Abstract
Description
Technical Field
[0001] This application relates to the field of seating technology, and more specifically, to a seating and terminal device. Background Technology
[0002] With social development and the improvement of people's living standards, drivers and passengers have increasingly higher requirements for the functionality of seats in their devices. For example, maintaining a sitting posture for extended periods can lead to fatigue in areas such as the lower back and neck, and even cause health risks. Drivers and passengers expect seats to provide better comfort and health benefits. In addition, drivers and passengers also have higher requirements for the safety performance of seats, such as providing more effective protection in emergency situations.
[0003] However, existing seats are insufficient to meet the diverse needs of drivers and passengers, resulting in a poor driving and riding experience. Summary of the Invention
[0004] This application provides a seat and terminal device that integrates a seat belt and a massage device, which can meet the diverse needs of drivers and passengers and improve their driving and riding experience.
[0005] In a first aspect, a seat is provided, wherein a drive device, a massage device, and a retracting device are provided on the backrest frame of the seat. The drive device is used to drive the massage device to slide relative to the backrest frame, and the drive device and the massage device are used to realize the massage function. The retracting device is used to retract the seat belt. The drive device, massage device, and retracting device are all located on the same side of the backrest frame, and along the sliding direction of the massage device, the drive device and the retracting device are located at both ends of the massage device.
[0006] The seat back frame integrates a drive mechanism and a massage system, which provide massage functionality to alleviate fatigue during long journeys and offer enhanced comfort and health for passengers. Furthermore, the seat back frame also integrates a retractable mechanism for the seatbelt, meaning the seatbelt is integrated into the backrest. Regardless of seat adjustment, the seatbelt remains in the optimal protective position for the occupants, effectively protecting them in emergencies and enhancing safety. Moreover, the placement of the drive mechanism, massage system, and retractable mechanism ensures they do not interfere with each other, maximizing both the massage range and the seatbelt's protective performance.
[0007] In summary, the seat integrates not only massage functions but also a seatbelt retraction mechanism. This allows the seat to not only provide massage but also protect occupants in dangerous situations, thus meeting diverse needs and enhancing the overall driving and riding experience.
[0008] In conjunction with the first aspect, in some implementations of the first aspect, the driving device is located below the massage device, and the winding device is located above the massage device.
[0009] For example, the drive unit can be positioned directly below the massage device, and the winding device can be positioned at the upper right or upper left of the massage device. For instance, if the terminal device is a vehicle and the seat is the left-hand seat, the winding device is positioned at the upper left of the massage device. Or, if the terminal device is a vehicle and the seat is the right-hand seat, the winding device is positioned at the upper right of the massage device. Or, if the terminal device is a vehicle and the seat is the middle seat, the winding device is positioned at the upper right or upper left of the massage device.
[0010] It should be noted that the directions mentioned above are based on the direction from which the occupants are seated in the vehicle.
[0011] The retractor is positioned higher than the drive unit. This allows the seatbelt to utilize its "high-mounted, low-use" mechanical advantage to firmly lock the most vulnerable upper body of the occupant, while simultaneously using gravity to ensure smoothness and reliability during daily use.
[0012] The drive unit is positioned lower than the winding unit. This lowers the center of gravity of the seat pair and improves seat stability.
[0013] In conjunction with the first aspect, in some implementations of the first aspect, two guide rails are provided on the backrest frame, the extension direction of the two guide rails is parallel to the sliding direction of the massage device, the two guide rails are provided on both sides of the massage device, and the massage device is slidably connected to the backrest frame through the two guide rails.
[0014] In one implementation, the driving device includes two driving components arranged in parallel along the orientation of two guide rails. These two driving components drive the massage device to slide along the two guide rails. In other words, the driving device uses a one-to-one method to drive the massage device to slide along the two guide rails. This collaborative operation of the two driving components ensures that the massage device slides synchronously on the two guide rails, preventing deviation or imbalance and resulting in a smoother massage process. Consequently, the massage performance of the seat is improved, further enhancing the driving and riding experience for passengers.
