Detailed Description

Hereinafter, a hydraulic excavator is taken as an example of a typical example of a construction machine according to an embodiment of the present invention, and the description is given in detail with reference to the drawings.

First, fig. 1 to 5 show a first embodiment of the present invention. The first embodiment is characterized in that the power supply device is provided on the rear side of the storage tray, and the second bottom surface portion is formed as a bottom surface portion longer than the first bottom surface portion. The first bottom surface portion is disposed at a position forward of the second bottom surface portion.

In fig. 1, a hydraulic excavator 1 as a construction machine includes: a lower traveling body 2 capable of traveling automatically; an upper swing structure 3 supported by the lower traveling structure 2 so as to be swiveled and constituting a vehicle body together with the lower traveling structure 2; and a working device 4 which is provided in front of the upper swing structure 3 so as to be capable of performing a pitching operation, and which performs an excavation operation of earth and sand.

Here, a part of the traveling performance of hydraulic excavator 1 according to the present embodiment will be described. Hydraulic excavator 1 performs work on an inclined surface or a stepped portion, or travels on an inclined surface or a stepped portion. For this reason, the hydraulic excavator 1 has, for example, 70% of climbing ability with respect to the horizontal ground G. The climbing ability of 70% means that the maximum climbing angle α with respect to the horizontal ground G is about 35 degrees. The above-described climbing capability of 70% and the maximum climbing angle α of 35 degrees are values that are changed in accordance with special specifications, option settings, and the like, and illustrate general values of the hydraulic excavator 1.

The climbing ability is defined as "the maximum ability capable of climbing a flat hard soil slope without causing a leakage of the hydraulic excavator due to the ability of the travel control device, the angle of inclination of the engine, the angle of inclination of fuel, hydraulic oil, etc., and the restriction of mechanical safety, etc., in order to climb, descend, and stop the hydraulic excavator in a no-load state. However, the maximum capacity is set to be able to continuously climb a slope without being affected by the sliding of the hydraulic excavator with the road surface. "(refer to JIS Standard A8403-1). Then, the maximum climbing angle α is set according to the climbing ability of the vehicle body.

Further, hydraulic excavator 1 has rotatable upper swing body 3. Therefore, when the upper swing structure 3 is swung during a tilting operation, the front side (cab 7 side) of the upper swing structure 3 is positioned above or below, and the tilting direction changes.

In describing the arrangement relationship of the upper rotating body 3, the direction of the line of sight of an operator sitting on a driver's seat 10 described later is described as the front side, and the opposite side is described as the rear side. The upper rotating body 3 includes: a rotating frame 5 forming a support structure; a counterweight 6 provided at the rear of the revolving frame 5 to balance the weight of the working device 4; and a cab 7 provided in the front left portion of the revolving frame 5. Upper rotating body 3 is disposed at a position where counterweight 6 formed in an arc shape is close to the center of rotation. As a result, hydraulic excavator 1 is configured as a rear ultra-small rotary hydraulic excavator in which the outer peripheral surface of counterweight 6 is housed within 120% of the vehicle width dimension of lower traveling structure 2 when upper rotating body 3 rotates on lower traveling structure 2.

The cab 7 is formed in a box shape by a rectangular floor member 8 (see fig. 2) and a cab box 9 provided above the floor member 8. The floor member 8 of the cab 7 is formed as a rectangular plate body that is long in the front-rear direction. A driver seat base 8A is provided on the rear side of the floor member 8. In the operation room in the cab 7, an operator's seat 10, a travel operation lever, a pedal 14, a left console device 15, a right console device 19, and the like, which will be described later, are provided.

The cab box 9 is formed in a box shape by a front panel 9A, a rear panel 9B, a left panel 9C, a right panel (not shown), and a top panel 9D. The left panel 9C is provided with a door 9E that opens and closes when an operator enters and exits an operation room in the cab 7.

