Description

Technical Field

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

[0002] Electric vehicles have become a common mode of transportation in people's lives, providing great convenience for travel. At the same time, electric vehicles also pose many safety hazards. For example, when an electric vehicle is running but the driver is not in the driver's seat, if the driver or someone else accidentally touches the electric vehicle, it may cause the vehicle to lurch forward, ultimately resulting in damage to the vehicle or injury to people.

[0003] In other words, existing electric vehicles pose a high risk of accidental contact and potential safety hazards. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is how to reduce the safety hazards of electric vehicles caused by accidental contact.

[0005] To solve the above-mentioned technical problems, this utility model provides a sensor-activated seat cushion, comprising: a seat cushion body;

[0006] The seat base plate is located on one side of the seat body and has a mounting through hole; the sensor assembly is disposed in the mounting through hole, and one side surface of the sensor assembly is exposed on the side of the seat base plate facing the seat body, and the other side surface of the sensor assembly is exposed on the side of the seat base plate away from the seat body.

[0007] Optionally, the sensor cushion also includes multiple fasteners, the cushion base plate has multiple mounting holes, and the sensor assembly 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, and the fasteners pass through the mating holes and mounting holes. This design effectively distributes the force borne by the sensor assembly, avoiding force concentration at a single fastening point, thereby ensuring the stable operation of the sensor assembly under various working conditions.

[0008] Optionally, the seat base includes a driver's seating area, with the mounting through-hole located within the driver's seating area. The ratio of the length of the sensor assembly along the length of the sensing seat to the maximum length of the driver's seating area along the length of the sensing seat is greater than or equal to 2 / 3. This arrangement ensures that the sensor assembly has a certain detection range to guarantee detection accuracy.

[0009] Optionally, the seat cushion base plate has a raised portion that bulges towards the side where the seat cushion body is located. The raised portion has a driver seating area and a passenger seating area arranged sequentially along the length of the sensor seat cushion. By providing a raised portion on the seat cushion base plate, the raised portion increases the structural complexity of the seat cushion base plate. This structural change helps to improve the overall rigidity and strength of the base plate.

[0010] Optionally, the raised portion includes a first plate segment, a second plate segment, and a third plate segment connected sequentially along its length. The first and second plate segments are located in the driver's seating area, and the third plate segment is located in the passenger seating area. The third plate segment is located on the side of the first plate segment facing the seat cushion body. The first and second plate segments are connected in an arc shape, and the second and third plate segments are connected in an arc shape. A mounting through-hole is located in the first plate segment. This arrangement helps to improve the structural strength of the seat cushion base and also helps to distribute pressure.

[0011] Optionally, the sensor-activated seat cushion also includes multiple cushioning elements. The third plate segment has at least two mounting posts on its surface opposite to the seat cushion body. Each mounting post has a mounting groove, and the cushioning elements are detachably disposed within the mounting grooves, with at least a portion of the cushioning elements located outside the mounting grooves. This arrangement avoids subjecting the sensor-activated seat cushion to excessive stress, which not only helps ensure the lifespan of the sensor-activated seat cushion but also improves the passenger's user experience.

[0012] Optionally, the mounting post can accommodate at least two different sizes of cushioning elements. This flexibility helps optimize the internal structural configuration of the seat cushion, ensuring that comfort requirements are met without sacrificing installation space for other components.

[0013] Optionally, the seat base plate has a guide rib extending away from the seat body on the side opposite to the seat body. The guide rib is located on the raised sidewall of the raised portion, and the height of the guide rib gradually decreases towards the third plate segment. The guide rib is entirely located on the side of the seat base plate facing the seat body. By providing a guide rib on one side of the seat base plate, it is possible to ensure that the sensor seat cushion matches the seat bucket while avoiding affecting the installation space of accessories.

[0014] Optionally, the sensor-activated seat cushion also includes a sealing strip, which is located on the side of the seat cushion base away from the seat cushion body and surrounds the raised portion. The sealing strip seals the gap between the sensor-activated seat cushion and the seat tub, ensuring the seat tub's airtightness and reducing the risk of rainwater entering the seat tub.

[0015] Optionally, the surface of the seat cushion base plate facing the seat cushion body has a first reinforcing structure and a second reinforcing structure. One of the first and second reinforcing structures is a mesh reinforcing rib, and the other is a groove extending along the length of the sensor-activated seat cushion. This arrangement can further improve the structural strength of the seat cushion base plate, so that the seat cushion base plate can better support the seat cushion body, passenger, and driver, which is beneficial to improving the service life of the sensor-activated seat cushion.

[0016] This utility model also provides an electric vehicle, including the aforementioned sensor-activated seat cushion.

[0017] The sensor cushion provided by this utility model includes a cushion body, a cushion base plate, and a sensor assembly. The cushion base plate is located on one side of the cushion body and has an assembly through hole. The sensor assembly is disposed in the assembly through hole, and one side surface of the sensor assembly is exposed on the side of the cushion base plate facing the cushion body, while the other side surface of the sensor assembly is exposed on the side of the cushion base plate away from the cushion body.

