Description

Technical Field

[0001] This utility model relates to the field of sightseeing vehicle technology, and in particular to a safety early warning and protection device for tourist sightseeing vehicles. Background Technology

[0002] Existing sightseeing vehicles are mostly used in open or semi-open road environments such as scenic spots, parks, and city sightseeing. Due to the complex environment, dense pedestrians, numerous obstacles, and varying road conditions, safety issues are receiving increasing attention. In order to improve the driving safety of sightseeing vehicles, it is necessary to effectively protect the vehicle body to reduce the risk of accidents and ensure the safety of people and vehicles.

[0003] In existing technologies, such as the "Safety Early Warning and Protection Device for Tourist Sightseeing Vehicles" with announcement number CN222422287U, a lead-acid battery is included, along with a casing, a protective mechanism, and an electrolyte adding mechanism. The lead-acid battery is fixedly connected inside the casing, and an electrolyte adding mechanism is located above the lead-acid battery. A protective mechanism for protecting the lead-acid battery is located on the outside of the casing. Although this technology, through the structural design of the electrolyte adding mechanism, can store a certain amount of electrolyte inside the storage tank, and quantitatively add electrolyte to the lead-acid battery when the electrolyte inside is insufficient, effectively improving the practicality of the device, this technology is consistent with traditional methods. The problem is that most sightseeing vehicles in the current technology focus only on basic driving functions in their design and usually lack structural protective devices to deal with the risk of sudden collisions. Especially when the vehicle is running at low speed, the driver often has difficulty in noticing obstacles in time due to limited visibility, blind spots when turning, or complex environment, which leads to frequent collision accidents. On the one hand, the vehicle lacks an effective buffer structure before contacting the obstacle, making it very easy to have a direct collision, resulting in damage to the vehicle body and even endangering the safety of people. On the other hand, even if a protective mechanism is installed, it is often not structurally linked with the alarm mechanism, and cannot issue a warning at the same time during a collision to remind the driver that the road ahead is too narrow or there are obstacles that make it difficult to pass. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a safety warning and protection device for tourist sightseeing vehicles, so as to solve the problem of existing sightseeing vehicles lacking protection and safety warning.

[0005] Based on the above objectives, this utility model provides a safety warning and protection device for sightseeing vehicles, including a vehicle body. A protective component is installed on the top of the vehicle body to protect the vehicle body from impacting an obstacle. The protective component includes two connecting cylinders fixedly connected to the top of the vehicle body. A crash plate is slidably engaged with one end of each connecting cylinder. An alarm component is installed on the top of the vehicle body to issue an alarm when the protective component impacts an object. The alarm component works in conjunction with the protective component to provide a safety warning for the sightseeing vehicle. The alarm component includes two guide plates and two fixing boxes fixedly connected to the top of the vehicle body. A rack is slidably engaged with one side of each guide plate, and a first gear is meshed with one side of the rack.

[0006] Preferably, a protective pad is fixedly connected to one end of the anti-collision plate, the length of the anti-collision plate at one end of the protective pad should protrude beyond the front of the vehicle body, and the distance between the edges of the two protective pads is greater than the width of the vehicle body.

[0007] Preferably, a plurality of return springs are fixedly connected inside the connecting cylinder, and one end of the return spring is fixedly connected to one end of the anti-collision plate.

[0008] Preferably, a connecting rod is fixedly connected to one end of the anti-collision plate inside the connecting cylinder, and the end of the connecting rod away from the anti-collision plate passes through one end of the connecting cylinder and is fixedly connected to one end of the rack.

[0009] Preferably, a positioning post and a positioning rod are fixedly connected inside the fixed box. The positioning rod is located in the middle of the fixed box. A sector plate is rotatably engaged on the top of the positioning post. A movable groove is opened on one side of the fixed box. An alignment plate is fixedly connected to one end of the sector plate that passes through the movable groove. The position of one end of the alignment plate corresponds to the position of one end of the lever. When the lever rotates, it moves the alignment plate.

[0010] Preferably, the end of the sector plate away from the alignment plate has a toothed groove, and the inside of the fixing box is rotatably connected to a second gear via a shaft. One end of the toothed groove of the sector plate meshes with the outside of the second gear. A third gear is fixedly connected to the top of the second gear, and a fourth gear is rotatably engaged with the outside of the top of the positioning rod. One side of the third gear meshes with one side of the fourth gear, and the tooth ratio of the third gear is greater than that of the fourth gear.

