Description

Technical Field

[0001] The present invention belongs to the field of safety devices, and in particular relates to an anti-collision device used in the process of cargo transportation. Background Art

[0002] A truck is a commercial vehicle designed and equipped primarily for carrying goods. Goods are primarily transported through the cargo compartment inside the vehicle. At the same time, with the rapid development of the logistics industry in contemporary society, trucks have been used more and more frequently, thus providing convenience for the logistics industry.

[0003] In traditional truck cargo compartments, elastic drawstrings are often used to secure the transported goods.

[0004] However, during the driving process of the vehicle, the cargo will inevitably shift due to the vibration and bumps on the road, which will cause the cargo to collide with the inner wall of the cargo warehouse, causing damage to the cargo or scratches on the surface of the cargo warehouse.

[0005] The utility model patent with the authorization announcement date of March 18, 2022 and the authorization announcement number CN 216071966 U discloses a telescopic logistics conveyor anti-collision device, wherein the right sides of the front and back of the conveyor body are fixedly connected to fixed plates, and the bottom of the fixed plate close to the side is fixedly connected to a horizontal plate. By setting the right end of the buffer plate to move downward, the first spring is squeezed, the first spring is stressed, the buffer plate is buffered, and the goods are also buffered, reducing the damage rate of the goods. By setting the frame to drive the limit plate to move left, the limit plate stretches the second spring to avoid collision between the telescopic end of the conveyor body and the working personnel, avoiding injury to the personnel. By setting the above structure, it has the advantages of good anti-collision effect and buffering of goods, solving the problem that the existing telescopic conveyor has poor anti-collision effect and does not have the ability to buffer goods. However, this technical solution is only applicable to logistics conveyors (i.e., traditionally known belt conveyors), and does not involve the problem of anti-collision of goods during vehicle driving and the protection of the inner wall of the freight warehouse. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an anti-collision device for cargo transportation. The device employs a buffer mechanism to cushion impact forces through the movement of an elastic telescopic rod, while also compressing a buffer spring to form a secondary buffer. This multi-layer anti-collision buffering mode prevents cargo from damaging the inner wall of the cargo compartment, thereby protecting the inner wall of the vehicle's cargo compartment.

[0007] The technical solution of the present invention is to provide an anti-collision device during cargo transportation, including a buffer device, characterized in that:

[0008] The buffer device is arranged inside the cargo compartment and is used to buffer the impact force generated by the shaking of the cargo inside the cargo compartment;

[0009] The buffer device comprises:

[0010] An extrusion plate, the end of which is fixedly connected to an elastic telescopic rod;

[0011] A sliding rod, wherein both ends of the sliding rod are respectively connected to two groups of elastic telescopic rods, and a buffer spring is sleeved on the outer surface of the sliding rod.

[0012] Specifically, the outer surface of the slide rod is slidably connected to two groups of sliders, the two groups of sliders are elastically connected via a buffer spring, and the outer surface of the slider is hinged to a connecting rod.

[0013] Specifically, one end of the connecting rod away from the slider is hinged to the extrusion plate, and one end of the elastic telescopic rod away from the extrusion plate is fixedly connected to the freight bin.

[0014] Furthermore, metal shrapnel is fixedly connected to both sides of the inner surface of the freight warehouse, and a blocking device is provided at the lower end of the inner surface of the freight warehouse.

[0015] Specifically, the blocking device includes an arc rod, the side surface of the arc rod is slidably connected to the outer warehouse, the lower end of the inner surface of the outer warehouse is fixedly connected to a spring, the end of the spring away from the outer warehouse is fixedly connected to the arc rod, and the lower surface of the arc rod is fixedly connected to a limiting rod.

[0016] Furthermore, the outer surface of the outer bin is slidably connected to a slide rail, an upper end of the inner surface of the slide rail is provided with an independent groove, and one end of the limiting rod away from the arc rod contacts the groove inside the slide rail.

