[0048] The present invention will be described in more detail below in conjunction with the accompanying drawings. It should be noted that the description of the present invention with reference to the accompanying drawings is only illustrative and not restrictive. The various embodiments can be combined with each other to form other embodiments not shown in the following description.

[0049] See also Figure 1 and Figure 2 In one embodiment of the present invention, a new screen bracket mechanism 100 is provided. The screen bracket mechanism 100 can be installed on a seat 200 of a vehicle, has a simple structure, and has good applicability.

[0050] The screen bracket mechanism 100 includes: a lock screen bracket 10, an adapter bracket 20, a fixed box body 30 and a locking mechanism 40. The lock screen bracket 10 is used to clamp large screens, computers and other entertainment equipment; the adapter bracket 20 is hinged to the lock screen bracket 10, and the user can adjust the angle of the lock screen bracket 10 by flipping it, so that the user can adjust the angle of the lock screen bracket 10 according to the viewing angle; the fixed box body 30 is fixedly mounted on the seat 200, and the adapter bracket 20 can be slidably inserted into the fixed box body 30; the locking mechanism 40 is connected to the adapter bracket 20, and the locking mechanism 40 can lock or unlock the adapter bracket 20 in the fixed box body 30.

[0051] It can be understood that when the adapter bracket 20 is inserted into the fixed box body 30, the locking mechanism 40 can lock the adapter bracket 20 in the fixed box body 30; when the adapter bracket 20 needs to be taken out, the locking mechanism 40 is unlocked so that the adapter bracket 20 can be taken out of the fixed box body 30, thereby realizing a detachable connection between the adapter bracket 20 and the fixed box body 30.

[0052] Please also refer to Figures 3 to 6 The lock screen bracket 10 includes: a first shell 11, a first claw 12, a second claw 13 and a third claw 14.

[0053] The first shell 11 and the adapter bracket 20 are hingedly matched, that is, the side of the first shell 11 facing the adapter bracket 20 is hinged to the adapter bracket 20; one end of the first claw 12 is laterally inserted into the first shell 11, and the first claw 12 can move laterally relative to the first shell 11; one end of the second claw 13 is laterally inserted into the first shell 11, and the second claw 13 can move laterally relative to the first shell 11, and the first claw 12 and the second claw 13 are respectively arranged on opposite sides of the first shell 11; one end of the third claw 14 is longitudinally inserted into the first shell 11, and can move longitudinally relative to the first shell 11.

[0054] Understandable, such as Figure 3 As shown, the first claw 12 and the second claw 13 are located on the left and right sides of the first shell 11 to laterally clamp the large screen, computer and other entertainment equipment installed on the lock screen bracket 10; the third claw 14 is located below the first shell 11 to longitudinally clamp the large screen, computer and other entertainment equipment installed on the lock screen bracket 10 to prevent the large screen, computer and other equipment installed on the lock screen bracket 10 from shaking.

[0055] Among them, a first rod shaft 111 is formed axially in the first shell 11, and the first rod shaft 111 is located on the side of the first shell 11 that is away from the adapter bracket 20; a gear 112 is sleeved on the circumferential outer side of the first rod shaft 111, and the gear 112 can rotate around the first rod shaft 111. The first claw 12, the second claw 13 and the third claw 14 are all engaged with the gear 112. When the third claw 14 moves longitudinally, it drives the gear 112 to rotate, and then the gear 112 drives the first claw 12 and the second claw 13 to move laterally.

[0056] Among them, Figure 4 and Figure 5 As shown, the end of the first claw 12 that penetrates into the first shell 11 is provided with a first groove 121, and the edge of the first groove 121 is formed with a first serrated segment 122 along the horizontal direction. The first serrated segment 122 is meshed with the gear 112. When the gear 112 rotates clockwise, it can drive the first serrated segment 122 to move horizontally to the right; when the gear 112 rotates counterclockwise, it can drive the first serrated segment 122 to move horizontally to the left.

[0057] In addition, a first limiting column 114 is formed in the first housing 11 along the axial direction, and a first guide opening 123 is opened in the first claw 12 along the lateral direction. The first limiting column 114 is inserted into the first guide opening 123, so that the moving direction of the first claw 12 is limited by the cooperation between the first limiting column 114 and the first guide opening 123. Figure 4 shown.

