Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a door lock assembly, a door, and a vehicle. Background Technology

[0002] The car door includes the door sheet metal and the door lock assembly fixed to the door sheet metal. The lock body of the door lock assembly is provided with a fish mouth, and the door frame is provided with a latch. The door can be locked and unlocked by the engagement and disengagement of the latch and the fish mouth.

[0003] Due to the design of the fish mouth opening, if it cannot be effectively sealed, dust in the door cavity area may enter the fish mouth opening after prolonged use, causing dust accumulation. Some dust may even enter the dust accumulation area of ​​the door (between the first and second sealing strips) through the gap between the lock body and the door sheet metal, affecting the user experience. The existing sealing components used for the fish mouth opening are relatively complex and costly.

[0004] How to effectively seal the fish mouth opening to ensure dust prevention, improve user experience, and simplify the overall structure is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a door lock assembly, a door, and a vehicle that can effectively seal the fish mouth opening, ensuring dustproof performance, improving user experience, and simplifying the overall structure.

[0006] To solve the above-mentioned technical problems, this application provides a door lock assembly, including a lock body and a sealing assembly; the lock body is provided with a fish mouth opening; the sealing assembly includes a main seal and a sealing part that are independent of each other, the main seal can cover the area above the fish mouth opening, one side of the sealing part is disposed along the bottom edge of the fish mouth opening, and the other side of the sealing part is fitted with the main seal.

[0007] Optionally, the sealing part includes a first sealing member and a second sealing member, wherein the first sealing member is disposed along the bottom edge of the fish mouth opening, and the second sealing member extends along the side edge of the fish mouth opening.

[0008] Optionally, the end of the second seal that is away from the first seal extends beyond or is aligned with the top edge of the fish mouth.

[0009] Optionally, the sealing part further includes a third sealing element, which is connected to the end of the second sealing element away from the first sealing element, and the end of the third sealing element away from the second sealing element is in contact with the main seal.

[0010] Optionally, the distance between the first seal and the bottom edge of the fish mouth is in the range of 0.5mm-4mm, and the distance between the second seal and the side edge of the fish mouth is in the range of 0.5mm-4mm.

[0011] Optionally, the contact length between the main seal and the sealing part is not less than 2 mm.

[0012] Optionally, the thickness of the main seal is greater than the thickness of the sealing portion.

[0013] Optionally, the width of the main seal is greater than its height, and the width of the sealing portion is greater than its height;

[0014] And / or, both the first seal and the second seal are sealing sponges.

[0015] This application also provides a vehicle door, including the door lock assembly described above.

[0016] This application also provides a vehicle including at least one of the door lock assembly described above and the door described above.

[0017] The door lock assembly, door, and vehicle provided in this application have the following technical advantages compared to the prior art:

[0018] When installed, the main seal is sandwiched between the lock body and the door sheet metal, and can seal from the area above the fish mouth opening to prevent water or dust from the vehicle window from falling into the gap between the lock body and the door sheet metal, thereby preventing water or dust from entering the fish mouth opening or even the dust accumulation area of ​​the door.

[0019] One side of the sealing part is set along the bottom edge of the fish mouth, and the other side of the sealing part is fitted with the main seal, so that the main seal and the sealing part can form a sealing area around the lock body. The fish mouth is located in this sealing area. In this way, dust in the door cavity area can be effectively isolated from entering the fish mouth, thereby avoiding dust accumulation in the fish mouth and the dust accumulation area of ​​the door caused by this path, and improving the user experience.

[0020] In other words, this sealing assembly can prevent water or dust from the vehicle doors and windows from reaching the fish mouth opening through the main seal, and also isolate the door cavity area from the fish mouth opening through the fit between the main seal and the sealing part, preventing dust in the door cavity area from entering the fish mouth opening. Furthermore, since the sealing part does not independently seal the fish mouth opening, but rather works in conjunction with the main seal, this simplifies the overall structure and reduces costs compared to a solution that uses a separate main seal and a sealing part to ensure the fish mouth opening's seal independently.

[0021] The main seal needs to achieve waterproof and dustproof effects, requiring a large compression capacity when installed. It has relatively high versatility across different car models. The sealing part mainly serves to fill the dust at the edge of the fish mouth opening, preventing dust from entering the dust accumulation area of ​​the door and preventing large gaps between the lock body and the door sheet metal that would affect the user experience. Therefore, the compression capacity of this sealing part is relatively small when installed, and different sealing parts may be required for different car models. Since both the main seal and the sealing part are sandwiched between the lock body shell and the door sheet metal, the versatility of the main seal is higher than that of the sealing part.

