  As described above, in order to fix the compressor for the vehicle air conditioner from the side to the engine or the like, the side surface of the compressor is provided with a bolt hole. However, in the case of a vehicle without an engine such as an electric vehicle, it is necessary to install it on the floor.

In addition, when mounting on a vehicle, unlike a refrigerator or the like, a vibration load of the vehicle is applied in addition to the vibration of the compressor itself, so that a vibration isolating structure with higher performance is required. For this reason, the vibration-proof structure of Patent Document 1 causes a problem in vibration-proof performance. The present invention has been made paying attention to such problems existing in the conventional technology, and its purpose is applied to the engine. It is an object of the present invention to provide a compressor mounting structure in which a compressor for a vehicle air conditioner that cannot be mounted is mounted so as to exhibit high vibration isolation performance.

  Descriptions of patent documents listed as prior art can be introduced or incorporated by reference as explanations of technical elements described in this specification.

In order to achieve the above object, the present invention employs the following technical means. That is, in the invention described in the claims, the compressor (1) having a plurality of mounting holes (3, 4, 5) on the side surface is mounted on the vehicle floor (2) in a direction orthogonal to the side surface. In the mounting structure, a compressor-shaped bracket (6, 7) having a bent shape to be fastened to the plurality of mounting holes (4, 5) is provided on the vehicle floor (2) side of the compressor (1). A vehicle side bracket (8, 9) is provided between the vehicle floor (2) and the compressor side bracket (6, 7), and the compressor side bracket (6, 7) and the vehicle side bracket ( A plurality of first anti-vibration rubbers (11, 12) between 8, 9),
A plurality of second anti-vibration rubbers (16, 17) are provided between the vehicle side brackets (8, 9) and the vehicle floor (2), and the compressor side brackets (6, 7), the first The anti-vibration rubber (11, 12), the vehicle side brackets (8, 9), and the second anti-vibration rubber (16, 17) are arranged in a direction perpendicular to the longitudinal direction of the compressor (1). A pair is provided so as to face each other, and space portions (20a, 20b) are formed between the pair of compressor side brackets (6, 7) and between the pair of vehicle side brackets (8, 9), respectively. It is characterized by being.

  According to the present invention, since the first anti-vibration rubber and the second anti-vibration rubber that receive the weight of the compressor in series are provided to form the double anti-vibration structure, the anti-vibration performance is improved as compared with the single anti-vibration structure. The compressor used for the vehicle air conditioner can be attached to the vehicle floor surface with high anti-vibration performance. Further, since the space portions are formed between the pair of compressor side brackets and the pair of vehicle side brackets facing each other, the weights of the compressor side bracket and the vehicle side bracket can be reduced. By reducing the weight of these brackets, damage to the rubber can be reduced even if the rubber hardness of the vibration-proof rubber is softened. In particular, since the total weight of the bracket applied to the second vibration isolating rubber is reduced, the burden on the second vibration isolating rubber can be reduced and the durability can be improved.

  The central axes of the plurality of first vibration isolating rubbers (11, 12) facing each other in the direction perpendicular to the longitudinal direction of the compressor (1) are directed toward the center of gravity of the compressor (1). Thus, the portion of the vehicle side bracket (8, 9) that is inclined with respect to a line perpendicular to the vehicle floor surface (2) and receives the first vibration isolating rubber (11, 12) is the vehicle floor surface. It is characterized by being formed as an inclined surface (8k) inclined with respect to (2).

  According to this invention, when viewed from the front of the compressor, the first vibration isolating rubber can receive a load from the center of gravity to the first vibration isolating rubber on a surface substantially orthogonal to the load. Anti-vibration rubber is strong against longitudinal loads along the central axis, but weak against shear loads due to lateral loads. Therefore, since the first vibration-proof rubber receives vibrations of the compressor by a longitudinal load, the amount of the vibration-proof rubber can be minimized, and the compressor mounting structure can be configured at low cost.

  A plurality of modes for carrying out the present invention will be described below with reference to the drawings. In each embodiment, parts corresponding to the matters described in the preceding embodiment may be denoted by the same reference numerals, and redundant description may be omitted. When only a part of the configuration is described in each mode, the other modes described above can be applied to the other parts of the configuration.

