[0026] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0027] First of all, it should be noted that some directional words involved in the following description to clearly illustrate the technical solution of the utility model are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.
[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] The utility model provides a vehicle horn switch, see Figures 1 to 5 As shown, it includes: an electrode sheet 3 connected to the first terminal 1, an electrode 4 connected to the second terminal 2, and a magnetic member 5. When the electrode sheet 3 is in a first state, the electrode sheet 3 and the electrode 4 abut against each other, so that the first terminal 1 and the second terminal 2 are in a conductive state. When the electrode sheet 3 is in a second state, the magnetic member 5 adsorbs the electrode sheet 3, so that the first terminal 1 and the second terminal 2 are in a disconnected state.
[0031] It should be noted that the vehicle horn switch of the utility model is mainly used for short-term connection and long-term disconnection of the circuit, so as to realize the control of electrical appliances, equipment or electrical equipment such as horns and lamps. The circuit state needs to be controlled by manually operating the switch. The vehicle horn switch of the utility model includes: a first terminal 1 and a second terminal 2 installed on one side of the base 1, the first terminal 1 and the second terminal 2 are used to be connected to the circuit loop of the car horn, and the short-term connection characteristics of the first terminal 1 and the second terminal 2 are used to control the horn duration of the new energy vehicle horn. The first terminal 1 is electrically connected to the electrode sheet 3, and the second terminal 2 is electrically connected to the electrode 4. The electrode sheet 3 can move up and down, and the position of the electrode 4 is relatively fixed. The magnetic member 5 maintains a certain distance from the electrode 4. The distance requirement does not affect the electrode sheet 3 moving down and contacting the electrode 4 and being sucked away from the electrode 4 by the magnetic member 5. The electrode sheet 3 includes two working states. When the electrode sheet 3 is in the first state, it is in the on state. At this time, the electrode sheet 3 is bent, the bottom of the electrode sheet 3 and the top of the electrode 4 are against each other, the first terminal 1 and the second terminal 2 are connected instantly, and the speaker makes a corresponding sound to remind the person or car in front to avoid or serve as a warning. When the electrode sheet 3 is in the second state, it is in the off state. At this time, the electrode sheet 3 is adsorbed by the magnetic part 5, and the bending amplitude becomes larger. The electrode sheet 3 bends toward the magnetic part 5, so that the bottom of the electrode sheet 3 is separated from the electrode 4, the first terminal 1 and the second terminal 2 are disconnected, and the speaker is in a silent state. The above-mentioned speaker switch can meet the requirements of instant connection, and the car horn honks accordingly, filling the gap in the switch field, avoiding unnecessary conflicts caused by long-term honking, and thus providing more protection for people's life and property safety. At the same time, it provides people with more choices when using switches and facilitates people's lives.
[0032] In some embodiments, the electrode 4 includes an arc portion 41 . When the electrode sheet 3 is in the first state, the arc portion 31 at the end of the electrode sheet 3 and the top arc segment of the arc portion 41 abut against each other, so that the first terminal 1 and the second terminal 2 are conductive. It should be noted that the electrode 4 can be an arc block installed on the base 6, which is made of a conductive material and has a height less than the height of the magnetic member 5. The arc block has an arc portion 41, and an arc portion 31 is formed below the electrode sheet 3. The middle position of the arc portion 31 and the middle position of the arc portion 41 are arranged correspondingly. The electrode sheet 3 is in an initial position and is in a suspended state. When the electrode sheet 3 moves downward to the extreme position, the arc portion 31 and the arc portion 41 are in a non-contact state. Under the adsorption action of the magnetic member 5, the arc portion 31 of the electrode sheet 3 is moved toward the direction of the magnetic member 5. When passing through the top of the arc portion 41, the top arc segments of the arc portion 31 and the arc portion 41 abut against each other, and the first terminal 1 and the second terminal 2 are connected, resulting in a momentary connection, and the car horn honks accordingly.
[0033] In some embodiments, the electrode sheet 3 is an elastic metal part. When the electrode sheet 3 is in the first state or the second state, under the magnetic force of the magnetic part 5, the electrode sheet 3 bends in the direction of the magnetic part 5. It should be noted that the electrode sheet 3 is in the shape of a thin strip, and is made of a metal conductor material that can attract the magnetic part 5. The thin sheet has a flexible characteristic, can be deformed and bent when subjected to external force, and can automatically restore after the external force is removed. When the electrode sheet 3 moves downward to the extreme position, since the arc portion 31 of the electrode sheet 3 is within the range of magnetic adsorption of the magnetic part 5 at this time, under the action of the magnetic force, the electrode sheet 3 bends in the direction of the magnetic part 5, and passes through the first state and the second state in sequence.
