By setting the lock head to abut against the first locking part of the lock seat and push the first locking part to rotate, this application can achieve a rolling connection between the lock head and the first locking part during the contact process. This transforms the sliding friction between the lock head and the lock seat in the current door opening and closing process into rolling friction, significantly reducing friction and making it easier to open and close the door. On the one hand, it saves time and effort; on the other hand, it reduces frictional wear of the locking mechanism during the door opening and closing process, effectively improving the service life of the locking mechanism.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0060] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified. In the description of this application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular, for example, the range of included angles from 80° to 100° is considered perpendicular. Similarly, "parallel" means completely parallel or almost completely parallel, for example, the range of completely parallel angles from 10° is considered parallel.

[0061] In related technologies, energy storage cabinets use a locking mechanism to lock the cabinet door to the cabinet body. The locking mechanism works by using the reaction force generated when the lock cylinder rotates and pushes the lock seat to open the cabinet door. This generates significant friction, making it difficult to open and close the door, and sometimes even impossible. Furthermore, due to this high friction, the lock cylinder and lock seat are prone to wear and tear, leading to corrosion and preventing the door from opening and closing properly.

[0062] In view of this, embodiments of this application provide a locking mechanism and an energy storage cabinet, which aim to solve at least one of the above problems.

[0063] Please refer to the following: Figure 1 , Figure 2 and Figure 4 This application provides a locking mechanism, including a lock seat 100 and a lock head 200. The lock seat 100 includes a first locking part 120. The lock head 200 can abut against the first locking part 120 and push the first locking part 120 to rotate.

[0064] In this embodiment, the locking mechanism is configured such that the lock head 200 can abut against and push the first locking part 120 of the lock seat 100 to rotate. This enables the lock head 200 and the first locking part 120 to roll during the contact process, which transforms the sliding friction between the lock head 200 and the lock seat 100 during the current cabinet door 400 opening and closing process into rolling friction. The friction force is greatly reduced, making it easier to open and close the door. On the one hand, it saves time and effort, and on the other hand, it reduces the frictional wear of the locking mechanism during the opening and closing process, effectively improving the service life of the locking mechanism.

[0065] In this application, the locking mechanism is typically used for locking doors such as containers or energy storage cabinets. For example, in an energy storage cabinet, the lock seat 100 is fixed to the cabinet body 300, and the lock head 200 is fixed to the cabinet door 400. The lock seat 100 may have a locking space 110, or the lock seat 100 and the cabinet body 300 may form a locking space 110, which is used to accommodate at least a portion of the lock head 200 when the cabinet door 400 is closed, and the first locking part 120 of the lock seat 100 limits and fixes the lock head 200, maintaining the stability of the locking mechanism.

[0066] It should be noted that when the lock head 200 of this application contacts the first locking part 120, it can push the first locking part 120 to rotate, which is equivalent to the lock head 200 and the first locking part 120 being rolled together. At this time, the first locking part 120 can be rolled as a whole or in part by means of a roller or bearing. Thus, when the lock head 200 contacts the first locking part 120, the movement of the lock head 200 is locked. The contact part between the first locking part 120 and the lock head 200 is in rolling contact with the first locking part 120. Since the rolling friction coefficient is much smaller than the sliding friction coefficient, the friction between the two is significantly reduced during the rotation or movement of the lock head 200. This makes the cabinet door 400 open or close more smoothly and effortlessly.

[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the lock seat 100 includes a base 130, which is connected to the first locking part 120 and forms a locking space 110.

[0068] In this embodiment, the lock seat 100 includes a base 130, which is used to fix the lock seat 100 to the cabinet 300. The base 130 is the basic support structure of the lock seat 100, providing a fixed installation reference for the first locking part 120 and facilitating the stability of the first locking part 120. Simultaneously, the base 130 supports the first locking part 120, creating a gap between the first locking part 120 and the cabinet 300, thereby forming a locking space 110. This allows at least a portion of the lock head 200 to move between the first locking part 120 and the cabinet 300, achieving positioning and limiting of the lock head 200 by the first locking part 120.

[0069] It should be noted that the lock seat 100 in this embodiment of the application is provided with a base 130. At this time, the base 130 and the first locking part 120 can be a separate structure. Compared with the one-piece molded lock seat 100 structure, this is more convenient for production and assembly.

[0070] It is understood that the base 130 of this application can be a U-shaped support frame, with both ends of the U-shaped support frame connected to the first locking part 120 to form a locking space 110. Alternatively, the base 130 of this application can also be two oppositely arranged fixing ears, which can be respectively connected to both ends of the first locking part 120 and then connected to the cabinet 300, thus also forming the locking space 110. The base 130 can be fixed to the cabinet 300 by bolts or other fasteners.

