Description

Technical Field

[0001] This application relates to the technical field of seat protection, and more particularly to a seat assembly and vehicle. Background Technology

[0002] The rear seats in existing vehicles are typically designed solely for seating, with their structure primarily focused on supporting the passenger's body. They lack specific protective features for items placed on the seats or for young children lying down. In real-world use, rear seats are often used to store personal belongings or for young children to lie down and rest, with these items and people relying solely on the seat's own support surface to maintain their position.

[0003] In existing technologies, when a vehicle brakes, starts, or encounters road bumps that cause the vehicle body to sway, items on the rear seats are prone to sliding, falling, or even being damaged due to the lack of restraint and protection. Young children lying down in the seats may also shift due to loss of balance, posing a risk of injury. The existing structural design of the rear seats cannot solve the above safety hazards and is difficult to meet users' needs for the protection of items and the safety of young children. Utility Model Content

[0004] This application addresses, to at least some extent, one of the technical problems in the related art.

[0005] Therefore, this application aims to provide a seat assembly and vehicle that moves a protective plate by pushing a component and uses a flipping component to flip the protective plate at an angle. When protection is needed, the protective plate can move away from the seat cushion and adjust its angle in conjunction with the flipping component, thus blocking and limiting the movement of children or objects on the seat, solving the problems of children bumping into each other and objects falling off caused by the lack of protective structure in traditional seats.

[0006] To achieve the above objectives, in a first aspect, this application provides a seat assembly, comprising: A seat cushion having a front side and a rear side, wherein a receiving cavity is formed in the vertical sidewall of the front side of the seat cushion; A pushing component, wherein the pushing component is disposed within the receiving cavity; A protective plate is connected to the pushing component, which is used to drive the protective plate to move along the front-back direction of the seat cushion so that the protective plate moves closer to or away from the seat cushion. A flipping component is used to flip the protective plate.

[0007] In this technical solution, the cavity on the seat cushion provides a concealed installation space for the push assembly, effectively preventing the assembly from being exposed and taking up interior space or affecting the integrity of the seat's appearance. The push assembly can move the protective plate along the fore-and-aft direction of the seat cushion, thereby adjusting the position of the protective plate as needed. When not in use, the protective plate can be stored close to the seat cushion without interfering with the normal use of the seat; when protection is needed, the protective plate can be moved away from the seat cushion and adjusted in angle with the flip assembly to shield and limit the movement of children or items on the seat. The overall structure balances protective function with space utilization, solving the problems of children bumping into things and items falling out that are caused by the lack of protective structure in traditional seats, providing users with a flexible and safe user experience.

[0008] In some embodiments of this application, the pushing component includes: A first motor is disposed within the receiving cavity; The gear is coaxially connected to the output shaft of the first motor; A rack is slidably connected to the receiving cavity along the front-back direction of the seat cushion; a protective plate is disposed on the rack.

[0009] In this technical solution, a first motor drives a gear to rotate. The gear meshes with a rack, causing the rack to move along the front-to-back direction of the seat cushion, thereby adjusting the position of the protective plate. Gear and rack transmission offers advantages such as high transmission efficiency and stable power output, preventing jamming or misalignment of the protective plate during movement. Furthermore, gear and rack transmission provides higher positioning accuracy, ensuring the protective plate reaches the preset position. Simultaneously, gears and racks are standard components, facilitating mass procurement and assembly, reducing the manufacturing cost and maintenance difficulty of the seat assembly.

[0010] In some embodiments of this application, a guide groove is provided in the receiving cavity, and the rack is slidably connected in the guide groove.

[0011] In the technical solution, the movement direction of the rack is guided by the guide groove, which can effectively avoid rack deviation and shaking caused by uneven force or vibration, and ensure that the rack always moves stably in the front and back direction of the seat, thereby ensuring the accuracy of the protective plate position adjustment.

[0012] In some embodiments of this application, a telescopic rod is further included, one end of which is movably connected to the front side of the seat cushion, and the other end of which is slidably connected to the bottom of the protective plate.

