Description

[Technical Field]

[0001] The present invention relates to a movable driver's seat. [Background technology]

[0002] In conventional vehicles, the engine and transmission are located approximately in the center of the vehicle width for reasons of stability and the like.

[0003] In recent years, electric vehicles (EVs), which are equipped with motors instead of engines, have come into practical use. Because EVs do not require an engine or transmission, the space that would have been occupied by the engine can be used for other purposes.

[0004] In vehicles such as trucks, the space inside the cab can be used more effectively by eliminating the engine that was previously located under the cab. One idea for effectively utilizing the space inside the cab is to place the driver's seat in the center of the vehicle width. By placing a single driver's seat in the center of the vehicle width inside the cab, weight and costs can be reduced.

[0005] It is already known that a driver's seat is located in the center of a vehicle width direction. For example, Patent Document 1 discloses a configuration in which a driver's seat is located in the center of a vehicle width direction and can be rotated around a rotation center located behind the driver's seat, making it easy for passengers to get in and out of the vehicle.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-12866 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in this conventional method of locating the driver's seat in the center of the vehicle width, the driver's seat is fixed in the center of the cab, which is inconvenient as it requires the driver to move around inside the cab when paying tolls or receiving tickets at toll booths, or when getting in or out of the vehicle. Moving around inside the cab is particularly inconvenient for elderly or disabled drivers.

[0008] The present invention was invented with a focus on such problems, and aims to provide a structure that makes it easier for the driver to move around inside the vehicle cab. [Means for solving the problem]

[0009] The present invention has been made to solve at least part of the above problems, and can be realized as the following aspects or application examples in a driver's seat arranged in the center of a vehicle in the width direction.

[0010] The movable driver's seat according to this application example comprises a rail section provided on the floor inside the vehicle's cab and extending in the vehicle width direction, a first movement mechanism section that can move along the rail section, and a driver's seat attached to the first movement mechanism section, and the first movement mechanism section moves along the rail section to move the driver's seat in the vehicle width direction.

[0011] According to this application example, the first movement mechanism moves along the rail portion to move the driver's seat in the vehicle width direction within the cab, which allows the driver to move in the vehicle width direction without standing up and moving within the cab, which is highly convenient.

[0012] In the movable driver's seat according to this application example, it is preferable that the first movement mechanism unit positions the driver's seat in the center in the vehicle width direction when the vehicle is traveling.

[0013] In this case, by locating one driver's seat in the center of the vehicle width direction within the cab, it is possible to reduce weight and costs.

[0014] In addition, in the movable driver's seat according to this application example, it is preferable that a second movement mechanism be provided between the first movement mechanism and the driver's seat, the second movement mechanism being capable of moving the driver's seat in the forward or backward direction of the vehicle, and the first movement mechanism be configured to move the second movement mechanism and the driver's seat in the vehicle width direction along the rail portion. In this case, the driver can adjust the driving position by moving the driver's seat in the forward or backward direction.

[0015] In addition, in the movable driver's seat according to this application example, it is preferable that the movement of the first movement mechanism along the rail portion is suppressed while the vehicle is traveling. In this case, safety during traveling can be maintained. [Effects of the Invention]

[0016] According to this embodiment, it is possible to facilitate movement within the cab for the driver, thereby improving convenience. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] An embodiment of the present invention will be described with reference to the drawings. This embodiment is merely an example, and is not intended to exclude various modifications or application of techniques not explicitly described in the following embodiment. Each configuration of this embodiment can be implemented with various modifications within the scope of the spirit thereof. Furthermore, it is possible to select and / or combine as needed.

[0019] [1. Configuration] Fig. 1 is a perspective view from the front of a vehicle 1 equipped with an adjustable driver's seat 2 according to one embodiment, Fig. 2 is a perspective view from the side, and Fig. 3 is a perspective view from above. Fig. 4 is a three-view diagram of the adjustable driver's seat 2 shown in Figs. 1 to 3, where (A) is a plan view, (B) is a front view, and (C) is a side view.

[0020] 1, 2, 6 and 7, a movable driver's seat 2 mounted on a vehicle 1 is shown by a solid line, and other parts are shown by virtual lines (two-dot chain lines). In addition, in this embodiment, a truck will be exemplified as the vehicle 1 for explanation.

