Description

Technical Field

[0001] This utility model relates to the field of warning device technology, and in particular to a start and brake warning device inside a bus. Background Technology

[0002] With the increasing popularity of buses, more and more people are choosing to take them, which has led to a number of problems.

[0003] During rush hour, when there are many passengers, many people have no seats and have to stand. The sudden starts and stops of buses can easily cause standing passengers to lose their balance, which can result in minor collisions with others or even serious injuries. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where sudden starts and stops of buses can easily cause standing passengers to lose their balance, resulting in minor collisions with others or serious injuries. Therefore, this invention proposes a start and stop warning device for buses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bus start / brake warning device includes a brake pedal, an accelerator pedal, and a handrail located inside the vehicle, and further includes:

[0007] A pad is installed inside the vehicle, the pad being located on one side of the brake pedal and the accelerator pedal;

[0008] The pad block contains a pressure sensor for detecting pressure, and a wireless signal transmitter electrically connected to the pressure sensor is also fixed inside the pad block. A U-shaped frame is fitted on the surface of the handrail, and a warning device for alerting passengers is fixed on the surface of the U-shaped frame. A wireless signal receiver electrically connected to the warning device is fixed inside the U-shaped frame. The wireless signal transmitter and the wireless signal receiver are used in conjunction.

[0009] The U-shaped frame is equipped with a set of connecting components, which are used to quickly fix the U-shaped frame to the surface of the handrail.

[0010] In one possible design, the connecting assembly includes a first groove and a second groove formed within a U-shaped frame, with a nut fixed in the second groove and a screw threadedly connected to the nut in the first groove, the screw and the surface of the handrail making contact through compression.

[0011] In one possible design, a rotating ring is rotatable within the first groove. The rotating ring is sleeved on the surface of the screw. Two limiting grooves are formed on the surface of the screw. Two limiting blocks are fixed inside the rotating ring, and the two limiting blocks slide within the two limiting grooves respectively.

[0012] In one possible design, an anti-slip pad is fixed inside the U-shaped frame.

[0013] In one possible design, the warning device is an LED light that emits red light.

[0014] In one possible design, the underside of the pad is provided with a connecting plate, the bottom end of which is coated with adhesive for connecting to the vehicle body, the top end of which is fixed with hook and loop fasteners, and the bottom end of the pad is fixed with hook and loop fasteners, the hook and loop fasteners overlapping each other.

[0015] In this application, when in use, the U-shaped frame is fitted onto the surface of the handrail, and then the screw is turned so that the screw thread is connected to the nut, thereby fixing the U-shaped frame to the handrail. A limit block slides in the limit groove opened on the surface of the screw, and the limit block can effectively prevent the screw from detaching from the U-shaped frame.

[0016] When a bus driver brakes, he needs to remove his foot from the accelerator pedal and press the brake pedal. When the foot is removed from the accelerator pedal, the pressure sensor detects the pressure change and converts it into an electrical signal, which is then transmitted to the radio signal transmitter. The radio signal transmitter transmits the signal to the radio signal receiver, which then activates the warning device to alert passengers and ensure that they are prepared.

[0017] Beneficial effects: In this utility model, the bus start and brake indication device detects pressure changes through a pressure sensor, which can determine the vehicle's start and brake status in real time, thus improving passenger safety.

[0018] In this invention, the driver's actions are used as the criterion for predicting the bus's operating status, achieving a "predictive" effect with small errors and a long lead time. Furthermore, the introduction of wireless sensing into the warning system results in a highly efficient and low-cost device that can be installed immediately on buses without requiring the device to be returned to the factory for replacement.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: Refer to Figures 1-5 A bus start-and-brake warning device, applied in the field of warning device technology, includes a brake pedal 1, an accelerator pedal 2, and a handrail 5 installed inside the vehicle. To detect brake and accelerator operation, a pad 3 is also fixed inside the vehicle, located on one side of the brake pedal 1 and the accelerator pedal 2.

[0029] A pressure sensor 4 for detecting pressure is fixed inside the pad 3. When the accelerator pedal 2 is released, it releases the pressure on the pressure sensor 4. After the pressure sensor 4 detects the loss of pressure, a wireless signal transmitter electrically connected to the pressure sensor 4 is also fixed inside the pad 3. When the pressure sensor 4 detects a change in pressure, the wireless signal transmitter will emit a wireless signal.

[0030] A U-shaped frame 6 is fitted onto the surface of the handrail 5, and a warning device 7 for alerting passengers is fixed to the surface of the U-shaped frame 6. In this embodiment, the warning device 7 is an LED light that emits red light to attract the attention of passengers. A wireless signal receiver electrically connected to the warning device 7 is fixed inside the U-shaped frame 6. The wireless signal transmitter and the wireless signal receiver work together. When the wireless signal receiver receives a wireless signal, it activates the warning device 7. The structure and mechanism of the pressure sensor 4, the wireless signal receiver, and the wireless signal transmitter are the same as those in the patent with publication number CN217505818U.

[0031] To facilitate quick and easy attachment of the U-shaped frame 6 to the surface of the handrail 5, a set of connecting components is provided inside the U-shaped frame 6. This connecting component includes a first groove 13 and a second groove 14 formed within the U-shaped frame 6. A nut 8 is fixed within the second groove 14, and a screw 9, threadedly connected to the nut 8, is provided within the first groove 13. By rotating the screw 9, it can be pressed into contact with the surface of the handrail 5, thereby securing the U-shaped frame 6.

[0032] Example 2: Refer to Figures 1-5 An improvement upon Embodiment 1: To further facilitate the rotation of the screw 9, a rotating ring 11 is rotatably mounted within the first groove 13, and the rotating ring 11 is fitted onto the surface of the screw 9. Two limiting grooves 10 are formed on the surface of the screw 9, and two limiting blocks 12 are fixed within the rotating ring 11, with the two limiting blocks 12 sliding within the two limiting grooves 10 respectively. Thus, rotating the rotating ring 11 drives the screw 9 to rotate, effectively preventing the screw 9 from detaching.

[0033] To increase the friction between the U-shaped frame 6 and the handrail 5 and prevent the U-shaped frame 6 from sliding, an anti-slip pad 15 is fixed inside the U-shaped frame 6. The anti-slip pad 15 can effectively improve the stability of the U-shaped frame 6 and ensure that it will not slip due to vehicle shaking during use.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
