DETAILED DESCRIPTION
[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.
[0027] Reference Figures 1 to 3 As shown, it shows an embodiment of the connection mechanism and the vehicle door of the utility model. The connection mechanism includes a lifting assembly 100 and a connection assembly 200. The lifting assembly 100 is used to drive the glass 300 to perform lifting movement; the connection assembly 200 includes a clamping member 210, a connecting guide rail 220 and a sliding member 230. One end of the clamping member 210 is connected to the glass 300, and the other end is connected to the sliding member 230. The sliding member 230 is slidably connected to the connecting guide rail 220, and the connecting guide rail 220 is fixed to the vehicle door sheet metal 400. The lifting assembly 100 is started to drive the glass 300 to perform lifting movement, thereby driving the sliding member 230 to slide on the connecting guide rail 220.
[0028] Specifically, the connecting mechanism includes a lifting assembly 100, which is used to drive the glass 300 to perform lifting movements. The lifting assembly 100 includes a motor 110, a pull rope, a lifting guide rail 120 and a glass clamping block 130. Under normal working conditions, the lifting button is touched, the motor 110 is started, and the motor 110 pulls the pull rope to make the glass clamping block 130 perform lifting movements on the lifting guide rail 120, thereby realizing the lifting movement of the glass 300 on the car door.
[0029] The connection mechanism also includes a connection component 200, which is used to connect the glass 300 and the door sheet metal 400 so that the glass 300 and the door sheet metal 400 generate a Y-direction constraint relationship (the Y-direction refers to the Y-direction of the vehicle body coordinate); the connection component 200 is arranged on one side of the lifting component 100 and is spaced apart from the lifting component 100; the connection component 200 includes a clamping member 210, a connecting guide rail 220 and a sliding member 230, the clamping member 210 is used to clamp the glass 300, one end of the clamping member 210 is fixedly connected to the glass 300, and the other end is connected to the sliding member 230; the sliding member 230 is slidably connected to the connecting guide rail 220, and the connecting guide rail 220 is fixed on the door sheet metal 400, so that the glass 300 is connected to the door sheet metal 400 through the connection component 200 to further limit the shaking amount of the glass 300 in the Y direction.
[0030] When the lifting assembly 100 is started, the lifting assembly 100 drives the glass 300 to perform lifting motion, and at this time, the glass 300 drives the clamping member 210 to perform lifting motion, and the clamping member 210 drives the sliding member 230 to perform lifting motion along the connecting guide rail 220 .
[0031] For example, when the glass 300 rises to the top dead center, the sliding member 230 is also located at the highest position of the connecting guide rail 220. At this time, when the door is opened or closed, when the limiter is over-shifted, the limiter slider forms an impact in the limiter arm shift slot, and the impact force is transmitted to the glass 300 through the door sheet metal 400, thereby causing the glass 300 to vibrate. The amplitude of the corner point at the top of the side of the glass 300 close to the connection between the door and the body is the largest relative to the amplitude of the entire glass 300, so the glass 300 It has Y-direction vibration. At this time, the glass clamping block 130 and the lifting guide rail 120 of the lifting assembly 100 have connection constraints on the glass 300. At the same time, the connecting assembly 200 also has connection constraints on the glass 300. Under the constraints of the lifting assembly 100 and the connecting assembly 200, the amplitude of the glass 300 is greatly weakened, and the Y-direction shaking amount of the glass 300 is greatly reduced, which can significantly weaken or eliminate the vibration of the glass 300, thereby increasing the grade of the car door and improving the user experience.
[0032] In particular, the lifting assemblies 100 in this embodiment are provided with two groups, and are spaced apart in the middle below the glass 300; the connecting assemblies 200 are provided with one group, and the connecting assemblies 200 are spaced apart on one side of the lifting assemblies 100, and are arranged adjacent to one of the lifting assemblies 100; because when the door is opened or closed, the vibration amplitude of the top corner of the glass 300 away from the open side of the door (that is, the side of the glass 300 close to the connection between the door and the car body) is the largest relative to the vibration amplitude of the entire glass 300 area, the connecting assemblies 200 are mainly arranged on the side close to the connection between the door and the car body, so as to better limit the Y-direction vibration amplitude of the glass 300, avoid the problem of large Y-direction shaking of the glass 300 and produce abnormal noise, thereby improving user experience.
