Mode for Carrying Out the Invention

[0010] Hereinafter, an embodiment of the present invention will be described with appropriate reference to the drawings.

[0011] FIG. 1 is a schematic side view showing the overall configuration of a working machine 1 according to this embodiment. In this embodiment, an example of the working machine 1 is a backhoe which is a swing working machine.

[0012] As shown in FIG. 1, the working machine 1 includes a machine body (swing platform) 2, a traveling device 3, and a working device 4. A driver's seat 6 on which an operator (driver) sits and a canopy 15 are mounted on the machine body 2. As shown in FIG. 2, the driver's seat 6 has a seat part 6A and a backrest part 6B. The seat part 6A is a part where the operator sits (places the buttocks and thighs). The backrest part 6B is a part where the seated operator leans his back, and is provided so as to extend upward at the rear of the seat part 6A. The canopy 15 is a four-pillar type canopy, and for example, may constitute a ROPS (operator protection structure).

[0013] In this embodiment, a working machine (canopy-specification working machine) 1 equipped with a canopy 15 is exemplified. However, instead of the canopy 15, a working machine (cab-specification working machine) 1 equipped with a cab surrounding the driver's seat 6 may be used, or a working machine 1 not equipped with the canopy 15 and the cab may be used.

[0014] In this embodiment, the direction towards the front of the operator seated in the operator's seat 6 of the work machine 1 (direction of arrow A1 in Figure 1) is described as the front (front of the machine), the direction towards the rear of the operator (direction of arrow A2 in Figure 1) is described as the rear (rear of the machine), and the direction of arrow A3 in Figure 1 is described as the front-rear direction (front-rear direction of the machine). Furthermore, the direction towards the left of the operator (front side in Figure 1) is described as the left, and the direction towards the right of the operator (back side in Figure 1) is described as the right.

[0015] Furthermore, the horizontal direction, which is perpendicular to the longitudinal direction A3, will be described as the aircraft width direction (the width direction of the aircraft 2). The direction from the center of the aircraft 2's width direction toward the right or left side will be described as the outward direction in the aircraft width direction. In other words, the outward direction in the aircraft width direction is the direction away from the center of the aircraft 2's width direction. The direction opposite to the outward direction in the aircraft width direction will be described as the inward direction in the aircraft width direction. In other words, the inward direction in the aircraft width direction is the direction approaching the center of the aircraft 2's width direction.

[0016] As shown in Figure 1, the running gear 3 is a crawler-type running gear that supports the machine body 2 so that it can move. In this embodiment, a crawler-type running gear 3 is used, but it is not limited to this, and a running gear of the wheel type or other type may also be used. A bulldozer device 7 is attached to the front of the running gear 3.

[0017] As shown in Figure 1, the machine body 2 has a swivel base plate 5 formed from a thick plate material that constitutes the bottom of the machine body 2. The swivel base plate 5 is supported on the traveling device 3 via a swivel bearing 8 so as to be able to swivel around a swivel axis X1, which is an axis that extends in the vertical direction. The swivel base plate 5 is driven to swivel around the swivel axis X1 by a swivel motor (hydraulic motor).

[0018] Furthermore, the machine body 2 has a support bracket 9 and a swing bracket 10 at its front that support the work device 4. The support bracket 9 is provided so as to protrude forward from the machine body 2 (see Figure 6). The swing bracket 10 is attached to the front of the support bracket 9 so as to be able to swing around a vertical axis (an axis that extends in the vertical direction).

[0019] As shown in Figure 1, the work device 4 includes a boom 11, an arm 12, and a work tool 13. In this embodiment, the work tool 13 is exemplified by a bucket. The base of the boom 11 is pivotally attached to the upper part of the swing bracket 10 so as to be rotatable around a horizontal axis (an axis extending in the direction of the machine width). A work light 110 is provided in the middle of the boom 11 in the longitudinal direction. In this embodiment, the work light 110 is mounted on the right side of the boom 11.

[0020] The arm 12 is pivotally attached to the tip of the boom 11 so as to be rotatable around a horizontal axis. The bucket 13 is mounted on the tip of the arm 12 so as to be able to perform scooping and dumping operations.

[0021] The swing bracket 10 is designed to swing by the extension and retraction of a swing cylinder (not shown).

[0022] As shown in Figure 1, a floor area 21 is provided on the upper side of the machine body 2 and in front of the driver's seat 6, where the operator places their feet. The floor area 21 is constructed, for example, by laying a floor mat on step plates that are positioned at intervals above the slewing base plate 5 and supported by the slewing base plate 5.

[0023] As shown in Figure 1, a weight 25 is positioned at the rear of the machine body 2 to balance the weight with the work device 4. A prime mover 91 is also mounted at the rear of the machine body 2. The work device 1 in this embodiment is a small backhoe with the driver's seat 6 positioned above the prime mover 91.

[0024] As shown in Figure 3, the prime mover 91 is located at the rear of the aircraft body 2 and midway along its width. A cooling fan 100 is attached to one side (left side) of the prime mover 91 in the width direction of the aircraft body. The cooling fan 100 is driven by the prime mover 91 and, in this embodiment, generates cooling air that flows from one side to the other (from left to right) in the width direction of the aircraft body.