[0015] In one implementation, the driving device includes a driving component for driving the massage device to slide along two guide rails. That is, the driving device uses a one-to-two configuration to drive the massage device to slide along the two guide rails. This reduces the size and complexity of the driving device, saves space in the backrest frame, and facilitates the deployment of other components within the backrest frame.
[0016] In conjunction with the first aspect, in some implementations of the first aspect, the drive unit further includes a housing fixed to the backrest frame, and two drive components are disposed within the housing. That is, the two drive components share a single housing, thereby reducing the complexity of seat assembly and the cost of seat maintenance.
[0017] In conjunction with the first aspect, in some implementations of the first aspect, the massage device includes a massage mechanism and a kneading device, the massage mechanism being used to control the kneading device to perform kneading, the kneading device being connected to the side of the massage mechanism and along the sliding direction of the massage device, and a drive device and a winding device being disposed at both ends of the kneading device.
[0018] The positioning of the drive unit, kneading unit, and retracting unit ensures that they do not interfere with each other. This design guarantees the massage stroke of the massage unit, the kneading performance of the kneading unit, and the safety protection of the seat belt for the occupants. As a result, the seat can meet the diverse needs of the occupants, thereby helping to further improve their driving and riding experience.
[0019] In conjunction with the first aspect, in some implementations of the first aspect, the kneading device includes a dual-arm structure extending from the side of the massage mechanism towards the front of the massage mechanism, and the dual-arm structure is extendable along the front-back frame. When the dual-arm structure is in a non-operating state, the height of the extended end of the lower mechanical arm in the dual-arm structure is less than the height of the extended end of the upper mechanical arm in the dual-arm structure.
[0020] When passengers adjust the seat back to a fully reclined position (including a zero-gravity position), the extension of the lower robotic arm exerts less pressure on the passenger's back, thus reducing the feeling of foreign objects and improving passenger comfort.
[0021] In conjunction with the first aspect, in some implementations of the first aspect, the lower robotic arm and the upper robotic arm are of equal length. Along the arrangement direction of the lower and upper robotic arms, the angles between the extension direction of the lower robotic arm and the extension direction of the upper robotic arm and the massage mechanism are respectively a first angle and a second angle. The first angle is smaller than the second angle.
[0022] While ensuring that the lengths of the two robotic arms are equal, the height of the extension end of the robotic arm can be changed by altering the angle between the robotic arm and the massage mechanism. This allows for a design where, when the dual robotic arm structure is not in operation, the height of the extension end of the lower robotic arm is less than the height of the extension end of the upper robotic arm, thereby reducing the complexity of the dual robotic arm structure.
[0023] In conjunction with the first aspect, in some implementations of the first aspect, the difference between the second angle and the first angle is less than or equal to 2 degrees.
[0024] Setting the first angle to be within 2 degrees smaller than the second angle not only ensures the kneading performance of the kneading device, but also reduces the feeling of foreign objects for drivers and passengers in a reclining position (including zero-gravity posture), which is conducive to further improving the driving and riding experience of drivers and passengers.
[0025] In conjunction with the first aspect, in some implementations of the first aspect, the seat includes a backrest cover for wrapping the backrest frame, and the distance between the extended end of the lower robotic arm and the backrest cover is greater than or equal to a first distance. This reduces the feeling of foreign objects in the driver's or passenger's body in a fully reclining position (including a zero-gravity posture), thus further improving the driving and riding experience.
[0026] For example, the first distance is about 25 millimeters.
[0027] In conjunction with the first aspect, in some implementations of the first aspect, the height of the extended end of the lower robotic arm is greater than the first height. This ensures the kneading performance of the kneading device, which is beneficial for further improving the driving and riding experience for passengers.
[0028] For example, the first height is about 50 millimeters.
[0029] In conjunction with the first aspect, in some implementations of the first aspect, the seat includes a mounting base fixed to a backrest frame, a drive unit and a massage unit disposed on the side of the mounting base opposite to the backrest frame, and the drive unit and the massage unit are slidably connected to the mounting base respectively. A retractable device is fixed to the side of the mounting base opposite to the backrest frame.
[0030] In other words, the drive unit, massage unit, and retraction unit share a single mounting base. This single mounting base allows the drive unit and massage unit to slide relative to the backrest frame, while also securing the retraction unit, resulting in a simpler seat structure. Furthermore, mounting the drive unit, massage unit, and retraction unit on the same side of the mounting base reduces the complexity of seat assembly and maintenance costs.