[0013] In this technical solution, the telescopic rod provides additional support for the protective panel. When the protective panel adjusts its angle using the flipping assembly, the telescopic rod extends and retracts synchronously with the panel, consistently providing stable support and preventing bending or deformation due to the panel's own weight or external forces (such as a child leaning against it). This ensures the structural strength and protective stability of the protective panel. The telescopic rod also disperses external forces on the protective panel, reducing the load on the second motor and extending its lifespan. Furthermore, it prevents wobbling during the flipping process, ensuring the protective panel remains in a stable working state.

[0014] In some embodiments of this application, a groove is provided at the bottom of the protective plate, a slider is slidably connected in the groove, and the end of the telescopic rod near the protective plate is hinged to the slider.

[0015] In this technical solution, the telescopic rod is slidably connected to the protective plate via a slider and a groove. This design avoids interference with the telescopic rod's movement during the protective plate's flipping and movement. When the protective plate flips, the slider can slide within the groove, coordinating with the telescopic rod's extension, retraction, and angular flipping to ensure a stable connection between the telescopic rod and the protective plate without hindering its flipping motion. As the protective plate moves back and forth with the rack, the slider and groove adapt to positional changes, ensuring the telescopic rod's support remains effective. The groove and slider also constrain the telescopic rod's direction of movement, preventing misalignment and support failure, further enhancing the protective plate's operational stability.

[0016] In some embodiments of this application, the protective plate is rotatably connected to the rack, the telescopic rod is a power push rod, and the power push rod is the flipping assembly.

[0017] In this technical solution, the power push rod can directly drive the protective plate to rotate along its hinge axis with the rack through its telescopic movement. This allows for quick adjustment of the protective plate's tilt angle to accommodate the protective needs of children of different heights or items of different sizes. Furthermore, the thrust of the power push rod can be adjusted according to actual needs, ensuring that the protective plate remains stably at the target angle, preventing damage to the protective plate or seat components due to excessive thrust, and also preventing insufficient thrust from failing to provide effective support and protection.

[0018] In some embodiments of this application, the flipping component is a second motor, which is disposed on the rack; the output shaft of the second motor is connected to the protective plate.

[0019] In this technical solution, the output shaft of the second motor directly adjusts the angle of the protective plate. The output shaft of the second motor is directly connected to the protective plate, resulting in higher adjustment precision and better adaptability to different protection scenarios. Furthermore, the motor-driven method features fast response and low operating noise, improving the user experience. The motor also operates stably and reliably with a low failure rate, ensuring the long-term proper functioning of the protective plate's flipping mechanism and reducing the frequency of maintenance for the seat assembly.

[0020] In some embodiments of this application, two racks are arranged in parallel within the receiving cavity, and two second motors are respectively disposed on the two racks; the output shafts of the two second motors are arranged opposite to each other and coaxially, and the protective plate is connected to the output shafts of the two second motors.

[0021] In this technical solution, the output shafts of two second motors are opposite each other and coaxially connected to the protective plate, ensuring that both ends of the plate receive balanced driving force. This symmetrical drive structure prevents the protective plate from tilting or jamming due to uneven force at both ends during rotation, ensuring that the plate remains horizontally rotated and improving the smoothness and safety of the rotation process. Simultaneously, the two second motors provide greater rotational power, allowing for the adaptation to thicker and heavier protective plates, expanding the design range of the protective plates, and enhancing the protective capabilities of the seat assembly. Furthermore, if one second motor fails, the other can still drive the protective plate to rotate, ensuring the reliability of the structure's operation.

[0022] In some embodiments of this application, the gear meshes with two racks simultaneously; There are two first motors, and the output shafts of the two first motors are coaxially connected to both ends of the gear.

[0023] In this technical solution, the two primary motors driving the gears can output greater power, ensuring that the rack can move the protective plate and avoiding transmission jamming caused by insufficient power from a single motor. Simultaneously, the coaxial driving of the gears by the two motors ensures balanced force on the gears, preventing uneven wear or damage due to excessive force on one side, and extending the gears' service life. The synchronous meshing of the gears with the double racks ensures that the two racks always move synchronously, thus guaranteeing consistent movement speed at both ends of the protective plate, preventing plate misalignment, and ensuring accurate adjustment of the protective plate's position.

