Description

Technical Field

[0001] This utility model relates to the field of automotive roof technology, specifically to a sunroof-type automotive roof based on a linkage support structure. Background Technology

[0002] The prototype of the car sunroof can be traced back to the lift-up roof design of the 1915 Ford Model T, initially designed to solve the problem of insufficient lighting in boxy car bodies. In 1932, the Seven Box Saloon in Austin, England, achieved the first mass-produced sunroof, whose core structure included glass, a sealing system, and a manual drive mechanism, focusing primarily on ventilation. After World War II, the advent of electric sunroofs, with their motor-driven sliding / tilting mechanisms, significantly improved operational convenience.

[0003] Current electric sunroofs typically use a continuous rail sliding mechanism to open or close. However, this method generally presents problems such as difficulty in motor maintenance because the motor is built into the rail. In addition, the sunroof opening mode is relatively limited. Therefore, a new type of sunroof-type car roof is needed to optimize the above-mentioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sunroof-type car roof based on a linkage support structure.

[0005] The technical solution of this utility model is: a sunroof-type car roof based on a linkage support structure, including a roof sheet and a roof liner, wherein the roof liner is fixedly installed on the lower surface of the roof sheet. The roof sheet and the roof liner are respectively provided with a sunroof mounting upper hole and a sunroof mounting lower hole in the middle. A set of sunroof slide rails are provided on the left and right sides of the sunroof mounting upper hole. A set of linkage support structures are provided on the front and rear sides of the sunroof mounting upper hole. The linkage support structure includes a drive rod, a transmission belt set on a set of sunroof slide rails, and a diameter-length adjustable pulley set on the drive rod for engaging with the transmission belt. The two transmission belts are respectively fixedly connected to one end of the sunroof. The drive rod is provided with a driver for controlling the diameter-length variation of the diameter-length adjustable pulley, which controls the tension of the transmission belt by the diameter-length variation of the adjustable pulley to support the sunroof to be raised from the sunroof mounting lower hole to the sunroof mounting upper hole and docked with the sunroof slide rail.

[0006] Furthermore, the adjustable diameter pulley consists of a pulley body and a sliding pulley plate circumferentially slidable on the pulley body, and the sliding pulley plate is connected to the pulley body through a first airbag rod.

[0007] Explanation: The adjustable pulley design allows the expansion and contraction of the air spring rod to control the pulley's length. The driver increases the pulley's length, which in turn supports the sunroof and lifts it to the position of the sunroof rails via the drive belt, thus meeting the drive control requirements of this practical automotive roof system.

[0008] Furthermore, the actuator includes a first airbag ring disposed on a drive rod and a drive member for compressing the first airbag ring, the first airbag ring being in communication with the first airbag rod.

[0009] Note: The above-mentioned drive can well meet the shape driving adjustment of the adjustable diameter pulley. At the same time, it can be understood that the above-mentioned air bladder ring and air bladder rod can also be liquid bladder ring and liquid bladder rod, with the same working principle. No specific limitation is made here, as long as the shape driving adjustment of the adjustable diameter pulley can be achieved.

[0010] Furthermore, the sunroof consists of a support frame and a sunroof panel connected to the support frame via a scissor lift frame. The drive rod is provided with a second airbag ring, and the lower hole for mounting the sunroof is provided with a second airbag rod for supporting the sunroof panel to move upward and open. The second airbag rod is connected to the second airbag ring, and the drive rod is provided with a drive component for squeezing the second airbag rod.

[0011] Note: The above-described sunroof structural design enables a vertical lifting and opening effect, thus providing two opening methods for sunroof-type car roofs: a side-sliding and concealing opening method, and a vertical lifting opening method, offering users multiple usage experiences to meet the needs of different customers.

[0012] Furthermore, the driving component is an electric push rod, a hydraulic cylinder, or a nut driven to rotate by a rotary motor.

[0013] Note: The above-mentioned driving component can meet the driving requirements of this utility model. It is also understood that the above-mentioned driving component can be other commercially available driving components that meet the same driving effect. Their working principle is the same, and no specific limitation is made here. They can all drive the expansion and contraction of the first airbag rod and the second airbag rod.

[0014] The beneficial effects of this utility model are:

[0015] (1) The sunroof type car roof of this utility model controls the lowering or raising of the sunroof by using a linkage support structure, and integrates the translation drive of the sunroof, thereby greatly optimizing the arrangement of the drive components, providing a new design idea for sunroof type car roofs, and further improving the sealing performance of the car interior through the small lifting support of the sunroof.

[0016] (2) The sunroof type car roof of this utility model can achieve the effect of vertical lifting and opening through the structural design of the sunroof, thus providing two opening methods for the sunroof type car roof: side sliding and vertical lifting, to meet the different usage needs of customers.