[0021] In the following description, the forward direction of the vehicle 1 is referred to as the forward direction FR, and the opposite direction (the backward direction of the vehicle) is referred to as the backward direction RR. The left and right (left direction LH and right direction RH) are defined based on the state in which the vehicle is facing forward FR. The forward and backward direction is also referred to as the vehicle length direction, and the left and right direction is also referred to as the vehicle width direction. Furthermore, the direction perpendicular to both the vehicle length direction and the vehicle width direction is referred to as the up and down direction (upward direction UP and downward direction DN). The vehicle is assumed to be on a level road surface and to be in a position in which the up and down direction coincides with the vertical direction (the downward direction coincides with the direction of gravity). In this position, the vertically upward direction is referred to as the height direction.

[0022] 2 and 3, a steering wheel 11 is disposed in a front position in a cab 1a of a vehicle 1, near the center in the vehicle width direction. The cab 1a is an example of a cab of a vehicle 1. A brake pedal, an accelerator pedal, and the like (not shown) are also disposed at the feet around the steering wheel 11. A single movable driver's seat 2 is mounted behind the steering wheel 11.

[0023] The movable operator's seat 2 has a seat body 20, a front-rear movement mechanism 3, and left-right movement mechanisms 4a, 4b. The left-right movement mechanisms 4a, 4b are installed on the floor of the cab 1a, and the front-rear movement mechanism 3 is attached above the left-right movement mechanisms 4a, 4b. Furthermore, the seat body 20 is disposed above the front-rear movement mechanism 3. The seat body 20 is an example of an operator's seat.

[0024] When the seat body 20 is in a central position in the left-right direction and is located behind the steering wheel 11 so that the driver seated on the seat body 20 can operate the steering wheel 11, the position of the seat body 20 can be called the driving position (first position).

[0025] As shown in Figures 1, 2, 4(B) and 4(C), the seat body 20 has a seat cushion 21 and a seat back 22. The seat cushion 21 has a substantially rectangular shape and is disposed substantially parallel to the floor surface of the cab 1a with one side facing forward. The seat back 22 may be configured to be reclining.

[0026] An obstacle detection sensor 50 is attached to each of the left and right sides of the seat cushion 21. The obstacle detection sensor 50 detects obstacles to the left and right of the seat cushion 21. The obstacle detection sensor 50 may be, for example, a sonar sensor, an ultrasonic sensor, a millimeter-wave radar, or the like.

[0027] When the seat body 20 is moved leftward or rightward by the left-right movement mechanism 4 described below, the obstacle detection sensor 50 detects any obstacles in the direction of travel. A detection signal from the obstacle detection sensor 50 is input to a control device (not shown). When the obstacle detection sensor 50 detects an obstacle, the control device stops the movement by the left-right movement mechanism 4. The control device may notify the driver that an obstacle has been detected by displaying a warning on a monitor attached to the instrument panel or the like, or by outputting a warning sound.

[0028] A front-rear movement mechanism 3 is attached to the underside of the seat cushion 21. The front-rear movement mechanism 3 moves the seat body 20 in the front-rear direction inside the cab 1a. The front-rear movement mechanism 3 is provided between the movement mechanism unit 51 and the seat body 20, and is an example of a second movement mechanism unit that can move the seat body 20 in the forward or backward direction of the vehicle 1.

[0029] The front-rear movement mechanism 3 has a front-rear rail portion 31 and a front-rear slide portion 32, as shown in, for example, FIGS.

[0030] The front and rear rail portions 31 are multiple (two in this embodiment) elongated members extending in the front and rear direction and parallel to each other (see Figure 3), and the front and rear slide portions 32 are slidably engaged with each of these front and rear rail portions 31.

[0031] The front-rear sliding section 32 is formed, for example, in a generally U-shaped cross section with an opening on the bottom, and is attached to the front-rear rail section 31 with the front-rear rail section 31 sandwiched between the openings. This allows the front-rear sliding section 32 to be guided by the front-rear rail section 31 and slide in the front-rear direction.