[0024] In addition, this application also provides a vehicle, including: a body, on which the above-mentioned seat assembly is disposed.

[0025] In this technical solution, the vehicle seats feature an adjustable protective panel that provides reliable protection, effectively enhancing passenger safety and ease of use. For users with young children, the seat assembly effectively protects them from injury during braking, starting, or bumpy rides. For users who need to place items in the rear seats, the protective panel prevents items from sliding and falling, meeting their daily needs. Furthermore, when not in use, the protective panel can be lowered close to the seat cushion to serve as a footrest, improving passenger comfort.

[0026] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. It should be noted that in the automotive industry, the rear seats of existing vehicles typically only serve a seating function. Their structural design is primarily focused on supporting the passenger's body, without any specific protective structures for items placed on the seats or for young children lying down. In practical use, rear seats are often used to store personal belongings or for young children to lie down and rest, with these items and people relying solely on the seat's own support surface to maintain their position.

[0031] In existing technologies, when a vehicle brakes, starts, or encounters road bumps that cause the vehicle body to sway, items on the rear seats are prone to sliding, falling, or even being damaged due to the lack of restraint and protection. Young children lying down in the seats may also shift due to loss of balance, posing a risk of injury. The existing structural design of the rear seats cannot solve the above safety hazards and is difficult to meet users' needs for the protection of items and the safety of young children.

[0032] Based on this, this application proposes a seat assembly and vehicle, in which a push component moves a protective plate, and a flip component rotates the protective plate at an angle. When protection is needed, the protective plate can move away from the seat cushion and adjust its angle in conjunction with the flip component, thus shielding and limiting the movement of children or objects on the seat, solving the problems of children bumping into each other and objects falling off caused by the lack of protective structure in traditional seats.

[0033] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0034] Please refer to all the accompanying drawings. In one illustrative embodiment of the seat assembly and vehicle of this application, the seat assembly includes: a seat cushion 100, which is used to support the user and distribute the body weight.

[0035] In some embodiments, the seat cushion 100 has a front side and a rear side, which are the same as the front and rear sides of the vehicle, with the front side of the seat cushion 100 being the front side of the vehicle and the rear side of the seat cushion 100 being the rear side of the vehicle. When a user sits on the seat cushion 100, their legs are located on the front side of the seat cushion 100.

[0036] In some embodiments, a receiving cavity 101 is formed in the vertical sidewall of the front side of the seat cushion 100. The seat assembly also includes a pushing component and a protective plate 700, with the pushing component disposed within the receiving cavity 101. The protective plate 700 is connected to the pushing component, which drives the protective plate 700 to move along the fore-and-aft direction of the seat cushion 100, so that the protective plate 700 is closer to or further away from the seat cushion 100. The receiving cavity 101 provides a concealed installation space for the pushing component, effectively preventing the component from being exposed and occupying interior space or affecting the integrity of the seat's appearance. The pushing component can drive the protective plate 700 to move along the fore-and-aft direction of the seat cushion 100, thereby adjusting the position of the protective plate 700 as needed. When not in use, the protective plate 700 can be stored close to the seat cushion 100 without interfering with the normal use of the seat.

[0037] In some embodiments, the seat assembly further includes a flipping assembly for rotating the protective panel 700.

[0038] In current technology, the seats do not have protective devices; they are used to place personal belongings or for young children to lie down and rest. When the vehicle is in motion, there may be shaking, sudden braking, or a collision. In such situations, items in the back seat may fall and be damaged, potentially injuring the child.

[0039] Therefore, through the above-mentioned solution, the protective plate 700 can be moved away from the seat cushion 100 and adjusted in angle with the flip component to provide a barrier and limit the movement of children or items on the seat. The overall structure balances protective function and space utilization, solving the problems of children bumping into each other and items falling off caused by the lack of protective structure in traditional seats, and providing users with a flexible and safe user experience.

[0040] In some embodiments, the seat assembly also includes a backrest 200, which is disposed above the seat cushion 100 and near the rear side of the seat cushion 100. The backrest 200 provides support to the passenger, avoiding muscle fatigue, back pain and other problems caused by lack of back support during long-term sitting, thus significantly improving riding comfort.

