Description

Technical Field

[0001] This utility model relates to the field of two-wheeled vehicle seat technology, and in particular to an adaptive adjustable seat cushion. Background Technology

[0002] Current electric two-wheeler seat cushions generally have the following problems:

[0003] Insufficient comfort: Traditional saddles often use a single-density sponge material, which cannot provide differentiated support according to the pressure distribution of different parts of the body. Long-term riding can easily lead to fatigue and soreness in the buttocks and lower back. At the same time, the surface of the saddle has poor breathability, and in hot weather, the rider's buttocks are prone to sweating, making them stuffy and uncomfortable.

[0004] Poor adaptability: The fixed shape and size of the saddle make it difficult to meet the needs of riders of different body types. Heavier riders may feel that the saddle is too small and provides insufficient support; while thinner riders may feel that the saddle is too large and lacks a sense of enclosure, affecting riding stability.

[0005] Limited functionality: Existing saddles only provide basic load-bearing capacity and lack additional functions such as heating and shock absorption, making them unsuitable for different usage scenarios and climate conditions. For example, in cold weather, the saddle is icy cold, severely impacting the riding experience; when riding on bumpy roads, the saddle cannot effectively cushion vibrations, exacerbating riding discomfort. Utility Model Content

[0006] In response to the shortcomings of the existing production technology, the applicant provides a structurally sound adaptive adjustment seat cushion that can automatically adjust support strength, contact temperature, breathability, and other properties to improve user comfort.

[0007] The technical solution adopted in this utility model is as follows:

[0008] An adaptive seat cushion includes a cushioning layer, an adaptive support layer, and a breathable adjustment layer.

[0009] The buffer layer is located on the frame; the adaptive support layer and the breathability adjustment layer are located above the buffer layer.

[0010] The adaptive support layer includes a sponge portion and an airbag portion; the sponge portion includes several pieces of sponge bonded together and an elastic support strip lining or under the sponge; the airbag portion includes several interconnected branch airbags, all of which are supplied with air by the same air pump.

[0011] The breathable conditioning layer includes, from top to bottom, a breathable layer and a temperature-controlled breathable membrane.

[0013] The adaptive support layer and the breathable adjustment layer are stacked together, with the adaptive support layer supporting the breathable adjustment layer.

[0014] The sponge portion and airbag portion of the adaptive support layer are stacked, with the airbag portion supporting the sponge portion.

[0015] The foam section is divided into a hip support area and a thigh support area, with the foam density in the hip support area being higher than that in the thigh support area.

[0016] The airbag section is divided into a hip support airbag and a thigh support airbag. The hip support airbag and the thigh support airbag each have an air path leading out to the air pump, and the air pump is connected to a pressure sensor.

[0017] The breathable layer of the breathable conditioning layer adopts a honeycomb structure.

[0018] The breathable layer is injection molded and embedded into the surface of the seat cushion.

[0019] The heating wires are arranged in a mesh pattern; a control button is located on the side of the seat cushion, which connects to the heating wires and the vehicle's power supply.

[0020] The buffer layer includes:

[0021] Rubber cushioning blocks are adhered to the bottom edge of the seat cushion.

[0022] Shock-absorbing springs connect the frame and the seat.

[0023] The shock-absorbing springs are covered with foam.

[0036] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] like Figures 1-5 As shown, an adaptive adjustment seat cushion includes a cushioning layer 1, an adaptive support layer 2, and a breathable adjustment layer 3.

[0038] A buffer layer 1 is installed on the vehicle frame; an adaptive support layer 2 and a breathable adjustment layer 3 are installed above the buffer layer 1.

[0039] The adaptive support layer 2 includes a sponge portion and an airbag portion; the sponge portion includes several pieces of sponge bonded together and an elastic support strip lining or under the sponge; the airbag portion includes several interconnected branch airbags, all of which are supplied with air by the same air pump 205.

[0040] The breathable conditioning layer 3 includes, from top to bottom, a breathable layer 301 and a temperature-controlled breathable membrane 302.

[0041] The seat cushion is also equipped with a heating wire 4, which is electrically connected to the vehicle's power supply.

[0042] The adaptive support layer 2 and the breathable adjustment layer 3 are stacked together, with the adaptive support layer 2 supporting the breathable adjustment layer 3.

[0043] The sponge portion and the airbag portion of the adaptive support layer 2 are stacked, with the airbag portion supporting the sponge portion.

[0044] The sponge portion is divided into a hip support area 201 and a thigh support area 202, with the sponge density of the hip support area 201 being higher than that of the thigh support area 202.

[0045] The airbag section is divided into a hip support airbag 203 and a thigh support airbag 204. The hip support airbag 203 and the thigh support airbag 204 respectively lead out air passages to the air pump 205, and the air pump 205 is connected to a pressure sensor.

[0046] The breathable layer 301 of the breathable conditioning layer 3 adopts a honeycomb structure.

[0047] The breathable layer is injection molded from 301 and embedded in the surface of the seat cushion.

[0048] The heating wires 4 are arranged in a mesh or serpentine pattern; a control button 5 is provided on the side of the seat cushion, and the control button 5 is connected to the heating wires 4 and the vehicle power supply.

[0049] The buffer layer 1 includes:

[0050] Rubber cushioning block 101 is bonded to the bottom edge of the seat cushion.

[0051] Shock absorber spring 102 connects the frame and the seat.

[0052] The shock-absorbing spring 102 is covered with sponge.

[0053] The specific structure and working principle of this application are as follows:

[0054] The seat cushion of this application is an improvement on the conventional seat cushion, with the addition of an adaptive support layer 2, a breathable adjustment layer 3, and a multi-functional module.

