Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent drive technology, and in particular to a lifting device, system and vehicle. Background Technology
[0002] The seats in a vehicle are designed to provide physical support for occupants and to provide them with safety and comfort while the vehicle is in motion.
[0003] To expand vehicle space and improve comfort, a seat-folding function has been introduced. Seat-folding can be understood as reclining the seat backs forward or backward. For example, folding down the rear seats expands the vehicle's usable space and, combined with the fore-and-aft space of the seats, provides users with a lying-down area, enhancing user comfort.
[0004] Currently, when the seat is folded down, the height of the folded-down surface is different from the height of the space in front of and behind the seat. This results in an uneven surface for users to lie down, which in turn affects the user's driving experience. Summary of the Invention
[0005] This application provides a lifting device, system, and vehicle to eliminate the height difference between the plane after the seat is folded down and the front and rear space planes of the seat, so as to achieve the same or approximately the same height between the plane after the seat is folded down and the front and rear space planes of the seat, thereby improving the user's comfort when using this part of the space.
[0006] In a first aspect, this application provides a lifting device applied to an equipment with a seat reclining function. The lifting device includes a first driver, a lead screw, a first hinge, a platform, and a base. The first hinge includes a first fulcrum, a second fulcrum, a third fulcrum, and a fourth fulcrum. The first fulcrum is connected to the platform, the second fulcrum is connected to the base, and the third and fourth fulcrums are engaged with the lead screw. The base is positioned in the equipment near the seat. The first driver controls the rotation of the lead screw, which, when rotating, causes the third and fourth fulcrums to move in opposite directions. When the third and fourth fulcrums move in opposite directions, the distance between the first and second fulcrums increases or decreases, thereby raising or lowering the platform. The height of the platform is related to the height of the reclined seat.
[0007] In the above structure, the first and second fulcrums are two opposing fulcrums in the first hinge, and the third and fourth fulcrums are two other opposing fulcrums in the first hinge. The first and second fulcrums move in a vertical direction, that is, perpendicular to the seat cushion or perpendicular to the ground; the third and fourth fulcrums move in a horizontal direction, that is, parallel to the seat cushion or parallel to the ground. A lifting device can be used to raise or lower the platform in the vertical direction, making the platform's vertical height the same as or approximately the same as the seat's vertical height after it is reclined. This eliminates the height difference between the reclined seat surface and the front and rear space planes of the seat, allowing the user to lie down comfortably and improving the user's comfort in this area.
[0008] In some embodiments, the aforementioned lifting device can be applied to a vehicle, meaning the device with seat folding function can be a vehicle. Taking the rear seats of a vehicle as an example, the lifting device can be located in front of the rear seats, that is, between the rear seats and the seats in front. This means that when the rear seats of the vehicle are folded down, the platform in the lifting device rises, so that the height of the plane after the seats are folded down is the same as or approximately the same as the height of the space in front of the seats. This allows users to rest in this area, thereby improving the user's driving experience.
[0009] One possible design is that the reverse motion is a moving-to-opposite motion. That is, when the third and fourth fulcrums move towards each other, the distance between the first and second fulcrums increases, causing the platform to rise. Alternatively, the reverse motion is a moving-away motion. That is, when the third and fourth fulcrums move away from each other, the distance between the first and second fulcrums decreases, causing the platform to descend.
[0010] In this design, the platform can be raised or lowered based on the different directions of movement of the third and fourth fulcrums. This physical structure is simple and highly reliable.
[0011] One possible design is that the distance the countertop can be raised or lowered ranges from 0 to 150 mm.
[0012] In this design, the distance range can be determined based on the overall size of the equipment space to prevent the table from being raised too much and damaging the components inside the equipment, as well as occupying the overall space of the equipment.
[0013] In one possible design, the lifting device also includes a second drive, a transmission element, and a baffle. One end of the transmission element is connected to the second drive, and the other end is connected to the baffle. The second drive controls the rotation of the transmission element to cause the baffle to flip along the first side of the platform.
