Description

Technical Field

[0001] This utility model belongs to the technical field of transportation tools, specifically relating to a seat cushion and an electric vehicle. Background Technology

[0002] With the continuous development of technology, the types of transportation tools are gradually increasing. Various simple and easy-to-drive electric vehicles are gradually entering daily life. Due to their ease of use and lightweight convenience, electric vehicles are favored by many users. As electric vehicles develop, user demands are also increasing, requiring more space in the seat compartment. While widening and enlarging the seat compartment, the seat cushion also needs to be adjusted accordingly. During this adjustment process, while considering the aesthetics of the electric vehicle, a high level of comfort is required during use. However, current technologies only focus on supporting the driver's buttocks, while leg comfort needs improvement.

[0003] In other words, existing wide-body seat cushions suffer from low seating comfort. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is how to improve the comfort of wide-body seat cushions.

[0005] To solve the above-mentioned technical problems, the present invention provides a seat cushion, including: a seat portion; at least two leg support portions, the at least two leg support portions being disposed on both sides of the seat portion in the width direction, and the lowest point of the seat portion and the widest position of the seat cushion being spaced apart in the length direction of the seat cushion.

[0006] Optionally, the widest part of the seat cushion is located in the front half of the seat cushion along its length. This design allows the leg rest to conform more naturally to the legs, increasing the leg support area and improving comfort and safety during driving.

[0007] Optionally, the lowest point of the seat is located in the rear half of the seat cushion along its length. This ensures sufficient support area for the driver and guarantees driver comfort.

[0008] Optionally, the ratio of the sum of the widths of the two leg rests at their widest positions on the seat to the widest distance L of the seat is greater than 0.5. This configuration ensures that the leg rests provide sufficient support area, thus providing more comprehensive leg support.

[0009] Optionally, the proportion of the leg rest in the width direction of the seat cushion gradually increases from the widest point of the seat cushion towards the front. This gradual support design can more subtly match the needs of the human body when changing sitting postures.

[0010] Optionally, the ratio of the width of the leg rest at the narrowest point of the seat to the width of the narrowest point of the seat is greater than or equal to 0.8 and less than or equal to 1.2. The width of the leg rest at this point is not too wide, avoiding unnecessary support or pressure on the legs at the narrowest point of the seat cushion.

[0011] Optionally, the seating area includes a driver's seat sub-section and a passenger seat sub-section arranged sequentially along the length of the seat cushion. At least two leg rests are provided on both sides of the driver's seat sub-section. The driver's seat sub-section includes a first seat surface and a second seat surface connected sequentially. The junction of the first seat surface and the second seat surface is the lowest point of the seating area. The width of the first seat surface gradually decreases in the direction away from the passenger seat sub-section. This design ensures that the driver's buttocks and thighs receive proper support when operating the vehicle.

[0012] Optionally, the leg rest includes a support surface that extends obliquely from the first seating surface in a direction away from the second seating surface, with a portion of the support surface closer to the front relative to the first seating surface. This design allows for a more natural fit to the leg curve, providing a comfortable support angle and reducing leg discomfort during prolonged sitting.

[0013] Optionally, the leg rest and seat area can be a single piece of sealed fabric. This design reduces gaps or seams between different parts, making the overall seat smoother and reducing potential pressure marks or discomfort caused by seams, thus improving the user's comfort experience.

[0014] This utility model also provides an electric vehicle, including the aforementioned seat cushion.

[0015] The technical solution provided by this utility model has the following advantages:

[0016] The seat cushion provided by this utility model includes a seat portion and at least two leg support portions. The at least two leg support portions are arranged on both sides of the seat portion in the width direction, and the lowest point of the seat portion and the widest position of the seat cushion are spaced apart in the length direction of the seat cushion.

[0017] The seat section supports the driver's buttocks, while the leg rest supports the driver's thighs. This provides effective support for both the buttocks and thighs, making the seat more ergonomic and significantly improving driver comfort. It allows for a more natural driving posture and reduces fatigue during long drives. The spacing between the lowest point of the seat section and the widest point of the seat along its length increases design flexibility, allowing for better design of the leg rest and further enhancing comfort. This ensures optimized legroom for the driver while providing sufficient soft support, enhancing the overall riding experience. Attached Figure Description

Detailed Implementation

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0034] In order to solve the problem of low seating comfort in existing seat cushions, this utility model provides a seat cushion and an electric vehicle.

