Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a vehicle air conditioner equipped with an outside temperature sensor.

0002

[Conventional technology]

Generally, an air conditioner for an automobile is provided with an outside temperature sensor that detects outside temperature. For example, as shown in FIG. 12, the conventional outside temperature sensor 101 has a A sensor unit 103 equipped with a thermistor 102 whose electrical resistance changes when A lead wire 105 electrically connected to the air conditioner 102 and a lead wire 105 connected to the air conditioner main A connector portion 104 connected to the body side is provided. Here, the sensor section 103 is fixed to the bracket 106 using screws or the like.

0003 As shown in FIG. 13, the sensor section 103 of the outside temperature sensor 101 Attach the bracket 106 to the mounting portion 1 formed at the front end of the automobile C using a screw 107. 08, it is attached to the automobile C.

0004

[Problem that the idea aims to solve]

However, the conventional outside temperature sensor 101 as shown in FIG. 12 has relatively few components. Since there are many points, the structure becomes larger and the manufacturing cost increases. There is a problem. Also, attach the bracket 106 (sensor part 103) to the mounting part with the screw 107. There is a problem that it takes time and effort to attach it to 108. In addition, the outside temperature sensor When the sensor 101 is attached to the car C, the connector part 104 or the lead wire 10 There is a problem that 5 is suspended in the air and its position is unstable.

[0005] Therefore, as shown in FIGS. 14 and 15, the connector part 104' is connected to the bracket 1. 06, and fix the connector part 104' or the lead wire 105. An outside temperature sensor 101' has been proposed. However, it takes Even in the conventional outside temperature sensor 101', the number of parts is still large and the manufacturing cost is high. There is a problem with getting stuck. Also, the attachment of the bracket 106 to the automobile body The work is not reduced in any way.

[0006] The present invention was made in order to solve the above-mentioned conventional problems, and it can be easily A vehicle equipped with an inexpensive and compact outside temperature sensor that can be attached to the car body. The purpose is to provide air conditioning equipment for vehicles.

[0007]

[Means to solve the problem]

In order to achieve the above objectives, the present invention has developed a sensor that outputs a signal corresponding to the outside temperature. and a connector section that transfers the signal output from the sensor section to the air conditioner main body. In an automobile air conditioner equipped with an outside temperature sensor, the sensor part and the The sensor part and the connector part are integrally formed, and the combination of the sensor part and the connector part is attached to the car body. An automobile characterized in that an outside temperature sensor is provided with a structure to which the sensor is attached. Provides air conditioning equipment for

[0008]

【Example】

Hereinafter, embodiments of the present invention will be described in detail. <First example> As shown in FIGS. 1 to 5, the plastic main body 1 of the outside temperature sensor S includes: Clip part 2 for attaching the outside temperature sensor S to the vehicle body side and the outside temperature sensor S Connector part 3 for connecting to the connection terminal (not shown) on the air conditioner side and detecting the outside temperature. A sensor section 4 for emitting light is integrally formed. Note that the clip portion 2 is defined in claim 1. Corresponds to the structure described. In this way, the clip part 2, the connector part 3 and the Since the external temperature sensor S is integrally formed with the In addition to reducing manufacturing costs, the outside temperature sensor S has also been made significantly more compact. ing.

[0009] A thermistor 5 that converts the outside temperature into an electrical resistance value is arranged inside the sensor section 4. There is. This thermistor 5 is a normal wire whose resistance value decreases as the outside temperature rises. It is a shaped element and is provided with two terminals (not shown). This thermis The sensor 5 is protected by an epoxy resin packing 6 inside the sensor section 4. It is. Although not shown in detail, both terminals of the thermistor 5 have a husband Conductive wires 7a and 7b are connected to each other. Also, from the sensor section 4 to the main body section 1 in the longitudinal direction ( It penetrates in the left-right direction (in Fig. 1) and protrudes into the hollow part 3a formed in the connector part 3. Two terminals 8a and 8b are provided. Here, conductor 7a is the terminal 8a, and conductor 7b is connected to terminal 8b.

0010 Although not shown, there is a connection terminal on the air conditioner main body side in the hollow part 3a of the connector part 3. When the terminals 8a and 8b are inserted, the terminals 8a and 8b are respectively connected to the control unit of the air conditioner. It is designed to be electrically connected to the knit. In this way, the thermistor 5 is connected to the control unit, the control unit will Convert the resistance value of the thermistor 5 corresponding to the outside temperature into a voltage, and apply various voltages corresponding to the outside temperature. It is used as one of the control information for air conditioning control.

[0011] In this way, the thermistor 5 is connected to the Since it is connected to terminals 8a and 8b (connector part 3), it can be used as a conventional outside temperature sensor. There is no need to provide lead wires (see FIGS. 12 and 14) as in the case of . therefore The number of parts is reduced, the outside temperature sensor S is made more compact, and the manufacturing cost is reduced. This reduces costs.

0012 By the way, the outside temperature sensor S is designed so that the clip part 2 is inserted into a hole formed on the car body side. It is attached to the vehicle body by inserting it into a section or a recess (not shown). Therefore, the work of mounting the outside temperature sensor S onto the vehicle body is greatly simplified. Also, a bracket (see Figures 12 and 14) is required as in the case of conventional outside temperature sensors. Since this is not necessary, the number of parts is further reduced, and manufacturing costs are further reduced.

[0013] <Second example> A second embodiment of the present invention will be described below with reference to FIGS. 6 to 11, but the emphasis of the explanation will be To avoid confusion, parts common to the first embodiment shown in FIGS. 1 to 5 are the same as those in the first embodiment. No. 1 is given and the explanation thereof is omitted, and only the parts that are different from the first embodiment will be explained. do.

[0014] As shown in Figures 6 to 11, in the second embodiment, the outside temperature sensor S' is installed on the vehicle body side. Insertion parts 11a and 11b for attachment are provided on the lower surface of the main body part 1. this The insertion portions 11a and 11b correspond to the structure described in claim 1. and, In the second embodiment, the insertion portions 11a and 11b are provided on a plate portion provided on the vehicle body side. (not shown) or the end of some existing plate-like member. Therefore, the outside temperature sensor S' is attached to the vehicle body. Therefore, the outside temperature The installation work of the S' on the car body is greatly simplified. In addition, the conventional outside temperature Of course, there is no need for brackets (see Figures 12 and 14) as in the case of sensors. There it is. The structure or function of other parts is the same as in the first embodiment. In addition, in the first and second embodiments, the outside temperature sensor is installed on the car body. A clip part or an insertion part is used as the structural part; Of course, it is not limited to.

[0015]

[Actions and effects of the idea]

According to the present invention, since the sensor part and the connector part are integrally formed, the outside temperature sensor The server is made more compact. It also eliminates the need for lead wires or brackets, The number of items is reduced and manufacturing costs are reduced. Furthermore, the structure part (clip part, Simply insert the plug into the hole or recess on the car body, and the outside temperature sensor will be activated. Since the sensor can be attached to the car body, installation of the outside temperature sensor is easy. Be stripped down.
