BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to devices, such as electric pots, mounted on a vehicle, and more particularly, to a vehicle installation structure of a vehicle-mounted device.

Conventional vehicle mounting mechanisms, such as carpots, are of the type of fixing the vehicle mounting mechanism to the vehicle body with screws or the like, or of the type of leaving the seat seat or hanging on the window frame without fixing the vehicle body at all. there was.

However, as it is necessary to move the vehicle mounting mechanism or fix it in any position or direction, it is very cumbersome because it is necessary to loosen the screw every time. In addition, if left on a seat, it is not preferable for safety, and there are cases where the vehicle mounting mechanism is lost. In addition, the type used to hang on the window frame had the drawback of being peeled off by the vibration of the body. In addition, the connection portion between the vehicle-mounted mechanism and the installation device thereof is worn out due to severe lateral vibration of the vehicle body, which shortens the service life of the mechanism.

In general, in an apparatus such as an electric pot, it is installed to be detachable at a proper position of the vehicle in consideration of water supply, but when it is installed in consideration of detachment, the vehicle exhibits a vibration state different from that of the vehicle body and the apparatus. In such a state, when both the device side connector and the vehicle body side connector are installed in a fixed state, both connectors will be in a different vibration state while the vehicle is being driven, and therefore, both connectors will be destroyed, and thus, both connectors themselves will be destroyed. There was a need for a power connection device that can cope with vibration sufficiently and maintain a stable connection for a long time. An object of the present invention is to provide an engagement device for vehicle-mounted equipment, such as a carpot, which is shockproof against vehicle vibration and is convenient to use.

Embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings. 1 is a base attached to an appropriate position of the vehicle body 2, 3 is an air pot having a boiling function and heat retention function, and the pot 3 is detachably installed on the base 1 by a magnetic body structure. 13 has a pair of electrode plates 14 as device side connectors installed in the bottom of the air pot 3. 15 is supported on the base 1 as a vehicle body side connector which forms the request | requirement 16 which the electrode plate 14 is fitted into, and provided the electrode holder 17 inside this request | requirement 16. 18 is a recess 19 formed on both sides of the vehicle body connector 15, which is a support recess placed on the base 1. The bent piece 20 of the tip is inserted into the recess 18, and the recess 18 is provided. The vehicle body side connector 15 is supported so that it can move to some extent up and down, left and right, and back and forth within the range permissible.

21 is a connecting tool installed on both sides of the vehicle body side connector 15, and is made of an elastic material, and adheres to both sides of the device side connector 13. 22 is a power cord.

When the support body 10 of the air pot 3 is fitted to the outer periphery of the engagement boss 6 on the base 1 by the above structure, the electrode plate 14 of the device side connector 13 will be connected to the vehicle body side connector 15. ) Is electrically connected to the electrode holder 17 therein, and the air pot 3 is supplied with power, while the connecting portion 21 is elastically connected to both sides of the device-side connector 13. The state of connection is maintained by clamping the connector 13 by engaging.

Therefore, while the base 1 and the air pot 3 on the side of the vehicle body 2 exhibit different vibration states while the vehicle is running, the body side connector 15 can move freely with respect to the base 1 within a certain range. By vibrating integrally with the device side connector 13, there is no fear that both connectors 13 and 15 will be destroyed by the difference in vibration, and the connection state can be reliably maintained.

Moreover, although the vehicle body side connector is movable in the above embodiment, the device side connector may be movable. In addition, the connector can be expected to have the same effect even when installed in the equipment side connector.

According to the configuration of the present invention as described above, it is very advantageous to provide a power connection device capable of exhibiting a stable connection state for a long time without being destroyed by vibration.

An embodiment of the present invention will be described with reference to Figs. 5 to 8, in which an engaging device of a vehicle mounting mechanism such as a carpot according to the present invention is mounted on a part of the vehicle 201 (inside surface of a door, etc.). 202 (metal mounting mounting plate 203 such as steel for supporting the carpot) is fixedly installed with screws 203a, and the engaging portion 204 is attached to one of the vehicle mounting mechanism 202 and the mounting plate 203. Is formed, and on the other side of the vehicle mounting mechanism 202 and the mounting plate 203, the engaging projection 205 which engages with the engaging recess 204 is protruded, and the engaging recess 204 The magnetic body 206 of a red body is clamped to a pair of steel plate 207 at the bottom part, and the said engagement protrusion part 205 is comprised from the adsorption material, such as iron materials, which adsorb | suck to the electromagnetic material 206. As shown in FIG.

The mounting plate 203 includes a protruding upper surface plate 203b protruding inside the vehicle body 201 and a fixing plate 203c fixed to the vehicle body 201 with a screw 203a and the positive plate 203b. , 203d of protrusion slanted walls 203c are integrally formed by press working or tightening processing (other components may be fixed by welding or the like).

