Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sunshade equipment for vehicles, and in particular to a supporting mechanism, a sunshade assembly and a vehicle. BACKGROUND

[0002] A sunshade curtain is a commonly used automobile accessory, which is usually installed in cooperation with a front windshield, a sunroof, etc. It can effectively solve the problem of high temperature and strong light in summer, and improve the driving comfort. The sunshade curtain is made of high-quality sunshade fabric, which can effectively block direct sunlight and reduce the temperature rise in the vehicle, thereby reducing the burden on the air conditioner and improving fuel economy. In addition, the sunshade curtain can also protect the interior of the vehicle, prevent ultraviolet damage, and prolong the service life of components such as seats and instrument panels. Furthermore, the sunshade curtain can also improve privacy protection, avoid external peeping, and reduce strong light interference during driving, thereby improving safety. In summary, the front sunshade curtain is a simple and practical accessory that can effectively improve the driving experience of the vehicle owner and the protection of the interior of the vehicle.

[0003] In the conventional technology, the sunshade curtain is mainly composed of a power mechanism, an extension mechanism and a curtain cloth. The power mechanism is connected with the extension mechanism, and the curtain cloth is installed on the extension mechanism. The extension mechanism is driven to extend or retract by the power mechanism, so as to drive the curtain cloth to unfold or retract. However, the existing extension mechanism is generally a fork arm structure. When the fork arms are crossed and stacked, the contact area is large, which not only easily produces noise and affects the use experience, but also easily causes mutual interference between the fork arms, thereby causing deformation and affecting the service life. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a supporting mechanism, a sunshade assembly and a vehicle in view of the problems of noise affecting the use experience and interference deformation reducing the service life.

[0005] In a first aspect of the present application, a supporting mechanism is provided, which comprises:

[0006] a first fork arm comprising a first arm body and a first mounting body connected with each other, the first mounting body being provided with a receiving recess; and

[0007] a second fork arm comprising a second arm body and a second mounting body connected with each other, the second mounting body being rotatably arranged in the receiving recess, so that the second arm body and the first arm body can be relatively unfolded or folded.

[0008] When the first arm body and the first arm body are folded, the second arm body and the first arm body are arranged in a stacked manner along a first direction of the supporting mechanism.

[0009] The support mechanism of the scheme is applied to a sunshade assembly, so as to drive the curtain fabric to be unfolded to shield the glass or to be retracted to expose the glass. Specifically, the first fork arm is designed to be connected with the first arm body and the first mounting body, and the first mounting body is provided with a receiving recess. Meanwhile, the second fork arm is designed to be connected with the second arm body and the second mounting body. After the second mounting body is rotatably mounted in the receiving recess, the first fork arm and the second fork arm have the freedom of relative rotation and can be relatively unfolded or retracted, so that the support mechanism has the ability to drive the curtain fabric to be unfolded or retracted. Moreover, since the second mounting body is arranged in the receiving recess, only the first mounting body and the second mounting body form the cross-stacking effect, which provides the necessary support positioning when the first fork arm and the second fork arm are relatively rotated. However, the first arm body and the second arm body are cross-stacked, so that the first arm body and the second arm body are arranged in the first direction of the support mechanism. At this time, there is no large-area stacking between the first arm body and the second arm body, so that noise is avoided when being relatively rotated. Meanwhile, the first arm body and the second arm body are also prevented from being deformed due to the relative motion interference, so as to ensure the structural safety of the first fork arm and the second fork arm and help to improve the service life of the support mechanism.

The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms as used herein are for the purpose of illustration only and do not indicate the only orientation of the embodiments.

[0054] The present application provides a vehicle, comprising a vehicle body and a sunshade assembly 200, the vehicle body is provided with a glass, and the sunshade assembly 200 is arranged on the vehicle body and cooperates with the glass, and the sunshade assembly 200 can cover or expose the glass.

[0055] The sunshade assembly 200 comprises a support mechanism 100, a curtain cloth 210 and a power mechanism 230, the support mechanism 100 has an extended state and a retracted state; the curtain cloth 210 is connected with the support mechanism 100; the power mechanism 230 is in driving connection with the support mechanism 100, and is used for driving the support mechanism 100 to switch between the extended state and the retracted state, when the support mechanism 100 is in the extended state, the support mechanism 100 drives the curtain cloth 210 to be unfolded, and when the support mechanism 100 is in the retracted state, the support mechanism 100 drives the curtain cloth 210 to be retracted.

[0056] For example, the sunshade assembly 200 can be, but is not limited to, a front windshield sunshade assembly, a sunroof sunshade assembly and the like.

[0057] Please refer to Figure 1 and Figure 2 , in particular, the sunshade assembly 200 further comprises a curtain cloth support rod 220, and the power mechanism 230 comprises a power source, a sliding rail 231, a first sliding unit 232, a second sliding unit 233 and a roller tube 234.