[0025] Upstream of the cooling fan 100 in the direction of airflow (the direction in which the cooling air flows), to the left of the prime mover 91, are the radiator 92, oil cooler 93, and battery 94. The radiator 92 is a cooler that cools the coolant that cools the prime mover 91. The oil cooler 93 is a cooler that cools the return hydraulic fluid that returns from hydraulic actuators such as hydraulic cylinders and hydraulic motors. The battery 94 is a storage battery that supplies power to the electrical components equipped on the work machine 1.

[0026] As shown in Figure 3, a flywheel housing 199, which houses the flywheel, is attached to the other side (right side) of the engine 91 in the machine width direction. A hydraulic pump 95 is assembled to the flywheel housing 199. The hydraulic pump 95 is driven by the power of the engine 91 and discharges hydraulic fluid (pressurized oil) to drive hydraulic actuators such as hydraulic motors and hydraulic cylinders equipped on the work machine 1. The hydraulic pump 95 also discharges pilot pressure to operate hydraulic valves and pressurized oil for signaling. Above the flywheel housing 199, a muffler 200 is positioned to which exhaust gas from the engine 91 is guided.

[0027] As shown in Figure 3, the cooling fan 100, radiator 92, oil cooler 93, battery 94, flywheel housing 199, hydraulic pump 95, and muffler 200 are located in the engine room 91A which houses the prime mover 91.

[0028] The engine room 91A consists of a rotating base plate 5, weights 25, a machine body cover 107, a partition wall 150 (see Figure 6), a bonnet 101 (see Figure 4), and the like.

[0029] The cooling fan 100 draws outside air into the engine compartment 91A from the outside air intake port 89 of the bonnet 101. The outside air (cooling air) taken into the engine compartment 91A cools the oil cooler 93, radiator 92, and engine 91, and is then discharged from the outlet 88, etc.

[0030] As shown in Figures 1 and 2, the machine body 2 is equipped with an operating unit 18, which includes a driver's seat 6, a travel lever 16 located in front of the driver's seat 6, a console 17L located to the left of the driver's seat 6, and a console 17R located to the right of the driver's seat 6. The travel lever 16 is an operating member for operating the travel device 3. Consoles 17L and 17R are structures that integrate various functions.

[0031] As shown in Figure 2, the left console 17L includes a control lever 23L, a remote control valve (not shown), a console cover 22, an armrest 26L, an operation lock lever (unload lever) 30, and a frame mechanism that supports the remote control valve, console cover 22, armrest 26L, and operation lock lever 30.

[0032] The control lever 23L is located in front of and above the console 17L and can be tilted forward and backward, and left and right. The remote control valve is a pilot valve operated by the control lever 23L and is located below the control lever 23L.

[0033] The console cover 22 is a component that covers the remote control valve, frame mechanism, etc. The armrest 26L is a component on which the operator rests their elbow, etc., and is located behind the control lever 23L. The operation lock lever 30 is a lever that switches the hydraulic actuator mounted on the work machine 1 between an operable state and an operable state.

[0034] As shown in Figure 6, the console 17R on the right is attached to a support frame 142 erected on the aircraft body 2. The support frame 142 is erected on the slewing frame 14, which constitutes the skeleton of the aircraft body 2. The console 17R may also be directly attached to the components that make up the aircraft body 2. In other words, the console 17R (console bracket 33, described later) can be attached to the aircraft body 2 directly or indirectly.

[0035] As shown in Figure 6, the swivel frame 14 includes the swivel base plate 5, a pair of left and right longitudinal ribs 224L and 224R fixed on the swivel base plate 5, and a partition wall 150. The pair of longitudinal ribs 224L and 224R extend rearward from a support bracket 9 fixed to the front of the swivel base plate 5. The partition wall 150 is positioned midway along the pair of longitudinal ribs 224L and 224R in the front-rear direction and extends from one longitudinal rib 224L or 224R to the other.

[0036] The rear of the left longitudinal rib 224L is connected to the first bracket member 151L via a connecting plate 225. The rear of the right longitudinal rib 224R is connected to the second bracket member 151R. The first bracket member 151L and the second bracket member 151R are components that, together with the slewing base plate 5, constitute the slewing frame 14 (aircraft body 2).

[0037] As shown in Figures 2, 4, 5, 6, and 7, the right console 17R includes a control lever 23R, a remote control valve 40, an armrest 26R, a dozer lever 35, a console cover 34, a console bracket 33, communication equipment 38, equipment bracket 39, electrical components 36 (see Figure 10), a mounting stay 37, a mobile device holder 27, a pair of switches 28, an accelerator operating device 29, a starter 31, and a socket 32.

[0038] The control lever 23R is located in front of and above the console 17R and can be tilted forward and backward, and left and right. The remote control valve 40 is a pilot valve operated by the control lever 23R and is located below the control lever 23R.

[0039] Here, the control levers 23L and 23R are described as follows: By tilting the control levers 23L and 23R, the work device 4 and the machine body 2 are operated. Specifically, the control levers 23L and 23R perform operations such as swinging the boom 11, swinging the arm 12, scooping and dumping the bucket 13, and rotating the machine body 2. More specifically, the control lever 23L operates, for example, the bucket control valve that controls the bucket cylinder C4 that drives the bucket 13 and the slewing control valve that controls the slewing motor that rotates the machine body 2. The control lever 23R operates, for example, the boom control valve that controls the boom cylinder C2 that drives the boom 11 and the arm control valve that controls the arm cylinder C3 that drives the arm 12.

