The International Organization for Standardization (ISO / TC110) refers to them as industrial vehicles. They are commonly used for transporting large items in warehouses and are typically powered by internal combustion engines or batteries. The technical parameters of a forklift indicate its structural characteristics and working performance. Key technical parameters include: rated lifting capacity, load center distance, maximum lifting height, mast tilt angle, maximum travel speed, minimum turning radius, minimum ground clearance, wheelbase, and track width.

[0003] The existing forklift chassis have the following shortcomings: The chassis is a single unit, therefore it does not deform and thus lacks inherent shock absorption capabilities. Relying solely on shock absorbers between the chassis and the rotating shaft for vibration damping is insufficient. Utility Model Content

[0004] In view of the problems existing in the smooth operation of the existing electronic forklift chassis with shock absorption structure, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide a stable-running electronic forklift chassis with a shock-absorbing structure, solving the problem that existing forklift chassis are integral pieces, thus lacking inherent shock absorption capabilities due to the chassis itself not deforming. Relying solely on shock absorbers between the chassis and the rotating shaft results in inadequate shock absorption.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A smooth-running electronic forklift chassis with a shock-absorbing structure includes a chassis body. The chassis body includes a U-shaped main support frame. A rear bumper is welded to one end of the U-shaped main support frame, and a first reinforcing support beam is welded to the other end of the U-shaped main support frame. A front bumper is welded to the end of the first reinforcing support beam away from the U-shaped main support frame. The U-shaped main support frame is composed of a U-shaped bracket and a second reinforcing support beam. The second reinforcing support beam is hinged to the U-shaped bracket, and a shock-absorbing mechanism is provided between the second reinforcing support beam and the U-shaped bracket.

[0007] As a preferred embodiment of the electronic forklift chassis with shock absorption structure described in this utility model, the second reinforcing support beam has two beams, and the ends of the two second reinforcing support beams are welded with hinge seats. The two ends of the U-shaped bracket are respectively hinged to the two hinge seats through pins.

[0008] As a preferred embodiment of the electronic forklift chassis with shock-absorbing structure described in this utility model, wherein: the ends of the two second reinforcing support beams away from the U-shaped bracket are welded to the rear bumper; The ends of the two first reinforcing support beams furthest from the front bumper are welded to the U-shaped bracket.

[0009] As a preferred embodiment of the electronic forklift chassis with shock-absorbing structure described in this utility model, wherein: the bottom of both the second reinforcing support beam and the first reinforcing support beam are welded with roller support rods, and the roller support rods are used to install wheels.

[0010] As a preferred embodiment of the electronic forklift chassis with shock-absorbing structure described in this utility model, the shock-absorbing mechanism includes a first support plate welded to a second reinforcing support beam and a second hinge seat welded to a U-shaped bracket. A third hinge seat is welded to the first support plate, and a first shock absorber is hinged between the second hinge seat and the third hinge seat.

[0011] As a preferred embodiment of the electronic forklift chassis with shock-absorbing structure described in this utility model, wherein: the first support plate is welded to the bottom of the second reinforcing support beam, and the second hinge seat is welded to the bottom of the U-shaped bracket.

[0012] As a preferred embodiment of the electronic forklift chassis with shock-absorbing structure described in this utility model, the shock-absorbing mechanism further includes a second support plate welded to the bottom of the second reinforcing support beam, a fourth hinge seat welded to the second support plate, a hinge rod welded to the bottom of the U-shaped bracket, and a second shock absorber hinged together between the fourth hinge seat and the hinge rod.

[0013] As a preferred embodiment of the electronic forklift chassis with shock-absorbing structure described in this utility model, wherein: the first support plate is welded to the top of the second reinforcing support beam, and the second hinge seat is welded to the top of the U-shaped bracket.

