Description

Technical Field

[0001] This invention relates to the field of automotive technology, specifically to a connection structure between a side panel assembly and a panoramic sunroof, and an automobile thereof. Background Technology

[0002] Panoramic sunroofs on cars are significantly larger than regular sunroofs, offering an exceptionally wide field of vision. The reinforcing ring within the panoramic sunroof and its connection to the car body are crucial structural elements of the roof.

[0003] Currently, panoramic sunroofs are mounted on reinforcing rings, which are connected to the side panel welding assembly by applying structural adhesive or welding. A bracket is added between the reinforcing ring and the side panel welding assembly to strengthen the connection between them.

[0004] However, the bracket is only connected to the B-pillar inner panel reinforcement in the side panel welding assembly. The B-pillar inner panel reinforcement is not a key component for improving collision performance. Due to weight reduction considerations, it is usually thinner, resulting in insufficient support from the side panel welding assembly for the bracket. Summary of the Invention

[0005] One objective of this invention is to provide a connection structure between the side panel assembly and the panoramic sunroof, so as to solve the technical problem that the side panel welded assembly does not provide sufficient support for the bracket in the prior art; the second objective is to provide an automobile.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A connection structure between a side panel assembly and a panoramic sunroof includes a panoramic sunroof, a sunroof reinforcing ring, a final assembly bracket, and a side panel assembly. The final assembly bracket is connected to the sunroof reinforcing ring and the panoramic sunroof.

[0008] The side panel assembly includes an upper inner plate reinforcement member for the B-pillar and an inner plate for the B-pillar. The assembly bracket forms a three-layer connection structure with the upper inner plate reinforcement member for the B-pillar and the inner plate for the B-pillar.

[0009] Based on the aforementioned technical means, the three-layer connection structure formed by the general assembly bracket, the inner panel reinforcement of the B-pillar, and the inner panel of the B-pillar enhances the support performance of the side assembly to the general assembly bracket and improves the connection performance of the sunroof reinforcement ring to the side assembly through the general assembly bracket, thus solving the technical problem of insufficient support of the side welding assembly to the bracket. In addition, the general assembly bracket is connected to both the sunroof reinforcement ring and the panoramic sunroof, meaning that the general assembly bracket will be directly connected to the panoramic sunroof. This increases the force transmission path from the panoramic sunroof to the side assembly, improves the bending and torsional performance of the vehicle, and can also effectively suppress the excitation generated by the road surface on the vehicle, so that the panoramic sunroof and the vehicle can be frequency coupled, reducing the discomfort of ear pressure for passengers.

[0010] Furthermore, the assembly bracket has multiple first mounting holes, the inner plate of the B column is welded to the upper inner plate reinforcement of the B column, the inner plate of the B column includes a connecting part, the connecting part has multiple second mounting holes corresponding to the multiple first mounting holes, the upper inner plate reinforcement of the B column has multiple third mounting holes corresponding to the multiple first mounting holes, and the first mounting holes, the second mounting holes and the third mounting holes are connected by first mounting bolts.

[0011] According to the above technical means, the connection of the first mounting hole, the second mounting hole and the third mounting hole through the first mounting bolt can realize the bolted connection of the three-layer connection structure of the general assembly bracket, the inner plate reinforcement of the B column and the inner plate of the B column.

[0012] Furthermore, the assembly bracket has a fourth mounting hole, the panoramic sunroof has a fifth mounting hole corresponding to the fourth mounting hole, and the sunroof reinforcing ring has a sixth mounting hole corresponding to the fourth mounting hole. The fourth mounting hole, the fifth mounting hole, and the sixth mounting hole are connected by a second mounting bolt.

[0013] Based on the aforementioned technical means, the assembly bracket is connected to the panoramic sunroof and the sunroof reinforcing ring by means of the fourth mounting hole, the fifth mounting hole and the sixth mounting hole and the second mounting bolt.

[0014] Furthermore, the assembly bracket has a seventh mounting hole, and the sunroof reinforcing ring has an eighth mounting hole corresponding to the seventh mounting hole. The seventh mounting hole and the eighth mounting hole are connected by a third mounting bolt.

[0015] Based on the aforementioned technical means, the connection between the main assembly bracket and the sunroof reinforcing ring is achieved by connecting the seventh and eighth mounting holes with the third mounting bolt; and by connecting the main assembly bracket, panoramic sunroof, and sunroof reinforcing ring together with the second mounting bolt, the connection performance between the main assembly bracket and the sunroof reinforcing ring is guaranteed.

[0016] Furthermore, the inner plate of the B column has an upper boundary that extends to the first mounting hole on the assembly bracket. The upper boundary is located between the assembly bracket and the inner plate reinforcement of the B column, and the bottom of the assembly bracket covers the upper boundary.