[0022] The main seal can be set as a standard part, and some models can share the same main seal. The sealing part can be selected according to the specific needs of different models. Therefore, the main seal and the sealing part are two independent sealing parts. Compared with the solution of setting the main seal and the sealing part as an integrated structure, it can improve the selection flexibility of the sealing component and effectively reduce the cost of the sealing component.

[0029] 3. Door sheet metal work. Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This application provides a door lock assembly, a car door, and a vehicle. The vehicle includes a car door and a door frame. The car door includes a car door sheet metal 3 and a door lock assembly disposed on the car door sheet metal 3. The door lock assembly is installed on the inner side of the car door sheet metal 3. The door lock assembly includes a lock body 1 with a fish mouth 11. The door frame is provided with a latch. When the latch is inserted into the fish mouth 11, the car door and the door frame are in a locked state. When the latch is removed from the fish mouth 11, the car door is in an unlocked state.

[0032] like Figure 1 As shown, the lock body 1 includes a first wall portion 12 and a second wall portion 13, both of which are fixed to the door sheet metal 3. The first wall portion 12 has a mounting surface 121 with first mounting holes 122, and is connected to the mounting side of the door sheet metal 3 via fasteners. The first wall portion 12 refers to the side wall portion facing the door frame in the installed state. The second wall portion 13 refers to the side wall portion facing the interior of the vehicle, and has multiple spaced second mounting holes 131, which are fixed to the door sheet metal 3 via multiple spaced fasteners. The first wall portion 12 and the second wall portion 13 are arranged at an angle, the specific angle of which can be matched to the structure of the corresponding door sheet metal 3. A fish-mouth opening 11 is located at the bend of the first wall portion 12 and the second wall portion 13, and extends through both the first wall portion 12 and the second wall portion 13.

[0033] Due to the design of the fish-mouth opening 11, dust in the door cavity area may enter the fish-mouth opening 11 after prolonged use, causing dust accumulation at the fish-mouth opening 11. Some dust may even enter the dust accumulation area of ​​the door (between the first and second sealing strips) through the gap between the lock body 1 and the door sheet metal 3, affecting the user experience. The door lock assembly provided in this embodiment can effectively seal the fish-mouth opening 11, preventing dust from the door cavity area from entering the fish-mouth opening 11 after prolonged use, thus preventing severe dust accumulation at the fish-mouth opening 11 or the dust accumulation area of ​​the door, thereby improving the user experience.

[0034] like Figure 1 and Figure 2 As shown, the door lock assembly also includes a sealing component 2, which is disposed on the outer wall surface of the lock body 1 and, in the installed state, as shown... Figure 3 As shown, the sealing component 2 is sandwiched between the lock body 1 and the door sheet metal 3 to provide a seal.

[0035] The sealing assembly 2 includes a main seal 21 and a sealing portion 22. The main seal 21 is partially disposed on the first wall portion 12 and partially disposed on the second wall portion 13. The main seal 21 can cover the area above the fish mouth opening 11, such as... Figure 1 and Figure 2As shown, the main seal 21 includes a first sealing section 211 and a second sealing section 212 connected to each other. The first sealing section 211 is located on the first wall portion 12 and covers the upper area of ​​the side of the fish mouth opening 11 facing the first wall portion 12. The second sealing section 212 is located on the second wall portion 13 and covers the upper area of ​​the side of the fish mouth opening 11 facing the second wall portion 13. In the installed state, the main seal 21 is sandwiched between the first wall portion 12 of the lock body 1 and the door sheet metal 3, achieving a seal from the upper area of ​​the fish mouth opening 11. This prevents water or dust from the vehicle window from falling into the gap between the lock body 1 and the door sheet metal 3, thereby preventing water or dust from entering the fish mouth opening 11 or even the dust accumulation area of ​​the door.

[0036] In this embodiment, there are no restrictions on the structure, length, height, or other positions of the first sealing section 211 and the second sealing section 212; they can be set according to actual conditions. To ensure a sealing effect, the end of the first sealing section 211 away from the second sealing section 212 can extend to the edge of the first wall portion 12 away from the second wall portion 13, or even protrude from the edge of the first wall portion 12 away from the second wall portion 13, to ensure a waterproof and dustproof effect above the fish mouth opening 11.

