[0007] According to the above-described embodiment, the convenience of the storage compartment for keeping contents cool or warm inside the shovel cabin can be further improved. [Brief explanation of the drawing]
[0008] [Figure 1] This is an external view showing an example of a shovel. [Figure 2] This is a plan view showing an example of the interior configuration of a cabin. [Figure 3] This is a perspective view showing an example of a detention facility. [Figure 4] This is a front view showing an example of a storage facility. [Figure 5] This is a diagram showing an example of a stopper structure. [Modes for carrying out the invention]
[0009] Embodiments will be described below with reference to the drawings.
[0010] [Shovel Overview] Referring to Figure 1, the outline of the excavator according to this embodiment will be described.
[0011] Figure 1 is an external view (left side view) of an example of an excavator. Hereafter, as shown in Figure 1, the direction in which the boom 4 (attachment) extends when the excavator is viewed from directly above will be defined and explained as "front," and the directions of "front," "rear," "left," "right," "up," and "down" will be defined accordingly.
[0012] As shown in FIG. 1, the excavator includes a lower traveling body 1, an upper revolving body 3 mounted on the lower traveling body 1 so as to be revolvable via a revolving mechanism 2, an attachment AT, and a cab 10. The excavator also includes an engine 11 and a controller 30.
[0013] The lower traveling body 1 includes a pair of left and right crawlers and is hydraulically driven by traveling hydraulic motors mounted on respective ones of the left and right crawlers to cause the excavator to travel.
[0014] The upper revolving body 3 revolves with respect to the lower traveling body 1 when the revolving mechanism 2 is hydraulically driven by a revolving hydraulic motor.
[0015] The attachment AT includes a boom 4, an arm 5, and a bucket 6.
[0016] The boom 4 is attached to the center in the left - right direction at the front part of the upper revolving body 3 so as to be able to pitch. An arm 5 is attached to the tip of the boom 4 so as to be rotatable about an axis in the left - right direction, and a bucket 6 is attached to the tip of the arm 5 so as to be rotatable about an axis in the left - right direction.
[0017] The bucket 6 is an example of an end attachment. The bucket 6 is used, for example, in excavation work or the like.
[0018] Also, at the tip of the arm 5, depending on the work content or the like, another end attachment may be attached instead of the bucket 6. The other end attachment may be, for example, other types of buckets such as a large bucket, a slope bucket, a dredging bucket, etc. Also, the other end attachment may be an end attachment of a type other than a bucket such as a stirrer, a breaker, a grapple, etc. Further, between the arm 5 and the end attachment, a preliminary attachment such as a quick coupler or a tilt - rotator may be interposed.
[0019] Furthermore, a hook for crane operations may be attached to the bucket 6. The base end of the hook is rotatably connected to a bucket pin that connects the arm 5 and the bucket 6. As a result, when operations other than crane operations (lifting operations), such as excavation work, are performed, the hook is stored in the space formed between the two bucket links.
[0020] The boom 4, arm 5, and bucket 6 are hydraulically driven by the boom cylinder 7, arm cylinder 8, and bucket cylinder 9, respectively, which act as hydraulic actuators.
[0021] Cabin 10 is the driver's cabin where the operator sits. Cabin 10 is mounted, for example, on the front left side of the upper rotating body 3, and an entrance / exit is provided on the left side.
[0022] Engine 11 is the prime mover for the shovel and drives the hydraulic pump, which serves as the hydraulic power source for the shovel. Engine 11 is mounted, for example, at the rear of the upper rotating body 3.
[0023] The controller 30 performs various controls related to the excavator. For example, the controller 30 directly or indirectly controls the operation of the engine 11 and the hydraulic pump. The controller 30 is mounted, for example, inside the cabin 10.
[0024] Furthermore, in the excavator according to this embodiment, some or all of the various hydraulic actuators may be replaced with electric actuators. Also, the excavator according to this embodiment may have another type of prime mover (for example, an electric motor) in addition to or instead of the engine 11 as a prime mover. In other words, the excavator according to this embodiment may be a hybrid excavator or an electric excavator.