[0017] Based on the above technical means, it is ensured that the inner panel of column B has a part that overlaps with the final assembly bracket, thereby facilitating the connection between the inner panel of column B and the final assembly bracket.

[0018] Furthermore, the sunroof reinforcing ring is welded to the inner plate reinforcing member of the B column.

[0019] The above-mentioned technical means ensure the connection performance between the sunroof reinforcing ring and the inner panel reinforcing member of the B pillar.

[0020] Furthermore, the connecting part is located between the final assembly bracket and the inner plate reinforcement of the B column, with the inner plate reinforcement of the B column located on the lower layer, the inner plate of the B column located on the middle layer, and the final assembly bracket located on the upper layer.

[0021] Based on the above technical means, the assembly bracket, the inner plate of the B column, and the upper inner plate reinforcement of the B column form a three-layer structure, which facilitates the connection of the three-layer structure.

[0022] Furthermore, the panoramic sunroof is located on the outer layer, the assembly bracket is located on the middle layer, and the sunroof reinforcing ring is located on the inner layer.

[0023] Based on the aforementioned technical means, it is easy to simultaneously connect the panoramic sunroof, the main assembly bracket, and the sunroof reinforcing ring through a single installation point.

[0024] An automobile, the automobile including the connection structure between the side panel assembly and the panoramic sunroof as described in any of the preceding claims.

[0025] Beneficial effects of the embodiments of the present invention:

[0026] In this embodiment of the invention, the three-layer connection structure formed by the assembly bracket, the inner panel reinforcement of the B-pillar, and the inner panel of the B-pillar enhances the support performance of the side assembly to the assembly bracket and improves the connection performance of the sunroof reinforcement ring to the side assembly through the assembly bracket. This solves the technical problem of insufficient support of the side welded assembly to the bracket. In addition, the assembly bracket is connected to both the sunroof reinforcement ring and the panoramic sunroof, meaning that the assembly bracket will be directly connected to the panoramic sunroof. This increases the force transmission path from the panoramic sunroof to the side assembly, improves the bending and torsional performance of the vehicle, and can also effectively suppress the excitation generated by the road surface on the vehicle, so that the panoramic sunroof and the vehicle can be frequency coupled, reducing the discomfort of ear pressure for passengers.

Detailed Implementation

[0034] The embodiments of the present invention will be described below 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 content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed 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 and 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 representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0036] Currently, referring to Figure 1 This diagram illustrates the connection structure between the existing side panel welding assembly and the panoramic sunroof 1. The panoramic sunroof 1 is mounted on a reinforcing ring 2, which is connected to the side panel welding assembly by applying structural adhesive or welding. A bracket 4 is added between the reinforcing ring 2 and the side panel welding assembly to strengthen the connection. The B-pillar inner panel 5 is welded to the B-pillar upper inner panel reinforcement 3, and the reinforcing ring 2 is also welded to the B-pillar upper inner panel reinforcement 3. The bracket 4 is connected to the B-pillar upper inner panel reinforcement 3 and the reinforcing ring 2 by four mounting bolts. The panoramic sunroof 1 is connected to the reinforcing ring 2 by eighteen mounting bolts.

[0037] However, this connection method has the following problems: The bracket 4 only connects the side panel welded assembly and the reinforcing ring 2. This causes the panoramic sunroof 1 to vibrate when the vehicle is subjected to road surface excitation. The resulting force is transmitted through the reinforcing ring 2 to the bracket 4 and the side panel welded assembly. This places high demands on the strength of the reinforcing ring 2 components, meaning the material thickness of the reinforcing ring 2 cannot be too thin, resulting in a heavier component, which is detrimental to vehicle lightweighting. Furthermore, when the bracket 4 connects to the side panel welded assembly, it only connects to the B-pillar inner panel reinforcement 3. Since the B-pillar inner panel reinforcement 3 is not a key component for improving collision performance, it is usually thinner for lightweighting purposes. This results in insufficient support from the side panel welded assembly for the bracket 4. Therefore, we propose a connection structure between the side panel assembly and the panoramic sunroof, and a vehicle to solve the above problems.

[0038] Firstly, referring to Figures 2 to 6 This invention proposes a connection structure between a side panel assembly and a panoramic sunroof. 1. A panoramic sunroof 10, a sunroof reinforcing ring 20, a final assembly bracket 40, and a side panel assembly. The final assembly bracket 40 is connected to the sunroof reinforcing ring 20 and the panoramic sunroof 10. The side panel assembly includes an inner plate reinforcing member 30 on the B-pillar and an inner plate 50 on the B-pillar. The final assembly bracket 40, the inner plate reinforcing member 30 on the B-pillar, and the inner plate 50 on the B-pillar form a three-layer connection structure.