[0032] The bottom surface (lower side surface) of the seat cushion 21 of the seat body 20 is fixed to the upper part of the front-rear sliding portion 32. Therefore, the seat body 20 is configured to be slidable in the front-rear direction while being guided by the front-rear rail portion 31.

[0033] The longitudinal sliding section 32 is also provided with a fixing mechanism (not shown), which allows the longitudinal sliding section 32 to be fixed at any position on the longitudinal rail section 31. This allows the seat body 20 to be positioned at any position in the fore-aft direction inside the cab 1a. The fixing mechanism for the longitudinal sliding section 32 can be realized using various known methods, and a description thereof will be omitted.

[0034] The left-right movement mechanism 4 moves the seat body 20 in the left-right direction inside the cab 1a. In this embodiment, for example, as shown in Figures 2, 3, and 4(A) and (C), two left-right movement mechanisms 4 are provided. These left-right movement mechanisms 4 are arranged parallel to each other along the vehicle width direction (left-right direction) on the flat floor surface of the cab 1a. Of these left-right movement mechanisms 4, the left-right movement mechanism 4 arranged at the front may be referred to as left-right movement mechanism 4a, and the left-right movement mechanism 4 arranged at the rear may be referred to as left-right movement mechanism 4b. These left-right movement mechanisms 4a and 4b have similar configurations. Hereinafter, when there is no need to particularly distinguish between the left-right movement mechanisms 4a and 4b, they will be referred to as left-right movement mechanism 4.

[0035] The left-right movement mechanism 4 has left-right rail portions 41 and a movement mechanism portion 51 .

[0036] The left and right rail portions 41 are elongated rail members laid on the floor surface of the cab 1a and extending in the left-right direction. The left and right rail portions 41 are an example of rail portions extending in the vehicle width direction on the floor surface of the cab 1a of the vehicle 1.

[0037] Figure 5 shows the left-right movement mechanism 4 of the movable driver's seat 2 in one embodiment, where (A) is a side cross-sectional view of the left-right movement mechanism 4 and (B) is a partial top view of the movement mechanism part 51 of the left-right movement mechanism 4.

[0038] 5(A), the left and right rail portions 41 have a cross-sectional shape that is roughly a horizontal H. Therefore, as shown in FIGS. 5(A) and 5(B), grooves 411 are formed along the left and right direction on the front and rear surfaces of the left and right rail portions 41, respectively, over almost the entire left and right direction.

[0039] The movement mechanism 51 is engaged with the left and right rail portions 41 and moves left and right inside the cab 1a along the left and right rail portions 41. The movement mechanism 51 is an example of a first movement mechanism that is movable in the vehicle width direction along the left and right rail portions 41.

[0040] The front-rear movement mechanism 3 and the seat body 20 are attached to the upper part of the movement mechanism part 51, and the movement mechanism part 51 thereby moves the seat body 20 in the left-right direction in the cab 1a.

[0041] The movement mechanism 51 includes, for example, a drive roller 43, a driven roller 44, and a motor 45, as shown in FIGS.

[0042] The drive roller 43 is a roller that rotates around a shaft 46 disposed along the vertical direction, and is configured so that its outer circumferential surface (roller surface) abuts against the vertical surface at the back of a groove 411 formed in one surface (the front surface in this embodiment) of the left or right rail portion 41. The shaft 46 is rotatably supported on the upper and lower sides of the drive roller 43 by support plates 48 that are horizontally disposed, respectively.

[0043] The outer circumferential surface of the drive roller 43 is desirably formed to have a high coefficient of friction. The outer circumferential surface of the drive roller 43 may be covered with a material having a high coefficient of friction, such as rubber. Furthermore, the drive roller 43 may be pressed against the vertical surface of the groove 411.

[0044] A motor 45 is attached to the shaft 46 of the drive roller 43, and the drive roller 43 rotates in accordance with the rotation of the motor 45. In the example shown in Fig. 5, the shaft 46 and the rotating shaft of the motor 45 may be connected via a power transmission mechanism such as a gear, although this is not shown, and various modifications can be made.

