Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a skylight glass connection structure and a vehicle. Background Art

[0002] The panoramic skylight is a large glass roof or skylight located on the roof of the car, usually covering most of the area between the front and rear seats, as well as part of the roof area. It replaces the traditional roof of the car to break the size and field of view of the traditional car skylight, and increase the comfort and driving experience of passengers. Since the skylight glass is a structure connected to the car body, in order to prevent the panoramic skylight glass from falling off under negative pressure conditions in the car when driving at high speed, most of the connection strength between the skylight glass and the car body is strengthened, that is, by injection molding or bonding hard nut connectors to lock the connection with the car body sheet metal through bolt standard parts. After the above structure is coated and solidified with the car body glass glue, the skylight glass and the car body will be in a hard connection state. When the vehicle is driven for a long time on bad mountain roads or extreme road conditions, the deformation of the car body frame will form a multi-directional repeated force and be transmitted to the skylight glass through the locking point; when the stress state reaches the stress limit of the glass itself or the repeated endurance fatigue limit, the skylight glass will break and fall, which will pose a risk to the personal safety of passengers.

[0003] Therefore, how to improve the safety of using panoramic skylight glass is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0004] The utility model proposes a skylight glass connection structure and a vehicle to improve the use safety of the panoramic skylight glass.

[0016] Optionally, in the above-mentioned skylight glass connection structure, the gap between the limiting section and the tongue piece is 3mm-5mm.

[0017] Optionally, in the above-mentioned skylight glass connection structure, a positioning pin is fixedly provided on the skylight glass, and a positioning hole is correspondingly provided on the top wall surface, and the positioning pin is inserted into the positioning hole to align the connection end and the connection hole.

[0018] Optionally, in the above-mentioned skylight glass connection structure, the connecting end is adhesive and is bonded and fixed to the first end of the connecting bolt, the limiting section is a nut cap, and the second end of the connecting bolt is provided with anti-loosening glue and is threadedly connected to the nut cap.

[0019] Optionally, in the above-mentioned skylight glass connection structure, the connection hole is circular and is opened in the central area of ​​the tongue piece.

[0020] In a second aspect, the utility model provides a vehicle, wherein a skylight glass is arranged on the top of the vehicle body, and the vehicle body and the skylight glass are assembled and connected by the skylight glass connection structure provided by any one of the above embodiments.

[0030] The panoramic skylight is of great significance in enhancing the luxury feel of the vehicle and satisfying the passengers' comfort and driving experience. However, due to the assembly connection between the skylight glass and the car body, designers have strengthened the connection strength of the connection structure in order to maintain the stable connection of the skylight glass. However, the rigidly locked skylight glass and car body sheet metal will cause the deformation of the car body frame to form a multi-directional repeated force on roads with poor road conditions, and transmit it to the skylight glass through the locking point, causing the skylight glass to break or fall.

[0031] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0032] See also Figure 1 , Figure 2 and Figure 3 The skylight glass connection structure provided in the embodiment of the utility model is used to connect the skylight glass 40 and the body sheet metal 50. Specifically, the skylight glass connection structure mainly includes a connection end 10, a tongue 20 and a connection bolt 30. Among them, the connection end 10 is fixedly arranged on the skylight glass 40 to serve as the connection basis of the skylight glass 40. It should be noted here that the connection end 10 is an extension structure of the skylight glass 40. In order to maintain the structural strength of the skylight glass 40, the skylight glass 40 is usually a complete structure and the open hole structure is avoided as much as possible. Therefore, the connection end 10 can have a good connection effect with the skylight glass 40 through pre-embedded injection molding, glass glue bonding, etc., so as to connect the skylight glass 40 and maintain the integrity of the skylight glass 40.