[0031] In conjunction with the first aspect, in some implementations of the first aspect, the seat includes a first mounting seat and a second mounting seat, which are disposed on the same side of the backrest frame and are arranged along the sliding direction of the massage device. The side of the first mounting seat opposite to the backrest frame is used to fix a drive device and the massage device, and the massage device drives the first mounting seat and the drive device to slide relative to the backrest frame. The second mounting seat is fixed to the backrest frame, and the side of the second mounting seat opposite to the backrest frame is used to fix a retracting device.
[0032] In other words, the drive unit and massage unit each have their own separate mounting base, as does the retraction unit. This avoids interference between the massage function-related devices and the retraction seat belt device during installation and operation, thereby improving the reliability of the seat's massage function and protective performance.
[0033] In a second aspect, a terminal device is provided, comprising: a seat as described in the first aspect and any implementation thereof.
[0034] In conjunction with the second aspect, in some implementations of the second aspect, the terminal device is a vehicle.
[0035] In one implementation, the vehicle has two rows of seats, which are rear seats.
[0036] In one implementation, the vehicle has three rows of seats, which are either middle or rear rows. Attached Figure Description

[0047] The technical solutions in this application will now be described with reference to the accompanying drawings.
[0048] In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B. "At least one" refers to one or more. For example, "at least one of A or B" describes the association relationship of related objects, indicating that three relationships can exist. For example, at least one of A and B can represent: A existing alone, A and B existing simultaneously, and B existing alone.
[0049] In this application, prefixes such as "first" and "second" are used only to distinguish different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects.
[0050] In the description of this application, it should be understood that the terms "inner", "outer", "bottom", "top", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.
[0051] The term "equal to" in this application is not strictly equal in the strict sense, but rather within the allowable error range. Similarly, "parallel" is not strictly parallel in the strict sense, but rather within the allowable error range. Likewise, "perpendicular" is not strictly perpendicular in the strict sense, but rather within the allowable error range.
[0052] In this embodiment, the same reference numeral denotes the same component or part. In this embodiment, for multiple identical parts, the reference numeral may only be used to label one of the parts as an example. The reference numerals also apply to other identical parts or components. Furthermore, the dimensions and sizes of the parts shown in the drawings are merely exemplary.
[0053] This application provides a terminal device. Exemplarily, the terminal device may include a driving device. This driving device may include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, the driving device may be a vehicle, which is a vehicle in a broad sense, including transportation vehicles (such as commercial vehicles, passenger cars, trucks, flying cars, trains, high-speed trains, bullet trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, large harvesters, etc.), amusement equipment, toy vehicles, etc. This application does not specifically limit the type of vehicle.
[0054] The terminal device may include one or more seats for drivers and passengers to sit on. The number of seats on different types of terminal devices may be the same or different; this application embodiment does not limit this. For example, the type of terminal device may include the category of terminal device, the model of terminal device, etc.
[0055] The following is combined Figure 1 and Figure 2 This application provides a detailed description of the terminal device provided in its embodiments. For example, the terminal device can be such as... Figure 1 The terminal equipment for vehicle 1 shown can also be as follows: Figure 2 Vehicle 2 is shown.
[0056] Figure 1 and Figure 2 These are schematic diagrams of vehicles applicable to embodiments of this application. Figure 1 As shown, vehicle 1 has two rows of four / five seats. The front row can be equipped with two individual seats 10, and the rear row can use a long bench seat 20. (As shown...) Figure 2 As shown, vehicle 2 has three rows of six / seven seats. The front and middle rows can each have two individual seats 10, and the rear rows can use a long bench seat 20. Compared to the individual seats 10, the long bench seat 20 provides multiple seating positions, accommodating multiple passengers. For example, the long bench seat 20 can include two or three seats, accommodating two or three people.
[0057] Existing seats are insufficient to meet the diverse needs of drivers and passengers, resulting in a poor driving and riding experience.
