Description

Technical Field

[0001] This invention relates to the field of automotive technology, specifically to a side door lock for an automobile 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. Currently, most vehicles are used for daily commuting, travel, and off-roading. These scenarios do not have high requirements for the waterproof sealing of door locks and the entire vehicle; meeting rain protection requirements is sufficient. Current waterproof solutions for car door locks mainly focus on preventing water from entering the door locks during rain. An important implementation method is to add a baffle plate to the outside of the lock body, so that the water flow entering the car door from the external water cutter or handle is diverted by the baffle plate, preventing water from dripping onto the door lock. However, this solution can only block water from entering the car door from the glass or handle when it rains. If a large amount of water enters the car door and submerges the lock body, it will not be waterproof. Water will enter the lock body, posing a significant risk of causing the door lock motor to fail, thus causing the door lock to malfunction. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a car side door lock and a car, which can still work normally even if the inside of the side door is flooded with water.

[0005] 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 car side door lock, including a housing, a cover plate fixedly connected to the housing, a motor fixing member fixed between the housing and the cover plate, the motor fixing member having at least one first fixing plate group, the cover plate having a second fixing plate group corresponding to the first fixing plate group, the housing, the cover plate and the motor fixing member being fixed together, the corresponding first fixing plate group and the second fixing plate group forming a motor receiving cavity, a motor being fixed inside the motor receiving cavity, a sealing member being provided between the first fixing plate group and the second fixing plate group, the sealing member including a first sealing part disposed between the first fixing plate group and the second fixing plate group, a second sealing part being provided at one end of the first sealing part, the output shaft of the motor passing through the second sealing part, the second sealing part being sealed and slidably connected to the output shaft of the motor.

[0006] Optionally, the first fixing plate group consists of multiple first fixing plates, which together form a cavity that matches the motor. Correspondingly, the second fixing plate group consists of multiple second fixing plates. In the corresponding first fixing plate group and second fixing plate group, the multiple first fixing plates of the first fixing plate group correspond one-to-one with the multiple second fixing plates of the second fixing plate group.

[0007] Optionally, in the first fixing plate assembly, the first fixing plate through which the motor output shaft passes is provided with a first groove for accommodating the second sealing part, and in the second fixing plate assembly, the second fixing plate through which the motor output shaft passes is provided with a second groove for accommodating the second sealing part. After the corresponding first fixing plate and second fixing plate are engaged, the first groove and the second groove form a receiving cavity for accommodating the second sealing part.

[0008] Optionally, the bottom surface of the first sealing part is provided with a first protrusion, and correspondingly, the end face of the first fixing plate group for cooperating with the second fixing plate group is provided with a first sealing groove that matches the first protrusion, and the first protrusion is embedded in the first sealing groove.

[0009] Optionally, the first protrusion is a semi-circular arc protrusion, and correspondingly, the first sealing groove is a semi-circular arc groove.

[0010] Optionally, the top surface of the first sealing part is provided with a second protrusion, and correspondingly, the end face of the second fixing plate assembly for cooperating with the first fixing plate assembly is provided with a second sealing groove that matches the second protrusion, and the second protrusion is embedded in the second sealing groove.

[0013] Optionally, lubricating grease is applied between the hole surface and the motor output shaft.

[0014] Secondly, embodiments of the present invention provide a car equipped with the car side door lock described in the first aspect.

[0015] The beneficial effects of this invention are as follows: The motor door lock of the present invention has a first sealing part provided between the first fixing plate assembly and the second fixing plate assembly to seal the mating ends of the first fixing plate assembly and the second fixing plate assembly. At the same time, a second sealing part is provided at the end of the first sealing part, and the output shaft of the motor passes through the second sealing part. The second sealing part can seal the motor output shaft with the first fixing plate assembly and the second fixing plate assembly, so that the motor can be located in a completely closed motor housing cavity, thereby improving the waterproof sealing effect of the entire door lock.