[0055] The specific structure of the adaptive support layer 2 is as follows:

[0056] The seat cushion has an elongated oval structure, divided into upper and lower layers. The upper layer is a zoned sponge with variable firmness, and the lower layer is an air cushion layer.

[0057] like Figure 2 As shown, the structure of the foam section is as follows: the interior of the seat cushion is divided into a hip support area 201 and a thigh support area 202. Each area uses a combination of foam of different densities and elastic support strips. The hip support area 201 uses high-density slow-rebound foam, the thigh support area 202 uses medium-density foam, and the lumbar support area is equipped with an elastic support strip composed of memory metal and flexible rubber. This partitioned design and material selection constitute unique protection points, aiming to provide differentiated support according to the pressure distribution of different parts of the body.

[0058] Among them, the elastic support strips are made of materials such as TPU and EVA, and are pasted on the inside of the sponge to support the sponge and obtain different degrees of soft support or medium support.

[0059] like Figure 3As shown, the lower airbag structure is as follows: a thigh support airbag 204 is installed on the side of the seat cushion near the front of the vehicle; a hip support airbag 203 is installed on the bottom surface of the seat cushion. The thigh support airbag 204 is elongated and fills the thick side wall of the seat cushion; the hip support airbag 203 is planar and covers the entire bottom surface of the seat cushion.

[0060] Both the thigh support airbag 204 and the hip support airbag 203 are composed of several interconnected branch airbags made of silicone rubber, allowing for simultaneous adjustment of support during inflation and deflation. Both airbags are connected to the same miniature air pump 205 via air delivery tubes. The miniature air pump 205 has a rated voltage of 48V and is connected to the vehicle control system via wires. Pressure sensors are installed at both the thigh support airbag 204 and the hip support airbag 203. These sensors monitor the rider's pressure distribution in real time and transmit the detected pressure data to the vehicle control system. The control system then uses a preset algorithm to control the air pump 205 to inflate or deflate the miniature airbags.

[0061] As an alternative implementation, a structure with a sponge layer at the bottom and an airbag layer at the top can also be used. (Refer to the reference...) Figure 1 When the sponge layer is placed below the airbag layer, a shock-absorbing spring 102 is installed inside the sponge layer for auxiliary support.

[0062] The shock absorber spring 102 is made of 60Si2Mn spring steel and undergoes heat treatment to improve its elasticity and strength. The spring compression is designed according to the vehicle's shock absorption requirements.

[0063] In one embodiment of this application, the sponge layer is divided into multiple areas, which are glued together to form the filling material of the seat cushion body.

[0064] like Figure 5 As shown, the breathable conditioning layer 3 is attached to the upper surface of the sponge layer. The specific structure of the breathable conditioning layer 3 is as follows: a honeycomb breathable layer 301 is adopted, and the honeycomb structure is obtained by injection molding process; a temperature-controlled breathable membrane 302 is set between the sponge layer and the breathable layer 301.

[0065] The breathable layer 301 is made of lightweight plastic, with a micro-rotor diameter of 2mm, and is injection molded into the seat cushion surface. The temperature-controlled breathable membrane 302 is made of shape memory polymer material, which automatically expands or contracts its micropores according to the seat cushion temperature to regulate airflow and temperature. The temperature-controlled breathable membrane 302 is bonded to the internal sponge of the seat cushion through a hot-pressing process. The micropores of the temperature-controlled breathable membrane 302 are in a contracted state at 25℃, and gradually expand as the temperature rises, reaching their maximum expansion state at 35℃.

[0066] In one embodiment of this application, the hexagonal pore size in the honeycomb breathable layer 301 ranges from 4 to 6 mm, and can be either 4 mm or 6 mm at the endpoints, or 5 mm in the middle. The pore spacing ranges from 7 to 9 mm, and can be either 7 mm or 9 mm at the endpoints, or 8 mm in the middle.

[0067] Since the temperature-controlled breathable membrane 302 needs to sense the internal and external temperatures of the seat cushion for adjustment, it is preferable to place the temperature-controlled breathable membrane 302 on the upper layer of the seat cushion, which is only covered by the honeycomb breathable layer 301.

[0068] like Figure 4 As shown, the seat cushion in this embodiment is also equipped with a heating module. The heat source is a carbon fiber heating wire 4 with a diameter of 0.5mm. The heating wire 4 is connected to the control button 5 on the side of the seat cushion and the vehicle power supply through an insulated wire. The control button 5 is waterproof.

[0069] The carbon fiber heating wire 4 is embedded within the seat cushion and distributed in a mesh pattern. Theoretically, as long as the carbon fiber heating wire 4 does not damage other components during heating, it can be installed on any layer. Considering heat exchange efficiency, in this application, the carbon fiber heating wire 4 is preferably installed near the surface of the seat cushion, for example, above or below the temperature-controlled breathable membrane 302.

[0070] The heating temperature of the carbon fiber heating wire 4 can be adjusted to three levels—low temperature (20℃), medium temperature (30℃), and high temperature (50℃)—using the control button 5 on the side of the seat cushion.

[0071] As a further optimization scheme, such as Figure 2 As shown, a shock-absorbing spring 102 and a rubber buffer block 101 are installed between the seat and the frame. The shock-absorbing spring 102 is a helical compression spring. A rubber buffer block 101 can also be installed at the edge of the seat base. The rubber buffer block 101 is made of natural rubber, formed through a vulcanization process, and is fixed to the edge of the seat base using strong adhesive during installation. Together, they constitute a buffer structure for absorbing the impact of road bumps.

[0072] The advantage of this application is that it can simultaneously control the support hardness, temperature, and breathability of the seat cushion, and also provide a significant cushioning effect, resulting in a better user experience.

[0073] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