[0041] In some embodiments, the actuating component includes a first motor 500, a gear 600, and a rack 400. The first motor 500 is disposed within the receiving cavity 101; the gear 600 is coaxially connected to the output shaft of the first motor 500; the rack 400 is slidably connected to the receiving cavity 101 along the front-rear direction of the seat cushion 100; and the protective plate 700 is disposed on the rack 400. The first motor 500 drives the gear 600 to rotate, and the gear 600 meshes with the rack 400, causing the rack 400 to move along the front-rear direction of the seat cushion 100, thereby adjusting the position of the protective plate 700. The gear 600 and rack 400 transmission has the advantages of high transmission efficiency and stable power output, avoiding jamming or offset during the movement of the protective plate 700. Furthermore, the gear 600 and rack 400 transmission has higher positioning accuracy, ensuring that the protective plate 700 can reach a preset position. At the same time, the gear 600 and rack 400 are standard parts, facilitating mass procurement and assembly, reducing the manufacturing cost and maintenance difficulty of the seat assembly.

[0042] In some embodiments, a guide groove 300 is provided in the receiving cavity 101, and the rack 400 is slidably connected in the guide groove 300. The guide groove 300 guides the movement direction of the rack 400, which can effectively prevent the rack 400 from deviating or shaking due to uneven force or vibration, and ensure that the rack 400 always moves stably in the front-back direction of the seat cushion 100, thereby ensuring the accuracy of the position adjustment of the protective plate 700.

[0043] Furthermore, the guide groove 300 is a separate structure, fixedly installed within the receiving cavity 101. The separately designed guide groove 300 can be specifically designed and manufactured according to the dimensions of the rack 400 and transmission requirements, resulting in greater adaptability. In addition, this independent guide groove 300 facilitates assembly and subsequent maintenance; it can be inspected or replaced individually without disassembling the entire seat cushion 100, reducing maintenance costs.

[0044] In another embodiment, the guide groove 300 is directly formed in the inner bottom wall of the receiving cavity 101, the tooth groove of the rack 400 is set upwards, and the bottom of the rack 400 is slidably connected to the guide groove 300. The guide groove 300 provides more direct support and limiting for the bottom of the rack 400, effectively resisting the lateral displacement of the rack 400 when the vehicle bumps or the protective plate 700 is under force, ensuring the straightness of the rack 400's movement in the front-to-back direction, thereby ensuring precise adjustment and smooth movement of the protective plate 700. In addition, this structure makes higher use of the internal space of the receiving cavity 101, eliminating the need to reserve additional installation space for the independent guide groove 300, and is more suitable for compact seat designs.

[0045] It is understandable that the length direction of the guide groove 300 is the same as the length direction of the rack 400, both being opened along the front-to-back direction of the seat cushion 100.

[0046] In another embodiment, the actuating component can also be a cylinder, a hydraulic cylinder, or an electric actuator, which includes a cylinder body and an output shaft and is disposed within the receiving cavity 101. The cylinder body is fixed to the receiving cavity 101, and the output shaft is connected to the protective plate 700. Cylinders and hydraulic cylinders can provide greater thrust; electric actuators offer rapid response and precise adjustment, making it easy to achieve fine-grained control of the position of the protective plate 700.

[0047] In some embodiments, a telescopic rod 110 is also included. One end of the telescopic rod 110 is movably connected to the front side of the seat cushion 100, and the other end is slidably connected to the bottom of the protective plate 700. The telescopic rod 110 provides an additional support structure for the protective plate 700. When the protective plate 700 adjusts its angle under the action of the flipping assembly, the telescopic rod 110 can extend and retract synchronously with the flipping of the protective plate 700, always providing stable support for the protective plate 700, preventing the protective plate 700 from bending or deforming due to its own weight or external forces (such as a child leaning against it), and ensuring the structural strength and protective stability of the protective plate 700. The telescopic rod 110 can also disperse the external forces on the protective plate 700, reduce the load on the second motor 900, extend the service life of the second motor 900, and prevent the protective plate 700 from shaking during the flipping process, ensuring that the protective plate 700 always remains in a stable working state.

