Description

  The present invention relates to a housing, and more particularly, to a housing including a lock mechanism and an industrial vehicle including the housing.

  In general, an industrial vehicle such as a hydraulic excavator or a wheel loader includes a housing that houses various devices such as a battery, an engine, a hydraulic pump, and a valve device. Such industrial vehicles are required to prevent rattling of the open / close cover because vibration occurs during travel and work. On the other hand, for example, Patent Document 1 is a structure for fixing an opening / closing cover provided on a construction machine to a storage box, and in addition to a well-known locking mechanism, a conical shape provided on the opening / closing cover side. There has been proposed a structure including a stopper and a grommet provided on the storage box side in which the stopper is inserted (see FIG. 3 of Patent Document 1). According to the above configuration, when the open / close cover is closed, the open / close cover is fitted to the grommet and the open / close cover is elastically held by the building cover. In addition, the door can be closed with a light force without deforming the opening / closing cover.

JP 2000-64348 A

  However, in the open / close cover described in Patent Document 1, consideration is given to preventing rattling of the open / close cover due to vibrations generated when the construction machine is traveling or working, but an external force greater than such vibrations acts on the open / close cover. No consideration is given to such cases.

  For example, when a separate structure is attached to the outer surface of the opening / closing cover, or when the opening / closing cover itself is very heavy, a large force may be applied to the opening / closing cover. In such a case, the open / close cover described in Patent Document 1 has a problem that it is not sufficiently fixed and rattling occurs. It is conceivable to lock firmly against such problems, but in such a case, it may be possible to provide a plurality of fixing devices on one open / close cover or increase the size of the fixing structure. However, there is a problem that the cost increases and the burden on the worker due to the fixing work of the opening / closing cover increases. Further, the open / close cover described in Patent Document 1 is fixed by fitting, so that there is a problem that improvement of component accuracy is required and position adjustment of each component is required.

  An object of this invention is to provide the housing | casing provided with the fixing structure which can be locked easily and firmly in view of the above situations.

  A casing according to an aspect of the present invention includes a casing main body having an opening formed on a front surface, a first rotation shaft, an opening / closing cover that opens and closes the opening of the casing main body, and a second A fixing cover that covers at least a part of the front surface of the opening / closing cover when the door is closed; and a force is applied to the fixing cover in a direction toward the opening / closing cover when the door is closed; A locking mechanism that locks the opening / closing cover, the fixing cover, and the housing body; and between the opening / closing cover and the fixing cover when the door is closed, and the locking mechanism and the second rotating shaft; And a contact member that contacts each of the opening / closing cover and the fixing cover.

  According to such a configuration, since the contact member is located between the lock mechanism and the rotation shaft of the fixing cover, when the force is applied to the fixing cover by the lock mechanism, even if the force is small, the contact is made. The opening / closing cover can be strongly pressed against the casing body via the member. Needless to say, when the force applied by the lock mechanism is small, it is easier to fix the opening / closing cover than when a large force is required.

  As described above, the housing according to the present invention can be easily and firmly locked.

As shown in FIGS. 1 to 3, the housing 100 according to the present embodiment includes a housing body 10, an opening / closing cover 30, a fixing cover 50, and a lock mechanism 70. Hereinafter, each of these components will be described in order. After that, the operation of these components will be described.

<Case body>
The housing body 10 is a member to which the opening / closing cover 30 or the like is attached. FIG. 4 is an overall view of the industrial vehicle 101 to which the housing body 10 according to the present embodiment is attached. As shown in FIG. 4, the housing body 10 according to the present embodiment is attached to the lower side of the driver's seat 102 of the industrial vehicle 101. The industrial vehicle 101 according to the present embodiment is a wheel loader, for example, a construction vehicle such as a bulldozer or a hydraulic excavator provided with a storage box for storing various devices, another industrial vehicle such as a tank truck or a fire truck, Various vehicles such as railway vehicles are included. In the present embodiment, the housing body 10 constitutes a battery box of the industrial vehicle 101 in combination with an opening / closing cover 30 described later. This battery box accommodates a battery (not shown) inside, but in addition to that, a step 103 for climbing to the driver's seat 102 is provided on the outer surface. That is, this battery box is located behind the step 103 of the industrial vehicle 101, and effectively uses a portion that has been a conventional dead space as a battery storage space.

  As shown in FIG. 3, the housing body 10 has a box shape, a back surface portion 11 attached to the vehicle body of the industrial vehicle 101, a front surface portion 12 facing the inner surface of the back surface portion, A right side surface portion 13 positioned on the right side when viewing the back surface portion 11 from the front surface portion 12, a left side surface portion 14 positioned on the left side when viewing the back surface portion 11 from the front surface portion 12, and a bottom surface portion 15 positioned below the housing body 10, And an upper surface portion 16 located above the housing body 10.

