Description
Technical Field
The present invention relates to a mounting structure of a vehicle electric compressor.
Background
In the related art, a motor-driven compressor may be mounted on a vehicle body of a vehicle as a part of an air conditioning system for the vehicle. The electric compressor may be fixed to a vehicle driving part having a casing with high rigidity, such as an engine (engine) or a motor (motor), thereby reinforcing the rigidity of the entire structure. As the weight of the vehicle (for example, an electric vehicle) is developed, the impact load to which the electric compressor is subjected when the vehicle collides increases. In this case, if the rigidity of the entire structure is further increased to protect a high-voltage portion such as an inverter (inverter) in the motor compressor, for example, the rigidity of a housing, a mounting boss, a fixing bracket, or the like of the motor compressor is increased, or a protector is provided at a position corresponding to the high-voltage portion, the entire structure becomes large and the cost is increased.

Detailed Description
Reference will now be made in detail to exemplary embodiments of the utility model, examples of which are illustrated in the accompanying drawings. Fig. 1 is a partial schematic view of a mounting structure of an electric compressor for a vehicle according to an embodiment of the present invention applied to a vehicle body, fig. 2 is a plan schematic view of the mounting structure of the electric compressor for a vehicle shown in fig. 1, and fig. 3 is a cross-sectional schematic view of the mounting structure of the electric compressor for a vehicle shown in fig. 2 at a tangent line a-a. A specific composition of the motor compressor mounting structure 100 for a vehicle according to an embodiment of the present invention and an application thereof to the vehicle 50 (shown in fig. 1) will be described below with reference to fig. 1 to 3, but the present invention is not limited thereto.
Referring to fig. 1 to 3, in the present embodiment, the mounting structure 100 of the electric compressor for a vehicle includes a vehicle driving part 110, an electric compressor 120, and a bracket 130. The vehicle drive unit 110 is provided on the vehicle body 52 of the vehicle 50. The electric compressor 120 is provided on the vehicle body 52, and is provided on the front side of the vehicle drive portion 110 in the vehicle front-rear direction (for example, the vehicle front direction Fr and the vehicle rear direction Rr shown in fig. 3). The bracket 130 is connected to the motor-driven compressor 120 to fix the motor-driven compressor 120 to the vehicle driving part 110.
Specifically, in the present embodiment, the vehicle drive unit 110 is a device for driving the vehicle 50, such as an engine or a motor, and generally has a casing having high rigidity. The vehicle driving unit 110 is provided on the vehicle body 52 of the vehicle 50, and is provided around the cross member 54 and the side member 56 in the bottom structure of the vehicle body 52, for example, but not limited thereto. The motor-driven compressor 120 is, for example, a motor-driven compressor for air conditioning used in an air conditioning system for a vehicle, and the bracket 130 is, for example, a fixing bracket made of aluminum, but the utility model is not limited thereto. Accordingly, the electric compressor 120 is fixed to the vehicle driving unit 110 having high rigidity via the bracket 130, and the rigidity of the entire structure of the vehicle electric compressor mounting structure 100 can be improved.
In the present embodiment, as shown in fig. 3, the electric compressor 120 includes a high-voltage portion 122 and a rigid portion 124 located around the high-voltage portion 122. The high-voltage portion 122 of the electric compressor 120 is, for example, an inverter, and the rigid portion 124 of the electric compressor 120 is, for example, a stator portion or a housing partition wall of the electric compressor 120 (in the drawings, the housing partition wall protruding outward of the electric compressor 120 is illustrated as the rigid portion 124). Therefore, the high voltage part 122 of the electric compressor 120 can be regarded as a part of the electric compressor 120 having a low rigidity, and if damaged, it is difficult to maintain the operation of the electric compressor 120. Accordingly, the rigid portion 124 of the electric compressor 120 can be regarded as a portion of the electric compressor 120 having high rigidity and can receive a large impact load.
Thus, in the present embodiment, in order to protect the high-voltage portion 122 of the electric compressor 120 when the electric compressor 120 receives a shock load, the electric compressor 120 is provided such that the rigid portion 124 faces the vehicle driving portion 110 and the high-voltage portion 122 faces the inside of the vehicle 50. That is, the rigid portion 124 is provided so as to face the rear side in the vehicle front-rear direction (for example, the vehicle rear direction Rr shown in fig. 3) while being interposed between the body of the vehicle drive portion 110 and the vehicle drive portion 110, and the high-voltage portion 122 is provided so as to face the inner side in the vehicle width direction (for example, the vehicle left direction L in the vehicle left direction L and the vehicle right direction R shown in fig. 1 to 3). This can prevent the impact load received by the vehicle 50 from the outside (for example, the vehicle right direction R or the vehicle front direction Fr) from being directly transmitted to the high-voltage portion 122.
