Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to an anti-submarine sliding structure, a seat cushion skeleton, a seat and a vehicle. Background Art

[0002] In the prior art, the anti-submarine sliding structure in a vehicle seat forms an anti-submarine sliding structure by combining a square tube or a round tube with a seat basin, so that the seat has an anti-submarine effect. However, the existing anti-submarine sliding structure of the seat has a high cost and poor seat comfort. The seat basin in the existing anti-submarine sliding structure only plays a supporting role and does not integrate any fixing methods for functional components, with a relatively single function. The space utilization rate under the seat basin is low, which is not conducive to increasing the seat configuration or compressing the seat cushion height value (Block value) of the seat. Due to the setting of the anti-submarine sliding tube of the seat, the sheet metal directly above the seat basin needs to be provided with an upward convex feature structure to avoid the anti-submarine sliding tube. The seat cushion foam thickness at the raised structure of the seat basin sheet metal is small, so that the part of the seat cushion opposite to the raised structure of the seat basin sheet metal when a passenger is sitting is more likely to feel hard points relative to other areas of the seat cushion, affecting the riding comfort of the passenger and resulting in a poor riding experience for the passenger.

[0041] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. Below, reference is made to Figures 1 - 9 Describe the anti-submarine sliding structure 20 according to an embodiment of the present utility model, including: a seat pan 21 and a seat pan reinforcement plate 22. The anti-submarine sliding structure 20 has a first direction A, a second direction B, and a third direction C.

[0042] Specifically, as Figures 1 - 9 shown, the seat pan reinforcement plate 22 is provided on the seat pan 21, and the seat pan reinforcement plate 22 and the seat pan 21 jointly define an anti-submarine sliding cavity 23 therebetween.

[0043] Combined with Figures 4 - 9 , the seat pan reinforcement plate 22 is disposed above the seat pan 21 along the first direction A of the anti-submarine sliding structure 20. The seat pan reinforcement plate 22 is fixedly connected to the seat pan 21, and a certain space is defined between the seat pan reinforcement plate 22 and the seat pan 21, which is the anti-submarine sliding cavity 23.

[0044] According to the anti-submarine sliding structure 20 of the embodiment of the present utility model, the seat basin 21 is fixedly connected to the seat basin reinforcement plate 22. The seat basin 21 can play a role in fixing and supporting the seat basin reinforcement plate 22, improving the overall structural strength of the anti-submarine sliding structure 20. The anti-submarine sliding structure 20 is arranged in the seat 100. The anti-submarine sliding cavity 23 jointly defined between the seat basin reinforcement plate 22 and the seat basin 21 plays a role in preventing downward diving, so as to prevent the passengers from moving forward too much or diving when being collided, thereby achieving the purpose of protecting the passengers in the vehicle and effectively improving the safety of the passengers when taking the seat. The setting of the anti-submarine sliding cavity 23 replaces the anti-submarine sliding tube structure, so that the protruding features on the seat basin 21 or the supporting surface of the seat basin 21 are not restricted by the spatial layout of the anti-submarine sliding tube. Therefore, the structures such as the protruding features of the seat basin 21 or the supporting surface of the seat basin 21 can be designed lower, effectively improving the MTM (MEAT TO MENTAL) value at the anti-submarine sliding part of the seat cushion, reducing the hard point feeling of the passengers on the protruding structure on the seat basin 21 on the seat cushion, and improving the riding comfort of the passengers.

