Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a seat cushion and seat cushion assembly. Background Technology

[0002] With the fast pace of life, electric vehicles such as electric bicycles or electric tricycles have become one of the main means of transportation for people's daily travel, often used for commuting, shopping, and other scenarios. They are characterized by low carbon emissions, environmental friendliness, and low operating costs.

[0003] Electric vehicles typically include a seat bucket with a seat cushion on top. In hot weather, especially in the summer, the surface temperature of the seat cushion will rise sharply when it is exposed to sunlight for a long time. Users, especially drivers, will feel hot and uncomfortable when sitting on the seat cushion, and may even suffer burns, which seriously affects driving comfort and safety.

[0004] Therefore, this application provides a new seat cushion and seat cushion assembly to address the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a seat cushion that can at least alleviate the technical problem in the prior art where the surface temperature of the seat cushion is too high after being exposed to the sun, which affects driving comfort and safety.

[0006] The purpose of this invention is also to provide a seat cushion assembly to further alleviate the technical problem in the prior art where the surface temperature of the seat cushion is high after being exposed to the sun, which affects driving comfort and safety.

[0007] Based on the aforementioned first objective, this utility model provides a seat cushion for connection to a seat bucket. The seat cushion includes a pad, a first pad body, and a second pad body, wherein the first pad body and the second pad body are respectively disposed on two opposite surfaces of the pad.

[0008] The pad is movably connected to the seat bucket, and the pad is movable relative to the seat bucket to allow the seat cushion to be in a first use state and a second use state; wherein, in the first use state, the second pad is located inside the seat bucket, and the first pad is away from the seat bucket; in the second use state, the first pad is located inside the seat bucket, and the second pad is away from the seat bucket.

[0009] Furthermore, the first pad includes a covering layer, which is connected to the pad plate and forms a first inner cavity with the pad plate, and a filler is disposed in the first inner cavity.

[0010] Furthermore, the second pad includes a heat insulation layer connected to the pad plate and forming a second inner cavity with the pad plate, and a moisture-conducting heat dissipation component is disposed in the second inner cavity.

[0011] Furthermore, the heat insulation layer is an aerogel felt, and the moisture-wicking and heat-dissipating component is a 3D mesh fabric.

[0012] Furthermore, the second pad also includes a reflective layer disposed on the side of the heat insulation layer away from the pad plate.

[0013] Furthermore, the reflective layer is an aluminum-plated film or a reflective coating.

[0014] Furthermore, the seat cushion also includes a rotating mechanism, through which the cushion plate is rotatably connected to the seat bucket.

[0015] Furthermore, the rotating mechanism includes a connector and a universal coupling. The connector is fixed to the seat bucket, one end of the universal coupling is fixed to the pad, and the other end is rotatably connected to the connector. The pad can drive the universal coupling to rotate relative to the connector to open and close the seat bucket.

[0016] Furthermore, the connector includes a first part fixedly connected to the seat bucket, the first part being bent toward the pad to form a second part, and the universal coupling being rotatably connected to the second part so that when the pad closes the seat bucket, the central axis of the rotating end of the universal coupling coincides with the central axis of the fixed end.

[0017] By adopting the above technical solution, the seat cushion of this utility model has at least the following beneficial effects:

[0018] It should be noted that the cushion includes a first plate surface and a second plate surface arranged opposite to each other. The first cushion body is disposed on the first plate surface, and the second cushion body is disposed on the second plate surface. When the seat cushion is in the first use state, the second cushion body is hidden inside the seat bucket. At this time, the first cushion body is away from the seat bucket and can serve as the actual seating surface for the user. When the seat cushion is in the second use state, the first cushion body is hidden inside the seat bucket. At this time, the second cushion body is away from the seat bucket and can serve as the actual seating surface for the driver.

[0019] This configuration allows, for example, the first cushion in its first usage state to serve as a regular cushion, providing basic daily seating support. When the first cushion fails to provide comfortable seating support due to sun exposure or other reasons, the cushion can be moved relative to the seat bucket to put the seat cushion into a second usage state. In this state, the second cushion can serve as the actual seating surface for the driver. Since the seat cushion is in the first usage state when exposed to the sun, and the second cushion is hidden inside the seat bucket, when the seat cushion is switched to the second usage state, the second cushion has not been exposed to the sun and can provide more comfortable seating support for the user. Therefore, the seat cushion of this embodiment alleviates the technical problem in the prior art where the surface temperature of the seat cushion is high after sun exposure, affecting driving comfort and safety.

[0020] Based on the second objective mentioned above, this utility model provides a seat cushion assembly, which includes a seat bucket and the seat cushion, wherein the pad of the seat cushion is movably connected to the seat bucket.