[0033] In the present application, the connecting component 200 is added to the lifting component 100, so that the glass 300, the connecting component 200 and the door sheet metal 400 form an integral connection structure. During the lifting and lowering process of the glass 300, the glass 300 drives the clamping member 210 to pull the sliding member 230 to move up and down in the connecting guide rail 220, so that the glass 300 and the door sheet metal 400 have a Y-direction constraint relationship. Therefore, during the process of opening or closing the door, the lifting component 100 and the connecting component 200 both have a constraint effect on the Y-direction vibration of the glass 300, which can greatly reduce the Y-direction shaking amount of the glass 300, and significantly reduce or eliminate the vibration of the glass 300, thereby increasing the grade of the door and improving the user experience. At the same time, the connecting component 200 has a simple structure and low production cost.
[0034] In one embodiment, referring to Figures 1 to 3As shown, the sliding member 230 includes a roller 231 and a bracket 232. The roller 231 is slidably connected to the connecting guide rail 220. One side of the bracket 232 is fixedly connected to the roller 231, and the other side is connected to the clamping member 210. Specifically, the sliding member 230 is used to connect the connecting guide rail 220 and the clamping member 210, and the sliding member 230 can slide in the connecting guide rail 220. The extension direction of the connecting guide rail 220 is consistent with the extension direction of the lifting guide rail 120 in the lifting assembly 100, that is, it extends from the end close to the glass 300 to the direction away from the glass 300, so as to ensure the sliding of the sliding member 230. The sliding member 230 includes a roller 231 and a bracket 232. The roller 231 facilitates the sliding of the sliding member 230 in the connecting guide rail 220. The bracket 232 is convenient for the sliding of the sliding member 230 with the connecting guide rail 220. The roller 231 is fixedly mounted on one side of the bracket 232, and the other side of the bracket 232 is connected to the clamp 210, so that the roller 231 and the clamp 210 are located on both sides of the bracket 232, and the clamp 210 is fixedly connected to the glass 300. When the glass 300 is lifted, the clamp 210 is subjected to the force to follow the glass 300 to do the lifting movement, thereby driving the bracket 232 and the roller 231 to do the lifting movement along the direction of the connecting guide rail 220, thereby ensuring that the connecting assembly 200 and the lifting assembly 100 operate synchronously. The sliding member 230 has a simple structure and low production cost. At the same time, the sliding member 230 can easily slide on the guide rail to avoid the sliding member 230 from getting stuck when sliding.
[0035] In a specific embodiment, refer to Figure 3As shown, the connecting guide rail 220 includes two side walls 221 that are relatively spaced apart, the roller 231 is disposed between the two side walls 221, and the radial direction of the roller 231 is limited by the two side walls 221. Specifically, the connecting guide rail 220 includes an opening, the opening faces the direction of the lifting guide rail 120, that is, toward the side of the door away from the connection with the vehicle body, and the two sides of the opening have two side walls 221 that are relatively spaced apart, and the two side walls 221 refer to the two side walls 221 disposed at the opening facing the inside and outside of the vehicle respectively; one end of the sliding member 230 is slidably connected to the two side walls of the opening, that is, the roller 231 slides in the opening, the roller 231 is disposed between the two side walls 221, and the radial direction of the roller 231 is limited by the two side walls 221; The other end of the sliding member 230 extends through the opening toward the direction close to the lifting guide rail 120, that is, the bracket 232 is arranged on the side of the opening close to the lifting guide rail 120. Therefore, the radial direction of the roller 231 is blocked by the two side walls of the opening, thereby limiting the movement of the roller 231 toward the inside or outside of the vehicle, further restraining the vibration of the connecting component 200 on the glass 300, greatly reducing the shaking amount of the glass 300, weakening the vibration generated by the glass 300, improving the grade of the car door, and thus improving the user experience.
[0036] In a specific embodiment, refer to Figure 3 As shown, the bracket 232 includes a groove 2321 , and the groove 2321 is formed by the bracket 232 being recessed inwardly on one side relative to the roller 231 ; one end of the clamping member 210 is located in the groove 2321 and connected to the bracket 232 . Specifically, one side of the bracket 232 is connected to the roller 231, and the other side is connected to the clamping member 210, and the roller 231 and the clamping member 210 are arranged opposite to each other; a groove 2321 is provided on the bracket 232, and the groove 2321 is formed by the other side of the bracket 232 being recessed toward one side of the bracket 232, that is, the groove 2321 is recessed by the side of the bracket 232 away from the roller 231 toward the direction close to the roller 231, and the groove 2321 is used to accommodate one end of the clamping member 210, so that one end of the clamping member 210 is located in the groove 2321 and connected to the bracket 232, thereby improving the integration of the connecting component 200 and reducing the occupied space of the connecting component 200; at the same time, the connection between the bracket 232 and the clamping member 210 is protected, so that the clamping member 210 and the bracket 232 are not easily disconnected, thereby improving the structural stability and service life of the connecting component 200.
