[0029] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0030] This embodiment discloses a terminal bracket for placing terminal electronic devices, for example, a smart phone, a tablet computer and other devices, and adjusting the terminal device to a suitable angle. Of course, other required terminal devices can also be placed.

[0031] like Figures 1 to 7 The terminal bracket includes a supporting base plate 1, a supporting arm 2 and a carrier plate 3.

[0032] The support base plate 1 is used to provide support force for the entire terminal bracket. The support arm 2 is located between the support base plate 1 and the carrier plate 3. The support arm 2 is used to lift the carrier plate 3 to a certain height above the support base plate 1. The carrier plate 3 is used to place the terminal device.

[0033] Specifically, the support arm 2 includes a first end 20 and a second end 21 relative to each other, and the second end 21 and the carrier plate 3 and / or the first end 20 and the support base plate 1 are connected via a pivot connection mechanism, so that the carrier plate 3 can swing back and forth in a vertical plane relative to the support arm 2 and / or the support arm 2 can swing relative to the support base plate 1, thereby adjusting the tilt angle of the carrier plate 3 or the support arm 2 to provide the user with a desired viewing angle.

[0034] When both ends of the support arm 2 are provided with a pivot connection mechanism having the above-mentioned structure, the vertical height of the carrier plate 3 relative to the supporting base plate 1 can be adjusted by adjusting the inclination angle of the support arm 2, and the inclination angle of the terminal device located on the carrier plate 3 can be adjusted by adjusting the inclination angle of the carrier plate 3 to meet the needs of the user.

[0035] For ease of explanation, in the following embodiments, the pivot connection mechanism is respectively configured at both ends of the support arm 2 , but the present invention is not limited thereto. That is, the pivot connection mechanism may be configured at one end of the support arm 2 .

[0036] The pivot connection mechanism includes a connection bracket 40 and a pivot shaft 41 .

[0037] When the support arm 2 and the carrier plate 3 are connected by the pivot connection mechanism, one end of the connection bracket 40 is connected to the carrier plate 3, and when the support arm 2 and the support base plate 1 are connected by the pivot connection mechanism, one end of the connection bracket 40 is connected to the support base plate 1. The other end of the connection bracket 40 is provided with a first through hole 400.

[0038] The first end 20 and the second end 21 of the support arm 2 are provided with a second through hole 22 , and the pivot shaft 41 is penetrated through the first through hole 400 and the second through hole 22 to connect the connecting bracket 40 with the support arm 2 and enable the connecting bracket 40 to rotate relative to the support arm 2 .

[0039] The pivot shaft 41 includes a pin shaft 42 and a cap 43. The pin shaft 42 includes a first rod portion 420 that can be inserted into the first through hole 400 and the second through hole 22 and a first blocking portion 421 located at one end of the first rod portion 420. The diameter of the first blocking portion 421 is greater than the diameter of the first through hole 400 and the second through hole 22, and the length of the second rod portion 430 is greater than the length of the second through hole 22. In this regard, the end of the pin shaft 42 away from the first blocking portion 421 can be inserted through one end of the first through hole 400 and the second through hole 22, and can be passed out through the other end of the first through hole 400 and the second through hole 22. Since the diameter of the first blocking portion 421 is greater than the diameter of the first through hole 400 and the second through hole 22, the pin shaft 42 can be prevented from being separated from the first through hole 400 and the second through hole 22.

[0040] In addition, a counterbore 422 extending along the axial direction of the first rod portion 420 is provided at one end of the first rod portion 420 away from the first blocking portion 421 .

[0041] The cap 43 includes a second rod portion 430 matched with the counterbore 422 and a second blocking portion 431 located at one end of the second rod portion 430 .

[0042] When the second rod portion 430 passes through the countersunk hole 422, the second blocking portion 431 is connected to the end of the first rod portion 420 away from the first blocking portion 421, and there is also an interference force between the first blocking portion 421 and the second blocking portion 431 and the connecting bracket 40, that is, the first blocking portion 421 and the second blocking portion 431 are attached to the two ends of the connecting bracket 40 with a certain pressure, so that the connecting bracket 40 and the support arm 2 can rotate relative to each other with damping.

[0043] Specifically, the second blocking portion 431 is riveted to an end of the first rod portion 420 away from the first blocking portion 421 , so as to effectively improve the stability of the connection between the pin shaft 42 and the cap 43 .

