[0002] In order to achieve the aesthetic design of vehicle doors, many existing vehicles have begun to use hidden door handles. The obvious advantage of hidden door handles is that it makes people feel that the vehicle model is more high-end in appearance, and because the door handles are in a retracted and hidden state during the driving of the vehicle, they can also reduce the wind resistance of the vehicle.

[0003] Specifically, a hidden door handle is usually designed with a movable structure in the inner cavity of the door, and the movable structure can drive the door handle to extend or retract. That is, when the door handle is needed to open the door, the movable structure can drive the door handle to extend. When the door handle is not needed, the movable structure drives the door handle to retract to be flush with the outer surface of the door or lower than the outer surface of the door to hide the door handle. At present, the movable structure for realizing the extension and retraction of the door handle is often driven by a connecting rod assembly and a drive motor. The specific connecting rod assembly includes a plurality of connecting rods hinged to each other, one of which is connected to the drive motor, and another of which is connected to the door handle. The drive motor drives the entire connecting rod assembly to move, thereby driving the door handle to retract.

[0004] However, due to the low transmission efficiency of the connecting rod assembly, the response of the connecting rod assembly to retract the door handle is slow, and thus the user's usage needs cannot be met. Utility Model Content

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] Reference Figure 1 As shown, this embodiment provides a door handle driving structure, including a driving member 1, a gear transmission assembly 2 and a rack transmission assembly 3.

[0038] The rack transmission assembly 3, the driving member 1 and the gear transmission assembly 2 are all arranged in the inner cavity of the vehicle door and the rack transmission assembly 3 can move along the width direction of the door. The rack transmission assembly 3 is connected to the door handle 4 of the vehicle and cooperates with the gear transmission assembly 2 in transmission.

[0039] The driving member 1 cooperates with the gear transmission assembly 2 to drive the gear transmission assembly 2 to rotate, so as to drive the rack transmission assembly 3 to move and link the door handle 4 to extend and retract.

[0040] When implementing it, refer to Figure 1 As shown, the rack transmission assembly 3 is arranged in the inner cavity of the vehicle door and connected to the vehicle door handle 4. By matching the driving member 1 with the gear transmission assembly 2, and the gear transmission assembly 2 with the rack transmission assembly 3, when the door handle 4 needs to be driven to be extended or retracted, the driving member 1 drives the gear transmission assembly 2 to rotate to drive the rack transmission assembly 3 to move along the width direction of the door, and then the door handle 4 is linked to move to achieve extension and retraction. The whole structure is simple and the transmission efficiency is high, so that the extension and retraction response of the door handle 4 is faster.

[0041] For example, the width direction of the door can refer to Figure 1 The y1-y2 direction is shown. For example, the extension direction of the door handle 4 is set to the y2-y1 direction, and the retraction direction of the door handle 4 is set to the y1-y2 direction. When the door handle 4 needs to be extended to open or close the door through the door handle 4, the driving member 1 can drive the gear transmission assembly 2 to rotate in the first direction, thereby driving the rack transmission assembly 3 to move in the y2-y1 direction so as to extend out of the door, so that the user can hold the door handle 4 to open or close the door. When the door handle 4 needs to be retracted to achieve the hiding operation of the door handle 4, the driving member 1 can drive the gear transmission assembly 2 to rotate in the second direction, thereby driving the rack transmission assembly 3 to move in the y1-y2 direction so as to retract into the door.

[0042] It should be noted that the first direction and the second direction are opposite directions. For example, when the first direction is clockwise, the second direction is counterclockwise. Or, when the first direction is counterclockwise, the second direction is clockwise.

[0043] Exemplarily, the driving component 1 may be, for example, a driving motor or a driving cylinder.

[0044] Exemplarily, the connection between the rack transmission assembly 3 and the door handle 4 may be a snap-on connection or a connection via fasteners such as bolts.

[0045] The door handle driving structure of this embodiment drives the gear transmission assembly 2 to rotate through the driving member 1, and then drives the rack transmission assembly 3 to move. The rack transmission assembly 3 moves the door handle 4 connected thereto to move along the width direction of the door to achieve retraction. Compared with the method of using a connecting rod assembly to achieve the extension and retraction of the door handle 4, the transmission ratio of the gear transmission assembly 2 and the rack transmission assembly 3 is more accurate, so the transmission efficiency is higher, so that the retraction operation of the door handle 4 responds faster, and thus can meet the user's use needs.

[0046] Reference Figure 1 As shown, in some embodiments, the gear transmission assembly 2 includes at least a first transmission gear 21 and a second transmission gear 22 that are meshed with each other, and the rack transmission assembly 3 includes at least a first transmission rack 31 and a second transmission rack 32, and the first transmission rack 31 and the second transmission rack 32 are both connected to the door handle 4.

