Abstract
Description
Technical Field
[0001] This utility model relates to the field of chassis vehicle technology, and in particular to a load-bearing protection mechanism and a low center of gravity chassis. Background Technology
[0002] In the field of industrial automation, autonomous mobile robot (AMR) chassis, as a core load-bearing component, are widely used in scenarios such as power plants and warehousing logistics, especially to meet the mobility needs of large lifting equipment. Currently, conventional AMR chassis designs mainly adopt the following technical solutions.
[0003] The integral load-bearing base plate with reinforced ribs has a large overall weight and high material cost. Moreover, it requires disassembling large components from above during maintenance, which is inconvenient. Although the layered installation platform can achieve functional zoning, it increases the height of the chassis, causing the center of gravity to shift upward and reducing stability. Furthermore, it requires disassembly layer by layer during maintenance, which is inefficient. Some chassis thick sheet metal or reinforced rib designs do not reasonably distinguish between load-bearing and non-load-bearing areas, resulting in material waste and poor adaptability to confined spaces.
[0004] Therefore, there is a need for a load-bearing protection mechanism and a low-center-of-gravity chassis that can concentrate the main weight in the lower part, adapt to flexible movement and hoisting scenarios, achieve high load-bearing capacity in a space with minimal thickness, and only require the removal of corresponding modules during maintenance without the need for overall disassembly, thereby effectively improving work efficiency to meet the needs of the current environment. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Given that the integral load-bearing base plate reinforced structure has problems such as large overall weight, high material cost, inconvenience in operation due to the need to disassemble large components from above during maintenance, reduced stability, and the lack of reasonable differentiation between load-bearing and non-load-bearing areas in the design of thick sheet metal or reinforced ribs, resulting in material waste and poor adaptability to confined spaces.
[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a locking component, including a positioning frame and a limiting bolt inserted into one side of the positioning frame;
[0008] The adjustment assembly includes a positioning element installed at one end of the positioning frame, a lifting assembly elastically connected to the bottom of the positioning element, and a telescopic sleeve disposed on the inner wall of the lifting assembly.
[0009] As a preferred embodiment of the load-bearing protection mechanism described in this utility model, the accommodating component includes a tray for receiving the frame and chassis components;
[0010] The support assembly includes a support frame connected to a tray at one end, a load-bearing frame fixed to the other end of the support frame, and an extension frame connected to one end of the load-bearing frame.
[0011] As a preferred embodiment of the load-bearing protection mechanism described in this utility model, wherein:
[0012] The number of load-bearing frames should be greater than one;
[0013] The load-bearing frame is fixedly fitted with mounting slots, and the top protection assembly is installed inside the mounting slots.
[0014] As a preferred embodiment of the load-bearing protection mechanism described in this utility model, wherein:
[0015] Limiting protrusions are provided around the bottom of the tray;
[0016] The two ends of the extended skeleton extend beyond the load-bearing skeleton, and the extended ends of the extended skeleton are flush with the limiting protrusions.
[0017] As a preferred embodiment of the load-bearing protection mechanism described in this utility model, wherein:
[0018] The outer frame is fixedly connected to the other side of the extended frame;
[0019] The outer skeleton and the extended skeleton surround each other to form a cavity.
[0020] As a preferred embodiment of the load-bearing protection mechanism described in this utility model, wherein:
[0021] The sidewall of the extended skeleton is fixedly connected to a reinforcing member, which is located within the receiving cavity;
[0022] One end of the reinforcing member is connected to the extended skeleton, and the other end is connected to the outer skeleton.
[0023] As a preferred embodiment of the load-bearing protection mechanism described in this utility model, wherein:
[0024] A buffer component is fixedly installed at the top of the extended frame, with diagonal braces extending from both ends of the buffer component;
[0025] The other end of the diagonal brace is attached to the side wall of the extended skeleton.
[0026] As a preferred embodiment of the load-bearing protection mechanism described in this utility model, wherein:
[0027] A fixing port is provided on the outer side of the extended frame;
[0028] The fixing port connects to the outer wall protection assembly, which fits into the extension frame, the load-bearing frame, and the outer wall of the outer frame.
[0029] The beneficial effects of the load-bearing protection mechanism of this utility model are as follows: using I-beams as the core frame, high load-bearing capacity is achieved within a minimum thickness space, replacing the traditional thick base plate or reinforcing rib structure. Thin sheet metal is used to fix electrical components around the perimeter and top, serving only the functions of installation and protection, significantly reducing weight.
[0030] While existing layered installation platforms can achieve functional zoning, they increase chassis height, leading to an upward shift in the center of gravity and reduced stability. This makes them unsuitable for the movement requirements of large hoisting equipment and poorly adapted to working environments such as power plant logistics that require frequent relocation.
[0031] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a running component, including a control panel fixedly mounted on a tray, a movable assembly installed in a receiving cavity, and a receiving end located on one side of the control panel.
[0032] As a preferred embodiment of the low center of gravity chassis of this utility model, the other end of the control panel is located outside the outer wall protection assembly, and a warning device is embedded on the surface of the outer wall protection assembly.
[0033] The drag link and emergency stop end are fixedly connected to the outer wall protection assembly.
[0034] As a preferred embodiment of the low center of gravity chassis described in this utility model, wherein:
[0035] The moving assembly includes a stabilizing element that is fixedly connected to accommodate the cavity;
[0036] A drive motor is fixedly connected to the side wall of the stabilizer, and a moving part is mounted on the surface of the stabilizer.
