Description

Technical Field

[0001] This utility model relates to the field of heavy-duty omnidirectional AGV robot technology, and in particular to a housing mechanism for a heavy-duty omnidirectional AGV robot. Background Technology

[0002] The body shell of a heavy-duty omnidirectional AGV robot serves a dual purpose: protecting the internal core functional components and providing aesthetic decoration. In applications requiring high lifting height, the height of the internal lifting mechanism needs to be increased to enhance the AGV's lifting capacity (typically, the lifting height of the lifting mechanism is consistent with its own height). Simultaneously, to isolate the lifting mechanism from external environmental interference, a taller shell is needed to create full-enclosed protection. Directly increasing the height of the body shell would encroach on the installation space of functional components such as radar, and the equipment would be exceptionally large, occupying a significant amount of space. Therefore, the industry commonly adopts a solution of superimposing a protective shell for the lifting mechanism onto the body shell. The top of the protective shell features a lifting plate that rises and falls with the lifting mechanism, and a telescopic bellows cover is installed between the two.

[0003] However, this structure has obvious defects: the weight of the protective cover of the lifting mechanism is entirely borne by the vehicle body shell. After long-term use, the vehicle body shell is prone to deformation due to continuous stress. This will not only damage other functional components in the shell cavity, but also cause the protective cover to tilt as the shell deforms, which will disrupt the force balance and operational stability of the lifting mechanism and seriously affect the normal operation of the AGV.

[0004] Therefore, there is an urgent need for a new type of housing structure that can avoid the load-bearing capacity of the vehicle body shell and use higher strength components to stably support the protective shell of the lifting mechanism, so as to solve the dual problems of vehicle body deformation and unstable operation of the lifting mechanism in the traditional solution. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of the prior art and provide a housing mechanism for a heavy-duty omnidirectional AGV robot. This addresses the technical issues in traditional AGVs where the vehicle body housing, bearing the protective casing of the lifting mechanism, causes deformation and crushing of components, and the tilting of the protective casing affects the operation of the lifting mechanism. The chassis directly supports the protective casing of the lifting mechanism, ensuring its stable operation.

[0006] The above objectives are achieved through the following technical solutions: A housing mechanism for a heavy-duty omnidirectional AGV robot includes a body shell and a chassis that can be connected to each other to form an installation cavity. The top of the body shell has a shell through slot that matches the shape of the protective shell of the lifting mechanism and allows it to pass through. The surface of the chassis is provided with a shell support assembly. The bottom of the protective shell of the lifting mechanism passes through the shell through slot and is connected to the top of the shell support assembly.

[0007] Furthermore, the top of the housing support assembly does not extend beyond the housing through slot, and there is no gap between the top of the fuselage protective shell and the bottom of the lifting mechanism protective shell on the horizontal plane.

[0008] Furthermore, the housing support assembly includes at least two sets of housing columns symmetrically arranged on the surface of the chassis. Each housing column is provided with a right-angle support block at its top. Each right-angle support block is provided with a housing support ring that matches the bottom shape of the lifting mechanism protective housing. A housing stop bar that can partially limit the outer side of the lifting mechanism protective housing is provided on the outside of the housing support ring.

[0009] Furthermore, the housing support ring and the housing baffle are perpendicular to each other and are integrally formed.

[0010] Furthermore, a screw hole is provided on the bottom edge of the right-angle support block, and a waist-shaped groove of the support ring matching the screw hole is provided on the sleeve support ring. The two are connected by screws.

[0011] Furthermore, the bottom of the lifting mechanism protective housing is provided with an inner right-angle flange, which can abut against the surface of the housing support ring.

[0012] Furthermore, the housing support ring is provided with a plurality of support ring screw holes, and the bottom of the lifting mechanism protective housing is provided with a number of outwardly extending screw feet corresponding to the number of support ring screw holes, and the screw feet are provided with foot screw holes; the foot screw holes and the support ring screw holes are connected by screws.

[0013] Furthermore, the inner wall of the protective sleeve of the lifting mechanism is provided with annular ribs.

[0014] Furthermore, both the lifting mechanism protective housing and the housing bracket assembly are made of metal.

[0015] Furthermore, the metal material is stainless steel or aluminum alloy.