[0045] According to some embodiments of the present utility model, as Figures 6 - 9 shown, the seat basin 21 has a first anti-submarine sliding part 211 recessed away from the seat basin reinforcement plate 22, and the seat basin reinforcement plate 22 has a second anti-submarine sliding part 221 recessed away from the seat basin 21. The second anti-submarine sliding part 221 and the first anti-submarine sliding part 211 jointly constitute the anti-submarine sliding cavity 23. The first anti-submarine sliding part 211 is formed by a part of the seat basin 21 recessing away from the seat basin reinforcement plate 22 along the first direction A of the anti-submarine sliding structure 20, and the second anti-submarine sliding part 221 is formed by the first part of the seat basin reinforcement plate 22 recessing away from the seat basin 21 along the first direction A of the anti-submarine sliding structure 20. A certain space is defined between the first anti-submarine sliding part 211 and the second anti-submarine sliding part 221, that is, the anti-submarine sliding cavity 23. The setting of the anti-submarine sliding cavity 23 replaces the anti-submarine sliding tube structure. The protruding structure design of the second anti-submarine sliding part 221 of the seat basin 21 is not restricted by the spatial layout of the anti-submarine sliding tube and can be designed lower, effectively improving the MTM value at the anti-submarine sliding part of the seat cushion and enhancing the riding comfort of the passengers. Thus, the setting of the first anti-submarine sliding part 211 and the second anti-submarine sliding part 221 facilitates the seat basin 21 and the seat basin reinforcement plate 22 to define the anti-submarine sliding cavity 23. The cooperation between the first anti-submarine sliding part 211 and the second anti-submarine sliding part 221 can enhance the structural strength of the anti-submarine sliding cavity 23. The structures of the first anti-submarine sliding part 211 and the second anti-submarine sliding part 221 replace the anti-submarine sliding tube structure, which is beneficial to reducing the production cost of the anti-submarine sliding structure 20 and facilitating the wide application of the anti-submarine sliding structure 20.

[0046] According to some embodiments of the present utility model, as Figure 5 and Figure 6As shown, the first anti-submarine sliding part 211 is located at the middle rear end of the seat basin 21, and the second anti-submarine sliding part 221 is located at the middle front end of the seat basin reinforcement plate 22. The first anti-submarine part is located at the middle rear end of the seat basin 21 along the second direction B, and the second anti-submarine sliding part 221 is located at the middle front end of the seat basin reinforcement plate 22 along the second direction B. The first anti-submarine sliding part 211 and the second anti-submarine sliding part 221 are arranged oppositely along the first direction A. The length of the seat basin reinforcement plate 22 in the second direction B is smaller than the length of the seat basin 21 in the second direction B. When the seat basin reinforcement plate 22 is fixed on the seat basin 21, the seat basin reinforcement plate 22 is arranged at the middle rear part of the seat basin 21 along the second direction B. The first anti-submarine sliding part 211 and the second anti-submarine sliding part 221 are arranged at the middle rear part of the anti-submarine sliding structure 20 along the second direction B, which is also convenient for installing other components of the system at the front part of the anti-submarine sliding structure 20 along the second direction B, reserving space for the installation of other components, such as leg rest and other structures, to improve the riding experience of passengers.

[0047] Thus, the anti-submarine sliding cavity 23 jointly defined by the first anti-submarine sliding part 211 and the second anti-submarine sliding part 221 is located at the middle rear end of the seat basin 21 along the second direction B. When a passenger is collided, the setting of the anti-submarine sliding cavity 23 can prevent the center of gravity of the passenger from diving downward and will not cause a lifting movement, enhancing the protection of the passenger. The first anti-submarine sliding part 211 is arranged at the middle rear end of the seat basin 21 along the second direction B. The second anti-submarine sliding part 221 is arranged closer to the passenger along the first direction A. The second anti-submarine sliding part 221 is arranged at the middle front section of the seat basin reinforcement plate 22 along the second direction B, and is also arranged oppositely to the middle rear end of the seat basin 21. The contact time between the second anti-submarine sliding part 221 and the passenger is longer. When the vehicle is collided, the human body leans forward under the action of inertia. The first anti-submarine sliding part 211 can support the second anti-submarine sliding part 221. The second anti-submarine sliding part 221 deforms downward or forward, so that the human body has a downward and forward displacement amount without sliding forward, preventing the passenger's feet from hitting the vehicle's dashboard or the head and chest from hitting the steering wheel, causing greater harm, and reducing the harm caused by the waist part of the seat belt to the passenger's abdomen during diving, enhancing the protection effect on the passenger.

