Description

Technical Field

[0001] The utility model relates to the technical field of vehicle braking control, in particular to a brake light switch, a brake pedal and a vehicle. Background Art

[0002] Currently, since the contact block rotates with the pedal arm, its movement is an arc trajectory. From the moment the contact block touches the head of the switch push rod to the moment the switch push rod is completely compressed in place, there is a relative sliding displacement at the contact point between the head of the switch push rod and the contact block throughout the process. In addition to the axial force on the switch push rod of the brake light switch, there is also a lateral frictional force acting on it, which easily causes noise problems. The action of the lateral force also easily causes the push rod to deflect during the actual movement process, resulting in interference, excessive wear and noise problems due to the non-coaxial relative movement with the switch housing. Therefore, the sliding movement at the contact point between the switch push rod and the contact block easily causes noise and excessive wear problems. Summary of the Utility Model

[0026] As Figures 1-4 shown, an embodiment of the present utility model provides a brake light switch 1, which includes a switch body 10, a housing 11 and a moving component 20; the housing 11 is sleeved on the switch body 10; one end of the moving component 20 is movably arranged on the inner wall of one end of the switch body 10, and the other end extends outside the switch body 10; when the moving component 20 is subjected to an external force, it slides along the inner wall of the switch body 10.

[0027] In this embodiment, as Figures 1-4 shown, one end of the moving component 20 is movably connected to the inner wall of the switch body 10, that is, when the moving component 20 is subjected to an external force, the moving component 20 can perform a sliding motion on the inner wall of the switch body 10.

[0028] The brake light switch 1 can be assembled on the brake pedal 2; Figure 2 is a cross-sectional view of the brake light switch 1 not assembled on the brake pedal 2, that is, the state where the brake light switch 1 is not subjected to an external force.

[0029] In one embodiment, as Figures 1-4 shown, the moving component 20 includes a hollow push rod 21, an upper limit block 22, a spring 23, a lower limit block 24 and a ball 25; the hollow push rod 21 is partially arranged inside the switch body 10; the upper limit block 22, the spring 23, the lower limit block 24 and the ball 25 are all arranged inside one end of the hollow push rod 21 far from the switch body 10; the second end of the upper limit block 22 is connected to the first end of the lower limit block 24 through the spring 23; a ball connection groove is arranged at the second end of the lower limit block 24, and the ball 25 is movably connected to the ball connection groove.

[0030] In this embodiment, as Figures 1-4 shown, one end of the hollow push rod 21 is movably connected inside the switch body 10, and the other end extends outside the switch body 10; that is, when an external force is applied, the hollow push rod 21 can slide upward or downward on the inner wall at one end of the switch body 10. In this way, the length of the other end of the hollow push rod 21 extending outside the switch body 10 can be changed according to the magnitude of the external force applied, so as to reduce wear.

[0031] The hollow push rod 21 is a cylindrical hollow rod body with one end open, and the upper limit block 22, the spring 23, the lower limit block 24, and the ball 25 are all arranged inside the end of the hollow push rod 21 far from the switch body 10, that is, the upper limit block 22, the spring 23, the lower limit block 24, and the ball 25 are all arranged inside the other end of the hollow push rod 21 extending outside the switch body 10.

[0032] The upper limit block 22, the spring 23, the lower limit block 24, and the ball 25 are sequentially arranged inside the hollow rod body of the hollow push rod 21 at the end far from the switch body 10 in the order from top to bottom. The upper limit block 22 is connected to the lower limit block 24 through the spring 23, that is, the upper limit block 22 and the lower limit block 24 are not directly connected, but the spring 23 is used as an intermediate component connecting the upper limit block 22 and the lower limit block 24. The second end of the lower limit block 24 is provided with the ball connection groove, that is, the end of the lower limit block 24 far from the spring 23 is provided with the ball connection groove, and the ball connection groove is adaptively connected to the ball 25, that is, the radius of the ball connection groove is greater than or equal to the radius of the ball 25. In this way, the ball 25 can freely roll in the ball connection groove. Among them, the materials of the switch body 10 and the housing 11 can be plastic, specifically polyhexamethylene adipamide, commonly known as nylon-66; the material of the hollow push rod 21 can be metal; the materials of the upper limit block 22 and the lower limit block 24 can be nylon (polyamide fiber, PA) materials; the material of the spring 23 can be a metal material; the material of the ball 25 can be metal.

