Description
Technical field
The utility model relates to the vehicle accessory field, especially relates to a kind of DC motor controller for battery vehicle.
Background technology
Battery vehicle uses powered battery because of it, does not produce waste gas during Vehicle Driving Cycle, has advantages of environment friendly and pollution-freely, is widely used.Existing battery vehicle drives with separately excited DC machine mostly, and therefore existing battery vehicle need to arrange the controller that is arranged on the separately excited DC machine in battery vehicle, is used for controlling the work of separately excited DC machine.
Referring to Fig. 1, existing DC motor controller has a base plate 10, control module 11 is installed on base plate 10, be provided with circuit board (invisible in Fig. 1) in control module 11, circuit board is provided with a plurality of electronic devices, these electronic devices consist of control circuit, are used for separately excited DC machine is controlled.Need to receive outside signal when working due to control circuit, therefore terminal base 12 is set on base plate 10, terminal base 12 is provided with a plurality of binding posts 13, and outside holding wire is electrically connected to control circuit by binding post 13.
In addition, also be provided with magnetic support 14 on base plate 10, also be provided with binding post 15 on magnetic support 14, outside holding wire is electrically connected to magnetic support 14 by binding post 15.
As seen from Figure 1, because the binding post on binding post 13 and magnetic support 14 is not to be arranged near the same end line of base plate 10, and binding post 13 has larger distance with binding post 15, for the attended operation of holding wire makes troubles.In addition, because DC motor controller is placed on the position that battery vehicle exposes usually, work under the environment that control module 11 and magnetic support 14 grades are exposed to the sun and rain through being everlasting, cause the useful life of DC motor controller not long.
Therefore, notification number is that the Chinese utility model patent of CN202491695U discloses the innovation and creation of a kind of " separately excited motor controller " by name, this separately excited machine controller has base plate and is arranged on waterproof cover on base plate, be equipped with on base plate and be provided with control module, one side of control module is provided with a plurality of the first binding posts, also be provided with magnetic support on base plate, magnetic support is connected with the second binding post on being positioned at base plate, and a plurality of the first binding posts and a plurality of the second binding post all are arranged on an end line place near base plate.For the convenience of wiring, this separately excited motor controller is arranged on a plurality of the first binding posts and a plurality of the second binding post, magnetic support outside waterproof cover, so equal outer being exposed at outside waterproof cover of binding post and waterproof cover.
Because DC motor controller need to receive the DC power supply that the outside provides, and after being processed, DC power supply outputs to motor, the direct current make-to-break ratio that the DC power supply that receives provides is more frequent, and often electric current is larger for the DC power supply that receives, and therefore contactor need to be set to reduce the impact to the electronic device in DC motor controller in DC motor controller.
Yet, one or two contactor often only is set in existing DC motor controller, and selects the contactor that can bear larger electric current to satisfy the need of work of DC motor controller.But because the contactor volume that can bear larger electric current is larger, and production cost is higher, causes the volume of DC motor controller larger, and production cost is also higher.And, need will cause the circuit board wiring of control module difficult with the larger contactor of volume, be unfavorable for the manufacturing of DC motor controller.

By such scheme as seen, at the contactor body that arranges on power amplifier board more than four, and be connected in parallel between a plurality of contactor bodies, the electric current that receives there is the effect of shunting, avoid all electric currents contactor body of only flowing through, can select like this and bear electric current than the small contactor body, thereby reduce the volume of the contactor body of selecting and the production cost of the contactor body that reduction is selected.
And because a plurality of contactor bodies are shunted electric current, so contactor assembly still can bear larger electric current, do not affect the performance of DC motor controller.
A preferred scheme is, contactor assembly is arranged on an end line place near power amplifier board, and contactor assembly is arranged in cavity.
This shows, contactor assembly is arranged in cavity, avoid effectively protecting contactor assembly and extending its useful life outside contactor assembly is exposed to.Contactor assembly is arranged on an end line place of power amplifier board, is conducive to the layout to other electronic devices on power amplifier board, also simplify the wiring of power amplifier board.
Further scheme is, a drift angle at the end line place of power amplifier board is provided with breach, in a plurality of contactor bodies one of the most close breach with the spacing of the end line spacing greater than other contactor bodies and end line.
As seen, according to the design of DC motor controller, the drift angle at power amplifier board end line place is arranged breach, in the contactor body one dodges this breach and is arranged on the position away from from end line, is conducive to the design of power amplifier board.
Further scheme is, also be provided with the positive source binding post on power amplifier board, the positive source binding post between two contactor bodies, and the positive source binding post be positioned at power amplifier board on copper bar be electrically connected to, the positive source binding post is electrically connected to a plurality of contactor bodies by copper bar.
This shows, the positive source binding post imports a plurality of contactor bodies by copper bar with electric current, effectively electric current is shunted by copper bar.
