[0001] The present application relates to a locking mechanism of a storage box. BACKGROUND

[0002] In the past, a storage box device provided with a locking mechanism capable of releasing fixation of a locking pin of a cover member by a turning action of a cam member is known (for example, refer to Patent Document 1). Such a storage box device has a link mechanism that enables the cam member to turn, and by releasing engagement of the link mechanism, the cam member is rendered unable to turn and is locked.

[0003] PRIOR ART DOCUMENTS

[0004] Patent Document 1: Japanese Patent Application Laid-Open No. 62-146379 SUMMARY

[0005] PROBLEMS TO BE SOLVED BY THE INVENTION

[0006] However, in the prior art, there is a problem in that the number of components of the link mechanism is large and the action is complicated.

[0007] MEANS FOR SOLVING THE PROBLEMS

[0008] A locking mechanism of a storage box capable of releasing fixation of a locking pin of a cover member by a turning action of a cam member is characterized in that the locking mechanism of the storage box is provided with a cam support member that supports the cam member, and a turning lock plate that restricts turning of the cam member, the turning lock plate restricting turning of the cam member when positioned at a position along an abutting portion provided to the cam support member.

[0009] EFFECTS OF THE INVENTION

[0010] In the case of restricting turning of the cam member, the turning lock plate only needs to be moved to a position in contact with the cam member. Therefore, a link mechanism is not required, the number of components is reduced, and the configuration is simplified.

[0011] Further, even in the case where a large force is applied to the cam member, turning restriction of the action of the cam member is performed by cooperation of the turning lock plate and the abutting portion of the cam support member, and therefore, the strength of the turning lock plate is enhanced.

[0047] The front fork 14 is supported by the front stand pipe 18 to be steered left and right. The front wheel 13 is supported to an axle 13a provided at the lower end portion of the front fork 14. A handle 21 for steering which is held by the occupant is mounted to the upper end portion of the front fork 14.

[0048] The swing arm 16 is supported by a pivot shaft 22 supported to the vehicle frame 11. The pivot shaft 22 is a shaft which extends horizontally in the vehicle width direction. The pivot shaft 22 is inserted through the front end portion of the swing arm 16. The swing arm 16 swings up and down about the pivot shaft 22 as a center.

[0049] The rear wheel 15 is supported to an axle 15a provided at the rear end portion of the swing arm 16.

[0050] The power unit 12 is disposed between the front wheel 13 and the rear wheel 15, and is supported to the vehicle frame 11.

[0051] The power unit 12 is an internal combustion engine. The power unit 12 is provided with a crankcase 23 and a cylinder portion 24 which houses a reciprocating piston. An exhaust port of the cylinder portion 24 is connected to an exhaust device 25.

[0052] The output of the power unit 12 is transmitted to the rear wheel 15 through a drive force transmission member that connects the power unit 12 and the rear wheel 15.

[0053] In addition, the straddle-type vehicle 10 has a front fender 26 that covers the front wheel 13 from above, a rear fender 27 that covers the rear wheel 15 from above, a step 28 for a passenger to put his feet on, and a fuel tank 29 that stores fuel used by the power unit 12.

[0054] The front fender 26 is mounted to the front fork 14. The rear fender 27 and the step 28 are provided at positions lower than the seat 17. The fuel tank 29 is supported to the vehicle frame 11.

[0055] The straddle-type vehicle 10 is provided with storage boxes 30 at the rear of the vehicle.

[0056] Figure 2 is a perspective view of the storage box 30, Figure 3 is a vertical sectional view in the front-rear direction of the storage box 30.

[0057] A pair of the storage boxes 30 are mounted to the left and right side surfaces of the vehicle frame 11 via tubular mounting members 31.

[0058] The storage boxes 30 on the left and right are identical in construction, and therefore, the storage box 30 mounted to the right side surface will be described, and as for the storage box 30 mounted to the left side surface, the same parts will be designated by the same reference numerals and the description thereof will be omitted.

