Description

[Technical Field]

[0001] (Cross-reference of related applications) This application claims priority to the Chinese patent application with patent application number 202210762585.5, filed on June 30, 2022, and titled "Vehicle Door Glass Assembly, Vehicle Door Assembly and Vehicle".

[0002] The present invention relates to the vehicle technology field, and more particularly to vehicle door glass assemblies, vehicle door assemblies, and vehicles. [Background technology]

[0003] Currently, widely used flush vehicle door glass assemblies have guide frames attached to the front and rear ends of the vehicle door glass. The guide frames are locked to a seal strip on the vehicle door sheet metal rail, and the outer surface of the vehicle door glass is flush with the seal strip. That is, the inner surface of the vehicle door glass, the guide frame, and the edge of the vehicle door glass are connected to the seal strip, but the outer surface of the vehicle door glass is not connected to the seal strip. The guide frame and seal strip work together to provide better guidance for the lift slide of the vehicle door glass, and the locking of the guide frame and seal strip during vehicle operation stabilizes the glass, preventing it from shaking due to airflow. However, a jamming phenomenon occurs in the lift slide of the glass, the glass is easily offset in its stretching direction, and there is a problem of wind and water leakage due to wear of the seal strip at one end. [Overview of the project] [Problems that the invention aims to solve]

[0004] The present invention aims to provide a vehicle door glass assembly, a vehicle door assembly, and a vehicle that solve the jamming phenomenon present in the lift slide of current vehicle door glass, the phenomenon in which the glass is easily offset horizontally and wind and water leak due to wear of the seal strip at one end. [Means for solving the problem]

[0005] To solve the above objectives, the present invention provides a vehicle door glass assembly comprising: a vehicle door glass that is sealed to the vehicle door body and slidably fitted along the vertical direction, having first and second ends facing each other in the longitudinal direction, moving along the vertical direction by the drive of the lifting mechanism, with the point of force reception between the lifting mechanism and the vehicle door glass as the main support point; and a weight structure mounted on the vehicle door glass, wherein, while the vehicle door glass is moving along the vertical direction, the weight structure adjusts the center of gravity of the vehicle door glass so that the torque generated with respect to the main support point by the force received by the vehicle door glass is balanced. The present invention further provides a vehicle door assembly comprising the above-mentioned vehicle door glass assembly, the above-mentioned vehicle door body, and the above-mentioned lifting mechanism mounted on the above-mentioned vehicle door body.

[0006] The present invention further provides a vehicle comprising the above-described vehicle door assembly. [Effects of the Invention]

[0007] The vehicle door glass assembly, vehicle door assembly, and vehicle of the present invention are provided with a weight structure on the vehicle door glass, and as the vehicle door glass moves along the vertical direction, the weight structure adjusts the center of gravity of the vehicle door glass so that the torque generated on the main support point between the vertical mechanism and the vehicle door glass due to the force acting on the vehicle door glass is balanced with each other, thereby increasing the stability of the less stable end of the vehicle door glass and preventing the less stable end from tilting toward the more stable end, thereby allowing the vertical mechanism to drive the vehicle door glass and slide smoothly along the vertical direction, eliminating jamming phenomena, and preventing the formation of a gap between the less stable end of the vehicle door glass and the vehicle door body, which would otherwise break the seal between the vehicle door glass and the vehicle door body.

[0008] Below, in order to more clearly explain the technical proposal according to the embodiments of the present invention, the drawings used in the embodiments will be briefly described. However, these are only some embodiments of the present invention, and it will be obvious to those skilled in the art that other drawings can be obtained based on these drawings without requiring any innovative ingenuity.

[0010] The following describes the technical proposals according to embodiments of the present invention more clearly and completely with reference to the drawings of embodiments of the present invention. Of course, the embodiments described below are only a part of the embodiments of the present invention, and the present invention is not limited thereto. Any other embodiments that can be obtained by those skilled in the art without innovative ingenuity based on the embodiments of the present invention should be understood to fall within the scope of the protection of the present invention.

