Description

Technical Field

[0001] This utility model relates to the field of brackets, and in particular to a connection structure and bracket. Background Technology

[0002] In today's society, electronic devices have permeated every aspect of people's lives. To facilitate the use of electronic devices, people often use stands to support mobile phones and other electronic devices. To further enhance the user experience and meet the needs of different scenarios, stands are usually connected to quick-change connection structures. These connection structures link the stands and electronic devices, providing both secure fixation and convenient, quick access to the devices.

[0003] In existing technologies, quick-change connection structures often use a rotary snap-fit ​​method for connection, which has problems such as low reliability and abnormal noise. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a connection structure that is highly reliable and less prone to generating abnormal noise.

[0005] This utility model also proposes a bracket including the above-mentioned connection structure.

[0006] The connection structure according to the first aspect of the present invention includes:

[0007] Base;

[0008] The connecting part has one end abutting against the base and is provided with a connecting hole. The side wall of the connecting hole is provided with a connecting slope. Along the direction away from the base, the distance from the connecting slope to the center line of the connecting part increases.

[0009] The snap-fit ​​part is slidably disposed on the base. During the sliding process, the snap-fit ​​part can extend into the connection hole and abut against the connection slope, and can also exit the connection hole along the connection slope.

[0010] An adjustment part is rotatably mounted on the base and abuts against the locking part. When the adjustment part rotates in a set direction, it can drive the locking part to exit the connecting hole along the connecting slope.

[0011] The connection structure according to the embodiment of this utility model has at least the following beneficial effects:

[0012] In this embodiment, the connection structure features a connecting ramp on the connecting part, inclined relative to its centerline. A locking part and an adjusting part are slidably mounted on the base. During sliding, the locking part can extend into the connecting hole to abut against the connecting ramp, thereby locking the connecting part relative to the base. By rotating the adjusting part, the locking part can be moved out of the connecting hole along the connecting ramp to unlock the connecting part. The locking part can move from the unlocked position to the locked position by reversing the adjusting part or by setting up a separate reset structure. This embodiment locks the connecting part by using the locking part abutting against the connecting ramp, which reduces the connection gap between the connecting part and the base, ensuring a reliable connection and reducing the likelihood of abnormal noise. Furthermore, when the locking part unlocks the connecting part, it needs to move along the connecting ramp to exit the connecting hole, requiring not only a force perpendicular to the centerline of the connecting part but also a force parallel to the centerline of the connecting part. This makes the connection structure less prone to loosening during use and ensures high reliability.

[0013] According to some embodiments of the present invention, the rotation axis of the adjusting part is parallel to the center line of the connecting part, one of the adjusting part and the locking part forms a transmission surface, and the other abuts against the transmission surface. Along the set direction, the distance from the transmission surface to the rotation axis of the adjusting part increases, so that when the adjusting part rotates along the set direction, it can apply an inward force perpendicular to the rotation axis of the adjusting part to the locking part.

[0014] According to some embodiments of the present invention, one of the adjusting part and the snap-fit ​​part is provided with a transmission groove, and the other is provided with a transmission column. The transmission surface is formed on the side wall of the transmission groove, and the transmission column is inserted into the transmission groove and abuts against the transmission surface.

[0015] According to some embodiments of the present invention, the connection structure further includes:

[0016] An elastic reset part is connected between the base and the snap-fit ​​part, and is used to apply an elastic force to the snap-fit ​​part so that the snap-fit ​​part can extend into the connection hole and abut against the connection slope.

[0017] According to some embodiments of this utility model, the base defines a mounting cavity, and a through guide groove is provided on the side of the mounting cavity near the connecting part. The extending direction of the guide groove forms an angle with the center line of the connecting part. The snap-fit ​​part includes:

[0018] The main body is disposed within the mounting cavity and abuts against the adjustment part;

[0019] A locking block is connected to the main body and slidably inserted into the guide groove, and the locking block is used to abut against the connecting inclined surface.

[0020] According to some embodiments of the present invention, the base defines a mounting cavity, a mounting shaft is disposed within the mounting cavity, a limiting groove is provided on the periphery of the mounting cavity, and the adjusting part includes:

[0021] A rotating part, which is rotatably mounted on the mounting shaft;

[0022] An operating part is connected to the rotating part and extends through the limiting groove to the outside of the base;

[0023] The limiting groove is used to limit the rotation angle of the adjusting part.

