[0044] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0045] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0046] In the related art, two-wheeled or three-wheeled electric vehicles, motorcycles, and low-end four-wheeled vehicles, which are the main vehicles for short-distance commuting, are not equipped with tilt alarm devices due to their low cost and simple structure. When such vehicles are involved in a traffic accident or emergency, the driver needs to manually press a button to activate the alarm device, which is difficult to ensure that the alarm device is activated in time, so secondary injuries are likely to occur in traffic accidents.

[0047] In order to solve the above technical problems, the embodiments of the present application provide a tilt switch, a tilt alarm device and a vehicle.

[0048] The vehicle provided in the embodiment of the present application may include two-wheeled electric vehicles, two-wheeled motorcycles, three-wheeled electric vehicles, three-wheeled motorcycles with low cost and simple structure, and may also include some low-end four-wheeled vehicles. The vehicle is fixedly provided with a tilt alarm device, specifically, the tilt alarm device may be fixedly provided in a storage box, a metal frame or a battery shell under the seat of a two-wheeled vehicle, or may be fixedly provided in a storage box, a bucket, a metal frame or a battery shell under the seat of a three-wheeled vehicle, or may be fixedly provided in a body of a four-wheeled vehicle, such as a passenger compartment, a cockpit, an engine compartment or a luggage compartment, etc.

[0049] The tilt alarm device has a simple structure and low cost. When a vehicle is involved in a traffic accident or emergency, such as collision, rollover, overturning, high-speed cornering, etc., it can automatically turn on the hazard warning lights and / or sound an alarm to warn other vehicles and pedestrians to avoid them in time, thereby effectively reducing the probability of secondary injuries in traffic accidents.

[0050] The tilt switch and tilt alarm device provided in the embodiments of the present application are described in detail below with reference to the drawings in the specification.

[0051] See also Figure 1 , the tilt alarm device may include a power supply DC, an alarm device 104 and a tilt switch 101. The tilt switch 101 is electrically connected to the power supply DC and the alarm device 104, respectively, and is used to close when the tilt angle of the vehicle exceeds the set angle value, and connect the power supply DC and the alarm device 104 in series to form a closed circuit, thereby sending an alarm signal. Among them, the power supply DC provides electrical energy to the alarm device 104, and the alarm device 104 sends an alarm signal. The power supply DC can directly use the vehicle's on-board power supply, such as a 12V vehicle power supply, or a removable independent power supply that is easy to disassemble can be installed separately. The alarm device 104 warns surrounding vehicles or pedestrians through lights and / or sounds, and can directly use the warning lights and / or horns on the vehicle, or can also install indicator lights and / or buzzers on the vehicle.

[0052] It is understandable that, in order to facilitate the driver to autonomously control the switch of the alarm device 104, the tilt alarm device may further include a control switch 102, which is connected in parallel with the tilt switch 101. During daily driving, if the driver deems it necessary to turn on the alarm device 104 for sound and light warning, the control switch 102 may be used for control. Since the control switch 102 is connected in parallel with the tilt switch 101, it will not affect the automatic control of the alarm device 104 by the tilt switch 101. Among them, the control switch 102 may be a conventional button switch or the like.

[0053] See also Figure 1 In order to drive the alarm device 104 with greater power, the tilt alarm device may further include a drive unit 103, one end of the drive unit 103 is electrically connected to the tilt switch 101 and the control switch 102, and the other end of the drive unit 103 is electrically connected to the alarm device 104. When the tilt switch 101 or the control switch 102 is turned on, the drive unit 103 receives the turn-on voltage and can drive the alarm device 104 to turn on. Designers can flexibly select a suitable drive unit 103 according to the specifications and models of the actual alarm device 104 and the power supply DC, and this application will not elaborate on this.

[0054] like Figure 2 , Figure 3 and Figure 4 As shown, the tilt switch 101 may include a bracket 11 , a pendulum 12 , two conductive members 13 and a conductive rod 14 .

[0055] Among them, the bracket 11 can be a frame structure or a plate-like structure. The bracket 11 serves as a base for mounting the pendulum 12, the conductive member 13 and the conductive rod 14. The bracket 11 is fixedly connected to the vehicle and moves with the vehicle. In order to protect the various components of the tilt switch 101 and avoid damage as much as possible, the tilt switch 101 can also include a protective shell 16. The bracket 11, the pendulum 12, the conductive member 13 and the conductive rod 14 are all arranged in the protective shell 16; the bracket 11 is fixedly connected to the protective shell 16. At this time, by fixing the protective shell 16 to the vehicle, it can be ensured that the bracket 11 is fixedly connected to the vehicle, that is, the bracket 11 can be moved with the vehicle. It can be understood that in order to facilitate the fixed connection between the protective shell 16 and the vehicle, for example, to facilitate the application of glue when bonding and to facilitate the operation when fastening with screws, the bottom surface of the protective shell 16 can be set to a plane.