The engaging protrusion 205 is constituted by the protrusion upper surface plate 203b and the protrusion inclined wall 203d. In addition, the engaging recess 204 is a recess plate bottom plate 202a formed on the bottom surface of the vehicle mounting mechanism 202 and a seating plate 202b and a transfer plate which are seated on the fixed plate 203c. It is comprised by the recessed part inclination wall 202c which spans 202a) and 202b.

In addition, a pair of long holes 208 are formed in the left and right portions of the recess base plate 202a, and the plate-shaped first support 209 supporting the steel plate 207 above the engaging recess 204. ), A support hole 210 is formed in the first support 209, and the steel sheet 207 is installed through the long hole 208 and the support hole 210.

That is, the magnetic body 206 is inserted in the center of the pair of steel sheets 207, the cut portion 207a is formed on both sides of the upper portion of the steel sheet by the cut portion 207a to the upper end sides of the steel sheet 207 The engagement piece 207b which engages with the support body 209 of this is formed. The work prevention paper 210 is formed in a + shape by the long hole 210A and the small hole 210B formed on both sides at the center thereof, and the full length A of the long hole 210A is the width of the steel plate 207. In addition, the right and left width B of the long hole is at least larger than the thickness of the two plates of the steel plate 207, and the small hole 210B of the support hole 210 has a full length C of the cut portion 207a of the steel plate 207. It is the same dimension as the width.

In the steel plate 207, the engaging piece 207b is engaged with the cavity wall 210a of the small hole 210B of the support 209. The first support 209 is supported by the second support 211 formed on the side of the engaging recess 204. Next, when the operation is described, the engagement projections 205 formed on the mounting plate 203 are engaged to fit the engagement recesses 204 formed on the vehicle-mounted mechanism 202. At this time, the first protrusion piece 207a formed on the steel plate 207 is pressed against the protruding face plate 203b.

This is because the magnetic force of the magnetic body 206 adsorbs the protruding portion face plate 203b made of metal through the steel sheet 207.

However, since the suction force by the magnetic body 206 is weak with respect to the sliding direction (D direction in FIG. 14), when the sliding direction force is applied to the vehicle mounting mechanism 202 (for example, the inertial force when the vehicle is stopped) is applied. At one time, both the inclined walls 202c and 203d of the engaging protrusion 205 and the engaging recess 204 prevent the sliding of the steel plate 207 installed on the vehicle mounting apparatus 202 with respect to the protruding face plate 203b. ) Is meshed and prevented. Thereby, the adsorption holding force with respect to the vibration of the upper and lower sides and itself can be increased.

In addition, the shape of the unevenness serves as a guide for position finishing when the vehicle mounting mechanism 202 is placed on the mounting plate 203 in the upward direction. When the on-vehicle mechanism 202 is moved, the user may grasp the on-vehicle mechanism 202 and release it from the mounting plate 203 with a force greater than that of the magnetic body 206.

In the assembling process, when the steel plate 207 is engaged with the support hole 210, the plate surface of the pair of steel plates 207 is aligned and penetrated through the long hole 210A of the support hole 210, and then between the steel plate 207. A cutout portion 207a formed in each steel plate 207 is inserted into the small hole portion 210B, and the engaging plate 207b is engaged with the hole wall 210a of the small hole portion 210B. The steel plate 207 is attracted to the magnetic body 206 by sandwiching 206.

The lower end of the steel plate 207 supported by the support 209 protrudes outward from the long hole 208 of the engagement recess 204, and then the first support 209 and the second support 211 are fixed. In the present embodiment, the engaging portions are arranged on the vehicle mounting mechanism and the engaging projections are arranged on the mounting plate side. On the contrary, the engaging projections may be arranged on the mounting plate side on the mounting plate side. Furthermore, the position of the tip of the steel sheet is a position indented by the number h from the most protruding outer position of the bottom of the vehicle mounting apparatus 202, but the vehicle mounting apparatus 202 is left unattended if it is located at the same surface or in the opposite position. When foreign matter is adsorbed on the steel plate 207 and actually engaged with the mounting plate 203 on the side of the vehicle body, the foreign matter becomes an obstacle and cannot be engaged at a regular position.

As is apparent from the above description, the present invention is provided with a mounting plate for supporting a vehicle mounting mechanism on a part of the vehicle body so that a mating recess is formed on one of the mounting plates of the vehicle mounting mechanism, and the other on the other of the vehicle mounting mechanism and the mounting plate. The engaging projection portion engaging with the engagement recess is formed so as to form a magnetic material at the bottom of the engagement recess, and the engagement projection portion is made of an adsorbent material adsorbed to the magnetic material. It relates to an engagement device. Therefore, according to the present invention, since the vehicle mounting mechanism is installed on the mounting plate by the adsorptive force of the magnetic body, it is easy to disengage when moving is required, and also by the adsorption force of the magnetic body and the engagement of the part to be engaged with the engaging protrusion. There is an excellent effect of being strong against vibration and easy to use the vehicle mounting mechanism. In the power supply connection device of the on-vehicle device described in the above embodiment, a pair of electrode plates 14 are provided.