[0058] The power source can be connected with the sliding rail 231, or the power source can be separately arranged, or be arranged with other components, and can be flexibly selected according to actual needs.

[0059] The curtain cloth support rod 220 is connected with one end of the support mechanism 100, one end of the curtain cloth 210 is wound and arranged on the roller tube 234, and the other end of the curtain cloth 210 away from the roller tube 234 is fixed to the curtain cloth support rod 220.

[0060] It is to be noted that a winding shaft with a winding spring is arranged in the roller tube 234, and one end of the curtain cloth 210 is wound and arranged on the outside of the winding shaft, and when the curtain cloth 210 is pulled to be unfolded, the winding shaft can be rotated to automatically wind and retract the curtain cloth 210 through the rebounding force of the winding spring.

[0061] The first sliding unit 232 and the second sliding unit 233 are slidably installed on the slide rail 231, and the first sliding unit 232 and the second sliding unit 233 are respectively connected with the power source in transmission, so that the first sliding unit 232 and the second sliding unit 233 can approach or move away from each other; when the first sliding unit 232 and the second sliding unit 233 approach each other, the support mechanism 100 is in an extended state to drive the curtain cloth 210 to unfold, and when the first sliding unit 232 and the second sliding unit 233 move away from each other, the support mechanism 100 is in a retracted state to drive the curtain cloth 210 to be retracted.

[0062] It is easy to understand that when the first sliding unit 232 and the second sliding unit 233 move towards each other and approach, a pushing force will be respectively applied to the first fork arm 10 and the second fork arm 20, and then the support mechanism 100 moves to open and close, so that the support mechanism 100 can further push the curtain cloth support rod 220 to synchronously push the curtain cloth 210 to unfold to cover the glass. On the contrary, when the first sliding unit 232 and the second sliding unit 233 move away from each other, a pulling force will be respectively applied to the first fork arm 10 and the second fork arm 20, and then the support mechanism 100 moves to close, so that the support mechanism 100 can further pull the curtain cloth support rod 220 to synchronously pull the curtain cloth 210 to be retracted to expose the glass.

[0063] Please continue to refer to Figure 3 A support mechanism 100 according to an embodiment of the present application comprises a first fork arm 10 and a second fork arm 20. For example, the first fork arm 10 and the second fork arm 20 are designed as long strip-shaped rod members. The structure is simple and easy to obtain (but not limited to stamping process).

[0064] Please continue to refer to Figures 3 to 6 The first fork arm 10 comprises a first arm body 12 and a first mounting body 11 connected with each other, and the first mounting body 11 is provided with a receiving recess 111; the second fork arm 20 comprises a second arm body 22 and a second mounting body 21 connected with each other, and the second mounting body 21 is rotatably arranged in the receiving recess 111, so that the second arm body 22 and the first arm body 12 can be relatively opened or closed.

[0065] The first arm body 12 and the first mounting body 11 and the second arm body 22 and the second mounting body 21 can be an integral structure, or can be detachably assembled, which can be selected according to actual needs.

[0066] In the present application, the first arm body 12 and the first mounting body 11 and the second arm body 22 and the second mounting body 21 are designed as an integral structure to obtain higher connection strength and better structural performance.

[0067] When the first arm body 12 and the second arm body 22 are folded, the second arm body 22 is stacked along a first direction of the support mechanism 100 with the first arm body 12.

[0068] It should be noted that the support mechanism 100 in the folded state is a rectangular structure, and thus has a length direction, a width direction and a thickness direction.

[0069] The first direction mentioned in the present application is the width direction of the support mechanism 100, specifically Figure 4 and Figure 5 the direction of the arrow S1.

[0070] In summary, the support mechanism 100 of the present embodiment has the following advantages: the support mechanism 100 is applied to the sunshade assembly 200 and is connected with the curtain fabric 210 and the power mechanism 230, so as to drive the curtain fabric 210 to expand to shield the glass or to retract to expose the glass; the first fork arm 10 is designed to be connected with the first arm body 12 and the first mounting body 11, and the first mounting body 11 is provided with a receiving recess 111; the second fork arm 20 is designed to be connected with the second arm body 22 and the second mounting body 21, and the second mounting body 21 is rotatably installed in the receiving recess 111, so that the first fork arm 10 and the second fork arm 20 can relatively rotate and expand or fold, and the support mechanism 100 has the ability to drive the curtain fabric 210 to expand or retract; the second mounting body 21 is arranged in the receiving recess 111, so that only the first mounting body 11 and the second mounting body 21 form a cross-stacking effect to provide necessary support and positioning when the first fork arm 10 and the second fork arm 20 rotate relative to each other, but the first arm body 12 and the second arm body 22 are not cross-stacked, and the first arm body 12 and the second arm body 22 are stacked along the first direction of the support mechanism 100, so that there is no large-area stacking between the first arm body 12 and the second arm body 22, and noise is avoided when rotating relative to each other, and the first arm body 12 and the second arm body 22 are also prevented from deforming due to relative movement interference, so as to ensure the structural safety of the first fork arm 10 and the second fork arm 20 and prolong the service life of the support mechanism 100.

