Description

Technical Field

[0001] The present application relates to the electrical field of low-voltage switches, and is a universal circuit breaker, and in particular to a rotating structure of a cover of a controller in the universal circuit breaker. Background Art

[0002] In the industrial field, controllers are widely used. There are often some operating buttons or detachable modules on the controller. In order to protect these modules and prevent them from being easily operated, some covers are often set to cover the buttons and modules, and such covers are often set in a rotating manner.

[0003] For example, patents such as CN218218039U, CN218384906U, and CN211700130U all involve controller structures of frame circuit breakers, and all include a protective cover. The protective cover is connected to the housing of the controller by rotation, and the buttons and modules to be protected are located under the protective cover. When the buttons and modules of this type of controller need to be operated, the protective cover is rotated open and then used.

[0004] However, the existing protective cover, as shown in the above three patents, has a constant rotation center. Due to the limitation of the side wall of the controller housing (the side wall adjacent to the rotation center), the maximum opening angle of the protective cover is about 90°. Although the user can operate at such an opening angle, the protective cover still hinders the user's operation to a certain extent, which is not very convenient.

[0005] Therefore, how to design a rotating structure of the protective cover that can increase the opening angle as much as possible is also a direction worthy of in-depth research. Summary of the invention

[0006] In view of this, the purpose of the present application is to overcome the deficiencies in the prior art and to provide a rotating structure of a cover, a controller and a universal circuit breaker having advantages such as a larger opening angle.

[0007] The present application provides: a rotating structure of a cover, which includes a cover and a base, a receiving groove is provided on the base, and the cover is used to close the opening of the receiving groove; the receiving groove includes a first groove wall, a second groove wall and a third groove wall, the first groove wall and the second groove wall are arranged opposite to each other and are connected through the third groove wall; the cover is provided with a cylindrical protrusion corresponding to the first groove wall and the second groove wall respectively; the first groove wall and the second groove wall are both provided with a matching groove, one end of the matching groove is arranged adjacent to the third groove wall, and the other end extends in a direction away from the third groove wall; the size of the matching groove in the width direction is consistent with the diameter of the cylindrical protrusion, and the size of the matching groove in the length direction is at least twice the diameter of the cylindrical protrusion; two cylindrical protrusions are respectively inserted into the corresponding matching grooves, and are both rotated and slidably arranged with the matching grooves; when the cover is completely in the receiving groove, the cylindrical protrusion is arranged close to the third groove wall; in the process of the cover from opening to opening to the maximum angle, the cylindrical protrusion rotates and gradually moves away from the third groove wall along the matching groove.

[0008] With this structure, the reason why the opening angle of the prior art is small is that: since the rotation position of the cover is close to the third groove wall, and the rotation center is constant, it will be immediately blocked by the third groove wall after a certain angle of rotation, and the general rotation angle is about 90°. With the above structure, the rotation center will move. In the process of opening the cover, the cylindrical protrusion will rotate and gradually move away from the third groove wall along the matching groove. Under the same third groove wall structure, the cover opening angle in this cover rotation structure will be greater than the structure with a constant rotation center. Having a larger opening angle will be beneficial to users and improve user experience.

[0009] In some embodiments of the present application, the dimension of the matching groove in the length direction is at least 3.5 times the diameter of the cylindrical protrusion, and the maximum opening angle of the cover is greater than 150°.

[0010] By adopting this structure, the moving distance of the rotation center is further increased, which will allow the cover to have a larger opening angle, for example, an angle of more than 150°.

[0011] In some embodiments of the present application, the accommodating groove also includes a groove bottom, and the first groove wall, the second groove wall and the third groove wall are all walls arranged around the groove bottom; a first rib is arranged on the groove bottom close to the first groove wall and the second groove wall, and the upper surface of the first rib is a part of the matching groove wall; an avoidance groove is arranged on the upper surface of the first rib, and the avoidance groove is located at one end of the matching groove away from the third groove wall, and the avoidance groove is used to accommodate the corners of the cover near the cylindrical protrusion.

[0012] With this structure, the avoidance groove is designed to accommodate the corners of the cover.

[0013] In some embodiments of the present application, the upper surface of the first rib includes a straight section, a transition section and a sunken section, the straight section is higher than the sunken section, the transition section is connected between the straight section and the sunken section, and the transition section is an inclined surface or an arc surface; during the process of the cover rotating to the maximum angle or the cover rotating back from the maximum angle, there is an interference fit between the corners of the cover near the cylindrical protrusion and the transition section.