The operator's seat 10 is provided in a vehicle body, that is, in an operator's cab 7 constituting the upper swing structure 3. The driver seat 10 is provided on a driver seat base 8A of the floor member 8. The operator is seated in the driver's seat 10. A rear cover 11 is provided behind the driver seat 10 so as to cover the rear panel 9B. The rear cover 11 covers electrical components (not shown) and the like. The rear cover 11 is provided with a power supply device 12, which will be described later, on the upper right side, which is the rear side of the right console device 19.

The power supply device 12 is provided on the rear side of the right console device 19, that is, on the rear side of a storage tray 23 described later. The power supply device 12 is configured by, for example, a USB port, an accessory socket, an igniter socket, and the like. As an example of a method of using the power supply device 12, a charging cable 26 connected to the communication terminal 25 when charging the communication terminal 25 is connected.

The right front console 13 extends upward from the right front side of the floor member 8 along the right panel of the cab box 9. The front right console 13 constitutes a console. The right front console 13 is positioned at the right front of the driver seat 10, and includes meters (neither shown) such as a monitor and a switch.

The left and right travel levers and pedals 14 are provided at front positions of the floor member 8 in front of the driver's seat 10. The left and right travel operation levers and pedals 14 can be tilted in the front-rear direction to cause the lower traveling structure 2 to travel.

The left console device 15 is located on the left side of the driver's seat 10 and attached to the seat base 8A of the floor member 8. The left console device 15 is configured to include a left console box 16 extending in the front-rear direction and an operation lever 17 provided at the front of the left console box 16. The operation lever 17 operates the working device 4 and the like. Further, the left console device 15 is provided with an armrest 18, and the armrest 18 is positioned above the rear portion of the left console box 16 and carries the left arm of the operator.

The right console device 19 is located around the driver's seat 10, i.e., on the right side of the driver's seat 10, and is provided on the upper rotating body 3 constituting the vehicle body. The right console device 19 includes a right console box 20, an operation lever 21, an armrest 22, and a storage tray 23, which will be described later.

The right console box 20 constitutes a console. The right console box 20 is provided as a box-like body extending in the front-rear direction on the right side of the driver seat 10. The right console box 20 includes: a rectangular upper surface portion 20A long in the front-rear direction, a front surface portion 20B extending downward from the front portion of the upper surface portion 20A, a rear surface portion 20C extending downward from the rear portion of the upper surface portion 20A, a left surface portion 20D extending downward from the left portion of the upper surface portion 20A, and a right surface portion 20E extending downward from the right portion of the upper surface portion 20A.

A front side portion of the upper face portion 20A of the right console box 20 becomes a lever mounting portion 20A1 for mounting the operation lever 21. Further, an operation panel 20F is provided on the rear side of the upper surface portion 20A of the right console box 20, and the operation panel 20F is located on the right side away from the driver's seat 10 and includes various switches. Further, a storage tray 23 described later is provided on the upper surface portion 20A on the left side (driver seat 10 side) of the operation panel 20F.

Here, as shown in fig. 5, the upper surface portion 20A of the right console box 20 is a horizontal surface H parallel to the horizontal floor surface G. It is considered that this horizontal plane H slightly inclines with respect to the ground G under the conditions of tolerance related to processing and assembly of each part, posture of the working device 4, weight of the operator on board, aged deterioration of mounting members (not shown) supporting the cab 7, and the like. That is, the upper surface portion 20A is designed to be parallel to the ground G and close to parallel. The upper surface portion 20A of the right console box 20 may be an inclined surface with a right side or a front side being higher, for example, so that an operator seated in the driver seat 10 can easily operate the operation panel 20F and the like.

The operating lever 21 is provided on a lever mounting portion 20a1 located at the front of the right console box 20. The operation lever 21 operates the working device 4 and the like in the same manner as the left-side operation lever 17. The armrest 22 is disposed above the rear portion of the right console box 20. The right arm of the operator is placed on the armrest 22.

Next, the structure of the storage tray 23, which is a characteristic portion of the present embodiment, will be described in detail with reference to fig. 3 to 5. In addition, as an article stored in the storage tray 23, a thin plate-shaped communication terminal 25 (smartphone) having a rectangular shape is exemplified.

