[0001] This invention relates to the technical field of automobile assembly, and in particular to automobiles and screen support devices. Background Technology

[0002] Cars are now a very common means of transportation, and consumers have higher expectations and demands for their vehicles. Currently, when installing central control screens, cars often embed them directly into the center console. However, due to differences in height and build among drivers, the distance between the driver and the central control screen is often too great, making it difficult for the driver to effectively observe the screen. Sometimes, the driver needs to turn their head or lean to the side, thus affecting the driving experience. Summary of the Invention

[0025] Combination Figures 1 to 2 As shown, in one embodiment, the screen support device includes: a mounting base 100, a drive assembly 200, a transmission assembly 300, and a support assembly 400. The mounting base 100 is used to install inside the vehicle, the support assembly 400 is movably mounted on the mounting base 100, and the support assembly 400 is used to support and cooperate with the central control screen. The drive assembly 200 is in transmission cooperation with the support assembly 400 through the transmission assembly 300.

[0026] When using the aforementioned screen support device, considering the different interior structures of various automobiles, the corresponding structure or installation dimensions of the mounting base 100 are determined according to the automobile's interior structure to ensure that the mounting base 100 can be effectively installed inside the automobile. For example, the structure of the mounting base 100 is specifically designed according to the structure of the automobile's center console to achieve installation of the mounting base 100 on the center console. Furthermore, the support component 400 is movably mounted on the mounting base 100. For example, a slide rail or groove can be provided on the mounting base 100, and the support component 400 moves and engages with the mounting base 100 through the slide rail or groove. The center console screen is mounted on the support component 400. Depending on the installation requirements of the center console screen, the center console screen and the support component 400 can be fixed by clips or bolts, or a mounting plate can be added to the assembly end of the support component 400 to specifically fix the center console screen. Depending on the structure of the car's center console, the drive assembly 200 and / or transmission assembly 300 can be mounted on the center console itself, or they can be mounted on the mounting base 100. In this case, when the driver needs to view the center console screen, the driver can move the support assembly 400 on the mounting base 100 through the transmission cooperation between the drive assembly 200 and the transmission assembly 300, thereby changing the distance between the center console screen and the driver. Alternatively, the drive assembly 200 can be a motor or a roller. When the drive assembly 200 is a motor, the driver can issue commands to the drive assembly 200 to automatically move the support assembly 400. When the drive assembly 200 is a roller, the driver can directly rotate the roller to move the support assembly 400. Therefore, the aforementioned screen support device moves the support assembly 400 through the drive assembly 200 and transmission assembly 300, allowing the driver to view the center console screen more conveniently and effectively.

[0027] Combination Figure 1 and Figure 2As shown, in one embodiment, the mounting base 100 includes a fixed mounting bracket 110, a supporting mounting bracket 120, and a movable plate 130. The fixed mounting bracket 110 is used to fix and cooperate with the center console of the vehicle. One end of the supporting mounting bracket 120 is connected to one end of the fixed mounting bracket 110. The movable plate 130 is installed between the fixed mounting bracket 110 and the supporting mounting bracket 120, with one end of the movable plate 130 fixedly cooperating with the fixed mounting bracket 110 and the other end of the movable plate 130 fixedly cooperating with the supporting mounting bracket 120. The support assembly 400 is movably cooperating with the movable plate 130. Specifically, the shape and size of the fixed mounting bracket 110 are first determined according to the design shape of the vehicle's center console or the shape of the target installation part inside the vehicle, for example, to ensure that the fixed mounting bracket 110 can be fixedly fitted to the vehicle's center console. In this embodiment, one side of the fixed mounting bracket 110 can fully contact the surface of the car's center console, while bolts or screws are used to improve the fixing effect between the fixed mounting bracket 110 and the car's center console. Then, the installation length of the movable plate 130 and the movement range of the support assembly 400 on the movable plate 130 are determined according to the driver's driving habits. At the same time, after selecting the support mounting bracket 120, the fixed mounting bracket 110 and the support mounting bracket 120 are used to fix both ends of the movable plate 130, so that the movable plate 130 can be effectively fixed. Furthermore, after the movable plate 130, the fixed mounting bracket 110 and the support mounting bracket 120 are installed, the fixed mounting bracket 110 and the support mounting bracket 120 can be directly connected and fixed, that is, the movable plate 130, the fixed mounting bracket 110 and the support mounting bracket 120 form a triangle. This structure can improve the overall stability of the mounting base 100 on the one hand, and reduce the installation space of the mounting base 100 inside the car on the other hand.