[0035] like Figures 1 to 10 As shown, the seat cushion includes a seat portion 10 and at least two leg support portions 20. The at least two leg support portions 20 are disposed on both sides of the seat portion 10 in the width direction, and the lowest point of the seat portion 10 and the widest position of the seat cushion are spaced apart in the length direction of the seat cushion.

[0036] The seat 10 supports the driver's buttocks, while the leg rest 20 supports the driver's thighs. This provides effective support for both the driver's buttocks and thighs, making the seat more ergonomic and improving driver comfort. This allows for a more natural driving posture and reduces fatigue during long drives. The spacing between the lowest point of the seat 10 and the widest point of the seat along its length increases design flexibility, allowing for better design of the leg rest 20 and further enhancing comfort. This optimizes legroom for the driver while providing sufficient soft support, enhancing the overall riding experience.

[0037] exist Figure 2 In the embodiment shown, the widest position of the seat cushion is the position of line B, the lowest point of the seat portion 10 is the position of line C, the position of half the maximum length of the seat cushion is the position A, the front side of the position A is the front half area of ​​the seat cushion along the length direction, and the rear side of the position A is the rear half area of ​​the seat cushion along the length direction.

[0038] In some alternative embodiments, please refer to Figure 2 The widest part of the seat cushion is located in the front half of its length. This design allows the leg rest 20 to conform more naturally to the legs, especially when the driver needs more legroom. It follows ergonomic principles, emphasizing that the legs naturally extend forward in a relaxed state. Therefore, placing the widest part of the seat cushion at the front better accommodates this natural posture, providing the driver with more legroom, reducing leg pressure, and improving comfort and safety during driving. Positioning the widest part in the front half of the seat cushion's length also makes more efficient use of the space at the front of the vehicle. This maximizes comfort without compromising driver operability and safety.

[0039] In some alternative embodiments, please refer to Figure 2 The lowest point of the seat 10 is located in the rear half of the seat cushion along its length. By placing the lowest point of the seat 10 behind the midpoint of the seat cushion's length, the area of ​​support provided by the seat 10 to the driver is ensured, guaranteeing the driver's seating comfort. This arrangement ensures a more stable driving posture and reduces body swaying during driving. It utilizes the natural distribution of the human body's center of gravity, placing the lowest point of the seat cushion at the rear, which helps maintain body balance and reduces discomfort during driving. This design improves driver comfort, especially during long drives, effectively relieving pressure on the hips and lower back.

[0040] This design follows the natural curves of the human body when sitting, especially taking into account the S-curve of the spine. Positioning the lowest point of the seat cushion at the rear allows the buttocks to naturally sink to a position that better conforms to the physiological curvature of the spine when seated, helping to maintain correct posture and reducing back fatigue and discomfort caused by prolonged sitting. As the primary support point for the body when seated, placing the buttocks in the more stable and firm rear area of ​​the cushion provides stronger support, making the person sitting on the cushion feel more secure. At the same time, the slightly increased height of the front of the cushion provides gentle support for the thighs, avoiding direct pressure on the blood vessels and nerves behind the knees, thus improving comfort during long periods of sitting.

[0041] In addition, the slightly higher front end of the seat cushion helps promote blood circulation in the lower limbs and reduces the risk of varicose veins. Along the length of the seat cushion, the lowest point of the sitting area is positioned rearward, ensuring a slight upward tilt of the legs. This posture reduces resistance to blood return from the lower limbs, promoting blood circulation.

[0042] In some alternative embodiments, the ratio of the sum of the widths of the two leg rests 20 at their widest positions on the seat cushion to the widest distance L of the seat cushion is greater than 0.5. This arrangement ensures that the leg rests 20 provide sufficient support area, thereby providing more comprehensive leg support. This design ensures that the thighs are adequately supported when the user sits down, reducing leg muscle tension, and significantly improving comfort, especially when driving or sitting for long periods.

[0043] Because the ratio of the leg rest width to the widest part of the seat cushion is greater than 0.5, the area around the legs is not too narrow, avoiding a feeling of "legs being squeezed." Users can freely adjust their sitting posture without worrying about excessive pressure on the legs from both sides, which is crucial for improving comfort during long journeys.

[0044] Providing ample leg support at the widest point of the seat cushion is ergonomically designed, as this is where the thighs naturally rest when the user sits. This design better adapts to the natural sitting posture, reducing discomfort and effectively improving the seat cushion's comfort.

[0045] exist Figure 6 In the specific embodiment shown, the length of one leg support 20 at the widest position of the sensing cushion is T1, and the length of the other leg support 20 at the widest position of the sensing cushion is T2, that is, (T1+T2) / L is greater than 0.5.

