Description

Technical Field

[0001] This application relates to the field of projection devices, and more specifically, to a curtain device and a control method. Background Art

[0002] With the development of vehicle technology, it has become possible to install a curtain in a vehicle cockpit. Currently, a slide-type curtain is usually adopted in a vehicle cockpit. On the one hand, the slide-type curtain often has a significant deteriorating effect on the aesthetic appearance of the cockpit. On the other hand, the layout method of the slide-type curtain is severely limited by the vehicle structure. In addition, different users may have different usage requirements for the vehicle-mounted curtain in different scenarios.

[0003] Therefore, how to meet the user's usage requirements for the vehicle-mounted curtain with as little deterioration of the cockpit shape as possible has become a problem to be solved. Summary of the Invention

[0004] This application provides a curtain device and a control method, which can meet different usage requirements of users for the curtain device in the cockpit scenario with as little impact on the cockpit shape as possible.

[0005] In a first aspect, a curtain device is provided. The curtain device can be installed in a vehicle, such as in the cockpit of a vehicle.

[0006] The curtain device includes a winding mechanism arranged at the top, and a main curtain and an extension curtain connected to the winding mechanism at the top. The unfolded states of the curtain device include a first unfolded state and a second unfolded state. In the first unfolded state, the main curtain and the extension curtain are unfolded along a first direction, the extension curtain is located at the back of the main curtain, and in the projection direction of the curtain device, part or all of the area of the extension curtain overlaps with the main curtain. In the second unfolded state, the main curtain maintains the posture in the first unfolded state, and the extension curtain unfolds horizontally relative to the main curtain.

[0007] In the cockpit scenario, the traditional solution often adopts a slide-type curtain. Due to the limitation of the vehicle shape, the slide-type curtain often has a significant deteriorating effect on the aesthetic appearance of the cockpit. Moreover, the layout method of the slide-type curtain is severely limited by the vehicle shape. In addition, in different usage scenarios (such as a home scenario, a business scenario), users may have different usage requirements for the curtain.

[0008] In the embodiment of the present application, in the first unfolded state, the curtain device can be used as a conventional projection curtain. There are gaps on both sides of the curtain, which can connect the front and rear spaces of the cockpit, facilitating communication between crew members. In the second unfolded state, the extended curtain blocks the gaps on both sides. The curtain device can effectively partition the cockpit space, provide a certain privacy protection effect, provide a more private space for passengers, and enable the driver to focus more on driving. Moreover, since the curtain device does not need to be provided with a slide rail, it can reduce the deterioration effect of the curtain device on the cockpit shape and is also beneficial to the flexible layout of the curtain device on the vehicle.

[0009] In combination with the first aspect, in some implementation manners of the first aspect, the winding mechanism may include a main curtain winding roller and an extended curtain winding roller to fixedly connect the main curtain and the extended curtain respectively. The winding mechanism may further include a first motor and a first transmission assembly. The output end of the first motor is in transmission connection with the first winding roller to drive the first winding roller to rotate. The first transmission assembly is used to transmit the second winding roller to the first motor so that the first motor drives the second winding roller to rotate. Wherein, the first winding roller is one of the main curtain winding roller and the extended curtain winding roller, and the second winding roller is the other of the main curtain winding roller and the extended curtain winding roller.

[0010] In the embodiment of the present application, through the first transmission assembly, the first motor can drive the main curtain winding roller and the extended curtain winding roller simultaneously, which can reduce the number of motors used in the curtain device, reduce the cost of the curtain device, and reduce the speed difference when the main curtain and the extended curtain move in the first direction.

[0011] In combination with the first aspect, in some implementation manners of the first aspect, the first transmission assembly may include a first transmission rod and a second transmission assembly. The first transmission rod can pass through the second winding roller and be in transmission connection with the second winding roller, and the second winding roller can move horizontally relative to the first transmission rod. The second transmission assembly can be used to transmit the first transmission rod to the first motor so that the first motor drives the first transmission rod to rotate.

[0012] In one embodiment, the second winding roller is the winding roller of the extended curtain. The second winding roller is in transmission connection with the first transmission rod and can move horizontally relative to the first transmission rod.

[0013] In the embodiment of the present application, when the first transmission rod rotates along its axis, it can drive the second winding roller to rotate, and it can also allow the second winding roller to move horizontally along the first transmission rod, which can reduce the design difficulty of the transmission assembly, reduce the number of parts in the winding mechanism, and reduce the cost.

[0014] In combination with the first aspect, in some implementations of the first aspect, the rewinding mechanism may further include a first guiding member and a second guiding member, and the gap between the first guiding member and the second guiding member is less than or equal to a first threshold value. The main curtain extended from the main curtain rewinding roller and the extended curtain extended from the extended curtain rewinding roller may pass through the gap and then unfold along the first direction.

[0015] In the embodiments of the present application, the main curtain and the extended curtain pass through the gap between the first guiding member and the second guiding member, which can keep the gap between the main curtain and the extended curtain as small as possible in the unfolded state, and can improve the quality sense of the curtain device.

[0016] In combination with the first aspect, in some implementations of the first aspect, the rewinding mechanism may further include a third guiding member and a fourth guiding member. The first guiding surface provided on the third guiding member may be parallel to the second guiding surface provided on the fourth guiding member. The main curtain extended from the main curtain rewinding roller may pass through the gap after passing through the first guiding surface, and the extended curtain extended from the extended curtain rewinding roller may pass through the gap after passing through the second guiding surface.

[0017] Since the main curtain and the extended curtain are respectively wound on their own rewinding rollers, when the rewinding roller rotates to unfold or retract the curtain, the outer diameter of the rotating assembly formed by the curtain and its rewinding roller will change, which may cause the unfolding speeds of different curtains in the first direction to be different. In the embodiments of the present application, by providing the third guiding member and the fourth guiding member, it is beneficial for different curtains to maintain the same motion state in the first direction.

[0018] In combination with the first aspect, in some implementations of the first aspect, the rewinding mechanism may further include a second motor and a third transmission assembly. The third transmission assembly may be used to drive-connect the extended curtain rewinding roller to the second motor, so that the second motor drives the extended curtain rewinding roller to move along the second direction.

[0019] In combination with the first aspect, in some implementations of the first aspect, the third transmission assembly may include a second transmission rod extending along the second direction, a base for setting the extended curtain rewinding roller, and a fourth transmission assembly. The base may be provided with a first through hole and a second through hole. The first transmission rod may be arranged through the first through hole, and the first transmission rod can freely rotate around the second direction in the first through hole. The second transmission rod may be arranged through the second through hole and be in transmission connection with the base. The base may be fixedly connected to the extended curtain rewinding roller in the second direction, and the extended curtain rewinding roller and the base can rotate relative to the first transmission rod. The fourth transmission assembly may be used to drive-connect the second transmission rod to the second motor, so that the second motor drives the second transmission rod to rotate.

[0020] In the embodiments of the present application, the base can support the winding roller of the extended curtain, can not interfere with the rotation of the winding roller of the extended curtain, and can also drive the winding roller of the extended curtain to move horizontally. In this way, the design difficulty of the transmission component can be reduced, the number of parts in the winding mechanism can be reduced, and the cost can be lowered.

[0021] Combined with the first aspect, in some implementation manners of the first aspect, the second through hole can be a threaded hole, and the second transmission rod can be a threaded rod.

[0022] Combined with the first aspect, in some implementation manners of the first aspect, the curtain device can further include a counterweight mechanism at the bottom, and the bottoms of the main curtain and the extended curtain can be arranged on the counterweight mechanism.

[0023] Combined with the first aspect, in some implementation manners of the first aspect, the curtain device can further include a bracket arranged between the winding mechanism and the counterweight mechanism. The bracket can include a first connecting member and a second connecting member. One end of the first connecting member can be hinged to one end of the second connecting member. The other end of the first connecting member can be arranged on the winding mechanism, and the other end of the second connecting member can be arranged on the counterweight mechanism.

[0024] In the cockpit scenario, the user may accidentally touch the curtain main body or the counterweight mechanism, and the operation of the vehicle may cause the counterweight mechanism to shake, and the shape of the curtain main body may change accordingly. In the embodiments of the present application, by arranging a bracket between the winding mechanism and the counterweight mechanism, the shaking of the counterweight mechanism can be avoided, which is beneficial to maintaining the shape of the curtain main body.

[0025] Combined with the first aspect, in some implementation manners of the first aspect, the bracket can further include an elastic component. One end of the elastic component can be arranged on the first connecting member, and the other end of the elastic component can be arranged on the second connecting member. When the curtain device is in the retracted state, the elastic component is in a stretched state.

[0026] In the actual scenario, the user may accidentally touch the counterweight mechanism, and the operation of the vehicle may cause the counterweight mechanism to shake, and the shape of the curtain main body may change accordingly. In the embodiments of the present application, by arranging an elastic connection component, the bracket can resist the above external interference, which is beneficial to maintaining the shape of the curtain main body and is also beneficial to reducing the weight of the counterweight mechanism.