[0014] In this design, a baffle is installed on the lifting device to provide privacy and safety. For example, taking the rear seats as an example, the lifting device is located in front of the rear seats. After the baffle flips away from the platform, it becomes perpendicular to the platform. This prevents users sitting in front of the lifting device from seeing what's behind the baffle through the rearview mirror, thus protecting the privacy of users resting in the rear seat space. Furthermore, in the event of a collision between items in the rear seat space and the baffle, the impact is on the front seats, not the seats in front of the baffle, thus protecting the safety of the front seats.
[0015] One possible design includes a second hinge, with one end of the second hinge located on the baffle and the other end located on the platform.
[0016] In this design, the hinge provides support for the baffle, thereby ensuring the reliability of the baffle's flipping and fixing.
[0017] One possible design is that the second drive is positioned on the surface of the table facing the base.
[0018] In this design, the second drive is placed on the countertop, eliminating the need to allocate space for the drive and thus saving space.
[0019] One possible design is that the angle between the baffle and the countertop ranges from 0 to 90 degrees.
[0020] In this design, controlling the included angle range is to prevent the baffle from over-rotating, avoid baffle damage, and ensure the reliability of the baffle.
[0021] One possible design is that the height of the baffle after it flips over ranges from 0 to 520 mm.
[0022] In this design, the height range can be determined based on the overall size of the equipment to prevent the excessive height of the baffle after it flips over from damaging the components inside the equipment and occupying too much of the overall space of the equipment.
[0023] Secondly, this application proposes a system including a controller and the lifting device described in the first aspect, wherein the controller is connected to a first drive in the lifting device. The controller is used to send a first rotation signal or a first stop signal to the first drive based on user operation, wherein the first rotation signal instructs the first drive to control the lead screw in the lifting device to rotate, and the first stop signal instructs the first drive to control the lead screw to stop rotating.
[0024] The controller can be a vehicle control unit (VCU), vehicle information unit (VIU), or vehicle domain controller (VDC) or other device that implements vehicle control; the controller can also be a smart driving domain control unit or mobile data center (MDC) or other device that implements smart driving or driver assistance functions, and its specific form is not limited.
[0025] One possible design is that the first rotation signal includes a first direction signal or a second direction signal. The first direction signal instructs the first driver to control the lead screw to rotate clockwise, and the second direction signal instructs the first driver to control the lead screw to rotate counterclockwise. When the lead screw rotates clockwise, it causes the third and fourth fulcrums of the first hinge in the lifting device to move towards each other, thereby increasing the distance between the first and second fulcrums of the first hinge and raising the platform in the lifting device. When the lead screw rotates counterclockwise, it causes the third and fourth fulcrums of the first hinge in the lifting device to move away from each other, thereby decreasing the distance between the first and second fulcrums of the first hinge and lowering the platform in the lifting device.
[0026] In one possible design, the controller is also connected to a second drive in the lifting device. The controller is also used to send a second rotation signal or a second stop signal to the second drive, the second rotation signal instructing the second drive to control the rotation of the transmission element in the lifting device, and the second stop signal instructing the second drive to control the rotation of the transmission element to stop.
[0027] In one possible design, the second rotation signal includes either a first flip signal or a second flip signal. The first flip signal instructs the second driver to control the transmission element to rotate clockwise, and the second flip signal instructs the second driver to control the transmission element to rotate counterclockwise. When the transmission element rotates clockwise, it causes the baffle in the lifting device to flip away from the platform; when the transmission element rotates counterclockwise, it causes the baffle in the lifting device to flip closer to the platform.
[0028] Thirdly, this application proposes a control method applied to the controller described in the second aspect above, the controller being connected to a first actuator in the lifting device. Based on this, the method includes: Receive control commands based on user operation, the control commands being used to instruct control of the lifting device.
[0029] Based on the first control command, a first rotation signal or a first stop signal is sent to the first driver. The first rotation signal instructs the first driver to control the lead screw in the lifting device to rotate, and the first stop signal instructs the first driver to control the lead screw to stop rotating.
