[Problems to be solved by the invention]

In a general straddle type vehicle, the unlocking cable for unlocking is embedded in the cable groove of the base side wall of the seat lock. However, the cable slot is open to the rear, so the unlocked cable may fall out from the cable slot to the rear. Therefore, a person who knows the arrangement position of the seat lock can use a tool to pull out the unlocking cable (unlocking operation member) or disable it through the gap or hole between the vehicle bodies. In particular, there is a risk that the angle from which the seat lock can be directly or indirectly approached, for example, from behind or below the vehicle, insert a slender tool into the interior of the vehicle, along with the unlocking cable. The cable slot pushes the unlocking cable in the direction of the rear, and theft or mischief of the unlocking seat lock will occur.

In order to solve the above problems of theft or mischief, the straddle-type vehicle of Patent Document 1 is provided with a shielding shell covering the seat lock from the rear, thereby preventing the unlocking cable from coming out of the cable slot, so it is considered advantageous To prevent theft or mischief of the seat lock.

However, in the vehicle of the above-mentioned Patent Document 1, it is necessary to take time to form the shielding case covering the seat lock from the rear as an independent entity in order to prevent theft or mischief of the seat lock. For example, in order to cover the entire seat lock, the shielding shell needs to be formed with a recess that can accommodate the seat lock, and in order to prevent the shielding shell from occupying a large space inside the vehicle, it is necessary to combine the seat lock The outer shape forms the surface of the shielding shell, and furthermore, mounting holes, mounting seats or bolts and nuts for fastening the shielding shell are also required.

Therefore, the inventor of the present invention has focused on the arrangement of the vehicle electronic control device and the battery at the rear of the straddle-type vehicle of the above-mentioned Patent Document 2 in order to eliminate the disadvantage of requiring a lot of time to shield the casing. In the straddle-type vehicle of Patent Document 2, the electronic control device for the vehicle and the battery are provided at the rear of the vehicle, so it is possible to protect the seat lock device which is also provided at the rear of the vehicle and is further forward. Components to function have been studied.

As a result, the following scheme was conceived. In view of the above-mentioned Patent Document 1, it is necessary to remove the shielding case which requires a lot of effort, and as in Patent Document 2, behind the seat lock device, adjacent to the vehicle electronic control device, a The battery for supplying electric current to the electronic control device for a vehicle shortens the wires connecting the two, and is provided as a protection element against theft or the like.

However, the inventor of the present invention has further studied and found that the electronic control device for a vehicle of Patent Document 2 and the battery are housed in one rear storage room, and are arranged in such a manner that the positions of the vehicle in the vertical direction in the rear storage room are substantially the same. When the rear storage compartment of the above-mentioned Patent Document 2 is arranged below the seat lock of the above-mentioned Patent Document 1, it is impossible to protect against improper access from behind the vehicle, on the other hand, when it is arranged behind It is impossible to protect against improper access from below the vehicle, so it is impossible to protect against improper access from behind and below the vehicle at the same time. Therefore, even if the arrangement of the electronic control device for a vehicle and the battery of Patent Document 2 is applied to Patent Document 1, theft or mischief of the seat lock of the vehicle cannot be reliably prevented.

The present invention has been completed in view of the above circumstances, and its object is to provide a straddle-type vehicle that removes a shielding case that takes a lot of time and also prevents theft or mischief of the seat lock. [Technical means to solve the problem]

As a result of our vigorous research, the inventor believes that the SGCU-type vehicle electronic control device, which has both a drive circuit for driving an electric motor and a control circuit for controlling in-vehicle electronic parts, is larger than the previous vehicle electronic control device. Therefore, it has advantages in avoiding theft or mischief. It was also found that the use of the advantages of the SGCU-type vehicle electronic control device and the arrangement relationship between the SGCU-type vehicle electronic control device and the battery unit can prevent theft or mischief of the seat lock. That is, the inventor has thought of: as long as the relative positional relationship between the SGCU-type vehicle electronic control device and the battery unit is taken into consideration, the SGCU-type vehicle electronic control device and the battery unit fully cover the seat lock, It can prevent theft or mischief caused by improper unlocking of the seat locking device.

In addition, in the following description of the invention of this case, as long as it is not specifically explained, the so-called "vehicle electronic control device" refers to the SGCU type that has both a drive circuit that drives an electric motor and a control circuit that controls on-board electronic parts. Electronic control device for vehicles.