[0011] Preferably, a connecting shaft is rotatably engaged on the top of the positioning rod, the bottom of the connecting shaft is fixedly connected to the top of the fourth gear, and the bottom of the sound cover is fixedly connected to the top of the positioning rod.

[0012] Preferably, clamps are symmetrically fixedly connected to both sides of the connecting shaft, and a limiting post is fixedly connected inside the clamp.

[0015] The beneficial effects of this utility model are:

[0016] 1. Through the installation of protective and alarm components, the sightseeing vehicle possesses significant passive protection and early warning functions during operation. When the front of the vehicle is about to contact an obstacle, the anti-collision plate installed at the front of the vehicle body, under the force of compression, can drive the gear set to rotate through the connecting structure and drive the alarm structure to activate, thereby achieving buffering and energy absorption of the obstacle and synchronous audible warning. This avoids the risk of collision caused by blind spots or lack of concentration of the driver. The entire device adopts a fully mechanical structure, requiring no external power supply or complex control system. It has the advantages of simple structure, sensitive action, reliable linkage, and reusability, thus improving the safety protection of sightseeing vehicles in complex road environments.

[0017] 2. Through the installation of protective components, a connecting cylinder and a sliding anti-collision plate are installed at the front of the vehicle. The front end of the anti-collision plate is equipped with a buffer protective pad, which can effectively absorb the impact force when the vehicle is hit by a frontal collision, reducing the risk of vehicle damage and personal injury. The anti-collision plate is connected to the rack and pinion structure through a connecting rod and has a linkage alarm function. At the same time, it can automatically reset after a collision with the help of a return spring, improving the reliability and reusability of the structure. The distance between the two anti-collision plates is greater than the width of the vehicle body, which can make contact with obstacles in advance when the vehicle does not make frontal contact with obstacles, realizing the role of early detection and buffer protection, and improving driving safety.

[0018] 3. The alarm components utilize a sliding anti-collision plate to rotate a rack and pinion gear, which in turn drives a linkage shaft via a lever plate. This causes a striking ring mounted on the linkage shaft to strike the inner wall of the sound cover under centrifugal force, producing a distinct mechanical alarm sound. This achieves a fully mechanical early warning system without the need for a power source. The structure is highly responsive, operates smoothly, and features a compact design, stable operation, and low false alarm rate. It also includes a reset spring structure, allowing for automatic reset after the alarm is completed. This design is suitable for repeated use and meets the passive safety warning needs of sightseeing vehicles in complex outdoor environments. Furthermore, the use of a belt pulley to drive the rotating paddle further visually alerts the driver to obstacles or impassable terrain. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] Such as this utility model Figures 1 to 5 The present invention provides a safety warning and protection device for a sightseeing vehicle, including a vehicle body 1. A protective component is provided on the top of the vehicle body 1 for protecting the vehicle body 1 from collision with an obstacle. The protective component includes two connecting cylinders 2 fixedly connected to the top of the vehicle body 1. A crash plate 3 is slidably engaged at one end of the connecting cylinder 2. An alarm component is provided on the top of the vehicle body 1. The alarm component is used to issue an alarm when the protective component hits an object. The alarm component works in conjunction with the protective component to provide a safety warning for the sightseeing vehicle. The alarm component includes two guide plates 5 fixedly connected to the top of the vehicle body 1 and two fixing boxes 12. A rack 6 is slidably engaged on one side of the guide plate 5. A first gear 9 is meshed on one side of the rack 6. The bottom of the first gear 9 is rotatably connected to the top of the vehicle body 1 via a shaft. A fixing post 10 is fixedly connected to the top of the first gear 9. A lever 11 is fixedly connected to one side of the top of the fixing post 10. A sound cover 26 is installed on the top of the fixing box 12. The sound cover 26 is located on one side of the first gear 9.

[0030] With the addition of protective and alarm components, the sightseeing vehicle possesses significant passive protection and early warning functions during operation. When the front of the vehicle is about to contact an obstacle, the anti-collision plate 3 located at the front of the vehicle body 1, under compression, can drive the gear set to rotate through the connecting structure and activate the alarm structure, thereby achieving buffering and energy absorption of the obstacle and simultaneous audible warning. This avoids the risk of collision caused by blind spots or inattention of the driver. The entire device adopts a fully mechanical structure, requiring no external power supply or complex control system. It has the advantages of simple structure, sensitive action, reliable linkage, and reusability, thus improving the safety of sightseeing vehicles in complex road environments.