[0030] In the above method, the control command can be triggered by the user according to the mode of the lifting device. For example, the modes of the lifting device include a rest mode and a privacy mode. The rest mode means that the height of the platform in the lifting device is the same as the height of the seat after it is reclined, thereby eliminating the height difference between the plane of the seat after it is reclined and the plane of the space in front of and behind the seat, thus improving the user's rest comfort. The privacy mode means that the height of the baffle in the lifting device after it is flipped is as close as possible to the top of the equipment, so as to separate the internal space of the equipment and ensure the privacy of the user behind the baffle. It should be noted that the above modes are only examples and are not limited in this application. In addition, the platform rise height corresponding to any mode can be preset according to parameters such as seat height and internal space size of the equipment, and is not limited in this application.
[0031] Optionally, the control commands can also be triggered by the user in real time. For example, if the user wants the platform to rise, they can trigger a control command to instruct the platform to rise.
[0032] One possible design is that the first rotation signal includes a first direction signal or a second direction signal. The first direction signal instructs the first driver to control the lead screw to rotate clockwise, and the second direction signal instructs the first driver to control the lead screw to rotate counterclockwise. When the lead screw rotates clockwise, it causes the third and fourth fulcrums of the first hinge in the lifting device to move towards each other, thereby increasing the distance between the first and second fulcrums of the first hinge and raising the platform in the lifting device. When the lead screw rotates counterclockwise, it causes the third and fourth fulcrums of the first hinge in the lifting device to move away from each other, thereby decreasing the distance between the first and second fulcrums of the first hinge and lowering the platform in the lifting device.
[0033] In one possible design, the controller is also connected to a second drive in the lifting device. The method further includes sending a second rotation signal or a second stop signal to the second drive, the second rotation signal instructing the second drive to control the rotation of a transmission element in the lifting device, and the second stop signal instructing the second drive to control the transmission element to stop rotating.
[0034] In this design, the controller can send a signal to the second driver either after the table rises or falls, or during the process of the table rises or falls; this application does not limit this.
[0035] In one possible design, the second rotation signal includes either a first flip signal or a second flip signal. The first flip signal instructs the second driver to control the transmission element to rotate clockwise, and the second flip signal instructs the second driver to control the transmission element to rotate counterclockwise. When the transmission element rotates clockwise, it causes the baffle in the lifting device to flip away from the platform; when the transmission element rotates counterclockwise, it causes the baffle in the lifting device to flip closer to the platform.
[0036] Fourthly, this application provides a terminal device that includes a seat with a reclining function and the lifting device described in the first aspect, or includes the system described in the second aspect.
[0037] In some embodiments, the terminal device is a vehicle, and the lifting device is located in front of the rear seats of the vehicle. Optionally, the vehicle includes a new energy vehicle, a hybrid vehicle, a range-extended electric vehicle, or a gasoline vehicle. This application can be applied to vehicles of different power types to reduce overall vehicle costs and ensure the user's driving experience.
[0038] The technical effects achievable in the third and fourth aspects described above can be described with reference to the technical effects achievable in any of the designs in the first and second aspects described above, and any repetitions will not be discussed. Based on the implementations provided in the above aspects, this application can also make further combinations to provide more implementations. Attached Figure Description

[0040] The seats in a vehicle provide physical support for occupants and ensure their safety and comfort while the vehicle is in motion. Please refer to [link / reference]. Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle provided in related technologies. Figure 1 In this context, the vehicle is a four-wheeled vehicle with three rows of seats. For ease of description, the row of seats closest to the trunk is referred to as the rear seats, and the middle row is referred to as the front seats. Optionally, vehicle seats generally include seat cushions and backrests.
[0041] To expand vehicle space and improve comfort, a seat-folding function has been proposed. Seat-folding can be understood as reclining the seat back forward or backward. For example, as described above... Figure 1 Taking the rear seats as an example, this application embodiment provides the following seat folding methods.
[0042] Method 1: Fold the seat back down.
[0043] Please see Figure 2 , Figure 2 This is a schematic diagram of a seat folding down structure provided in related technologies. Figure 2 In this embodiment, the backrest is folded down facing forward, or in other words, the backrest is folded down facing the seat cushion. At this time, the backrest and seat cushion are approximately parallel, thus freeing up the space that was before the backrest was folded down. In this embodiment, "forward" refers to the direction of vehicle travel.
