[0002] The present invention relates to the field of vehicle technology, and particularly to a vehicle door glass assembly, a vehicle door assembly and a vehicle.

Background Art

[0003] Currently, the widely used flush vehicle door glass assembly adheres guide frames to the front end and the rear end of the vehicle door glass. The guide frames are locked to the seal strip on the vehicle door sheet metal rail. The outer surface of the vehicle door glass is flushed with the seal strip, that is, the inner surface of the vehicle door glass, the guide frames and the edges of the vehicle door glass are connected to the seal strip, and the outer surface of the vehicle door glass is not connected to the seal strip. The guide frames and the seal strip can cooperate to provide a better guiding effect for the lift slide of the vehicle door glass. By locking the guide frames and the seal strip during the running of the vehicle, the glass can be more stabilized, so that the glass can be prevented from being shaken by the airflow. However, there is a jamming phenomenon in the lift slide of the glass, the glass is easily offset in its extending direction, and there is a problem of wind and water leakage due to the wear of one - end seal strip.

Modes for Carrying Out the Invention

[0010] In the following, with reference to the drawings according to the embodiments of the present invention, the technical solution according to the embodiments of the present invention will be described more clearly and completely. 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. It should be understood that any other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any innovative ingenuity all belong to the protection scope of the present invention.

[0011] (Embodiment 1) As shown in FIG. 1, the present invention includes a vehicle door main body, a vehicle door glass 1 that is slidably fitted along the lifting direction Z while being sealed to the vehicle door main body and has a first end 11 and a second end 12 facing each other in the longitudinal direction X, and is moved in the lifting direction Z by the drive of a lifting mechanism 9, with the force application point between the lifting mechanism 9 and the main support point O; and 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, 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. While the vehicle door glass 1 is being 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, enhancing the stability of the end with low stability of the vehicle door glass 1 and preventing 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, and avoiding the occurrence of a gap between the end with low stability of the vehicle door glass 1 and the vehicle door main body, thereby preventing the sealing between the vehicle door glass 1 and the vehicle door main 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 lowering 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 and outer surfaces 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 provides the weight structure 2 to enhance the stability during lift-slide and sealing stability of the flush vehicle door glass 1.

[0015] In an embodiment of the present invention, the length of the vehicle door glass 1 extending in the lifting direction Z of the first end 11 is shorter than the length of the vehicle door glass 1 extending in the lifting direction Z of the second end 12, 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 seal sliding fitting surface between the second end 12 of the vehicle door glass 1 and the vehicle door body is larger than the seal 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. For the second end 12 of the vehicle door glass 1, the weight structure 2 is provided close to the first end 11 of the vehicle door glass 1, so that the stability of the first end 11 of the vehicle door glass 1 can be enhanced. Specifically, the vehicle door glass 1 is the vehicle door glass 1 on the vehicle front door, 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 FIG. 1, a weather strip 8 is attached to the vehicle door body, and the vehicle door glass 1 is slidably fitted while being sealed to the weather strip 8 through the weather strip 8 along the lifting direction Z, and the weight structure 2 is located below the weather strip 8. The weight structure 2 always exists in an invisible position of the vehicle door and does not affect the range in which the vehicle door glass 1 lifts and slides. Specifically, when the vehicle door glass 1 is completely closed, the distance between the weight structure 2 and the weather strip 8 is 10 mm or more, and no interference occurs between the weight structure 2 and the weather strip 8.

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

[0018]