[0017] The technical solution of the present invention further provides an anti-collision method based on the above anti-collision device, which is characterized by:

[0018] When a freight vehicle travels on a bumpy road, the cargo inside the cargo compartment will shift to a certain extent, thereby generating an impact force on the extrusion plate. At this time, the extrusion plate will correspondingly press the elastic telescopic rod, causing it to contract, and the movement of the elastic telescopic rod will cushion the impact force.

[0019] At the same time, the movement of the extrusion plate will also drive the connecting rod to move;

[0020] At this time, the connecting rod will drive the sliders on both sides closer to each other, thereby squeezing the buffer spring to form a secondary buffer, thereby preventing the cargo from damaging the inner wall of the cargo compartment;

[0021] At the same time, before loading the cargo, adjust the position of the cambered rod according to the shape of the cargo. When the position of the cambered rod needs to be adjusted, press the cambered rod downward; at this time, the cambered rod drives the limit rod to move downward synchronously;

[0022] At this time, the limit rod will disengage from the groove inside the slide rail and then contact the limit of the outer warehouse, which will push the outer warehouse to move, thereby providing movement resistance according to the shape of the goods and reducing the probability of direct contact with the cargo warehouse.

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] 1. The anti-collision device described in this technical solution is provided with a buffer device. When a freight vehicle travels on a bumpy road, the cargo inside the freight compartment will be deflected due to the bumpy road, thereby generating an impact force on the extrusion plate. At this time, the extrusion plate will correspondingly compress the elastic telescopic rod to cause it to contract, and the impact force is buffered by the movement of the elastic telescopic rod. At the same time, the movement of the extrusion plate will also drive the connecting rod to move. At this time, the connecting rod will drive the sliders on both sides to move closer to each other, thereby squeezing the buffer spring to form a secondary buffer, thereby preventing the cargo from causing damage to the inner wall of the freight compartment;

[0025] 2. The anti-collision device is provided with a blocking device. Before the cargo is loaded, the position of the arc rod can be adjusted according to the shape of the cargo. When the position of the arc rod needs to be adjusted, it is necessary to press the arc rod downward. At this time, the arc rod will drive the limit rod to move downward synchronously. At this time, the limit rod will disengage from the groove inside the slide rail and then contact the limit of the outer warehouse. At this time, the outer warehouse can be pushed to move, thereby providing movement blocking according to the shape of the cargo and reducing the probability of its direct contact with the cargo warehouse.

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] The technical solution of the present invention provides an anti-collision device during cargo transportation, including a buffer device 2, which is arranged inside the cargo warehouse 1 and can buffer the impact force generated by the shaking of the cargo inside the cargo warehouse 1. The two sides of the inner surface of the cargo warehouse 1 are fixedly connected with the metal springs 4. Since the metal springs 4 are arranged in an arc shape, they will produce a certain deformation when impacted, thereby buffering the impact force. A blocking device 3 is provided at the lower end of the inner surface of the cargo warehouse 1.

[0032] Specifically, the buffer device 2 includes:

[0033] The extrusion plate 201 has an end fixedly connected to the elastic telescopic rod 204. The side of the extrusion plate 201 away from the elastic telescopic rod 204 is made of shock-absorbing rubber material, so that it can absorb and buffer the impact force when it is subjected to impact force.

[0034] The sliding rod 203 has two ends connected to the two sets of elastic telescopic rods 204 respectively, and the outer surface of the sliding rod 203 is sleeved with a buffer spring.

[0035] Specifically, the outer surface of the slide bar 203 is slidably connected to the two groups of sliders 205, and the two groups of sliders 205 are elastically connected by a buffer spring. Therefore, when the sliders 205 on both sides approach or move away from each other, the buffer spring can buffer the sliders 205 through its own elastic deformation. The outer surface of the slider 205 is hinged to the connecting rod 202, and the end of the connecting rod 202 away from the slider 205 is hinged to the extrusion plate 201. The connecting rod 202 is set at an angle, so when it is impacted, it can drive the sliders 205 on both sides to move toward each other, and the end of the elastic telescopic rod 204 away from the extrusion plate 201 is fixedly connected to the freight warehouse 1.

