DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] See attached Figure 1 -Attached Figure 6 A screen adjustment base includes a shell 1 and a driving mechanism 2; a rotating shaft 10 for connecting a screen is rotatably mounted on the shell 1, and a linkage block 101 with a guide groove 102 is provided on the rotating shaft 10; the driving mechanism 2 includes a slider 21, a screw rod 22 and a driving member 23, the slider 21 is slidably mounted in the shell 1 and is provided with a guide column 210 that slides with the guide groove 102, the screw rod 22 is rotatably mounted in the shell 1 and is threadedly connected to the screw rod 22, and the driving member 23 is mounted in the shell 1 and is drivingly connected to the screw rod 22.
[0035] Specifically, when in use, the driving mechanism 2 drives the screw 22 to rotate, thereby driving the slider 21 to move, and then the guide column 210 drives the shaft 10 to rotate, so as to adjust the rotation angle of the screen; compared with the prior art, the screen adjustment base integrates the shaft 10 and the driving mechanism 2 in the shell 1, so that the structure is compact and the installation space required is small. The method of driving the slider 21 by the screw 22 can improve the movement accuracy of the slider 21, so as to accurately adjust the rotation angle of the screen and improve the user experience.
[0036] See attached Figure 1 -Attached Figure 6 The driving member 23 includes a motor 231 and a gear set 232 . The output shaft of the motor 231 is drivingly connected to the input end of the gear set 232 , and the output end of the gear set 232 is drivingly connected to the screw rod 22 .
[0037] Specifically, when in use, the motor 231 is started to drive the gear set 232, and the gear set 232 drives the screw 22 to rotate, thereby driving the slider 21 to move; wherein, the design of the gear set 232 can slow down the rotation speed of the motor 231 driving the screw 22 to improve the rotation stability of the screw 22.
[0038] See attached Figure 1 -Attached Figure 6The gear set 232 includes a main gear 2320, a first gear 2321, a second gear 2322 and a sub-gear 2323. The main gear 2320 is mounted on the output shaft of the motor 231. The first gear 2321 and the second gear 2322 are both rotatably connected to the housing 1, and the first gear 2321 is meshedly connected to the main gear 2320 and the second gear 2322. The sub-gear 2323 is coaxially mounted on the screw 22 and meshedly connected to the second gear 2322.
[0039] Specifically, the motor 231 drives the main gear 2320 to rotate, and then drives the first gear 2321, the second gear 2322 and the sub-gear 2323 in sequence to rotate the screw 22; the use of multiple gears in combination can slow down the rotation speed of the motor 231 driving the screw 22 to improve the rotation stability of the screw 22.
[0040] See attached Figure 5 -Attached Figure 7 The utility model further includes a monitoring component 3 , which is installed in the housing 1 and electrically connected to the motor 231 for monitoring and controlling the moving distance of the slider 21 .
[0041] Specifically, during use, the monitoring component 3 monitors the movement distance of the slider 21 in real time according to a preset input program. When the monitored movement distance corresponds to the preset angle that needs to be adjusted, the monitoring component 3 sends a command to the motor 231, and the motor 231 controls the screw 22 to stop according to the feedback information, so that the slider 21 can accurately stop at the current position.
[0042] See attached Figure 5 -Attached Figure 7 The monitoring component 3 includes a control board (not shown) and a sliding displacement sensor 31. The control board is installed in the housing 1 and is electrically connected to the motor 231 and the sliding displacement sensor 31. The sliding displacement sensor 31 is installed under the slider 21, and a test block 310 is slidably installed on the sliding displacement sensor 31, and the test block 310 is connected to the slider 21.
[0043] Specifically, during use, the user can input specific rotation angle information on a screen (not shown) or other devices, and the screen or other devices transmit the information to the control panel, and the control panel controls the motor 231 to start and drive the slider 21 to move; during this process, the slider 21 will drive the test block 310 to move on the sliding displacement sensor 31, so that the sliding displacement sensor 31 can obtain the specific movement distance information of the slider 21. When the obtained movement distance information corresponds to the input rotation angle information, the motor 231 is controlled to stop, so that the slider 21 stops.
[0044] It should be noted that the control panel and the sliding displacement sensor 31 are both existing products, and the technology of presetting the program for the control panel through the screen, and monitoring the slider 21 and controlling the start and stop timing of the motor 231 through the sliding displacement sensor 31 and the control panel are relatively conventional in this technical field, so the specific working principle and circuit structure are not further elaborated in the utility model.
