Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted equipment, and more specifically, to an intelligent anti-pinch structure for a vehicle-mounted display device. Background Technology

[0002] With the intelligent development of in-vehicle electronic devices, adjustable displays are widely used in vehicles. To meet the needs of different usage scenarios, in-vehicle displays generally adopt a multi-link structure to achieve flipping and angle adjustment functions. However, during operation, the area where the display connects to the base can easily form a dynamically changing clamping space. If a user's fingers are inserted into this clamping space, there is a risk of pinching injury.

[0003] Existing anti-pinch technologies mostly employ indirect detection methods, such as monitoring changes in the drive motor current. These solutions exhibit hysteresis in response to sudden clamping actions and cannot effectively cover the entire risk area formed by the movement trajectory of mechanical components. While some optical detection solutions can achieve non-contact detection, they are prone to misjudgment under the complex lighting conditions of the in-vehicle environment. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent anti-pinch structure for vehicle-mounted display devices, which can improve the sensitivity and accuracy of sensing and enhance the safety of the device.

[0005] A smart anti-pinch structure for an in-vehicle display device includes a base, a drive assembly, and a flip assembly. The drive assembly is disposed on the base. The flip assembly includes a seat and a rotating rod. The seat is rotatably connected to the output end of the drive assembly. The two ends of the rotating rod are rotatably connected to the seat and the base, respectively. The drive assembly is configured to drive the seat to move linearly, causing the seat and the rotating rod to rotate relative to each other to form a fold. A touch-sensitive film is attached to the surface of the seat facing the rotating rod.

[0006] In the above technical solution, the drive component can drive the base to move linearly along a predetermined path. Simultaneously, through the rotational connection between the rotating rod and the base, the linear motion is converted into a flipping action, thereby achieving smooth flipping of the display device within a limited space. The touch-sensitive diaphragm is directly located in the folding area between the base and the rotating rod. When a human body or foreign object enters the folding area, the diaphragm triggers a signal upon contact. Compared to traditional detection methods, this eliminates the signal transmission delay between the sensor and the actuator, making the anti-pinch structure more sensitive and accurate, and improving the anti-pinch effect.

[0007] Furthermore, the seat includes a connecting portion and arm portions extending parallel from both ends of the connecting portion. The rotating rod is rotatably connected between the two arm portions, and a through groove is formed between the two arm portions for the rotating rod to fold and extend into.

[0008] In the above technical solution, the parallel extension of the arm forms a symmetrical support structure, which maintains the stability of the seat and provides clearance for the folding action of the rotating rod through the through groove, thus avoiding structural interference between mechanical parts.

[0009] Furthermore, the touch-sensitive diaphragm is U-shaped and is attached to the surface of the connecting part and the two arms.

[0010] In the above technical solution, the touch sensing diaphragm adheres to the surface of the connecting part and the arm to form a surrounding detection area. When the rotating rod is folded into the through groove, this structure can cover all potential clamping surfaces between the seat and the rotating rod, eliminating detection blind spots.

[0011] Furthermore, the touch-sensitive film includes a sensing layer, a first adhesive layer, a second adhesive layer, and an outer layer. The first adhesive layer and the second adhesive layer are respectively disposed on two surfaces of the sensing layer. The sensing layer is attached to the base through the first adhesive layer, and the outer layer is connected to the sensing layer through the second adhesive layer.

[0012] In the above technical solution, the sensing layer is bonded to the base through the first adhesive layer, and the appearance layer is bonded to the sensing layer through the second adhesive layer, thereby achieving a stable connection between the multi-layer structure.

[0013] Furthermore, the outer layer is a black polycarbonate layer.

[0014] In the above technical solution, black polycarbonate can reduce the reflection of the sensing layer and avoid affecting the display effect and overall aesthetics of the device due to light reflection.

[0015] Furthermore, the driving assembly includes a driving component, a lead screw, and a slider. The output end of the driving component is connected to the lead screw, the slider is threadedly connected to the lead screw, and the base is rotatably connected to the slider.

[0016] In the above technical solution, the lead screw drive mechanism converts rotary motion into precise linear displacement, and the rotational folding of the seat and rotating rod is achieved through the rotational connection between the slider and the seat. This power transmission method achieves high-precision displacement control within a limited space, ensuring the smoothness and reliability of the flipping action.

[0017] Furthermore, a connecting rod is provided on the side of the seat body near the slider, a guide plate is provided between the slider and the seat body, the guide plate is provided with a track groove, and the connecting rod passes through the track groove and is rotatably connected to the slider.

[0018] In the above technical solution, the track groove of the guide plate can limit the movement path of the connecting rod, thereby controlling the flipping path of the seat and the rotating rod, ensuring the smooth and stable flipping action.

[0019] Furthermore, the extension direction of the track groove has an angle with the horizontal direction.

[0020] In the above technical solution, the inclined track groove has the function of guiding the seat body, so that the seat body moves and flips along the preset path.

[0021] Furthermore, the driving component and the flipping component are in two sets, and the two sets of driving components and flipping components are arranged in a mirror image on the base.

[0022] In the above technical solution, the symmetrical arrangement of the driving component and the flipping component can balance the force on the display device, ensuring that the force on the display device is balanced during the flipping process, making the flipping more stable.

[0023] Furthermore, the seat is connected to the vehicle-mounted display device.

