Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, and more specifically, to a bracket. Background Technology

[0002] In modern life, tablets and smartphones have become indispensable parts of our daily communication, work, and entertainment. With the increasing variety of electronic devices on the market, different brands and models come in diverse sizes, including significant differences in length and width. This necessitates that stands and mounting devices not only provide stable support for the devices but also possess good adaptability, allowing for quick switching between different devices to meet the diverse needs of a wide range of users.

[0003] However, most mounting brackets currently on the market have certain limitations in their design. Although these brackets can be adjusted manually or mechanically to accommodate devices of different sizes, in practice, users often need to perform relatively complicated adjustment steps. For example, patent JP3236890U discloses an automatic clamping phone holder. Although the phone holder can fit different sized phones, users need to loosen the fixing screws, move the position of the clamps according to the width of the phone, and retighten the fixing screws. These adjustment operations are relatively complicated, resulting in a poor user experience. Utility Model Content

[0004] The main purpose of this utility model is to provide a bracket that can solve the problem that although the existing mounting brackets can adapt to equipment of different sizes, the adjustment operation is relatively complicated, resulting in a poor user experience.

[0005] To achieve the above objectives, this utility model provides a support, comprising: a housing; a first clamping part, including a first clamp and a second clamp disposed opposite to each other along a first direction and capable of synchronously moving towards or away from each other relative to the housing; a second clamping part, including a third clamp and a fourth clamp disposed opposite to each other along a second direction and capable of synchronously moving towards or away from each other relative to the housing, the first direction and the second direction being arranged at an angle, the first clamp, the second clamp, the third clamp, and the fourth clamp together forming a clamping space; and a transmission part, mounted on the housing, having a first transmission state and a second transmission state, and capable of automatically switching between the first transmission state and the second transmission state. When the transmission part is in the first transmission state, the first clamping part is driven and engaged with the second clamping part through the transmission part, and the first clamping part and the second clamping part are linked. When the transmission part is in the second transmission state, the movement of the first clamping part and the movement of the second clamping part are independent of each other.

[0006] Furthermore, the transmission unit includes a first gear and a second gear rotatably disposed within the housing. The ends of the first and second grippers facing each other are both engaged with the first gear, and the ends of the third and fourth grippers facing each other are both engaged with the second gear. The transmission unit also includes a first ratchet and a second ratchet, both of which are capable of moving toward or away from each other. The first ratchet is disposed on the first gear and forms an anti-rotation engagement with the first gear, and the second ratchet is disposed on the second gear and forms an anti-rotation engagement with the second gear. When the transmission unit is in the first transmission state, the first ratchet and the second ratchet are engaged, and when the transmission unit is in the second transmission state, the first ratchet and the second ratchet are disengaged.

[0007] Furthermore, the transmission unit also includes a first elastic member and a second elastic member. The first elastic member elastically abuts between the housing and the first ratchet, and the first elastic member can provide a force for the first ratchet to move away from the second ratchet. The second elastic member elastically abuts between the housing and the second ratchet, and the second elastic member can provide a force for the second ratchet to move closer to the first ratchet.

[0008] Furthermore, the ratchet teeth of the first ratchet include a first inclined surface, and the ratchet teeth of the second ratchet include a second inclined surface. When the first clamping part and the second clamping part move synchronously, the first inclined surface and the second inclined surface press against each other. When the first clamping part is in place and the second clamping part continues to move, under the pressing force of the first inclined surface on the second inclined surface, the second ratchet moves away from the first ratchet until it disengages from the first ratchet.

[0009] Furthermore, the housing includes a separate upper housing and a lower housing, and the bracket also includes a pressing member that is movably disposed relative to the upper housing along a third direction. The top of the pressing member protrudes outside the housing, and along the third direction, the bottom of the pressing member forms a stop engagement with the inner wall of the upper housing. The first ratchet is located at the bottom of the pressing member and on the moving path of the pressing member. The pressing member can move along the third direction under the action of external force and drive the first ratchet to move towards the second ratchet until the first ratchet engages with the second ratchet.