Detailed Implementation

[0026] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0027] Example 1: A sunroof-type car roof based on a linkage support structure, such as Figures 1-3As shown, the vehicle includes a roof sheet 1 and a roof liner 2, with the roof liner 2 fixedly mounted on the lower surface of the roof sheet 1. The roof sheet 1 and the roof liner 2 have corresponding upper sunroof mounting holes 3 and lower sunroof mounting holes 4 in their middle sections. A set of sunroof sliding rails 5 is provided on each of the left and right sides of the upper sunroof mounting hole 3. A set of linkage support structures is provided on each of the front and rear sides of the upper sunroof mounting hole 3. It can be understood that an inner cavity for accommodating the sunroof is provided within the roof sheet 1 on the rear side of the upper sunroof mounting hole 3; that is, the linkage support structure located on the rear side is positioned on the rear side of the inner cavity to ensure sufficient space within the inner cavity to accommodate the sunroof. For example... Figure 5 , Figure 6 As shown, the linkage support structure includes a drive rod 6, a transmission belt 7 mounted on a set of sunroof slide rails 5, and a diameter-length adjustable pulley 8 mounted on the drive rod 6 for engaging with the transmission belt 7. The diameter-length adjustable pulley 8 consists of a pulley body 81 and a sliding pulley piece 82 circumferentially slidably mounted on the pulley body 81. The sliding pulley piece 82 is connected to the pulley body 81 via a first airbag rod 83.

[0028] like Figure 4 As shown in Figure 5, two transmission belts 7 are fixedly connected to one end of the sunroof 10. The drive rod 6 is equipped with a driver 9 for controlling the diameter variation of the adjustable pulley 8. The driver 9 controls the tension of the transmission belts 7 by adjusting the diameter of the adjustable pulley 8 to support the sunroof as it is lifted from the lower sunroof mounting hole 4 to the upper sunroof mounting hole 3 and docks with the sunroof slide rail 5. The driver 9 includes a first airbag ring 91 mounted on the drive rod 6 and a drive component 92 for compressing the first airbag ring 91. The first airbag ring 91 is connected to the first airbag rod 83. The drive component 92 is a hydraulic cylinder.

[0029] The operation method of the sunroof-type car roof is as follows: the driver 9 is started to compress the first airbag ring 91, thereby extending each first airbag rod 83, increasing the diameter of the adjustable pulley 8, and thus tensioning the transmission belt 7 to raise the connected sunroof 10 from the lower sunroof mounting hole 4 to the upper sunroof mounting hole 3 so that it docks with the sunroof slide rail 5. Then, the commercially available rotary motor is started to drive the drive rod 6 to rotate. Under the action of belt transmission, the sunroof 10 moves into the inner cavity of the roof sheet metal 1, thereby realizing the movement and opening of the sunroof 10. During the opening of the sunroof 10, the drive component 92 can be reset to avoid increasing the pressure of the first airbag ring 91 and the first airbag rod 83 due to long-term start-up. For example, the program is set to reset the drive component 92 after opening for more than 1 minute, thereby also ensuring the response speed of the sunroof during short-term opening and closing.

[0030] Meanwhile, in order to improve transmission efficiency, the transmission belt can be a toothed belt, and the outer end face of the sliding pulley 82 is provided with teeth that are assembled with the toothed belt.

[0031] Example 2: This example differs from Example 1 in that, as Figures 6-8 As shown, the sunroof 10 consists of a support frame 101 and a sunroof panel 103 connected to the support frame 101 via a commercially available scissor lift frame 102. The drive rod 6 is provided with a second airbag ring 93, and the lower sunroof mounting hole 4 is provided with a second airbag rod 94 for supporting the sunroof panel 103 to move upward and open. The second airbag rod 94 is circumferentially distributed on the surrounding frame of the lower sunroof mounting hole 4. The second airbag rod 94 is connected to the second airbag ring 93. The drive rod 6 is provided with a drive component 92 for pressing the second airbag rod 94. The drive component 92 is a hydraulic cylinder.

[0032] The above-mentioned sunroof type car roof operation method is as follows: Based on embodiment 1, when the sunroof 10 is in the closed state, the second airbag rod 94 on the other side is squeezed by the start drive component 92, so that each second airbag rod 94 extends, thereby lifting the sunroof panel 103 to move upward and realize vertical lifting and opening.

[0033] Example 3: The difference between this example and Example 1 is that the driving component 92 is a commercially available electric push rod.

[0034] Example 4: The difference between this example and Example 1 is that the driving component 92 is a nut driven by a commercially available rotary motor.