[0071] It is understood that in some embodiments of this application, the first locking part 120 can be rotatably connected to the base 130. In this case, the first locking part 120 can rotate as a whole during the contact with the lock head 200, so that the two can be rolled together during the contact between the lock head 200 and the first locking part 120.

[0072] like Figure 4 and Figure 5 As shown, in some embodiments, the lock head 200 includes a first shaft 210 and a second locking part 220. The second locking part 220 is connected to the periphery of the first shaft 210 and can rotate with the first shaft 210. The second locking part 220 can abut against the first locking part 120.

[0073] In this embodiment, the first shaft 210 rotates to drive the second locking part 220 to rotate. The first locking body can rotate clockwise or counterclockwise, thereby driving the second locking part 220 to approach and abut against the first locking part 120, or away from the first locking part 120. Simultaneously, the rotation of the first shaft 210 provides a driving force to the second locking part 220, ensuring the stability of the second locking part 220 abutting against and pushing the first locking part 120 to rotate; this can be understood as the stability of their rolling connection.

[0074] It should be noted that this application divides the lock head 200 into two parts: a first shaft 210 and a second locking part 220. The first shaft 210 can be located on one side of the lock seat 100, and the second locking part 220 protrudes from the outer periphery of the first shaft 210, thus forming a cam structure. The rotation of the first shaft 210 drives the second locking part 220 to rotate, moving it closer to or further away from the first locking part 120. The rotational driving force generated by the rotation of the first shaft 210 is transmitted to the second locking part 220 through the first shaft 210, reducing force transmission loss and making the limiting and locking actions of the second locking part 220 and the first locking part 120 more synchronized and precise.

[0075] It should be noted that the second locking part 220 is specifically designed to cooperate with the first locking part 120. A rolling adaptation structure (such as an arc surface, roller mounting groove, etc.) can be designed to make the rolling contact between the second locking part 220 and the first locking part 120 smoother, further reducing frictional resistance, thereby making it easier to open and close the door.

[0076] It should also be noted that the first shaft 210 and the second locking part 220 of this application can be an integral connection structure. In this case, the first shaft 210 and the second locking part 220 can be integrally formed, which can ensure the structural strength of the lock head 200 and withstand the reaction force applied by the first locking part 120 to the second locking part 220 during the phase limiting locking process of the first locking part 120 and the second locking part 220 when locking the door, thereby ensuring the service life of the lock head 200. Of course, in this embodiment of the lock head 200, the first shaft 210 and the second locking part 220 can also be connected separately. In this case, the first shaft 210 needs to ensure structural strength to withstand rotational force, and the second locking part 220 needs to withstand not only the rotational driving force of the first shaft 210, but also the reaction force of the first locking part 120. At the same time, the rolling contact between the second locking part 220 and the first locking part 120 will also wear out under long-term use (but the friction is much smaller than that of sliding friction). Therefore, the second locking part 220 can be designed with high strength and high wear resistance to extend the service life of the lock head 200. In addition, the separate design of the first shaft 210 and the second locking part 220 also allows the lock head 200 to continue to be used by simply replacing the second locking part 220 when the second locking part 220 is worn to the point of being unusable, without having to replace the entire lock head 200, thereby reducing spare parts costs and replacement cycles, and further extending the overall service life of the locking mechanism.

[0077] It should also be noted that the second locking part 220 in this application embodiment can be flexibly set in shape, size and position according to the size of the locking space 110, so as to adapt to locking spaces 110 of different sizes or locking strength requirements.

[0078] The operation process of the locking mechanism in this embodiment is as follows: When the locking mechanism is in the unlocked state, the lock head 200 is not in contact with the first locking part 120, specifically as follows: Figure 8 , Figure 9 , Figure 12 and Figure 13 As shown. When the door needs to be locked, rotate the lock head 200, turning the second locking part 220 of the lock head 200 into the locking space 110 until the second locking part 220 passes through the locking space 110 and abuts against the first locking part 120. At this time, the locking mechanism is in the locked state, as shown in the figure. Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown. When it is necessary to open the door, the lock head 200 is rotated in the opposite direction. At this time, the second locking part 220 rotates in the opposite direction and exits from the locking space 110 until the second locking part 220 is no longer in contact with the first locking part 120, thereby unlocking and returning to the unlocked state.

[0079] like Figure 3 As shown, in some embodiments, the first locking part 120 includes a second shaft 121 and a bushing 122. The bushing 122 is movably sleeved on the outside of the second shaft 121 and can rotate around the second shaft 121; the second locking part 220 can abut against the bushing 122.