[0058] Among them, Figure 4 and Figure 5 As shown, the end of the second claw 13 that penetrates into the first shell 11 is provided with a second groove 131, and the edge of the second groove 131 is formed with a second sawtooth segment 132 along the horizontal direction. The second sawtooth segment 132 is meshed with the gear 112, and the first sawtooth segment 122 and the second sawtooth segment 132 are symmetrically arranged on both sides of the gear 112; when the gear 112 rotates clockwise, it can drive the second sawtooth segment 132 to move horizontally to the left; when the gear 112 rotates counterclockwise, it can drive the second sawtooth segment 132 to move horizontally to the right.

[0059] In addition, a second limiting column 115 is formed in the first housing 11 along the axial direction, and a second guide opening 133 is opened in the second claw 13 along the lateral direction. The second limiting column 115 is inserted into the second guide opening 133, so as to limit the moving direction of the second claw 13 based on the cooperation between the second limiting column 115 and the second guide opening 133. Figure 4 shown.

[0060] Among them, Figure 4 and Figure 5 As shown, a first opening 141 is provided at a port through which the third clamping claw 14 penetrates into the first shell 11, and a third serrated segment 142 is formed on the edge of the first opening 141 along the longitudinal direction. The third serrated segment 142 is meshed with the gear 112, and the gear 112 is always penetrated in the first opening 141; when the third clamping claw 14 is longitudinally moved by an external force, the gear 112 can be driven to rotate clockwise or counterclockwise through the third serrated segment 142.

[0061] In order to further prevent the large screen, computer and other devices installed on the lock screen bracket 10 from shaking, a tightening mechanism 113 is also installed on the lock screen bracket 10 for tightening the large screen, computer and other devices. A first cover plate 15 is connected to the first shell 11, and the first cover plate 15 is located on the side of the first shell 11 facing away from the adapter bracket 20; a first limiting groove 151 is formed on the side of the first cover plate 15 facing the first shell 11, and the tightening mechanism 113 is installed in the first limiting groove 151.

[0062] It can be understood that the number of the first limiting grooves 151 formed on the first cover plate 15 can be one or more, and the number of the pressing mechanisms 113 is the same as the number of the first limiting grooves 151 .

[0063] Among them, Figure 6 As shown, the pressing mechanism 113 includes: a first rotating shaft 1131, a pressing member 1132 and a first torsion spring 1133. The first rotating shaft 1131 is inserted into the first limiting groove 151. One end of the pressing member 1132 is rotatably sleeved on the circumferential outer side of the first rotating shaft. The other end of the pressing member 1132 is formed with a first convex portion 1134. The first convex portion 1134 passes through the first cover plate 15. Figure 3 As shown, the first torsion spring 1133 is sleeved on the circumferential outer side of the first rotating shaft 1131, and the two ends of the first torsion spring 1133 are respectively inserted on the two opposite side walls of the first limiting groove 151, and the two ends of the first torsion spring 1133 are also respectively in contact with the pressing member 1132. When the large screen, computer and other equipment are inserted into the side of the first cover plate 15 facing away from the first shell 11, the first protrusion 1134 is forced to move toward the first shell 11, and drives the pressing member 1132 to rotate relative to the first rotating shaft 1131, so that the first torsion spring 1133 is in a compressed state. At this time, the elastic force formed by the compression of the first torsion spring 1133 presses the pressing member 1132, and then the first protrusion 1134 presses against the large screen, computer and other equipment.

[0064] It can be understood that, taking the installation of a large screen on the lock screen bracket 10 as an example, the working process of the lock screen bracket 10 is:

[0065] The user inserts the large screen from top to bottom along the side of the first cover plate 15 and presses against the third claw 14, and the third claw 14 moves downward. At this time, the third serrated segment 142 moves downward and drives the gear 112 to rotate clockwise; then, the gear 112 drives the first serrated segment 122 to move laterally to the right, so that the first claw 12 moves laterally to the right and clamps the large screen; the gear 112 drives the second serrated segment 132 to move laterally to the left, so that the second claw 13 moves to the left and clamps the large screen; in addition, in the process of the large screen passing through the first cover plate 15, the large screen and the first protrusion 1134 are in a tight state.

