Description

[Technical field]

[0001] The present invention relates to a construction machine. [Background technology]

[0002] In construction machines such as hydraulic excavators, a console box is provided around the driver's seat where the operator sits. The console box mainly contains operation levers, operation switches, and instruments. This console box often includes a storage case with an open top for storing items such as a mobile terminal (e.g., a smartphone).

[0003] Patent Document 1 discloses a construction machine having a driver's seat provided on a vehicle body, a console provided around the driver's seat, and a storage tray that is open at the top and has a recess provided in the console. The storage tray is formed by a pair of side parts facing each other, and a first bottom part and a second bottom part that are provided between the pair of side parts and inclined with respect to the horizontal plane, and whose joint with each other forms the deepest part of the recess. The angle of inclination of the first bottom part and the second bottom part with respect to the horizontal plane is set to be equal to or greater than the maximum climbing angle determined from the climbing ability of the vehicle body and less than 90 degrees.

[0004] [Patent Document 1] Patent Publication No. 2021-37892 Summary of the Invention [Problem to be solved by the invention]

[0005] Construction machines such as mini excavators often perform excavation work or travel on uneven, bumpy ground, which can cause large vibrations in the upper rotating body. In the construction machine disclosed in Patent Document 1, the storage case can hold items even if the vehicle body is tilted below the maximum climbing angle, but if large vibrations occur during work or travel, the items may float up from the storage case and fall out of the storage case. In this case, if the construction machine is not provided with a cab box, the items may be thrown out of the machine.

[0006] In view of the above circumstances, an object of the present invention is to enable a storage case provided in a console box around the driver's seat to stably hold items even when large vibrations occur in a construction machine. [Means for solving the problem]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the embodiments, components with the same reference numerals have the same components in each embodiment unless otherwise specified, and the description thereof will be omitted.

[0011] In this embodiment, the direction of the line of sight of the operator seated in the driver's seat 8 is defined as "forward", and the opposite direction is defined as "rear". The direction toward the right hand side of the operator seated in the driver's seat 8 and perpendicular to the front-to-rear direction is defined as "right", and the opposite direction is defined as "left". The direction toward the top of the head of the operator seated in the driver's seat 8 and perpendicular to the front-to-rear and left-to-right directions is defined as "upward", and the opposite direction is defined as "downward".

[0012] Fig. 1 is a side view of a construction machine 100. Fig. 2 is a perspective view of a cab box 7.

[0013] The construction machine 100 is a self-propelled construction machine in which a console box 10 is provided around a driver's seat 8 where an operator sits. The construction machine 100 may be, for example, a hydraulic excavator, a wheel loader, a crane, or the like. In this embodiment, a hydraulic excavator will be taken as an example of the construction machine 100 to be described.

[0014] The construction machine 100 is composed of a self-propelled lower traveling body 3, an upper rotating body 1 rotatably supported on the lower traveling body 3, and a front working mechanism 2 rotatably supported on the front part of the upper rotating body 1 for performing excavation work and the like. The construction machine 100 may be a rear ultra-tight swing type hydraulic excavator in which, when the upper rotating body 1 swings on the lower traveling body 3, the outer peripheral surface of the counterweight 4 fits within 120% of the vehicle width dimension of the lower traveling body 3.

[0015] The construction machine 100 works on and travels over inclined surfaces and steps. The construction machine 100 has, for example, a 70% climbing ability on a level ground surface. A 70% climbing ability means that the maximum climbing angle on a level ground surface is about 35 degrees. Note that the 70% climbing ability and the maximum climbing angle of 35 degrees are examples of general values ​​for the construction machine 100, and the values ​​may vary depending on special specifications, option settings, etc.

[0016] Climbing ability is defined as "the maximum climbing ability of an unloaded hydraulic excavator when ascending, descending and stopping a flat, hard soil slope, taking into account the capacity of the travel control device, the engine tilt operating angle, the tilt angle at which fuel / hydraulic oil leakage does not occur, and machine safety. However, this is the maximum continuous climbing ability assuming that there is no effect from slippage between the hydraulic excavator and the road surface." (JIS standard A8403-1). The maximum climbing angle is determined in advance by the climbing ability of the construction machine 100.

[0017] The upper rotating body 1 includes a rotating frame 1a that forms a support structure, a counterweight 4 that is provided at the rear of the rotating frame 1a to balance the weight with the front working implement 2, and a cab 5 that is provided at the front left part of the rotating frame 1a.

[0018] The cab 5 is formed in a box shape by a floor panel 6 supported on the upper part of the revolving frame 1a and a cab box 7 provided on the floor panel 6.

