Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive technology, specifically to a semi-concealed outward-opening door handle structure and an automobile. Background Technology
[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.
[0003] With the development of the automotive industry, cars need to meet more and more scenario requirements, resulting in a wide variety of handle shapes and functions on the market. Regarding the waterproof sealing of handles, current handles on the market mainly achieve this through the handle's placement height. By placing the handle above the vehicle's wading line, the risk of water ingress is reduced, thus preventing water from entering the handle. Alternatively, a sealing ring is placed in the groove of the handle's mounting base, and this sealing ring adheres to the door sheet metal to achieve the purpose of waterproof sealing.
[0004] The aforementioned solution of raising the handle height does not provide waterproofing; if the water level rises to the handle's position, water will still seep in. The solution of using a sealing ring in the handle's mounting recess only meets rain requirements; if the handle is completely submerged, a large amount of water will enter, failing to meet the requirements for water immersion during navigation. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a semi-concealed outward-opening handle structure and automobile that can seal all water inlet points of the handle structure, thus overcoming the defects of the current semi-concealed outward-opening handle.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, embodiments of the present invention provide a semi-concealed outward-opening handle structure, including a handle base, a handle recess inside the handle base, a sealing base fixed to the handle base on the outer periphery of the handle recess, and a handle, including a handle handle and a connecting arm fixed to the inner side of the handle handle. The connecting arm passes through the handle recess and the top of the handle base and is rotatably connected to a rotating shaft provided on the top of the handle base. An elastic element is provided between the connecting arm and the rotating shaft. A first sealing element is provided on the side of the sealing base that is used to cooperate with the door sheet metal. A second sealing element is provided between the sealing base and the outer periphery of the handle recess. A third sealing element is provided in the area of the handle recess that is used to contact the handle in the closed state.
[0007] Optionally, the first sealing element is an annular sealing ring fixed to the outer side of the sealing base, and the sealing ring is a closed-cell foam sealing ring.
[0008] Optionally, the closed-cell foam sealing ring is formed by integrally connecting and surrounding multiple closed-cell foam sealing strips corresponding to the sealing base. The width of the closed-cell foam sealing strip is 5.5mm-6mm, preferably 7mm, and the thickness is 6mm-8mm, preferably 7mm.
[0009] Optionally, the second seal is a sealing rubber disposed between the sealing base and the outer edge of the handle socket.
[0010] Optionally, the sealing soft adhesive is fixedly connected to the sealing base, and the sealing soft adhesive and the sealing base are formed by a two-stage injection molding process.
[0011] Optionally, the handle includes a handle, and the inner side of the handle is provided with a connecting seat, which is fixedly connected to the bottom end of the connecting arm.
[0012] Optionally, the second sealing element includes a first sealing strip and a second sealing strip arranged in parallel. The first sealing strip can seal against the upper edge of the handle, and the second sealing strip can seal against the inner side of the connecting seat. A third sealing strip is provided between the two side ends of the first and second sealing strips. The third sealing strip is used to seal against the side ends of the handle and the side of the connecting seat.
[0013] Optionally, the first sealing strip, the second sealing strip, and the third sealing strip are all closed-cell foam sealing strips.
[0014] Optionally, the width of the closed-cell foam sealing strip is 4.5mm-5.5mm, preferably 5mm, and the thickness is 5mm-7mm, preferably 6mm.
[0015] Secondly, embodiments of the present invention provide a car equipped with the semi-concealed outward-opening handle structure described in the first aspect.