[0010] Furthermore, the bottom surface of the lower housing is provided with a support ring extending in a third direction. The second ratchet and the second elastic element are sequentially sleeved on the outer periphery of the support ring from top to bottom. The first ratchet has a first annular protrusion and a second annular protrusion sequentially arranged from the inside to the outside on the side facing the second ratchet. The ratchet teeth of the first ratchet are arranged on the second annular protrusion. An annular groove is formed between the first annular protrusion and the second annular protrusion. The annular groove is correspondingly arranged with the support ring, and the top of the support ring is engaged in the annular groove. Alternatively, when the first ratchet moves away from the second ratchet under the force of the first elastic element, the first ratchet can drive the pressing element to move in a third direction until the pressing element is reset.

[0011] Furthermore, the bracket also includes a locking assembly mounted on the housing. The locking assembly includes a locking member having a locked position and an unlocked position. The locking member is movably disposed relative to the housing in a second direction to switch between the locked position and the unlocked position. When the locking member is in the locked position, one end of the locking member can engage with the first clamping part to restrict the first clamping part from opening outward.

[0012] Furthermore, along the second direction, at least one side of the first gripper and / or the second gripper is provided with a plurality of first ratchet teeth arranged along the first direction, and the locking member is provided with a second ratchet tooth at one end facing the first ratchet tooth. When the locking member is in the locked position, the first ratchet tooth can engage with the second ratchet tooth and can form a stop engagement with the second ratchet tooth in the opening direction of the first clamping part. When the first gripper and the second gripper move toward each other, the first ratchet tooth can squeeze the second ratchet tooth to make the locking member move away from the first ratchet tooth along the second direction. When the locking member is in the unlocked position, the second ratchet tooth disengages from the first ratchet tooth.

[0013] Furthermore, the locking assembly also includes an adjustment assembly, the locking member having a guide ramp located on the movement path of the adjustment assembly, the guide ramp extending obliquely from the side where the first ratchet is located along a second direction away from the first ratchet, the adjustment assembly being movably disposed relative to the housing along a first direction and capable of engaging with the guide ramp to switch the locking member between a locked position and an unlocked position.

[0014] Furthermore, the housing is provided with a baffle corresponding to the locking member, and the locking assembly also includes a third elastic member. One end of the third elastic member is connected to the end of the locking member away from the first ratchet, and the other end of the third elastic member abuts against the baffle. The third elastic member can provide the locking member with a force to return to the locked position.

[0015] By applying the technical solution of this utility model, the first and second grippers can be synchronously moved towards or away from each other along a first direction relative to each other on the housing, and the third and fourth grippers can be synchronously moved towards or away from each other along a second direction relative to each other on the housing. This allows the bracket of this application to adapt to electronic devices of different sizes, improving its applicability. Simultaneously, since the first and second gripping parts are driven together by a transmission part, when the transmission part is in the first transmission state, the first gripping part (the first and second grippers) and the second gripping part (the third and fourth grippers) can move in tandem. At this time, when the user operates one gripping part, the other gripping part can respond synchronously, simplifying the adjustment operation and significantly improving the user experience.

[0030] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] See also Figures 1 to 11 As shown, this utility model provides a bracket, which includes: a housing 10; a first clamping part 20, including a first clamping jaw 21 and a second clamping jaw 22 disposed opposite to each other in a first direction and capable of synchronously moving towards or away from each other relative to the housing 10; and a second clamping part 30, including a third clamping jaw 31 and a fourth clamping jaw 32 disposed opposite to each other in a second direction and capable of synchronously moving towards or away from each other relative to the housing 10. The first direction and the second direction are arranged at an angle. The first clamping jaw 21, the second clamping jaw 22, and the third clamping jaw 32 are... The claw 31 and the fourth claw 32 together form a clamping space; the transmission part 40 is installed on the housing 10. The transmission part 40 has a first transmission state and a second transmission state, and the transmission part 40 can automatically switch between the first transmission state and the second transmission state. When the transmission part 40 is in the first transmission state, the first clamping part 20 is driven and engaged with the second clamping part 30 through the transmission part 40, and the first clamping part 20 and the second clamping part 30 are linked. When the transmission part 40 is in the second transmission state, the movement of the first clamping part 20 and the movement of the second clamping part 30 are independent of each other.