[0037] In particular, the bracket 232 in this embodiment is made of DC01 material, and the thickness of the bracket 232 is set to 3.5mm-5.0mm. Specifically, the DC01 material is a cold-formed steel with high strength, hardness and fatigue resistance, as well as good plasticity and toughness. Therefore, the bracket 232 has high strength, hardness, plasticity and other properties, is easy to manufacture, and improves the service life and structural stability of the bracket 232; at the same time, the thickness of the bracket 232 is set to 3.5mm-5.0mm to ensure the strength of the bracket 232 and further improve the service life of the bracket 232. The bracket 232 in this embodiment adopts a thickness of 4.0mm.
[0038] In one embodiment, referring to Figure 3 As shown, the sliding member 230 further includes a metal bushing 233, which passes through one end of the clamping member 210 located in the groove 2321 from one side of the bracket 232 to the other side of the bracket 232, so as to rivet the bracket 232 and the clamping member 210. Specifically, the sliding member 230 further includes a metal bushing 233, and two through holes are provided on the bracket 232 along a concave direction perpendicular to the groove 2321, and the two through holes pass through both sides of the bracket 232, and the two through holes are correspondingly provided on both sides of the groove 2321; one end of the clamping member 210 is provided with a through hole, and the through hole passes through both sides of the clamping member 210; one end of the metal bushing 233 passes through the two through holes and the through hole from one side of the bracket 232 to the other side of the bracket 232 One side, so that the bracket 232 and the clamp 210 are riveted, and the clamp 210 is slidably connected with the metal bushing 233; therefore, the metal bushing 233 passes through the bracket 232 and one end of the clamp 210 from one side of the bracket 232 to the other side of the bracket 232, so as to connect the end of the clamp 210 located in the groove 2321 with the bracket 232, so that the connection method between the bracket 232 and the clamp 210 is simple, the installation and disassembly are simple and fast, and the cost is low.
[0039] Since the glass 300 is installed on a vehicle door, especially a frameless vehicle door, the glass 300 needs to be adjusted to a suitable position according to the size of the vehicle body, so the clamp 210 is slidably connected with the metal bushing 233, so that the clamp 210 can slide along the axial direction of the metal bushing 233, and then the distance between the glass 300 clamped by the clamp 210 and the vehicle door can be adjusted, that is, the clamp 210 is axially slid along the metal bushing 233, so that the glass 300 can be moved toward the inside or outside of the vehicle, and then the distance between the glass 300 and the vehicle door can be adjusted, so that the position adjustment method of the glass 300 is simple, fast and low in cost. In particular, the clamp 210 is tightly connected with the metal bushing 233, so when the clamp 210 slides along the axial direction of the metal bushing 233, the clamp 210 needs to be screwed by a tool such as a screwdriver.
[0040] In a specific embodiment, a wear-resistant coating (not shown in the figure) is provided at the connection area between the clamp 210 and the metal bushing 233. Specifically, the metal bushing 233 connects the bracket 232 and the clamp 210 in the form of rivets, so the clamp 210 is provided with the through hole to facilitate the passage of the metal bushing 233, and the through hole is tightly fitted with the metal bushing 233, that is, the surface area of the through hole is the connection area between the clamp 210 and the metal bushing 233, and the clamp 210 and the metal bushing 233 are in sliding connection, so when the clamp 210 slides on the metal bushing 233, friction will be generated at the connection between the clamp 210 and the metal bushing 233. In order to increase the service life of the clamp 210 and the metal bushing 233, a wear-resistant coating is provided at the connection area between the clamp 210 and the metal bushing 233. A wear-resistant coating is provided on the domain, and the wear-resistant coating can also be arranged on the outer surface of the metal bushing 233. Therefore, the position of the wear-resistant coating in this embodiment is not limited, but the outer surface area of the metal bushing 233 is larger than the area of the connection area between the clamp 210 and the metal bushing 233. Therefore, the wear-resistant coating is arranged on the connection area between the clamp 210 and the metal bushing 233, which can reduce the cost; at the same time, grease is also added to the connection area between the clamp 210 and the metal bushing 233 to prevent the clamp 210 and the metal bushing 233 from generating abnormal noise due to the friction force, further preventing the problem of abnormal noise in the car door, improving the grade of the car door, and improving the user experience.
