Description

Technical Field

[0001] This invention relates to the field of vehicle component technology, and in particular to a door window lifting mechanism. Furthermore, this invention relates to a door window lifting system having the door window lifting mechanism, and a car door having the door window lifting system. Background Technology

[0002] As a crucial component of a vehicle, the power window regulator is installed on the door and used to open and close the door window. Existing power window regulators generally consist of a motor, slider, guide rail, and cable. The motor drives the slider, which in turn moves the glass up and down along the guide rail, thus raising or lowering the window. However, for sports cars or high-end vehicles, to enhance their premium and stylish appeal, frameless doors are typically used. Since frameless doors lack an upper window frame, using existing power window regulator installation structures would prevent adjustment of the door window's position and hinder coordination between the door window and other components. Summary of the Invention

[0003] In view of this, the present invention aims to provide a door window lifting mechanism that can adjust the position of the door window along the length and / or height of the vehicle body.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A car door window lifting mechanism includes a guide rail disposed on the car door and a slider slidably disposed on the guide rail. The slider is provided with a mounting component for mounting the car door window, and a first adjustment part is provided between the slider and the mounting component. The position of the mounting component can be adjusted along the length direction and / or height direction of the car body through the first adjustment part, and a fixing part is provided on the slider to fix the adjusted mounting component.

[0006] Furthermore, the first adjustment part includes a plug provided on the mounting member and a socket provided on the slider. The plug is constrained in the socket and can slide within the socket along the length direction of the vehicle body and / or the height direction of the vehicle body.

[0007] Furthermore, the plug-in includes a sliding portion and a limiting portion connected to the end of the sliding portion. The sliding portion passes through the socket, and the limiting portion blocks one side of the socket, thereby constraining the sliding portion within the socket.

[0008] Furthermore, the slider is provided with a mounting through hole communicating with the socket. The limiting part passes through the mounting through hole to the slider, and the sliding part enters the socket through the mounting through hole. When the sliding part enters the socket, the limiting part blocks one side of the socket.

[0009] Furthermore, the fixing part includes a fixing hole provided on the slider, a fixing through hole provided on the mounting member, and a fixing member that passes through the fixing hole and is fixed in the fixing through hole, and the inner diameter of the fixing hole is larger than that of the fixing through hole.

[0010] Furthermore, the mounting component has two clips arranged opposite each other, and the door glass is mounted between the two clips;

[0011] One of the clips is provided with a locking post, and the other clip is provided with a locking groove. The locking post passes through the door glass and is engaged in the locking groove. The fixing hole passes through both the locking post and the locking groove.

[0012] Furthermore, the guide rail is connected to the vehicle door via a second adjustment part, which allows the position of the guide rail to be adjusted along the width direction of the vehicle body.

[0013] Furthermore, the second adjusting part includes an adjusting column, which is provided with a limiting shoulder and external threads at both ends of the adjusting column;

[0014] One end of the adjusting column is screwed to the guide rail, and the other end of the adjusting column passes through the car door and is screwed to a nut located on one side of the car door. The limiting shoulder and the nut respectively abut against both sides of the car door.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The door window lifting mechanism of the present invention provides a first adjustment part between the slider and the mounting part, and the position of the mounting part can be adjusted along the length direction and / or height direction of the vehicle body through the first adjustment part, so that the door window mounted on the mounting part can be adjusted to a suitable position, thereby facilitating the cooperation between the door window and other parts of the vehicle body.

[0017] Furthermore, the first adjustment section adopts a plug-in and socket structure, and the plug-in can slide within the socket along the length and / or height direction of the vehicle body. This structure is simple and easy to design and implement. The plug-in includes a sliding part and a limiting part, which can both insert the plug-in into the socket and prevent the plug-in from falling out of the socket when the mounting part is in position. By providing a mounting through hole on the slider that communicates with the socket, the plug-in can be both inserted into the socket and constrained within the socket. This structure is relatively simple and easy to manufacture.

[0018] Secondly, setting the inner diameter of the fixing hole to be larger than that of the fixing through hole facilitates fixing the mounting component to the slider after adjusting its position. By designing the mounting component with two clamping pieces, one of which has a slot and the other has a locking post that engages with the slot, and by ensuring that the fixing through hole extends through both the locking post and the slot, the door glass can be fixed to the mounting component simultaneously while the mounting component is being fixed to the slider, thus improving assembly efficiency.

