Description

[Technical field]

[0001] The present invention relates to a seat mounting structure for an electric vehicle. [Background technology]

[0002] Conventionally, a vehicle seat is known in which the seat cushion is supported so as to be freely swingable relative to a storage box, starting from the rear end of the seat cushion, and the seat cushion is attached to a storage box by engaging a second engagement portion provided at the front end of the seat cushion with a second engaged portion of the storage box.

[0003] In this vehicle seat, in order to easily remove the seat cushion from the storage box and improve the ease of storing items in the storage box, the second engaging portion is loosely engaged with the second engaged portion so as to only allow upward movement of the seat cushion, making it easy to attach and detach the seat cushion from the storage box.

[0004] [Patent Document 1] JP 2012-162120 A Summary of the Invention [Problem to be solved by the invention]

[0005] Meanwhile, in the case of vehicle seats for electric vehicles used by people with weak legs and hips, such as the elderly, the seat cushion is designed to be easily detachable from the vehicle body for users who are concerned about the seat cushion getting dirty or deteriorating when the vehicle is parked outdoors. Therefore, there is a risk that the seat cushion may come off due to strong winds such as typhoons, tornadoes, or gusts of wind. To prevent this from happening, the seat cushion must be firmly attached to the storage box.

[0006] One way to firmly attach the seat cushion to the vehicle body is to tighten and fix the seat cushion to the storage box using fastening members such as bolts and brackets. However, this method is not preferred because it requires brackets, makes it difficult to attach and remove the seat cushion, and is less easy to operate.

[0007] Therefore, there is a need for a seat mounting structure for an electric vehicle that can prevent the seat cushion from coming off the electric vehicle with a simple configuration without sacrificing operability that allows even elderly people with little strength to easily attach and detach the seat.

[0008] The present invention has been made in light of the above-mentioned circumstances, and has an object to provide a seat mounting structure for an electric vehicle that can firmly fix a seat cushion to a seat frame with a simple configuration. [Means for solving the problem]

[0009] The present invention is a seat mounting structure for an electric vehicle in which a seat having a seat cushion on which a driver sits and a seat back arranged above the rear end of the seat cushion to serve as a backrest for the driver is mounted to a seat frame, the seat cushion having a cushion rubber attached to an underside thereof, the cushion rubber having an engagement portion that engages with the seat frame, and the seat cushion being mounted to the seat frame by the cushion rubber. Effect of the Invention

[0010] As described above, according to the present invention, the seat cushion can be firmly fixed to the seat frame with a simple structure. [Brief description of the drawings]

Stopper pieces 30A, 30B, 30C, and 30D are provided symmetrically on the lower surface of the left and right portions of the bottom plate 30, respectively, and stopper pieces 30A to 30D protrude downward from the bottom plate 30.

[0046] 7 is a diagram showing the seat cushion 21 in the middle of being attached or detached, and shows a state in which a cushion rubber 35 (described later) is brought close to the seat frame 13. FIG.

[0047] The stopper pieces 30A are formed in a plate shape extending in the left-right direction, and the left and right stopper pieces 30A are configured so that their outer ends on the vehicle side face opposite to and can abut against the inner surfaces of the left and right side frame portions 17, 18. The stopper pieces 30A position the seat cushion 21 relative to the seat frame 13 in the vehicle width direction.

[0048] The stopper piece 30B is formed in a plate shape along the front-rear direction, and its rear end faces the front surfaces of the left and right cushion brackets 26A and is capable of abutting against the front surfaces of the cushion brackets 26A. The stopper piece 30C is formed in a plate shape along the front-rear direction, and its front end faces the rear surfaces of the left and right cushion brackets 26A and is capable of abutting against the rear surfaces of the cushion brackets 26A.

[0049] The stopper piece 30D is formed in a plate shape extending in the left-right direction, faces the front surfaces of the left and right cushion brackets 26B, and is capable of abutting against the front surfaces of the cushion brackets 26B.

[0050] As shown in FIG. 6, a gap 31 is formed between the rear end of the stopper piece 30B and the cushion bracket 26A, and a gap 32 is formed between the front end of the stopper piece 30C and the rear surface of the cushion bracket 26A.