[0046] In some alternative embodiments, please refer to Figure 2The leg support 20 gradually increases in width from the widest point of the seat towards the front. This design allows the leg support 20 to provide strong support for the driver's legs while preventing the driver's legs from getting stuck in the seat width, effectively improving seat comfort. From the rear to the front of the seat, the leg support area gradually expands; this gradual support design more subtly matches the needs of changing sitting postures. After providing initial leg support at the widest point, the forward area offers a wider support area, helping to evenly distribute leg pressure, reduce localized pressure pain, and provide continuous and comfortable support.

[0047] By gradually increasing the width of the leg support at the front of the seat cushion, the designers considered the natural tendency of the legs to extend forward when sitting. This avoids the legs encountering narrow or hard edges suddenly when moving forward, allowing the user's legs to relax naturally and reducing muscle tension and fatigue. This design better meets the needs of users with different body types or sitting posture preferences. Whether the user is in a standard sitting posture or prefers to spread their legs slightly, the seat cushion provides just the right amount of support, adapting to various sitting positions and improving the comfort and applicability of the seat cushion.

[0048] Furthermore, the gradually increasing width of the leg rests prevents excessive compression of the legs in the lateral direction, especially when maintaining a seated posture for extended periods. Users can freely adjust the position of their legs, experiencing the cushion's support and comfort whether making slight lateral movements or crossing their legs.

[0049] In some alternative embodiments, the ratio of the width of the leg rest 20 at the narrowest point of the seat 10 to the width of the narrowest point of the seat 10 is greater than or equal to 0.8 and less than or equal to 1.2. This ratio, between 0.8 and 1.2, means that the leg rest is not excessively wide at this point, avoiding unnecessary support or pressure on the legs at the narrowest part of the seat cushion. This precise width adjustment ensures that the leg rest fits the thigh perfectly, providing the necessary support without compromising the comfort of other parts of the body.

[0050] In seat cushion design, different parts of the human body have different support needs. The width design of the leg rest takes into account the natural position and width of the thighs when sitting, as well as their relative position to the buttocks. By limiting the width ratio, it is possible to ensure that the leg rest works in coordination with other parts of the seat cushion, which conforms to ergonomic principles, allowing the seat cushion to better adapt to the curves of the human body and reduce pressure points and discomfort that may occur during long periods of sitting.

[0051] exist Figure 5In the specific embodiment shown, the width of the leg support 20 at the narrowest position of the seat 10 is S2, and the width of the narrowest position of the seat 10 is S1.

[0052] In some alternative embodiments, please refer to Figure 2 The seating section 10 includes a driver's seat sub-section 11 and a passenger seat sub-section 12 arranged sequentially along the length of the seat cushion. At least two leg rests 20 are provided on both sides of the driver's seat sub-section 11. The driver's seat sub-section 11 includes a first seat surface 111 and a second seat surface 112 connected sequentially. The connection point of the first seat surface 111 and the second seat surface 112 is the lowest point of the seating section 10. The width of the first seat surface 111 gradually decreases in the direction away from the passenger seat sub-section 12. The structural design of the driver's seat sub-section 11, especially with the connection point of the first seat surface 111 and the second seat surface 112 as the lowest point, better adapts to the driver's sitting posture. This design ensures that the driver's buttocks and thighs receive proper support when operating the vehicle, which helps to improve driving comfort and control. The two leg rests 20 are respectively provided on both sides of the driver's seat sub-section 11, which can provide sufficient leg support for the driver and reduce fatigue during long-term driving. Meanwhile, the gradually decreasing width of the first seating surface 111 avoids excessive lateral restriction on the driver's legs, retaining a certain degree of freedom and making it easy to adjust the leg position.

[0053] In some alternative embodiments, please refer to Figure 3 The leg rest 20 includes a support surface 21, which extends obliquely from the first seating surface 111 in a direction away from the second seating surface 112, with a portion of the support surface 21 closer to the front relative to the first seating surface 111. The oblique extension design of the support surface 21 follows the natural downward tilt of the legs when the human body is in a natural sitting posture. This design more naturally conforms to the leg curve, providing a comfortable support angle and reducing leg discomfort during prolonged sitting. The fact that a portion of the support surface 21 is closer to the front means that it provides longer support for the legs, effectively increasing the support area and further enhancing leg stability. The structural design of the support surface 21 avoids direct, rigid support for the legs, instead providing a softer support through oblique extension. This reduces pressure on the legs, especially near the knees, preventing undue interference with blood circulation and improving comfort during long periods of sitting.

