[0002] With the continuous development of mobile terminals such as mobile phones, people are using them more and more frequently. In some situations, it is inconvenient to keep the mobile terminal in one's hand, such as when driving or in an office environment. This requires clamping devices to fix the mobile terminal. However, when the existing clamping devices are not in use, the clamping mechanism is in a movable state and is easily affected by external forces, which can cause shaking and affect the service life of the clamping mechanism.

[0024] This utility model has the following advantages: When a clamping device is needed to clamp and position a mobile terminal such as a mobile phone, the locking mechanism releases the locking of the relative bodies of the first and second clamping mechanisms. Then, the first and second clamping mechanisms are stretched to move away from each other. The mobile terminal to be clamped is placed between the first and second clamping mechanisms, and the first and second clamping mechanisms are driven to move closer together to clamp the mobile terminal, thereby achieving clamping and positioning of the mobile terminal. When clamping the mobile terminal is not needed, the locking mechanism locks the relative bodies of the first and second clamping mechanisms. This prevents the first and second clamping mechanisms from shaking or extending due to external interference, thereby reducing non-working movement of the first and second clamping mechanisms and improving their service life. Furthermore, when storing the clamping device, it avoids the first and second clamping mechanisms occupying more space or interfering with other items. Attached Figure Description

[0044] The following section will mainly describe the specific structure of the clamping device.

[0045] like Figure 1-4As shown, a clamping device 1 includes a main body 100, a first clamping mechanism 200, a second clamping mechanism 300, and a locking mechanism 400. The first clamping mechanism 200 is disposed on the main body 100, and the second clamping mechanism 300 is disposed opposite to the first clamping mechanism 200. The first clamping mechanism 200 and the second clamping mechanism 300 can move closer to or further away from each other to clamp or release a mobile terminal. The locking mechanism 400 passes through the main body 100, the first clamping mechanism 200, and the second clamping mechanism 300 in sequence. The locking mechanism 400 can move relative to the first clamping mechanism 200 and the second clamping mechanism 300 along its own axis to control the relative movement of the first clamping mechanism 200 and the second clamping mechanism 300 along the radial direction of the locking mechanism 400. Specifically, the locking mechanism 400 can move relative to the first clamping mechanism 200 and the second clamping mechanism 300 along its own axial direction to restrict the radial movement of the first clamping mechanism 200 and the second clamping mechanism 300 along the locking mechanism 400, or to remove the restriction on the radial movement of the first clamping mechanism 200 and the second clamping mechanism 300 along the locking mechanism 400, thereby achieving locking or unlocking of the first clamping mechanism 200 and the second clamping mechanism 300 relative to the main body 100. When the locking mechanism 400 moves relative to the first clamping mechanism 200 and the second clamping mechanism 300 in a first direction, it can restrict the radial movement of the first clamping mechanism 200 and the second clamping mechanism 300 along the locking mechanism 400. When the locking mechanism 400 moves relative to the first clamping mechanism 200 and the second clamping mechanism 300 in a direction opposite to the first direction, it can remove the restriction on the radial movement of the first clamping mechanism 200 and the second clamping mechanism 300 along the locking mechanism 400. In this embodiment, the first direction refers to... Figure 2 The direction indicated by the X-axis; the mobile terminal can be a mobile phone, tablet or other 3C products or other devices that need to be clamped.

[0046] When it is necessary to use the clamping device 1 to clamp and position mobile terminals such as mobile phones, the locking mechanism 400 releases the lock between the first clamping mechanism 200 and the second clamping mechanism 300 relative to the main body 100. Then, the first clamping mechanism 200 and the second clamping mechanism 300 are stretched to move away from each other. The mobile terminal to be clamped is placed between the first clamping mechanism 200 and the second clamping mechanism 300, and the first clamping mechanism 200 and the second clamping mechanism 300 are driven to move closer together. The device clamps a mobile terminal, thus achieving clamping and positioning of the mobile terminal. When clamping the mobile terminal is not needed, the locking mechanism 400 locks the first clamping mechanism 200 and the second clamping mechanism 300 relative to the main body 100. This prevents the first clamping mechanism 200 and the second clamping mechanism 300 from shaking or extending due to external forces, thereby reducing non-working movement of the first clamping mechanism 200 and the second clamping mechanism 300 and extending their service life. Furthermore, when storing the clamping device 1, it prevents the first clamping mechanism 200 and the second clamping mechanism 300 from occupying more space or interfering with other items.

[0047] refer to Figure 4 and Figure 6-9 The locking mechanism 400 includes a locking element 410, which includes a first locking part 411, a second locking part 412, and an operating part 413 arranged sequentially.

