Description

Technical Field

[0001] This utility model relates to the field of RV technology, specifically to a multi-functional seat and vehicle. Background Technology

[0002] With the fast pace of modern life and the improvement of living standards, more and more people are choosing to travel outdoors in motorhomes to enjoy a free, convenient, and comfortable travel experience. As a special type of vehicle that integrates living and transportation, a motorhome not only possesses the basic functions of a vehicle but also incorporates various convenient facilities of home life, such as beds, sofas, kitchens, and bathrooms, allowing travelers to enjoy the warmth and comfort of home even outdoors. However, the interior space layout of a motorhome faces many challenges.

[0003] Due to the limited size of RVs, their interior space is relatively small. Achieving a reasonable division of functional areas within this limited space has become a major challenge in RV design. To address this issue, RV manufacturers generally use partitions to divide the interior space, clearly distinguishing different functional areas such as bedrooms, living rooms, kitchens, and bathrooms. However, most existing RV partitions are fixed designs, meaning they cannot be easily moved or removed once installed. While these fixed partitions achieve functional area division to some extent, they also bring many inconveniences. For example, when a functional area (such as the bathroom) is not in use, the fixed partition still occupies space, making the overall interior space of the RV feel more cramped, less bright, and restricting the traveler's movement. Furthermore, fixed partitions can also lead to poor ventilation inside the RV, affecting the comfort of the living environment.

[0004] In addition, existing RV seats generally suffer from limited functionality and simple facilities, and the resting area provided by existing RV seats is limited, resulting in low space utilization.

[0005] Therefore, existing technologies need further development. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a multifunctional seat and vehicle to solve the technical problems of inflexible interior space division and limited use of functional areas in RVs in related technologies.

[0007] To achieve the above technical objectives, the present invention adopts the following technical solution: a multifunctional chair is provided, comprising: a chair body; a backrest assembly, the backrest assembly including a first fixing frame and a second fixing frame, the first fixing frame being provided with a fixing plate, the second fixing frame being vertically and vertically arranged relative to the first fixing frame, the second fixing frame being provided with a lifting plate, and when the second fixing frame is raised, the lifting plate rises accordingly, so that the fixing plate and the lifting plate form a partition; wherein, the side of the first fixing frame near the chair body is connected to the chair body, and the side of the fixing plate near the chair body is provided with a backrest for the user to lean against.

[0008] Furthermore, the chair back assembly includes a drive assembly for driving the second fixed frame to rise and fall. The drive assembly includes a motor and a lead screw. A nut is threaded onto the lead screw and is fixedly connected to the second fixed frame. The motor drives the lead screw to rotate, thereby causing the nut to move along the axial direction of the lead screw, so as to realize the second fixed frame moving up and down along the first fixed frame.

[0009] Furthermore, the motor is fixed to the bottom of the first fixed frame, the lead screw is vertically mounted on the first fixed frame, and the output end of the motor passes through the first fixed frame and is connected to the lead screw to drive the lead screw to rotate.

[0010] Furthermore, there are two first fixed frames, which are spaced apart, and two fixed plates, each of which is installed on a corresponding first fixed frame, thereby forming a corridor between the two first fixed frames.

[0011] Furthermore, there are two lifting platforms, which are spaced apart on the second fixed frame to form a window between the two lifting platforms.

[0012] Furthermore, the drive components are configured in two groups, with each group of drive components mounted on two first fixed brackets.

[0013] Furthermore, the chair back assembly also includes two sets of guide components, each set of guide components being configured in conjunction with a corresponding drive component; the guide component includes a guide rod and a sleeve rod, the sleeve rod being fixed on the first fixed frame and arranged parallel to the lead screw, the guide rod being slidably disposed within the sleeve rod and connected to the second fixed frame; when the second fixed frame drives the lifting plate to move, the end of the guide rod away from the second fixed frame moves within the sleeve rod, thereby limiting the second fixed frame.

[0014] Furthermore, there are two guide rods, which are respectively set on both sides of the lead screw and maintain an equal distance from the lead screw.

[0015] Furthermore, the chair back assembly also includes a roller blind assembly, which includes a roller and a roller blind. The roller is located inside the window, and one end of the roller blind is connected to the roller and can be rolled up or unrolled around the roller to cover or open the window.

[0016] Furthermore, a telescopic plate is also provided on the first fixed frame. The telescopic plate is movably arranged relative to the first fixed frame so that it can be moved between the two fixed plates when needed, thereby blocking the corridor.