[0059] The storage box 30 is provided with a lid member 40 and a box-shaped case 51 that is open at the top. As shown in Figure 3 , the lid member 40 is linked to the front portion of the case 51 by a hinge 33, and the lid member 40 is opened by lifting the rear portion 40a of the lid member 40. The hinge 33 is covered from the rear by a cover 35. The lid member 40 is limited in the movable range by the cover 35 so as not to be opened excessively.

[0060] A lock mechanism 50 is provided to the rear surface of the case 51. As shown in Figure 2 , the lock mechanism 50 has a lock cylinder 53 and an operation member 55 on the outside of the case 51. In addition, as shown in Figure 3 , the lock mechanism 50 has a flat cam support member 60 and a cam mechanism 70 mounted to the cam support member 60 on the inside of the case 51.

[0061] By pressing the operation member 55, the lever 59 is inclined to actuate the cam mechanism 70, and the fixation between the rear portion 40a of the lid member 40 and the rear portion of the case 51 is released. Thus, the lid member 40 can be opened and closed.

[0062] The key 54 can be inserted into the lock cylinder 53 and rotated. In the case where the key 54 is turned to a locked position, a rotation lock plate 57 installed to the lock cylinder 53 is turned, and the lock mechanism 50 is locked so that the fixing between the cover member 40 and the housing 51 cannot be released even if the pressing of the operation member 55 is performed. When the lock mechanism 50 is locked, the rotation lock plate 57 is in the position shown by the solid line in FIG. 6, and when it is not locked, the rotation lock plate 57 is in the position shown by the dotted line in FIG. 6. Figure 3 Figure 3

[0063] In the present embodiment, the operation member 55 is a button which can be pressed, but the application of the present application is not limited to the button-type operation member 55. For example, it can be a handle-type operation member which releases the fixing between the rear portion 40a of the cover member 40 and the rear portion of the housing 51 by pulling or a cable-based operation.

[0064] Figure 4 FIG. 7 is a perspective view of the lock mechanism 50, Figure 5 FIG. 8 is a perspective view of the lock mechanism 50 viewed from the rear.

[0065] As shown in FIG. 9, the cover member 40 is provided with a pin fixing member 41 and a lock pin 43. Figure 4

[0066] The upper portion of the pin fixing member 41 is fixed to the cover member 40. The pin fixing member 41 has two protruding portions 41a in the lower portion and is formed so as to sandwich the cam support member 60 and the first cam 80 between the two protruding portions 41a arranged in the front-rear direction. In addition, the lock pin 43 is fixed between the two protruding portions 41a.

[0067] As shown in FIG. 10, in the present embodiment, the lock cylinder 53 is disposed between the operation member 55 and the cam mechanism 70, and the lock mechanism 50 is arranged compactly. Figure 5

[0068] The cam support member 60 is installed to the rear portion of the housing 51 by a fixing member 69. The cam mechanism 70 is provided with the first cam 80 and the second cam 90. The first cam 80 and the second cam 90 are rotatably installed to the cam support member 60 by means of a first cam support shaft 81 and a second cam support shaft 91, respectively.

[0069] The rod 59 connected to the operation member 55 is arranged at a position which lifts a rod receiving portion 92 provided to the second cam 90 by tilting about the rod support shaft 52. In addition, the rod 59 is structured so as to return to a normal position by being supported by an elastic member (not shown) such as a spring.

[0070] As shown in FIG. 11 and FIG. 12, Figure 4 Figure 5 ​​​​​As shown, a tension spring 71 is provided in tension between the first spring connecting portion 89 of the first cam 80 and the second spring connecting portion 99 of the second cam 90.

