[0006] [Patent Document 1] Patent Publication No. 2021-102391 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the work vehicle 901 according to the above-described conventional technology, the power socket 954 is located on the front panel 940. Therefore, if the operator attempts to get in or out of the work vehicle 901 with a plug inserted in the power socket 954, the plug and electrical wiring (not shown) can get in the way and hinder the operator from getting in or out of the work vehicle 901, which is a problem.

[0008] Furthermore, there is a problem in that the operator may come into contact with the plug or electrical wiring, which may hinder the operation of the work vehicle 901.

[0009] Therefore, the present invention aims to solve such problems by providing a work vehicle equipped with a power socket that can prevent plugs and electrical wiring connected to the power socket from being placed in places where operators get on and off or where they operate machinery. [Means for solving the problem]

[0010] [1] The work vehicle of the present disclosure includes a bracket disposed on the side of the operator seat; a power socket supported by the bracket, the power socket having an insertion port facing rearward of the work vehicle.

[0011] [2] The work vehicle of the present disclosure further includes an armrest. Preferably, the armrest is disposed above the bracket.

[0012] [3] In the work vehicle of the present disclosure, it is preferable that the power sockets include a right-side power socket located on the right side of the operator seat and a left-side power socket located on the left side of the operator seat.

[0013] [4] In the work vehicle of the present disclosure, it is preferable that the work vehicle further includes a canopy pole erected behind the operator seat, and a mounting seat disposed on the canopy pole for mounting electrical equipment.

[0014] [5] In the work vehicle of the present disclosure, the mounting seat has a threaded portion for mounting the electrical device. The threaded portion preferably includes a male thread or a female thread.

[0015] [6] In the work vehicle of the present disclosure, it is preferable that the mounting seat is attached to the canopy pole by welding.

[0016] [7] In the work vehicle of the present disclosure, the electrical equipment is preferably a beacon lamp or a light. [Effects of the Invention]

[0017] The work vehicle of the present invention includes a bracket disposed to the side of the operator seat and a power socket supported by the bracket. The power socket's insertion port is disposed so as to face the rear of the work vehicle. By arranging the power socket's insertion port so as to face the rear of the work vehicle, when a plug for an electrical device is inserted into the insertion port, the electrical wiring connected to the plug is disposed from a position to the side of the operator seat toward the rear of the work vehicle.

[0018] As a result, when an operator gets on or off the work vehicle, the electrical wiring can be prevented from interfering with the operator's ability to get on or off. Also, when the operator operates the work vehicle, the electrical wiring can be prevented from interfering with the operator and hindering operation.

[0019] In other words, the work vehicle of the present invention can provide a work vehicle that can prevent plugs and electrical wiring connected to power sockets from being placed in places where operators get on and off or where machine operation is performed.

[0021] Hereinafter, modes for carrying out the present invention (hereinafter referred to as "embodiments") will be described. The embodiments described below show preferred modes for carrying out the invention, and do not limit the invention according to the claims. Furthermore, not all of the elements and combinations thereof described in the embodiments are necessarily essential to the present invention.

[0022] 1. Work vehicles A work vehicle 1 according to an embodiment of the present invention will be described below with reference to the drawings. In the embodiment described below, a crawler hydraulic excavator will be described as an example of the work vehicle 1. First, the external configuration of the work vehicle 1 according to the embodiment will be described with reference to Figures 1 and 2. Note that the external configuration of the work vehicle 1 according to the embodiment is not the gist of the present invention, so only a general description will be given.

[0023] Furthermore, when it is necessary to indicate the left and right, front and rear, and top and bottom of the work vehicle 1 when explaining the work vehicle 1 according to the embodiment, the side of the work vehicle 1 on which the blade 30 is attached will be referred to as the "front", and the side opposite to the side on which the blade 30 is attached will be referred to as the "rear". Furthermore, the left side of the work vehicle 1 when viewed from behind will be referred to as the "left", and the right side of the work vehicle 1 when viewed from behind will be referred to as the "right". Furthermore, the bottom side of the work vehicle 1 will be referred to as the "bottom", and the side opposite the bottom will be referred to as the "top".

