Description

Technical Field

[0001] This utility model relates to the field of seat cushions, and in particular to a seat cushion structure for a two-wheel drive vehicle. Background Technology

[0002] In the motorcycle manufacturing industry, traditional techniques for installing and securing the seat often involve adhesive bonding to connect the seat to the frame. This method is widely used in the industry due to its simplicity and low cost. It involves applying adhesive to the area where the seat contacts the frame, using the adhesive's strength to bond the two together, thus quickly completing the motorcycle seat assembly.

[0003] However, as motorcycles age and are affected by vibrations and bumps during riding, the drawbacks of seats fixed by adhesive bonding become apparent. Over time, the adhesive strength gradually decreases, and combined with the complex mechanical forces involved in motorcycle riding, the seat is prone to shifting. This shifting not only affects rider comfort but can also lead to changes in riding posture, increasing safety hazards. Furthermore, frequent shifting causes wear and tear at the connection between the seat and the frame, reducing the seat's lifespan and increasing maintenance costs. Summary of the Invention

[0004] In order to improve the service life of the seat cushion and reduce its wear during use, this utility model provides a seat cushion structure for a two-wheel drive vehicle.

[0005] This utility model provides a technical solution that adopts the following approach:

[0006] A seat structure for a two-wheel drive vehicle includes a groove disposed on the top of the frame and a seat cushion disposed within the groove. The groove extends through the frame along the width direction. A first positioning member and a second positioning member are provided between the groove and the seat cushion. The first positioning member restricts the seat cushion from moving along the width direction of the frame, and the second positioning member restricts the seat cushion from moving along the length direction of the frame.

[0007] When installing the saddle, align the saddle and the groove, and then fix the saddle with glue or other adhesive. This allows the first and second positioning parts to be installed together, restricting the movement of the saddle in both the length and width directions of the frame. This dual restriction of the saddle in both the width and length directions of the frame effectively prevents saddle displacement, reduces wear at the joints, and significantly extends the saddle's lifespan. At the same time, the stable saddle position ensures riding comfort and safety, and reduces user maintenance costs.

[0008] Furthermore, the groove runs through the frame, allowing the seat to extend partially to cover the connection between the top surface and the side wall of the frame. When the driver sits on the bike, the seat cushions the friction between the top surface and the connection, making the driver's riding experience better.

[0009] Preferably, the first positioning member includes a protrusion on the bottom wall of the groove, and the seat cushion has a slot on the side near the groove. The two sides of the protrusion and the two sides of the frame width direction respectively form clearance grooves for the two side walls of the seat cushion to be inserted.

[0010] The saddle and the mounting groove interlock through protrusions and clearance grooves, restricting the saddle's movement along the width of the frame while increasing the contact area between the saddle and the frame, thus improving the connection's strength. This design also distributes the pressure on the saddle during riding, preventing damage caused by excessive localized stress.

[0011] Preferably, the first positioning member includes a raised strip on the upper surface of the protrusion, the raised strip extending along the length direction of the frame, and the slot having a strip groove on the inner wall of the protrusion for the raised strip to fit into.

[0012] The raised slats and grooves fit together along the width of the frame, further enhancing the lateral positioning capability of the seat. When the vehicle encounters crosswinds, tilts, or makes emergency maneuvers, this structure effectively resists lateral impacts, preventing lateral displacement of the seat. Simultaneously, the tight fit between the raised slats and grooves increases the contact area and friction between them. Furthermore, the cooperation between the raised slats and grooves ensures quick and accurate alignment of the seat with the grooves, reducing stress unevenness caused by installation deviations, and further improving the seat's fixation strength and lifespan in the width direction.

[0013] Preferably, the second positioning member includes an insert block disposed on the bottom wall of the seat cushion and an insertion groove disposed on the bottom wall of the recess, wherein the insert block is integrally connected to the two side walls of the slot.

[0014] The insert block works with the slot to assist in positioning and installing the saddle while restricting the saddle's movement along the length of the frame. Placing the insert block on the saddle can thicken the saddle in certain areas and connect the two sides of the saddle, which helps reduce saddle deformation and prevents the saddle from opening up and separating from the frame.

[0015] Preferably, the second positioning member further includes a limiting block disposed in the clearance groove, and the seat cushion is provided with limiting grooves that cooperate with the limiting block at the two inner side walls of the slot, and the limiting block has inclined guide surfaces on both sides along the length direction of the frame.