[0021] By adopting the above technical solution, the seat cushion assembly of this utility model has at least the following beneficial effects:

[0022] By incorporating the aforementioned seat cushion within the seat cushion assembly, the seat cushion assembly consequently possesses all the advantages of the aforementioned seat cushion, which will not be elaborated upon here. Attached Figure Description

[0042] Example 1

[0043] Please see Figure 1 and combined Figure 4 This embodiment provides a seat cushion for connection to a seat bucket 1. The seat cushion includes a pad 2, a first pad 3 and a second pad 4, which are respectively disposed on two opposite surfaces of the pad 2.

[0044] The pad 2 is movably connected to the seat bucket 1, and the pad 2 can move relative to the seat bucket 1 to allow the seat cushion to be in a first use state and a second use state; wherein, please refer to Figure 4 In the first usage state, the second cushion 4 is located inside the seat 1, and the first cushion 3 is away from the seat 1; please refer to Figure 5 In the second usage state, the first cushion 3 is located inside the seat 1, and the second cushion 4 is away from the seat 1.

[0045] Specifically, the cushion 2 includes a first plate surface and a second plate surface arranged opposite to each other. The first cushion body 3 is disposed on the first plate surface, and the second cushion body 4 is disposed on the second plate surface. When the seat cushion is in the first use state, the second cushion body 4 is hidden inside the seat bucket 1. At this time, the first cushion body 3 is away from the seat bucket 1 and can serve as the actual seating surface for the user. When the seat cushion is in the second use state, the first cushion body 3 is hidden inside the seat bucket 1. At this time, the second cushion body 4 is away from the seat bucket 1 and can serve as the actual seating surface for the driver.

[0046] This configuration allows, for example, the first cushion 3 in the first usage state to be used as a regular cushion, providing basic daily seating support. When the first cushion 3 cannot provide comfortable seating support due to sun exposure or other reasons, the cushion plate 2 can be moved relative to the seat bucket 1 to put the seat cushion in a second usage state. At this time, the second cushion 4 can serve as the actual seating surface for the driver. Since the seat cushion is in the first usage state when exposed to the sun, and the second cushion 4 is hidden inside the seat bucket 1, when the seat cushion is switched to the second usage state, the second cushion 4 has not been exposed to the sun and can provide more comfortable seating support for the user. Therefore, the seat cushion of this embodiment alleviates the technical problem in the prior art where the surface temperature of the seat cushion is high after sun exposure, affecting driving comfort and safety.

[0047] Preferably, please refer to Figure 2 and Figure 3 In this embodiment, the first pad 3 includes a covering layer 31, which is connected to the pad plate 2 and forms a first inner cavity with the pad plate 2. A filler 32 is disposed in the first inner cavity.

[0048] Optionally, the covering layer 31 can be a leather layer or a fabric layer. The leather layer can be artificial leather, and the filling 32 can be high-density sponge. The artificial leather wrapping the sponge serves as the first cushion 3, which can be used as a regular seating surface, providing basic seating support and comfort.

[0049] Preferably, please refer to Figure 2 and Figure 3 In this embodiment, the second pad 4 includes a heat insulation layer 42, which is connected to the pad 2 and forms a second inner cavity with the pad 2. A moisture-conducting heat dissipation component 43 is provided in the second inner cavity.

[0050] Among them, the moisture-wicking heat dissipation component 43 is used to promote heat dissipation and air circulation, keeping the user's contact surface cool, and the heat insulation layer 42 is used to block heat from being transferred downwards. With this configuration, the second cushion 4 can serve as a special sun-protection and cooling seating surface in summer.

[0051] Optionally, the heat insulation layer 42 is an aerogel felt, and the moisture-wicking and heat-dissipating component 43 is a 3D mesh fabric.

[0052] Preferably, please refer to Figure 2 and Figure 3 In this embodiment, the second pad 4 also includes a reflective layer 41 disposed on the side of the heat insulation layer 42 away from the pad 2.

[0053] The reflective layer 41 can effectively reflect the radiation of sunlight, reduce the absorption of sunlight by the second cushion 4, and reduce the heating rate of the second cushion 4 to a certain extent.

[0054] Optionally, the reflective layer 41 is an aluminum-plated film or a reflective coating.

[0055] With this design, the second cushion 4 serves as a dedicated seating surface for summer. Through the combined application of highly reflective, heat-insulating, and heat-dissipating materials, it significantly reduces the surface temperature of the seat, preventing users from being burned and greatly improving the comfort and safety of riding in summer.

[0056] Preferably, in this embodiment, the seat cushion further includes a rotating mechanism, and the cushion plate 2 is rotatably connected to the seat bucket 1 through the rotating mechanism.

[0057] In other words, the pad 2 can rotate relative to the seat bucket 1 to switch between the first and second use states of the seat cushion, so that the first cushion body 3 and the second cushion body 4 can be chosen to face the user as the sitting surface. This setting makes it more convenient to switch the use state of the seat cushion and is conducive to the promotion of the use of the seat cushion.