[0071] The first cam 80 is always urged in the first cam support shaft 81 center direction by the tension of the tension spring 71. Figure 5 The second cam 90 is always urged in the second cam support shaft 91 center direction by the tension of the tension spring 71. Figure 5

[0072] Figure 6 is a cross-sectional view of a cross section including the first cam 80 and the second cam 90. Also, in Figure 6 , the lock mechanism 50 is in a locked state, and the tension spring 71 is shown in broken lines for ease of explanation.

[0073] The first cam 80 has a first recess 83 into which the lock pin 43 is inserted, and a first hooking portion 85 that abuts against the second cam 90. Also, the first cam 80 has a first engagement protrusion (part of the cam member) 87 that is inserted into the first guide portion (guide portion) 65 of the cam support member 60, and a first curved portion 82 that abuts against the lock pin 43 when the cover member 40 is closed.

[0074] The first guide portion 65 is a hole portion formed in a circular arc shape around the first cam support shaft 81, and the first cam 80 is inhibited from wobbling and also limited in the rotation angle by sliding the first engagement protrusion 87 inside the first guide portion 65.

[0075] The second cam 90 has a second protrusion portion 93 that abuts against the rotation lock plate 57, and a second hooking portion 95 that abuts against the first hooking portion 85 of the first cam 80.

[0076] Also, the second cam 90 has a second engagement protrusion (part of the cam member) 97 that is inserted into the second guide portion (guide portion) 67 of the cam support member 60.

[0077] The second guide portion 67 is a hole portion formed in a circular arc shape around the second cam support shaft 91, and the second cam 90 is inhibited from wobbling and also limited in the rotation angle by sliding the second engagement protrusion 97 inside the second guide portion 67.

[0078] The cam support member 60 has a plate recess 61 into which the rotation lock plate 57 is inserted, an abutting portion 62 provided to the plate recess 61, and a pin recess 63 into which the lock pin 43 is inserted when the cover member 40 has been closed.

[0079] ​In the present embodiment, the rotation lock plate 57 is inserted into the plate recess 61, and when the rotation lock plate 57 is positioned at a position along the abutting portion 62, the rotation lock plate 57 interferes with the second protrusion portion 93, thereby restricting the rotation of the second cam 90.

[0080] Further, in the state where the rotation of the second cam 90 is restricted, in the case where the second cam 90 is rotated in the counterclockwise direction due to an excessive force, the rotation lock plate 57 abuts against the abutting portion 62 of the plate recess 61, and the rotation in the counterclockwise direction is restricted by the abutting portion 62.

[0081] Further, the abutting portion 62 need not be provided to the plate recess 61, but as long as the abutting portion 62 is provided to a face or an edge opposite to the direction of rotation of the second cam 90 based on the lever 59 in the cam support member 60 within the range of rotation of the second cam 90. For example, even if the abutting portion 62 is provided to a protrusion formed in the cam support member 60, the rotation of the second cam 90 due to an excessive force can be restricted by the abutting portion 62.

[0082] Hereinafter, the operation of the locking mechanism of the storage case 30 having the above-described structure will be described with reference to the drawings. Figures 6 to 8

[0083] (State where the cover member 40 is closed)

[0084] In this state, as shown in FIG. 6, the rotation lock plate 57 is withdrawn from the plate recess 61 formed in the cam support member 60. Figure 7 The first cam 80 is urged in the counterclockwise direction in the drawing by the elastic force of the tension spring 71, and the first engagement protrusion 87 abuts against the end wall 65a of the first guide portion 65. Further, the second cam 90 is urged in the clockwise direction in the drawing by the elastic force of the tension spring 71, and the second engagement protrusion 97 abuts against the end wall 67a of the second guide portion 67.

[0085] (Action of closing the cover member 40)

[0086] When the cover member 40 is closed, first, the locking pin 43 provided to the cover member 40 enters the pin recess 63 formed in the cam support member 60, and then comes into contact with the first curved portion 82 of the first cam 80 and pushes the first curved portion 82.

