Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a bracket assembly for a car tailgate strut, a tailgate assembly, and a vehicle. Background Technology

[0002] In the existing technology, most vehicles with hatchback doors open and close the hatch by hinges connecting the hatch and the vehicle body. At the same time, the support force of electric or pneumatic hatchback rods balances the weight of the hatch, making it easier to open and close. The hatchback rods are mostly arranged in the drainage channels on both sides of the rear of the vehicle body. The brackets that fix the hatchback rods are particularly important. The hatchback rod is connected at one end to the support rod bracket with a ball head on the side of the vehicle body through a ball socket, and at the other end to the support bracket with a ball head on the side of the hatchback door. Because the side strut bracket is connected to the vehicle body and located inside the drainage channel, it is crucial to ensure not only reliable and secure installation but also excellent waterproof sealing. Currently, most vehicle models on the market use waterproof gaskets glued between the bracket and the vehicle body. While these gaskets provide a seal, once the strut bracket is bolted to the vehicle body, the gaskets experience some creep under pressure. This results in a less than perfect rigid connection between the strut bracket and the vehicle body. Over time, the torque of the bolts securing the strut bracket decreases significantly, reducing the clamping force between the strut bracket and the vehicle body, further affecting the bracket's sealing and stability. Utility Model Content

[0003] In view of this, the present invention provides a bracket assembly for a car tailgate strut, which can effectively prevent rainwater, car wash water, etc. from entering the car or causing corrosion of the sheet metal.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] In a first aspect, this utility model provides a bracket assembly for a car rear door strut, comprising: a bracket body and a ball joint pin, the ball joint pin being connected to the bracket body, the bracket body having a mounting hole, the mounting hole having a sealing portion formed circumferentially, and the sealing portion having a sealing element to seal the bracket body and the rear sheet metal of the vehicle body.

[0006] According to the present invention, the bracket assembly of the car rear door support rod has a sealing element set in the circumferential direction of the mounting hole. The sealing element forms an effective waterproof layer under the tightening of the bolt, preventing rainwater, car wash water, etc. from entering the car or causing sheet metal corrosion. This improves the sealing effect and connection stability between the bracket assembly and the rear sheet metal of the car body, and enhances the durability and comfort of the vehicle.

[0007] In one possible implementation of this utility model, the sealing part is formed as a sealing groove that extends circumferentially around the mounting hole, and at least a portion of the sealing element is located within the sealing groove.

[0008] Thus, by forming a sealing groove to accommodate and restrict the seal, the seal is prevented from shifting or being squeezed and deformed unevenly during assembly. This helps to maintain the stability of the seal position and avoids uneven distribution of clamping force due to the cheapness of the seal, thereby improving the connection and sealing performance between the bracket assembly and the rear sheet metal of the vehicle body.

[0009] In one possible implementation of this utility model, the sealing element is switchable between a first state and a second state. When the sealing element is in the first state, a portion of the sealing element is located outside the sealing groove. When the sealing element is in the second state, the sealing element is completely located inside the sealing groove.

[0010] Thus, by deformably setting the seal in the sealing groove, when the seal is in the first state, part of the seal is located outside the sealing groove, that is, the seal is not compressed and deformed. When the seal is in the second state, the seal is compressed and deformed, and the seal fills the gap between the bracket body and the rear sheet metal of the vehicle body, thus forming an effective seal.

[0011] In one possible implementation of this utility model, the axial dimension of the seal is not less than the depth of the sealing groove.

[0012] Thus, in the first state, part or all of the seal is above the surface of the sealing groove, thereby having a certain amount of pre-pressure during assembly. In this way, the seal stably fits the surface of the rear sheet metal of the vehicle body after being compressed, improving the sealing consistency.

[0013] In one possible implementation of this utility model, the mounting hole includes a first hole and a second hole, the first hole and the second hole are respectively located on the radial sides of the ball head pin, and a sealing groove is formed in the circumferential direction of both the first hole and the second hole.

[0014] In this way, by setting two mounting holes (i.e., the first hole and the second hole) to firmly fix the bracket assembly to the vehicle body, the overall structural rigidity is enhanced. The first hole and the second hole are respectively set on the radial sides of the ball head pin, which can prevent the bracket assembly from deflecting or loosening due to unilateral force, thus ensuring the connection stability and reliability of the bracket assembly.

[0015] In one possible implementation of this utility model, at least one of the first hole and the second hole is formed as an oblong hole.