[0045] The driven roller 44 is a roller that rotates around a shaft 47 that is disposed along the vertical direction, and is configured so that its outer circumferential surface (roller surface) abuts against the vertical surface at the back of a groove 411 formed in the other surface (the rear surface in this embodiment) of the left and right rail portions 41. The shaft 47 is rotatably supported above and below the drive roller 43 by support plates 48 that are disposed horizontally.

[0046] It is desirable that the outer circumferential surface of the driven roller 44 is also formed to have a high coefficient of friction. The outer circumferential surface of the driven roller 44 may be covered with a material with a high coefficient of friction, such as rubber. Furthermore, the driven roller 44 may be pressed toward the vertical surface of the groove 411. The driven roller 44 is disposed in a position facing the drive roller 43 across the left and right rail portions 41. The combination of the drive roller 43 and the driven roller 44 facing each other across the left and right rail portions 41 may be referred to as a roller pair. In this embodiment, as shown in FIG. 4(A) etc., one movement mechanism unit 51 is provided with two roller pairs.

[0047] In the roller pair configured in this manner, by rotating the drive roller 43 in a first rotation direction by the motor 45, the movement mechanism 51 is guided by the left and right rail portion 41 and moves in a first direction (for example, to the right) between the left and right. Also, by rotating the drive roller 43 in a second rotation direction opposite to the first rotation direction by the motor 45, the movement mechanism 51 is guided by the left and right rail portion 41 and moves in a second direction opposite to the first direction (for example, to the left).

[0048] Furthermore, by stopping the motor 45, the moving mechanism unit 51 can be fixed (locked) on the left and right rail units 41. Instead of fixing the moving mechanism unit 51 by the motor 45, a fixing mechanism for fixing (locking) the position of the moving mechanism unit 51 on the left and right rail units 41 may be provided.

[0049] The rotation of the motor 45 may be controlled by the driver operating an operation switch (not shown) provided in the cab 1a. The operation switch may be located, for example, on the instrument panel (center panel), and may be modified as appropriate.

[0050] For example, the driver may use an operation switch to select the position of the seat body 20 from among the center position, the right position, and the left position in the left-right direction.

[0051] The initial position of the seat body 20 may be set in advance to one of the center position, the right side, or the left side in the left-right direction. For example, the control device may move the seat body 20 to the set initial position after confirming that the driver has exited the vehicle. The initial position of the seat body 20 may be set using a monitor on the center panel or the like.

[0052] Furthermore, while the vehicle 1 is traveling, the left-right movement mechanism 4 is locked, and movement of the movement mechanism unit 51 in the left-right direction on the left-right rail unit 41 is inhibited. In other words, while the vehicle 1 is traveling, movement of the movement mechanism unit 51 along the left-right rail unit 41 is inhibited. This ensures safety while traveling. Whether the vehicle 1 is traveling may be determined based on, for example, the vehicle speed or the state of the parking brake. For example, the control device may determine that the vehicle 1 is traveling when the vehicle speed is equal to or greater than a predetermined threshold. The control device may also determine that the vehicle 1 is traveling when the parking brake is not applied.

[0053] The drive roller 43, the driven roller 44, the motor 45, etc. are surrounded by a cover 42. This cover 42 can prevent foreign objects such as the driver's clothes or hands and feet from coming into contact with or getting caught in the drive roller 43, the left and right rail portions 41, etc.

[0054] The bottom of the front-rear rail section 31 is fixed to the upper surface of the cover 42. As a result, as the movement mechanism section 51 moves left and right, the front-rear movement mechanism 3 and the seat body 20 attached to this front-rear movement mechanism 3 also move left and right.

[0055] As shown in Figures 1, 3, and 4(A) and (B), a movement completion detection switch 49 is attached to each of the left and right sides of the cover 42. The movement completion detection switch 49 is a switch that detects that the movement mechanism unit 51, which moves on the left and right rail units 41, has reached a predetermined position (movement completion position). A known positioning switch such as a touch switch may be used as the movement completion detection switch 49. The movement completion position may be the limit position of the range of motion of the movement mechanism unit 51. For example, the left end position and the right end position of the left and right rail units 41 may be set as the movement completion positions, respectively.