  Not only combinations of parts that clearly indicate that the combination is possible in each embodiment, but also the embodiments are partially combined even if they are not clearly specified unless there is a problem with the combination. It is also possible.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS. In FIG. 1, a compressor 1 is an electric compressor in which an electric motor part and a compressor part driven by the electric motor part are integrated. The compressor 1 is mounted on a vehicle floor 2 of a motor compartment of an electric vehicle (a section in which an electric vehicle drive motor or the like is mounted). The compressor 1 is usually provided with a first bolt hole 3 (FIG. 2), a second bolt hole 4, and a third bolt hole 5 that form mounting holes for mounting to the engine. In this embodiment, the first bolt hole 3 is not used. 4N and 5N are nuts.

  First, as shown in FIGS. 1 and 2, two opposing L-shaped compressor-side brackets 6 and 7 and two plate-like vehicle-side brackets 8 and 9 are connected to a first anti-vibration rubber 11, 12 is fixed with four bolts and nuts. The first anti-vibration rubber 12 is a generic term for the first anti-vibration rubbers 12a and 12b in FIG. 2, and the same applies to the first anti-vibration rubber 11. Further, 11N1 and 11N2 are nuts, and bolts are provided in the first vibration isolating rubber 11 so as to connect these nuts 11N1 and 11N2.

  Next, as shown in FIGS. 1 and 2, the two compressor side brackets 6 and 7 are fixed to the second bolt hole 4 and the third bolt hole 5 at four locations with bolts and nuts. Finally, the vehicle side brackets 8 and 9 are fixed to the vehicle floor 2 with four bolts and nuts via the second vibration isolating rubbers 16 and 17.

  In this way, the brackets are divided into the compressor side brackets 6 and 7 and the vehicle side brackets 8 and 9, and the compressor side brackets 6 and 7 and the vehicle side brackets 8 and 9 are also divided into a pair. Therefore, the bracket can be reduced in weight as compared with a U-shaped integrated compressor side bracket (comparative example described later) and a single plate integrated vehicle side bracket.

  With this weight reduction, when the first anti-vibration rubbers 11 and 12 and the second anti-vibration rubbers 16 and 17 are used for the double anti-vibration, the lower second anti-vibration rubbers 16 and 17 are softened. Even so, rubber wear can be reduced. At the same time, both the compressor 1 and the brackets 6 to 9 do not require strict control of the size of the mounting holes or the like as compared with the U-shaped integrated compressor side bracket and the single plate integrated vehicle side bracket. Assembling becomes possible and the cost is reduced. 1 to 3, bolts and nuts are all attached to the compressor 1 and the compressor side brackets 6 and 7, and to the first vibration isolation rubbers 11 and 12 and the second vibration isolation rubbers 16 and 17, respectively. It is done using.

  Next, a part of the vehicle air conditioner in which the compressor 1 is used will be described with reference to FIG. The vehicle air conditioner is configured to control an air conditioning unit 41 that air-conditions a vehicle interior by an air conditioner ECU (not shown). This vehicle air conditioner controls the refrigerant flow of the refrigeration cycle 42 to air-condition the passenger compartment.

  The air conditioning unit 41 includes an air conditioning case 44 that is disposed in front of the vehicle interior of the vehicle and through which the blown air passes. In the air conditioning case 44, an air intake is formed on one side on the left side in FIG. 4, and a plurality of air outlets through which air toward the vehicle interior passes are formed on the other side. The air conditioning case 44 has a ventilation path 44a through which the blown air passes between the air intake and the air outlet. A blower unit 45 is provided upstream of the air conditioning case 44 (left side in FIG. 4).

  The blower unit 45 (air conditioner blower) includes an inside / outside air switching mechanism (also referred to as an inside / outside air switching door) 46 and a blower 47 having a centrifugal fan 43. The inside / outside air switching door 46 is driven by an actuator such as a servo motor, and constitutes a suction port switching means for changing the opening between the inside air suction port 48a and the outside air suction port 48b which are air intake ports.

  The inside air suction port 48a of the blower unit 45 sucks in the cabin air. The blower 47 is a centrifugal blower that is rotationally driven by a blower motor controlled by a blower drive circuit (not shown) and generates an air flow toward the vehicle interior in the air conditioning case 44. The blower 47 has a function of changing the amount of conditioned air blown out from each outlet, which will be described later, toward the passenger compartment.

  The air-conditioning case 44 is provided with an evaporator 51 that forms an air-conditioning heat exchanger that cools the air blown from the blower unit 45 to air-conditioning air and sends it to a plurality of outlets. The evaporator 51 functions as a cooling heat exchanger that adjusts (cools) the temperature of the conditioned air that passes through the air conditioning case 44 and moves toward the vehicle interior using a refrigerant.

