Description

Technical Field

[0001] This application relates to the technical field of vehicle seat cushion accessories, and in particular to seat cushion protective covers, seat cushion protective cover rolls, and vehicles. Background Technology

[0002] As an important tool for short-distance urban travel, shared bicycles rely on technologies such as the Internet of Things, artificial intelligence, and big data to achieve efficient and environmentally friendly transportation services. From a social perspective, they effectively alleviate urban traffic congestion, reduce carbon emissions, and serve as an important supplement to public transportation connections.

[0003] However, the high frequency of use of shared bicycles also brings hygiene and safety risks. Because bicycle seats frequently come into contact with different users and lack effective disinfection mechanisms, microorganisms (such as bacteria and fungi) and viruses can be transmitted through skin contact, leading to a risk of cross-infection. Sweat or stains easily remain on the surface of shared bicycle seats, further exacerbating hygiene risks, necessitating an innovative design that balances convenience with health and safety.

[0031] As an important tool for short-distance urban travel, shared bicycles rely on technologies such as the Internet of Things, artificial intelligence, and big data to achieve efficient and environmentally friendly transportation services. From a social perspective, they effectively alleviate urban traffic congestion, reduce carbon emissions, and serve as an important supplement to public transportation connections.

[0032] However, the high frequency of use of shared bicycles also brings hygiene and safety risks. Because bicycle seats frequently come into contact with different users and lack effective disinfection mechanisms, microorganisms (such as bacteria and fungi) can be transmitted through skin contact, leading to a risk of cross-infection. Sweat or stains easily remain on the surface of shared bicycle seats, further exacerbating hygiene risks, necessitating an innovative design that balances convenience with health and safety.

[0033] To address the related technical problems, this application provides a vehicle including a seat cushion and a seat cushion cover. The seat cushion cover is used to cover the seat cushion, thereby reducing the risk of microbial migration on the seat cushion. Furthermore, the vehicle provided in this application may also include a voice prompt device, which can play a preset voice message to indicate that the vehicle is equipped with a seat cushion cover for use. Exemplarily, the voice prompt device may include a communication element and a controller. The communication element can communicate with a mobile terminal and receive instructions from the mobile terminal. These instructions may be unlocking instructions. Simultaneously with unlocking the vehicle, the controller can also control the voice prompt device to issue a prompting voice message, such as "Unlocked, please use the seat cushion cover." Of course, the voice message can also be other voice messages, and different voice messages can be used depending on the actual situation. This application does not limit the specific voice message used.

[0034] The vehicles referred to here can be electric bicycles, scooters, electric skateboards, folding electric bicycles, shared bicycles, and shared electric bicycles, etc., which have small seats. This application is more inclined to use them in environments with shared vehicles, because they may need to come into frequent contact with different users, and the risk of disease transmission is greater. Of course, they can also be used in other types of vehicles to reduce the risk of microbial transmission.

[0035] To address the related technical issues, this application also provides a seat cover roll, which includes multiple seat covers as described below. The multiple seat covers are connected in sequence, and a pre-tear string is provided between two adjacent seat covers. When a single seat cover is needed, it is convenient to tear off the required number of seat covers and put them on the seat.

[0036] To address the related technical problems, this application also provides a seat cushion protector box, which includes a box body and the aforementioned seat cushion protector roll. The box body has an accommodating space, within which the seat cushion protector roll is housed. One side wall of the box body has a pull-out opening penetrating the opposite surfaces of the side wall, allowing the seat cushion protector to be pulled out. Furthermore, the seat cushion protector box may also include an elastic fastener, which is fixedly connected to the box body. The elastic fastener has an elastic retaining ring that can engage with the vehicle's longitudinal beam, thereby securing the seat cushion protector box to the vehicle.

[0037] To address the related technical issues, this application also provides a seat cushion protective cover; please refer to [link / reference]. Figures 1 to 3 , Figure 1 This is a schematic diagram of an embodiment of the seat cushion protective cover provided in this application. Figure 2 yes Figure 1 The first embodiment of the seat cover shown is a cross-sectional view along the AA direction. Figure 3 yes Figure 1 The second embodiment of the seat cover shown is a cross-sectional view along the AA direction.

