Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a sunshade device and a vehicle. Background Technology

[0002] In hot weather, if a vehicle is parked outdoors, the sun will shine directly into the vehicle's interior through the windshield. This not only reduces the lifespan of the vehicle's interior due to sun exposure, but also causes the interior temperature to soar, resulting in high surface temperatures for the dashboard, steering wheel, and seats, which seriously affects the comfort of using the vehicle. Summary of the Invention

[0003] Therefore, embodiments of this application provide a sunshade device and a vehicle to prevent direct sunlight from shining into the interior of the vehicle when it is parked outdoors.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a sunshade device, including:

[0006] A sunshade curtain, comprising a curtain body and a connecting component, wherein one end of the curtain body is connected to the connecting component, and the connecting component is used for connecting to a vehicle;

[0007] A drive mechanism is connected to the end of the curtain body away from the connecting component. The drive mechanism is used to drive the curtain body to move so that the curtain body switches between an unfolded state and a retracted state.

[0008] A locking mechanism, comprising a first limiting member and a second limiting member, wherein the first limiting member is disposed at the end of the curtain body away from the connecting member, and the second limiting member is disposed on the connecting member; when the curtain body is in the retracted state, the first limiting member and the second limiting member are connected to limit the relative position of the curtain body and the connecting member.

[0009] In the unfolded state, the curtain covers the surface of the vehicle's windshield; in the retracted state, the curtain is located at the lower or upper end of the windshield.

[0010] In one possible implementation of this application, the first limiting member is a magnetic member, and the second limiting member is an electromagnet. When the curtain is in the retracted state, the magnetic member is attracted by the electromagnet.

[0011] In one possible implementation of this application, the driving mechanism includes:

[0012] A connecting rope is connected to the end of the curtain body away from the connecting component;

[0013] A winding shaft, wherein the end of the connecting rope facing away from the curtain body is connected to the winding shaft;

[0014] An electric motor is used to drive the winding shaft to rotate, so as to loosen or tighten the connecting rope, thereby switching the curtain between the closed state and the unfolded state.

[0015] A reset component is connected to the sunshade curtain. The reset component is configured to drive the curtain body to deform along a preset trajectory to switch to the retracted state when the motor drives the winding shaft to rotate and loosen the connecting rope.

[0016] In one possible implementation of this application, the connecting rope is a transparent rope.

[0017] In one possible implementation of this application, a connecting rope is connected to each of the opposite sides of the curtain.

[0018] In one possible implementation of this application, the connecting component further includes a roller, and an annular sleeve is provided at the end of the roller and is arranged around the outside of the roller. The roller is connected to the end of the curtain body away from the connecting rope.

[0019] The reset component is a coil spring, which is sleeved on the spool, with one end of the coil spring connected to the annular sleeve and the other end connected to the spool.

[0020] In one possible implementation of this application, the connecting component further includes a housing for connecting to the top of the vehicle's dashboard, the housing having an inlet and outlet, and the reel, the annular sleeve, and the coil spring all located within the housing;

[0021] The roller is rotatably connected to the housing, the annular sleeve is fixedly connected to the housing, and one end of the curtain extends into the housing through the inlet and outlet and is connected to the roller.

[0022] In one possible implementation of this application, a sensor is also included, the sensor being used to acquire at least one of the light intensity and temperature of the environment in which the vehicle is located;

[0023] The electromagnet is configured to de-energize itself when the light intensity or the temperature exceeds a preset value, thereby stopping the attraction of the magnetic component.

[0024] The drive mechanism is configured to drive the curtain to switch from the retracted state to the unfolded state when the light intensity or the temperature is greater than a preset value.

[0025] Secondly, embodiments of this application provide a vehicle, including a vehicle body and a sunshade device as described in any one of the first aspects, wherein the sunshade device is disposed on the vehicle body.

[0026] In one possible implementation of this application, the connecting component of the sunshade device is provided with a first snap-fit ​​member, and the vehicle body is provided with a second snap-fit ​​member. The first snap-fit ​​member and the second snap-fit ​​member engage to fix the connecting component to the vehicle body.