  The evaporator 51 is a component of the refrigeration cycle 42. A compressor 1c is connected to a compressor 1c that converts a direct current of a battery (not shown) into a three-phase alternating current by an inverter 1a and is driven by an electric motor 1b to which the three-phase alternating current is input, sucks a refrigerant, compresses and discharges the refrigerant. Contained within.

  The refrigeration cycle 42 also has a condenser (condenser) 52 that condenses and liquefies the refrigerant discharged from the compressor 1, a receiver 53 that gas-liquid separates the liquid refrigerant flowing from the condenser 52, and flows out from the receiver 53. An expansion valve 54 for adiabatically expanding the liquid refrigerant and the evaporator 51 for evaporating and evaporating the gas-liquid two-phase refrigerant flowing from the expansion valve 54 are included.

  When the rotational power of the electric motor 1b is transmitted to the compressor 1c and the air cooling action is performed by the evaporator 51, and the rotation of the electric motor 1b is stopped (off), the refrigerant is not discharged by the compressor 1, and the evaporator 51 The air cooling action by is stopped. Moreover, although the compression part 1c driven with the electric motor 1b consists of what is called a scroll type, you may use what is called a swash plate type.

  Capacitor 52 is disposed in a place where it is easy to receive traveling wind generated when the electric vehicle travels, and performs outdoor heat exchange for exchanging heat between the refrigerant flowing inside and the outside air blown by outdoor fan 55 and the traveling wind. Make up the vessel.

  On the most downstream side (right side in FIG. 4) of the air-conditioning case 44, a defroster opening, a face opening, and a foot opening that form a blower outlet switching unit (not shown) are formed. Inside each air outlet, two air outlet switching doors are rotatably attached.

  An electric heater is provided on the downstream side of the evaporator 51. The electric heater is a heater wire made of PTC or nichrome wire, and the heater wire is connected in parallel between the power source and the ground.

  When the compressor 1 compresses and sends out the refrigerant, the compressor 1 is accompanied by rotational fluctuations that cause vibrations around the rotation axis of the compressor 1, and vibration loads in a direction parallel to and perpendicular to the vehicle floor 2 (FIG. 1) It is transmitted to the vehicle floor 2 through the first anti-vibration rubbers 11 and 12 and the second anti-vibration rubbers 16 and 17.

(Operational effects of the first embodiment)
First, the compressor mounting structure shown in FIG. 5 as a comparative example will be described. In this comparative example, an attachment structure of the compressor 1 in which the compressor 1 having a plurality of attachment holes 3, 4, 5 on the side surface is mounted on the vehicle floor 2 in a direction orthogonal to the side surface is shown. On the vehicle floor 2 side of the compressor 1, there is provided an integrated compressor side bracket 67 having a U-shaped bent shape that is fastened to a plurality of attachments 4 and 5. Further, an integrated vehicle side bracket 89 made of a single flat plate is provided between the vehicle floor 2 and the integrated compressor side bracket 67.

  A plurality of first anti-vibration rubbers 11 and 12 are distributed between the integrated compressor side bracket 67 and the integrated vehicle side bracket 89 in the longitudinal direction of the compressor 1 (perpendicular to the plane of FIG. 1). Yes. The first anti-vibration rubbers 11 and 12 are shifted in the mounting position, and a plurality of second anti-vibration rubbers 16 and 17 are arranged between the integrated vehicle side bracket 89 and the vehicle floor 2 in the longitudinal direction of the compressor 1. Are distributed.

  According to this, since the first anti-vibration rubbers 11 and 12 and the second anti-vibration rubbers 16 and 17 that receive the weight of the compressor 1 in series are provided to form the double anti-vibration structure, compared with the single anti-vibration structure. Although the vibration isolating performance can be increased and the compressor 1 used in the vehicle air conditioner for a vehicle without an engine can be mounted with high vibration isolating performance, the weights of the brackets 67 and 89 are increased. Accordingly, the weights of the brackets 67 and 89 must increase the hardness of the rubbers of the first anti-vibration rubbers 11 and 12 and the second anti-vibration rubbers 16 and 17, and the anti-vibration performance is limited.