[0017] Furthermore, a suspension frame is provided between the two lifting platforms, and a flip-up plate is connected below the suspension frame. The suspension frame is located inside the window, and the flip-up plate is rotatably set relative to the suspension frame. When the second fixed frame is at its lowest position, the flip-up plate can be used as a backrest.

[0018] Furthermore, there are two seat bodies, which are spaced apart and connected to two first fixed frames respectively, forming at least a partial corridor between the two seat bodies; the seat also includes a seat folding plate, which is movably connected to the two seat bodies respectively. The seat folding plate has a folded state and a connected state connected to the two seat bodies. When the seat folding plate is in the connected state, both ends of the seat folding plate are connected to the two seat bodies respectively.

[0019] Furthermore, the seat body includes a first extension module, which includes an extension box slidably connected to the seat body. The interior of the seat body accommodates at least a portion of the extension box, which is movably disposed along the extension direction of the seat body to leave or enter the interior of the seat body.

[0020] Furthermore, the seat body includes a second extension module, which includes a leg rest that is rotatably connected to the seat body. The leg rest has a retracted state and a raised state connected to the seat body. When the leg rest is in the raised state, it is used to support the passenger's body.

[0021] A vehicle comprising the aforementioned multi-functional seat.

[0022] Beneficial effects:

[0023] 1. The partition between the first and second movable areas can be flexibly adjusted by raising and lowering the second fixed frame. When it is necessary to separate the two areas, raising the second fixed frame and the lifting platform will form an effective partition; when a larger space or a more open layout is needed, lowering the second fixed frame and the lifting platform will free up space and achieve flexible use of the space.

[0024] 2. In the multifunctional seat of this embodiment, a liftable partition is combined with the seat. Through the design of the liftable panel, the interior space layout of the RV can be flexibly adjusted according to actual needs. When a certain functional area is not needed, the liftable panel can be lowered to free up space, making the interior of the RV more spacious, improving space utilization and range of motion, and solving the technical problems of inflexible interior space division and limited use of functional areas in related technologies.

[0025] 3. In the vehicle of this embodiment, a multi-functional seat is provided, which combines a liftable partition with the seat. The seat not only has the function of allowing people to sit and rest, but the back of the seat also has the function of a partition. At the same time, the seat can be extended into a bed. The interior space layout of the RV can be flexibly adjusted according to actual needs, which solves the technical problems of inflexible interior space division and limited use of functional areas in related technologies, and improves the space utilization rate of vehicles such as RVs.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] According to an embodiment of this utility model, a multifunctional seat and vehicle are provided. Please refer to [link / reference]. Figures 1 to 9 The invention includes: a multifunctional chair, characterized in that it includes: a chair body 10; a backrest assembly, the backrest assembly including a first fixing frame 1 and a second fixing frame 3, the first fixing frame 1 being provided with a fixing plate 11, the second fixing frame 3 being vertically and vertically disposed relative to the first fixing frame 1, the second fixing frame 3 being provided with a lifting plate 31, when the second fixing frame 3 is raised, the lifting plate 31 rises accordingly, so that the fixing plate 11 and the lifting plate 31 form a partition; wherein, the side of the first fixing frame 1 near the chair body 10 is connected to the chair body 10, and the side of the fixing plate 11 near the chair body 10 is provided with a backrest 20 for the user to lean against.

[0040] Specifically, when the multifunctional seat of this embodiment is applied to vehicles such as RVs, the multifunctional seat not only has the function of providing a place for people to sit and rest, but the backrest of the multifunctional seat also has the function of partitioning, that is, dividing the interior of the RV into multiple areas. For example, in this embodiment, the first fixing frame 1 is set inside the RV, one side of the fixing plate 11 is the first active area 21, and the other side of the fixing plate 11 is the second active area 22. The second fixing frame 3 is raised and lowered relative to the first fixing frame 1. The second fixing frame 3 is provided with a lifting plate 31. When the second fixing frame 3 is raised, the lifting plate 31 rises accordingly, so that the fixing plate 11 and the lifting plate 31 form a partition, thereby separating the first active area 21 from the second active area 22.