[0032] In this embodiment, the first gripper 21, the second gripper 22, the third gripper 31, and the fourth gripper 32 together form a clamping space. An electronic device (e.g., a mobile phone, tablet computer, etc.) is located within this clamping space and is clamped and fixed by the first gripper 21, the second gripper 22, the third gripper 31, and the fourth gripper 32. Since the first gripper 21 and the second gripper 22 can move synchronously towards or away from each other along a first direction relative to each other on the housing 10, and the third gripper 31 and the fourth gripper 32 can move synchronously towards or away from each other along a second direction relative to each other on the housing 10, the bracket of this application can adapt to electronic devices with different aspect ratios, thus improving its applicability. Meanwhile, since the first clamping part 20 and the second clamping part 30 are driven and cooperated through the transmission part 40, when the transmission part 40 is in the first transmission state, the first clamping part 20 (first gripper 21 and second gripper 22) and the second clamping part 30 (third gripper 31 and fourth gripper 32) can be linked together. At this time, when the user operates one of the clamping parts, the other clamping part can respond synchronously. For example, when the user pushes the first gripper 21, the first gripper 21 and the second gripper 22 of the first clamping part 20 move synchronously towards each other until they clamp the electronic device. At this time, the third gripper 31 and the fourth gripper 32 in the second clamping part 30 also move synchronously towards each other until they clamp the electronic device. This simplifies the adjustment operation and greatly improves the user experience. When the transmission unit 40 is in the second transmission state, the movement of the first clamping part 20 and the second clamping part 30 is independent of each other. That is, the movement of the first clamp 21 and the second clamp 22 will not affect the movement of the third clamp 31 and the fourth clamp 32, and pushing and pulling the first clamp 21 will not affect the movement of the third clamp 31 and the fourth clamp 32.

[0033] The transmission unit 40 can automatically switch between the first transmission state and the second transmission state, so that the user can realize the linkage or independent operation of the first clamping unit 20 and the second clamping unit 30 without manually adjusting the transmission state of the transmission unit 40 during use, which further simplifies the adjustment operation and improves the ease of use.

[0034] In one embodiment, the first direction is perpendicular to the second direction. The bracket of this application can clamp the electronic device in one step. The electronic device can be clamped in two mutually perpendicular directions, ensuring that it can be stably clamped and positioned regardless of the aspect ratio of the electronic device. The operation is simple and convenient. At the same time, the overall appearance of the electronic device is centered and symmetrical after installation.

[0035] See also Figures 1 to 11As shown, in one embodiment of the present invention, the transmission part 40 includes a first gear 41 and a second gear 42 rotatably disposed within the housing 10. The ends of the first pawl 21 and the second pawl 22 facing each other are engaged with the first gear 41. The ends of the third pawl 31 and the fourth pawl 32 facing each other are engaged with the second gear 42. The transmission part 40 also includes a first ratchet 43 and a second ratchet 44, both of which are capable of moving towards or away from each other. The first ratchet 43 is disposed on the first gear 41 and forms an anti-rotation engagement with the first gear 41. The second ratchet 44 is disposed on the second gear 42 and forms an anti-rotation engagement with the second gear 42. When the transmission part 40 is in the first transmission state, the first ratchet 43 and the second ratchet 44 are engaged. When the transmission part 40 is in the second transmission state, the first ratchet 43 and the second ratchet 44 are disengaged.

[0036] In this embodiment, the ends of the first gripper 21 and the second gripper 22 facing each other are both engaged with the first gear 41. The first gear 41 enables synchronous movement of the first gripper 21 and the second gripper 22. For example, pushing the first gripper 21 causes it to move along a first direction towards the second gripper 22, at which point the second gripper 22 also moves synchronously along the first direction towards the first gripper 21. Similarly, the ends of the third gripper 31 and the fourth gripper 32 facing each other are both engaged with the second gear 42. The second gear 42 enables synchronous movement of the third gripper 31 and the fourth gripper 32. For example, pushing the third gripper 31 causes it to move along a second direction towards the fourth gripper 32, at which point the fourth gripper 32 also moves synchronously along the second direction towards the third gripper 31.