[0019] The cab box 7 is formed into a box shape by a roof panel 7a that forms the upper surface of the cab box 7, a front panel 7b that forms the front surface of the cab box 7, a pair of side panels 7c that form a pair of side surfaces of the cab box 7, and a rear panel (not shown) that forms the rear surface of the cab box 7.

The front operating lever 17 is an operating lever for operating the front working mechanism 2 for performing excavation work, loading work, and the like. A wrist rest 18 is provided behind the front operating lever 17 of the left console box 10. The wrist rest 18 is also called a palm rest or an arm rest.

[0026] A front operation lever 17 is provided in front of the right console box 10. A blade operation lever 11 is provided in front of the right console box 10 and to the right of the front operation lever 17. The blade operation lever 11 is an operation lever that is disposed in front of the lower traveling body 3 and operates a blade (not shown) that performs ground leveling work and the like.

[0027] The right console box 10 includes, in addition to the installation portions of the operation levers 11, 17, a first switch box 13 and a second switch box 14. The first switch box 13 and the second switch box 14 are mainly provided with operation switches 21a to 24.

[0028] The first switch box 13 is provided in the right console box 10, rear of the installation portion of the operating levers 11, 17. The second switch box 14 is provided in the right console box 10, to the right of the first switch box 13. A cup holder 15 and a grease gun holder 16 are provided behind the second switch box 14 in the right console box 10.

[0029] A traveling speed changeover switch 21a, a traveling alarm switch 21b, and a work light switch 21c are provided in the front of the first switch box 13.

[0030] A monitor 20 is provided to the right of the first switch box 13, behind the operation switches 21a-21c. The monitor 20 displays the operating status of the construction machine 100. An engine control lever 19 is provided to the left of the first switch box 13, behind the operation switches 21a-21c. The engine control lever 19 is an operating lever that starts the engine, which is the power source.

[0031] A power port 24, a wiper switch 23, and a heater control switch 22 are provided on the right side of the second switch box 14. The power port 24 is, for example, a USB port, an accessory socket, or a cigarette lighter socket. The wiper switch 23 is an operation switch for operating a wiper (not shown) provided on the front panel 7b of the cab box 7, etc. The heater control switch 22 is an operation switch for controlling the temperature of the heater 12.

[0032] A storage case 30 is provided on the left side of the second switch box 14. The storage case 30 is recessed relative to the upper surface 14a of the second switch box 14, i.e., the upper surface of the console box 10, and is open at the top. The items stored in the storage case 30 are not particularly limited, and may be, for example, a mobile terminal M such as a smartphone or a tablet PC, a notebook, stationery, or cigarettes. In this embodiment, a thin plate-shaped item, particularly a mobile terminal M, will be described as an example of the item stored in the storage case 30.

[0033] The storage case 30 is disposed at a position farther from the driver's seat 8 in the left-right direction than the operation levers 9, 11, 17, 19 and the operation switches 21a-24. This makes it possible for the storage case 30 to prevent objects stored in the storage case 30 from interfering with the operator's hands when operating the operation levers 9, 11, 17, 19 or the operation switches 21a-24. Therefore, the storage case 30 makes it possible to prevent objects stored in the storage case 30 from getting in the way and interfering with the operation of the operation levers 9, 11, 17, 19 and the operation switches 21a-24.

[0034] The storage case 30 is disposed rearward of the front operating lever 17, which is an operating lever for the front working mechanism 2, and the blade operating lever 11. This makes it possible for the storage case 30 to prevent interference between the front operating lever 17 or the blade operating lever 11 and the operator's hand when the operator stores or removes items in the storage case 30 (hereinafter also referred to as "when storing or removing items"). Therefore, the storage case 30 makes it possible to prevent the front operating lever 17 or the blade operating lever 11 from being operated by mistake when storing or removing items, thereby compromising the safety of the construction machine 100 and its surroundings. It is sufficient that the storage case 30 is disposed at least rearward of the front operating lever 17.

[0035] A detailed configuration of the storage case 30 will be described with reference to Fig. 5 to Fig. 7. Fig. 5 is a perspective view of the storage case 30, illustrating the right side portion 32 of the storage case 30 shown in Fig. 4. Fig. 6 is a diagram showing a state in which a mobile terminal M, which is an example of an article, is stored in the storage case 30. Fig. 7 is a schematic cross-sectional view of the storage case 30 shown in Fig. 6, cut along a plane along the front-rear and up-down directions.

[0036] The storage case 30 has an opening 31, a pair of side surfaces 32, bottom surfaces 33 and 34, and a return surface 35. The pair of side surfaces 32, the bottom surfaces 33 and 34, and the return surface 35 are manufactured using, for example, sheet metal.