  Among these, the front part 12 is smaller in height than the back part 11, the right side part 13, and the left side part 14, and the top part 16 is greatly cut away on the back part 11 side. That is, the housing body 10 has a part of the front surface and a part of the upper surface opened to form the opening 17. Here, when viewed from the center of the housing body 10, the front portion 12 side is defined as the front (the same applies hereinafter). Then, the front edge portion of the right side surface portion 13, the front edge portion of the left side surface portion 14, the front edge portion of the upper surface portion 16, and the upper edge portion of the front surface portion 12 constitute the outer edge of the opening portion 17. The operator accesses the battery housed inside through the opening 17.

  Further, the front edge portion of the right side surface portion 13 is divided into upper and lower portions to constitute a support portion 18 on a line. As will be described later, the opening / closing cover 30 is fixed in a state of being pressed against the support portion 18. Further, the housing body 10 has a first contact member 19 in the vicinity of the right side surface portion 13 in the upper edge portion of the front portion 12 (lower edge portion of the opening portion 17). The first contact member 19 has an L-shaped cross section (see FIG. 7), and the upper surface 20 is formed flat. As will be described later, when the opening / closing cover 30 is closed, the second contact member 36 (see FIG. 7) of the opening / closing cover 30 rides on the upper surface 20. Further, a lowermost step plate 104 of step 103 is attached to the outer surface of the front portion 12.

<Opening and closing cover>
The opening / closing cover 30 is a member that covers the opening 17 of the housing body 10. As shown in FIG. 2, the open / close cover 30 includes a front plate 31 that covers the front side of the opening 17 and an upper surface plate 32 that covers the upper surface of the opening 17. The front plate 31 is L-shaped in cross section and has a plate shape. The upper surface plate 32 has a flat plate shape. The front plate 31 is on the right side surface 13 side (front end side), and a part of the central portion in the vertical direction is cut away. Further, the front plate 31 is provided with three tread plates 104 which are part of the step 103 on the outer surface. This step 103 is used for the worker to ascend to the driver seat 102 of the industrial vehicle 101 and to get out of the driver seat 102. Therefore, a large force is applied to the opening / closing cover 30 by the operator getting on the step 103. For this reason, the casing 100 according to the present embodiment for fixing the opening / closing cover 30 needs to have high strength.

  FIG. 5 is a schematic front view of the housing 100 according to the present embodiment. FIG. 6 is a schematic horizontal sectional view of the housing 100 according to the present embodiment. In FIG. 5 and FIG. 6, step 103 is deleted. As shown in FIGS. 5 and 6, the opening / closing cover 30 is rotatably supported by the two first support members 33 on the left side surface portion 14 side (base end side). The first support member 33 is a so-called hinge, and one side of the first support member 33 is attached to the left side surface portion 14 of the casing body 10 with the shaft 34 interposed therebetween, and the other side is attached to the front plate 31 of the opening / closing cover 30. It is attached. Thereby, the opening / closing cover 30 rotates about the shaft bar 34 of the first support member 33 as the first rotation shaft. The first support member 33 is disposed such that the first rotation shaft (shaft bar 34) extends in the vertical direction. In the present embodiment, the first rotation shaft (shaft bar 34) of the first support member 33 is provided so as to extend vertically obliquely.

  In addition, as shown in FIG. 2, the opening / closing cover 30 is provided at two locations on the upper side and the lower side in the vicinity of the distal end (the right half region and the left half region when viewing the distal end side from the proximal end side of the opening / closing cover 30). It has a disk-shaped contact member 35 protruding in the direction. However, the contact member 35 may have other shapes such as a hemispherical shape or a conical shape. The contact member 35 according to this embodiment is made of metal and has high rigidity. However, the contact member 35 may be formed of rubber or resin. As will be described later, the contact member 35 is a portion in contact with the fixing cover 50 and a portion to which a force is applied from the fixing cover 50. Therefore, by disposing the contact members 35 at the two positions, a force is applied to a wide range of the front end portion of the opening / closing cover 30 to prevent the opening / closing cover 30 from being distorted and partially opening the front end portion. be able to.

  As shown in FIG. 6, the support portion 18 of the housing body 10 is located on the back side of the contact member 35. That is, the contact member 35 is disposed at a position corresponding to the support portion 18 of the housing body 10. By arranging in this way, the support portion 18 is positioned on the direction line of the force applied from the fixing cover 50 to the contact member 35. Therefore, the support portion 18 can firmly support the opening / closing cover 30 that receives a force via the contact member 35.