Equation

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

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

[0021] In this embodiment, since both the center O2 of the weather strip 8 and the center of gravity O1 of the vehicle door glass 1 are located between the main support point O and the first end 11 of the vehicle door glass 1, M1, M3, and M 車両ドアガラス and M ウェート are all positive numbers, and M2 is a negative number. By providing both the center O2 of the weather strip 8 and the center of gravity O1 of the vehicle door glass 1 on the side closer to the first end 11 of the vehicle door glass 1 of the main support point O, it helps to improve the stability of the first end 11 of the vehicle door glass 1. Desirably, the center of the weather strip is located on the side closer to the second end of the vehicle door glass 1 at the main support point or on the moving path of the main support point. Desirably, the center of gravity of the vehicle door glass is located on the side closer to the second end of the vehicle door glass 1 at the main support point or on the moving path of the main support point, and M 車両ドアガラス is zero. Desirably, the center O2 of the weather strip 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 influence on the lift slide stability and 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 JPEG2025520368000020.jpg31170, where 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 is 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is from 0.1 kg to 2 kg, preferably, the mass is from 0.3 kg to 1.1 kg. If the mass of the weight structure 2 is too heavy, when opening and closing the vehicle door, the impact on the vehicle door glass 1 is too large. If the weight structure 2 is too light, it cannot play a role in enhancing the stability of the first end 11 of the vehicle door glass 1. Since β is 0 degree, the torque generated with respect to the main support point in the X direction of the force received by the vehicle door glass 1 satisfies the following relational expression.

[0025]

Number

[0026] That is, the following relational expression is obtained.

[0027]

Number

[0028] Thereby, the mounting position of the weight structure 2 can be determined.

[0029] As shown in FIG. 1, in the 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 lifting direction Z. The first end 11 of the vehicle door glass 1 is slidably fitted while being sealed to the vehicle door body by the first seal strip 3, and the second end 12 of the vehicle door glass 1 is slidably fitted while being sealed to the vehicle door body by the second seal strip 4. Specifically, as shown in FIGS. 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. However, the inner surface 16 and the edge of the first end 11 of the vehicle door glass 1 are slidably fitted while being sealed to the first seal strip 3, and the inner surface 16 and the edge of the second end 12 of the vehicle door glass 1 are slidably fitted while being sealed to the second seal strip 4.

[0030] As shown in FIG. 3, at least a first limit structure 5 is provided between a first end 11 of the vehicle door glass 1 and a first seal strip 3. As shown in FIGS. 4 and 5, at least one second limit structure 6 and at least one third limit structure 7 are provided between a second end 12 of the vehicle door glass 1 and a second seal strip 4. The first limit structure 5 and the second limit structure 6 cooperate to suppress the movement of the vehicle door glass 1 along its thickness direction Y, and the third limit structure 7 suppresses the movement of the vehicle door glass 1 along its longitudinal direction X. Since the length of the second end 12 of the vehicle door glass 1 extending along the lifting direction Z is long and the length of the first end 11 of the vehicle door glass 1 extending along the lifting direction Z is short, 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 only providing the 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 direction and the Y direction.

[0031] As shown in FIG. 3, in the embodiment of the present invention, the first limit structure 5 includes a first guide frame 51. The first guide frame 51 is mounted on the first end 11 of the vehicle door glass 1 along the lifting direction Z. A first guide groove 52 is formed in the first seal strip 3 along the lifting direction. The first guide groove 52 is provided with two first limit surfaces 53 facing each other in the thickness direction Y of the vehicle door glass 1. The first guide frame 51 is abutted against the two first limit surfaces 53 and slides in the first guide groove 52. Specifically, in FIG. 3, the reference numeral 51 indicates a cross-section of the same first guide frame 51. As shown in FIG. 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 the first stand 13. The first seal strip 3 is further provided with a first mounting groove 31 along the lifting direction Z. 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 while being sealed to the inner surface 16 of the first end 11 of the vehicle door glass 1, and the second lip 33 is slidably fitted while being sealed to the edge of the first end 11 of the vehicle door glass 1.

[0032] As shown in FIGS. 4 and 5, the second limit structure 6 includes a second guide frame 61, and the third limit structure 7 includes 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 lifting direction Z. The second seal strip 4 is provided with a second guide groove 62 along the lifting direction. The second guide groove 62 is provided with two second limit surfaces 63 and two third limit surfaces 73. The two second limit surfaces 63 are provided facing each other in the thickness direction Y of the vehicle door glass 1, and the two third limit surfaces 73 are provided facing each other in the longitudinal direction X of the vehicle door glass 1. The second guide frame 61 is abutted against the two second limit surfaces 63 and is slidable in the second guide groove 62, and the third guide frame 71 is abutted against the two third limit surfaces 73 and is slidable in the second guide groove 62.