[0087] When the cover member 40 is further closed, the locking pin 43 causes the first cam 80 to start rotating in the clockwise direction in the drawing against the elastic force of the tension spring 71, thereby entering the first recess 83 of the first cam 80.

[0088]

[0089] ​​When the first cam 80 rotates, the first hook portion 85 of the first cam 80 engages with the second hook portion 95 of the second cam 90, overcoming the elastic force of the tension spring 71, causing the second cam 90 to rotate counterclockwise. When the first hook portion 85 passes the second hook portion 95, it returns due to the elastic force of the tension spring 71, and the second cam 90 rotates clockwise, with the first hook portion 85 and the second hook portion 95... Figure 6 It engages as shown.

[0090] When the cover component 40 is fully closed, the locking pin 43 is constrained in a generally rectangular area S (see reference 83) surrounded by the first recess 83 and the pin recess 63. Figure 6 )Inside.

[0091] (Action to open cover component 40)

[0092] When the cover component 40 is closed, such as Figure 6 As shown, the locking pin 43 is constrained in region S. Here, as described above after the action of immediately closing the cover component 40, when the locking mechanism 50 is not locked, Figure 6 The rotating locking plate 57 retracts and disengages from the plate recess 61.

[0093] In this state, when the operating component 55 is pressed, the lever 59 tilts about the lever support shaft 52, lifting the lever support portion 92. When the lever support portion 92 is lifted, the second cam 90... Figure 8 As shown, the second hook 95 disengages from the first hook 85 of the first cam 80 when rotated counterclockwise. This disengagement releases the restriction on the rotation of the first cam 80, and the first cam 80 begins to rotate counterclockwise via the tension spring 71.

[0094] By rotating the first cam 80, the locking pin 43 disengages from the first recess 83 and the pin recess 63, and the cover component 40 is opened.

[0095] (The action of locking mechanism 50)

[0096] On the other hand, after the cover component 40 is fully closed, such as Figure 4 As shown, key 54 can be inserted into lock cylinder 53, causing key 54 to turn to the locked position. Thus, as... Figure 6 As shown, the rotating locking plate 57 is inserted into the plate recess 61 and rotated to a position along the abutment portion 62, locking mechanism 50 is locked.

[0097] Further, the rotation lock plate 57 can not be provided to the lock cylinder 53. For example, the rotation lock plate 57 can be rotated by an electronically controlled device. In addition, even if not a rotational motion, the rotation lock plate 57 can lock the lock mechanism 50 at a position along the abutting portion 62 and can be moved to a position not to lock the lock mechanism 50.

[0098] (Action at the time of locking of the lock mechanism 50)

[0099] When the lock mechanism 50 is in the locked state, in the case where the operation member 55 is pressed down, the rod 59 of the operation member 55 lifts up the rod receiving portion 92. When the rod receiving portion 92 is lifted up, the second cam 90 is rotated in the counterclockwise direction in the figure. However, in this case, the second protruding portion 93 of the second cam 90 is in contact with the rotation lock plate 57, and the rotation of the second cam 90 is restricted.

[0100] When the rotation of the second cam 90 is restricted, the second hooking portion 95 continuously abuts against the first hooking portion 85 of the first cam 80, and thus, even if the operation member 55 is pressed down, the state where the rotation of the first cam 80 is restricted can be maintained. Thus, the lock pin 43 maintains the state of being surrounded by the first recessed portion 83 and the pin recessed portion 63, and thus, the cover member 40 is not opened.

[0101] At this time, the second protruding portion 93 is in contact with the rotation lock plate 57, and the rotation of the second cam 90 is restricted, and thus, the movable range of the rod receiving portion 92 is also restricted. Thus, at the time of locking of the lock mechanism 50, the range in which the operation member 55 can be pressed down is also restricted.

[0102] In this way, in the case where the lock mechanism 50 is locked, the pressing down of the operation member 55 itself is restricted, and thus, the operator who has pressed down the operation member 55 can determine whether the lock mechanism 50 is locked or not based on the feeling at the time of pressing down the operation member 55.

