DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, the embodiments of the present disclosure will be described in detail. Examples of the embodiments are shown in the accompanying drawings, and in all the accompanying drawings, the same or similar reference numerals refer to the same or similar components or components having the same or similar functions.

[0022] The terms "first" and "second" are used merely for descriptive purposes and should not be construed as indicating or implying a relative importance or number of technical features indicated. Thus, a feature qualified by "first" or "second" can explicitly indicate or implicitly include at least one of such features. In the description of this disclosure, unless expressly specified otherwise, "plurality" means at least two, e.g., two or three.

[0023] Hereinafter, a vehicle door assembly 100 according to an embodiment of the present disclosure will be described with reference to FIGS.

[0024] 1 to 3, a vehicle door assembly 100 according to an embodiment of the present disclosure includes a vehicle door 1, an unlocking assembly 2, and a handle assembly 3. The unlocking assembly 2 is disposed on the vehicle door 1 so as to unlock the vehicle door 1. A handle groove 11 is provided on the vehicle door 1, and the handle assembly 3 is disposed on the handle groove 11. The handle assembly 3 includes a handle 31 and a first pivot shaft 32. The first pivot shaft 32 is pivotably disposed on the handle groove 11. The handle 31 is disposed on the first pivot shaft 32. The handle 31 has a retracted position and an unlocked position. When the handle 31 is in the retracted position, the handle 31 is placed in the opening of the handle groove 11 and does not protrude beyond the surface of the vehicle door 1. When the handle 31 is in the unlocked position, the handle 31 is placed in the handle groove 11, and the handle 31 contacts the unlocking assembly 2 to drive the unlocking assembly 2 to unlock the vehicle door 1 under the action of an external force.

[0025] Specifically, when the handle 31 is not in use, the handle 31 is in a retracted position, i.e., the handle 31 is in a hidden state, at which the handle 31 is flush with the outer sheet metal surface of the vehicle door 1. When the handle 31 needs to be used, the handle 31 is rotated at a certain angle toward the inside of the vehicle to expose the space of the handle groove 11. By pressing the handle 31, the handle 31 contacts the unlocking assembly 2, and thus the vehicle door 1 is opened by the unlocking assembly 2. After the unlocking is completed, the handle 31 returns from the unlocking position to the retracted position, at which the handle 31 is flush with the outer sheet metal surface of the vehicle door 1 and returns to the hidden state.

[0026] In the embodiment of the present disclosure, the handle 31 rotates toward the inside of the vehicle door 1 when in use. The handle 31 does not protrude beyond the surface of the vehicle door 1 even when in the unlocked position, and thus the handle 31 can be completely hidden. Such a structural design helps to reduce wind resistance and fuel consumption on the one hand, and the handle 31 is integrated with the shape of the vehicle door 1, thereby enhancing the texture of the vehicle door assembly 100 on the other hand.

[0027] Therefore, by rotating the handle 31 inward, it can be ensured that the handle 31 is always in a hidden state, which not only reduces wind resistance but also avoids the trouble of a hidden handle extending outward being unable to be opened in a sub-freezing environment.

[0028] Also, as shown in FIG. 5 and FIG. 6, the vehicle door assembly 100 further includes a power assembly 4, which is connected to the first pivot shaft 32 to drive the handle 31 to rotate between the retracted position and the unlocked position. Specifically, when the handle 31 is used, the power assembly 4 automatically rotates the handle 31 from the retracted position to the unlocked position, and then the user presses the handle 31 to drive the unlocking assembly 2 to unlock the vehicle door 1. After unlocking, the power assembly 4 returns the handle 31 from the unlocked state to the retracted position. This arrangement can realize the automatic rotating action of the handle 31, thereby improving the user experience and also avoiding the situation where the spring element pinches the hand and affects the user's action.

