Technical Field

[0001] The utility model relates to the technical field of automobile assembly, and particularly relates to a fixing structure for an automobile ceiling. In addition, the utility model also relates to an automobile. Background Art

[0002] In the overall structure of an automobile, an automobile ceiling is provided at the top of the cockpit. The automobile ceiling is usually hoisted on the roof frame by means of snap connection, welding, bonding, etc. However, in the relatively empty area in the middle of the automobile ceiling, since the automobile ceiling is a thin-walled structure, it is prone to sag due to its own weight. Therefore, a certain connection structure needs to be provided between the middle of the automobile ceiling and the roof frame to ensure the structural stability of the middle of the automobile ceiling.

[0003] However, the connection structure located in the middle of the automobile ceiling is to be arranged on the back of the automobile ceiling and hidden between the automobile ceiling and the roof frame, which is not convenient for observation and operation. When directly adopting a snap structure, due to the influence of the tolerances of the components, it is easy to have a situation where it is difficult to align, resulting in difficult plug-in snap connection operation. At the same time, since there is a certain interval space between the automobile ceiling and the roof frame, when adopting the bonding method, some cushion components need to be added, which not only makes the structural arrangement cumbersome, but also has the problem of poor bonding firmness. Summary of the Utility Model

[0004] In view of this, the utility model aims to propose a fixing structure for an automobile ceiling to improve the assembly convenience of the automobile ceiling on the roof frame.

[0005] To achieve the above object, the technical solution of the utility model is realized as follows:

[0007] With the installation of the automobile ceiling in place on the roof frame, the mushroom snap fastener on the ceiling connection seat engages with the corresponding mushroom snap fastener on the sheet metal connection seat to form a fixed connection between the automobile ceiling and the roof frame.

[0008] Further, a sheet metal arranged along the left-right direction of the automobile is provided in the roof frame, and a plurality of the sheet metal connection seats are arranged at intervals on the sheet metal. Corresponding to each of the sheet metal connection seats, a plurality of the ceiling connection seats are provided on the automobile ceiling.

[0009] Further, on the corresponding ceiling connecting seat and the sheet metal connecting seat, the length dimension of the mushroom snap provided on the ceiling connecting seat is greater than the length dimension of the mushroom snap provided on the sheet metal connecting seat, and the width dimension of the mushroom snap provided on the ceiling connecting seat is greater than the width dimension of the mushroom snap provided on the sheet metal connecting seat.

[0010] Further, the length dimension ratio and the width dimension ratio of the mushroom snaps on the corresponding ceiling connecting seat and the sheet metal connecting seat are both between 1.2 and 1.8.

[0011] Further, the ceiling connecting seat includes a chassis and a connecting platform protruding from the middle of the chassis; the mushroom snap is provided on the top of the connecting platform, and the side of the chassis facing away from the connecting platform is fixedly connected to the automobile ceiling.

[0012] Further, the chassis and the automobile ceiling are adhesively and fixedly connected.

[0013] Further, reinforcing ribs are formed on the side of the connecting platform and extend towards the chassis and are connected to the chassis.

[0014] Further, the sheet metal connecting seat includes a connecting plate and a clamping head provided in the middle of the connecting plate; the mushroom snap is provided on the side of the connecting plate facing away from the clamping head, and the sheet metal connecting seat is clamped on the vehicle roof frame through the clamping head.

[0015] Further, a soft pad is provided on the connecting plate and arranged around the clamping head. As the sheet metal connecting seat is clamped on the vehicle roof frame, the soft pad is clamped between the connecting plate and the vehicle roof frame.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] For the automobile ceiling fixing structure of the present invention, by pre-installing the sheet metal connecting seat on the vehicle roof frame and pre-installing the ceiling connecting seat on the automobile ceiling, the installation and fixation between the ceiling connecting seat and the automobile ceiling can be conveniently realized by using the mushroom snaps provided on the ceiling connecting seat and the sheet metal connecting seat; since during the process of buckling the automobile ceiling onto the vehicle roof frame, the installation structure between the automobile ceiling and the vehicle roof frame is in an invisible area and is not convenient to observe, by pre-correspondingly setting the ceiling connecting seat and the sheet metal connecting seat and using the mushroom snaps provided on both to realize snap connection, the installation operation of the automobile ceiling on the vehicle roof frame is made simpler and more convenient, thereby improving the assembly convenience of the automobile ceiling on the vehicle roof frame.

