Description

Technical Field

[0001] The utility model relates to the technical field of automobile sunroofs, in particular to a sunroof assembly and a vehicle. Background Art

[0002] The roof of a car is usually fixed or partially open, and is blocked by a roof beam. Passengers cannot break through the roof and can only use the space inside the car. The vehicle cannot be expanded. There are many types of car roofs. The conventional roof types are as follows: 1) All-glass roof, common in sedan models; 2) Small sunroof roof, common in sedan and SUV models; 3) Segmented panoramic sunroof roof, common in sedan models; 4) Convertible roof, common in sports car models.

[0003] There are the following problems:

[0004] 1. Full glass roof: Currently the most common application solution for new energy vehicle models, with large-size fixed glass and good lighting. However, since the full glass roof is connected to the body through PU glue, the roof is fixed and cannot be opened, the ventilation, air permeability and heat dissipation in the car are poor, and the height space of the vehicle cannot be expanded during outdoor activities.

[0005] 2. Small sunroof roof: The movable sunroof is installed on the roof cover by screwing, which can meet the general ventilation needs of daily car use, but the opening size is small, and the roof is arranged with fixed beams and fixed roof parts, which has great limitations in space expansion.

[0006] 3. Segmented panoramic sunroof roof: Compared with the small sunroof roof, the segmented panoramic sunroof roof significantly improves the light transmission effect. However, due to the limitations of the segmented layout and opening method of the sunroof, the openable size has not been substantially improved, and the vertical expansion space provided to the cabin is relatively limited.

[0007] 4. Convertible roof: Due to the complex mechanical structure and structural strength limitations, it cannot be installed on vehicles of conventional size and styling, and therefore only appears on vehicles with smaller roof sizes, such as two-door two-seater sports cars. It has disadvantages such as poor practicality, high cost, and poor body rigidity. In addition, the folded roof occupies the trunk space, making it inconvenient to store luggage for daily travel.

DETAILED DESCRIPTION

[0034] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0035] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0036] See also Figure 1 and Figure 2 As shown, a segmented panoramic sunroof roof is shown, the segmented panoramic sunroof 40 includes a movable glass 401 and a fixed glass 402, the movable glass 401 is arranged on the top of the car, and can be opened and closed and moved relative to the top of the car. Compared with a small sunroof roof, the segmented panoramic sunroof 40 significantly improves the light transmission effect. However, due to the limitations of the segmented arrangement and opening method of the sunroof, the openable size has not been substantially improved, and the vertical expansion space provided to the cabin is relatively limited.

[0037] With the development of society and the progress of the times, consumers' demand for automobile products is no longer just a means of travel, but to meet the scene needs of all passengers during travel. Today's consumers pursue life experiences such as self-driving tours, outdoor expansion, and closeness to nature. Therefore, there are more demands for the ride comfort, space expansion, and function expansion of automobile products. More and more users have more and more demands for outdoor scenes such as camping and travel photography. The roof form of traditional cars cannot meet the daily needs of all passengers in the car when driving and riding, and it cannot meet the functional expansion needs of a family in outdoor activities. Therefore, how to achieve changes in the top of the car, not only to meet the needs of daily driving and riding, but also to achieve space changes and multiple uses of one car, has become a research direction for automobiles.

[0038] Based on this, see Figure 3 As shown, the present application provides a sunroof assembly, including a movable panel 1, a rear windshield assembly 2 and a guide rail 3. The rear windshield assembly 2 is fixedly connected to the roof and is located behind the movable panel 1. The guide rail 3 is arranged along the length direction of the roof and at least extends to the rear windshield assembly 2; the movable panel 1 slides along the guide rail 3 to open and close the roof opening 4, the roof opening 4 is located above the passenger compartment 5, and the movable panel 1 can slide backward and cover the rear windshield assembly 2.

[0039] The utility model uses the rear windshield assembly 2 as a fixed plate, and the size of the movable plate 1 can completely cover the roof opening above the passenger compartment 5. Compared with the existing segmented panoramic sunroof, the size of the roof opening 4 above the passenger compartment 5 can be made larger, that is, when the movable plate is opened by sliding backward, the vertical space above the passenger compartment 5 can be completely connected with the outside of the vehicle, thereby increasing the vertical expansion function of the vehicle, which can better meet the user's use needs in multiple scenarios and realize the diversification of the roof function. In addition, since the movable plate 1 can slide backward and cover the rear windshield assembly 2, the movable plate 1 will not occupy the space inside the vehicle, and the layout is convenient and reasonable.

[0040] Optionally, the movable panel 1 is made of glass or other light-transmitting plastics. When the movable panel 1 is closed to shield the roof opening 4 , the lighting performance of the passenger compartment 5 in the vehicle is guaranteed.