[0024] Fig. 1 is a diagram shown to explain a work vehicle 1 according to an embodiment, and is an external perspective view of the work vehicle 1 as seen diagonally from the front. Fig. 2 is a diagram shown to explain a work vehicle 1 according to an embodiment, and is an external perspective view of the work vehicle 1 as seen diagonally from the rear. Note that in Fig. 2, the undercarriage 10, blade 30, and working implement 40 are omitted from illustration.

[0025] As shown in Figure 1, the work vehicle 1 comprises a lower running body 10, an upper rotating body 20 rotatably mounted on the upper part of the lower running body 10, a blade 30 mounted on the front part of the lower running body 10, and a work device 40 mounted on the front part of the upper rotating body 20.

[0026] The lower traveling body 10 has a pair of left and right crawlers 12 on both the left and right sides of a frame 11. A blade 30 that is capable of swinging up and down is attached to the frame 11. A swivel mechanism (not shown) is provided at approximately the center of the upper part of the frame 11. The swivel mechanism allows the upper rotating body 20 to rotate on a horizontal plane. The lower traveling body 10, upper rotating body 20, blade 30, and working device 40 are each driven by a corresponding hydraulic actuator (hydraulic motor, hydraulic cylinder, etc.).

[0027] The top, rear, left side, right side, and front of the upper rotating body 20 are each covered with a cover. The area covered by the covers forms an equipment housing chamber (reference numeral omitted). Here, the covers covering the top and rear of the equipment housing chamber are referred to as a battery cover 22, and the covers covering the left side, right side, and front are referred to as a left side cover 23, a right side cover 24 (see FIG. 2), and a front cover 25, respectively.

[0028] A canopy-type operator's cab 50 is provided above the equipment storage room. The operator's cab 50 is provided with a canopy pole 61, an operator's seat 52, and an operating lever 53. A counterweight 29 (see FIG. 2) that forms part of the rear surface is provided below the rear surface of the upper rotating body 20. The canopy pole 61 will be described later.

[0029] 2. Power socket 2 and 3, the work vehicle 1 is provided with a power socket 54 and a bracket 57. Figure 3 is a diagram shown to explain the power socket 54 provided on the work vehicle 1 according to the embodiment.

[0030] The brackets 57 are disposed on the sides of the operator seat 52. In the work vehicle 1 according to this embodiment, the brackets 57 are disposed on the left and right sides of the operator seat 52, respectively.

[0031] The bracket 57 disposed on the left side of the operator seat 52 stands upright on a console 59 provided on the battery cover 22. The bracket 57 disposed on the right side of the operator seat 52 stands upright on a console 59 provided on the battery cover 22.

[0032] Bracket 57 may be erected and fixed by some means to work vehicle 1. There are no particular limitations on the position at which bracket 57 is erected, as long as it is on the side of operator seat 52. Bracket 57 may be erected, for example, on the side of operator seat 52, from battery cover 22, left side cover 23, or right side cover 24.

[0033] The power socket 54 is disposed to the side of the operator seat 52. The power socket 54 is supported by a bracket 57. The power socket 54 has an insertion opening 54a into which a plug (not shown) of an electrical device is inserted. The insertion opening 54a is disposed facing rearward relative to the work vehicle 1.

[0034] As a result, when a plug (not shown) is inserted into the insertion opening 54a, the electrical wiring (not shown) connected to the plug is arranged facing towards the rear of the work vehicle 1. As a result, it is possible to prevent the electrical wiring from interfering with the operator when getting on or off the work vehicle 1. It is also possible to prevent the electrical wiring from interfering with the operator when operating the work vehicle 1, thereby hindering operation.

[0035] Note that "the insertion port 54a is positioned facing rearward relative to the work vehicle 1" means that the insertion port 54a is positioned so that when a plug is inserted into the insertion port 54a, the electrical wiring connected to the plug extends rearward.