[0054] In some alternative embodiments, the supporting surface 21 is an arc-shaped surface, and is a concave arc surface.

[0055] In some alternative embodiments, the angle between the support surface 21 and the vertical direction gradually increases from front to back, so as to more naturally conform to the curve of the leg, provide a comfortable support angle, and reduce leg discomfort when sitting for a long time.

[0056] In some alternative embodiments, the leg rest 20 and the seat 10 are a single, integrated fabric structure. This integrated structure means that the leg rest 20 and the seat 10 share the same layer of fabric. This design reduces gaps or seams between different parts, making the overall seat cushion smoother and reducing potential pressure marks or discomfort caused by seams, thus improving user comfort. The continuity of the fabric also allows the seat cushion to better conform to the body's curves; both the seat 10 and the leg rest 20 can better adapt to the user's body shape, providing seamless support.

[0057] By reducing the number of seams in the cover, the risk of damage caused by seam wear and tear is reduced, thus improving the durability of the seat cushion. The one-piece cover design reduces wear points and enhances the cushion's durability. At the same time, improved water resistance and a simplified cleaning process make it easier for drivers or vehicle owners to maintain the cleanliness of the seat cushion and extend its lifespan.

[0058] In some alternative embodiments, please refer to Figure 2 and Figure 3 The seat cushion also includes a front portion 110 and a side portion 120. The front portion 110 is at least located on the front side of the seat portion 10 and is connected to the seat portion 10 and the two leg rest portions 20. The side portion 120 is located on opposite sides of the seat portion 10 and is located on the rear side of the leg rest portions 20. The side portion 120 is connected to both the leg rest portions 20 and the seat portion 10.

[0059] Optionally, the front part 110, the seat part 10, and the leg rest part 20 are separate cover structures.

[0060] Optionally, the side portion 120, the seat portion 10, and the leg rest portion 20 are separate cover structures.

[0061] Optionally, the seat cushion is a sensor-activated seat cushion.

[0062] In some alternative embodiments, please refer to Figure 1 and Figure 7 The seat cushion includes a seat cushion body 100, a seat cushion base plate 30, and a sensor assembly 40. The seat cushion base plate 30 is located on one side of the seat cushion body 100 and has a mounting through hole 31. The sensor assembly 40 is disposed in the mounting through hole 31, and one side surface of the sensor assembly 40 is exposed on the side of the seat cushion base plate 30 facing the seat cushion body 100, while the other side surface of the sensor assembly 40 is exposed on the side of the seat cushion base plate 30 away from the seat cushion body 100.

[0063] The driver sits on the seat cushion body 100, and the seat cushion base plate 30 supports the seat cushion body 100 to ensure the seat cushion supports the driver and passenger. A sensor assembly 40 is installed on the seat cushion base plate 30. The pressure detected by the sensor assembly 40 determines whether the driver is seated in the driver's seat, effectively reducing the risk of the electric vehicle lurching forward due to accidental contact by the driver or others when the driver is not in the driver's seat, thus reducing safety hazards and improving the safety of electric vehicle use. Exposing one side of the sensor assembly 40 to the side of the seat cushion base plate 30 facing the seat cushion body 100 ensures a proper distance between the sensor assembly 40 and the seat cushion body 100, thereby improving the detection accuracy of the sensor assembly 40 and preventing situations where the sensor assembly 40 fails to detect the driver sitting in the driver's seat.

[0064] Furthermore, the sensor assembly 40 is partially exposed on both sides of the seat cushion base plate 30, which reduces its demand on the internal space of the seat cushion and leaves more room for other important components (such as cushioning components, reinforcing ribs, etc.), contributing to the compactness and lightweight of the overall design. At the same time, one side of the sensor assembly 40 faces the seat cushion body 100, which can sense the pressure applied by the driver, while the other side faces the back of the seat cushion base plate 30. In this way, even when the seat cushion body 100 is not in direct contact with the seat cushion base plate 30 (such as when the seat cushion is raised or slightly displaced), the sensor can still detect changes on the seat cushion base plate 30, thereby providing more comprehensive sensing information.

[0065] By placing the sensor assembly 40 within the mounting through hole 31 of the seat base plate 30 and using the seat base plate 30 as a support structure, the positional shift or damage of the sensor assembly 40 due to vibration or impact during long-term use can be effectively prevented, thereby improving the stability and reliability of the entire sensing system.

