Description

Technical Field

[0001] The utility model relates to the technical field of screen flipping, in particular to a screen flipping motion device. Background Art

[0002] At present, the sub-dashboard designs of most cars on the market have integrated practical functions such as cup holders and wireless charging, but these designs are often limited to basic storage and charging needs and lack direct operational support for the core functions of the vehicle (such as air conditioning control and multimedia entertainment).

[0003] To solve the above problems, car manufacturers have added a small control screen to the sub-dashboard, so that rear passengers can easily access and control the vehicle's multimedia system, air conditioning settings and other functions. However, the control screen does not have a flip function, resulting in the control screen still occupying a certain amount of space in the car when not in use, affecting the neatness and space utilization of the car. Utility Model Content

[0004] The utility model aims to provide a screen flipping motion device, which can realize the control screen being folded and retracted into the auxiliary instrument panel when not in use through flipping, thereby improving the cleanliness and space utilization rate of the vehicle interior.

[0005] A screen flipping motion device includes a screen assembly, a driving member, a transmission assembly, a guide rod and a guide plate. The screen assembly includes a screen bracket and a fan-shaped gear connected to the screen bracket. The guide rod extends outward from both ends of the screen bracket. The guide plate is provided with a slide groove. The guide rod is inserted into the slide groove. The transmission assembly is connected to the fan-shaped gear. The driving member drives the transmission assembly to operate so as to realize the forward and reverse movement of the screen bracket along the slide groove.

[0006] In the above technical solution, the screen bracket is used to support and fix the screen to ensure the stability and safety of the screen during the flipping process. The fan gear is connected to the screen bracket, allowing it to realize the flipping movement of the screen bracket by rotation. The driving member is the power source of the entire flipping movement. After receiving the control signal, it starts to work and outputs power. The transmission assembly is responsible for transmitting the power of the driving member to the fan gear to rotate it. The guide rod extends outward from both ends of the screen bracket to play a guiding and supporting role, ensuring that the screen bracket can move along a predetermined trajectory during the flipping process to prevent deviation or shaking. The guide plate is provided with a slide groove, and the guide rod is inserted into these slide grooves. The design of the slide groove limits the movement direction of the guide rod, so that it can only move in a straight line or arc along the trajectory of the slide groove. In this way, when the fan gear rotates, the screen bracket can achieve a stable flipping movement through the cooperation of the guide rod and the guide plate. When the driving member receives the flipping signal, it starts to work and outputs power. The power is transmitted to the fan gear through the transmission assembly, causing it to start rotating. Since the fan gear is connected to the screen bracket, the screen bracket will also move with the rotation of the fan gear. At the same time, the guide rod slides in the slide groove of the guide plate to provide guidance and support for the flipping of the screen bracket. In this way, the screen bracket can flip along the track of the slide groove, thereby achieving the flipping effect of the screen. The utility model realizes that the control screen can be folded and retracted into the auxiliary instrument panel when it is not needed through flipping, thereby improving the neatness and space utilization of the vehicle interior.

[0007] Furthermore, the transmission assembly includes a first gear, a second gear and a rotating shaft, the output end of the driving member is connected to the first gear, the second gear is passed through the rotating shaft and meshes with the first gear, and third gears are connected to both ends of the rotating shaft, and the third gear meshes with the fan gear.

[0008] In the above technical solution, the driving member serves as a power source, and the power generated by the driving member is transmitted step by step through the first gear, the second gear, the rotating shaft and the third gear, and is finally converted into a flipping movement of the screen bracket.

[0009] Furthermore, it also includes a clutch structure, which includes a clutch, a first spring, a first gasket and a baffle, the clutch is engaged with the second gear, the first gasket is abutted against the baffle, and the first spring is arranged between the clutch and the first gasket.

[0010] In the above technical solution, when it is necessary to control the flipping motion of the screen, the clutch structure will be activated. The clutch can be engaged or disengaged through an external control signal (such as electromagnetic force, mechanical force, etc.). When the clutch is engaged, the power is transmitted to the screen bracket through the second gear, the third gear and the fan gear to drive it to flip. When it is necessary to stop or change the flipping direction, the clutch is disengaged to cut off the power transmission path, thereby realizing the control of the flipping motion.

[0011] Furthermore, the slide groove includes a first arc-shaped groove and a second arc-shaped groove, the first arc-shaped groove extends obliquely downward, and the second arc-shaped groove extends obliquely upward.