[0048] According to some embodiments of the present invention, as Figure 7 and Figure 8 shown, the anti-submarine sliding cavity 23 extends along the left-right direction. The left-right direction is the third direction C of the anti-submarine sliding structure 20. The anti-submarine sliding cavity 23 extends along the third direction C. One end of the anti-submarine sliding cavity 23 along the third direction C is communicated with the other end, forming an integral space. Thus, the anti-submarine sliding cavity 23 extends along the third direction C, which can make the distribution of the anti-submarine sliding cavity 23 in the third direction C more comprehensive, make the protection effect of the anti-submarine sliding structure 20 on the passenger more comprehensive, prevent the anti-submarine sliding structure 20 from failing to protect the passenger when the passenger rolls over during the collision process, and enhance the safety of the anti-submarine sliding structure 20.

[0049] According to some embodiments of the present utility model, as Figure 7 shown, the toilet bowl reinforcing plate 22 has a ventilation structure mounting portion 222. The ventilation structure mounting portion 222 is disposed at the rear end of the toilet bowl reinforcing plate 22 relative to the anti-slip cavity 23. The ventilation structure mounting portion 222 is located behind the anti-slip cavity 23 along the second direction B. The setting of the ventilation structure mounting portion 222 facilitates the installation of the ventilation structure 11. Thus, the ventilation structure mounting portion 222 is used to install and fix the ventilation structure 11. The ventilation structure mounting portion 222 is integrated on the toilet bowl reinforcing plate 22, which can reduce the independent brackets for assisting the installation and fixation of the ventilation structure 11, facilitate the installation of the channel structure, improve the integration and functionality of the anti-slip structure 20, and can enhance the comfort of the user experience.

[0050] According to some embodiments of the present utility model, as Figure 7 shown, a ventilation opening 223 is formed on the ventilation structure mounting portion 222. The ventilation opening 223 penetrates through the toilet bowl reinforcing plate 22 along the first direction A of the toilet bowl reinforcing plate 22. Thus, the ventilation opening 223 is used for the circulation of cold air or hot air, so that the anti-slip structure 20 can generate a certain air flow, thereby enabling the user to obtain a more comfortable sitting experience in an environment with a lower or higher temperature.

[0051] According to some embodiments of the present utility model, as Figure 7 shown, a plurality of mounting holes 224 are formed on the ventilation structure mounting portion 222. The plurality of mounting holes 224 are arranged at intervals along the circumferential direction of the ventilation opening 223. The mounting holes 224 penetrate through the toilet bowl reinforcing plate 22 along the first direction A of the toilet bowl reinforcing plate 22. The cross-sectional area of the ventilation opening 223 is larger than the cross-sectional area of the mounting holes 224, and the plurality of mounting holes 224 surround the ventilation opening 223.

[0052] Thus, the mounting holes 224 are used to set the fasteners 13, so as to facilitate the assembly of the ventilation structure 11 on the toilet bowl reinforcing plate 22, simplify the assembly method of the ventilation structure 11 and the ventilation structure mounting portion 222, enhance the assembly strength between the ventilation structure 11 and the ventilation structure mounting portion 222, and improve the reliability and structural stability of the anti-slip structure 20.

[0053] According to some embodiments of the present utility model, as Figure 4 shown, the toilet bowl reinforcing plate 22 is welded to the toilet bowl 21. The welding process has the characteristics of high production efficiency, simple process, high connection strength, etc. The welded structure has high stiffness, good integrity and a wide range of applications. Thus, the toilet bowl reinforcing plate 22 and the toilet bowl 21 are fixedly connected by welding, which can effectively enhance the connection strength between the toilet bowl reinforcing plate 22 and the toilet bowl 21, and further enhance the overall structural strength of the anti-slip structure 20. While ensuring the stability and firmness of the anti-slip structure 20, the production cost of the anti-slip structure 20 is reduced.