[0024] According to some embodiments of the present invention, one of the connecting inclined surface and the snap-fit ​​part is provided with a positioning protrusion, and the other is provided with a positioning groove. When the snap-fit ​​part abuts against the connecting inclined surface, the positioning protrusion is embedded in the positioning groove to restrict the rotation of the connecting part relative to the base.

[0025] According to some embodiments of the present invention, the center line of the connecting hole is collinear with the center line of the connecting part, and the base is provided with a boss, which is inserted into the connecting hole.

[0026] According to some embodiments of the present invention, one of the base and the connecting part is provided with a first magnetic attraction part, and the other is provided with a second magnetic attraction part, wherein the second magnetic attraction part is used to magnetically connect with the first magnetic attraction part.

[0027] The bracket according to a second aspect embodiment of the present invention includes the connection structure described in the first aspect embodiment.

[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0045] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0046] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0047] Connection structures are commonly used to connect parts, allowing one part to be connected to or separated from another, thus achieving the purpose of quickly connecting or separating two parts. For example, connection structures can be used to fix a mobile phone to a desktop, car cockpit, bicycle handlebars, etc.

[0048] Reference Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a connection structure, which includes: a base 100, a connecting part 200, a snap-fit ​​part 300, and an adjusting part 400.

[0049] One end of the connecting part 200 abuts against the base 100, and a connecting hole 201 is provided at the end of the connecting part 200 abutting against the base 100. A connecting inclined surface 202 is provided on the side wall of the connecting hole 201. Along the direction away from the base 100, the distance from the connecting inclined surface 202 to the center line of the connecting part 200 increases, that is, the connecting inclined surface 202 is inclined relative to the center line of the connecting part 200. It should be noted that the state in which one end of the connecting part 200 abuts against the base 100 refers to the state when the connecting structure is in use. When the connecting structure is not needed, the connecting part 200 can be separated from the base 100.

[0050] The latching part 300 is slidably disposed on the base 100. The sliding direction of the latching part 300 forms an angle with the center line of the connecting part 200. During the sliding process, the latching part 300 can extend into the connecting hole 201 and abut against the connecting inclined surface 202, and can also exit the connecting hole 201 along the connecting inclined surface 202. When the latching part 300 extends into the connecting hole 201 and abuts against the connecting inclined surface 202, it is in the locked position, which can lock the connecting part 200 relative to the base 100. When the latching part 300 exits the connecting hole 201 along the connecting inclined surface 202, it is in the unlocked position, which can release the locking of the connecting part 200, so that the connecting part 200 can be separated from the base 100.

[0051] The adjustment part 400 is rotatably mounted on the base 100 and abuts against the locking part 300. When the adjustment part 400 rotates in a set direction, it can drive the locking part 300 to exit the connection hole 201 along the connection slope 202, thereby unlocking the connection part 200 relative to the base 100. Obviously, the set direction can be clockwise or counterclockwise.

[0052] The connection structure of this utility model embodiment includes a connecting inclined surface 202 on the connecting part 200, which is inclined relative to its centerline. A locking part 300 and an adjusting part 400 are slidably disposed on the base 100. During sliding, the locking part 300 can extend into the connecting hole 201 to abut against the connecting inclined surface 202, thereby locking the connecting part 200 relative to the base 100. By rotating the adjusting part 400, the locking part 300 can be driven to exit the connecting hole 201 along the connecting inclined surface 202 to unlock the connecting part 200. The locking part 300 can move from the unlocked position to the locked position by rotating in the opposite direction. The adjustment part 400 or a separate reset structure can be used to achieve this. The locking of the connecting part 200 is achieved by using the snap-fit ​​part 300 to abut against the connecting slope 202, which can reduce the connection gap between the connecting part 200 and the base 100, making the connection reliable and less prone to abnormal noise. In addition, when the snap-fit ​​part 300 unlocks the connecting part 200, it needs to move along the connecting slope 202 to the exit connecting hole 201. This requires not only a force perpendicular to the center line of the connecting part 200, but also a force parallel to the center line of the connecting part 200, making the connection structure less prone to loosening during use and ensuring high reliability.