As shown in fig. 3 and 4, the storage tray 23 is provided as a recess opened upward in the upper surface portion 20A of the right console box 20 constituting the right console device 19. A rectangular thin plate-like article, for example, a communication terminal 25 such as a smartphone is stored in the storage tray 23. The storage tray 23 can store rectangular thin plate-like articles such as notepads and cigarettes in addition to the communication terminal 25.

The storage tray 23 has a rectangular shape long in the front-rear direction and short in the left-right direction, that is, an opening 24 having four sides. The storage tray 23 extends downward from the left and right sides of the opening 24, and includes a left side surface 23A and a right side surface 23B facing each other, a first bottom surface 23C located between the left side surface 23A and the right side surface 23B and extending obliquely downward from the front of the opening 24 to the rear, and a second bottom surface 23D located between the left side surface 23A and the right side surface 23B and extending obliquely downward from the rear of the opening 24 to the front.

A joint portion where the first bottom surface portion 23C and the second bottom surface portion 23D of the housing tray 23 are joined to each other becomes the deepest portion 23E of the recess. In other words, the storage tray 23 is formed with a bottomed hole having a triangular groove shape, and the apex of the triangle is the deepest portion 23E. The first bottom surface portion 23C and the second bottom surface portion 23D are arranged at right angles at the deepest portion 23E. Thus, the storage tray 23 (the side surfaces 23A and 23B) forms a right triangle.

Here, in the configuration in which the first bottom surface portion 23C and the second bottom surface portion 23D are arranged at right angles in the deepest portion 23E, the bottom surface portions 23C and 23D can be brought into surface contact with the two adjacent surfaces (2 sides), that is, the long side 25A and the short side 25B, of the communication terminal 25 to be housed.

The second bottom surface portion 23D is formed as a bottom surface portion longer than the first bottom surface portion 23C. In addition, the first bottom surface portion 23C is disposed in front of the second bottom surface portion 23D. That is, the long second bottom surface portion 23D is disposed at a position rearward of the short first bottom surface portion 23C. The long second bottom surface portion 23D is inclined at an angle β 1 with respect to the horizontal plane H. The angle β 1 of the second bottom surface portion 23D is set to 35 degrees or more and less than 90 degrees (35 degrees β 1 < 90 degrees), which is the maximum climbing angle α determined according to 70% of the climbing ability of the hydraulic excavator 1. Preferably, the angle β 1 of the second bottom surface portion 23D is set to 35 degrees or more and 60 degrees or less (35 degrees in the present embodiment). Thus, even when the front side of upper rotating body 3 is inclined up to 35 degrees at the maximum in the direction in which the front side becomes higher, second bottom surface portion 23D can maintain the inclination so as to become higher in the horizontal state or in the opening 24 side opposite to deepest portion 23E.

On the other hand, the first bottom surface portion 23C shorter than the second bottom surface portion 23D is inclined at an angle γ 1 with respect to the horizontal plane H. The angle γ 1 of the first bottom surface portion 23C is set to be 35 degrees or more and less than 90 degrees (35 degrees ≦ γ 1 < 90 degrees), which is the maximum climbing angle α, similarly to the angle β 1 of the second bottom surface portion 23D. The angle γ 1 of the first bottom surface portion 23C is preferably set to 35 degrees or more and 60 degrees or less (55 degrees in the present embodiment). Thus, even when the front side of upper rotating body 3 is inclined downward up to 35 degrees at maximum, first bottom surface portion 23C can maintain the inclination so that it is horizontal or the side of opening 24 opposite to deepest portion 23E is higher.

Since the first bottom surface portion 23C and the second bottom surface portion 23D set at such angles are inclined so as to be horizontal or to be higher on the opening 24 side even when the hydraulic excavator 1 is inclined to the maximum climbing angle α, the communication terminal 25 housed therein can be prevented from slipping out to the opening 24 side. On the other hand, if angle γ 1 of first bottom surface portion 23C and angle β 1 of second bottom surface portion 23D are not sufficient to reach 35 degrees of maximum climbing angle α of hydraulic excavator 1, when hydraulic excavator 1 performs work while being inclined at 35 degrees, opening 24 side becomes low, and communication terminal 25 slides down.

