Description

Technical Field

[0001] The utility model relates to the technical field of vehicle auxiliary components, and in particular to a door glass lifting and buffering structure. The utility model also relates to a door provided with the door glass lifting and buffering structure, and a vehicle provided with the door. Background Art

[0002] With the continuous development of society, private cars have gradually become popular in people's lives, and consumers have higher and higher requirements for the quality of vehicles. Among them, the car door is usually equipped with a door glass for the driver or passengers to observe the external environment of the car. In order to facilitate the opening of the door glass, a door glass lifting mechanism is usually provided inside the door to drive the door glass to rise and fall.

[0003] Most traditional door glass lifting mechanisms use electric drive, where the motor drives the lead screw, worm gear and other transmission mechanisms to drive the glass holder to move along the guide rail, thereby achieving the lifting and lowering of the door glass. During the lifting process, although the transmission mechanism can reduce the movement speed of the glass by designing a deceleration device, due to inertia, the glass holder carrying the door glass may generate a large impact force and noise when it reaches the top or bottom of the guide rail. This will not only affect the comfort of passengers in the car, but may also cause damage to the lifting mechanism itself. Therefore, a buffer structure is usually provided in the lifting mechanism of the door glass to reduce the impact or noise caused by the lifting and lowering of the door glass.

[0004] In the existing door glass lifting buffer structure, a buffer block is usually arranged on the glass bracket supporting the door glass. When the glass bracket moves to the top or bottom of the guide rail, the buffer block abuts against the limit mechanism of the guide rail, so that the buffer block can buffer the glass bracket and avoid the impact and noise. However, since the buffer block is arranged on the glass bracket and moves with the glass bracket, when the buffer block is deformed due to long-term use, the deformed buffer block is easy to rub against the guide rail or other components on the guide rail, generating abnormal noise, thereby reducing the driving experience of the driver and passengers, which is not conducive to improving the quality of the whole vehicle. Utility Model Content

[0005] In view of this, the utility model aims to propose a door glass lifting buffer structure to prevent the buffer block from deforming and scratching against the guide rail, thereby preventing the generation of abnormal noise, thereby helping to improve the quality of the entire vehicle.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] A door glass lifting and lowering buffer structure comprises a glass bracket connected to the door glass, and a buffer block located at the bottom end of the glass bracket lifting and lowering track; the buffer block is arranged on a fixed base connected to a guide rail, the fixed base is provided with a mounting groove, the bottom of the buffer block is embedded in the mounting groove, and an anti-slip portion is provided between the buffer block and the fixed base; the anti-slip portion constrains the buffer block in the mounting groove and can limit the buffer block from slipping out of the mounting groove.

[0008] Furthermore, a fixed pulley for steering the cable of the glass lifter is provided on the guide rail, and a mounting seat of the fixed pulley constitutes the fixed base.

[0009] Furthermore, the glass bracket is provided with an outwardly projecting protruding structure, and when the glass bracket descends to the bottom end, the protruding structure abuts against the buffer block.

[0010] Furthermore, the anti-slip portion includes an opening provided on the inner wall of the mounting groove, and a limiting rib provided on the side of the buffer block, and the limiting rib is inserted into the opening.

[0011] Furthermore, the anti-slip portions are respectively provided on at least two opposite sides of the buffer block.

[0012] Furthermore, a buffer groove is provided on the top of the buffer block.

[0013] Furthermore, the buffer grooves are multiple and are arranged at intervals on the top of the buffer block; and / or the buffer grooves are long strip grooves with at least one end open.

[0014] Furthermore, the top of the buffer block is in an upwardly arched arc shape, and the buffer groove is provided at least in the center of the top of the buffer block.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] The vehicle door glass lifting and lowering buffer structure described in the utility model sets the buffer block on a fixed basis connected to the guide rail so that the buffer block does not move with the lifting and lowering of the glass bracket, thereby preventing the buffer block from being deformed due to buffering and rubbing against the guide rail or other components on the guide rail, thereby preventing abnormal noise when the vehicle door glass is lifted and lowered, which is beneficial to improving the quality of the entire vehicle.

[0017] A fixed pulley for turning the wire of the glass lifter is provided on the guide rail, and the mounting seat of the fixed pulley constitutes a fixed base, so that the fixed base is integrated on the mounting seat, the compactness of the door glass lifting buffer structure is improved, and the occupancy of the internal space of the door is retrieved.

