Description

Saddle-mounted type vehicle TECHNICAL FIELD

[001] The present invention relates to a saddle-mounted type vehicle. PRECEDENT TECHNIQUE

[002] An electrical component, such as an electronic control unit (ECU), is mounted on a saddle-mounted type vehicle, such as a motorcycle. Since an electrical wire, such as a harness, is usually connected to the electrical component like the ECU, when the harness is pulled, the electrical component can be pulled along with the harness and separated from the saddle-mounted type vehicle, and the electrical component can be stolen by third parties.

[003] To prevent the electrical component from being stolen by third parties, for example, JP2011-046245A describes a motorcycle that includes a rear fender disposed over a rear wheel, a rear frame over the rear fender, an ECU supported by the rear fender, a coupler connected to the ECU in such a way as to be removable to the front, a retention unit provided in the rear fender and supporting the ECU, and a guardrail provided in the rear frame and preventing the ECU from moving forward along with the coupler. In the motorcycle described in JP2011-046245A, even when the harness is pulled, the ECU can be prevented from moving forward along with the coupler by the guardrail, so that the ECU as the electrical component can be prevented from detaching from the motorcycle.

[004] However, in the motorcycle described in JP2011-046245A, as the guardrail and rear fender are separate bodies, the number of components increases. SUMMARY OF THE INVENTION

[005] The present invention provides a ride-on type vehicle H&áççsto8í7IHam^^ 2 / 30 saddle, capable of preventing the detachment of an electrical component even when a harness is pulled, without increasing the number of components.

[006] The embodiment of the present invention relates to providing a saddle-mounted type vehicle including: a covering member configured to cover a vehicle body from underneath; an electrical component supported by the cover member; and a harness removablely connected to the electrical component, wherein a side connector of the electrical component is provided on a first surface of the electrical component facing a direction of insertion and removal of the harness, a side connector of the harness, removablely connected to the side connector of the electrical component, is provided on an end portion of the harness, and the cover member is provided with a restraining portion formed integrally with the cover member by an integral molding with the cover member, in a position where the restraining portion faces the first surface of the electrical component in the direction of insertion and removal, the restraining portion being configured to restrict the movement of the electrical component in the direction of insertion and removal.

[007] According to the present invention, since the restraining portion that restricts the movement of the electrical component in the direction of insertion and removal of the harness is integrally formed with the cover member by integral molding with the cover member, the electrical component can be prevented from being separated from the saddle-mounted vehicle without increasing the number of H&áççsto8í7IEHffiH38^ 3 / 30 components.

[0074] In the present embodiment, motorcycle 1 can access a space enclosed by the main cowl 22 from the front and can access the ECU harness 81 from the front. Consequently, motorcycle 1 can access the ECU harness 81 from the front and insert and remove the ECU harness 81 into and from the electronic control unit 70 without removing the cowl 20.

[0075] The fixed ECU portion 241 of the cover member 24 includes an ECU placement portion 241a that extends substantially flat in the front-to-back and left-to-right directions, and a pair of left and right side wall portions 241b bent upwards from both the left and right ends of the ECU placement portion 241a and extending in the top-to-bottom and front-to-back directions.

[0076] The electronic control unit 70 is fixed to the fixed part ECU 241 of the cover member 24 while it is placed on an upper surface of the ECU 241a placement part.

[0077] The ECU placement portion 241a of the fixed portion ECU 241 extends forward beyond the front surface 70a of the electronic control unit 70. In the present embodiment, the ECU placement portion 241a extends forward beyond the side connector of the harness 811 of the ECU harness 81 in a state where the ECU harness 81 is connected to the electronic control unit 70.

[0078] Similarly to the ECU placement portion 241a, the pair of left and right side wall portions 241b of the portion H&áiçto8í7ffiHffiK^^ 20 / 30 fixed ECU 241 also extends forward beyond the front surface of the electronic control unit 70. In the present embodiment, the pair of left and right side wall portions 241b of the fixed ECU 241 portion extend to a forward end of the ECU 241a placement portion. Consequently, the pair of left and right side wall portions 241b of the fixed ECU 241 portion extends forward beyond the side harness connector 811 of the ECU harness 81 in a state where the ECU harness 81 is connected to the electronic control unit 70.

[0079] A buckle element 242 articulated with the front-to-rear direction as a pivot axis is provided in an upper end portion of the left side wall portion 241b of the fixed ECU portion 241, i.e., the side wall portion 241b on a central side in the direction of the vehicle width. The buckle member 242 has a substantially rectangular annular shape when viewed from above, and both its left and right ends are inclined downwards outwards in the left-to-right direction. A left edge portion of the buckle member 242 functions as a pivot axis extending in the front-to-rear direction. The buckle element 242 is provided in a position that overlaps the upper surface of the electronic control unit 70, as viewed from above.

[0080] A buckle locking portion 241c in which a right edge portion of the buckle member 242 can be locked is formed on an upper end portion of the right side wall portion 241b of the fixed ECU portion 241, that is, the side wall portion 241b on the outside in the direction of the vehicle width. The buckle locking portion 241c is integrally formed with the right side wall portion 241b of the fixed ECU portion 241, that is, formed by an integral molding with the cover member 24. H&áiçto8í7ffiHffiK^^ 21 / 30

[0081] When the right edge portion of buckle member 242 is locked into the buckle locking portion 241c, the upper surface of the electronic control unit 70 is pressed down by the buckle locking portion 241c. The electronic control unit 70 is sandwiched in the top-down direction by buckle member 242 and the ECU placement portion 241a of cover member 24, and is fixed to the fixed ECU portion 241 of cover member 24.