[0045] See attached Figure 6 -Attached Figure 8 The slider 21 and the test block 310 can be connected by bonding, clamping, threading, etc., which are not listed one by one in the utility model. For the sake of easy understanding, in this embodiment, the slider 21 is provided with a slot 2100, and the test block 310 is provided with a column 3100 that is plugged into the slot 2100. This connection method facilitates the connection and disassembly between the slider 21 and the sliding displacement sensor 31.
[0046] See attached Figure 6 -Attached Fig.10 Since the slider 21 and the screw rod 22 are threadedly connected, after long-term use, the connecting threads between the slider 21 and the screw rod 22 are prone to wear and tear to produce gaps, resulting in a decrease in the movement accuracy of the slider 21. To solve this problem, the utility model also includes an elastic member 4 and a sleeve 5. The slider 21 is provided with a shaft cylinder 211 threadedly connected to the screw rod 22, and the shaft cylinder 211 is provided with a limit opening 212; the sleeve 5 is threadedly connected to the screw rod 22, and a limit block 52 and a stopper 51 are respectively provided at both ends of the sleeve 5, and the limit block 52 can be inserted into the limit opening 212; the elastic member 4 is sleeved on the sleeve 5 and the shaft cylinder 211, and the two ends of the elastic member 4 are respectively against the stopper 51 and the slider 21.
[0047] Specifically, during assembly, the elastic member 4 is first sleeved on the shaft sleeve 5 and the shaft cylinder 211, and the limit block 52 on the shaft sleeve 5 is placed in the limit opening 212, so that the shaft sleeve 5 is coaxially aligned with the shaft cylinder 211. At this time, the shaft cylinder 211 can limit the rotation of the shaft sleeve 5, but cannot limit the movement of the shaft sleeve 5. Therefore, when the shaft sleeve 5 approaches the shaft cylinder 211 in the straight direction, the stop block 51 squeezes the elastic member 4 to apply pressure to the slider 21; after determining the distance between the shaft sleeve 5 and the shaft cylinder 211 in the straight direction, the screw 22 is used to pass through the slider 21, the shaft cylinder 211 and the shaft sleeve 5, so that the relative distance between the shaft sleeve 5 and the shaft cylinder 211 is fixed.
[0048] During the movement of the slider 21, the elastic member 4 is deformed under the extrusion of the sleeve 5. After the deformation, the elastic member 4 has a recovery tendency to continuously apply pressure to the slider 21, thereby eliminating the thread gap between the slider 21 and the screw 22, ensuring the movement accuracy of the slider 21 and the rotation accuracy of the screen; and the cooperation between the limit block 52 and the limit opening 212 can limit the rotation of the sleeve 5, to prevent the screw 22 from driving the sleeve 5 away from the slider 21 when rotating, causing the elastic member 4 to return to its original state, to ensure that the elastic member 4 can continuously apply pressure to the slider 21.
[0049] See attached Figure 8 -Attached Fig.10 The elastic member 4 can be made of rubber columns, elastic plastic sleeves, springs and other accessories. For ease of understanding, the elastic member 4 is taken as an example of a spring in this embodiment; the spring has the advantages of low cost, good elasticity, good deformation ability and recovery ability, and long service life.
[0050] See attached Figure 3 -Attached Figure 6 A first bearing 10z is provided at the rotation connection between the rotating shaft 10 and the housing 1, and a second bearing 22z is provided at the rotation connection between the screw rod 22 and the housing 1.
[0051] Specifically, the design of the first bearing 10z can be used to support the rotating shaft 10 and reduce the friction between the rotating shaft 10 and the housing 1, so as to improve the installation stability of the rotating shaft 10 and reduce the wear of the rotating shaft 10; the design of the second bearing 22z can be used to support the screw 22 and reduce the friction between the screw 22 and the housing 1, so as to improve the installation stability of the screw 22 and reduce the wear of the screw 22.
[0052] See attached Figure 1 -Attached Figure 6 The shell 1 includes a base shell 11 and a cover plate 12. The base shell 11 is provided with a receiving chamber 110 which is open outward. The cover plate 12 is detachably mounted on the base shell 11 to close or open the receiving chamber 110. The cover plate 12 is provided with a rotating hole 111 which connects the receiving chamber 110 with the outside. The rotating shaft 10 is rotatably matched with the rotating hole 111, and the linkage block 101 is placed in the receiving chamber 110. The driving mechanism 2 is installed in the receiving chamber 110. The matching design of the base shell 11 and the cover plate 12 facilitates the production and assembly of the shell 1, and also facilitates the installation and maintenance of the driving mechanism 2 and the rotating shaft 10.
[0053] See attached Figure 1 -Attached Figure 6 The base shell 11 is provided with a mounting hole 112 for inserting a bolt; the screen adjustment base can be fixed on the center console by connecting the center console of the car (not shown) through the bolt passing through the mounting hole 112.
[0054] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