[0051] As a result, when attaching the seat cushion 21 to the seat frame 13, the seat cushion 21 is allowed to be positioned in the fore-and-aft direction within the range of the gaps 31, 32, improving the ease of assembly and allowing the seat cushion 21 to be positioned in the fore-and-aft direction relative to the seat frame 13.

[0052] FIG. 3 shows a state in which the rear end of the stopper piece 30B is abutted against the front end of the cushion bracket 26A and the rear end of the cushion bracket 26A is brought close to the front end of the stopper piece 30C, thereby positioning the seat cushion 21 in the fore-and-aft direction relative to the seat frame 13.

[0053] Furthermore, the rear surface of the stopper piece 30D is brought into contact with the front surface of the cushion bracket 26B to determine the position in the front-rear direction.

[0054] 3, a cushion rubber 35 is provided on the bottom plate 30 of the seat cushion 21. That is, the cushion rubber 35 is attached to the lower surface of the seat cushion 21, and is disposed on both left and right ends of the seat cushion 21.

[0055] 5, an abutment surface that comes into surface contact with the bottom plate 30 is formed at the upper end of the cushion rubber 35, and an insertion portion 35A is provided so as to protrude from this abutment surface. The insertion portion 35A is inserted into and engaged with a hole formed in the bottom plate 30, and the cushion rubber 35 is attached to the bottom plate 30 by this engagement.

[0056] As shown in FIG. 3, the front end of the cushion rubber 35 is located forward of the front ends of the side handle portions 14 and 15.

[0057] In other words, in this embodiment, the front ends of the side frame portions 17, 18 are located forward of the front ends of the side handle portions 14, 15, the front end of the cushion rubber 35 is located forward of the front ends of the side handle portions 14, 15, and the rear end of the cushion rubber 35 is located rearward of the front ends of the side handle portions 14, 15.

[0058] As shown in Fig. 5, an engagement portion 35a is formed on the cushion rubber 35 on the side frame portion 17 side. The cushion rubber 35 on the side frame portion 17 side and the cushion rubber 35 on the side frame portion 18 side are formed to be the same shape, and Fig. 5 shows the cushion rubber 35 on the side frame portion 17 side.

[0059] The engaging portion 35a has a surface that conforms to the outer shape of the side frame portions 17, 18, and is configured as a recess that receives the side frame portions 17, 18. The cushion rubber 35 is integrally formed from an elastic member, and the engaging portion 35a is elastically deformable.

[0060] In other words, the cushion rubber 35 has an upper portion that is sandwiched between the bottom plate 30 and the upper surfaces of the side frame portions 17, 18 above the side frame portions 17, 18, and an engagement portion 35a that wraps around to the lower sides of the side frame portions 17, 18 and engages with the side frame portions 17, 18.

[0061] When the seat cushion 21 is attached to the side frame portions 17, 18, the engaging portions 35a elastically deform to receive the side frame portions 17, 18, and engage with the side frame portions 17, 18. The engaging portions 35a engage with the side frame portions 17, 18 so as to bias the side frame portions 17, 18 outward from the vehicle.

[0062] The seat cushion 21 has its rear end inserted into the space under the seat back 22 and the engagement portion 35a of the cushion rubber 35 provided at the front end engaging with the side frame portions 17, 18, so that the rear end is held by the seat back 22 and the front end engages with the seat frame 13 to be attached to the electric vehicle 1.

[0063] 7, protrusions 35b and 35c are formed on the lower end 35u of the cushion rubber 35. The protrusion 35b is formed on the front end of the lower end 35u of the cushion rubber 35, and protrudes downward from the lower end 35u of the cushion rubber 35.

[0064] As shown in FIG. 5, the lower end 35u of the cushion rubber 35 is composed of a horizontal surface 35m on the lower surface of the cushion rubber 35 and an inclined surface 35n that extends obliquely from the horizontal surface 35m toward the side frame portions 17, 18 and on which the protrusions 35b, 35c are formed.

[0065] The protruding portion 35c is formed at the rear end of the lower end portion 35u of the cushion rubber 35, and protrudes downward from the lower end portion 35u of the cushion rubber 35. In other words, the protruding portions 35b, 35c are spaced apart from each other in the front-rear direction of the cushion rubber 35.