[0024] Compared with existing technologies, the advantages of this invention are: the driving component can drive the base to move linearly along a predetermined path, and simultaneously, through the rotational connection between the rotating rod and the base, the linear motion is converted into a flipping action, thereby achieving smooth flipping of the display device within a limited space. The touch-sensitive diaphragm is directly located in the folding area between the base and the rotating rod. When a human body or foreign object enters the folding area, the diaphragm triggers a signal upon contact. Compared with traditional detection methods, this eliminates the signal transmission delay between the sensor and the actuator, making the anti-pinch structure more sensitive and accurate, and improving the anti-pinch effect.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] Please refer to Figure 1 In a preferred embodiment, the intelligent anti-pinch structure of the vehicle-mounted display device of this utility model mainly includes a base 1, a driving component 2, and a flipping component 3. The driving component 2 is disposed on the base 1. The flipping component 3 includes a seat 31 and a rotating rod 32. The seat 31 is rotatably connected to the output end of the driving component 2. The two ends of the rotating rod 32 are rotatably connected to the seat 31 and the base 1, respectively. The driving component 2 is configured to drive the seat 31 to move linearly, causing the seat 31 and the rotating rod 32 to rotate relative to each other to form a fold. A touch-sensitive film 4 is attached to the surface of the seat 31 facing the rotating rod 32.

[0035] For example, the base 1 provides the mounting foundation and support for the overall structure. In specific implementations, the base 1 can be installed in the location within the driver's cabin of a motor vehicle where a display device needs to be installed, such as the center console, roof, or the back of the front seats. The drive assembly 2 is mounted on the base 1, and the seat 31 is connected to a display device (not shown), which can be an existing display screen. The drive assembly 2 can drive the seat 31 to move linearly along a predetermined path, and simultaneously, through the rotational connection between the rotating rod 32 and the seat 31 and the base 1, converts the linear motion into a flipping action, thereby achieving smooth flipping of the display device within a limited space. The touch-sensitive diaphragm 4 is directly disposed in the folding area between the seat 31 and the rotating rod 32. When a human body or foreign object enters the folding area, the diaphragm triggers a signal upon contact. Compared to traditional detection schemes, this eliminates the signal transmission delay between the sensor and the actuator, making the anti-pinch structure more sensitive and accurate, and improving the anti-pinch effect.

[0036] Please refer to Figure 2 The seat 31 includes a connecting portion 311 and arms 312 extending parallel to both ends of the connecting portion 311. A rotating rod 32 is rotatably connected between the two arms 312, and a through groove is formed between the two arms 312 for the rotating rod 32 to fold and extend into. For example, the seat 31 is generally U-shaped. One side of the connecting portion 311 is connected to the drive assembly 2. The two arms 312 extend parallel to each other in the same direction from both ends of the connecting portion 311. A pivot is provided at the end of each arm 312 away from the connecting portion 311, and the rotating rod 32 is rotatably connected between the two arms 312 via the pivot. The parallel extension of the arms 312 forms a symmetrical support structure, maintaining the stability of the seat 31 while providing clearance for the folding action of the rotating rod 32 through the through groove, thus avoiding structural interference between mechanical components.

[0037] Please refer to Figure 5 The touch-sensitive diaphragm 4 is U-shaped and is attached to the surfaces of the connecting part 311 and the two arms 312. The touch-sensitive diaphragm 4 adheres to the surfaces of the connecting part 311 and the arms 312, forming a surrounding detection area. When the rotating rod 32 is folded into the through groove, this structure can cover all potential clamping surfaces between the seat 31 and the rotating rod 32, eliminating detection blind spots.

[0038] Specifically, the touch-sensitive film 4 includes a sensing layer 41, a first adhesive layer 42, a second adhesive layer 43, and an outer layer 44. The first adhesive layer 42 and the second adhesive layer 43 are respectively disposed on the two surfaces of the sensing layer 41. The sensing layer 41 is attached to the base 31 through the first adhesive layer 42, and the outer layer 44 is connected to the sensing layer 41 through the second adhesive layer 43. For example, the first adhesive layer 42 and the second adhesive layer 43 can be double-sided adhesive, the sensing layer 41 can be a touch-sensitive FPC (Flexible Printed Circuit), and the outer layer 44 is a black polycarbonate layer. Black polycarbonate can reduce the reflection of the sensing layer 41, avoiding the impact of light reflection on the display effect and overall aesthetics of the device. The sensing layer 41 is bonded to the base 31 through the first adhesive layer 42, and the outer layer 44 is bonded to the sensing layer 41 through the second adhesive layer 43, thereby achieving a stable connection between the multi-layer structure.

[0039] Please refer to Figure 3 and Figure 4The drive assembly 2 includes a drive component 21, a lead screw 22, and a slider 23. The output end of the drive component 21 is connected to the lead screw 22, the slider 23 is threadedly connected to the lead screw 22, and the base 31 is rotatably connected to the slider 23. The lead screw 22 transmission mechanism converts rotational motion into precise linear displacement, and the rotational folding of the base 31 and the rotating rod 32 is achieved through the rotational connection between the slider 23 and the base 31. This power transmission method achieves high-precision displacement control within a limited space, ensuring the smoothness and reliability of the flipping action.

[0040] A connecting rod 313 is provided on the side of the seat 31 near the slider 23. A guide plate 5 is provided between the slider 23 and the seat 31. The guide plate 5 has a track groove 51. The connecting rod 313 passes through the track groove 51 and is rotatably connected to the slider 23. The extension direction of the track groove 51 forms an angle with the horizontal direction. The track groove 51 of the guide plate 5 can limit the movement path of the connecting rod 313, thereby controlling the flipping path of the seat 31 and the rotating rod 32, ensuring a smooth and stable flipping action. The inclined track groove 51 has a guiding function for the seat 31, causing the seat 31 to move and flip along a preset path.

[0041] In this embodiment, the driving component 2 and the flipping component 3 are two sets, which are arranged in a mirror image on the base 1. The symmetrical arrangement of the driving component 2 and the flipping component 3 can balance the force on the display device, ensuring that the force on the display device is balanced during the flipping process, making the flipping more stable.