[0037] A sealing part 22 is disposed on the second wall portion 13 of the lock body 1. One side of the sealing part 22 is disposed along the bottom edge 111 of the fish mouth opening 11, and the other side of the sealing part 22 is fitted with the second sealing section 212 of the lock body 1, so that the second sealing section 212 of the main seal 21 and the sealing part 22 can form a sealing area between the second wall portion 13 of the lock body 1. The fish mouth opening 11 is located within this sealing area. In this way, dust in the door cavity area can be effectively isolated. Figure 1 and Figure 2 The path indicated by the middle arrow leads into the fish mouth opening 11, thereby avoiding dust accumulation inside the fish mouth opening 11 and the dust accumulation area of ​​the car door, thus improving the user experience.

[0038] In other words, this sealing component 2 can prevent water or dust from the vehicle doors and windows from reaching the fish mouth opening 11 through the main seal 21, and can also isolate the door cavity area from the fish mouth opening 11 through the fit between the main seal 21 and the sealing part 22, preventing dust in the door cavity area from entering the fish mouth opening 11. Furthermore, since the sealing part 22 does not independently seal the fish mouth opening 11, but combines with the function of the main seal 21 to achieve the seal at the fish mouth opening 11, compared to a solution that sets the main seal 21 separately and achieves the seal at the fish mouth opening 11 solely through the sealing part 22, it simplifies the overall structure and reduces costs.

[0039] The main seal 21 needs to achieve waterproof and dustproof effects, and its compression in the installed state is required to be relatively large. It has relatively high universality for different car models. The sealing part 22 is mainly used to fill the dust at the edge of the fish mouth 11, preventing dust from entering the dust accumulation area of ​​the door, while preventing large gaps from forming between the lock body 1 and the door sheet metal 3, which would affect the user experience. Therefore, the compression of the sealing part 22 in the installed state is relatively small. Different sealing parts 22 may be required for different car models. Since both the main seal 21 and the sealing part 22 are sandwiched between the lock body 1 shell and the door sheet metal 3, the universality of the main seal 21 is higher than that of the sealing part 22.

[0040] The main seal 21 can be set as a standard part, and some models can share the same main seal 21. The sealing part 22 can be selected according to the specific needs of different models. Therefore, the main seal 21 and the sealing part 22 are two independent sealing parts. Compared with the solution of setting the main seal 21 and the sealing part 22 as an integrated structure, the selection flexibility of the sealing component 2 can be improved, and the cost of the sealing component 2 can be effectively reduced.

[0041] The thickness of the main seal 21 is preferably greater than the thickness of the sealing part 22. This arrangement allows the main seal 21 to compress more when both the main seal 21 and the sealing part 22 are sandwiched between the lock body 1 and the door sheet metal 3 in the installed state, ensuring waterproof and dustproof effects, while the sealing part 22 can ensure its dustproof and filling effects.

[0042] The portion of the fish mouth 11 facing the second wall portion 13 includes a bottom edge 111, a top edge 112, and a side edge 113 connecting the top edge 112 and the bottom edge 111, such as... Figure 1 and Figure 2 As shown, the sealing part 22 includes a first sealing element 221 and a second sealing element 222. The first sealing element 221 is disposed along the bottom edge 111 of the fish mouth opening 11, and the sealing part 22 extends along the side edge 113 of the fish mouth opening 11. Alternatively, only the first sealing element 221 can be disposed along the bottom edge 111, and the second sealing element 222 can extend directly to one side of the main seal 21 and fit against the main seal 21. When the second sealing element 222 extends along the side edge 113, it can improve the coverage of the sealing part 22 on the circumferential edge of the fish mouth opening 11. Furthermore, the first sealing element 221 and the second sealing element 222 can also seal the gap between the lock body 1 and the door sheet metal 3 at the edge of the fish mouth opening 11, avoiding the situation where the large gap between the lock body 1 and the door sheet metal 3 affects the user experience during installation.

[0043] Since the bottom edge 111 and side edge 113 of the fish mouth 11 are easily visible under normal use, the user experience can be improved by sealing the bottom edge 111 and side edge 113 with the first seal 221 and the second seal 222 respectively.

[0044] Of course, in this embodiment, the sealing part 22 can also be provided with a top seal. The top seal extends along the top edge 112 of the fish mouth 11. The gap at the top edge 112 is not easily noticed by the user under normal circumstances. Therefore, the absence of a corresponding seal at the top edge 112 of the fish mouth 11 does not affect the user experience. At the same time, due to the arrangement of the main seal 21 and the sealing part 22, the dustproof requirements at the door lock assembly can be met. Therefore, the second seal 222 directly contacts the second sealing section 212 of the main seal 21, which simplifies the overall structure of the sealing assembly 2.