[0058] Therefore, this application also provides a seat 100. This seat 100 can be applied to a terminal device, and can be any seat within the terminal device. For example, the terminal device is... Figure 1 The vehicle 1 shown has 100 seats as follows: Figure 1 The example shown is either a freestanding seat 10 or a bench seat 20. For example, the terminal device is... Figure 2The vehicle 2 shown has 100 seats as described above. Figure 2 The seat 10 or seat 20 shown is an example. For example, if the terminal equipment is an airplane, seat 100 is a seat in the first-class cabin of the airplane. For example, if the terminal equipment is a high-speed train, seat 100 is a seat in the first-class cabin of the high-speed train.
[0059] It should be noted that when seat 100 is a long bench seat 20, the structure of seat 100 can refer to the structure of the entire long bench seat 20, or it can refer to the structure of a single seat in the long bench seat 20.
[0060] The following is combined Figures 3 to 11 The seat 100 provided in the embodiments of this application will be described in detail.
[0061] For illustrative purposes, Figures 3 to 11 The x-direction can be understood as the left-right direction of the seat 100, the left-right direction of the backrest 110, the left-right direction of the cushion 120, and the arrangement direction of the two guide rails R. The y-direction can be understood as the front-back direction of the seat 100, the front-back direction of the backrest 110, and the front-back direction of the cushion 120. The z-direction can be understood as the up-down direction of the seat 100, the up-down direction of the backrest 110, the up-down direction of the cushion 120, the setting direction of the drive device 140, the massage device 150 and the retracting device 160, the sliding direction of the massage device 150, and the extension direction of the two guide rails R.
[0062] Figure 3 This is a schematic diagram of a seat 100 provided in an embodiment of this application. Figure 3 As shown, the seat 100 includes a backrest 110, a seat cushion 120, and a headrest 130. The seat cushion 120 is mainly used to support the hips and legs of the driver and passenger, the backrest 110 is used to support the back, shoulders, and waist of the driver and passenger, and the headrest 130 is mainly used to support the head and neck of the driver and passenger.
[0063] Figure 4 for Figure 3 An exploded view of seat 100 is shown. For example, as... Figure 4 As shown, the seat 100 includes a cover 100-1 and a frame 100-2. The frame 100-2 is mainly used for support and serves as the mounting base for the internal components of the seat 100. The cover 100-1 is used to wrap around the frame 100-2 to protect it and provide comfort for the occupants. Figure 4As shown, the cover 100-1 includes a backrest cover 111, a seat cushion cover 121, and a headrest cover 131. The frame 100-2 includes a backrest frame 112, a seat cushion frame 122, and a headrest frame 132. The backrest cover 111 is used to cover the backrest frame 112 to form a backrest 110. The seat cushion cover 121 is used to cover the seat cushion frame 122 to form a seat cushion 120. The headrest cover 131 is used to cover the headrest frame 132 to form a headrest 130.
[0064] In some embodiments, a filler (or foam layer) may be provided between the faceplate 100-1 and the frame 100-2. The filler can provide support, cushioning, and shape the seat 100.
[0065] like Figure 4 As shown, the backrest frame 112 of the seat 100 is equipped with a drive device 140 and a massage device 150. The massage device 150 is slidably connected to the backrest frame 112. The drive device 140 is used to drive the massage device 150 to slide relative to the backrest frame 112. The drive device 140 and the massage device 150 are used to realize the massage function. For example, the massage device 150 is slidably connected to the backrest frame 112 along the z-direction or the opposite direction of the z-direction, and the drive device 140 can drive the massage device 150 to slide relative to the backrest frame 112 along the z-direction or the opposite direction of the z-direction.
[0066] For example, the massage device 150 is slidably connected to the backrest frame 112 via a guide rail R.
[0067] In one embodiment, a guide rail R is provided on the backrest frame 112, and the extension direction of the guide rail R is parallel to the sliding direction of the massage device 150. In addition, the driving device 140 includes a driving member 141, which is used to drive the massage device 150 to slide along the guide rail R, so as to realize the sliding of the massage device 150 relative to the backrest frame 112.