Further, in the present embodiment, the vehicle electric compressor mounting structure 100 further includes a protector 140, and the protector 140 is disposed outside the electric compressor 120 and covers the high voltage portion 122 of the electric compressor 120. As shown in fig. 1 to 3, the protector 140 is provided on the front side of the electric compressor 120 in the vehicle front-rear direction (for example, the vehicle front direction Fr and the vehicle rear direction Rr shown in fig. 3), is fixed to the housing of the electric compressor 120 via a fixing member such as a bolt, for example, and covers the high-voltage portion 122 facing the inner side in the vehicle width direction (for example, the vehicle left direction L in fig. 1 to 3), that is, the protector 140 is provided on the front side of the electric compressor 120 to the left side. This can prevent the impact load received by the vehicle 50 from the outside (for example, in the vehicle front direction Fr) from being directly transmitted to the high-voltage portion 122. However, the present invention is not limited to the arrangement of the protection member 140, and it can be adjusted according to the requirement.
In the present embodiment, a part of the bracket 130 is disposed between the vehicle driving unit 110 and the electric compressor 120. For example, as shown in fig. 2 and 3, the bracket 130 has a supporting portion 132 and a fixing portion 134, wherein the electric compressor 120 is fixed on the supporting portion 132 of the bracket 130 by a fixing member such as a bolt, and the fixing portion 134 of the bracket 130 is fixed on the vehicle driving portion 110 by a fixing member such as a bolt. As such, the support portion 132 is provided between the vehicle driving portion 110 and the electric compressor 120 to support the electric compressor 120 from the rear side of the electric compressor 120 (e.g., the vehicle rear direction Rr in fig. 3). And, the fixing portion 134 extends from the supporting portion 132 to a side of the motor-driven compressor 120 to fix the motor-driven compressor 120 to the vehicle driving portion 110. Therefore, the bracket 130 disposed between the vehicle driving unit 110 and the electric compressor 120, or the mounting boss or the like on the bracket 130 are used to secure the mounting strength of each component in a normal state.
In addition, in the present embodiment, as shown in fig. 3, the load input portion 126 of the electric compressor 120 (for example, a portion of the electric compressor 120 corresponding to the protector 140), the rigid portion 124 of the electric compressor 120 (for example, a stator portion or a housing partition wall of the electric compressor 120), and the load transmission portion 112 of the vehicle driving portion 110 (for example, a portion of the vehicle driving portion 110 corresponding to the rigid portion 124) are aligned along a straight line (an axis D shown in fig. 3) in the load input direction, and the high voltage portion 122 of the electric compressor 120 is located at a position other than the straight line (the axis D shown in fig. 3).
As described above, in the present embodiment, as shown in fig. 3, when the vehicle 50 collides and the vehicle electric compressor mounting structure 100 receives an impact load (impact load F shown in fig. 3), the impact load F is transmitted in a straight line (axis D shown in fig. 3) in the load input direction from the load input portion 126 of the electric compressor 120, the rigid portion 124 of the electric compressor 120, and the load transmission portion 112 of the vehicle driving portion 110. Therefore, the bracket 130 disposed between the vehicle driving unit 110 and the electric compressor 120, the mounting boss on the bracket 130, and the like are broken to absorb the impact energy, and the rigid portion 124 of the electric compressor 120 abuts against the vehicle driving unit 110 to disperse the impact energy to the vehicle driving unit 110 having a highly rigid housing, thereby protecting the high voltage portion 122 of the electric compressor 120. Accordingly, the vehicle electric compressor mounting structure 100 can protect the high-voltage portion 122 of the electric compressor 120 and avoid an increase in the size of the structure when receiving the impact load F.
As described above, in the vehicle electric compressor mounting structure according to the present invention, the vehicle driving unit is provided on the vehicle body, the electric compressor is provided on the front side of the vehicle driving unit in the vehicle front-rear direction, and the bracket fixes the electric compressor to the vehicle driving unit, wherein the electric compressor has the high-voltage portion and the rigid portion located around the high-voltage portion, the electric compressor is provided such that the rigid portion faces the vehicle driving unit, and a part of the bracket is disposed between the vehicle driving unit and the electric compressor. Preferably, the mounting structure of the electric compressor for a vehicle further includes a protector disposed at an outer side of the electric compressor and covering the high voltage portion of the electric compressor. In this way, when the vehicle collides and the vehicle electric compressor mounting structure receives an impact load, the bracket disposed between the vehicle driving unit and the electric compressor, the mounting boss on the bracket, and the like are broken to absorb impact energy, and the rigid portion of the electric compressor abuts against the vehicle driving unit to disperse the impact energy to the vehicle driving unit having the casing with high rigidity, thereby protecting the high-voltage portion of the electric compressor. Accordingly, the vehicle electric compressor mounting structure according to the present invention can protect the high-voltage portion of the electric compressor and avoid an increase in the size of the structure when receiving an impact load.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