[0037] Opening 31 is formed in a rectangular shape that is long in the front-rear direction and short in the left-right direction of driver's seat 8, and is open upward. Opening 31 has a front side 31a, a rear side 31b, a left side 31c, and a right side 31d.

[0038] The pair of side surface portions 32 face each other and extend downward from the left side 31c and the right side 31d of the opening 31. Each of the pair of side surface portions 32 may be formed in a trapezoidal shape.

[0039] The bottom surface portions 33, 34 are disposed below the opening 31. The bottom surface portions 33, 34 are inclined in the up-down direction with respect to the horizontal plane H and disposed between the pair of side surface portions 32. The bottom surface portions 33, 34 have a first bottom surface portion 33 and a second bottom surface portion. The joint portion between the first bottom surface portion 33 and the second bottom surface portion 34 forms the deepest portion of the storage case 30. The first bottom surface portion 33 and the second bottom surface portion 34 may be formed in a rectangular shape.

[0040] The first bottom surface portion 33 extends obliquely downward from the front side 31a of the opening 31 toward the rear, or from the rear side 31b of the opening 31 toward the front. That is, the base end 33a of the first bottom surface portion 33 in the downward oblique direction contacts the front side 31a or the rear side 31b of the opening 31. In the storage case 30 shown in FIGS. 5 to 7, the first bottom surface portion 33 extends obliquely downward from the rear side 31b of the opening 31 toward the front. In the storage case 30 shown in FIGS. 5 to 7, the base end 33a of the first bottom surface portion 33 forms the rear end of the first bottom surface portion 33 and contacts the rear side 31b of the opening 31. In the storage case 30 shown in FIGS. 5 to 7, the tip end 33b of the first bottom surface portion 33 in the downward oblique direction constitutes the front end of the first bottom surface portion 33.

[0041] The second bottom surface portion 34 extends obliquely upward from the tip 33b of the first bottom surface portion 33. That is, the base end 34a of the second bottom surface portion 34 in the upward oblique direction is joined to the tip 33b of the first bottom surface portion 33. In the storage case 30 shown in Figs. 5 to 7, the second bottom surface portion 34 extends obliquely upward from the tip 33b of the first bottom surface portion 33 toward the front. In the storage case 30 shown in Figs. 5 to 7, the base end 34a of the second bottom surface portion 34 constitutes the rear end of the second bottom surface portion 34 and is joined to the tip 33b of the first bottom surface portion 33. In the storage case 30 shown in Figs. 5 to 7, the tip 34b of the second bottom surface portion 34 in the upward oblique direction constitutes the front end of the second bottom surface portion 34. The length of the second bottom surface portion 34 is shorter than the length of the first bottom surface portion 33. The second bottom surface portion 34 may be perpendicular to the first bottom surface portion 33.

[0042] The turned surface portion 35 is disposed below the opening 31. The turned surface portion 35 is disposed between the pair of side surface portions 32, inclined vertically with respect to the horizontal plane H. The turned surface portion 35 extends obliquely upward from the tip 34b of the second bottom surface portion 34 along the first bottom surface portion 33. That is, the base end 35a in the upward oblique direction of the turned surface portion 35 is joined to the tip 34b of the second bottom surface portion 34. The tip 35b in the upward oblique direction of the turned surface portion 35 is in contact with the front side 31a or the rear side 31b of the opening 31. In the storage case 30 shown in FIGS. 5 to 7, the turned surface portion 35 extends obliquely upward from the tip 34b of the second bottom surface portion 34 toward the rear to the front side 31a of the opening 31. In the storage case 30 shown in FIGS. 5 to 7, the base end 35a of the turned surface portion 35 constitutes the front end of the turned surface portion 35. 5 to 7, a tip 35b of the turned-up surface portion 35 forms the rear end of the turned-up surface portion 35 and contacts the front side 31a of the opening 31. The length of the turned-up surface portion 35 is shorter than the length of the second bottom surface portion 34. The turned-up surface portion 35 may be perpendicular to the second bottom surface portion 34.

[0043] In this way, since the storage case 30 has the return surface portion 35 as described above, even if a large vibration occurs in the construction machine 100, the first bottom surface portion 33, the second bottom surface portion 34, and the return surface portion 35 can come into surface contact with the stored item, so that the behavior of the item can be reliably regulated. Therefore, even if a large vibration occurs in the construction machine 100, the storage case 30 can prevent the item from falling out of the storage case 30. Therefore, even if a large vibration occurs in the construction machine 100, the storage case 30 provided in the console box 10 around the driver's seat 8 can stably hold the item.