[0034] In some embodiments, it also includes: a sleeve 7 mounted on the base 6, the sleeve 7 has a sliding channel, an elastic member 8 is installed in the sliding channel, one end of the elastic member 8 abuts against the bottom of the sliding channel, and the other end abuts against the button switch 9, and the electrode sheet 3 is installed at the bottom of the button switch 9. It should be noted that the sleeve 7 can be mounted on the base 6 by a fastener, and its function is to serve as a receiving chamber for installing the elastic member 8 and the button switch 9, and the cross section is square. The elastic member 8 can be a spring, and the bottom of the button switch 9 abuts against the elastic member 8. As the button switch 9 is pressed down and raised to reset, the elastic member 8 has a compressed state or a reset state. The elastic member 8 is in the reset state, that is, in the initial state, the distance between the arc portion 31 and the arc portion 41 is equal to the stroke spacing of the button switch 9 when it is pressed down and raised to reset. When the horn switch is in the initial state, the button switch 9 is in the reset state, the electrode sheet 3 is suspended at the bottom of the button switch 9, and the electrode sheet 3 and the electrode 4 are in a non-contact state, that is, the first terminal 1 and the second terminal 2 are in a disconnected state. It should be emphasized that an outer cover 12 is also installed on the base 6, and a through hole 13 is opened on the outer cover 12. The button switch 9 passes through the through hole 13 and extends to the outside of the outer cover 12. As the button switch 9 is pressed, the length of the part of the button switch 9 extending out of the outer cover 12 becomes smaller accordingly.
[0035] In some embodiments, the button switch 9 is slidably connected to the sliding channel and can extend outside the sliding channel. The button switch 9 includes a sliding portion 91, and a lifting ear 10 for mounting the electrode sheet 3 is provided at the bottom of the sliding portion 91. It should be noted that the lifting ear 10 is installed on the sliding portion 91. The lifting ear 10 is used to mount the electrode sheet 3 on the one hand, and also has a limiting function on the other hand. The limiting function means that when the button switch 9 rebounds upward, the upper surface of the lifting ear 10 will be pushed against the inner surface of the corresponding position of the outer cover 12, so that the lifting ear 10 can be prevented from being separated from the outer cover 12 and losing control when rebounding upward.
[0036] In some embodiments, the button switch 9 can slide between the first limit position and the second limit position; when the button switch 9 is in the first limit position, the distance between the ear 10 and the electrode 4 is the first distance; when the button switch 9 is in the second limit position, the distance between the ear 10 and the electrode 4 is the second distance; the first distance is greater than the second distance. It should be noted that when the button switch 9 is in the first limit position, at this time, since the button switch 9 is not pressed, the elastic member 8 is in a reset state, that is, the initial state, and the corresponding button switch 9 is in a state of rising and resetting, and the first distance between the ear 10 and the electrode 4 is relatively far; when the button switch 9 is in the second limit position, at this time, since the button switch 9 is pressed down to the limit position, the elastic member 8 is in a compressed state, and the second distance between the ear 10 and the electrode 4 is relatively close. The arc portion 31 of the electrode sheet 3 is within the range of magnetic adsorption of the magnetic member 5. Under the action of the magnetic force, the electrode sheet 3 bends toward the magnetic member 5, and passes through the first state and the second state in sequence, that is, the first state and the second state of the electrode sheet 3 are the states formed after the button switch 9 is in the second limit position. It should be emphasized that when the push button switch 9 is in the first extreme position, the electrode sheet 3 is in a vertical drooping state and does not bend.
[0037] In some embodiments, a baffle 11 is installed on the top of the magnetic member 5, and a protrusion 111 is formed on the baffle 11 toward the electrode 4. When the electrode sheet 3 is in the second state, the protrusion 111 can prevent the arc portion 31 of the electrode sheet 3 from being adsorbed on the surface of the magnetic member 5. It should be noted that a baffle 11 is installed on the top of the magnetic member 5, and a protrusion 111 is formed on the side of the baffle 11 facing the electrode sheet 3. The purpose is that when the magnetic member 5 adsorbs the electrode sheet 3, the protrusion 111 can prevent the electrode sheet 3 from continuing to move toward the magnetic member 5, and prevent the electrode sheet 3 from being adsorbed and attached to the surface of the magnetic member 5, thereby achieving the purpose of only connecting the first terminal 1 and the second terminal 2 once if the button switch 9 is pressed and not released.