[0066] Please also refer to Figure 7 and Figure 8 The adapter bracket 20 and the lock screen bracket 10 are hinged by a hinge mechanism 50. The hinge mechanism 50 includes: a first hinge 51, a second hinge 52 and a hinge shaft 53. One end of the first hinge 51 is connected to the adapter bracket 20, and the hinge shaft 53 is arranged on the other end of the first hinge 51; one end of the second hinge 52 is sleeved on the circumferential outer side of the hinge shaft 53 and can rotate around the hinge shaft 53; the other end of the second hinge 52 is connected to the lock screen bracket 10, so that the lock screen bracket 10 can rotate relative to the adapter bracket 20 around the hinge shaft 53.

[0067] In addition, the adapter bracket 20 includes: a second shell 21 and an electrical component 22. The electrical component 22 can be used to supply power or communicate with devices such as a large screen and a computer installed on the lock screen bracket 10, and an electrical connector 23 for power supply and communication is connected between the electrical component 22 and the first shell 11; the electrical component 22 is fixedly installed in the second shell 21, and the first hinge 51 is fixedly connected to the end of the electrical component 22 close to the first shell 11.

[0068] Please also refer to Figures 9 to 11 The fixed box body 30 is provided with an installation opening 32 and a flip opening 36, and the adapter bracket 20 can be inserted into the installation opening 32; a second cover plate 33 for covering the installation opening 32 is installed on the fixed box body 30, and the second cover plate 33 can rotate relative to the fixed box body 30, that is, the second cover plate 33 can be flipped from the installation opening 32 to the flip opening 36. Specifically, as Fig. 9 As shown, a second rotating shaft 34 is transversely mounted above the fixed box body 30, and a bent portion 331 is formed at both transverse ends of the second cover plate 33, and one end of the bent portion 331 is sleeved on the circumferential outer side of the second rotating shaft 34. In addition, a fourth torsion spring 35 is sleeved on the end of the second rotating shaft 34, and both ends of the fourth torsion spring 35 are respectively abutted on the fixed box body 30 and the second cover plate 33.

[0069] It can be understood that in the initial state, the second cover plate 33 is located at the installation opening 32, and the fourth torsion spring 35 is not compressed. Fig.10 When the adapter bracket 20 is inserted into the mounting opening 32, the second cover plate 33 is flipped to the flip opening 36, and the fourth torsion spring 35 is compressed and deformed by force, as shown Fig. 9 When the adapter bracket 20 is taken out from the mounting opening 32 , the second cover plate 33 gradually flips toward the mounting opening 32 under the pressure of the fourth torsion spring 35 .

[0070] In addition, if Fig.11 As shown, a locking groove 31 is formed on the side of the fixed box body 30 facing the locking mechanism 40 , and the locking mechanism 40 can be snapped into the locking groove 31 to lock the adapter bracket 20 on the fixed box body 30 .

[0071] Please also refer to Figure 12 to Figure 14 The locking mechanism 40 includes: a locking tongue member 41 and an unlocking member 42. The locking tongue member 41 is rotatably connected to the adapter bracket 20, and the locking tongue member 41 can be snap-fitted with the locking groove 31 to lock the adapter bracket 20 in the fixed box body 30; the unlocking member 42 is slidably arranged on the second shell body 21, one end of the unlocking member 42 faces the lock screen bracket 10, and the other end is pressed against the locking tongue member 41. When the unlocking member 42 slides toward the lock screen bracket 10, the unlocking member 42 presses the locking tongue member 41 to make the locking tongue member 41 disengage from the locking groove 31, thereby facilitating the user to take the adapter bracket 20 out of the fixed box body 30.

[0072] In order to facilitate the user to pull the unlocking member 42 to unlock, a second opening 422 is opened at one end of the unlocking member 42 close to the lock screen bracket 10, and the user can drive the unlocking member 42 to slide through the second opening 422.

[0073] Among them, the locking tongue member 41 includes: a first locking tongue portion 411, a butt portion 412 and a second locking tongue portion 413. The first locking tongue portion 411 and the second locking tongue portion 413 are symmetrically arranged at both ends of the butt portion 412. The first locking tongue portion 411 and the second locking tongue portion 413 can be snapped into the corresponding locking groove 31 to lock the adapter bracket 20; the butt portion 412 is pressed and matched with the unlocking member 42. When the unlocking member 42 slides toward the direction of the lock screen bracket 10, the unlocking member 42 presses the butt portion 412 to make the first locking tongue portion 411 and the second locking tongue portion 413 disengage from the locking groove 31.