[0028] Combination Figure 1 and Figure 2As shown, in one embodiment, the drive assembly 200 includes a drive motor 210 and a first mounting base 220. The first mounting base 220 is mounted on the side of the movable plate 130 opposite to the support assembly 400. The fixed mounting bracket has a first mounting opening for the passage of the first mounting base 220, and the fixed mounting bracket is fitted and fixed to the first mounting base 220. The drive motor 210 is mounted on the first mounting base 220, and one end of the transmission assembly 300 extends into the first mounting base 220 and engages with the drive motor 210 for transmission. Specifically, the drive motor 210 can be a servo motor or an AC motor. The transmission assembly 300 can be a lead screw 310 or a telescopic rod. The bidirectional rotation of the drive motor 210 drives the transmission assembly 300 to move telescopically along the target direction. The first mounting base 220 provides effective installation space for the drive motor 210, ensuring the effective use of the drive motor 210. Furthermore, when fixing the first mounting base 220, a first mounting opening is provided on the fixing mounting bracket 110, and the fixing mounting bracket 110 is fitted and fixed to the first mounting base 220. This embodiment achieves the surrounding fixation of the first mounting base 220 through the moving plate 130 and the fixing mounting bracket 110, so that the first mounting base 220 can be effectively prevented from loosening under the action of external forces (e.g., vibration caused by the operation of the drive motor 210).

[0029] In one embodiment, the drive assembly 200 includes a drive gear set and a second mounting base. The second mounting base is installed on the side of the movable plate 130 opposite to the support assembly 400. The fixed mounting bracket has a second mounting opening for the passage of the second mounting base, and the fixed mounting bracket is fitted and fixed to the second mounting base. The drive gear set is mounted on the second mounting base, and one end of the transmission assembly 300 extends into the second mounting base and engages with the drive motor 210 for transmission. Specifically, the transmission assembly 300 can be a lead screw 310 or a telescopic rod. The bidirectional rotation of the drive gear set drives the transmission assembly 300 to extend and retract along the target direction. The second mounting base provides effective installation space for the drive gear set, ensuring the effectiveness of the drive gear set. Furthermore, when fixing the second mounting base, a second mounting opening is provided on the fixed mounting bracket 110, and the fixed mounting bracket 110 is fitted and fixed to the second mounting base. The above-described embodiment achieves the enclosure and fixation of the second mounting base through the movable plate 130 and the fixed mounting bracket 110, so that the second mounting base can be effectively prevented from loosening under the action of external forces (e.g., vibration caused by the rotation of the drive gear set).

[0030] Combination Figure 1 and Figure 2As shown, in one embodiment, the transmission assembly 300 includes a transmission screw 310 and a transmission seat 320. One end of the transmission screw 310 is inserted into the first mounting seat 220 and engages with the drive motor 210. The transmission seat 320 has a threaded hole that engages with the transmission screw 310. The transmission seat 320 is movably sleeved on the outside of the movable plate 130, and the transmission seat 320 is fixedly engaged with the support assembly 400. Specifically, depending on the mounting position of the drive motor 210 on the first mounting seat 220 and the transmission direction of the drive motor 210, a transmission gear or transmission shaft can be added inside the first mounting seat 220 to ensure the transmission effect between the drive motor 210 and the transmission screw 310. When the driver needs to adjust the position of the central control screen, the operation of the drive motor 210 can be controlled by applying commands to the drive motor 210 (e.g., directly operating the drive motor 210 with buttons or setting a central control program in the central control panel to automatically control the drive motor 210). That is, the drive motor 210 drives the transmission screw 310 to rotate bidirectionally along the axial direction (the axial direction of the transmission screw 310), at which time the transmission seat 320 can drive the support assembly 400 to move forward or backward along the moving plate 130.

[0031] Combination Figure 1 and Figure 2 As shown, in one embodiment, the support assembly 400 includes an adjustment seat 410 and a screen support 420. A sliding rail is provided along the length of the movable plate 130. A groove is provided on the adjustment seat 410 to slide with the sliding rail. The screen support 420 is mounted on the adjustment seat 410 and is used to fix with the central control screen. The transmission seat 320 is fixedly engaged with the adjustment seat 410. Specifically, the number of sliding rails installed on the movable plate 130 is determined according to the installation requirements. In this embodiment, a sliding rail is added to the middle of the movable plate 130, and then a groove is added to the adjustment seat 410 to cooperate with the sliding rail. Depending on the actual sliding effect, an auxiliary wheel can also be added to the side of the adjustment seat 410 facing the movable plate 130. By having the auxiliary wheel slide with the sliding rail, the sliding effect between the adjustment seat 410 and the movable plate 130 can be changed. Furthermore, there are multiple ways to fix the screen support base and the adjustment base 410, such as: the screen support base and the adjustment base 410 are integrally formed, the screen support base and the adjustment base 410 are fixed with bolts, or the screen support base and the adjustment base 410 are fixed by snap-fit.

