[0028] The automobile brake light switch is an important component for transmitting the driver's brake signal. The traditional brake light switch is a contact structure and has various abnormal noises, such as abnormal switch noise when the pedal is pressed down and abnormal switch noise when the pedal rebounds. However, current vehicles have higher requirements for NVH performance. In order to solve the problem of abnormal switch noise, non-contact switches have been derived.

[0029] At present, when the brake pedal is released, the induction bracket of the non-contact switch is prone to rebound and repeatedly hit the switch due to inertia, causing the switch to loosen or shift, which in turn leads to induction failure, the brake light is always on, and the vehicle continues to brake. Please refer to Figure 1 , Figure 1 is a schematic diagram of the structure of a vehicle according to one or more embodiments of the present application.

[0030] The vehicle 1 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended range vehicle, etc. The vehicle 1 may be a front-wheel drive vehicle, a four-wheel drive vehicle, etc. The vehicle 1 includes a brake light switch assembly 2, which is connected to a brake pedal and can be used to control the turning on and off of the brake light.

[0031] Please refer to Figure 2 , Figure 2 is a schematic structural diagram of a brake light switch assembly according to one or more embodiments of the present application.

[0032] In order to solve the above problems, the present application provides a brake light switch assembly 2, which includes: a switch body 10, a mounting platform 20, a sensing bracket 30 and a limiting portion 40. The switch body 10 includes a sensing portion 11; the mounting platform 20 includes a mounting portion 21, the mounting portion 21 has a first surface 211 and a second surface 212 opposite to each other, and the mounting portion 21 is provided with a first mounting hole 213 connecting the first surface 211 and the second surface 212, and the switch body 10 is inserted into the first mounting hole 213 so that the sensing portion 11 protrudes from the second surface 212 through the first mounting hole 213; the sensing bracket 30 is spaced from the second surface 212 and arranged opposite to the sensing portion 11, and the sensing bracket 30 is connected to the brake pedal; the limiting portion 40 is connected to the mounting platform 20 and protrudes from the second surface 212; wherein the size of the limiting portion 40 protruding from the second surface 212 is larger than the size of the sensing portion 11 protruding from the second surface 212, and the brake pedal can drive the sensing bracket 30 to move in a direction perpendicular to the first surface 211 and the second surface 212.

[0033] The mounting platform 20 can provide support and protection for the switch body 10 and the limit part 40. The induction bracket 30 and the induction part 11 of the switch body 10 can cooperate with each other through induction to control the opening or closing of the brake light. For example, the induction part 11 can be a Hall sensor, and the induction bracket 30 can be provided with an induction magnet. It can be understood that when the induction bracket 30 is close to the induction part 11, the switch body 10 controls the brake light to be turned off, and the vehicle 1 can drive normally. When the induction bracket 30 is away from the induction part 11, the switch body 10 controls the brake light to be turned on, and the vehicle 1 is in a braking state. The induction bracket 30 is connected to the brake pedal. When the brake pedal is stepped on, the induction bracket 30 is away from the induction part 11, and the brake light is turned on. When the brake pedal is released, the induction bracket 30 is close to the induction part 11, and the brake light is turned off. Therefore, in the process of alternately stepping on and releasing the brake pedal, the induction bracket 30 moves back and forth in a direction perpendicular to the first surface 211 and the second surface 212. The switch body 10 is inserted into the first mounting hole 213, and the sensing part 11 protrudes from the second surface 212 through the first mounting hole 213. When the brake pedal is released, the sensing bracket 30 approaches the second surface 212. Under the action of inertia, the sensing bracket 30 has a tendency to continue to approach the second surface 212 or even contact the sensing part 11. The size of the limiting part 40 protruding from the second surface 212 is larger than the size of the sensing part 11 protruding from the second surface 212. When the sensing bracket 30 contacts the limiting part 40, the limiting part 40 can prevent the sensing bracket 30 from continuing to approach the second surface 212, thereby reducing the risk of the sensing bracket 30 colliding with the sensing part 11.

[0034] Through the above-mentioned embodiment, the sensing part 11 can cooperate with the sensing bracket 30 to control the switch of the brake light. When the sensing bracket 30 approaches the sensing part 11 driven by the brake pedal, the limiting part 40 can block the sensing bracket 30. Therefore, the limiting part 40 can alleviate the risk of the sensing bracket 30 colliding with the sensing part 11 under the action of inertia, causing the switch body 10 to withdraw from the first mounting hole 213, thereby reducing the risk of the sensing part 11 and the sensing bracket 30 failing to sense, resulting in the brake light being always on and the vehicle 1 continuously braking, thereby improving the reliability of the brake light switch assembly 2.