[0033] The brake light switch 1 can be assembled on the brake pedal 2; Figure 2It is a sectional view of the brake light switch 1 not assembled to the brake pedal 2, that is, a structural diagram of the state where the brake light switch 1 is not subject to external force; at this time, the hollow push rod 21 naturally extends out of the switch body 10 under the action of gravity and is not subject to the applied external force; the lower limit block 24 and the ball 25 are subject to the elastic force of the spring 23 and the acting force of the hollow rod body of the hollow push rod 21.

[0034] In one embodiment, as Figures 1-4 shown, the upper limit block 22 is fixedly arranged inside the hollow push rod 21, and the lower limit block 24 is movably connected inside the hollow push rod 21.

[0035] In this embodiment, as Figures 1-4 shown, the upper limit block 22 is arranged inside the other end of the hollow push rod 21 extending out of the switch body 10 and is fixed to the inner wall of the hollow rod body of the hollow push rod 21; the lower limit block 24 is movably connected to the inner wall of the hollow rod body of the hollow push rod 21, that is, the lower limit block 24 can perform upward or downward sliding movement on the inner wall of the hollow rod body of the hollow push rod 21.

[0036] In one embodiment, as Figures 1-4 shown, a first spring groove is provided at the second end of the upper limit block 22, and the first end of the spring 23 is fixedly connected to the first spring groove; a second spring groove is provided at the first end of the lower limit block 24, and the second end of the spring 23 is fixedly connected to the second spring groove.

[0037] In this embodiment, as Figures 1-4 shown, the first end of the spring 23 is fixedly connected to the first spring groove to perform an embedded fixed connection between the first end of the spring 23 and the first spring groove. The second end of the spring 23 is embedded and connected to the second spring groove; that is, an embedded fixed connection is performed between the second end of the spring 23 and the second spring groove. Therefore, the stability is improved.

[0038] In one embodiment, as Figures 1-4 shown, the depth of the first spring groove is less than the depth of the second spring groove.

[0039] In this embodiment, as Figures 1-4As shown, the depth of the first spring groove is less than that of the second spring groove, that is, the length of the first end of the spring 23 embedded in the first spring groove is less than the length of the second end of the spring 23 embedded in the second spring groove. Since the upper limit block 22 is fixedly arranged on the inner wall of the hollow rod body of the hollow push rod 21 and the lower limit block 24 is movably arranged on the inner wall of the hollow rod body of the hollow push rod 21, the depth of the first spring groove is set to be less than that of the second spring groove to improve the stability of the lower limit block 24 during operation.

[0040] In one embodiment, as Figures 1-4 shown, an arc structure 26 is arranged at one end of the hollow push rod 21 away from the switch body 10, and the arc structure 26 is connected to the ball 25.

[0041] In this embodiment, as Figures 1-4 shown, arc structures 26 bent inward are arranged on both sides of the hollow rod body of the hollow push rod 21 to limit the movement range of the ball 25. The length between the arc structures 26 on both sides of the hollow push rod 21 is less than or equal to the diameter of the ball 25; the ball 25 can perform sliding and / or rolling movements upward or downward and / or leftward or rightward on the inner wall of the hollow rod body of the hollow push rod 21.

[0042] Please refer to Figures 5-8 , an embodiment of the present invention further provides a brake pedal 2, which includes the brake light switch 1 as described in any of the above embodiments, and further includes a fixed bracket 50, a switch contact block 41, a pedal arm 40, a rotating shaft 31 and a support 30; the rotating shaft 31 penetrates through one end of the support 30 and also penetrates through one end of the pedal arm 40; the switch contact block 41 is fixedly arranged at one end of the pedal arm 40 close to the rotating shaft 31; the fixed bracket 50 is arranged at one end of the support 30 away from the rotating shaft 31; one end of the switch body 10 of the brake light switch 1 provided with the moving component 20 penetrates through one end of the fixed bracket 50 away from the support 30, and the moving component 20 is movably connected to the switch contact block 41.