[0033] The tongue piece 20 is a flexible structure extending from the body sheet metal 50. It is a protruding structure based on the top wall surface 510 of the body sheet metal 50 and protruding in a direction perpendicular to the top wall surface 510. At the same time, only a single side of the tongue piece 20 is fixed to the top wall surface 510, so that while the body sheet metal 50 maintains a stable structure, the tongue piece 20 has the function of elastically floating in a direction perpendicular to the top wall surface 510. At the same time, a connecting hole 210 is opened on the tongue piece 20 to cooperate with the connecting end 10, and a connecting bolt 30 is passed through to realize the connection between the skylight glass 40 and the body sheet metal 50. It should be noted that the protruding extension of the tongue 20 is arranged to realize its elastic floating function and to provide a certain flexible connection effect. Therefore, the tongue 20 can protrude vertically upward or vertically downward in a direction perpendicular to the top wall surface 510. In some embodiments of the present invention, in order to facilitate the assembly of the connecting bolt 30, the tongue 20 protrudes vertically downward in a direction perpendicular to the top wall surface 510, that is, it protrudes in the insertion direction of the connecting bolt 30 to improve the convenience of the connection operation.

[0034] See also Figure 5 and Figure 6 , and the connecting bolt 30 used to connect the skylight glass 40 and the body sheet metal 50 passes through the connecting hole 210 through its first end and is fixedly connected to the connecting end 10. It should be noted that the area where the connecting bolt 30 passes through the connecting hole 210 is gap-matched with the connecting hole 210, so that the tongue 20 still has elastic action after the connecting bolt 30 passes through. At the same time, the connecting bolt 30 also includes a limiting section 310 with an outer diameter greater than the outer diameter of the connecting hole 210, that is, a structure that extends and protrudes toward the periphery based on the outer wall of the connecting bolt 30, the limiting section 310 is spaced apart from the tongue 20, and the limiting section 310 and the connecting end 10 are respectively located on both sides of the tongue 20 in a direction perpendicular to the top wall surface 510. It should be noted that the spacing between the limit section 310 and the tongue piece 20 can provide a jumping space for the tongue piece 20 to achieve a flexible connection, thereby reducing the risk of stress concentration at the connection structure; the limit section 310 and the connecting end 10 are respectively located on both sides of the tongue piece 20, so that the connecting bolt 30 can lock the tongue piece 20 and the connecting end 10; at the same time, when there is a risk of failure of the glass glue of the skylight glass 40, the skylight glass 40 separated from the vehicle body sheet metal 50 can still lock the two sides of the tongue piece 20 at the connecting end 10 and the limit section 310, thereby limiting the skylight glass 40 and avoiding the risk of the skylight glass 40 jumping and falling off.

[0035] The skylight glass connection structure provided in the embodiment of the utility model is weakened from the reverse direction of strengthening the locking structure in order to improve the safety of the skylight glass 40. Specifically, the skylight glass connection structure includes a connection end 10, a tongue piece 20 and a connection bolt 30, wherein the connection end 10 and the skylight glass 40 are fixedly connected as an integrated structure by glass glue bonding, pre-embedded injection molding, etc., so as to serve as a fixed structure of the skylight glass 40 and maintain the integrity of the skylight glass 40; the tongue piece 20 is a sheet metal piece extending from the top wall surface 510 of the body sheet metal 50 and is fixed to the top wall surface 510 only by a single side edge to have an elastic effect. On this basis, the connection bolt 30 passes through the connection hole 210 on the tongue piece 20 and is locked and connected to the connection end 10, and is limitedly matched with the tongue piece 20 through the limiting section 310. In the above structure, the tongue 20 itself has the ability to elastically deform in a direction perpendicular to the top wall surface 510. There is a gap between the upper limit section 310 of the connecting bolt 30 and the tongue 20. Therefore, the integrated structure connecting the skylight glass 40 and the tongue 20 has a floating ability, and can reduce the risk of stress concentration through elastic action when the body deformation transmits stress, thereby reducing the risk of breakage or falling of the skylight glass 40. At the same time, the structure of the connecting bolt 30 and the skylight glass 40 has an elastic range compared to the spring sheet, that is, the distance between the tongue 20 and the limit section 310, which can also maintain the floating ability when the tongue 20 elastically fails and reduce the risk of stress concentration, thereby improving the safety of the skylight glass 40 during driving.