[0031] like Figures 1 to 3 As shown, a protective pad 4 is fixedly connected to one end of the anti-collision plate 3. The length of the anti-collision plate 3 at one end of the protective pad 4 should protrude beyond the front of the vehicle body 1, and the distance between the edges of the two protective pads 4 is greater than the width of the vehicle body 1. Multiple return springs 8 are fixedly connected inside the connecting cylinder 2, and one end of the return spring 8 is fixedly connected to one end of the anti-collision plate 3.

[0032] By incorporating protective components, including a connecting cylinder 2 and a sliding anti-collision plate 3 at the front of the vehicle, with a buffer pad 4 at the front end of the anti-collision plate 3, the vehicle can effectively absorb impact force during a frontal collision, reducing damage to the vehicle body 1 and the risk of injury to occupants. The anti-collision plate 3 is connected to the rack 6 via a connecting rod 7, providing a linkage alarm function. It also automatically resets after a collision using a return spring 8, improving structural reliability and reusability. The distance between the two anti-collision plates 3 is greater than the width of the vehicle body 1, allowing for earlier contact with obstacles when the vehicle is not directly facing them, achieving early detection and buffer protection, thus enhancing driving safety. The spacing between the two buffer pads 4 is also designed to mitigate these impacts. This design ensures that when vehicle 1 is unable to determine whether it can pass through the road or obstacles ahead, the protective pad 4 will first contact the obstacle, causing the anti-collision plate 3 to retract, thus protecting vehicle 1. Simultaneously, the retraction of the anti-collision plate 3 will trigger the rear alarm component, alerting the driver that the road ahead is impassable. Furthermore, the return spring 8 retracts when the anti-collision plate 3 retracts, buffering the impact and facilitating subsequent return to its original position, allowing the protective components to be used repeatedly and for extended periods. The protective pad 4 also protects the anti-collision plate 3.

[0033] like Figures 1 to 3 As shown, a connecting rod 7 is fixedly connected to one end of the anti-collision plate 3 inside the connecting cylinder 2, and the end of the connecting rod 7 away from the anti-collision plate 3 passes through the connecting cylinder 2 and is fixedly connected to one end of the rack 6.

[0034] When the anti-collision plate 3 is impacted, the connecting rod 7 moves along with the anti-collision plate 3, thereby triggering the alarm component to sound an alarm.

[0035] like Figures 1 to 4 As shown, a positioning post 14 and a positioning rod 18 are fixedly connected inside the fixed box 12. The positioning rod 18 is located in the middle of the fixed box 12. A sector plate 13 is rotatably engaged on the top of the positioning post 14. A movable groove 30 is provided on one side of the fixed box 12. An alignment plate 15 is fixedly connected to one end of the sector plate 13 that passes through the movable groove 30. The position of one end of the alignment plate 15 corresponds to the position of one end of the lever 11. When the lever 11 rotates, it moves the alignment plate 15.

[0036] The alarm components utilize a sliding anti-collision plate 3 to drive the rack 6 to rotate, which in turn drives the alignment plate 15 via a lever 11 to rotate the connecting shaft 25. This causes the striking ring 23 mounted on the connecting shaft 25 to strike the inner wall of the sound cover 26 under centrifugal force, emitting a clear mechanical alarm sound. This achieves a fully mechanical early warning system without the need for a power source. The structure is highly responsive, operates smoothly, and features a compact design, stable operation, and low false alarm rate. It also includes a reset spring structure, allowing for automatic reset after the alarm is completed. This design is suitable for repeated use and meets the passive safety warning needs of sightseeing vehicles in complex outdoor environments. Additionally, a belt pulley drives the rotating paddle 29 for further operation. The rotation also serves as a visual reminder to the driver that the road ahead is impassable or that there is an obstacle blocking the way. When the connecting rod 7 moves, it will drive the rack 6 to move, and at the same time drive the first gear 9 to rotate. At this time, by setting the position of the lever 11 to correspond to the position of the alignment plate 15, the lever 11 will rotate and move the alignment plate 15. Since the sector plate 13 is rotated and locked to the outside of the positioning post 14, when the alignment plate 15 moves, it will drive the other end of the sector plate 13 to rotate around the positioning post 14 as the base point, which will cause the subsequent linkage mechanism to cause the knocking ring 23 to knock on the sound cover 26 to make a sound, thereby achieving the alarm function.