[0037] The first ratchet 43 is mounted on the first gear 41 and does not rotate relative to the first gear 41. The first ratchet 43 rotates synchronously with the first gear 41. The second ratchet 44 is mounted on the second gear 42 and does not rotate relative to the second gear 42. The second ratchet 44 rotates synchronously with the second gear 42. When the transmission part 40 is in the first transmission state, the first ratchet 43 and the second ratchet 44 are engaged. At this time, the first gear 41 and the second gear 42 rotate synchronously and in the same direction, thereby enabling the first clamping part 20 and the second clamping part 30 to move synchronously. When the transmission part 40 is in the second transmission state, the first ratchet 43 and the second ratchet 44 are disengaged. At this time, the first ratchet 43 and the second ratchet 44 are not engaged, and there is no transmission relationship between the first gear 41 and the second gear 42. The rotation of the first gear 41 and the second gear 42 is independent of each other.

[0038] It should be noted that when the first jaw 21 and the second jaw 22 retract synchronously, the rotation direction of the first gear 41 is the same as the rotation direction of the second gear 42 when the third jaw 31 and the fourth jaw 32 retract synchronously. That is, when the first jaw 21 and the second jaw 22 retract synchronously, the first gear 41 rotates counterclockwise, and therefore, when the third jaw 31 and the fourth jaw 32 retract synchronously, the second gear 42 also rotates counterclockwise. Alternatively, when the first jaw 21 and the second jaw 22 retract synchronously, the first gear 41 rotates clockwise, and therefore, when the third jaw 31 and the fourth jaw 32 retract synchronously, the second gear 42 also rotates clockwise. Similarly, when the first jaw 21 and the second jaw 22 open synchronously, the rotation direction of the first gear 41 is the same as the rotation direction of the second gear 42 when the third jaw 31 and the fourth jaw 32 open synchronously. This will not be elaborated further here.

[0039] See also Figures 1 to 11 As shown, in one embodiment of the present invention, the transmission part 40 further includes a first elastic member 45 and a second elastic member 46. The first elastic member 45 elastically abuts between the housing 10 and the first ratchet 43, and the first elastic member 45 can provide a force for the first ratchet 43 to move away from the second ratchet 44. The second elastic member 46 elastically abuts between the housing 10 and the second ratchet 44, and the second elastic member 46 can provide a force for the second ratchet 44 to move closer to the first ratchet 43.

[0040] In this embodiment, initially, the first ratchet 43 and the second ratchet 44 are not engaged. When the electronic device is placed in the clamping space, the first elastic member 45 is compressed. After the electronic device is removed from the bracket, under the elastic force of the first elastic member 45, the first ratchet 43 can move away from the second ratchet 44, returning to its initial position. At this time, the first ratchet 43 and the second ratchet 44 are not engaged, and the movement of the first clamping part 20 and the movement of the second clamping part 30 are independent of each other. The third gripper 31 and the fourth gripper 32 can continue to extend outward to their maximum extension position. Under the elastic restoring force of the second elastic member 46, the second ratchet 44 can move towards the first ratchet 43, engaging the first ratchet 43 and the second ratchet 44, thereby achieving the linkage between the first clamping part 20 and the second clamping part 30.

[0041] See also Figures 1 to 11As shown, in one embodiment of the present invention, the ratchet teeth of the first ratchet 43 include a first inclined surface 431, and the ratchet teeth of the second ratchet 44 include a second inclined surface 441. When the first clamping part 20 and the second clamping part 30 move synchronously, the first inclined surface 431 and the second inclined surface 441 press against each other. When the first clamping part 20 clamps in place and the second clamping part 30 continues to move, under the pressing force of the first inclined surface 431 on the second inclined surface 441, the second ratchet 44 moves away from the first ratchet 43 until it disengages from the first ratchet 43.

[0042] In this embodiment, when the first clamping part 20 and the second clamping part 30 need to move synchronously, the mutual compression of the first inclined surface 431 and the second inclined surface 441 ensures that the first ratchet 43 and the second ratchet 44 remain engaged, so that the first gear 41 and the second gear 42 can rotate synchronously, thereby realizing the synchronous retraction or extension of the first gripper 21, the second gripper 22, the third gripper 31 and the fourth gripper 32.