  As shown in FIG. 3, the opening / closing cover 30 has a second contact member 36 near the lower end of the inner surface. The lower surface 37 of the second contact member 36 is formed flat. Here, FIG. 7 is a diagram showing a positional relationship between the first contact member 19 of the housing body 10 and the second contact member 36 of the opening / closing cover 30 described above. The left diagram in FIG. 7 shows a state when the opening / closing cover 30 is slightly opened. Moreover, the figure on the right side shows a state when the opening / closing cover 30 is completely closed. As shown in FIG. 7, the upper surface 20 of the first contact member 19 is located on the same plane as the lower surface 37 of the second contact member 36 or slightly above it in the vertical direction. For this reason, when the opening / closing cover 30 is shifted from a slightly opened state (left diagram) to a completely closed state (right diagram), the second contact member 36 rides on the first contact member 19. Thus, when the second contact member 36 rides on the first contact member 19, the movement of the open / close cover 30 in the vertical direction is restricted. As a result, the vertical displacement of the opening / closing cover 30 can be suppressed.

<Fixing cover>
The fixing cover 50 is a member that overlaps the surface near the tip of the opening / closing cover 30. As shown in FIGS. 3 and 6, the fixing cover 50 according to the present embodiment has a plate shape and an L-shaped cross section. The right cover 13 side (base end side) of the fixing cover 50 is rotatably supported by two second support members 51. The second support member 51 is a so-called hinge and has substantially the same configuration as the first support member 33 that supports the opening / closing cover 30. As shown in FIG. 6, one side of the second support member 51 with the shaft 52 interposed therebetween is attached to the right side surface portion 13 of the housing body 10, and the other side is attached to the fixing cover 50. . Accordingly, the fixing cover 50 rotates with the shaft rod 52 of the second support member 51 as the second rotation shaft. Further, as shown in FIG. 3, the second support member 51 is configured such that the second rotation shaft (shaft bar 52) is inclined slightly rearward (on the back surface 11 side of the housing body 10) with respect to the vertical direction. It arrange | positions so that it may extend.

  As shown in FIG. 5, the fixing cover 50 is formed with a window portion 53 near the center. An engaging member 71 of a lock mechanism 70 described later is attached near the lower edge of the window portion 53 of the fixing cover 50. Further, when the opening / closing cover 30 is in a closed state, the window portion 53 is located at a position corresponding to a notched portion of the opening / closing cover 30. The reason for this arrangement is to allow a part of the lock mechanism 70 to pass through the window 53 of the fixing cover 50 and the notched portion of the opening / closing cover 30 as will be described later. . As shown by the black circles in FIG. 6, the fixing cover 50 has a biasing portion 54 that is a portion to which a force is applied from the lock mechanism 70. The urging portion 54 is located near the center of the fixing cover 50 to which the engaging member 71 is attached. The fixing cover 50 also has a contact portion 55 that is a portion that contacts the open / close cover 30 as indicated by the black circles in FIG. In the present embodiment, since the fixing cover 50 is in contact with the opening / closing cover 30 by the contact member 35, the two portions that are in contact with the contact member 35 are the contact portions 55.

<Lock mechanism>
The lock mechanism 70 is a mechanism that locks the fixing cover 50, the opening / closing cover 30, and the housing body 10. The lock mechanism 70 according to the present embodiment mainly includes an engaging member 71 provided on the fixing cover 50 and an engaged member 72 provided on the housing body 10.

  As described above, the engaging member 71 is attached near the lower edge of the window portion 53 formed in the fixing cover 50. As shown in FIG. 2, the engaging member 71 is mainly configured by a lever 73 and an engaging ring 74. FIG. 8 is a schematic side view of the lock mechanism 70. In FIG. 8, the direction perpendicular to the paper surface is the horizontal direction. As shown in FIG. 8, the lever 73 is configured to be rotatable about a support shaft member 75 that is fixed to the fixing cover 50 and extends in the horizontal direction as a rotation axis. The engagement ring 74 has a ring shape that is rectangular as a whole. The lever 73 is formed with a holding hole 76 at a position away from the support shaft member 75. The holding hole 76 is formed to extend in the horizontal direction. The engagement ring 74 is inserted into the holding hole 76 and is configured to be rotatable about the center of the holding hole 76 as a rotation axis.

  As shown in FIG. 3, the engaged member 72 is attached in the vicinity of the front edge of the right side surface portion 13 of the housing body 10. As shown in FIG. 8, the engaged member 72 is formed with an engaged groove 77 that opens rearward (right side of the drawing). The engaged groove 77 is configured to be able to engage the engagement ring 74 of the engagement member 71. As shown in FIG. 6 and the like, when the engagement ring 74 is engaged with the engaged groove 77, the engagement ring 74 is notched in the window portion 53 of the fixing cover 50 and the opening and closing cover 30 ( 5) and is engaged with the engaged groove 77.

