Abstract
Description
Technical Field
[0001] The utility model relates to the field of vehicles, in particular to a Dutch Reach door handle structure. Background Art
[0002] When a vehicle door is opened, if there are pedestrians or vehicles passing by on the side where the door is opened, a collision accident is likely to occur. To avoid such accidents, one method is to install a door opening warning system on the vehicle. However, due to cost and other reasons, the door opening warning system has not been widely applied. Another method is to adopt the Dutch Reach method, which advocates opening the door with the hand farther away from the door. That is, when the driver or passenger opens the left door, they need to use their right hand, and when opening the right door, they need to use their left hand.
[0003] The Dutch Reach method has two major advantages. First, when the driver or passenger opens the door, they need to turn sideways, which can more conveniently see pedestrians or vehicles behind the vehicle on the side, so as to avoid them in time. Second, since the driver or passenger opens the door with the farther hand, the opening angle of the door is smaller, thus leaving more dodging space and time for pedestrians or vehicles behind the vehicle, effectively avoiding collision accidents.
[0004] Currently, the door opening device adopting the Dutch Reach method usually controls an elastic limiting mechanism by adding a thumb push block / button to control whether the handle can be pulled. At the same time, the hand closer to the door cannot operate the handle and the thumb push block / button simultaneously, so as to force the driver or passenger to turn around and use the farther hand to operate the handle and the thumb push block / button, thus achieving the purpose of Dutch Reach. For example, the door opening device disclosed in the Chinese utility model patent CN210622537U. However, this kind of door opening device does not conform to the habit of the driver or passenger to pull the handle first, and it is easy to reduce the door opening experience of the driver or passenger. In addition, when the driver or passenger is not familiar with such a door opening device, they may directly pull the handle and over-pull the handle, which is likely to cause the handle to break.
[0005] The information disclosed in the background part of the present utility model is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.

[0045] It should be understood that the drawings are not necessarily drawn to scale and instead present simplified representations of various features to illustrate the basic principles of the present invention. The specific design features disclosed in the present invention (including, for example, specific dimensions, directions, positions, and shapes) will be determined in part by the specific environment in which it is to be applied and used.
[0046] In these figures, throughout the several views of the drawings, the same reference numerals denote the same or equivalent parts of the present invention. Detailed Description of the Invention
[0047] The following will refer in detail to the various embodiments of the present invention, examples of which are shown in the drawings and described below. Although the present invention will be described in conjunction with the exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternative forms, modifications, equivalent forms, and other embodiments that may be included within the spirit of the present invention and the scope defined by the appended claims.
[0048] The following will be combined with Figures 1 to 8C to describe the Dutch door handle structure of the present invention.
[0049] Figure 1 is an overall structural schematic diagram of the Dutch door handle structure according to an exemplary embodiment of the present invention. Figure 2 is another overall structural schematic diagram of the Dutch door handle structure according to an exemplary embodiment of the present invention. Figure 3 is a cross-sectional schematic diagram taken along the Figure 2 A - A line in
[0050] First, for convenience of description, in the present invention, "front" when describing the relative position of the specific structure refers to the forward direction of the vehicle, and "rear" refers to the backward direction of the vehicle.
[0051] As Figures 1 to 3 shown, the Dutch door handle structure of the present invention includes: a base 100, a handle 200, a button 300, and a locking assembly 400.
[0052] The base 100 is disposed on the inner wall of the vehicle door and serves as a part of the interior trim of the vehicle door. In cooperation with Figure 1 and Figure 4 As shown, the base 100 is provided with a receiving portion 110 and a shaft 120 located in the receiving portion 110, and the base 100 has an opening 130. Among them, the structure of the base 100 shown in the drawings provided by the present utility model is only a partial structure, and it further includes other structures not shown in the drawings, for example, a support structure for supporting the shaft 120.
[0053] The handle 200 is rotatably connected to the base 100 through the shaft 120. The button 300 is disposed in the opening 130 and can be exposed in the passenger space of the driver and passengers through the opening 130, and the button 300 is located at a rear position of the vehicle relative to the handle 200. The locking assembly 400 is disposed between the button 300 and the rear end portion of the handle 200, and when the button 300 is pressed after the handle 200 is rotated, the locking assembly 400 pulls the cable 600 of the vehicle door lock to open the vehicle door.
[0054] That is to say, the button 300 is disposed at a rear position of the vehicle relative to the handle 200, and the vehicle door can only be opened by pressing the button 300 after the handle 200 is rotated. This makes it impossible for the driver and passengers to pull the handle 200 and press the button 300 with one hand closer to the vehicle door, thus forcing the driver and passengers to use the hand farther from the vehicle door to pull the handle 200 and / or press the button 300, so as to achieve the purpose of Dutch-style door opening, thereby facilitating the driver and passengers to better observe the situation behind the vehicle and avoiding collision accidents.
