Description

Technical Field

[0001] The utility model relates to the technical field of hidden door handles, in particular to a sealing structure of a hidden door handle and a vehicle. Background Art

[0002] Hidden door handle technology is an emerging automotive design technology that uses sensors and motors. When the sensor does not sense the need to open the door from outside the car, the handle will be hidden inside the door, greatly improving the overall streamlined appearance of the vehicle. However, the structure of the hidden door handle is bound to bring risks to the airtightness of the entire vehicle.

[0003] For example, patent document CN215632338U discloses a sealing structure for a hidden door handle of an automobile. The sealing structure has foam bonded only at the gap. The foam will become inelastic after repeated compression and is generally not commonly used for sealing small spaces. In addition, the foam is bonded by adhesive backing, which easily provides shear force during the compression of the rocker arm, thereby causing the bonding to fail.

[0004] Therefore, it is necessary to develop a sealing structure and a vehicle of a new hidden door handle. Summary of the invention

[0005] The utility model aims to provide a sealing structure of a hidden door handle and a vehicle, which can prevent external water, dust and the like from entering the interior of the vehicle door, and the whole vehicle has good air tightness.

[0009] Optionally, a sealing plane for fitting with the door handle frame is provided on the second sealing lip. Compared with the traditional U-shaped lip interference fit solution, since the U-shaped sealing plane is less likely to deform at low temperatures, the problem of poor return of the hidden door handle under extreme working conditions (such as low temperatures) can be improved by providing a sealing plane.

[0010] Optionally, the first sealing lip is arranged on the edges of the outer side of the first sealing body, and the first sealing lip is abutted against the inner side of the vehicle door outer panel, thereby achieving sealing.

[0011] Optionally, a drainage hole is provided on the first sealing lip for drainage. When a small amount of rainwater accumulates inside the hidden door handle, the rainwater can be promptly drained out of the vehicle through the drainage hole, thereby avoiding other faults caused by rainwater accumulation.

[0012] Optionally, the drainage hole is formed on the lower part of the first sealing lip, so that rainwater accumulated inside the hidden door handle can be quickly drained out of the vehicle.

[0013] Optionally, a plurality of first claws are provided on the inner side of the first sealing body, and the first sealing gasket is clamped on the handle base through the first claws thereon, thereby achieving the installation of the first sealing body.

[0014] Optionally, a plurality of second claws are provided on the inner side of the second sealing body; the second sealing gasket is clamped on the handle base through the second claws thereon, thereby achieving the installation of the second sealing body.

[0015] Optionally, the first sealing body is made of a hard rubber material, the first sealing lip is made of an elastic soft rubber material, and the first sealing body and the first sealing lip are formed by two-color injection molding.

[0016] Optionally, the second sealing body is made of a hard rubber material, the second sealing lip is made of an elastic soft rubber material, and the second sealing body and the second sealing lip are formed by two-color injection molding. The second sealing body is made of a hard rubber material, which can meet installation requirements, and the second sealing lip is made of an elastic soft rubber material, which can meet sealing requirements.

[0017] In a second aspect, a car described in the utility model adopts the sealing structure of the hidden door handle described in the utility model.

[0018] The beneficial effects of the utility model are as follows: when the hidden door handle is hidden in the vehicle door, the first sealing lip is in interference fit with the vehicle door outer panel, thereby achieving the first level of sealing between the hidden door handle and the vehicle door outer panel, which can effectively prevent external water and dust from entering the interior of the vehicle door, thereby achieving the purpose of waterproofing and dustproofing. At the same time, the door handle frame cooperates with the second sealing gasket to perform self-sealing, thereby achieving the second level of sealing, which can further enhance the waterproofing and dustproofing capabilities of the sealing structure. Therefore, after using the sealing structure of the hidden door handle described in the utility model, the advantage of better airtightness can be achieved.

DETAILED DESCRIPTION

[0026] The following will refer to the accompanying drawings and preferred embodiments to illustrate the implementation of the technical solution of the utility model. Those skilled in the art can easily understand other advantages and effects of the utility model from the contents disclosed in this specification. The utility model can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the utility model. It should be understood that the preferred embodiments are only for illustrating the utility model, not for limiting the scope of protection of the utility model.