[0011] (Example 1) As shown in FIG. 1, the present invention includes a vehicle door body, and a vehicle door glass 1 that is slidably fitted along the lifting direction Z while being sealed to the vehicle door body, and has a first end 11 and a second end 12 that face each other in the longitudinal direction X. The vehicle door glass 1 is moved in the lifting direction Z by the drive of a lifting mechanism 9, and the force application point between the vehicle door glass 1 and the lifting mechanism 9 is a main support point O. The present invention also includes a weight structure 2 mounted on the vehicle door glass 1. The vehicle door glass 1 adjusts the center of gravity O1 of the vehicle door glass 1 by the weight structure 2 while being moved along the lifting direction Z, so that the torques generated by the forces received by the vehicle door glass 1 with respect to the main support point O are balanced with each other, thereby providing a vehicle door glass assembly.

[0012] The vehicle door glass assembly of the present invention is provided with a weight structure 2 on the vehicle door glass 1. When the vehicle door glass 1 is moved along the lifting direction Z, the weight structure 2 adjusts the center of gravity of the vehicle door glass 1, so that the torques generated by the forces received by the vehicle door glass 1 with respect to the main support point O between the lifting mechanism 9 and the vehicle door glass 1 are balanced with each other. This increases the stability of the end with low stability of the vehicle door glass 1 and prevents the end with low stability of the vehicle door glass 1 from tilting towards the end with good stability. As a result, the lifting mechanism 9 can drive the vehicle door glass 1 to slide smoothly along the lifting direction Z, preventing jamming. It can also avoid the occurrence of a gap between the end with low stability of the vehicle door glass 1 and the vehicle door body, thereby preventing the seal between the vehicle door glass 1 and the vehicle door body from being broken.

[0013] Specifically, the vehicle door glass 1 may be the vehicle door glass 1 of the vehicle front door or the vehicle door glass 1 of the vehicle rear door. Due to the streamlined design of the vehicle body, the vehicle door glass 1 forms an asymmetric structure with respect to its center of gravity, and the stability difference between the first end 11 and the second end 12 of the vehicle door glass 1 becomes large. Therefore, by providing the weight structure 2, the stability of the end with low stability of the vehicle door glass 1 can be enhanced. As shown in FIG. 2, the lifting mechanism 9 is connected to the vehicle door glass 1 by a carriage 91. A carriage hole 15 for mounting the carriage 91 on the vehicle door glass 1 is provided. The center of the carriage hole 15 is the position of the main support point O. The weight structure 2 does not contact the lifting mechanism 9, that is, the weight structure 2 does not provide power for the downward movement of the vehicle door glass 1. Since the specific structure and operating principle of the lifting mechanism 9 are the same as those of the prior art, specific descriptions will be omitted here.

[0014] As shown in FIGS. 1 to 5, in this embodiment, the vehicle door glass 1 is a flush vehicle door glass, that is, the outer surface 17 facing the outside of the vehicle door glass 1 is substantially flush with the outer surface of the vehicle door body, and only the inner surface 16 facing the inside of the vehicle door glass 1 and the edge of the vehicle door glass 1 are slidably fitted while being sealed to the vehicle door body. Desirably, the vehicle door glass 1 is a non-flush vehicle door glass, that is, the inner surface and the outer surface of the vehicle door glass are respectively connected to and sealed to the seal strip on the vehicle door body while being slidably fitted. Compared with the non-flush vehicle door glass, the vehicle door glass 1 according to this embodiment can enhance the aerodynamic and aesthetic characteristics of the vehicle. However, due to the lack of stability during lift-slide and sealing stability, the present invention can enhance the stability during lift-slide and sealing stability of the flush vehicle door glass 1 by providing the weight structure 2.