[0080] In this embodiment, by setting a second shaft 121 and a bushing 122, with the bushing 122 movably sleeved on the outer periphery of the second shaft 121, and the bushing 122 being a cylindrical sleeve, the bushing 122 can rotate outside the second shaft 121. Therefore, when the second locking part 220 rotates with the first shaft 210 and contacts the first locking part 120, the actual second locking part 220 can contact the bushing 122, and the bushing 122 can rotate around the second shaft 121. At this time, there is rolling friction (or relative motion with a low coefficient of friction) between the second locking part 220 and the bushing 122, and between the bushing 122 and the second shaft 121. This further reduces frictional resistance, thereby further reducing the resistance when the lock head 200 rotates, improving the smoothness of the switch cabinet, and effectively solving the problem of difficulty or even hardship in opening and closing the door.

[0081] It should be noted that during the unlocking or locking process of the locking mechanism in this embodiment, rolling friction occurs between the second locking part 220 and the bushing 122, and between the bushing 122 and the second shaft 121. At this time, the bushing 122 serves as the contact medium between the first locking part 120 and the second locking part 220. The rotational characteristics of the bushing 122 can disperse contact stress and avoid excessive local wear.

[0082] In some embodiments, the bushing 122 is a non-metallic sleeve with self-lubricating properties.

[0083] In this embodiment, by setting the bushing 122 as a non-metallic sleeve with self-lubricating properties, the coefficient of friction can be further reduced, and the smoothness of locking and unlocking can be improved.

[0084] It should be noted that the non-metallic bushing 122 of this application has self-lubricating properties. At this time, the low coefficient of friction of the material itself can be used to further reduce the contact resistance between the second locking part 220 and the bushing 122.

[0085] Understandably, self-lubrication eliminates the need for additional lubricants, avoiding the increased friction issues caused by insufficient lubrication in traditional metal components. Especially in environments where locking mechanisms may come into contact with dust and moisture, self-lubricating non-metallic sleeves can maintain a low-friction state for extended periods, thus ensuring smoother and less strenuous unlocking and locking processes.

[0086] It should also be noted that the bushing 122 of this application is made of non-metallic material, which can reduce the wear of the bushing 122 and reduce the risk of corrosion, thus effectively extending its service life.

[0087] In this embodiment, the bushing 122 can be made of non-metallic materials such as polyoxymethylene (POM) and polytetrafluoroethylene (PTFE) that are high in strength, wear-resistant, and have self-lubricating properties.

[0088] like Figure 7 and Figure 9 As shown, in some embodiments, the second locking portion 220 includes a locking surface 221 and a relief surface 222 disposed opposite to each other. The locking surface 221 is an arc surface that is concave toward the direction of the relief surface 222, and the relief surface 222 is an arc surface that is convex toward the direction of the direction of the locking surface 221. Along the direction of the second locking portion 220 away from the first shaft 210, the distance between the locking surface 221 and the relief surface 222 gradually decreases.

[0089] The second locking part 220 of this application is provided with a locking surface 221 and a relief surface 222. The locking surface 221 is a concave curved surface that can abut against the first locking part 120 to cooperate with the first locking part 120 to achieve locking. The relief surface 222 is a convex arc surface. Combined with the fact that the distance between the locking surface 221 and the relief surface 222 gradually decreases along the direction of the second locking part 220 away from the first shaft 210, the relief surface 222 can avoid part of the structure of the lock seat 100, avoid interference, and facilitate the smooth entry of the second locking part 220 of the lock head 200 into the locking space 110 and abut against the first locking part 120 for locking.

[0090] like Figure 7 and Figure 9 As shown, in some embodiments, the locking surface 221 is a concave arc surface, the central axis of the locking surface 221 is parallel to the central axis of the second shaft 121, and the locking surface 221 can be rolledly connected with the first locking part 120.

[0091] In this embodiment, the concave arc-shaped locking surface 221 is parallel to the central axis of the second shaft 121 and the bushing 122. This allows the contact between the second locking part 220 and the bushing 122 to be upgraded from point contact or line contact to a more adaptable arc-shaped contact. This ensures a smooth transition of the contact between the second locking part 220 and the bushing 122 along the tangent of the arc surface, facilitating locking and unlocking of the locking mechanism and avoiding contact jamming or gap fluctuations caused by angular offset, significantly improving the smoothness of the rolling connection. Furthermore, compared to traditional planar locking mechanisms, the arc-shaped locking surface 221 and the bushing 122 mutually constrain each other through their contact surfaces, improving locking stability.