[0056] When the left-right movement mechanism 4 moves the seat body 20 leftward or rightward, the movement completion detection switch 49 detects when the movement mechanism unit 51 reaches a movement completion position. The detection signal from the movement completion detection switch 49 is input to a control device (not shown). When the control device detects that the movement completion detection switch 49 has reached the movement completion position, it stops the movement by the left-right movement mechanism 4. In other words, when the seat body 20 has moved to the full extent of the movable range of the left-right rail units 41, its movement is stopped.

[0057] [2. Actions and Effects] In vehicle 1, the driver in the vehicle performs an input operation via the operating switch to move the seat body 20 to the end position on the door side (e.g., the right side) when, for example, paying a toll or receiving a ticket at a toll booth or the like, or when getting off the vehicle.

[0058] In response to this input operation, the control unit controls the rotation of the motor 45, causing the motor 45 to rotate the drive roller 43 in the first rotation direction. As a result, the movement mechanism unit 51 is guided by the left and right rail units 41 and moves in the first direction (for example, to the right).

[0059] Additionally, as the movement mechanism 51 moves, the front-rear movement mechanism 3 and the seat body 20 fixed to the movement mechanism 51 are also guided by the left-right rail portion 41, and the driver sitting in the seat body 20 also moves in the first direction (for example, to the right). The movement mechanism 51 moves along the left-right rail portion 41, thereby moving the front-rear movement mechanism 3 (second movement mechanism) and the seat body 20 (driver's seat) in the vehicle width direction.

[0060] When the movement mechanism 51 moving on the left and right rail portions 41 reaches a movement completion position (for example, the right end position of the left and right rail portions 41), the movement completion detection switch 49 turns on, and it is detected that the movement mechanism 51 has reached the movement completion position. The detection signal from the movement completion detection switch 49 is input to a control device (not shown), and the control device stops the movement by the left and right movement mechanism 4.

[0061] This allows the driver to move to one end of the vehicle width direction while sitting in the seat body 20 inside the cab 1a, and is highly convenient as he can pay the fare, receive the ticket, etc. without having to stand up and move around the cab 1a.

[0062] Furthermore, when the obstacle detection sensor 50 detects an obstacle in the traveling direction while the seat body 20 is moving on the left and right rail portions 41, the obstacle detection sensor 50 outputs a detection signal. The detection signal output from the obstacle detection sensor 50 is input to the control device. When the obstacle detection sensor 50 detects an obstacle, the control device stops the movement by the left and right movement mechanism 4.

[0063] The control device notifies the driver that an obstacle has been detected by displaying a warning on a monitor attached to the instrument panel or by outputting a sound indicating the warning. The driver may remove the obstacle and then perform an input operation via the operation switch again to move the seat body 20 to the end position on the door side (for example, to the right side).

[0064] When the driver drives the vehicle 1, the driver performs an input operation to move the seat body 20 to the driving position (center position) via an operation switch. The operation switch for moving the seat body 20 to the driving position (center position) may be provided, for example, at the left and right end positions of the instrument panel of the vehicle 1, near both side doors of the vehicle 1, on the seat body 20, etc.

[0065] In response to this input operation, the control unit controls the motor 45 to cause the motor 45 to rotate the drive roller 43 in the second rotation direction. As a result, the movement mechanism unit 51 is guided by the left and right rail units 41 to move in the second direction (for example, to the left) and move to the driving position. As the movement mechanism unit 51 moves, the front-rear movement mechanism 3 and the seat body 20 fixed to the movement mechanism unit 51 are also guided by the left and right rail units 41, and the driver sitting in the seat body 20 also moves to the driving position. When the vehicle 1 is traveling, the movement mechanism unit 51 positions the seat body 20 in the center in the vehicle width direction.

[0066] This provides great convenience for the driver, as he or she can move to the driving position while remaining seated in the seat body 20. Furthermore, by locating one seat body 20 in the center of the vehicle width direction within the cab 1a, it is possible to reduce weight and costs.

[0067] The front-rear movement mechanism 3 is arranged above the left-right movement mechanism 4, and this front-rear movement mechanism 3 moves while being guided by the left-right rail parts 41 by the movement mechanism part 51 of the left-right movement mechanism 4, so the function of the front-rear movement mechanism 3 is not hindered and the driver can move the seat body 20 in the front-rear direction as desired to adjust the driving position.