[0041] The partition between the first movable area 21 and the second movable area 22 can be flexibly adjusted by raising and lowering the second fixed frame 3. When it is necessary to separate the two areas, raising the second fixed frame 3 and the lifting plate 31 can form an effective partition (e.g., Figure 4 and Figure 5 As shown); when more space or a more open layout is needed, lowering the second fixed frame 3 and the lifting platform 31 can free up space and achieve flexible use of the space (such as...). Figure 6 and Figure 7 (As shown).

[0042] In this embodiment of the multifunctional seat, a liftable partition is integrated with the seat. The design of the liftable partition allows for flexible adjustment of the interior space layout of the RV according to actual needs. When a certain functional area is not needed, the liftable partition can be lowered to free up space, making the RV interior more spacious, improving space utilization and range of motion, and solving the technical problems of inflexible interior space division and limited use of functional areas in related technologies.

[0043] Furthermore, by combining the liftable partition with the original seats inside the vehicle, the partition's footprint is further reduced, avoiding taking up too much interior space. This allows the seats to have multiple functions, creating a multifunctional seat that greatly improves the space utilization of vehicles such as motorhomes.

[0044] In the multifunctional seat of this embodiment, see Figure 3 The chair back assembly includes a drive assembly 4, which drives the second fixed frame 3 to rise and fall. The drive assembly 4 includes a motor 41 and a lead screw 42. A nut 43 is threaded onto the lead screw 42 and is fixedly connected to the second fixed frame 3. The motor 41 drives the lead screw 42 to rotate, thereby causing the nut 43 to move axially along the lead screw 42, thus enabling the second fixed frame 3 to move up and down along the first fixed frame 1. The drive assembly 4, with its motor 41 and lead screw 42 structure, makes the raising and lowering operation of the second fixed frame 3 simple and convenient. Users only need to control the start and stop of the motor 41 to raise and lower the lifting plate 31, without manual operation or starting the RV, achieving independent control of the liftable partition and greatly improving ease of use.

[0045] In the multifunctional seat of this embodiment, see Figure 3The motor 41 is fixed to the bottom of the first fixed frame 1, and the lead screw 42 is vertically mounted on the first fixed frame 1. The output end of the motor 41 passes through the first fixed frame 1 and connects to the lead screw 42 to drive the lead screw 42 to rotate. Because the motor 41 is located at the bottom of the RV and the lead screw 42 is vertically mounted, this layout helps enhance the stability of the entire liftable partition structure, ensuring that there will be no swaying or tilting during lifting. This design allows the motor 41 and lead screw 42 to be tightly integrated within the first fixed frame 1, reducing the need for additional space and maintaining the neatness and efficient use of the RV's interior space.

[0046] In the multifunctional seat of this embodiment, see Figure 3 There are two first fixing frames 1, which are spaced apart. There are two fixing plates 11, which are respectively installed on each of the first fixing frames 1, thereby forming a corridor 12 between the two first fixing frames 1.

[0047] Specifically, by setting up a corridor 12, the first activity area 21 and the second activity area 22 can be connected to each other through the corridor 12. By forming a corridor 12 between the two first fixed frames 1, not only is the connection between the first activity area 21 and the second activity area 22 realized, but the interior space of vehicles such as motorhomes is also fully utilized.

[0048] In the multifunctional seat of this embodiment, see Figure 3 There are two lifting plates 31, which are spaced apart on the second fixed frame 3 so that a window 32 is formed between the two lifting plates 31.

[0049] Specifically, when the fixed plate 11 and the lifting plate 31 form a partition, the window 32 is used to enable visual communication between the first active area 21 and the second active area 22. The design of the window 32 ensures that even if the first active area 21 and the second active area 22 are separated by a partition, a certain degree of visual communication can still be maintained between the two areas.

[0050] In the multifunctional seat of this embodiment, see Figure 3 The drive assembly 4 is configured as two sets, with each set of drive assembly 4 mounted on two first fixed frames 1 respectively. The two sets of drive assemblies 4 can cooperate with each other to share the weight and load of the lifting partition, avoiding the risk of failure of a single drive assembly due to excessive pressure, and also improving the lifting efficiency of the lifting partition.