[0018] At the same time, using the mushroom snap for connection is more firm than the traditional colloid bonding, and the installation is convenient, which is conducive to saving installation man-hours.

[0019] In addition, in order to address the situation where the corresponding roof connecting seat and sheet metal connecting seat may be relatively offset and cannot be completely aligned due to the tolerance of the components themselves when assembling the car roof, the mushroom buckle on the roof connecting seat is designed to be larger. This can ensure that the entire area of ​​the mushroom buckle on the sheet metal connecting seat can achieve an engagement connection with the mushroom buckle on the ceiling connecting seat, thereby effectively protecting the bonding area of ​​the mushroom buckle.

[0020] Another object of the utility model is to provide a car, wherein the car roof fixing structure of the utility model is arranged between the car roof and the car roof frame.

[0041] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0042] Embodiment 1

[0043] This embodiment relates to a fixing structure for an automobile ceiling, which can improve the assembly convenience of the automobile ceiling 1 on the roof frame; an exemplary structure thereof is as shown in Figure 1 , Figure 2 and Figure 3 .

[0044] Generally speaking, the fixing structure for the automobile ceiling includes a sheet metal connection seat 4 pre-installed on the roof frame, and a ceiling connection seat 3 provided on the automobile ceiling 1 corresponding to the sheet metal connection seat 4, and mushroom fasteners 5 are respectively provided on the ceiling connection seat 3 and the sheet metal connection seat 4. As the automobile ceiling 1 is installed in place on the roof frame, the mushroom fastener 5 on the ceiling connection seat 3 engages with the mushroom fastener 5 on the corresponding sheet metal connection seat 4 to form a fixed connection between the automobile ceiling 1 and the roof frame.

[0045] It should be noted that based on the above overall design concept, the technical solutions of the present utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, a pair or multiple pairs of the above-mentioned oppositely arranged ceiling connection seats 3 and sheet metal connection seats 4 can be provided, and the positions and arrangement methods thereof provided on the automobile ceiling 1 can also be flexibly selected; the ceiling connection seat 3 and the sheet metal connection seat 4 can be integrally formed with a metal material or a plastic material. For the parts required for the implementation of the overall solution but not involved in the above overall setting, reasonable and flexible designs can be made with reference to the mature setting means in the art, the actual situation during implementation, etc. The following specific implementation solutions of this embodiment are only one of the better ones among the many solutions that can be formed by the above various combinations and their variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements in combination with the actual situation. Obviously, the many solutions that can be formed by the above various specific forms of combinations and their variations, as well as the specific implementation solutions of this embodiment, are all within the protection scope of the present utility model.

[0046] Specifically, in this embodiment, a sheet metal 20 arranged along the left-right direction of the car is provided in the roof frame, and a plurality of sheet metal connection seats 4 are arranged at intervals on the sheet metal 20, and a plurality of roof connection seats 3 are arranged on the car roof 1 corresponding to each sheet metal connection seat 4. A plurality of sheet metal connection seats 4 are arranged at intervals on the beam-shaped sheet metal 20 placed horizontally in the roof frame, so that a multi-point connection and fixation can be formed between the sheet metal 20 and the car roof 1, thereby forming a good support and fixation for the car roof 1, and improving the assembly stability of the car roof 1.