[0027] In combination with the first aspect, in certain implementations of the first aspect, the bracket may further include a transmission mechanism. The transmission mechanism may include: a first universal joint disposed on the winding mechanism, a second universal joint disposed on the counterweight mechanism, and a fifth transmission component for drivingly connecting the second universal joint to the first universal joint. The winding mechanism may further include a sixth transmission component for drivingly connecting the first universal joint to the base so as to convert the movement of the base in the second direction into the rotation of the first universal joint. The counterweight mechanism may include: a first curtain bracket fixedly connected to the bottom of the extended curtain, and a seventh transmission component. The seventh transmission component may be used for drivingly connecting the first curtain bracket to the second universal joint so as to convert the rotation of the second universal joint into the movement of the first curtain bracket in the second direction.

[0028] In an actual scenario, the curtain usually uses a flexible material. Merely driving the winding roller of the extended curtain to move horizontally may only be able to drive the top of the extended curtain to move horizontally, but it is difficult to effectively drive the bottom of the extended curtain to move horizontally. Moreover, directly arranging a motor for driving the bottom of the extended curtain to move horizontally in the counterweight mechanism will cause an increase in the weight of the counterweight mechanism. Additionally, when different motors are used to drive the top and bottom of the extended curtain to move in the second direction respectively, relatively high motor control precision may be required.

[0029] In the embodiments of the present application, by arranging a transmission mechanism on the bracket, the second motor can drive the top and bottom of the extended curtain to move horizontally along corresponding transmission paths respectively, and can effectively maintain the posture of the extended curtain with relatively low control precision, which is beneficial to improving the quality perception of the product.

[0030] In combination with the first aspect, in certain implementations of the first aspect, the fifth transmission component may include a third universal joint and a fourth universal joint disposed around the hinge portion of the first connecting member and the second connecting member. The fourth universal joint is drivingly connected to the third universal joint. The fifth transmission component may further include: a first connecting component extending along a first axis. The first connecting component may include a third connecting member and a fourth connecting member. The third connecting member and the fourth component can move relative to each other along the first axis, and the fourth connecting member may be used for transmitting the axial rotation of the third connecting member along the first axis to the outside of the connecting component. The first connecting component may be disposed between the first universal joint and the third universal joint, or may be disposed between the fourth universal joint and the second universal joint.

[0031] In the embodiments of the present application, by arranging a plurality of universal joints and the first connecting component, the transmission mechanism can occupy a smaller space in the first direction after being folded, so that the counterweight mechanism and the winding mechanism can fit together in the retracted state.

[0032] In combination with the first aspect, in certain implementations of the first aspect, the sixth transmission component includes a belt fixedly arranged with the base, and the belt is in transmission connection with the first universal joint; and / or, the seventh transmission component includes a rack arranged on the first curtain bracket and a gear arranged on the second universal joint.

[0033] In combination with the first aspect, in certain implementations of the first aspect, the winding mechanism may further include a first limiting member, and the first limiting member may be used for: when the curtain device switches between the retracted state and the first deployed state, restricting the rotation of the first universal joint. And / or, the counterweight mechanism may further include a second limiting member, and the second limiting member may be used for: when the curtain device switches between the retracted state and the first deployed state, restricting the rotation of the second universal joint.

[0034] In the embodiments of the present application, when the curtain device switches between the retracted state and the first deployed state, the attitude of the bracket will change. By restricting the rotation of the transmission mechanism, it is possible to prevent the extended curtain from moving horizontally during an unexpected period.

[0035] In combination with the first aspect, in certain implementations of the first aspect, when the curtain device is in the first deployed state or the second deployed state, the attitude of the main curtain is the first attitude. The winding mechanism may further include a third limiting member, and the third limiting member may be used for: when the main curtain is in the first attitude, restricting the relative rotation between the first connecting member and the winding mechanism. And / or, the counterweight mechanism may further include a fourth limiting member, and the fourth limiting member may be used for: when the main curtain is in the first attitude, restricting the relative rotation between the second connecting member and the counterweight mechanism.

[0036] In the embodiments of the present application, by restricting the rotation of the first connecting member and the second connecting member, the attitude of the bracket can be maintained, and an unexpected change in the attitude of the main curtain can be avoided.

[0037] In a second aspect, a control method is provided. This method may be executed by the curtain device, or may be executed by the control device of the curtain device, or may be executed by a component in the control device (such as a processor, a processing circuit, a chip), or may be executed by a cockpit or a vehicle provided with the curtain device or the control device.

[0039] Among them, the curtain device includes a winding mechanism arranged at the top, and a main curtain and an extended curtain connected to the winding mechanism at the top. In the first unfolded state, the main curtain and the extended curtain are unfolded along the first direction, the extended curtain is at the back of the main curtain, and in the projection direction of the curtain device, part or all of the area of the extended curtain overlaps with the main curtain. In the second unfolded state, the main curtain maintains the posture in the first unfolded state, and the extended curtain unfolds horizontally relative to the main curtain.

[0040] In combination with the second aspect, in some implementation manners of the second aspect, the winding mechanism may include a main curtain winding roller and an extended curtain winding roller to fixedly connect the main curtain and the extended curtain respectively. The winding mechanism may further include a first motor and a first transmission component. The output end of the first motor may be in transmission connection with the first winding roller to drive the first winding roller to rotate. The first transmission component may be used to transmit the second winding roller to the first motor so that the first motor drives the second winding roller to rotate. Among them, the first winding roller is one of the main curtain winding roller and the extended curtain winding roller, and the second winding roller is the other of the main curtain winding roller and the extended curtain winding roller.

[0041] In combination with the second aspect, in some implementation manners of the second aspect, the current state of the curtain device may be one of the retracted state and the first unfolded state, and the target state may be the other of the retracted state and the first unfolded state. Controlling the curtain device to be in the target state according to the control information may include: controlling the first motor to rotate according to the control information.

[0042] In combination with the second aspect, in some implementation manners of the second aspect, the winding mechanism may further include a second motor and a third transmission component.

The method may further include: before the second motor rotates, controlling the first motor to rotate a first preset angle in the first driving direction; after the second motor stops rotating, controlling the first motor to rotate a second preset angle in the second driving direction.

[0044] In combination with the second aspect, in certain implementations of the second aspect, the curtain device may further include a counterweight mechanism and a bracket disposed between the winding mechanism and the counterweight mechanism. The bracket may include a first connecting member and a second connecting member. One end of the first connecting member may be hinged to one end of the second connecting member.

[0069] Next, the technical solutions in the present application will be described in conjunction with the accompanying drawings.

[0070] The following detailed description of the embodiments and the accompanying drawings are used to exemplarily illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0071] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and other forms thereof, such as the third-person singular form "comprises" and the present participle form "comprising", are to be construed in an open, inclusive sense, i.e., "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example", or "some examples", etc., are intended to indicate that the specific features, structures, materials, or characteristics related to the embodiment or example are included in at least one embodiment or example of the present application. The schematic representations of the above terms do not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials, or characteristics can be included in any one or more embodiments or examples in any suitable manner.

[0072] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0073] The directional terms appearing in the following description are all the directions shown in the figures and do not limit the specific structures in the embodiments of the present application. In the description of the embodiments of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0074] Referring to an "embodiment" in the embodiments of the present application means that the specific features, structures, or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appearing at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0075] In this application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this application, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0076] In addition, the use of "based on" implies openness and inclusiveness because a process, step, calculation, or other action "based on" one or more of the stated conditions or values can, in practice, be based on additional conditions or values beyond the stated ones.

[0077] In the embodiments of this application, "about", "substantially", or "approximate" includes the stated value and the average value within an acceptable deviation range of the specific value, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurement being discussed and the errors associated with the measurement of the specific quantity, i.e., the limitations of the measurement system.

[0078] Currently, for in-vehicle curtains, the slide-rail curtain is a commonly used curtain form. Structurally, the slide-rail curtain can include a curtain body and slide rails on both the left and right sides. When the curtain is not in use, the curtain body can be in a retracted state. For example, the winding roller of the curtain body can be installed on the ceiling of the cockpit. When the curtain is in use, the winding roller rotates, and the curtain body can be unfolded along the slide rails.

[0079] In a possible design, the slide rails are fixedly arranged in the cockpit space of the vehicle, such as being arranged vertically near the B-pillar of the vehicle. The slide rails can play a guiding and limiting role, enabling the curtain body to be unfolded along the slide rails from the retracted state and being difficult to shake in the limiting direction. However, when the curtain is not in use, although the curtain body is in a retracted state, since the slide rails are fixedly arranged in the cockpit, the slide rails will occupy a part of the space in the cockpit. Additionally, the curtain body used in the slide-rail curtain is usually in a regular shape such as a rectangle, while the side wall of the cockpit is often a complex curved surface. To ensure the aesthetic appearance of the cockpit styling, decorative parts such as interior trim panels are usually provided between the slide rails and the side wall of the cockpit. Thus, even when the curtain is not in use, this part of the decorative parts will cause additional partitioning of the cockpit space, inevitably affecting the space in the cockpit and the user's riding experience.