[0055] Here, the cable 600 of the vehicle door lock is a device commonly used in the prior art for connecting the vehicle door lock and the door opening handle structure. When the cable 600 is pulled, the door lock is opened, so that the vehicle door can be opened, which will not be elaborated herein.
[0056] Specifically, in cooperation with Figure 1 and Figure 4 As shown, a recessed portion 140 is provided at the front portion of the base 100, and a through hole 150 is provided between the recessed portion 140 and the receiving portion 110. The middle portion of the handle 200 is connected to the base 100 through the shaft 120, and the rear end portion of the handle 200 is located in the receiving portion 110, and the front end portion of the handle 200 passes through the through hole 150 and is located in the recessed portion 140. Here, the receiving portion 110 is located inside the interior trim of the vehicle door, and the recessed portion 140 is located outside the interior trim of the vehicle door (the passenger space of the driver and passengers), so that the driver and passengers can rotate the handle 200 by operating the front end portion of the handle 200.
[0057] According to an exemplary embodiment of the present utility model, in cooperation with Figure 5 and Figure 6As shown, the base 100 is provided with an extension plate 160 extending towards the accommodating portion 110 at a position corresponding to the opening 130, so as to define a limiting space 170. The locking assembly 400 includes a slider 410. The slider 410 is disposed in the limiting space 170 corresponding to the button 300 and can slide along the extension plate 160 in the limiting space 170. Further, in this embodiment, the rear end portion of the handle 200 is provided with a first inclined surface 210 facing the button 300. The slider 410 is in an "L" shape (as Figure 8A shown), and the first end of the slider 410 is formed into a semi-circular gear portion 411, and the second end of the slider 410 is connected to the cable 600 of the vehicle door lock. A second inclined surface 412 is formed at the bent portion of the "L" shaped slider 410. Among them, when the button 300 is pressed after the handle 200 is rotated, the slider 410 can slide along the extension plate 160 in the limiting space 170 under the pressing force of the button 300, and rotate when the second inclined surface 412 contacts the first inclined surface 210, so that the second inclined surface 412 can form a surface contact with the first inclined surface 210, thereby pulling the cable 600 of the vehicle door lock to open the vehicle door.
[0058] Furthermore, in cooperation with Figure 6 , Figure 7 and Figure 8A shown, the bottom surface of the button 300 facing the accommodating portion 110 is provided with teeth 310, and the teeth provided on the end surface of the gear portion 411 are engaged with the teeth 310 provided on the bottom surface of the button. Thus, when the button 300 is pressed and the second inclined surface 412 of the slider 410 contacts the first inclined surface 210 of the handle 200, the slider 410 can rotate more stably, so that the second inclined surface 412 can form a surface contact with the first inclined surface 210.
[0059] Furthermore, in cooperation with Figure 5 , Figure 6 and Figure 8A shown, the cable 600 includes a cable body 610 and a clamping member 620 provided at the end of the cable body 610. The second end of the slider 410 is provided with a clamping groove 413 corresponding to the clamping member 620 and a first avoidance groove 414 for avoiding the cable body 610. The rear end portion of the handle 200 is provided with a second avoidance groove 220 for avoiding the cable body 610. Among them, the clamping member 620 can be stably clamped in the clamping groove 413 and can rotate in the clamping groove 413. The cable body 610 can slide and rotate relative to the slider 410 in the first avoidance groove 414 (when the slider 410 slides and rotates) to avoid interference with the slider 410, and the cable body 610 can rotate relative to the handle 200 in the second avoidance groove 220 (when the handle 200 rotates) to avoid interference with the handle 200, thereby being beneficial to improving the stability and durability of the present utility model.
[0060] According to an exemplary embodiment of the present utility model, as Figure 3 , Figures 8A to 8C shown, the locking assembly 400 further includes a first elastic member 420. One end of the first elastic member 420 is disposed on the base 100, the other end of the first elastic member 420 is disposed on the slider 420, and the first elastic member 420 can provide an elastic force for the reset of the slider 410 after the slider 410 moves. Specifically, in conjunction with Figure 4 and Figure 6 shown, the base 100 is provided with a first mounting groove 180 at a rear position, and a connection hole 415 is provided in the middle of the slider 410. The first elastic member 420 is configured as a torsion spring, and one end of the first elastic member 420 is installed in the first mounting groove 180, and the other end of the first elastic member 420 is connected to the connection hole 415. Wherein, when the button 300 is not pressed, the first elastic member 420 can be set to a natural elongation state. When the button 300 is pressed, the slider 410 slides along the extension plate 160 in the limiting space 170 under the action of the pressing force of the button 300, and rotates when the second inclined surface 412 contacts the first inclined surface 210, which causes the first elastic member 420 to be twisted to generate an elastic restoring force to provide an elastic force for the reset of the slider 410.