[0041] In some embodiments of the present invention, see Figure 5 As shown, the rear windshield assembly 2 includes a rear windshield glass 21 and side trims 22 arranged on the left and right sides of the rear windshield glass 21, and a running channel for the movable panel 1 to slide backward and open is formed between the rear windshield glass 21 and the side trims 22. The overall appearance quality of the rear windshield assembly 2 is improved by the arrangement of the side trims 22. In addition, the space between the rear windshield glass 21 and the side trims 22 is used to form a running channel for the movable panel 1 to slide backward and open, which plays a guiding role in the sliding opening of the movable panel 1.

[0042] In some embodiments of the present invention, see Figure 6 As shown, a first sealing strip 8 is fixed to one side edge of the rear windshield 21 close to the side trim 22, and a second sealing strip 9 is fixed to one side edge of the side trim 22 close to the rear windshield 21, and the first sealing strip 8 and the second sealing strip 9 are abutted and sealed.

[0043] Due to the arrangement of the first sealing strip 8 and the second sealing strip 9, the appearance gap between the rear windshield 21 and the side trim 22 is sealed to isolate the air, rain, wind noise, etc. outside the vehicle. When the movable panel 1 slides backward, the connecting piece between the movable panel 1 and the guide rail 3 will open the first sealing strip 8 and the second sealing strip 9 to avoid affecting the opening of the movable panel 1. In addition, the first sealing strip 8 and the second sealing strip 9 are elastic. When the movable panel 1 slides, the first sealing strip 8 and the second sealing strip 9 can also contact the outer periphery of the connecting piece, which also plays a sealing role.

[0044] In some embodiments of the present invention, see Figure 6 As shown, the movable plate 1 is slidably connected to the guide rail 3 through a mechanical group 6, see Figure 8 As shown, the mechanical group 6 includes a support rod 61, an operating rod 62 and a slider 63. The support rod 61 is fixedly connected to the movable panel 1 with bolts, and the operating rod 62 is connected between the support rod 61 and the slider 63 to drive the movable panel 1 to tilt up. The slider 63 is slidably mounted to the guide rail 3, and is configured to drive the support rod 61 to move between a closed position and an open position, and to drive the operating rod 62 to move between a closed position and a tilted position. The mechanical group 6 is used to realize the tilting, opening and closing functions of the movable panel 1, and the structure is simple, stable and reliable.

[0045] See also Figure 6 and Figure 8 As shown, the front part of the slider 63 is fixedly engaged with the drive shaft 18, and the drive shaft 18 is connected to the drive motor 19 arranged at the rear part of the roof, and the drive motor 19 is connected to the power line plug of the vehicle body and energized. By controlling the drive motor 19 to rotate forward or reverse, the slider 63 moves forward and backward along the guide rail 3, thereby driving the support rod 61 to move between the closed position and the open position, and driving the operating rod 62 to move between the closed position and the tilted position.

[0046] In some embodiments of the present invention, see Figure 6 The sunroof assembly described in the present application also includes a roof frame 7 fixedly connected to the vehicle body 20 , and the rear windshield assembly 2 and the guide rail 3 are fixedly connected to the roof frame 7 .

[0047] See also Figure 7As shown, the roof frame 7 includes a front mounting portion 72, a middle mounting portion 73 and a rear mounting portion 74 which are arranged between two roof longitudinal beams 75 from front to rear. The front mounting portion 72, the middle mounting portion 73 and the rear mounting portion 74 are provided with a plurality of projection welding bolts for fixing the rear windshield assembly 2 or the guide rail 3. The periphery of the roof frame 7 is bonded to the periphery flange surface of the top of the vehicle body 20 by structural adhesive (not shown in the figure). The sunroof assembly is connected to the vehicle body 20 by bonding and bolting, which effectively ensures the connection strength between the sunroof assembly and the vehicle body 20.

[0048] In order to ensure the convenience of assembly, a safety gap is left between the sunroof assembly and the side wall of the vehicle body. By bonding the eighth sealing strip 71 around the roof frame 7, a sealing effect is achieved and the safety gap is shielded, thereby improving the NVH performance and appearance quality of the whole vehicle.

[0049] In order to ensure the sealing performance between the movable panel 1 and the roof frame 7 when the movable panel 1 is closed, a third sealing strip 10 is fixed on the roof frame 7 to correspond to the outer edge of the movable panel.

[0050] Since a safety gap is left between the rear side of the movable panel 1 and the front side of the rear windshield assembly 2, in order to ensure the sealing performance between the two, a fourth sealing strip 11 corresponding to the rear side of the movable panel 1 is fixed to the front side of the rear windshield assembly 2. At the same time, in order to ensure the sealing performance between the front side of the rear windshield assembly 2 and the roof frame 7, a fifth sealing strip 12 is arranged between the roof frame 7 and the front side of the windshield assembly 2.