[0025] [Cabin Interior Configuration] Next, with reference to Figure 2, the internal configuration of the cabin 10 will be described.
[0026] Figure 2 is a plan view showing an example of the internal configuration of the cabin 10. The white arrows in the figure represent the airflow from the air conditioning unit 150.
[0027] A driver's seat 100 is installed in the center of the cabin 10.
[0028] The driver's seat 100 includes a seat surface 102 and a backrest 104 for the operator to sit on. The driver's seat 100 has a sliding mechanism that allows for adjustment of its position in the front-to-back direction, and also has a reclining mechanism that allows for adjustment of the tilt angle of the backrest 104.
[0029] Armrests 106A and 106B are provided at relatively high positions on the left and right rear sides of the driver's seat 100, extending in the front-to-back direction adjacent to the driver's seat 100. The armrests 106A and 106B are positioned somewhat higher than the seat surface 102, so as to support the operator's forearms from below. The armrests 106A and 106B are attached, for example, directly or indirectly to the base of the driver's seat 100 and are supported so as to be able to rotate up and down about a left-right axis at their rear ends. This allows the posture angle of the armrests 106A and 106B to be changed.
[0030] Furthermore, consoles 120A and 120B are provided on the left and right sides of the driver's seat 100, extending in the front-to-back direction over the range in which the driver's seat 100 is located.
[0031] Operating levers 26A and 26B are provided on the upper surface of the front end of consoles 120A and 120B, respectively. This allows the operator, for example, to operate the boom 4 (boom cylinder 7), arm 5 (arm cylinder 8), bucket 6 (bucket cylinder 9), and upper slewing body 3 (hydraulic motor for slewing) by sitting in the driver's seat 100 and operating the operating levers 26A and 26B. Covers 27 are attached to the bases of the operating levers 26A and 26B.
[0032] In the front of the cabin 10, specifically on the floor in front of the driver's seat 100, travel pedals 26C, 26D and travel levers 26E, 26F are provided. This allows the operator, for example, to operate the lower travel body 1, that is, the pair of left and right crawlers (hydraulic motors for travel), by sitting in the driver's seat 100 and operating the travel pedals 26C, 26D and the travel levers 26E, 26F.
[0033] Furthermore, as described above, the driver's seat 100 is slidable forward and backward. This allows the operator to fix the driver's seat 100 in a position that makes it easy to operate, for example, the driving pedals 26C, 26D and the driving levers 26E, 26F. Also, for example, the consoles 120A, 120B may be fixed to the cabin 10, and the driver's seat 100 may be slidable forward and backward relative to the consoles 120A, 120B. This allows the operator to fix the driver's seat 100 in a position that makes it easy to operate, for example, the operating levers 26A, 26B. The driver's seat 100 may also be slidable forward and backward together with the consoles 120A, 120B. In this case, a separate mechanism may be provided to adjust the forward and backward position of the consoles 120A, 120B relative to the driver's seat 100. This allows the operator to fix the consoles 120A, 120B in a position that makes it easy to operate, for example, the operating levers 26A, 26B.
[0034] A gate bar 140 is attached to the front of the front end of the left console 120A.
[0035] The gate bar 140 operates in conjunction with the operation state of a gate lever (not shown) provided on the console 120A. The gate bar 140 is mounted on the internal frame of the console 120A so as to be able to move up and down about a left-right axis at its upper end.
[0036] The gate lever is a mechanical input (operation part) for switching between a state in which the shovel can be started and operated using the operating levers 26A, 26B, travel pedals 26C, 26D, and travel levers 26E, 26F, and a state in which the shovel cannot be started or operated. Specifically, the controller 30 controls whether or not to allow the shovel to be started, including starting the engine 11, according to the operating state of the gate lever. In addition, the state in which the shovel can be operated and the state in which it cannot be operated are switched by switching the connection and disconnection of the hydraulic lines from the hydraulic pump to various hydraulic equipment according to the operating state of the gate lever.
