Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories, and in particular to a bracket that opens and closes smoothly. Background Technology

[0002] With the continuous development of technology, portable mobile digital devices such as smartphones, tablets, and e-readers have become indispensable necessities in people's lives and work. Taking smartphones as an example, people can use their phones to browse the web, watch videos, read novels, take photos, and perform other operations anytime, anywhere. However, holding a phone for a long time can easily lead to hand fatigue and the phone falling off the hand. There is also a need to place the phone in a fixed position. Therefore, supporting products such as ring holders have emerged.

[0003] A ring holder is a common accessory for electronic devices. In addition to allowing fingers to be inserted into the ring holder to enhance the stability of holding electronic devices such as mobile phones, the ring holder can also be flipped to become a support accessory, allowing electronic devices to be supported at different angles on various flat surfaces.

[0004] In existing technologies, common structures for realizing the opening and closing function of a bracket typically include a bracket base, a support component, and a rotating component (such as a pivot or hinge) connecting the two. To guide and limit the rotation trajectory and provide damping or positioning feel, a sliding groove is often provided on the bracket base. The connector or slider on the rotating component moves within the sliding groove. However, the traditional sliding groove design has some inherent defects: the trajectory of the sliding groove (especially its guide surface) is usually fixed. During the opening and closing process, the contact angle and pressure between the connector and the guide surface will change significantly with the rotation angle, resulting in uneven friction. Especially at certain critical positions (such as when it is close to fully open or closed), the friction may increase sharply, causing jamming, abnormal noise, or even requiring the user to apply excessive force to complete the operation, which seriously affects the smoothness and feel of opening and closing.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of the above, this utility model addresses the deficiencies of the existing technology, and its main objective is to provide a bracket that opens and closes smoothly. This is achieved through the structural design and coordination between the bracket base, support member, and rotating assembly. The rotating assembly includes at least a connector, on which a sliding part is provided for sliding contact with a sliding contact surface. The sliding part can drive a second guide part to switch between a first position and a second position to change the tilt angle of the sliding contact surface. Thus, in the closed state, the support angle of the sliding contact surface to the sliding part changes, increasing the normal pressure of the sliding part on the sliding contact surface and consequently increasing the friction. This makes the bracket move more smoothly when closed and maintains its position through friction after closing. In the open state, the friction is optimized, the sliding contact surface returns to a gentle or sloping shape, the normal pressure decreases, the friction is reduced, and the movement resistance is lowered, allowing the sliding part to slide smoothly along the sliding contact surface without jamming.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A bracket that opens and closes smoothly includes a bracket base and a support member. The support member can be switched between an open state and a closed state relative to the bracket base via a rotating component. The support member is in a transmission engagement with the rotating component. The bracket base is provided with a sliding groove.

[0009] The sliding groove is provided with a guide member, which includes at least a first guide part and a second guide part. The second guide part is movably connected to the first guide part, and the outer wall surface of the first guide part is connected to the second guide part to form a sliding contact surface.

[0010] The rotating assembly includes at least a connector, and the connector is provided with a sliding part for slidingly engaging with the sliding contact surface. The sliding part can drive the second guide part to switch between a first position and a second position to change the tilt angle of the sliding contact surface.

[0011] In the closed state, the support member rotates in the first direction to close, and the second guide part moves along the rotation direction of the support member to the first tilted state under the action of the sliding part.

[0012] In the open state, the support member rotates to open in the second direction opposite to the first direction, and the second guide part moves to the second tilt state along the rotation direction of the support member under the action of the sliding part.

[0013] As a preferred embodiment, the sliding groove is further provided with a clearance groove at one end near the second guide portion, the clearance groove being used to provide clearance space for the second guide portion to move.

[0014] As a preferred embodiment, a guide slope is provided on the end face of the second guide portion away from the first guide portion, so as to provide a guiding effect to the sliding portion when opening or closing.

[0015] As a preferred embodiment, the junction between the first guide portion and the second guide portion is provided with a crease to facilitate the bending of the second guide portion, so as to allow the second guide portion to move up and down normally.

[0016] As a preferred embodiment, the bottom surface of the bracket base is provided with an installation position, and a positioning protrusion is provided at the installation position. The guide is installed and positioned within the installation position. The guide further includes a positioning part and an elastic connecting part. The first guide part and the second guide part are connected to the positioning part through the elastic connecting part, and the positioning part is installed and positioned on the positioning protrusion.

[0017] As a preferred embodiment, the support base is further provided with a movable groove for providing a rotation space for the rotating component, and the sliding groove is connected to the movable groove; the rotating component also includes a spring piece, which can provide support members to rotate and open around the support base and can form a support limit on the support members in the supported state.