[0068] Figure 5 This is a schematic diagram of a backrest frame 112 provided in an embodiment of this application. For example, as... Figure 5 As shown, a guide rail R on the backrest frame 112 extends parallel to the z-direction. A drive element 141 of the drive device 140 drives the massage device 150 to slide along the guide rail R.
[0069] In one embodiment, the backrest frame 112 is provided with two guide rails R, which are fixed to the backrest frame 112. The extending direction of the two guide rails R is parallel to the sliding direction of the massage device 150, and the two guide rails R are disposed on both sides of the massage device 150. Furthermore, the driving device 140 includes a driving member 141, which drives the massage device 150 to slide along the two guide rails R, thereby enabling the massage device 150 to slide relative to the backrest frame 112. In other words, the driving device 140 uses a one-to-two method to drive the massage device 150 to slide along the two guide rails R. This reduces the size and complexity of the driving device 140, saves space in the backrest frame 112, and facilitates the deployment of other components in the backrest frame 112.
[0070] Figure 6 This is a schematic diagram of another backrest frame 112 provided in an embodiment of this application. For example, as... Figure 6 As shown, the two guide rails R on the backrest frame 112 extend parallel to the z-direction, and are positioned parallel to the x-direction. Furthermore, the two guide rails R are positioned on both sides of the massage device 150 along the x-direction. A drive member 141 of the drive device 140 drives the massage device 150 to slide along the two guide rails R.
[0071] In one embodiment, the backrest frame 112 is provided with two guide rails R. The driving device 140 includes two driving members 141, which are arranged in parallel along the arrangement direction of the two guide rails R. The two driving members 141 are used to drive the massage device 150 to slide along the two guide rails R. That is, the driving device 140 drives the massage device 150 to slide along the two guide rails in a one-to-one manner. In this way, the two driving members 141 work together to ensure that the massage device 150 slides synchronously on the two guide rails R, avoiding the massage device 150 from deviating or becoming unbalanced, making the massage process more stable. Therefore, the massage performance of the seat 100 can be improved, further enhancing the driving and riding experience of the occupants.
[0072] In one embodiment, the drive device 140 further includes a housing 142, which is fixed to the backrest frame 112 and is used to house the drive element 141 of the drive device 140. For example, as Figure 6 As shown, a drive element 141 of the drive device 140 is disposed within the housing 142. For example, as... Figure 7 As shown, both drive components 141 of the drive unit 140 are housed within the housing 142. That is, the two drive components 141 of the drive unit 140 share a single housing, thereby reducing the complexity of assembling the seat 100 and the cost of maintaining the seat 100.
[0073] Figure 7This is a schematic diagram of another backrest frame 112 provided in an embodiment of this application. For example, as... Figure 6 As shown, the two guide rails R on the backrest frame 112 extend parallel to the z-direction, and are positioned parallel to the x-direction. Along the x-direction, the two guide rails R are positioned on both sides of the massage device 150. Furthermore, the two drive members 141 of the drive device 140 are arranged in parallel along the x-direction, and are used to drive the massage device 150 to slide along the two guide rails R.
[0074] The setting positions of the two guide rails R can be referred to the relevant description above, and will not be repeated in this embodiment.
[0075] For example, in the embodiments described above, the guide rail R can be a slide groove, and the massage device 150 has a slider that can slide along the guide rail R to achieve a sliding connection between the massage device 150 and the backrest frame 112. Alternatively, the guide rail R can also be a slider, and the massage device 150 has a slide groove that can slide along the guide rail R to achieve a sliding connection between the massage device 150 and the backrest frame 112. For example, as... Figure 5 and Figure 7 As shown, the two guide rails R are sliders, and the massage device 150 has two sliding grooves G. The two sliding grooves G of the massage device 150 slide along the two guide rails R to realize the sliding connection between the massage device 150 and the backrest frame 112.
[0076] like Figures 4 to 7 As shown, the backrest frame 112 of the seat 100 is equipped with a retractable device 160 for retracting the seat belt 161. The backrest frame 112 of the seat 100 integrates a drive unit 140 and a massage device 150, which provide a massage function to alleviate fatigue experienced by occupants during long periods of sitting in the seat 100, offering better comfort and health. Furthermore, the retractable device 160 also retracts the seat belt 161, meaning the seat belt 161 is integrated into the backrest 110. Regardless of how the seat 100 is adjusted, the seat belt 161 remains in the most ideal protective position for the occupants. In emergencies, the seat belt 161 effectively protects the occupants, improving their safety performance.