[0051] In the multifunctional seat of this embodiment, see Figure 3The chair back assembly also includes two sets of guide components 5, each set of guide components 5 being configured in conjunction with a corresponding drive component 4. Each guide component 5 includes a guide rod 51 and a sleeve rod 52. The sleeve rod 52 is fixed to the first fixed frame 1 and is parallel to the lead screw 42. The guide rod 51 is slidably disposed within the sleeve rod 52 and connected to the second fixed frame 3. When the second fixed frame 3 moves the lifting plate 31, the end of the guide rod 51 away from the second fixed frame 3 moves within the sleeve rod 52, thereby limiting the movement of the second fixed frame 3. The sliding of the guide rod 51 within the sleeve rod 52 restricts the movement trajectory of the second fixed frame 3, ensuring that the second fixed frame 3 can rise and fall along a predetermined path. The guide components 5 not only provide guidance but also enhance the load-bearing capacity of the lifting partition, enabling it to remain stable during lifting.

[0052] In the multifunctional seat of this embodiment, see Figure 1 There are two guide rods 51, which are respectively set on both sides of the lead screw 42 and maintain an equal distance from the lead screw 42. The arrangement of two guide rods 51 can make the force on the lifting partition more balanced during the lifting process. When the lifting partition is under load, the two guide rods 51 can share the pressure, avoiding the risk of failure of a single guide rod due to excessive pressure.

[0053] In the multifunctional seat of this embodiment, see Figure 3 and Figure 5 The chair back assembly also includes a roller blind assembly 6, which includes a roller 61 and a roller blind 62. The roller 61 is disposed inside the window 32, and one end of the roller blind 62 is connected to the roller 61 and can be rolled up or unrolled around the roller 61 to cover or open the window 32.

[0054] Specifically, by setting up a roller blind assembly 6, the visual connection between the first activity area 21 and the second activity area 22 is adjusted. The roller blind assembly 6 allows users to flexibly block or open the window 32 as needed, thereby adjusting the visual connection between the first activity area 21 and the second activity area 22. This design increases the flexibility and privacy of the RV's interior space, allowing users to adjust it according to different scenarios and needs.

[0055] In the multifunctional seat of this embodiment, see Figure 5 and Figure 7 The first fixed frame 1 is also provided with a telescopic plate 13, which is movably arranged relative to the first fixed frame 1 so that the telescopic plate 13 can be moved between the two fixed plates 11 when needed, thereby blocking the corridor 12.

[0056] Specifically, by installing a retractable panel 13, the corridor 12 is blocked, thus achieving the closed isolation between the first activity area 21 and the second activity area 22. The design of the retractable panel 13 allows the interior space of the RV to be flexibly adjusted as needed. When it is necessary to close off the two activity areas, simply move the retractable panel 13 between the fixed panels 11; when it is necessary to restore the passageway function, move the retractable panel 13 back to its original position. This design improves the utilization rate and flexibility of the RV's interior space.

[0057] In the multifunctional seat of this embodiment, see Figure 9 A suspension bracket 33 is provided between the two lifting platforms 31, and a flip-up plate 34 is connected below the suspension bracket 33. The suspension bracket 33 is located inside the window 32, and the flip-up plate 34 is rotatably set relative to the suspension bracket 33. When the second fixed bracket 3 is at its lowest position, the flip-up plate 34 can be used as a backrest. When the kitchen and bathroom area is not in use, the corridor 12 is closed, the second fixed bracket 3 is lowered to its lowest position, the suspension bracket 33 is located inside the corridor 12, and the flip-up plate 34 is used as a seat backrest. When the corridor 12 needs to be used temporarily, the flip-up plate 34 is rotated to open the corridor 12 passage. The operation is simple and convenient.

[0058] In the multifunctional seat of this embodiment, see Figure 1 There are two seat bodies 10, which are spaced apart and connected to two first fixing frames 1 respectively. At least a partial corridor 12 is formed between the two seat bodies 10. The seat also includes a seat folding plate 101, which is disposed between the two seat bodies 10. The seat folding plate 101 is movably connected to the two seat bodies 10 respectively. The seat folding plate 101 has a folded state and a connected state connected to the two seat bodies 10. When the seat folding plate 101 is in the connected state, both ends of the seat folding plate 101 are connected to the two seat bodies 10 respectively. In this way, by setting up the seat folding panel 101 and switching the connection state between the seat folding panel 101 and the seat body 10, the aisle 12 can be opened or closed. When the seat folding panel 101 is in the connected state, both ends of the seat folding panel 101 are connected to the two seat bodies 10 respectively, which lengthens the seat, increases the number of seats available, and increases the space utilization of the vehicle. At this time, the aisle is closed. When the seat folding panel 101 is in the folded state, the seat folding panel 101 is folded or removed, and there is no obstruction between the two seat bodies 10. At this time, the aisle is opened.