[0015] In an embodiment of the present invention, the length of the first end 11 of the vehicle door glass 1 extending in the vertical direction Z is shorter than the length of the second end 12 of the vehicle door glass 1 extending in the vertical direction Z, and the center of gravity of the weight structure 2 is located between the main support point O and the first end 11 of the vehicle door glass 1. Since the sealing sliding fitting surface between the second end 12 of the vehicle door glass 1 and the vehicle door body is larger than the sealing sliding fitting surface between the first end 11 of the vehicle door glass 1 and the vehicle door body, the stability of the second end 12 of the vehicle door glass 1 exceeds the stability of the first end 11 of the vehicle door glass 1. The weight structure 2 is provided in close proximity to the first end 11 of the vehicle door glass 1 relative to the second end 12 of the vehicle door glass 1, thereby increasing the stability of the first end 11 of the vehicle door glass 1. Specifically, the vehicle door glass 1 is the vehicle door glass 1 on the front door of the vehicle, the first end 11 of the vehicle door glass 1 is the front end close to the head of the vehicle, and the second end 12 of the vehicle door glass 1 is the rear end close to the tail of the vehicle.

[0016] As shown in Figure 1, a weatherstrip 8 is attached to the vehicle door body, and the vehicle door glass 1 slides and fits through the weatherstrip 8 along the vertical direction Z, sealing against the weatherstrip 8. The weight structure 2 is located below the weatherstrip 8. The weight structure 2 is always in an invisible position on the vehicle door and does not affect the range of lift-slide of the vehicle door glass 1. Specifically, when the vehicle door glass 1 is fully closed, the gap between the weight structure 2 and the weatherstrip 8 is 10 mm or more, and no interference occurs between the weight structure 2 and the weatherstrip 8.

[0017] In an embodiment of the present invention, the torque generated with respect to the main support point O of the force acting on the vehicle door glass 1 satisfies the following relationship:

[0018]

number

[0019] However, M1 is the torque generated relative to the main support point O by the sliding friction force between the first end 11 of the vehicle door glass 1 and the vehicle door body, M2 is the torque generated relative to the main support point O by the sliding friction force between the second end 12 of the vehicle door glass 1 and the vehicle door body, and M3 is the torque generated relative to the main support point O by the sliding friction force between the weatherstrip 8 and the vehicle door body. 車両ドアガラス This is the torque generated by the gravity of the vehicle door glass 1 relative to the main support point O, and M ウェート This is the torque generated by the gravity of the weight structure 2 with respect to the main support point O.

[0020] In the present invention, torque is defined as the vector product of the distance vector from the main support point O to the point of force application and the force vector, with the direction from the main support point O to the first end of the vehicle door glass defined as the positive direction and the direction from the main support point O to the second end of the vehicle door glass defined as the negative direction.

[0021] In this embodiment, since the center O2 of the weatherstrip 8 and the center of gravity O1 of the vehicle door glass 1 are both located between the main support point O and the first end 11 of the vehicle door glass 1, M1, M3, M 車両ドアガラス M ウェート Both are positive numbers, and M2 is a negative number. By placing the center O2 of the weatherstrip 8 and the center of gravity O1 of the vehicle door glass 1 on one side close to the first end 11 of the vehicle door glass 1, which is the main support point O, it is helpful to enhance the stability of the first end 11 of the vehicle door glass 1. Preferably, the center of the weatherstrip is located on one side close to the second end of the vehicle door glass 1 which is the main support point, or in the movement path of the main support point. Preferably, the center of gravity of the vehicle door glass is located on one side close to the second end of the vehicle door glass which is the main support point, or in the movement path of the main support point, and M 車両ドアガラス It is zero. Preferably, the center O2 of the weatherstrip is located between the main support point O and the second end of the vehicle door glass, and M3 is a negative number.

[0022] As shown in FIGS. 1, 3, and 4, the longitudinal direction of the vehicle door glass 1 is the X direction, and the thickness direction of the vehicle door glass 1 is the Y direction. Since the thickness of the vehicle door glass 1 is small, the distance of the force received by the vehicle door glass 1 from the main support point O in the Y direction is close to zero, forming a small torque, which has no impact on the stability of the lift slide and the sealing stability of the vehicle door glass 1 and can be ignored. That is, since there is no offset in the Y direction of the vehicle door glass 1, only the torque generated by the force received by the vehicle door glass 1 in the X direction with respect to the main support point O needs to be considered.