[0047] The sizes of the two mushroom buckles 5 on the ceiling connection seat 3 and the sheet metal connection seat 4 can be flexibly set; they can be of the same size or different sizes. Figures 4 to 7 As shown, on the corresponding ceiling connecting seat 3 and sheet metal connecting seat 4, the length dimension of the mushroom buckle 5 arranged on the ceiling connecting seat 3 is greater than the length dimension of the mushroom buckle 5 arranged on the sheet metal connecting seat 4, and the width dimension of the mushroom buckle 5 arranged on the ceiling connecting seat 3 is greater than the width dimension of the mushroom buckle 5 arranged on the sheet metal connecting seat 4.

[0048] The size ratio of the two mushroom buckles 5 on the ceiling connection seat 3 and the sheet metal connection seat 4 can be reasonably set within an appropriate range. Preferably, the length and width ratios of the mushroom buckles 5 on the corresponding ceiling connection seat 3 and the sheet metal connection seat 4 are both between 1.2 and 1.8. Figure 7 As shown in , the length L1 and width W1 of the mushroom buckle 5 on the ceiling connection seat 3, and the length L2 and width W2 of the mushroom buckle 5 on the sheet metal connection seat 4 satisfy: L1 / L2=W1 / W2=1.2-1.8. Of course, the mushroom buckle 5 can be in a regular shape such as a rectangle, square or circle, or an irregular shape, and the size ratio can be set according to the above ratio.

[0049] In order to solve the problem that the corresponding roof connecting seat 3 and the sheet metal connecting seat 4 may be relatively offset and cannot be completely aligned due to the tolerance of the components themselves when assembling the automobile roof 1, the mushroom buckle 5 on the roof connecting seat 3 is designed to be larger, which can ensure that the entire area of ​​the mushroom buckle 5 on the sheet metal connecting seat 4 can achieve an engagement connection with the mushroom buckle 5 on the roof connecting seat 3, thereby effectively ensuring the bonding area of ​​the mushroom buckle 5.

[0050] Moreover, during the assembly process of the automotive roof lining 1, it is not convenient to observe and adjust the alignment of the roof connecting seat 3 and the sheet metal connecting seat 4 located on the back of the automotive roof lining 1. The mushroom snap fasteners 5 on the roof connecting seat 3 and the sheet metal connecting seat 4 are designed with different sizes. The mushroom snap fastener 5 with a smaller area is used as the lower limit of the connection performance, which can ensure that it is firmly adhered. It should be noted here that the adhesion between the two mushroom snap fasteners 5 is actually achieved by the mutual clamping and engagement of the mushroom heads 51 on the two mushroom snap fasteners 5. Generally speaking, the mushroom snap fastener 5 includes a base layer 50 and a plurality of mushroom heads 51 densely arranged on the base layer 50. The mushroom head 51 includes a head 510 and a neck 511 connecting the head 510 and the base layer 50. On the side of the base layer 50 facing away from the mushroom head 51, a back adhesive layer 52 and a release paper are usually provided.

[0051] Combined Figures 8 to 11 As shown, in this embodiment, after the release paper of the mushroom snap fastener 5 is removed, it is adhered to the roof connecting seat 3 or the sheet metal connecting seat 4 by using the back adhesive layer 52. When the roof connecting seat 3 and the sheet metal connecting seat 4 are docked, the head 510 of the mushroom head 51 of the mushroom snap fastener 5 on the roof connecting seat 3 will be inserted between the mushroom heads 51 of the mushroom snap fastener 5 on the sheet metal connecting seat 4, and the heads 510 will bite and block each other, making it difficult to separate the two adhered mushroom snap fasteners 5. After the mushroom snap fasteners 5 on the roof connecting seat 3 and the sheet metal connecting seat 4 are connected by the engagement of the mushroom heads 51, they can withstand the pressure and tension between the automotive roof lining 1 and the roof frame.

