[0039] Embodiment 1

[0040] like Figure 1 As shown, the first aspect of the present application provides a roof trim and body sheet metal connection structure, which includes a support portion 1, a connection portion 2 and a fastening portion 3; a first side 11 of the support portion 1 is at least partially capable of connecting to a roof trim 4, a second side 12 of the support portion 1 away from the first side 11 has an opening 14 and a snap-in space 15 in the opening 14; a first end of the connection portion 2 is snapped into the snap-in space 15, a second end of the connection portion 2 protrudes and extends away from the support portion 1, a waterproof seal 21 is sleeved on the position of the connection portion 2 protruding from the support portion 1, and the waterproof seal 21 is used to embed the body sheet metal 5; the fastening portion 3 is sleeved on the connection portion 2 and is located along the side of the waterproof seal 21 away from the support portion 1, and the fastening portion 3 is used to fasten the body sheet metal 5 and the waterproof seal 21.

[0041] Specifically, the present application forms a connection and fixation between the body sheet metal 5 and the roof trim 4 through the support part 1, the connection part 2 and the fastening part 3. The support part 1 serves as a structural frame for the clamping connection part 2. Its material can be metal or plastic, or elastic materials such as rubber, polyurethane, or a partially elastic structure. There is no specific limitation as long as it can play a supporting and connecting role. The first side 11 of the support part 1 can at least partially connect to the roof trim 4. The connection method can be welding, screw connection, or the roof trim 4 has a preset clamping groove to clamp the support part 1. There is no specific limitation as long as the connection between the support part 1 and the roof trim 4 can be achieved. The second side 12 of the support part 1 facing away from the first side 11 has an opening 14, and the opening 14 has a clamping space 15. The clamping space 15 can clamp the first end of the connection part 2 to achieve the support and fixation of the connection part 2 by the support part 1.

[0042] The connection part 2 can be a bolt or a non-standard connection structure. In some embodiments, when the connection part 2 is a bolt, the first end of the connection part 2 is a bolt head, which has various forms such as a hexagonal head, a square head, a round head, a countersunk head, etc. The second end of the connection part 2 protrudes and extends away from the support part 1 is a screw rod, which is provided with threads. The outer edge size of the bolt head is larger than the screw rod, so that the bolt head as the first end of the connection part 2 can be clamped in the clamping space 15, and the waterproof seal 21 and the fastening part 3 are connected to the screw rod. In other embodiments, the connection part 2 can be a non-standard connection structure. In order to meet its clamping and assembly requirements, it is necessary to ensure that the first end of the connection part 2 can be clamped in the clamping space 15, and the position of the connection part 2 protruding from the support part 1 can be sleeved with a seal and assembled with the fastening part 3.

[0043] In order to provide good waterproof sealing performance during the connection process between the body sheet metal 5 and the roof trim 4, the present application sets a waterproof seal 21 at the position where the connecting part 2 protrudes from the supporting part 1. The setting of the waterproof seal 21 makes up for the installation gap between the body sheet metal 5 and the connecting part 2 and seals and waterproofs to prevent the body structure and circuit system from being corroded and damaged. The waterproof seal 21 can be in various forms such as rubber seals, plastic seals, metal seals, sponge seals, and sealing water-stopping strips, and the specific form is not limited, as long as it can achieve a good waterproof sealing effect.

[0044] When the first end of the connecting part 2 is clamped into the clamping space 15, in order to fix the waterproof seal 21, the present application is provided with a fastening part 3. When the connecting part 2 is a bolt, the fastening part 3 can select a nut 31 that can be threadedly connected to the screw rod of the bolt, and be configured with gaskets, washers and other fastening elements. When the connecting part 2 is a non-standard connecting structure, the fastening part 3 is adaptively arranged to be sleeved on the connecting part 2 to fasten the body sheet metal 5 and the waterproof seal 21. The connection between the fastening part 3 and the connecting part 2 can be achieved by welding, riveting, pin fixing and the like, without limitation, as long as a tight connection between the fastening part 3 and the connecting part 2 can be achieved. The function of the fastening part 3 is to fasten and fix the waterproof seal 21 sleeved on the connecting part 2, and since the waterproof seal 21 is embedded with the body sheet metal 5, the body sheet metal 5 and the waterproof seal 21 are fastened and fixed.

