Description

Technical Field

[0001] This application relates to the field of semi-trailer technology, and in particular to a collide protection structure for a shed-type semi-trailer. Background Technology

[0002] With the rapid development of domestic trade, the large-scale transportation of goods has also grown and expanded. Semi-trailer transportation plays an important role in land transportation. Therefore, multi-faceted protective measures for semi-trailers are also extremely important. When loading and unloading goods, warehouse-type semi-trailers need to reverse to the designated area in a relatively narrow space, which often leads to collisions and damage to the vehicle body.

[0003] A related anti-collision structure for a semi-trailer includes a fixed component and an extension component. The fixed component is fixed to the bumper at the rear of the semi-trailer by means of bolting or other methods. The extension component extends outward from the fixed component. When the semi-trailer is reversing and a collision occurs, it will first collide with the extension component, reducing damage to the vehicle body.

[0004] However, the existing canopy-type semi-trailer anti-collision structure can only reduce the damage to the semi-trailer in a collision, but it does not warn the driver in time to stop reversing before a collision occurs. Utility Model Content

[0005] In order to reduce the problem that the anti-collision structure of the canopy semi-trailer cannot warn the driver, this application provides an anti-collision structure for the canopy semi-trailer.

[0006] This application provides a collision protection structure for a semi-trailer with a canopy, employing the following technical solution: A canopy-type semi-trailer anti-collision structure includes: Fixed support, which is vertically fixed to the rear bumper of the semi-trailer; A connecting rod is fixedly installed at the lower end of a fixed support, and a horizontal sliding groove is provided inside the connecting rod. The transmission component has one end rotatably connected to the fixed support, and the other end slidably disposed in the slide groove. The alarm is fixedly installed inside the slide.

[0007] By adopting the above technical solution, the fixed support installed on the rear bumper of the semi-trailer can contact the object being impacted during a collision, reducing the damage to the semi-trailer body. At the same time, the fixed support can also provide installation space for the anti-collision structure. The connecting rod is fixedly set at the bottom of the fixed support, providing installation space for the transmission component. The pressure generated when the rear of the semi-trailer contacts the object being impacted can push the transmission component to slide on the fixed support, causing the transmission component to activate the alarm and achieve the purpose of warning the driver.

[0008] Optionally, the transmission components include: A rotating shaft is rotatably mounted around a fixed support. A transmission rod, one end of which is rotatably connected to a rotating shaft; The slider is slidably positioned within the groove. The telescopic rod has one end rotatably connected to the slider. The connecting plate has one end rotatably connected to the transmission rod and the other end rotatably connected to the telescopic rod.

[0009] By adopting the above technical solution, one end of the rotating shaft is rotatably connected to the fixed support, and the other end of the rotating shaft is rotatably connected to the transmission rod, so that the transmission rod can rotate around the fixed support. One end of the telescopic rod is rotatably connected to the slider, and the other end of the telescopic rod is rotatably connected to the connecting plate. When the connecting plate is subjected to pressure and moves closer to the connecting rod, the connecting plate drives the transmission rod to rotate around the rotational connection between the connecting rod and the rotating shaft. The connecting plate drives the telescopic rod to rotate around the rotational connection between the telescopic rod and the slider. When the distance between the connecting plate and the connecting rod is slightly greater than the length of the impact head, the slider slides to the end of the groove and contacts the alarm. The alarm is activated to warn the driver, thus achieving the purpose of the anti-collision structure to warn the driver.

[0010] Optionally, two sets of fixed supports, transmission components, and alarms are symmetrically arranged along the centerline of the connecting rod.

[0011] By adopting the above technical solution, the two sets of fixed supports, transmission components and alarms can enable the anti-collision structure to protect the two sides of the rear of the semi-trailer. When the two sides of the rear of the semi-trailer collide, the two sets of transmission components will activate the two sets of alarms respectively, so that when different positions are hit, the two sets of alarms will sound an alarm to warn the driver.

[0012] Optionally, an impact head is provided at the upper end of the fixed support.

[0013] By adopting the above technical solution, the impact head is designed so that when a semi-trailer is involved in a collision, the impact head can take the impact first, reducing the damage to the semi-trailer body.

[0014] Optionally, the alarm is a push-button alarm.

[0015] By adopting the above technical solution, the push-button alarm can cause the anti-collision structure to transmit pressure through the transmission component when it is hit, thereby alerting the driver.

[0016] Optionally, the longest distance between the pivot and the impact head is shorter than the length of the connecting rod.

[0017] By adopting the above technical solution, the connecting rod can rotate around the axis of the rotating shaft and move closer to the semi-trailer bumper, thus avoiding a collision between the connecting plate at one end of the transmission rod and the fixed support.

[0018] Optionally, the diameter of the slider is larger than the diameter of the alarm switch.