[0048] The first clamping mechanism 200 has a through-hole 2211A and a first guide groove 2211B that are connected to each other. The first locking part 411 is adapted to the first locking hole 2211A, and the width of the first guide groove 2211B is smaller than the diameter of the first locking hole 2211A. The second connector 321 has a through-hole 3211A and a second guide groove 3211B that are connected to each other. The second locking part 412 is adapted to the second locking hole 3211A, and the width of the second guide groove 3211B is smaller than the diameter of the second locking hole 2211A. The aperture of 3211A; the main body 100 has a first through hole 111, the operating part 413 is adapted to the first through hole 111, and the size of the second locking part 412 is not greater than the width of the first guide groove 2211B, and the width of the operating part 413 is not greater than the width of the second guide groove 3211B; the driving locking member 410 moves along its own axis relative to the main body 100, the first clamping mechanism 200 and the second clamping mechanism 300, so that the first locking part 411 is accommodated in the first locking hole 2211A, and the second locking part 41... The first clamping mechanism 200 and the second clamping mechanism 300 are accommodated in the second locking hole 3211A, and the operating part 413 is accommodated in the first through hole 111. Thus, the locking member 410 restricts the radial movement of the first clamping mechanism 200, the second clamping mechanism 300, and the main body 100 along the locking member 410, thereby locking the first clamping mechanism 200 and the second clamping mechanism relative to the main body 100; or the first locking part 411 extends out of the first locking hole 2211A, the second locking part 412 extends out of the second locking hole 3211A and is accommodated in the first locking hole 2211A, and the operating part 413... Part of the locking part 412 extends out of the first through hole 111 and is accommodated in the second locking hole 3211A. This lock restricts the radial movement of the main body 100 along the locking part 410 and removes the restriction on the radial movement of the first clamping mechanism 200 and the second clamping mechanism 300 along the locking part 410. Consequently, the first clamping mechanism 200 and the second clamping mechanism 300 are unlocked relative to the main body 100, allowing them to move along the extending directions of the first guide groove 2211B and the second guide groove 3211B. In this embodiment, the size of the second locking part 412 is slightly smaller than the width of the first guide groove 2211B, and the width of the operating part 413 is slightly smaller than the width of the second guide groove 3211B. This embodiment achieves locking of the first clamping mechanism 200 and the second clamping mechanism 300 relative to the main body 100 using only the locking part 410, resulting in reliable locking and a simple structure.

[0049] Specifically, when the first locking part 411 is accommodated in the first locking hole 2211A, the second locking part 412 is accommodated in the second locking hole 3211A, and the operating part 413 is accommodated in the first through hole 111, the operating part 413 is engaged in the first through hole 111 of the main body 100. Since the groove width of the first guide groove 2211B of the first clamping mechanism 200 is smaller than the hole diameter of the first locking hole 2211A, the first locking part 411 is engaged in the first locking hole 2211A, thus achieving locking. The component 410 limits the movement of the main body 100 and the first clamping mechanism 200, preventing the first clamping mechanism 200 from moving relative to the main body 100. Since the width of the second guide groove 3211B of the second clamping mechanism 300 is smaller than the diameter of the second locking hole 3211A, the second locking part 412 engages within the second locking hole 3211A, thus limiting the movement of the second clamping mechanism 300 relative to the main body 100. In this way, the first clamping mechanism 200 and the second clamping mechanism 300 are locked relative to the main body 100.

[0050] When the operating part 413 is driven to move the locking member 410 along its own axial direction, the first locking part 411 extends out of the first locking hole 2211A, the second locking part 412 extends out of the second locking hole 3211A and is accommodated in the first locking hole 2211A, and the operating part 413 is partially accommodated in the first through hole 111 and partially accommodated in the second locking hole 3211A, so that the main body 100 is always limited relative to the locking member 410. Since the size of the second locking part 412 is not greater than the width of the first guide groove 2211B, the second locking part 412 will not be limited in the first locking hole 2211A, that is, the first clamping mechanism 200 can move relative to the second locking part 412 along the first guide groove 2211B; since the width of the operating part 413 is not greater than the width of the second guide groove 3211B, the operating part 413 will not be limited in the second locking hole 3211A, that is, the second clamping mechanism 300 can move relative to the operating part 413 along the second guide groove 3211B. In this way, the locking between the first clamping mechanism 200 and the second clamping mechanism 300 and the main body 100 is released.