[0040] The armrest 26R is a component on which the operator rests their elbow or wrist. The armrest 26R is located behind the control lever 23R. The dozer lever 35 is a lever that operates the dozer device 7. The dozer device 7 is operated by tilting the dozer lever 35 forward or backward. The dozer lever 35 is located outward (to the right) in the width direction of the machine body from the armrest 26R.

[0041] The console cover 34 is molded from resin. The console cover 34 covers the console bracket 33, remote control valve 40, electrical components 36, mounting stay 37, communication equipment 38, equipment bracket 39, etc.

[0042] As shown in Figures 8, 9, 10, and 11, the console cover 34 has a first side wall 34a, a second side wall 34b, a front wall 34c, a rear wall 34d, and an upper wall 34e. The interior enclosed by these first side wall 34a, second side wall 34b, front wall 34c, rear wall 34d, and upper wall 34e is formed in a hollow shape. The lower surface of the console cover 34 is also open. In other words, the console cover 34 is formed to be open downwards.

[0043] As shown in Figures 3 and 4, the cover body 101D, which is located on the right side of the aircraft body 2 and constitutes part of the bonnet 101, has a notch 106 cut out from the middle to the rear of its upper surface in the front-rear direction. The console cover 34 is located above this notch 106. Therefore, the lower side of the console cover 34 is in communication with the interior of the cover body 101D (engine room 91A).

[0044] As shown in Figure 12, the first side wall portion 34a is located to the side (right side) of the driver's seat 6 in the width direction of the machine body. As shown in Figures 8 and 10, the first side wall portion 34a has an opening 51 formed midway in the front-rear direction and a cover 52 that can open and close the opening 51.

[0045] As shown in Figure 10, the second side wall portion 34b is provided with a gap between it and the first side wall portion 34a on the side (right side) in the width direction of the aircraft. In other words, as shown in Figure 12, the second side wall portion 34b is provided with a gap between it and the first side wall portion 34a on the side opposite to the driver's seat 6.

[0046] As shown in Figure 11, the front wall portion 34c connects the front part of the first side wall portion 34a and the front part of the second side wall portion 34b. The rear wall portion 34d connects the rear part of the first side wall portion 34a and the rear part of the second side wall portion 34b. As shown in Figures 8, 9, and 10, the upper wall portion 34e constitutes the upper part of the console cover 34. The rear portion 34f of the upper wall portion 34e is formed at a lower position than the middle and front portions in the front-rear direction. The rear portion of the upper wall portion 34e can be used as a place to put small items.

[0047] As shown in Figures 13, 14, and 15, the console bracket 33 includes a first side plate 33L, a second side plate (support plate) 33R, a mounting base 41, a front connecting plate 42F, a rear connecting plate 42R, an intermediate plate 44, and a mounting plate 43. The first side plate 33L is positioned outward (to the right) in the width direction of the driver's seat 6. The front portion 33La of the first side plate 33L is formed to be long in the vertical direction, and the rear portion 33Lb extends rearward from the lower part of the front portion 33La. The first side plate 33L and the second side plate 33R are spaced apart in the width direction of the aircraft. Specifically, the second side plate 33R is positioned outward (to the right) in the width direction of the first side plate 33L.

[0048] As shown in Figure 15, a support shaft 46 is provided protruding to the right from the front of the second side plate 33R. As shown in Figure 7, a support cylinder 50, provided at the lower end of the dozer lever 35, is rotatably supported on the support shaft 46 around an axis extending in the width direction of the machine body. One end of an operating cable 47 is connected to an arm 48 fixed to the support cylinder 50. The other end of the operating cable 47 is connected via an interlocking mechanism to a control valve that controls the hydraulic cylinder that drives the dozer device 7.

[0049] As shown in Figures 13, 14, and 15, the mounting base 41 is positioned on the front and upper right side of the first side plate 33L and is fixed to the left side of the first side plate 33L. The mounting base 41 is also positioned above the front of the second side plate 33R. The mounting base 41 has an upper wall 41a and a rear wall 41b. As shown in Figure 9, the upper part of the remote control valve 40 is attached to the upper wall 41a of the mounting base 41. A mounting stay 45 for attaching the armrest 26R is bolted to the back of the rear wall 41b.

[0050] As shown in Figures 9 and 14, the intermediate plate 44 is positioned below the rear wall 41b of the mounting base 41, with its upper part fixed to the lower end of the rear wall 41b. The intermediate plate 44 is also positioned between the rear end of the front part of the first side plate 33L and the second side plate 33R, connecting the first side plate 33L and the second side plate 33R. A sealing contact portion 44a is provided at the lower end of the intermediate plate 44.

[0051] As shown in Figure 15, the front connecting plate 42F is positioned between the lower front part of the first side plate 33L and the front part of the second side plate 33R, connecting the first side plate 33L and the second side plate 33R. As shown in Figure 13, the rear connecting plate 42R is positioned between the rear part of the first side plate 33L and the rear part of the second side plate 33R, connecting the first side plate 33L and the second side plate 33R. The mounting plate 43 is formed from a plate material that is long in the front-rear direction, positioned below the first side plate 33L with its plate surface facing up and down, and its right side is fixed to the lower end of the first side plate 33L.