[0037] When the gate lever is in the position to operate the shovel, the gate bar 140 is raised forward (as shown in Figure 2) to block lateral movement between the driver's seat 100 and the entrance / exit of the cabin 10. On the other hand, when the gate lever is in the position to disengage the shovel, the gate bar 140 is retracted downward and housed inside the console 120A to allow lateral movement between the driver's seat 100 and the entrance / exit of the cabin 10. As a result, unless the gate bar 140 is extended forward in response to the gate bar operation, the operator cannot start or operate the shovel, thereby improving the safety of the shovel.
[0038] In console 120B, a switch panel 41 is provided behind the operating lever 26B and in front of the armrest 106B. The switch panel 41 includes a dial 32 and various switch groups 41a.
[0039] Dial 32 is used to adjust the rotational speed of engine 11. An output characteristic selector switch 35 is provided on the top surface of dial 32. For example, pressing the output characteristic selector switch 35 switches the output characteristics of the shovel. The output characteristics of the shovel include, for example, the acceleration and deceleration characteristics of the hydraulic actuator in response to the operation of the operating levers 26A, 26B, the travel pedals 26C, 26D, and the travel levers 26E, 26F.
[0040] The switch group 41a includes, for example, a travel speed switch, a backup circuit switch, a crane mode switch, a work light switch, a wiper switch, a washer switch, etc. The travel speed switch is used, for example, to switch the travel speed of the shovel in two stages. The backup circuit switch is used to switch the operation (on) and stop (off) of the backup circuit for operating a backup attachment, and to switch the flow of hydraulic fluid in the backup circuit (one-way and two-way). The crane mode switch is used to switch the operation (on) and stop (off) of the crane mode for performing crane work. The work light switch is used to switch the lighting (work light) installed on the front of the upper slewing body 3 on and off. The wiper switch is used to switch the operation (on) and stop (off) of the wiper for the front window of the cabin 10. The washer switch is used to activate the function of spraying washer fluid onto the front of the cabin 10.
[0041] To the right of console 120B, console 120C is provided, which extends in the front-to-back direction along the left side of the interior of cabin 10.
[0042] In console 120C, the ignition switch 42, radio 43, and rocker switch 44 are arranged in a front-to-back direction on the right side of the driver's seat 100.
[0043] The rocker switch 44 is configured to accept input from the operator regarding relatively frequently used auxiliary functions. For example, the rocker switch 44 may be assigned functions such as switching auxiliary circuits used by auxiliary attachments such as grapples and lifting magnets, turning on the work lights mentioned above, and outputting a travel alarm.
[0044] A display device 33 is provided at the front end of the console 120C, that is, in the front right corner inside the cabin 10. This allows the operator to operate the shovel while checking various information images displayed on the display device 33. The display device 33 is equipped with a group of switches 34 for receiving input related to the display device 33.
[0045] A trim section 130 is provided in the interior of the cabin 10 behind the driver's seat 100, extending to both the left and right ends. The trim section 130 has the function of covering various equipment mounted at the rear of the cabin 10, as well as functioning as a storage space for the operator's luggage and other items.
[0046] An air conditioning unit 150 is installed on the inside (bottom) of the trim section 130 behind the driver's seat 100.
[0047] The air conditioning unit 150 adjusts the temperature and humidity of the air inside the cabin 10. Specifically, the air conditioning unit 150 draws in air from inside the cabin 10 or outside the cabin 10 and adjusts the temperature and humidity of the air by mixing it with the air generated by heat exchange between the cooling source and the high heat source, respectively. The air whose temperature and humidity have been adjusted by the air conditioning unit 150 is sent through the air conditioning duct 155 to the front and rear of the cabin 10 and to the interior of the storage compartment 160.
[0048] Air conditioning duct 155 includes air conditioning ducts 155A to 155C.