[0080] In another possible design, the slide rail can be set to be movable. When the curtain is not in use, the slide rail can be in a retracted state; when the curtain is in use, the slide rail is in an open state, providing a guiding and limiting function for the curtain. For example, by setting a shielding / hiding structure on the vehicle interior part (such as the interior panel near the vehicle B-pillar), the slide rail in the retracted state can be shielded; when the curtain is in use, the slide rail can pop out from the shielding / hiding structure and be fixed in a specified posture. However, since the slide rail is often linear, while the shape of the vehicle (such as the B-pillar) is often curved / surfaced, if the shielding / hiding structure set on the interior panel near the B-pillar is small, it will be difficult to completely shield the slide rail, and the exposure of the slide rail will affect the quality sense of the cockpit; if a larger shielding / hiding structure is set to shield the slide rail, it will be reflected as a large bulge here on the side of the cockpit, affecting the aesthetic degree of the cockpit.

[0081] To ensure the passable space at the door and to reduce the interference of the slide rail to the user's activity space, for the slide rail type curtain, in the longitudinal axis direction of the vehicle, the slide rail type curtain is usually set outside the area occupied by the door, resulting in extremely limited layout space of the slide rail type curtain in the cockpit. For example, in the longitudinal axis direction of the vehicle, the slide rail type curtain is often set in the area occupied by the vehicle B-pillar. Moreover, during the assembly process, the curtain main body and the slide rail usually need to be assembled on the vehicle separately; to ensure the guiding and limiting performance of the slide rail to the curtain main body, the assembly of the slide rail type curtain often requires high installation accuracy. In addition, when the slide rail is damaged or distorted, it will also affect the use of the curtain, which will bring higher maintenance costs to the user.

[0082] In view of this, the embodiments of the present application provide a curtain device and a control method, which can be applicable to various use scenarios of the cockpit.

[0083] Exemplarily, the curtain device 10 can include a winding mechanism 100, a main curtain 200, and one or more extended curtains (such as extended curtains 300, 400).

[0084] The winding mechanism 100 can be set at the top of the curtain device 10, and the tops of the main curtain 200 and the extended curtains (300, 400) are fixedly connected to the winding mechanism 100. For example, the winding mechanism 100 can include the winding rollers, motors, transmission components, brackets, etc. of each curtain.

[0085] In some possible implementation manners, the curtain device 10 can further include a counterweight mechanism 500 set at the bottom. The bottoms of the main curtain 200 and the extended curtains (300, 400) can be fixedly connected to the counterweight mechanism 500. The main curtain 200 and the extended curtains (300, 400) are set between the winding mechanism 100 and the counterweight mechanism 500.

[0086] Exemplarily, the winding rollers of different extension curtains can be arranged along the same axis. Multiple extension curtains can also be arranged along different axes; these multiple axes can be parallel to each other or not parallel. The embodiments of the present application do not limit the specific arrangement manner of each curtain.

[0087] In one embodiment, the winding rollers of the extension curtains 300 and 400 can be arranged along the same axis, and the winding roller of the main curtain 200 can be arranged along another axis, and the two axes can be parallel. For example, in the top view of this arrangement, it can be as shown in Figure 1 (a); wherein, axis 1 can be parallel to axis 2, or axis 1 and axis 2 can be the same axis. Figure 1 (b) in can be taken as an implementation manner of the curtain device 10 in this arrangement.

[0088] Exemplarily, since devices such as seats arranged in the cockpit may affect the unfolding of the curtain device 10, the winding rollers of the extension curtains 300 and 400 can be arranged along non-parallel axes.

[0089] In one embodiment, the winding rollers of the extension curtains 300 and 400 can be arranged along different horizontal directions, that is, the winding rollers of the extension curtains can be inclined in the front-rear direction. For example, in the top view of this arrangement, it can be as shown in Figure 1 (c); wherein, axis 1 and axis 2 are not parallel. For another example, the axis of the winding roller of the main curtain 200 may not be a straight line. Setting the axis of the main curtain as an arc can utilize the longitudinal space to provide a larger visible area within a limited horizontal space. Arranging it inclined in the front-rear direction can better fit the contour of the cockpit and provide a more complete closing effect.

[0090] In another embodiment, the winding rollers of the extension curtains 300 and 400 can be inclined in the vertical direction. For example, in the front view of this arrangement, it can be as shown in Figure 1 (d). Wherein, axis 1 and axis 2 are not arranged along the horizontal direction, but are inclined in the vertical direction. Arranging it inclined downward along the moving unfolding direction can utilize gravity to unfold the extension curtain and make the unfolding process smoother.

[0091] The direction of the axis arrangement can be adjusted according to the cockpit space accordingly, and no more examples will be given.

[0092] It can be understood that other components other than the main curtain 200, the extension curtains 300 and 400 are not shown in Figure 1 (a), (c) and (d); in Figure 1 (a), (c) and (d), the main curtain 200, the extension curtains 300 and 400 are in the wound state.

[0093] Based on the application scenario, the curtain device 10 can be in different states. For example, the curtain device 10 can be in a retracted state or an unfolded state. For the sake of convenience in description, it is assumed hereinafter that the winding rollers of the extended curtains 300 and 400 are arranged along the same axis.

[0094] Exemplarily, in the retracted state, the winding mechanism 100 can wind part or all of each curtain. For example, in the retracted state, the winding mechanism 100 and the counterweight mechanism 500 can be in contact with each other in the vertical direction, as shown in (b) of Figure 1 . Also, for example, some components of the curtain device 10 may interfere with the vertical movement of the counterweight mechanism 500, resulting in a gap between the winding mechanism 100 and the counterweight mechanism 500 in the vertical direction in the retracted state.

[0095] Exemplarily, the unfolded state of the curtain device 10 can include a first unfolded state and a second unfolded state. Hereinafter, taking the implementation manner shown in (b) of Figure 1 as an example, in combination with Figure 2 and Figure 3 , the first unfolded state and the second unfolded state will be briefly described respectively.

[0096] As shown in Figure 2 and Figure 3 , the main curtain 200 can be rectangular in the unfolded state. In some possible implementation manners, the main curtain 200 can also be in other shapes in the unfolded state, such as trapezoidal, square, etc., and the embodiments of the present application do not limit this.

[0097] In the first unfolded state, the main curtain 200 and the extended curtains (300, 400) are unfolded along the first direction, and the extended curtains (300, 400) can be located at the back of the main curtain 200. In the projection direction of the curtain device 10, part or all of the extended curtains (300, 400) overlap with the main curtain 200. For example, the first direction can be the vertical direction. Also, for example, the curtains extended from the winding rollers of each curtain may not be directly in the vertical direction, and after passing through the guiding member / structure, each curtain can be unfolded along the vertical direction.

[0098] In some possible implementation manners, in the first unfolded state, the unfolded area of the curtain device 10 is determined by the unfolded area of the main curtain 200 in the first direction.

[0099] In one embodiment, Figure 2 shows views of the curtain device 10 in the first unfolded state at different angles. Figure 2 (a) in Figure 2 can be taken as an example of the front view of the curtain device 10, and

[0100] As shown Figure 2 in (a) of FIG., in the projection direction of the curtain device 10, the extended curtains 300 and 400 can be completely hidden behind the main curtain 200. In this scenario, the area 11 is the unfolding area of the curtain device 10, and this area 11 is determined according to the unfolding area of the main curtain 200 in the first direction. In Figure 2 the scenario shown, the side boundaries of the main curtain 200 can form the left and right side boundaries of the area 11.

[0101] In the embodiments of the present application, by setting the positional relationship between the extended curtains 300, 400 and the main curtain 200, the main curtain 200 can block the extended curtains 300, 400 in the first unfolded state, which can avoid the influence of the protrusion of the extended curtains on the user experience.

[0102] In another embodiment, in the first unfolded state, in the projection direction of the curtain device 10, part of the area of the extended curtains (300, 400) cannot be completely hidden by the main curtain 200. In this scenario, the side boundaries of the extended curtains (300, 400) can form the side boundaries of the unfolding area of the curtain device.

[0103] In the second unfolded state, the main curtain 200 maintains the posture in the first unfolded state, and the extended curtains (300, 400) are unfolded horizontally relative to the main curtain 200. That is to say, when the curtain device 10 is switched from the first unfolded state to the second unfolded state, the main curtain 200 maintains its posture unchanged, and the extended curtains (300, 400) move horizontally relative to the main curtain 200 until the curtain device 10 is in the posture corresponding to the second unfolded state.

[0104] In some possible implementation manners, in the second unfolded state, the unfolding area of the curtain device 10 is determined by the unfolding area of the main curtain 200 in the first direction and the area where the extended curtains (300, 400) protrude from the main curtain horizontally.

