Description

Technical Field

[0001] The present invention belongs to the field of signal transmission devices, and in particular relates to a one-button dual-signal sending device, which can be applicable to new energy vehicle charging equipment. Background Art

[0002] With the development of new energy vehicle charging equipment, people have higher and higher requirements for the humanized design of charging guns. In the existing technology, a button of a general charging gun can only send one signal. To achieve two signals, two different buttons need to be triggered. In the control of the charging gun, many control purposes require two signals to work together one after the other to achieve, and in many cases these two signals need to be sent by different devices respectively. Therefore, it is often necessary to use the button of the charging gun to trigger the signals of the two devices one after another to complete the desired action. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a one-key dual-signal sending device.

[0004] The present invention is achieved through the following technical solutions:

[0005] A one-touch dual-signal sending device includes a pressure bar 4, under which a first switch 2 and a second switch 3 are provided. When the pressure bar 4 is pressed down, the second switch 3 is first triggered to change its opening and closing state, thereby sending out a first electrical signal. When the pressure bar 4 is pressed down further, the first switch 2 is triggered to change its opening and closing state, thereby sending out a second electrical signal.

[0006] Preferably, the first switch 2 is a normally open switch, and the second switch 3 is a normally closed switch. When the pressure bar 4 is pressed down, the second switch 3 is first triggered to open its normally closed state, thereby sending out a first electrical signal. The pressure bar 4 continues to be pressed down, triggering the first switch 2 to close its normally open state, thereby sending out a second electrical signal.

[0007] More preferably, the specific structure in which the first switch 2 and the second switch 3 are triggered one by one by the pressure strip is: the first switch 2 and the second switch 3 are both arranged on a base, the pressure strip 4 is arranged above the base 1, and the pressure strip 4 is composed of a fixed area 8, a working area and a pressing area 6 from front to back, the pressure strip 4 is rotatably connected to a fixed fulcrum 11 fixed at a position relative to the base 1 in the fixed area 8, and a torsion spring or a spring is arranged to ensure that the front end of the pressure strip 4 is always in a state of being pressed down without the action of external force, the working area of ​​the pressure strip 4 is arranged above the first switch 2 and ensures that a certain gap is left between the pressure strip 4 and the first switch 2 when the pressing area 6 is not pressed down, that is, to ensure The first switch 2 is always in a normally open state before being pressed, and a support rod 9 is provided on the pressure strip 4, between the pressing area 6 and the working area corresponding to the position of the first switch 2, on a side close to the second switch 3. A side pressure strip 5 is also provided on the base 1 through a side support 7. The middle part of the side pressure strip 5 is connected to the side support 7, the rear end of the side pressure strip 5 is placed on the support rod 9, and the front end is pressed on the second switch 3. Under the action of the support rod 9 of the pressure strip 4 lifting the rear end of the side pressure strip 5, the front end of the side pressure strip 5 is always pressed down and pressed against the second switch 3 in the absence of external force, that is, it is ensured that the second switch 3 is always in a normally closed state before being pressed.

[0008] Furthermore, the pressure strip 4 is in contact with the first switch 2 via a first contact 4 . 1 disposed on the pressure strip, and the side pressure strip 5 is in contact with the second switch 3 via a second contact 3 . 1 disposed on the second switch 3 .

[0009] Furthermore, the support rod 9 is slope-shaped.

[0010] Furthermore, the rear end of the side pressure strip 5 is cylindrical.

[0011] Furthermore, the pressing area 6 is connected to a control button.

[0012] Working principle: because the position of the support rod on the pressure strip overlapped by the rear end of the side pressure strip is closer to the pressing area than the trigger point of the first switch, when the pressing area is pressed, the second switch controlled by the side pressure strip, that is, the normally closed switch, will be triggered faster than the first switch controlled by the pressure strip, that is, the normally open switch. Therefore, at the beginning, when the control button is pressed partially, the side pressure strip is first lifted up and leaves the second switch. At this time, the normally closed second switch is disconnected, and the first electrical signal is generated instantly to complete an instruction. Then, continue to press the remaining control button stroke, so that the first contact on the pressure strip is pressed down to trigger the normally open first switch to be turned on, thereby generating a second electrical signal. That is, using one control button, the opening and closing conditions of the two switches can be changed in turn through different pressing strokes of the button to generate two electrical signals, thereby realizing the function of sending two signals with one control button.

[0013] The present invention also discloses a charging gun for a car charging pile using the one-touch dual-signal sending device. Preferably, the one-touch dual-signal sending device is fixedly arranged in a charging gun housing, a hook (4.2) is provided at the front end of the pressure strip for interlocking with the car socket slot, and a locking tongue is provided on the upper side of the hook (4.2) on the car socket.

[0014] The beneficial effects of the present invention are:

[0015] The structure of the present invention is ingenious and concise, and the gradual and accurate sending of two signals is realized through a control button, which makes it possible to simplify the control equipment. It has a high degree of humanization, strong practicality, and a wide range of applications. It is especially suitable for new energy vehicle charging gun applications and is worthy of promotion.

[0024] like Figure 1-4 As shown, the one-touch dual-signal sending device includes a pressure bar 4, and a first switch 2 and a second switch 3 are provided below the pressure bar 4. When the pressure bar 4 is pressed down, the second switch 3 is first triggered to change its opening and closing state, thereby sending out a first electrical signal. When the pressure bar 4 is pressed down again, the first switch 2 is triggered to change its opening and closing state, thereby sending out a second electrical signal.