Detailed Implementation

[0018] Example 1 This embodiment provides a car side door lock, such as Figures 1-2 As shown, it includes a housing 1, a motor fixing component 2, and a cover plate 3. The housing 1 is fixedly connected to the cover plate 3 through multiple fixing holes. The motor fixing component 2 is disposed in the cavity formed between the housing 1 and the cover plate 3. The motor fixing component 2 is fixedly connected to the housing 1 and the cover plate 3 through multiple fixing holes.

[0019] The structure and fixing connection method of the motor fixing component 2, the cover plate 3 and the housing 1 can be achieved using existing technology, and will not be described in detail here.

[0020] like Figures 3-4 As shown, the motor fixing component 2 is provided with at least one set of first fixing plates, and the inner side of the cover plate 3 is provided with multiple sets of second fixing plates. The first fixing plates and the second fixing plates correspond one to one. After the housing 1, the cover plate 3 and the motor fixing component 2 are fixed, the first fixing plates and the corresponding second fixing plates cooperate to form a motor receiving cavity for accommodating the motor 4. The motor 4 is fixed inside the motor receiving cavity.

[0021] In this embodiment, the motor fixing component 2 is provided with three sets of first fixing plates, correspondingly, as follows: Figure 5 As shown, the inner side of the cover plate 3 is provided with three sets of second fixing plates.

[0022] The first fixing plate group is formed by four first fixing plates 5, and the second fixing plate group is formed by four second fixing plates 6. The four first fixing plates 5 of the first fixing plate group and the four second fixing plates 6 of the second fixing plate group correspond one-to-one.

[0023] After the corresponding first fixing plate 5 and second fixing plate 6 are assembled, a motor housing cavity is formed.

[0024] The above structure can be adopted from the current automotive side door lock structure. This embodiment is an improvement on the current automotive side door lock.

[0025] like Figure 6 As shown, a sealing element is provided between the first fixed plate group and the second fixed plate group. The sealing element is a rubber sealing element and is located between the mating ends of the first fixed plate group and the second fixed plate group.

[0026] It is understood that seals can also be made of silicone or closed-cell foam, etc. Those skilled in the art can choose according to actual needs, and will not be described in detail here.

[0027] Specifically, the sealing element includes a first sealing part 7 and a second sealing part 8 disposed on one side of the first sealing part 7. The first sealing part 7 adopts an annular structure and is formed by four sealing strips integrally connected and enclosed. Each sealing strip is disposed between a pair of corresponding first fixing plates 5 and second fixing plates 6 to seal the mating ends of the first fixing plates 5 and the second fixing plates 6.

[0028] One end of the first sealing part 7 is provided with a second sealing part 8. The second sealing part 8 and the first sealing part 7 are integrally injection molded, and the output shaft of the motor 4 passes through the second sealing part 8.

[0029] Specifically: For a set of first and second fixing plates, the first fixing plate 5 through which the output shaft of the motor 4 passes has a first groove at its mating end for cooperating with the second fixing plate 6, and the second fixing plate 6 through which the output shaft of the motor 4 passes has a second groove at its mating end for cooperating with the first fixing plate 5. After the first fixing plate 5 and the second fixing plate 6 are mated, the first groove and the second groove form a cavity for accommodating the second sealing part 8. The output shaft of the motor 4 passes through the second sealing part 8 and is slidably connected to the second sealing part 8. The second sealing part 8 seals the output shaft of the motor 4 with the first fixing plate 5 and the second fixing plate 6.

[0030] The second sealing part 8 is provided with a through hole. The diameter of the through hole is smaller than the diameter of the output shaft of the motor 4. After the output shaft of the motor 4 passes through the second sealing part 8 through the through hole, the output shaft of the motor 4 is interference-fitted with the through hole, so that the second sealing part 8 seals the output shaft of the motor 4. The output shaft of the motor 4 is slidably connected with the hole surface of the through hole, and the second sealing part 8 will not affect the normal operation of the motor.

