Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle technology, specifically to a buffer pad support and a vehicle. Background Technology
[0002] like Figure 4 As shown, some vehicles have a buffer pad 200 installed on the tailgate 100. When the tailgate 100 is closed, the buffer pad 200 contacts the vehicle body 300, providing cushioning and shock absorption. Due to limitations in the tailgate 100 structure and the size of the buffer pad 200, when the distance between the buffer pad 200 and the vehicle body 300 is large, a boss 400 is usually added to the components of the vehicle body 300. The top surface of the boss 400 contacts the buffer pad 200 to provide cushioning and shock absorption. When the height of the boss 400 is large, the stamping and forming of the boss 400 becomes more difficult, negatively impacting the product qualification rate and material utilization rate of the vehicle body components. To ensure the product qualification rate and material utilization rate of the vehicle body components, some vehicles have a buffer pad support installed on the vehicle body. The top surface of the buffer pad support contacts the buffer pad 200 to provide cushioning and shock absorption. For example, patent application CN103863069A discloses a buffer pad support suitable for passenger car tailgates.

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.
[0027] 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.
[0028] like Figures 1 to 3 The buffer pad support shown includes 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 ends of the inner wall portion 108 and the outer wall portion 104 are respectively connected to the top wall portion as a whole. The inner wall portion 108 forms a connecting hole 102 with an open bottom end. The outer wall portion 104 surrounds the outer periphery of the inner wall portion 108. An annular space with an open bottom end is formed between the outer wall portion 104 and the inner wall portion 108. Rib portions 107 connecting the inner wall portion 108 and the outer wall portion 104 are provided in the annular space.
[0029] With the technical scheme, the annular space is formed in the plastic body 1, on one hand, the annular space can play a subtractive and weight-reducing role, and the light weight level of the cushion support is improved, and the material consumption is reduced; 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 portion 104 can be made thinner, which helps to reduce the possibility of shrinkage defects of the plastic body 1 in the process of injection molding. The annular space is arranged as an open structure on one side, which provides convenience for manufacturing the plastic body 1 by using the injection molding method. The rib plate portion 107 is arranged in the annular space, which can ensure the strength and rigidity of the plastic body 1.
[0030] In some embodiments, a plurality of rib plate portions 107 are arranged in the annular space, and the plurality of rib plate portions 107 separate the annular space into a plurality of open-bottom separated spaces 106. The plurality of rib plate portions 107 can better ensure the strength and rigidity of the plastic body 1. As a preferred example, the plurality of rib plate portions 107 are arranged along a plurality of radial directions of the plastic body 1, the plurality of rib plate portions 107 separate the annular space into a plurality of separated spaces 106 with a fan-shaped cross section, and the top ends of the plurality of rib plate portions 107 are integrally connected with the top wall portion. This arrangement can better ensure the strength and rigidity of the plastic body 1, and provides convenience for manufacturing the plastic body 1 by using the injection molding method.
[0031] In some embodiments, the connecting hole 102 is a through hole, and a first hole diameter expansion section 103 for accommodating a bolt head is arranged at the top end of the connecting hole 102. In specific implementation, a bolt matched with the connecting hole 102 can be used to fixedly connect the cushion support to the vehicle body, which has the characteristic of easy implementation. The bolt head can be accommodated by the first hole diameter expansion section 103, which can prevent the bolt head from protruding from the cushion support surface 101, thereby ensuring that the cushion support surface 101 can better contact the back door cushion.
[0032] In some embodiments, the plastic body 1 is an integrally injection molded plastic part, which has the characteristic of easy implementation.
[0033] In some embodiments, the cushion support further includes a support bottom cover 3 arranged on the bottom of the plastic body 1, and a via hole 301 for passing a fastener connected with the connecting hole 102 is arranged on the support bottom cover 3, and an annular plane 303 surrounding the via hole 301 is arranged on the bottom surface of the support bottom cover 3. Since the bottom of the plastic body 1 forms a mesh structure, it is difficult to seal. By arranging the support bottom cover 3, the bottom surface of the support bottom cover 3 can form a more flat and larger sealing area annular plane 303, which helps to improve the waterproof performance of the cushion support. The arrangement of the support bottom cover 3 enables the cushion support and the vehicle body to better arrange a sealing member, which helps to ensure the sealing performance of the connection between the cushion support and the vehicle body. The arrangement of the support bottom cover 3 covers the bottom of the plastic body 1, which helps to improve the integrity of the structure of the cushion support.