[0037] The advantages of the low center of gravity chassis of this utility model are: electrical components are integrated in sections on the inside of thin sheet metal, and only the corresponding modules need to be removed during maintenance, without the need for overall disassembly, thus improving efficiency.

[0047] Example 1
[0048] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a load-bearing protection mechanism.
[0049] The housing component 1 is used to house the core structure of the entire load-bearing and protection mechanism. The housing component 1 includes a tray 11, on which a frame for bearing the load and other electronic components required for the movement of the chassis are placed.
[0050] Support component 2 serves as the core support and load-bearing element, forming the overall framework. Support frame 21 is fixedly connected to tray 11, providing a stable and secure installation for the overall framework. A load-bearing frame 22 is fixedly connected to the top of support frame 21, forming the core of the overall framework within support component 2.
[0051] The support frame 22 is located at the center of the tray 11, and extends at both ends for additional fixed connection of the extension frame 23. The extension frame 23 is used to expand new installation space and facilitate additional functional expansion of the chassis.
[0052] The combination of the load-bearing frame 22 and the extended frame 23 improves the load-bearing capacity within a minimal thickness space. Compared with existing technologies, the structure has a stronger load-bearing capacity and effectively saves space. The number of load-bearing frames 22 is no less than one, which not only improves strength and support but also leaves ample installation space for subsequent sheet metal protection.
[0053] Example 2
[0054] Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0055] In this design, the number of load-bearing frames 22 is set to more than one, specifically three, but four to five frames can also be selected to meet the actual needs of the chassis. Gaps exist between the load-bearing frames 22 to form corresponding mounting slots 221, which are used to install the top protection assembly 2211.
[0056] The top protection assembly 2211 is made of thin sheet metal, is not subjected to stress, is lightweight, and can be fixed in place using common clips and bolts. The top protection assembly 2211 provides physical protection from the vertical direction, but the core stress and load-bearing parts are handled by the support component 2.
[0057] The bottom of the tray 11 is surrounded by a limiting protrusion 111. The limiting protrusion 111 is used to cooperate with the sheet metal structure of the side wall. The two ends of the extension frame 23 extend beyond the load-bearing frame 22 and are flush with the limiting protrusion 111. This ensures that when it cooperates with the sheet metal structure of the side wall, it is also limited by the limiting protrusion 111, thus ensuring that the installation of the sheet metal structure of the side wall is stable, firm, and tightly fitted.
[0058] An outer frame 24 is fixedly connected and installed on the other side of the extension frame 23. The outer frame 24 surrounds the two ends of the extension frame 23 to form a receiving cavity 241. The receiving cavity 241 is used to expand and install additional electrical components required for the entire chassis. The corresponding components can be placed in the receiving cavity 241, which can be effectively protected while making effective use of the remaining space.
[0059] The side wall of the extended frame 23 is fixedly connected to the reinforcing member 231. The reinforcing member 231 itself is located in the receiving cavity 241, and the other end is connected to the outer frame 24. This divides the receiving cavity 241 into two additional blocks, while also providing strength and support enhancement. It can also serve as a support for the installation of components in the receiving cavity 241. Components and reinforcing member 231 can be connected as needed.
[0060] A buffer component 232 is fixedly installed on the top of the extended frame 23. The buffer component 232 can effectively support and buffer, preventing the force from exceeding the support component 2 and acting on the relatively thin top protection assembly 2211, thereby improving the service life of the top protection assembly 2211. Diagonal braces 2321 are extended from both ends of the buffer component 232. The other end of the diagonal brace 2321 can fit against the side wall of the extended frame 23, improving the force-bearing effect.
[0061] The outer side of the extended frame 23 is provided with a fixing port 233. There is more than one fixing port 233. The ports are symmetrically arranged according to the structural dimensions of the entire chassis. Through the fixing port 233, the outer wall protection assembly 2331 can be fixedly installed on the outer side of the extended frame 23. The outer wall protection assembly 2331 and the extended frame 23, the load-bearing frame 22 and the outer wall of the outer frame 24 are attached to each other. It is equivalent to setting up a whole set of thin side sheet metal around the entire chassis, which provides effective side protection and prevents the internal components of the chassis from being completely exposed.
[0062] Example 3
[0063] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on any of the above embodiments and adds a low center of gravity chassis.
[0064] The operating component 3 assists operators in the actual operation of the chassis, improving convenience. A control panel 31 is installed on the tray 11, with the other end of the control panel 31 located outside the outer wall protection assembly 2331, allowing for direct control of additional options.
[0065] On one side of the control panel 31, a receiver 33 is also provided on the tray 11, which serves to receive and transmit signals. An alarm 34 is embedded in the surface of the outer wall protection assembly 2331. The tow piece 35 and the emergency stop end 36 are fixedly connected to the outer wall protection assembly 2331. The tow piece 35 can be configured as a hook shape to facilitate towing the chassis for operation using an additional transport vehicle. The emergency stop end 36 is equipped with an emergency stop button for quick stopping in emergencies.
[0066] The movable assembly 32 is disposed within the receiving cavity 241, providing the core moving function. The stabilizing component 321 is fixedly connected to the receiving cavity 241, ensuring the overall installation of the movable assembly 32 is secure. A movable component 323 is mounted on the surface of the stabilizing component 321, and the movable component 323 is rotatably connected to the stabilizing component 321; in this application, a wheel is selected as the movable component 323.
[0067] The side wall of the stabilizer 321 is fixedly connected to the drive motor 322, which is directly used to drive the moving component 323 to rotate and drive the chassis to move.