[0052] As shown in Figures 6 and 13, the mounting plate 43 is superimposed on the upper surface of the upper side frame portion 145R, which is located on the upper right side of the support frame 142, and is attached to the upper side frame portion 145R by bolts or the like. In other words, the console bracket 33 is attached to the support frame 142 and to the aircraft body 2 via the support frame 142. The console bracket 33 may also be attached to a component of the aircraft body 2. That is, the console bracket 33 is attached to the aircraft body 2 directly or indirectly.

[0053] As shown in Figures 9, 10, and 11, the console bracket 33 is covered by the console cover 34. Specifically, the left side of the console bracket 33 is covered by the first side wall portion 34a of the console cover 34, the right side of the console bracket 33 is covered by the second side wall portion 34b, the front of the console bracket 33 is covered by the front wall portion 34c, the rear of the console bracket 33 is covered by the rear wall portion 34d, and the top of the console bracket 33 is covered by the top wall portion 34e.

[0054] The console cover 34 is attached to the console bracket 33 by screws or the like. Specifically, the rear part 34f of the upper wall portion 34e of the console cover 34 is attached to a mounting stay 53 (see Figure 13) provided at the rear of the console bracket 33, and the front wall portion 34c of the console cover 34 is attached to the front connecting plate 42F of the console bracket 33.

[0055] The communication device 38 is a Direct Communication Unit (DCU) that communicates data with external devices (not shown). The communication device 38 receives and sends data from an Information Processing Unit (IPU) 59, which is an information processing device described later. The communication device 38 also transmits data such as data received from the IPU 59 and location information to a server. The server is, for example, a server installed at the manufacturer (manufacturing company) that produces the work machine 1, or a server installed at a dealer (sales and maintenance company) that sells and maintains the work machine 1.

[0056] The communication device 38 is a waterproof device that houses an electronic circuit board, a communication antenna 49 (see Figure 16), and a positioning antenna (GPS antenna) within a resin case. The communication antenna 49 and the positioning antenna are mounted on the electronic circuit board. The communication antenna 49 is, for example, an LTE antenna (Long Term Evolution antenna). The communication antenna 49 is also an antenna that communicates with the server.

[0057] In the case of the above-mentioned communication device 38, since the communication antenna 49 is built into the communication device 38, it can maintain a state where communication is possible even when theft or other fraudulent activity (such as removing the communication device 38) is taking place, and can notify the designated reporting destination.

[0058] The positioning antenna receives satellite signals transmitted from positioning satellites. Based on the satellite signals received by the positioning antenna, the work machine 1 detects its own position (positioning information including latitude and longitude) using a positioning system. Specifically, the work machine 1 determines its position and bearing using the well-known GPS (Global Positioning System), an example of a Global Navigation Satellite System (GNSS) (for example, by RTK-GPS, which is suitable for positioning moving objects). That is, the work machine 1 communicates with a base station (reference station) installed at a known location, and the base station transmits positioning data (correction information) obtained by receiving radio waves from positioning satellites to the work machine 1. The work machine 1 detects its own position (latitude and longitude) based on the positioning data obtained by receiving radio waves from positioning satellites and the positioning data from the base station. The communication device 38 transmits and receives position information.

[0059] As shown in Figures 7, 9, 10, 11, and 15, the equipment bracket 39 is a bracket to which the communication device 38 is attached. The communication device 38 is attached to the console bracket 33 via the equipment bracket 39. The equipment bracket 39 and the communication device 38 are located inside the console cover 22. In other words, the communication device 38 is located inside the console 17R. By placing the communication device 38 inside the console 17R, theft of the communication device 38 can be deterred. It also improves the appearance of the work machine 1. Furthermore, by placing the communication device 38 inside the console 17R, there is no need to provide a dedicated cover for the communication device 38.

[0060] As shown in Figures 7, 9, 10, 11, and 15, the communication device 38 is located on the right side of the rear of the console bracket 33 (on the side opposite to the driver's seat 6). More specifically, the communication device 38 is located on the right side of the rear of the second side plate (support plate) 33R. Furthermore, the communication device 38 is located midway in the front-to-back direction relative to the console cover 34 (console 17R) (see Figure 9).

[0061] Furthermore, as shown in Figure 3, the communication equipment 38 is positioned above the hydraulic pump 95 and the muffler 200.

[0062] As shown in Figures 10 and 11, the communication device 38 is positioned closer to the second side wall 34b between the first side wall 34a and the second side wall 34b. The communication device 38 is positioned so that its front surface 38A faces outward in the width direction of the device and is facing the second side wall 34b. As shown in Figure 15, the communication device 38 has an indicator 54. The indicator 54 is located midway in the front-to-back direction at the bottom of the front surface 38A side of the communication device 38. The indicator 54 displays, for example, the operating status (communication status) of the communication device 38. The indicator 54 has three indicator lamps 54a. As shown in Figures 10, 11 and 19, the second side wall 34b is positioned so that the indicator 54 faces the console 17 R It has a viewing hole 55 that is visible from the outside.

[0063] The communication device 38, which has an indicator 54 on the front surface 38A of the device, is positioned so that the front surface 38A faces outward in the width direction of the machine and is facing the second side wall 34b, and a viewing hole 55 is formed in the second side wall 34b, so that the indicator 54 can be easily seen from the outside in the width direction of the work machine 1.