[0047] Any one of the first transmission gear 21 and the second transmission gear 22 is in transmission cooperation with the driving member 1. One of the first transmission gear 21 and the second transmission gear 22 is in transmission cooperation with the first transmission rack 31, and the other of the first transmission gear 21 and the second transmission gear 22 is in transmission cooperation with the second transmission rack 32.

[0048] In specific implementation, in order to make the movement of the door handle 4 more stable and smooth, the gear transmission assembly 2 can be provided to include a first transmission gear 21 and a second transmission gear 22 meshing with each other. At this time, the rack transmission assembly 3 can include a first transmission rack 31 and a second transmission rack 32, and the driving member 1 is in transmission cooperation with one of the first transmission gear 21 and the second transmission gear 22, and the first transmission rack 31 and the second transmission rack 32 are respectively matched with the first transmission gear 21 and the second transmission gear 22 one by one, so that when the first transmission gear 21 and the second transmission gear 22 can be driven to rotate by the driving member 1, the first transmission rack 31 and the second transmission rack 32 are respectively linked to move synchronously in the same direction, and then the door handle 4 is driven by the first transmission rack 31 and the second transmission rack 32 to move smoothly along the width direction of the door, so as to prevent the door handle 4 from being skewed or offset when moving and affecting its normal use.

[0049] Reference Figure 1 As shown, in some embodiments, the first transmission rack 31 and the second transmission rack 32 are spaced apart and arranged in parallel along a direction perpendicular to the width of the vehicle door, and the first transmission rack 31 and the second transmission rack 32 both extend along the width of the vehicle door.

[0050] Specifically, the first transmission rack 31 and the second transmission rack 32 themselves are along the following Figure 1 The first transmission rack 31 and the second transmission rack 32 extend in the direction of y1-y2 as shown. Figure 1As shown, the first transmission rack 31 and the second transmission rack 32 are arranged in parallel with each other in the x direction, so that when moving, they can drive the door handle 4 to move smoothly and synchronously along the direction of y1 - y2 .

[0051] Reference Figure 1 As shown, in some embodiments, the first transmission gear 21 and the second transmission gear 22 are both located between the first transmission rack 31 and the second transmission rack 32, and the line connecting the central axis of the first transmission gear 21 and the central axis of the second transmission gear 22 is perpendicular to the width direction of the vehicle door.

[0052] Specifically, by arranging the first transmission gear 21 and the second transmission gear 22 between the first transmission rack 31 and the second transmission rack 32, the space between the first transmission rack 31 and the second transmission rack 32 can be effectively utilized to accommodate the first transmission gear 21 and the second transmission gear 22, which is conducive to achieving the compactness of the entire door handle drive structure. In addition, by arranging the connecting line of the central axis of the first transmission gear 21 and the central axis of the second transmission gear 22 to be perpendicular to the width direction of the door, it is more conducive to achieving efficient transmission coordination between the first transmission gear 21 and the second transmission gear 22 and achieving synchronous and smooth movement of the first transmission rack 31 and the second transmission rack 32 respectively coordinated with them.

[0053] Reference Figure 1 As shown, in some embodiments, the door handle drive structure also includes a base 5, which is used to be set in the inner cavity of the vehicle door, and the driving member 1 is connected to the base 5; a sliding support 6 is arranged between the base 5 and the rack transmission assembly 3, and a first sliding part is arranged on the sliding support 6, and a second sliding part is arranged on the rack transmission assembly 3, and the first sliding part and the second sliding part are slidably matched.

[0054] In specific implementation, in order to facilitate the assembly of the driving member 1 and the rack transmission assembly 3 in the inner cavity of the vehicle door, a base 5 can be set in the inner cavity of the vehicle door, the driving member 1 can be fixed on the base 5, and a sliding support 6 is set between the rack transmission assembly 3 and the base 5, so as to facilitate the sliding of the rack transmission assembly 3 relative to the base 5 along the width direction of the vehicle door.

[0055] For example, the base 5 and the sliding support 6 may be fixed by clamping or screwing. The driving member 1 and the base 5 may be fixed by clamping or screwing. Further, a first sliding portion may be provided on the sliding support 6, and a second sliding portion may be provided on the rack transmission assembly 3, so that the rack transmission assembly 3 can slide smoothly along the width direction of the door through the cooperation of the first sliding portion and the second sliding portion.

