[0010] The push rod part is fixedly connected to the screen, and is provided with a guide groove slidably connected to the guide slide, and is also provided with a guide column slidably connected to the bidirectional groove and the give-way groove and located in the extending direction of the guide groove;

[0011] A driving motor is used to drive the actuator to rotate clockwise or counterclockwise;

[0012] The bidirectional groove is specifically configured as a V-shaped groove and is symmetrical about the plane where the central axis of the guide slide and the rotation axis of the actuator are located.

[0013] The utility model has at least the following beneficial effects:

[0014] The tilt direction and tilt angle of the screen can be controlled only by driving the actuator to rotate with a driving motor. It has a simple structure and low manufacturing cost. It can also achieve synchronous extension and retraction of the screen while controlling the rotation of the screen, thereby avoiding interference with the surrounding environment caused by the screen rotating in place, greatly improving the overall working reliability of the device and its compatibility with the car dashboard.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] The following is a detailed description of the vehicle-mounted screen driving device provided in the embodiment of the present application through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0029] like Figures 1 to 9 As shown, an embodiment of the present application provides a vehicle-mounted screen driving device, including a mounting shell 110, a fixing frame 150 fixedly disposed on the mounting shell 110, an actuator 160 rotatably disposed on the fixing frame 150, a push rod portion 120 fixedly connected to the screen 200, and a driving motor 130 for driving the actuator 160 to rotate.

[0030] A guide groove 121 is provided on the push rod part 120, a guide slide 192 slidably connected to the guide groove 121 is fixedly provided on the fixed frame 150, a bidirectional groove 151 is provided on the fixed frame 150, a yield groove 161 extending radially along the rotation axis of the actuator 160 is provided on the actuator 160, and a guide column 171 slidably connected to the bidirectional groove 151 and the yield groove 161 and located in the extension direction of the guide groove 121 is fixedly provided on the push rod part 120.

[0031] The bidirectional groove 151 is specifically configured as a V-shaped groove and is symmetrical about the plane where the central axis of the guide slide 192 and the rotation axis of the actuator 160 are located.

[0032] Initially, the guide post 171 is located at the center position of the two-way groove 151. When the driving motor 130 drives the actuator 160 to rotate forward or reverse, the groove wall of the give way groove 161 can contact the guide post 171, so that the guide post 171 slides in the two-way groove 151 along the corresponding direction. Under the guiding action of the two-way groove 151 on the guide post 171, the push rod part 120 moves relative to the mounting shell 110 to achieve posture control of the screen 200, the guide slide 192 slides in the guide groove 121, and the guide post 171 slides in the give way groove 161 to achieve matching of the relative positions of the push rod part 120 and the actuator 160.

[0033] It can be understood that when the guide column 171 moves along one side of the groove wall in the two-way groove 151, it can drive the push rod portion 120 to move away from or closer to the actuator 160 relative to the mounting shell 110, thereby realizing the telescopic control of the screen 200. At the same time, through the change in the angle between the connecting line of the guide slide 192, the guide column 171 and the symmetry plane of the two-way groove 151, the rotation and tilt angle of the screen 200 can be controlled.

[0034] In an embodiment of the present application, the above-mentioned vehicle-mounted screen driving device is adopted, and the tilt direction and tilt angle of the screen 200 can be controlled only by driving the actuator 160 to rotate through the driving motor 130. The structure is simple and the manufacturing cost is low. At the same time, while controlling the rotation of the screen 200, the screen 200 can also be synchronously extended and retracted, thereby avoiding interference with the surrounding environment caused by the screen 200 rotating in place, greatly improving the overall working reliability of the device and its compatibility with the car dashboard.

[0035] In a preferred embodiment, Figure 2 As shown, the mounting housing 110 includes a base 111 and a top cover 112 , and the base 111 and the top cover 112 are buckled to form a receiving cavity for receiving the push rod portion 120 .

[0036] The driving motor 130 and the fixing frame 150 are fixedly disposed on the inner wall of the accommodating cavity.

[0037] In a preferred embodiment, an embedding groove for accommodating the driving motor is provided on the inner wall of the accommodating cavity.

[0038] In a preferred embodiment, Figure 2 As shown, the driving motor 130 and the actuator 160 are respectively located on both sides of the fixing frame 150 , and a connecting member 140 is fixedly provided on the power output end of the driving motor 130 . The connecting member 140 passes through the fixing frame 150 and is rotatably connected to the fixing frame 150 . The actuator 160 is fixedly provided on the connecting member 140 .