[0064] As shown in Figures 10 and 11, the second side plate (support plate) 33R of the console bracket 33 is positioned between the first side wall 34a and the communication equipment 38. The equipment bracket 39 is positioned between the second side plate 33R and the communication equipment 38 and is attached to the second side plate 33R. This allows the communication equipment 38 to be positioned closer to the second side wall 34b between the first side wall 34a and the second side wall 34b. Furthermore, when arranging the communication equipment 38 inside the console 17R, the second side wall 34b can be extended outward in the width direction of the device, making it easy to secure space for the communication equipment 38 inside the console 17R (console cover 34).

[0065] As shown in Figure 15, the equipment bracket 39 includes a mounting plate 56, a vertical member 57, and a mounting stay 58. The mounting plate 56 is made of a metal plate that is substantially rectangular in shape when viewed from the side. The mounting plate 56 is positioned on the rear side 38B of the communication equipment 38, which is opposite to the front side 38A of the equipment. The communication equipment 38 is attached to the four corners of the mounting plate 56 with screws or the like. The mounting plate 56 has a notch 60 formed through the mounting plate 56. As shown in Figure 16, the communication antenna 49 is positioned at a location corresponding to the notch 60, and care has been taken to ensure that the mounting plate 56 does not become an obstruction to radio waves.

[0066] The vertical member 57 is formed from channel steel and is positioned extending vertically on the left side of the mounting plate 56 with its opening facing to the right. The vertical member 57 is fixed to the left side of the mounting stay 58 by welding or the like.

[0067] The mounting bracket 58 is formed from a plate and has an upper wall 58a with its surface facing vertically, and a vertical wall 58b extending downward from the left end of the upper wall 58a. The upper wall 58a of the mounting bracket 58 is fixed to the lower end of the vertical member 57. The mounting bracket 58 is fixed to the second side plate 33R by bolts 61, with the vertical wall 58b overlapping the right side of the second side plate 33R midway in the vertical direction (see Figure 10).

[0068] As shown in Figure 16, the equipment bracket 39 is attached to the second side plate 33R, so that the communication antenna 49 is positioned above the second side plate 33R. In other words, the equipment bracket 39 is attached to the second side plate 33R such that the communication antenna 49 is positioned above the second side plate (support plate) 33R. By positioning the communication antenna 49 above the second side plate 33R, care is taken to ensure that the second side plate 33R does not become an obstruction to radio waves.

[0069] As shown in Figures 10 and 14, an electrical component 36 is positioned between the second side plate 33R and the first side wall portion 34a. In this embodiment, the electrical component 36 is a fuse box with a fuse installed inside. The electrical component 36 is attached to the mounting bracket 37.

[0070] As shown in Figure 18, a pair of mounting stays 37 are provided on the left side of the rear of the second side plate 33R. The mounting stay 37 has an upper plate portion 37a, a lower plate portion 37b, and a vertical plate portion 37c. The lower plate portion 37b is positioned below the upper plate portion 37a with a gap between them. The vertical plate portion 37c connects the right end of the upper plate portion 37a to the right end of the lower plate portion 37b. The lower part of the vertical plate portion 37c is superimposed on the left side of the second side plate 33R and fixed to the second side plate 33R. Therefore, the mounting stay 37 is fixed to the second side plate 33R in a manner that protrudes upward from the second side plate 33R.

[0071] As shown in Figure 10, the electrical component 36 has insertion parts 36a at its upper and lower ends, and is attached to the mounting bracket 37 such that the upper plate portion 37a and lower plate portion 37b are inserted into the insertion parts 36a. The electrical component 36 faces the opening 51 of the console cover 34, and by removing the cover 52, the electrical component 36 can be accessed from outside the console cover 34 (e.g., to replace a fuse).

[0072] As shown in Figures 16, 17, and 18, a notch 62 is formed in the mounting stay 37. The notch 62 extends from the right and front part of the upper plate part 37a to the upper and front part of the vertical plate part 37c. As shown in Figure 16, the notch 62 is located in the width direction of the aircraft body, corresponding to the communication antenna 49. In other words, the mounting stay 37 has a notch 62 formed by cutting out the part corresponding to the communication antenna 49. In this embodiment, the front communication antenna 49 is located in the position corresponding to the notch 62 of the front mounting stay 37.

[0073] Incidentally, when arranging the communication equipment 38, it is required that there be no radio wave obstructions within a predetermined distance from the communication antenna 49. By forming a notch 62 in the mounting bracket 37, which is formed by cutting out a portion corresponding to the communication antenna 49, it is possible to prevent the mounting bracket 37 from becoming a radio wave obstruction. In other words, the requirement that there be no radio wave obstructions within a predetermined distance from the communication antenna 49 can be achieved by the notch 62. For example, if the notch 62 is not formed in the mounting bracket 37, the communication equipment 38 must be placed a predetermined distance away from the mounting bracket 37. However, by forming the notch 62 in the mounting bracket 37, the communication equipment 38 can be brought closer to the mounting bracket, and the communication equipment 38 can be compactly arranged inside the console 17R (it is possible to suppress the need to widen the second side wall portion 34b more than necessary).

[0074] In this embodiment, there are no radio wave shielding objects at predetermined distances to the right, front, rear, and top and bottom of the communication device 38. Also, in this embodiment, only the front mounting bracket 37 requires a notch 62, but in order to unify the shape of the mounting brackets 37, the rear mounting bracket 37 is formed to be the same shape as the front mounting bracket 37.

[0075] As shown in Figures 8 and 12, the mobile device holder 27, the pair of switches 28, the accelerator operating device 29, and the socket 32 ​​are located on the upper part of the console cover 34.