[0051] refer to Figure 2The locking mechanism 400 further includes a third elastic member 420 and a pressing member 430. The pressing member 430 is disposed at one end of the operating part 413 opposite to the second locking part 412. Pressing the pressing member 430 drives the operating part 413 to move axially along the locking member 410. One end of the third elastic member 420 abuts against the end of the first locking part 411 opposite to the second locking part 412, and the other end of the third elastic member 420 abuts against the main body 100. The third elastic member 420 is used to apply a reset elastic force toward the pressing member 430 to the locking member 410 when the first locking hole 2211A and the second locking hole 3211A are aligned with the locking member 410. In this embodiment, the pressing member 430 can be a button; the third elastic member 420 can be a spring.

[0052] Specifically, the third elastic element 420 enables the locking element 410 to automatically reset. After the clamping of the mobile terminal is released and the first clamping mechanism 200 and the second clamping mechanism 300 are reset, the first locking hole 2211A and the second locking hole 3211A are aligned with the locking element 410. Then, under the elastic force of the third elastic element 420, the locking element 410 and the pressing element 430 are reset, thereby restoring the locking of the first clamping mechanism 200 and the second clamping mechanism 300 relative to the main body 100.

[0053] refer to Figure 3-4 and Figure 6 The first clamping mechanism 200 includes a first clamping component 210 and a first elastic component 220 connected together. The first elastic component 220 is disposed on the main body 100. The second clamping mechanism 300 includes a second clamping component 310 and a second elastic component 320 connected together. The second elastic component 320 is disposed on the main body 100, and the second clamping component 310 is disposed opposite to the first clamping component 210. The first clamping component 210 and the second clamping component 310 can move closer to or further away from each other to drive the first elastic component 220 and / or the second elastic component 320 to extend or retract, thereby clamping or releasing the mobile terminal. In this embodiment, a first locking hole 2211A and a first guide groove 2211B are formed through the first elastic component 220, and a second locking hole 3211A and a second guide groove 3211B are formed through the second elastic component 320.

[0054] The first elastic component 220 includes a first connector 221 and a first elastic member 222 connected together. The first connector 221 is slidably disposed on the main body 100. One end of the first elastic member 222 away from the first connector 221 is connected to the main body 100, and the other end of the first connector 221 away from the first elastic member 222 is connected to the first clamping component 210. In this embodiment, a first locking hole 2211A and a first guide groove 2211B are formed through the first connector 221, and the first guide groove 2211B extends from the first locking hole 2211A toward the side away from the first clamping component 210. The first elastic member 222 may be, but is not limited to, a spring.

[0055] refer to Figure 3-4 and Figure 6 The second elastic component 320 includes a second connector 321 and a second elastic component 322 connected together. The second connector 321 is slidably disposed on the main body 100. One end of the second elastic component 322 away from the second connector 321 is connected to the main body 100, and the other end of the second connector 321 away from the second elastic component 322 is connected to the second clamping component 310. In this embodiment, a second locking hole 3211A and a second guide groove 3211B are formed through the second connector 321, and the second guide groove 3211B extends from the second locking hole 3211A toward the side away from the second clamping component 310. The second elastic component 322 may be, but is not limited to, a spring.

[0056] Specifically, when the first clamping assembly 210 and the second clamping assembly 310 move away from each other, the first connector 221 and the second connector 321 move with the first clamping assembly 210 and the second clamping assembly 310 respectively, so as to stretch the first elastic member 222 and the second elastic member 322. After the external force applied to the first clamping assembly 210 and the second clamping assembly 310 is removed, the first elastic member 222 and the second elastic member 322 retract, thereby driving the first clamping assembly 210 and the second clamping assembly 310 to move closer to each other to clamp the mobile terminal, and under the elastic force of the first elastic member 222 and the second elastic member 322, the mobile terminal is reliably clamped.

[0057] refer to Figure 4 and Figure 6-9 The locking mechanism 400 is used to lock or unlock the first connector 221 and the second connector 321 relative to the main body 100. Specifically, when the locking mechanism 400 locks the first connector 221 and the second connector 321 relative to the main body 100, the first clamping assembly 210 connected to the first connector 221 and the second clamping assembly 310 connected to the second connector 321 are also locked relative to the main body 100. Consequently, the first elastic member 222 and the second elastic member 322 will not be stretched by the first clamping assembly 210 and the second clamping assembly 310.