[0044] In this embodiment, the carrier plate 3 and the support arm 2, and the support arm 2 and the support base plate 1 are connected by a pivot connection mechanism including a connecting bracket 40 and a pivot shaft 41. The pin 42 and the cap 43 on the pivot shaft 41 allow the user to adjust the magnitude of the damping force as needed. The damping force is provided by the interference force (i.e., friction resistance) between the first blocking portion 421 and the second blocking portion 431 and the connecting bracket 40. Therefore, by matching the length between the counterbore 422 and the second rod 430, the tightness of the first blocking portion 421 and the second blocking portion 431 on the connecting bracket 40 can be adjusted to achieve the purpose of adjusting the magnitude of the damping force. When it is necessary to adjust the tilt angle of the carrier plate 3 and the support arm 2, it is only necessary to overcome the damping force. After adjusting to the target position, due to the existence of the damping force, the carrier plate 3 and the support arm 2 can be stabilized at this position.

[0045] Thus, the terminal bracket ensures the smoothness of the swing of the carrier plate 3 and the support arm 2, and enables the carrier plate 3 and the support arm 2 to stay stably at any position. In addition, the pivot connection mechanism has a simple structure, no unnecessary complex parts, and is easy to manufacture and maintain, which not only reduces the production cost, but also reduces potential failure points and improves the overall reliability.

[0046] On the other hand, a guard plate 30 is provided on the end of the carrier 3 opposite to the support arm 2, and the guard plate 30 abuts against the frame of the terminal device placed on the carrier 3. In this embodiment, the terminal device can be prevented from falling off the carrier 3 by setting the guard plate 30.

[0047] Furthermore, anti-slip pads 31 are provided on the carrier plate 3 and the guard plate 30 .

[0048] On the other hand, a rotating mechanism 5 is also provided on the support base plate 1, a rotating platform 6 is provided above the rotating mechanism 5, and the connecting bracket 40 is provided on the rotating platform 6. Based on the rotating mechanism 5, the rotating platform 6 can drive the connecting bracket 40 to rotate in a horizontal plane relative to the support base plate 1. In this embodiment, through the rotating mechanism 5 and the rotating platform 6, the support arm 2 can be rotated as needed to adjust the orientation of the terminal device located on the carrier plate 3.

[0049] On the other hand, Figures 8 to 10 The rotating mechanism 5 includes a fixed base 50 disposed on the supporting base plate 1 and a rotating base 51 sleeved on the fixed base 50. A rotating matching structure is disposed between the rotating base 51 and the fixed base 50. Based on the rotating matching structure, the rotating base 51 can rotate with damping relative to the fixed base 50. The rotating platform 6 is connected to the rotating base 51. In this embodiment, the fixed base 50 acts as a stator and the rotating base 51 acts as a mover. Therefore, the rotating base 51 rotates around the fixed base 50, thereby driving the rotating platform 6 to rotate in a horizontal plane.

[0050] On the other hand, the rotational matching structure includes a plurality of tooth grooves 511 and protrusions 504 arranged in an annular pattern, which are respectively arranged on opposite sides of the rotating base 51 and the fixed base 50. The protrusions 504 can abut against each tooth groove 511, and under the action of the rotational torque on the rotating base 51, each tooth groove 511 can be pushed to abut against the protrusions 504 one by one. In this embodiment, the tooth grooves 511 are arranged on the rotating base 51, and the protrusions 504 are arranged on the fixed base 50. When the rotational torque is applied to the rotating base 51, each tooth groove 511 arranged in an annular pattern abuts against the protrusions 504 one by one, so that the rotating platform 6 rotates. When the rotational torque disappears, the rotating base 51 is stabilized at this position due to the abutment of the protrusions 504 with the current tooth grooves 511.

[0051] Specifically, the rotating base 51 is provided with a first cavity 510, the tooth groove 511 is located on the inner wall of the first cavity 510, and the fixed base 50 is located in the first cavity 510. The fixed base 50 is fixedly connected to the supporting base plate 1, and the fixed base 50 is provided with a second cavity 500, and the protrusion 504 is located in the second cavity 500.

[0052] On the other hand, a spring sheet 502 is disposed in the second cavity 500, and a notch 501 facing the tooth groove 511 is also provided at the edge of the second cavity 500. The spring sheet 502 includes two oppositely disposed spring feet 503. The portion between the two spring feet 503 on the spring sheet 502 is bent outward to form a protrusion 504. The two spring feet 503 are used to abut against the inner walls of the second cavity 500 located on both sides of the notch 501, and the protrusion 504 enters and exits the second cavity 500 from the notch 501. In this embodiment, during the rotation of the rotating base 51, the driving protrusion 504 withdraws from the current tooth groove 511 and enters the second cavity 500. Then, when the notch 501 on the second cavity 500 is opposite to another adjacent tooth groove 511, the protrusion 504 enters the tooth groove 511 corresponding to the notch 501 under the elastic restoring force.

[0053] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