[0049] Air conditioning duct 155A extends forward from the air conditioning unit 150 and is located inside (below) the trim section 130 and console 120C. The tip of air conditioning duct 155A is connected to outlets 121F1 and 121F2 provided at the front end of console 120C. This allows air whose temperature and humidity have been adjusted by the air conditioning unit 150 to be supplied to the front of the cabin 10. Air conditioning duct 155B extends rearward from the air conditioning unit 150 and is located inside (below) the trim section 130. Air conditioning duct 155B then branches into air conditioning ducts 155BL and 155BR, with their respective ends connected to the left outlet 131BL and the right outlet 131BR inside the cabin 10. This allows air whose temperature and humidity have been adjusted by the air conditioning unit 150 to be supplied to the rear of the cabin 10. The air conditioning duct 155C extends to the right from the air conditioning unit 150 and is positioned inside (below) the trim section 130. The end of the air conditioning duct 155C is connected to the storage compartment 160. This allows air whose temperature and humidity have been regulated by the air conditioning unit 150 to be supplied to the inside of the storage compartment 160.
[0050] The air conditioning ducts 155A to 155C may be configured such that air with the same conditions, such as temperature and humidity, passes through them, or at least a portion of them may be configured such that air with different conditions, such as temperature and humidity, passes through them. For example, the temperature and other conditions of the air supplied to the storage compartment 160 through air conditioning duct 155C may differ from the temperature and other conditions of the air supplied to the interior of the cabin 10 through air conditioning ducts 155A and 155B.
[0051] Furthermore, the conditions such as airflow rate and temperature of the air supplied to the interior of the cabin 10 through the air conditioning ducts 155A and 155B can be set by the operator via a predetermined input unit (for example, a switch included in switch group 34 or switch group 41a). In addition, the conditions such as airflow rate and temperature supplied to the storage compartment 160 through the air conditioning duct 155C can be set by the operator independently of the air supplied to the interior of the cabin 10 through the air conditioning ducts 155A and 155B via a predetermined input unit (for example, a switch included in switch group 34 or switch group 41a). For example, a mechanism may be provided for switching the inflow and blocking of air from the air conditioning unit 150 to the storage compartment 160 through the air conditioning duct 155C, and for adjusting the airflow rate, and this mechanism may be operated by the operator. Specifically, it may be possible to physically switch between airflow and shutoff or adjust the airflow volume using a lever or the like, or it may be possible to switch between airflow and shutoff or adjust the airflow volume using switches included in switch group 34 or switch group 41a.
[0052] A storage compartment 160 is provided at the front right corner of the trim section 130.
[0053] The storage compartment 160 has the function of keeping the contents inside cool or warm. Specifically, the storage compartment 160 keeps the contents cool or warm by air supplied through the air conditioning duct 155C, whose temperature is regulated by the air conditioning device 150. The contents may include, for example, containers of beverages such as plastic bottles or lunch boxes.
[0054] The storage compartment 160 is installed along the front-to-back direction inside the window 10WR (see Figure 4) on the right side of the cabin 10. In this example, the storage compartment 160 is positioned diagonally to the right and behind the driver's seat 100, with the majority of it located behind the driver's seat 100 in the front-to-back direction, and the entire compartment located outside (to the right of) the driver's seat 100 in the width direction (left-to-right direction). This improves operator convenience by making it easier for the operator to reach and access the storage compartment 160 compared to, for example, when it is located behind the driver's seat.
[0055] Furthermore, a portion of the storage compartment 160 may be positioned outside the width of the driver's seat 100. Also, a portion or all of the storage compartment 160 may be positioned to the left of the driver's seat 100. In addition, the storage compartment 160 may be positioned entirely behind the driver's seat 100 in the front-to-rear direction, or it may be positioned so as to overlap with the area where the driver's seat is located. Moreover, instead of being supplied with temperature-controlled air from the air conditioning unit 150, the storage compartment 160 may achieve the function of keeping the contents cool or warm by other means. For example, the storage compartment 160 may keep the contents cool or warm by a heat pump using a Peltier element. Furthermore, the storage compartment 160 may have only one of the functions of keeping the contents cool or warm.