[0036] Further, in some embodiments of the present invention, see Figure 2 The connecting end 10 on the skylight glass 40 is a rubber-encapsulated nut 110 and is pre-embedded in the glue injection area of ​​the skylight glass 40, so as to form a stable integrated structure with the skylight glass 40 after the glass glue is applied on the skylight glass 40. Correspondingly, the outer periphery of the first end of the connecting bolt 30 is provided with anti-loosening glue and is thread-locked with the rubber-encapsulated nut 110. It should be noted that the limiting section 310 and the connecting bolt 30 in the above structure are an integrated structure, so when assembling, it is only necessary to align the connecting bolt 30 from the inside of the body sheet metal 50 and tighten it to complete the assembly, which is simple to operate, and the threaded matching structure is easy to disassemble and assemble, and the operation is simple.

[0037] On the basis of the above embodiment, the tongue piece 20 is preferably arranged at the same interval as the rubber-coated nut 110, so that there is a gap on both sides of the tongue piece 20 facing the rubber-coated nut 110 and the limiting section 310, and while meeting the connection requirements, the elastic deformation space of the tongue piece 20 is increased, and a larger deformation margin is provided for the skylight glass 40. On this basis, the spacing between the tongue piece 20 and the rubber-coated nut 110 is 3mm-5mm to meet the deformation requirements and avoid affecting the connection strength due to excessive spacing.

[0038] At the same time, in order to ensure the connection effect between the connecting bolt 30 and the rubber-coated nut 110, it is necessary to select a connecting bolt 30 and a rubber-coated nut 110 of sufficient length to ensure that the connecting bolt 30 and the rubber-coated nut 110 are locked by at least five threads, combined with the anti-loosening glue set on the outer wall of the connecting bolt 30 to improve the stability of the connection.

[0039] Considering that the structure of the tongue piece 20 is based on the extended structure of the body sheet metal 50, there is a delayed movement effect between the tongue piece 20 and the main structure of the body sheet metal 50, so there is also a risk of stress concentration at the connection position between the tongue piece 20 and the body sheet metal 50. Based on this, in some embodiments of the utility model, the connection area between the tongue piece 20 and the top wall surface 510 is set as a rounded structure to reduce the risk of stress concentration, and in order to balance the connection strength, the radius of the rounded structure of the connection area between the tongue piece 20 and the top wall surface 510 is preferably 3mm-5mm. At the same time, the protrusion height of the tongue piece 20 compared to the top wall surface 510 is 3mm-5mm. On the one hand, the protrusion height of 3mm-5mm can meet the elastic deformation requirements of the tongue piece 20 and maintain the connection strength. On the other hand, the protrusion height of the tongue piece 20 is close to the radius of its rounded result, which can make the tongue piece 20 tilted at nearly 45 degrees compared to the bending structure of the top wall surface 510 when the top wall surface 510 remains horizontal, so that the longitudinal elastic deformation effect and the lateral connection strength requirements can be more balanced.

[0040] In order to further optimize the use safety of the skylight glass connection structure, in some embodiments of the present utility model, the connection bolt 30 is centrally arranged in the connection hole 210 to improve the locking effect of the connection bolt 30, so that the force applied to the connection bolt 30 can be evenly transmitted around the tongue 20. At the same time, the connection bolt 30 and the connection hole 210 are in a clearance fit state, that is, the clearance between the connection hole 210 and the connection bolt 30 in one direction is not less than 2.5 mm. It should be noted that the one-way clearance here specifically refers to the clearance between the outer wall of the connection bolt 30 and the inner wall of the connection hole 210 along any radius extending from the central axis of the connection bolt 30. Here, setting the connection bolt 30 and the connection hole 210 as clearance fit can provide the deformation ability relative to the tongue 20 for the integrated structure of the connection bolt 30 and the skylight glass 40 on the basis of meeting the connection strength. Based on the elastic deformation effect of the above-mentioned embodiment, the skylight glass connection structure provided by the embodiment of the utility model has a multi-stage floating connection structure, and has sufficient flexible connection effect to improve the use safety of the skylight glass 40.

