Based on ergonomics and human-machine interaction principles, it provides a better user experience for drivers. However, phone stands require adjusting the clamping width according to the phone's size. Unfortunately, existing phone stands often cause damage to the phone by applying excessive force when tightening the knob during adjustment. Utility Model Content

[0014] The technical solution provided in this application embodiment may include the following beneficial effects: The present utility model provides a knob clamping bracket, including a first clamping component and a second clamping component that move relative to each other, a connecting component and a rotating component. The connecting component moves relative to the first clamping component. Both ends of the connecting component are connected to the rotating component and the first clamping component, respectively. The connecting component is provided with a storage groove. The rotating component is provided with an elastic component. The elastic component is elastically engaged with the storage groove. As the rotating component continues to rotate, the connecting component moves relative to the first clamping assembly, which in turn causes the first and second clamping assemblies to move relative to each other. The first and second clamping assemblies can approach and clamp electronic devices such as mobile phones. The connecting component has a storage groove, and the rotating component has an elastic element that elastically engages with the storage groove. The rotating component can drive the connecting component to rotate. When the first and second clamping assemblies clamp the electronic device into place, the torque of the connecting component exceeds the deformation force of the elastic element. The elastic element rotates on the storage groove of the connecting component, and the rotating component begins to spin freely, unable to drive the connecting component to continue moving. Consequently, it cannot drive the first and second clamping assemblies to move. This overload protection design avoids excessive clamping force and damage to electronic devices such as mobile phones.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0026] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0027] Please see Figure 1 and Figure 2 This utility model provides a knob clamping bracket 10, including a first clamping component 20 and a second clamping component 30 that move relative to each other, a connecting member 11 and a rotating member 12. The connecting member 11 moves relative to the first clamping component 20, and its two ends are respectively connected to the rotating member 12 and the first clamping component 20. The connecting member 11 is provided with a storage groove 13, and the rotating member 12 is provided with an elastic member 14, which elastically engages with the storage groove 13.

[0028] As the rotating component 12 continues to rotate, the connecting component 11 moves relative to the first clamping assembly 20, which in turn causes the first clamping assembly 20 and the second clamping assembly 30 to move relative to each other. The first clamping assembly 20 and the second clamping assembly 30 can approach and clamp electronic devices such as mobile phones. The connecting component 11 has a storage groove 13, and the rotating component 12 has an elastic element 14 that elastically engages with the storage groove 13. The rotating component 12 can drive the connecting component 11 to rotate. When the first clamping assembly 20 and the second clamping assembly 30 clamp the electronic device into place... The torque of the connector 11 is greater than the deformation force of the elastic member 14. The elastic member 14 rotates on the receiving groove 13 of the connector 11, and the rotating member 12 starts to spin freely. It cannot drive the connector 11 to continue to move, and thus cannot drive the first clamping component 20 and the second clamping component 30 to move. That is, after the first clamping component 20 and the second clamping component 30 are clamped in place, if the rotating member 12 is rotated again, the first clamping component 20 and the second clamping component 30 will not move closer again. This overload protection design avoids excessive clamping and damage to electronic devices such as mobile phones.

[0029] One end of the connector 11 extends to a rotating shaft 15, which is connected to the rotating member 12. In this embodiment, the elastic member 14 is a spring sheet.

[0030] Please see Figure 3The spring includes a connecting part 141 and a bending part 142. The connecting part 141 is connected to the bending part 142. The bending part 142 is accommodated in the storage groove 13 and elastically abuts against the storage groove 13. The connecting part 141 is connected to the rotating member 12.

[0031] Please see Figure 4 The axial rotation of the connector 11 drives the linear movement of the first clamping assembly 20. The first clamping assembly 20 includes a first clamping arm 21 and a first moving member 22 connected to each other. The second clamping assembly 30 includes a second clamping arm 31 and a second moving member 32 connected to each other. The first moving member 22 and the second moving member 32 are staggered, and the first clamping arm 21 and the second clamping arm 31 are arranged opposite to each other.

[0032] In this embodiment, the connecting member 11 is a screw, and the connecting member 11 is threadedly connected to the first moving member 22. When the connecting member 11 is rotated, the first moving member 22 moves closer to or further away from the second moving member 32.

[0033] The knob clamping bracket 10 also includes a housing 40 and a transmission assembly 50. The transmission assembly 50, the first moving member 22 and the second moving member 32 are housed in the housing 40. The first clamping arm 21 and the second clamping arm 31 are disposed on both sides of the housing 40. The transmission assembly 50 is connected to the first moving member 22 and the second moving member 32 respectively. The transmission assembly 50 controls the movement of the first moving member 22 and the second moving member 32.

[0034] The first movable member 22 is provided with a first protrusion 23, and the second movable member 32 is provided with a second protrusion 24. A spring 25 is provided on the first protrusion 23 and the second protrusion 24. The other end of the spring 25 is connected to the housing 40. One elastic end of the spring 25 is connected to the first protrusion 23 and the second protrusion 24, and the other elastic end of the spring 25 is connected to the housing 40.

[0035] The transmission assembly 50 includes a gear 51. The first moving member 22 has a first tooth 26, and the second moving member 32 has a second tooth 33. The gear 51 meshes with the first tooth 26 and the second tooth 33, and the gear 51 drives the first moving member 22 and the second moving member 32 to move closer or further apart. Specifically, rotating the connecting member 11 moves the first moving member 22 and drives the gear 51 to rotate. The gear 51 then drives the second moving member 32 to move, causing the first moving member 22 to move relative to the gear 22, that is, the first moving member 22 moves closer or further away from the gear 32.

[0036] Please see Figure 5 and Figure 6The second clamping arm 31 is provided with a limiting member 34, and the rotating member includes a supporting member 35. The supporting member 35 is connected to the limiting member 34. The supporting member 35 is provided with a receiving groove 38, which receives the elastic member 14.

[0037] The supporting member 35 is provided with a third protrusion 36, and the limiting member 34 is provided with a groove 37. The third protrusion 36 is connected to the groove 37, and the connecting member 11 passes through the limiting member 34 and the supporting member 35. When the third protrusion 36 is connected to the groove 37, the limiting member 34 contacts the supporting member 35 and restricts the movement of the supporting member 35.

[0038] The technical solution provided in this application embodiment may include the following beneficial effects: The present utility model provides a knob clamping bracket, including a first clamping component and a second clamping component that move relative to each other, a connecting component and a rotating component. The connecting component moves relative to the first clamping component. Both ends of the connecting component are connected to the rotating component and the first clamping component, respectively. The connecting component is provided with a storage groove. The rotating component is provided with an elastic component. The elastic component is elastically engaged with the storage groove. As the rotating component continues to rotate, the connecting component moves relative to the first clamping assembly, which in turn causes the first and second clamping assemblies to move relative to each other. The first and second clamping assemblies can approach and clamp electronic devices such as mobile phones. The connecting component has a storage groove, and the rotating component has an elastic element that elastically engages with the storage groove. The rotating component can drive the connecting component to rotate. When the first and second clamping assemblies clamp the electronic device into place, the torque of the connecting component exceeds the deformation force of the elastic element. The elastic element rotates on the storage groove of the connecting component, and the rotating component begins to spin freely, unable to drive the connecting component to continue moving. Consequently, it cannot drive the first and second clamping assemblies to move. This overload protection design avoids excessive clamping force and damage to electronic devices such as mobile phones.
