Description
Technical Field
[0001] This utility model relates to the technical field of sunshade curtain storage devices, and in particular to a panoramic sunshade curtain storage device integrated with a sunroof. Background Technology
[0002] With the development of the automotive industry and consumers' increasing demands for driving and riding experiences, panoramic sunroofs have become standard or popular optional features in more and more car models. Compared with traditional small sunroofs, panoramic sunroofs provide a wider field of vision and better lighting for the interior, greatly enhancing the sense of spaciousness and comfort.
[0003] However, while the large glass roof provides a wide field of vision, it also causes the interior temperature to rise rapidly in summer or under strong sunlight, and the intense glare can affect the driver's vision and passenger comfort. Therefore, equipping a panoramic sunroof with a sunshade has become almost a necessity.
[0004] To enhance ease of use and technological appeal, mainstream sunshades on the market have evolved from early manual models to motor-driven electric models. Drivers or passengers can easily control the opening and closing of the sunshade with just a button, greatly simplifying operation.
[0005] However, the automatic closing process of motorized sunshades also presents a significant safety hazard. When there are foreign objects in the path of the sunshade, especially a passenger's unintentionally extended hand or placed items, the continuous driving force of the motor can cause pinching injuries or damage to the motor and its transmission mechanism if an effective anti-pinch protection mechanism is lacking. Some existing electronic anti-pinch solutions rely on detecting changes in motor current to determine if an obstacle has been encountered, but this method suffers from response delays, unstable sensitivity, or failure due to electrical control system malfunctions. Its reliability still has room for improvement. Therefore, this invention proposes a panoramic sunshade integrated storage device to address the shortcomings of existing technologies. Summary of the Invention
[0006] To overcome the above shortcomings, this utility model provides a panoramic sunroof integrated sunshade curtain device, which aims to improve the problem that some existing panoramic sunroof integrated sunshade curtain devices lack a reliable mechanical anti-pinch protection mechanism during the closing process, which can easily cause pinching injuries to people or damage to the motor.
[0007] This utility model provides a panoramic sunroof integrated sunshade curtain device, including: an outer shell and a sunshade mechanism disposed within the outer shell, the sunshade mechanism including a motor and a sunshade cloth; it also includes an anti-pinch mechanism.
[0008] The anti-pinch mechanism is located between the motor and the transmission part of the sunshade mechanism. As a mechanical torque clutch, the anti-pinch mechanism is used to interrupt power transmission when the drive load is abnormal.
[0009] Furthermore, the anti-pinch mechanism includes an upper friction plate, a fixed column, a movable column, a spring, a connecting column, and a lower friction plate; the upper friction plate is rotatably disposed within the housing and is connected to the drive end of the motor; the fixed column is fixedly connected to the top of the upper friction plate; the movable column is slidably connected to the inside of the fixed column, enabling it to perform axial displacement; the spring is sleeved on the outside of the movable column for applying preload; the connecting column is fixedly connected to the bottom of the movable column; the lower friction plate is fixedly connected to one side of the connecting column, abutting against the upper friction plate, and transmitting power to the sunshade mechanism under the pressure of the spring to drive the sunshade cloth.
[0010] Preferably, one end of the spring abuts against a radially extending annular structure on the movable column, and the other end abuts against the bottom of the fixed column. The spring precisely sets the maximum allowable torque threshold between the upper friction plate and the lower friction plate by applying axial pressure.
[0011] Preferably, the transmission part of the sunshade mechanism includes a gear and a rotating column. The lower friction plate is fixedly connected to the gear via a transmission shaft to transmit power from the anti-pinch mechanism to the gear; the rotating column is fixedly connected to one side of the gear for directly winding or unwinding the sunshade fabric.
[0012] Preferably, the sunshade mechanism further includes a rack and a slider. The rack is slidably connected to both sides of the housing, serving as a transmission and guiding component; the slider is slidably connected to a groove inside the housing, and is fixedly connected to the front end of the sunshade cloth, for driving the sunshade cloth to move horizontally when it is unfolded or retracted.
[0013] Preferably, the gear meshes with the rack. When the gear rotates under power, its rotational motion is stably converted into the linear motion of the rack through meshing, thereby driving the connected slider to move synchronously and smoothly.