[0029] Besides, as shown in FIG. 6 , the power assembly 4 includes a drive member 5 and a transmission device 6, and the transmission device 6 is transmission-connected between the first pivot shaft 32 and the drive member 5. The drive member 5 drives the first pivot shaft 32 to rotate by the transmission device 6, and the first pivot shaft 32 rotates together with the handle 31, so that the handle 31 reciprocates between a retracted position and an unlocked position. Because the rotation angle of the handle 31 is relatively large, if the drive member 5 is directly connected to the first pivot shaft 32, the stroke of the drive member 5 is likely to be too long, and the required stroke space is relatively large, which is not conducive to the arrangement of the power assembly 4. Therefore, by providing the transmission member 61, the drive member 5 can be avoided to be directly connected to the first pivot shaft 32 for transmission, thereby reducing the stroke space occupied by the drive member 5 and facilitating the arrangement of the power assembly 4.

[0030] 6, the transmission device 6 includes a transmission member 61, a rocker arm 62, and a slider 63. The transmission member 61 is transmission-connected to the first pivot shaft 32, the slider 63 is transmission-connected to the driving member 5, a slide slot 631 is provided in the slider 63, the rocker arm 62 is connected to the transmission member 61, and one end of the rocker arm 62 is inserted into the slide slot 631. When the driving member 5 pushes the slider 63 to move back and forth, the inner wall of the slide slot 631 drives the rocker arm 62 to swing back and forth, and the rocker arm 62 drives the first pivot shaft 32 to rotate by the transmission member 61.

[0031] Specifically, according to the content of the above embodiment, when the handle needs to be used to unlock the vehicle door 1, the driving member 5 transmits power through the transmission device 6, thereby driving the handle 31 to rotate to the unlocked position toward the inside of the vehicle, and then the user presses the handle 31 to drive the unlocking assembly 2 to rotate, thereby opening the vehicle door 1 by the unlocking assembly 2. During this process, after the driving member 5 rotates the handle 31 to the unlocked position, the driving member 5 stops, but the handle 31 needs to continue to move downward under the pressure of the user to press the unlocking assembly 2 to rotate. Therefore, in order to realize the second rotation of the handle 31, the transmission device 6 needs to set a clearance space. By providing the slider 63 with a slide slot 631, and the length of the slide slot 631 being greater than the rotation circumference of the handle 31 during the second rotation, it is ensured that the handle 31 is smoothly driven to rotate the unlocking assembly 2.

[0032] In use, the telescopic rod of the driving member 5 extends and drives the slider 63 to move. At this time, the inner wall of the slide slot 631 adjacent to the driving member 5 pushes the rocker arm 62 to rotate forward, and the rocker arm 62 transmits power to the first pivot shaft 32 through the transmission member 61, thereby driving the handle 31 to rotate to the unlocking position. Subsequently, when the user needs to unlock the vehicle door 1, he or she presses the handle 31 hard, thereby driving the unlocking assembly 2 to rotate. At this time, the first pivot shaft 32 transmits the force to the transmission member 61, so that the rocker arm 62 continues to rotate forward, that is, the rocker arm 62 rotates independently away from the driving member 5.

[0033] Through the cooperation of the rocker arm 62 and the slider 63, the segmented movement characteristics of the handle 31 can be effectively realized, which not only has a simple structure and low function cost, but is also stable and less susceptible to damage, thereby improving the reliability of the transmission device 6.

[0034] In an embodiment of the present disclosure, as shown in Fig. 4 and Fig. 6, there are at least two transmission members 61, and the at least two transmission members 61 include a driving gear 611 and a driven gear 612. The diameter of the driving gear 611 is larger than the diameter of the driven gear 612. The driving gear 611 and the driven gear 612 are meshed for transmission. The driving gear 611 is disposed on the rocker arm 62, and the driven gear 612 is disposed on the first pivot shaft 32.

[0035] Specifically, by setting the gear transmission, the direction of power transmission of the driving member 5 can be realized, so that the rotation direction of the handle 31 is opposite to the moving direction of the slider 63 driven by the driving member 5, which facilitates the handle 31 to enter the second stage and drive the unlocking swing arm 21 to unlock the vehicle door 1. At the same time, by setting the driving gear 611 larger than the driven gear 612, the moving distance of the slider 63 can be enlarged, thereby making the transmission space occupied by the transmission device 6 smaller, and more other components can be put into the limited space of the vehicle door 1.