[0058] When the clamping device 1 is needed to clamp and position a mobile terminal such as a mobile phone, pressing the pressing member 430 drives the locking member 410 to move, thereby releasing the lock between the first connecting member 221 and the second connecting member 321 relative to the main body 100. Then, the first clamping assembly 210 and the second clamping assembly 310 are stretched, so that the first elastic member 222 and the second elastic member 322 are elastically stretched through the first connecting member 221 and the second connecting member 321. After the first clamping assembly 210 and the second clamping assembly 310 are released, under the elastic action of the first elastic member 220 and the second elastic member 320, the first clamping assembly 210 and the second clamping assembly 310 move closer to each other to clamp the mobile terminal, thereby achieving clamping and positioning of the mobile terminal. When the mobile terminal is no longer needed and is removed from the clamping device, the first elastic member 222 and the second elastic member 322 elastically retract, so that the first connecting member 221 and the second elastic member 322 retract, thereby releasing the lock between the first connecting member 221 and the second elastic member 322. 1. The first clamping component 210 and the second clamping component 310 move closer to each other to achieve a reset, thereby aligning the first locking hole 2211A of the first connector 221 and the second locking hole 3211A of the second connector 321 with the locking component 410. Then, under the elastic force of the third elastic component 420, the locking component 410 and the pressing component 430 reset, thereby re-locking the first clamping mechanism 200 and the second clamping mechanism 300 relative to the main body 100. This locks the first clamping component 210 and the second clamping component 310 relative to the main body 100. In this way, the first clamping mechanism 200 and the second clamping mechanism 300 will not wobble or stretch due to external interference, thereby reducing the non-working stretching and contraction of the first elastic component 222 and the second elastic component 322, and thus improving the service life of the first elastic component 222 and the second elastic component 322. In addition, it can also prevent the first elastic member 222 and the second elastic member 322 from popping apart and taking up more space or interfering with other items when storing the clamping device 1.

[0059] Specifically, when it is necessary to clamp a mobile terminal, the first clamping component 210 and the second clamping component 310 are generally pulled simultaneously to stretch the first elastic component 220 and the second elastic component 320, causing the first clamping component 210 and the second clamping component 310 to move away from each other, so that there is enough space between the first clamping component 210 and the second clamping component 310 to clamp the mobile terminal such as a mobile phone. However, depending on the usage requirements, only the first clamping component 210 or the second clamping component 310 can be pulled relative to the main body 100. In this case, the distance between the first clamping component 210 and the second clamping component 310 will still increase, making it easier to place the mobile terminal such as a mobile phone between the first clamping component 210 and the second clamping component 310. After releasing the first clamping component 210 or the second clamping component 310, when the first elastic component 220 or the second elastic component 320 elastically retracts, the distance between the first clamping component 210 and the second clamping component 310 gradually decreases to clamp the mobile terminal such as a mobile phone.

[0060] refer to Figure 1-4 The first clamping assembly 210 includes a first mounting member 211, a first rotating shaft 212 disposed on the first mounting member 211, and a first clamping member 213 rotatably disposed on the first rotating shaft 212. The first mounting member 211 is connected to the first connecting member 221, and the first clamping member 213 can rotate around the first rotating shaft 212 to open or fold relative to the main body 100.

[0061] refer to Figure 1-4 The second clamping assembly 310 includes a second mounting member 311, a second rotating shaft 312 disposed on the second mounting member 311, and a second clamping member 313 rotatably disposed on the second rotating shaft 312. The second mounting member 311 is connected to the second connecting member 321, and the second clamping member 313 can rotate around the second rotating shaft 312 to open or fold relative to the main body 100.

[0062] refer to Figure 1-3 The first mounting member 211 has a first limiting part 2111, which is used to limit the rotation angle of the first clamping member 213. Specifically, during the rotation of the first clamping member 213 around the first rotating shaft 212, when the rotating end of the first clamping member 213 abuts against the first limiting part 2111, the first clamping member 213 is limited and cannot continue to rotate, thereby realizing the limitation of the rotation angle of the first clamping member 213. The first clamping member 213 includes a clamping end and a rotating end. The clamping end of the first clamping member 213 is used to clamp the mobile terminal, and the other end of the first clamping member 213 is the rotating end.

[0063] refer to Figure 1-3The second mounting member 311 has a second limiting part 3111, which is used to limit the rotation angle of the second clamping member 313. Specifically, during the rotation of the second clamping member 313 around the second rotation axis 312, when the rotating end of the second clamping member 313 abuts against the second limiting part 3111, the second clamping member 313 is limited and cannot continue to rotate, thereby realizing the limitation of the rotation angle of the second clamping member 313. The second clamping member 313 includes a clamping end and a rotating end. The clamping end of the second clamping member 313 is used to clamp the mobile terminal, and the other end of the second clamping member 313 is the rotating end.