[0054] According to the seat cushion frame 10 of the second aspect embodiment of the present utility model, as Figure 4 and Figure 5 shown, the seat cushion frame 10 includes: a seat pan frame 30 and an anti-submarine structure 20. The anti-submarine structure 20 is the anti-submarine structure 20 according to the above first aspect embodiment of the present utility model. The seat pan 21 of the anti-submarine structure 20 is provided on the seat pan frame 30, and the seat pan reinforcement plate 22 of the anti-submarine structure 20 is located on the side of the seat pan 21 away from the seat pan frame 30.

[0055] The anti-submarine structure 20 is provided above the seat pan frame 30 along the first direction A. Among them, the seat pan 21 of the anti-submarine structure 20 is fixedly connected to the seat pan frame 30 along the first direction A, and the seat pan reinforcement plate 22 is provided on the side of the seat pan 21 away from the seat pan frame 30 along the first direction A. The seat pan 21 and the seat pan reinforcement plate 22 are first fixedly connected by welding to form an anti-submarine cavity 23, and then assembled on the seat pan frame 30. The anti-submarine structure 20 in this embodiment is applicable to working conditions with a small BLOCK value. The anti-submarine structure 20 can also form an effective protection for passengers when receiving a frontal collision, improving safety.

[0056] According to the seat cushion frame 10 of the embodiment of the present utility model, it is convenient to realize the assembly, support and fixation of the anti-submarine structure 20, so that the seat cushion frame 10 can bear loads, transfer moments and increase stability.

[0057] According to the seat 100 of the third aspect embodiment of the present utility model, as Figures 1 - 3 shown, it includes the seat cushion frame 10 according to the above second aspect embodiment of the present utility model.

[0058] The seat 100 includes a seat cushion frame 10 and a seat cushion foam 40. The seat cushion foam 40 can be directly pressed on the upper part of the seat cushion frame 10 along the first direction A. The lower surface of the seat cushion foam 40 along the first direction A is attached to the upper surface of the seat pan reinforcement plate 22 along the first direction A. The seat cushion foam 40 is used to improve the comfort of passengers when sitting, and the seat cushion frame 10 plays a supporting role.

[0059] According to the seat 100 of the embodiment of the present utility model, by applying the seat cushion frame 10 described in the above embodiment, the comfort performance and economic performance of the seat 100 can be improved on the premise of ensuring the structural strength of the seat 100. The anti-submarine structure 20 in the seat cushion frame 10 can keep the center of gravity of passengers stable when sitting, so as to prevent the occupants from moving forward too much or diving during a collision, thereby achieving the purpose of protecting the passengers in the vehicle and improving the safety performance of the seat 100.

[0060] According to some embodiments of the present utility model, as Figures 1 - 3 and Figure 9As shown, a ventilation structure 11 is provided on the seat cushion frame 10. The ventilation structure 11 includes a fan 12. The fan 12 is provided in the ventilation structure installation part 222 of the anti-submarine sliding structure 20 of the seat cushion frame 10. The fan 12 is located on the side of the seat pan 21 of the anti-submarine sliding structure 20 of the seat cushion frame 10 away from the seat pan reinforcement plate 22, and the fan 12 is opposite to the ventilation opening 223.

[0061] The ventilation structure 11 is provided below the seat cushion frame 10 along the first direction A. The ventilation structure 11 is assembled to the ventilation structure installation part 222 of the anti-slip structure. The fan 12 is assembled to the side of the seat pan 21 away from the seat pan reinforcement plate 22 along the first direction A. The fan 12 is disposed opposite to the ventilation opening 223 on the seat pan reinforcement plate 22. The ventilation structure 11 can convey circulating air to the seat 100, effectively reducing the temperature on the surface of the seat 100, alleviating the discomfort caused by the long-term contact between the passenger's back and buttocks and the seat 100 due to the high temperature and airtightness of the seat 100 surface, keeping the seat 100 dry and clean, and making the seat 100 more comfortable.

[0062] Thus, the ventilation structure 11 provided on the seat 100 frame can effectively improve the comfort of the seat 100, providing a comfortable seating environment for passengers. The relative arrangement of the fan 12 and the ventilation opening 223 is conducive to air circulation, avoiding the use of other pipe fittings between the fan 12 and the ventilation opening 223, reducing the performance loss of air during the flow process, reducing the energy consumption of the ventilation structure 11, and also reducing the development cost of the seat 100.