[0052] For the specific structural forms of the roof connecting seat 3 and the sheet metal connecting seat 4, of course, there are many different structural schemes to choose from. In this embodiment, as Figure 4 shown, the roof connecting seat 3 includes a chassis 30 and a connecting platform 31 protruding from the middle of the chassis 30. The mushroom snap fastener 5 is provided on the top of the connecting platform 31, and the side of the chassis 30 facing away from the connecting platform 31 is fixedly connected to the automotive roof lining 1. Based on the fact that the automotive roof lining 1 is a thin-walled structure, the roof connecting seat 3 is designed in the form of the chassis 30 and the connecting platform 31. The chassis 30 is fixedly connected to the automotive roof lining 1, which can increase the contact area between the automotive roof lining 1 and the roof connecting seat 3, thereby increasing the connection stability between the roof connecting seat 3 and the automotive roof lining 1. The connection method between the automotive roof lining 1 and the roof connecting seat 3 is preferably an adhesive fixing method, that is, the chassis 30 is adhesively fixed to the automotive roof lining 1.

[0053] In addition, a reinforcing rib 32 is formed on the side of the connecting platform 31 in this embodiment. The reinforcing rib 32 extends towards the chassis 30 and is connected to the chassis 30. By providing the reinforcing rib 32 on the side of the connecting platform 31 and extending the reinforcing rib 32 down to the chassis 30, it is beneficial to increase the structural support strength of the connecting platform 31.

[0054] AsFigure 5 and Figure 6 As shown in Figure 6 , the sheet metal connecting seat 4 of this embodiment includes a connecting plate 40 and a chuck 41 provided in the middle of the connecting plate 40; and the mushroom buckle 5 is arranged on the side of the connecting plate 40 facing away from the chuck 41. The sheet metal connecting seat 4 is clamped on the roof frame through the chuck 41. By designing the chuck 41 on the sheet metal connecting seat 4 and inserting the chuck 41 into the clamping hole 200 opened in the sheet metal 20, the installation method is not only convenient and efficient, but also has firm connection.

[0055] Based on the above settings, a soft pad 42 is arranged on the connecting plate 40 of this embodiment around the chuck 41. As the sheet metal connecting seat 4 is clamped on the roof frame, the soft pad 42 is clamped between the connecting plate 40 and the roof frame. Arranging the soft pad 42 on the connecting plate 40 can play a good buffering and supporting role between the connecting plate 40 and the sheet metal 20, and can effectively prevent the sheet metal connecting seat 4 from loosening on the automotive ceiling 1.

[0056] In summary, for the automotive ceiling fixing structure of this embodiment, by pre-installing the sheet metal connecting seat 4 on the roof frame and pre-installing the ceiling connecting seat 3 on the automotive ceiling 1, the mushroom buckles 5 provided on the ceiling connecting seat 3 and the sheet metal connecting seat 4 can be used to conveniently realize the installation and fixation between the ceiling connecting seat 3 and the automotive ceiling 1; since during the process of buckling the automotive ceiling 1 onto the roof frame, the installation structure between the automotive ceiling 1 and the roof frame is in an invisible area and is not convenient to observe, by pre-correspondingly setting the ceiling connecting seat 3 and the sheet metal connecting seat 4 and using the mushroom buckles 5 provided on both of them to achieve snap connection, the installation operation of the automotive ceiling 1 on the roof frame is made simpler and more convenient, thereby improving the assembly convenience of the automotive ceiling 1 on the roof frame.

[0057] Embodiment 2

[0058] This embodiment relates to an automobile, and the automotive ceiling 1 and the roof frame of the automobile adopt the automotive ceiling fixing structure provided in Embodiment 1.

[0059] By adopting the automotive ceiling fixing structure of the present utility model, the problem of difficult assembly caused by the installation points on the automotive ceiling 1 being arranged in an invisible area in the traditional design is solved. Moreover, the ceiling connecting seat 3 and the sheet metal connecting seat 4 are bonded through the mushroom buckle 5, which is more firm than the traditional colloid bonding method, is convenient for installation, and saves the total installation man-hours of the automotive ceiling 1 on the roof frame.

[0060] The above are only the preferred embodiments of the present utility model. The explanations of the detailed configuration, the examples of specific structural settings, or the descriptions of the assembly and connection methods are all for the need of full disclosure, so that those skilled in the art can better implement the present utility model, rather than to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