[0019] Furthermore, the guide rail is mounted on the door via a second adjustment unit, which allows the position of the guide rail to be adjusted along the width of the vehicle body. This not only adjusts the position of the door glass in the width direction of the vehicle body but also serves as the mounting point for the guide rail, thereby reducing the number of parts. The second adjustment unit includes an adjustment column with external threads at both ends, allowing the guide rail to be adjusted along the width direction of the vehicle body by rotating the adjustment column. This structure is simple and easy to operate.

[0020] Another object of the present invention is to provide a car door window lifting system, including the car door window lifting mechanism as described above, and further including a drive unit that is pulsatically connected to the slider, the drive unit being fixed to the car door.

[0021] Furthermore, the present invention also relates to a car door, wherein the car door is provided with a door glass lifting system as described above.

[0022] The automotive door and door window lifting system described in this invention have the same beneficial effects as the aforementioned door window lifting mechanism compared to the prior art, and will not be repeated here. Attached Figure Description

[0050] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] Example 1

[0052] This embodiment relates to a car door glass lifting mechanism, which has a guide rail 2 disposed on the car door 1 and a slider 6 slidably disposed on the guide rail 2. A mounting part 4 for mounting the car door glass 5 is provided on the slider 6, and a first adjustment part is provided between the slider 6 and the mounting part 4.

[0053] The position of the mounting piece 4 can be adjusted along the length and height of the vehicle body via the first adjustment part, and a fixing part for fixing the adjusted mounting piece 4 is provided on the slider 6.

[0054] The door window lifting mechanism of this embodiment provides a first adjustment part between the slider 6 and the mounting part 4. The position of the mounting part 4 can be adjusted along the length and / or height of the vehicle body through the first adjustment part, so that the door window 5 installed on the mounting part 4 can be adjusted to a suitable position, thereby facilitating the cooperation between the door window 5 and other parts of the vehicle body.

[0055] Based on the above overview, an exemplary structure of the vehicle door window lifting mechanism in this embodiment is described below. Figure 1 and Figure 2 As shown in the diagram, similar to existing technologies, the door 1 in this embodiment also includes an outer door panel, an inner door panel 101, and a door reinforcing plate 102 disposed on the inner door panel 101. To improve the lifting and lowering effect of the door glass 5, the guide rails 2 in this embodiment are two oppositely arranged, and each guide rail 2 is provided with a mounting component 4 for installing the door glass 5. This arrangement not only improves the installation stability of the door glass 5, but also improves the stability of the lifting and lowering of the door glass 5.

[0056] Furthermore, the mounting structures of the two guide rails 2 and the two sliders 6 on the guide rails 2 are the same. The following description will only take one side of the guide rail 2 and slider 6 as an example.

[0057] In addition, similar to the prior art, each slider 6 is connected to the drive unit via a pull wire 7, and both sliders 6 are connected to the same drive unit. The connection structure between the pull wire 7 and the slider 6 can refer to the prior art.

[0058] In this embodiment, the drive unit specifically adopts a motor 3, and the motor 3 is not connected to the guide rail 2. It is directly mounted on the door 1 via a motor mount 11, so there is no need to adjust the position of the motor 3. The structure and connection relationship between the guide rail 2 and the slider 6 will be described first, and then the installation structure of the motor 3 will be described.

[0059] Specifically, the assembly structure between slider 6 and mounting component 4 refers to... Figures 3 to 6 As shown, the aforementioned fixing part includes a fixing hole 603 on the slider 6, a fixing through hole 402 on the mounting member 4, and a fixing member that passes through the fixing hole 603 and is fixed in the fixing through hole 402. Furthermore, the inner diameter of the fixing hole 603 is larger than that of the fixing through hole 402. This design facilitates the fixing of the mounting member 4 on the slider 6 after adjusting its position. The first adjustment part of this embodiment includes a plug 401 on the mounting member 4 and a socket 605 on the slider 6. The plug 401 is constrained in the socket 605 and can slide within the socket 605 along the length direction and / or height direction of the vehicle body.

[0060] The structure of the slider 6 in this embodiment is as follows: Figure 7 and Figure 8 As shown, and based on Figure 7 As shown in the diagram, a groove 601 for engaging with the guide rail 2 is provided on the right side of the slider 6, and a fixing hole 603 is specifically located on the left side of the slider 6. As one specific implementation, such as... Figure 6 As shown, the fixing hole 603 in this embodiment is a rectangular hole, and the slider 6 has a recessed receiving groove 602 formed at the position where the fixing hole 603 is located. The fixing component in this embodiment is a screw, and the fixing through hole 402 is a threaded hole. With this arrangement, the screw can pass through the fixing hole 603 and be screwed into the fixing through hole 402, and the head of the screw is accommodated in the receiving groove 602.

