[0019] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0020] like Figures 1 to 3 A buffer pad support is shown, including a plastic body 1 with a buffer pad support surface 101 on the top, the plastic body 1 includes a top wall portion, an inner wall portion 108, an outer wall portion 104 and a plurality of rib portions 107, the top end of the inner wall portion 108 and the top end of the outer wall portion 104 are respectively connected to the top wall portion as a whole, the inner wall portion 108 surrounds a connecting hole 102 with an open bottom end, the outer wall portion 104 surrounds the periphery of the inner wall portion 108, and an annular space with an open bottom end is formed between the outer wall portion 104 and the inner wall portion 108, and a rib portion 107 connected between the inner wall portion 108 and the outer wall portion 104 is provided in the annular space.
[0021] By adopting the above-mentioned technical solution, an annular space is formed in the plastic body 1. On the one hand, it can reduce the material and weight, improve the lightweight level of the buffer pad support, and reduce the material consumption; on the other hand, the annular space can reduce the wall thickness of the plastic body 1, and the wall thickness of the outer wall 104 can be made thinner, which helps to reduce the possibility of shrinkage defects in the plastic body 1 during the injection molding process. The annular space is set as a structure with one side open, which provides convenience for manufacturing the plastic body 1 by injection molding. The rib plate portion 107 is set in the annular space to ensure the strength and rigidity of the plastic body 1.
[0022] In some embodiments, a plurality of rib portions 107 are provided in the annular space, and the plurality of rib portions 107 divide the annular space into a plurality of separated spaces 106 with open bottom ends. The plurality of rib portions 107 can better ensure the strength and rigidity of the plastic body 1. As a preferred example, the plurality of rib portions 107 are respectively arranged along a plurality of radial directions of the plastic body 1, and the plurality of rib portions 107 divide the annular space into a plurality of separated spaces 106 with fan-shaped cross sections, and the top ends of the plurality of rib portions 107 are respectively connected to the top wall as a whole, which provides convenience for manufacturing the plastic body 1 by injection molding while better ensuring the strength and rigidity of the plastic body 1.
[0023] In some embodiments, the connection hole 102 is a through hole, and a first aperture enlargement section 103 for accommodating a bolt head is provided at the top of the connection hole 102. In specific implementation, the buffer support can be fixedly connected to the vehicle body by a bolt matched with the connection hole 102, which has the characteristic of being easy to implement. The first aperture enlargement section 103 is used to accommodate the bolt head, so that the bolt head can be prevented from protruding from the buffer support surface 101, thereby ensuring that the buffer support surface 101 can better contact with the tailgate buffer.
[0024] In some embodiments, the plastic body 1 is an integrally injection-molded plastic part, which has the characteristic of being easy to implement.
[0025] In some embodiments, the buffer pad support also includes a support bottom cover 2 that is padded on the bottom of the plastic body 1. The support bottom cover 2 is provided with a through hole 301 for a fastener connected to the connecting hole 102 to pass through, and the bottom surface of the support bottom cover 2 is provided with an annular plane 303 that is arranged around the through hole 301. Since the bottom of the plastic body 1 forms a mesh structure, it is difficult to seal. By providing the support bottom cover 2, a flatter annular plane 303 with a larger sealing area can be formed by utilizing the bottom surface of the support bottom cover 2, which helps to improve the waterproof performance of the buffer pad support. The support bottom cover 2 is provided so that the seal can be better arranged between the buffer pad support and the vehicle body, which helps to ensure the sealing performance of the connection between the buffer pad support and the vehicle body. By providing the support bottom cover 2 to cover the bottom of the plastic body 1, it helps to improve the integrity of the buffer pad support structure.
[0026] In some embodiments, the support bottom cover 2 and the plastic body 1 are bonded together by an adhesive 3. Using the adhesive 3 to bond the support bottom cover 2 and the plastic body 1 together to form an assembly helps to reduce the difficulty of assembling the buffer pad support.
[0027] In some embodiments, the adhesive member 3 is annular, and a first center hole 201 is provided at the center of the adhesive member 3. The inner edge of the adhesive member 3 is clamped between the bottom end surface of the inner wall portion 108 and the support bottom cover 2, and the outer edge of the adhesive member 3 is clamped between the bottom end surface of the outer wall portion 104 and the support bottom cover 2. The above technical solution can ensure the connection stability between the support bottom cover 2 and the plastic body 1, and also help prevent water from entering between the support bottom cover 2 and the plastic body 1.
[0028] In a specific implementation, an annular shielding portion may be provided at the outer edge of the bottom end surface of the outer wall portion 104, and the annular shielding portion is used to shield the outer edge of the adhesive 3. Further, the annular shielding portion may be supported on the outer edge of the support bottom cover 2, so that the buffer pad support has a more complete appearance.
[0029] As a specific example, the adhesive member 3 is a double-sided adhesive connected between the support bottom cover 2 and the plastic body 1 .
[0030] In some embodiments, the end of the connection hole 102 near the bottom of the plastic body 1 is configured as a second aperture enlargement section 105, and the support bottom cover 2 is provided with an annular protrusion 302 extending into the second aperture enlargement section 105 and cooperating with the second aperture enlargement section 105, and the annular protrusion 302 is arranged around the through hole 301. The cooperation between the annular protrusion 302 and the second aperture enlargement section 105 can, on the one hand, play a role in assembly positioning, and help ensure the assembly accuracy between the plastic body 1 and the support bottom cover 2; on the other hand, the annular protrusion 302 can also form a water retaining structure to prevent external water from flowing into the connection hole 102.
[0031] In some embodiments, a waterproof pad 4 is connected to the annular plane 303, and the waterproof pad 4 is annular, and a second center hole 401 is provided in the center of the waterproof pad 4. The waterproof pad 4 can ensure the sealing performance of the connection between the buffer pad support and the vehicle body, and by providing the support bottom cover 2, the bottom surface of the support bottom cover 2 can be used to better flatten the waterproof pad 4, thereby ensuring the waterproof performance of the waterproof pad 4. In a specific implementation, the bottom surface of the support bottom cover 2 is an annular plane 303, and the annular plane 303 and the waterproof pad 4 are both surrounded by the outer periphery of the bolt. The waterproof pad 4 can be connected to the annular plane 303 of the support bottom cover 2 by bonding.
[0032] In some embodiments, the waterproof pad 4 is a foam member. The waterproof pad 4 made of foam has the characteristic of being light in weight. When the buffer pad support is fastened and installed on the vehicle body by the fastener, the waterproof pad 4 made of foam can provide a better seal after being compressed.
[0033] In the specific implementation, by adopting the above-mentioned plastic body 1, the restrictions on the shape of the plastic body 1 are reduced, and the shape of the plastic body 1 can be set according to the needs. For example, the plastic body 1 is in the shape of a truncated cone with a small top and a large bottom, and the support bottom cover 2 is in the shape of a disc, which can ensure the aesthetic appearance of the cushion support.
[0034] The present invention also provides a vehicle, comprising any of the above-mentioned cushion supports. In specific implementation, the cushion support can be fixedly mounted on the vehicle body by bolts passing through the connection hole 102, the first center hole 201, the through hole 301 and the second center hole 401, and the top surface of the plastic body 1 is used as the cushion support surface 101 of the back door cushion. During the use of the vehicle, the back door cushion on the back door contacts the cushion support surface 101 to play a role in buffering and shock absorption.