[0045] A first aspect of the present application provides a roof trim and body sheet metal connection structure and a new energy vehicle, the roof trim and body sheet metal connection structure comprising a support portion 1, a connection portion 2 and a fastening portion 3; a first side 11 of the support portion 1 is at least partially connectable to a roof trim 4, a second side 12 of the support portion 1 facing away from the first side 11 has an opening 14 and a snap-in space 15 in the opening 14; a first end of the connection portion 2 is snapped into the snap-in space 15, a second end of the connection portion 2 protrudes and extends away from the support portion 1, a waterproof seal 21 is sleeved on the position of the connection portion 2 protruding from the support portion 1, and the waterproof seal 21 is used to embed the body sheet metal 5; the fastening portion 3 is sleeved on the connection portion 2 and is located along the side of the waterproof seal 21 facing away from the support portion 1, and the fastening portion 3 is used to fasten the body sheet metal 5 and the waterproof seal 21. The present application sets a support part 1 to connect the roof trim 4 and clamp the connection part 2, sets a waterproof seal 21 on the connection part 2, embeds the body sheet metal 5 in the waterproof seal 21, and sets a fastening part 3 to fasten the body sheet metal 5 and the waterproof seal 21, thereby realizing the connection between the roof trim 4 and the body sheet metal 5. At the same time, the setting of the waterproof seal 21 fills the installation gap between the body sheet metal 5 and the connection part 2 and provides good waterproof sealing performance. Through the application of the present application, the roof trim 4 and the body sheet metal 5 are stably matched and connected, and have good waterproof sealing performance, protecting the body structure and circuit system from corrosion and damage, and ensuring the safety performance of the car.

[0046] In some embodiments, the waterproof seal 21 is elastic.

[0047] Specifically, in order to further improve the waterproof performance and sealing performance provided by the waterproof seal 21 during the connection between the roof trim 4 and the body sheet metal 5, the present application sets an elastic waterproof seal 21, so that the waterproof seal 21 can cope with the driving scenes such as vibration and shaking of the vehicle body during use. Due to its high elasticity and ductility, it can maintain a certain recovery ability after deformation and ensure the stability of the seal. At the same time, the body sheet metal 5 is embedded in the elastic waterproof seal 21, which fits more tightly to prevent moisture and corrosive media from penetrating. In addition, the elastic waterproof seal 21 facilitates the installation operation of workers and reduces labor intensity. The elastic waterproof seal 21 of the present application can be selected from a variety of rubber sealing rings, silicone or silicone grease sealing rings, sponge sealing rings, polyurethane sealing rings, etc., without limitation, as long as it can provide good waterproof sealing performance on the basis of elasticity.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the position where the connecting portion 2 protrudes from the supporting portion 1 is also connected to a limiting member 22 , and the limiting member 22 is disposed on a side of the waterproof sealing member 21 away from the fastening portion 3 .

[0049] Specifically, in order to provide support for the waterproof seal 21 and ensure its waterproof sealing performance, the present application sets a limiter 22 on the connection part 2. The limiter 22 is set on the side of the waterproof seal 21 away from the fastening part 3 to provide support for the waterproof seal 21, and at the same time make up for the gap that may exist between the second side 12 of the support part 1 and the waterproof seal 21, avoiding the hidden danger of water leakage. The limiter 22 can be a gasket, a washer, or a boss integrally formed with the connection part 2, and there is no specific limitation. The outer edge size of the limiter 22 can be set to be consistent with the outer edge size of the waterproof seal 21 to ensure that the waterproof seal 21 is fully supported and the stability of the support between the structures is improved.