[0014] Preferably, the panoramic sunroof integrated sunshade device further includes a support assembly, which includes a fixing plate and a guide rail. The fixing plate is used to mount the device as a whole on the top of the vehicle body; the guide rail is fixedly connected to both sides of the fixing plate and is used to provide precise guidance and support for the linear movement of the slider.
[0015] Preferably, the outer casing has a groove that mates with the guide rail, which facilitates the installation and fixation of the outer casing along the guide rail. A sunroof is fixedly connected to the top of the vehicle body, and the fixing plate secures the outer casing to the top of the sunroof, ensuring that the sunshade mechanism can accurately shade the sunroof area.
[0016] Preferably, wheels are fixedly connected to the bottom of the vehicle body, and the vehicle body serves as the installation base and carrier for the entire device.
[0017] This utility model has the following beneficial effects: 1. This utility model solves the safety hazard of existing electric sunshades encountering obstacles during closing, which may result in injury to personnel or damage to the motor due to untimely response or control system failure. It achieves rapid and reliable overload protection and anti-pinch function by interrupting power and generating displacement signal through pure mechanical clutch slippage, significantly improving the safety of use.
[0018] 2. This utility model solves the problems of scattered components, complex structure, and large space occupation of traditional vehicle sunshade devices by integrating the sunshade mechanism, anti-pinch mechanism, and support components into a compact shell, achieving the technical effect of compact structure, high degree of modularity, and easy production, installation and maintenance.
[0019] 3. This utility model utilizes a spring to set a preload force, causing the friction plate to automatically slip when the torque threshold is exceeded, thereby triggering protection. This solves the problem that traditional electronic anti-pinch solutions that rely on motor current detection are prone to failure or misjudgment due to current fluctuations, sensor delays, or controller malfunctions. It achieves the technical effect of direct anti-pinch response, high reliability, and independence from the status of the electronic control system. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0023] Reference Figures 1 to 4 This utility model provides a panoramic sunshade curtain storage device, which aims to solve the problem that existing electric sunshades lack a reliable mechanical anti-pinch structure during the closing process, thus posing a safety hazard.
[0024] like Figure 1 As shown, the panoramic sunroof integrated sunshade curtain device includes a housing 33, and a sunshade mechanism 2 and an anti-pinch mechanism 4 housed inside the housing 33. The anti-pinch mechanism 4 is located between the motor 21 of the sunshade mechanism 2 and the transmission part of the sunshade mechanism 2, and is used to interrupt power transmission when the drive load is abnormal, so as to realize mechanical overload protection.
[0025] Reference Figure 4The anti-pinch mechanism 4 includes an upper friction plate 41, a fixed post 42, a movable post 43, a spring 44, a connecting post 45, and a lower friction plate 46. The upper friction plate 41 is rotatably disposed inside the housing 33 and is connected to the drive end of the motor 21 to receive the driving force from the motor 21. The bottom of the fixed post 42 is fixedly connected to the top of the upper friction plate 41, forming a structure for accommodating the movable part. The movable post 43 is slidably connected inside the fixed post 42, allowing the movable post 43 to reciprocate along the axial direction of the fixed post 42. The spring 44 is sleeved on the outside of the movable post 43, with one end of the spring abutting against... The ring structure extending radially from the moving column 43 is connected at one end and abuts against the bottom of the fixed column 42 at the other end. This allows the torque threshold transmitted between the upper friction plate 41 and the lower friction plate 46 to be set by axial pressure. The connecting column 45 is fixedly connected to the end of the moving column 43 away from the fixed column 42, i.e., the bottom of the moving column 43. The lower friction plate 46 is fixedly connected to one side of the connecting column 45. The friction surface of the lower friction plate 46 abuts against the friction surface of the upper friction plate 41. Under the axial pressure applied by the spring 44, the rotational power of the upper friction plate 41 is transmitted to the lower friction plate 46 through friction, and finally drives the sunshade mechanism 2 to operate.
[0026] Reference Figure 2 and Figure 3 The rotating column 23 is fixedly connected to one side of the gear 22, and its axis coincides with or is parallel to the rotation center of the gear 22. The rotating column 23 is used to directly wind or unwind the sunshade cloth 26. When the gear 22 rotates, the rotating column 23 rotates synchronously, thereby realizing the winding or unfolding operation of the long strip of sunshade cloth 26.