[0035] In some embodiments, the sensing bracket 30 can move between a first position and a second position relative to the sensing portion 11; at the first position, the first distance between the sensing bracket 30 and the sensing portion 11 is greater than the sensing distance, and the switch body 10 is in an open state; at the second position, the sensing bracket 30 abuts against the limiting portion 40, so that the sensing bracket 30 is spaced from the sensing portion 11, the second distance between the sensing bracket 30 and the sensing portion 11 is less than the sensing distance, and the switch body 10 is in a closed state. It can be understood that the first position and the second position can be spaced in a direction perpendicular to the first surface 211 and the second surface 212. The sensing distance may refer to the maximum distance at which the sensing portion 11 can sense the sensing bracket 30 and turn off the brake light. When the brake pedal is in a stepped state, the sensing bracket 30 is located at the first position, and the first distance between the sensing portion 11 and the sensing bracket 30 is greater than the sensing distance. When the brake pedal is in a released state, the sensing bracket 30 is located at the second position, and the second distance between the sensing portion 11 and the sensing bracket 30 is greater than the sensing distance. Therefore, it is convenient to control the turning on and off of the brake light by the distance between the sensing part 11 and the sensing bracket 30, and the sensing bracket 30 abuts against the limiting part 40 when it is in the second position closest to the sensing part 11, reducing the risk of the sensing bracket 30 colliding with the sensing part 11.

[0036] In some embodiments, at the second position, the second distance is greater than or equal to 0.5 mm and less than or equal to 1 mm. Thus, when the brake pedal is in a released state, the sensing portion 11 can sense the sensing bracket 30 at the second position, further reducing the risk of the sensing portion 11 being too far away from the sensing bracket 30 when the brake pedal is in a released state, resulting in sensing failure, and the brake light being always on, causing the vehicle 1 to be unable to drive due to continuous braking.

[0037] In some embodiments, the mounting platform 20 is further provided with a second mounting hole 214 connecting the first surface 211 and the second surface 212, the second mounting hole 214 is spaced apart from the first mounting hole 213, and the limiting portion 40 is inserted into the second mounting hole 214 and at least partially protrudes from the second surface 212. The limiting portion 40 is inserted into the second mounting hole 214 so that the limiting portion 40 is connected and fixed to the mounting platform 20. In some application scenarios, the limiting portion 40 may partially protrude from the second surface 212 and may also partially protrude from the first surface 211. It is understandable that the limiting portion 40 inserted into the second mounting hole 214 can facilitate the installation and removal of the limiting portion 40. Thus, the convenience and flexibility of the installation of the limiting portion 40 are improved.

[0038] In some embodiments, the limiting part 40 includes a first fixing member 41 and a buffering part 42. The first fixing member 41 is inserted into the second mounting hole 214, and the buffering part 42 is connected to one end of the first fixing member 41 facing the second surface 212. The first fixing member 41 may include but is not limited to a latch, a stud, a bolt, etc. The buffering part 42 may have a certain elasticity, and the limiting part 40 may block the tendency of the sensing bracket 30 to approach the second surface 212 through the buffering part 42. For example, when the brake pedal changes from the stepped state to the released state, the sensing bracket 30 gradually approaches the second surface 212 of the mounting platform 20. When the sensing bracket 30 abuts against the limiting part 40, the sensing bracket 30 collides with the buffering part 42 and stops approaching the second surface 212. The buffering part 42 can buffer the hard collision between the sensing bracket 30 and the limiting part 40. Therefore, the buffering part 42 can reduce the sound when the sensing bracket 30 collides with the limiting part 40, reduce the noise of the vehicle 1, and at the same time extend the service life of the sensing bracket 30 and the limiting part 40.

[0039] In some embodiments, the first fixing member 41 is provided with a first thread 411, and the inner wall of the second mounting hole 214 is provided with a second thread 215, and the first fixing member 41 is inserted into the second mounting hole 214 through the first thread 411 and the second thread 215. In this embodiment, the first thread 411 is an external thread, the second thread 215 is an internal thread, and the first fixing member 41 and the second mounting hole 214 are connected together through internal and external threads. It is to be noted that the threaded connection between the first fixing member 41 and the second mounting hole 214 is more stable than the clamping and plug-in connection, and is easier to install and adjust the first fixing member 41. Among them, the second thread 215 can be embedded in the second mounting hole 214 through a threaded sleeve, thereby reducing the difficulty of production. It is understandable that in actual production, there is generally a gap tolerance of ±1.2 mm between the sensing bracket 30 and the mounting portion 21, and the first fixing member 41 and the second mounting hole 214 are connected by the first thread 411 and the second thread 215, so as to adjust the fixed position of the first fixing member 41 in the second mounting hole 214, thereby adjusting the size of the limiting portion 40 protruding from the second surface 212, so that the size of the limiting portion 40 protruding from the second surface 212 is greater than the size of the sensing portion 11 protruding from the second surface 212. Therefore, the first thread 411 and the second thread 215 improve the stability of the installation of the limiting portion 40, and at the same time improve the flexibility and adaptability of the limiting portion 40.