[0032] Combination Figure 1 and Figure 2As shown, in one embodiment, the screen support 420 further includes a rotating base 421, a screen bracket 422, and a rotating shaft. The rotating base 421 is mounted on the adjusting base 410, and the screen bracket 422 is rotatably mounted on the rotating base 421 via the rotating shaft. The screen bracket 422 is used to fix and cooperate with the central control screen. Specifically, the installation angle between the screen bracket 422 and the rotating base 421 is determined according to the installation requirements, that is, to ensure that the central control screen has a preset tilt angle after being mounted on the screen bracket 422. The screen bracket 422 can rotate relative to the rotating base 421 via the rotating shaft, thereby realizing the rotation of the central control screen.

[0033] Combination Figure 1 and Figure 2 As shown, in one embodiment, the screen support 420 further includes an adjusting wheel 423. An adjusting rail 424 is provided on the side of the rotating seat 421 along the circumference of the rotating seat 421. The adjusting wheel 423 is rotatably mounted on the screen bracket 422, and the adjusting wheel 423 rotatably engages with the adjusting rail 424. Specifically, the side shape of the rotating seat 421 can be determined according to the rotation trajectory of the screen bracket 422 on the rotating seat 421. For example, the side of the rotating seat 421 can be designed as an arc-shaped side, or the side of the rotating seat 421 can be directly designed as a rounded surface. In this case, the rotatable engagement of the adjusting wheel 423 with the side adjusting rail 424 of the rotating seat 421 makes the rotation of the screen bracket 422 and the rotating seat 421 smoother. In addition, a latch or locking pin can be added between the rotating base 421 and the screen bracket 422. When the rotating base 421 and the screen bracket 422 rotate to a preset angle, the latch or locking pin is used to position the current position of the rotating base 421 and the screen bracket 422 to prevent the rotating base 421 and the screen bracket 422 from rotating under the action of external force.

[0034] Combination Figure 1 and Figure 2 As shown, in one embodiment, the support assembly 400 further includes an auxiliary fixing plate 430, which is used to fix the central control screen cover. A first splicing block 431 is provided on the side of the auxiliary fixing plate 430 opposite to the central control screen, and a second splicing block 432 is provided on the screen bracket 422. The first splicing block 431 and the second splicing block 432 are spliced ​​and fixed together. Specifically, considering that the structure or shape of the central control screen often changes according to user needs, the screen support device can be fixed to the central control screen simply by changing the size and shape of the auxiliary fixing plate 430. Furthermore, when splicing and fixing the first splicing block 431 and the second splicing block 432, clips or bolts can also be used for auxiliary fixing.

[0035] In one embodiment, an automobile includes the aforementioned screen support device, and further includes an automobile body and a central control screen, wherein the screen support device is installed inside the automobile body and the central control screen is installed on the screen support device.

[0036] During the assembly of the aforementioned vehicle, the screen support device is mounted on the vehicle body. The central control screen is mounted on the support component 400. Depending on the installation requirements of the central control screen, the central control screen and the support component 400 can be fixed by clips or bolts, or a mounting plate can be added to the mounting end of the support component 400 to specifically fix the central control screen. Depending on the internal structure of the vehicle body, the drive component 200 and / or transmission component 300 can be mounted on the vehicle body, or the drive component 200 and / or transmission component 300 can be mounted on the mounting base 100. In this case, when the driver needs to view the central control screen while driving the vehicle, the driver can move the support component 400 on the mounting base 100 through the transmission cooperation between the drive component 200 and the transmission component 300, thereby changing the distance between the central control screen and the driver. In addition, the drive component 200 can be a motor or a roller. When the drive component 200 is a motor, the driver can issue commands to the drive component 200 to drive the support component 400 to move automatically. When the drive component 200 is a roller, the driver can directly rotate the roller to move the support component 400. Therefore, the screen support device described above drives the support component 400 to move through the drive component 200 and the transmission component 300, thereby enabling the driver to view the central control screen more conveniently and effectively.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
