DETAILED DESCRIPTION

[0035] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0036] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0037] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0038] The vehicle screen holder can fix the mobile device on the vehicle screen so that the driver can simultaneously observe the vehicle information displayed on the vehicle screen and the information displayed on the mobile device. The mobile device can be an electronic device such as a mobile phone or a tablet computer.

[0039] However, current vehicle screen brackets are mostly fixed to the vehicle screen by tightening bolts and nuts to push a pressure plate to press against the vehicle screen. Since there is no position restriction structure between the bolts and nuts, the vehicle screen may be damaged if the bolts and nuts are tightened continuously.

[0040] In response to the above problems, the present application provides a vehicle-mounted screen bracket, which can prevent excessive tightening from causing the pressure plate to continuously squeeze the vehicle-mounted screen when the tightening force of the bolts and nuts reaches a level that can cause the force-unloading deformation structure to deform, thereby avoiding damage to the vehicle-mounted screen.

[0041] See also Figure 1-Figure 4 As shown, the vehicle-mounted screen bracket provided in the present application includes: a clamping assembly 10 and a locking assembly 20,

[0042] The clamping assembly 10 includes a body 11, a fixed component 12 and a movable component 13. The body 11 is provided with a connecting portion 111 for connecting the mobile terminal 100. The fixed component 12 is used to be fixed to the edge of the vehicle screen 200. The movable component 13 is connected to the body 11 in a non-rotatable manner and can be moved toward or away from the body 11. When moving in a direction away from the body 11, it can contact the vehicle screen, and then the vehicle screen 200 can be clamped by the cooperation of the fixed component 12 and the movable component 13. Figure 1 As shown, Figure 1 2 is a schematic diagram showing that a vehicle screen bracket connected with a mobile device 100 is connected to a vehicle screen 200, with the back of the vehicle screen as the viewing angle.

[0043] It can be understood that the fixed component 12 is fixed to the edge of the vehicle screen 200. After the movable component 13 moves away from the main body 11 and contacts the vehicle screen 200, it can press against the vehicle screen 200, thereby cooperating with the fixed component 12 to clamp the vehicle screen 200.

[0044] In some embodiments, a connecting structure 300 is further provided on the connecting portion 111, one end of the connecting structure 300 is rotatably connected to the connecting portion 111, and the mobile device 100 is fixed to the other end of the connecting structure 300. Through the rotatable connection of the connecting structure 300, the angle of the mobile device can also be adjusted.

[0045] The locking assembly 20 includes an operating member 21, a transition member 22 and a transmission member 23. One end of the transition member 22 is connected to one end of the transmission member 23, and the other end of the transition member 22 is connected to the operating member 21. The transmission member 23 is rotatably mounted on the body 11, and the other end of the transmission member 23 is connected to the movable component 13.

[0046] In this embodiment, by operating the operating member 21, the transmission member 23 can be driven to rotate through the transition member 22, so that the movable component 13 can move in a direction toward or away from the main body 11, and when the movable component 13 moves in a direction away from the main body 11 and contacts the vehicle-mounted screen 200, the connection between the operating member 21 and the transition member 22 or between the transition member 22 and the transmission member 23 can be invalidated, and the operating member 21 or the transition member 22 can be kept able to continue to move, thereby preventing the movable component 13 from continuing to move away from the main body 11 after contacting the vehicle-mounted screen 200, thereby preventing the movable component 13 from causing damage to the vehicle-mounted screen 200.

[0047] Continue to see Figure 1 As shown, two fixing components 12 are provided on the body 11, and the two fixing components 12 are arranged at 90 degrees, so that the two fixing components 12 can be clamped on the adjacent two sides of the vehicle-mounted screen 200, respectively. Figure 2As shown, the two fixing components 12 may be of the same concave shape as the side of the vehicle-mounted screen 200 , so that the two fixing components 12 may be respectively inserted into the adjacent two side edges of the vehicle-mounted screen 200 .

[0048] In this embodiment, a fixing component buffer pad 121 is further provided on the fixing component 12 to buffer the side of the vehicle-mounted screen 200 to further avoid damage to the vehicle-mounted screen 200 .

[0049] The fixing component buffer pad 121 can be made of materials such as rubber and silicone.

[0050] In this embodiment, after the fixed component 12 is clamped on the vehicle screen 200 in cooperation with the movable component 13, the body 11 can be located on the back of the vehicle screen 200. The body 11 is provided with an axial hole 112, which is perpendicular to the vehicle screen 200. A plurality of slots 221 are provided in the circumference of the transition piece 22. In a preferred embodiment, the plurality of slots 221 are provided in an array of equally divided circles on the outer circumference of the transition piece 22. The transmission piece 23 is provided with an external thread 231, the movable component 13 is provided with an internal screw hole 131, the internal screw hole 131 is screwed with the external thread 231, the operating piece 21 is sleeved on the transition piece 22, the inner circumference of the operating piece 21 is provided with a force unloading deformation structure 211, the force unloading deformation structure 211 is provided with a clamping tooth 2111, the clamping tooth 2111 is clamped in the clamping groove 221, and the force unloading deformation structure 21 can produce a contraction deformation when subjected to a preset deformation force.