[0056] Reference Figure 1As shown, in some embodiments, one of the first sliding portion and the second sliding portion is a sliding groove 61 that slides along the width direction of the vehicle door, and the other of the first sliding portion and the second sliding portion is a sliding block 33 that can slide along the sliding groove 61.

[0057] For example, a sliding groove 61 may be provided on the sliding support 6, and the sliding groove 61 may be provided along the sliding support 6. Figure 1 As shown, the rack transmission assembly 3 is provided with a sliding block 33 that can slide along the sliding groove 61, so that the movement of the rack transmission assembly 3 can be reliably guided by the sliding cooperation between the sliding block 33 and the sliding groove 61. A groove can be formed by recessing one side surface of the sliding support 6, and the groove extends along the y1-y2 direction to serve as the sliding groove 61. The sliding block 33 is connected to the side of the rack transmission assembly 3 facing the sliding support 6, and the sliding block 33 is inserted into the groove, so that the sliding block 33 is slidably connected with the sliding groove 61, so that when the rack transmission assembly 3 moves relative to the sliding support 6, the sliding block 33 is driven to move in the sliding groove 61.

[0058] Alternatively, a plate body connected to the rack transmission assembly 3 may be selected, and a groove extending along the y1-y2 direction is provided on one side of the plate body facing the sliding support 6 as a sliding groove 61, and a sliding block 33 is provided on the side of the sliding support 6 facing the rack transmission assembly 3, and the sliding block 33 is inserted into the groove on the plate body so that the sliding block 33 is slidably connected with the sliding groove 61, and when the rack transmission assembly 3 moves relative to the sliding support 6, it drives the plate body provided with the sliding groove 61 to move relative to the sliding support 6, so that the sliding block 33 slides in the sliding groove 61, so that the sliding block 33 and the sliding groove 61 are slidably matched to guide the movement of the rack transmission assembly 3.

[0059] Reference Figures 1 to 5 As shown, this embodiment also provides a door handle assembly, including a door handle 4 and a door handle driving structure. The door is provided with a mounting opening for the door handle 4 to be retracted and extended, and the mounting opening is connected to the inner cavity of the door.

[0060] The specific structure and implementation principle of the door handle drive structure in this embodiment are the same as those of the door handle drive structure provided in the above embodiment, and can bring the same or similar technical effects, which will not be described one by one here, and the details can be referred to the description of the above embodiment.

[0061] Reference Figure 4 As shown, in some embodiments, a hydrophobic layer is provided on the outer wall of the door handle 4. By providing the hydrophobic layer on the outer wall of the door handle 4, the hydrophobic layer can effectively reduce the deposition of rainwater on the door handle 4, and then can effectively reduce the condensation and ice on the surface of the door handle 4, so as to avoid affecting the normal extension and retraction operation of the door handle 4.

[0062] Specifically, a hydrophobic coating, such as a coating made of an organic-inorganic hybrid material or a fluorine / silicon material, may be applied to the outer wall of the door handle 4 so that the hydrophobic coating forms a hydrophobic layer on the outer wall of the door handle 4, thereby reducing the adhesion of ice on the door handle 4 in a low temperature environment.

[0063] Reference Figure 4 As shown, in some embodiments, a hydrophobic layer may be provided only on the outer wall of the door handle 4, or a heating module 7 may be provided only on the side of the door handle 4 facing the inner cavity of the door, and the door handle 4 is heated by the heating module 7 to eliminate frost deposited on the door handle 4, or a hydrophobic layer may be provided on the outer wall of the door handle 4 and a heating module 7 may be provided on the side of the door handle 4 facing the inner cavity of the door.

[0064] Exemplarily, at least one heating module 7 can be provided on the door handle 4, for example, two or more heating modules 7 can be provided. When two or more heating modules 7 are provided, the heating modules 7 can use the same structure or different structures. For example, the heating module 7 can use a PTC (Positive Temperature Coefficient) heating module 7 or a TEC (Thermoelectric Cooler) temperature control module. Among them, the PTC heating module 7 is also called a PTC heating element, which is composed of a PTC ceramic heating element and an aluminum tube. This type of PTC heater has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power-saving electric heater. The outstanding feature lies in the safety performance. In any application situation, the surface "redness" phenomenon such as electric heating tube heaters will not occur, thereby causing safety hazards such as burns and fires. The TEC temperature control module has the characteristics of high temperature control stability, high energy efficiency, compact size, and zero electromagnetic interference.

[0065] Exemplarily, the heating module 7 can be adhered to the door handle 4 or can also be snapped onto the door handle 4 .