[0027] In the sunshade device and vehicle provided in this application embodiment, the sunshade device includes a sunshade curtain, a drive mechanism, and a locking mechanism. The drive mechanism can drive the curtain body of the sunshade curtain to move, so that the curtain body switches between an unfolded state and a retracted state. In the unfolded state, the curtain body can cover the windshield of the vehicle, preventing sunlight from directly hitting the vehicle interior through the windshield. This prevents the vehicle interior from becoming significantly hot due to direct sunlight when the vehicle is parked outdoors, thus improving the comfort of vehicle use. When the vehicle is in motion, the curtain body is in the retracted state, so it does not obstruct the windshield and does not affect the driver. Visibility; In addition, the second limiting member of the locking mechanism is set on the connecting part of the sunshade, and the first limiting member is set on the end of the curtain away from the connecting part. The connecting part is connected to the vehicle. When the curtain is in the retracted state, the first limiting member and the second limiting member are connected to lock the position of the movable end of the curtain, so that the relative position of the curtain and the connecting part is fixed, preventing the curtain from obstructing the driver's view. Thus, by switching the state of the curtain, it can prevent the interior of the vehicle from being directly exposed to sunlight through the windshield when the vehicle is parked outdoors, and it can also prevent the curtain from obstructing the driver's view when the vehicle is in motion.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0041] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0042] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0043] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0044] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] As mentioned in the background section, when a vehicle is parked outdoors for an extended period, the interior components are exposed to direct sunlight, which significantly reduces their lifespan. Furthermore, in hot weather, direct sunlight from the windshield into the car's interior causes the temperature to spike, resulting in persistently high temperatures on surfaces such as the dashboard, steering wheel, and seats. These components can become unbearably hot to the touch, making the vehicle difficult to use immediately and requiring the air conditioning to cool it down before it can be used normally.

[0046] Based on this, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in the figure, this application provides a sunshade device, including a sunshade curtain 100, a drive mechanism 200 and a locking mechanism 300.

[0047] The sunshade 100 includes a curtain body 110 and a connecting component 120. One end of the curtain body 110 is connected to the connecting component 120, that is, the fixed end of the curtain body 110 is connected to the connecting component 120. The connecting component 120 is used to connect to the vehicle. The drive mechanism 200 is connected to the end of the curtain body 110 away from the connecting component 120, that is, the drive mechanism 200 is connected to the movable end of the curtain body 110. The drive mechanism 200 can drive the movable end of the curtain body 110 to move, so that the curtain body 110 switches between an unfolded state and a retracted state. In the unfolded state, the curtain body 110 covers the surface of the windshield of the vehicle. In the retracted state, the curtain body 110 is located at the lower or upper end of the windshield to avoid affecting the driver's vision.

[0048] For example, the curtain 110 can be a common structure that can be rolled up on a shaft or folded for storage, such as a Venetian blind, a fabric curtain or a plastic curtain, as long as it can switch between the retracted state and the unfolded state under the drive of the drive mechanism 200.

[0049] When the curtain 110 is in the unfolded state, it can cover the windshield to prevent sunlight from directly entering the vehicle through the windshield. Of course, the curtain 110 does not necessarily have to completely block the windshield; only a small portion of the sunlight can enter the vehicle interior, which will not have a significant impact on the interior. To improve the sunshade effect, the shape of the curtain 110 can be the same as or similar to the shape of the windshield.

[0050] The connecting component 120 is typically fixed to the vehicle's dashboard for easy installation and removal. It can be connected to the top of the dashboard using screws or adhesive, for example. Alternatively, the connecting component 120 can be detachably connected to the vehicle, in which case the curtain 110 is in the retracted state, located at the lower end of the windshield. Alternatively, the sunshade can be installed on the outside of the vehicle; however, this may increase drag, requiring removal after each use. In contrast, if installed on the inside of the vehicle, the curtain 110 only needs to be retracted when the vehicle is in motion, without needing to remove the sunshade 100.

[0051] Additionally, when the sunshade is installed inside the vehicle, the connecting component 120 and the curtain 110 can be close to the windshield to reduce its impact on the overhead space of the dashboard.

[0052] The locking mechanism 300 includes a first limiting member 310 and a second limiting member 320. The first limiting member 310 is located at the end of the curtain 110 away from the connecting member 120, that is, the first limiting member 310 is fixed to the movable end of the curtain 110. The second limiting member 320 is located on the connecting member 120. When the curtain 110 is in the closed state, the first limiting member 310 and the second limiting member 320 are connected to limit the relative position of the curtain 110 and the connecting member 120.

