Definitions
- the present invention relates to an electric pump including a pump unit, a motor unit for driving the pump unit, and a driver chamber including a driver for controlling the motor unit.
- the substrate of the driver of the electric pump is fixed by screw members to the tips of a plurality of mounting projections integrally formed of resin with the motor housing. For this reason, the vibration generated in the motor unit and the pump unit is easily transmitted to the substrate, the connector terminals and terminals electrically connecting the motor unit and the driver are damaged, and the various electronic elements provided on the substrate are adversely affected. There was a risk of giving Further, in the electric pump of Patent Document 1, when a gap is generated between the heat dissipation member and the cover, the heat transfer from the driver to the cover is not smoothly performed, and the heat dissipation may be greatly reduced.
- the cover is fixed to the motor housing with a screw member, and a sealing member is provided to ensure the sealing performance at this fixed location. This has led to an increase in the number of parts.
- the present invention has been made in view of the above problems, and it is an object of the present invention to provide an electric pump which is less likely to cause a driver failure due to vibration and can reduce the number of parts.
- a first characteristic configuration of an electric pump according to the present invention includes a pump unit, a motor unit for driving the pump unit, and a driver chamber including a driver for controlling the motor unit, and at least one of the driver chambers

Therefore, damage to connector terminals and terminals can be prevented, and adverse effects on various electronic elements on the substrate can be suppressed.
- a urethane resin can be used as the potting material, but this type of resin is easily thermally expanded. Therefore, when the entire driver chamber is filled with the potting material, there is no room for the potting material at the time of thermal expansion, and the load on the substrate is increased. Therefore, if the non-filling space where the potting material is not filled is left in the driver chamber along the surface direction of the substrate as in the present configuration, the potting material can escape to the non-filling space during thermal expansion. Therefore, the load applied to the substrate at the time of expansion of the potting material can be reduced. Further, the heat generated by the driver is absorbed by the potting material and dissipated from the wall of the driver chamber through the potting material, so that the temperature rise of the substrate can be reduced.

- the motor housing and the driver case are integrally formed by welding, the screw member for attaching the driver case to the motor housing and the seal member disposed between the motor housing and the driver case become unnecessary. . As a result, the number of parts can be further reduced.
- the space on the one side is a space on the opposite side to the motor unit with respect to the substrate, and the space on the other side is a space on the side of the motor unit with respect to the substrate It is at a certain point.
- the potting material is filled in the space of the driver chamber in the space on the opposite side to the motor portion of the substrate of the driver, the heat of the potting material is released to the outside of the electric pump It will be easier. Therefore, the load acting on the substrate of the driver can be reduced by the thermal deformation of the potting material.

Therefore, the vibration generated in the motor unit 3 and the pump unit 2 is attenuated by the potting material 52, and the vibration transmitted to the substrate 44 is reduced. Therefore, damage to the connector terminals 47 and the terminals 48 can be prevented, and an adverse effect due to vibration on various electronic elements on the substrate 44 can be suppressed.