[0027] The sunshade mechanism 2 also includes a rack 24 and a slider 25, which are used to guide and drive the front end of the sunshade cloth 26 to move smoothly. The rack 24 is slidably connected to both sides of the housing 33, providing guidance and transmission basis for the movement of the slider 25. The slider 25 is slidably connected to the groove opened inside the housing 33, and the slider 25 is fixedly connected to the front end of the sunshade cloth 26. In the assembled state, the gear 22 meshes with the rack 24. When the gear 22 rotates, its rotational motion is converted into the linear motion of the rack 24 through the meshing action, which in turn drives the slider 25 connected to it to move horizontally synchronously in the groove of the housing 33, thereby pulling the sunshade cloth 26 to unfold or retract smoothly.
[0028] like Figure 1 As shown, the support assembly 3 includes a fixed plate 31 and a guide rail 32. The fixed plate 31 is used to install the entire device on the top of the vehicle body 1, and the bottom of the vehicle body 1 is fixedly connected to the wheels 35. The guide rail 32 is fixedly connected to both sides of the fixed plate 31 and is used to guide the slider 25 to move smoothly in a straight line.
[0029] The outer shell 33 has a groove that matches the shape and size of the guide rail 32. The outer shell 33 is installed and fixed on the support component 3 by sliding or snapping the groove with the guide rail 32. At the same time, the top of the vehicle body 1 is fixedly connected to the sunroof 34. The fixing plate 31 finally fixes the outer shell 33 to the top of the sunroof 34, so that the sunshade mechanism 2 can accurately shade the sunroof 34 area.
[0030] The implementation principle of this application embodiment is as follows: When the vehicle is running, the vehicle body 1 serves as the installation base for the entire device. The support component 3 is fixedly connected to the top of the vehicle body 1, forming a stable installation platform. The guide rail 32 is fixedly connected to both sides of the fixing plate 31, providing precise guidance and facilitating installation. The outer shell 33 has a groove that cooperates with the guide rail 32 to firmly install the outer shell 33 on the top of the sunroof 34. The sunroof 34 is fixedly connected to the top of the vehicle body 1, providing an installation base. The wheels 35 are fixedly connected to the bottom of the vehicle body 1, allowing the vehicle body 1 to move smoothly. When the weather is hot, the sunshade mechanism 2 can unfold the sunshade cloth 26 to block sunlight. The motor 21 is fixedly connected to one side of the outer shell 33, providing driving force. The drive end of the motor 21 is fixedly connected to a gear 22. The rotating column 23 is fixedly connected to one side of the gear 22. When the gear 22 rotates, the sunshade cloth 26 is released. The rack 24 is slidably connected to both sides of the outer shell 33, providing guidance and a base for movement. The slider 25 is slidably connected to a groove inside the outer shell 33, driving the sunshade cloth 26 to move horizontally.
[0031] When the driver accidentally places their hand on the path of the sunshade mechanism 2, the anti-pinch mechanism 4 ensures that the hand will not be damaged. The upper friction plate 41 is fixedly connected to the inside of the housing 33, transmitting the driving force of the motor 21. The fixed column 42 is fixedly connected to the top of the upper friction plate 41. The moving column 43 is slidably connected to the inside of the fixed column 42, converting the overload torque signal into a linear displacement signal. The spring 44 is sleeved on the outside of the moving column 43, providing a rebound force. The connecting column 45 is fixedly connected to the bottom of the moving column 43. The lower friction plate 46... Fixed to one side of the connecting column 45, when encountering an obstacle, the movement of the sunshade 26 is obstructed, causing a sharp increase in the drive load. This causes the torque that needs to be transmitted between the lower friction plate 46 and the upper friction plate 41 to exceed the threshold set by the spring 44. At this time, the friction pair slips. The upper friction plate 41 is still rotating, but the lower friction plate 46 stops or its speed decreases, forcing the moving column 43 to compress the spring 44 and generate axial displacement, causing the motor 21 to stop or reverse, thereby causing the sunshade 26 to stop and move in the opposite direction a short distance to release the obstacle.