[0039] It can be understood that, by setting the relative positions of the driving motor 130 , the fixing bracket 150 , and the actuator 160 , the overall compactness of the device can be improved, which facilitates the miniaturization design of the device.

[0040] In a preferred embodiment, Figures 2 to 4 As shown, a through hole 152 is formed on the fixing frame 150 , a mounting hole 162 is formed on the actuator 160 , and the connecting member 140 passes through the through hole 152 and is fixedly connected to the actuator 160 via the mounting hole 162 .

[0041] In a preferred embodiment, Figure 2 , Figure 5 As shown, a limiting bolt 172 is rotatably provided on the push rod portion 120 . The limiting bolt 172 penetrates the push rod portion 120 from a side of the push rod portion 120 away from the fixing frame 150 and is threadedly connected to the guide column 171 .

[0042] It is understandable that the fixing connection method of the guide column 171 on the push rod part 120 is not limited to the above-mentioned one. For example, the guide column 171 can be configured to be integrally formed with the push rod part 120, or the two can be connected by welding, clamping, etc. As long as the guide column 171 can be fixed on the push rod part 120, it will not be elaborated here.

[0043] In a preferred embodiment, Figure 2 , Figure 5 As shown, the guide groove 121 is set through the push rod part 120, the guide slide 192 passes through the guide groove 121 and is fixed with a limit ring 191 located on the side of the push rod part 120 away from the fixing frame 150, and the limit ring 191 can abut the end face of the push rod part 120 away from the fixing frame 150.

[0044] It is understandable that the displacement of the push rod part 120 away from the fixing frame 150 can be limited by the limit ring 191, thereby preventing the push rod part 120 from tilting due to vehicle shaking or force on the screen 200, thereby ensuring the position stability of the screen 200.

[0045] It is understandable that the limit ring 191 is detachably connected to the guide slide 192 , for example, the limit ring 191 can be threadedly connected to the guide slide 192 , thereby facilitating the installation and removal of the push rod part 120 on the guide slide 192 .

[0046] In a preferred embodiment, Figure 2 , Figure 6 As shown, it also includes a yield bracket 180 fixedly arranged on the end surface of the fixing frame 150 away from the push rod part 120 , and the connecting member 140 passes through the yield bracket 180 and the fixing frame 150 and is fixedly connected to the actuator 160 .

[0047] It can be understood that the clearance bracket 180 can increase the clearance space of the fixing frame 150 away from the push rod part 120. When the guide column 171 slides in the two-way groove 151, it can avoid interference between the guide column 171 and the inner wall of the accommodating cavity of the driving motor 130 or the mounting shell 110, thereby improving the working stability of the device.

[0048] In a preferred embodiment, Figure 2 , Figure 3 , Figure 5 , Figures 7 to 9 As shown, the bidirectional groove 151 is located on the side of the rotation axis of the actuator 160 away from the guide slide 192 and the opening faces the guide slide 192 .

[0049] Initially, if Figure 7 As shown, the guide column 171 is located at one end of the clearance groove 161 away from the rotation axis of the clearance groove 161 and the center of the bidirectional groove 151, and the guide slide 192 is located at one end of the guide groove 121 away from the actuator 160;

[0050] When adjusting, Figure 8 As shown, the driving motor 130 drives the actuator 160 to rotate forward or reversely. When the actuator 160 rotates, the guide post 171 moves in the yielding groove 161 based on the relative position with the push rod part 120, and moves in one side groove of the two-way groove 151 toward the side close to the guide slide 192. The guide slide 192 moves in the guide groove 121 relative to the push rod part 120 toward the side close to the actuator 160. At this time, under the change of the relative angle between the connecting line between the guide post 171 and the guide slide 192 and the symmetry plane of the two-way groove 151, the push rod part 120 drives the screen 200 to rotate and tilt toward the corresponding side, and at the same time, the push rod part 120 extends toward the side away from the actuator 160, thereby driving the screen 200 to extend in the tilting direction;

[0051] When the angle of the screen 200 is adjusted to the limit position, as shown in FIG. Fig. 9 As shown, the guide post 171 is located at one end of the give way groove 161 away from the rotation axis of the give way groove 161 and the end position in one of the two-way grooves 151, and the guide slide 192 is located at one end of the guide groove 121 close to the actuator 160, that is, the actuator 160 and the push rod part 120 are limited by the interference between the guide slide 192 and the guide groove 121 and between the guide post 171 and the two-way groove 151, thereby realizing the maximum rotation angle limit of the screen 200;

[0052] It is understandable that the device can be driven to reset along the above-mentioned route by the reverse rotation of the driving motor 130, which will not be elaborated here.

[0053] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.
