Description

Technical Field

[0001] This utility model relates to the field of cover-closing mechanisms, and in particular to a cover-closing mechanism and an inverter. Background Technology

[0002] To achieve automatic opening and closing, the lid-closing mechanism is generally equipped with a torsion spring. In this case, the torsion spring stores a certain amount of elastic potential energy during rotation. Thus, when the lid is rotated to a certain angle position, the rear stroke of the lid can be automatically opened or closed. However, due to the use of a torsion spring structure, the number of parts increases, and the corresponding products are more complicated in the production and assembly process. Utility Model Content

[0003] Therefore, it is necessary to provide a covering mechanism and an inverter to address the problems in the existing technology.

[0004] A closing mechanism, characterized in that it comprises a main body and a cover, the main body having a rotating groove, the cover having a rotating shaft, the main body and the cover being rotatably connected via the rotating shaft and the rotating groove, the upper side of the main body having an elastic sheet, the cover having a top surface and a bottom surface that closes with the main body, and a side surface corresponding to the elastic sheet between the top surface and the bottom surface, the side surface being an inclined surface, the connection points of the inclined surface with the top surface and the bottom surface being an upper connecting arc surface and a lower connecting arc surface, respectively; when the cover rotates on the upper side of the main body, the lower connecting arc surface abuts against the upper side surface of the main body, the feeding connecting arc surface abuts against the elastic sheet; when the upper connecting arc surface abuts against the elastic sheet near the top surface, the cover automatically opens; when the upper connecting arc surface abuts against the elastic sheet near the side surface, the cover automatically closes.

[0005] In one embodiment, the side of the elastic sheet that abuts against the cover is the abutting surface, and when the cover is closed, the distance between the abutting surface and the cover is 0.15mm-0.25mm.

[0006] In one embodiment, the bottom of the elastic sheet is connected to the main body, and the other sides of the elastic sheet, except for the bottom and the contact surface, are provided with deformation gaps with the main body.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] like Figures 1 to 5 As shown, a closing mechanism is characterized by comprising a main body 1 and a cover 2. The main body 1 is provided with a rotating groove 11, and the cover 2 is provided with a rotating shaft 21. The main body 1 and the cover 2 are rotatably connected by the rotating shaft 21 and the rotating groove 11. An elastic sheet 3 is provided on the upper side of the main body 1. The cover 2 includes a top surface 22 and a bottom surface 23 that closes with the main body 1. Between the top surface 22 and the bottom surface 23, there is also a side surface 24 corresponding to the elastic sheet 3. The side surface 24 is an inclined surface. The connection points between the inclined surface and the top surface 22 and the bottom surface 23 are an upper connecting arc surface 25 and a lower connecting arc surface 26, respectively. When the cover 2 rotates on the upper side of the main body 1, the lower connecting arc surface 26 abuts against the upper side surface 24 of the main body 1, and the feeding connecting arc surface abuts against the elastic sheet 3. When the upper connecting arc surface 25 abuts against the elastic sheet 3 near the top surface 22, the cover 2 automatically opens. When the upper connecting arc surface 25 abuts against the elastic sheet 3 near the side surface 24, the cover 2 automatically closes.

[0020] The main body 1 is equipped with an elastic sheet 3. During the rotation of the cover 2, the cover 2 comes into contact with the elastic sheet 3, and the elastic sheet 3 deforms, thereby applying a force to the cover 2. The cover 2 is equipped with an upper connecting arc surface 25. When the connecting arc surface 25 on the cover 2 abuts against the elastic sheet 3 at different positions, different angles of force can be achieved, thereby controlling the rotation of the rear part of the cover 2's stroke and realizing the automatic closing or opening process of the cover 2. At this time, there is no need to set up a separate torsion spring structure, making the overall structure simpler and improving the user experience.

[0021] During the rotation of the cover 2, the lower connecting arc surface 26 of the cover 2 contacts the upper side surface 24 of the main body 1, thereby ensuring the stability of the cover 2 during rotation.

[0022] At this time, since the automatic rotation of the cover 2 is controlled by the force applied by the elastic sheet 3, the cover 2 needs to contact the elastic sheet 3 during rotation. At this time, the side of the elastic sheet 3 that abuts against the cover 2 is the contact surface. If the cover 2 is too close to the elastic sheet 3 during rotation, the cover 2 will not be able to rotate; if it is too far away, it will not make contact, and even if it does, the elastic sheet 3 will not deform. Therefore, it is necessary to control the distance between the cover 2 and the elastic sheet 3. At this time, when the cover 2 is closed, the distance between the contact surface and the cover 2 is 0.15mm-0.25mm. Specifically, in this embodiment, the distance between the contact surface and the cover 2 is 0.2mm. After setting a certain distance, when the cover 2 is closed, there is a certain distance between the side 24 (contact surface) of the cover 2 and the elastic sheet 3. This way, when the cover 2 first starts to rotate, there is a distance between it and the elastic sheet 3, allowing for convenient rotation.