[0045] like Figure 1 and Figure 2 As shown, the height of the end of the second seal 222 away from the first seal 221 is not lower than the height of the top edge 112 of the fish mouth 11. With this configuration, the second seal 222 can completely cover the side edge 113 of the fish mouth 11. The top of the second seal 222 can extend beyond the top of the fish mouth 11, or the top of the second seal 222 can be aligned with the top edge 112 of the fish mouth 11. This ensures the blocking effect of the second seal 222 along the side edge 113 of the fish mouth 11 between the lock body 1 and the door sheet metal 3, and improves the user experience.

[0046] like Figure 1 and Figure 2 As shown, the sealing part 22 also includes a third sealing member 223, which is connected to the end of the second sealing member 222 away from the first sealing member 221, and the end of the third sealing member 223 away from the second sealing member 222 is in contact with the second sealing section 212. At this time, the first sealing member 221, the second sealing member 222 and the third sealing member 223 of the sealing part 22 are arranged in a roughly Z-shaped structure.

[0047] Of course, in this embodiment, the second seal 222 can also extend directly to the second sealing section 212, and the provision of the third seal 223 makes the arrangement of the second seal 222 and the second sealing section 212 more flexible. Furthermore, it can be adapted to the structure of the main seal 21 of the door lock assembly in the prior art, exhibiting good adaptability, and can also reduce the overall length of the sealing part 22, thereby reducing costs.

[0048] The contact length W between the main seal 21 and the sealing part 22 shall not be less than 2mm, such as Figure 2As shown, the end of the sealing part 22 is attached to the side of the main seal 21. Along the extension direction of the main seal 21, the contact length W between the sealing part 22 and the main seal 21 is not less than 2mm. Alternatively, the end of the main seal 21 can be attached to the side of the sealing part 22. Along the extension direction of the sealing part 22, the contact length W between the sealing part and the sealing part 22 is not less than 2mm.

[0049] The specific bonding length W can be set according to the actual situation, such as 2mm, 3mm, 5mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm, etc. Compared with setting the bonding length to less than 2mm, such as 1mm, 1.5mm, this ensures the sealing between the main seal 21 and the sealing part 22 after bonding, thereby ensuring the dustproof effect.

[0050] In this embodiment, the cross-sectional shape of the two sealing parts is not limited. Preferably, the width of the main seal 21 is greater than its height, and the width of the sealing part 22 is greater than its height, so as to ensure structural stability when subjected to compressive force during installation, thereby ensuring sealing stability in the installed state.

[0051] In this embodiment, the materials of the two sealing parts are not limited, but sealing sponge is preferred due to its good sealing and facilitating properties. Of course, rubber sealing strips or other similar materials can also be used for the sealing parts.

[0052] The distance between the first seal 221 and the bottom edge 111 of the fish mouth 11 is defined as the first distance H1, which is in the range of 0.5mm-4mm. The distance between the second seal 222 and the side edge 113 of the fish mouth 11 is defined as the second distance H2, which is also in the range of 0.5mm-4mm. The first distance H1 and the second distance H2 can be the same or different, and can be set according to the actual situation. No specific restrictions are imposed here.

[0053] Taking the first gap H1 as an example, the first gap H1 can be 0.5mm, 1mm, 2mm, 3mm, 4mm, etc. Of course, the first gap H1 can also be less than 0.5mm or greater than 4mm. When the first gap H1 is set in the range of 0.5mm-4mm, compared with the solution of setting the first gap H1 too large, such as 5mm, the gap between the first seal 221 and the bottom edge 111 of the fish mouth 11 can be reduced as much as possible, ensuring the filling effect of the first seal 221 at the bottom edge 111, avoiding excessive leakage of the gap, improving the user experience, and also effectively ensuring the sealing performance at this point. Furthermore, compared to setting the first gap H1 too small, such as 0.5mm, this solution avoids the situation where the top of the first seal 221 protrudes beyond the bottom edge 111 of the fish mouth 11 due to design errors, assembly errors, etc. It also avoids the situation where the top of the first seal 221 protrudes beyond the bottom edge 111 of the fish mouth 11 due to compression during installation, thus ensuring user experience and preventing interference with the movement of the latch.