[0092] In addition, the locking surface 221 in this embodiment is a concave arc surface. At this time, the second locking part 220 and the bushing 122 are in contact, which can play a guiding role. When the door is in a nearly closed state, the bushing 122 is located in the concave part of the second locking part 220. At this time, the bushing 122 of the lock head 200 and the lock seat 100 can achieve the limiting and locking function, ensuring the reliability of the closed state.

[0093] Understandably, the concave arc locking surface 221 increases the contact area between the second locking part 220 and the bushing 122 and makes the stress distribution more uniform, thus further reducing wear.

[0094] like Figure 7 and Figure 9 As shown, in some embodiments, the clearance surface 222 is disposed on the side of the second locking part 220 away from the first locking part 120; the end of the clearance surface 222 away from the first shaft 210 is inclined toward the locking surface 221.

[0095] In this embodiment, since the lock head 200 cooperates with the lock seat 100, the lock head 200 can rotate to pass through the locking space 110 of the lock seat 100. If the second locking part 220 is relatively thick, it may not be able to pass through the locking space 110, thus causing a situation where locking is not possible. This application provides a clearance surface 222, and the end of the clearance surface away from the first shaft 210 is inclined towards the locking surface 221. This makes the second locking part 220 form a hook-like structure. As the first shaft 210 rotates, the entire radiation range of the second locking part 220 is relatively reduced, which can avoid the lock seat 100 and other structures, thereby avoiding motion interference between the second locking part 220 and the lock seat 100 and improving the smoothness of the lock head 200 rotation. At the same time, by providing the clearance surface 222, the overall volume of the second locking part 220 is relatively reduced, which can better adapt to narrow installation spaces.

[0096] like Figure 4 , Figure 5 and Figure 10 As shown, in some embodiments, the first shaft 210 includes a first shaft 211 and a second shaft 212, with the second shaft 212 connected to the first shaft 211; a second locking part 220 is connected to the outer periphery of the second shaft 212 and is disposed at the end of the second shaft 212 away from the first shaft 211; wherein the central axis of the first shaft 211 is parallel to and not collinear with the central axis of the second shaft 212, so that the first shaft 210 becomes an eccentric shaft structure.

[0097] In this embodiment of the application, by setting the first shaft 211 and the second shaft 212 to be connected, the central axes of the two are parallel and not collinear, thus forming an eccentric shaft structure of the first shaft body 210. At this time, by utilizing the eccentric characteristics of the first shaft body 210, the rotational lever arm of the second locking part 220 can be increased during the rotation of the lock head 200, thereby reducing the force required for unlocking and locking.

[0098] Specifically, the first shaft 211 is used to connect to the rotation drive end. For example, the first shaft 211 can be connected to the locking rod 500. Rotating the locking rod 500 drives the first shaft 211 to rotate, which in turn drives the second shaft 212 to rotate, and the second shaft 212 then drives the second locking part 220 to rotate. Since the second shaft 212 and the first shaft 211 form an eccentric shaft structure after being connected, the eccentricity of the second shaft 212 during rotation is essentially the lever arm of the locking force. At this time, the lever arm is increased relative to the linear rotating shaft, thereby improving the effort-saving aspect of opening and closing the door.

[0099] like Figure 3 and Figure 11As shown, in some embodiments, the base 130 includes a main body 131, a first support 132, and a second support 133. The main body 131 is spaced apart from the first locking part 120. The first support 132 is connected to the side of the main body 131 near the first locking part 120. The first support 132 is connected to the first locking part 120. The second support 133 is connected to the side of the main body 131 near the first locking part 120 and is spaced apart from the first support 132. The second support 133 is connected to the first locking part 120. The main body 131, the first support 132, the second support 133, and the first locking part 120 form a locking space 110.

[0100] In this embodiment, the base 130 is configured as three parts: a main body 131, a first support 132, and a second support 133. The main body 131 is used to connect to the cabinet 300, specifically through welding or bolt locking. The first support 132 and the second support 133 are connected to the main body 131 and extend to the side of the main body 131 away from the cabinet 300. The first locking part 120 is connected to the first support 132 and the second support 133 to form a locking space 110, creating a relatively stable structure that facilitates the connection between the lock seat 100 and the cabinet 300. Furthermore, the double-support structure of the first support 132 and the second support 133 improves the stability of the first locking part 120, thereby enhancing locking reliability.

[0101] In some embodiments, the main body 131 is integrally connected to the first support 132 and the second support 133, respectively.

[0102] In this embodiment, the main body 131 is integrally connected to the first support 132 and the second support 133, respectively, to form an integral base 130, which simplifies the structure and improves installation convenience. At the same time, eliminating the connection gap improves the overall structural rigidity and deformation resistance, facilitates force transmission and timely force distribution, thereby improving the stability of the base 130.

