Description

[Technical Field]

[0001] The present invention relates to a grip for a handlebar provided on a motorcycle, snowmobile, or the like. [Background technology]

[0002] Some handle grips on the handlebars of motorcycles and the like have built-in heaters to warm the gripping hands. Some such handle grips are also known to be equipped with temperature sensors to control the amount of heat generated by the heater. When such a temperature sensor is assembled in an internal housing made of resin and then molded with synthetic rubber, the flow of the rubber can cause the temperature sensor to be damaged or displaced. To address this issue, a technique is known in which a recess is formed in the outer peripheral surface of the internal housing, into which the temperature sensor is fitted (see, for example, Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-185748 Summary of the Invention [Problem to be solved by the invention]

[0004] Even when the temperature sensor is fitted into the recess of the internal housing as described above, the temperature sensor and electric wires are exposed to high temperatures during the rubber molding process, so the temperature sensor and electric wires must be designed to withstand such high temperatures.

[0005] The present invention has been made in view of the above points, and aims to make it possible to apply the present invention to temperature sensors and electric wires with low heat resistance. [Means for solving the problem]

[0006] To achieve the above objectives, The present invention provides a cylindrical inner housing; a heating element provided on the outer periphery of the inner housing; a covering member that covers the inner housing and the heating element; A handle grip having moreover, A temperature sensor; a tray for accommodating the temperature sensor; and The tray housing the temperature sensor is inserted into a tray insertion hole formed in the inner housing and / or the covering member.

[0007] This allows the temperature sensor to be attached by inserting a tray containing the temperature sensor into the tray insertion hole after molding the covering member, making it possible to use temperature sensors and electric wires with low heat resistance. [Effects of the Invention]

[0008] The present invention can be applied to temperature sensors and wires with low heat resistance. [Brief explanation of the drawings]

[Figure 3] 10A-10C are end views showing examples of holes formed in the inner housing and / or the covering member. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0011] As shown in Fig. 1, the handle grip 100 is configured by wrapping a heating element 120 around the outer periphery of a cylindrical internal housing 110 (grip core), and molding the heating element 120 with a covering member 130 made of synthetic rubber or the like. The internal housing 110 is formed from, for example, flexible rubber or resin. The heating element 120 is configured to have a predetermined resistance value and is made of a narrow strip of metal foil made from, for example, stainless steel foil or copper foil.

[0012] A groove 111 extending in the longitudinal direction of the handle grip 100 is formed on the outer peripheral surface of the inner housing 110, and a groove 131 extending in the longitudinal direction of the handle grip 100 is formed on the inner peripheral surface of the covering member 130. The groove 111 and the groove 131 form a tray insertion hole 160 into which the tray 150 is inserted.

[0013] 2, the tray 150 is inserted into the tray insertion hole 160 with the temperature sensor 140 attached, so that the temperature sensor 140 can be attached or replaced after the covering member 130 is molded. More specifically, a recess 151 is formed in the longitudinal direction of the tray 150, and the temperature sensor 140 is fitted in the recess 151. The temperature sensor 140 is configured by connecting lead wires 141 and 142 to a detection element 143 formed of a thermistor or the like. The lead wires 141 and 142 are fitted, for example, between the inner wall of the recess 151 of the tray 150 and the protrusion 152.

[0014] Here, the recess 151 and protrusion 152 of the tray 150 may be formed in a shape that fits the temperature sensor 140, thereby suppressing movement of the temperature sensor 140 inside the tray and making it easier to reduce detection variations. To achieve a shape that fits the detection element 143 and the lead wires 141 and 142, it is not necessary to provide the protrusion 152; instead, a recess into which the detection element 143 fits may be formed. The detection element 143 and the like may also be fixed with an adhesive or the like. The adhesive may have a high thermal conductivity to improve temperature detection performance. From the viewpoint of detection performance, a filler with a high thermal conductivity may be used instead of an adhesive.

[0015] As described above, by attaching the temperature sensor 140 to the tray 150, the effects of temperature and flow pressure can be avoided when molding the covering member 130, and a temperature sensor 140 (detection element 143 and lead wires 141 and 142) with low heat resistance can be easily used. Furthermore, misalignment of the temperature sensor 140 can be easily prevented, which easily improves the accuracy of temperature detection in the handle grip 100. Furthermore, if the temperature sensor 140 is fitted into the recess 151 of the tray 150, even if a pressing force is applied from the outside of the covering member 130, the force acting on the temperature sensor 140 is easily reduced. This makes it possible to prevent damage to the detection element 143 and breakage of the lead wires 141 and 142, as well as to easily prevent a reduction in the lifespan of the temperature sensor 140. Furthermore, since the temperature sensor 140 can be easily positioned without having to be fixed to the inner housing 110 with adhesive tape or the like, the manufacturing process can be easily simplified.

[0016] Furthermore, since the temperature sensor 140 can be attached or replaced after the covering member 130 has been molded, workability can be improved and the life of the handle grip 100 can be extended.

[0017] (Variation) The tray insertion hole 160 into which the tray 150 is inserted is not limited to being constituted by a groove 111 formed in the inner housing 110 and a groove 131 formed in the covering member 130. For example, as shown in Fig. 3(a), the groove 111 may be formed only in the inner housing 110, or as shown in Fig. 3(b), the groove 131 may be formed only in the covering member 130. Furthermore, as shown in Fig. 3(c), the tray insertion hole 160 may be formed only in the inner housing 110, or the tray insertion hole 160 may be formed only in the covering member 130. This can facilitate molding of the covering member 130, eliminate the need for an insert during molding, and facilitate assembly of the heating element 120. [Explanation of symbols]