[0066] The engagement portion 35a of the cushion rubber 35 engages with the side frame portions 17, 18 from the central portion 34 side in the vehicle width direction of the electric vehicle 1.

[0067] Of the lower end 35u of the cushion rubber 35, the lower portion of the inclined surface 35n and the horizontal surface 35m are located below the side frame portion 17. The lower end 35u of the cushion rubber 35 may be located below the side frame portion 17. In other words, the horizontal surface 35m and the inclined surface 35n may be located below the side frame portion 17.

[0068] 5, the lower end 35u of the cushion rubber 35 is visible from a gap 36 between the seat cushion 21 and the rear lifting handle 11. Alternatively, the lower end 35u of the cushion rubber 35 is disposed so as to be visible from a space in front of the rear lifting handle 11.

[0069] Specifically, as shown in FIG. 5, both left and right sides of the bottom plate 30 are bent downward from the horizontally extending bottom plate surface of the bottom plate 30, and both sides of the seat cushion 21 have bent portions 21A bent downward from the seat cushion 21 (although FIG. 5 shows the left side of the seat cushion 21, the right side of the seat cushion 21 has the same shape as the left side).

[0070] The side frame portions 17 and 18 are provided at the same height as the bent portion 21A, and are disposed on the rear side of the bent portion 21A. A gap 36 is formed between the lower end portion 21a of the bent portion 21A and the side handle portions 14 and 15 in the vertical direction.

[0071] When the engagement portion 35a of the cushion rubber 35 is engaged with the side frame portions 17, 18, the cushion rubber 35 is positioned at the same height as the side frame portions 17, 18, and the lower end portion 35u of the cushion rubber 35 is visible through the gap 36 between the lower end portion 21a of the folded portion 21A and the side handle portions 14, 15.

[0072] As shown in FIG. 4, cushion rubbers 44 are provided on both the left and right sides of the seat cushion 21 behind the cushion rubber 35.

[0073] The upper end of the cushion rubber 44 is formed with a contact surface that comes into surface contact with the bottom plate 30, and the insertion portion 44A is provided so as to protrude from this contact surface. The insertion portion 44A is inserted into and engaged with a hole formed in the bottom plate 30, and the cushion rubber 35 is attached to the bottom plate 30 by this engagement.

[0074] The cushion rubber 44 is placed on the side frame portions 17, 18 when the seat cushion 21 is attached to the electric vehicle 1. The cushion rubber 44 is made of an elastic material, and is sandwiched between the bottom plate 30 and the upper surfaces of the side frame portions 17, 18 on the upper sides of the side frame portions 17, 18.

[0075] That is, the front side of the seat cushion 21 of this embodiment is attached to the side frame parts 17, 18 via the cushion rubber 35, and the rear side is placed on the side frame parts 17, 18 via the cushion rubber 44 between the rear end part of the seat cushion 21 and the cushion rubber 35. This allows the seat cushion 21 to stably support the weight of the driver.

[0076] Next, the effect of the seat mounting structure of the electric vehicle 1 according to this embodiment will be described. The seat cushion 21 is attached to the electric vehicle 1 by inserting the rear end into the space under the seat back 22, and then moving the front side of the seat cushion 21 from above to below and engaging the engagement portion 35a of the cushion rubber 35 with the side frame portions 17, 18.

[0077] The mounting structure of the seat 10 of the electric vehicle 1 of this embodiment is such that the seat 10 has a seat cushion 21 on which the driver sits and a seat back 22 that is positioned above the rear end of the seat cushion 21 and serves as a backrest for the driver, and is mounted on a seat frame 13.

[0078] In addition, the mounting structure of the seat 10 of the electric vehicle 1 has a cushion rubber 35 attached to the bottom plate 30 of the seat cushion 21. The cushion rubber 35 has an engagement portion 35a that engages with the side frame portions 17, 18, and the seat cushion 21 is mounted to the side frame portions 17, 18 by the cushion rubber 35.

[0079] This allows the elastic force of the cushion rubber 35 to press the engagement portions 35a against the side frame portions 17, 18 with a strong force, and the seat cushion 21 can be firmly fixed to the seat frame 13 with a simple structure.

[0080] As a result, the seat cushion 21 can be prevented from coming off the side frame portions 17, 18 due to strong winds such as typhoons, tornadoes, or gusts of wind.