[0048] Understandably, without the telescopic rod 110, the protective plate 700 could be stored in the receiving cavity 101. However, with the telescopic rod 110 providing support for the protective plate 700, it cannot be stored in the receiving cavity 101. When the protective plate 700 is not needed for protection, it can be placed close to the seat cushion 100 and tilted from top to bottom away from the seat cushion 100, so that the protective plate 700 can be used as a footrest.

[0049] In some embodiments, a groove 120 is provided at the bottom of the protective plate 700, and a slider 130 is slidably connected within the groove 120. One end of the telescopic rod 110 near the protective plate 700 is hinged to the slider 130. This connection between the slider 130 and the groove 120 enables the telescopic rod 110 to be slidably connected to the protective plate 700. This design avoids interference with the movement of the telescopic rod 110 during the flipping and moving of the protective plate 700. When the protective plate 700 flips, the slider 130 can slide within the groove 120, coordinating with the extension, retraction, and angular flipping of the telescopic rod 110, ensuring a stable connection between the telescopic rod 110 and the protective plate 700 without hindering its flipping motion. When the protective plate 700 moves back and forth with the rack 400, the engagement between the slider 130 and the groove 120 adapts to positional changes, ensuring the continued effective support of the telescopic rod 110. The cooperation between the slide groove 120 and the slider 130 can also constrain the movement direction of the telescopic rod 110 to a certain extent, preventing the telescopic rod 110 from deviating and causing support failure, and further improving the working stability of the protective plate 700.

[0050] Specifically, the length direction of the slide groove 120 is the same as the length direction of the rack 400. This ensures that when the rack 400 extends the protective plate 700, the slider 130 can slide within the slide groove 120, avoiding interference and ensuring the normal operation of the structure.

[0051] In another embodiment, the telescopic rod 110 is hinged to the bottom of the protective plate 700. The other end of the telescopic rod 110 slides and is hinged to the front side of the seat cushion 100. Specifically, a groove 120 is vertically formed on the front side of the seat cushion 100, a slider 130 slides in the groove 120, and the end of the telescopic rod 110 near the seat cushion 100 is hinged to the slider 130. This still allows the telescopic rod 110 to move. Compared to having the groove 120 on the seat cushion 100, it eliminates the need for a groove in the protective plate 700, thus reducing the thickness of the protective plate 700.

[0052] In some embodiments, the protective plate 700 is rotatably connected to the rack 400, and the telescopic rod 110 is a power push rod, which is a flipping component. The power push rod can directly drive the protective plate 700 to flip along its hinge axis with the rack 400 through its telescopic movement, allowing for quick adjustment of the protective plate 700's tilt angle to accommodate the protective needs of children of different heights or items of different sizes. Furthermore, the thrust of the power push rod can be adjusted according to actual needs, ensuring that the protective plate 700 remains stably at the target angle, preventing damage to the protective plate 700 or seat components due to excessive thrust, and also preventing insufficient thrust from failing to provide effective support and protection.

[0053] Specifically, power push rods include, but are not limited to, cylinders, hydraulic cylinders, and electric push rods.

[0054] In some embodiments, the flipping component is a second motor 900, which is mounted on the rack 400; the output shaft of the second motor 900 is connected to the protective plate 700. Rotation of the output shaft of the second motor 900 directly adjusts the angle of the protective plate 700. Direct connection of the output shaft of the second motor 900 to the protective plate 700 provides higher adjustment precision and better adaptability to different protection scenarios. Furthermore, the motor drive method features fast response speed and low operating noise, improving the user experience. The motor also operates stably and reliably with a low failure rate, ensuring the long-term normal operation of the protective plate 700's flipping function and reducing the frequency of subsequent maintenance of the seat assembly.

[0055] It is worth noting that when the flipping component is the second motor 900, the telescopic rod 110 is a non-powered telescopic rod 110. This avoids conflict between the second motor 900 and the power push rod, prevents the protective plate 700 from flipping and getting stuck or deformed due to asynchronous power output between the two, and ensures smooth and stable angle adjustment of the protective plate 700.