[0014] The use of such a transition portion and the corner of the cover has an interference fit during the process of opening and closing the cover, which can have a certain retention effect. For example, when the cover is at the maximum opening angle, if the cover is accidentally touched and flipped back, this interference fit can hold the cover. Similarly, when the cover is accidentally opened, the interference fit can also be used to hold it before the cover reaches the maximum opening angle. The above-mentioned interference fit will not make the cover unusable. When the cover reaches the interference fit, it only needs to be forced to pass the interference fit position, and the cover can continue to rotate.

[0015] In some embodiments of the present application, a through hole is formed on the cover, a protrusion is provided at the bottom of the groove, and a hanging hole is formed on the protrusion; when the cover is in the receiving groove, the protrusion passes through the through hole, so that the hanging hole is exposed outside the cover.

[0016] With this structure, the hanging hole can be padlocked or sealed, thereby improving safety performance.

[0017] In some embodiments of the present application, a sinking groove is provided on the upper surface of the cover, and the sinking groove is provided around the through hole. When the cover is in the receiving groove, the sinking groove is connected to the hanging hole.

[0018] Adopting this structure and utilizing the design of the sinking groove will make it easier to set the padlock or the lead seal.

[0019] In some embodiments of the present application, the accommodating groove includes a fourth groove wall, which is arranged opposite to the third groove wall; the covering cover includes a rotating shaft end and a movable end away from one end of the rotating shaft end, and the cylindrical protrusion is located on the rotating shaft end; a barb is provided on the movable end, and a card slot is provided on the fourth groove wall, and the barb and the card slot form a snap connection.

[0020] By adopting this structure, the cover and the receiving groove can be buckled together, thereby improving the stability of the cover.

[0021] In some embodiments of the present application, the matching groove is a waist-shaped groove; and / or the cover is transparent.

[0022] A controller comprises a controller housing and the above-mentioned rotating structure of a cover; the base is the controller housing, and buttons and / or knobs and / or pluggable modules are arranged in the receiving groove.

[0023] With the above structure, the rotation center will move. During the process of opening the cover, the cylindrical protrusion will rotate and gradually move away from the third groove wall along the matching groove. Under the same structure of the third groove wall, the opening angle of the cover in this rotation structure of the cover will be greater than the structure with a constant rotation center. Users will be able to better operate buttons, knobs, modules, etc. to enhance user experience.

[0024] A universal circuit breaker, comprising the above-mentioned controller. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0039] like Figure 1-Figure 8As shown, an embodiment of the present application provides a rotation structure of a cover 100 , which includes a cover 100 and a base 200 .

[0040] The base 200 is provided with a receiving groove 201, and the receiving groove 201 includes a first groove wall 201a, a second groove wall 201b, a third groove wall 201c, a fourth groove wall 201d and a groove bottom 201e. The first groove wall 201a, the second groove wall 201b, the third groove wall 201 and the fourth groove wall 201d are all walls surrounding the groove bottom 201e, and the first groove wall 201a and the second groove wall 201b are arranged opposite to each other and are connected through the third groove wall 201c and the fourth groove wall 201d.

[0041] The cover 100 is made of a transparent material and is rotatably disposed at the opening position of the receiving groove 201. The cover 100 is used to close the receiving groove 201. The cover 100 has a closed state and an open state. In the closed state, the cover 100 is inside the receiving groove 201 to close the receiving groove 201. In the open state, the cover 100 is rotated out of the receiving groove 201 to the maximum position, so that the opening of the receiving groove 201 is exposed.

[0042] Here, there is both a rotation setting and a sliding setting between the cover 100 and the receiving groove 201. Specifically, the cover 100 includes a shaft end 100a and a movable end 100b. The shaft end 100a has cylindrical protrusions 100a0 protruding to both sides, and the cross-sectional shape of the cylindrical protrusion 100a0 here is circular. The two cylindrical protrusions 100a0 here correspond to the first groove wall 201a and the second groove wall 201b respectively, and a matching groove 201f is provided on the first groove wall 201a and the second groove wall 201b. The matching groove 201f here is arranged near the third groove wall 201c. The length direction of the matching groove 201f here is consistent with the length direction of the first groove wall 201a and the second groove wall 201b, and the width direction of the matching groove 201f is consistent with the depth direction of the receiving groove 201. The matching groove 201f here is a waist-shaped groove.