[0044] Method 2: Fold down the seat back and flip the seat cushion.
[0045] Please see Figure 3 , Figure 3 This is a schematic diagram of another seat folding structure provided in related technologies. Figure 3 Figure a shows the seat in its upright position, where the backrest and seat cushion are approximately vertical, with an angle of nearly 90° between them, for comfortable seating. Figure 3 Figure b in the image shows the reclining position with the backrest facing forward. This position can be referenced above. Figure 2 The description of the embodiments in this application will not be repeated here. Figure 3 Figure c in the diagram shows the seat cushion flipped backward into the seat storage space, at which point both the space before the backrest was folded down and the space before the seat cushion was flipped are released. In this embodiment, "backward" refers to the direction in which the vehicle reverses.
[0046] like Figure 2 or Figure 3As shown, folding down the rear seats frees up space, expanding the vehicle's interior. Combined with the fore-and-aft space around the seats, this creates a reclining area. Taking the rear seats as an example, the space in front of the rear seats includes, but is not limited to, the space between the rear seats and the seats in front (essentially, the space in front of the rear seats to accommodate the passenger's legs), and the space behind the rear seats includes, but is not limited to, the trunk space. In essence, folding down the rear seats creates a combined space that can accommodate passengers lying down and resting, thus enhancing user comfort.
[0047] However, reference Figure 2 As can be seen, when the seats are folded down, the height of the folded-down surface is different from the height of the space behind the seats (the trunk surface is used as an example in the illustration). In other words, there is a horizontal height difference between the folded-down surface and the trunk surface. (Reference) Figure 3 It can be seen that when the seat is folded down, the height of the folded-down surface is different from the height of the space in front of the seat (i.e., the space in front of the seat that accommodates the passenger's feet). This difference in height results in an uneven surface in the large space created by the folded-down space combined with the space in front of and behind the seat. This uneven surface makes it difficult for users to rest in lying-down or side-lying positions, thus affecting the user's driving experience.
[0048] In view of this, the present application provides a lifting device and system, which aims to eliminate the height difference between the plane after the seat is folded down and the front and rear space plane of the seat, so that the height between the plane after the seat is folded down and the front and rear space plane of the seat is the same or approximately the same, thereby improving the user's comfort when using this part of the space.
[0049] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0050] In the following embodiments, the terminology used is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, “one or more” means one, two, or more; “and / or” describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.
[0051] In the description of this specification, references to "one embodiment" or "some embodiments," etc., mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification, do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.
[0052] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.
[0053] Please see Figure 4 , Figure 4 This is a schematic diagram of a lifting device provided in an embodiment of this application. The lifting device includes a first driver, a lead screw, a first hinge, a platform, and a base. The first hinge includes a first fulcrum, a second fulcrum, a third fulcrum, and a fourth fulcrum. The first fulcrum is connected to the platform, the second fulcrum is connected to the base, and the third and fourth fulcrums are engaged with the lead screw.
[0054] Optionally, the first driver is a motor, but this embodiment is not limited to this application.
[0055] It should be noted that the number of first hinges can be determined based on parameters such as their lifting capacity and the weight the platform needs to withstand; this embodiment of the application does not impose such limitations. The illustration uses four first hinges as an example, and each first hinge has the same structure and function. Therefore, the following description uses one first hinge as an example, without elaborating on the other first hinges. Similarly, the number of lead screws can be determined based on the number of first hinges, their own stiffness, and other parameters; this embodiment of the application does not impose such limitations.
[0056] In the above structure, the first hinge, also known as the lifting structure, consists of four fulcrums and four connecting rods. When the distance between two opposing fulcrums changes, the distance between the other two opposing fulcrums changes in a negative correlation. In other words, the distance between two opposing fulcrums is negatively correlated with the distance between the other two opposing fulcrums. Figure 4 Taking the first, second, third, and fourth fulcrums as an example, the first and second fulcrums are two opposite fulcrums in the first hinge, and the third and fourth fulcrums are two other opposite fulcrums in the first hinge. The distance between the third and fourth fulcrums is negatively correlated with the distance between the first and second fulcrums. For example, when the distance between the third and fourth fulcrums increases or decreases, the distance between the first and second fulcrums decreases or increases accordingly.