[0023] Since the external force on the cover 2 is exerted by the elastic sheet 3, the elastic sheet 3 will deform during the opening and closing process of the cover 2 (when it comes into contact with the elastic sheet 3). Therefore, to ensure that the elastic sheet 3 can deform stably, at this time, the bottom of the elastic sheet 3 is connected to the main body 1, and the other sides 24 of the elastic sheet 3, except for the bottom and the contact surface, are provided with deformation gaps to the main body 1. In this way, the elastic sheet 3 is only set together with the main body 1 at its bottom position. The elastic sheet 3 is easy to deform under the action of external force. During the deformation process, it will also exert a force on the cover 2, thereby controlling the automatic closing of the cover 2. At this time, the elastic sheet 3 and the main body 1 are an integral structure, and the whole is made of ABS+PC. In this way, the elastic sheet 3 can undergo a certain deformation during use and can recover its deformation when the external force is removed.

[0024] The cover 2 and the main body 1 are rotatably connected via a rotating shaft 21 and a rotating groove 11. To enable the cover 2 to open and close smoothly during rotation, in this embodiment, the rotating shaft 21 includes a rectangular portion 211, which includes a long side and a short side. An arc-shaped portion 212 is provided on the outer side of the short side, and the two arc-shaped portions 212 are on the same circle centered on the rotating shaft 21. Meanwhile, the rotating groove 11 includes a fan-shaped groove 111 corresponding to the curvature of the arc-shaped portion 212. A recessed portion 112 is provided on the lower side of the fan-shaped groove 111. When the rotating shaft 21 rotates within the rotating groove 11, the arc-shaped portion 212 fits into the fan-shaped groove 111.

[0025] That is, at this time, the cross-section of the rotating shaft 21 is generally racetrack-shaped. The width of the short side of the rotating shaft 21 is smaller than the width of the rotating groove 11 (the diameter of the fan-shaped groove 111 or the width of the recessed part 112), and the length of the recessed part 112 is greater than the diameter of the arc-shaped part 212 of the rotating shaft 21. Thus, the size of the rotating shaft 21 is smaller than the size of the rotating groove 11, and the rotating shaft 21 has a certain distance of movement within the rotating groove 11. During the rotation of the cover 2, the axis of the rotating shaft 21 and the center of the fan-shaped groove 111 are not always in the same position. During the specific rotation process, To enable the rotating shaft 21 to slide and rotate smoothly within the rotating groove 11, in this embodiment, the fan-shaped groove 111 is semi-circular, and the side of the recessed portion 112 is tangent to the arc surface of the fan-shaped groove 111. That is, the inner surface 24 of the rotating groove 11 is smooth, facilitating the free switching of the rotating shaft 21 between the fan-shaped groove 111 and the recessed portion 112.

[0026] During the rotation of the rotating shaft 21, in order for the rotating shaft 21 to be able to move within the rotating groove 11, especially when the cover 2 is rotated to the open state, a small gap (0.2mm) is provided between the top surface 22 of the cover 2 and the elastic sheet 3. Therefore, in this embodiment, when the cover 2 is opened and perpendicular to the main body 1, the distance between the top surface 22 of the cover 2 and the elastic sheet 3 is 0.2mm-0.5mm. Specifically, in this embodiment, the distance between the top surface 22 of the cover 2 and the elastic sheet 3 is 0.4mm. At this time, the cover 2 has a certain amount of room to move, which makes it more convenient to rotate the cover 2 to close.

[0027] In order to ensure that the elastic sheet 3 can provide a certain elasticity and is not easily damaged during deformation, in this embodiment, the thickness of the elastic sheet 3 is 1mm-1.2mm. Specifically, in this embodiment, it is 1.2mm. At this thickness, the elastic sheet 3 can deform when the cover 2 rotates, thereby providing a certain force to the cover 2. Thus, when opening and closing, it can act on the cover 2, causing the cover 2 to rotate automatically.

[0028] The inclined surface of the side 24 of the cover 2 makes it easier to open. The inclination angle of the side 24 of the cover 2 is 18°-25°. Specifically, it is 20° in this embodiment. This inclination angle refers to the angle formed between the side 24 and the elastic side 24 when the cover is closed. When the side 24 of the cover 2 is inclined, during the opening process of the cover 2, the lower connecting arc surface 26 first abuts against the main body 1 and rotates, and then rotates until the inclined side 24 abuts against the main body 1. When external force is applied, the upper connecting arc surface 25 abuts against the main body 1 and rotates. In this way, a buffer is formed between the lower connecting arc surface 26, which makes it easier for the cover 2 to rotate.

[0029] This application also provides another embodiment, including an inverter employing the above-described covering mechanism.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