[0051] The shaft hole 112 is disposed toward the back of the vehicle screen 200, and when the operating member 21 rotates in the locking direction, the movable member 13 can convert the synchronous rotational motion of the transmission member 23 and the operating member 21 into a linear motion along the axial direction of the shaft hole 112, so that the movable member 13 faces the back of the vehicle screen 200, thereby fixing the vehicle screen bracket on the vehicle screen 200. For details, please refer to the following embodiments.

[0052] By rotating the operating member 21, the transmission member 23 can be driven to rotate synchronously by the cooperation of the latch teeth 212 and the latch slot 221, and the movable member 13 can convert the rotational motion of the transmission member 23 into a linear motion to move in a direction toward or away from the body 11, and in the process of moving in a direction away from the body 11, the vehicle screen bracket is fixed on the vehicle screen 200 by abutting against the back of the vehicle screen 200 in cooperation with the fixing member 12. When the movable member 13 moves in a direction toward the body 11, the movable member 13 can be separated from the back of the vehicle screen 200 to release the connection between the vehicle screen bracket and the vehicle screen 200. For the convenience of distinction in the following embodiments, the rotation direction of the operating member 21 when the movable member 13 moves in a direction away from the body 11 is defined as the locking direction, and the rotation direction of the operating member 21 when the movable member 13 moves in a direction toward the body 11 is defined as the unlocking direction.

[0053] Specifically, by rotating the operating member 21 along the locking direction, the transmission member 23 can be driven to rotate synchronously along the locking direction around the axis of the shaft hole 112 through the cooperation of the locking teeth 212 and the locking groove 221, so that the movable component 13 moves a preset distance in the direction away from the main body 11 and presses the vehicle screen 200. In other words, when the movable component 13 moves a preset distance in the direction away from the main body 11, it can press the vehicle screen 200, thereby fixing the vehicle screen bracket on the vehicle screen 200. During the rotation of the transmission member 23, a locking force is generated between the external thread 231 on the transmission member 23 and the internal screw hole 131 on the movable member 13. After the movable member 13 moves a preset distance away from the main body 11, the external thread 231 and the internal screw hole 131 generate a locking force greater than or equal to the preset deformation force. Under the action of the preset deformation force, the force-unloading deformation structure 211 is deformed, so that the latch tooth 212 jumps over the current latch slot 221, thereby preventing over-rotation from causing the movable member 13 to continue to move away from the main body 11, so as to avoid continuing to apply pressure to the vehicle-mounted screen 200, thereby preventing damage to the vehicle-mounted screen 200.

[0054] When the operating member 21 is rotated along the unlocking direction, the transmission member 23 can be driven to rotate synchronously along the unlocking direction around the axial center line of the shaft hole 112 through the cooperation of the latch tooth 212 and the latch slot 221, so that the movable part 13 moves toward the main body 11 to disengage from the vehicle screen 200, thereby releasing the connection between the vehicle screen bracket and the vehicle screen 200.

[0055] By setting the force-releasing deformation structure 211, the present application can make the force-releasing deformation structure 211 deform during the process of rotating the operating part 21 along the locking direction. When the locking force between the external thread 231 of the transmission part 23 and the internal screw hole 131 of the movable part 13 is greater than the preset deformation force that the force-releasing deformation structure 211 can withstand, so that the locking tooth 212 can skip the current slot 221 and be inserted into the next slot 221, thereby preventing the movable part 13 from continuing to move away from the main body 11 due to overrotation, so as to prevent the movable part 13 from continuing to apply pressure to the vehicle-mounted screen 200, thereby preventing damage to the vehicle-mounted screen 200.

[0056] See also Figure 7 As shown, the force-unloading deformation structure 211 is provided with a hollow deformation avoidance portion 213. The setting of the hollow deformation avoidance portion 213 can avoid the deformation of the force-unloading deformation structure 211, so that the force-unloading deformation structure 211 is deformed toward the inner periphery of the operating member 21, thereby driving the latch tooth 212 to retract toward the direction of the inner periphery of the operating member 21 so as to skip the current latch slot 221.

[0057] In a specific embodiment, the force unloading deformation structure 211 includes a first deformation connection member 2111, a second deformation connection member 2112 and a third deformation connection member 2113, one end of the first deformation connection member 2111 is connected to the inner periphery of the operating member 21, one end of the second deformation connection member 2112 is connected to the other end of the first deformation connection member 2111, the other end of the second deformation connection member 2112 is connected to one end of the third deformation connection member 2113, and the other end of the third deformation connection member 2113 is connected to the inner periphery of the operating member 21, so that the first deformation connection member 2111, the second deformation connection member 2112, the third deformation connection member 2113 and the inner periphery of the operating member 21 are combined to form a hollow deformation avoidance portion 213. The latching teeth 212 are arranged at the connection between the second deformation connection member 2112 and the third deformation connection member 2113.