[0061] It should be noted that the fixing through hole 402 can be a rectangular hole, an elliptical hole, or an irregular hole, and the fastener can also be a bolt. In this case, it is also feasible to screw the fastener through the fixing hole 603 and the fixing through hole 402 and then screw it with the nut.

[0062] Still by Figure 6 and Figure 7 As shown, to improve the stability of the position adjustment of the mounting component 4, there are two insertion holes 605, and the two insertion holes 605 are respectively provided on both sides of the fixing hole 603. In addition, to facilitate the installation of the mounting component 4 on the slider 6, a hook 606 is provided on the slider 6 located below the lower insertion hole 605. The bottom end of the mounting component 4 can be locked in the hook 606 to achieve the pre-positioning of the mounting component 4.

[0063] Furthermore, as a specific implementation, the insertion hole 605 on the slider 6 is a rectangular hole extending along the sliding direction of the slider 6 (i.e., the height direction of the vehicle body). This allows the insert 401 to slide along the length of the insertion hole 605, thereby adjusting the position of the mounting part 4 along the height direction of the vehicle body. To improve the usability, the slider 6 is further provided with a mounting through hole 604 communicating with the insertion hole 605. This mounting through hole 604 is a rectangular hole extending perpendicular to the sliding direction of the slider 6, that is, the mounting through hole 604 and the insertion hole 605 together form a T-shaped hole.

[0064] The structure of mounting component 4 in this embodiment is as follows: Figures 9 to 11 As shown, the mounting component 4 has two opposing clips 403, and the door glass 5 is mounted between the two clips 403. And based on... Figure 11As shown in the diagram, the left clamping piece 403 has a locking post 404, and the right clamping piece 403 has a locking groove. The locking post 404 passes through the door glass 5 and engages in the locking groove, thus achieving pre-positioning of the door glass 5 on the mounting component 4. To improve the installation stability of the door glass 5, the aforementioned fixing through hole 402 extends through both the locking post 404 and the locking groove. Therefore, when the door glass 5 is clamped between the two clamping pieces 403, manually pressing the two clamping pieces 403 will engage the locking post 404 in the locking groove. Then, a screw is passed through the fixing hole 603 and screwed into the fixing through hole 402. This not only fixes the mounting component 4 to the slider 6 but also secures the door glass 5 to the mounting component 4, improving assembly efficiency.

[0065] like Figure 9 and Figure 10 As shown, there are two plugs 401 on the mounting component 4, corresponding to the socket 605. These two plugs 401 are positioned on both sides of the fixing through hole 402. Furthermore, each plug 401 includes a sliding portion 4011 and a limiting portion 4012 connected to the end of the sliding portion 4011. The sliding portion 4011 passes through the socket 605, and the limiting portion 4012 blocks one side of the socket 605, thereby constraining the sliding portion 4011 within the socket 605 to prevent the sliding portion 4011 from dislodging from the socket 605.

[0066] Specifically, in this embodiment, plug-in 401 presents... Figure 9 The T-shaped structure shown has a vertical portion forming a sliding portion 4011 and a horizontal portion forming a limiting portion 4012. That is, the width of the limiting portion 4012 is greater than that of the sliding portion 4011, and the width of the sliding portion 4011 is less than that of the insertion hole 605, so that the plug 401 can slide in the insertion hole 605 along the length direction of the vehicle body, thereby adjusting the position of the mounting piece 4 in the length direction of the vehicle body.

[0067] Based on the aforementioned structure of the mounting through-hole 604 and the insertion hole 605, the limiting portion 4012 can pass through the mounting through-hole 604 to the slider 6, while the sliding portion 4011 enters the insertion hole 605 through the mounting through-hole 604. When the sliding portion 4011 enters the insertion hole 605, due to the larger width of the limiting portion 4012, it is blocked on one side of the insertion hole 605, thereby preventing the plug-in 401 from coming out of the insertion hole 605. It should be noted that the mounting through-hole 604 communicating with the insertion hole 605 may not be provided. In this case, it is also feasible to use a structure with a flexible locking head, such as a snap-fit, for the plug-in 401. In this case, the flexible locking head of the plug-in 401 can also be squeezed through the hole wall of the insertion hole 605 and pass through the insertion hole 605, and the flexible locking head is locked on one side of the insertion hole 605. Alternatively, the limiting portion 4012 can be connected by adhesive or other methods after the sliding portion 4011 passes through the insertion hole 605.