[0058] Preferably, please refer to Figure 4 and Figure 5 In this embodiment, the rotating mechanism includes a connector 5 and a universal coupling 6. The connector 5 is fixed to the seat 1, one end of the universal coupling 6 is fixed to the pad 2, and the other end is rotatably connected to the connector 5. The pad 2 can drive the universal coupling 6 to rotate relative to the connector 5 to open and close the seat 1.

[0059] This configuration allows the universal coupling 6 to rotate relative to the connecting member 5 via the pad 2, enabling the opening and closing of the seat bucket 1. For example, if the pad 2 rotates the universal coupling 6 relative to the connecting member 5 away from the seat bucket 1, the seat bucket 1 can be opened, allowing items to be placed or removed from the space inside the seat bucket 1. If the pad 2 rotates the universal coupling 6 relative to the connecting member 5 towards the seat bucket 1, the seat bucket 1 can be closed, allowing the user to sit on the seat and drive the vehicle.

[0060] When it is necessary to change the usage state of the seat cushion, the pad 2 can drive the universal coupling 6 to rotate relative to the connecting piece 5 away from the seat bucket 1 to lift the seat cushion. At this time, the seat bucket 1 is opened. Then, the pad 2 drives the rotating end 61 of the universal coupling 6 to flip relative to the fixed end 62, so that the pad 2 flips relative to the seat bucket 1, which can exchange the positions of the first pad body 3 and the second pad body 4, thereby allowing the seat cushion to switch between the first usage state and the second usage state.

[0061] Therefore, the seat cushion of this embodiment can be manually flipped 180° to make the seat cushion have a double-sided function, which can effectively meet the usage needs of different seasons (especially high temperature in summer). The seat cushion has a simple structure and the operation of changing the seat cushion state is convenient. It can effectively solve the problem of high temperature of the seat cushion in summer, and there is no need to store accessories. It is both comfortable and beautiful.

[0062] Preferably, please refer to Figure 7 and Figure 8 and combined Figure 6 In this embodiment, the connector 5 includes a first part 51 fixedly connected to the seat bucket 1. The first part 51 is bent toward the pad plate 2 to form a second part 52. The universal coupling 6 is rotatably connected to the second part 52 so that when the pad plate 2 closes the seat bucket 1, the central axis of the rotating end 61 of the universal coupling 6 coincides with the central axis of the fixed end 62.

[0063] With this configuration, when the pad 2 closes the seat 1 via the connector 5, the central axis of the rotating end 61 of the universal coupling 6 coincides with the central axis of the fixed end 62, thereby making the state of the pad 2 closing the seat 1 more stable, and making it more comfortable for the user to sit on the seat and drive the vehicle.

[0064] It should be added that the seat cushion of this embodiment can be improved based on the conventional seat cushion in the prior art. The main improvement is the addition of a rotating mechanism and a second cushion body 4 set on the other side of the cushion plate 2. The structure is relatively simple and reliable, easy to produce and integrate into existing electric vehicles, and the increase in manufacturing cost is limited.

[0065] Example 2

[0066] Embodiment 2 provides a seat cushion assembly, which includes the seat cushion of Embodiment 1. The technical features of the seat cushion disclosed in Embodiment 1 are also applicable to this embodiment. The technical features of the seat cushion disclosed in Embodiment 1 will not be described again.

[0067] Please see Figure 4 and Figure 5 The seat cushion assembly provided in this embodiment includes a seat bucket 1 and the aforementioned seat cushion, with the seat cushion plate 2 movably connected to the seat bucket 1.

[0068] It should be noted that the seat cushion assembly can be used in electric bicycles or electric tricycles and other electric vehicles. In the seat cushion assembly, since the seat cushion plate 2 can move relative to the seat bucket 1, the seat cushion can be in a first use state and a second use state, so the seat cushion can be used for two purposes.

[0069] This configuration allows, for example, the first cushion 3 in the first usage state to be used as a regular cushion, providing basic daily seating support. When the first cushion 3 cannot provide comfortable seating support due to sun exposure or other reasons, the cushion plate 2 can be moved relative to the seat bucket 1 to put the seat cushion in a second usage state. At this time, the second cushion 4 can serve as the actual seating surface for the driver. Since the seat cushion is in the first usage state when exposed to the sun, and the second cushion 4 is hidden inside the seat bucket 1, when the seat cushion is switched to the second usage state, the second cushion 4 has not been exposed to the sun and can provide more comfortable seating support for the user. Therefore, the seat cushion of this embodiment alleviates the technical problem in the prior art where the surface temperature of the seat cushion is high after sun exposure, affecting driving comfort and safety.

[0070] The seat cushion assembly of this embodiment has the advantages of the seat cushion of Embodiment 1, which have been described in detail in Embodiment 1 and will not be repeated here.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