[0016] Thus, in the actual manufacturing and assembly process, there may be processing errors, assembly deviations or differences in thermal expansion between the body sheet metal, the bracket body, and the bolt installation position. The waist-shaped hole is a non-circular through hole with semi-circular ends, a rectangular middle, and an overall "waist" or "racetrack" shape. It can be used to adjust the relative installation position between the bracket body and the rear body sheet metal. Even if there are tolerances, the bracket body and the rear body sheet metal can still be installed smoothly.

[0017] In one possible implementation of this utility model, the bracket body has a first plate and a second plate connected to both sides of the first plate. The first plate is disposed away from the rear sheet metal of the vehicle body. The ball pin is disposed on the first plate, and the mounting hole and the sealing part are both located on the second plate.

[0018] Thus, by setting up a first plate and a second plate that are not on the same plane, when the ball head pin is under force, the ball head pin will transfer the force to the first plate. The first plate is arranged separately from the rear sheet metal of the vehicle body, which plays the role of suction and buffer. The second plate is rigidly connected to the rear sheet metal of the vehicle body through fasteners, which avoids the loss of clamping force between the bracket body and the rear sheet metal of the vehicle body, and ensures the connection stability between the bracket body and the rear sheet metal of the vehicle body.

[0019] In one possible implementation of this utility model, the sealing portion is formed on the side of the bracket body facing the rear sheet metal of the vehicle body.

[0020] Secondly, this utility model provides a tailgate assembly, including: a tailgate support rod, a rear body sheet metal, and a bracket assembly for the tailgate support rod provided in any of the first embodiments above. The tailgate support rod is connected to the bracket assembly by a ball joint pin, and the bracket assembly is connected to the rear body sheet metal through mounting holes.

[0021] The rear tailgate assembly provided in this embodiment of the utility model, since it includes the bracket assembly of the car rear tailgate strut provided in any of the embodiments of the first aspect above, has the same technical effect, that is, by setting a sealing element in the circumferential direction of the mounting hole, the sealing element forms an effective waterproof layer under the tightening of the bolt, preventing rainwater, car wash water, etc. from entering the car or causing sheet metal corrosion, improving the sealing effect and connection stability between the bracket assembly and the rear sheet metal of the car body, and improving the durability and comfort of the vehicle.

[0022] Thirdly, this utility model provides a vehicle that includes the tailgate assembly provided in any of the embodiments of the second aspect above.

[0023] The vehicle provided in this embodiment of the utility model, by including the tailgate assembly provided in the second aspect above, can effectively prevent rainwater, car wash water, impurities, dust, etc. from entering the vehicle body, avoid corrosion of sheet metal, improve the production quality and durability of the vehicle, and extend the service life of the vehicle.

[0044] Most vehicles with hatchback doors open and close via hinges connecting the hatchback to the vehicle body. The hatchback's weight is balanced by the support force of electric or pneumatic struts, making it easy to open and close. The struts are mostly located in the drainage channels on both sides of the rear of the vehicle. The brackets that fix the struts are particularly important. One end of the hatchback strut is connected to the strut bracket with a ball joint on the side of the vehicle body via a ball joint, and the other end is connected to the bracket with a ball joint on the side of the hatchback. Because the side strut bracket is connected to the vehicle body and located inside the drainage channel, it is crucial to ensure not only reliable and secure installation but also excellent waterproof sealing. Currently, most vehicle models on the market use waterproof gaskets glued between the bracket and the vehicle body. While these gaskets provide a seal, once the strut bracket is bolted to the vehicle body, the gaskets experience some creep under pressure. This results in a less than perfect rigid connection between the strut bracket and the vehicle body. Over time, the torque of the bolts securing the strut bracket decreases significantly, reducing the clamping force between the strut bracket and the vehicle body, further affecting the bracket's sealing and stability.

[0045] In view of this, the present invention provides a bracket assembly for a car rear door strut, which improves the sealing and robustness of the bracket assembly after assembly.

[0046] It should be noted that the vehicles or automobiles mentioned in this utility model can refer to large automobiles, small automobiles, special-purpose vehicles, etc. For example, according to the vehicle type, the vehicles or automobiles in this utility model can be sedans, off-road vehicles, multi-purpose vehicles (MPVs), or other types of vehicles.

[0047] The following is for reference. Figures 1-8 This invention describes a bracket assembly 100 for a car tailgate support rod 300 according to an embodiment of the present invention.