[0036] Therefore, it is not necessary that the insertion opening 54a be positioned so as to face rearward in the strict sense with respect to the work vehicle 1. For example, the insertion opening 54a may be positioned so as to be inclined toward the operator seat 52, or so as to be inclined toward the outside of the work vehicle 1.

[0037] In a configuration in which the insertion opening 54a is disposed at an angle toward the operator seat 52, there is an advantage that it becomes easier for the operator seated in the operator seat 52 to insert and remove a plug into and from the insertion opening 54a. On the other hand, in a configuration in which the insertion opening 54a is disposed at an angle toward the outside of the work vehicle 1, the electrical wiring passes through a position away from the operator seat 52, further reducing the possibility of interference between the operator and the electrical wiring.

[0038] Here, "electrical equipment" includes all equipment that is attached to and used on the work vehicle 1 and that operates on electricity. An example of electrical equipment is a light. The electrical equipment is preferably a beacon light that indicates that the work vehicle 1 is in operation, or a light that functions as an illumination.

[0039] In a preferred embodiment, the power sockets 54 are located on the left and right sides of the operator seat 52. The work vehicle 1 according to this embodiment is equipped with a left power socket 54 located on the left side of the operator seat 52 and a right power socket 54 located on the right side of the operator seat 52.

[0040] This allows a user to use two or more electrical devices at the same time by supplying power to some of the electrical devices from the left power socket 54 and to supply power to other electrical devices from the right power socket 54.

[0041] Furthermore, even when power sockets 54 are provided on both the left and right sides of the work vehicle 1, the insertion openings 54a of the left power socket 54 and the right power socket 54 are provided so as to face rearward relative to the work vehicle 1. Therefore, the electrical wiring connected to the plugs is provided facing toward the rear of the work vehicle 1. This makes it possible to prevent the plugs and electrical wiring connected to the power sockets 54 from being provided in areas where the operator gets in and out of the vehicle or where machine operation is performed.

[0042] Furthermore, when there is only one electrical device to be powered, power can be supplied from either the left or right power socket 54, whichever is closer to the electrical device, thereby shortening the length of the electrical wiring routed inside the work vehicle 1 and preventing the plugs and electrical wiring connected to the power socket 54 from being placed in areas where the operator gets in and out of the vehicle or where machine operation is performed.

[0043] In this way, by including a right-side power socket 54 located on the right side of the operator seat 52 and a left-side power socket 54 located on the left side of the operator seat 52, it is possible to realize a power supply method that meets a variety of user needs while preventing plugs and electrical wiring connected to the power sockets 54 from being placed in places where the operator gets on and off or where the machine is operated.

[0044] Power socket 54 includes lid 55. Lid 55 is a lid for covering insertion opening 54a when power socket 54 is not in use. By covering insertion opening 54a with lid 55, it is possible to prevent water such as rain, sand, or dust from entering power socket 54 and causing damage to power socket 54.

[0045] The work vehicle 1 is equipped with armrests 58. The armrests 58 are located on the left and right sides of the operator seat 52. The armrests 58 are located behind the operating levers 53 on the work vehicle 1. The operator can operate the operating levers 53 with his or her arms placed on the armrests 58 and accurately steer the work vehicle 1.

[0046] Armrest 58 is supported by bracket 57. Armrest 58 is also disposed above power socket 54. By employing such a configuration, interference between the operator and power socket 54 when the operator operates work vehicle 1 can be suppressed. Interference between the operator and electrical wiring can also be suppressed. Furthermore, rain can be prevented from directly falling on power socket 54.

[0047] 3. Mounting base for electrical equipment As shown in Fig. 2, the work vehicle 1 is provided with a canopy pole 61 and a mounting seat 62 for electrical equipment. In the following description, the "mounting seat 62 for electrical equipment" will be simply referred to as the "mounting seat 62".