[0036] The anti-collision device in the present technical solution is provided with a buffer device 2. When the freight vehicle travels on a bumpy road, the goods inside the freight warehouse 1 will be offset to a certain extent due to the bumpy road surface, thereby generating an impact force on the extrusion plate 201. At this time, the extrusion plate 201 will correspondingly compress the elastic telescopic rod 204 to cause it to contract, and buffer the impact force through the movement of the elastic telescopic rod 204. At the same time, when the extrusion plate 201 moves, it will also drive the connecting rod 202 to move. At this time, the connecting rod 202 will drive the sliders 205 on both sides to approach each other, thereby squeezing the buffer spring to form a secondary buffer, thereby preventing the goods from causing damage to the inner wall of the freight warehouse 1.

[0037] Furthermore, the blocking device 3 includes a curved rod 301, the side surface of the curved rod 301 is slidably connected to the outer bin 304, the upper end of the curved rod 301 is set to a curved surface, so as to prevent the corners from causing damage to the surface of the cargo, and at the same time, the curved rod 301 is set to be a plastic column with a sponge pad wrapped on the outer surface, so that it can produce a certain deformation when impacted, the lower end of the inner surface of the outer bin 304 is fixedly connected to the spring 302, and the end of the spring 302 away from the outer bin 304 is fixed to the curved rod 301 The cambered rod 301 is connected to the outer wall of the outer chamber 304, so the spring 302 can always push the cambered rod 301 to rise when it is not subjected to external force. The lower surface of the cambered rod 301 is fixedly connected to the limiting rod 303, and the outer surface of the outer chamber 304 is slidably connected to the slide rail 305. The upper end of the inner surface of the slide rail 305 is provided with multiple sets of independent grooves, so the position of the outer chamber 304 can be limited by the contact between the grooves and the limiting rod 303, and the end of the limiting rod 303 away from the cambered rod 301 contacts the groove inside the slide rail 305.

[0038] Before loading the cargo, the position of the arc rod 301 can be adjusted according to the shape of the cargo. When the position of the arc rod 301 needs to be adjusted, the arc rod 301 needs to be pressed downward. At this time, the arc rod 301 will drive the limit rod 303 to move downward synchronously. At this time, the limit rod 303 will disengage from the groove inside the slide rail 305, and then contact the limit of the outer warehouse 304. At this time, the outer warehouse 304 can be pushed to move, thereby providing it with movement blocking according to the shape of the cargo, reducing the probability of it directly contacting the cargo warehouse 1.

[0039] In actual use, when the freight vehicle travels on a bumpy road, the goods inside the freight compartment 1 will be deflected due to the bumps of the road, thereby generating an impact force on the extrusion plate 201. At this time, the extrusion plate 201 will correspondingly press the elastic telescopic rod 204 to cause it to contract, and the movement of the elastic telescopic rod 204 will buffer the impact force. At the same time, when the extrusion plate 201 moves, it will also drive the connecting rod 202 to move. At this time, the connecting rod 202 will drive the sliders 205 on both sides to move closer to each other, thereby squeezing the buffer spring to form a secondary buffer, and then Prevent the cargo from causing damage to the inner wall of the freight warehouse 1; at the same time, the position of the arc rod 301 can be adjusted according to the shape of the cargo before loading. When the position of the arc rod 301 needs to be adjusted, it is necessary to press the arc rod 301 downward. At this time, the arc rod 301 will drive the limit rod 303 to move downward synchronously. At this time, the limit rod 303 will disengage from the groove inside the slide rail 305, and then contact the limit of the outer warehouse 304. At this time, the outer warehouse 304 can be pushed to move, thereby providing it with movement blocking according to the shape of the cargo, reducing the probability of it directly contacting the freight warehouse 1.

[0040] Since the present invention adopts multiple motion blocking modes for transporting goods, it can provide corresponding motion blocking according to the shape of the goods, reducing the probability of direct contact with the freight warehouse, thereby avoiding the problem of rigid collision between the goods and the inner wall of the freight warehouse, causing damage to the goods or scratches on the surface of the freight warehouse.

[0041] The present invention can be widely used in the field of design and manufacture of vehicle-mounted cargo transportation devices.