[0053] Specifically, after the sunshade is installed on the vehicle, it can prevent sunlight from directly shining into the vehicle interior through the windshield. This prevents the interior temperature from rising significantly due to direct sunlight when the vehicle is parked outdoors, thus improving the comfort of vehicle use. When the vehicle is in motion, the curtain 110 is in the retracted state, so it does not obstruct the windshield and does not affect the driver's vision. In addition, when the curtain 110 is in the retracted state, the first limiting member 310 and the second limiting member 320 are connected to lock the position of the movable end of the curtain 110, so that the relative position of the curtain 110 and the connecting member 120 is fixed, preventing the curtain 110 from shaking and thus preventing the curtain 110 from affecting the driver's vision.

[0054] In some embodiments of this application, the first limiting member 310 is a magnetic member and the second limiting member 320 is an electromagnet. When the curtain 110 is in the retracted state, the magnetic member is attracted by the electromagnet, thereby fixing the relative position between the movable end of the curtain 110 and the connecting member 120, preventing the curtain 110 from shaking or unfolding due to vehicle vibration.

[0055] For example, the magnetic component can be an iron wire disposed at one end of the curtain 110 away from the connecting member 120. The length of the iron wire can be similar to or less than the width of the curtain 110. Of course, the iron wire is along the width direction of the curtain 110. Figure 1 Extending in the X direction, the wire can make the movable end regular in shape, so that the curtain 110 can maintain its shape after being unfolded, thus improving the sunshade effect. On the other hand, the wire is relatively long, so it can be attracted to the electromagnet as soon as it is folded up. The positioning accuracy requirement is low, which makes it easy to achieve automatic locking between the curtain 110 and the connecting part 120.

[0056] For example, the magnetic component can be a plurality of magnetic blocks with magnetic attraction capability, the magnetic blocks are arranged sequentially along the width direction of the curtain 110, and the number of electromagnets is the same as that of the magnetic blocks, and they are arranged one-to-one with the magnetic blocks.

[0057] It should be noted that iron wire can also be made of other materials, such as magnetic steel, nickel, cobalt, or some alloys.

[0058] In some embodiments of this application, the locking mechanism 300 can be a magnetic lock, with its lock body mounted on the connecting member 120 and the latch plate mounted on the movable end of the curtain 110. When the curtain 110 is in the closed state, the lock tongue of the lock body is inserted into the latch plate to restrict the relative position of the curtain 110 and the connecting member 120.

[0059] Of course, a magnetic lock can be selected that locks when the power is off and unlocks when the power is on. That is, the magnetic lock only needs to be powered on each time the curtain 110 needs to be opened, so that its internal coil drives the lock tongue to move and unlock, which helps to save energy.

[0060] In some embodiments of this application, to improve ease of use, the sunshade device may further include a sensor 500, which is used to acquire at least one of the light intensity and temperature of the environment in which the vehicle is located.

[0061] For example, when the vehicle is parked, the sensor 500 can acquire the light intensity. When the light intensity reaches a preset value, the electromagnet is de-energized and loses its magnetism, causing the magnetic attractant to lose its attraction force. At this time, the drive mechanism 200 is activated, driving the movable end of the curtain 110 to move. The curtain 110 changes from a retracted state to an unfolded state, thereby blocking the windshield and preventing sunlight from directly shining into the vehicle interior through the windshield.

[0062] For example, when the vehicle is parked, the sensor 500 can acquire the outside temperature. When the temperature reaches a preset value, the electromagnet is de-energized and loses its magnetism, causing the magnetic component to lose its attraction force. At this time, the drive mechanism 200 is activated, driving the movable end of the curtain 110 to move. The curtain 110 changes from a retracted state to an unfolded state, thereby blocking the windshield and preventing sunlight from directly shining into the vehicle interior through the windshield.

[0063] For example, the sensor 500 simultaneously acquires light intensity and temperature. Once either the light intensity or the temperature reaches a preset value, the electromagnet is de-energized, or the magnetic lock is energized and unlocked, and the drive mechanism 200 drives the curtain 110 to switch to the unfolded state.

[0064] Furthermore, a voice module 400 can be added. When the vehicle is parked, the voice module 400 activates and provides a voice prompt, asking the driver whether to turn on the sunshade. The driver can choose whether to turn on the sunshade based on the weather conditions. If the driver chooses to turn it on, the locking mechanism 300 unlocks, and the drive mechanism 200 moves the movable end of the curtain 110, causing the curtain 110 to switch to the unfolded state for sunshade. If the driver chooses not to turn it on, the sunshade will not activate.

[0065] If the curtain 110 is in the unfolded state, before the vehicle changes from the parked state to the driving state, the voice module 400 will give a voice prompt to ask the driver to close the sunshade to avoid the sunshade from affecting the driver's vision.