[0043] Here, the cylindrical protrusion 100a0 extends into the corresponding matching groove 201f, and the length of the matching groove 201f is greater than the diameter of the cylindrical protrusion 100a0, so the cylindrical protrusion 100a0 can move along the length direction of the matching groove 201f. The width direction of the matching groove 201f is consistent with the diameter of the cylindrical protrusion 100a0.

[0044] When the cover 100 is not opened, the cylindrical protrusion 100a0 is located at one end of the matching groove 201f, and the end is adjacent to the third groove wall 201c. When the cover 100 is opened, the cylindrical protrusion 100a0 rotates and moves along the length direction of the matching groove 201f, away from the third groove wall 201c.

[0045] In this way, the cover 100 can have a larger opening angle.

[0046] Here, the length dimension of the matching groove 201f is at least 3.5 times the diameter of the cylindrical protrusion 100a0, and the maximum opening angle of the cover 100 is above 150°. Of course, the relationship between the length dimension of the matching groove 201f and the diameter of the cylindrical protrusion 100a0 is not limited to this multiple relationship. As long as it is more than 2 times, the cover 100 has a larger opening angle compared with the prior art, and can also improve the user experience.

[0047] Here, the groove bottom 201e also has a first rib 201e0, and there are two first ribs 201e0, which are respectively near the first groove wall 201a and the second groove wall 201b. The upper surface of the first rib 201e0 is part of the groove wall of the matching groove 201f. It can be said that the lower groove wall of the matching groove 201f is the upper surface of the first rib 201e0. Here, the upper surface of the first rib 201e0 has an avoidance groove 201e1, which is located at one end of the matching groove 201f away from the third groove wall 201c. The avoidance groove 201e1 here can accommodate the corner 100c of the cover 100, and the corner 100c here is the corner 100c near the columnar protrusion 100a0.

[0048] Here, the upper surface of the first rib 201e0 includes a straight section 201e2, a transition section 201e3 and a sinking section 201e4. The height of the straight section 201e2 is higher than that of the sinking section 201e4. The transition portion connects the straight section 201e2 with the sinking section 201e4. The avoidance groove 201e1 is formed by the transition section 201e3 and the sinking section 201e4. In this embodiment, the transition section 201e3 is an inclined surface. During the rotation of the cover 100, the rotation here includes the transition of the cover 100 from the open state to the closed state, and also includes the transition from the closed state to the open state. During this rotation process, the corner 100c of the cover 100 located near the columnar protrusion 100a0 will be pressed against the transition section 201e3, that is, there is an interference fit between the corner 100c and the transition section 201e3. Of course, this interference fit can be overcome by pushing the cover 100 with a little force, so that the cover 100 continues to rotate. Of course, the transition section 201e3 here can also be a curved surface in addition to the inclined surface. The above-mentioned transition section 201e3 can achieve a certain holding effect. The use of such transition section and the corner 100c of the cover 100 has an interference fit during the process of opening and closing the cover 100, which can achieve a certain holding effect. For example, when the cover 100 is at the maximum opening angle, that is, when the cover 100 is accidentally touched and turned back, the interference fit can hold the cover 100. Similarly, when the cover 100 is accidentally opened, the interference fit can also be used to hold it before the cover 100 reaches the maximum opening angle.

[0049] In order to enable the cover 100 to be locked with the receiving groove 201 in the closed state, a locking groove 201d0 is provided on the fourth groove wall 201d of the receiving groove 201, and a barb 100b0 is provided on the movable end 100b of the cover 100, and the barb 100b0 and the locking groove 201d0 are buckled. The number of the locking groove 201d0 and the barb 100b0 is two.

[0050] The bottom 201e of the groove has a protrusion 201e5 that passes through the receiving groove 201, and a hanging hole 201e6 is formed on the protrusion 201e5. The cover 100 is provided with a through hole 100d, and the protrusion 201e5 passes through the through hole 100d so that the hanging hole 201e6 is exposed outside the cover 100, so as to facilitate padlocking or lead sealing. Here, the upper surface of the cover 100 has a sinking groove 100e, and the sinking groove 100e surrounds the through hole 100d, so that the hanging hole 201e6 is connected with the receiving sinking groove 100e, so as to facilitate padlocking or lead sealing.

[0051] The above-mentioned rotating structure can be applied to a controller, such as a controller for a universal circuit breaker. The base here is the controller housing of the controller, and a through hole 2010 for buttons, knobs, pluggable modules and other components is provided in the receiving slot 201. By opening the cover 100, the user can perform corresponding operations.

[0052] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without contradiction.