[0056] As shown in Figure 2, in a plan view of the cabin 10, no input units (operators) such as switches that the operator would operate are located in the opposing space between the rear right corner of the driver's seat 100 and the storage compartment 160. In a plan view of the cabin 10, the opposing space between the lower right corner of the driver's seat 100 and the storage compartment 160 corresponds to the movement path for the operator's hands and arms to access the storage compartment 160. This prevents the operator from accidentally operating various input units (operators) when accessing the storage compartment 160 with their hands and arms.
[0057] Furthermore, in a plan view of the cabin 10, in the opposing space between the rear right corner of the driver's seat 100 and the storage compartment 160, input units such as switches may be located under the right armrest 106B. This is because, when the operator accesses the storage compartment 160, the armrest 106B is very likely to be in a lowered position, and even if input units such as switches are located under the armrest 106B, there is no possibility of the operator's hand or arm coming into contact with them.
[0058] [Storage structure of the detention center] Next, the structure of storage 160 will be described with reference to Figures 3 to 5.
[0059] Figure 3 is a perspective view showing an example of the storage compartment 160. Specifically, it is a perspective view showing an example of the storage compartment 160 when the cover portion 162 is fully open. Figure 4 is a front view showing an example of the storage compartment 160. Specifically, Figure 4 is a front view showing an example of the storage compartment 160 when the cover portion 162 is fully open. Figure 5 is a diagram showing an example of the structure of the stopper 163E. Specifically, Figure 5 shows the storage compartment 160 when the cover portion 162 is fully closed (Figure 5A) and the storage compartment 160 when the cover portion 162 is fully open (Figure 5B), viewed from a direction along the rotation axis of the opening / closing mechanism portion 163 (hinge 163A).
[0060] As shown in Figures 3 to 5, the storage compartment 160 includes a storage section 161, a cover section 162, an opening / closing mechanism section 163, and a fixing mechanism section 164.
[0061] The housing section 161 includes an upper surface section 161A, a left side surface section 161B, a rear surface section 161C, a recess 161D, a seat surface section 161E, a recessed section 161F, and a recessed section 161G.
[0062] The upper surface portion 161A (an example of an opposing portion) faces the back surface of the cover portion 162 when the storage compartment 160 (cover portion 162) is in a fully closed state. An opening 161A1 is provided in the upper surface portion 161A.
[0063] The left side portion 161B slopes down from the left end of the top portion 161A, so as to be continuous with the left trim portion 130. The left side portion 161B covers the left side of the recess 161D.
[0064] The rear section 161C rises upward from the rear end of the upper section 161A so as to be continuous with the trim section 130 at the rear of the storage compartment 160.
[0065] The recess 161D is recessed so as to be continuous downward from the opening 161A1 of the upper surface portion 161A. This allows the operator to place beverage containers, lunch boxes, etc., in the recess 161D. The end of the air conditioning duct 155C is connected to the recess 161D, and air whose temperature has been adjusted by the air conditioning device 150 is supplied through the air conditioning duct 155B.
[0066] Two seat portions 161E are provided side by side in the front-to-back direction to the right of the opening 161A1 of the upper portion 161A. An opening / closing mechanism 163 (seat plate 163C) is attached to the seat portions 161E.
[0067] The recessed portion 161F is provided on the front side of the storage compartment 160 (top surface portion 161A). Specifically, the recessed portion 161F is provided on the front side of the corner where the top surface portion 161A and the left side surface portion 161B connect. The operator's fingertips can be inserted into the recessed portion 161F even when the cover portion 162 is fully closed. This allows the operator to insert their fingers into the recessed portion 161F and lift the cover portion 162 upwards to open the cover portion 162.