[0048] The canopy pole 61 is also called a "rollover protection structure" and has the role of protecting the operator when the work vehicle 1 rolls over. The canopy pole 61 includes a pillar portion 61a extending upward from the main body frame (not shown) of the work vehicle 1, a first beam portion 61b extending in the front-to-rear direction of the work vehicle 1, a second beam portion 61c extending in the vehicle width direction of the work vehicle 1, a first bent portion 61d connecting the pillar portion 61a and the first beam portion 61b, and a second bent portion 61e connecting the first beam portion 61b and the second beam portion 61c.

[0049] The work vehicle 1 according to this embodiment has pillar portions 61a erected from each of the left and right rear ends of the work vehicle 1. That is, the canopy pole 61 provided on the work vehicle 1 has two pillar portions 61a. The two pillar portions 61a are each connected to a first beam portion 61b via a first bent portion 61d at a position at a predetermined height.

[0050] The pillar portion 61a and the first beam portion 61b are connected at the first bent portion 61d so that they extend in different directions. The pillar portion 61a and the first beam portion 61b may be formed by bending a pole, as shown in Figures 1 and 2. Alternatively, the pillar portion 61a and the first beam portion 61b may be connected by means of welding or the like so that the extending direction of the pillar portion 61a and the extending direction of the first beam portion 61b are different.

[0051] When the work vehicle 1 is viewed from above, the first beam portion 61b extends from the rear to the front of the work vehicle 1 at the left end position of the cab 50 or the right end position of the cab 50. The end of the first beam portion 61b on the front side of the work vehicle 1 is connected to one of the two ends of the second beam portion 61c.

[0052] The mounting seats 62 are installed on the first beam portion 61b of the canopy pole 61. In the work vehicle 1 according to this embodiment, two mounting seats 62 are installed on the first beam portion 61b.

[0053] There are no particular limitations on the location where the mounting seat 62 is installed. Depending on the type of electrical appliance to be installed, the mounting seat 62 can be provided on the left first beam portion 61b, the right first beam portion 61b, or both the left first beam portion 61b and the right first beam portion 61b. There is also no limit on the number of mounting seats 62 that can be installed.

[0054] It is preferable that mounting seat 62 is located on first beam portion 61b, and is located inside the vehicle width of work vehicle 1 when viewed from above. This makes it possible to prevent the turning radius of work vehicle 1 from becoming too large.

[0055] Furthermore, if the cab 50 is biased to the left or right side of the work vehicle 1, it is preferable to install the mounting seat 62 on the first beam portion 61b that is located in a position close to the center of rotation (not shown) of the upper rotating body 20. This makes it possible to prevent the turning radius of the work vehicle 1 from becoming too large.

[0056] The mounting seat 62 may have any shape as long as it is capable of mounting an electrical device. The mounting seat 62 may have a threaded portion for mounting the electrical device. The threaded portion is preferably a male or female thread.

[0057] 2 shows an example of the mounting seat 62. The mounting seat 62 has a cylindrical outer shape. One bottom surface of the cylinder is fixed to the first beam portion 61b by welding. The other bottom surface has a female thread formed thereon that extends in the height direction of the cylinder.

[0058] Other examples of the mounting seat 62 include a mounting seat having an outer shape of a polygonal prism such as a square prism or a hexagonal prism, with a female thread formed in the height direction of the polygonal outer shape. Other examples include a mounting seat in which a female thread is formed in a rectangular plate, and a mounting seat in which the above-mentioned rectangular plate has legs and is welded to the first beam portion 61b via the legs.

[0059] Further, examples of other forms of the mounting seat 62 include a mounting seat in which a bolt or nut is welded to a plate, and a mounting seat in which a bolt or nut is directly welded to the first beam portion 61b.

[0060] By providing the mounting seat 62 as described above, when a user wants to secure an electrical device such as a beacon lamp to the work vehicle 1, the user can easily secure the electrical device using the mounting seat 62. In other words, the electrical device can be secured to the mounting seat 62 without using complicated means such as welding. This makes it easy to secure and detach electrical devices to and from the canopy pole 61.