[0043] When the first gripper 21 and the second gripper 22 of the first gripping part 20 have been gripped in place, and the second gripping part 30 needs to continue moving until it is also gripped in place, under the squeezing force of the first inclined surface 431 on the second inclined surface 441, the second ratchet 44 can move away from the first ratchet 43 until the first ratchet 43 and the second ratchet 44 disengage. At this time, the movement between the first gripping part 20 and the second gripping part 30 is independent of each other, allowing the second gripping part 30 to continue to retract until the second gripping part 30 is also gripped in place.

[0044] It should be noted that the first ratchet 43 of this application can move relative to the first gear 41 in a direction that approaches or moves away from the second ratchet 44, but cannot rotate relative to the first gear 41. Similarly, the second ratchet 44 of this application can move relative to the second gear 42 in a direction that approaches or moves away from the first ratchet 43, but cannot rotate relative to the second gear 42.

[0045] See also Figures 1 to 11 As shown, in one embodiment of the present invention, the housing 10 includes a separate upper housing 11 and a lower housing 12. The bracket also includes a pressing member 50 that is movably disposed relative to the upper housing 11 along a third direction. The top of the pressing member 50 protrudes outside the housing 10. Along the third direction, the bottom of the pressing member 50 forms a stop engagement with the inner wall of the upper housing 11. The first ratchet 43 is located at the bottom of the pressing member 50 and on the moving path of the pressing member 50. The pressing member 50 can move along the third direction under the action of external force and drive the first ratchet 43 to move towards the second ratchet 44 until the first ratchet 43 engages with the second ratchet 44.

[0046] In this embodiment, third-party refers to Figure 9The vertical direction of the press member 50. Before the electronic device is placed, the top of the press member 50 protrudes from the housing 10, that is, the top of the press member 50 is outside the housing 10, and the bottom of the press member 50 and the inner wall of the upper housing 11 can form a stop engagement in the third direction to prevent the press member 50 from falling out of the housing 10. The first ratchet 43 is supported below the press member 50, and the bottom surface of the press member 50 abuts against the top surface of the first ratchet 43. When the electronic device is placed in the clamping space, the electronic device will press down the press member 50, and the press member 50 will press down the first ratchet 43, so that the first ratchet 43 moves relative to the first gear 41 towards the second ratchet 44 until it meshes with the second ratchet 44. At this time, the first clamping part 20 and the second clamping part 30 are linked together, which can realize the synchronous extension and retraction of the first gripper 21, the second gripper 22, the third gripper 31 and the fourth gripper 32.

[0047] When the electronic device is placed in the clamping space, the electronic device presses down on the pressing member 50. The pressing member 50 pushes the first gear 41 to move closer to the second ratchet 44 until it engages with the second ratchet 44. When the third gripper 31 or the fourth gripper 32 retracts, the first gripper 21 and the second gripper 22 also retract synchronously. When the first gripper 21 and the second gripper 22 clamp the electronic device, if the third gripper 31 and the fourth gripper 32 fail to clamp the electronic device, the third gripper 31 or the fourth gripper 32 continues to be pushed to retract. The second gear 42 drives the second ratchet 44 to continue rotating. At this time, the first gear 41 and the first ratchet 43 cannot rotate. With the cooperation of the first inclined surface 431 and the second inclined surface 441, the second ratchet 44 moves away from the first ratchet 43, releasing the engagement between the second ratchet 44 and the first ratchet 43. At this time, the third gripper 31 and the fourth gripper 32 can retract inwards independently to adapt to electronic devices with fixed aspect ratios.

[0048] See also Figures 1 to 11 As shown, in one embodiment of the present invention, when the first ratchet 43 moves away from the second ratchet 44 under the force of the first elastic member 45, the first ratchet 43 can drive the pressing member 50 to move in a third direction until the pressing member 50 is reset.

[0049] In this embodiment, when the first ratchet 43 moves away from the second ratchet 44 under the force of the first elastic member 45, the first ratchet 43 can push against the pressing member 50, causing the pressing member 50 to move away from the second ratchet 44 in a third direction until the pressing member 50 moves to the initial position, that is, the top of the pressing member 50 protrudes from the housing 10 and forms a stop engagement with the inner wall of the upper housing 11 in a third direction.