[0058] In this embodiment, the first deformable connector 2111, the second deformable connector 2112, and the third deformable connector 2113 can all be deformed under stress, and the combined shape of the first deformable connector 2111, the second deformable connector 2112, the third deformable connector 2113 and the inner periphery of the operating member 21 is basically a trapezoidal structure, so that the shape of the hollow deformable avoidance portion 213 is formed into a trapezoid, wherein the first deformable connector 2111 and the third deformable connector 2113 form two waists of the trapezoidal structure, and the second deformable connector 2112 and the inner periphery of the operating member 21 respectively form the upper base and lower base of the trapezoidal structure.

[0059] In one embodiment of the present application, Figure 7The angle α between the third deformable connector 2113 and the tangent passing through the connection between the third deformable connector 2113 and the inner periphery of the operating member 21 is an acute angle, so that the force-releasing deformable structure 211 can be deformed toward the inner periphery of the operating member 21 under the action of a smaller preset deformation force.

[0060] In another embodiment of the present application, see Figure 7 As shown, the angle β between the first deformable connecting member 2111 and the tangent passing through the connection between one end of the first deformable connecting member 2111 and the inner periphery of the operating member 21 is a right angle or an obtuse angle, which can also enable the force-releasing deformable structure 211 to deform toward the inner periphery of the operating member 21 under the action of a smaller preset deformation force.

[0061] Along the locking direction, the latch tooth 212 is provided with a first matching slope 2121, and the slot 221 is provided with a second matching slope 22111. The first matching slope 2121 and the second matching slope 22111 cooperate with each other to facilitate the latch tooth 212 to jump over the current slot 221 when the unloading deformation structure 211 is deformed.

[0062] Along the unlocking direction, the latch tooth 212 is provided with a first mating vertical surface 2122, and the latch groove 221 is provided with a second mating vertical surface 22112. The first mating vertical surface 2122 and the second mating vertical surface 22112 cooperate with each other to ensure that the force-unloading deformation structure 211 will not be deformed, so that during the process of rotating the operating member 21 along the unlocking direction, the transmission member 23 can rotate synchronously, so that the movable part 13 can move in the direction toward the main body 11, thereby disengaging from the vehicle-mounted screen 200.

[0063] After the operating member 21 is sleeved onto the transition member 22, in order to prevent the operating member 21 from moving along its axial direction and falling off, the vehicle-mounted screen bracket provided by the present application further includes a limit assembly 25, which is arranged on the inner periphery of the operating member 21, connected to the transition member 22, and can rotate synchronously with the transition member 22. Figure 5 As shown, a stopper 24 adapted to the limiting assembly 25 is further provided on the inner periphery of the operating member 21 to limit the displacement of the operating member 21 along its axial direction.

[0064] In this embodiment, one end of the transmission member 23 is connected to the transition member 22, and the transmission member 23 is rotatably inserted into the shaft hole 112. The circumferential size of the transition member 22 is larger than the radial size of the shaft hole 112, so that the transmission member 23 can be installed in the shaft hole 112 in a non-axially movable and rotatable manner, and the external thread 231 is arranged at the other end of the transmission member 23, and a plurality of grooves 221 are arranged on the outer periphery of the transition member 22, and the aforementioned limit assembly 25 is connected to the transition member 22.

[0065] Continue to see Figure 4As shown, a mounting blind hole is provided inside the transition piece 22, and the transmission piece 23 is inserted into the mounting blind hole, and the transmission piece 23 is limited by a retaining spring 233 to prevent the transmission piece 23 from being displaced in the axial direction.

In order to improve the appearance of the product, a decorative sheet 253 is further provided above the limiting member 251.

[0067] It should be noted that the limiting member 251 abuts against the stopper 24 , and after the limiting member 251 is connected to the protrusion 232 , a certain gap may exist between the limiting member 251 and the stopper 24 , so that the limiting member 251 can rotate synchronously with the transition member 22 .

[0068] like Fig.10 and Fig.11 As shown, the body 11 is also provided with a sliding hole 113, which is coaxial with the shaft hole 112 and forms a stepped hole pile, and the body 11 is also provided with a circumferential limit groove 114, which is connected with the sliding hole 113. The movable part 13 is also provided with a column 132, wherein the inner screw hole 131 is provided on the column 132, and a circumferential limit portion 133 is further provided on the outer periphery of the column 132, so that the column 132 is slidably installed in the sliding hole 113, wherein the circumferential limit portion 133 is accommodated in the circumferential limit groove 114, so as to limit the circumference of the movable part 13.