[0066] Furthermore, installing the sensor assembly 40 within the mounting through-hole 31 means that the sensor can be replaced or upgraded relatively independently of the seat cushion body without disassembling the entire seat cushion, reducing maintenance costs and time consumption, while also facilitating subsequent functional expansion and technology updates.

[0067] It should be noted that the seat body 100 includes the aforementioned front part 110, seat part 10, leg support part 20, and side part 120.

[0068] In some alternative embodiments, please refer to Figures 8 to 10The sensor cushion also includes multiple fasteners 50. The cushion base plate 30 has multiple mounting holes, and the sensor assembly 40 has multiple mating holes that mate with the mounting holes. At least two mating holes are located on opposite sides of the cushion base plate 30, and the fasteners 50 pass through the mating holes and mounting holes. By setting two different mating holes on opposite sides of the cushion base plate 30, a portion of the sensor assembly 40 is fixed to one side surface of the cushion base plate 30, and the other portion is fixed to the other side surface of the cushion base plate 30. This arrangement facilitates the stable fixation of the sensor assembly 40 to the cushion base plate 30. The fasteners 50 pass through the corresponding mating holes on the sensor assembly 40 and connect with the mounting holes, forming a multi-point fixing structure. This design effectively distributes the force borne by the sensor assembly 40, avoids force concentration at a single fastening point, and greatly reduces bolt loosening caused by vibration or impact, thereby ensuring the stable operation of the sensor assembly 40 under various working conditions.

[0069] Multiple mounting holes are provided around the mounting through hole 31, and at least one mounting hole is located on one side of the wide side of the mounting through hole 31, and at least another mounting hole is located on one side of the long side of the mounting through hole 31.

[0070] The plurality of mounting holes include at least one first mounting hole 391 and a plurality of second mounting holes 392, wherein the first mounting hole 391 and the second mounting hole 392 are respectively formed on the surface of different sides of the seat base plate 30.

[0071] The plurality of mating holes include at least one first mating hole 41 and a plurality of second mating holes 42, wherein the first mating hole 41 corresponds to the first mounting hole 391, and the second mating holes 42 mate with the second mounting holes 392.

[0072] In some alternative embodiments, a plurality of second mounting holes 392 are respectively provided on opposite sides of the assembly through hole 31, and the second mounting holes 392 on the same side are spaced apart along the length direction of the assembly through hole 31 to form a multi-point fixing structure.

[0073] In some alternative embodiments, the first mounting hole 391 is located on one side of the wide side of the mounting through hole 31.

[0074] Furthermore, the precise fit between the fasteners 50 and the mating holes and mounting holes ensures accurate alignment of the sensor assembly 40 during installation, preventing installation deviations. Each combination of fastener 50 with the mating holes and mounting holes guarantees both the stability of the sensor assembly 40 and provides flexibility. When it is necessary to adjust the sensor position or replace the sensor, only the corresponding fastener 50 needs to be loosened, without having to remove the entire seat base plate. This design simplifies the maintenance process and saves time and costs.

[0075] In some alternative embodiments, please refer to Figure 9 and Figure 10 The multiple second mounting holes 392 symmetrically arranged on both sides of the mounting through hole 31 and the multiple second mating holes 42 on the sensor assembly 40 ensure symmetrical installation of the sensor assembly. This not only helps to evenly distribute the load on the seat base plate 30, but also avoids stress imbalance that may be caused by asymmetrical installation, thus extending the overall service life of the seat.

[0076] It should be noted that the number and position of multiple fasteners 50 can be flexibly adjusted according to specific usage requirements. For example, fastening points can be added in certain high-pressure areas or areas with large movements to cope with different pressure loads and ensure the accuracy and durability of the seat cushion in various application scenarios.

[0077] Alternatively, fastener 50 can be a screw.

[0078] In some alternative embodiments, please refer to Figure 7 The seat base plate 30 includes a driver's seating area 32, and a mounting through hole 31 is located within the driver's seating area 32. The driver's seating area 32 is the area on the seat that experiences the greatest and most frequent pressure. By placing the mounting through hole 31 within the driver's seating area 32, the sensor assembly 40 can be mounted within the driver's seating area 32, ensuring that the sensor assembly 40 detects pressure changes at the driver's seating area 32. This improves detection accuracy and ensures that power is only supplied when a driver is seated in the driver's seating area 32, reducing potential safety hazards.

