Embodiment
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
Embodiment：A kind of flexible connection safeguard structure maintainable with electricly connecting position for motor of the present invention, such as
Accompanying drawing 1, accompanying drawing 2, shown in accompanying drawing 3, it includes：Rubber seal 10, it is the cylinder of both ends open, is placed on the outside of three-phase wire harness 9,
Lower end oral area is sealedly attached to motor assembly 12；Upper end oral area, which extends radially outwards, circularizes plate, annular slab bottom surface fasten have on
Arm-tie 8, upper arm-tie 8 are ring bodies；Trip bolt 3 in casing 7 is formed with upper arm-tie 8 to be fastenedly connected, and is pressed against annular slab
In the bottom of casing 7 to form flat seal；Upper lid 6, located at the top of casing 7, top has the trip bolt 3 in operation casing 7
It is relative with the upper port of rubber seal 10 with the opening of the fixing end of three-phase wire harness 9, the opening；And envelope hides opening for the upper opening of lid 6
Lid 1.
The opening portion that envelope hides upper lid 6 has ring-shaped platform, and ring-shaped platform bottom sets support rubber cushion 4 and support frame 5, ring
Shape platform inner peripheral is folded upward at cyclic side, and ring side root sets lid sealing ring 2；The outer rim of vent cover 1 is resisted against on ring-shaped platform
Portion, it is made up of and is fastenedly connected with support frame 5 trip bolt 3, and friction top sealing ring 2 forms vent cover 1 and ring-shaped platform
It is tightly connected, while compresses the sealing that support rubber cushion 4 forms screw hole portion.
The inside stage casing of rubber seal 10 sets diaphragm plate, and three-phase wire harness 9 passes through in the middle part of diaphragm plate.It is set to be not easy partially
Put, do not contact directly, play a protective role with the side wall of rubber seal 10.
The hole portion of motor assembly 12 is stretched into the lower end of rubber seal 10, and inserting end periphery has two annular bars, wherein
The annular bar of downside is abutted on the lateral wall of the hole portion of motor assembly 12；The motor assembly 12 is provided with lower platen 11, lower platen
11 section is hook, hooks end and stretches between two annular bars of rubber seal 10；Lower platen 11 is locked by trip bolt 3
Due to motor assembly 12, and the annular bar of the downside of rubber seal 10 is pressed on the lateral wall of the hole portion of motor assembly 12 and sealed
Connection.
By such scheme, maintenance position sealed protective structure mode is：Spiral shell is passed through by maintenance vent cover 1 (stretching sheet material)
The upper lid 6 (stretching sheet material) of the connection of nail 3 and rubber blanket 4 and support frame 5, the sealing protection between vent cover 1 and upper lid 6 is by sealing ring 2
Realize, the sealing between upper lid 6 and trip bolt 3 is realized by support rubber cushion 4, as shown in Figure 2.
Protective structure approach between control system and motor is：Casing 7 connects upper arm-tie 8 by trip bolt 3, middle
Rubber seal 10 is pressed from both sides, realizes that control system and the sealing protection of the i.e. rubber seal 10 of flexible connection structure are connected.Lower platen 11
By trip bolt 3, centre folder rubber seal 10, it is connected with motor assembly 12, finally realizes between control system and motor
Sealing IP67 degree of protection, as shown in Figure 3.
When safeguarding, after vent cover 1 is opened, the fixing screws of three-phase wire harness 9 are released, release the trip bolt 3 of connection casing,
The fractionation of three-phase line position between i.e. achievable two systems.
By above-mentioned two organization plans, the flexible connection and sealing protection for realizing motor and control system electrical joint are imitated
Fruit, while the simple fractionation of two systems is realized, finally realizing the maintenance cost of electrical drive power assembly reduces, and optimizes electrical connection section
Bit architecture is rigidly connected, the vibrations transmission of caused motor, decelerator, improves NVH performances.
