[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] like Figure 1 , Figure 2 As shown, a vehicle-mounted display screen rotating bracket provided by the present invention comprises: a connecting base plate 1, a mounting block 2, a hinge seat 3, a sleeve 4, a locking groove 5, a threaded cap 6, a connecting rod 7 and a clamping assembly 8; One end of the connecting substrate 1 is fixedly connected to the vehicle center console, and the other end of the connecting substrate 1 is movably connected to the mounting block 2. The mounting block 2 is connected to a hinge seat 3 on the side away from the connecting substrate 1. The hinge seat 3 is hinged to the sleeve 4. A locking groove 5 is provided on the outer peripheral surface of the top of the sleeve 4. The locking groove 5 is threadedly connected to a threaded cap 6. A connecting rod 7 is inserted in the center of the threaded cap 6, and a clamping assembly 8 is provided on the top of the connecting rod 7.

[0028] Specifically, the connecting substrate 1 is rectangular in shape and is fixed to the surface of the vehicle's center console by bolts or other fixed connection methods, serving as a connector between the vehicle-mounted display screen bracket and the vehicle; the other end of the connecting substrate 1 is movably connected to the mounting block 2, and the connection method between the two can be bonding or sliding connection. By connecting the display screen bracket to the center console area, the traditional method of directly embedding the screen is no longer used; when damage or maintenance occurs, the vehicle-mounted display screen rotating bracket and the connecting substrate 1 are directly separated, reducing the time cost of maintenance; the hinge seat 3 is a structural member used to connect two components and allow them to rotate relative to each other, including a flat end and an arc end, and the arc end is used to clamp the sleeve 4 and enable the sleeve 4 to rotate relative to the hinge seat 3, thereby enabling the user to change the tilt angle of the display screen. The elevation angle can be adjusted to a comfortable angle before use. When the display screen is tilted forward or backward relative to the user, the corresponding comfort and clarity will also be significantly improved.

[0029] A locking groove 5 is provided on the outer peripheral surface of the top of the sleeve 4, and the locking groove 5 is threadedly connected to a threaded cap 6, and a connecting rod 7 is inserted in the center of the threaded cap 6; a locking groove 5 is formed on the outer wall of the end of the sleeve 4 away from the hinge seat 3, that is, an external thread is provided on the outer wall, and a threaded cap 6 matching it is used for tightening, and a rectangular groove or a square clamping flat groove is provided on the outer wall of the threaded cap 6, which is convenient for users to directly tighten it manually. When the connecting rod 7 passes through the threaded cap 6, it extends into the hollow center of the sleeve 4 through the locking groove 5. The user rotates the connecting rod 7 left and right according to the needs of the driver's seat or the co-driver's seat, and inserts and pulls out the length of the connecting rod 7 extending out of the threaded cap 6 in the vertical direction to complete the horizontal and vertical adjustments; at this time, manually tighten the threaded cap 6. The inner wall thread of the threaded cap 6 is divided into a straight pipe thread and a tapered pipe thread. At the beginning, the straight pipe thread cooperates with the locking groove 5. As the thread matching length increases, the tapered pipe thread begins to cooperate with the thread of the outer wall of the locking groove 5. The end of the locking groove 5 is squeezed and deformed inward to fit the surface of the connecting rod 7, thereby locking the connecting rod 7 in the sleeve 4, completing the adjustment and locking of the connecting rod 7, so that the connecting rod 7 no longer shakes. A clamping assembly 8 is provided at the top of the connecting rod 7. The clamping assembly 8 directly clamps the vehicle-mounted display screen, which can adapt to screens of different sizes and has strong versatility.

[0030] As an implementation method of connecting the substrate 1 and the mounting block 2 in the present invention, Figure 1 , Figure 3 As shown, a mounting groove 101 is provided on one end surface of the connecting substrate 1 connected to the mounting block 2, protruding sliders 102 are provided on both sides of the mounting groove 101, and sliding grooves 201 capable of inserting the protruding sliders 102 are provided on both sides of the mounting block 2.