[0056] It is understandable that when the telescopic rod 110 has no independent power, it can have a certain amount of damping to ensure that the telescopic rod 110 can support the protective plate 700.

[0057] In some embodiments, a second motor 900 is disposed at the end of the rack 400. The output shaft of the second motor 900 is connected to one side of the protective plate 700 in the width or length direction.

[0058] In some embodiments, two racks 400 are arranged in parallel within the receiving cavity 101, and two second motors 900 are respectively disposed on the two racks 400. The output shafts of the two second motors 900 are arranged opposite to each other and coaxially. The protective plate 700 is connected to the output shafts of the two second motors 900. The opposite and coaxial connection of the output shafts of the two second motors 900 to the protective plate 700 ensures that both ends of the protective plate 700 receive balanced driving force. This symmetrical drive structure avoids tilting or jamming of the protective plate 700 due to uneven force at both ends when it flips, ensuring that the protective plate 700 always remains horizontally flipped, improving the stability and safety of the flipping process. At the same time, the drive of the two second motors 900 can provide greater flipping power, which can accommodate thicker and heavier protective plates 700, expand the design range of the protective plate 700, and enhance the protective capability of the seat assembly. In addition, if one of the second motors 900 fails, the other second motor 900 can still drive the protective plate 700 to flip, ensuring the reliability of the structure operation.

[0059] In some embodiments, gear 600 simultaneously meshes with two racks 400. There are two first motors 500, and the output shafts of the two first motors 500 are coaxially connected to both ends of gear 600. The two first motors 500 driving gear 600 can output greater power, ensuring that racks 400 can move the protective plate 700, avoiding transmission jamming caused by insufficient power from a single motor. Simultaneously, the coaxial driving of gear 600 by two motors ensures balanced force on gear 600, preventing uneven wear or damage due to excessive force on one side, and extending the service life of gear 600. The synchronous meshing of gear 600 with the two racks 400 ensures that the two racks 400 always move synchronously, thereby ensuring that the moving speeds of both ends of the protective plate 700 are consistent, preventing the protective plate 700 from shifting, and ensuring the accuracy of the protective plate 700's position adjustment.

[0060] Specifically, the two racks 400 are arranged in parallel, with the ends of the two racks 400 facing the protective plate 700 in the same vertical plane, thus ensuring that the distance between the protective plate 700 and the seat cushion 100 remains the same. The tooth grooves in the two racks 400 correspond one-to-one to ensure that the moving speed and distance of the two racks 400 remain synchronized when the gear 600 rotates.

[0061] In some embodiments, the width of the protective panel 700 is the same as the width of the seat cushion 100. The protective panel 700 also includes an extension plate 800, which is hinged to one end of the protective panel 700 in the width direction. The extension plate 800 can be folded and stacked on top of the protective panel 700, and can be folded open to be flush with the protective panel 700 when needed. This allows for flexible adaptation to different width requirements. When folded, the extension plate 800 does not occupy additional space and does not affect the normal movement and flipping of the protective panel 700; when used, it is folded open to be flush with the protective panel 700, extending the protective range and adapting to wider seat cushions 100 or scenarios requiring protection of larger items. It also better wraps around the sides of a child's body, reducing the risk of lateral movement and bumps.

[0062] Furthermore, there are two extension plates 800, each hinged to one end of the protective plate 700 in the width direction. Compared to a single-sided extension, this is more suitable for seat cushions 100 of different widths or various protective scenarios.

[0063] Furthermore, this application also provides a vehicle, including a body with the aforementioned seat assembly mounted on it. The vehicle seat, through an adjustable protective panel 700, provides reliable protection, effectively improving the vehicle's passenger safety and ease of use. For users with young children, the seat assembly effectively protects them through the protective panel 700, preventing injuries during vehicle braking, starting, or bumping. For users who need to place items in the rear seats, the protective panel 700 prevents items from sliding and falling, meeting the user's daily needs. Simultaneously, when not in use, the protective panel 700 can be lowered near the seat cushion 100 as a footrest, enhancing passenger comfort.

[0064] In some embodiments, because the rear seats typically require storage space for items and for young children to ride in, the seat assembly is located in the rear of the vehicle.

[0065] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
