Description

Technical Field

[0001] The invention belongs to the technical field of vehicles, and in particular relates to an overload safety protection system for amusement park vehicles. Background Art

[0002] Electric park vehicles are regional vehicles, specially developed for self-driving tours, regional patrols, and transportation in tourist attractions, parks, large amusement parks, closed communities, campuses, garden hotels, resorts, villa areas, city pedestrian streets, ports and other areas. They are environmentally friendly electric passenger vehicles.

[0003] At present, when using this type of electric park vehicles, some tourists do not ride according to the prescribed number of people, resulting in overloading. This phenomenon will affect the service life of the vehicle, and will also lead to frequent safety accidents and pose a safety hazard. Summary of the invention

[0004] Aiming at the drawbacks of the prior art that amusement park vehicles are easily overloaded, which affects their service life and causes potential safety hazards, the present invention provides an amusement park vehicle overload safety protection system, which can sound an alarm when the amusement park vehicle is overloaded to remind users to pay attention.

[0005] The invention objective of the present invention is achieved through the following technical scheme: a garden car overload safety protection system, including a main frame, a rear frame rotatably connected to the main frame, a first controller, and an alarm, wherein a shock absorber is provided between the main frame and the rear frame to provide resistance to the relative rotation between the main frame and the rear frame; a sensor for detecting the relative position between the main frame and the rear frame is also installed on the main frame or the rear frame, and the sensor and the alarm are electrically connected to the first controller respectively. In the above scheme, when the garden car is overloaded, a certain amplitude of relative rotation will occur between the main frame and the rear frame, and when the sensor detects that the relative position between the main frame and the rear frame reaches a set value, the first controller detects the signal of the sensor, and the first controller controls the alarm to sound an alarm to remind the user that the garden car is overloaded, thereby avoiding shortening the service life of the garden car due to overloading and reducing safety hazards.

[0006] Preferably, both ends of the shock absorber are rotatably connected to the main frame and the rear frame respectively.

[0007] Preferably, the main frame includes a chassis, the rear end of the chassis is rotatably connected to the rear frame, a connecting frame extending toward the upper side of the rear frame is fixedly provided on the chassis, the sensor is fixedly provided on the connecting frame, the sensor is a photoelectric sensor with a groove structure, a connecting rod is fixedly provided on the rear frame, a baffle is fixedly provided on the connecting rod, and the baffle can pass through the sensor as the main frame and the rear frame rotate relative to each other. When the amusement park vehicle is overloaded, as the main frame and the rear frame rotate relative to each other to a certain amplitude, the baffle moves into the groove of the sensor, and the feedback signal transmitted by the sensor to the first controller changes, which is now an overload state, and the first controller controls the alarm to work. The relative rotation amplitude between the main frame and the rear frame depends on the load on the amusement park vehicle.

[0008] Preferably, the alarm is a buzzer, and the alarm and the first controller are fixedly arranged on the connecting frame, and a timer is arranged inside the first controller. When the amusement park vehicle passes through a speed bump or because of road bumps, a large relative rotation will occur between the main frame and the rear frame, and at this time the baffle may move into the groove of the sensor. Under the action of the shock absorber, the rotation amplitude between the main frame and the rear frame will be reduced to a balanced state, and at this time the baffle leaves the groove of the sensor. In this state, the amusement park vehicle is not overloaded, but the sensor will also feed back a corresponding signal to the first controller, which may cause the alarm to issue a false alarm. In view of this phenomenon, the present application sets a timer, and only when the sensor is continuously blocked by the baffle and continuously transmits a signal to the first controller for a certain period of time, the first controller will control the alarm to work.

[0009] Preferably, there are two shock absorbers, which are symmetrically arranged. Symmetrically arranged shock absorbers have better shock absorbing effect.

[0010] Preferably, the shock absorber includes a guide sleeve rotatably connected to the connecting frame and a guide rod rotatably connected to the rear frame, the guide rod is sleeved in the guide sleeve and can slide along the length direction of the guide sleeve, a first limit block is fixedly provided on the guide sleeve, a second limit block is fixedly provided on the guide rod, a spring is provided between the first limit block and the second limit block, and the guide sleeve and guide rod are sleeved in the spring.

[0011] Preferably, the connecting frame includes two vertical rods fixed on the main frame, an arc rod bent toward the rear side of the main frame is fixed to the upper end of the vertical rod, a cross rod parallel to the chassis is fixed to the other end of the arc rod, a reinforcing rod is fixed between the two arc rods, and a cross beam is fixed between the two cross rods.

[0012] Preferably, the upper end of the guide sleeve is rotatably connected to the cross beam, and the lower end of the guide rod is hinged to the rear frame.

[0013] Preferably, the sensor is fixedly arranged on the reinforcing rod, and the baffle is located below the connecting frame.