[0103] In addition, at the time of locking of the lock mechanism 50, a case where the operation member 55 is pressed down with a large load for some reason is also considered.

[0104] In this case, the second protruding portion 93 is pressed against the rotation lock plate 57 with a large force. Thereby, the rotation lock plate 57 can be flexed or deformed in the rotation direction of the second cam 90.

[0105] In the present embodiment, the rotation lock plate 57 flexed or deformed by an amount or more is pressed against the abutting portion 62 of the plate recessed portion 61. Thereby, the rotation lock plate 57 is reinforced by the abutting portion 62, and it is possible to suppress the rotation lock plate 57 from being separated from the second protruding portion 93 of the second cam 90 due to the flexure or the deformation.

[0106] Therefore, even when the operation member 55 is pressed with a large load, the rotation of the second protrusion portion 93 is easily continuously restricted by the rotation lock plate 57, and the locking of the locking mechanism 50 is easily maintained.

[0107] As explained above, according to the embodiment to which the present application is applied, the locking mechanism 50 of the storage box 30 can release the fixation of the locking pin 43 of the cover member 40 by the rotation action of the first cam 80 and the second cam 90. The locking mechanism 50 of the storage box 30 is provided with: a cam support member 60 that supports the first cam 80 and the second cam 90; and a rotation lock plate 57 that restricts the rotation of the first cam 80 and the second cam 90, the rotation lock plate 57 restricting the rotation of the first cam 80 and the second cam 90 when being positioned along an abutting portion 62 provided in the cam support member 60.

[0108] According to this structure, the rotation lock plate 57 that restricts the rotation of the first cam 80 and the second cam 90 is reinforced by the abutting portion 62 of the cam support member 60. Therefore, when the rotation lock plate 57 is positioned along the abutting portion 62, even if a strong force is applied to the rotation lock plate 57, the locking of the locking mechanism 50 is difficult to be released.

[0109] In addition, the second cam 90 is rotated by the action of an operation member 55 that is driven by the operation of a user, and the rotation is restricted by the rotation lock plate 57.

[0110] According to this structure, the rotation lock plate 57 restricts the rotation of the second cam 90 that is linked to the operation member 55, and thus the movable range of the operation member 55 itself is restricted. Therefore, the operator can confirm whether the locking is completed or not by the sense of touch when operating the operation member 55.

[0111] In addition, the cam support member 60 is provided with a first guide portion 65 and a second guide portion 67 in which the first engagement protrusion 87 and the second engagement protrusion 97 of the first cam 80 and the second cam 90 slide.

[0112] According to this structure, the first guide portion 65 and the second guide portion 67 guide the rotation of the first cam 80 and the second cam 90, and thus the shaking of the first cam 80 and the second cam 90 can be suppressed. In addition, by restricting the rotation range of the first cam 80 and the second cam 90, the first cam 80 and the second cam 90 can be prevented from rotating to an unexpected angle.

[0113] In addition, the rotation lock plate 57 is operated in rotation by a lock cylinder 53 that is disposed between the operation member 55 and a cam mechanism 70 having the first cam 80 and the second cam 90.

[0114] According to this structure, the locking mechanism 50 provided to the storage box 30 can be configured compactly.

[0115] [Structure supported by the above-described embodiment]

[0118] According to this structure, the rotational lock plate that restricts rotation of the cam member is reinforced by being provided to the abutting portion of the cam support member.

[0120] According to this structure, the rotational lock plate restricts rotation of the second cam that is linked to the operation member, and thus, a movable range of the operation member is also restricted. Therefore, a user can confirm whether or not locking is completed by a sense of touch when the operation member is operated.

[0121] (Structure 3) The locking mechanism of a storage box according to Structure 1 or 2, characterized in that a guide portion is provided to the cam support member, and a portion of the cam member slides at the guide portion.