Further, since the communication terminal 25 of the first bottom surface portion 23C and the second bottom surface portion 23D has a rectangular shape, the first bottom surface portion 23C and the second bottom surface portion 23D are arranged at an angle of 90 degrees so that both the first bottom surface portion 23C and the second bottom surface portion 23D are in surface contact with the communication terminal 25. Thus, when the angle γ 1 of the first bottom surface portion 23C and the angle β 1 of the second bottom surface portion 23D are added, 90 degrees is obtained (γ 1+ β 1 is 90 degrees).

Of the first bottom surface portion 23C and the second bottom surface portion 23D, the long second bottom surface portion 23D is disposed at a position rearward of the short first bottom surface portion 23C. Thus, the inclination angle of the second bottom surface portion 23D located on the rear side where the power supply device 12 is provided can be made smaller than the inclination angle of the first bottom surface portion 23C. That is, as shown in fig. 4 and 5, the storage tray 23 can be stably stored in a state where the rectangular communication terminal 25 is laid down (the longitudinal direction is a lateral direction). Furthermore, since the communication terminal 25 lying down can have the insertion port (not shown) of the charging cable 26 directed to the rear side on the side of the power supply device 12, the communication terminal 25 can be easily connected to the power supply device 12 using the charging cable 26.

The communication terminal 25 is, for example, a smartphone. The communication terminal 25 is formed as a rectangular thin plate-like article. Specifically, the periphery (circumferential surface) of the communication terminal 25 includes two parallel long sides 25A and two parallel short sides 25B connecting the ends of the long sides 25A. In addition, the communication terminal 25 is provided with an insertion port (not shown) formed of a USB port or the like in one of the short sides 25B. A charging cable 26 and the like can be connected to the inlet.

The hydraulic excavator 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described below.

An operator who opens a door 9E of the cab box 9 and enters the cab 7 sits on the operator's seat 10. An operator sitting on the operator's seat 10 can cause the lower traveling structure 2 to travel by operating the travel operation lever and the pedal 14. Further, by operating the operating lever 17 of the left console device 15 and the operating lever 21 of the right console device 19, the working device 4 and the like can be operated to perform the excavation work of the earth and sand.

At the work site, communication is performed using the communication terminal 25 for confirmation of work, report of work status, and the like. At this time, the communication terminal 25 is accommodated in the accommodation tray 23 of the right console box 20 provided in the right console device 19. This allows the operator to easily use the communication terminal 25 by taking it out of the storage tray 23. After use, the communication terminal 25 can be stored in the storage tray 23 by inserting the communication terminal 25 into the storage tray 23 through the opening 24.

Here, the hydraulic excavator 1 may perform work in a state where the inclined surface or the like is inclined. At this time, hydraulic excavator 1 is inclined by 35 degrees at maximum (35 degrees at maximum inclination angle α) with respect to horizontal ground G. In this way, when the hydraulic excavator 1 is tilted to the maximum climbing angle α, it is considered that the communication terminal 25 housed in the housing tray 23 slides down. In particular, in the hydraulic excavator 1, the tilt direction of the cab 7 is different due to the rotation of the upper swing structure 3. That is, the housing tray 23 housing the communication terminal 25 is also largely inclined to the front side or the rear side.

However, in the present embodiment, the storage tray 23, which is open at the top and is configured by the recessed portion provided in the right console box 20, is formed by the pair of left and right side surfaces 23A and 23B facing each other, and the first bottom surface 23C and the second bottom surface 23D, which are provided between the pair of left and right side surfaces 23A and 23B obliquely with respect to the horizontal plane H and have the deepest portion 23E of the recessed portion as the joint portion therebetween. In addition, the angle γ 1 at which the first bottom surface portion 23C is inclined with respect to the horizontal plane H and the angle β 1 at which the second bottom surface portion 23D is inclined with respect to the horizontal plane H are set to 35 degrees or more and less than 90 degrees, which is the maximum climbing angle α determined according to the climbing ability of the vehicle body, that is, the lower traveling body 2.