[0074] Among them, an unlocking portion 421 is formed at one end of the unlocking piece 42 close to the abutting portion 412, and a second inclined surface 4211 is formed on the side of the unlocking portion 421 facing the abutting portion 412; a first inclined surface 4121 is formed on the side of the abutting portion 412 facing the unlocking portion 421, and the first inclined surface 4121 and the second inclined surface 4211 are pressed and matched, so that when the unlocking portion 421 slides toward the direction of the lock screen bracket 10, the second inclined surface 4211 can slide along the first inclined surface 4121; at the same time, since the unlocking piece 42 cannot move toward or away from the locking groove 31, when the second inclined surface 4211 gradually presses against the first inclined surface 4121, the locking tongue piece 41 will gradually disengage from the locking groove 31, so that the adapter bracket 20 and the fixed box body 30 are in an unlocked state.

[0075] Among them, a mounting groove 24 is formed on the side of the second shell 21 facing the locking groove 31, and the locking tongue member 41 is rotatably installed in the mounting groove 24. At the same time, a first shaft member 25 is extended to form at the groove wall of the mounting groove 24 facing the first locking tongue portion 411, and the axial direction of the first shaft member 25 is perpendicular to the length direction of the first locking tongue portion 411; a first abutting portion 4111 is formed on the side of the first locking tongue portion 411 facing the first shaft member 25, and the first abutting portion 4111 is parallel and spaced from the first shaft member 25. A second torsion spring 251 is sleeved on the first shaft member 25, one end of the second torsion spring 251 abuts against the second shell body 21, and the other end abuts against the first abutting portion 4111. When the first locking tongue portion 411 is engaged with the locking groove 31, the second torsion spring 251 is in an uncompressed state; in the process that the first locking tongue portion 411 gradually disengages from the locking groove 31, the second torsion spring 251 is gradually compressed by force. If the unlocking portion 421 disengages from the abutting portion 412, the first locking tongue portion 411 can rotate in a direction away from the second shell body 21 under the action of the elastic force formed by the compression deformation of the second torsion spring 251.

[0076] A second shaft 26 is formed extending from the groove wall of the installation groove 24 facing the second locking tongue portion 413, and the axial direction of the second shaft 26 is perpendicular to the length direction of the second locking tongue portion 413; a second abutting portion 4131 is formed on the side of the second locking tongue portion 413 facing the second shaft 26, and the second abutting portion 4131 is parallel and spaced from the second shaft 26. A third torsion spring 261 is sleeved on the second shaft 26, one end of the third torsion spring 261 abuts on the second housing 21, and the other end abuts on the second abutting portion 4131. When the second locking tongue portion 413 is abutted with the locking groove 31, the third torsion spring 261 is in an uncompressed state; when the second locking tongue portion 413 gradually disengages from the locking groove 31, the third torsion spring 261 is gradually compressed by force, and when the unlocking portion 421 disengages from the abutting portion 412, the second locking tongue portion 413 can rotate in a direction away from the second housing 21 based on the elastic force formed by the compression deformation of the third torsion spring 261.

[0077] Among them, a first pillar 4212 is extended and formed on one side of the unlocking portion 421 facing away from the bottom of the installation groove 24, and a second pillar 211 is formed on the second housing 21. The second pillar 211 is spaced apart from the first pillar 4212, and the first pillar 4212 and the second pillar 211 are respectively connected to the two ends of the same return spring 4213, so that the unlocking member 42 can be automatically reset based on the elastic action of the return spring 4213. It can be understood that the deformation direction of the return spring 4213 is the same as the moving direction of the unlocking member 42.

[0078] The locking and unlocking process between the adapter bracket 20 and the fixed box body 30 provided in the above embodiment can be described in detail as follows:

[0079] When the user inserts the adapter bracket 20 into the installation opening 32, the locking tongue member 41 always compresses the second torsion spring 251 and the third torsion spring 261 until the locking tongue member 41 slides to a position exactly opposite to the locking groove 31. The locking tongue member 41 rotates toward the direction of the locking groove 31 and is in a clamping state with the locking groove 31 under the elastic force formed by the compression deformation of the second torsion spring 251 and the third torsion spring 261, thereby locking the adapter bracket 20 on the fixed box body 30.