[0038] The seat cover 10 includes a sheet-like main body 100, an easy-tear film 200, and a cover body 300. The sheet-like main body 100 has a clearance opening 110 extending through both opposite sides of the sheet-like main body 100. The easy-tear film 200 is connected to one side of the sheet-like main body 100 and blocks the clearance opening 110. The cover body 300 is connected to the other side of the sheet-like main body 100 and has a fitting cavity. The opening of the fitting cavity corresponds to the clearance opening 110. The easy-tear film 200 is configured to be separate from the sheet-like main body 100 so that the seat cushion can be accommodated in the fitting cavity through the clearance opening 110.

[0039] The sheet-like main body 100 can be in sheet or film form. The sheet-like main body 100 has an abutment 110 that extends through both opposite sides of the sheet-like main body 100. The abutment 110 can be circular, elliptical, or a shape adapted to fit the cushion so that the cushion can pass through it. The sheet-like main body 100 can be square, circular, or elliptical. Multiple sheet-like main bodies 100 are connected sequentially. The two opposite sides of the sheet-like main bodies 100 can be parallel to each other to ensure a suitable connection length between the multiple cushion protective covers 10, reducing the risk of the cushion protective covers 10 easily separating during rolling.

[0040] The easy-tear film 200 can be the same as the sheet-like body 100, or it can be understood as sheet-like or film-like. The outer peripheral shape of the easy-tear film 200 can match the clearance opening 110, and the easy-tear film 200 can be arranged opposite to the clearance opening 110 and connected to one side of the sheet-like body 100 to seal the clearance opening 110. The bag-covering body 300 is connected to the other side of the sheet-like body 100, and the bag-covering body 300 corresponds to the clearance opening 110 and is connected to the sheet-like body 100 on the periphery of the clearance opening 110. The bag-covering body 300 has a bag-covering cavity, which communicates with the outside of the bag-covering body 300 through the clearance opening 110. The easy-tear film 200 seals the clearance opening 110, thereby sealing the bag-covering cavity of the bag-covering body 300, keeping the bag-covering cavity of the bag-covering body 300 isolated from the outside, and reducing the risk of contamination of the bag-covering cavity. A first tear line can be provided at the connection between the easy-tear film 200 and the sheet-like body 100 to facilitate the separation of the easy-tear film 200 from the sheet-like body 100. After separation, the avoidance opening 110 can be exposed, allowing the seat cushion to enter the bag cavity through the avoidance opening 110, thereby reducing the risk of disease transmission from the seat cushion. Of course, the easy-tear film 200 can also cover the avoidance opening 110, that is, the radial dimension of the easy-tear film 200 can be larger than the radial dimension of the avoidance opening 110. The easy-tear film 200 is connected to the side of the sheet-like body 100 away from the bag-like body 300, and a first tear line can be provided at the connection between the two. The first tear line can be formed by laser indentation or hot pressing, which facilitates the separation of the easy-tear film 200 from the sheet-like body 100 and ensures the integrity of the sheet-like body 100.

[0041] In the above-described embodiments, the bag body 300 is connected to one side of the sheet body 100 and is positioned opposite to the clearance opening 110 of the sheet body 100. The easy-tear film 200 is connected to the other side of the sheet body 100 and blocks the clearance opening 110. The bag body 300 has a bag-like structure. After the easy-tear film 200 is separated from the sheet body 100, the seat cushion protective cover 10 can be placed on the seat cushion through the clearance opening 110, thereby reducing the risk of disease transmission.

[0042] Figure 2 This indicates that the seat cover 10 is folded. Figure 3 This indicates that the seat cover 10 is in the unfolded state.