[0081] Furthermore, according to the mounting structure for seat 10 of electric vehicle 1 of this embodiment, engaging portion 35a made of elastic material has a surface that follows the outer shape of side frame portions 17, 18, and is configured as a recess that receives side frame portions 17, 18. Therefore, engaging portion 35a adheres closely to the outer surfaces of side frame portions 17, 18, and can be prevented from coming off.

[0082] In addition, the lower end 35u of the cushion rubber 35 has protrusions 35b, 35c that protrude from the lower end 35u, and the protrusions 35b, 35c come into contact with the side frame portions 17, 18 when the cushion rubber 35 is attached to the side frame portions 17, 18.

[0083] As a result, with regard to the cushion rubber 35, which is made of an elastic material and therefore tends to stick to the outer surfaces of the side frame portions 17, 18, the contact area of ​​the cushion rubber 35 when attaching the seat cushion 21 to the side frame portions 17, 18 can be reduced, thereby reducing the frictional force between the cushion rubber 35 and the side frame portions 17, 18. This improves the attachment performance when attaching the seat cushion 21 to the side frame portions 17, 18.

[0084] In addition, when attaching the seat cushion 21 to the side frame portions 17, 18, the frictional force between the cushion rubber 35 and the side frame portions 17, 18 can be reduced, so that the cushion rubber 35 is prevented from being subjected to excessive load or deformation when the seat cushion 21 is attached, thereby improving the durability of the cushion rubber 35.

[0085] Furthermore, since the protrusions 35b, 35c are formed to protrude, when the engaging portion 35a engages with the side frame portions 17, 18, the amount of elastic deformation that the cushion rubber 35 undergoes to return to its original state can be increased, allowing the engaging portion 35a to be more firmly engaged with the side frame portions 17, 18.

[0086] Furthermore, according to the mounting structure of the seat 10 of the electric vehicle 1 of this embodiment, the cushion rubber 35 is mounted on the left and right sides of the front part of the seat cushion 21, and the engagement portions 35a of the cushion rubber 35 engage with the side frame portions 17, 18 from the central portion 34 side in the vehicle width direction of the electric vehicle 1.

[0087] In addition, at least a portion of the lower end 35u of the cushion rubber 35 is located lower than the side frame portions 17, 18.

[0088] As a result, when removing the seat cushion 21 from the electric vehicle 1, the lower end portion 35u of the cushion rubber 35 can be pushed toward the central portion 34 in the vehicle width direction of the electric vehicle 1 from the outside in the vehicle width direction of the electric vehicle 1, so that the engagement portion 35a can be easily released even if it is firmly engaged with the side frame portions 17, 18.

[0089] In particular, the engaging portions 35a of the cushion rubber 35 that have stuck to the outer surfaces of the side frame portions 17, 18 can be peeled off from the side frame portions 17, 18.

[0090] In addition, when the lower end portion 35u of the cushion rubber 35 is pushed toward the central portion 34 in the vehicle width direction to release the engagement, since the protrusions 35b, 35c are formed protruding from the lower end portion 35u, tools or the like can be caught thereon, improving operability.

[0091] Therefore, the seat cushion 21 can be firmly attached to the electric vehicle 1 by the cushion rubber 35, and the workability when removing the seat cushion 21 from the electric vehicle 1 can be improved.

[0092] Furthermore, according to the mounting structure of the seat 10 of the electric vehicle 1 of this embodiment, the seat cushion 21 has a rear lifting handle 11 arranged on the outer periphery of the seat cushion 21, and the lower end 35u of the cushion rubber 35 is visible between the seat cushion 21 and the rear lifting handle 11.

[0093] This prevents the cushion rubber 35 from being blocked from view by the rear lifting handle 11, and allows the cushion rubber 35 to be seen from outside in the vehicle width direction of the electric vehicle 1.

[0094] Therefore, the cushion rubber 35 can be easily accessed from the outside in the vehicle width direction of the electric vehicle 1, and the workability when removing the seat cushion 21 from the electric vehicle 1 can be more effectively improved.

[0095] Although an embodiment of the invention has been disclosed, it will be apparent to one of ordinary skill in the art that modifications may be made therein without departing from the spirit and scope of the invention, and it is intended that all such modifications and equivalents be included in the following claims.