[0105] In one embodiment, Figure 3 shows views of the curtain device 10 at different angles in the second unfolded state. Figure 3 (a) in FIG. can be used as an example of the front view of the curtain device 10, Figure 3 (b) in FIG. can be used as an example of the rear view of the curtain device 10. Relative to Figure 2 the first unfolded state in FIG., the extended curtains 300 and 400 move horizontally to the left and right sides respectively until the curtain device 10 is in the second unfolded state. During this process, although the winding rollers of each curtain may not rotate, the curtain device 10 can still present an effect of unfolding horizontally.

[0106] In this scenario, area 12 is the deployment area of the curtain device 10, and this area 12 may include area 11, area 13, and area 14. Area 13 may be the area where the extended curtain 300 extends beyond the main curtain 200 in the horizontal direction, and area 14 may be the area where the extended curtain 400 extends beyond the main curtain 200 in the horizontal direction. As shown in (b) of Figure 3 , a part of the extended curtain 300 may be in area 13, and another part may be in area 11; a part of the extended curtain 400 may be in area 14, and another part may be in area 11.

[0107] Exemplarily, in the scenario of adopting the layout shown in (c) of Figure 1 , when the curtain device 10 is switched from the first deployed state to the second deployed state, the extended curtain 300 may move to the left along axis 1, and the extended curtain 400 may move to the right along axis 2, that is, the extended curtains 300 and 400 are deployed on the left and right sides in the horizontal direction.

[0108] Exemplarily, in the scenario of adopting the layout shown in (d) of Figure 1 , when the curtain device 10 is switched from the first deployed state to the second deployed state, although axis 1 and axis 2 are inclined in the vertical direction, due to their horizontal components, the extended curtain 300 may move to the left along axis 1, and the extended curtain 400 may move to the right along axis 2, presenting as the extended curtains unfolding to both sides in the horizontal direction relative to the main curtain.

[0109] In some possible implementation manners, since the internal space of the vehicle cockpit is irregular, the curtain device 10 provided in the vehicle cockpit may not be symmetric along the longitudinal plane of the vehicle. For example, when the curtain device 10 is switched from the first deployed state to the second deployed state, one extended curtain (such as the extended curtain 300) may be controlled to move in the horizontal direction, while the other extended curtain (such as the extended curtain 400) maintains its current posture unchanged. For another example, based on the installation position of the curtain device 10 in the cockpit, different horizontal deployment speeds may be set for the extended curtains 300 and 400.

[0110] Exemplarily, the winding mechanism 100 can be used to drive the switching of the curtain device between the retracted state and the deployed state. For example, by controlling the main curtain 200 and the extended curtains (300, 400) to retract or deploy in the vertical direction, the winding mechanism 100 can control the switching of the curtain device 10 between the retracted state and the first deployed state. For another example, by the movement of the extended curtains (300, 400) relative to the main curtain 200 in the horizontal direction, the winding mechanism 100 can control the switching of the curtain device 10 between the first deployed state and the second deployed state.

[0111] Exemplarily, the winding mechanism 100 includes a bracket assembly 101. Components such as the motor, transmission mechanism, and winding rollers for each curtain included in the winding mechanism 100 can be fixed and installed on the bracket assembly 101. The bracket assembly 101 can be composed of one or more components.

[0112] One end of the main curtain 200 can be arranged on the winding roller 110, and the other end of the main curtain 200 can be arranged on the counterweight mechanism 500. One end of the extension curtains 300 and 400 can be arranged on the winding rollers 120 and 130, and the other end of the extension curtains can be arranged on the counterweight mechanism 500.

[0113] In one embodiment, taking the extension curtain 300 as an example, one end of the extension curtain 300 can be fixedly connected to its winding roller 120, and the other end can be fixedly connected to the counterweight mechanism 500. For example, the extension curtain 300 can be fixedly connected to the winding roller 120 and the counterweight mechanism 500 by means of bonding or the like.

[0114] Exemplarily, different motors can be used to drive the winding rollers of the main curtain and the extension curtains to rotate respectively, so that the main curtain 200, the extension curtains 300 and 400 can move in the first direction. For example, three motors can be used to drive the winding rollers 110, 120, and 130 respectively. Another example is that the winding rollers 120 and 130 of the extension curtains 300 and 400 can be arranged on the same transmission rod, and one motor can be used to drive the transmission rod to achieve the effect of simultaneously driving the winding rollers 120 and 130 to rotate. In this way, the risk of the posture distortion of the curtain body and the counterweight mechanism caused by the inconsistent rotation states of the winding rollers 120 and 130 can be reduced.

[0115] In an actual scenario, when the moving speeds of different curtains in the first direction are inconsistent, it may also cause the posture distortion of the counterweight mechanism 500.

[0116] In some possible implementation manners, the winding rollers included in the winding mechanism 100 can be divided into a first winding roller and a second winding roller. The first winding roller can be one of the winding rollers for the main curtain and the extension curtains, and the second winding roller can be the other of the winding rollers for the main curtain and the extension curtains. The winding mechanism 100 can further include a first motor and a first transmission assembly. The output end of the first driving motor can be in transmission connection with the first winding roller to drive the first winding roller to rotate. The first transmission assembly can transmit the second winding roller to the first motor so that the first motor drives the second winding roller to rotate.

[0117] Assume that the first winding roller is the winding roller 110 of the main curtain, and the winding rollers (120, 130) of the extended curtain are the second winding rollers. In this way, the winding roller 110 of the main curtain can be referred to as the first winding roller 110, and the winding rollers 120, 130 of the extended curtain can be referred to as the second winding rollers 120, 130. For example, the winding roller 110 of the main curtain can be directly driven by a motor, and the winding rollers (120, 130) of the extended curtain can be drivingly connected to the motor through belt drive, chain drive, gear drive or compound drive, etc.

[0118] In the embodiment of the present application, through the first transmission assembly, the first motor can drive the main curtain winding roller and the extended curtain winding roller at the same time, which can reduce the number of motors used in the curtain device, reduce the cost of the curtain device, and reduce the speed difference when the main curtain and the extended curtain move in the first direction.

[0119] Exemplarily, the first transmission assembly can include a first transmission rod and a second transmission assembly. The second winding roller can be provided with a through hole, the first transmission rod can pass through the second winding roller and be drivingly connected to the second winding roller, and the second winding roller can move horizontally relative to the first transmission rod. For example, the second winding rollers 120, 130 can be provided with through holes extending in the second direction; the first transmission rod can extend in the second direction and be disposed in the through hole, so that the second winding rollers 120, 130 can translate relative to the first transmission rod in the second direction. Again, for example, the first transmission rod can include a portion extending in the second direction, and the second winding rollers (120, 130) can be disposed on this portion. The above-mentioned second direction can be a certain horizontal direction.

[0120] In one embodiment, the first transmission rod can be provided with an external spline, and the second winding rollers 120, 130 can be provided with internal splines at the through holes where the first transmission rod is disposed. In this way, the second winding rollers 120, 130 can move relative to the first transmission rod in the second direction and can rotate around the axis of the first transmission rod.

[0121] In another embodiment, the cross-section of the first transmission rod perpendicular to the second direction can be in the shape of a cross, a triangle, a rectangle, etc., and the second winding rollers 120, 130 can be provided with shaping holes matching the above cross-section, so that the second shaping rollers (120, 130) can move in the second direction after being matched with the first transmission rod and can rotate around the axis of the first transmission rod.

[0122] In another embodiment, the winding mechanism 100 may be provided with a plurality of first transmission rods to respectively arrange the winding rollers 120 and 130 of the extension curtains 300 and 400. Correspondingly, the winding mechanism 100 may include multiple sets of second transmission components. That is to say, the motor 140 can drive the two first transmission rods to rotate through two different transmission mechanisms respectively, so as to achieve the effect of driving the winding rollers 120 and 130 respectively. For example, when the curtain arrangement shown in (c) and (d) of Figure 1 is adopted, the winding rollers of the extension curtains 300 and 400 can be arranged on different transmission rods. In this scenario, the extension curtains 300 and 400 can respectively correspond to two different second directions. For example, the second direction corresponding to the extension curtain 300 can be parallel to the axis 1, and the second direction corresponding to the extension curtain 400 can be parallel to the axis 2.

[0123] In another embodiment, the extension curtains 300 and 400 can be arranged on the same first transmission rod. By this means, only one set of transmission components can be used to achieve the effect of simultaneously driving the winding rollers 120 and 130 to rotate, which can reduce the number of parts in the winding mechanism, improve the assembly speed of the curtain device, and reduce the cost of the curtain device.

[0124] In the embodiment of the present application, when the first transmission rod rotates along its axis, it can drive the second winding roller to rotate, and the second winding roller is also allowed to move horizontally along the first transmission rod, which can reduce the design difficulty of the transmission components, reduce the number of parts in the winding mechanism, and reduce the cost.