[0018] As a preferred embodiment, a rotating groove is also provided on the side of the sliding groove, and a rotating part is provided on the spring piece, which is rotatably disposed in the rotating groove.

[0019] As a preferred embodiment, the connector includes a first mating portion and a second mating portion, the first mating portion being connected to the support member, and the second mating portion being hinged to the spring piece via a pivot; the sliding portion extends from the side of the second mating portion near the sliding groove.

[0020] As a preferred embodiment, the support member is provided with an annular groove, a magnet is installed in the annular groove, and the inner sidewall of the bracket base is provided with fine teeth.

[0021] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly relies on the structural design and cooperation between the support base, the support member, and the rotating component. The support member can switch between an open state and a closed state relative to the support base through the rotating component. The rotating component includes at least a connecting member. The connecting member is provided with a sliding part for sliding cooperation with the sliding contact surface. The sliding part can drive the second guide part to switch between a first position and a second position to change the tilt angle of the sliding contact surface. In the closed state, the support member rotates to close in the first direction. Under the action of the sliding part, the second guide part moves along the rotation direction of the support member to the first tilt state. Thus, in the closed state, after the sliding part of the connecting member slides, the support angle of the sliding contact surface to the sliding part changes (e.g., from horizontal to uphill), which increases the normal pressure of the sliding part on the sliding contact surface (or changes the contact area). The friction increases accordingly, making the movement of the support more stable when it is closed (avoiding rapid impact). After closing, the position is maintained by friction (e.g., locking or buffering function).

[0022] Secondly, the friction is optimized when the device is open. After the guide moves down, the sliding contact surface returns to a flat or downhill shape, the normal pressure decreases, the friction decreases, and the movement resistance is reduced, so that the sliding part slides smoothly along the sliding contact surface and avoids jamming (such as by optimizing the curvature of the sliding contact surface to reduce mechanical interference during movement). This achieves dynamic balance of forces during the opening and closing of the bracket (increased resistance when closed and reduced resistance when open).

[0052] A bracket that opens and closes smoothly includes a bracket base 1 and a support member 2.

[0053] The support member 2 can be switched between an open state and a closed state relative to the bracket base 1 via the rotating component 3; the support member 2 and the rotating component 3 are in a transmission engagement.

[0054] The support base 1 is provided with a sliding groove 11; a guide member 12 is provided in the sliding groove 11, the guide member 12 includes at least a first guide part 121 and a second guide part 122, the second guide part 122 is movably connected to the first guide part 121, the first guide part 121 is connected to the outer wall surface of the second guide part 122 to form a sliding contact surface 123; the guide member 12 also has a U-shaped groove, and the guide member 12 can be a spring or a metal part.

[0055] Preferably, a guide slope 124 is provided on the end face of the second guide portion 122 away from the first guide portion 121, so as to provide a guiding effect to the sliding portion 311 when it is opened or closed.

[0056] Preferably, a crease 125 is provided at the junction of the first guide portion 121 and the second guide portion 122 to facilitate the bending of the second guide portion 122, so as to facilitate the normal up and down movement of the second guide portion 122.

[0057] Preferably, the sliding groove 11 is further provided with a clearance groove 13 at one end near the second guide portion 122, the clearance groove 13 being used to provide clearance space for the second guide portion 122 to move.

[0058] Preferably, a mounting position 14 is provided on the bottom surface of the bracket base 1, and a positioning protrusion is provided at the mounting position 14. The guide member 12 is installed and positioned in the mounting position 14. The guide member 12 further includes a positioning part 126 and an elastic connecting part 127. The first guide part 121 and the second guide part 122 are connected to the positioning part 126 through the elastic connecting part 127. The positioning part 126 is installed and positioned on the positioning protrusion.

[0059] Preferably, the support base 1 is further provided with a movable groove 15 for providing a flipping space for the rotating component 3, and the sliding groove 11 is connected to the movable groove 15;

[0060] The rotating assembly 3 includes at least a connector 31, on which a sliding part 311 is provided for slidingly engaging with the sliding contact surface 123. The sliding part 311 can drive the second guide part 122 to switch between a first position and a second position to change the tilt angle of the sliding contact surface 123.

[0061] In the closed state, the support member 2 rotates in the first direction to close, and the second guide part 122, under the action of the sliding part 311, moves along the rotation direction of the support member 2 to the first inclined state (uphill state); in this embodiment, as Figure 8 As shown, it illustrates the sliding trajectory of the sliding part 311, which slides from the first guide part 121 to the second guide part 122. During the sliding process, the sliding contact surface 123 changes.