[0012] In the above technical solution, the first arc groove and the second arc groove extend downward and upward respectively, realizing the bidirectional flipping capability of the screen bracket. This means that the screen bracket can not only flip from the stowed state (located at the beginning of the first arc groove) to the use state (located at the end of the second arc groove), but also flip from the use state to the stowed state, realizing complete bidirectional operation.

[0013] Furthermore, the starting end of the second arc-shaped groove is located vertically above the middle end of the first arc-shaped groove.

[0014] In the above technical solution, the starting end of the second arc groove is located vertically above the middle end of the first arc groove, providing an upward flipping trajectory for the screen bracket, reducing twists and unnecessary movements during the flipping process, and making the flipping action smoother and more efficient.

[0015] Furthermore, two mounting grooves for placing micro switches are provided between the first arc-shaped groove and the second arc-shaped groove, wherein one mounting groove is close to the end of the first arc-shaped groove, and the other mounting groove is close to the beginning of the second arc-shaped groove.

[0016] In the above technical solution, the micro switch is used as a position sensor to accurately detect the position of the screen bracket in the slide slot. When the screen bracket reaches the end of the first arc slot, the micro switch located in the mounting slot at the end of the first arc slot is triggered, indicating that the screen has been unfolded; and when the screen bracket touches the micro switch located in the mounting slot at the beginning of the second arc slot, it indicates that the screen has been completely retracted.

[0017] Furthermore, it also includes a damping structure, which includes a second gasket, a second spring and a sleeve, the second gasket is passed through the guide rod and abuts against the guide plate, the sleeve is arranged at one end of the guide rod away from the screen bracket, and the second spring is arranged between the second gasket and the sleeve.

[0018] In the above technical solution, at the end of the flipping motion, the damping structure provides effective buffering protection. When the screen bracket touches the end of the first arc groove or the beginning of the second arc groove, the second spring can absorb part of the impact energy, reducing the risk of damage to the slide groove and the screen bracket.

[0019] Furthermore, the screen bracket includes a supporting plate and side plates, and the side plates are relatively arranged at two ends of the supporting plate.

[0020] In the above technical solution, the support plate is the main support surface of the screen and is responsible for bearing the weight of the screen. The side plates are relatively arranged at both ends of the support plate to provide additional support and stability for the support plate. This structural design allows the screen bracket to remain stable during the flipping process and is not prone to shaking or tilting, thereby ensuring the stability of the screen.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. Set up a driving member, a transmission assembly and a sector gear. When the driving member receives a flip signal, it starts to work and outputs power. The power is transmitted to the sector gear through the transmission assembly, causing it to start rotating. Since the sector gear is connected to the screen bracket, the screen bracket will also move with the rotation of the sector gear.

[0023] 2. Set the guide rod and the guide plate. When the screen bracket starts to flip, the guide rod slides in the slide groove of the guide plate to provide guidance and support for the flipping of the screen bracket. In this way, the screen bracket can flip along the track of the slide groove, thereby achieving the flipping effect of the screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The screen flip motion device of the present invention will be further described in detail below in conjunction with specific embodiments and drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0039] Please refer to Figure 1 and Figure 2 In a preferred embodiment, the screen flipping motion device of the utility model includes a screen assembly 1, a driving member 2, a transmission assembly 3, a guide rod 4 and a guide plate 5. The screen assembly 1 includes a screen bracket 101 and a fan-shaped gear 102 connected to the screen bracket 101. The guide rod 4 extends outward from both ends of the screen bracket 101. The guide plate 5 is provided with a slide groove 501. The guide rod 4 is inserted into the slide groove 501. The transmission assembly 3 is connected to the fan-shaped gear 102. The driving member 2 drives the transmission assembly 3 to operate to realize the forward and reverse movement of the screen bracket 101 along the slide groove 501.