[0016] The beneficial effects of this invention are as follows: The semi-concealed outward-opening handle structure of the present invention includes a first sealing element, a second sealing element, and a third sealing element. The first sealing element can seal the space between the sealing base and the door sheet metal, the second sealing element can seal the space between the handle recess and the sealing base, and the third sealing element can seal the space between the handle and the handle recess when the handle is closed. Therefore, the entire water inlet position of the handle can be sealed, and the handle structure still has a good sealing effect when it is submerged in water, which meets the usage requirements of a car in a submerged state. Compared with the existing semi-concealed outward-opening handle structure, only the second and third sealing elements are added, and the rest of the handle structure is not modified. The improvement is small, simple, and low in cost. Attached Figure Description

Detailed Implementation
[0019] Example 1 This embodiment provides a semi-concealed outward-opening handle structure, which is an improvement on the current semi-concealed outward-opening handle structure, such as... Figures 1-4As shown, the semi-concealed outward-opening handle structure includes a handle base 1, which adopts a shell structure with an open outer side. The handle base 1 has an internal cavity for accommodating a handle recess 2. Two fixing members are provided at the top and bottom of the handle base 1. The handle base 1 can be installed on the inner side of the door sheet metal via the fixing members and a tolerance adjuster. The method of fixing the handle base 1 to the inner side of the door sheet metal using a tolerance adjuster is readily available and will not be described in detail here. A sealing base 3 is fixed along the edge of the outer side of the handle base 1. The sealing base 3 is an annular structure. The handle recess 2 is fixed within the internal cavity of the handle base 1. The handle recess 3 also adopts a shell structure that matches the internal cavity of the handle base 1, with an open outer side. The sealing base 3 is located on the outer periphery of the outer edge of the open side of the handle recess 2. The handle also includes a handle 4 and a connecting arm 5 fixed inside the handle 4. Specifically, a connecting seat 6 is provided on the inner side of the handle 4. The connecting arm 5 is fixedly connected to the bottom end. The connecting seat 6 and the handle 4 are both located inside the cavity of the handle socket 3. The top shell wall of the handle socket 3 and the handle base 1 has an opening. After the connecting arm 5 passes through the opening, it is rotatably connected to the rotating shaft located at the top of the handle base 1. Both ends of the rotating shaft are fixedly connected to the rotating shaft seat. The rotating shaft seat and the handle base 1 are integrally connected. In this embodiment, there are two connecting arms 5. When the user turns the handle, the handle 4 moves away from the handle socket 2. The connecting arm 5 drives the entire handle to rotate, which can open the handle. An elastic element is provided between the rotating shaft and the connecting arm. The elastic element is used to reset the entire handle, so that the handle 4 and the connecting seat 6 are put into the cavity of the handle socket, so that the handle is kept in the closed state. Preferably, the elastic element is a torsion spring 7 set between the connecting arm and the rotating shaft. The torsion spring 7 can apply an elastic force to the handle, so that the handle is always kept in the closed state in the natural state. The handle can only be opened when the user applies external force.
[0020] The above structure can be achieved using the current semi-concealed outward-opening handle structure, and its further technical details will not be described in detail here.
[0021] One side of the sealing base 3 is fixedly connected to the handle base 1, and the other side, which is used to cooperate with the inner side of the door sheet metal, is fixed with a first sealing element 8. The first sealing element 8 is used to be disposed between the sealing base 3 and the inner side of the door sheet metal. The first sealing element 8 is sealed and fitted with the inner side of the door sheet metal to achieve a seal between the door sheet metal and the sealing base 3.
[0022] In this embodiment, the first sealing element 8 adopts an annular sealing ring that matches the sealing base 3. The sealing ring adopts a closed-cell foam sealing ring. Since the sealing base 3 is a rectangular annular structure, the closed-cell foam sealing ring is formed by four closed-cell foam sealing strips integrally connected and enclosed. Each closed-cell foam sealing strip is fixed to the outer edge of the corresponding sealing base 3.
[0023] In the closed-cell foam sealing ring, the width of each closed-cell foam sealing strip is 5.5mm-6mm, preferably 7mm, and the thickness is 6mm-8mm, preferably 7mm.
[0024] After the handle base 1 is fixed to the door sheet metal, the closed-cell foam sealing ring can be squeezed and compressed by the inner side of the door sheet metal, so that the closed-cell foam sealing ring is sealed and fitted to the inner side of the door sheet metal, thus achieving a seal between the sealing base 3 and the door sheet metal.
[0025] The first sealing element uses a closed-cell foam sealing ring, which is bonded and fixed to the outer side of the sealing base 3. The closed-cell foam material has extremely low water absorption and moisture permeability, and can maintain stable performance even after long-term immersion or in a high-humidity environment. It has good pressure resistance and cushioning protection capabilities. Since the closed-cell bubble structure can effectively prevent heat conduction, the first sealing element has high-efficiency heat insulation performance, excellent chemical stability and durability, and long service life. Moreover, the closed-cell foam material has low density and light weight, which will not increase the overall weight load of the handle structure.
[0026] It is understood that the first sealing element may also be made of flexible sealing materials such as rubber sealing rings or silicone sealing rings. Those skilled in the art can set it according to actual needs, and it will not be described in detail here.
[0027] A second sealing element 9 is provided between the sealing base 3 and the outer edge of the open side of the handle socket 2, for sealing the sealing base 3 and the handle socket 2.
[0028] In this embodiment, the second seal 9 is a sealing soft rubber filled between the sealing base 3 and the outer edge of the open side of the handle socket 2.
[0029] The sealing soft rubber is fixed to the sealing base 3, and is integrally molded with the sealing base 3 by a secondary injection molding process.
[0030] It is understood that the second sealing element 9 may also be a rubber sealing ring or a silicone sealing ring, etc. Those skilled in the art can choose according to actual needs, and will not be described in detail here.