[0048] Specifically, the bracket assembly 100 of the car tailgate strut 300 includes: a bracket body 1 and a ball joint pin 2. The ball joint pin 2 is connected to the bracket body 1. A mounting hole 14 is formed on the bracket body 1. A sealing portion 13 is formed circumferentially in the mounting hole 14. The sealing portion 13 is provided with a sealing element 3 to seal the bracket body 1 and the rear sheet metal of the vehicle body. Thus, by providing a sealing element 3 circumferentially in the mounting hole 14, the sealing element 3 forms an effective waterproof layer under bolt tightening, preventing rainwater, car wash water, etc. from entering the vehicle interior or causing sheet metal corrosion, thereby improving the sealing effect and connection stability between the bracket assembly 100 and the rear sheet metal of the vehicle body.

[0049] Understandably, the bracket body 1 is a basic structural component to facilitate installation and mating with the rear sheet metal of the vehicle body. The bracket body 1 has mounting holes 14 and ball pins 2. The mounting holes 14 are used to fix the entire bracket assembly 100 to the rear sheet metal of the vehicle body. The sealing part 13 is formed circumferentially around the mounting holes 14 and has a sealing element 3. When the bracket body 1 is fixedly connected to the rear sheet metal of the vehicle body by fasteners, the sealing element 3 is compressed and deformed, filling the gap between the bracket body 1 and the rear sheet metal of the vehicle body, thereby achieving a waterproof sealing function. Furthermore, the bracket body 1 and the rear sheet metal of the vehicle body are connected by metal-to-metal contact, so that the bracket body 1 and the rear sheet metal of the vehicle body are rigidly connected by fasteners, avoiding the loss of clamping force between the bracket body 1 and the rear sheet metal of the vehicle body, and ensuring the connection stability between the bracket body 1 and the rear sheet metal of the vehicle body.

[0050] Reference Figure 2 As shown, the bracket body 1 is provided with a ball head pin 2. One end of the ball head pin 2 is connected to the bracket body 1, and the other end of the ball head pin 2 forms a ball head. The ball head is connected to the tailgate support rod 300. The bracket body 1 is connected to the rear sheet metal of the vehicle body. The sealing part 13 is located on the side surface of the bracket body 1 facing the rear sheet metal of the vehicle body. When the bracket body 1 and the rear sheet metal of the vehicle body are fixedly connected by fasteners, the sealing element 3 in the sealing part 13 is compressed and deformed, filling the gap between the bracket body 1 and the rear sheet metal of the vehicle body. There is no gap between the bracket body 1 and the rear sheet metal of the vehicle body, thus preventing rainwater, car wash water, dust and impurities from entering the vehicle interior.

[0051] According to the embodiment of the present utility model, the bracket assembly 100 of the car rear door support rod 300, by providing a sealing element 3 in the circumferential direction of the mounting hole 14, forms an effective waterproof layer under the tightening of the bolts, preventing rainwater, car wash water, etc. from entering the car or causing sheet metal corrosion, thereby improving the sealing effect and connection stability between the bracket assembly 100 and the rear sheet metal of the car body, and enhancing the durability and comfort of the vehicle.

[0052] In some embodiments of this utility model, the sealing portion 13 is formed as a sealing groove that extends circumferentially around the mounting hole 14, and at least a portion of the sealing member 3 is located within the sealing groove. Thus, by forming a sealing groove to accommodate and confine the sealing member 3, displacement or uneven deformation of the sealing member 3 during assembly is prevented, which helps maintain the positional stability of the sealing member 3 and avoids uneven distribution of clamping force due to the sealing member 3, thereby improving the sealing performance of the connection between the bracket assembly 100 and the rear sheet metal of the vehicle body.

[0053] Reference Figures 2-4As shown, it can be understood that the sealing groove extends in a circular shape in the circumferential direction of the mounting hole 14. A portion of the sealing element 3 in the axial direction is located inside the sealing groove, and another portion of the sealing element 3 in the axial direction is located outside the sealing groove. When the bracket assembly 100 is fixed to the rear sheet metal of the vehicle body by fasteners, the sealing element 3 is completely pressed between the sealing groove and the rear sheet metal of the vehicle body, thereby realizing the sealed connection between the bracket body 1 and the rear sheet metal of the vehicle body, effectively preventing rainwater, car wash water, impurities, etc. from entering the interior of the vehicle body through the mounting hole 14.

[0054] In addition, if the seal 3 ages and fails, the seal 3 can be replaced, without replacing the entire bracket assembly 100, which reduces the maintenance difficulty and cost of the bracket assembly 100.