Therefore, when the upper rotating body 3 is inclined forward and downward to the maximum climbing angle α (35 degrees), the first bottom surface portion 23C can maintain a horizontal state or an angle at which the opening 24 side becomes high with respect to the horizontal plane H (about 20 degrees in the embodiment). On the other hand, when the upper rotating body 3 is tilted forward and upward to the maximum climbing angle α (35 degrees), the second bottom surface portion 23D can be maintained in a horizontal state or in an angle at which the opening 24 side becomes higher with respect to the horizontal plane H (in the embodiment, in a horizontal state).

As a result, even when the hydraulic excavator 1 (upper swing structure 3) performs work on an inclined ground, the storage tray 23 can prevent the stored communication terminal 25 from sliding and falling.

The bottom of the storage tray 23 is formed by two surfaces including the first bottom surface portion 23C and the second bottom surface portion 23D. Therefore, either the long side 25A or the short side 25B of the communication terminal 25 can be brought into surface contact with the first bottom surface portion 23C or the second bottom surface portion 23D. In particular, in the present embodiment, the first bottom surface portion 23C and the second bottom surface portion 23D are arranged at right angles at the position of the deepest portion 23E. Therefore, the housing tray 23 can bring the long side 25A and the short side 25B of the communication terminal 25 into surface contact with the corresponding first bottom surface portion 23C and second bottom surface portion 23D. This can increase the frictional resistance of the communication terminal 25 against the housing tray 23, and also prevent the communication terminal 25 from flying out of the housing tray 23 and falling.

Both the first bottom surface portion 23C and the second bottom surface portion 23D are set to be 35 degrees or more with respect to the horizontal plane H. Therefore, even when the tilt direction (front-down, front-up, etc.) of the cab 7 is different, the communication terminal 25 can be stably held by either the first bottom surface 23C or the second bottom surface 23D by the rotation of the upper swing body 3.

Further, a left console box 16 having a front portion extending in the front-rear direction and provided with an operation lever 17 and a right console box 20 having an operation lever 21 are provided on both left and right sides of the driver's seat 10. The console is at least one of the left console box 16 and the right console box 20, and in the present embodiment, is the right console box 20 of the right console device 19. That is, the storage tray 23 can be provided in the right console box 20 to store the communication terminal 25.

The power supply device 12 is provided on the rear side of the storage tray 23. The second bottom surface portion 23D is formed as a bottom surface portion longer than the first bottom surface portion 23C. The first bottom surface portion 23C is disposed in front of the second bottom surface portion 23D. Thus, the storage tray 23 can be stably stored in a state in which the rectangular communication terminal 25 is oriented to the rear side of the power supply device 12. In this state, the communication terminal 25 can be easily connected to the power supply device 12 using the charging cable 26.

Next, fig. 6 and 7 show a second embodiment of the present invention. The present embodiment is characterized in that the power supply device is provided on the front side of the storage tray, the first bottom surface portion is formed as a bottom surface portion longer than the second bottom surface portion, and the first bottom surface portion is disposed in front of the second bottom surface portion. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

In fig. 6, the right console box 31 according to the second embodiment includes an upper surface portion 31A having a lever attachment portion 31A1 at the front, a front surface portion 31B, a rear surface portion 31C, a left surface portion 31D, and a right surface portion 31E, as in the right console box 20 according to the first embodiment. Further, an operation panel 31F and a storage tray 34 described later are provided on the right side of the upper surface portion 31A. However, the right console box 31 according to the second embodiment is different from the right console box 20 according to the first embodiment in that a power supply device 32 described later is provided.

The power supply device 32 is located on the front side of the storage tray 34 and is provided on the upper surface portion 31A of the right console box 31. Specifically, the power supply device 32 is positioned on the right side of the upper surface portion 31A, and is therefore arranged in parallel in the front portion of the operation panel 31F. The power supply device 32 is constituted by a USB port, for example. For example, when the communication terminal 25 is charged, the charging cable 33 connected to the communication terminal 25 is connected to the power supply device 32.