[0057] In this embodiment, the first driver is used to control the rotation of the lead screw. Since the lead screw is meshed with the third and fourth fulcrums of the first hinge, the rotation of the lead screw can drive the third and fourth fulcrums to move in opposite directions.
[0058] Optionally, the transmission method for the lead screw to drive the movement of the third and fourth fulcrums is threaded transmission. For example, nuts (or sliders) are set at the positions of both the third and fourth fulcrums, and the lead screw passes through these nuts, or in other words, the lead screw and the nuts are engaged. Since the nut's rotation is restricted by two related connecting rods (such as the nut corresponding to the third fulcrum being restricted by the connecting rod between the first and third fulcrums, and the connecting rod between the second and third fulcrums), the nut can only perform linear motion on the lead screw. That is, when the lead screw rotates, based on threaded transmission, the rotational motion is converted into the linear motion of the nut. This means that the third and fourth fulcrums perform linear motion on the lead screw. It should be noted that the threads in the nuts corresponding to the third and fourth fulcrums are opposite, therefore the third and fourth fulcrums perform opposite linear motions on the lead screw (hereinafter referred to as reverse motion).
[0059] Based on the above, when the third and fourth fulcrums move in opposite directions, the distance between them decreases or increases, which in turn causes the distance between the first and second fulcrums to increase or decrease. Specifically, the first and second fulcrums move in a vertical direction, either perpendicular to the seat cushion or perpendicular to the ground; the third and fourth fulcrums move in a horizontal direction, either parallel to the seat cushion or parallel to the ground.
[0060] In this embodiment, the first fulcrum is fixedly connected to the tabletop, and the second fulcrum is fixedly connected to the base. The base is typically mounted on a device with a reclining seat function, meaning the base is stationary, and consequently, the second fulcrum is also stationary. Therefore, any increase or decrease in the distance between the first and second fulcrums is reflected in the first fulcrum; in other words, it is reflected in the first fulcrum rising or falling vertically. Thus, the first fulcrum can raise or lower the tabletop. The raising of the tabletop by the first fulcrum can be simply referred to as lifting.
[0061] In this embodiment, the lifting device is applied to a device with a seat reclining function. The base of the lifting device is located in the device near the seat, i.e., the lifting device is located in the device near the seat. Because the height of the platform and the height of the reclined seat (e.g., ...) Figure 3 The height of the platform after the seat is folded down is related to the height of the flat surface. Therefore, a lifting device can be used to raise or lower the vertical height of the platform so that it is the same as or approximately the same as the vertical height of the seat after folding down. This eliminates the height difference between the flat surface of the folded-down seat and the front and rear space planes of the seat, making the height of the flat surface of the folded-down seat the same as or approximately the same as the height of the front and rear space planes of the seat. In this way, the large space plane formed by the space released after the seat is folded down and the front and rear space of the seat is relatively flat, without any unevenness. This allows users to rest in this large space in a lying or side-lying position, improving the user's comfort when using this part of the space.
[0062] Optionally, the size, material, and other attributes of the platform, as well as the size, material, and other attributes of the base, are determined based on the internal space of the equipment where the lifting device is located, and this embodiment of the application does not impose such limitations. For example, the base has a square structure and is used to physically support and protect the first hinge.
[0063] Optionally, the device is a vehicle. Taking the rear seats of a vehicle as an example, the lifting device can be located in front of the rear seats, that is, between the rear seats and the seats in front of them. This means that when the rear seats of the vehicle are folded down, the platform in the lifting device rises, so that the height of the flat surface after the seats are folded down is the same as or approximately the same as the height of the space in front of the seats. This allows users to rest in this area, thereby improving the user's driving experience.
[0064] In this embodiment of the application, the movement directions of the third and fourth fulcrums of the first hinge may include the following scenarios.