[0033] Specifically, in FIG. 4, reference numeral 61 indicates a cross-section of the same second guide frame 61. In FIG. 5, reference numeral 71 indicates a cross-section of the same third guide frame 71. As shown in FIG. 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 at intervals between the two third guide frames 71. The second seal strip 4 is further provided with a second mounting groove 41 along the lifting direction Z. The second mounting groove 41 communicates with the second guide groove 62 and the third guide groove 72, and is fitted to the second end 12 of the vehicle door glass 1. At least one third lip 42 and at least one fourth lip 43 are provided in the second mounting groove 41. The third lip 42 is slidably fitted while being sealed to the inner surface 16 of the second end 12 of the vehicle door glass 1, and the fourth lip 43 is slidably fitted while being sealed to the edge of the second end 12 of the vehicle door glass 1.

[0034] As shown in FIGS. 2 and 7, in this embodiment and the second embodiment, the two first guide frames 51 and the first stand 13 are integrally formed. The three second guide frames 61, the two third guide frames 71 and the second stand 14 are integrally formed. As shown in FIG. 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 FIGS. 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 and the sliding friction force between the second guide frame 61 and the second seal strip 4 is F 2Y and the sliding friction force between the third guide frame 71 and the second seal strip 4 is F 2XWhen the sliding frictional force between the second end 12 of the vehicle door glass 1 and the second seal strip 4 is F2, It satisfies JPEG2025520368000023.jpg849.

[0036] Since the vehicle door glass 1 is not offset in the Y direction, F 2Y and F 1Y are close to each other in magnitude, the magnitudes of F2 and F1 are close to each other, and since F 2X exists, the stability of the second end 12 of the vehicle door glass 1 during lift-slide is higher than that of the first end 11 of the vehicle door glass 1 during lift-slide. Therefore, by adding the weight structure 2 to the side closer to the first end 11 of the vehicle door glass 1 at the main support point O, it helps to increase the stability and balance of the first end 11 of the vehicle door glass 1, and can 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 out by long-term sliding, since the total lengths of the second guide frame 61 and the third guide frame 71 are long, the wear amount of the second seal strip 4 generally exceeds that of the first seal strip 3. However, since the second guide frame 61 and the third guide frame 71 and the second seal strip 4 simultaneously receive frictional forces in the X direction and the Y direction, even if the second seal strip 4 is worn out, 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. The vehicle door glass 1 still tends to tilt towards the second seal strip 4, and gaps are likely to be 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 adds a weight structure 2 between the first guide frame 51 and the main support point O, which helps to increase the torque value of the vehicle door glass 1 on the side close to the first guide frame 51 at the main support point O, and reduces the risk that the vehicle door glass 1 is offset towards the second seal strip 4 and gaps are 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.

[0038] As shown in FIGS. 6 to 10, in an embodiment of the present invention, the weight structure 2 includes at least one weight block 21. The vehicle door glass 1 has an inner surface 16 facing the inside of the vehicle and an outer surface 17 facing the outside of the vehicle. The weight block 21 is mounted on the inner surface 16, the outer surface 17 and / or the edge of the vehicle door glass 1.

[0039] As shown in FIGS. 6, 8 and 10, the weight block 21 is mounted on the vehicle door glass 1 by a mounting locking device 22. The mounting locking device 22 is mounted on the inner surface 16, the outer surface 17 and / or the edge of the vehicle door glass 1. The weight block 21 is locked to the mounting locking device 22 and adhesively fixed. In the case of fixing by an adhesive, the weight block 21 can be fixed by sandwiching it without preparing other work clothes. Specifically, at least one slot is provided in the mounting locking device 22.

[0040] As shown in FIG. 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 hung on the first slot 221 and 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 FIG. 8, in the second embodiment, the mounting fastener 22 is only provided with a first slot 221. The weight block 21 is hung on the first slot 221 and adhesively fixed by the first adhesive layer 222. The mounting fastener 22 is adhesively fixed to the inner surface 16 or the outer surface 17 of the vehicle door glass 1 by the second adhesive layer 223.

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

[0043] Preferably, the weight block is adhesively fixed directly to the vehicle door glass by tape or directly to the glass of the vehicle door by a polyurethane adhesive.