[0064] In this embodiment, the maximum rotation angle of the first clamping member 213 relative to the first rotating shaft 212 is 90 degrees, and the maximum rotation angle of the second clamping member 313 relative to the second rotating shaft 312 is 90 degrees. This arrangement ensures that when the first clamping member 213 and the second clamping member 313 are opened relative to the main body 100, the first clamping member 213 and the second clamping member 313 are approximately perpendicular to the top surface of the main body 100, thereby making the first clamping member 213 and the second clamping member 313 approximately parallel, so as to better clamp the mobile terminal.

[0065] refer to Figure 4 The first clamping member 213 and the second clamping member 313 each have a buffer member 2131 on the side used to clamp the mobile terminal. Specifically, during the clamping process of the mobile terminal, the buffer member 2131 can increase the friction between the mobile terminal and the first clamping member 213 and the second clamping member 313, and prevent scratches from forming on the surface of the mobile terminal. The buffer member 2131 can be made of elastic materials such as foam plastic or rubber.

[0066] refer to Figure 4 The middle part of the buffer 2131 is recessed inward. The first clamping member 213 and the second clamping member 313 can better clamp the mobile terminal through the recessed part of the buffer 2131, so that the clamping and limiting of the mobile terminal is more reliable.

[0067] refer to Figure 6-9The first connecting member 221 includes a first connecting plate 2211 and at least two first connecting posts 2212 connected to the first connecting plate 2211. The number of first elastic members 222 is the same as the number of first connecting posts 2212 and they correspond one-to-one. One end of each first connecting post 2212 is connected to the first clamping assembly 210, and the other end of each first connecting post 2212 is connected to its corresponding first elastic member 222. One end of each first elastic member 222 facing away from the corresponding first connecting member 221 is connected to the main body 100. The partition plate 120 has a first receiving guide groove 123. The number of first receiving guide grooves 123 is the same as the number of first connecting posts 2212 and they correspond one-to-one. Each first connecting post 2212 is slidably disposed in the corresponding first receiving guide groove 123. In this embodiment, the first locking hole 2211A and the first guide groove 2211B are opened through the first connecting plate 2211; at least two first connecting posts 2212 are integrally formed with the first connecting plate 2211.

[0068] Specifically, two or more first connecting posts 2212 cooperate with the two first elastic members 222 to make the movement of the first connecting member 221 more stable and reliable; the first receiving guide groove 123 guides the first connecting posts 2212, thereby making the movement of the first connecting plate 2211 more stable and accurate, and preventing the first connecting plate 2211 from deviating or misaligning. In this embodiment, there are two first connecting posts 2212. It is understood that in other embodiments, there may be more first connecting posts 2212.

[0069] Furthermore, a shock-absorbing structure is provided inside the first connecting column 2212. The shock-absorbing structure is used to dampen the first elastic element 222 when it rebounds, so as to slowly release the elastic force and reduce the impact on the first clamping assembly 210. The shock-absorbing structure can be a spring, a spring sheet or a damping structure.

[0070] refer to Figure 6-11 Furthermore, a first limiting post 2213 is provided on the side wall of the first connecting post 2212, and a first limiting block 112 is correspondingly provided on the main body 100. The first limiting block 112 is used to stop the first limiting post 2213. Specifically, when the first clamping component 210 and the second clamping component 310 are pulled away from each other, the first connecting post 2212 gradually moves away from the second clamping component 310 along with the first clamping component 210 until the first limiting post 2213 abuts against the first limiting block 112, at which point the first clamping component 210 can no longer be pulled.

[0071] refer to Figure 6-9The second connector 321 includes a second connecting plate 3211 and at least two second connecting posts 3212 connected to the second connecting plate 3211. The number of second elastic members 322 is the same as the number of second connecting posts 3212 and they correspond one-to-one. One end of each second connecting post 3212 is connected to the second clamping assembly 310, and the other end of each second connecting post 3212 is connected to its corresponding second elastic member 322. One end of each second elastic member 322 facing away from the corresponding second connector 321 is connected to the main body 100. The partition plate 120 has a second receiving guide groove 124. The number of second receiving guide grooves 124 is the same as the number of second connecting posts 3212 and they correspond one-to-one. Each second connecting post 3212 is slidably disposed in the corresponding second receiving guide groove 124. Specifically, two or more second connecting posts 3212 cooperate with the two second elastic members 322 to make the movement of the second connecting member 321 more stable and reliable; the second receiving guide groove 124 is provided to guide the second connecting posts 3212, thereby making the movement of the second connecting plate 3211 more stable and accurate, and avoiding deviation or misalignment of the second connecting plate 3211. In this embodiment, there are two second connecting posts 3212. It can be understood that in other embodiments, there may be more second connecting posts 3212. Furthermore, in this embodiment, at least two second connecting posts 3212 are integrally formed with the second connecting plate 3211.