[0043] In some embodiments, the bag body 300 includes a cylindrical connecting portion 310 and a sheet-like fitting portion 320. The sheet-like fitting portion 320 is disposed opposite to the clearance opening 110. One end of the cylindrical connecting portion 310 is connected to the periphery of the sheet-like fitting portion 320, and the other end of the cylindrical connecting portion 310 is correspondingly connected to the clearance opening 110. The cylindrical connecting portion 310 is configured to be foldable or unfoldable. The cylindrical connecting portion 310 may be cylindrical, which can be understood as a cylindrical structure with an internal space formed by connecting the two ends of a sheet-like object. The two ends of the cylindrical structure have openings. The sheet-like fitting portion 320 is connected to one end of the cylindrical connecting portion 310 and seals the opening at one end of the cylindrical connecting portion 310. The sidewall of the cylindrical connecting portion 310 forms a certain angle with the plane of the sheet-like body 100, thereby forming a bag cavity in the bag body 300 for accommodating the cushion. The sheet-like fitting portion 320 can also be arranged opposite to the clearance opening 110, and the opening at the other end of the cylindrical connecting portion 310 is arranged corresponding to the clearance opening 110, and is connected to the sheet-like main body 100 around the clearance opening 110, so as to connect the bag body 300 and the sheet-like main body 100 into one piece. In addition, the cylindrical connecting portion 310 can be folded or unfolded. During the manufacturing process of the cushion protective cover 10, the cylindrical connecting portion 310 is in a folded state, so that the cylindrical connecting portion 310 is folded into a sheet-like structure, so that the entire folded cylindrical connecting portion 310 is close to the sheet-like main body 100, and the sheet-like fitting portion 320 is connected to the cylindrical connecting portion 310, so that the sheet-like fitting portion 320 is also close to the sheet-like main body 100, thereby forming the entire sheet-like structure of the sheet-like main body 100 and the bag body 300, so as to facilitate the rolling up of the cushion protective cover 10. When using the seat cover 10, the tubular connecting part 310 can be unfolded, and the sheet-like fitting part 320 can be moved away from the sheet-like main body 100 to form a pocket cavity.

[0044] In some embodiments, the cylindrical connecting portion 310 is provided with a folding crease 311, which is provided along the wall surface of the cylindrical connecting portion 310 and spaced apart from both ends of the cylindrical connecting portion 310. The cylindrical connecting portion 310 is provided with a folding crease 311, which is located on the wall surface of the cylindrical connecting portion 310 and can be provided circumferentially along the cylindrical connecting portion 310 so that the cylindrical connecting portion 310 can be folded along the folding crease 311. The fold crease 311 can be located between the two ends of the cylindrical connecting portion 310 in the axial direction. That is to say, the fold crease 311 can be parallel and spaced apart from the two ends of the cylindrical connecting portion 310 in the axial direction. Specifically, the fold crease 311 and the two ends of the cylindrical connecting portion 310 are equal. After the cylindrical connecting portion 310 is folded, the sheet-like bonding portion 320 can continue to maintain a relative arrangement with the clearance opening 110. During the rolling process of the seat cushion protective cover 10, the sheet-like bonding portion 320 is opposite to the clearance opening 110, and part of the sheet-like bonding portion 320 and the cylindrical connecting portion 310 are located inside the clearance opening 110, thereby making the seat cushion protective cover 10 flatter and easier to roll.

[0045] See Figure 4 , Figure 4 yes Figure 3 A first-view structural schematic diagram of an embodiment of the sheet-like bonding portion shown.