[0065] Scenario 1: The third and fourth fulcrums move toward each other.
[0066] In Scenario 1, the movement of the third and fourth fulcrums toward each other can be understood as the third and fourth fulcrums moving closer to each other. At this time, the distance between the third and fourth fulcrums decreases, which in turn increases the distance between the first and second fulcrums, thereby enabling the first fulcrum to raise the platform.
[0067] Scenario 2: The third and fourth fulcrums move in opposite directions.
[0068] In scenario 2, the opposite movement of the third and fourth fulcrums can be understood as the mutual principle between the third and fourth fulcrums. At this time, the distance between the third and fourth fulcrums increases, which in turn leads to the decrease in the distance between the first and second fulcrums, thereby enabling the first fulcrum to drive the platform to descend.
[0069] Optionally, the range of distance the platform can be raised or lowered is 0-150mm. Alternatively, the range of movement between the first and second support points (or between the third and fourth support points) is 0-150mm. It should be noted that this range can be determined based on the internal space of the equipment (such as a vehicle) where the lifting device is located, and this embodiment does not impose such a limitation. It is understood that a reasonable range can prevent excessive platform raising from damaging components within the equipment and from occupying too much internal space. In some embodiments, the range of distance the platform can be raised or lowered can be greater than 150mm, such as 200mm.
[0070] To better illustrate the above technical solution, the following will combine... Figure 3 The example shown is in diagram C. Please refer to [link / reference]. Figure 5 , Figure 5This is a schematic diagram of the structure of a lifting device after raising the platform, as provided in an embodiment of this application. It can be seen that the platform height of the lifting device is the same as or approximately the same as the height of the plane after the seat is folded down, eliminating the horizontal height difference between the plane after the seat is folded down and the plane in front of the seat. Thus, the large space created by combining the space released after the seat is folded down with the space in front of and behind the seat is more conducive to user rest and use, thereby improving user comfort and overall driving experience.
[0071] Based on the above Figure 4 , Figure 6 This is a schematic diagram of another lifting device provided in an embodiment of this application. The lifting device includes, in addition to... Figure 4 In addition to the devices mentioned above, it also includes a second driver, a transmission element, and a baffle. One end of the transmission element is connected to the second driver, and the other end of the transmission element is connected to the baffle.
[0072] Optionally, the second driver is a motor, and the driving element is a gear; however, this embodiment is not limited to this.
[0073] In this embodiment, the second driver controls the rotation of the power transmission element, which in turn drives the baffle to flip along the first side of the platform. The first side refers to the side furthest from the reclined seat. Figure 5 For example, the side of the table closest to the seat is called the second side, and the side of the table opposite the second side is called the first side.
[0074] Optionally, the baffle can flip in either a forward or backward direction. In other words, the baffle can flip in either a direction closer to the tabletop or a direction further away from the tabletop. Taking the direction further away from the tabletop as an example... Figure 7 This is a schematic diagram of the structure of a baffle before it flips, as provided in an embodiment of this application. Figure 7 As shown, the baffle is attached to the table surface. Figure 8 This is a schematic diagram of the structure of a baffle after it has been flipped, as provided in an embodiment of this application. Figure 8 As shown, the baffle is flipped (or unfolded) based on the second actuator, so that the baffle stands upright on the table.
[0075] It's understandable that this barrier can provide privacy and security. Below, we'll combine... Figure 3 The example shown is in diagram C. Please refer to [link / reference]. Figure 9 , Figure 9This is a schematic diagram of the structure of a lifting device after raising the platform and unfolding the baffle, provided in an embodiment of this application. It can be seen that the platform height of the lifting device is the same as or approximately the same as the height of the plane after the seats are folded down, eliminating the height difference between the plane after the seats are folded down and the plane in front of the seats in the horizontal direction, thereby improving the user's driving experience. Because of the baffle, the user sitting in front of the lifting device (i.e., the user sitting in the front seat) cannot see the scene behind the baffle through the rearview mirror, thus protecting the privacy of users resting in the rear seat space. In addition, when items in the rear seat space (such as a trunk) collide, it is the baffle that is impacted, not the seats in front of the baffle, thus protecting the safety of the front seats.