[0043] In this embodiment, as Figures 5-8As shown, the brake light switch 1 is assembled on the brake pedal 2. Specifically, the brake light switch 1 is assembled on one end of the fixed bracket 50 away from the support 30; the brake light switch 1 includes a switch body 10, a housing 11 and a moving component 20; the moving component 20 includes a hollow push rod 21, an upper limit block 22, a spring 23, a lower limit block 24 and a ball 25; both the hollow push rod 21 and the ball 25 are movably connected to the switch contact block 41, that is, the hollow push rod 21 and the ball 25 can perform a rolling motion on the switch contact block 41. The rotating shaft 31 sequentially penetrates through the side plate of the support 30, the pedal arm 40 and the other side plate of the support 30; the pedal arm 40 rotates in an arc trajectory with the rotating shaft 31 as the support center point. A pedal is provided at one end of the pedal arm 40 away from the rotating shaft 31; the pedal is a flat plate for receiving external force, and vertical groove depressions are provided thereon for increasing friction to enhance the stability of the pedal when receiving external force, and this external force can be provided by the stepping force of the foot or other acting forces.

[0044] When the pedal arm 40 receives an external force, it rotates in an arc trajectory with the rotating shaft 31 as the center, and the switch contact block 41 provided on the pedal arm 40 also rotates in an arc trajectory with the rotating shaft 31 as the center; at the same time, with the rotation of the arc trajectory of the switch contact block 41, the hollow push rod 21, the spring 23, the lower limit block 24 and the ball 25 all perform an upward or downward sliding motion, and the ball 25 also performs a left or right rolling motion to reduce wear and noise generation and improve the smoothness of the motion.

[0045] As Figures 3-4 and Figures 7-8 shown, it is a cross-sectional view of the brake light switch 1 assembled on the brake pedal 2, that is, a structural diagram of the state where the brake light switch 1 is subjected to an external force; Figure 3 and Figure 7 is a structural diagram of the initial state when the brake light switch 1 is subjected to the external force of the switch contact block 41. At this time, the switch contact block 41 has not started to rotate in an arc trajectory with the pedal arm 40, that is, the pedal arm 40 is in a static state (i.e., the initial state, the state before starting to move), the switch contact block 41 is in a static state, and the brake light switch 1 is in a compressed state.

[0046] Figure 4 and Figure 8It is a structural diagram of the motion state when the brake lamp switch 1 is subjected to the external force of the switch bumper 41. At this time, the switch bumper 41 starts to rotate along the downward arc trajectory with the pedal arm 40, that is, the pedal arm 40 is in a motion state, the switch bumper 41 is in a motion state, and the brake lamp switch 1 is in a released state. At the same time, a sensor is also provided inside the brake lamp switch 1. When the brake lamp switch 1 is in the released state, this sensor can send a switch signal to the vehicle's main console for brake reminder processing or clutch shifting processing. Figure 4 and Figure 8 It is a structural diagram of the motion state when the brake lamp switch 1 is subjected to the external force of the switch bumper 41. At this time, the switch bumper 41 starts to rotate along the upward arc trajectory with the pedal arm 40, that is, during the process of the pedal arm 40 returning from the motion state to the static state, the switch bumper 41 is in the process of returning from the motion state to the static state, and the brake lamp switch 1 is in the process of returning from the released state to the compressed state.

[0047] It should be noted that for the convenience of understanding, in Figures 7-8 the fixed bracket 50 is not shown. When the brake lamp switch 1 is in the released state or the compressed state, the hollow push rod 21 and the ball 25 are always connected to the switch bumper 41.

[0048] As Figure 3 and Figure 7 shown, when the pedal arm 40 is in the static state, the switch bumper 41 is in the static state, and the brake lamp switch 1 is in the compressed state. Specifically, the switch bumper 41 applies an external force to the hollow push rod 21 and the ball 25. The hollow push rod 21 moves upward along the inner wall of the switch body 10, and the ball 25 moves upward along the inner wall of the hollow rod body of the hollow push rod 21. Moreover, the ball 25 pushes the lower limit block 24 to also move upward along the inner wall of the hollow rod body of the hollow push rod 21, and the lower limit block 24 compresses the spring 23; until the upper limit block 22, the spring 23, the lower limit block 24, and the ball 25 all stop moving. At this time, the spring 23 is in the compressed state and is in the fully compressed state.