[0063] According to some embodiments of the present invention, as Figure 3 and Figure 4 shown, fasteners 13 are respectively provided at multiple installation holes 224 of the ventilation structure installation part 222. The fan 12 is connected to the ventilation structure installation part 222 through the fasteners 13. One end of the fastener 13 along the extending direction is fixedly assembled in the installation hole 224, and the other end of the fastener 13 along the extending direction is adapted to be fixedly connected to the fan 12. There are multiple fasteners 13, and the multiple fasteners 13 correspond to the multiple installation holes 224 one by one. Thus, through the cooperation of the fasteners 13 and the installation holes 224, the fan 12 can be fixedly connected to the ventilation structure installation part 222, which can simplify the assembly difficulty of the fan 12, reduce the assembly cost of the fan 12. The cooperation of the multiple fasteners 13 and the multiple installation holes 224 can make the installation of the fan 12 more stable, reduce the force on each fastener 13, and extend the service life of the fasteners 13.

[0064] According to some embodiments of the present utility model, the fastener 13 is a rubber nail or a self-tapping screw. The rubber nail has the advantages of high elasticity, high air tightness, corrosion resistance, weather resistance, radiation resistance, etc. of rubber, can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes. The rubber nail has the characteristics of high pressure resistance, good elasticity, light weight, vibration reduction, convenient installation, flexible use, easy disassembly and repair, etc., and also has the characteristics of acid resistance, alkali resistance and oil resistance. The self-tapping screw has the characteristics of good internal toughness, high surface hardness, convenient assembly and low production cost, and the self-tapping screw has self-locking property, which can effectively improve the connection stability. Therefore, the fastener 13 being a rubber nail or a self-tapping screw can extend the service life of the fastener 13, ensure the installation firmness of the fan 12, and can also simplify the assembly process of the fan 12, reduce the assembly cost and maintenance cost of the fan 12.

[0065] According to some embodiments of the present utility model, as Figure 2 and 3 shown, the ventilation structure 11 further includes: an air bag 14, the air bag 14 is arranged on the side of the seat pan reinforcing plate 22 away from the seat pan 21, and the inlet of the air bag 14 is communicated with the ventilation port 223. The air bag 14 is arranged on the side of the seat pan reinforcing plate 22 away from the seat pan 21 along the first direction A, and the surface of the air bag 14 on the side away from the seat pan reinforcing plate 22 along the first direction A is adapted to contact the seat cushion foam 40. The air bag 14 is adhered to the surface of the seat cushion foam 40 on the side adjacent to the seat pan reinforcing plate 21 along the first direction A through double-sided tape, which can simplify the connection difficulty between the air bag 14 and the seat cushion foam 40, and enable the air bag 14 to achieve the heat dissipation and ventilation effects on the seat cushion foam 40.

[0066] Thus, under the action of the fan 12, the air flow flows to the ventilation port 223, and flows from the ventilation port 223 into the air bag 14. The air holes on the upper surface of the air bag 14 can convey the flowing cold air or warm air to the seat 100, adjust the temperature and humidity on the surface of the seat 100, keep the surface of the seat 100 dry and comfortable, and further improve the comfort of the passenger when sitting.

[0067] A vehicle according to an embodiment of the fourth aspect of the present utility model includes the seat 100 according to the above-mentioned third aspect embodiment of the present utility model.

[0068] The seat 100 is integrally designed as a rear-end sunken molding structure along the second direction B. The purpose is that when the vehicle is impacted from the front, in cooperation with the use of the seat belt, the anti-submarine sliding structure 20 on the seat 100 can limit the passenger on the seat 100, and generate a sinking force so that the passenger will not slide forward. In this way, the risk of the human body hitting the dashboard with the feet, the steering wheel with the head or chest due to forward sliding can be reduced, and greater damage to the cervical vertebra and spine of the human body can be prevented.