[0027] Traditional car door handles protrude outside the car door. On the one hand, it will have a certain adverse effect on the side wind resistance of the whole car, and on the other hand, it will affect the overall appearance of the car. Therefore, car door handles are often designed to be hidden. However, when the existing hidden door handles are in use, water and dust from the outside will enter the interior of the car door through the gap between the door handle and the outer panel of the car door, increasing the failure rate of the car door and affecting the normal use of the car door. In order to solve the above problems, in the prior art (such as a hidden door handle sealing structure disclosed in patent document CN216949935U), a sealing body is provided on one side of the handle body, and a first sealing ear piece and a second sealing ear piece are provided on the sealing body. The first sealing ear piece is in contact with the outer panel, and the second sealing ear piece can be in contact with the handle body; when the handle body is set in the door body, the second sealing ear piece is in contact with the handle body. When the handle body is hidden in the car door, the first sealing ear piece is fitted with the outer panel, and the second sealing ear piece is fitted with the handle body, so that a barrier is formed between the sealing body and the handle body and between the sealing body and the outer panel, which can prevent external water, dust, etc. from entering the interior of the car door, so as to achieve the purpose of waterproof and dustproof. However, in actual use, the second sealing ear piece cannot contact the handle, and a certain gap must be left between the two (that is, the second sealing ear piece cannot actually play a good sealing role), and a local overlapping area can appear at the rear of the shaft, and the remaining areas must be staggered, otherwise it will cause abnormal noise when the handle is unfolded and retracted, and even cause the handle to be unable to return to its original position. In addition, the sealing body is made of the same material, which is not conducive to the assembly of the sealing gasket and the handle base, and the drainage structure is not considered. The hidden door handle is prone to water and sediment, and even causes the internal structure to rust, affecting the function. In addition, the sealing structure of the hidden door handle does not consider the sealing structure at the door handle frame, which is also a part that is easily ignored and has a greater impact on the airtightness of the entire vehicle.

[0028] like Figure 5 and Figure 6 As shown, in order to solve the above problems, in an embodiment of the present application, a sealing structure of a hidden door handle includes a first sealing gasket 2 and a second sealing gasket 6.

[0029] like Figure 5 As shown, in the embodiment of the present application, the first sealing gasket 2 includes a first sealing body 21, and a first sealing lip 23 for fitting with the vehicle door outer panel 1 is provided on the outer side surface of the first sealing body 21. The first sealing lip 23 is arranged on the edges around the outer side surface of the first sealing body 21, and abuts against the inner side of the vehicle door outer panel 1 through the first sealing lip 23, that is, after installation, the first sealing lip 23 and the vehicle door outer panel 1 are interference fit.

[0030] In the embodiment of the present application, the first sealing body 21 and the first sealing lip 23 are formed by two-color injection molding. The first sealing body 21 is made of hard rubber material to meet installation requirements. The first sealing lip 23 is made of elastic soft rubber material to meet sealing requirements.

[0031] like Figure 2 and Figure 5 As shown, in the embodiment of the present application, two drainage holes 22 are provided on the first sealing lip 23 for drainage. When a small amount of rainwater accumulates inside the hidden door handle, the rainwater can be promptly drained to the outside of the vehicle through the drainage holes 22, thereby avoiding other faults caused by rainwater accumulation. Preferably, the drainage holes 22 are provided on the lower part of the first sealing lip 23; rainwater accumulated inside the hidden door handle can be quickly drained to the outside of the vehicle.

[0032] like Figure 3 As shown, in the embodiment of the present application, a plurality of first claws 24 are provided on the inner side of the first sealing body 21, and the first sealing gasket 2 is clamped on the handle base 4 through the first claws 24 thereon, thereby realizing the installation of the first sealing body 21. The number of the first claws 24 is set according to actual needs.

[0033] like Figure 6 As shown, in the embodiment of the present application, the second sealing gasket 6 includes a second sealing body 61, and a second sealing lip 62 is provided on the outer side of the second sealing body 61. The second sealing body 61 and the second sealing lip 62 are formed by two-color injection molding. Among them, the second sealing body 61 is made of hard rubber material, which can meet the installation requirements, and the second sealing lip 62 is made of elastic soft rubber material, which can meet the sealing requirements.

[0034] like Figure 6 As shown, in the embodiment of the present application, a sealing plane 62-1 that cooperates with the door handle frame 5 is provided on the second sealing lip 62; compared with the traditional U-shaped lip interference fit solution, the U-shaped sealing plane 62-1 is not easy to deform at low temperatures, so by setting the sealing plane 62-1, the problem of poor return of the hidden door handle under extreme working conditions (such as low temperature) can be improved.

[0035] like Figure 3 As shown, in the embodiment of the present application, a plurality of second claws 63 are provided inside the second sealing body 61; the second sealing gasket 6 is clamped on the handle base 4 through the second claws 63 thereon, thereby realizing the installation of the second sealing body 61. The number of the second claws 63 is set according to actual needs.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, in the embodiment of the present application, a door outer panel 1 is provided on the door body, and the hidden door handle can be movably arranged in the door body and can extend out of the door outer panel 1. When the hidden door handle is hidden in the door, the first sealing lip 23 is interference-fitted with the door outer panel 1, thereby realizing the first-level sealing between the hidden door handle and the door outer panel 1, which can effectively prevent external water and dust from entering the interior of the door, so as to achieve the purpose of waterproofing and dustproofing. At the same time, the door handle skeleton 5 cooperates with the second sealing gasket 6 to perform self-sealing, thereby realizing the second-level sealing, which can further enhance the waterproofing and dustproofing capabilities of the sealing structure. Therefore, the sealing structure of the hidden door handle can achieve the advantage of better airtightness.

[0037] In an embodiment of the present application, a vehicle adopts the sealing structure of the hidden door handle as described in the embodiment of the present application.

[0038] The above-mentioned embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above-mentioned embodiments. Any other changes, modifications, substitutions, combinations and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement modes and shall be included in the protection scope of the present invention.