[0018] The glass holder is provided with an outwardly projecting protruding structure. When the glass holder descends to the bottom, the protruding structure abuts against the buffer block, and has good structural strength. When the glass holder abuts against the buffer block, the buffer block can effectively buffer the glass holder through the protruding structure.

[0019] The anti-slip portion includes an opening arranged on the inner wall of the mounting groove and a limiting rib arranged on the side of the buffer block. When the buffer block is embedded in the mounting groove, the limiting rib on the buffer block can be embedded in the opening on the inner wall of the mounting groove. Through the cooperation between the opening and the limiting rib, the buffer block is prevented from detaching from the mounting groove, thereby improving the stability of the buffer block fixation.

[0020] Anti-slip portions are respectively provided on at least two opposite sides of the buffer block. By providing the anti-slip portions on the two opposite sides, the buffer block can be fixed from two opposite sides of the buffer block, thereby further improving the stability of the fixation of the buffer block.

[0021] The top of the buffer block is provided with a buffer groove, which can reduce the contact area between the buffer block and the glass bracket to a certain extent. At the same time, the buffer groove provides a certain deformation space for the force deformation of the buffer block, thereby reducing the impact force of the glass bracket on the buffer block and improving the buffering effect of the buffer block.

[0022] The buffer grooves are multiple ones arranged at intervals on the top of the buffer block, which can further reduce the contact area between the buffer block and the glass bracket, and provide a certain deformation space for the stress deformation of the buffer block, thereby improving the buffer effect of the buffer block. The buffer groove is a long strip groove with at least one end open, which can prevent the convex structure of the glass bracket and the buffer block from sealing part of the air in the buffer groove, preventing the air in the buffer groove from being unable to be discharged, which makes the buffer groove difficult to deform, thereby improving the buffer effect of the buffer block.

[0023] The top of the buffer block is in an arc shape that arches upward. When the glass holder moves toward the buffer block and contacts the buffer block, the contact area between the buffer block and the glass holder gradually increases. Compared with a flat surface of the top of the buffer block, the impact force can be reduced, thereby improving the buffering effect of the buffer block on the glass frame. At the same time, a buffer groove is provided at least in the center of the top of the buffer block. The glass holder first contacts the central part of the top of the buffer block. The buffer groove provided in the central part can improve the buffering effect of the buffer block on the glass holder.

[0024] Another object of the present invention is to provide a vehicle door, in which the vehicle door is provided with the vehicle door glass lifting and lowering buffer structure as described above. The present invention also provides a vehicle provided with the vehicle door as described above.

[0025] The vehicle, door and door glass lifting and lowering buffer structure described in the utility model have the same technical effects as those of the prior art, and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] Embodiment 1

[0046] This embodiment relates to a door glass lifting and lowering buffer structure, which is used to buffer the door glass when the door glass is lifted and lowered. Figure 1 , Figure 2 , Figure 3 As shown, in terms of overall structure, the door glass lifting buffer structure of this embodiment includes a glass bracket 1 connected to the door glass, and a buffer block 2 located at the bottom end of the lifting track of the glass bracket 1.

[0047] Among them, the buffer block 2 is arranged on a fixed base connected to the guide rail 3, and the fixed base is arranged at the bottom end of the guide rail 3, so that when the glass holder 1 drives the door glass to move downward, the glass holder 1 can abut against the buffer block 2. At the same time, a mounting groove 4 is provided on the fixed base, and the bottom of the buffer block 2 is embedded in the mounting groove 4. In addition, an anti-slip portion is provided between the buffer block 2 and the fixed base. The anti-slip portion constrains the buffer block 2 in the mounting groove 4, and can limit the buffer block 2 from slipping out of the mounting groove 4. It can be understood that the buffer block 2 does not move with the glass frame, and even if the buffer block 2 is deformed due to the impact of the glass holder 1, there will be no relative movement between the buffer block 2 and the guide rail 3, thereby avoiding the occurrence of scratches.

[0048] As described above, by setting the buffer block 2 on a fixed basis connected to the guide rail 3, the buffer block 2 does not move with the lifting and lowering of the glass bracket 1, which can prevent the buffer block 2 from being scratched against the guide rail 3 or other components on the guide rail 3 due to buffering deformation, thereby preventing abnormal noise when the door glass is lifted or lowered, which is beneficial to improving the quality of the entire vehicle.