[0125] Suppose the winding rollers of the main curtain and the extension curtain are respectively arranged on the front and rear sides of the winding mechanism 100. Combining Figure 4 and Figure 5 briefly introduce the first motor and the first transmission component. Figure 4 An example can be the bottom view of the curtain device 10, Figure 5 and an example can be the left view of the curtain device 10. In Figure 4 some components of the curtain device 10 are not shown, such as the counterweight mechanism 500, the bracket 101, etc.

[0126] Exemplarily, as Figure 4 and Figure 5As shown, part or all of the main curtain 200 and the extended curtains 300 and 400 can be wound around their respective winding rollers (110, 120, 130). The winding roller 110 can be fixedly connected to the output shaft of the motor 140. The transmission shaft 151 can pass through the winding rollers 120 and 130 and be in transmission connection with the winding rollers 120 and 130 through splines. The transmission assembly 150 including the transmission component 152 and the transmission rod 151 can be in transmission connection with the motor 140 and the transmission rollers 120 and 130. The transmission component 152 can include gears 153, 154 and a belt mechanism 155. The gear 153 can be fixedly arranged on or coupled to the transmission rod 151, and the gear 154 meshes with the gear 153. The belt mechanism 155 can transmit the transmission shaft provided with the gear 154 to the output shaft of the motor 140. In this scenario, the motor 140 can be an example of the first motor, the winding roller 110 corresponds to the first winding roller, and the winding rollers 120 and 130 correspond to the second winding rollers. The transmission assembly 150 can be an example of the first transmission assembly, the transmission component 152 can be an example of the second transmission assembly, and the transmission rod 151 can be an example of the first transmission rod.

[0127] In one embodiment, the reduction ratio of the belt mechanism 155 is the reciprocal of the reduction ratio of the reduction mechanism formed by the gears 154 and 153. For example, the belt mechanism 155 can include belt pulleys respectively arranged on the sides of the motor 140 and the gear 154, and the diameters of the two belt pulleys can be the same; the number of teeth of the gears 153 and 154 can be the same. In this scenario, the reduction ratio of the belt mechanism 155 is 1, and the reduction ratio of the gears 153 and 154 is also 1. In some other examples, the reduction ratio of the belt mechanism 155 can be other values, such as 2, 1.5, etc.

[0128] In the embodiments of the present application, when the motor 140 drives the transmission shaft 151 through the transmission component 152, the rotational speed of the transmission shaft 151 is the same as that of the output shaft of the motor 140 and the rotation direction is opposite. That is to say, the transmission assembly 150 can make the rotational speeds of the winding rollers of the main curtain 200 and the extended curtains (300, 400) the same and the rotation directions opposite. Through this transmission mechanism, the two winding rollers rotate in opposite directions, so that the main curtain and the extended curtains can be arranged in the middle of the two winding rollers, making the structure more compact. At the same time, the gap between the main curtain and the extended curtains can be reduced, providing a more flat and integrated visual effect. In this way, the moving speeds of the main curtain 200 and the extended curtains 300 and 400 in the first direction can be made the same.

[0129] In some embodiments, different from Figure 4 the manner shown, the winding rollers of the main curtain and the extended curtains can be arranged on the same side of the winding mechanism. The transmission form and structure of the transmission assembly 150 can be adjusted according to actual needs.

[0130] In some possible implementation manners, the rewinding mechanism 100 may further include a first guiding member and a second guiding member, and the gap between the first guiding member and the second guiding member is less than or equal to a first threshold value. The main curtain 200 extended from the winding roller 110 of the main curtain and the extended curtains (300, 400) extended from the winding rollers (120, 130) of the extended curtains pass through the gap (referred to as the first gap) between the first guiding member and the second guiding member and then unfold along a first direction.

[0131] In some possible implementation manners, the rewinding mechanism 100 may further include a third guiding member and a fourth guiding member, and a first guiding surface of the third guiding member and a second guiding surface of the fourth guiding member are arranged in parallel. The main curtain 200 extended from the winding roller 110 of the main curtain passes through the first gap after being guided by the first guiding surface, and the extended curtains (300, 400) extended from the winding rollers (120, 130) of the extended curtains pass through the first gap after being guided by the second guiding surface.

[0132] Exemplarily, the first guiding member to the fourth guiding member may be respectively independent members. Alternatively, some or all of the first guiding member to the fourth guiding member may be coupled to the same member. For example, some or all of the first guiding member to the fourth guiding member may be coupled to the bracket 101. That is to say, some structures of the bracket 101 may correspond to some or all of the first guiding member to the fourth guiding member.

[0133] In one embodiment, as Figure 5 shown, the rewinding mechanism 100 includes guiding members 102 and 103. The curtains (200, 300, 400) may pass through the gap formed by the sides of the guiding members 102 and 103 and extend in the vertical direction. This gap may correspond to the first gap. For example, the first threshold value may be less than or equal to 5 mm or 8 mm. Additionally, the first threshold value may be set according to the thickness of the main curtain and the thickness of the extended curtain. For instance, the first threshold value may be equal to the sum of the thickness of the main curtain, the thickness of the extended curtain, and a preset value (such as 1 mm, 2 mm, etc.). In this scenario, the guiding members 102 and 103 may respectively correspond to the first guiding member and the second guiding member.

[0134] In the embodiments of the present application, the gap between the first guiding member and the second guiding member is less than or equal to the first threshold value, which can enable different curtains to maintain a gap as small as possible in the projection direction of the curtain device, so as to improve the quality feeling of the curtain device.

[0135] In another embodiment, as Figure 5As shown, the upper surfaces of the guiding members 102 and 103 are parallel. After the main curtain 200 extended from the winding roller 110 passes through the upper surface of the guiding member 102, it passes through the gap between the guiding members 102 and 103. For example, the upper surfaces of the guiding members 102 and 103 can be in the same plane. The guiding members 102 and 103 can respectively correspond to the third guiding member and the fourth guiding member, and their upper surfaces can respectively correspond to the first guiding surface and the second guiding surface.

[0136] In another embodiment, the guiding member 102 can be coupled to the guiding member 103.

[0137] Since the main curtain 200 and the extended curtains (300, 400) are respectively wound around their own winding rollers, when the winding rollers (110, 120, 130) rotate to deploy or retract the curtains (200, 300, 400), the outer diameter of the rotating assembly formed by the curtains (200, 300, 400) and their winding rollers (110, 120, 130) will change, which may cause the deployment speeds of different curtains in the first direction to be different. In the embodiments of the present application, by providing the third guiding member and the fourth guiding member, it is beneficial for different curtains to maintain the same motion state in the first direction.

[0138] In some possible implementation manners, the winding mechanism 100 can further include a second motor and a third transmission assembly. The third transmission assembly is used to transmission-connect the winding rollers (120, 130) of the extended curtains to the second motor, so that the second motor drives the winding rollers (120, 130) of the extended curtains to move in the second direction. For example, the third transmission assembly can adopt transmission methods such as belt transmission, gear transmission, chain transmission, screw transmission, and compound transmission.

[0139] In one embodiment, the winding mechanism 100 can include a plurality of second motors to respectively drive the extended curtains 300 and 400 to move in the second direction. Correspondingly, the winding mechanism 100 can include a plurality of third transmission assemblies. For example, in the case of the curtain arrangement shown in (b) in Figure 1 corresponding second motors can be provided for the extended curtains 300 and 400 respectively.

[0140] In another embodiment, one second motor can be used to simultaneously drive the extended curtains 300 and 400 to move in the second direction. By this means, only one set of transmission components can be used to achieve the effect of simultaneously driving the winding rollers 120 and 130 to move in the second direction, which can reduce the number of parts in the winding mechanism, improve the assembly speed of the curtain device, and reduce the cost of the curtain device.

[0141] In some possible implementations, the third transmission assembly may include a second transmission rod extending in the second direction, a base for setting the winding roller of the extended curtain, and a fourth transmission assembly. The base may be provided with a first through hole and a second through hole. The first transmission rod may be disposed through the first through hole, and the first transmission rod can freely rotate around the second direction within the first through hole. The second transmission rod may be disposed through the second through hole and is in transmission connection with the base. The base is fixedly connected to the winding roller of the extended curtain in the second direction, and the winding roller of the extended curtain and the base can rotate relative to the first transmission rod. The fourth transmission assembly is used to transmission-connect the second transmission rod to the second motor so that the second motor drives the second transmission rod to rotate. For example, the fourth transmission assembly may adopt transmission methods such as belt transmission, chain transmission, gear transmission, and compound transmission. Another example is that the second transmission rod may be a worm or a screw.

[0142] Exemplarily, as Figure 4 shown, for the extended curtain 400, the transmission assembly 170 can transmission-connect the winding roller 130 and the motor 160. When the motor 160 rotates, it can drive the winding roller 130 to move in the second direction through the transmission assembly 170. The transmission assembly 170 may include a transmission rod 171, a belt mechanism 172 that transmission-connects the motor 160 and the transmission rod 171, and a base 174 that is in transmission connection with the transmission rod 171. The winding roller 130 is disposed on the base 174 and can axially rotate around the second direction relative to the base 174. In this scenario, the motor 160 may correspond to the second motor, the transmission assembly 170 may be taken as an example of the third transmission assembly, the transmission rod 171 may correspond to the second transmission rod, and the belt mechanism 172 may be taken as an example of the fourth transmission assembly.