[0068] By setting up the above structure, after loosening the fastener, the insert 401 can be slid along the length direction of the insertion hole 605 to adjust the position of the door glass 5 in the vehicle body height direction. In addition, the insert 401 can be slid along the width direction of the insertion hole 605 to adjust the position of the door glass 5 in the vehicle body length direction, thereby allowing the door glass 5 to be adjusted to a suitable position.

[0069] Furthermore, in this embodiment, to further improve the usability, the guide rail 2 is connected to the door 1 via a second adjustment part. This second adjustment part allows the position of the guide rail 2 to be adjusted along the width of the vehicle body, thereby adjusting the position of the door glass 5 in the width direction of the vehicle body. As one specific implementation method, such as... Figure 1 As shown, the second adjustment part is located at the top of the guide rail 2, while the bottom of the guide rail 2 is connected to the inner door panel 101 via the bracket 8. Alternatively, second adjustment parts can be provided at both ends of the guide rail 2, and the guide rail 2 can be fixed to the door 1 via the two second adjustment parts.

[0070] Combination Figures 12 to 14 As shown, the second adjustment part of this embodiment includes an adjustment column 9, on which a limiting shoulder 901 is provided, and external threads are provided at both ends of the adjustment column 9. One end of the adjustment column 9 is screwed to the guide rail 2, and the other end of the adjustment column 9 passes through the door reinforcement plate 102 and the inner door panel 101, and is screwed to a nut 10 located on one side of the inner door panel 101. The limiting shoulder 901 and the nut 10 respectively abut against both sides of the door 1.

[0071] Furthermore, the base of the guide rail 2 is detachably connected to the bracket 8 via bolts. Because the guide rail 2 has a certain length, the position of the top of the guide rail 2 in the vehicle width direction can be adjusted only via the second adjustment part. In specific operation, after loosening the nut 10, rotating the adjusting column 9 changes the screwed position of the guide rail 2 on the adjusting column 9. Once adjusted to the appropriate position, the nut 10 can be re-secured.

[0072] In addition, to reduce the number of parts, such as Figure 15 As shown in the diagram, in this embodiment, the motor 3, the motor mount 11, and the door reinforcement plate 102 are connected together by the same connector 12. The structure of the connector 12 is as follows: Figure 16 As shown, its overall structure is the same as the aforementioned adjusting column 9, with external threads at both ends and a limiting protrusion ring 1201 on the connecting member 12. One end of the connecting member 12 is screwed to the housing of the motor 3, and the other end passes through the door reinforcement plate 102 and is screwed to the nut 10, with the limiting protrusion ring 1201 and the nut 10 respectively abutting against both sides of the door reinforcement plate 102.

[0073] Based on the overall description above, the door window lifting mechanism of this embodiment can adjust the position of the door window 5 in the width direction of the vehicle body by rotating the adjusting column 9 to change the position of the guide rail 2 in the width direction of the vehicle body. Additionally, by sliding the insert 401 along the length or height direction of the insertion hole 605, the position of the slider 6 in the length or height direction of the vehicle body can be adjusted, thereby adjusting the position of the door window 5 in the length or height direction of the vehicle body. This effectively solves the problem that the position of the door window 5 in existing car doors 1, especially frameless car doors 1, cannot be adjusted.

[0074] Example 2

[0075] This embodiment relates to a car door window lifting system, including the car door window lifting mechanism described in Embodiment 1, and also includes a drive unit that is connected to the slider 6 in a transmission manner, and the drive unit is fixed on the car door 1.

[0076] Among them, reference Figure 1 As shown, the driving unit in this embodiment is specifically a motor 3 connected to the slider 6 via a pull wire 7, and the connection relationship between the three can be found in the prior art.

[0077] The door window lifting system of this embodiment, by adopting the door window lifting mechanism described in Embodiment 1, can adjust the position of the door window 5 in the length, width and height directions of the vehicle body, thereby achieving better performance.

[0078] In addition, this embodiment also relates to a car door, which is equipped with the door window lifting system described above.

[0079] The car door of this embodiment, by adopting the door glass lifting system as described above, can realize the adjustment of the position of the door glass 5, which can improve the overall quality of the car door.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
