[0024] Embodiment 1

[0025] like Figure 1 and Figure 4 As shown, this embodiment provides a device for displaying the braking strength of a car, including: a gear switch, a power source 10 and a light-emitting element 91, wherein the gear switch includes a housing 1, a slider 2 and a plurality of pairs of contacts 31, wherein the slider 2 is movably connected to the housing 1, and two contacts 31 in a pair of contacts 31 are electrically connected to the power source 10 and the light-emitting element 91 respectively, and each pair of contacts 31 is electrically connected to a different light-emitting element 91 respectively. The movably connected means that the slider 2 moves relative to the housing 1, including sliding and rotating.

[0026] Based on the above technical solution, the slider 2 electrically connects the multiple pairs of contacts 31 in sequence when moving in the forward direction, and disconnects the electrically connected contacts 31 when moving in the reverse direction.

[0027] Preferably, the light emitting elements 91 are arranged in sequence in the order in which the corresponding contacts 31 are electrically connected so as to light up in sequence during braking. The light emitting elements 91 can be arranged along a ring, a curve, or a straight line.

[0028] Preferably, the light emitting element 91 is a light bulb, and one light emitting element 91 includes one or more light bulbs. When the driver gradually increases the braking force (i.e., the rotation angle of the pedal 7 gradually increases or the manual / automatic driving slider 2 moves forward), the number of electrically connected contacts 31 gradually increases, so that the number of light emitting elements 91 that are powered on and illuminated gradually increases until all the light emitting elements 91 are illuminated. The gear switch quantitatively displays the braking strength of the car by controlling the number of illuminated light emitting elements 91, thereby notifying the driver of the following car to take corresponding measures to reduce the occurrence of traffic accidents.

[0029] On the basis of the above technical solution, a connecting member 5 is further included, and two ends of the connecting member 5 are respectively connected to the slider 2 and the brake pedal 7.

[0032] Based on the above technical solution, the slider 2 is a conductor, and a plurality of pairs of contacts 31 are fixedly connected to the housing 1, and the slider 2 is slidably connected to the contacts 31. Figure 1 As shown, the pedal 7 rotates to drive the slider 2 to move to the left through the connecting member 5. As the pedal 7 is stepped on more, the slider 2 contacts with multiple pairs of contacts 31 in sequence, and the slider 2 conducts electricity to electrically connect the pairs of contacts 31 in sequence, and the corresponding light-emitting elements 91 light up in sequence.

[0033] Embodiment 2

[0034] like Figure 2 and Figure 3 As shown, this embodiment provides a device for displaying the braking strength of a car, including: a gear switch, a power source 10 and a light-emitting element 91, wherein the gear switch includes a housing 1, a slider 2 and a plurality of pairs of contacts 31, wherein the slider 2 is movably connected to the housing 1, and two contacts 31 in a pair of contacts 31 are electrically connected to the power source 10 and the light-emitting element 91 respectively, and each pair of contacts 31 is electrically connected to a different light-emitting element 91 respectively. The movably connected means that the slider 2 moves relative to the housing 1, including sliding and rotating.

[0035] Based on the above technical solution, the slider 2 electrically connects the multiple pairs of contacts 31 in sequence when moving in the forward direction, and disconnects the electrically connected contacts 31 when moving in the reverse direction.

[0036] Preferably, the light emitting elements 91 are arranged in sequence in the order in which the corresponding contacts 31 are electrically connected so as to light up in sequence during braking. The light emitting elements 91 can be arranged along a ring, a curve, or a straight line.

[0037] Preferably, the light emitting element 91 is a light bulb, and one light emitting element 91 includes one or more light bulbs. When the driver gradually increases the braking force (i.e., the rotation angle of the pedal 7 gradually increases or the manual / automatic driving slider 2 moves forward), the number of electrically connected contacts 31 gradually increases, so that the number of light emitting elements 91 that are powered on and illuminated gradually increases until all the light emitting elements 91 are illuminated. The gear switch quantitatively displays the braking strength of the car by controlling the number of illuminated light emitting elements 91, thereby notifying the driver of the following car to take corresponding measures to reduce the occurrence of traffic accidents.

[0038] On the basis of the above technical solution, a connecting member 5 is further included, and two ends of the connecting member 5 are respectively connected to the slider 2 and the brake pedal 7.