  Next, the first embodiment in which the comparative example is improved will be described. In the first embodiment, as shown in FIG. 1, a compressor 1 mounting structure in which a compressor 1 having a plurality of mounting holes 3, 4, and 5 on a side surface is mounted on a vehicle floor 2 in a direction orthogonal to the side surface. providing. Bent compressor-side brackets (also referred to as compressor-side brackets) 6 and 7 (FIG. 1) that are fastened to a plurality of mounting holes 4 and 5 are provided on the vehicle floor 2 side of the compressor 1. The compressor side brackets 6 and 7 are made of brackets which are opposed to each other and a space portion 20a is formed therebetween. Vehicle side brackets 8 and 9 are provided between the vehicle floor 2 and the compressor side brackets 6 and 7. The vehicle side brackets 8 and 9 are also made of brackets which are opposed to each other and a space portion 20b is formed therebetween.

  Between the compressor side brackets 6 and 7 and the vehicle side brackets 8 and 9, a plurality of first anti-vibration rubbers 11 and 12 are provided dispersed in the longitudinal direction of the compressor 1 (the depth direction in FIG. 1). Yes. The first anti-vibration rubbers 11 and 12 are shifted from each other in the mounting position, and a plurality of second anti-vibration rubbers 16 and 17 are disposed between the vehicle side brackets 8 and 9 and the vehicle floor 2 side. Distributed in the direction.

  According to this, since the first anti-vibration rubbers 11 and 12 and the second anti-vibration rubbers 16 and 17 that receive the weight of the compressor 1 in series are provided to form the double anti-vibration structure, compared with the single anti-vibration structure. Thus, the vibration isolating performance can be enhanced, and the compressor 1 used for the vehicle air conditioner of a vehicle that is quiet as a whole without an engine can be mounted with high vibration isolating performance.

  Further, since the second vibration isolating rubbers 16 and 17 are provided by shifting the mounting position from the first anti-vibration rubbers 11 and 12, the nuts or the like as the mounting members of the respective anti-vibration rubbers 11 to 17 do not interfere with each other. And the dimension of the up-down direction which connects the attachment hole 3 and a floor surface can be made small.

  In addition, the compressor side brackets 6 and 7, the first vibration isolation rubbers 11 and 12, the vehicle side brackets 8 and 9, and the second vibration isolation rubbers 16 and 17 are oriented at right angles to the longitudinal direction of the compressor 1. The space portions 20a and 20b are formed between the pair of compressor side brackets 6 and 7 and between the pair of vehicle side brackets 8 and 9, respectively.

  Thus, since the space parts 20a and 20b are formed, the weight of each of the compressor side brackets 6 and 7 and the vehicle side brackets 8 and 9 can be reduced. By reducing the weight of the brackets 6 to 9, even if the rubber hardness of the first second anti-vibration rubbers 11 to 17 is reduced, damage to the rubber can be reduced. In particular, since the total weight of the brackets 6 to 9 applied to the second anti-vibration rubbers 16 and 17 is reduced, the burden on the second anti-vibration rubbers 16 and 17 can be reduced, and the durability is excellent.

  Further, since the compressor 1 is used in common with a compressor mounted on a vehicle on which an engine is mounted, a plurality of mounting holes 4 and 5 (FIG. 2) are provided on the lower side, which is the floor side of the side surface of the compressor 1. Provided, at least one unused mounting hole 3 is provided above the side surface of the compressor 1.

  According to this, since at least one unused mounting hole 3 is provided on the upper side of the side surface of the compressor 1, the structure of the compressor can be shared even in the case of a vehicle in which the compressor 1 is placed on the engine.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. In the following embodiments, the same components as those in the first embodiment described above are denoted by the same reference numerals, description thereof will be omitted, and different configurations and features will be described. In the first embodiment, the anti-vibration rubber is arranged perpendicular to the vehicle floor surface. However, in the second embodiment, the anti-vibration rubber is arranged along the vibration load direction.

  6 to 8, first, the first vibration isolating rubbers 11 and 12 are fixed to the two compressor side brackets 6 and 7 and the two vehicle side brackets 8 and 9 with bolts and nuts at four locations. Next, the two compressor side brackets 6 and 7 are fixed to the second bolt hole 4 (FIG. 8) and the third bolt hole 5 at four locations with bolts and nuts.

  Next, the vehicle side brackets 8 and 9 and the second anti-vibration rubbers 16 and 17 are fixed to the vehicle floor 2 with four bolts and nuts. The first anti-vibration rubbers 11 and 12 are provided with an inclination θ1 of, for example, 28 degrees toward the center of gravity of the compressor 1.