[0071] Please continue to refer to Figures 3 to 6 In one embodiment, the first arm body 12 includes a first arm rod 121 and a second arm rod 122, and the first arm rod 121 and the second arm rod 122 are arranged on both sides of the first mounting body 11 along a second direction of the support mechanism 100.

[0072] More specifically, one end of the first arm rod 121 is connected to the first mounting body 11, and the other end of the first arm rod 121 is arranged to extend away from the second arm rod 122 along the second direction of the support mechanism 100; one end of the second arm rod 122 is connected to the first mounting body 11, and the other end of the second arm rod 122 is arranged to extend away from the first arm rod 121 along the second direction of the support mechanism 100.

[0073] In this way, the first arm rod 121, the first mounting body 11 and the second arm rod 122 are connected to form a strip-shaped structure of the first fork arm 10, which is suitable for the size of the glass to be installed, and reduces the size in the width and thickness directions, thereby helping to reduce the installation space of the support mechanism 100.

[0074] Similarly, the second arm body 22 includes a third arm rod 221 and a fourth arm rod 222, which are arranged to be opposite and spaced apart on both sides of the second mounting body 21 along the second direction of the support mechanism 100.

[0075] More specifically, one end of the third arm rod 221 is connected to the second mounting body 21, and the other end of the third arm rod 221 is arranged to extend away from the fourth arm rod 222 along the second direction of the support mechanism 100; one end of the fourth arm rod 222 is connected to the second mounting body 21, and the other end of the fourth arm rod 222 is arranged to extend away from the third arm rod 221 along the second direction of the support mechanism 100.

[0076] In this way, the third arm rod 221, the second mounting body 21 and the fourth arm rod 222 are connected to form a strip-shaped structure of the second fork arm 20, which is suitable for the size of the glass to be installed, and reduces the size in the width and thickness directions, thereby helping to reduce the installation space of the support mechanism 100.

[0077] It should be noted that the length of the first fork arm 10 is equal to or close to the length of the second fork arm 20, which ensures the structural regularity of the support mechanism 100.

[0078] It should also be noted that the second direction mentioned in the present application is the length direction of the support mechanism 100, specifically the direction of the arrow S2 in Figure 4 and Figure 5 .

[0079] Please continue to refer to Figures 4 to 5, further, on the basis of the above-mentioned embodiment, the first arm rod 121 has a first side surface 121a and a second side surface 121b oppositely arranged along the first direction, the second arm rod 122 has a third side surface 122a and a fourth side surface 122b oppositely arranged along the first direction, the first side surface 121a and the fourth side surface 122b are both located between the second side surface 121b and the third side surface 122a, and the second side surface 121b and the third side surface 122a are spaced apart. Wherein, the first side surface 121a and the fourth side surface 122b are coplanarly arranged or the first side surface 121a and the fourth side surface 122b are staggeredly arranged along the first direction.

[0080] It is easy to understand that when the widths (i.e. the dimensions along the first direction) of the first arm rod 121 and the second arm rod 122 are equal, the first side surface 121a and the fourth side surface 122b are coplanarly arranged; when the widths (i.e. the dimensions along the first direction) of the first arm rod 121 and the second arm rod 122 are not equal, the first side surface 121a and the fourth side surface 122b are staggeredly arranged.

[0081] Further, the third arm rod 221 has a fifth side surface 221a and a sixth side surface 221b oppositely arranged along the first direction, the fourth arm rod 222 has a seventh side surface 222a and an eighth side surface 222b oppositely arranged along the first direction, the sixth side surface 221b and the seventh side surface 222a are both located between the fifth side surface 221a and the eighth side surface 222b, and the fifth side surface 221a and the eighth side surface 222b are spaced apart. Wherein, the sixth side surface 221b and the seventh side surface 222a are coplanarly arranged or the sixth side surface 221b and the seventh side surface 222a are staggeredly arranged along the first direction.

[0082] It is easy to understand that when the widths (i.e. the dimensions along the first direction) of the third arm rod 221 and the fourth arm rod 222 are equal, the sixth side surface 221b and the seventh side surface 222a are coplanarly arranged; when the widths (i.e. the dimensions along the first direction) of the third arm rod 221 and the fourth arm rod 222 are not equal, the sixth side surface 221b and the seventh side surface 222a are staggeredly arranged.