[0053] It is conceivable that the base 100 can be used to provide mounting support for the connecting part 200, the snap-fit ​​part 300, the adjusting part 400, etc., and can also be used to connect other components, such as brackets fixed to a desktop or bicycle handlebars. A threaded hole can be provided on the side of the base 100 away from the connecting part 200 to connect other components. The connecting part 200 can be used to connect devices such as mobile phones and tablets. For example, adhesive can be applied to the side of the connecting part 200 away from the base 100 to connect mobile phones or tablets.

[0054] It is conceivable that the number of snap-fit ​​parts 300 can be three, four or more, and only one connecting hole 201 can be provided, with the center line of the connecting hole 201 being collinear with the center line of the connecting part 200. The connecting slope 202 can be a curved surface or a plane. Multiple connecting holes 201 can also be provided, corresponding one-to-one with the snap-fit ​​parts 300.

[0055] It is conceivable that when the adjusting part 400 rotates in the set direction, a force can be applied to the locking part 300 in the direction extending away from the connecting part 200 along the center line of the connecting part 200, so as to drive the locking part 300 out of the connecting hole 201 along the connecting slope 202. Alternatively, a force can be applied to the locking part 300 in the direction extending away from the connecting slope 202 perpendicular to the center line of the connecting part 200, so as to drive the locking part 300 out of the connecting hole 201 along the connecting slope 202. Of course, other forms of force application are also possible.

[0056] In some embodiments of this utility model, reference is made to Figures 1 to 4 As shown, the rotation axis of the adjusting part 400 is parallel to the center line of the connecting part 200. One of the adjusting part 400 and the locking part 300 has a transmission surface 401, and the other abuts against the transmission surface 401. Along the set direction, the distance from the transmission surface 401 to the rotation axis of the adjusting part 400 increases, so that when the adjusting part 400 rotates in the set direction, it can apply an inward force perpendicular to the rotation axis of the adjusting part 400 to the locking part 300, and drive the locking part 300 to exit the connecting hole 201 along the connecting slope 202.

[0057] It is understandable that when the adjusting part 400 rotates in the set direction, the locking part 300 will also tend to rotate in the set direction. However, the locking part 300 is slidably mounted on the base 100 and will not rotate with the adjusting part 400 in the set direction. Furthermore, since the distance from the transmission surface 401 to the rotation axis of the adjusting part 400 in the set direction increases, when the adjusting part 400 rotates in the set direction, it can drive the locking part 300 to move towards the rotation center of the adjusting part 400 in a direction perpendicular to the rotation axis of the adjusting part 400, thereby driving the locking part 300 to exit the connecting hole 201 along the connecting inclined surface 202.

[0058] In a further embodiment, one of the adjusting part 400 and the snap-fit ​​part 300 is provided with a transmission groove 402, and the other is provided with a transmission column 301. The transmission surface 401 is formed on the side wall of the transmission groove 402. The center line of the transmission column 301 is parallel to the rotation axis of the adjusting part 400. The transmission column 301 is inserted into the transmission groove 402 and abuts against the transmission surface 401. By providing the transmission groove 402 to form the transmission surface 401, the processing is convenient.

[0059] When the transmission groove 402 is disposed on the adjusting part 400, such as Figure 4 As shown, the transmission groove 402 has a transmission surface 401 formed on the side wall of the transmission column 301 away from the rotation center of the adjustment part 400. When the transmission groove 402 is provided on the snap-fit ​​part 300 (not shown in the figure), the transmission groove 402 has a transmission surface 401 formed on the side wall of the transmission column 301 near the rotation center of the adjustment part 400.

[0060] In some specific embodiments, such as Figure 4 and Figure 5 As shown, the transmission column 301 is disposed on the snap-fit ​​portion 300, and the transmission groove 402 is disposed on the adjustment portion 400. The transmission groove 402 has a transmission surface 401 formed on the side wall of the transmission column 301 away from the rotation center of the adjustment portion 400. The transmission groove 402 extends through the adjustment portion 400 along the extension direction of the rotation axis of the adjustment portion 400 to avoid hindering the movement of the transmission column 301 along the extension direction of the center line of the connecting portion 200.

[0061] It is conceivable that the movement of the locking part 300 from the unlocked position to the locked position can be achieved by rotating the adjusting part 400 in the reverse direction or by setting up a separate reset structure.