[0050] See also Figures 1 to 11As shown, in one embodiment of the present invention, a support ring 121 extending in a third direction is provided on the bottom surface of the lower housing 12. The second ratchet 44 and the second elastic member 46 are sequentially sleeved on the outer periphery of the support ring 121 from top to bottom. The first ratchet 43 is provided with a first annular protrusion 434 and a second annular protrusion 432 sequentially from the inside to the outside on the side facing the second ratchet 44. The ratchet teeth of the first ratchet 43 are provided on the second annular protrusion 432. An annular groove 433 is formed between the first annular protrusion 434 and the second annular protrusion 432. The annular groove 433 is correspondingly provided with the support ring 121, and the top of the support ring 121 is inserted into the annular groove 433.

[0051] In this embodiment, the support ring 121 has an inner cavity. One end of the first elastic member 45 is supported at the bottom of the first ratchet 43, and the other end of the first elastic member 45 is located in the inner cavity of the support ring 121 and abuts against the bottom wall of the inner cavity of the support ring 121. The second elastic member 46 is sleeved on the outer periphery of the support ring 121, and the second ratchet 44 is sleeved on the outer periphery of the support ring 121 and can rotate relative to the support ring 121. The second ratchet 44 is located above the second elastic member 46. The bottom of the first annular protrusion 434 is inserted into the inner cavity of the support ring 121, and the top of the support ring 121 is engaged in the annular groove 433. When the first ratchet 43 moves in a third direction toward the second ratchet 44, the top of the support ring 121 enters the annular groove 433 further. The configuration of the support ring 121 provides positioning for the installation of the second ratchet 44 and the second elastic member 46, and also provides guidance for the second ratchet 44.

[0052] The first annular protrusion 434 and the second annular protrusion 432 form a guide structure on the first ratchet 43. The annular groove 433 formed between them matches the support ring 121, so that when the first ratchet 43 moves towards the second ratchet 44, the support ring 121 can accurately guide its movement trajectory, preventing the first ratchet 43 from shifting laterally during movement and ensuring accurate engagement and disengagement between the ratchets. By setting the support ring 121 inside the lower housing 12 and setting the first annular protrusion 434 and the second annular protrusion 432 on the first ratchet 43, efficient component configuration within a limited space is achieved, saving internal space and maintaining external aesthetics and compactness.

[0053] See also Figures 1 to 11As shown, in one embodiment of this utility model, the bracket further includes a column 80, a cover 100, and a connecting bolt 90. The first end of the connecting bolt 90 is located in the inner cavity of the support ring 121 and is threadedly engaged with the bottom wall of the inner cavity of the support ring 121. The second end of the connecting bolt 90 extends out of the housing 10 and is threadedly connected to the column 80, thereby realizing the connection between the housing 10 and the column 80. The cover 100 is installed in the inner cavity of the support ring 121 and covers the first end of the connecting bolt 90. The bottom of the first elastic member 45 abuts against the cover 100.

[0054] See also Figures 1 to 11 As shown, in one embodiment of the present invention, the bracket further includes a locking component 60 mounted on the housing 10. The locking component 60 includes a locking member 61 having a locked position and an unlocked position. The locking member 61 is movably disposed relative to the housing 10 in a second direction so that the locking member 61 can switch between the locked position and the unlocked position. When the locking member 61 is in the locked position, one end of the locking member 61 can cooperate with the first clamping part 20 to restrict the first clamping part 20 from opening outward.

[0055] In this embodiment, when the locking member 61 is in the locked position, it cooperates with the first clamping part 20 to effectively restrict the outward opening of the first clamping part 20, thereby preventing unauthorized removal of electronic devices, increasing the difficulty of theft of electronic devices, improving the anti-theft effect, and ensuring property security.

[0056] See also Figures 1 to 11 As shown, in one embodiment of the present invention, at least one side of the first gripper 21 and / or the second gripper 22 is provided with a plurality of first ratchet teeth 23 arranged in the first direction along the second direction. The locking member 61 is provided with a second ratchet tooth 611 at one end facing the first ratchet tooth 23. When the locking member 61 is in the locked position, the first ratchet tooth 23 can engage with the second ratchet tooth 611 and can form a stop engagement with the second ratchet tooth 611 in the opening direction of the first clamping part 20. When the first gripper 21 and the second gripper 22 move toward each other, the first ratchet tooth 23 can squeeze the second ratchet tooth 611 to make the locking member 61 move away from the first ratchet tooth 23 along the second direction. When the locking member 61 is in the unlocked position, the second ratchet tooth 611 disengages from the first ratchet tooth 23.