  As shown in FIG. 7, the plate-like vehicle-side bracket 8 is inclined in both the short-side direction Y71 and the long-side direction Y72 with respect to the flat surface portion 8h to which the second vibration-proof rubbers 16 and 17 are attached by pressing or the like. An inclined surface 8k is provided. A bolt insertion hole 11h for receiving and attaching the first vibration isolating rubber 11 is formed in the inclined surface 8k. The first anti-vibration rubbers 11 and 12 can be attached by being inclined by the angles θ1 and θ2 toward the center of gravity of the compressor 1 by the inclined surface 8k.

  The first anti-vibration rubbers 11 and 12 and the second anti-vibration rubbers 16 and 17 are strong against the load in the central axis direction of the anti-vibration rubbers 11 to 17 but weak against the shear load perpendicular to the central axis. In the second embodiment, since the direction of the central axis of the first vibration isolating rubbers 11 and 12 can be arranged closer to the load direction, the amount of the first anti-vibration rubbers 11 and 12 can be reduced and the cost can be reduced. You can configure the system.

(Operational effect of the second embodiment)
The central axes of the pair of first anti-vibration rubbers 11 and 12 facing each other in the direction perpendicular to the longitudinal direction of the compressor 1 are inclined with respect to a line perpendicular to the vehicle floor 2 so as to be directed to the center of gravity of the compressor 1. ing. Further, the portions of the vehicle side brackets 8 and 9 that receive the inclined first anti-vibration rubbers 11 and 12 are formed as an inclined surface 8 k that is inclined with respect to the vehicle floor surface 2.

  According to this, the first anti-vibration rubbers 11, 12 can receive the load from the center of gravity to the first anti-vibration rubbers 11, 12 on the surface substantially orthogonal to the load. Anti-vibration rubber is strong against longitudinal loads along the central axis, but weak against shear loads due to lateral loads. Since the first anti-vibration rubbers 11 and 12 receive the vibration of the compressor 1 mainly by a longitudinal load, the amount of the anti-vibration rubber can be minimized and the mounting structure of the compressor can be configured at low cost.

  Further, as shown in FIG. 8, each of the pair of first anti-vibration rubbers 12 a and 12 b (same for 11 a and 11 b) facing each other in the longitudinal direction of the compressor 1 has its center axis approaching the center of gravity direction of the compressor 1. As described above, the pair of first vibration isolating rubbers 12 a and 12 b are provided to be inclined with respect to a line perpendicular to the vehicle floor surface 2.

  According to this, the pair of first anti-vibration rubbers 12a and 12b opposed to the longitudinal direction of the compressor 1 receives the vibration of the compressor 1 mainly by a longitudinal load even when viewed from the lateral direction of the compressor 1. Therefore, the amount of the anti-vibration rubber can be reduced, and the compressor mounting structure can be configured at low cost.

  Next, the vehicle-side bracket 8 (same for 9) is an inclined surface inclined in the short-side direction Y71 of the vehicle-side bracket 8 and (9) with respect to the flat surface portion 8h to which the second vibration isolating rubber 16 (17) is attached. 8k.

The rubbers 11, (12) can be attached so that the respective central axes are directed in the direction of the center of gravity of the compressor 1.

  Further, the vehicle side brackets 8 and 9 are inclined toward both the long side direction Y72 and the short side direction Y71 of the vehicle side brackets 8 and 9 with respect to the flat surface portion 8h to which the second vibration isolation rubbers 16 and 17 are attached. It has an inclined surface 8k. A bolt insertion hole 11h for attaching the first vibration isolating rubbers 11 and 12 is formed in the inclined surface 8k.

  According to this, since it has the inclined surface 8k inclined on both sides of the long side direction Y72 and the short side direction Y71 with respect to the flat surface part 8h to which the second vibration isolating rubber 16, 17 is attached, this inclined surface 8k.

You may apply this invention to the compressor of an apparatus.

  Although it was applied to a vehicle air conditioner for a vehicle without an engine, it has an engine, but for some reason, for example, only a small engine for power generation is mounted on the vehicle, or the vibration isolation function of the engine and the compressor is individualized. The present invention may be applied to a vehicle air conditioner for a vehicle in which a compressor cannot be attached to the side of the engine because it is necessary to enhance an anti-vibration function or a damper function. Furthermore, the inclined surface 8k in FIG. 7 is effective even when it is inclined toward only one of the short side direction Y71 and the long side direction Y72.