[0077] The drive unit 140, massage unit 150, and winding unit 160 are all located on the same side of the backrest frame 112 (e.g., Figures 4 to 7As shown in the front side), and along the sliding direction of the massage device 150, that is, along the z-direction, the drive device 140 and the winding device 160 are disposed at both ends of the massage device 150. In this way, the positional design of the drive device 140, the massage device 150 and the winding device 160 will not interfere with each other, which can ensure that the massage stroke of the massage device 150 (for example, it can be basically consistent with the massage stroke of a seat with a separate massage device 150) and also ensure the safety protection performance of the seat belt 161 for the driver and passengers.
[0078] The seat 100 provided in this embodiment integrates not only massage function-related devices, but also a device for retracting the seat belt 161. Thus, the seat 100 not only provides a massage function but also protects the safety of occupants in dangerous situations, enabling it to meet the diverse needs of occupants and thereby improving their driving and riding experience.
[0079] In one embodiment, such as Figures 4 to 7 As shown, the drive unit 140 is located below the massage unit 150, and the winding unit 160 is located above the massage unit 150. That is, the drive unit 140 is located on the side of the massage unit 150 facing the seat cushion frame 122, and the winding unit 160 is located on the side of the massage unit 150 away from the seat cushion frame 122.
[0080] For example, the drive device 140 may be located directly below the massage device 150, and the winding device 160 may be located above the side of the massage device 150.
[0081] For example, such as Figures 4 to 7 As shown, if the terminal device is a vehicle, the seat 100 is the left seat 100 in the vehicle, and the retractable device 160 is located at the upper left of the massage device 150.
[0082] For example, if the terminal device is a vehicle, the seat 100 is the right seat 100 in the vehicle, and the retractable device 160 is located at the upper right of the massage device 150.
[0083] For example, if the terminal device is a vehicle, the seat 100 is the middle seat 100 in the vehicle, and the retractable device 160 is located at the upper right or upper left of the massage device 150.
[0084] It should be noted that the directions mentioned above are based on the direction in which the driver and passengers are sitting in their seats.
[0085] The retractor 160 is positioned higher than the drive unit 140. As a result, the seat belt 161 can utilize the mechanical advantage of "high attachment and low use" to firmly lock the most vulnerable upper body of the driver and passenger, while using gravity to ensure smoothness and reliability for daily use.
[0086] The drive unit 140 is positioned lower than the winding device 160. This lowers the center of gravity of the seat 100 and improves its stability.
[0087] In one embodiment, such as Figures 4 to 7 As shown, the massage device 150 includes a massage mechanism 151 and a kneading device 152. The massage mechanism 151 controls the kneading device 152 to perform kneading. For example, the massage mechanism 151 includes a circuit board that controls the kneading device 152 to perform kneading. The kneading device 152 is connected to the side of the massage mechanism 151 and is positioned along the sliding direction of the massage device 150. A drive device 140 and a winding device 160 are located at both ends of the kneading device 152. The positions of the drive device 140, the kneading device 152, and the winding device 160 are designed so that they do not interfere with each other. This ensures both the massage stroke of the massage device 150 and the kneading performance of the kneading device 152, as well as the safety protection performance of the seat belt 161 for the occupants. This allows the seat 100 to meet the diverse needs of the occupants, thereby further improving their driving and riding experience.
[0088] For example, such as Figures 5 to 7 As shown, the kneading device 152 includes a dual-arm structure L, which extends from the side of the massage mechanism 151 to the front of the massage mechanism 151. The dual-arm structure L is extendable and retractable along the front-back frame 112. For example, as... Figure 5 As shown, the massage device 150 includes a left-side dual-mechanical-arm structure L and a right-side dual-mechanical-arm structure L. The left-side dual-mechanical-arm structure L is connected to the left side of the massage mechanism 151 and extends from the left side of the massage mechanism 151 towards the front. The right-side dual-mechanical-arm structure L is connected to the right side of the massage mechanism 151 and extends from the right side of the massage mechanism 151 towards the front. Both the left and right dual-mechanical-arm structures L are extendable and retractable along the front-back frame 112.