[0076] First, let me explain these arrangements.

[0077] As shown in Figures 8 and 12, the mobile device holder 27 is located midway along the front-to-back direction of the console cover 34 (console 17R) and closer to the driver's seat 6 than the center of the console cover 34 in the width direction of the machine. Also, as shown in Figure 12, the mobile device holder 27 is located to the side (right side) of the seat 6A and in front of the backrest 6B.

[0078] As shown in Figure 12, the pair of switches 28 are positioned to the side of the driver's seat 6 (seat portion 6A) and in front of the backrest portion 6B. Furthermore, the pair of switches 28 are located on the opposite side of the driver's seat 6 from the center of the console cover 34 (console 17R) in the width direction of the aircraft. The pair of switches 28 are also positioned side-by-side, front to back. Additionally, the pair of switches 28 are located midway along the console cover 34 (console 17R) in the front-to-back direction. Finally, the pair of switches 28 are positioned on the outer (right) side of the mobile device holder portion 27 in the width direction of the aircraft.

[0079] As shown in Figure 12, the accelerator operating device 29 is provided between the mobile terminal holder 27 and the pair of switches 28. As shown in Figure 4, the starter 31 and socket 32 ​​are provided on the vertical wall 34g between the middle and rear portion 34f of the console cover 34. In this embodiment, the starter 31 is provided on the left side of the vertical wall 34g, and the socket 32 ​​is provided on the right side of the vertical wall 34g.

[0080] In Figure 8, reference numeral 64 denotes a remote control valve. 40 This is a hole to avoid interference with the upper part. Reference numeral 65 indicates an insertion hole for the mounting stay 45 to protrude from inside the console 17R. Reference numeral 66 indicates a guide hole for the dozer lever 35 to protrude from inside the console 17R. Reference numeral 67 indicates a mounting hole for mounting the accelerator operating device 29. Reference numeral 68 indicates a mounting part for mounting the starter 31. Reference numeral 69 indicates a mounting part for mounting the socket 32.

[0081] Next, the mobile device holder 27, the pair of switches 28, the accelerator operating device 29, and the socket 32 ​​will be described in detail.

[0082] The mobile device holder 27 is the part that holds a mobile device 73 such as a smartphone.

[0083] As shown in Figure 10, the mobile device holder portion 27 is formed by being recessed from top to bottom, and has an upper edge portion 27a that forms an upper end opening, as well as an internal space (mobile device housing portion) 70 for housing the mobile device 73. Therefore, the mobile device 73 can be inserted into the mobile device housing portion 70 (mobile device holder portion 27) from above. Furthermore, the mobile device holder portion 27 can hold the mobile device 73 so that the display screen 73a of the mobile device 73 faces towards the driver's seat 6.

[0084] As shown in Figures 20 and 21, the internal space (mobile device housing) 70 of the mobile device holder 27 is formed by a first wall 27b, a second wall 27c, a third wall 27d, a fourth wall 27e, a fifth wall 27f, and a sixth wall 27g. As shown in Figure 21, the first wall 27b is the wall that faces the opposite side of the display screen 73a of the mobile device 73 when the mobile device 73 is housed so that its display screen 73a faces the driver's seat 6. The first wall 27b forms the right side of the inner surface of the mobile device housing 70. As shown in Figure 21, the first wall 27b is formed in a sloping shape that moves away from the driver's seat 6 as it extends upward. This allows the mobile device 73 to be held in the mobile device holder 27 so that an operator seated in the driver's seat 6 can easily view the display screen 73a of the mobile device 73.

[0085] As shown in Figure 20, the second wall 27c is a wall portion extending to the left from the front end of the first wall 27b, forming the front part of the inner surface of the mobile device housing 70. The third wall 27d is a wall portion extending to the left from the rear end of the first wall 27b, forming the rear part of the inner surface of the mobile device housing 70. The fourth wall 27e is a wall portion extending to the rear from the left end of the second wall 27c, forming the front part of the left side of the inner surface of the mobile device housing 70. The fifth wall 27f is a wall portion extending forward from the left end of the third wall 27d, forming the rear part of the left side of the inner surface of the mobile device housing 70. A gap is formed between the rear end of the fourth wall 27e and the front end of the fifth wall 27f.

[0086] As shown in Figure 21, the sixth wall 27g is a wall portion that extends to the left from the lower end of the first wall 27b and constitutes the bottom portion that supports the lower end of the mobile terminal 73. In other words, the sixth wall 27g forms the bottom surface (lower surface) of the inner surface of the mobile terminal housing 70.

[0087] As shown in Figures 20 and 21, the mobile device holder 27 has a groove 74 on the driver's seat 6 side. The groove 74 is formed from the upper edge 27a to the bottom 27g and is open from the mobile device housing 70 (internal space of the mobile device holder 27) toward the driver's seat 6 side. The groove 74 is formed by the seventh wall 27h, the eighth wall 27i, and the ninth wall 27j. As shown in Figure 20, the seventh wall 27h extends to the left from the rear end of the fourth wall 27e and is connected to the first side wall 34a of the console cover 34. The eighth wall 27i extends to the left from the front end of the fifth wall 27f and is connected to the first side wall 34a of the console cover 34. As shown in Figure 21, the ninth wall 27j extends to the left from the left end of the sixth wall 27g and is connected to the first side wall 34a of the console cover 34. The ninth wall 27j is formed in a sloping shape that transitions downward as it moves inward in the width direction of the aircraft (towards the cockpit 6 side).