Although the length of each of this pair of electrode plate 14 may be the same, you may have the following structures.

Moreover, it is set as three electrode plates instead of two electrode plates. In general, the wiring configuration for vehicle-mounted equipment is mainly used two-wire and three-wire type by the capacitance. This wiring configuration is shown in FIGS. 12 and 13. The two-wire system shown in FIG. 12 is composed of a power supply line a 'and an earth line b'.

In addition, the three-wire type shown in FIG. 13 is adopted at a large capacitance, and is composed of a power line c ', an earth line d', and a control line e ', and controls the energization of the power line c' through a relay f '. Configured.

9 and 10 show the relationship between each electrode terminal and each power insertion portion of an electric appliance having a three-wire wiring configuration. 9 shows the length of the electrode terminal 322 of the control circuit located at the center of each of the electrode terminals 321, 322, and 323 provided at the lower portion of the electric appliance 301, respectively. Each electrode insertion portion 331, 332, formed on the base 302 corresponding to each of the electrode terminals 321, 322, and 323 while being shorter than the length of the terminals 321 and 323, 333 is formed in the same shape and the same height.

That is, the electrode terminal 322 of the control circuit is shorter in length l ₂ than the electrode terminals 321 and 323 of the power supply circuit. In this case, in the state where the electric appliance 301 is temporarily placed on the base 302, the electrode terminals 321 and 323 of both sides correspond to the electrode insertion parts 331 and 333 of the base 302 corresponding thereto. Are in contact with each other and the center electrode terminal 322 is not connected to the electrode insertion portion 332 corresponding thereto. 10 shows different lengths of the electrode terminals 324, 325, and 326 provided at the lower portion of the electric appliance 301. The electrode terminal 324 of the power supply circuit on the left side is made the longest. The electrode terminal 325 of the center control circuit is formed to be the shortest.

That is, the right electrode terminal 326 is shortened by the length l ₄ with respect to the left electrode terminal 324, and the center electrode terminal 325 is shortened by the length l ₃ with respect to the right electrode terminal 326.

In this case, in the state where the electric device 301 is temporarily placed on the base 302, only the electric terminal 324 on the left side contacts the electrode insertion part 334 on the base 302 corresponding thereto, or on both sides. The electrode terminals 324 and 326 come into contact with the respective electrode inserts 334 and 336 on the base 302 corresponding thereto, and at least the center electrode terminal 325 and the corresponding electrode inserts. The unit 335 is in a disconnected state. Therefore, even in this case, damage to the electrode can be prevented. 11 shows the relationship between the positive electrode mechanisms 327 and 328 of the electric appliance 301 having a two-wire wiring configuration and the positive electrode insertion portions 337 and 338 provided on the base 302. The length of one electrode terminal 328 of the circuit is shorter than the length of the other electrode terminal 327 of the power supply circuit by the length l ₃ .

In this case, in a state where the electric appliance 301 is temporarily placed on the base 302, one electrode terminal 328 and the electrode inserting portion 338 on the base 302 corresponding thereto become non-contact. With the above configuration, even when the electric appliance 301 is temporarily placed on the base 302, no voltage is applied to the electrodes of the power supply circuit, so even if the contact is unstable, no arc is generated and the electrode is damaged. Can be prevented. However, in any of the above-described cases (FIGS. 9 to 11), the electrode terminal formed shortly is a length that is reliably inserted into the electrode insertion section when the electric device 301 is securely engaged and fixed on the base 302. It is natural to work.

Furthermore, in each of the above embodiments (9 to 11), the object is achieved by varying the length of the electrode terminal, but the length of the electrode terminal is the same and the dimensions of the electrode insert are different, or the upper surface of the base 305 is provided. It is also possible to achieve the purpose by forming irregularities in the position of the electrode insertion portion to change the position of the set height.

As described above, according to the power supply structure of the electric appliance according to the present invention, the occurrence of arc due to contact failure in the temporary replacement state in which the electric appliance is not securely engaged on the base and damage of the electrode by this are caused. This can be prevented. In the embodiment of the present invention, the carpot has been described, but the present invention is not limited thereto, and the present invention may be used for other vehicle-mounted equipment.

Moreover, the present invention is not limited to the above embodiments, and many modifications and changes can be made to the above embodiments within the scope of the present invention.