[0049] As Figure 4 and Figure 8As shown, when the pedal arm 40 is in a moving state, the switch contact block 41 is in a moving state, and the brake light switch 1 is in a released state. Specifically, when an external force is applied to the pedal arm 40, the pedal arm 40 drives the switch contact block 41 to rotate along a downward arc trajectory. The overall movement of the pedal arm 40 and the switch contact block 41 is downward. Therefore, the switch contact block 41 gradually releases the hollow push rod 21 and the ball 25, and the ball 25 rolls on the switch contact block 41. In this way, the hollow push rod 21 slides downward along the inner wall of the switch body 10, the ball 25 slides downward along the inner wall of the hollow rod body of the hollow push rod 21, and the ball 25 pushes the lower limit block 24 to also slide downward along the inner wall of the hollow rod body of the hollow push rod 21. The lower limit block 24 gradually releases the spring 23, and at this time, the spring 23 is in a released state. At the same time, when the switch contact block 41 rotates along an arc trajectory, a lateral force is also applied to the ball 25, and the ball 25 starts to roll left or right on the switch contact block 41. That is, the lateral force received by the ball 25 generates a rotational torque that causes the ball 25 to rotate. Therefore, no sliding friction is generated between the ball 25 and the switch contact block 41, and the lateral force acting on the hollow push rod 21 is also reduced, avoiding the occurrence of noise and wear, and improving the smoothness of use.

[0050] As Figure 4 and Figure 8As shown, during the process of the pedal arm 40 moving from the moving state back to the stationary state, during the process of the switch contact block 41 moving from the moving state back to the stationary state, and during the process of the brake light switch 1 moving from the released state back to the compressed state. Specifically, when an external force is applied to the pedal arm 40, the pedal arm 40 drives the switch contact block 41 to rotate in an upward arc trajectory. The overall movement of the pedal arm 40 and the switch contact block 41 is upward. Therefore, the switch contact block 41 gradually pushes the hollow push rod 21 and the ball 25 upward, and the ball 25 rolls on the switch contact block 41. In this way, the hollow push rod 21 slides upward along the inner wall of the switch body 10, the ball 25 slides upward along the inner wall of the hollow rod body of the hollow push rod 21, and the ball 25 also pushes the lower limit block 24 to slide upward along the inner wall of the hollow rod body of the hollow push rod 21, and the lower limit block 24 gradually compresses the spring 23. Until the pedal arm 40 and the switch contact block 41 both stop moving, at this time, the spring 23 returns to the compressed state. At the same time, when the switch contact block 41 rotates in an arc trajectory, a lateral force is also applied to the ball 25, and the ball 25 starts to roll left or right on the switch contact block 41. That is, the lateral force received by the ball 25 generates a rotational torque that causes the ball 25 to rotate. Therefore, no sliding friction is generated between the ball 25 and the switch contact block 41, and the lateral force acting on the hollow push rod 21 is also reduced, avoiding the occurrence of noise and wear, and improving the smoothness of use.

[0051] In one embodiment, as Figures 1-3 shown, a first side plate 51 and a second side plate 52 are provided on the fixed bracket 50, and the first side plate 51 and the second side plate 52 are perpendicularly connected; the switch body 10 and the hollow push rod 21 in the motion assembly 20 penetrate through the first side plate 51, and the second side plate 52 is connected to the support 30.

[0052] In this embodiment, as Figures 1-3 shown, one end of the second side plate 52 is fixedly connected to the side plate of the support 30, and the other end of the second side plate 52 away from the side plate of the support 30 is connected to the first side plate 51; the first side plate 51 and the other end of the second side plate 52 away from the side plate of the support 30 are perpendicularly connected, and the first side plate 51 and the second side plate 52 are integrally formed.

[0053] In one embodiment, the switch body 10 is perpendicularly connected to the first side plate 51.

[0054] In this embodiment, one end of the switch body 10 where the moving component 20 is provided penetrates and is vertically fixed to the first side plate 51, that is, the first side plate 51 is provided with a hole and a fixing member adapted to one end of the switch body 10 where the moving component 20 is provided; at the same time, the hollow push rod 21 is also perpendicular to the first side plate 51.

[0055] When an external force is applied to the hollow push rod 21 and the ball 25, the first side plate 51 ensures a stable connection to ensure the stability of the brake light switch 1, thereby improving the use safety.