[0082] The pair of left and right side wall portions 241b of the fixed portion of ECU 241 is formed such that the left side wall portion 241b faces the left surface of the electronic control unit 70 and the right side wall portion 241b faces the right surface of the electronic control unit 70 in a state where the electronic control unit 70 is fixed to the fixed portion ECU 241 of the cover member 24. The pair of left and right side wall portions 241b of the fixed portion ECU 241 can be formed such that the left side wall portion 241b abuts the left surface of the electronic control unit 70 and the right side wall portion 241b faces and abuts the right surface of the electronic control unit 70 in the opposite manner, in a state where the electronic control unit 70 is fixed to the fixed portion ECU 241 of the cover member. 24.

[0083] The cover member 24 is provided with a restraining portion 243 in a position where the restraining portion 243 faces the front surface 70a of the electronic control unit 70. The restraining portion 243 prevents the electronic control unit 70 from moving in a front-to-back direction. The restraining portion 243 is integrally formed with the cover member 24.

[0084] Consequently, even when the ECU 81 harness is H&áççsto8í7IEHffiH38^ 22 / 30 pulled in the front-to-rear direction, the electronic control unit 70 is prevented from advancing by the restriction portion 243, so that the electronic control unit 70 can be prevented from being detached from the motorcycle 1. Since the restriction portion 243 is integrally formed with the cover member 24 by integral molding with the cover member 24, the electronic control unit 70 can be prevented from being detached from the motorcycle 1 even when the ECU harness 81 is pulled in the front-to-rear direction without increasing the number of components.

[0085] The restraining portion 243 includes a pair of left and right side wall portions 243a that extend in the top-down and front-to-back directions, and a top wall portion 243b that extends in the left-to-right and front-to-back directions and connects the upper extreme portions of the pair of left and right side wall portions 243a.

[0086] On the ECU side connector 71, a lower region on a left surface facing the left side wall portion 241b of the fixed ECU portion 241 with a predetermined distance between them, an upper region on the left surface facing the left side wall portion 243a of the restriction portion 243 with a predetermined distance between them, a lower region on a right surface facing the right side wall portion 241b of the fixed ECU portion 241 with a predetermined distance between them, an upper region on the right surface facing the right side wall portion 243a of the restriction portion 243 with a predetermined distance between them, an upper surface facing the upper wall portion 243b of the restriction portion 243 with a predetermined distance between them, and a lower surface facing the ECU placement portion 241a of the fixed ECU portion 241 with a predetermined distance between them.Consequently,. H&áççsto8í7IEHffiH38^ 23 / 30 the ECU side connector 71 is surrounded by the restraining portion 243, the left and right side wall portions 241b of the ECU fixed portion 241 and the ECU placement portion 241a as seen from the front in a state where the electronic control unit 70 is fixed to the ECU fixed portion 241 of the cover member 24.

[0087] The pair of left and right side wall portions 243a is arranged so that a distance D1 between them in the left-right direction is less than a left-right dimension L1 of the electronic control unit 70.

[0088] Consequently, when the ECU harness 81 is pulled in the insertion and removal direction (forward in this embodiment), the front surface 70a of the electronic control unit 70 abuts against the pair of left and right side wall portions 243a of the restraining portion 243, so that the electronic control unit 70 is prevented from moving forward. In this way, since the restraining portion 243 can prevent the electronic control unit 70 from moving in the front-to-back direction by the pair of left and right side wall portions 243a, a degree of freedom in the design of the restraining portion 243 in the top-to-bottom direction, such as the arrangement and shape of the upper wall portion 243b, is improved.

[0089] A distance D2 between the upper wall portion 243b of the restraining portion 243 and the upper surface of the ECU side connector 71 is greater than a distance D3 between the upper surface of the ECU placement portion 241a of the cover member 24 and the lower surface of the ECU side connector 71, as seen in the front-to-rear direction.

[0090] Consequently, when the ECU harness 81 is removed from the electronic control unit 70 by pulling the ECU harness 81 in the insertion and removal direction (forward in this embodiment), the ECU harness 81 can be easily removed from the unit. H&áççsto8í7IEHffiH38^ 24 / 30 electronic control 70 even when the ECU harness 81 is pulled obliquely upwards in the direction of insertion and removal.

[0091] At least part of the upper wall portion 243b of the restraining portion 243 extends in a left-to-right direction above the upper surface of the electronic control unit 70, as seen in the front-to-rear direction.

[0092] Consequently, when the ECU harness 81 is removed from the electronic control unit 70 by pulling the ECU harness 81 in the insertion and removal direction (forward in this embodiment), the ECU harness 81 can be easily removed from the electronic control unit 70 even when the ECU harness 81 is pulled obliquely upwards in the insertion and removal direction.

[0093] The upper wall portion 243b of the restraint portion 243 is located in front of buckle element 242, and at least part of it extends in a left-to-right direction above buckle element 242.

[0094] Therefore, while the ECU harness 81 can be accessed from the front, even when the electronic control unit 70 must be accessed from the front, the upper wall portion 243b of the restriction portion 243 prevents access to the buckle element 242, so that it is less likely to access the electronic control unit 70 from the front and remove the electronic control unit 70 from the motorcycle 1. Consequently, an anti-theft effect of the electronic control unit 70 can be improved while the ECU harness 81 can be easily inserted and removed from the electronic control unit 70 by accessing the ECU harness 81 from the front.

[0095] Although one embodiment of the present invention has been described above with reference to the accompanying drawings, it is needless to say that the present invention is not limited to that embodiment.
