Description

Technical Field

[0001] This utility model relates to the field of forklift anti-scratching technology, and in particular to a foldable elastic protective device for the side of a forklift to prevent scratches. Background Technology

[0002] Forklifts are industrial material handling vehicles, specifically wheeled vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods. Foldable forklifts are special equipment that uses a folding structure to compress space, primarily used for operations in confined spaces or for portable transport. An existing forklift with a collision protection mechanism for processing ton-sized containers (publication number: CN218320590U) uses a manual lever assisted by a hydraulic actuator to lift the forklift's front lifting platform. Its main drive wheel is equipped with a drive wheel assist assembly, and a push handle is provided on the rear wall of the side lifting slide. The forklift's protective measures include a rear protective mesh, side impact protection bars at the bottom, and protective rollers in the middle. However, relying solely on the rigid contact between the side impact protection bars at the bottom and the goods or walls provides insufficient protection. In the face of lateral collisions with large objects, this can easily exacerbate scratches and wear on the forklift, and due to the lack of corresponding warnings, operators often fail to notice the damage in time. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable forklift side anti-scratch elastic protection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A foldable forklift side scraping elastic protection device includes a vehicle body and a chassis. The outer side of the chassis is provided with a side protection plate. A groove is opened on the side of the chassis near the side protection plate. A slider is movably installed in the groove. A telescopic column is installed between the outer wall of the slider and the side protection plate. A spring is fixed between one side of the slider and the inner wall of the groove.

[0005] As a further embodiment of this utility model, the two ends of the telescopic column are respectively connected to the slider and the side protective plate through hinge seats, and the grooves are symmetrically distributed on the outer side of the base frame.

[0006] As a further embodiment of this utility model, a rubber pad is fixedly provided on the outer side wall of the side protective plate, and a warning light is installed on the vehicle body by fasteners.

[0007] As a further embodiment of this utility model, a buzzer is provided below the warning light, and a permanent magnet is embedded in the slider.

[0008] As a further embodiment of this utility model, a reed switch is embedded in the groove near the spring, and the reed switch is magnetically connected to the slider.

[0009] As a further embodiment of this utility model, a rubber strip is fixed to the inner side of the side protective plate, and the side protective plates are symmetrically distributed on the base frame.

[0010] Compared with the prior art, the present invention has the following beneficial effects: When the vehicle body is transporting goods, the grooves, sliders, springs, and telescopic columns not only disperse and absorb the impact force in multiple dimensions when the side guard plate is hit, but also effectively buffer the force of the collision by working with the rubber pads on the outer wall and the rubber strips on the inner wall of the side guard plate. This prevents the side of the vehicle body from scraping against the goods, which could cause damage to parts or goods. Furthermore, during the sliding of the slider, the permanent magnet on it works with the reed switch in the groove to trigger the warning light and buzzer on the vehicle body, providing timely warning of the collision. This allows operators to quickly be aware of the risk of scraping and adjust their operations in time, further reducing the occurrence of scraping incidents on the side of the vehicle body.

[0015] Reference Figures 1-4 A foldable forklift side scraping elastic protection device includes a vehicle body 1 and a chassis 2. A side protection plate 101 is provided on the outer side of the chassis 2. A groove 201 is provided on the side of the chassis 2 near the side protection plate 101. A slider 203 is movably provided in the groove 201. A telescopic column 103 is installed between the outer wall of the slider 203 and the side protection plate 101. A spring 104 is fixed between one side of the slider 203 and the inner wall of the groove 201.