[0031] Specifically, four positioning grooves are provided at the four corners of the surface of one end of the connecting substrate 1 close to the mounting block 2, which are used to make the connecting substrate 1 fit the vehicle center console more closely. A rectangular mounting groove 101 is provided in the middle of the connecting substrate 1, and the size of the mounting groove 101 matches the mounting block 2. Raised sliding blocks 102 are provided on the left and right sides of the mounting groove 101. The raised sliding blocks 102 are protrusions with a rectangular cross-section. Correspondingly, recessed sliding grooves 201 that can match the raised sliding blocks 102 are provided on both sides of the mounting block 2, so that the mounting block 2 can slide freely in or out of the connecting substrate 1 to achieve quick disassembly and assembly.

[0032] As another embodiment of the connection between the connection substrate 1 and the mounting block 2 in the present invention, an electromagnet 9 is provided on a side of the connection substrate 1 facing away from the vehicle center console and / or on a surface of the mounting block 2 .

[0033] Specifically, Figure 4 As shown, there are three types of settings between the two: the first is that an electromagnet 9 is only provided on the surface of the mounting block 2, and a magnetic attraction sheet or iron, cobalt and other materials that can be magnetically attracted are provided on the side of the connecting substrate 1 away from the vehicle center console; the second is that an electromagnet 9 is only provided on the surface of the connecting substrate 1, and a magnetic attraction sheet is provided on the surface of the mounting block 2; the third is the optimal setting, in which electromagnets 9 that can attract each other are installed between the two, and when power is on, the adsorption is more firm to prevent the vehicle display screen from shaking, and when power is off, the connection can be quickly disconnected for easy disassembly.

[0034] In the above implementation method, the electromagnet 9 is electrically connected to a power source 901 , and the power source 901 is sequentially connected to a controller 902 and an operating terminal 903 through electrical signals. The controller 902 is used to control the electromagnet 9 to be powered on or off.

[0035] Specifically, Figure 5 As shown, when the electromagnet 9 is energized through the power supply 901, the electromagnet 9 will be tightly magnetically attracted to the magnetic sheet, and the operating end 903 includes a mobile phone or a computer. The operating end 903 and the controller 902 are wirelessly connected. The operating end 903 sends a signal, and the controller 902 receives the switch signal and controls the power supply 901 to power on or off the electromagnet 9. In addition, the tightness of the connection can be guaranteed and the device can be quickly disassembled by remote control.

[0036] In an embodiment of the present invention, the planar end of the hinge seat 3 is fixedly connected to one end of the mounting block 2, the middle part of the arc-shaped end of the hinge seat 3 clamps the sleeve 4, and the hinge seat 3 and the sleeve 4 are both provided with corresponding threaded holes, and a fastening nut 301 is connected through the threaded hole to connect the hinge seat 3 and the sleeve 4.

[0037] The sleeve 4 is hinged to the hinge seat 3 so that the inclination angle between the sleeve 4 and the mounting block 2 is 45° to 95°.

[0038] Specifically, the hinge seat 3 is a structural member used to connect two components and allow them to rotate relative to each other, including a plane end and an arcuate end, wherein the plane end can be installed on the mounting block 2 by bolts or welding, and the arcuate end of the hinge seat 3 is two parallel components, which can clamp the sleeve 4 in the middle, and an opening corresponding to the arcuate end of the hinge seat 3 is opened on the sleeve 4. After adjusting the angle between the hinge seat 3 and the sleeve 4, the fastening nut 301 is inserted from the opening so that the fastening nut 301 can fix the angle between the hinge seat 3 and the sleeve 4.

[0039] The sleeve 4 is hinged to the hinge seat 3 by tightening the nut 301 , so that the inclination angle between the sleeve 4 and the mounting block 2 is 45° to 95°, providing a comfortable viewing angle for the user.

[0040] In the embodiment of the present invention, a truncated platform 401 is provided on the outer periphery of the bottom of the sleeve 4 located at the locking groove 5 , and the truncated platform 401 is used to abut against the threaded cap 6 .

[0041] The top of the locking groove 5 is in an arc-shaped structure, and the width of the locking groove 5 gradually increases from the top to the bottom to the surface of the truncated cone 401 .

