Technical field

The present invention relates to a kind of connection structures suitable for vehicle-mounted power inverter.

Background technique

In using vehicle of the motor as power source, it is installed with for the electric drive motor using battery inverse Become the power inverters such as device, converter.In these power inverters, it is electrically connected about with battery or electronic mechatronics Reliability is connect, mechanical damage in interconnecting piece is led to due to needing to fully consider the external force such as vibration when vehicle driving, because of moisture Or poor flow caused by insulation breakdown etc. caused by foreign conducting matter intrusion.

For such power inverter, especially it is being installed in the indoor feelings of the harsh engine of vibration condition Under condition, in most cases use vibration-proof structure (for example, referring to patent document in the mechanical link connecting with vehicle mechanical 1)。

In addition, from the viewpoint of the connection reliability of electrical connection section, it is single-ended to be connect with external equipments such as battery, motor Harness tighten together mostly via with the integrated bracket of harness itself etc. with power inverter mechanical rigid.It is logical It crosses using such fastening structure, it is ensured that the waterproofness of framework and harness joint portion (for example, referring to patent document 2).

Therefore, in conventional structure, for the electrical connection section for requiring high reliability, delayed using the flexibility of harness With the influence of the external force under harsh vibration condition.In addition, in conventional structure, by with the integrated bracket of harness by frame Body is connect with harness mechanical rigid, ensures that waterproofness.

Summary of the invention

The technical problems to be solved by the invention

However, in the prior art, there are following technical problems.

With the big outputization of power inverter, in order to mitigate the influence because of fever caused by being powered, voltage decline etc., harness Equal electric conductors are necessary to ensure that conducting area.The rigidity of accompanying this, harness itself increases.As a result, soft possessed by harness Soft decline, to be difficult to be suitable for harsh vibration condition.

The present invention makees to solve above-mentioned technical problem, and its object is to obtain a kind of connection knot of power inverter Structure, have conducting area with the big outputization of power inverter the electric connection structure of increase but lossless flexibility, and energy Suitable for vehicle-mounted harsh vibration condition.

Technical scheme applied to solve the technical problem

The connection structure of power inverter of the invention is a kind of connection structure of vehicle-mounted power inverter, packet It includes: the framework of power inverter；Electrical connection section, the electrical connection section and framework are mechanically connected, and are turned for carrying out electric power Changing device is electrically connected with external device (ED)；And power inverter is electrically connected by electric conductor, the electric conductor with electrical connection section, Framework and electrical connection section are mechanically connected via vibration-proof structure, and electric conductor has the opposite position that can follow framework and electrical connection section The flexibility of shifting.

Invention effect

According to the present invention, the vibration-proof structure for being suitable for severe vibration condition can not only be set to mechanical link, also Electrical connection section can be positioned in.In addition, being able to achieve the mitigation of Product Precision by the flexibility of vibration-proof structure, and cancel electrical power conversion Therefore operation in device can simplify manufacturing management, can reduce manufacturing cost.
