Description

The battery receiving device of battery-driven car

[technical field]

The utility model is about a kind of accommodation apparatus, particularly about a kind of battery receiving device of battery-driven car.

[background technology]

Consult Fig. 1, existing battery-driven car 1 comprises pipe 11, one vehicle body frame 12, that is connected in this pipe 11 and is hubbed at seat cushion 13, on this vehicle body frame 12 and is arranged at positioning seat 14 in this vehicle body frame 12, and a detouchable is arranged at the electric power supply unit 15 of this positioning seat 14.

Consult Fig. 2, this positioning seat 14 has one and is fixedly arranged on pedestal 141, on this body framework 12 and is formed at a location division 142 in this pedestal 141 and a locations 143 that is arranged in this location division 142.And this electric power supply unit 15 has the carrying handle 153 that a battery case 152, that is installed in several batteries 151 (only showing among the figure) is hubbed at these battery case 152 tops, and one is formed at positioning groove 154 on this battery case 152 with this locations 143 with matching.Utilize this positioning groove 154 battery case 152 of this electric power supply unit 15 to be positioned in the location division 142 of this positioning seat 14 with cooperatively interacting of this locations 143.

Consult Fig. 1,2, when existing battery-driven car 1 changes the outfit electric power supply unit 15, be that this seat cushion 13 is started according to direction shown in Fig. 1 arrow, utilize this carrying handle 153 that battery case 152 is mentioned again, and after making the locations 143 of positioning groove 154 these positioning seats 14 of alignment on this battery case 152, this battery case 152 could be inserted in this location division 142 by this opening part.

But, the battery case 152 that is installed in several batteries 151 easily several kilograms do not wait to tens of kilograms, this battery case 152 to be mentioned being difficult for more, also will be after mentioning this battery case 152 arduously, it will be more difficult making the locations 143 of positioning groove 154 these positioning seats 14 of alignment on this battery case 152 again, careless slightlyly will cause this battery case 152 bottom surface of dropping, may cause the damage of this battery case 152, and more may cause the user to suffer this battery case 152 to injure safety by a crashing object and cause anxiety.

And this positioning seat 14 only borrows this locations 143 to cooperatively interact with this positioning groove 154, so that this battery case 152 is positioned in this location division 142, make vibrations or impulsive force that this battery case 152 is produced when battery-driven car 1 is advanced only unilaterally absorb by this locations 143, cause fall sharply the service life of this locations 143, and then this battery case 152 can't stably be positioned in this location division 142.

Certainly be arranged at the mode of the locations 143 in the location division 142 by increase, solve the short shortcoming in service life of single locations 143, but, in case increase the locations 143 in the location division 142, degree of difficulty in the time of certainly will increasing battery case 152 with these positioning seat 14 assemblings is so this kind improvement is not a good plan.

In order to improve above-mentioned shortcoming, relevant dealer develops as M331761 number disclosed technology of novel patent of TaiWan, China, its mainly improvement place be two guide grooves that on positioning seat, are shaped, and on this battery case, be convexly equipped with two guide members relatively, by cooperatively interacting of this two guide groove and this two guide member make this battery case can be smoothly and this positioning seat mutually combine.

But, when this battery case and this positioning seat mutually combine, this positioning seat is the periphery that coats this battery case fully, be easy to generate vacuum adsorption phenomenon, cause the difficulty of taking out battery case, and also make the volume of this positioning seat heighten with the design that this positioning seat coats this battery case periphery fully, cause feed stock cost and manufacture difficulty increase when making positioning seat.Therefore, how simultaneously, have property easy to assembly concurrently, can effectively reduce production costs and manufacture difficulty again, just become the direction that relevant dealer's utmost point desire is improved.

[utility model content]