[0046] In some embodiments, the sheet-like bonding portion 320 includes an antibacterial layer 321 and a barrier layer 322 stacked on top of each other. The antibacterial layer 321 is located on the side closer to the avoidance opening 110, and the barrier layer 322 is located on the side of the antibacterial layer 321 away from the avoidance opening 110. The sheet-like bonding portion 320 includes the stacked antibacterial layer 321 and the barrier layer 322. The antibacterial layer 321 is located on the side of the sheet-like bonding portion 320 closer to the avoidance opening 110, and the barrier layer 322 can be stacked on the side of the antibacterial layer 321 away from the avoidance opening 110. The antibacterial layer 321 can be prepared with polyacrylonitrile as the main material. The antibacterial layer 321 may also include one or two of the following materials: covalently grafted polyhexamethylene biguanide and copper oxide. Both covalently grafted polyhexamethylene biguanide and copper oxide can inhibit microorganisms, thereby killing pathogens and inhibiting the growth of microorganisms, which can further reduce the risk of disease transmission from the cushion. The barrier layer 322 can be made of a thermoplastic polymer material to prevent pathogens such as bacteria or microorganisms from migrating to the user. Furthermore, the sheet-like bonding portion 320 may also include a wear-resistant layer, which can be made of high-molecular-weight polyethylene for increased wear resistance and improved strength of the seat cover 10. Of course, the antibacterial layer 321, the barrier layer 322, and the wear-resistant layer can also be made of the same material, with different functional components added to different functional layers. In addition, different functional layers can be interconnected to reduce the risk of slippage between them. Specifically, different functional layers can be joined together by hot pressing, or multiple fixing points can be formed between different functional layers by hot pressing. The functional layer can refer to any one of the antibacterial layer 321, the barrier layer 322, and the wear-resistant layer, and may also include sheet-like or film-like structures with other functions.

[0047] See Figure 5 , Figure 5 yes Figure 3 A second-view structural schematic diagram of an embodiment of the sheet-like bonding portion shown.

[0048] In some embodiments, the sheet-like bonding portion 320 further includes a weak adhesive layer 323. The weak adhesive layer 323 is located on the side of the antibacterial layer 321 near the clearance opening 110. The area of ​​the weak adhesive layer 323 is smaller than the area of ​​the antibacterial layer 321. The weak adhesive layer 323 is connected to the side of the easy-tear film 200 near the bag body 300. With the weak adhesive layer 323 located on the side of the sheet-like bonding layer near the clearance opening 110, the weak adhesive layer 323 can adhere to the easy-tear film 200. This allows the sheet-like bonding portion 320 to remain close to the clearance opening 110 even when the tubular connecting portion 310 is in a folded state, reducing the risk of slippage. This ensures that the sheet-like bonding portion 320 remains smooth during the rolling process of the seat cushion protective cover 10, making it easier to roll up the seat cushion protective cover 10. Furthermore, the area of ​​the weak adhesive layer 323 is smaller than that of the antibacterial layer 321. This means that the weak adhesive layer 323 does not cover the antibacterial layer 321, thus allowing the weak adhesive layer 323 to exert its adhesive function while also enabling the antibacterial layer 321 to perform its antibacterial function. The weak adhesive layer 323 has low adhesion, ensuring the integrity of the sheet-like adhesive portion 320 during the separation of the easy-tear film 200 from the weak adhesive layer 323.

[0049] In some embodiments, the weak adhesive layer 323 can be separated from the easy-tear film 200, and after separation, it can be attached to the seat cushion. When using the seat cushion cover 10, the easy-tear film 200 must be separated from the sheet-like main body 100 and the sheet-like adhesive portion 320 before the seat cushion cover 10 can be used to accommodate the seat cushion. In addition to being able to adhere to the easy-tear film 200, the weak adhesive layer 323 can also adhere to the seat cushion after the easy-tear film 200 is separated from the sheet-like adhesive portion 320. This reduces slippage between the sheet-like adhesive portion 320 and the seat cushion during use, improving the user experience and enhancing safety.

[0050] In addition, in some embodiments, the seat cover 10 also includes an anti-spreading film 400, which is connected to the side of the sheet body 100 near the bag body 300. The anti-spreading film 400 and the sheet body 100 form a receiving cavity for accommodating the folded bag body 300. The anti-spreading film 400 is configured to be separate from the sheet body 100. The anti-spreading film 400 is connected to the side of the sheet-like body 100 near the bag body 300, and the radial dimension of the anti-spreading film 400 can be larger than the radial dimension of the clearance hole, so that the anti-spreading film 400 and the sheet-like body 100 form a receiving cavity and completely cover the bag body 300. When the bag body 300 is in a folded state, the anti-spreading film 400 is connected to the sheet-like body 100, and the bag body 300 is housed in the receiving cavity, thereby allowing the anti-spreading film 400 to cover the bag body 300, reducing the risk of the tubular connecting part 310 of the bag body 300 being unfolded by external force, making the corresponding side of the seat cushion protective cover 10 flatter, and making it easier to roll up the seat cushion protective cover 10. When the seat cover 10 is put on the seat cushion, the anti-spreading film 400 can be separated from the sheet body 100. Specifically, a second tear line can be provided at the connection between the anti-spreading film 400 and the sheet body 100 so that the anti-spreading film 400 can be separated more easily and the integrity of the sheet body 100 can be guaranteed.