[0014] Compared with existing technologies: The chassis is constructed by hinges between two parts, and a shock-absorbing mechanism is installed between these two parts.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example

[0018] This utility model provides a smooth-running electronic forklift chassis with a shock-absorbing structure. Please refer to [link / reference]. Figure 1-2 The chassis body includes a U-shaped main support frame 4. A rear bumper 1 is welded to one end of the U-shaped main support frame 4, and a first reinforcing support beam 3 is welded to the other end of the U-shaped main support frame 4. A front bumper 2 is welded to the end of the first reinforcing support beam 3 away from the U-shaped main support frame 4. The U-shaped main support frame 4 is composed of a U-shaped bracket 42 and a second reinforcing support beam 41. The second reinforcing support beam 41 is hinged to the U-shaped bracket 42, and a shock absorption mechanism is provided between the second reinforcing support beam 41 and the U-shaped bracket 42.

[0019] The second reinforcing support beam 41 has two beams, and the ends of the two second reinforcing support beams 41 are welded with hinge seats 411. The two ends of the U-shaped bracket 42 are respectively hinged to the two hinge seats 411 through pins.

[0020] The ends of the two second reinforcing support beams 41 away from the U-shaped bracket 42 are welded to the rear bumper 1; The ends of the two first reinforcing support beams 3 furthest from the front bumper 2 are welded to the U-shaped bracket 42.

[0021] Both the second reinforcing support beam 41 and the first reinforcing support beam 3 have roller support rods 8 welded to their bottoms. The roller support rods 8 are used to install wheels.

[0022] The shock absorption mechanism includes a first support plate 6 welded to the second reinforcing support beam 41 and a second hinge seat 421 welded to the U-shaped bracket 42. A third hinge seat 61 is welded to the first support plate 6. The second hinge seat 421 and the third hinge seat 61 are hinged together to a first shock absorber 7. Since the second reinforcing support beam 41 and the U-shaped bracket 42 can be bent, when the chassis is moving, the bending of the second reinforcing support beam 41 and the U-shaped bracket 42 stretches or contracts the first shock absorber 7, thereby using the shock absorber 7 to achieve the purpose of shock absorption.

[0023] The first support plate 6 is welded to the bottom of the second reinforcing support beam 41, and the second hinge seat 421 is welded to the bottom of the U-shaped bracket 42. At this time, the shock absorption mechanism is installed at the bottom of the chassis instead of the top, so it will not occupy additional space on the top of the chassis.

[0024] In practical use, when the rollers are installed at the bottom of the roller support rod 8, the second reinforcing support beam 41 and the U-shaped bracket 42 bend and stretch or contract the first shock absorber 7 when the chassis moves, thereby using the shock absorber 7 to achieve the purpose of shock absorption. Example

[0025] See attached document Figure 3 Unlike Embodiment 1, the shock absorption mechanism also includes a second support plate 9 welded to the bottom of the second reinforcing support beam 41. A fourth hinge seat 91 is welded to the second support plate 9. A hinge rod 11 is welded to the bottom of the U-shaped bracket 42. A second shock absorber 10 is hinged together between the fourth hinge seat 91 and the hinge rod 11.

[0026] In practical use, when the rollers are installed at the bottom of the roller support rod 8, when the chassis moves, the second reinforcing support beam 41 and the U-shaped bracket 42 bend to stretch or contract the first shock absorber 7 and the second shock absorber 10, thereby using the shock absorber 7 and the second shock absorber 10 to achieve the purpose of shock absorption and further enhance the vibration reduction effect. Example

[0027] See attached document Figure 4Unlike Embodiment 1, the first support plate 6 is welded to the top of the second reinforcing support beam 41, and the second hinge seat 421 is welded to the top of the U-shaped bracket 42. At this time, the vibration damping mechanism is installed on the top of the chassis, so the vibration damping mechanism will not come into contact with the ground or objects on the ground.

[0028] In practical use, when the rollers are installed at the bottom of the roller support rod 8, the second reinforcing support beam 41 and the U-shaped bracket 42 bend and stretch or contract the first shock absorber 7 when the chassis moves, thereby using the shock absorber 7 to achieve the purpose of shock absorption.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