[0018] The driver sits on the seat cushion itself, and the seat cushion base provides support to ensure the sensor cushion provides adequate support for both the driver and passenger. A sensor assembly is installed on the seat cushion base. The pressure detected by the sensor assembly determines whether the driver is seated, 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. This significantly reduces safety hazards and improves the safety of electric vehicle use. Exposing one side of the sensor assembly to the side of the seat cushion base facing the seat cushion itself ensures a safe distance between the sensor assembly and the seat cushion, improving the sensor's detection accuracy and preventing situations where the sensor fails to detect the driver sitting in the driver's seat.

Detailed Implementation

[0032] 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.

[0033] 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.

[0034] 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.

[0035] In order to solve the problem of high safety hazards caused by accidental contact in existing electric vehicles, this utility model provides a sensor-activated seat cushion and an electric vehicle.

[0036] like Figures 1 to 10 As shown, the sensor cushion includes a cushion body 100, a cushion base plate 30, and a sensor assembly 40. The cushion base plate 30 is located on one side of the 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 cushion base plate 30 facing the cushion body 100, while the other side surface of the sensor assembly 40 is exposed on the side of the cushion base plate 30 away from the cushion body 100.

[0037] 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 sensor cushion provides support for 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 safe 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] In some alternative embodiments, please refer to Figures 8 to 10 The 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] In some alternative embodiments, the first mounting hole 391 is located on one side of the wide side of the mounting through hole 31.

[0047] 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.

[0048] 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 sensor seat.

[0049] 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 movement to cope with different pressure load conditions and ensure the accuracy and durability of the sensor cushion in various application scenarios.

[0050] Alternatively, fastener 50 can be a screw.

[0051] In some alternative embodiments, please refer to Figure 7The 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.

[0052] In some optional embodiments, the ratio of the length of the sensor assembly 40 along the length of the sensing seat cushion to the maximum length of the driver's seating area 32 along the length of the sensing 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 the sensor assembly 40 can accurately and quickly detect pressure changes after the driver sits on the sensing seat cushion, preventing situations where the sensor assembly 40 cannot detect the driver sitting on the sensing 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 sitting posture, which is of great value in enhancing vehicle safety.

[0053] In some alternative embodiments, please refer to Figure 7 and Figure 8 The 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 sensor 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.

[0054] 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.

[0055] Meanwhile, the arrangement of the raised sections 33 takes into account the internal space planning of the sensor 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.

[0056] 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.

[0057] 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.

[0058] In some alternative embodiments, please refer to Figure 7 and Figure 8 The 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.

[0059] 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 the internal components of the sensing 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.

[0060] 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.

[0061] In some alternative embodiments, please refer to Figure 8 and Figure 9 The sensor-activated seat cushion also includes multiple cushioning elements 60. The third section 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 section 37 is relatively high, by providing cushioning elements 60 on one side of the third section 37, significant displacement at the third section 37 can be avoided when a passenger sits on the sensor-activated seat cushion. This prevents the sensor-activated seat cushion from experiencing excessive stress, which not only helps ensure the service life of the sensor-activated seat cushion but also improves the passenger's user experience.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] In some alternative embodiments, please refer to Figure 8 and Figure 9The 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 of the sensor 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.

[0066] 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.

[0067] In some alternative embodiments, please refer to Figure 8 and Figure 9The sensor-operated 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 sensor-operated 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 sensor-operated 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 sensor-operated 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.

[0068] 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.

[0069] 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 sensor 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 sensor 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 cushion. The groove design extending along the length of the sensor 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.

[0070] 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.

[0071] In some alternative embodiments, please refer to Figures 2 to 4 The sensor 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. The lowest point of the seat portion 10 and the widest position of the sensor cushion are spaced apart in the length direction of the sensor cushion.

[0072] 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 sensor seat more ergonomically designed and significantly 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 sensor seat along its length increases design flexibility, allowing for better design of the leg rest 20. This further enhances the sensor seat's comfort, optimizes legroom for the driver, and provides sufficient soft support, thus improving the overall riding experience.

[0073] exist Figure 2 In the embodiment shown, the widest position of the sensor 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 sensor cushion is the position A, the front side of the position A is the front half area of ​​the sensor cushion along the length direction, and the rear side of the position A is the rear half area of ​​the sensor cushion along the length direction.

[0074] Optionally, the seat body 100 includes a seating portion 10 and a leg support portion 20.

[0075] In some alternative embodiments, please refer to Figure 2 The widest part of the seat cushion is located in the front half of the length of the sensor-activated seat cushion. 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, where the legs naturally extend forward in a relaxed state. Therefore, placing the widest part of the sensor-activated 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 sensor-activated seat cushion's length allows for more efficient use of the space at the front of the vehicle. It maximizes comfort without compromising driver operability and safety.

[0076] In some alternative embodiments, please refer to Figure 2 The lowest point of the seat 10 is located in the rear half of the length of the sensor seat cushion. By placing the lowest point of the seat 10 behind the midpoint of the sensor 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 sensor 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.