[0088] Because the mobile device holder 27 has a groove 74, foreign objects such as water and dirt that have entered the mobile device storage section 70 can be easily removed from the inside of the mobile device storage section 70 through the groove 74.

[0089] The pair of switches 28 are, for example, light switches. Specifically, one switch (the front switch) 28F is used to turn on and off the work light 7 attached to the boom 11. The other switch (the rear switch) 28R is used to turn on and off the rotating light 71 (see Figure 2) installed on the roof 19 of the canopy 15. Note that switch 28F may also be used to turn on and off the headlight 72 (see Figure 2) installed on the roof 19 of the canopy 15. Furthermore, there may be one switch 28 or three or more. In other words, at least one switch 28 is sufficient.

[0090] Switch 28 is not limited to, but for example, it can be formed by a seesaw switch (rocker switch). Pressing the front end allows for one operation of turning the light on or off, and pressing the rear end allows for the other operation of turning the light on or off.

[0091] As shown in Figure 12, the switch 28 has a rectangular shape in plan view and is arranged in a sloping manner, moving away from the driver's seat 6 (outward in the width direction of the machine) as it is viewed from the front in plan view.

[0092] As shown in Figures 8 and 10, the pair of switches 28 are located above the communication device 38.

[0093] By positioning the switch 28 in a sloping manner, which moves away from the driver's seat 6 as it is viewed from above, the operator can press the switch 28 without having to widen the angle of their arm or twist their wrist. In other words, the operator can press the switch in a natural position.

[0094] Furthermore, by positioning the switch 28 on the opposite side of the driver's seat 6 from the center of the console 17R in the aircraft width direction, the operator can operate the switch 28 with their arm at a suitable distance from their side, resulting in improved operability of the switch 28. Additionally, by positioning the switch 28 above the communication equipment 38, space for the switch 28 can be secured.

[0095] The accelerator control device 29 determines the rotational speed of the prime mover 91 by operating a rotational speed regulator (governor) that sets the rotational speed of the prime mover 91. More specifically, the accelerator control device 29 includes an accelerator dial 29A that is operated manually by an operator. The accelerator dial 29A is connected to, for example, a control device. The control device acquires the rotational speed indicated by the accelerator dial 29A and outputs a command signal to the rotational speed regulator to match the rotational speed of the prime mover 91 to the rotational speed indicated by the accelerator dial 29A.

[0096] The starter 31 is a device for starting the engine. The socket 32 ​​is a USB socket or a cigarette lighter socket, etc.

[0097] As shown in Figure 4, the IPU 59 is located at the rear of the lower part of the driver's seat 6. The IPU 59 is an "information processing device" that temporarily stores information about the work machine 1 and performs predetermined processing (e.g., compression processing). The IPU 59 is also connected via a harness to a communication port of an in-vehicle communication network (not shown) and a communication port of an on-board diagnostics (OBD) device. The in-vehicle communication network consists of a CAN (Controller Area Network) and FlexRay mounted on the work machine 1. The IPU 59 receives information about the work machine 1 from the communication network and the on-board diagnostics device. The IPU 59 is also connected to a communication device 38 via a harness 64 and transmits data to the communication device 38. The IPU 59 and the communication device 38 are also connected via a harness to a power supply port (not shown), and power is supplied from the power supply port.

[0098] As shown in Figures 22 and 23, the IPU 59 comprises an IPU body 75 and a case body 76 that houses the IPU body 75. The case body 76 comprises a mounting plate 76A to which the IPU body 75 is attached, and a cover body 76B that is attached to the mounting plate 76A so as to cover the IPU body 75.

[0099] The IPU 59 is attached to the mounting portion 77 of the LOPS 15. The mounting portion 77 has a base member 77A and a connecting portion 77B. The base member 77A is attached to the rear upper frame 147 (see Figure 6) provided at the rear of the upper part of the support frame 142. The connecting portion 77B connects the connection portion 78A of the LOPS 15 to the base member 77A. The connection portion 78A of the LOPS 15 is the part that connects the lower ends of the left rear support portion 78L and the right rear support portion 78R of the LOPS 15. A bracket member 79 is fixed to the rear surface of the case body 76 (see Figure 4), and the IPU 59 is attached to the LOPS 15 by attaching the bracket member 79 to the connecting portion 77B.

[0100] As shown in Figures 3 and 10, the work machine 1 is equipped with a heat shield 316 that shields the communication equipment 38 from heat from the prime mover 91 side (prime mover 91, muffler 200, hydraulic pump 95, etc.). The heat shield 316 covers the communication equipment 38 from below and shields the communication equipment 38 from heat such as cooling air (hot air), convective heat, and radiant heat from the prime mover 91 side.

[0101] The work machine 1 of this embodiment described above comprises a machine body 2, a driver's seat 6 mounted on the machine body 2, a console 17R located to the side of the driver's seat 6, and a communication device 38 located inside the console 17R.

[0102] By placing the communication device 38 inside the console 17R, theft of the communication device 38 can be deterred. Furthermore, the appearance of the work machine 1 can be improved.

[0103] Furthermore, the console 17R has a first side wall portion 34a located to the side of the driver's seat 6, and a second side wall portion 34b provided at a distance from the first side wall portion 34a on the side opposite to the driver's seat 6, and the communication equipment 38 is positioned between the first side wall portion 34a and the second side wall portion 34b, closer to the second side wall portion 34b.