[0057] In this embodiment, the first ratchet 23 on the gripper engages with the second ratchet 611 of the locking member 61 in the locked position, effectively preventing the first gripper 21 and the second gripper 22 from opening outward, thereby firmly securing the electronic device and significantly enhancing the reliability of the anti-theft function and the security of the device. At this time, the first gripper 21 and the second gripper 22 cannot move away from each other along the first direction, but they can move closer to each other along the first direction. That is, when the locking member 61 is in the locked position, the first gripper 21 and the second gripper 22 of the first clamping part 20 can only retract inward and cannot extend outward.

[0058] When the locking member 61 is in the unlocked position, the second ratchet 611 disengages from the first ratchet 23. At this time, the first gripper 21 and the second gripper 22 can extend and retract normally to facilitate the installation of electronic devices. When the locking member 61 is in the locked position, the first ratchet 23 and the second ratchet 611 engage with a stop to form a stable locked state. However, when the first gripper 21 and the second gripper 22 need to move closer to each other (i.e., clamp the tablet computer), the first ratchet 23 can compress the second ratchet 611, causing the locking member 61 to move in the second direction to the unlocked position. This design ensures an unlocking mechanism when clamping the tablet computer, making the transition between locking and unlocking smooth and quick, thus improving operational efficiency.

[0059] See also Figures 1 to 11 As shown, in one embodiment of the present invention, the locking component 60 further includes an adjusting component 62. The locking member 61 has a guide ramp 614 located on the moving path of the adjusting component 62. The guide ramp 614 extends obliquely from the side where the first ratchet 23 is located along the second direction in a direction away from the first ratchet 23. The adjusting component 62 is movably disposed relative to the housing 10 along the first direction and can abut against the guide ramp 614 to switch the locking member 61 between a locked position and an unlocked position.

[0060] In this embodiment, the cooperation between the adjustment component 62 and the guide ramp 614 enables the locking member 61 to switch between the locked and unlocked positions. That is, by simply moving the adjustment component 62, the locking member 61 can be quickly unlocked and locked without complicated manual adjustments or multiple steps, which improves the user's ease of operation and experience.

[0061] See also Figures 1 to 11 As shown, in one embodiment of the present invention, the housing 10 is provided with a baffle 70 corresponding to the locking member 61. The locking component 60 also includes a third elastic member 63. One end of the third elastic member 63 is connected to the end of the locking member 61 away from the first ratchet 23, and the other end of the third elastic member 63 abuts against the baffle 70. The third elastic member 63 can provide the locking member 61 with a force to return to the locked position.

[0062] In this embodiment, when the adjusting component 62 moves along the first direction toward the locking member 61, the third elastic member 63 is compressed, and the adjusting component 62 can abut against the guide slope 614 and push the locking member 61 to move along the second direction away from the first ratchet 23 until the first ratchet 23 and the second ratchet 611 disengage, so that the two are not engaged, thereby enabling the locking member 61 to switch from the locked position to the unlocked position.

[0063] When the adjusting component 62 moves away from the locking member 61 along the first direction, under the elastic restoring force of the third elastic member 63, the locking member 61 can move towards the first ratchet 23 along the second direction until the second ratchet 611 engages with the first ratchet 23, thereby enabling the locking member 61 to switch from the unlocked position to the locked position.

[0064] See also Figures 1 to 11 As shown, in one embodiment of the present invention, the adjusting component 62 includes a fixing block 621 and an adjusting member 622. The fixing block 621 is fixedly installed on the lower housing 12. The fixing block 621 is provided with a threaded hole. The adjusting member 622 passes through the threaded hole and is threadedly engaged with the fixing block 621. The adjusting member 622 is provided with a spherical protrusion 623. When the adjusting member 622 moves relative to the fixing block 621 in a first direction toward the locking member 61, the spherical protrusion 623 can abut against the guide inclined surface 614 and push the locking member 61 in a second direction away from the first ratchet 23 until the first ratchet 23 disengages from the second ratchet 611, so that the two are not engaged, thereby enabling the locking member 61 to switch from the locked position to the unlocked position.