[0023] Specifically, It is 31170 of JPEG0007855734000002.jpg. Here, α is the angle between the vertical bisector of the weather strip 8 and the vertical direction, β is the angle between the lifting direction and the vertical direction, L1 is the distance vector from the main support point O in the X direction to the first end 11 of the vehicle door glass 1, F1 is the sliding friction force between the first end 11 of the vehicle door glass 1 and the vehicle door body, L2 is the distance vector from the main support point O in the X direction to the second end 12 of the vehicle door glass 1, F2 is the sliding friction force between the second end 12 of the vehicle door glass 1 and the vehicle door body, L3 is the distance vector from the main support point O in the X direction to the center O2 of the weather strip 8, F3 is the sliding friction force between the weather strip 8 and the vehicle door glass 1, L 車両ドアガラス is the distance vector from the main support point O in the X direction to the center of gravity O1 of the vehicle door glass 1, M 車両ドアガラス teeth is the weight of the vehicle door glass 1, L ウェート is the distance vector from the main support point O in the X direction to the center of gravity of the weight structure 2, M ウェート is the weight of the weight structure 2.

[0024] In this embodiment, M ウェートThe mass is between 0.1 kg and 2 kg, preferably between 0.3 kg and 1.1 kg. If the mass of the weight structure 2 is too heavy, the impact on the vehicle door glass 1 when opening and closing the vehicle door is too great, and if the weight structure 2 is too light, it cannot perform its role in increasing the stability of the first end 11 of the vehicle door glass 1. Since β is 0 degrees, the torque generated with respect to the main support point in the X direction of the force acting on the vehicle door glass 1 satisfies the following relationship.

[0025]

number

[0026] In other words, the following relationship is obtained.

[0027]

number

[0028] This allows us to determine the mounting position of the weight structure 2.

[0029] As shown in Figure 1, in an embodiment of the present invention, a first seal strip 3 and a second seal strip 4 are mounted on the vehicle door body along the vertical direction Z, the first end 11 of the vehicle door glass 1 is slidably fitted to the vehicle door body while being sealed by the first seal strip 3, and the second end 12 of the vehicle door glass 1 is slidably fitted to the vehicle door body while being sealed by the second seal strip 4. Specifically, as shown in Figures 3 to 5, the outer surface 17 of the vehicle door glass 1 is flush with the first seal strip 3 and the second seal strip 4, the inner surface 16 and edge of the first end 11 of the vehicle door glass 1 are slidably fitted while being sealed by the first seal strip 3, and the inner surface 16 and edge of the second end 12 of the vehicle door glass 1 are slidably fitted while being sealed by the second seal strip 4.

[0030] As shown in Figure 3, at least a first limit structure 5 is provided between the first end 11 of the vehicle door glass 1 and the first seal strip 3. As shown in Figures 4 and 5, at least one second limit structure 6 and at least one third limit structure 7 are provided between the second end 12 of the vehicle door glass 1 and the second seal strip 4. The first limit structure 5 and the second limit structure 6 work together to prevent the vehicle door glass 1 from moving along its thickness direction Y, and the third limit structure 7 prevents the vehicle door glass 1 from moving along its longitudinal direction X. Because the second end 12 of the vehicle door glass 1 extends a long length along the vertical direction Z, and the first end 11 of the vehicle door glass 1 extends a short length along the vertical direction Z, a second limit structure 6 and a third limit structure 7 are provided between the second end 12 of the vehicle door glass 1 and the second seal strip 4. However, by providing only a first limit structure 5 between the first end 11 of the vehicle door glass 1 and the first seal strip 3, the vehicle door glass 1 is reliably limited in the X and Y directions.