[0039] Specifically, the connection between the final assembly bracket 40 and the sunroof reinforcing ring 20 can be a screw connection. The connection between the final assembly bracket 40 and the panoramic sunroof 10 can also be a screw connection. The connection between the three-layer structure formed by the final assembly bracket 40, the B-pillar upper inner plate reinforcing member 30, and the B-pillar inner plate 50 can also be a screw connection. The B-pillar upper inner plate reinforcing member 30 is welded to the B-pillar inner plate 50.

[0040] In this embodiment of the invention, the three-layer connection structure formed by the final assembly bracket 40, the inner plate reinforcement 30 of the B-pillar, and the inner plate 50 of the B-pillar enhances the support performance of the side assembly to the final assembly bracket 40 and improves the connection performance of the sunroof reinforcing ring 20 to the side assembly through the final assembly bracket 40, thus solving the technical problem of insufficient support from the side welding assembly to the final assembly bracket. Furthermore, the final assembly bracket 40 is connected to both the sunroof reinforcing ring 20 and the panoramic sunroof 10, meaning that the final assembly bracket 40 will directly connect to the panoramic sunroof 10. The connection increases the force transmission path from the panoramic sunroof 10 to the side assembly, improving the vehicle's bending and torsional performance. It also effectively suppresses the excitation generated by the road surface on the vehicle, allowing the panoramic sunroof to couple with the vehicle's frequency and reducing discomfort for passengers. In addition, since the final assembly bracket 40 is connected to both the sunroof reinforcing ring 20 and the panoramic sunroof 10, the strength requirements for the sunroof reinforcing ring 20 are reduced. The material thickness of the sunroof reinforcing ring 20 can be thinner, thereby reducing its weight and contributing to the vehicle's lightweight design.

[0041] Reference Figure 3 and Figure 4 The assembly bracket 40 has multiple first mounting holes 41. The inner plate 50 of the B column is welded to the upper inner plate reinforcement 30 of the B column. The inner plate 50 of the B column includes a connecting part 52. The connecting part 52 has multiple second mounting holes 521 corresponding to the multiple first mounting holes 41. The upper inner plate reinforcement 30 of the B column has multiple third mounting holes corresponding to the multiple first mounting holes 41. The first mounting holes 41, the second mounting holes 521 and the third mounting holes are connected by first mounting bolts.

[0042] Specifically, the connecting part 52 is the portion on the inner plate 50 of the B-post that overlaps with the assembly bracket 40. The bottom of the assembly bracket 40 can have two first mounting holes 41. The connecting part 52 is located at the very top of the inner plate 50 of the B-post, and has two second mounting holes 521. The two first mounting holes 41 correspond to the two second mounting holes 521. The inner plate reinforcement 30 of the B-post has two third mounting holes.

[0043] In this embodiment of the invention, the connection of the first mounting hole 41, the second mounting hole 521 and the third mounting hole through the first mounting bolt can realize the screw connection of the three-layer connection structure of the general assembly bracket 40, the inner plate reinforcement 30 of the B column and the inner plate of the B column 50.

[0044] Reference Figures 4 to 6 The assembly bracket 40 has a fourth mounting hole, the panoramic sunroof 10 has a fifth mounting hole corresponding to the fourth mounting hole, and the sunroof reinforcing ring 20 has a sixth mounting hole corresponding to the fourth mounting hole. The fourth mounting hole, the fifth mounting hole, and the sixth mounting hole are connected by the second mounting bolt 60.

[0045] Specifically, the main assembly bracket 40, the panoramic sunroof 10, and the sunroof reinforcing ring 20 are connected together by the second mounting bolt 60. That is, the main assembly bracket 40 is connected to both the second mounting bolt 60 and the sunroof reinforcing ring 20 via the second mounting bolt 60. In this embodiment of the invention, the connection between the main assembly bracket 40 and the panoramic sunroof 10 and the sunroof reinforcing ring 20 is achieved by connecting the fourth, fifth, and sixth mounting holes via the second mounting bolt 60.

[0046] Reference Figure 4 and Figure 5 The assembly bracket 40 has a seventh mounting hole, and the sunroof reinforcing ring 20 has an eighth mounting hole corresponding to the seventh mounting hole. The seventh mounting hole and the eighth mounting hole are connected by the third mounting bolt 70.

[0047] Specifically, the assembly bracket 40 and the sunroof reinforcing ring 20 can be connected together by the third mounting bolt 70. In this embodiment of the invention, the connection between the seventh mounting hole and the eighth mounting hole via the third mounting bolt 70 achieves the screw connection between the assembly bracket 40 and the sunroof reinforcing ring 20; and while the assembly bracket 40, the panoramic sunroof 10, and the sunroof reinforcing ring 20 are connected together by the second mounting bolt 60, the connection performance between the assembly bracket 40 and the sunroof reinforcing ring 20 is ensured.