[0049] Based on the overall introduction above, specifically, one side of the guide rail 3 of this embodiment is connected to a glass lifter 5 for driving the glass bracket 1 to move along the guide rail 3, and a plurality of pull wires 6 are led out from both ends of the glass lifter 5. The pull wires 6 are connected to one end of the glass bracket 1 after passing through the fixed pulley 301 for deflection. In addition, the pull wires 6 are connected to both the upper and lower ends of the glass bracket 1. When the glass lifter 5 is started, the pull wires 6 can drive the glass bracket 1 to move along the guide rail 3, thereby realizing the lifting and lowering of the door glass.

[0050] In specific implementation, the outer sleeve of the cable 6 between the glass lifter 5 and the fixed pulley 301 is provided with a sleeve 501, and the cable 6 can slide in the sleeve 501. The setting of the sleeve 501 can prevent the cable 6 from rubbing against the inside of the door when it moves, thereby avoiding damage to the cable 6 due to friction and improving the service life of the cable 6. At the same time, it can avoid abnormal noise caused by friction between the cable 6 and the door to a certain extent, thereby improving the quality of the whole vehicle. In addition, the buffer block 2 can be made of a buffer material well known to those skilled in the art, such as rubber, etc., which can play a buffering role when deformed by external impact, and the guide rail 3 can be fixedly connected to the inner space of the door by screwing or riveting.

[0051] Since the fixed pulley 301 is located on the lifting track of the glass bracket 1 so that the cable 6 is turned to connect to the glass bracket 1, and the buffer block 2 is also located at the bottom of the lifting track of the glass bracket 1, in order to improve the compactness of the door glass lifting buffer structure, the guide rail 3 of this embodiment is provided with a fixed pulley 301 for turning the cable 6 of the glass lifter 5, and the mounting seat 302 of the fixed pulley 301 constitutes a fixed base. Thus, the fixed base is integrated on the mounting seat 302 of the fixed pulley 301, so that the buffer block 2 can be fixed on the mounting seat 302, thereby improving the compactness of the door glass lifting buffer structure of this embodiment, so as to reduce the occupation of the internal space of the door. At the same time, the fixed pulley 301 and the arrangement on the guide rail 3 can facilitate the assembly of the door glass lifting buffer structure to a certain extent.

[0052] In a specific implementation, in addition to the fixed pulley 301 and the mounting seat 302 loaded with the fixed pulley 301, the glass lifter 5 for driving the glass lifting bracket is also connected to the guide rail 3, so as to facilitate the assembly operation of the door glass lifting buffer structure. In addition, the guide rail 3 can be fixedly connected to the inner space of the door by screwing or riveting, which has a good fixing effect. In addition, in addition to integrating the fixing base on the mounting seat 302, the fixing base can also be an independent component connected to the guide rail 3, or integrated on other structures of the guide rail 3, which can buffer the glass bracket 1.

[0053] In order to make the buffer block 2 effectively buffer the glass bracket 1, Figure 4 As shown, the glass holder 1 of this embodiment is provided with an outwardly projecting protruding structure 101, and when the glass holder 1 descends to the bottom, the protruding structure 101 abuts against the buffer block 2. Specifically, the protruding structure 101 is formed by the middle part of the glass holder 1 protruding toward the guide rail 3, and the protruding structure 101 has a certain thickness in the moving direction of the glass holder 1, and the protruding structure 101 is arranged in the middle part of the glass holder 1, and has a good connection strength with the glass holder 1, so that the buffer block 2 abuts against the protruding structure 101 to buffer the glass holder 1.

[0054] In addition, it can be understood that the protruding structure 101 is arranged in the middle of the side of the glass holder 1 facing the guide rail 3, and is used to abut the buffer block 2. When the glass holder 1 abuts on the buffer block 2, the buffer block 2 can be located between the glass holder 1 and the guide rail 3. Compared with the buffer block 2 directly abutting on one side of the glass holder 1, the moving stroke of the glass frame can be improved to a certain extent, thereby reducing the size of the guide rail 3 when the door glass lifting distance is constant, so as to further reduce the occupation of the door interior space by the door glass lifting buffer structure.