[0031] As shown in Figure 3, in an embodiment of the present invention, the first limit structure 5 comprises a first guide frame 51, which is mounted on the first end 11 of the vehicle door glass 1 along the vertical direction Z, and the first seal strip 3 has a first guide groove 52 along the vertical direction, and the first guide groove 52 has two opposing first limit surfaces 53 in the thickness direction Y of the vehicle door glass 1, and the first guide frame 51 slides in the first guide groove 52 in contact with the two first limit surfaces 53. Specifically, in Figure 3, reference numeral 51 indicates a cross-section of the same first guide frame 51. As shown in Figure 2, the two first guide frames 51 are mounted on the inner surface 16 of the first end 11 of the vehicle door glass 1 by a first stand 13. The first seal strip 3 is further provided with a first mounting groove 31 along the vertical direction Z, and the first mounting groove 31 communicates with the first guide groove 52 and is fitted to the first end 11 of the vehicle door glass 1. At least one first lip 32 and at least one second lip 33 are provided in the first mounting groove 31, the first lip 32 is slidably fitted to the inner surface 16 of the first end 11 of the vehicle door glass 1 while being sealed, and the second lip 33 is slidably fitted to the edge of the first end 11 of the vehicle door glass 1 while being sealed.

[0032] As shown in Figures 4 and 5, the second limit structure 6 comprises a second guide frame 61, and the third limit structure 7 comprises a third guide frame 71. The second guide frame 61 and the third guide frame 71 are mounted on the second end 12 of the vehicle door glass 1 at intervals along the vertical direction Z. The second seal strip 4 has a second guide groove 62 along the vertical direction, and two second limit surfaces 63 and two third limit surfaces 73 are provided within the second guide groove 62. The two second limit surfaces 63 are positioned opposite each other in the thickness direction Y of the vehicle door glass 1, and the two third limit surfaces 73 are positioned opposite each other in the longitudinal direction X of the vehicle door glass 1. The second guide frame 61 is in contact with the two second limit surfaces 63 and is slidable in the second guide groove 62, and the third guide frame 71 is in contact with the two third limit surfaces 73 and is slidable within the second guide groove 62.

[0033] Specifically, in Figure 4, reference numeral 61 indicates a cross-section of the same second guide frame 61. In Figure 5, reference numeral 71 indicates a cross-section of the same third guide frame 71. As shown in Figure 2, the three second guide frames 61 and the two third guide frames 71 are mounted on the inner surface 16 of the second end 12 of the vehicle door glass 1 by the second stand 14. The two third guide frames 71 are provided close to the upper and lower ends of the vehicle door glass 1, and the three second guide frames 61 are provided spaced apart between the two third guide frames 71. The second seal strip 4 is further provided with a second mounting groove 41 along the vertical direction Z, and the second mounting groove 41 is in communication with the second guide groove 62 and the third guide groove 72, and fits together with the second end 12 of the vehicle door glass 1. The second mounting groove 41 is provided with at least one third lip 42 and at least one fourth lip 43. The third lip 42 is slidably fitted to the inner surface 16 of the second end 12 of the vehicle door glass 1 while being sealed, and the fourth lip 43 is slidably fitted to the edge of the second end 12 of the vehicle door glass 1 while being sealed.

[0034] As shown in Figures 2 and 7, in this embodiment and the second embodiment, the two first guide frames 51 and the first stand 13 are integrally constructed. The three second guide frames 61, the two third guide frames 71 and the second stand 14 are integrally constructed. As shown in Figure 9, in the third embodiment, the first guide frame 51 is directly fixed to the inner surface 16 of the first end 11 of the vehicle door glass 1. The second guide frame 61 and the third guide frame 71 are directly fixed to the inner surface 16 of the second end 12 of the vehicle door glass 1.

[0035] As shown in Figures 3, 4, and 5, the sliding friction force between the first end 11 of the vehicle door glass 1 and the first seal strip 3 is F1, and the sliding friction force between the first guide frame 51 and the first seal strip 3 is F 1Y Therefore, the sliding friction force between the second guide frame 61 and the second seal strip 4 is F 2Y Therefore, the sliding friction force between the third guide frame 71 and the second seal strip 4 is F 2XAnd if the sliding friction force between the second end 12 of the vehicle door glass 1 and the second seal strip 4 is F2, Satisfy the requirements of JPEG0007855734000005.jpg849.