[0065] When the adjusting member 622 moves away from the locking member 61 in the first direction relative to the fixed block 621, under the elastic restoring force of the third elastic member 63, the locking member 61 can move in the second direction towards the first ratchet 23 until the second ratchet 611 engages with the first ratchet 23, thereby enabling the locking member 61 to switch from the unlocked position to the locked position.

[0066] by Figure 6 From the perspective shown, assuming that the second gripper 22 is provided with multiple first ratchet teeth 23, when the locking member 61 is in the locked position, the adjusting member 622 is at the bottom and the locking member 61 is at the rightmost position. The second ratchet tooth 611 of the locking member 61 engages with the first ratchet tooth 23, thereby realizing the anti-theft function that the second gripper 22 cannot extend.

[0067] In one embodiment, the first elastic element 45, the second elastic element 46, and the third elastic element 63 are all springs. The adjusting element 622 is a screw or bolt.

[0068] See also Figures 1 to 11As shown, in one embodiment of the present invention, the bracket further includes two fourth elastic elements 200. Along the second direction, a mounting post 122 is provided at each of the opposite ends of the lower housing 12. A first bolt 311 is provided at the end of the third gripper 31 facing the fourth gripper 32, and a second bolt 321 is provided at the end of the fourth gripper 32 facing the third gripper 31. One end of one of the fourth elastic elements 200 is sleeved on the mounting post 122 on its side, and the other end of the fourth elastic element 200 is sleeved on the first bolt 311. One end of the other fourth elastic element 200 is sleeved on the mounting post 122 on its side, and the other end of the fourth elastic element 200 is sleeved on the second bolt 321.

[0069] It should be noted that the second elastic element 46 ensures that the first gripper 21, the second gripper 22, the third gripper 31, and the fourth gripper 32 can move synchronously when the third gripper 31 and the fourth gripper 32 are not subjected to the retraction thrust. That is, after the first gripper 21 and the second gripper 22 are in place, the third gripper 31 or the fourth gripper 32 is pushed back. Under the squeezing force of the first inclined surface 431 on the second inclined surface 441, the second ratchet 44 can move away from the first ratchet 43 until the first ratchet 43 and the second ratchet 44 disengage. At this time, the third gripper 31 and the fourth gripper 32 can continue to retract inward until they are in place.

[0070] After the third gripper 31 and the fourth gripper 32 are in position, under the elastic restoring force of the second elastic member 46, the second ratchet 44 can move closer to the first ratchet 43, causing the first ratchet 43 and the second ratchet 44 to re-engage. The first gripping part 20 and the second gripping part 30 are linked again. When the electronic device needs to be removed, the locking member is first placed in the unlocked position. At this time, the third gripper 31 and the fourth gripper 32 are pulled outward automatically by the corresponding fourth elastic member 200. Since the first gripping part 20 and the second gripping part 30 are linked at this time, Therefore, the first, second, third, and fourth grippers extend synchronously. When the first and second grippers extend to their maximum extension positions, the electronic device is removed. At this time, under the elastic force of the first elastic member 45, the first ratchet 43 moves away from the second ratchet 44, causing the first ratchet 43 to separate from the second ratchet 44. At this time, the movement of the first clamping part 20 and the movement of the second clamping part 30 are independent of each other. The third gripper 31 and the fourth gripper 32 can continue to extend outward until the third gripper 31 and the fourth gripper 32 reach their maximum extension positions.

[0071] In one embodiment, the fourth elastic element 200 is a tension spring.

[0072] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: the first and second grippers can be synchronously moved towards or away from each other along a first direction relative to each other on the housing; the third and fourth grippers can be synchronously moved towards or away from each other along a second direction relative to each other on the housing. This allows the bracket of this application to adapt to electronic devices of different sizes, resulting in better applicability. Simultaneously, since the first and second gripping parts are driven together by a transmission part, when the transmission part is in the first transmission state, the first gripping part (the first and second grippers) and the second gripping part (the third and fourth grippers) can move in tandem. At this time, when the user operates one gripping part, the other gripping part can respond synchronously, simplifying the adjustment operation and significantly improving the user experience.