[0079] In some alternative embodiments, the ratio of the length of the sensor assembly 40 along the length of the seat cushion to the maximum length of the driver's seating area 32 along the length of the seat cushion is greater than or equal to 2 / 3. This arrangement ensures that the sensor assembly 40 has a certain detection range, guaranteeing that it can accurately and quickly detect pressure changes after the driver sits on the seat cushion, preventing situations where the sensor assembly 40 cannot detect changes after the driver sits on the seat cushion, thus ensuring the detection accuracy of the sensor assembly 40. The wide coverage of the sensor assembly 40 helps to detect abnormal driver behavior in a timely manner, such as suddenly leaving the seat or unstable posture, which is of great value in enhancing vehicle safety.

[0080] In some alternative embodiments, please refer to Figure 7 and Figure 8The seat cushion base plate 30 has a raised portion 33 that bulges towards the side where the seat cushion body 100 is located. The raised portion 33 has a driver seating area 32 and a passenger seating area 34 arranged sequentially along the length of the seat cushion. By providing the raised portion 33 on the seat cushion base plate 30, the raised portion 33 increases the structural complexity of the seat cushion base plate 30. This structural change helps to improve the overall rigidity and strength of the base plate. During vehicle operation, the seat cushion base plate 30 may be subjected to forces from different directions. The design of the raised portion 33 can enhance the bending and compressive strength of the seat cushion base plate 30 without significantly increasing the amount of material used, ensuring that the seat cushion can reliably support the driver and passenger.

[0081] Furthermore, the design of the raised portion 33 helps to evenly distribute the pressure applied to the seat cushion. Especially in the driver's seating area 32 and the passenger seating area 34, the raised portion increases the contact area between the seat cushion body 100 and the seat cushion base plate 30, thereby reducing pressure concentration, improving seating comfort, and reducing localized wear between the seat cushion body 100 and the seat cushion base plate 30. The raised portion 33 design in the driver's seating area 32 and the passenger seating area 34 provides more ergonomic seating support. By adjusting the shape and height of the raised portion, it can better adapt to the body contours of different users, reducing discomfort caused by long-term driving or sitting.

[0082] Meanwhile, the arrangement of the raised sections 33 takes into account the internal space planning of the seat cushion. In some designs, the space below the raised sections can be used to arrange other components, such as sensor assembly 40, cushioning components, reinforcing ribs, etc., achieving efficient use of space and also providing clearance for possible accessories.

[0083] In addition, the raised portion 33 has a driver's seat area 32, and the sensor assembly 40 is disposed on the driver's seat area 32, which can effectively reduce the distance between the sensor assembly 40 and the seat body 100, ensure the detection sensitivity of the sensor assembly 40, and reduce the occurrence of situations where the sensor assembly 40 cannot detect.

[0084] It should be noted that the fact that the sensor assembly 40 cannot detect pressure changes as described in this application does not mean that the sensor assembly 40 cannot detect pressure changes, but rather that the pressure changes detected by the sensor assembly 40 are insufficient to turn on the power of the electric vehicle.

[0085] In some alternative embodiments, please refer to Figure 7 and Figure 8The raised portion 33 includes a first plate segment 35, a second plate segment 36, and a third plate segment 37 connected sequentially along its length. The first plate segment 35 and the second plate segment 36 are located in the driver's seating area 32, and the third plate segment 37 is located in the passenger seating area 34. The third plate segment 37 is located on the side of the first plate segment 35 facing the seat cushion body 100. The first plate segment 35 and the second plate segment 36 are connected in an arc shape, and the second plate segment 36 and the third plate segment 37 are also connected in an arc shape. A mounting through hole 31 is provided in the first plate segment 35. The first plate segment 35 and the third plate segment 37 are located at different heights, which on the one hand helps to improve the structural strength of the seat cushion base plate 30, and on the other hand allows the driver and passenger to sit on different planes, which can reduce the pressure of the passenger on the sensor assembly 40, reduce the impact of the passenger's weight on the detection of the sensor assembly 40, and ensure the detection accuracy of the sensor assembly 40.

[0086] Furthermore, the first segment 35 is located directly in the driver's seating area 32, and the mounting through-hole 31 is located in this segment, ensuring that the sensor assembly 40 can be accurately installed in the seat cushion area most frequently contacted by the driver. This positioning method helps detect whether someone is sitting in the driver's seating area 32. The arcuate connection between the first segment 35 and the second segment 36, as well as the arcuate connection between the second segment 36 and the third segment 37, forms a smoothly transitioning curved surface. This design can effectively distribute the pressure applied to the seat cushion, avoiding the formation of pressure concentration points, thereby improving riding comfort and seat cushion durability. The segmented design of the raised portion 33, especially the arcuate connection between each segment, increases the structural strength and stability of the seat cushion base plate 30. This design can better resist the impacts and vibrations encountered during vehicle operation, ensuring that the seat cushion base plate 30 is not easily deformed or damaged, protecting critical components such as the internal sensor assembly 40. The segmented design of the raised portion 33 also takes into account the layout of internal components of the seat cushion. For example, the mounting through hole 31 under the first plate segment 35 can be used to precisely install the sensor, while other plate segments can be used to arrange buffers, reinforcing ribs, etc., which realizes the effective use of space and avoids mutual interference between components.