[0036] Since the vehicle door glass 1 is not offset in the Y direction, F 2Y and F 1Y The sizes of F2 and F1 are close to each other, and F 2X Because of the presence of the weight structure 2, the stability of the second end 12 of the vehicle door glass 1 when it lifts and slides is higher than the stability of the first end 11 of the vehicle door glass 1 when it lifts and slides. Therefore, by adding the weight structure 2 to the side of the vehicle door glass 1 closer to the first end 11 at the main support point O, it is possible to increase the stability and balance of the first end 11 of the vehicle door glass 1 and reduce the risk of the first end 11 of the vehicle door glass 1 tilting.

[0037] After the first seal strip 3 and the second seal strip 4 are worn down by prolonged sliding, the amount of wear on the second seal strip 4 generally exceeds that of the first seal strip 3 because the second guide frame 61 and the third guide frame 71 have a longer overall length. However, because the second guide frame 61 and the third guide frame 71 are simultaneously subjected to frictional forces in the X and Y directions between the second seal strip 4 and the second seal strip 4, even after the second seal strip 4 is worn down, the frictional force between the second guide frame 61 and the third guide frame 71 and the second seal strip 4 is still greater than the frictional force between the first guide frame 51 and the first seal strip 3. As a result, the vehicle door glass 1 is still easily tilted towards the second seal strip 4, and gaps are easily formed between the first guide frame 51 and the first seal strip 3, and between the vehicle door glass 1 and the first seal strip 3. The present invention helps to increase the torque value of the vehicle door glass 1 on one side closer to the first guide frame 51 at the main support point O by adding a weight structure 2 between the first guide frame 51 and the main support point O, thereby reducing the risk of the vehicle door glass 1 being offset to the second seal strip 4 and the formation of gaps between the first guide frame 51 and the first seal strip 3 and between the vehicle door glass 1 and the first seal strip 3.

[0038] As shown in Figures 6 to 10, in embodiments of the present invention, the weight structure 2 comprises at least one weight block 21, the vehicle door glass 1 has an inner surface 16 facing inward and an outer surface 17 facing outward, and the weight block 21 is attached to the inner surface 16, outer surface 17 and / or edge of the vehicle door glass 1.

[0039] As shown in Figures 6, 8, and 10, the weight block 21 is attached to the vehicle door glass 1 by mounting fasteners 22, which are attached to the inner surface 16, outer surface 17 and / or edge of the vehicle door glass 1, and the weight block 21 is locked and adhesively fixed to the mounting fasteners 22. With adhesive fixing, the weight block 21 can be fixed by clamping it without preparing any other work clothes. Specifically, the mounting fasteners 22 are provided with at least one slot.

[0040] As shown in Figure 6, in this embodiment, the mounting fastener 22 is provided with a first slot 221 and a second slot 224. The weight block 21 is placed in the first slot 221 and is adhesively fixed to the mounting fastener 22 by the first adhesive layer 222. The edge of the vehicle door glass 1 extends into the second slot 224 and is adhesively fixed by the second adhesive layer 223.

[0041] As shown in Figure 8, in the second embodiment, the mounting fastener 22 is provided with only a first slot 221, and the weight block 21 is hung in the first slot 221 and bonded and fixed by the first adhesive layer 222. The mounting fastener 22 is bonded and fixed to the inner surface 16 or outer surface 17 of the vehicle door glass 1 by the second adhesive layer 223.

[0042] As shown in Figure 10, in the third embodiment, two weight blocks 21 of the same weight are symmetrically hung in the first slots 221 of two mounting fasteners 22 and are adhesively fixed by the first adhesive layer 222. The two mounting fasteners 22 are adhesively fixed symmetrically to the inner surface 16 and outer surface 17 of the vehicle door glass 1 by two second adhesive layers 223.

[0043] Preferably, the weight block is directly attached to the vehicle door glass with tape or directly attached to the vehicle door glass with polyurethane adhesive.