[0068] When the left-right movement mechanism 4 moves the seat body 20 leftward or rightward, the obstacle detection sensor 50 detects any obstacles in the direction of travel. If the obstacle detection sensor 50 detects an obstacle, the control device stops the movement by the left-right movement mechanism 4. This prevents the movement mechanism 51 from coming into contact with obstacles while it is moving on the left and right rails 41, ensuring safety.

[0069] Furthermore, while the vehicle 1 is traveling, the left-right movement mechanism 4 is locked, and the movement mechanism unit 51 is prevented from moving left and right on the left and right rail units 41. This ensures safety while the vehicle is traveling.

[0070] [3. Other] 6 and 7 are diagrams illustrating other configurations of a vehicle 1 equipped with the movable driver's seat 2 shown in the above embodiment, where FIG. 6 shows the configuration of a foldable passenger seat 6 provided in the cab 1a, and FIG. 7 shows the state in which the foldable passenger seat 6 is in use.

[0071] 6 and 7, in addition to the vehicle 1 shown in Fig. 2, a foldable passenger seat 6 is installed. Specifically, in the cab 1a, the foldable passenger seats 6 are provided on both the left and right sides of the seat body 20 in the driving position, on the rear inner wall (cab back) of the cab 1a.

[0072] The folding passenger seat 6 includes a seat cushion 61 and a seat back 62, and the seat cushion 61 is configured to be foldable relative to the seat back 62. The folded state of the seat cushion 61 may be referred to as the stored state, and the unfolded state of the seat cushion 61 may be referred to as the unfolded state. In the folding passenger seat 6 illustrated in FIG. 6, the stored state of the seat cushion 61 is indicated by a solid line, and the unfolded state of the seat cushion 61 is indicated by a dashed line. Furthermore, while the seat cushion 61 remains in the stored state stored in the seat back 62, the passenger seat 6 may be rotated 90 degrees, for example, so as to align with the left door.

[0073] 7, a passenger can sit in the front passenger seat 6. In other words, the foldable front passenger seat 6 can accommodate an increased number of passengers.

[0074] Furthermore, by storing the folding passenger seat 6, even when the seat body 20 of the movable driver's seat 2 is moved left and right, the passenger seat 6 does not interfere with the seat body 20, which moves while being guided by the left and right rail portions 41.

[0075] FIG. 8 is a three-view diagram illustrating another configuration of the adjustable driver's seat 2 shown in the above embodiment, where (A) is a plan view, (B) is a front view, and (C) is a side view.

[0076] The movable driver's seat 2 illustrated in FIG. 8 includes a substantially rectangular plate-like member 7 between the left-right movement mechanism 4 and the front-rear movement mechanism 3 in addition to the configuration of the movable driver's seat 2 illustrated in FIG.

[0077] In the movable driver's seat 2 illustrated in FIG. 4, the bottom surface (lower side surface) of the seat cushion 21 of the seat body 20 is fixed to the upper portion of the front-rear sliding portion 32.

[0078] In contrast, in the movable driver's seat 2 shown in Figure 8, the front and rear rail portions 31 of the front and rear movement mechanism 3 are fixed to the upper surface of the plate-shaped member 7, and the lower surface of this plate-shaped member 7 is fixed to the upper surface of the cover 42 of the left and right movement mechanism 4.

[0079] In this way, the structure for connecting the left-right movement mechanism 4 and the front-rear movement mechanism 3 can be implemented in various modified forms.

[0080] In the above-described embodiment, one moving mechanism unit 51 is provided with two roller pairs, but this is not limited to this. One moving mechanism unit 51 may be provided with one or three or more roller pairs.

[0081] Furthermore, some of the roller pairs among the plurality of roller pairs provided in the movement mechanism unit 51 may be provided with driven rollers 44 instead of the drive roller 43. That is, some of the roller pairs may be configured so that the left and right rail units 41 are sandwiched between two driven rollers 44. For example, if the torque of the motor 45 or the power transmission force of the drive rollers 43 is sufficient, some of the roller pairs may be provided with driven rollers 44 instead of the drive rollers 43 and the motor 45 may be omitted, thereby reducing manufacturing costs.