[0050] like Figure 1 As shown, in some embodiments, a preset gap 16 is provided between the second side 12 of the support portion 1 and a surface of the limiting member 22 facing away from the waterproof sealing member 21 .

[0051] Specifically, in some embodiments, when a worker inserts the connection part 2 through the opening 14 of the second side 12 of the support part 1 to snap the first end of the connection part 2 into the snap-in space 15 in the opening 14, in order to facilitate installation, the present application sets a preset gap 16 between the second side 12 of the support part 1 and the surface of the side of the stopper 22 away from the waterproof seal 21. The size of the preset gap 16 should not be too small or too large, and is set at about 1 mm to avoid that when the preset gap 16 is too small, the second side 12 of the support part 1 forms abutment against the stopper 22 when the connection part 2 is installed, or the gap between the two is too small to cause friction, and the installation of the preset position can only be achieved by means such as knocking with tools, thereby increasing the difficulty of installation and unnecessary labor costs. When the gap is too large, the stability of the connection of the connection part 2 is affected, so the present application sets a preset gap 16, and it should be noted that the preset gap 16 is about 1 mm, so as to provide a suitable operating space for the installation of the connection part 2, facilitate installation, and improve the stability of the connection.

[0052] like Figure 2 As shown, in some embodiments, the opening 14 extends to the third side 13 where the support portion 1 is connected to the second side 12 , and the first end of the connecting portion 2 can enter the snap-in space 15 along the third side 13 for snap-in.

[0053] Specifically, in order to facilitate installation, the opening 14 of the support part 1 of the present application extends to the third side 13 where the support part 1 is connected to the second side 12. Taking into account the structure of the connecting part 2 itself and the waterproof seal 21 thereon occupying a certain volume space, the present application enables the first end of the connecting part 2 to enter the snap-in space 15 along the third side 13 for snap-in. That is, when the roof trim 4 is placed horizontally and the connecting part 2 is installed, it is only necessary to extend the connecting part 2 along the third side 13 of the support part 1 in a horizontal direction to achieve the snap-in of the first end of the connecting part 2 into the snap-in space 15, which is convenient for installation.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments, the connecting part 2 includes a clamping joint 23 and a connecting rod 24, the clamping joint 23 is connected to the connecting rod 24 and is located at the first end of the connecting part 2, and the outer edge size of the clamping joint 23 is larger than the connecting rod 24; the clamping space 15 includes a first space 151 and a second space 152 that are connected, the outer edge size of the first space 151 is larger than the second space 152, the clamping joint 23 can be clamped in the first space 151, and the connecting rod 24 can be passed through the second space 152.

[0055] Specifically, in order to realize the clamping of the connection part 2 in the clamping space 15, the present application sets the connection part 2 to include a clamping joint 23 and a connecting rod 24. The connection part 2 can be a bolt or a non-standard connection structure. In some embodiments, when the connection part 2 is a bolt, the clamping joint 23 is a bolt head, which has a variety of forms such as a hexagonal head, a square head, a round head, a countersunk head, etc. The connecting rod 24 is a screw rod, which is provided with threads, and the outer edge size of the bolt head is larger than the screw rod, so that the bolt head as the first end of the connection part 2 can be clamped in the first space 151 with a larger size, and the screw rod can pass through the second space 152, and the waterproof seal 21 and the fastening part 3 are connected to the screw rod. In other embodiments, the connection part 2 can be a non-standard connection structure. In order to meet its clamping and assembly requirements, it is necessary to ensure that the outer edge size of the clamping joint 23 is larger than the connecting rod 24, and the waterproof seal 21 and the fastening part 3 can be assembled on the connecting rod 24.

[0056] like Figure 2 and Figure 3 As shown, in some embodiments, an elastic member 153 is provided on the side wall of the snap-in space 15 away from the second side 12 of the support portion 1, and the elastic member 153 is provided on the path of the snap-in joint 23 entering the snap-in space 15 along the opening 14; wherein, the snap-in joint 23 enters the snap-in space 15 along the opening 14, the elastic member 153 is compressed, the snap-in joint 23 is snap-into the first space 151, and the elastic member 153 recovers and presses against a side surface of the snap-in joint 23 facing the third side 13.