[0038] As a relatively preferred embodiment of the vehicle horn switch of the utility model, it includes: an electrode sheet 3 connected to the first terminal 1, an electrode 4 connected to the second terminal 2, and a magnetic member 5. When the electrode sheet 3 is in the first state, the electrode sheet 3 and the electrode 4 abut against each other, so that the first terminal 1 and the second terminal 2 are in a conducting state. When the electrode sheet 3 is in the second state, the magnetic member 5 adsorbs the electrode sheet 3, so that the first terminal 1 and the second terminal 2 are in a disconnected state. The electrode 4 includes an arc portion 41. When the electrode sheet 3 is in the first state, the arc portion 31 at the end of the electrode sheet 3 and the top arc segment of the arc portion 41 abut against each other, so that the first terminal 1 and the second terminal 2 are conducting. The electrode sheet 3 is an elastic metal member. When the electrode sheet 3 is in the first state or the second state, under the magnetic force of the magnetic member 5, the electrode sheet 3 bends toward the direction where the magnetic member 5 is located. It also includes: a sleeve 7 mounted on the base 6, the cross section of the sleeve 7 is square, the sleeve 7 has a sliding channel, an elastic member 8 is installed in the sliding channel, one end of the elastic member 8 abuts against the bottom of the sliding channel, and the other end abuts against the button switch 9, and the electrode sheet 3 is installed at the bottom of the button switch 9. The button switch 9 is slidably connected to the sliding channel and can extend to the outside of the sliding channel. The button switch 9 includes a sliding portion 91, and the sliding portion 91 is provided with a lug 10 for mounting the electrode sheet 3. An outer cover 12 is installed on the base 6, and a through hole 13 is opened on the outer cover 12 for the button switch 9 to pass through. A baffle 11 is installed on the magnetic member 5, and the baffle 11 is formed with a protrusion 111 in the direction of the electrode 4. When the electrode sheet 3 is in the second state, the protrusion 111 can prevent the electrode sheet 3 from being adsorbed on the surface of the magnetic member 5. The button switch 9 can slide between a first limit position and a second limit position; when the button switch 9 is in the first limit position, the distance between the ear 10 and the electrode 4 is a first distance; when the button switch 9 is in the second limit position, the distance between the ear 10 and the electrode 4 is a second distance; the first distance is greater than the second distance. At the first limit position, the button switch 9 is in a reset state, i.e., an initial state. The first state and the second state of the electrode sheet 3 are states formed after the button switch 9 is in the second limit position. The electrode sheet 3 is constructed as a strip structure. When the button switch 9 is in the first limit position, the electrode sheet 3 is in a vertical drooping state.
[0039] The working principle is as follows: when the horn switch is in the initial state, the button switch 9 is in the pop-up state, which is the first extreme position, and the electrode sheet 3 is suspended above the electrode 4. The electrode sheet 3 and the electrode 4 are in a non-contact state. At this time, the first terminal 1 and the second terminal 2 are in a disconnected state. When the button switch 9 is pressed to the first extreme position, the electrode sheet 3 is attracted toward the direction of the magnetic member 5 under the magnetic force of the magnetic member 5, and the electrode sheet 3 is bent. When passing through the top of the arc portion 41, the arc portion 31 and the top arc segment of the arc portion 41 are in contact with each other, which is the first state. The first terminal 1 and the second terminal 2 are connected, resulting in a momentary connection, and the car horn honks accordingly. Since the electrode sheet 3 is still attracted by the magnetic member 5, the electrode sheet 3 is still moving toward the magnetic member 5 until the electrode sheet 3 and the electrode 4 fall off and contact the protrusion 111 of the baffle 11. Because it is blocked by the baffle 11, although the magnetic member 5 is still attracting the electrode sheet 3, it cannot be adsorbed on its surface by the magnetic member 5. If the button switch 9 is pressed and not released, the first terminal 1 and the second terminal 2 are only connected once. When the button switch 9 is released, the button switch 9 rebounds and resets, the electrode sheet 3 falls off the suction range of the magnetic member 5, and the electrode sheet 3 returns to the initial state, so that a single cycle of instant connection can be achieved.
[0040] In addition, the utility model also provides a vehicle, including the vehicle horn switch of the above technical solution, which can meet the conditions that the switch is only turned on for a moment after being pressed, and the car horn only honks once, filling the gap in the switch field, avoiding unnecessary conflicts caused by pressing the horn for a long time, and thus providing more protection for people's life and property safety. At the same time, it provides people with more choices when using switches, making people's lives more convenient.