[0055] In some embodiments of this utility model, the sealing element 3 is switchable between a first state and a second state. When the sealing element 3 is in the first state, a portion of the sealing element 3 is located outside the sealing groove. When the sealing element 3 is in the second state, the sealing element 3 is completely located inside the sealing groove. Thus, by deformably setting the sealing element 3 inside the sealing groove, when the sealing element 3 is in the first state, a portion of the sealing element 3 is located outside the sealing groove, i.e., the sealing element 3 is not compressed and deformed. When the sealing element 3 is in the second state, the sealing element 3 is compressed and deformed. The sealing element 3 fills the gap between the bracket body 1 and the rear sheet metal of the vehicle body, forming an effective seal.

[0056] Reference Figures 3-8 As shown, it can be understood that the seal 3 has a first state and a second state, and the seal 3 can switch between the first state and the second state. When the seal 3 is in the first state, that is, the initial state of the seal 3, as shown... Figures 3-5 As shown, a portion of the seal 3 in the axial direction is located within the sealing groove. When the seal 3 is in the second state, that is, when the seal 3 is compressed and deformed, as shown... Figures 6-8 As shown, this is to achieve a reliable seal.

[0057] In some embodiments of this utility model, the axial dimension of the seal 3 is not less than the depth of the sealing groove. Therefore, in the uncompressed state (i.e., the first state), part or all of the seal 3 is above the surface of the sealing groove, thus having a certain pre-pressure during assembly. This allows the seal 3 to stably conform to the surface of the rear sheet metal of the vehicle body after being compressed, improving sealing consistency.

[0058] Reference Figure 3As shown, it is understandable that if the size of the seal 3 is too small (i.e., the axial dimension of the seal 3 is less than the depth of the sealing groove), it cannot be fully compressed, resulting in insufficient sealing force; if the size of the seal 3 is greater than or equal to the depth of the sealing groove (i.e., the axial dimension of the seal 3 is not less than the depth of the sealing groove), it can ensure that sufficient compression can be obtained even if assembly tolerances exist, thus guaranteeing the sealing effect.

[0059] In some feasible embodiments, the cross-section of the seal 3 can be rectangular, T-shaped, Y-shaped, mushroom-shaped, etc.

[0060] Optionally, the material of the seal 3 can be: EPDM rubber (ethylene propylene diene monomer rubber), silicone, TPE (thermoplastic elastomer), TPU (thermoplastic polyurethane), etc.

[0061] In some embodiments of this utility model, the mounting hole 14 includes a first hole 141 and a second hole 142, which are located on the radial sides of the ball head pin 2, respectively. Sealing grooves are formed in the circumferential direction of both the first hole 141 and the second hole 142. Thus, by providing two mounting holes 14 (i.e., the first hole 141 and the second hole 142), the bracket assembly 100 is firmly fixed to the vehicle body, enhancing the overall structural rigidity. The first hole 141 and the second hole 142, located on the radial sides of the ball head pin 2, prevent the bracket assembly 100 from deflecting or loosening due to unilateral force, ensuring the connection stability and reliability of the bracket assembly 100.

[0062] In some embodiments of this utility model, at least one of the first hole 141 and the second hole 142 is formed as an oblong hole. It is understood that in the actual manufacturing and assembly process, there may be processing errors, assembly deviations or differences in thermal expansion between the body sheet metal, the bracket body 1, and the bolt mounting positions. An oblong hole is a non-circular through hole with semi-circular ends, a rectangular middle, and an overall "oblong" or "racetrack" shape. It can be used to adjust the relative mounting position of the bracket body 1 and the rear body sheet metal. Even if there are tolerances, the bracket body 1 and the rear body sheet metal can still be installed smoothly.

[0063] Furthermore, when installing the bracket assembly 100 onto the rear sheet metal of the vehicle body, a pre-installation followed by tightening assembly process can be adopted. Initial positioning is performed first through the oblong hole, and then final fixation is completed through the round hole, which ensures the assembly qualification rate between the bracket assembly 100 and the rear sheet metal of the vehicle body and reduces assembly errors.

[0064] Reference Figure 3 As shown, the first hole 141 is formed as a circular hole, and the second hole 142 is formed as an oblong hole.