[0066] Reference Figures 2 to 5 As shown, in some embodiments, the door handle assembly also includes a connecting beam 8, which is connected to the side of the door handle 4 facing the inner cavity of the door, and the connecting beam 8 is connected to the rack transmission assembly 3, so that when the rack transmission assembly 3 moves, the door handle 4 can be driven to move by the connecting beam 8 to realize the telescopic operation of the door handle 4.

[0067] For example, the connecting crossbeam 8 and the rack transmission assembly 3 can be fixed by bonding, clamping or screwing.

[0068] Reference Figures 3 to 5As shown, in some embodiments, at least two first connecting portions 41 are provided on one side of the door handle 4 close to the connecting beam 8, and at least two second connecting portions 81 are provided on the connecting beam 8. The second connecting portions 81 correspond to the first connecting portions 41 one by one to connect the door handle 4 and the connecting beam 8 together.

[0069] The connecting crossbeam 8 is provided with a slide groove 82 extending in a direction perpendicular to the width of the vehicle door. A sliding member 83 that can slide along the slide groove 82 is provided in the slide groove 82 , wherein one of the second connecting portions 81 is provided on the sliding member 83 .

[0070] In a specific implementation, the first connection portion 41 and the second connection portion 81 can both be connection holes, and a connection pin is provided in the connection hole to achieve the fixing of the door handle 4 and the connection beam 8. Alternatively, one of the first connection portion 41 and the second connection portion 81 can be a connection hole, and the other can be a connection shaft, and the connection shaft is inserted into the connection hole, so as to achieve the fixing of the door handle 4 and the connection beam 8.

[0071] Furthermore, the connecting beam 8 is provided with Figure 5 The slide groove 82 shown extends in the x direction, and a sliding member 83 is arranged in the slide groove 82, wherein a second connecting portion 81 is arranged on the sliding member 83, and by changing the position of the sliding member 83 in the slide groove 82, it can adapt to the connection between the door handles 4 of different sizes and the connecting beam 8.

[0072] For example, when the size of the door handle 4 is small, the sliding member 83 can be moved in the slide groove 82 toward the direction close to the other second connection portion 81, so that the distance between the two adjacent second connection portions 81 along the x direction is shorter. For example, when the size of the door handle 4 is large, the sliding member 83 can be moved in the slide groove 82 toward the direction away from the other second connection portion 81, so that the distance between the two adjacent second connection portions 81 along the x direction is longer.

[0073] Exemplarily, the slide groove 82 may be a rectangular slide groove 82 with a rectangular cross section or a dovetail-shaped slide groove 82 with a dovetail-shaped cross section. In addition, the sliding member 83 may be a slider or a pulley.

[0074] In addition, in order to facilitate sliding the sliding member 83 into the sliding groove 82 , the sliding groove 82 can be configured with one end extending to the end of the connecting beam 8 .

[0075] In some embodiments, in order to allow the sliding member 83 to slide in the slide groove 82 and not slide easily after sliding to the desired position, a clearance fit between the sliding member 83 and the slide groove 82 can be set, so as not to affect the sliding of the sliding member 83 in the slide groove 82 and to make the fitting clearance between the two smaller, so that the sliding member 83 will not slide easily after sliding to the desired position.

[0076] Alternatively, in other implementations, a locking member may also be provided in the sliding member 83, and the locking member may be moved relative to the sliding member 83 toward the bottom wall of the slide groove 82 until it abuts against the bottom wall of the slide groove 82, and may be moved toward the bottom wall away from the slide groove 82 until it releases the abutment against the bottom wall of the slide groove 82.

[0077] That is, when the sliding member 83 needs to slide in the slide slot 82, the locking member can be moved in a direction away from the bottom wall of the slide slot 82 until the abutment with the bottom wall of the slide slot 82 is released, and the sliding member 83 can slide smoothly in the slide slot 82. When the sliding member 83 slides to a desired position, the locking member is moved in a direction close to the bottom wall of the slide slot 82 until it abuts against the bottom wall of the slide slot 82, and the sliding member 83 cannot continue to slide, so that the sliding member 83 is reliably fixed at this position, so as to prevent the position of the door handle 4 from being unstable and unreliable.

[0078] Exemplarily, the locking member may be a bolt, in which case a threaded hole may be provided on the sliding member 83, and the bolt fits into the threaded hole. The bolt can be loosened or tightened to achieve or release the abutment with the bottom wall of the slide groove 82.

[0079] Alternatively, the locking member may be a pin, in which case a through hole may be provided on the sliding member 83, and the pin is inserted into the hole, so that the pin can be moved to engage with or release the bottom wall of the slide groove 82. In this case, a buckle that is locked with the pin can be provided on the sliding member 83, and the pin can be fixed by the buckle when it moves to a desired position.