[0044] In addition, since the first bottom surface portion 33 and the second bottom surface portion 34 of the storage case 30 are arranged at an incline in the vertical direction relative to the horizontal plane H, when the item is a portable terminal M, the operator can view the screen of the portable terminal M while the portable terminal M is stored.

[0045] Furthermore, it is preferable that the inclination angles θ1 to θ3 of the first bottom surface portion 33, the second bottom surface portion 34, and the return surface portion 35 of the storage case 30 relative to the horizontal plane H be equal to or greater than a maximum climbing angle (e.g., 35 degrees) and less than 90 degrees that is predetermined based on the climbing ability of the construction machine 100. This makes it possible for the storage case 30 to prevent items from falling out of the storage case 30 even if the construction machine 100 is tilted up to the maximum climbing angle.

[0046] Moreover, the first bottom surface portion 33 is longer than the second bottom surface portion 34 and is perpendicular to the second bottom surface portion 34. The return surface portion 35 is shorter than the second bottom surface portion 34 and is perpendicular to the second bottom surface portion 34. As a result, when the article is a rectangular thin plate-like article such as a mobile terminal M, the storage case 30 can bring the first bottom surface portion 33 and the return surface portion 35 into surface contact along the longitudinal side surface of the article, and can bring the second bottom surface portion 34 into surface contact along the lateral side surface of the article. Therefore, even if a large vibration occurs in the construction machine 100, the storage case 30 can regulate the behavior of the article and prevent the article from falling out of the storage case 30.

[0047] In particular, the return surface portion 35 is parallel to the first bottom surface portion 33. As a result, even if a large vibration occurs in the construction machine 100, the storage case 30 can more reliably regulate the behavior of the object because the longitudinal side of the rectangular thin plate-like object such as the mobile terminal M and the return surface portion 35 can be in surface contact with each other. Therefore, even if a large vibration occurs in the construction machine 100, the storage case 30 can further prevent the object from falling out of the storage case 30. In addition, since the return surface portion 35 is parallel to the first bottom surface portion 33, the storage case 30 can suppress interference between the return surface portion 35 and the object when the object is put in or taken out. Therefore, the storage case 30 can easily take in or take out the object, ensuring convenience.

[0048] Furthermore, the return surface portion 35 is disposed at a position where the tip 35b of the return surface portion 35 in contact with the opening 31 overlaps with the second bottom surface portion 34 in the front-rear direction (i.e., a position between the base end 34a and the tip 34b). Specifically, the tip 35b of the return surface portion 35 in contact with the opening 31 is disposed forward of the deepest part of the storage case 30 formed at the joint between the first bottom surface portion 33 and the second bottom surface portion 34. The return surface portion 35 is disposed below the horizontal plane H passing through the base end 33a of the first bottom surface portion 33 in contact with the opening 31. As a result, the return surface portion 35 of the storage case 30 does not protrude above the opening 31, so that it is possible to prevent interference between the operator's hand or the object and the return surface portion 35 when putting in or taking out the object. Therefore, the storage case 30 can make it easier to put in and take out the object while preventing the object from falling out of the storage case 30, and can further ensure convenience. Moreover, when the storage case 30 is viewed from above the opening 31, the deepest part of the storage case 30 formed at the joint between the first bottom part 33 and the second bottom part 34 can be seen without being in a blind spot. Therefore, even if small items such as keys are accidentally dropped into the storage case 30, the small items gather in the deepest part, making it easy to take out the small items. As a result, the storage case 30 makes it easier to take in and out items while preventing items from falling out of the storage case 30, and further ensures convenience.

[0049] Further, as shown in FIG. 6, the storage case 30 is disposed below the lower end 7e of the window 7d provided on the side panel 7c of the cab box 7. This allows the storage case 30 to prevent the stored items from being exposed to direct sunlight. In particular, the storage case 30 is disposed at a position farther from the driver's seat 8 in the left-right direction than the operation levers 9, 11, 17, 19 and the operation switches 21a to 24, and therefore can be disposed adjacent to the side panel 7c and below the lower end 7e of the window 7d. This allows the storage case 30 to further prevent the stored items from being exposed to direct sunlight. In the case where the item is a mobile terminal M, direct sunlight increases the temperature of the mobile terminal M, which tends to promote failure of the mobile terminal M. Since the storage case 30 can prevent the mobile terminal M from being exposed to direct sunlight, failure of the mobile terminal M can be suppressed. Furthermore, it is preferable that the storage case 30 is disposed below the frame 7f that is in contact with the lower end 7e of the window 7d and extends in the front-rear direction. As a result, the storage case 30 can further protect the portable terminal M from direct sunlight, and therefore failure of the portable terminal M can be further suppressed.