[0056] Please refer to FIGS. 1-8. An embodiment of the present invention further provides a vehicle, including the brake pedal 2 as described in any one of the above embodiments.

[0057] In this embodiment, as Figures 1-8 shown, the vehicle can be a sedan, a truck, a bus, a trailer, etc., that is, the brake pedal 2 can be arranged in the cockpit of vehicles such as sedans, trucks, buses, and trailers.

[0058] The brake pedal 2 includes the brake light switch 1 as described in any one of the above embodiments, and further includes a fixed bracket 50, a switch bumper 41, a pedal arm 40, a rotating shaft 31, and a support 30; the rotating shaft 31 penetrates one end of the support 30 and also penetrates one end of the pedal arm 40; the switch bumper 41 is fixedly arranged at one end of the pedal arm 40 close to the rotating shaft 31; the fixed bracket 50 is arranged at one end of the support 30 away from the rotating shaft 31; one end of the switch body 10 of the brake light switch 1 where the moving component 20 is provided penetrates through one end of the fixed bracket 50 away from the support 30, and the moving component 20 is movably connected to the switch bumper 41.

[0059] The brake light switch 1 is assembled on the brake pedal 2. Specifically, the brake light switch 1 is assembled on one end of the fixed bracket 50 away from the support 30. The brake light switch 1 includes a switch body 10, a housing 11, and a moving component 20. The moving component 20 includes a hollow push rod 21, an upper limit block 22, a spring 23, a lower limit block 24, and a ball 25. The hollow push rod 21 and the ball 25 are both movably connected to the switch contact block 41, that is, the hollow push rod 21 and the ball 25 can move in a rolling manner on the switch contact block 41. The rotating shaft 31 sequentially passes through the side plates of the support 30, the pedal arm 40, and the other side plate of the support 30. The pedal arm 40 rotates in an arc trajectory with the rotating shaft 31 as the support center point. A pedal is provided at one end of the pedal arm 40 away from the rotating shaft 31. The pedal is a flat plate for receiving external force, and vertical ribbed grooves are provided thereon. The vertical ribbed grooves are used to increase friction to enhance the stability of the pedal when receiving external force, and this external force can be provided by the foot stepping force or other acting forces.

[0060] When the pedal arm 40 receives an external force, it rotates in an arc trajectory with the rotating shaft 31 as the center, and the switch contact block 41 provided on the pedal arm 40 also rotates in an arc trajectory with the rotating shaft 31 as the center. At the same time, with the rotation of the arc trajectory of the switch contact block 41, the hollow push rod 21, the spring 23, the lower limit block 24, and the ball 25 all perform upward or downward sliding movements, and the ball 25 also performs left or right rolling movements to reduce wear and noise generation and improve the smoothness of movement.

[0061] As Figures 3-4 and Figures 7-8 shown, it is a cross-sectional view of the brake light switch 1 assembled on the brake pedal 2, that is, a structural diagram of the state where the brake light switch 1 is subjected to an external force; Figure 3 and Figure 7 is a structural diagram of the initial state when the brake light switch 1 is subjected to the external force of the switch contact block 41. At this time, the switch contact block 41 has not started to rotate in an arc trajectory with the pedal arm 40, that is, the pedal arm 40 is in a stationary state (i.e., the initial state, the state before starting to move), the switch contact block 41 is in a stationary state, and the brake light switch 1 is in a compressed state.

[0062] Figure 4 and Figure 8It is a structural diagram of the motion state when the brake light switch 1 is subjected to the external force of the switch bump 41. At this time, the switch bump 41 starts to rotate along the downward arc trajectory with the pedal arm 40, that is, the pedal arm 40 is in a moving state, the switch bump 41 is in a moving state, and the brake light switch 1 is in a released state. At the same time, a sensor is also provided inside the brake light switch 1. When the brake light switch 1 is in the released state, this sensor can send a switch signal to the main console of the vehicle for brake prompt processing or clutch shifting processing, that is, the brake pedal 2 including the brake light switch 1 can be used as the brake or clutch of the vehicle. Figure 4 and Figure 8 It is a structural diagram of the motion state when the brake light switch 1 is subjected to the external force of the switch bump 41. At this time, the switch bump 41 starts to rotate along the upward arc trajectory with the pedal arm 40, that is, during the process of the pedal arm 40 moving from the moving state back to the static state, the switch bump 41 moves from the moving state back to the static state, and the brake light switch 1 moves from the released state back to the compressed state.