[0089] Figure 8 This is a schematic diagram of another backrest frame 112 provided in an embodiment of this application. (See attached diagram.) Figure 8 As shown, when the kneading function of the seat 100 is turned off, the dual mechanical arm structure L is in a non-working state (or initial state, or storage state). The dual mechanical arm structure L is in a low position, initial position (or storage position) along the front and back direction of the backrest frame 112, or the dual mechanical arm structure L retracts to the initial position along the front and back direction of the backrest frame 112.
[0090] Figure 9 This is a schematic diagram of another backrest frame 112 provided in an embodiment of this application. (See attached diagram.) Figure 9As shown, when the kneading function of the seat 100 is turned on, the dual mechanical arm structure L is in working state (or lifting state). The dual mechanical arm structure L is in a high position, massage position (or lifting position) along the front and back direction of the backrest frame 112, or the dual mechanical arm structure L extends to the massage position along the front and back direction of the backrest frame 112.
[0091] like Figures 5 to 8 As shown, the dual-arm structure L includes a lower arm L1 and an upper arm L2, with the lower arm L1 positioned closer to one side of the seat cushion frame 122 of the seat 100 than the upper arm L2. Figure 8 As shown, when the dual-arm structure L is in a non-working state, the height h1 of the extended end of the lower robotic arm L1 in the dual-arm structure L is less than the height h2 of the extended end of the upper robotic arm L2 in the dual-arm structure L. That is, the lower robotic arm L1 is further away from the side of the backrest cover 111 facing the driver / passenger than the upper robotic arm L2. In this way, when the driver / passenger adjusts the backrest 110 of the seat 100 to a fully reclined position (including a zero-gravity position), the pressure of the extended end of the lower robotic arm L1 on the driver / passenger's back is smaller, thereby reducing the driver / passenger's feeling of foreign objects and improving the driver / passenger's comfort.
[0092] For example, the height of the extension end of the lower robotic arm L1 can be set based on the type of seat. For instance, the height of the extension end of the lower robotic arm L1 for an adult seat is greater than the height of the extension end of the lower robotic arm L1 for a child seat.
[0093] Figure 10 This is a schematic diagram of a massage device 150 provided in an embodiment of this application. For example, such as... Figure 10 As shown, the lower robotic arm L1 includes a lower rocker arm L11 and a lower massage ball head L12. One end of the lower rocker arm L11 is connected to the side of the massage mechanism 151, and the other end of the lower rocker arm L11 is connected to the lower massage ball head L12. The extended end of the lower robotic arm L1 can be understood as one end of the lower massage ball head L12 in the lower robotic arm L1.
[0094] In addition, such as Figure 10 As shown, the upper robotic arm L2 includes an upper rocker arm L21 and an upper massage ball head L22. One end of the rocker arm L21 is connected to the side of the massage mechanism 151, and the other end of the upper rocker arm L21 is connected to the upper massage ball head L22. The extended end of the upper robotic arm L2 can be understood as one end of the upper massage ball head L22 in the upper robotic arm L2.
[0095] For example, the height of the extended end of the robotic arm is related to the length of the robotic arm and the direction of its extension.
[0096] In one embodiment, such as Figure 8As shown, the lower robotic arm L1 and the upper robotic arm L2 are of equal length. Along the arrangement direction of the lower robotic arm L1 and the upper robotic arm L2, the angle between the extension direction of the lower robotic arm L1 and the massage mechanism 151 is the first angle θ1, and the angle between the extension direction of the upper robotic arm L2 and the massage mechanism 151 is the second angle θ2.
[0097] It should be understood that the angle between the extending direction of the lower robotic arm L1 and the massage mechanism 151 can be understood as the acute angle between the extending direction of the lower robotic arm L1 and the sliding direction of the massage mechanism 151. For example, as Figure 8 As shown, the angle between the extending direction of the lower robotic arm L1 and the opposite direction of the z-direction. Furthermore, the angle between the extending direction of the upper robotic arm L2 and the massage mechanism 151 can be understood as the acute angle between the extending direction of the upper robotic arm L2 and the sliding direction of the massage mechanism 151. For example, as... Figure 8 As shown, the angle between the extension direction of the upper robotic arm L1 and the z-direction.