Specifically, in order to solve the above-mentioned problems, a battery unit arranged behind the front-rear direction of the vehicle in the storage box and an SGCU-type vehicle electronic control device including a drive circuit and a control circuit can be used. The battery unit is arranged under the seat locking device and is overlapped with the seat locking device in a plan view of the vehicle. This prevents access from below the vehicle. In addition, the electronic control device for the vehicle is arranged behind the battery unit, and the upper edge of the electronic control device for the vehicle protrudes above the upper wall portion of the battery unit and is positioned above at least a part of the locking device of the seat portion State configuration. This prevents the vehicle from approaching.

As a result, even if the shielding case as an independent body is not provided as in Patent Document 1, it is difficult to access the seat locking device, and it can be protected by the vehicle electronic control device and the battery unit. Therefore, even those who know the position of the seat lock can not pull out or invalidate the unlocking operation member (unlocking cable) from behind or below the vehicle, thereby preventing theft or mischief, etc. Therefore, it is possible to not only save unnecessary shielding shells, but also prevent theft or mischief.

However, the inventor found that when the upper edge of the electronic control device for a vehicle is arranged in a state where at least a part of the locking device of the seat portion is positioned above, the following new problem arises.

The electronic control device for a vehicle configured as described above has both a control circuit and a drive circuit. As described above, the control circuit controls the operation of the drive circuit, while the drive circuit drives the driven device, and is generally composed of components that generate more heat than the control circuit equipped with heat generating elements such as FETs. Therefore, regarding the configuration of the SGCU type vehicle electronic control device, it is necessary to fully consider the heat dissipation compared to the previous vehicle electronic control device without a driving circuit.

However, in a general straddle-type vehicle, in order to prevent the peripheral parts of the seat locking device from being exposed to the outside when the seat is opened, resulting in deterioration of aesthetics, a partition plate is provided above the seat locking device.

When the upper edge of the vehicle electronic control device is disposed above at least a part of the seat locking device, the heat dissipation space above the vehicle electronic control device is blocked by the partition plate and becomes smaller, so there is a The heat dissipation of the electronic control device for vehicles may be affected.

In other words, in the case of using an SGCU type electronic control device for a vehicle to prevent theft or mischief of a seat lock, how to improve the anti-theft property and eliminate the SGCU type electronic control device for a vehicle as much as possible The effect of heat dissipation becomes an important issue. Therefore, the present inventors have made intensive studies to solve the derivative problem of reducing the heat dissipation caused by the reduction of the heat dissipation space above the SGCU type electronic control device for vehicles.

Generally speaking, when the partition plate is provided, an opening is provided in the partition plate in order to allow the seat fastener provided at the rear of the seat to extend downward. Therefore, the inventors thought of using the opening of the partition plate to solve the problem of lowering the heat dissipation of the electronic control device for vehicles derived from the improvement of anti-theft properties.

Specifically, the straddle-type vehicle further includes a partition plate, which is disposed below the seat portion and above the vehicle electronic control device in the vertical direction of the vehicle, and a seat buckle is formed on the partition plate The opening through which the piece passes. In addition, the opening is located above the upper edge of the electronic control device for the vehicle and above the seat locking device, and overlaps the seat locking device in a plan view of the vehicle. With this, when the upper edge of the vehicle electronic control device is disposed above the upper wall portion of the battery unit, the vehicle electronic control device is close to the opening, so the heat energy of the vehicle electronic control device passes through The opening is released into the space above the partition plate.

Thereby, when the seat is closed, the heat energy of the vehicle electronic control device is released to the space above the partition plate and below the seat through the opening. Specifically, in order to prevent theft or mischief of the seat locking device, which leads to the reduction of the heat dissipation space above the electronic control device for the vehicle, it can be used by forming above the partition plate and below the seat Space to solve the problem by expanding the heat dissipation space. That is, when the upper edge of the vehicle electronic control device is disposed above at least a part of the seat locking device, even if the heat dissipation space above the vehicle electronic control device becomes smaller, it can be used to form The space above the partition plate and below the seat portion complements the heat dissipation space above the vehicle electronic control device, thereby solving the problem of lowering the heat dissipation of the vehicle electronic control device. As a result, the anti-theft performance can be improved, and even if the heat dissipation space above the vehicle electronic control device is limited, the vehicle electronic control device can efficiently dissipate heat.