[0055] In order to improve the fixing effect of the mounting groove 4 on the buffer block 2, as Figure 5 , Figure 6 As shown, the anti-dropping part of this embodiment includes an opening 401 provided on the inner wall of the installation groove 4, and a limiting rib 201 provided on the side of the buffer block 2, and the limiting rib 201 is inserted into the opening 401. Through the arrangement of the opening 401 and the limiting rib 201, when the buffer block 2 is embedded in the installation groove 4, the limiting rib 201 on the buffer block 2 can be embedded in the opening 401, thereby preventing the buffer block 2 from falling off from the installation groove 4, and improving the stability of the buffer block 2 in the installation groove 4. In specific implementation, as shown in FIG. Figure 7As shown, the anti-slip portion can also adopt another embodiment. In this embodiment, the anti-slip portion includes an anti-slip protrusion 402 formed on the inner wall of the mounting groove 4, and a groove formed on the buffer block 2. When the buffer block 2 is embedded in the mounting groove 4, the anti-slip protrusion 402 can be snapped into the groove, thereby fixing the buffer block 2 and preventing the buffer block 2 from falling off.

[0056] Among them, at least two opposite sides of the buffer block 2 of this embodiment are respectively provided with anti-slip parts, and fixation is achieved from two opposite sides of the buffer block 2, which can further improve the fixing effect of the installation groove 4 on the buffer block 2, thereby improving the stability of the fixation of the buffer block 2.

[0057] In order to reduce the impact force of the glass bracket 1 on the buffer, Figure 3 , Figure 6 As shown, a buffer groove 202 is provided on the top of the buffer block 2 of the present embodiment. The setting of the buffer groove 202 can reduce the contact area between the buffer block 2 and the glass holder 1 to a certain extent. At the same time, the setting of the buffer groove 202 provides a certain deformation space for the force deformation of the buffer block 2, thereby helping to reduce the impact force of the glass holder 1 on the buffer block 2 and enhance the buffering effect of the buffer block 2.

[0058] Specifically, in order to improve the buffering effect of the buffer block 2, the buffer grooves 202 of this embodiment are arranged at intervals on the top of the buffer block 2, which can further reduce the contact area between the buffer block 2 and the glass holder 1, and provide a certain deformation space for the force deformation of the buffer block 2. In the specific implementation, the buffer grooves 202 are arranged in two, so that the buffer block 2 has a good buffering effect and can avoid the buffer grooves 202 being easily worn due to too many buffer grooves 202, thereby improving the durability of the buffer block 2.

[0059] The buffer groove 202 is a long strip groove with at least one end open. It is understandable that if the two ends of the long strip groove are not open, when the glass holder 1 abuts against the buffer block 2, the protruding structure 101 of the glass holder 1 and the buffer block 2 will close the buffer groove 202, and the air in the buffer groove 202 cannot be discharged, so that part of the buffer block 2, that is, the buffer groove 202 part, is difficult to deform, thereby affecting the buffering effect of the buffer block 2. In a specific implementation, both ends of the buffer groove 202 are open to ensure the discharge of gas in the buffer groove 202.

[0060] In order to further improve the buffering effect of the buffer block 2, as Figure 3 , Figure 6As shown, the top of the buffer block 2 of this embodiment is in an arc shape that arches upward, and a buffer groove 202 is provided at least in the center of the top of the buffer block 2. By configuring the top of the buffer block 2 to be arc-shaped, when the glass holder 1 moves downward and abuts against the buffer block 2, the convex structure 101 of the glass holder 1 first contacts the central part of the top of the buffer block 2, and the central part is provided with the above-mentioned buffer groove 202. At this time, the contact area between the buffer block 2 and the glass holder 1 is small. As the glass holder 1 moves, the buffer block 2 is compressed and deformed, and the contact area between the top of the buffer block 2 and the glass frame gradually increases. By gradually increasing the contact area between the buffer block 2 and the glass holder 1, the impact force can be reduced compared with the arrangement of the top of the buffer block 2 as a plane, thereby improving the buffering effect of the buffer block 2 on the glass frame. In addition, the top of the buffer block 2 is arranged in an arc shape, which is conducive to the deformation of the central part of the top of the buffer block 2, and prevents the pressure on the middle part of the top of the buffer block 2 from being too large when the top of the buffer block 2 is pressed, resulting in the rupture of the buffer block 2 during long-term use, thereby improving the durability of the buffer block 2.

[0061] In summary, the door glass lifting and lowering buffer structure of the present embodiment sets the buffer block 2 on a fixed basis connected to the guide rail 3, so that the buffer block 2 does not move with the lifting and lowering of the glass bracket 1, and can avoid the buffer block 2 from scratching the guide rail 3 or other components on the guide rail 3 due to buffering deformation, thereby preventing abnormal noise when the door glass is lifted and lowered, which is beneficial to improving the quality of the entire vehicle.