[0037] like Figures 2 to 4 As shown, the sector plate 13 has a toothed groove at one end away from the alignment plate 15. The inside of the fixing box 12 is rotatably connected to the second gear 19 via a shaft. One end of the toothed groove of the sector plate 13 meshes with the outside of the second gear 19. The top of the second gear 19 is fixedly connected to the third gear 20. The top of the positioning rod 18 is rotatably engaged with the fourth gear 21. One side of the third gear 20 meshes with one side of the fourth gear 21. The tooth ratio of the third gear 20 is greater than the tooth ratio of the fourth gear 21.

[0038] With the third gear 20 and the fourth gear 21 set, when the sector plate 13 rotates, it will drive the second gear 19 to rotate. At this time, the third gear 20 will drive the fourth gear 21 to rotate. By setting the gear ratio of the third gear 20 to be greater than the gear ratio of the fourth gear 21, the third gear 20 will drive the fourth gear 21 to rotate rapidly, thereby increasing the number of times the sound cover 26 is knocked, thus achieving the effect of multiple alarms.

[0039] like Figures 2 to 4 As shown, a connecting shaft 25 is rotatably connected to the top of the positioning rod 18. The bottom of the connecting shaft 25 is fixedly connected to the top of the fourth gear 21. The bottom of the sound cover 26 is fixedly connected to the top of the positioning rod 18. Clamping plates 22 are symmetrically fixedly connected on both sides of the connecting shaft 25. A limiting post 24 is fixedly connected inside the clamping plate 22. A striking ring 23 is sleeved on the outside of the limiting post 24. The striking ring 23 is located in the middle of the clamping plate 22, and the inner diameter of the striking ring 23 is larger than the diameter of the limiting post 24. When the clamping plate 22 rotates with the striking ring 23, the outer side of the striking ring 23 contacts the inner wall of the sound cover 26 through centrifugal force.

[0040] With the set knocking ring 23 and clamping plate 22, when the fourth gear 21 rotates, it will drive the connecting shaft 25 to rotate. At this time, the clamping plate 22 will drive the knocking ring 23 to rotate. Since the inner diameter of the knocking ring 23 is larger than the outer diameter of the limiting post 24, the centrifugal force causes the outer side of the knocking ring 23 to contact the inner wall of the sound cover 26 when it rotates, thereby causing the sound cover 26 to make a sound, thus achieving the function of alarm.

[0041] like Figures 2 to 4 As shown, a torsion spring 16 is wound around the top of the positioning post 14, and a positioning block 17 is fixedly connected to the top of the fan-shaped plate 13. One end of the torsion spring 16 is fixedly connected to the inside of the positioning block 17, and the other end of the torsion spring 16 is fixedly connected to the side wall of the fixing box 12.

[0042] With the torsion spring 16 in place, when the sector plate 13 rotates, the positioning block 17 at the top of the sector plate 13 will tighten the torsion spring 16. When the lever 11 rotates past the outside of the alignment plate 15, the torsion spring 16 will automatically loosen and tighten, causing the sector plate 13 to rotate in the opposite direction. This will cause the sector plate 13 to drive the striking ring 23 to rotate and strike the sound cover 26 to produce a sound, thus achieving the effect of repeatedly striking the sound cover 26 to sound an alarm.

[0043] like Figure 1 and Figure 5As shown, the bottom of the first gear 9 is fixedly connected to the first pulley 27 through the shaft passing through the top of the vehicle body 1. The first pulley 27 is connected to the second pulley 28 through the belt drive on one side. The bottom of the second pulley 28 is fixedly connected to the rotating paddle 29 through the shaft. The two rotating paddles 29 are located at the top and one side of the driver's seat inside the vehicle body 1, respectively.

[0044] With the first pulley 27 and the second pulley 28 in place, when the first gear 9 rotates, it will cause the first pulley 27 to rotate as well. At this time, the second pulley 28 will rotate via the belt, and the rotating paddle 29 will also rotate. The driver can then visually observe the obstruction ahead through the rotating paddle 29 overhead.

[0045] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