[0051] Optionally, a front trim panel 16 is arranged between the movable panel 1 and the front windshield 30, and a rear trim panel 17 is arranged at the rear end of the rear windshield assembly 2. The arrangement of the front trim panel 16 and the rear trim panel 17 serves as a transition decoration, thereby improving the overall appearance quality of the roof.

[0052] Since safety gaps are left between the rear side of the front trim panel 16 and the front side of the movable panel 1 , and between the front side of the rear trim panel 17 and the rear side of the rear windshield assembly 2 , in order to ensure the sealing performance of the roof, a sixth sealing strip 13 is clamped and fixed to the rear side of the front trim panel 16 , and a seventh sealing strip 14 is clamped and fixed to the front side of the rear trim panel.

[0053] In some embodiments of the present invention, see Figure 6 As shown, the sunroof assembly described in the present application also includes a windshield assembly 15 arranged at the lower front portion of the movable panel 1 and capable of being raised and lowered. When the movable panel 1 is lifted up or slid backward to open, the windshield assembly 15 is raised and in an open state; when the movable panel 1 is closed to shield the passenger compartment area, the windshield assembly 15 is lowered and in a closed state.

[0054] In some embodiments of the present invention, see Fig.11As shown, the roof frame 7 and the roof opening 4 are provided with a plurality of mounting components in the corresponding areas, and the expansion assembly 50 is fixedly installed by the mounting components.

[0055] In daily use:

[0056] Usage scenario 1: receiving the sunroof assembly tilting instruction, the drive motor 19 starts to work, drives the slider 63 of the mechanical group 6 to start sliding backward through the drive shaft 18, and drives the control lever 62 to move from the closed position to the tilting position, see Fig. 9 As shown, the roof movable panel 1 is lifted and opened, thereby realizing the circulation of air inside and outside the vehicle, meeting the requirements of lighting, exhaust and cooling inside the vehicle during the use of the vehicle. In addition, when the movable panel 1 is lifted and opened, the windshield assembly 15 is opened synchronously, thereby shielding the front wind when the vehicle is driving, avoiding the noise and bad driving experience caused by the external wind blowing into the vehicle, and shielding foreign objects outside the vehicle to protect the safety of passengers.

[0057] Usage scenario 2: After receiving the sunroof assembly opening command, the drive motor 19 starts to work, drives the slider 63 of the mechanical group 6 to start sliding backward through the drive shaft 18, drives the support rod 61 to move from the closed position to the open position, and then drives the movable panel 1 to move backward to the open position. Fig.10 As shown, the roof opening 4 is fully opened, and the front and rear spaces of the vehicle passenger compartment 5 are connected to the outside of the vehicle, so that all passengers in the passenger compartment 5 have perfect ventilation, air permeability and top vision. It should be noted that according to the use requirements of the front and rear space, the movable panel 1 can be opened and suspended to any position above the rear windshield assembly 2 by operating the opening switch, so that the vertical space on the roof is released. Under the premise of meeting the normal lighting, ventilation and vehicle heat dissipation requirements, it can also meet the user's needs for vertical space expansion in driving or loading scenarios.

[0058] Use scenario three: See Fig.11 As shown, the movable panel 1 is fully opened and hovers above the rear windshield assembly 2, which can meet the vertical space expansion in the camping scene. According to the needs, mosquito nets, tents and other expansion components 50 are added and fixed on the roof frame 7 or the side of the vehicle body, so as to obtain a spacious cabin space. In this state, the movable panel 1 is in an open state and slides completely above the rear windshield assembly 2. The vertical space above the passenger cabin is completely connected with the outside of the vehicle, which can meet the needs of installing tents, mosquito nets and other facilities on the roof in the camping scene. With the folding seats and vehicle-mounted inflatable mattresses in the cabin, the passengers can freely realize the scene requirements of sitting, lying, standing, etc. in the car.

[0059] Use scenario 4: See Figure 3As shown, after receiving the closing instruction of the sunroof assembly, the movable panel 1 is completely closed, and an integral panoramic roof is formed with the rear windshield assembly 2, so that the entire passenger compartment 5 has a completely transparent effect and a top view. In this state, the sunroof assembly is in a closed state, and the upper vertical space is enclosed by the movable panel 1. When the movable panel 1 is made of glass, it can also meet the lighting needs of users in driving or in-car activities. Since the movable panel 1 and the rear windshield glass 21 of the rear windshield assembly 2 are both light-transmissive, the needs of passengers for external light, top view and rear view when using the front and rear spaces can be met.

[0060] See also Figure 3 As shown, the utility model also provides a vehicle, which includes the sunroof assembly described in any one of the above items.

[0061] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto.