[0062] For example, by adjusting the locking part 300 from the unlocked position to the locked position, the number of transmission surfaces 401 can be set to two and parallel to each other, based on the above embodiment, and the transmission column 301 abuts between the two transmission surfaces 401.

[0063] For example, in some embodiments of this utility model, such as Figure 2 and Figure 7 As shown, the connection structure also includes an elastic reset part 500, which is connected between the base 100 and the snap-fit ​​part 300. The elastic reset part 500 is used to apply an elastic force to the snap-fit ​​part 300 so that the snap-fit ​​part 300 can extend into the connection hole 201 and abut against the connection slope 202. By setting the elastic reset part 500, the snap-fit ​​part 300 can be automatically reset from the unlocked position to the locked position. The user only needs to operate the adjustment part 400 when unlocking the connection part 200, making the operation more convenient and faster.

[0064] In some specific embodiments, the elastic reset portion 500 applies a force to the snap-fit ​​portion 300 in a direction perpendicular to the center line of the connecting portion 200, close to the connecting inclined surface 202.

[0065] It is understandable that when the elastic reset part 500 drives the locking part 300 to reset from the unlocked position to the locked position, the locking part 300 can also drive the adjustment part 400 to reset together. Taking the adjustment part 400 having a transmission groove 402 and the locking part 300 having a transmission column 301 as an example, when the user rotates the adjustment part 400 in a set direction, the adjustment part 400 is the active force-applying component, applying force to the transmission column 301 through the transmission surface 401 in the transmission groove 402, thereby driving the locking part 300 to move from the locked position to the unlocked position. When the user removes the external force on the adjustment part 400, the elastic reset part 500, as the active force-applying component, drives the locking part 300 to move from the unlocked position to the locked position. At this time, the transmission column 301 of the locking part 300, as the active force-applying component, applies force to the transmission surface 401 in the transmission groove 402, thereby causing the adjustment part 400 to rotate and reset.

[0066] It is conceivable that the elastic reset part 500 can be a tension spring, a compression spring, or other elastic structure that meets the requirements.

[0067] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the base 100 includes a body 104 and a cover 105. The body 104 has a recessed cavity. The cover 105 is disposed near the connecting part 200 and connected to the body 104. The body 104 and the cover 105 enclose each other to form a mounting cavity. The mounting cavity can be used to install components such as the snap-fit ​​part 300, the adjustment part 400, and the elastic reset part 500 to improve the aesthetics of the connection structure and also to provide a certain degree of protection for each component.

[0068] For example, the mounting cavity can be used to mount the snap-fit ​​portion 300. In some embodiments of this invention, reference is made to... Figure 1 , Figure 2 and Figure 5 As shown, a through guide groove 101 is provided on the cover 105. The guide groove 101 communicates with the mounting cavity. The extension direction of the guide groove 101 forms an angle with the center line of the connecting part 200, that is, the guide groove 101 is inclined relative to the extension direction of the center line of the connecting part 200. In addition, along the extension direction of the guide groove 101, the projection of the guide groove 101 at least partially coincides with the connecting inclined surface 202. The locking part 300 includes a main body 302 and a locking block 303. The main body 302 is disposed in the mounting cavity and abuts against the adjusting part 400. The locking block 303 is connected to the main body 302 and slides through the guide groove 101, thereby sliding the locking part 300 onto the base 100. When the locking block 303 slides along the guide groove 101, it can extend into the connecting hole 201 and abut against the connecting inclined surface 202 to lock the connecting part 200.

[0069] It is conceivable that there can be multiple guide grooves 101, each corresponding to a snap-fit ​​part 300.

[0070] For example, the mounting cavity can be used to mount the snap-fit ​​part 300 while simultaneously mounting the adjustment part 400. In some embodiments of this utility model, refer to... Figure 1 , Figure 2 and Figure 6 As shown, a mounting shaft 106 is provided at the inner end of the main body 104, and a limiting groove 107 extending circumferentially along the mounting shaft 106 is provided on the periphery of the main body 104. The two opposite ends of the limiting groove 107 along the circumferential direction of the mounting shaft 106 are closed ends. The adjustment part 400 includes a turntable 403 and an operating handle 404. The turntable 403 has a hole for rotatably mounting on the mounting shaft 106. The operating handle 404 is connected to the turntable 403 and extends through the limiting groove 107 to the outside of the base 100. Obviously, since the two opposite ends of the limiting groove 107 along the circumferential direction of the mounting shaft 106 are closed ends, the movement of the operating handle 404 can be restricted to limit the rotation angle of the adjustment part 400. The fact that the operating handle 404 extends through the limiting groove 107 to the outside of the base 100 makes it convenient for the user to rotate the adjustment part 400, making operation convenient.