[0039] Preferably, the light emitting element 91 is located inside the brake combination tail light 9 , and the brake combination tail light 9 is located at the rear of the vehicle body 8 , and the brake combination tail light 9 is used to protect the light emitting element 91 .

[0040] Based on the above technical solution, each pair of contacts 31 is located in a micro switch 3, the shell of the micro switch 3 is fixedly connected to the housing 1, and the button of the micro switch 3 is slidably connected to the slider 2. The paired contacts 31 can be both fixed relative to the housing 1, or one contact 31 can be fixed and the other contact 31 can be movable.

[0041] On the basis of the above technical solution, it further comprises a track 6 , wherein the track 6 is fixedly connected to the housing 1 , and the slider 2 is slidably connected to the track 6 .

[0042] Based on the above technical solution, an elastic element 4 is further included, the two ends of which are fixed relative to the housing 1 and the slider 2, respectively, and the elastic element 4 is used to drive the slider 2 to move in the opposite direction. The elastic element 4 can be a spring.

[0043] Based on the above technical solution, the slider 2 moves linearly along the track 6 , and the plurality of micro switches 3 are arranged linearly along the moving direction of the slider 2 .

[0044] On the basis of the above technical solution, the connecting member 5 is a pull rope, and the two ends of the connecting member 5 are respectively rotatably connected or fixedly connected to the slider 2 and the brake pedal 7.

[0045] Based on the above technical solution, the connecting member 5 is a hard rod, and the two ends of the connecting member 5 are respectively rotatably connected to the slider 2 and the brake pedal 7, the connecting member 5 is rotatably connected to the slider 2 and slidably connected to the brake pedal 7, or the connecting member 5 is rotatably connected to the slider 2 and contacts the brake pedal 7.

[0046] Based on the above technical solution, a guide slope 21 is formed on the slider 2 near the micro switch 3 .

[0047] like Figure 2 As shown, the gear switch is located above the brake pedal 7. When the brake pedal 7 is stepped on, the brake pedal 7 pulls the connecting member 5, and the connecting member 5 pulls the slider 2 to move toward the micro switch 3. During the forward movement process, the connecting member 5 gradually presses the micro switch 3, closes the two contacts 31 in the micro switch 3, and makes the light-emitting element 91 light up.

[0048] When the slider 2 is reset, the elastic element 4 pulls the slider 2 to move in the opposite direction, the slider 2 is separated from the contact with the micro switch 3, the micro switch 3 is reset (depending on the reset spring inside it), and the light emitting element 91 is extinguished in turn. Due to the reset force provided by the elastic element 4, the connecting member 5 can be a pull rope or a hard rod.

[0049] Among them, when Figure 2 When the connecting member 5 is a hard rod, the elastic element 4 may not be used.

[0050] like Figure 3 As shown, the gear switch is located below the brake pedal 7. When the brake pedal 7 is stepped on, the brake pedal 7 pulls the connecting member 5, and the connecting member 5 pushes the slider 2 downward to move toward the micro switch 3. During the forward movement process, the connecting member 5 gradually presses the micro switch 3, closes the two contacts 31 in the micro switch 3, and makes the light-emitting element 91 light up.

[0051] When the slider 2 is reset, the connecting member 5 pulls the slider 2 to move in the opposite direction, and the slider 2 is separated from the micro switch 3 in turn, and the light element 91 is extinguished in turn. In this case, the connecting member 5 can only be a hard rod, and the compressed elastic element 4 also pushes the slider 2 to move in the opposite direction, playing an auxiliary role.

[0052] When the connecting member 5 contacts the slider 2 only when pressed down, and the connecting member 5 is separated from the slider 2 when the slider 2 is reset, the elastic element 4 needs to be used to provide the reset force.

[0053] It should be noted that the above Figure 2 and Figure 3 In the implementation mode, the micro switches 3 all adopt normally open switches with reset.

[0054] In an embodiment not shown in the figure, a normally closed micro switch 3 is used. When the brake pedal 7 is not applied, the slider 2 contacts the normally closed micro switch 3, disconnecting its contact 31. When the brake pedal 7 is pressed down, the slider 2 is disconnected from the micro switch 3, the micro switch 3 is reset, and the contact 31 is electrically connected, so that the light emitting element 91 is powered on and emits light.

[0055] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