[0031] Furthermore, in order to enable the output shaft of motor 4 to rotate smoothly, lubricating grease is applied between the output shaft of motor 4 and the surface of the through hole to reduce the friction between the output shaft of motor 4 and the surface of the through hole.

[0032] The bottom surface of each of the four sealing strips of the first sealing part 7 is provided with a strip-shaped first protrusion. Correspondingly, the mating end face of the first fixing plate 5, which is used to cooperate with the second fixing plate 6, is provided with a strip-shaped first sealing groove that matches the first protrusion. After the first sealing part 7 is engaged with the first fixing plate assembly, the first protrusion is embedded in the corresponding first sealing groove, and waterproof adhesive is provided between the bottom surface of the sealing strip and the mating end face of the first fixing plate 5 to bond and fix the sealing strip to the mating end face of the first fixing plate 5.

[0033] Preferably, the first protrusion is an arc-shaped protrusion, and correspondingly, the first sealing groove is an arc-shaped sealing groove that matches the first protrusion.

[0034] It is understood that the first protrusion can also be a rectangular protrusion or a conical protrusion, etc., and those skilled in the art can set it according to actual needs. It will not be described in detail here. The shape of the first sealing groove matches the shape of the first protrusion.

[0035] The top surface of each of the four sealing strips of the first sealing part 7 is provided with a strip-shaped second protrusion 9. Correspondingly, the mating end face of the second fixing plate 6 for cooperating with the first fixing plate is provided with a strip-shaped second sealing groove 10 that matches the second protrusion. After the first sealing part 7 is engaged with the second fixing plate assembly, the second protrusion 9 is embedded in the corresponding second sealing groove 10, and waterproof adhesive is provided between the top surface of the sealing strip and the mating end face of the second fixing plate 6 to bond and fix the sealing strip to the mating end face of the second fixing plate 6.

[0036] Preferably, the second protrusion 9 is an arc-shaped protrusion, and correspondingly, the second sealing groove 10 is an arc-shaped sealing groove that matches the second protrusion 9.

[0037] It is understood that the second protrusion 9 can also be a rectangular protrusion or a conical protrusion. Those skilled in the art can set it according to actual needs, which will not be described in detail here. The shape of the second sealing groove matches the shape of the second protrusion.

[0038] The remaining structures in this embodiment can be achieved using existing technology for automotive side door locks, and will not be described in detail here.

[0039] In this embodiment of the car side door lock, a first sealing part 7 is provided between the first fixing plate assembly and the second fixing plate assembly to seal the mating ends of the first fixing plate assembly and the second fixing plate assembly. At the same time, a second sealing part 8 is provided at the end of the first sealing part 7. The output shaft of the motor 4 passes through the second sealing part 8. The second sealing part 8 can seal the output shaft of the motor 4 with the first fixing plate assembly and the second fixing plate assembly, so that the motor 4 can be located in a completely closed motor housing cavity. The dimension of achieving the waterproof sealing effect has changed from blocking water flow into the interior of the car side door lock to preventing water flow into the interior of the motor housing cavity, thereby improving the waterproof sealing effect of the entire door lock. Even if the door lock is submerged in water, due to the sealing effect of the first sealing part 7 and the second sealing part 8, water will not enter the motor housing cavity, the motor 4 can work normally, avoid motor failure, and meet the usage requirements of the car.

[0040] Meanwhile, the first and second sealing grooves are integrally injection molded along with the motor fixing parts and the cover plate, without increasing the number of parts of the motor fixing parts 2 and the cover plate 3. Compared with the existing side door lock, only the sealing parts consisting of the first sealing part 7 and the second sealing part 8 are added. The modification is simple, the cost is low, and it does not affect the size of the door lock body or the installation boundary.

[0041] Example 2 This embodiment provides a car, which is a car with a side door lock as described in Embodiment 1. The rest of the car's structure can be constructed using existing technology and will not be described in detail here.

[0042] 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.