[0051] In some embodiments, the barrier layer 322 is provided with anti-slip textures 324. When the outermost layer of the sheet-like adhesive portion 320 away from the clearance opening 110 is the barrier layer 322, the barrier layer 322 may be provided with anti-slip textures 324, thereby reducing the risk of the user slipping while riding. Of course, when the outermost layer of the sheet-like adhesive portion 320 away from the clearance opening 110 is a wear-resistant layer, the wear-resistant layer may be provided with anti-slip textures 324. That is to say, it is sufficient to provide anti-slip textures 324 on the outermost layer of the sheet-like adhesive portion 320 away from the clearance opening 110 to increase the coefficient of friction of the sheet-like adhesive portion 320. In other embodiments, the sheet-like bonding portion 320 may include multiple functional layers, which can be interconnected. The entire multi-functional layer may be provided with anti-slip texture 324. In other words, the multiple functional layers of the sheet-like bonding portion 320 are a single unit. When setting the anti-slip texture 324, the entire sheet-like bonding portion 320 can be provided with the anti-slip texture 324 by hot pressing, and it is not limited to setting the anti-slip texture 324 only on one functional layer. The anti-slip texture 324 can take many forms. As one example, the anti-slip texture 324 may include multiple dotted protrusions evenly distributed within the sheet-like bonding portion 320. As another example, the anti-slip texture 324 may include multiple intersecting stripes, which can be evenly arranged or have different spacing densities as needed. The specific shape of the anti-slip texture 324 can be adjusted according to actual conditions, and this application does not limit it here.

[0052] In some embodiments, the seat cover 10 may further include an annular contraction portion, which can be regarded as a ring-shaped sheet structure. The annular contraction portion is disposed at a position corresponding to the clearance opening 110. The outer periphery of the annular contraction portion is connected to the periphery of the clearance opening 110 of the sheet body 100. An elastic cord may be embedded in the inner periphery of the annular contraction portion. The elastic cord can be stretched and retracted. The elastic cord can switch between a shortened state and an extended state. When the elastic cord switches from a shortened state to an extended state, the radial dimension of the inner periphery of the annular contraction portion can increase from small to large. In other words, when the elastic cord is in a shortened state, the elastic cord causes the inner circumference of the annular contraction part to contract and fold, thereby reducing the radial dimension of the inner circumference of the annular contraction part and placing it within the clearance opening 110. When the elastic cord is in a stretched state, the elastic cord causes the inner circumference of the annular contraction part to unfold, thereby increasing the radial dimension of the inner circumference of the annular contraction part. As a result, when the main body of the cover 300 is fitted onto the cushion, the cushion protective cover 10 can be fixed to the cushion through the annular contraction part, improving the convenience of the cushion protective cover 10 and reducing the risk of the cushion protective cover 10 detaching from the cushion.

[0053] Of course, in other embodiments, an adhesive portion may be provided on the side of the sheet-like main body 100 away from the cover body 300. When the cover body 300 is fitted onto the seat cushion, the sheet-like main body 100 can be glued to the bottom of the seat cushion through the adhesive portion, thereby reducing the risk of the seat cushion cover 10 detaching from the seat cushion.

[0054] In summary, the bag body 300 is connected to one side of the sheet body 100 and is positioned opposite to the clearance opening 110 of the sheet body 100. The easy-tear film 200 is connected to the other side of the sheet body 100 and blocks the clearance opening 110. The bag body 300 has a bag-like structure. After the easy-tear film 200 is separated from the sheet body 100, the seat cushion protective cover 10 can be placed on the seat cushion through the clearance opening 110, thereby reducing the risk of disease transmission.