[0087] In some alternative embodiments, the driver's seating area 32 has a first plate segment 35 and a second plate segment 36, and the first plate segment 35 is an inclined surface with a higher front end and a lower rear end, which conforms to ergonomics, ensures that the first plate segment 35 is evenly stressed, and at the same time helps to improve the comfort of the driver's seating.

[0088] In some alternative embodiments, please refer to Figure 8 and Figure 9The seat cushion also includes multiple cushioning elements 60. The third plate segment 37 has at least two mounting posts 371 on its surface opposite to the seat cushion body 100. Each mounting post 371 has a mounting groove 372. The cushioning elements 60 are detachably disposed within the mounting groove 372, and at least partially located outside the mounting groove 372. Because the third plate segment 37 is relatively high, by providing cushioning elements 60 on one side of the third plate segment 37, significant displacement at the third plate segment 37 can be avoided after a passenger sits on the seat cushion, preventing the seat cushion from experiencing excessive stress. This not only helps ensure the lifespan of the seat cushion but also improves the passenger's comfort.

[0089] Furthermore, the mounting post 371 and its mounting groove 372 provide a stable mounting base for the buffer 60. By snapping the buffer 60 into the mounting groove 372, the stability and resistance to displacement of the buffer during vehicle operation are ensured, maintaining good performance even under severe vibration or impact. The buffer 60 is positioned via the mounting groove 372 of the mounting post 371, a design that allows for precise placement of the buffer on the third plate segment 37 without occupying additional space. Simultaneously, the removable nature of the buffer 60 simplifies the layout and installation of other components within the seat cushion, improving space utilization and the overall structural compactness. The detachable connection design between the buffer 60 and the mounting groove 372 makes replacement and maintenance of the buffer very convenient. When the buffer 60 ages or becomes damaged, it can be easily removed and replaced with a new one without disassembling the entire seat cushion, reducing maintenance costs and time. The removability and adjustability of the buffer 60 allow it to adapt to different usage scenarios and needs.

[0090] Optionally, the mounting post 371 can accommodate at least two different sizes of cushioning elements 60. By designing the compatibility of different sizes of cushioning elements 60, the appropriate cushioning element 60 can be selected based on the availability of internal space in the seat cushion. For example, a thinner cushioning element can be used when space is limited, while a thicker cushioning element can be selected when there is more space. This flexibility helps to optimize the internal structural configuration of the seat cushion, ensuring that comfort requirements are met without sacrificing installation space for other components.

[0091] It should be noted that different specifications can refer to different lengths, shapes, or sizes; there are no specific restrictions here, as long as the mounting post can accommodate at least two slightly different cushioning components 60, enhancing the versatility of the seat base plate 30. For example, there can be two different sizes of cushioning components 60, or two different lengths of cushioning components 60. There can also be two different shapes of cushioning components 60, such as one cylindrical and one spiral. There are no specific restrictions here.

[0092] In some alternative embodiments, please refer to Figure 8 and Figure 9 The seat base plate 30 has a guide rib 38 extending away from the seat body 100 on the side opposite to the seat body 100. The guide rib 38 is located on the raised side wall of the raised portion 33, and the height of the guide rib 38 gradually decreases towards the third plate segment 37. The guide rib 38 is completely located on the side of the outer periphery of the seat base plate 30 facing the seat body 100. By providing the guide rib 38 on one side of the seat base plate 30, the matching between the seat cushion and the seat bucket can be ensured while avoiding affecting the installation space of accessories. The guide rib 38 is located on the side wall of the raised portion 33, increasing the structural rigidity of the seat base plate 30. This reinforcement is particularly important for distributing loads and resisting deformation, especially under various impacts and vibrations encountered during vehicle operation, effectively ensuring the stability and durability of the base plate. The height of the guide rib 38 gradually decreases towards the third plate segment 37. This design can provide guidance and auxiliary positioning for the installation of other key components on the seat base plate 30 (such as sensor assembly 40, buffer 60, etc.), while ensuring that even if these components are installed, they will not hinder the normal function of the seat base plate 30, such as avoiding the protrusion of the buffer 60 from affecting the installation of accessories.