[0143] For the extended curtain 300, the winding roller 120 is disposed on the base 173 and can axially rotate around the second direction relative to the base 173. Similar to the base 174, the base 173 is in transmission connection with the transmission rod 171. When the motor 160 rotates, it can drive the transmission rod 171 to rotate through the belt mechanism 172; when the transmission rod 171 rotates, it can drive the base 173 to move in the second direction. In this scenario, the transmission assembly composed of the transmission rod 172, the belt mechanism 172, and the base 173 may be taken as an example of the third transmission assembly.

[0144] In one embodiment, the bracket 101 may be provided with a bracket for supporting the transmission rod 171. A through hole is provided on this bracket, and the transmission rod 171 may be disposed through this through hole. The transmission rod 171 and the through hole of this bracket may form a rotating pair.

[0145] In some possible implementations, the bases 173 and 174 and the transmission rod 171 adopt screw transmission. The directions of the threads on both sides of the transmission rod 171 are opposite, so that the transmission rod 171 can drive the bases 173 and 174 to move along different sub-directions of the second direction when rotating. For example, they move along the left and right sides in the horizontal direction respectively.

[0146] Assume that the transmission rod 171 is a threaded rod. Taking the extended curtain 300 as an example, the way the motor 160 drives the winding roller 120 will be introduced in combination with Figure 6 the description. Figure 6 It can be understood as a cross-sectional view of a certain section of the base 173.

[0147] As Figure 6 shown, the base 173 can be provided with a through hole 1731, and the transmission rod 151 can pass through the through hole 1731; when the transmission rod 151 is in the through hole 1731, it can rotate freely in its axial direction. For example, the through hole 1731 can be circular, and its diameter can be larger than the maximum axial dimension of the transmission rod 151.

[0148] The base 173 can be provided with a boss 1732, and the winding roller 120 is provided with a limiting cavity 121. The boss 1732 can be engaged with the limiting cavity 121, so that the base 173 and the winding roller 120 are fixedly connected in the second direction. At this engaging position, the boss 1732 and the cavity 121 can form a rotating pair, so that the winding roller 120 can rotate axially relative to the base 173 in the second direction. For example, the through hole 1731 can be arranged at the center of the boss 1732; it can extend along the axial direction of the boss 1732.

[0149] The base 173 can be provided with a threaded hole 1733. The transmission rod 171 can be arranged in the threaded hole 1733 and is in screw transmission with the threaded hole 1733. The axis of the threaded hole 1733 can be parallel to the second direction.

[0150] In one embodiment, when the motor 160 works, it drives the transmission rod 171 to rotate through the belt mechanism 172. When the transmission rod 171 rotates, the base 120 moves along the second direction on the transmission rod 151. Since the winding roller 120 of the extended curtain 300 is fixed to the base 173, when the base 173 moves along the second direction, it drives the winding roller 120 to move along the second direction on the transmission rod 120. Through this method, the curtain device 10 can realize the change between the first unfolded state and the second unfolded state.

[0151] In the embodiment of the present application, the base can support the winding roller of the extended curtain, can not interfere with the rotation of the winding roller of the extended curtain, and can also drive the winding roller of the extended curtain to move horizontally. Through this method, the design difficulty of the transmission component can be reduced, the number of parts in the winding mechanism can be reduced, and the cost can be reduced.

[0152] In some possible implementation manners, in order to avoid the shaking of the counterweight mechanism 500, the curtain device 10 further includes a bracket disposed between the winding mechanism 100 and the counterweight mechanism 500. For example, as Figure 7 shown in the brackets 600 and 700. Figure 7 This can be an example of the rear view of the curtain device 10.

[0153] Exemplarily, the brackets (600, 700) may include a first connecting member and a second connecting member. One end of the first connecting member may be hinged to one end of the second connecting member. The other end of the first connecting member may be disposed on the winding mechanism, and the other end of the second connecting member may be disposed on the counterweight mechanism. For example, the first connecting member may be hinged to the winding mechanism; the second connecting member may be hinged to the counterweight mechanism.

[0154] Taking the bracket 600 as an example hereinafter, in combination with Figure 8 introduce the setting on the bracket 600. Figure 8 This can be an example of the exploded view of the bracket 600. Figure 8 Some components of the bracket 600 in are optional. For example, the elastic component 630, the transmission mechanisms 640 and 650.

[0155] In one embodiment, taking the bracket 600 as an example, as Figure 8 shown, the bracket 600 may include connecting members 610 and 620. The top of the connecting member 610 may be disposed on the winding mechanism 100 and form a rotating pair with the winding mechanism 100. The bottom of the connecting member 610 may be disposed on the connecting member 620 and form a rotating pair. The other end of the connecting member 620 may be disposed on the counterweight mechanism 500 and form a rotating pair with the counterweight mechanism 500. For example, the rotation axis of the above rotating pair may be set along the projection direction of the curtain device 10, the third direction.

[0156] In an actual scenario, the user may accidentally touch the counterweight mechanism 500. Such external interference may cause the curtain body of the curtain device 10 and the counterweight mechanism 500 to shake. In the embodiments of the present application, by providing the brackets 600 and 700, the curtain device 10 can resist such external interference, which is beneficial to maintaining the shape of the curtain body.

[0157] In some possible implementation manners, the brackets (600, 700) may further include an elastic component. One end of the elastic component may be disposed on the first connecting member, and the other end of the elastic component may be disposed on the second connecting member. When the curtain device 10 is in the retracted state, the elastic component is in a stretched state.

[0158] In one embodiment, as Figure 8As shown, the bracket 600 may further include an elastic component 630. Cavities may be provided in the connecting members 610 and 620, and the elastic component 630 may be disposed in the cavities to prevent the elastic component 630 from affecting the aesthetics of the external shaping surface of the bracket 600. As Figure 8 shown, the elastic component 630 may include a connecting rod 631 and a spring 632. One end of the spring 632 is disposed on the connecting member 620, and the other end is disposed on the connecting rod 631; the other end of the connecting rod 631 is disposed on the connecting member 610; the connecting rod 631 may extend along the contour directions of the connecting members 610 and 620.

[0159] During the process of the curtain device 10 being unfolded from the retracted state to the first unfolded state, for the bracket 600, the angle between the connecting members 610 and 620 gradually increases, and the deformation amount of the elastic component 630 gradually decreases. That is to say, under the action of the elastic connection component 630, the connecting members 610 and 620 tend to open.

[0160] In an actual scenario, the user may accidentally touch the counterweight mechanism 500, and such external interference may cause the counterweight mechanism 500 to move in the first direction, affecting the shape of the curtain main body. In the embodiments of the present application, by providing the elastic connection component 630, the bracket 600 can resist such external interference, which is beneficial to maintaining the shape of the curtain main body and is also beneficial to reducing the weight of the counterweight mechanism 500.

[0161] As described above, through the second motor and the third transmission component, the movement of the second winding rollers (120, 130) in the second direction can be driven, and then the extended curtains (300, 400) can be driven to move in the second direction. However, since the curtain usually uses a flexible material, the part of the extended curtain 300 on the side of the counterweight mechanism 500 (for example, the lower half of the extended curtain 300) may be difficult to move along the second direction following the second winding rollers (120, 130).

[0162] Exemplarily, the counterweight mechanism 500 may be provided with a first curtain bracket fixedly connected to the bottom of the extended curtain. By driving the first curtain bracket to move in the horizontal direction, the bottom of the extended curtain can be driven to move in the horizontal direction.

[0163] In this way, even if the curtain uses a flexible material, by controlling the winding rollers of the extended curtain and the first curtain bracket to move in the horizontal direction, the top and bottom of the extended curtain can be respectively driven to move in the horizontal direction, and the posture of the extended curtain can be maintained.

[0164] In some possible implementation manners, the counterweight mechanism 500 may include a motor and a transmission component that transmission-connects the first curtain bracket to the motor. That is to say, the bottom of the extended curtain can be driven to move in the horizontal direction by the motor provided in the counterweight mechanism 500.

[0165] Since setting a motor in the counterweight mechanism 500 may cause an increase in the volume and weight of the counterweight mechanism 500, in some possible implementation manners, a transmission mechanism may be set on the brackets (600, 700). The motor disposed on the winding mechanism 100 can drive the transmission mechanism, and then drive the first curtain bracket to move in the horizontal direction.

[0166] Exemplarily, the transmission mechanism may include: a first universal joint disposed on the winding mechanism, a second universal joint disposed on the counterweight mechanism, and a fifth transmission component for transmission-connecting the second universal joint to the first universal joint. The winding mechanism 100 may further include a transmission component for transmission-connecting the first universal joint to the corresponding motor.