[0068] The recessed portion 161G is provided on the right side of the corner where the upper surface portion 161A and the rear surface portion 161C connect. A seating surface for the bolt BLT1 is provided at the innermost part of the rear side of the recessed portion 161G. This allows the trim corresponding to the housing portion 161 to be fixed to the body of the cabin 10 using the recessed portion 161G. In addition, when fully closed, the recessed portion 161G faces the wall portion 162A of the cover portion 162, which will be described later, and forms a gap between the wall portion 162A and the wall portion 162A that is larger than the gap between the wall portion 162A and the other parts of the upper surface portion 161A. As a result, the recessed portion 161G functions as an escape route for the air supplied from the air conditioning unit 150 to the recessed portion 161D. Therefore, it is possible to prevent a situation in which the pressure in the recessed portion 161D becomes relatively high and air from the air conditioning unit 150 cannot be supplied to the recessed portion 161D.
[0069] The cover portion 162 covers the opening 161A1 of the storage portion 161 from above so that it can be opened and closed. The cover portion 162 is opened by the opening and closing mechanism portion 163, which rotates it from a face down position covering the opening 161A1 to an outward position in the width direction, i.e., to the right.
[0070] Furthermore, the cover portion 162 may open by moving outward in the width direction in a manner other than rotating upward. For example, the cover portion 162 may open by sliding to the right and close by sliding to the left.
[0071] A wall portion 162A is provided on the back side of the cover portion 162.
[0072] The wall portion 162A protrudes from the back surface of the cover portion 162 and, when the cover portion 162 is fully closed, is provided to surround the opening 161A1 when viewed from the vertical direction of the opening 161A1. The amount of protrusion of the wall portion 162A from the cover portion 162 is set to be as small as possible without contacting the upper surface portion 161A when the cover portion 162 is fully closed. As a result, the wall portion 162A makes it difficult for the air supplied to the recess 161D through the air conditioning duct 155B to escape to the outside. Therefore, the cooling and heating performance of the contents of the storage compartment 160 can be improved.
[0073] The opening / closing mechanism 163 supports the cover portion 162 so that it can be opened and closed. The opening / closing mechanism 163 includes a hinge 163A, seat plates 163B and 163C, a coil spring 163D, and a stopper 163E.
[0074] The hinge 163A is configured such that when the cover portion 162 is opened, it rotates to the right and rises up. One of the hinge blades is attached to the back surface of the cover portion 162 via the seat plate 163B, and the other hinge blade is attached to the seat portion 161E via the seat plate 163C. Two hinges 163A are provided, one at the front and one at the back, and are arranged so that their axes of rotation are approximately coaxial.
[0075] Furthermore, the opening / closing mechanism 163 may open the cover portion 162 in a manner other than rotating and rising. For example, the opening / closing mechanism 163 may be configured to include a sliding mechanism that slides the cover portion 162 in the left-right direction.
[0076] The seat plate 163B is, for example, a metal plate or a pressed metal plate, and is attached to the back surface of the cover portion 162, to which one of the hinge 163A is fixed.
[0077] The seat plate 163C is, for example, a metal plate-shaped member or a pressed product of a plate-shaped member, and is attached to the upper surface of the seat portion 161E. Two seat plates 163C are provided, corresponding to the two seat portions 161E, and the seat plate 163C attached to the front seat portion 161E has a protrusion 163C1 that extends forward from the upper surface of the seat portion 161E.
[0078] The coil spring 163D (an example of a biasing member) is incorporated into the rotational axis of the hinge 163A, biasing the hinge 163A in the direction that opens the cover portion 162. This allows the operator to easily open the cover portion 162 with relatively little force.
[0079] Furthermore, if it is possible to apply a biasing force in the direction that opens the cover portion 162, other components may be used instead of the coil spring 163D.