[0103] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the end of the first support portion 132 away from the main body portion 131 is inclined toward the lock head 200; the end of the second support portion 133 away from the main body portion 131 is inclined toward the lock head 200.

[0104] In this embodiment, by tilting the first support portion 132 and the second support portion 133 toward the direction closer to the lock head 200, on the one hand, it can directly provide clearance space for the second locking portion 220, reducing interference between the second locking portion 220 and the main body portion 131 during the process of the second locking portion 220 entering the locking space 110. On the other hand, it can also reduce the overall height of the lock seat 100 protruding from the outside of the cabinet 300, thereby reducing space occupation.

[0105] Furthermore, the two ends of the first locking part 120 are respectively located at the ends of the first support part 132 and the second support part 133 that are away from the main body part 131. This maximizes the avoidance effect brought about by the inclined arrangement of the first support part 132 and the second support part 133.

[0106] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, further, in some embodiments, the first support portion 132 has a first orthographic projection on the main body portion 131; the second support portion 133 has a second orthographic projection on the main body portion 131; both the first orthographic projection and the second orthographic projection are at least partially located outside the side of the main body portion 131 near the lock head 200.

[0107] In this embodiment, the orthographic projections of the first support portion 132 and the second support portion 133 onto the main body portion 131 are at least partially located outside the side of the main body portion 131 near the lock head 200. This allows the first locking portion 120 to be suspended near the side of the main body portion 131 near the lock head 200, facilitating the rotation of the lock head 200 into the locking space 110 and its engagement with the first locking portion 120. This also reduces interference from the main body portion 131 with the movement of the second locking portion 220 of the lock head 200.

[0108] It should be noted that by setting the first support part 132 and the second support part 133 to extend towards the lock head 200, the vertical distance between the first locking part 120 and the main body part 131 can be compressed, which can further improve the overall structural integration and reduce the space occupied by the locking mechanism.

[0109] like Figure 7 , Figure 10 and Figure 12 As shown, in some embodiments, the first locking portion 120 has a third orthographic projection on the main body portion 131, the third orthographic projection being at least partially located outside the side of the main body portion 131 near the lock head 200.

[0110] In this embodiment of the application, by setting the orthographic projection of the first locking part 120 on the main body 131 to be at least partially outside the main body 131, the effective movement space of the locking space 110 can be further expanded, and the movement interference of the main body 131 on the second locking part 220 can be completely avoided.

[0111] like Figure 10 , Figure 11 and Figure 13 As shown, in some embodiments, the first support portion 132 and the second locking portion 220 are spaced apart, the second support portion 133 and the second locking portion 220 are spaced apart, and the main body portion 131 and the second locking portion 220 are spaced apart.

[0112] In this embodiment, by setting the first support portion 132 and the second support portion 133 to be spaced apart from the second locking portion 220 along the axial direction of the second shaft 121, it is possible to avoid interference between the first support portion 132 and the second support portion 133 and the movement of the second locking portion 220. By setting the main body portion 131 to be spaced apart from the second locking portion 220, it is possible to avoid interference between the main body portion 131 and the movement of the second locking portion 220.

[0113] It should be noted that, along the axial direction of the second shaft 121, the distance between the first support part 132 and the second support part 133 can be much greater than the size of the second locking part 220. In this way, when the solid is deformed, the lock head 200 and the lock seat 100 can still maintain a good assembly relationship and locking relationship, ensuring that the locking mechanism can be unlocked or locked normally.

[0114] Specifically, if the size and space allow, the distance between the first support part 132 and the second support part 133 can be set to be greater than at least 1.5 times the size of the second locking part 220. In this case, on the one hand, assembly errors and size errors can be absorbed, on the other hand, deformation can be absorbed, and the door can be opened and closed normally even when the cabinet 300 is deformed.

[0115] Of course, the distance between the first support portion 132 and the second support portion 133 in this application can be calculated or obtained by simulation based on preset conditions, which will not be described in detail here.

[0116] like Figure 14 and Figure 15 As shown, correspondingly, this application embodiment also provides an energy storage cabinet, including a cabinet body 300, a cabinet door 400, and a locking mechanism as described in any of the foregoing embodiments. The cabinet door 400 is hinged to the cabinet body 300, the lock seat 100 of the locking mechanism is connected to the cabinet body 300, the lock head 200 of the locking mechanism is rotatably connected to the side of the cabinet door 400 away from the cabinet body 300, and the lock head 200 is detachably and rollingly connected to the lock seat 100 to open or close the cabinet door 400.