[0167] Since the movement of the winding rollers (120, 130) of the extended curtain in the horizontal direction is driven by the second motor, when using a motor other than the second motor to drive the first curtain bracket to move in the horizontal direction, a high control precision of the motor is required, resulting in an increase in the cost of the curtain device 10.

[0168] In some possible implementation manners, the winding mechanism 100 may include a sixth transmission component, and the sixth transmission component may be used for transmission-connecting the first universal joint to the second motor to enable the second motor to drive the first universal joint to rotate. The counterweight mechanism may include a seventh transmission component, and the seventh transmission component may be used for transmission-connecting the first curtain bracket to the second universal joint to convert the rotation of the second universal joint into the movement of the first curtain bracket in the second direction. For example, the sixth transmission component and the seventh transmission component may adopt transmission manners such as gear transmission, belt transmission, chain transmission, worm and worm gear transmission, and compound transmission. The embodiments of the present application do not limit this.

[0169] Exemplarily, since the second motor can drive the base of the winding roller of the extended curtain to move, in order to reduce the number of components in the winding mechanism 100, the sixth transmission component may transmission-connect the first universal joint to the base to convert the movement of the base in the second direction into the rotation of the first universal joint. In this way, the first universal joint can be transmission-connected to the second motor.

[0170] In an actual scenario, the curtain usually adopts a flexible material. Only driving the winding roller of the extended curtain to move in the horizontal direction may only be able to drive the top of the extended curtain to move in the horizontal direction, and it is difficult to effectively drive the bottom of the extended curtain to move in the horizontal direction. Moreover, directly setting a motor for driving the bottom of the extended curtain to move in the horizontal direction in the counterweight mechanism will cause an increase in the weight of the counterweight mechanism. In addition, when using different motors to drive the top and bottom of the extended curtain to move in the second direction respectively, a relatively high motor control precision may be required.

[0171] In the embodiments of the present application, by arranging a transmission mechanism on the bracket, the second motor can drive the top and bottom of the extended curtain to move horizontally along corresponding transmission paths, which can effectively maintain the posture of the extended curtain with relatively low control precision, and is beneficial to improving the quality sense of the product.

[0172] Taking the bracket 600 as an example below, in combination with Figure 8 , a transmission mechanism arranged on the bracket and capable of enabling the second motor to drive the bottom of the extended curtains (300, 400) will be introduced.

[0173] Exemplarily, the bracket 600 may include a transmission mechanism 640. The transmission mechanism 640 may include universal joints 641, 642, 643, a connecting member 644 disposed between the universal joints 641 and 643, and a connecting member 645 disposed between the universal joints 642 and 643. The universal joint 641 is disposed on the winding mechanism 100, the universal joint 642 is disposed on the counterweight mechanism 500, and the universal joint 643 is disposed at the connection of the connecting members 610 and 620. In this embodiment, the universal joint 641 may correspond to the first universal joint; the universal joint 642 may correspond to the second universal joint; the transmission assembly composed of the universal joint 643, the connecting members 644 and 645 may correspond to the fifth transmission assembly.

[0174] The connecting members 610, 620 may be provided with cavities, and the transmission mechanism 640 may be disposed in the cavities. However, since it is difficult for the two ends of the universal joint 643 to be completely fitted, when the curtain device 10 is wound up, the bracket provided with the transmission mechanism 640 is difficult to be completely folded. There will be a large gap between the top and bottom of the bracket, and a relatively large storage space needs to be provided in the winding mechanism to enable the counterweight mechanism 500 to fit with the winding mechanism 100, and even there may be a large gap between the counterweight mechanism 500 and the winding mechanism 100 in the vertical direction.

[0175] Through the transmission member with multiple universal joints, the power of the motor can be transmitted to the lower part of the bracket 600, so that the whole bracket has power up and down, thereby improving the smoothness of the horizontal movement of the bracket, and avoiding uneven stress up and down when the motor drags the whole bracket at the upper part, which may cause blockage and even deformation of the bracket.

[0176] In some possible implementations, the fifth transmission assembly may include a third universal joint and a fourth universal joint disposed around the hinge portion of the first connecting member and the second connecting member. The fourth universal joint is in transmission connection with the third universal joint. The fifth transmission assembly may further include: a first connecting assembly extending along a first axis, the first connecting assembly may include a third connecting member and a fourth connecting member, the third connecting member and the fourth member are capable of relatively moving along the first axis, and the fourth connecting member is configured to transmit the axial rotation of the third connecting member along the first axis to the outside of the connecting assembly. The first connecting assembly may be disposed between the first universal joint and the third universal joint, or disposed between the fourth universal joint and the second universal joint.

[0177] Exemplarily, the bracket 600 may include a transmission mechanism 650. The transmission mechanism 650 may include universal joints 651, 652, 653, and 654, a connecting assembly 655 disposed between the universal joints 651 and 653, and a connecting rod 658 disposed between the universal joints 652 and 654. The functions of the universal joints 651 and 652 are similar to those of the universal joints 641 and 642.

[0178] The universal joints 653 and 654 may be disposed around the hinge portion of the connecting members 610 and 620. For example, a connecting rod may be disposed between the universal joints 653 and 654. Also for example, the universal joints 653 and 654 may share the same universal joint fork, as Figure 8 shown.

[0179] The connecting assembly 655 may include connecting rods 656 and 657. For example, as Figure 8 shown, the connecting rod 656 may be provided with a groove, and the connecting rod 657 is provided with a protrusion that cooperates with the groove, and the protrusion may slide within the groove. When the connecting rod 656 rotates about its axis, through the cooperation mechanism of the groove and the protrusion, the connecting rod 657 can be driven to rotate.

[0180] For the transmission mechanism 650, the universal joints 651 and 652 may respectively correspond to the first universal joint and the second universal joint. The transmission assembly formed by the connecting assembly 655, the universal joints 653 and 654, and the connecting rod 658 may correspond to the fifth transmission assembly. The universal joint 653 may correspond to the third universal joint; the universal joint 654 may correspond to the fourth universal joint. The connecting assembly 655 may correspond to the first connecting assembly, the connecting rod 656 may correspond to the third connecting member, and the connecting member 657 may correspond to the fourth connecting member.

[0181] In one embodiment, the transmission members 610 and 620 may be provided with cavities along their respective extending directions, and the transmission mechanism 640 or 650 may be disposed through the cavities of the transmission members 610 and 620.

[0182] In the embodiments of the present application, by providing a plurality of universal joints and a first connection component, the transmission mechanism can occupy a smaller space in the first direction after folding, enabling the counterweight mechanism and the winding mechanism to fit together in the retracted state.

[0183] In some possible implementation manners, the sixth transmission component may include a belt fixedly arranged with the base, and the belt may be in transmission connection with the first universal joint; and / or, the seventh transmission component may include a rack arranged on the first curtain bracket and a gear arranged on the second universal joint.

[0184] Exemplarily, taking the transmission mechanism 650 as an example, in combination with Figure 9 、 Figure 10 briefly introduce the working mode of the transmission mechanism arranged on the bracket 600.

[0185] As Figure 9 shown, the belt 180 is fixed to the base 173, and one end of the belt is in transmission connection with the universal joint 651. When the base 180 moves in the second direction, it can drive the belt 180 to rotate around its pulley. One of the pulleys of the belt 180 may be arranged on the universal joint 651, or may be a universal joint fork of the universal joint 651. When the belt 180 rotates, it can drive the universal joint 651 to rotate. When the universal joint 651 rotates, it can drive the universal joint 652 to rotate through the connection component 655, universal joints 653, 654 and the connecting rod 658. In this embodiment, the belt mechanism where the belt 180 is located may correspond to the sixth transmission component.

[0186] As Figure 10 shown, the transmission component 511 composed of the gear 512 and the rack 513 can be in transmission connection with the universal joint 652 and the curtain bracket 510. The gear 512 may be arranged on the universal joint 652, and the rack 513 may be arranged on the curtain bracket 510. When the universal joint 652 rotates, it can drive the curtain bracket 510 to move horizontally through the transmission component 511. In this embodiment, the transmission component 511 may correspond to the seventh transmission component.

[0187] In some possible implementation manners, the winding mechanism 100 may further include a first limiting member, and the first limiting member may be used for: when the curtain device switches between the retracted state and the first unfolded state, restricting the rotation of the first universal joint; and / or, the counterweight mechanism 500 may further include a second limiting member, and the second limiting member may be used for: when the curtain device switches between the retracted state and the first unfolded state, restricting the rotation of the second universal joint.

[0188] Exemplarily, taking the transmission mechanism 650 as an example, introduce the working mode of the first limiting member.