[0025] The first switch 2 is a normally open switch, and the second switch 3 is a normally closed switch. When the pressure bar 4 is pressed down, the second switch 3 is first triggered to open its normally closed state, thereby sending out a first electrical signal. The pressure bar 4 continues to be pressed down, triggering the first switch 2 to close its normally open state, thereby sending out a second electrical signal.

[0026] The specific structure of the first switch 2 and the second switch 3 being triggered one by one by the pressure strip is as follows: the first switch 2 and the second switch 3 are both arranged on a base, the pressure strip 4 is arranged above the base 1, and the pressure strip 4 is composed of a fixed area 8, a working area and a pressing area 6 from front to back, the pressure strip 4 is rotatably connected to a fixed fulcrum 11 fixed relative to the base 1 in the fixed area 8, and a torsion spring or a spring is arranged to make the front end of the pressure strip 4 always in a state of being pressed down without the action of external force, the working area of ​​the pressure strip 4 is arranged above the first switch 2 and ensures that a certain gap is left between the pressure strip 4 and the first switch 2 when the pressing area 6 is not pressed down, that is, to ensure that the first The switch 2 is always in a normally open state before being pressed, and a support rod 9 is provided on the pressure strip 4, between the pressing area 6 and the working area corresponding to the position of the first switch 2, on a side close to the second switch 3. The base 1 is also provided with a side pressure strip 5 through a side support 7. The middle part of the side pressure strip 5 is connected to the side support 7, the rear end of the side pressure strip 5 is placed on the support rod 9, and the front end is pressed on the second switch 3. Under the action of the support rod 9 of the pressure strip 4 that keeps lifting the rear end of the side pressure strip 5, the front end of the side pressure strip 5 is always in a state of being pressed down and pressed against the second switch 3 in the absence of external force, that is, it is ensured that the second switch 3 is always in a normally closed state before being pressed.

[0027] The pressure strip 4 is in contact with the first switch 2 via a first contact 4 . 1 arranged on the pressure strip, and the side pressure strip 5 is in contact with the second switch 3 via a second contact 3 . 1 arranged on the second switch 3 .

[0028] The support rod 9 is slope-shaped.

[0029] The rear end of the side pressure strip 5 is cylindrical.

[0030] The pressing area 6 is connected to a control button.

[0031] Working principle: because the position of the support rod on the pressure strip overlapped by the rear end of the side pressure strip is closer to the pressing area than the trigger point of the first switch, when the pressing area is pressed, the second switch controlled by the side pressure strip, that is, the normally closed switch, will be triggered faster than the first switch controlled by the pressure strip, that is, the normally open switch. Therefore, at the beginning, when the control button is pressed partially, the side pressure strip is first lifted up and leaves the second switch. At this time, the normally closed second switch is disconnected, and the first electrical signal is generated instantly to complete an instruction. Then, continue to press the remaining control button stroke to press the first contact on the pressure strip downward to trigger the normally open first switch to be turned on, thereby generating a second electrical signal. That is, using one control button, the opening and closing conditions of the two switches can be changed in turn through different pressing strokes of the button to generate two electrical signals. Each signal can be set with different meanings through the program, thereby realizing the function of sending two signals with one control button.

[0032] Example 1

[0033] like Figure 5-6 As shown, a charging gun is used on a car charging pile using the one-button dual-signal sending device, the base 1 and the fixed fulcrum 11 are fixedly arranged in a charging gun housing, a hook 4.2 is provided at the front end of the pressure strip for interlocking with the car socket slot, and a locking tongue is provided on the upper side of the hook 4.2 on the car socket, wherein the pressure strip 4 is pin-connected to the fixed fulcrum 11 in the fixed area 8, and a torsion spring is provided at the pin connection so that the front end of the pressure strip 4 is always in a downwardly pressed state without the action of external force.

[0034] Example 2

[0035] like Figure 7 As shown, a charging gun is used on a car charging pile using the one-button dual-signal sending device, the base 1 and the fixed fulcrum 11 are fixedly arranged in a charging gun housing, a hook 4.2 is provided at the front end of the pressure strip for interlocking with the car socket slot, and a locking tongue is provided on the upper side of the hook 4.2 on the car socket, wherein the pressure strip 4 is pin-connected with the fixed fulcrum 11 in the fixed area 8, and a protrusion is provided on the fixed area 8 at the front end of the pin connection, and then a spring 10 is sleeved on the protrusion to allow the spring to contact the gun housing where the fixed fulcrum 11 is located, so that the front end of the pressure strip 4 is always in a downwardly pressed state without the action of external force.

[0036] Application scenario demonstration: At the beginning, when the control button is pressed partially, the side pressure strip will first lift up to make it leave the normally closed second switch. At this time, the second switch is disconnected, and the first signal will be generated. This signal can be to let the charging pile send a signal to the car to let the car withdraw the lock tongue. Then, continue to press the remaining control button stroke, and the normally open first switch is triggered to turn on, thereby generating a second signal. This signal can be to cut off the power of the charging gun of the electric pile. At this time, the charging gun can be safely pulled out, that is, by pressing a button set on the charging gun, the charging gun can be safely and quickly pulled out. Compared with the previous action of first pressing the car key or the car control APP or the charging pile to control the car to withdraw the lock tongue between the charging gun and the car, and then pulling the charging gun from the car is more concise, simple, humane, and saves steps.

[0037] The structure of the present invention is ingenious and concise, and the gradual and accurate sending of two signals is realized through a control button, which makes it possible to simplify the control equipment. It has a high degree of humanization, strong practicality, and a wide range of applications. It is especially suitable for new energy vehicle charging gun applications and is worthy of promotion.