[0080] The stopper 163E (an example of a limiting member) is attached to the front end of the seat plate 163B and restricts the amount of movement (rotation) of the cover portion 162 when it is opened. Specifically, the stopper 163E has a shape in which a plate-shaped member is bent into an L shape, with one flat portion attached to the seat plate 163B and the other flat portion protruding vertically from the seat plate 163B, and is positioned approximately at the same front-to-back position as the protrusion 163C1 of the seat plate 163C. As shown in Figure 5A, when the cover portion 162 is fully closed, the other flat portion of the stopper 163E is separated from the protrusion 163C1 of the seat plate 163C. On the other hand, when the hinge 163A rotates in the direction that opens the cover portion 162, the other flat portion of the stopper 163E rotates to approach the convex portion 163C1, and as shown in Figure 5B, when the cover portion 162 is fully open, it comes into contact with the convex portion 163C1 of the seat plate 163C (see dashed circle in the figure). This prevents the cover portion 162 from over-stroking beyond its fully open state. Therefore, it prevents the cover portion 162 from coming into contact with the window 10WR. As a result, damage to the cover portion 162 and the window 10WR can be suppressed, as can the generation of abnormal noise (unpleasant noise for the operator) caused by contact between the cover portion 162 and the window 10WR.
[0081] Furthermore, if it is possible to suppress overstroke when the cover portion 162 opens, other components may be arbitrarily used instead of the combination of the stopper 163E and the protrusion 163C1 of the seat plate 163C.
[0082] As shown in Figure 4, a gap SP1 is provided between the fully open cover portion 162 and the window 10WR on the right side of the cabin 10. This allows the operator to insert their hand (e.g., fingers) between the window 10WR and the cover portion 162 to operate the fully open cover portion 162 and close it.
[0083] The widthwise (left-right) dimension of the gap SP1 between the fully open cover portion 162 and the window 10WR may be set to be relatively small enough that the operator can insert their hand (fingers) and operate it. For example, the widthwise dimension of the gap SP1 (upper end) is set to be sufficiently smaller than the left-right width of the fully closed cover portion 162. Alternatively, for example, the widthwise dimension of the gap SP1 (upper end) is set to be smaller than the left-right distance between the opening 161A1 and the window 10WR. Alternatively, for example, the widthwise dimension of the gap SP1 (upper end) is set to be smaller than the left-right (widthwise) dimension of the upper surface of the seat portion 161E. This allows the cover portion 162 to be opened relatively wider, making it easier for the operator to access the opening 161A1 (recess 161D).
[0084] Furthermore, the fully open cover portion 162 is tilted inward in the width direction, i.e., to the left. This makes it easier for the operator to close the cover portion 162 from the fully open position, improving operator operability.
[0085] The fixing mechanism 164 holds the cover portion 162 in a fully closed position by opposing the coil spring 163D incorporated in the hinge 163A. The fixing mechanism 164 includes a magnetic catch portion 164A and a receiving plate portion 164B.
[0086] The magnetic catch portion 164A is provided on the back surface of the cover portion 162, at the center in the front-to-back direction and at the left end (the inner end in the width direction).
[0087] The receiving plate portion 164B is attached to the upper surface portion 161A facing the magnetic catch portion 164A when the cover portion 162 is in the fully closed state. As a result, when the cover portion 162 is in the fully closed state, the magnetic catch portion 164A and the receiving plate portion 164B are magnetically attracted to each other, fixing the cover portion 162 in place. The attractive force between the magnetic catch portion 164A and the receiving plate portion 164B is set to be sufficiently greater than, for example, the force biasing the cover portion 162 in the opening direction by the coil spring 163D incorporated in the hinge 163A, and to the extent that the operator can release the fixed state with relatively little force. Furthermore, the attractive force between the magnetic catch portion 164A and the receiving plate portion 164B is adjusted so that, for example, the cover portion 162 does not spontaneously open due to vibrations during shovel operation.
[0088] [Effect] Next, the operation of the shovel according to this embodiment will be described.
[0089] In this embodiment, the shovel comprises a lower traveling body 1, an upper rotating body 3 that is rotatably mounted on the lower traveling body 1, a cabin 10 mounted on the upper rotating body 3 and having a driver's seat 100, and a storage compartment 160 provided inside the cabin 10 and having at least one of the functions of keeping the contents cold and warm. The storage compartment 160 is positioned outside the width direction of the driver's seat 100 inside the cabin 10.