[0040] In the practical application of the above structure, the screen bracket 101 is used to support and fix the screen to ensure the stability and safety of the screen during the flipping process. The fan gear 102 is connected to the screen bracket 101, allowing it to realize the flipping movement of the screen bracket 101 by rotation. The driving member 2 is the power source of the entire flipping movement. After receiving the control signal, it starts to work and outputs power. The transmission component 3 is responsible for transmitting the power of the driving member 2 to the fan gear 102 to rotate it. The guide rod 4 extends outward from both ends of the screen bracket 101 to play a guiding and supporting role, ensuring that the screen bracket 101 can move along a predetermined trajectory during the flipping process to prevent deviation or shaking. The guide plate 5 is provided with a slide groove 501, and the guide rod 4 is inserted into these slide grooves 501. The design of the slide groove 501 limits the movement direction of the guide rod 4, so that it can only move in a straight line or arc along the trajectory of the slide groove 501. In this way, when the fan gear 102 rotates, the screen bracket 101 can achieve a stable flipping movement through the cooperation of the guide rod 4 and the guide plate 5. When the driving member 2 receives the flipping signal, it starts to work and outputs power. The power is transmitted to the sector gear 102 through the transmission assembly 3, causing it to start rotating. Since the sector gear 102 is connected to the screen bracket 101, the screen bracket 101 will also move with the rotation of the sector gear 102. At the same time, the guide rod 4 slides in the slide groove 501 of the guide plate 5 to provide guidance and support for the flipping of the screen bracket 101. In this way, the screen bracket 101 can flip along the trajectory of the slide groove 501, thereby achieving the flipping effect of the screen. The utility model realizes that the control screen can be folded and retracted into the auxiliary instrument panel when it is not needed through flipping, thereby improving the cleanliness and space utilization of the vehicle.

[0041] Specifically, in one embodiment, the transmission assembly 3 includes a first gear 301, a second gear 302 and a rotating shaft 303, the output end of the driving member 2 is connected to the first gear 301, the second gear 302 is arranged on the rotating shaft 303 and meshes with the first gear 301, and the two ends of the rotating shaft 303 are connected to the third gear 304, and the third gear 304 is meshed with the fan gear 102. The driving member 2 serves as the power source of the entire transmission system. After receiving the control signal, the driving member (such as a motor) starts to work and generates rotational power. The output end of the driving member 2 is directly connected to the first gear 301, so the first gear 301 will rotate with the drive of the driving member 2. The first gear 301 is the starting point of the transmission chain and is responsible for transmitting the power of the driving member 2 to the subsequent gears. The second gear 302 is arranged on the rotating shaft 303 and meshes with the first gear 301. When the first gear 301 rotates, it drives the second gear 302 to rotate on the rotating shaft 303 through meshing. This design realizes the transmission of power and the change of direction. The rotating shaft 303 is a component that supports the second gear 302 and allows it to rotate. At the same time, the third gear 304 is also connected to both ends of the rotating shaft 303, which means that the rotating shaft 303 not only transmits power, but also serves as a bridge connecting the third gear 304. The fan gear 102 is meshed with the third gear 304 at both ends of the rotating shaft 303. Since the third gear 304 is connected to the rotating shaft 303, when the rotating shaft 303 rotates, the third gear 304 will also rotate with it, and drive the fan gear 102 to rotate through the meshing action. The fan gear 102 is connected to the screen bracket 101 and is the final execution component of the transmission chain. When the fan gear 102 rotates, it drives the screen bracket 101 to flip along the slide groove 501 of the guide plate 5. Due to the special shape (fan-shaped) of the fan gear 102, it can realize the flipping of the screen bracket 101 within a certain range.

[0042] Please refer to Figure 2 and Figure 3The utility model also includes a clutch structure 6, which includes a clutch 601, a first spring 602, a first gasket 603 and a baffle 604. The clutch 601 is engaged with the second gear 302, the first gasket 603 is in contact with the baffle 604, and the first spring 602 is arranged between the clutch 601 and the first gasket 603. The clutch 601 is the core component of the clutch structure 6, which is engaged with the second gear 302. When the clutch 601 is in an engaged state, it can transmit the rotational power of the second gear 302 to the subsequent transmission components. The design of the clutch allows it to be separated from the second gear 302 when necessary, thereby interrupting the transmission of power. The first spring 602 is arranged between the clutch 601 and the first gasket 603, and plays a role of resetting and buffering. When the clutch 601 is separated from the second gear 302, the first spring 602 will push the clutch 601 back to its initial position (usually a position separated from the second gear 302). In addition, during the process of the clutch 601 engaging or disengaging with the second gear 302, the first spring 602 can also absorb some impact and vibration to protect other components of the transmission system from damage. The first gasket 603 is in contact with the baffle 604 to adjust the gap between the clutch 601 and the baffle 604 to ensure that the clutch 601 can move smoothly. At the same time, the first gasket 603 can also provide a certain friction force to help the clutch 601 maintain a stable position under certain conditions. The baffle 604 is a fixed component in the clutch structure, which limits the movement range of the clutch 601. When the clutch 601 is engaged with the second gear 302, the baffle 604 plays a supporting or positioning role; when the clutch 601 needs to be separated, the baffle 604 prevents the clutch 601 from continuing to move to an inappropriate position. Specifically, when it is necessary to control the screen flipping movement, the clutch structure 6 will be activated. The clutch 601 can be engaged or separated by an external control signal (such as electromagnetic force, mechanical force, etc.). When the clutch 601 is engaged, power is transmitted to the screen support 101 through the second gear 302, the third gear 304 and the sector gear 102, driving it to flip. When it is necessary to stop or change the flip direction, the clutch 601 is disengaged to cut off the power transmission path, thereby achieving control of the flip motion.