[0076] Optionally, the lifting device may also include a second hinge. (See reference) Figure 6 One end of the second hinge is disposed on the baffle, and the other end is disposed on the tabletop. The second hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Specifically, the second hinge connects the tabletop and the baffle, allowing the baffle to rotate relative to the tabletop, thereby providing physical support for the baffle and ensuring the reliability of its rotation. It should be noted that the embodiment of this application does not limit the form of the second hinge.
[0077] Optionally, the connection method between one end of the second hinge and the baffle includes one or more of the following: welding, bolting, riveting, and bonding. This embodiment of the application does not limit this method. Similarly, the connection method between one end of the second hinge and the tabletop includes one or more of the following: welding, bolting, riveting, and bonding. For example, one end of the second hinge can be fixed to the baffle and the other end to the tabletop using a bolt connection. The bolt type can be M6-M10, and this embodiment of the application does not limit this method.
[0078] Optionally, the second actuator is disposed on the surface of the table facing the base. This eliminates the need to allocate space for the actuator, thereby saving space. The connection method between the second actuator and the table includes one or more of the following: welding, bolting, riveting, and bonding, which are not limited to the embodiments described herein.
[0079] Optionally, the angle between the baffle and the platform can range from 0 to 90°. It should be noted that this angle range can be determined based on parameters such as the internal space size of the equipment containing the lifting device and the arrangement of other internal components; this embodiment does not impose such limitations. The angle range is used to prevent excessive tilting of the baffle, avoid damage to the baffle, and ensure the reliability of the baffle.
[0080] Optionally, the height range after the baffle flips is 0-520mm. It should be noted that this height range can be determined based on the internal space of the equipment containing the lifting device, and this embodiment does not impose such a limitation. The height range is designed to prevent excessive height after the baffle flips from damaging components within the equipment and from occupying too much overall space.
[0081] In summary, assuming the aforementioned lifting device is applied to a vehicle, when the rear seats are folded down, it can eliminate the horizontal height difference between the folded-down surface and the space in front of the seats, ensuring a better user experience. Furthermore, the partition protects the privacy of users resting in the rear seat space, prevents collisions with the front seats, and safeguards the safety of the front seats.
[0082] Optionally, for a single vehicle, one or more of the above-mentioned lifting devices may be used. The number of lifting devices may be determined according to the requirements and the physical structure of the seat, and this application embodiment does not limit this.
[0083] Based on the above description, this application also provides a system, please refer to... Figure 10 , Figure 10 This is a schematic diagram of a system architecture provided for an embodiment of this application. For example... Figure 10 As shown, the system includes a controller, and the aforementioned Figures 4-9 The lifting device described herein includes a controller connected to it; in other words, the controller is connected to a first drive and / or a second drive within the lifting device. The drive is used to send signals to the first drive and / or the second drive to control them, as described below.
[0084] Optionally, the controller can be a vehicle control unit (VCU), vehicle information unit (VIU), or vehicle domain controller (VDC) or other device that implements vehicle control; the controller can also be an intelligent driving domain control unit or a mobile data center (MDC) or other device used to implement intelligent driving or assisted driving functions, and its specific form is not limited in the embodiments of this application.
[0085] In some embodiments, the controller is configured to send a first rotation signal or a first stop signal to the first driver based on user operation. The first rotation signal instructs the first driver to control the lead screw in the lifting device to rotate, and the first stop signal instructs the first driver to control the lead screw to stop rotating.
[0086] In some embodiments, the first rotation signal includes a first direction signal or a second direction signal, wherein the first direction signal instructs the first driver to control the lead screw to rotate clockwise, and the second direction signal instructs the first driver to control the lead screw to rotate counterclockwise. Alternatively, the first direction signal instructs the first driver to control the lead screw to rotate counterclockwise, and the second direction signal instructs the first driver to control the lead screw to rotate clockwise.