[0034] In some embodiments, the support bottom cover 3 and the plastic body 1 are bonded together by the bonding member 2. Bonding the support bottom cover 3 and the plastic body 1 together by the bonding member 2 forms an assembly, which helps to reduce the assembly difficulty of the cushion support.
[0035] In some embodiments, the bonding member 2 is annular, the center of the bonding member 2 is provided with a first center hole 201, the inner edge of the bonding member 2 is clamped between the bottom end surface of the inner wall portion 108 and the support bottom cover 3, and the outer edge of the bonding member 2 is clamped between the bottom end surface of the outer wall portion 104 and the support bottom cover 3. With the above technical solution, the connection stability between the support bottom cover 3 and the plastic body 1 can be ensured, and water between the support bottom cover 3 and the plastic body 1 can be prevented.
[0036] In specific implementation, an annular shielding portion can be arranged on the outer edge of the bottom end surface of the outer wall portion 104 to shield the outer edge of the bonding member 2. Further, the annular shielding portion can be supported on the outer edge of the support bottom cover 3 to make the cushion support have a more complete appearance.
[0037] As a specific example, the bonding member 2 is double-sided tape connected between the support bottom cover 3 and the plastic body 1.
[0038] In some embodiments, the connecting hole 102 is arranged as a second hole diameter expansion section 105 at the end of the bottom side of the plastic body 1, the support bottom cover 3 is provided with an annular protrusion 302 extending into the second hole diameter expansion section 105 and cooperating with the second hole diameter expansion section 105, and the annular protrusion 302 is arranged around the hole 301. By cooperating the annular protrusion 302 with the second hole diameter expansion section 105, on the one hand, the assembly positioning function can be achieved, which helps to ensure the assembly precision between the plastic body 1 and the support bottom cover 3; on the other hand, the annular protrusion 302 can also form a water blocking structure to prevent water from the outside from flowing into the connecting hole 102.
[0039] In some embodiments, a waterproof pad 4 is connected to the annular plane 303, the waterproof pad 4 is annular, and the waterproof pad 4 is provided with a second center hole 401. The waterproof pad 4 can ensure the sealing performance of the connection between the cushion support and the vehicle body. By arranging the support bottom cover 3, the bottom surface of the support bottom cover 3 can better flatten the waterproof pad 4 to ensure the waterproof performance of the waterproof pad 4. In specific implementation, the bottom surface of the support bottom cover 3 is the annular plane 303, and the annular plane 303 and the waterproof pad 4 are both arranged around the bolt. The waterproof pad 4 can be connected to the annular plane 303 of the support bottom cover 3 by bonding.
[0040] In some embodiments, the waterproof pad 4 is a foam piece. The waterproof pad 4 made of foam has the feature of light weight, and when the cushion support is fastened to the vehicle body by the fastener, the waterproof pad 4 made of foam can provide better sealing after being compressed.
[0041] In specific implementation, by using the plastic body 1 described above, the limitation on the shape of the plastic body 1 is reduced, and the shape of the plastic body 1 can be set according to requirements. For example, the plastic body 1 as a whole is in the shape of a circular truncated cone with a small upper part and a large lower part, and the support bottom cover 3 is in the shape of a disc, which can ensure the aesthetic appearance of the cushion support.
[0042] The application also provides a vehicle comprising the cushion support described in any one of the above. In specific implementation, the cushion support can be fixedly installed on the vehicle body by using a bolt passing through the connecting hole 102, the first center hole 201, the via 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. In the use of the vehicle, the back door cushion on the back door contacts the cushion support surface 101 to play a role of buffering and shock absorption.
