied to the pressing plate 14 to achieve unlocking. The structure is simple, no professional tools are required, the operation is convenient, the unlocking time can be shortened, and the disassembly efficiency can be improved.