[0062] In the open state, the support member 2 rotates open in a second direction opposite to the first direction, and the second guide part 122, under the action of the sliding part 311, moves along the rotation direction of the support member 2 to a second inclined state (downhill state). Figure 9 As shown, it illustrates the sliding trajectory of the sliding part 311, which slides from the second guide part 122 to the first guide part 121. During the sliding process, the sliding contact surface 123 changes.

[0063] When the bracket is closed, the sliding part 311 of the connector 31 moves to one end of the sliding contact surface, causing the second guide part 122 to move upward and change the direction of the sliding contact surface, thereby increasing the friction at the contact point (between the sliding part 311 and the guide part 12).

[0064] In the closed state, the support member 2 rotates to close in the first direction. Under the action of the sliding part 311, the second guide part 122 moves along the rotation direction of the support member 2 to a first inclined state (meaning the sliding part 311 slides from the first guide part 121 along the second guide part 122). Utilizing the movable design of the second guide part 122, when the sliding part 311 slides from the first guide part 121 to the second guide part 122, the force applied by the support member 2 will cause the second guide part 122 to move towards the clearance groove 13. At this time, the horizontal state of the sliding contact surface changes to an inclined state (meaning uphill), thereby increasing the normal pressure of the sliding part 311 on the sliding contact surface 123, and consequently increasing the friction.

[0065] In the open state, the support member 2 rotates open in the second direction opposite to the first direction. Under the action of the sliding part 311, the second guide part 122 moves along the rotation direction of the support member 2 to the first inclined state (that is, the sliding part 311 slides from the second guide part 122 along the first guide part 121). Utilizing the movable design of the second guide part 122, when the sliding part 311 slides along the guide slope 124 onto the second guide part 122, the sliding contact surface 123 returns to a gentle or downhill shape, reducing the positive pressure, friction, and movement resistance, allowing the sliding part 311 to slide smoothly along the sliding contact surface 123 and avoiding jamming.

[0066] When the bracket is opened, the sliding part 311 of the connector 31 moves to the other end of the guide 12, causing the second guide 122 to move downward and change the direction of the sliding contact surface. The change of direction design of the sliding contact surface (through the displacement of the second guide 122) eliminates the dead point of motion (such as right-angle turns or sudden slopes), so that the sliding part 311 always moves along the continuous and smooth sliding contact surface during the opening and closing process (avoiding rigid collisions or jamming).

[0067] Preferably, the connector 31 includes a first docking portion 312 and a second docking portion 313. The first docking portion 312 is connected to the support member 2, and the second docking portion 313 is hinged to the spring piece 32 via a pivot 33. The sliding portion 311 extends from the side of the second docking portion 313 near the sliding groove 11.

[0068] Preferably, the rotating component 3 further includes a spring piece 32, which can provide support member 2 to rotate and open around the bracket base 1 and can form a support limit on support member 2 in the supported state.

[0069] Preferably, a rotating groove 16 is also provided on the side of the sliding groove 11, and a rotating part 321 is provided on the spring piece 32, which is rotatably disposed in the rotating groove 16.

[0070] Preferably, the support member 2 is provided with an annular groove, the annular groove is equipped with a magnet, and the inner sidewall of the bracket base 1 is provided with fine teeth 17.

[0071] The key design feature of this invention lies in the structural design and coordination between the support base, the support member, and the rotating assembly. The support member can switch between an open and closed state relative to the support base via the rotating assembly. The rotating assembly includes at least a connector, which has a sliding part for sliding contact with a sliding contact surface. The sliding part can drive a second guide part to switch between a first position and a second position to change the tilt angle of the sliding contact surface. In the closed state, the support member rotates in the first direction to close. Under the action of the sliding part, the second guide part moves along the rotation direction of the support member to the first tilt state. Thus, in the closed state, after the sliding part of the connector slides, the support angle of the sliding contact surface to the sliding part changes (e.g., from horizontal to uphill), increasing the normal pressure of the sliding part on the sliding contact surface (or changing the contact area), and increasing the frictional force. This makes the movement of the support more stable when it closes (avoiding rapid impact) and maintains its position through friction after closing (e.g., locking or buffering function).

[0072] Secondly, the friction is optimized when the device is open. After the guide moves down, the sliding contact surface returns to a flat or downhill shape, the normal pressure decreases, the friction decreases, and the movement resistance is reduced, so that the sliding part slides smoothly along the sliding contact surface and avoids jamming (such as by optimizing the curvature of the sliding contact surface to reduce mechanical interference during movement). This achieves dynamic balance of forces during the opening and closing of the bracket (increased resistance when closed and reduced resistance when open).

[0073] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