  Since the lock mechanism 70 has the above-described configuration, as shown in FIG. 8, the engagement ring 74 is engaged with the engaged groove 77, and in this state, the support shaft member 75 is used as the rotation shaft. When the lever 73 is rotated downward (counterclockwise in FIG. 8), a force to pull the engaged member 72 forward is applied to the engaged member 72 via the engaging ring 74. On the contrary, a force in the backward direction is applied to the engaging member 71 by the reaction force of the force with which the engaging member 71 pulls the engaged member 72. Therefore, a biasing force is applied to the fixing cover 50 so as to push it from the engagement member 71 to the rear side (opening / closing cover 30 side). Actually, since the engaged member 72 is fixed to the housing body 10, it does not move, and the fixing cover 50 (and the opening / closing cover 30) slightly moves toward the housing body 10. As described above, the lock mechanism 70 according to the present embodiment employs a configuration using a reaction force to generate a large urging force even though the occupied space is small.

  Further, the lock mechanism 70 is arranged as follows in relation to the contact member 35. That is, as shown in FIG. 6, when the opening / closing cover 30 is closed, the lock mechanism 70 is located farther from the second support member 51 (second rotation shaft of the fixing cover 50) than the contact member 35. Has been placed. In other words, the contact member 35 is located between the lock mechanism 70 and the second rotation shaft of the fixing cover 50. Therefore, the distance from the second rotation shaft of the fixing cover 50 to the biasing portion 54 is larger than the distance from the second rotation shaft of the fixing cover 50 to the contact portion 55. Here, the “distance” refers to a distance on a plane orthogonal to the direction in which the urging force works.

<Operation of the housing>
Since the housing 100 according to the present embodiment has the above-described configuration, the housing 100 operates as follows when the cover 30 is fixed. FIG. 9 is a schematic diagram showing the positional relationship between the urging portion 54 and the contact portion 55 according to the present embodiment. As shown in FIG. 6 and the like, both of the opening / closing cover 30 and the fixing cover 50 are formed in an L-shaped cross section. However, in FIG. It is shown. That is, FIG. 9 is not intended to limit the present invention only when the opening / closing cover 30 and the fixing cover 50 are flat. As shown in FIG. 9, the distance X from the second support member 51 (the rotation shaft of the fixing cover 50) to the urging portion 54 is larger than the distance Y from the second support member 51 to the contact portion 55. In terms of mechanics, it can be considered that the second support member 51 is a fulcrum, the urging portion 54 is a power point, and the contact portion 55 is an action point.

  Therefore, when the operator operates the lever 73 and applies a force to the urging portion 54 by the lock mechanism 70, a force larger than the force applied to the urging portion 54 is applied to the contact portion 55. That is, the force applied to the urging portion 54 by the lock mechanism 70 is increased at the contact portion 55, and the opening / closing cover 30 can be strongly pressed against the housing body 10 via the contact portion 55. Therefore, according to the casing 100 according to the present embodiment, the opening / closing cover 30 is pressed against the casing body 10 with a strong force and fixed firmly while being an easy fixing operation of operating one lever 73. Can do.

  Further, the lock mechanism 70 according to the present embodiment is configured such that the engagement member 71 and the engaged member 72 are engaged, and the opening / closing cover 30, the fixing cover 50, and the housing body 10 are locked. Therefore, the open / close cover 30, the fixing cover 50, and the housing body 10 can be firmly locked despite the small occupied space. In the present embodiment, the lock mechanism 70 is provided at a substantially central position of the opening / closing cover 30 and the housing body 10 in the vertical direction, and the contact member 35 is provided in the vertical direction. Since the force is applied to a wide range of the front end portion of the opening / closing cover 30 and the opening / closing cover 30 is distorted, a part of the front end portion can be prevented from being opened.

  Further, in the present embodiment, the casing body 10 has the first contact member 20 at the lower end of the opening 17, and the opening / closing cover 30 contacts the first contact member 20, so that the opening / closing cover 30 is Since it has the 2nd contact member 36 which gets on the lower end part of the body main body 10 and is closed, the displacement to the vertical direction of the opening-and-closing cover 30 can be suppressed.

  The housing body 10 according to the present embodiment is a storage box that is provided below the side surface of the driver's seat 102 of the industrial vehicle 101 and can store equipment. The opening / closing cover 30 has an operator getting on and off the front surface thereof. A step 103 is attached. Therefore, the portion on the back side of the step, which has been a dead space in the past, can be effectively used as the accommodation space.