[0066] Specifically, the voice module 400, locking mechanism 300, and drive mechanism 200 can all be connected to the vehicle's control system and uniformly controlled by the control system. The control system determines whether the vehicle is in parking mode. When in parking mode, it controls the voice module 400 to provide a voice prompt. Upon receiving the driver's instruction to open the sunshade, it controls the locking mechanism to unlock and controls the drive mechanism 200 to move the curtain 110 to the unfolded state. When the driver starts the vehicle and switches from parking mode to driving mode, the control system determines whether to activate the voice module 400 based on the state of the curtain 110. If the curtain 110 is in the unfolded state, it controls the voice module 400 to provide a voice prompt reminding the driver to close the sunshade. Of course, when the vehicle switches to driving mode, the control system can also automatically control the drive mechanism 200 and locking mechanism 300 to switch the state, causing the curtain 110 to switch to the retracted state and restricting the position of the curtain 110.

[0067] Furthermore, the sensor 500 and the voice module 400 can be used together.

[0068] For example, when the vehicle enters the parking state, the voice prompt module prompts the driver to choose whether to open the sunshade device. If the driver chooses not to open the sunshade device, the sensor 500 does not acquire temperature and light intensity, and the sunshade device does not activate during this parking process unless the driver is given an instruction to activate the sunshade device. If the driver chooses to open the sunshade device, the sensor 500 activates, continuously acquires the outside temperature and light intensity, and sends them to the control system. When the temperature or light intensity reaches a preset value, the control system controls the locking mechanism 300 to unlock and controls the drive mechanism 200 to drive the curtain 110 to switch to the unfolded state.

[0069] For example, when the vehicle enters the parking state, the voice prompt module prompts the driver to choose whether to turn on the sunshade. If the driver chooses not to turn on the sunshade, the sensor 500 is activated to obtain the temperature and light intensity and send them to the control system. When the temperature or light intensity reaches the preset value, the control system controls the locking mechanism 300 to unlock and controls the drive mechanism 200 to drive the curtain 110 to switch to the unfolded state. If the driver chooses to turn on the sunshade, the sensor 500 is not activated, and the control system directly controls the locking mechanism 300 to unlock and controls the drive mechanism 200 to drive the curtain 110 to switch to the unfolded state.

[0070] In some embodiments of this application, the drive mechanism 200 includes a connecting rope 230, a winding shaft 220, a motor 210, and a reset member 240.

[0071] The connecting rope 230 is connected to the end of the curtain 110 away from the connecting component 120, i.e., to the movable end of the curtain 110. The end of the connecting rope 230 away from the curtain 110 is connected to the winding shaft 220. The motor 210 is used to drive the winding shaft 220 to rotate, so as to loosen (the connecting rope 230 is released from the winding shaft 220) or tighten (the connecting rope 230 is wound around the winding shaft 220), so that the curtain 110 switches between the closed state and the open state. The reset member 240 is connected to the sunshade 100. When the motor 210 drives the winding shaft 220 to rotate and loosen the connecting rope 230, the reset member 240 can drive the curtain 110 to deform according to a preset trajectory to switch to the closed state.

[0072] Taking the connecting component 120 fixed to the top of the dashboard as an example, the motor 210 can be fixed to the dashboard or to a position near the roof. When the motor 210 is fixed to a position near the roof, the connecting rope 230 simply hangs down from the roof to hold the movable end of the curtain 110. When the motor 210 is fixed to the dashboard, a pulley can be added to the top of the vehicle for guidance, so that one end of the connecting rope 230 is connected to the movable end of the curtain 110, and the other end passes around the pulley and is connected to the winding shaft 220.

[0073] In use, the motor 210 rotates, causing the winding shaft 220 to rotate. The connecting rope 230 is then wound onto the winding shaft 220, which pulls the movable end of the curtain 110 upward, causing the curtain 110 to unfold. When it is necessary to retract the curtain 110, the motor 210 rotates in the opposite direction, releasing the connecting rope 230. The connecting rope 230 no longer pulls on the curtain 110. At this time, the reset component 240 automatically drives the curtain 110 to deform and switch to the retracted state according to a preset trajectory. In this state, the connecting rope 230 can restrict the direction of movement of the curtain 110, and the cooperation between the connecting component 120 and the connecting rope 230 can also prevent the curtain 110 from shaking. In addition, when the curtain 110 is in the retracted state, it is located at the top of the dashboard, which facilitates disassembly and installation and reduces obstruction of the driver's view.