[0016] The guide surfaces on both sides of the limiting block can help the limiting groove and the limiting block to be aligned and installed, while further limiting the movement of the seat in the length direction of the frame, making the seat less likely to shift along the length direction of the frame.

[0017] Preferably, the seat cushion includes an inclined portion and a horizontal portion, the shape of the slot is adapted to the shape of the seat cushion, and the limiting groove and the insert are respectively provided in the inclined portion and the horizontal portion.

[0018] Some motorcycles have an inclined buffer section at the end of the seat near the front of the vehicle, followed by a horizontal section for the driver to ride normally. Therefore, the seat is designed accordingly, with the two limiting structures of the second positioning member located on the inclined and horizontal sections respectively. This allows the connection and limiting structures between the seat and the frame to be evenly distributed along the length of the seat, further reducing seat deformation.

[0019] Preferably, the limiting groove is located at one end of the inclined portion near the horizontal portion.

[0020] The limiting block and limiting groove are located at the connection between the horizontal and inclined parts, which can support the transition of the seat cushion and make the seat cushion less prone to deformation.

[0021] Preferably, the guide surface of the limiting block on the side away from the horizontal part is parallel to the horizontal part.

[0022] Preferably, the insert protrudes from the lower surface of the horizontal portion.

[0023] The insertion depth of the insert into the frame is greater than the insertion depth of the saddle into the frame, which helps to increase the movement restriction of the saddle in the length direction of the frame, making the connection between the saddle and the frame more stable.

[0024] In summary, this utility model has the following beneficial technical effects:

[0025] When installing the saddle, align the saddle and the groove, and then fix the saddle with glue or other adhesive. This allows the first and second positioning parts to be installed together, restricting the movement of the saddle in both the length and width directions of the frame. This dual restriction of the saddle in both the width and length directions of the frame effectively prevents saddle displacement, reduces wear at the joints, and significantly extends the saddle's lifespan. At the same time, the stable saddle position ensures riding comfort and safety, and reduces user maintenance costs.

[0026] Furthermore, the groove runs through the frame, allowing the seat to extend partially to cover the connection between the top surface and the side wall of the frame. When the driver sits on the bike, the seat cushions the friction between the top surface and the connection, making the driver's riding experience better. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0032] This utility model discloses a seat structure for a two-wheel drive vehicle.

[0033] Reference Figure 1 as well as Figure 2 A seat structure for a two-wheel drive vehicle includes a groove 2 located on the top of a frame 1 and a seat 3 located within the groove 2. The groove 2 extends through the frame 1 along its width direction. A first positioning member and a second positioning member are provided between the groove 2 and the seat 3. The first positioning member restricts the seat 3 from moving along the width direction of the frame 1, and the second positioning member restricts the seat 3 from moving along the length direction of the frame 1.

[0034] When installing the saddle 3, align the saddle 3 with the groove 2 and then fix the saddle 3 with glue or other adhesive. This allows the first positioning component and the second positioning component to be installed together, restricting the movement of the saddle 3 in the length and width directions of the frame 1. The saddle 3 is doubly limited in both the width and length directions of the frame 1, effectively preventing the saddle 3 from shifting, reducing wear at the connection points, and significantly extending the service life of the saddle 3. At the same time, the stable position of the saddle 3 ensures riding comfort and safety, and reduces user maintenance costs.

[0035] Furthermore, the groove 2 penetrates through the frame 1, allowing the seat 3 to partially extend to cover the connection between the top surface and the side wall of the frame 1. When the driver sits on the vehicle, the seat 3 cushions the friction between the top surface and the connection, making the driver's riding experience better.

[0036] Reference Figure 2 as well as Figure 3 In this embodiment, the first positioning member includes a protrusion 4 provided on the bottom wall of the groove 2, and a slot 5 is provided on the side of the seat cushion 3 near the groove 2. The two sides of the protrusion 4 and the two sides of the frame 1 in the width direction respectively form a clearance groove 6 for the two side walls of the seat cushion 3 to be inserted.