[0040] In some embodiments, the limiting portion 40 further includes a second fixing member 43, which is sleeved on an end of the first fixing member 41 away from the buffer portion 42, and the second fixing member 43 abuts against the second surface 212. The second fixing member 43 can fix the first fixing member 41, thereby enhancing the stability of the fastening of the limiting portion 40 and the mounting platform 20. As a result, the second fixing member 43 reduces the risk of the limiting portion 40 failing due to looseness between the first fixing member 41 and the second mounting hole 214 after the sensing bracket 30 repeatedly collides with the limiting portion 40.

[0041] In some embodiments, the inner wall of the second fixing member 43 is provided with a third thread 431, and the second fixing member 43 is sleeved on the first fixing member 41 through the first thread 411 and the third thread 431. The second fixing member 43 may be a nut or the like. In this embodiment, the first thread 411 is an external thread, and the third thread 431 is an internal thread. The first fixing member 41 and the second fixing member 43 are fixedly connected through the first thread 411 and the third thread 431, thereby improving the stabilizing effect of the second fixing member 43 on the first fixing member 41, thereby further reducing the risk of the first fixing member 41 and the second mounting hole 214 being loosened to cause the limiter 40 to fail, thereby improving the reliability of the brake light switch assembly 2.

[0042] In some embodiments, the switch body 10 further includes a main body 12, the main body 12 is inserted into the first mounting hole 213, and the sensing part 11 is connected to an end of the main body 12 away from the first surface 211. The switch body 10 is inserted into the first mounting hole 213 through the main body 12, and the main body 12 can control the opening and closing of the brake light through the distance between the sensing part 11 and the sensing bracket 30. The main body 12 is inserted into the first mounting hole 213, which is convenient for improving the stability of the connection between the switch body 10 and the mounting platform 20, and is convenient for the installation and adjustment of the sensing part 11, so that the sensing part 11 and the sensing bracket 30 cooperate with each other. In this way, the reliability and flexibility of the brake light switch assembly 2 are improved.

[0043] In summary, the present application provides a brake light switch assembly 2, which includes: a switch body 10, a mounting platform 20, a sensing bracket 30 and a limiting portion 40. The switch body 10 includes a sensing portion 11; the mounting platform 20 includes a mounting portion 21, the mounting portion 21 has a first surface 211 and a second surface 212 opposite to each other, the mounting portion 21 is provided with a first mounting hole 213 connecting the first surface 211 and the second surface 212, the switch body 10 is inserted into the first mounting hole 213, so that the sensing portion 11 protrudes from the second surface 212 through the first mounting hole 213; the sensing bracket 30 is spaced from the second surface 212 and arranged opposite to the sensing portion 11, and the sensing bracket 30 is connected to the brake pedal; the limiting portion 40 is connected to the mounting platform 20 and protrudes from the second surface 212; wherein the size of the limiting portion 40 protruding from the second surface 212 is greater than the size of the sensing portion 11 protruding from the second surface 212, and the brake pedal can drive the sensing bracket 30 to move in a direction perpendicular to the first surface 211 and the second surface 212. Through the above-mentioned embodiment, the sensing part 11 can cooperate with the sensing bracket 30 to control the switch of the brake light. When the sensing bracket 30 approaches the sensing part 11 driven by the brake pedal, the limiting part 40 can block the sensing bracket 30. Therefore, the limiting part 40 can alleviate the risk of the sensing bracket 30 colliding with the sensing part 11 under the action of inertia, causing the switch body 10 to withdraw from the first mounting hole 213, thereby reducing the risk of the sensing part 11 and the sensing bracket 30 failing to sense, resulting in the brake light being always on and the vehicle 1 continuously braking, thereby improving the reliability of the brake light switch assembly 2. Compared with other brake light switch assemblies, the brake light switch assembly 2 provided by the present application has better reliability.