[0057] Specifically, when the roof trim 4 is placed horizontally, when the connection part 2 is installed, it is only necessary to extend the connection part 2 along the third side 13 of the support part 1 in the horizontal direction. In order to provide abutment support to the side of the clamping joint 23 after the clamping joint 23 is clamped in the first space 151 without interfering with the extending action of the connection part 2, the present application provides an elastic member 153 on the path of the clamping joint 23 entering the clamping space 15 along the opening 14. When the clamping joint 23 enters the clamping space 15 along the opening 14, the elastic member 153 is compressed, the clamping joint 23 is clamped in the first space 151, and the elastic member 153 recovers and abuts against the side surface of the clamping joint 23 facing the third side 13. The elastic member 153 can be integrally formed with the support part 1, or can be connected to the side wall of the clamping space 15 away from the second side 12 of the support part 1 by screws, pins, rivets, etc., without specific limitation. The elastic member 153 may be made of materials such as rubber, silicone, and polyurethane, and in order to facilitate the horizontal extension of the connecting portion 2 from the third side 13 of the supporting portion 1, the elastic member 153 may be provided with an inclined slope, the slope facing away from the card-joining space 15, so that when the card joint 23 enters the card-joining space 15 along the opening 14, it has a deformation tendency in the same direction, and after the card joint 23 is card-joined in the first space 151, it can be restored and pressed against the side surface of the card joint 23 facing the third side 13 under the action of elastic force, thereby realizing the pressing support for the side of the card joint 23, and ensuring the stability of the connection structure between the roof trim and the body sheet metal.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the fastening portion 3 includes a nut 31 , which is threadedly connected to the connecting portion 2 and has one side abutting against a side of the waterproof sealing member 21 facing away from the supporting portion 1 .

[0059] Specifically, when the first end of the connecting part 2 is snapped into the snap-in space 15, in order to fix the waterproof seal 21, the fastening part 3 of the present application includes a nut 31, and the corresponding connecting part 2 is provided with a thread. The nut 31 is threadedly connected to the connecting part 2 to achieve the adjustment of the position of the nut 31, and the waterproof seal 21 is fixed to a preset position on the connecting part 2, while ensuring that the waterproof seal 21 exerts a stable waterproof sealing performance.

[0060] like Figure 1 and Figure 2 As shown, in some embodiments, the fastening portion 3 also includes a conical elastic washer 32; the conical elastic washer 32 is arranged between the nut 31 and the waterproof seal 21, and the side surface of the conical elastic washer 32 facing away from the nut 31 at least partially abuts against the waterproof seal 21, and can at least partially abut against the body sheet metal 5.

[0061] Specifically, the fastening part 3 of the present application also includes a conical elastic washer 32, which is arranged between the nut 31 and the waterproof seal 21. The conical elastic washer 32 can effectively absorb and disperse the load through its elastic deformation when subjected to force, compensate for the looseness between the body sheet metal 5 and the waterproof seal 21 caused by body vibration, thermal expansion, etc., ensure the stability and reliability of the connection, and improve the waterproof sealing performance of the connection structure between the roof trim panel and the body sheet metal of the present application.

[0062] The surface of the conical elastic washer 32 on one side facing away from the nut 31 at least partially abuts against the waterproof seal 21, and can at least partially abut against the body sheet metal 5, so that the conical elastic washer 32 can simultaneously provide fastening support for the waterproof seal 21 and the body sheet metal 5, and improve the connection stability when the body sheet metal 5 is embedded in the waterproof seal 21. In some embodiments, the outer edge size of the conical elastic washer 32 is larger than the nut 31, and also larger than the outer edge size of the waterproof seal 21, and the surface of the conical elastic washer 32 on one side facing away from the nut 31 is a slope with a certain angle, and the slope abuts against the body sheet metal 5 and the waterproof seal 21 at the same time.