[0016] The impact force is initially absorbed by the rubber pads 102 on the outer wall of the side guard plate 101. Then the force is transmitted to the telescopic column 103 that is hinged to it. The telescopic column 103 transmits the force to the slider 203 by its own extension and rotation around the hinge point of the slider 203, pushing the slider 203 to slide inward along the groove 201 corresponding to the base frame 2. At the same time, it compresses the spring 104 between the slider 203 and the inner wall of the groove 201. The elastic force of the two sets of springs 104 forms a reverse buffer to further reduce the force. As the slider 203 slides, the permanent magnet 106 embedded in it gradually approaches the reed switch 202 on one side of the groove 201. When the distance between the two enters the sensing range, the reed switch 202 triggers the circuit, causing the warning lights 3 symmetrically distributed on the vehicle body 1 to light up and the buzzer 4 to sound, issuing a collision warning to the operator. At the same time, the rubber strip 105 on the edge of the inner wall of the side guard plate 101 prevents the guard plate from having a hard collision with the vehicle body 1.

[0017] In this embodiment, the two ends of the telescopic column 103 are connected to the slider 203 and the side protection plate 101 through the hinge seat, and the grooves 201 are symmetrically distributed on the outside of the base frame 2.

[0018] When the permanent magnet 106 slides close to the reed switch 202 along with the slider 203, the two work together to trigger the circuit to make the warning light 3 light up and the buzzer 4 sound, transmitting a risk signal of scraping to the operator in a synchronized sound and light manner.

[0019] In this embodiment, a rubber pad 102 is fixedly provided on the outer side wall of the side guard plate 101, and a warning light 3 is installed on the vehicle body 1 by fasteners.

[0020] The rubber pad 102 is made of wear-resistant and elastic material, which can reduce friction when in direct contact with the goods and prevent scratches and damage between the goods and the side guard plate 101.

[0021] In this embodiment, a buzzer 4 is provided below the warning light 3, and a permanent magnet 106 is embedded in the slider 203.

[0022] The rubber strip 105 is made of elastic rubber and is used to avoid hard collisions between the side guard plate 101 and the vehicle body 1, thereby reducing collision noise and component wear.

[0023] In this embodiment, a reed switch 202 is embedded in the groove 201 on the side near the spring 104, and the reed switch 202 is magnetically connected to the slider 203.

[0024] The side guard plate 101 has an arc-shaped surface, which can better disperse the impact force and improve the anti-scratch effect.

[0025] In this embodiment, a rubber strip 105 is fixed to the inner side of the side protection plate 101, and the side protection plates 101 are symmetrically distributed on the base frame 2.

[0026] The reed switch 202 and the permanent magnet 106 are magnetically coupled through the magnetic field to induce a magnetic effect. The reed switch 202 is equivalent to a "switch" controlled by the magnetic field. When the permanent magnet 106 is close, its internal contacts close to connect the circuit, thereby triggering or turning off the warning light 3 and the buzzer 4, so as to achieve precise control of the collision warning.

[0027] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: During the handling of goods by the folding forklift, the side guard plate 101 first absorbs the impact force with the help of the rubber pad 102 on the outer wall, and then the force is transmitted to the telescopic column 103 hinged to it. The telescopic column 103 transmits the force to the slider 203 through its own extension and contraction and rotation around the hinge point of the slider 203, pushing the slider 203 to slide inward along the groove 201 corresponding to the base frame 2, while compressing the spring 104 between the slider 203 and the inner wall of the groove 201. The elastic force of the two sets of springs 104 forms a reverse buffer to further relieve the force, while the inner edge of the side guard plate 101... The rubber strip 105 prevents the protective plate from hard collision with the vehicle body 1. As the slider 203 slides, the embedded permanent magnet 106 gradually approaches the reed switch 202 on one side of the groove 201. When the distance between the two enters the sensing range, the reed switch 202 triggers the circuit, causing the warning lights 3 symmetrically distributed on the vehicle body 1 to light up and the buzzer 4 to sound, issuing a collision warning to the operator. When the collision force disappears, the restoring force of the spring 104 pushes the slider 203 to slide outward along the groove 201, and the permanent magnet 106 moves away from the reed switch 202. The circuit is disconnected, the warning device stops working, and the entire system returns to its initial state, waiting for the next collision protection response.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