[0041] In one embodiment, there is a gap (not shown in the figure) between the roller 231 and the connecting guide rail 220, and the single-side range of the gap is 0.1mm-0.2mm. Specifically, the roller 231 slides in the connecting guide rail 220. Considering the assembly manufacturing tolerance of the roller 231 and the connecting guide rail 220, to ensure that the roller 231 can be assembled into the connecting guide rail 220, a gap is provided between the roller 231 and the connecting guide rail 220, and the single-side range of the gap is 0.1mm-0.2mm. The single side of the gap refers to the vertical distance from the edge of the roller 231 along the radial direction of the roller 231 to the nearest end of the connecting guide rail 220. The single side of the gap used in this embodiment is 0.1mm. Therefore, the gap in this embodiment makes it easier for the roller 231 to be installed in the connecting guide rail 220, thereby improving the assembly efficiency. Meanwhile, grease is applied between the roller 231 and the connecting guide rail 220 to prevent the roller 231 from making abnormal noise when the connecting guide rail 220 slides.
[0042] In a specific embodiment, the clamping piece 210 is made of PA6 and GF30 materials. Specifically, PA6, also known as nylon 6, is a translucent or opaque milky white particle with the characteristics of thermoplasticity, light weight, good toughness, chemical resistance and durability. It is generally used in automotive parts, mechanical parts, electronic and electrical products, engineering accessories and other products; GF refers to glass fiber, which is a common inorganic filler for modified plastics; the PA6 and GF30 materials refer to 30% glass fiber reinforced PA6, which has the characteristics of high strength, good heat resistance, good impact resistance, and excellent dimensional stability. Therefore, the clamping piece 210 made of the PA6+GF30 material has high strength, good heat resistance, good impact resistance, and excellent dimensional stability. It has the characteristics of good thermal resistance and impact resistance, that is, excellent dimensional stability, thereby ensuring the clamping effect of the clamping member 210 on the glass 300, and due to its excellent heat resistance, the clamping effect of the clamping member 210 can still be maintained at high temperatures; at the same time, when the clamping member 210 is subjected to the impact force of the car door when opening and closing the door, due to its good impact resistance, the impact force transmitted to the glass 300 is greatly reduced, thereby further reducing the shaking amount of the glass 300, weakening or eliminating the vibration of the glass 300, thereby increasing the grade of the car door and improving the user experience.
[0043] In one embodiment, referring to Figures 1 to 3As shown, the clamping member 210 is fastened to the glass 300 by bolts 240. Specifically, the two sides of the clamping member 210 are clamped on the two sides of the glass 300, and the clamping member 210 and the glass 300 are fixedly connected by the fastening method of the bolts 240, that is, the clamping member 210 and the glass 300 are respectively provided with through holes, one end of the bolt 240 is passed from one side of the clamping member 210 through the through holes of the clamping member 210 and the glass 300 to the other side of the clamping member 210, and the bolt 240 is tightened by a nut, so as to fasten the clamping member 210 and the glass 300. The fastening method of the clamping member 210 and the glass 300 is simple, the assembly and disassembly efficiency is high, and the cost is low.

[0046] In one embodiment, referring to Figures 1 to 3As shown, the door sheet metal 400 includes a fixing portion 410, and the fixing portion 410 is protruded from one side of the door sheet metal 400 toward the interior of the vehicle, and the connecting guide rail 220 is fixedly mounted on the fixing portion 410. Specifically, in order to ensure that the glass 300 and the door sheet metal 400 form a Y-direction constraint relationship, the connecting assembly 200 is disposed on the door sheet metal 400; since the glass 300 is not in the same plane as the door sheet metal 400, the glass 300 is disposed on the side of the door sheet metal 400 facing the interior of the vehicle, and the glass 300 is connected to the clamping member 210, the movement of the glass 300 will drive the clamping member 210 to move and then drive the sliding member 230 to move. In order to ensure the connection stability between the glass 300 and the door sheet metal 400 and to ensure In order to ensure that the lifting and lowering movement of the glass 300 can operate normally, the fixing part 410 is provided on the door sheet metal 400, and the fixing part 410 is used to fix the connecting guide rail 220, and then connect the connecting component 200. The fixing part 410 is raised toward the direction of the vehicle interior, and the connecting guide rail 220 is fixed on the fixing part 410, so that there is a distance between the connecting guide rail 220 and the door sheet metal 400, thereby ensuring the fixed connection between the clamping member 210 and the glass 300, improving the structural stability of the door, and the connection method is simple.