The storage tray 34 according to the second embodiment is provided as a recess opened to form an opening 35 at the upper side in the left position of the upper surface portion 31A of the right console box 31, similarly to the storage tray 23 according to the first embodiment. The storage tray 34 includes a left side surface 34A, a right side surface 34B, a first bottom surface 34C, and a second bottom surface 34D. Further, a joint portion where the first bottom surface portion 34C and the second bottom surface portion 34D are joined to each other becomes the deepest portion 34E of the recess. The first bottom surface portion 34C and the second bottom surface portion 34D are arranged at right angles at the deepest portion 34E. However, the storage tray 34 according to the second embodiment is different from the storage tray 23 according to the first embodiment in that the first bottom surface portion 34C is formed longer than the second bottom surface portion 34D.

Specifically, the short first bottom surface portion 34C is inclined at an angle γ 2 with respect to the horizontal plane H. The angle γ 2 of the first bottom surface portion 34C is set to 35 degrees or more and less than 90 degrees (35 degrees ≦ γ 2 < 90 degrees), which is the maximum climbing angle α determined according to the climbing ability of the hydraulic excavator 1. The angle γ 2 of the first bottom surface portion 34C is preferably set to 35 degrees or more and 60 degrees or less (35 degrees in the present embodiment). Thus, even when the front side of the upper rotating body 3 is inclined up to 35 degrees at maximum, the first bottom surface portion 34C can maintain the inclination in a horizontal state or in a state where the opening 35 side is high.

On the other hand, the long second bottom surface portion 34D is inclined at an angle β 2 with respect to the horizontal plane H. The angle β 2 of the second bottom surface portion 34D is set to be 35 degrees or more and less than 90 degrees (35 degrees ≦ β 2 < 90 degrees), which is the maximum slope angle α, similarly to the angle γ 2 of the first bottom surface portion 34C. Preferably, the angle β 2 of the second bottom surface portion 34D is set to 35 degrees or more and 60 degrees or less (55 degrees in the present embodiment). Thus, even when the front side of upper rotating body 3 is inclined downward up to 35 degrees at maximum, second bottom surface portion 34D can maintain the inclination in a horizontal state or in a state where the opening 35 side is high.

Of the first bottom surface portion 34C and the second bottom surface portion 34D set at such angles, the long first bottom surface portion 34C is disposed at a position forward of the short second bottom surface portion 34D. Thus, the inclination of the first bottom surface portion 34C on the front side where the power supply device 32 is provided can be made smaller than the inclination of the second bottom surface portion 34D. That is, the housing tray 34 can be stably housed in a state where the rectangular communication terminal 25 is laid down (the longitudinal direction is horizontal). The communication terminal 25 lying down can direct an insertion port (not shown) of the charging cable 33 toward the front side of the power supply device 32. This allows the communication terminal 25 to be easily connected to the power supply device 32 using the charging cable 33.

In this way, also in the second embodiment configured as above, the same effects as those in the first embodiment can be obtained. In particular, according to the second embodiment, the power supply device 32 provided on the right console box 31 and the communication terminal 25 can be simply connected at a short distance using the charging cable 33.

In the first embodiment, the case where the storage tray 23 is provided in the right console box 20 of the right console device 19 is exemplified. However, the present invention is not limited to this, and for example, a configuration may be adopted in which a storage tray is provided in the left console box of the left console device. In addition, a structure in which a storage tray is provided on the right front console may be adopted. These configurations can be similarly applied to the second embodiment.

In the first embodiment, the first bottom surface portion 23C is set to have an angle γ 1 of 55 degrees with respect to the horizontal plane H, and the second bottom surface portion 23D is set to have an angle β 1 of 35 degrees with respect to the horizontal plane H, and the angles are different from each other. However, the present invention is not limited to this, and the angle γ 1 of the first bottom surface portion 23C with respect to the horizontal plane H may be set to 45 degrees, and the angle β 1 of the second bottom surface portion 23D with respect to the horizontal plane H may be set to 45 degrees, so that both angles are the same. This structure can be similarly applied to the second embodiment.

In each embodiment, the hydraulic excavator 1 is described as an example of a construction machine. However, the present invention is not limited to this, and can be widely applied to other construction machines such as a hydraulic crane and a wheel loader.
