Description
Technical Field
The invention relates to a part of an electric motorcycle, in particular to a battery positioning device of an electric motorcycle.
Background
Referring to fig. 1, most of the batteries 10 of the electric vehicles on the market are designed as exchangeable batteries, and a pressing structure 111 corresponding to the arrangement position of the battery 10 is designed on the inner side of a seat 11, so that the pressing structure 111 can be used to press the battery 10 in the storage box downward while the seat 11 is closed, thereby fixing the battery 10 and preventing the battery from jumping up and down to cause power failure. However, when the seat 11 and the pressed structure 111 have negative tolerance in the manufacturing stage, a gap is formed between the pressed structure 111 and the battery 10, so that the seat 11 may not be completely attached to the battery 10 after being closed, thereby greatly reducing the fixing effect of the battery 10. In addition, in order to avoid the situation that the seat cushion 11 cannot be closed due to positive tolerance, the pressing structure 111 is usually made of a slightly elastic material such as rubber, but this is considered to make the battery 10 easily bounce in a direction toward the pressing structure 111 due to vehicle body vibration during driving, and instantly get away from the pressing effect generated by the pressing structure 111, thereby causing a dangerous situation of power failure during driving, and instead losing the arrangement purpose of the pressing structure 111, which is necessary to be improved.

Detailed Description
Before the present invention is described in detail, it should be noted that like elements are represented by like reference numerals throughout the following description.
Referring to fig. 2, a first embodiment of the battery positioning device of the electric vehicle of the present invention includes a vehicle body 91 defining a receiving space 910 for two batteries 8 (only one of which is visible in the angle shown in fig. 2) disposed in parallel, and a seat 92 pivotally connected to the vehicle body 91 and openably covering the vehicle body 91. The first embodiment comprises an actuating unit 2 adapted to be mounted on a side of the vehicle body 91 facing the joint of the seat 92, and a brake unit 3 detachably contacting the actuating unit 2. It should be noted that, although the first embodiment is suitable for the vehicle type where two batteries 8 can be installed, the actual implementation may also be suitable for the positioning requirement of a single battery 8, and the invention is not limited thereto.
Referring to fig. 2 and fig. 3, the actuating unit 2 includes a fixed member 21 adapted to be fixed to the vehicle body 91, a pivot member 22 pivotally disposed on the fixed member 21, a pressing member 23 connected to the pivot member 22 and capable of rotating with the pivot member 22 relative to the fixed member 21, and an elastic member 24 sleeved on the pivot member 22. The pressing member 23 has an extending portion 231 connected to the pivot member 22 and extending in a direction away from the pivot member 22, a bending portion 232 bending and extending from the extending portion 231 in a direction toward the batteries 8, and a pad portion 233 detachably disposed below the bending portion 232 and adapted to press the batteries 8. The extending portion 231 and the bending portion 232 are made of metal material, so as to ensure sufficient rigidity of the pressing member 23, and the pad 233 is made of elastic material, preferably rubber material, so as to provide allowance for tolerance and generate auxiliary pressing effect by self elastic restoring force.
Referring to fig. 4 and 5, a projection range of the longitudinal direction of the batteries 8 is defined, namely, a range located right above the batteries 8, and the pressing member 23 is movable relative to the batteries 8 between a fixed position located in the projection range and pressed above the batteries 8 at the same time, and a disengaged position located outside the projection range. It should be noted that, in the first embodiment, in order to further optimize the convenience of use, the elastic member 24 is specifically a torsion spring for accumulating an elastic restoring force that enables the pressing member 23 to automatically return to the disengaged position without being subjected to an external force when the pressing member 23 moves to the fixed position, so that the pressing member 23 is maintained in the disengaged position without being subjected to an external force.
The brake unit 3 is adapted to be mounted on a side of the seat cushion 92 facing the vehicle body 91, and includes a pushing piece 31 adapted to be connected to the seat cushion 92 and extend toward the vehicle body 91. The pushing-abutting piece 31 is used for pushing the pressing piece 23 from the side of the pressing piece 23 far away from the batteries 8 when the seat cushion 92 is covered on the vehicle body 91, thereby driving the pressing piece 23 to move to the fixed position. Therefore, as long as the first embodiment completes the action of closing the seat 92 that is inevitably performed before the electric vehicle travels, the pushing-abutting piece 31 moves toward the extending portion 231 of the pressing member 23 of the actuating unit 2 as shown in fig. 5 in the process of moving toward the vehicle body 91 along with the seat 92, and continuously pushes the extending portion 231 until the seat 92 is completely closed, and at the same time, the moving stroke of the pushing-abutting piece 31 just enables the bending portion 232 and the pad portion 233 of the pressing member 23 to be pressed on the batteries 8 together, that is, the pressing member 23 moves to the fixed position, so as to achieve the purpose of reliably positioning the batteries 8 when the electric vehicle travels, and effectively avoid the dangerous situation of power failure when the electric vehicle travels on a bumpy road.
In addition, when the user may open the seat 92 to replace the battery 8, the urging piece is also disengaged from the pressing piece 23 of the actuating unit 2 along with the pivotal opening stroke of the seat 92 away from the vehicle body 91. At this time, the elastic restoring force accumulated by the elastic member 24 automatically restores the pressing member 23 to the disengaged position not restricting the batteries 8, so that the user does not need to additionally perform the operation of disengaging the pressing member 23 from the batteries 8, and the pressing member 23 automatically disengages to allow the batteries 8 to be drawn out for replacement, thereby surely optimizing the use efficiency and convenience.
Referring to fig. 6, a second embodiment of the battery positioning device of the electric vehicle according to the present invention is different from the first embodiment in that: the fixing member 21 of the actuating unit 2 has a fixing portion 211 for the pivot member 22 to pass through, and a locking portion 212 extending from the fixing portion 211 and spaced apart from the pressing member 23. The braking unit 3 includes a bolt 32 passing through the locking portion 212 of the pressing member 23 and the fixing member 21 and used for positioning the pressing member 23 at the fixed position. That is, unlike the free swing of the pressing member 23 of the first embodiment, the pressing member 23 of the second embodiment is continuously maintained at the fixed position by the locking of the bolt 32, which is mainly for the rechargeable type and less in need of replacing the types of the batteries 8. Of course, the second embodiment can also be configured for a vehicle type of power change, so that the user can choose whether to lock the bolt 32, so that the pressing member 23 is kept at the fixed position to continuously position the batteries 8.
In summary, the battery positioning device of the electric vehicle of the present invention can use the braking unit 3 to actuate the pressing member 23 of the actuating unit 2, so that the pressing member 23 moves to the fixed position, and the battery 8 is positioned by using its relatively strong rigidity, thereby avoiding the power failure caused by the bouncing generated when the vehicle runs on a bumpy road. Therefore, the object of the present invention can be achieved.
The above description is only an example of the present invention, and the scope of the present invention should not be limited by the above description, and all the simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention are still included in the scope covered by the present invention.