[0016] This utility model provides a housing mechanism for a heavy-duty omnidirectional AGV robot. The protective housing of the lifting mechanism is directly supported by a housing bracket assembly on the chassis, preventing the vehicle body from deforming under stress and protecting internal functional components from compression. Furthermore, the stable support structure prevents the protective housing from tilting, ensuring stable operation of the lifting mechanism. The compact and seamless structure, along with the metal material and annular ribs, enhances durability. Specific beneficial effects are as follows: 1. Direct chassis support to avoid vehicle body deformation: The protective cover of the lifting mechanism is directly supported by the cover bracket assembly on the chassis, without the need for the vehicle body shell to bear the load. This prevents the vehicle body shell from deforming under pressure and squeezing the internal functional components, thus extending the service life of the equipment.

[0017] 2. Stable support to ensure the operation of the lifting mechanism: The symmetrical design and multi-part connection structure of the housing bracket assembly ensure the stable installation of the lifting mechanism protective housing, prevent tilting, and ensure the stable operation of the lifting mechanism.

[0018] 3. Compact structure and seamless connection: The top of the housing support assembly does not protrude from the housing through slot, and there is no gap between the bottom of the body protective housing and the lifting mechanism protective housing, which ensures both a compact structure and prevents foreign objects from entering.

[0019] 4. High strength and good durability: The protective housing and housing support assembly of the lifting mechanism are made of metal, and the inner wall of the protective housing is equipped with ring ribs to enhance the overall strength and adapt to the complex working conditions of heavy-duty AGVs.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] like Figs. 1-3 As shown, this solution provides a housing mechanism for a heavy-duty omnidirectional AGV robot, including the following structure: Body housing 1: Body housing 1 is connected to chassis 2 to form an installation cavity. The top is provided with a housing through groove 101 that matches the shape of the lifting mechanism protective housing 3, allowing the lifting mechanism protective housing 3 to pass through.

[0024] Chassis 2: A housing bracket assembly 4 is provided on the surface of chassis 2 to support the protective housing 3 of the lifting mechanism.

[0025] Lifting mechanism protective housing 3: The bottom of the lifting mechanism protective housing 3 passes through the housing through groove 101 and is connected to the top of the housing support assembly 4. Its inner wall is provided with annular ribs 301 to increase longitudinal strength, and the bottom is provided with an inner right-angle flange 303, screw feet 304 and foot screw holes 302. The material is stainless steel or aluminum alloy and other metals.

[0026] The housing support assembly 4 includes at least two symmetrically arranged housing columns 401, with a right-angle support block 402 at the top. The right-angle support block 402 has a housing support ring 403 that matches the bottom shape of the lifting mechanism protective housing 3, and a housing baffle 404 on its outer side. The housing support ring 403 and the housing baffle 404 are perpendicular and integrally formed. The right-angle support block 402 has a support block screw hole 405 on its bottom side, and the housing support ring 403 has a support ring waist-shaped groove 406. The two are screwed together. The housing support ring 403 has a support ring screw hole 407, which is connected to the support foot screw hole 302 of the lifting mechanism protective housing 3 by screws. The housing support assembly 4 is made of stainless steel or aluminum alloy, and its top does not extend beyond the housing through groove 101, ensuring a seamless horizontal connection between the top of the body housing 1 and the bottom of the lifting mechanism protective housing 3.

[0027] like Fig. 1 and Fig. 2 As shown, during assembly, first install the housing bracket assembly 4 on the surface of the chassis 2, ensuring that the housing columns 401 are symmetrically distributed. Then, align the bottom of the lifting mechanism protective housing 3 with the housing through groove 101 of the fuselage housing 1, so that it passes through the housing through groove 101. After that, the inner right-angle flange 303 at the bottom abuts against the surface of the housing support ring 403, and the support screw hole 302 of the screw foot 304 is aligned with the support ring screw hole 407 of the housing support ring 403, and is fixed by screwing. At the same time, the support block screw hole 405 of the right-angle support block 402 is aligned with the support ring waist groove 406 of the housing support ring 403, and is connected by screws. The housing stop strip 404 limits the outer side of the lifting mechanism protective housing 3. Finally, connect the fuselage housing 1 and the chassis 2 to form an installation cavity, completing the assembly of the entire housing mechanism.

[0028] During use, the chassis 2 directly bears the weight of the lifting mechanism protective cover 3 through the cover bracket assembly 4, and the body cover 1 does not need to bear this load, thus avoiding vehicle body deformation; the symmetrical structure and multiple connection methods of the cover bracket assembly 4 ensure that the lifting mechanism protective cover 3 is installed stably and will not tilt, thus ensuring the stable operation of the lifting mechanism.

[0029] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