[0056] The pendulum 12 may be polygonal, circular or elliptical, etc., and is usually made of a material with a large mass, such as cast iron, stone, steel, etc. The pendulum 12 is hinged to the bracket 11, and always maintains a vertical downward state under the action of gravity. Therefore, when the vehicle tilts, the bracket 11 fixedly connected to the vehicle will rotate relative to the pendulum 12.

[0057] Two conductive members 13 are fixedly mounted on the bracket 11, and the two conductive members 13 move together with the bracket 11. The two conductive members 13 are located on the periphery of the pendulum 12, see Figure 1 and Figure 3 The two conductive members 13 are respectively connected to a wire 17 , the conductive member 13 on the left can be electrically connected to the power supply DC through a wire 17 , and the conductive member 13 on the right can be electrically connected to the alarm device 104 through a wire 17 .

[0058] The conductive rod 14 is fixedly connected to the pendulum 12. For example, the pendulum 12 can be hinged to the bracket 11 through a pin shaft, and a mounting hole is provided on the pin shaft. The conductive rod 14 is connected to the pendulum 12 by cooperating with the mounting hole on the pin shaft. The structure of the conductive rod 14 can be various, for example, see Figure 3 The conductive rod 14 can be a straight rod, in which case the two conductive members 13 can be symmetrically arranged about the hinge point of the pendulum 12. To facilitate the manufacture and installation of the conductive rod 14, when the protective shell 16 is placed horizontally, the conductive rod 14 can be arranged parallel to the bottom surface of the protective shell 16.

[0059] The pendulum 12 always keeps a vertical downward state under the action of gravity, and the conductive rod 14 fixed to the pendulum 12 is stationary relative to the pendulum 12. When the vehicle tilts, the bracket 11 fixedly connected to the vehicle and the conductive member 13 thereon will rotate relative to the conductive rod 14.

[0060] It should be noted that see Figures 2 to 4 In order to avoid the motion interference between the pendulum 12 and the conductive member 13 and the conductive rod 14, which may cause the tilt switch 101 to malfunction, when the bracket 11 is a plate-like structure, the pendulum 12 can be set on one side of the bracket 11, and the conductive member 13 and the conductive rod 14 can be set on the other side of the bracket 11.

[0061] When the tilt angle of the bracket 11 exceeds the set angle value, one end of the conductive rod 14 is electrically connected to one conductive member 13, and the other end of the conductive rod 14 is electrically connected to another conductive member 13. Figure 3When the vehicle travels inward along a direction perpendicular to the paper plane, if the vehicle tilts to the right, the conductive member 13 rotates clockwise relative to the conductive rod 14. When the tilt angle of the bracket 11 exceeds the set angle value, the conductive member 13 located on the upper side of the bracket 11 is electrically connected to the right end of the conductive rod 14, and the conductive member 13 located on the lower side is electrically connected to the left end of the conductive rod 14, thereby realizing the conduction of the tilt switch 101. Similarly, if the vehicle tilts to the left, the conductive member 13 rotates counterclockwise relative to the conductive rod 14. When the tilt angle of the bracket 11 exceeds the set angle value, the conductive member 13 located on the upper side of the bracket 11 is electrically connected to the left end of the conductive rod 14, and the conductive member 13 located on the lower side is electrically connected to the right end of the conductive rod 14, thereby realizing the conduction of the tilt switch 101.

[0062] The conductive member 13 may be an arc-shaped plate. In order to smoothly electrically connect the conductive rod 14 to the conductive member 13 when the conductive rod 14 rotates relative to the conductive member 13, the concave surface of the conductive member 13 in the shape of an arc-shaped plate may be set to face the conductive rod 14. It is understandable that by adjusting the arc length of the conductive member 13, the electrical connection between the conductive rod 14 and the conductive member 13 at different tilt angles of the bracket 11 can be controlled. In other words, the arc length of the conductive member 13 can be flexibly set according to actual needs, so that the bracket 11 can achieve electrical connection between the conductive rod 14 and the conductive member 13 at a desired tilt angle.

[0063] Considering that after the tilt alarm device is used for a long time, the conductive member 13 and the conductive rod 14 are worn. When the vehicle tilts, the conductive member 13 and the conductive rod 14 are likely to have poor contact, which may cause the tilt alarm device to not work properly. Figures 5 to 8 The tilt switch 101 of the embodiment of the present application may further be provided with an elastic conductive mechanism 15 at both ends of the conductive rod 14, and the elastic conductive mechanism 15 may be used to keep the conductive member 13 in close contact with the conductive rod 14 when the vehicle tilts.