[0043] Please refer to Figure 1 In one embodiment, the slide groove 501 includes a first arc groove 5011 and a second arc groove 5012, the first arc groove 5011 extends obliquely downward, and the second arc groove 5012 extends obliquely upward. The first arc groove 5011 and the second arc groove 5012 extend obliquely downward and upward, respectively, to achieve the bidirectional flipping capability of the screen bracket 101. This means that the screen bracket 101 can not only flip from the stowed state (located at the beginning of the first arc groove 5011) to the use state (located at the end of the second arc groove 5012), but also flip from the use state to the stowed state, to achieve complete bidirectional operation.

[0044] It should be noted that the beginning of the second arc groove 5012 is located vertically above the middle end of the first arc groove 5011. The beginning of the second arc groove 5012 is located vertically above the middle end of the first arc groove 5011, providing an upward flipping trajectory for the screen bracket 101, reducing the twists and turns and unnecessary movements during the flipping process, making the flipping action smoother and more efficient. When the screen bracket 101 flips upward along the second arc groove 5012, it will gradually rise and face the passenger. This vertical movement may bring a dynamic and shocking visual experience to the passengers, enhancing the attractiveness and interactivity of the in-car entertainment system.

[0045] Please refer to Figure 4 In one embodiment, two mounting grooves 502 for placing micro switches 7 are provided between the first arc groove 5011 and the second arc groove 5012, wherein one mounting groove 502 is close to the end of the first arc groove 5011, and the other mounting groove 502 is close to the beginning of the second arc groove 5012. The micro switch 7 is used as a position sensor and can accurately detect the position of the screen bracket 101 in the slide groove. When the screen bracket 101 reaches the end of the first arc groove 5011, the micro switch 7 located in the mounting groove 502 at the end of the first arc groove 5011 is triggered, indicating that the screen has been unfolded; and when the screen bracket 101 touches the micro switch 7 located in the mounting groove 502 at the beginning of the second arc groove 5012, it indicates that the screen has been completely retracted.

[0046] Furthermore, the utility model also includes a damping structure 8, which includes a second gasket 801, a second spring 802 and a sleeve 803. The second gasket 801 is inserted into the guide rod 4 and abuts against the guide plate 5. The sleeve 803 is arranged at the end of the guide rod 4 away from the screen bracket 101, and the second spring 802 is arranged between the second gasket 801 and the sleeve 803. The second spring 802, as a damping element, can provide appropriate resistance during the flipping process of the screen bracket 101. By adjusting the stiffness and preload of the second spring 802, the stop position of the screen bracket 101 during the flipping process can be controlled. When the screen bracket 101 approaches the micro switch 7, the effect of the damping structure 8 will gradually increase, so that the screen bracket 101 can slowly and stably stop at a predetermined position. At the end of the flipping movement, the damping structure 8 provides effective buffering protection. When the screen bracket 101 touches the end of the first arc groove 5011 or the beginning of the second arc groove 5012 , the second spring 802 can absorb part of the impact energy, thereby reducing the risk of damage to the slide groove 501 and the screen bracket 101 .

[0047] Please refer to Figure 2The screen bracket 101 includes a supporting plate 1011 and side plates 1012, and the side plates are relatively arranged at the two ends of the supporting plate. The supporting plate 1011 is the main supporting surface of the screen and is responsible for bearing the weight of the screen. The side plates 1012 are relatively arranged at the two ends of the supporting plate 1011, providing additional support and stability for the supporting plate 1011. This structural design allows the screen bracket 101 to remain stable during the flipping process, and is not prone to shaking or tilting, thereby ensuring the stability of the screen.