[0048] Reference Figure 3 The inner plate 50 of column B has an upper boundary 51 that extends upward to the first mounting hole 41 on the assembly bracket 40. The upper boundary 51 is located between the assembly bracket 40 and the inner plate reinforcement 30 of column B, and the bottom of the assembly bracket 40 covers the upper boundary 51. In this embodiment of the invention, the above arrangement ensures that the inner plate 50 of column B has a portion that overlaps with the assembly bracket 40, thereby facilitating the connection between the inner plate 50 of column B and the assembly bracket 40.

[0049] The sunroof reinforcing ring 20 is welded to the inner plate reinforcing member 30 on the B pillar, ensuring the connection performance between the sunroof reinforcing ring 20 and the inner plate reinforcing member 30 on the B pillar.

[0050] The connecting part 52 is located between the final assembly bracket 40 and the inner plate reinforcement 30 of the B column. The inner plate reinforcement 30 of the B column is located in the lower layer, the inner plate 50 of the B column is located in the middle layer, and the final assembly bracket 40 is located in the upper layer. In this embodiment of the invention, the inner plate reinforcement 30 of the B column is located in the lower layer, the inner plate 50 of the B column is located in the middle layer, and the final assembly bracket 40 is located in the upper layer, so that the final assembly bracket 40, the inner plate 50 of the B column, and the inner plate reinforcement 30 of the B column form a three-layer structure of upper, middle, and lower, which facilitates the connection of the three-layer structure.

[0051] The panoramic sunroof 10 is located on the outer layer, the assembly bracket 40 is located on the middle layer, and the sunroof reinforcing ring 20 is located on the inner layer. In this embodiment of the invention, the panoramic sunroof 10 is located on the outer layer, the assembly bracket 40 is located on the middle layer, and the sunroof reinforcing ring 20 is located on the inner layer, so that the mounting points of the panoramic sunroof 10, the assembly bracket 40, and the sunroof reinforcing ring 20, that is, the mounting positions of the second mounting bolt 60, are three layers, thereby facilitating the simultaneous connection of the panoramic sunroof 10, the assembly bracket 40, and the sunroof reinforcing ring 20 through a single mounting point.

[0052] In summary, in this embodiment of the invention, the inner plate 50 of the B-pillar is connected to the upper inner plate reinforcement 30 of the B-pillar by welding, and the sunroof reinforcement ring 20 is connected to the upper inner plate reinforcement 30 of the B-pillar by welding. A general assembly bracket 40 is provided between the sunroof reinforcement ring 20 and the inner plate 50 of the B-pillar. The general assembly bracket 40 is connected to the upper inner plate reinforcement 30 of the B-pillar, the sunroof reinforcement ring 20, the inner plate 50 of the B-pillar, and the panoramic sunroof 10 by four bolts. The panoramic sunroof 10 is connected to the sunroof reinforcement ring 20 by eighteen bolts. Figure 3 As shown, compared to the current technology, the upper boundary 51 extends upwards.

[0053] The working principle of the connection structure between the side panel assembly and the panoramic sunroof provided in this embodiment of the invention is as follows: In this connection structure, the upper boundary 51 of the inner plate 50 of the B-pillar is moved upward and overlaps with the assembly bracket 40, forming a three-layer connection at the overlap: the inner plate reinforcement 30 of the B-pillar is at the bottom layer, the inner plate 50 of the B-pillar is in the middle layer, and the assembly bracket 40 is at the top layer. In addition, the material of the assembly bracket 40 is enlarged and connected with the sunroof reinforcing ring 20 to create one mounting point. At the same time, the assembly bracket 40 is connected together with the panoramic sunroof 10 and the sunroof reinforcing ring 20 to create another mounting point.

[0054] With this optimization, the connection between the panoramic sunroof 10 and the side assembly is improved. Compared with the existing technology, the assembly bracket 40 will be directly connected to the panoramic sunroof 10, which increases the force transmission path from the panoramic sunroof 10 to the side assembly, improves the bending and torsional performance of the whole vehicle, and can also effectively suppress the excitation generated by the road surface on the vehicle, so that the panoramic sunroof 10 and the vehicle can be coupled at the same frequency, reducing the discomfort of ear pressure for passengers.

[0055] It is understood that the above examples are merely examples listed to better understand the technical solutions of the embodiments of the present invention, and are not intended to be the only limitation on the embodiments of the present invention.

[0056] Secondly, the present invention provides an automobile comprising a connection structure between the side assembly and the panoramic sunroof as described in any of the first aspects above.