[0093] Furthermore, the height of the guide rib 38 gradually decreases, and it is entirely located on the side of the seat cushion body 100 facing the outer periphery of the seat cushion base plate 30. This arrangement prevents the guide rib 38 from protruding and affecting the assembly of the seat cushion base plate 30, as well as from interfering with the assembly of the seat cushion base plate 30 and the seat bucket. The guide rib 38 with its gradually changing height serves as a reference, helping to position other components more quickly and accurately during installation, avoiding functional problems or structural instability caused by misalignment or installation deviations. The design of the guide rib 38 takes into account compatibility with other components, especially its height variation and position selection, ensuring sufficient space for the arrangement of other components while avoiding intrusion into the functional areas of the seat cushion body 100, thus achieving effective management and utilization of internal space.

[0094] In some alternative embodiments, please refer to Figure 8 and Figure 9The seat cushion also includes a sealing strip 70, which is located on the side of the seat cushion base plate 30 opposite to the seat cushion body 100 and surrounds the raised portion 33. The sealing strip 70 seals the gap between the seat cushion and the seat bucket, ensuring the seat bucket's airtightness and reducing the risk of rainwater entering the seat bucket. The sealing strip 70 surrounding the raised portion 33 forms a closed protective barrier, effectively preventing external moisture and dust from entering the seat cushion. This is crucial for protecting internal electronic and mechanical components such as the sensor assembly 40 and the cushioning element 60 from environmental factors, helping to extend the overall lifespan of the seat cushion and maintain its functional reliability. The surrounding arrangement of the sealing strip 70 not only provides waterproof and dustproof functionality but also, through the properties of its elastic material, enhances the tightness of the connection between the raised portion 33 and the seat cushion base plate 30, improving the overall structural strength of the base plate. This reinforcement is particularly significant during vehicle operation, resisting deformation or loosening caused by vibration and impact.

[0095] Furthermore, the elastic material of the sealing strip 70 can absorb and isolate external noise, especially when the vehicle is traveling at high speeds, effectively reducing the transmission of wind and road noise and providing passengers with a quieter riding environment. This is crucial for improving riding comfort and user experience.

[0096] In some alternative embodiments, please refer to Figure 7 The seat cushion base plate 30 has a first reinforcing structure 80 and a second reinforcing structure 90 on the side facing the seat cushion body 100. One of the first reinforcing structures 80 and 90 is a mesh reinforcing rib, and the other is a groove extending along the length of the seat cushion. By providing the first reinforcing structure 80 and the second reinforcing structure 90 on the seat cushion base plate 30, the structural strength of the seat cushion base plate 30 is further improved, so that the seat cushion base plate 30 can better provide support for the seat cushion body 100, passengers, and drivers, which is beneficial to improving the service life of the seat cushion. The use of mesh reinforcing ribs increases the bending and torsional resistance of the seat cushion base plate 30 on the side facing the seat cushion body 100, effectively distributing and bearing the pressure from the driver and passengers and various loads generated during vehicle operation, preventing the base plate from deforming or breaking under heavy pressure, and ensuring the structural stability and load-bearing capacity of the seat cushion. The groove design extending along the length of the seat cushion can significantly improve the tensile strength of the seat cushion base plate 30, especially when subjected to dynamic loads in the front and rear directions during vehicle operation. This design helps maintain the shape of the base plate under long-term use and complex road conditions, preventing damage caused by long-term stretching.

[0097] Furthermore, the distribution of the mesh reinforcing ribs and grooves provides clear reference and support for the installation of other components such as the sensor assembly 40 and the buffer 60, ensuring the accuracy and stability of the installation position. In addition, this design also facilitates easier identification and access to components under the base plate during maintenance and inspection, simplifying maintenance work.

[0098] In some alternative embodiments, the present invention also provides an electric vehicle including the aforementioned seat cushion. By optimizing the contact surfaces between the seat cushion and the human body, particularly the shape and support of the seat portion 10 and the leg rest portion 20, a more comfortable and healthy riding experience is provided for the driver. The junction of the first seat surface 111 and the second seat surface 112 serves as the lowest point of the seat cushion, and the ratio of the width of the leg rest portion 20 to the width of the seat portion 10 is controlled to ensure that the driver's buttocks and thighs receive proper support, while the legs have sufficient space and the correct support angle, reducing fatigue during long-distance driving.

[0099] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