[0072] Furthermore, a shock-absorbing structure is provided inside the second connecting column 3212. The shock-absorbing structure is used to dampen the second elastic element 322 when it rebounds, so as to slowly release the elastic force and reduce the impact on the second clamping assembly 310. The shock-absorbing structure can be a spring, a spring sheet or a damping structure.

[0073] refer to Figure 6-11 Furthermore, a second limiting post 3213 is provided on the side wall of the second connecting post 3212, and a second limiting block 125 is correspondingly provided on the main body 100. The second limiting block 125 is used to stop the second limiting post 3213. Specifically, when the first clamping component 210 and the second clamping component 310 are pulled away from each other, the second connecting post 3212 gradually moves away from the first clamping component 210 along with the second clamping component 310 until the second limiting post 3213 abuts against the second limiting block 125, at which point the second clamping component 310 can no longer be pulled.

[0074] refer to Figure 2 and Figure 5The main body 100 includes a first housing 110, a partition plate 120, and a second housing 130. The first housing 110 covers the second housing 130, and the partition plate 120 is disposed between the first housing 110 and the second housing 130. A first clamping mechanism 200 and a second clamping mechanism 300 are disposed on the side of the partition plate 120 facing the first housing 110. In this embodiment, a first limiting block 112 is disposed on the first housing 110, and a second limiting block 125 is disposed on the partition plate 120.

[0075] Specifically, the first connector 221 is slidably disposed on the partition plate 120, the first elastic component 220 is disposed between the first housing 110 and the partition plate 120, and the end of the first elastic component 222 opposite to the first connector 221 is connected to the partition plate 120. A first through hole 111 is formed on the first housing 110. The second connector 321 is slidably disposed on the partition plate 120, the second elastic component 320 is disposed between the first housing 110 and the partition plate 120, and the end of the second elastic component 322 opposite to the second connector 321 is connected to the partition plate 120.

[0076] In this embodiment, the first clamping member 213 can rotate around the first rotating axis 212 to open or fold relative to the first housing 110, and the second clamping member 313 can rotate around the second rotating axis 312 to open or fold relative to the first housing 110. Thus, when it is necessary to clamp the mobile terminal, the first clamping member 213 and the second clamping member 313 are opened relative to the first housing 110, and the mobile terminal is clamped between the first clamping member 213 and the second clamping member 313 with the cooperation of other structures. Thus, when it is not necessary to clamp the mobile terminal, the first clamping member 213 and the second clamping member 313 are folded relative to the first housing 110, thereby further reducing the space occupied by the clamping device 1 and overcoming the defects of the prior art where the clamping member occupies a large space and is not convenient to store.

[0077] refer to Figure 6 and Figure 10-11 The partition plate 120 is provided with a first protrusion 121 and a second protrusion 122. The number of first protrusions 121 is the same as the number of first elastic members 222 and they correspond one-to-one. The end of the first elastic member 222 facing away from the first connecting member 221 is connected to the first protrusion 121. The number of second protrusions 122 is the same as the number of second elastic members 322 and they correspond one-to-one. The end of the second elastic member 322 facing away from the second connecting member 321 is connected to the second protrusion 122. The first protrusion 121 and / or the second protrusion 122 may also be provided on the first housing 110. In one embodiment, the first protrusion 121 is provided on the first housing 110, and the second protrusion 122 is provided on the partition plate 120.

[0078] refer to Figure 1The clamping device 1 also includes a heat sink 500, which is disposed on the side of the first housing 110 opposite to the second housing 130. The heat sink 500 has multiple heat dissipation holes 510 spaced apart on it and is used to support the mobile terminal. Specifically, the mobile terminal generates heat during use or charging, and the heat dissipation holes 510 help dissipate heat. In other embodiments, auxiliary heat dissipation structures such as cooling fans can be provided on or within the heat sink 500 to accelerate the cooling process of the mobile terminal.

[0079] In this embodiment, refer to Figure 1-2 When the first clamping member 213 and the second clamping member 313 are folded relative to the first housing 110, both the first clamping member 213 and the second clamping member 313 are flush with the heat sink 500, thus occupying less space. When the first clamping member 213 and the second clamping member 313 are opened relative to the first housing 110, both the first clamping member 213 and the second clamping member 313 are perpendicular to the heat sink 500, so that the opposing surfaces of the first clamping member 213 and the second clamping member 313 are used to clamp the mobile terminal.