[0098] In this design, the first angle θ1 is less than the second angle θ2. While ensuring that the lengths of the two robotic arms L are equal, the height of the extended end of the robotic arm is changed by altering the angle between the robotic arm and the massage mechanism 151. This allows for a design where, when the dual robotic arm structure L is not in operation, the height h1 of the extended end of the lower robotic arm L1 is less than the height h1 of the extended end of the upper robotic arm L2 in the dual robotic arm structure L, thereby reducing the complexity of the dual robotic arms.
[0099] In one embodiment, the difference between the second angle and the first angle is less than or equal to 2 degrees. Setting the first angle to be within 2 degrees smaller than the second angle not only ensures the kneading performance of the kneading device 152, but also reduces the foreign body sensation of the driver and passengers in a reclining position (including a zero-gravity posture), which is conducive to further improving the driving and riding experience of the driver and passengers.
[0100] In one embodiment, the distance between the extended end of the lower robotic arm L1 and the backrest cover 111 is greater than or equal to a first distance. For example, the first distance is approximately 25 millimeters. This reduces the feeling of foreign objects on the body for occupants in a fully reclining position (including a zero-gravity posture), thus further improving the driving and riding experience.
[0101] In one embodiment, the height h1 of the extended end of the lower robotic arm L1 is greater than a first height. This ensures the kneading performance of the kneading device 152, which is beneficial for further improving the driving and riding experience for passengers. Exemplarily, the first height is approximately 50 millimeters.
[0102] It should be understood that the height of the extension end of the lower robotic arm L1 can refer to the height of the extension end of the lower robotic arm L1 being higher than the extension beginning of the lower robotic arm L1.
[0103] For example, the drive unit 140 and the massage unit 150 are mounted on the same mounting base, and the massage unit 150 drives the same mounting base and the drive unit to slide relative to the backrest frame 112. In addition, the winding unit 160 is fixed to the backrest frame 112 by the mounting base.
[0104] Figure 11 This is a schematic diagram of another backrest frame 112 provided in an embodiment of this application. In one example, such as... Figure 11 As shown, the seat 100 includes a mounting base 170, which is fixed to the backrest frame 112. A drive unit 140 and a massage unit 150 are disposed on the side of the mounting base 170 opposite to the backrest frame 112, and are slidably connected to the mounting base 170. Furthermore, a winding device 160 is fixed to the side of the mounting base 170 opposite to the backrest frame 112. In other words, the drive unit 140, massage unit 150, and winding device 160 share a single mounting base 170. This single mounting base 170 allows for the sliding of the drive unit 140 and massage unit 150 relative to the backrest frame 112, while also securing the winding device 160, resulting in a simpler structure for the seat 100. Furthermore, the fact that the drive unit 140, massage unit 150, and winding device 160 are mounted on the same side of the mounting base 170 reduces the complexity of seat 100 assembly and maintenance costs.
[0105] In one example, such as Figure 8 or Figure 9 As shown, the seat 100 includes a first mounting base 171 and a second mounting base 172. The first mounting base 171 and the second mounting base 172 are located on the same side of the backrest frame 112, and are positioned along the sliding direction of the massage device 150, i.e., along the z-direction. The side of the first mounting base 171 facing away from the backrest frame 112 is used to fix the drive device 140 and the massage device 150. The massage device 150 drives the first mounting base 171 and the drive device 140 to slide relative to the backrest frame 112; that is, the first mounting base 171 and the drive device 140 can slide synchronously relative to the backrest frame 112 along with the massage device 150. The second mounting base 172 is fixed to the backrest frame 112, and the side of the second mounting base 172 facing away from the backrest frame 112 is used to fix the winding device 160. In other words, the drive device 140 and the massage device 150 each have their own mounting base, and the winding device 160 each has its own mounting base. This avoids mutual interference during the installation and operation of the massage function-related devices and the retractable seat belt 161, thereby improving the reliability of the massage function and protective performance of the seat 100.