[0042] Specifically, at the top of the sleeve 4, a truncated cone 401 is provided on the outer wall below the thread of the locking groove 5. The truncated cone 401 is used to abut the threaded cap 6 that rotates downward. When the threaded cap 6 is rotated downward with force, it is very easy to squeeze the opening at the top of the locking groove 5 too large and damage the locking groove 5. However, the truncated cone 401 can avoid the above problem. Under the condition of ensuring that the locking groove 5 is not damaged, the threaded cap 6 is tightened downward to the maximum extent, so that the locking groove 5 is completely deformed inward, locking the connecting rod 7.

[0043] Specifically, the top of the locking groove 5 is a four-segment arc-shaped structure, and a vertical groove is set between two adjacent arc-shaped structures to provide a displacement position when the locking groove 5 is deformed inward and locked. The width of the locking groove 5 gradually increases from the top to the bottom to the surface of the truncated cone 401, so that when the locking groove 5 is compressed under the action of external force, the sealing between the locking groove 5 and the threaded cap 6 is guaranteed to prevent the threaded cap 6 from being unable to be locked to the bottom, causing the connecting rod 7 to loosen.

[0044] In the embodiment of the present invention, the clamping assembly 8 includes a groove 801, a lower support 802, a telescopic rod 803, a spring 804 and an upper top plate 805; A groove 801 is provided in the middle of the connecting rod 7, and an L-shaped lower support 802 is embedded in the groove 801. A telescopic rod 803 is provided at the top center of the connecting rod 7. The telescopic rod 803 achieves vertical telescopic movement by means of the elastic force of an externally sleeved spring 804. An upper top plate 805 is fixedly connected to the end of the telescopic rod 803 that is away from the connecting rod 7.

[0045] The top end of the lower support 802 and the bottom end of the upper top plate 805 are both bonded with rubber pads.

[0046] Specifically, a rectangular groove 801 is provided in the middle of the connecting rod 7, and the lower support 802 is L-shaped and inserted into the groove 801 as the lower support of the vehicle-mounted display screen, and a telescopic rod 803 is provided at the top center of the connecting rod 7, and a spring 804 is sleeved on the outside of the telescopic rod 803, one end of the spring 804 is fixed to the top of the connecting rod 7, and the other end of the spring 804 is fixed to the upper top plate 805. When the vehicle-mounted display screen needs to be inserted, the upper top plate 805 is pulled upward, and the elastic force of the spring 804 makes the telescopic rod 803 longer, so that the vehicle-mounted display screen is inserted between the upper top plate 805 and the lower support 802, forming a clamping force applied up and down. When the vehicle-mounted display screen is removed, the upper top plate 805 will move downward and retract through the elastic deformation of the spring 804. At the same time, by changing the length of the elastic deformation of the spring 804, it can adapt to vehicle-mounted display screens of different sizes, increasing versatility.

[0047] Specifically, rubber pads are bonded to the top of the lower support 802 and the bottom of the upper plate 805 to prevent long-term clamping and wear on both sides of the vehicle display screen. The rubber pads can be nitrile rubber, EPDM rubber, polytetrafluoroethylene or other wear-resistant rubber to protect both ends of the vehicle display screen.

[0048] The specific working mode of the present invention is as follows: After the connecting substrate 1 is fixedly connected to the vehicle center console, the connecting substrate 1 is connected to the mounting block 2 by sliding or electromagnetic suction, and the inclination angle of the hinge seat 3 and the sleeve 4 is adjusted to a comfortable angle, and then the angle is fixed by the fastening nut 301.

[0049] While inserting and removing the connecting rod 7 upward or downward, the connecting rod 7 is rotated left and right to meet the user's requirements for the height and left and right positions of the vehicle-mounted display screen, and then the threaded cap 6 is rotated to make the locking groove 5 retract inward and deform to fix the connecting rod 7, and the adjustment is completed. Finally, the vehicle-mounted display screen is clamped by pulling up the upper top plate 805 to complete the installation of the vehicle-mounted display screen rotating bracket.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