[0104] When arranging the communication equipment 38 inside the console 17R, the second side wall portion 34b can be extended outward in the width direction of the aircraft, making it easy to secure space for arranging the communication equipment inside the console 17R.

[0105] Furthermore, the communication device 38 has an indicator 54 provided on the side facing the second side wall 34b, and the second side wall 34b has a viewing hole 55 that allows the indicator 54 to be seen from outside the console 17R.

[0106] With this configuration, the indicator 54 can be viewed from the outer side in the width direction of the work machine 1.

[0107] Furthermore, the work machine 1 is equipped with an equipment bracket 39 to which the communication equipment 38 is attached, and the console 17R has a console bracket 33 which is attached directly or indirectly to the machine body 2, the console bracket 33 has a support plate (second side plate 33R) which is positioned between the first side wall portion 34a and the communication equipment 38, and the equipment bracket 39 is positioned between the support plate 33R and the communication equipment 38 and is attached to the support plate 33R.

[0108] With this configuration, the communication equipment 38 can be positioned closer to the second side wall 34b between the first side wall 34a and the second side wall 34b.

[0109] Furthermore, the work machine 1 includes an electrical component 36 positioned between the support plate 33R and the first side wall portion 34a, and a mounting stay 37 to which the electrical component 36 is attached. The communication equipment 38 incorporates a communication antenna 49. The equipment bracket 39 is attached to the support plate 33R such that the communication antenna 49 is positioned above the support plate 33R. The mounting stay 37 is fixed to the support plate 33R so as to protrude upward from the support plate 33R and has a notch 62 formed by cutting out a portion corresponding to the communication antenna 49.

[0110] When arranging the communication equipment 38, it is required that there be no radio wave obstructions within a predetermined distance from the communication antenna 49. By attaching the equipment bracket 39 to the support plate 33R such that the communication antenna 49 is positioned above the support plate 33R, it is possible to prevent the support plate 33R from becoming a radio wave obstruction. Furthermore, by forming a notch 62 in the mounting stay 37, which is cut out to correspond to the communication antenna 49, it is possible to prevent the mounting stay 37 from becoming a radio wave obstruction. In addition, by forming a notch 62 in the mounting stay 37, the communication equipment 38 can be brought close to the mounting stay 37, and the communication equipment 38 can be compactly arranged inside the console 17R.

[0111] Furthermore, the console 17R is positioned to the side of the driver's seat 6 in the width direction of the aircraft and has a mobile terminal holder 27 capable of holding a mobile terminal 73 so that the display screen 73a of the mobile terminal 73 faces towards the driver's seat 6. The mobile terminal holder 27 is located closer to the driver's seat 6 than the center of the console 17R in the width direction of the aircraft.

[0112] With this configuration, the mobile terminal 73 can be placed near the operator and in a position where the operator can see the display screen 73a.

[0113] Furthermore, the mobile device holder portion 27 is formed by being recessed from top to bottom and has an upper edge portion 27a that forms an upper end opening, a bottom portion 27g that supports the lower end of the mobile device 73, and a groove portion 74 that extends from the upper edge portion 27a to the bottom portion 27g and is open from the internal space 70 of the mobile device holder portion 27 toward the driver's seat 6 side. With this configuration, foreign objects such as water and dirt that have entered the mobile device holder 27 can be easily removed from the inside of the mobile device holder 27 through the groove 74.

[0114] Furthermore, the mobile terminal holder 27 has a wall portion (first wall 27b) that faces the opposite side of the display screen 73a of the mobile terminal 73 when the mobile terminal 73 is housed with the display screen 73a facing the driver's seat 6, and the wall portion 27b is formed in an inclined shape that moves away from the driver's seat 6 as it goes upwards.

[0115] With this configuration, the mobile terminal 73 can be held in the mobile terminal holder 27 so that the operator seated in the driver's seat 6 can easily view the display screen 73a of the mobile terminal 73.

[0116] Furthermore, the console 17R has at least one switch 28 located on the upper part of the console 17R, the driver's seat 6 has a seat portion 6A where the operator sits and a backrest portion 6B where the operator leans their back, the switch 28 is located to the side of the driver's seat 6 and in front of the backrest portion 6B, and is provided in an inclined shape that moves away from the driver's seat 6 as it is viewed from the front in a plan view.

[0117] This configuration allows the operator to press switch 28 without having to open their arm at a large angle or twist their wrist. In other words, the operator can press switch 28 in a natural position.

[0118] Furthermore, the switch 28 is located on the opposite side of the driver's seat 6 from the center of the console 17R in the aircraft width direction, and is positioned above the communication equipment 38.

[0119] By positioning the switch 28 on the opposite side of the driver's seat 6 from the center of the console 17R in the aircraft width direction, the operator can operate the switch 28 with their arm at a comfortable distance from their side, resulting in improved operability of the switch 28. Furthermore, by positioning the switch 28 above the communication equipment 38, space for the switch 28 can be secured.

[0120] Furthermore, the work machine 1 comprises a prime mover 91 mounted on the machine body 2, a bonnet 101 covering the prime mover 91, and a support frame 142 erected on the machine body 2 inside the bonnet 101 to support the bonnet 101, and the console 17R is attached to the support frame 142.