[0074] The connecting rope 230 can be made of transparent rope to reduce the impact on the driver's vision, for example, a transparent thin rope similar to a fishing line can be used.

[0075] Alternatively, two connecting ropes 230 can be provided, each connected to one side of the curtain 110. For example, a wire can be attached to the end face of the curtain 110, roughly the same width as the curtain 110. The two connecting ropes 230 are connected to the ends of the wire, pulling the curtain 110 from both sides and restricting its position, thus improving the limiting effect on the curtain 110. In this case, the winding shaft 220 can be located above the windshield and extend along the width of the vehicle. A motor 210 and the first winding shaft 220 drive the two connecting ropes 230 to move synchronously. Of course, two winding shafts 220 and two motors 210 can also be provided. The two winding shafts 220 are located on both sides of the windshield, and the two motors 210 are connected to the two winding shafts 220 respectively, driving the winding shafts 220 to rotate. The synchronous movement of the two motors 210 can drive the two connecting ropes 230 to unfold the curtain 110.

[0076] Alternatively, the motor 210 and the winding shaft 220 may not be located directly above the curtain 110, but rather at an angle above it. By utilizing the deformable characteristics of the connecting rope 230, the curtain 110 can be moved. In this case, the obstruction of the driver's view by the motor 210 and the winding shaft 220 can be reduced.

[0077] For example, the connecting component 120 also includes a roller 121, with an annular sleeve 122 surrounding the outer side of the roller 121 at one end. The roller 121 is connected to the end of the curtain 110 away from the connecting rope 230. The resetting component 240 is a coil spring, which is sleeved on the roller 121, with one end connected to the annular sleeve 122 and the other end connected to the roller 121.

[0078] When the connecting rope 230 stops pulling the curtain 110, the coil spring resets and pulls the roller 121 to rotate, so that the curtain 110 automatically rolls up onto the roller 121, thus putting the curtain 110 into a closed state. When the motor 210 drives the connecting rope 230 to pull the curtain 110 to unfold, the roller 121 rotates, causing the coil spring to accumulate elastic potential energy.

[0079] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the connecting component 120 also includes a housing 123 for connecting to the top of the vehicle's dashboard.

[0080] The housing 123 has an inlet and outlet. The roller 121, the annular sleeve 122, and the coil spring are all located inside the housing 123. The roller 121 is rotatably connected to the housing 123, and the annular sleeve 122 is fixedly connected to the housing 123. One end of the curtain 110 extends into the housing 123 through the inlet and outlet and is connected to the roller 121. At this time, the electromagnet can be set on the side wall of the inlet and outlet 1231, or in the area adjacent to the inlet and outlet 1231 on the outside of the housing 123. As long as the position and structure of the magnetic component are adjusted accordingly, the magnetic component can be stably attracted to the electromagnet when the curtain 110 is in the closed state.

[0081] When the curtain 110 is in the retracted state, the housing 123 can protect the curtain 110. At the same time, the housing 123 also facilitates connection with the vehicle.

[0082] It should be noted that the connecting component 120 may not include the housing 123. In this case, the roller 121 is directly rotatably connected to the vehicle, and the annular sleeve 122 is fixed on the vehicle.

[0083] For example, guide rails are provided on both sides of the curtain 110 on the vehicle, and guide blocks are added to the curtain 110 that are slidably connected to the guide rails. The reset member 240 can be a high-elasticity band, which is located on both sides of the curtain 110. One end of the high-elasticity band is connected to the connecting member 120, and the high-elasticity band is connected to the guide block. At this time, the curtain 110 is a flexible curtain or Venetian blind made of flexible material. When the curtain 110 is in the unfolded state, the high-elasticity band is in the stretched state and accumulates elastic potential energy. When the connecting rope 230 no longer pulls the curtain 110, the high-elasticity recovery deformation band pulls the guide block to move. At this time, the curtain 110 can move along the guide rails through the guide block and be folded, so that the curtain 110 enters the closed state.

[0084] In some embodiments of this application, the connecting component 120 can be fixed near the top of the vehicle. In this case, the drive mechanism 200 can be a retractor. The curtain 110 can be put into a retracted state or an unfolded state by the forward and reverse rotation of the motor 210.

[0085] This application provides a vehicle, including a vehicle body. It should be noted that the vehicle in this application can refer to a large vehicle, a small vehicle, a special-purpose vehicle, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle includes a windshield, a steering wheel, wheels, a power source, and a transmission system between the wheels and the power source. The transmission system transmits the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0086] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application.