[0061] Furthermore, if the mounting seat 62 has a threaded portion for attaching an electrical device, the threaded portion can be used to easily fasten the electrical device to the canopy pole 61. If the threaded portion is a male thread, the electrical device can be fastened using a nut. If the threaded portion is a female thread, the electrical device can be fastened using a bolt.

[0062] The effects achieved by the work vehicle 1 according to this embodiment will be described below.

[0063] [1] The work vehicle 1 according to the embodiment includes a bracket 57 disposed on the side of the operator seat 52, and a power socket 54 supported by the bracket 57. An insertion port 54a of the power socket 54 is disposed so as to face the rear of the work vehicle 1.

[0064] As a result, when an electrical device plug is inserted into insertion port 54a of power socket 54, the electrical wiring connected to the plug is arranged from a position to the side of operator seat 52 toward the rear of work vehicle 1. As a result, it is possible to prevent the electrical wiring from interfering with the operator when getting on or off the work vehicle 1. It is also possible to prevent the electrical wiring from interfering with the operator when operating the work vehicle 1, thereby hindering operation.

[0065] According to the work vehicle 1 of the embodiment, it is possible to provide a work vehicle 1 that can prevent plugs and electrical wiring connected to the power socket 54 from being placed in places where operators get on and off or where machine operation is performed.

[0066] The work vehicle 1 according to this embodiment further includes an armrest 58. The armrest 58 is disposed above the bracket 57. This makes it possible to prevent interference between the operator and the power socket 54 when the operator operates the work vehicle 1. It also makes it possible to prevent interference between the operator and the electrical wiring.

[0067] [3] In the work vehicle 1 according to the embodiment, the power sockets 54 include a right-side power socket 54 located on the right side of the operator seat 52 and a left-side power socket 54 located on the left side of the operator seat 52.

[0068] As a result, when a user uses two or more electrical devices simultaneously, some of the electrical devices can be powered from the left power socket 54, and the other electrical devices can be powered from the right power socket 54. Furthermore, if only one electrical device needs to be powered, power can be supplied from either the left power socket 54 or the right power socket 54, whichever is closest to the electrical device. In other words, the work vehicle 1 according to this embodiment makes it possible to realize a power supply method that meets a variety of user needs, while preventing plugs and electrical wiring connected to the power sockets 54 from being placed in places where the operator gets in and out of the vehicle or where the operator operates the machine.

[0069] [4] The work vehicle 1 according to the embodiment further includes a canopy pole 61 erected behind the operator seat 52, and a mounting seat 62 disposed on the canopy pole 61 for mounting electrical equipment. This allows the user to secure electrical equipment to the work vehicle 1 without using complicated means such as welding, making it easy to secure and remove electrical equipment from the canopy pole 61.

[0070] [5] In the work vehicle 1 according to this embodiment, the mounting seat 62 has a threaded portion for attaching electrical equipment, and the threaded portion includes a male thread or a female thread. This allows the electrical equipment to be easily attached to the mounting seat 62 using a nut that engages with the male thread or a bolt that engages with the female thread.

[0071] [6] In the work vehicle 1 according to the embodiment, the mounting seat 62 is attached to the canopy pole 61 by welding. This allows the mounting seat 62 to be firmly attached to the canopy pole 61.

[0072] [7] In the work vehicle 1 according to the embodiment, the electrical equipment is a beacon lamp or a light. By having the work vehicle 1 have a beacon lamp or a light as electrical equipment, the safety and efficiency of work performed by the work vehicle 1 can be improved.

[0073] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0074] For example, in the above-described embodiment, the work vehicle 1 is used in which the lower traveling body 10 uses the crawler 12 as the traveling device, but the present invention is not limited to this. For example, the work vehicle 1 may use tires as the traveling device. [Explanation of symbols]