[0031] The handle recess 2 is provided with a third seal for the area that contacts the handle in the closed state, so that the gap between the handle 4 and the connecting seat 6 and the handle recess 2 can be sealed when the handle is in the closed state.
[0032] In this embodiment, when the handle is in the closed state, the upper edge of the inner side of the handle 4 will contact the handle socket 2, the two ends of the handle 4 will contact the handle socket 2, and the inner end face and two sides of the connecting seat 6 will contact the handle socket 2. Therefore, the third sealing element includes a first sealing strip 10 and a second sealing strip 11 arranged in parallel. The first sealing strip 10 is fixed on the area where the handle socket 2 contacts the upper edge of the inner side of the handle 4, and the second sealing strip 11 is fixed on the area where the handle socket 2 contacts the inner end face of the connecting seat 6. A third sealing strip 12 is provided between the two ends of the first sealing strip 10 and the second sealing strip 11. The third sealing strip 12 is provided on the area where the handle socket 2 contacts the inner end face of the handle 4 and the two sides of the connecting seat 6.
[0033] The first sealing strip 10, the second sealing strip 11, and the third sealing strip 12 are integrally connected to form the third sealing element.
[0034] When the handle is in the closed state under the action of the torsion spring 7, the upper edge of the inner side of the handle 4 is sealed and fitted with the first sealing strip 10, the inner end face of the connecting seat 6 is sealed and fitted with the second sealing strip 11, and the end of the inner side of the handle 4 and the inner side of the connecting seat 6 are sealed and fitted with the third sealing strip 12, thereby realizing the sealing of the gap between the handle and the handle recess in the closed state by using the third sealing element.
[0035] In this embodiment, the first sealing strip 10, the second sealing strip 11, and the third sealing strip 12 are all closed-cell foam sealing strips. The width of the closed-cell foam sealing strip of the third sealing element is 4.5mm-5.5mm, preferably 5mm, and the thickness is 5mm-7mm, preferably 6mm. The first sealing strip, the second sealing strip, and the third sealing strip are all bonded and fixed to the surface of the handle recess.
[0036] It is understood that the first, second, and third sealing strips can also be made of flexible sealing materials such as rubber or silicone. Those skilled in the art can set them according to actual needs, and will not be described in detail here.
[0037] This embodiment only adds a first seal 8, a second seal 9, and a third seal to the existing semi-concealed outward-opening handle structure. The remaining structures of the handle structure that are not described in detail can be achieved using existing technologies, and will not be described in further detail here.
[0038] In this embodiment, the handle structure features a first seal 8 that seals the sealing base 3 and the door sheet metal, preventing water from entering through the gap between them. A second seal 9 seals the handle recess 2 and the sealing base 3, also preventing water from entering through the gap. A third seal seals the handle and handle recess 2 when the handle is closed, preventing water from entering through the gap between them. Therefore, all water ingress points on the handle are sealed, maintaining a good sealing effect even when the handle structure is submerged. Even when the entire handle structure is submerged, only a small amount of water will enter, meeting the usage requirements of a car in a submerged state. Furthermore, compared to existing semi-concealed outward-opening handle structures, only the second and third seals are added, without altering the rest of the handle structure. This results in a small, simple, and low-cost improvement.
[0039] For the verification of the waterproof sealing structure of the semi-concealed outward-opening handle structure in this embodiment, the handle structure was assembled on a simulated sheet metal fixture, and the handle structure was completely submerged underwater. The distance between the upper part of the handle structure and the sheet metal structure was 200mm underwater, and the immersion time was 40 minutes. After the test, the water ingress was about 2.6L. Then, a simulated rain test was conducted, with water sprayed at four angles of 0°, 30°, 60°, and 90° on each surface of the handle structure, with a flow rate of 15mm / min to 22.5mm / min and a spray pressure of 0.2Mpa±0.05, for 30 minutes. After the rain test, a 20-minute immersion test was conducted, and the water ingress was 1.3L. Finally, a simulated rain test was conducted, with water sprayed at four angles of 0°, 30°, 60°, and 90° on each surface of the outer handle, with a flow rate of 15mm / min to 22.5mm / min and a spray pressure of 0.2Mpa±0.05, for 40 minutes. No water entered the handle structure. After the above 2-hour verification, it was found that the handle is completely waterproof in rainy conditions, with less than 4L of water entering after one hour of immersion, which meets the vehicle's requirement that the water entering the door should be less than 9L after 2 hours of driving.
[0040] Example 2 This embodiment provides a car, which is a car with a semi-concealed outward-opening handle structure as described in Embodiment 1. The rest of the car structure can be constructed using existing technology and will not be described in detail here.
[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