[0087] Optionally, when the lead screw rotates clockwise, it causes the third and fourth fulcrums of the first hinge in the lifting device to move towards each other, increasing the distance between the first and second fulcrums of the first hinge and raising the platform in the lifting device. When the lead screw rotates counterclockwise, it causes the third and fourth fulcrums of the first hinge in the lifting device to move away from each other, decreasing the distance between the first and second fulcrums of the first hinge and lowering the platform in the lifting device. Alternatively, when the lead screw rotates clockwise, it causes the third and fourth fulcrums of the first hinge in the lifting device to move towards each other, decreasing the distance between the first and second fulcrums of the first hinge and lowering the platform in the lifting device. When the lead screw rotates counterclockwise, it causes the third and fourth fulcrums of the first hinge in the lifting device to move away from each other, increasing the distance between the first and second fulcrums of the first hinge and raising the platform in the lifting device. The principle of the transmission between the third and fourth fulcrums driven by the lead screw can be referred to the above content, and will not be repeated here in the embodiments of this application.
[0088] In some embodiments, the controller is also connected to a second drive in the lifting device. The controller is also configured to send a second rotation signal or a second stop signal to the second drive, the second rotation signal instructing the second drive to control the transmission element in the lifting device to rotate, and the second stop signal instructing the second drive to control the transmission element to stop rotating.
[0089] In some embodiments, the second rotation signal includes a first flip signal or a second flip signal, wherein the first flip signal instructs the second driver to control the transmission element to rotate clockwise, and the second flip signal instructs the second driver to control the transmission element to rotate counterclockwise. Alternatively, the first flip signal instructs the second driver to control the transmission element to rotate counterclockwise, and the second flip signal instructs the second driver to control the transmission element to rotate clockwise.
[0090] Optionally, when the transmission element rotates clockwise, it causes the baffle in the lifting device to flip away from the platform; when the transmission element rotates counterclockwise, it causes the baffle in the lifting device to flip towards the platform. Alternatively, when the transmission element rotates clockwise, it causes the baffle in the lifting device to flip towards the platform; when the transmission element rotates counterclockwise, it causes the baffle in the lifting device to flip away from the platform. The principle of the transmission element causing the baffle to flip can be referred to the above content, and will not be repeated here in the embodiments of this application.
[0091] Based on the above description, the controller can execute the following control methods: Step 10: Receive control commands based on user operation, which are used to instruct the lifting device to be controlled.
[0092] Step 20: Based on the first control command, send a first rotation signal or a first stop signal to the first driver. The first rotation signal instructs the first driver to control the lead screw in the lifting device to rotate, and the first stop signal instructs the first driver to control the lead screw to stop rotating.
[0093] In the above method, the control command can be triggered by the user according to the mode of the lifting device. For example, the modes of the lifting device include a rest mode and a privacy mode. The rest mode means that the height of the platform in the lifting device is the same as the height of the seat after it is reclined, thereby eliminating the height difference between the plane of the seat after it is reclined and the front and rear space plane of the seat, thus improving the user's rest comfort. The privacy mode means that the height of the baffle after it is flipped in the lifting device is as close as possible to the top of the equipment (such as the roof of a vehicle) to achieve the purpose of separating the internal space of the equipment and ensuring the privacy of the user behind the baffle. It should be noted that the above modes are only examples and are not limited in this application. In addition, the platform rising height corresponding to any mode can be preset according to parameters such as seat height and internal space size of the equipment, and the embodiments of this application are not limited in this application.
[0094] Optionally, the control commands can also be triggered by the user in real time. For example, if the user wants the platform to rise, they can trigger a control command to instruct the platform to rise.
[0095] In some embodiments, the method further includes sending a second rotation signal or a second stop signal to a second driver, wherein the second rotation signal instructs the second driver to control the transmission element in the lifting device to rotate, and the second stop signal instructs the second driver to control the transmission element to stop rotating.
[0096] Optionally, the controller may send a signal to the second driver after the table rises or falls, or during the process of the table rises or falls. This application embodiment does not limit this.
[0097] In this method, the descriptions of the first rotation signal and the second rotation signal can be found above, and will not be repeated here in the embodiments of this application.