[0061] According to an exemplary embodiment of the present utility model, as Figure 1 and Figure 3 shown, the Dutch door handle structure of the present utility model further includes a second elastic member 500. One end of the second elastic member 500 is disposed on the handle 200, the other end of the second elastic member 500 is disposed on the base 100, and the second elastic member 500 can provide an elastic force for the reset of the handle after the handle 200 rotates. Specifically, in conjunction with Figures 3 to 5 shown, the handle 200 is provided with a second mounting groove 230 around the shaft 120, and the base 100 is provided with an abutting portion 190. The second elastic member 500 is configured as a torsion spring, and one end of the second elastic member 500 is installed in the second mounting groove 230, and the other end of the second elastic member 500 abuts against the abutting portion 190. Wherein, when the handle 200 is not rotated, the second elastic member 500 can be set to a natural elongation state. When the handle 200 is rotated, the second elastic member 500 is twisted due to the rotation of the handle 200 to generate an elastic restoring force to provide an elastic force for the reset of the handle 200.
[0062] Wherein, the first elastic member 420 and the second elastic member 500 described above are both configured as torsion springs, but it should be clear that the types of the first elastic member 420 and the second elastic member 500 are not limited thereto, and they can be any form in the prior art as long as the above functions can be achieved.
[0063] According to an exemplary embodiment of the present utility model, in cooperation with Figure 4 As shown, the extension plate 160 is provided with a limiting portion 161 corresponding to the button 300. The limiting portion 161 is provided as a stepped structure formed by bending the extension plate 160 inwardly into the limiting space 170. The function of the limiting portion 161 is to prevent the button 300 from being pressed excessively.
[0064] Figures 8A to 8C FIG. is a schematic diagram of the operation process of the Dutch-style door opening handle structure of the present utility model during the opening of the door. Among them, Figure 8A is obtained along Figure 2 the B-B line in
[0065] Next, with reference to the accompanying drawings, the operation process of the Dutch-style door opening handle structure of the present utility model will be described.
[0066] When the door is closed, as Figure 8A shown, the handle 200 is not rotated and the button 300 is not pressed. At this time, the handle 200, the button 300 and the slider 410 are all in their initial positions, and the first elastic member 420 and the second elastic member 500 are both in a natural elongation state.
[0067] When the door is opened, first, in cooperation with Figure 8B shown, the driver or passenger can use one hand away from the door to pull the front end of the handle 200, so that the handle 200 rotates in the rotation direction T1 ( Figure 8B the counterclockwise direction in
[0068] Then, in cooperation with Figure 8C shown, the driver or passenger can use the thumb of one hand away from the door to press the button 300. The slider 410 slides in the limiting space 170 from the initial position along the extension plate 160 in the sliding direction S1 under the acting force of the pressing force of the button 300, and rotates in the rotation direction T1 ( Figure 8C the counterclockwise direction in
[0069] When the door is opened, the driver or passenger can release the button 300 and the handle 200 at the same time. Under the elastic restoring forces of the first elastic member 420 and the second elastic member 500, the handle 200, the button 300 and the slider 410 return to Figure 8A the initial positions shown in
[0070] The Dutch-style door opening handle structure of the present utility model sets the button relative to the handle at a position closer to the rear of the vehicle. During the process of opening the door, the driver or passenger needs to pull the front end of the handle to rotate the handle, and then cooperate with the button and the slider to open the door. This makes it impossible for the driver or passenger to use one hand closer to the door to both pull the handle and press the button, thus forcing the driver or passenger to use the hand farther from the door to pull the handle and / or press the button, achieving the purpose of Dutch-style door opening. The Dutch-style door opening handle structure of the present utility model can not only effectively avoid the possible collision accidents when the door is opened, but also conforms to the habit of the driver or passenger to pull the handle first, ensuring the door opening experience of the driver or passenger while avoiding the situation that the handle breaks due to the driver or passenger directly pulling the handle too hard because they are not familiar with the structure.
[0071] In addition, the Dutch-style door opening handle structure of the present utility model has the characteristics of simple structure, low cost and high adaptability, and has more advantages in market competition.