[0036] 6 and 7, in the embodiment of the present disclosure, the slider 63 further includes a mounting groove 632, and the driving member 5 is provided with a limiting plate 51, which is embedded in the mounting groove 632. Specifically, the slider 63 is a wear part and is prone to wear between the rocker arm 62 after long-term use, so a split connection between the slider 63 and the telescopic rod of the driving member 5 is adopted, which can facilitate the individual replacement of the slider 63 and reduce the use cost.

[0037] In an embodiment of the present disclosure, as shown in FIG. 6 , the unlocking assembly 2 also includes an unlocking swing arm 21, a second pivot axis 22, and an unlocking fastener 23, the second pivot axis 22 is respectively connected to the unlocking swing arm 21 and the unlocking fastener 23, and the unlocking swing arm 21 rotates around the second pivot axis 22 under the action of the handle 31, driving the unlocking fastener 23 to rotate and unlock the vehicle door 1.

[0038] Specifically, when the first pivot shaft 32 is disposed under the handle groove 11, the second pivot shaft 22 is disposed on one side of the first pivot shaft 32. At this time, the unlocking swing arm 21 is disposed under the unlocking position and is in close contact with the handle 31, so that it is convenient for the user to press the handle 31 to drive the unlocking swing arm 21 to rotate. The unlocking catch 23 also rotates under the driving of the second pivot shaft 22, so that the lock core of the vehicle door 1 can be disengaged from the door bolt, thereby unlocking the vehicle door 1. Such a setting makes it easy to realize the link mechanism between the unlocking swing arm 21 and the handle 31, and avoids the user from directly contacting the unlocking swing arm 21 with his hands, which is favorable for the arrangement of the handle assembly 3 and the unlocking assembly 2.

[0039] In addition, as shown in FIG. 3 , the vehicle door assembly 100 further includes a shell 7 and a fixed plate 71, the handle groove 11 is formed between the shell 7 and the vehicle door 1, the fixed plate 71 is connected to the shell 7, and the first pivot shaft 32 and the second pivot shaft 22 are both connected to the fixed plate 71.

[0040] Specifically, the shell 7 is disposed on the vehicle door 1, and the periphery of the shell 7 is connected to the inner wall of the vehicle door 1. The setting of the shell 7 can protect the rotation of the handle 31 and the unlocking swing arm 21 in the handle groove 11, thereby preventing other components of the vehicle door 1 from interfering with the rotation of the handle 31 and the unlocking swing arm 21 and affecting the normal unlocking function of the vehicle door 1. At the same time, the shell 7 can also function as a fixed seat, that is, a fixed plate 71 is disposed on the shell 7 to facilitate the first pivot shaft 32 and the second pivot shaft 22 to be assembled to the fixed plate 71, thereby simplifying the assembly structure and improving the integration of the vehicle door assembly 100.

[0041] In an embodiment of the present disclosure, as shown in Fig. 5 and Fig. 8, the vehicle door assembly 100 further includes a lock assembly 8, which includes a lock block 81 and a puller 82, and the lock block 81 is connected to the puller 82. When the handle 31 is in a retracted position, the lock block 81 extends to the rear of the handle 31 to lock the rotation of the handle 31. Specifically, when the vehicle door 1 is in a closed state, the rotation of the handle 31 is locked by the lock block 81, thereby playing an anti-theft role and preventing an external force from violently pushing the handle 31 to rotate it inwardly to open the vehicle door 1.

[0042] A vehicle according to an embodiment of the present disclosure includes the above-described vehicle door assembly 100. Specifically, a vehicle using the above-described vehicle door assembly 100 can improve the overall texture and operational comfort, which helps to enhance the market competitiveness of the vehicle.