[0059] In some embodiments, the seat folding panel 101 is an independently set structure that can be flexibly removed or installed between two seat bodies 10, thereby facilitating the opening or closing of the corridor.

[0060] In some embodiments, the seat folding plate 101 is rotatably connected to any seat body 10 via a hinge or hinge, and the connection state of the seat folding plate 101 is switched by rotating the seat folding plate 101.

[0061] In the multifunctional seat of this embodiment, see Figure 2 The seat body 10 includes a first extension module, which includes an extension box 102 slidably connected to the seat body 10. At least a portion of the extension box 102 is housed inside the seat body 10. The extension box 102 is movably disposed along the extending direction of the seat body 10 to leave or enter the interior of the seat body 10. Thus, by moving the extension box 102, it can be pulled out of the seat body 10, thereby extending the overall length of the seat body 10. In this embodiment, the seat can be converted into a bed, realizing the functional extension of the seat into a bed. This structural design effectively increases the number of beds inside vehicles such as RVs, thereby increasing the resting space inside the vehicle and improving the utilization efficiency of the interior space.

[0062] In some embodiments, the first expansion module further includes a locking structure 104, which includes a first locking member and a second locking member. The first locking member is disposed on the seat body 10 and has a latch for receiving the second locking member. The second locking member is disposed on the expansion box 102. When the expansion box 102 moves into the interior of the seat body 10, the first locking member and the second locking member are locked together, thereby preventing unnecessary movement of the expansion box 102 and improving driving safety.

[0063] In the multifunctional seat of this embodiment, see Figure 1 The seat body 10 includes a second extension module, which includes a leg rest 103 rotatably connected to the seat body 10. The leg rest 103 has a folded state and a raised state connected to the seat body. When the leg rest 103 is in the raised state, it is used to support the passenger's body. In this way, by setting the leg rest 103, the overall length of the seat body 10 can be increased. At this time, the seat in this embodiment can be used as a bed, enabling the seat to be extended into a bed. This can increase the number of beds inside vehicles such as RVs, thereby increasing the rest space inside the vehicle.

[0064] Applying the seats of this embodiment to a motorhome, for example, the first activity area 21 can be set as a leisure area where passengers can rest on the seat body 10, and the second activity area 22 can be set as a kitchen and bathroom area, with a toilet 8 on one side and a kitchen cabinet 9 on the other. When the kitchen and bathroom area is not in use, the corridor 12 is closed, the seat folding panel 101 is switched to the connected state, and the telescopic panel 13 is moved between the two fixed panels 11 to serve as the backrest of the seat folding panel 101, thereby improving comfort (e.g., ...). Figure 5 and Figure 7 (As shown); when it is necessary to enter the kitchen and bathroom area, the telescopic panel 13 is retracted into the first fixed frame 1, and the seat folding panel 101 is switched to the folded state, so that the corridor is open for pedestrian passage (as shown). Figure 3 and Figure 8 (As shown).

[0065] See Figure 3 , Figure 5 , Figure 7 and Figure 8 A soft pillow 7 is installed on the top of the second mounting bracket 3. When the second mounting bracket 3 rises to the top of the RV, the soft pillow 7 contacts the RV roof surface, forming a cushion. When the second mounting bracket 3 is lowered to the bottom, the soft pillow 7 serves as a seat backrest. When the lifting platform 31 rises to the top of the RV, the soft pillow 7 contacts the RV roof surface, forming an effective cushioning layer. This reduces noise and vibration caused by the lifting platform directly impacting the RV roof surface, protecting the RV roof and lifting partition from damage. When the lifting platform 31 is lowered to the bottom, the soft pillow 7 can be used as a backrest, providing additional comfort support for passengers inside the RV. This helps improve the rest and sleep experience for passengers inside the RV.

[0066] A vehicle comprising the aforementioned seats.

[0067] In this embodiment of the vehicle, a multi-functional seat is provided, which combines a liftable partition with the seat. The seat not only has the function of providing a place for people to sit and rest, but the back of the seat also has the function of a partition. At the same time, the seat can be extended to become a bed. The interior space layout of the RV can be flexibly adjusted according to actual needs, which solves the technical problems of inflexible interior space division and limited use of functional areas in related technologies, and improves the space utilization rate of vehicles such as RVs.