[0063] It should be noted that for the convenience of understanding, in Figures 7-8 the fixed bracket 50 is not shown. When the brake light switch 1 is in the released state or the compressed state, the hollow push rod 21 and the ball 25 are always connected to the switch bump 41.

[0064] As Figure 3 and Figure 7 shown, when the pedal arm 40 is in the static state, the switch bump 41 is in the static state, and the brake light switch 1 is in the compressed state. Specifically, the switch bump 41 applies an external force to the hollow push rod 21 and the ball 25. The hollow push rod 21 slides upward along the inner wall of the switch body 10, and the ball 25 slides upward along the inner wall of the hollow rod body of the hollow push rod 21. Moreover, the ball 25 pushes the lower limit block 24 to also slide upward along the inner wall of the hollow rod body of the hollow push rod 21, and the lower limit block 24 compresses the spring 23; until the upper limit block 22, the spring 23, the lower limit block 24, and the ball 25 all stop moving. At this time, the spring 23 is in a compressed state.

[0065] As Figure 4 and Figure 8As shown, when the pedal arm 40 is in a moving state, the switch contact block 41 is in a moving state, and the brake light switch 1 is in a released state. Specifically, when an external force is applied to the pedal arm 40, the pedal arm 40 drives the switch contact block 41 to rotate along a downward arc trajectory. The overall movement of the pedal arm 40 and the switch contact block 41 is downward. Therefore, the switch contact block 41 gradually releases the hollow push rod 21 and the ball 25, and the ball 25 moves in a rolling manner on the switch contact block 41. In this way, the hollow push rod 21 moves downward along the inner wall of the switch body 10, the ball 25 moves downward along the inner wall of the hollow rod body of the hollow push rod 21, and the ball 25 pushes the lower limit block 24 to also move downward along the inner wall of the hollow rod body of the hollow push rod 21. The lower limit block 24 gradually releases the spring 23, and at this time, the spring 23 is in a released state. At the same time, when the switch contact block 41 rotates along an arc trajectory, a lateral force is also applied to the ball 25, and the ball 25 starts to roll left or right on the switch contact block 41. That is, the lateral force received by the ball 25 generates a rotational torque that causes the ball 25 to rotate. Therefore, no sliding friction force is generated between the ball 25 and the switch contact block 41, and the lateral force acting on the hollow push rod 21 is also reduced, avoiding the occurrence of noise and wear, and improving the smoothness of use.

[0066] As Figure 4 and Figure 8As shown, during the process of the pedal arm 40 moving from the moving state to the stationary state, during the process of the switch contact block 41 moving from the moving state to the stationary state, and during the process of the brake light switch 1 moving from the released state to the compressed state. Specifically, when an external force is applied to the pedal arm 40, the pedal arm 40 drives the switch contact block 41 to rotate along an upward arc trajectory. The overall movement of the pedal arm 40 and the switch contact block 41 is upward. Therefore, the switch contact block 41 gradually pushes the hollow push rod 21 and the ball 25 upward, and the ball 25 rolls on the switch contact block 41. In this way, the hollow push rod 21 slides upward along the inner wall of the switch body 10, the ball 25 slides upward along the inner wall of the hollow rod body of the hollow push rod 21, and the ball 25 also pushes the lower limit block 24 to slide upward along the inner wall of the hollow rod body of the hollow push rod 21, and the lower limit block 24 gradually compresses the spring 23. Until the pedal arm 40 and the switch contact block 41 both stop moving, at this time, the spring 23 returns to the compressed state. At the same time, when the switch contact block 41 rotates along an arc trajectory, a lateral force is also applied to the ball 25, and the ball 25 starts to roll left or right. That is, the lateral force received by the ball 25 generates a rotational torque that causes the ball 25 to rotate. Therefore, no sliding friction is generated between the ball 25 and the switch contact block 41, and the lateral force acting on the hollow push rod 21 is also reduced, avoiding the occurrence of noise and wear, and improving the smoothness of use.