[0019] By adopting the above technical solution, the diameter of the slider is larger than that of the alarm switch, which makes the contact between the slider and the alarm closer. When the slider is close to the alarm, it can directly touch the alarm switch, thus improving the accuracy of the slider triggering the alarm.

[0020] Optionally, a protective pad is fixedly installed on the connecting plate, and the protective pad is made of rubber.

[0021] By adopting the above technical solution, when the anti-collision structure is impacted, the protective pad on the connecting plate will first contact the impacted object, thereby reducing the collision damage caused by the anti-collision structure to the impacted object.

[0022] Optionally, the telescopic rod can be a two-way spring telescopic rod.

[0023] By adopting the above technical solution, the telescopic rod is a two-way spring telescopic rod, which can shorten in both directions under greater pressure. When the semi-trailer and the object to be impacted continue to approach after the alarm is sounded, the telescopic rod on the connecting plate is shortened by pressure. When the distance between the connecting plate and the connecting rod is shortened to less than the length of the impact head, the impact head will first contact the object to be impacted, reducing the damage to the semi-trailer body from the collision.

[0024] Optionally, the fixed support is made of I-beams.

[0025] By adopting the above technical solution, the fixed support can be made of I-beams, which can improve the strength of the fixed support and reduce the manufacturing cost of the fixed support.

[0026] In summary, the embodiments of the present invention provide a canopy-type semi-trailer anti-collision structure, which includes at least one of the following beneficial technical effects: 1. The fixed support is installed on the rear bumper of the semi-trailer. It can contact the object being hit in the event of a collision, reducing the damage to the semi-trailer body. At the same time, the fixed support can also provide installation space for the anti-collision structure. The connecting rod is fixedly set at the bottom of the fixed support, providing installation space for the transmission component. The pressure generated when the rear of the semi-trailer contacts other objects can push the transmission component to slide on the fixed support, so that the transmission component can activate the alarm and achieve the purpose of warning the driver.

[0027] 2. Two sets of fixed supports, transmission components and alarms enable the anti-collision structure to protect both sides of the rear of the semi-trailer. When the rear sides of the semi-trailer collide, the two sets of transmission components will activate the two sets of alarms respectively, so that when different positions are hit, the two sets of alarms will sound an alarm to warn the driver.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] Combination Figure 1 , Figure 2 and Figure 3 This application discloses a canopy-type semi-trailer anti-collision structure, including: a fixed support 11, a connecting rod 12, a transmission assembly 2, and an alarm 13. The fixed support 11 is vertically fixed on the rear bumper of the semi-trailer. The connecting rod 12 is fixedly installed at the lower end of the fixed support 11. A sliding groove 14 is horizontally provided inside the connecting rod 12. One end of the transmission assembly 2 is rotatably connected to the fixed support 11, and the other end of the transmission assembly 2 is slidably installed in the sliding groove 14. The alarm 13 is fixedly installed in the sliding groove 14.

[0032] In this embodiment, the fixed support 11 is rectangular and made of I-beams. The use of I-beams increases the strength of the fixed support 11 and reduces its manufacturing cost. The fixed support 11 can be bolted or welded to the semi-trailer's rear bumper; this embodiment does not specify a particular connection. An impact head 15, also rectangular, is provided at the upper end of the fixed support 11. This impact head 15 can withstand the impact during a collision, reducing damage to the semi-trailer's body. The connecting rod 12 is cylindrical and fixedly connected to the lower end of the fixed support 11. The connection between the connecting rod 12 and the fixed support 11 can be bolted or welded; this embodiment does not specify a particular connection. One end of the transmission assembly 2 is rotatably connected to the fixed support 11. The transmission component 2 can rotate around the fixed support 11 and approach the semi-trailer bumper, allowing the transmission component 2 to enter a folded state. When the transmission component 2 is subjected to pressure from the impacted object, it will slide within the slide groove 14. The alarm 13 is cylindrical and is a push-button type. The transmission component 2 slides within the slide groove 14 and abuts against the alarm 13. The transmission component 2 transmits pressure, causing the alarm 13 to activate and sound an alarm to warn the driver. The fixed support 11, transmission component 2, and alarm 13 are symmetrically arranged in two sets along the centerline of the connecting rod 12. The two sets of fixed supports 11 allow the anti-collision structure to protect both sides of the rear of the semi-trailer. When the rear sides of the semi-trailer are impacted, the two sets of transmission components 2 will activate the two sets of alarms 13 respectively, so that when different positions are impacted, the two sets of alarms 13 will sound an alarm to warn the driver.