[0014] Preferably, a motor for driving the amusement park vehicle is fixedly provided on the rear frame, and a second controller is fixedly provided on the main frame, and the second controller is electrically connected to the first controller and the motor respectively. When the first controller determines that the amusement park vehicle is overloaded through the signal fed back by the sensor, the first controller controls the alarm to sound an alarm, and at the same time, the first controller transmits a signal to the second controller, and the second controller controls the motor to reduce the speed, thereby reducing the driving speed of the amusement park vehicle, which is safer.

[0015] Preferably, the first controller is a single chip microcomputer controller.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the present invention can play the role of overload warning, and can also automatically control the vehicle speed to decrease, thereby improving safety performance and extending the service life of the vehicle.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0022] Example 1

[0023] like Figure 1 , Figure 2 , Figure 3As shown, a system for protecting amusement park vehicles from overloading comprises a main frame 1, a rear frame 2, a first controller 3 and an alarm 4. The main frame 1 comprises a chassis 5, the rear end of the chassis 5 is rotatably connected to the rear frame 2, a connecting frame 6 extending upwardly toward the rear frame 2 is fixedly provided on the chassis 5, the connecting frame 6 comprises two vertical rods 7 fixed on the main frame 1, an arc rod 8 bent toward the rear side of the main frame 1 is fixedly provided on the upper end of the vertical rod 7, a cross rod 9 parallel to the chassis 5 is fixedly provided on the other end of the arc rod 8, a reinforcing rod 10 is fixedly provided between the two arc rods 8, and a cross beam 11 is fixedly provided between the two cross rods 9.

[0024] Two shock absorbers 12 are provided between the main frame 1 and the rear frame 2 to provide resistance to the relative rotation between the main frame 1 and the rear frame 2. The two shock absorbers 12 are symmetrically arranged. The shock absorber 12 includes a guide sleeve 13 rotatably connected to the connecting frame 6 and a guide rod 14 rotatably connected to the rear frame 2. The upper end of the guide sleeve 13 is rotatably connected to the crossbeam 11, and the lower end of the guide rod 14 is hinged to the rear frame 2. The guide rod 14 is sleeved in the guide sleeve 13 and can slide along the length direction of the guide sleeve 13. A first limit block 15 is fixedly provided on the guide sleeve 13, and a second limit block 16 is fixedly provided on the guide rod 14. A spring 17 is provided between the first limit block 15 and the second limit block 16. The guide sleeve 13 and the guide rod 14 are sleeved in the spring 17.

[0025] A sensor 18 for detecting the relative position between the main frame 1 and the rear frame 2 is also fixedly provided on the reinforcing rod 10 of the connecting frame 6. The sensor 18 is fixedly arranged on the connecting frame 6. The sensor 18 is a photoelectric sensor 18 with a groove structure. A connecting rod 19 is fixedly provided on the rear frame 2. A baffle 20 located below the connecting frame 6 is fixedly provided on the connecting rod 19. As the main frame 1 and the rear frame 2 rotate relative to each other, the baffle 20 can pass through the sensor 18.

[0026] The first controller 3 is a single chip microcomputer controller. The alarm 4 is a buzzer. The alarm 4 and the first controller 3 are fixedly arranged on the connecting frame 6. A timer 21 is arranged inside the first controller 3. The sensor 18 and the alarm 4 are electrically connected to the first controller 3 respectively. A motor 22 for driving the amusement park vehicle is fixedly arranged on the rear frame 2. A second controller 23 is also fixedly arranged on the main frame 1. The second controller 23 is electrically connected to the first controller 3 and the motor 22 respectively. The second controller 23 is an existing controller of the vehicle itself, and there is no need to set up another controller.

[0027] When the present invention is installed on a garden car for use, the main frame 1 and the rear frame 2 constitute the frame part of the vehicle, and wheels are respectively installed on the main frame 1 and the rear frame 2. As the weight of the people carried on the garden car increases, the relative angle between the main frame 1 and the rear frame 2 will change, and the baffle will gradually approach the sensor 18. When the baffle moves to the groove position of the sensor 18, the sensor 18 generates a signal and sends it to the first controller 3. The first controller 3 receives the signal from the sensor 18 and analyzes the input signal in combination with the timer 21. The timer 21 inside the first controller 3 starts working. When the input signal lasts for 10 seconds or more, the first controller 3 determines that it is overloaded. The first controller 3 outputs a signal to control the alarm 4 to sound an alarm to prompt overload. At the same time, the first controller 3 sends a signal to the second controller 23, and the second controller 23 controls the motor 22 to reduce the rotation speed, thereby reducing the vehicle's driving speed. At this time, overload can be avoided and safety performance is improved. If the first controller 3 receives the input signal from the sensor 18 for less than 10 seconds, it may be due to the indirect operation of the sensor 18 caused by road bumps or speed bumps, so the first controller 3 will not judge that it is overloaded. This effectively avoids misjudgment. The judgment time of the first controller 3 can be preset by the program inside the first controller 3 and can be adjusted according to time usage requirements.

[0028] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