[0037] The saddle 3 and the groove 2 are interlocked and fitted together by the protrusion 4 and the clearance groove 6. This design restricts the movement of the saddle 3 along the width of the frame 1 while increasing the connection area between the saddle 3 and the frame 1, thereby improving the stability of the connection. At the same time, this design can also distribute the pressure on the saddle 3 during riding, preventing damage caused by excessive local stress.

[0038] Reference Figure 2 as well as Figure 3 In this embodiment, the first positioning member includes a protrusion 7 on the upper surface of the protrusion 4. The protrusion 7 extends along the length direction of the frame 1. The slot 5 has a strip groove 8 on the inner wall of the protrusion 4 for the protrusion 7 to fit into.

[0039] The raised slat 7 and the groove 8 fit together along the width of the frame 1, further enhancing the lateral positioning capability of the seat cushion 3. When the vehicle encounters crosswinds, tilts, or makes emergency maneuvers, this structure effectively resists lateral impacts, preventing lateral displacement of the seat cushion 3. Simultaneously, the tight fit between the raised slat 7 and the groove 8 increases the contact area and friction between them. Furthermore, the cooperation between the raised slat 7 and the groove 8 ensures quick and accurate alignment of the seat cushion 3 with the groove 2, reducing stress unevenness caused by installation deviations and further improving the fixation strength and service life of the seat cushion 3 in the width direction.

[0040] Reference Figure 2 as well as Figure 3 In this embodiment, the second positioning member includes an insert block 9 disposed on the bottom wall of the cushion 3 and an insertion groove 10 disposed on the bottom wall of the groove 2. The insert block 9 is integrally connected to the two side walls of the slot 5.

[0041] The insert 9 cooperates with the insertion slot 10 to assist in the positioning and installation of the seat 3 while restricting the movement of the seat 3 along the length of the frame 1. The insert 9 is placed on the seat 3, which can thicken the seat 3 in some parts and connect the two sides of the seat 3. This helps to reduce the deformation of the seat 3 and reduce the situation where the two sides of the seat 3 open up and separate from the frame 1.

[0042] Reference Figure 2 as well as Figure 3 In this embodiment, the second positioning member also includes a limiting block 11 disposed in the clearance groove 6. The seat cushion 3 is provided with a limiting groove 12 that cooperates with the limiting block 11 at the two inner side walls of the slot 5. The limiting block 11 has inclined guide surfaces on both sides along the length direction of the frame 1.

[0043] The guide surfaces on both sides of the limiting block 11 can assist the limiting groove 12 in aligning with the limiting block 11 during installation, while further restricting the movement of the seat cushion 3 in the length direction of the frame 1, making the seat cushion 3 less likely to shift along the length direction of the frame 1.

[0044] Reference Figure 2as well as Figure 3 In this embodiment, the seat cushion 3 includes an inclined portion 13 and a horizontal portion 14. The shape of the slot 5 is adapted to the shape of the seat cushion 3. The limiting groove 12 and the insert 9 are respectively provided on the inclined portion 13 and the horizontal portion 14.

[0045] Some motorcycles have an inclined buffer section at the end of the seat near the front of the vehicle, and a horizontal section behind the buffer section for the driver to ride normally. Therefore, the seat 3 is adapted to be set up so that the two limiting structures of the second positioning member are respectively set on the inclined part 13 and the horizontal part 14. This allows the connection and limiting structure between the seat 3 and the frame 1 to be evenly distributed in the length direction of the seat 3, further reducing the deformation of the seat 3.

[0046] Reference Figure 2 as well as Figure 3 In this embodiment, the limiting groove 12 is provided at one end of the inclined portion 13 near the horizontal portion 14.

[0047] The limiting block 11 and the limiting groove 12 are located at the connection between the horizontal part 14 and the inclined part 13, which can support the transition point of the seat cushion 3, making the seat cushion 3 less prone to deformation.

[0048] Reference Figure 2 as well as Figure 3 In this embodiment, the guide surface of the limiting block 11 on the side away from the horizontal part 14 is parallel to the horizontal part 14.

[0049] Reference Figure 2 as well as Figure 3 In this embodiment, the insert 9 protrudes from the lower surface of the horizontal portion 14.

[0050] The insertion depth of the insert 9 into the frame 1 is greater than the insertion depth of the seat 3 into the frame 1, which helps to increase the movement restriction of the seat 3 in the length direction of the frame 1, making the connection between the seat 3 and the frame 1 more stable.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