[0033] In practical use, before the driver reverses the semi-trailer in a relatively narrow area, the driver rotates the transmission component 2 around the pivot 21, turning the transmission component 2 from a vertical state to a horizontal state, thus unfolding the transmission component 2 from a folded state. When the driver reverses the semi-trailer in a relatively narrow area, when the anti-collision structure comes into contact with the object being impacted, the object being impacted exerts pressure on the anti-collision structure, and the transmission component 2 is subjected to force, causing the transmission component 2 to slide on the connecting rod 12. The transmission component 2 slides until it comes into contact with the alarm 13 and activates the switch of the alarm 13, causing the alarm 13 to sound an alarm to warn the driver.

[0034] Combination Figure 3 In one specific embodiment, the transmission assembly 2 includes: a rotating shaft 21, a transmission rod 22, a slider 23, a telescopic rod 24, and a connecting plate 25. The rotating shaft 21 is rotatably disposed around the fixed support 11. One end of the transmission rod 22 is rotatably connected to the rotating shaft 21. The slider 23 is slidably disposed in the slide groove 14. One end of the telescopic rod 24 is rotatably connected to the slider 23. One end of the connecting plate 25 is rotatably connected to the transmission rod 22, and the other end of the connecting plate 25 is rotatably connected to the telescopic rod 24.

[0035] In this embodiment, the rotating shaft 21 is cylindrical, and the diameter of the end of the rotating shaft 21 near the fixed support 11 is smaller than the diameter of the rotatable connection between the rotating shaft 21 and the transmission rod 22. The connecting rod 12 is cuboid, and its length is shorter than the longest distance between the rotating shaft 21 and the impact head 15. The connecting rod 12 can rotate around the axis of the rotating shaft 21 and fold up towards the semi-trailer bumper, thus preventing the connecting plate 25 at one end of the transmission rod 22 from colliding with the fixed support 11. The slider 23... The device is cylindrical in shape. The diameter of the slider 23 is the same as the diameter of the slide groove 14. The diameter of the slider 23 is larger than the switch diameter of the alarm 13. The telescopic rod 24 is rectangular in shape and is a two-way spring telescopic rod. The connecting plate 25 is rectangular in shape and has a protective pad 16 fixed on it. The protective pad 16 is rectangular in shape and is made of rubber. When the semi-trailer comes into contact with the object being impacted, the protective pad 16 will make contact with the object being impacted first, reducing the damage to the object being impacted.

[0036] In practical use, as the semi-trailer gradually reverses, the protective pad 16 contacts the object being impacted. As the distance between the semi-trailer and the object decreases, the connecting plate 25 is pressurized and gradually approaches the connecting rod 12. The pressure on the connecting plate 25 drives the transmission rod 22 to rotate around the rotational connection between the transmission rod 22 and the rotating shaft 21. The pressure on the connecting plate 25 drives the telescopic rod 24 to rotate around the rotational connection between the telescopic rod 24 and the slider 23. The rotation of the telescopic rod 24 drives the slider 23 to slide towards the alarm 13. When the distance between the connecting plate 25 and the connecting rod 12 approaches the length of the impact head 15, that is, when the impact head 15... When the slider 23 is about to come into contact with the object to be impacted, it comes into contact with the alarm 13 and activates the alarm 13, causing the alarm 13 to sound an alarm to warn the driver. When the driver continues to reverse, the slider 23 is blocked by the alarm 13 and cannot continue to slide. The connecting plate 25 continues to be subjected to the pressure of the object to be impacted. The pressure transmitted by the connecting plate 25 causes the telescopic rod 24 to contract under pressure. The connecting plate 25 continues to approach the connecting rod 12. When the distance between the connecting plate 25 and the connecting rod 12 is less than the length of the impact head 15, the impact head 15 comes into contact with the object to be impacted, thereby reducing the damage to the semi-trailer body caused by the collision.

[0037] The implementation principle of this application is as follows: When the driver operates the semi-trailer with a canopy to reverse in a relatively narrow area, the driver unfolds the transmission assembly 2 from the folded state, causing the transmission assembly 2 to rotate from the vertical state to the horizontal state. When the driver reverses, when the anti-collision structure comes into contact with the object being impacted, the object being impacted applies pressure to the connecting plate 25, causing the transmission rod 22 to rotate around the axis of the rotating shaft 21. The object being impacted applies pressure to the connecting plate 25, causing the telescopic rod 24 to rotate around the axis of the slider 23. The telescopic rod 24 rotates and transmits pressure, causing the slider 23 to slide along the axis of the slide groove 14 towards the alarm 13. When the object being impacted is about to contact the impact head 15, the slider 23 abuts against the alarm 13 and activates the switch of the alarm 13, causing the alarm 13 to sound an alarm to warn the driver. When the driver continues to reverse, the telescopic rod 24 is compressed and shortens, causing the connecting plate 25 to continue to move closer to the connecting rod 12. The object being impacted abuts against the impact head 15, and the impact head 15 collides with the object being impacted, reducing the damage to the semi-trailer body.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