[0189] In one embodiment, as Figure 11As shown, the universal joint 651 can be a cardan joint, and the winding mechanism 100 can include a limiting member 104. The winding mechanism 100 includes a limiting member 104 disposed on the bracket 101, and the limiting member 104 can be driven by a motor to slide along the second direction. The limiting member 104 is provided with a groove that cooperates with the cross shaft of the universal joint 651. When the limiting member 104 is in the limiting state, the rotation of the cross shaft can be restricted through the groove, so as to achieve the effect of restricting the rotation of the universal joint 651. In this scenario, the limiting member 104 can correspond to the first limiting member.

[0190] In another embodiment, the universal joint 651 can be provided with a pin hole, and the winding mechanism 100 can be provided with a pin that can slide and cooperate with the pin hole. The rotation of the universal joint 651 can be restricted by the pin. In this embodiment, the pin can correspond to the first limiting member.

[0191] Exemplarily, the limiting manner of the second limiting member can be the same as that of the first limiting member.

[0192] In some possible implementation manners, when the curtain device 10 is in the first unfolding state or the second unfolding state, the main curtain is in the first posture. The winding mechanism 100 can further include a third limiting member, and / or, the counterweight mechanism 500 can further include a fourth limiting member. The third limiting member can be used to: when the main curtain is in the first posture, restrict the relative rotation between the first connecting member and the winding mechanism. The fourth limiting member can be used to: when the main curtain is in the first posture, restrict the relative rotation between the second connecting member and the counterweight mechanism.

[0193] Exemplarily, taking the bracket 600 as an example, the working manner of the third limiting member is introduced.

[0194] In one embodiment, as Figure 12 shown, the connecting member 610 is hinged to the bracket 101, and the connecting member 610 can be provided with a protrusion 611. The winding mechanism 100 includes a limiting member 105 disposed on the bracket 101, and the limiting member 105 can be driven by a motor to slide along the second direction. When the limiting member 105 is in the limiting state, it can restrict the rotation of the connecting member 610 by restricting the rotation of the protrusion 611. In this scenario, the limiting member 105 can correspond to the third limiting member.

[0195] In another embodiment, the connecting member 610 can be provided with a pin hole, and the winding mechanism 100 can be provided with a pin that can slide and cooperate with the pin hole. In this embodiment, the pin can correspond to the third limiting member.

[0196] Exemplarily, the limiting manner of the fourth limiting member can be the same as that of the third limiting member.

[0197] In some embodiments, other methods may be adopted to limit the rotation of the first universal joint, the second universal joint, the first connecting member, and the second connecting member, which are not limited in the embodiments of the present application.

[0198] In some possible implementation manners, the extended curtains 300 and 400 may not be regular shapes. For example, in the unfolded state, the width at the top of the extended curtains 300 and 400 may be smaller than the width at the bottom. Since the curtain is usually made of a flexible material, in the second unfolded state, the outer contour of the extended curtains 300 and 400 may present an unexpected state. For example, the outer contour of the extended curtain may present a corrugated shape.

[0199] Exemplarily, the extended curtains 300 and 400 may be provided with one or more support bars arranged in the horizontal direction.

[0200] The above Figures 1 to 12 The embodiments are introduced to describe the curtain device provided by the embodiments of the present application. The following Figure 13 is introduced to describe the control method provided by the embodiments of the present application. Among them, the content not described in detail can be referred to the embodiments of the curtain device above.

[0201] Exemplarily, Figure 13 is a schematic flowchart of a control method provided by an embodiment of the present application. This method 800 may be executed by the control device of the curtain device 10, or may be executed by a component of the control device (such as a processor, a processing circuit, a chip, etc.), or may be executed by a cockpit or a vehicle provided with the control device, which is not limited in the embodiments of the present application. This method 800 may include:

[0202] S810, obtain control information, where the control information indicates the target state of the curtain device.

[0203] Exemplarily, the target state of the curtain device 10 may include a retracted state, a first unfolded state, or a second unfolded state.

[0204] For the description of the curtain device 10, reference may be made to Figures 1 to 12 the relevant embodiments described above, and details are not described herein again.

[0205] S820, according to the control information, control the curtain device to be in the target state.

[0206] In some possible implementation manners, the current state of the curtain device may be one of the retracted state and the first unfolded state, and the target state may be the other of the retracted state and the first unfolded state. Controlling the curtain device to be in the target state according to the control information may include: according to the control information, controlling the driving motor for driving the winding roller of the main curtain to rotate, and controlling the driving motor for driving the winding roller of the extended curtain to rotate.

[0207] Exemplarily, the drive motors for driving the winding rollers of the main curtain and the extension curtain to rotate are both the first motor. For example, the winding mechanism 100 is provided with a transmission assembly 150 and a motor 140. Controlling the curtain device to be in the target state according to the control information may include: controlling the first motor to rotate according to the control information.

[0208] In some possible implementation manners, the current state of the curtain device may be one of a first unfolded state and a second unfolded state, and the target state is the other of the first unfolded state and the second unfolded state. Controlling the curtain device to be in the target state according to the control information may include: controlling the second motor to rotate according to the control information.

[0209] In some possible implementation manners, when the first motor rotates in the first driving direction, the main curtain and the extension curtain are unfolded in the first direction. When the first motor rotates in the second driving direction, the main curtain and the extension curtain are retracted in the first direction. The method may further include: before the second motor rotates, controlling the first motor to rotate a first preset angle in the first driving direction; after the second motor stops rotating, controlling the first motor to rotate a second preset angle in the second driving direction. For example, the first preset angle may be 10 degrees, 15 degrees, or may be other values, such as 30 degrees, etc. Also, for example, the second preset angle may be the same as the first preset angle or different from the first preset angle. The second preset angle may be 10 degrees, 15 degrees, or may be other values, such as 30 degrees, etc.

[0210] Exemplarily, when the curtain device 10 is in the first unfolded state, the main curtain and the extension curtain may be in a tensioned state. When the user instructs to control the curtain device 10 to switch to the second unfolded state, there will be a relatively large resistance when directly controlling the second motor to rotate. The motor 140 may be first controlled to rotate a preset angle in the driving direction 1, so that the main curtain and the extension curtain are further unfolded in the first direction. By this way, the main curtain and the extension curtain can be changed from the tensioned state to the relaxed state. Then, the motor 160 is controlled to rotate, driving the extension curtain to move horizontally to the attitude corresponding to the second unfolded state. Then, the motor 140 is controlled to rotate in the opposite direction of the driving direction 1, so that the main curtain and the extension curtain are changed from the relaxed state to the tensioned state.

[0211] In some possible implementation manners, the method may further include: when the main curtain is in the first attitude, controlling the third limiting member to be in the first position to limit the relative rotation between the first connecting member and the winding mechanism; and / or when the main curtain is in the first attitude, controlling the fourth limiting member to be in the second position to limit the relative rotation between the second connecting member and the counterweight mechanism.

[0212] In one embodiment, asFigure 12 As shown, the position where the limiting member 105 is located can correspond to the first position.

[0213] In some possible implementation manners, the method may further include: when the curtain device switches between the retracted state and the first deployed state, controlling the first limiting member to be in the third position to limit the rotation of the first universal joint; and / or when the curtain device switches between the retracted state and the first deployed state, controlling the second limiting member to be in the fourth position to limit the rotation of the second universal joint.

[0214] In one embodiment, as Figure 11 shown, the position where the limiting member 104 is located can correspond to the third position.

[0215] The above combines Figure 13 to introduce the control method provided by the embodiments of the present application. Next, the control device provided by the embodiments of the present application will be described in conjunction with Figure 14 and Figure 15 . The description of the control device embodiments corresponds to the description of the method embodiments. Therefore, the content not described in detail can be referred to the above method embodiments.

[0216] Exemplarily, Figure 14 shows a schematic block diagram of a control device (hereinafter referred to as device 2000) provided by an embodiment of the present application. The device 2000 may include units for executing Figure 13 the method in, and each unit in the device 2000 may be used to execute the corresponding process in the method embodiment of Figure 13 above.

[0217] Exemplarily, the device 2000 may include an acquisition unit 2010 and a processing unit 2020. When the device 2000 is used to execute Figure 13 the method 800 in, the acquisition unit 2010 may be used to execute step S810 in the method 800, and the processing unit 2020 may be used to execute step S820 in the method 800.

[0218] Specifically, the acquisition unit 2010 may be used to: acquire control information, and the control information indicates the target state of the curtain device. The processing unit 2020 may be used to control the curtain device to be in the target state according to the control information.

[0219] In some possible implementation manners, the current state of the curtain device may be one of the retracted state and the first deployed state, and the target state may be the other of the retracted state and the first deployed state. The drive motor for driving the winding roller of the main curtain to rotate and the drive motor for driving the winding roller of the extended curtain to rotate are both the first motor. The processing unit 2020 may be used to: control the first motor to rotate according to the control information.

[0220] In some possible implementation manners, the current state of the curtain device may be one of a first unfolding state and a second unfolding state, and the target state is the other of the first unfolding state and the second unfolding state. The processing unit 2020 may be configured to: control the second motor to rotate according to the control information.