[0050] Furthermore, the storage case 30 is disposed rearward of the front operation lever 17 and the blade operation lever 11. The first bottom surface portion 33 extends obliquely downward from the rear edge 31b of the opening 31 toward the front. The second bottom surface portion 34 extends obliquely upward from the tip 33b of the first bottom surface portion 33 toward the front. The return surface portion 35 extends obliquely upward from the tip 34b of the second bottom surface portion 34 toward the rear to the front edge 31a of the opening 31. This allows the storage case 30 to take in and out items toward the opposite side of the front operation lever 17, etc., when taking items in and out, and prevents the front operation lever 17, etc. from interfering with the operator's hand. In addition, even if a large vibration occurs in the construction machine 100 and an item falls out of the storage case 30, the return surface portion 35 can restrict the direction in which the item falls out to the opposite side of the front operation lever 17, etc., and can prevent the item from interfering with the front operation lever 17, etc. Therefore, the storage case 30 can further prevent the front operating lever 17, etc. from being operated accidentally when putting items in or taking them out, which would otherwise compromise the safety of the construction machine 100 and its surroundings.

[0051] Furthermore, in the storage case 30, a protective member 36 is provided on the tip 35b of the return surface 35 that contacts the opening 31 to protect the stored items. In the storage case 30 shown in Figs. 5 to 7, the protective member 36 is provided on the tip 35b of the return surface 35 that contacts the front side 31a of the opening 31. The protective member 36 is made of a trim material that covers the tip 35b of the return surface 35. The protective member 36 is manufactured using rubber that has excellent weather resistance, such as ethylene propylene rubber. This makes it possible for the storage case 30 to prevent the tip 35b of the return surface 35, which is easily sharpened, from coming into contact with and damaging the items.

[0052] The protective member 36 may be provided not only on the tip 35b of the return surface 35 but also, for example, on the upper end of the right side surface 32 that contacts the right side 31d of the opening 31. The protective member 36 may be made of a trim material that also covers the upper end of the right side surface 32. This makes it possible for the storage case 30 to prevent the upper end of the right side surface 32, which is likely to become sharp, from coming into contact with and damaging an article.

[0053] Furthermore, the storage case 30 is provided with a protective member 37 on the inner surface of at least one of the pair of side surface portions 32 to protect the stored items. In the storage case 30 shown in Figs. 5 to 7, the protective member 37 is provided on the upper part of the inner surface of the left side surface portion 32 that contacts the left side 31c of the opening 31. The protective member 37 is made of a cushioning material that covers the upper part of the inner surface of the left side surface portion 32. The protective member 37 is manufactured using, for example, urethane. This allows the storage case 30 to prevent the stored items from colliding with the inner surface of the side surface portion 32 and damaging the items. Note that, in the storage case 30 shown in Figs. 5 to 7, the protective member 36 is provided on the upper end of the right side surface portion 32 that contacts the right side 31d of the opening 31, so there is no need to provide the protective member 37 on the upper part of the inner surface of the right side surface portion 32. However, the protective member 37 may be provided on the upper part of the inner surface of the right side surface portion 32, or on the inner surfaces of the bottom surface portions 33, 34 and the return surface portion 35.

[0054] FIG. 8 is a diagram showing a modified example of the storage case 30 shown in FIGS.

[0055] In the storage case 30 shown in Figures 5 to 7, the first bottom surface portion 33 extends diagonally downward toward the front from the rear edge 31b of the opening 31, the second bottom surface portion 34 extends diagonally upward toward the front from the tip 33b of the first bottom surface portion 33, and the return surface portion 35 extends diagonally upward toward the rear from the tip 34b of the second bottom surface portion 34 to the front edge 31a of the opening 31.

[0056] However, as shown in FIG. 8, the storage case 30 may have a first bottom surface portion 33 extending diagonally downward from the front edge 31a of the opening 31 toward the rear, a second bottom surface portion 34 extending diagonally upward from the tip 33b of the first bottom surface portion 33 toward the rear, and a return surface portion 35 extending diagonally upward from the tip 34b of the second bottom surface portion 34 toward the front to the rear edge 31b of the opening 31.

[0057] Even with the configuration shown in Figure 8, like the storage case 30 shown in Figures 5 to 7, the storage case 30 can prevent items from falling out of the storage case 30 when large vibrations occur in the construction machine 100.

[0058] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to each embodiment, and various modifications can be made without departing from the spirit of the present invention. In the present invention, components of one embodiment can be added to components of another embodiment, components of one embodiment can be replaced with components of another embodiment, or some components of one embodiment can be deleted.