[0080] refer to Figure 1 The heat sink 500 has a second through hole 520 at the position corresponding to the first through hole 111. The second through hole 520 is used to accommodate the pressing member 430 of the locking mechanism 400. In another embodiment, the pressing member 430 is exposed in the second through hole 520, which facilitates pressing the pressing member 430. When the mobile terminal is clamped on the heat sink 500, the mobile terminal squeezes the pressing member 430, so that the first connecting member 221 and the second connecting member 321 are maintained in a locked state relative to the main body 100.

[0081] like Figure 1 and Figure 14 As shown, a fixed bracket includes a mounting base 2 and the aforementioned clamping device 1, which are detachably connected to the mounting base 2. Specifically, the detachable connection between the clamping device 1 and the mounting base 2 can be achieved through snap-fit, threaded engagement, plug-in connection, bolt connection, magnetic engagement, etc., as long as it enables the detachable connection between the clamping device 1 and the mounting base 2.

[0082] In this embodiment, the fixed bracket is used on a vehicle, the mounting base 2 is installed on the vehicle's air vent or other suitable structure, and the clamping device 1 is used to clamp the mobile phone. It is understood that in other embodiments, the fixed bracket can also be used on a fixed structure such as a table or a mobile structure such as a bicycle, and the clamping device 1 can also be used to clamp other electronic products such as a tablet computer. The mounting base 2 is detachably installed on the vehicle's air vent or other suitable structure. Detachable installation can be achieved through snap-fit, threaded connection, plug-in connection, bolt connection, or magnetic attraction. In other embodiments, the mounting base 2 can also be installed on the vehicle's air vent or other suitable structure via a universal ball joint, thereby enabling adjustment of the mounting base 2 at multiple angles.

[0083] refer to Figure 1 and 12 -14, the mounting base 2 has a mating groove 810, and the inner side wall of the mating groove 810 has two oppositely arranged retaining grooves 811; the clamping device 1 also includes a retaining mechanism 600, which is disposed in the second housing 130 and located between the second housing 130 and the partition plate 120. The retaining mechanism 600 includes a control component 610 and two oppositely arranged retaining members 620. The control component 610 is in transmission cooperation with the two retaining members 620 respectively. The two retaining members 620 each have a retaining part 623, which extends out of the second housing 130. The control component 610 is used to drive the two retaining members 620 to move closer or further away from each other, so that the retaining parts 623 of the two retaining members 620 are engaged or disengaged from the two retaining grooves 811. Specifically, the mounting base 2 is installed on an external structure such as a vehicle. Then, the control component 610 drives the two holding members 620 to move closer to each other. After aligning the two holding members 620 with the two holding slots 811, the control component 610 drives the two holding members 620 to move away from each other so as to engage with the two holding slots 811, thereby achieving the engagement between the clamping device 1 and the mounting base 2.

[0084] refer to Figure 12The control assembly 610 includes a fourth elastic member 611 and two opposing control members 612. The fourth elastic member 611 abuts against or connects between the two retaining members 620. The two control members 612 abut against the two retaining members 620 respectively. Pushing the two control members 612 can cause the two retaining members 620 to move closer to each other. The fourth elastic member 611 is used to apply an elastic force to the two retaining members 620 to move them away from each other. Specifically, the mounting base 2 is mounted on an external structure such as a vehicle. Then, the two control members 612 are pushed to cause the two retaining members 620 to move closer to each other against the elastic force of the fourth elastic member 611. After aligning the two retaining members 620 with the two retaining slots 811, the two control members 612 are released. Subsequently, the fourth elastic member 611 rebounds to cause the two retaining members 620 to move away from each other, thereby causing the two retaining members 620 to engage with the two retaining slots 811, thus realizing the engagement between the clamping device 1 and the mounting base 2. Conversely, when the clamping device 1 is engaged with the mounting base 2, pushing the two control members 612 causes the two clamping members 620 to overcome the elastic force of the fourth elastic member 611 and move closer to each other, thereby causing the two clamping members 620 to disengage from the two clamping slots 811. In this way, the clamping device 1 can be removed from the mounting base 2 by disengaging the clamping device 1. In this embodiment, the fourth elastic member 611 can be a spring.