[0041] On this basis, the outer diameter of the limiting section 310 on the connecting bolt 30 is 4mm-6mm larger than the outer diameter of the connecting hole 210, that is, there is an interference amount of 2mm-3mm on one side in the direction perpendicular to the top wall surface 510, so as to effectively limit the tongue piece 20. After the glass glue on the skylight glass 40 fails, the limiting section 310 can prevent the integrated structure of the connecting bolt 30 and the skylight glass 40 from falling off from the tongue piece 20 through the limiting effect of interference fit, so that the skylight glass 40 can maintain a stable connection with the body sheet metal 50.

[0042] Furthermore, in some embodiments of the present invention, the gap between the limiting section 310 and the tongue piece 20 is 3 mm-5 mm to provide sufficient floating amount for the skylight glass 40 .

[0043] To improve assembly accuracy, see Figure 2 and Figure 3 , a positioning pin 410 is fixedly provided on the skylight glass 40, and a positioning hole 520 is correspondingly provided on the top wall surface 510 of the body sheet metal 50. The skylight glass 40 is pre-positioned by the plug-in cooperation of the positioning pin 410 and the positioning hole 520, so that the positioning pin 410 is inserted into the positioning hole 520 to align the connection end 10 and the connection hole 210, so that the assembler can lock the connection. It should be noted that in order to enable the positioning pin 410 to achieve effective positioning, it is preferred that the positioning pin 410 is arranged close to the connection end 10, that is, the positioning hole 520 is arranged in the peripheral area of ​​the tongue piece 20, so as to effectively position the connection position of the skylight glass 40 and the body sheet metal 50 with a larger size.

[0044] It should be further explained that, in some embodiments of the utility model, the positioning hole 520 is set to be an oblong hole structure. For the larger-sized skylight glass 40 and the body sheet metal 50, after the cylindrical positioning pin 410 is plugged into the positioning hole 520, the position can also be adjusted within the range of the oblong hole to meet the alignment effect of the connecting end 10 and the connecting hole 210.

[0045] The above embodiment is described with the structure that the connecting end 10 is a rubber-encapsulated nut 110 and is pre-embedded in the glue injection area of ​​the skylight glass 40, see Figure 4In other embodiments of the present invention, the connecting end 10 is a structure formed by adhesive 120 and is bonded and fixed to the first end of the connecting bolt 30. It should be noted that the connecting bolt 30 needs to be pre-buried to be integrally formed with the adhesive 120 to achieve effective fixed connection between the connecting bolt 30 and the connecting end 10, and then pass through the tongue piece 20 to achieve locking. The connecting bolt 30 passes through the connecting hole 210 on the tongue piece 20, and the outer wall of the structure needs to be smaller than the inner diameter of the connecting hole 210. Therefore, in this embodiment, the limiting section 310 on the connecting bolt 30 is a limiting structure installed after the connecting bolt 30 passes through the tongue piece 20. In a preferred embodiment of the present invention, the limiting section 310 is a nut cap 320, and the second end of the connecting bolt 30 is provided with anti-loosening glue and is threadedly connected to the nut cap 320 to achieve locking.

[0046] Furthermore, in some embodiments of the present invention, the connecting hole 210 is circular and is opened in the central area of ​​the tongue 20 to improve the uniformity of force on the tongue 20. When subjected to force, the connecting hole 210 can evenly transfer force to other areas of the tongue 20, thereby improving the service life of the tongue 20.

[0047] Furthermore, some embodiments of the utility model also disclose a vehicle, which is provided with a skylight glass 40 on the top of the vehicle body, and the sheet metal structure of the vehicle body and the skylight glass 40 are assembled and connected by the skylight glass connecting structure provided by any of the above embodiments. Since the above-mentioned skylight glass connecting structure has the above effects, the above-mentioned vehicle also has the corresponding effects, which will not be repeated here. It should be noted that the above-mentioned vehicle can be a pure electric drive vehicle, a hybrid vehicle or a fuel vehicle, etc.

[0048] It should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the utility model can be combined with each other.