[0077] 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 sensor-activated seat 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 sensor-activated seat provides stronger support, making the person sitting on it feel more secure. At the same time, the slightly increased height of the front of the sensor-activated seat 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.

[0078] In addition, the slightly higher front end of the sensor-activated seat cushion helps promote blood circulation in the lower limbs and reduces the risk of varicose veins. Along the length of the cushion, the lowest point of the seating 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.

[0079] In some alternative embodiments, the ratio of the sum of the widths of the two leg rests 20 at their widest positions on the sensor cushion to the widest distance L of the sensor 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.

[0080] Because the ratio of the leg rest width to the widest point of the sensor-operated 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.

[0081] The sensor-activated seat cushion provides ample leg support at its widest point, adhering to ergonomic principles as this is where the thighs naturally rest when the user sits. This design better adapts to the user's natural sitting posture, reducing discomfort and effectively improving the comfort of the sensor-activated seat cushion.

[0082] 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.

[0083] In some alternative embodiments, please refer to Figure 2 The leg support 20 gradually increases in width from the widest point of the sensor-activated 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 width of the sensor-activated seat, effectively improving the comfort of the seat. From the rear to the front of the sensor-activated 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.

[0084] By gradually increasing the width of the leg rest at the front of the sensor-activated seat cushion, the designers considered the natural tendency of the legs to extend forward when sitting. This avoids the legs suddenly encountering narrow or hard edges 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 different sitting posture preferences. Whether the user is in a standard sitting posture or prefers to spread their legs slightly, the sensor-activated seat cushion provides just the right amount of support, adapting to various sitting postures and improving the comfort and applicability of the sensor-activated seat cushion.

[0085] Furthermore, the gradually increasing width of the leg rest avoids 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 comfort and support of the sensor-activated cushion whether making slight lateral movements or crossing their legs.

[0086] In some alternative embodiments, the ratio of the width of the leg rest 20 at the narrowest position of the seat portion 10 to the width of the narrowest position of the seat portion 10 is greater than or equal to 0.8 and less than or equal to 1.2.

[0087] 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 in the range of 0.8 to 1.2. This means that the width of the leg rest is not too wide at this point, avoiding unnecessary support or pressure on the legs at the narrowest point of the sensor cushion. This precise width adjustment ensures that the leg rest fits the thighs perfectly, providing the necessary support, without affecting the comfort of other parts of the body.

[0088] In the design of sensor-activated seat cushions, the support needs of different parts of the human body vary. The width design of the leg rest takes into account the natural position and width of the thighs when seated, 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 synergy with other parts of the sensor-activated seat cushion, conforming to ergonomic principles. This allows the sensor-activated seat cushion to better adapt to the curves of the human body, reducing pressure points and discomfort that may result from prolonged sitting.

[0089] exist Figure 5 In 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.

[0090] 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 sensor 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 the connection point of the first seat surface 111 and the second seat surface 112 as the lowest point, can better adapt to the driver's sitting posture. This design ensures that the driver's buttocks and thighs are properly supported when operating the vehicle, while also helping to maintain a position conducive to controlling the steering wheel and pedals, improving driving comfort and control. The two leg rests 20 are respectively provided on both sides of the driver's seat sub-section 11, providing sufficient leg support for the driver and reducing fatigue during long-distance 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.

[0091] In some alternative embodiments, please refer to Figure 3The 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.

[0092] In some alternative embodiments, the supporting surface 21 is an arc-shaped surface, and is a concave arc surface.

[0093] 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.

[0094] 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 sensor cushion smoother and reducing potential pressure marks or discomfort caused by seams, thus improving user comfort. The continuity of the fabric also allows the sensor 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.

[0095] 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 sensor seat cushion. The one-piece cover design reduces wear points and enhances the cushion's durability. Furthermore, improved waterproofing and a simplified cleaning process make it easier for drivers and vehicle owners to keep the sensor seat cushion clean and extend its lifespan.

[0096] In some alternative embodiments, please refer to Figure 2 and Figure 3The sensor-activated 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 support 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 support portions 20. The side portion 120 is connected to both the leg support portions 20 and the seat portion 10.

[0097] Optionally, the front part 110, the seat part 10, and the leg rest part 20 are separate cover structures.

[0098] Optionally, the side portion 120, the seat portion 10, and the leg rest portion 20 are separate cover structures.

[0099] In some alternative embodiments, an electric vehicle is provided, which includes the aforementioned sensor-activated seat cushion. The sensor-activated seat cushion, through an integrated sensor assembly 40, is capable of accurately detecting whether the driver is seated correctly, which is crucial for starting the vehicle. When the sensor-activated seat cushion detects abnormal situations (such as an occupant suddenly leaving their seat or leaning forward), it can promptly notify the driver or automatically adjust the vehicle's status, thereby preventing potential traffic accidents. For example, if the vehicle's starting system detects that the driver is not seated, it may prevent the engine from starting or trigger a warning signal while driving.

[0100] 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.