[0085] In this embodiment, the fourth elastic member 611 abuts against the two retaining members 620. Guide posts 621 are respectively provided on opposite sides of the two retaining members 620. One end of the fourth elastic member 611 is sleeved on the guide post 621 of one retaining member 620, and the other end of the fourth elastic member 611 is sleeved on the guide post 621 of the other retaining member 620. The guide posts 621 prevent the fourth elastic member 611 from deviating from the two retaining members 620 during extension and retraction.

[0086] refer to Figure 12 Furthermore, the central axis of the two control members 612 is perpendicular to the central axis of the two holding members 620. Each of the two holding members 620 has two first extensions 622 that extend obliquely toward the other holding member 620. The distance between the two first extensions 622 of each holding member 620 gradually increases along the direction from one holding member 620 to the other holding member 620. Each of the two control members 612 has two second extensions 6121 that extend obliquely toward the other control member 612. The distance between the two second extensions 6121 of each control member 612 gradually increases along the direction from one control member 612 to the other holding member 612. The inner sidewalls of the two second extensions 6121 of each control member 612 abut against the outer sidewalls of the first extensions 622 of the two holding members 620 that are closer to the current control member 612.

[0087] Specifically, the mounting base 2 is installed on an external structure such as a vehicle. Then, the two control members 612 are pushed closer to each other. The inner walls of the two second extensions 6121 of one control member 612 abut against the outer walls of the first extensions 622 on the same side of the two retaining members 620. The inner walls of the two second extensions 6121 of the other control member 612 abut against the outer walls of the first extensions 622 on the other side of the two retaining members 620. After the first extensions 622 of the retaining members 620 are abutted, the two retaining members 620 are driven to overcome the elastic force of the fourth elastic member 611 and move closer to each other. After aligning the two retaining members 620 with the two retaining slots 811, the two control members 612 are released. Then, the fourth elastic member 611 rebounds to drive the two retaining members 620 away from each other, so that the two retaining members 620 are engaged in the two retaining slots 811, thereby realizing the engagement between the clamping device 1 and the mounting base 2.

[0088] refer to Figure 1 , Figure 3 and Figure 12-13 Each of the two control components 612 has a pressing component 630 on its opposite side. The pressing components 630 are partially exposed on the side wall of the main body 100, allowing two fingers to simultaneously press both pressing components 630 during use to bring the two holding components 620 closer together. Specifically, the side wall of the second housing 130 has two opposing pressing holes 132, through which the two pressing components 630 are partially exposed on the side wall of the main body 100.

[0089] refer to Figure 13 The second housing 130 has a receiving and limiting groove 131 adapted to the holding mechanism 600 on the side facing the first housing 110 to ensure the accuracy and reliability of the movement of the two operating members 612 and the two holding members 620. Furthermore, the bottom of the receiving and limiting groove 131 has two holding openings 1311 corresponding to the two holding members 620, and the two holding members 620 extend partially out of the receiving and limiting groove 131 through the two holding openings 1311 respectively.

[0090] refer to Figure 3 and Figure 14 The second housing 130 is covered with a first cover 140 on the side opposite to the first housing 110. The first cover 140 covers the second housing 130 at the position corresponding to the receiving and limiting groove 131. The mounting base 2 is covered with a second cover 820 for covering the bottom of the mating groove 810, and the two retaining grooves 811 are exposed outside the second cover 820. Specifically, the arrangement of the first cover 140 and the second cover 820 makes the clamping device 1 and the mounting base 2 look more aesthetically pleasing. Both the first cover 140 and the second cover 820 are sheet-like structures, and when the clamping device 1 and the mounting base 2 are engaged, the first cover 140 and the second cover 820 fit flush with each other.

[0091] refer to Figure 14 The mounting base 2 includes a connecting base 700, a mating part 800, and a charging cable 900. The mating part 800 is disposed on the connecting base 700, and a mating groove 810 is formed in the mating part 800. A receiving space is formed inside the connecting base 700, and a spiral spring (not shown) is disposed in the receiving space. The charging cable 900 is tightly fitted with the spiral spring, and one end of the charging cable 900 has a charging interface that extends out of the receiving space. The charging interface is used to connect to the charging port of the mobile terminal. Specifically, because the spiral spring has the characteristics of having a large number of coils and a large deformation angle, it can store more energy in a small volume. Therefore, when the spiral spring is unwound, the deformation energy is released, achieving the effect of storing and organizing the charging cable 900.

[0092] In another embodiment, a wireless charging mechanism is provided within the clamping device 1 or the mounting base 2 for wirelessly charging the mobile terminal. The wireless charging mechanism in this application adopts an existing wireless charging structure, as long as it can wirelessly charge the mobile terminal; for example, the wireless charging mechanism is a wireless charging disc.