[0065] In some embodiments of this utility model, such as Figure 2As shown, the bracket body 1 has a first plate 11 and a second plate 12 connected to both sides of the first plate 11. The first plate 11 is located away from the rear sheet metal of the vehicle body. The ball head pin 2 is located on the first plate 11, and the mounting hole 14 and the sealing part 13 are both located on the second plate 12. Thus, by setting the first plate 11 and the second plate 12 which are not in the same plane, when the ball head pin 2 is under force, the ball head pin 2 transmits the force to the first plate 11. The first plate 11 is spaced apart from the rear sheet metal of the vehicle body, which plays a role in suction and buffering. The second plate 12 is rigidly connected to the rear sheet metal of the vehicle body by fasteners, which avoids the loss of clamping force between the bracket body 1 and the rear sheet metal of the vehicle body and ensures the connection stability between the bracket body 1 and the rear sheet metal of the vehicle body.

[0066] In some embodiments of this utility model, the sealing part 13 is formed on the side of the bracket body 1 facing the rear sheet metal of the vehicle body. Optionally, the sealing part 13 can also be formed as a sealing area extending around the mounting hole 14. Liquid sealant (such as silicone sealant or polyurethane sealant) can be applied to the sealing area to fill small irregular surfaces and provide a good sealing effect; or, a self-adhesive sealing strip can be provided in the sealing area; or, the sealing part 13 can be formed as a sealing groove or sealing area, and a heat-meltable sealing element 3 can be provided in the sealing part 13. The sealing element 3 is melted by heating and fills the gap. After cooling, a solid sealing layer is formed, ensuring the sealing effect.

[0067] Secondly, this utility model embodiment provides a tailgate assembly 1000, including: a tailgate body 200, a tailgate support rod 300, a rear body sheet metal, and a bracket assembly 100 for the automotive tailgate support rod 300 provided in any of the embodiments of the first aspect above, such as... Figure 1 As shown, the tailgate support rod 300 is connected to the ball head pin 2 of the bracket assembly 100, the bracket assembly 100 is connected to the rear sheet metal of the vehicle body through the mounting hole 14, and the tailgate body 200 is connected to the rear sheet metal of the vehicle body through the hinge 400.

[0068] The rear tailgate assembly 1000 provided in this embodiment of the utility model, since it includes the bracket assembly 100 of the car rear tailgate support rod 300 provided in any of the embodiments of the first aspect above, has the same technical effect, that is, by providing a sealing element 3 in the circumferential direction of the mounting hole 14, the sealing element 3 forms an effective waterproof layer under the tightening of the bolt, preventing rainwater, car wash water, etc. from entering the car or causing sheet metal corrosion, improving the sealing effect and connection stability between the bracket assembly 100 and the rear sheet metal of the car body, and improving the durability and comfort of the vehicle.

[0069] Thirdly, this utility model provides a vehicle including the tailgate assembly 1000 provided in any of the embodiments of the second aspect above.

[0070] The vehicle provided in this embodiment of the utility model, by including the tailgate assembly 1000 provided in the second aspect above, can effectively prevent rainwater, car wash water, impurities and dust from entering the vehicle body, avoid corrosion of sheet metal, improve the production quality and durability of the vehicle, and extend the service life of the vehicle.

[0071] The following reference Figures 1-8 The bracket assembly 100 of the automobile tailgate support rod 300 according to a specific embodiment of the present invention will be described.

[0072] Specifically, the bracket body 1 is provided with a ball head pin 2. One end of the ball head pin 2 is connected to the bracket body 1, and the other end of the ball head pin 2 forms a ball head. The ball head is connected to the tailgate support rod 300. The bracket body 1 is connected to the rear sheet metal of the vehicle body. The sealing part 13 is located on the side surface of the bracket body 1 facing the rear sheet metal of the vehicle body. When the bracket body 1 and the rear sheet metal of the vehicle body are fixedly connected by fasteners, the sealing element 3 in the sealing part 13 is compressed and deformed, filling the gap between the bracket body 1 and the rear sheet metal of the vehicle body. There is no gap between the bracket body 1 and the rear sheet metal of the vehicle body, thus preventing rainwater, car wash water, dust and impurities from entering the vehicle interior.

[0073] The sealing groove extends in a circular shape in the circumferential direction of the mounting hole 14. A portion of the seal 3 in the axial direction is located inside the sealing groove, and another portion of the seal 3 in the axial direction is located outside the sealing groove. The mounting hole 14 includes a first hole 141 and a second hole 142, which are located on the radial sides of the ball head pin 2, respectively. Sealing grooves are formed in the circumferential direction of both the first hole 141 and the second hole 142. The first hole 141 is a circular hole, and the second hole 142 is an oblong hole. The bracket body 1 has a first plate 11 and a second plate 12 connected to both sides of the first plate 11. The first plate 11 is located away from the rear sheet metal of the vehicle body.