[0071] For example, the elastic reset part 500 can also be installed simultaneously with the mounting cavity mounting snap-fit ​​part 300. In some embodiments of this utility model, refer to... Figure 1 , Figure 2 and Figure 7 As shown, the elastic reset part 500 adopts a compression spring; the inner end of the cover 105 is provided with a mounting base 108, the mounting base 108 is provided with a first mounting post 109, the main body 302 has an extension part 305, the extension part 305 extends to the side of the mounting base 108 away from the center line of the connecting part 200, and a second mounting post 306 is provided thereon, the two ends of the compression spring are respectively sleeved on the first mounting post 109 and the second mounting post 306, so as to apply an elastic force to the main body 302 along the extension direction of the center line of the connecting part 200 and close to the connecting inclined surface 202.

[0072] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 and Figure 5 As shown, one of the connecting slope 202 and the snap-fit ​​part 300 is provided with a positioning protrusion 203, and the other is provided with a positioning groove 304. When the snap-fit ​​part 300 abuts against the connecting slope 202, the positioning protrusion 203 is embedded in the positioning groove 304 to restrict the rotation of the connecting part 200 relative to the base 100, thereby improving the connection stability of the connection structure. For example Figure 2 In the middle, the connecting inclined surface 202 is provided with positioning protrusions 203 corresponding to the number of snap-fit ​​parts 300, and the snap-fit ​​part 300 is provided with positioning grooves 304.

[0073] Furthermore, in order to facilitate the alignment and cooperation between the positioning protrusion 203 and the positioning groove 304, indicator marks can be provided on the outer periphery of the base 100 and the outer periphery of the connecting part 200 respectively. When the indicator marks on the base 100 are aligned with the indicator marks on the connecting part 200, the positioning protrusion 203 can be aligned with the positioning groove 304.

[0074] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, a connecting hole 201 is provided, and the center line of the connecting hole 201 is collinear with the center line of the connecting part 200. The base 100 is provided with a boss 102, which is inserted into the connecting hole 201, thereby limiting the relative displacement between the connecting part 200 and the base 100 in a direction perpendicular to the center line of the connecting hole 201, and reducing the force on the snap-fit ​​part 300 during the use of the connecting structure. In some specific embodiments, the boss 102 is provided on the cover 105 of the base 100.

[0075] In some embodiments of this utility model, reference is made to Figure 2 As shown, one of the base 100 and the connecting part 200 is provided with a first magnetic attraction part 103, and the other is provided with a second magnetic attraction part 204. The second magnetic attraction part 204 is used to magnetically connect with the first magnetic attraction part 103 to improve the connection stability between the connecting part 200 and the base 100. The first magnetic attraction part 103 and the second magnetic attraction part 204 can be magnets.

[0076] The following describes the usage method of the connection structure according to one embodiment of the present invention. In use, the adjustment part 400 is rotated. During the rotation of the adjustment part 400, force is applied to the transmission column 301 through the transmission surface 401, thereby applying force to the locking part 300, causing the locking part 300 to slide in the guide groove 101 toward the inside of the base 100, so that the locking part 300 moves to the unlocked position. At this time, the elastic reset part 500 (compression spring) is compressed, and then the connecting part 200 is pressed against the base 100, so that the boss 102 is inserted into the connecting hole 201. At the same time, the base 100 and the connecting part 200 are aligned by the indicator mark. Finally, the external force is removed. As the external force disappears, the elastic reset part 500 is reset, driving the locking part 300 to extend into the connecting hole 201 and abut against the connecting inclined surface 202, thereby locking the connecting part 200.

[0077] The present invention also proposes a bracket, which includes the connection structure of the first aspect embodiment described above. A threaded hole can be provided on the side of the base 100 away from the connecting part 200 for connecting other components, and adhesive can be applied to the side of the connecting part 200 away from the base 100 for connecting devices such as mobile phones or tablets.