[0064] like Figure 6 and Figure 8 As shown, the elastic conductive mechanism 15 may include an elastic member 151 and a conductive contact 152; the conductive contact 152 is electrically connected to the conductive rod 14; one end of the elastic member 151 is connected to the end of the conductive rod 14, and the other end is connected to the conductive contact 152. Among them, the conductive contact 152 may be a metal conductive member such as a copper column. The elastic member 151 may be a telescopic structural member such as a metal spring, a rubber spring, an elastic diaphragm, etc. When the elastic member 151 is a metal spring, the elastic member 151 is directly electrically connected to the conductive rod 14, so there is no need to use an additional connecting wire to achieve the electrical connection between the conductive contact 152 and the conductive rod 14; when the elastic member 151 is an insulating structure such as a rubber spring, the elastic member 151 may use a wire to connect the conductive contact 152 and the conductive rod 14 to achieve the electrical connection between the conductive contact 152 and the conductive rod 14. See Figure 5 and Figure 7 When the vehicle tilts, the conductive member 13 rotates with the bracket 11 relative to the conductive rod 14. When the tilt angle of the bracket 11 has not exceeded the set angle value, the elastic member 151 is in an extended state, and the elastic member 151 does not apply an elastic force to the conductive contact 152. When the tilt angle of the bracket 11 exceeds the set angle value, the conductive contact 152 contacts the conductive member 13 and the elastic member 151 is in a compressed state. The elastic member 151 applies an elastic force to the conductive contact 152, pressing the conductive contact 152 toward the conductive member 13, so that the conductive contact 152 can be in close contact with the conductive member 13, effectively improving the working reliability of the tilt alarm device.

[0065] Since the elastic member 151 is in an extended state when the tilt angle of the bracket 11 has not exceeded the set angle value, the conductive contact 152 protrudes outward. If the length of the conductive contact 152 protruding outward is large, when the tilt angle of the bracket 11 reaches the set angle value, the conductive contact 152 may be blocked by the conductive member 13, resulting in excessive wear or even breakage of the conductive contact 152. Therefore, in order to make the conductive contact 152 slide smoothly into the conductive member 13, see Figure 6 In a possible embodiment of the present application, guide portions 130 are provided at both ends of the conductive member 13. The two guide portions 130 extend toward both sides of the conductive member 13, respectively, and can guide the conductive contact 152. The guide portion 130 can be Figure 6 The plate in the figure may also be a triangular block, a square block or other block with an inclined surface. The designer may flexibly design the inclination direction and angle of the guide portion 130 according to the specific structure of the conductive contact 152, the protruding length of the conductive contact 152 when the elastic member 151 is in the extended state, etc., and the embodiment of the present application does not specifically limit this.

[0066] In another possible embodiment of the present application, the thickness of the structure of the conductive member 13 can also be designed, and the thickness at both ends of the conductive member 13 is set to be thinner than the thickness in the middle, so that the conductive contact 152 can slide smoothly into the conductive member 13. Figure 7 and Figure 8, the conductive member 13 may include a main body 131 and a thinning portion 132 connected to both ends of the main body 131; the first distance L1 between the side of the thinning portion 132 close to the conductive rod 14 and the hinge point between the conductive rod 14 and the bracket 11 is greater than the second distance L2 between the side of the main body close to the conductive rod 14 and the hinge point between the conductive rod 14 and the bracket 11. In this way, although the conductive contact 152 protrudes outward when the elastic member 151 is in the extended state, the thinning portion 132 can make up for the protruding length of the conductive contact 152, so that the conductive contact 152 and the conductive member 13 can be prevented from being blocked. It can be understood that the thickness of the thinning portion 132 can gradually increase as the distance from the main body 131 decreases, so that the side of the conductive member 13 close to the conductive rod 14 can be smoothed, avoiding the appearance of protruding structures such as steps and ridges to aggravate the wear and loss of the conductive contact 152. In order to make the conductive contact 152 slide into the conductive member 13 more smoothly, a transition fillet may be processed at the end of the thinned portion 132 , and the diameter of the transition fillet may be flexibly selected according to actual conditions.

[0067] In addition, in the embodiment of the present application, a conductive roller can be provided at each end of the conductive rod 14. When the tilt angle of the bracket 11 exceeds the set angle value, the conductive roller can roll and contact with the conductive member 13, thereby reducing friction. After the tilt switch 101 is used for a long time, if the conductive roller fails due to friction loss with the conductive member 13 and cannot be reliably contacted, it only needs to replace the worn conductive roller, which is more convenient for maintenance.

[0068] The solution provided by the embodiment of the present application utilizes the pendulum 12 to be in a vertical downward state under the action of gravity, maintains the posture of the conductive rod 14 fixed on the pendulum 12 constant, and makes the bracket 11 and the conductive member 13 thereon move relative to the conductive rod 14 together with the vehicle. When the vehicle encounters a traffic accident or emergency, such as collision, rollover, overturning, high-speed cornering, etc., the bracket 11 and the conductive member 13 thereon can be tilted relative to the conductive rod 14, and then when the tilt angle of the bracket 11 and the conductive member 13 exceeds the set angle value, the tilt switch 101 is automatically turned on, and the alarm device 104 is turned on in time to remind other vehicles and pedestrians to avoid. The solution of the present application avoids the use of precision sensor devices such as Hall sensors, and can realize the warning of the vehicle when a traffic accident or emergency occurs through a simple mechanical and circuit structure. It is low in cost, and therefore, it can be widely used in two-wheeled or three-wheeled electric vehicles, motorcycles, and low-end four-wheeled vehicles, etc., and can effectively reduce the probability of secondary injuries in traffic accidents.