[0090] This eliminates the need for the operator to stand up or bend forward from the driver's seat 100 when accessing the storage compartment 160, for example, when it is located directly below the driver's seat 100. Similarly, when it is located behind the driver's seat 100, for example, the operator does not need to stand up or twist their body while seated when accessing the storage compartment 160. Therefore, the convenience for the operator using the storage compartment 160 is improved.
[0091] Furthermore, in this embodiment, the storage compartment 160 may also include an opening 161A1, a cover portion 162 that covers the opening 161A1, and an opening / closing mechanism portion 163 that opens and closes the cover portion 162 in the width direction.
[0092] This allows the operator to open and close the cover portion 162 (storage compartment 160) by moving the cover portion 162 in the width direction. Therefore, from the perspective of the operator seated in the driver's seat 100, it is easier to operate the cover portion 162 than, for example, if the cover portion 162 were moved in the front-to-back direction. Thus, the convenience for the operator can be further improved.
[0093] Furthermore, in this embodiment, the cabin 10 may have an entrance / exit on its left side. The storage compartment 160 is located to the right of the driver's seat 100, and the opening / closing mechanism 163 may cause the cover portion 162 to open to the right.
[0094] This allows the operator to operate the storage compartment 160 (cover portion 162), which is located on the opposite side (right side) in the width direction when viewed from the entrance / exit of the cabin 10, outwards in the width direction (right side), thereby opening the storage compartment 160 (cover portion 162). For example, the operator can open the storage compartment 160 relatively easily than by operating it inwards in the width direction, i.e., towards the operator. Thus, the convenience for the operator can be further improved.
[0095] Furthermore, in this embodiment, it is not necessary to place an input unit that can be operated by the operator in the path of the operator's hands and arms in the driver's seat 100 to access the storage compartment 160.
[0096] This helps to prevent situations where the operator accidentally operates various input units when accessing the storage area 160.
[0097] Furthermore, in this embodiment, the opening / closing mechanism 163 may also include a coil spring 163D that biases the cover portion 162 in the opening direction, and a stopper 163E that limits the amount of movement of the cover portion 162 in the opening direction.
[0098] This allows the cover portion 162 to be opened with relatively little force, and also suppresses overstroke when the cover portion 162 opens. Therefore, for example, if the window 10WR is located in the direction of movement of the cover portion 162, it is possible to prevent the cover portion 162 from coming into contact with the window 10WR. As a result, damage to the cover portion 162 and the window 10WR can be suppressed, and the generation of abnormal noise (unpleasant noise for the operator) caused by contact between the cover portion 162 and the window 10WR can be suppressed.
[0099] In this embodiment, the storage compartment 160 may also be positioned along the side window 10WR of the cabin 10.
[0100] As a result, the storage compartment 160 is positioned at the outermost edge of the cabin 10. This allows for a greater widthwise offset between the driver's seat 100 and the storage compartment 160, making it easier for the operator to access the storage compartment 160 using their hands and arms.
[0101] Furthermore, in this embodiment, the cover portion 162 opens by rotating the opening / closing mechanism 163 so as to rise outward in the width direction, and in the fully open state, it is tilted inward.
[0102] This makes it easier for the operator to close the cover 162 because it is tilted inward in the width direction. Specifically, because it is tilted inward in the width direction, the operator can easily close the cover 162 simply by pushing down on the upper end of the cover 162. Therefore, the convenience for the operator can be further improved.
[0103] In this embodiment, the cover portion 162 may also be opened by the opening / closing mechanism 163, which rotates to rise in the width direction. The upper surface portion 161A, which has an opening 161A1 and faces the fully closed cover portion 162, may be provided with a recess 161F for inserting a hand under the fully closed cover portion 162.
[0104] This allows the operator to insert their hand into the recessed area 161F and lift the cover portion 162 from below. Therefore, the operator's ability to operate the cover portion 162 is improved.
[0105] Although embodiments have been described in detail above, this disclosure is not limited to these specific embodiments, and various modifications and changes are possible within the scope of the gist described in the claims. [Explanation of symbols]
