[0001] This utility model relates to the field of engineering machinery technology, specifically to outrigger mechanisms and engineering machinery. Background Technology

[0002] Construction projects require a large number of construction machines to complete various tasks. In some construction machinery, outriggers are used to support the machine's body to ensure stability, such as excavators, cranes, and concrete pump trucks. With the promotion of hybrid and pure electric technologies, the integration of battery packs in construction machinery is becoming increasingly diverse, but most are integrated into the chassis, turntable, or turret, or arranged separately, resulting in low utilization of space within the outriggers. Utility Model Content

[0003] In view of this, the present invention provides a leg mechanism and engineering machinery to solve the problem of low utilization rate of the internal space of the leg in the prior art.

[0004] In a first aspect, the present invention provides a leg support mechanism, comprising: a leg body having a cavity inside to form a receiving space; a battery structure disposed within the receiving space; and a telescopic support structure, the upper end of which is connected to the leg body, and the lower end of which is adapted to be close to or away from a predetermined support position.

[0005] Beneficial effects: The cavity inside the outrigger body serves as a storage space to house the battery structure, which in turn powers the entire vehicle, thus improving the space utilization of the outrigger body.

[0006] In one alternative embodiment, the telescopic support structure includes an electric cylinder, and the battery structure is electrically connected to the electric cylinder.

[0007] Beneficial effects: The electric cylinder provides telescopic support for the outrigger body, and the battery structure inside the outrigger body can power the electric cylinder, which facilitates the application of the electric cylinder and improves the working efficiency of the outrigger mechanism.

[0008] In one optional embodiment, the outrigger mechanism further includes a rotary drive structure, which is connected to the outrigger body via a transmission connection; the rotary drive structure includes a rotary motor, and the battery structure is electrically connected to the rotary motor.

[0009] Beneficial effects: The outrigger body is driven to rotate by a rotary motor, and the rotary motor can be powered by a battery structure inside the outrigger body, which facilitates the application of the rotary motor and improves the working efficiency of the outrigger mechanism.

[0010] In one optional embodiment, the leg body includes an upper side plate and a lower side plate that are spaced apart from each other in a vertical direction. The leg body also includes a reinforcing plate, the upper and lower sides of which are connected to the upper side plate and the lower side plate, respectively, to form at least two receiving spaces between the upper side plate and the lower side plate.

[0011] Beneficial effects: While ensuring the load-bearing capacity of the outrigger body, it can make full use of the various accommodating spaces within the outrigger body.

[0012] In one alternative embodiment, the reinforcing plate is provided as one or as several at intervals.

[0013] In one alternative embodiment, an opening is formed between the edge of the upper side plate and the edge of the lower side plate, and the leg body further includes a covering structure that is connected to the upper side plate and the lower side plate and covers the opening.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0027] According to an embodiment of the present invention, a support leg mechanism is provided, comprising: a support leg body 1, a battery structure 2, and a telescopic support structure 4. The support leg body 1 has a cavity to form a receiving space 11, and the battery structure 2 is disposed within the receiving space 11. The upper end of the telescopic support structure 4 is connected to the support leg body 1, and the lower end of the telescopic support structure 4 is adapted to approach or move away from a predetermined support position.

[0028] The outrigger mechanism of this embodiment utilizes the cavity within the outrigger body 1 as a receiving space 11 to accommodate the battery structure 2 and to power the entire vehicle using the battery structure 2, thereby improving the space utilization rate of the outrigger body 1.

[0029] It is worth noting that in this embodiment, the battery structure 2 is arranged inside the support leg body 1. Compared with the arrangement on the turret or chassis in related technologies, this can lower the center of gravity of the vehicle and make the vehicle structure more stable. Furthermore, by using the cavity inside the support leg body 1 to install the battery structure 2, the battery structure 2 that was originally installed on the turret or chassis can be appropriately reduced or completely removed. The remaining space can be used to arrange other components, improving the utilization rate of the vehicle space and making the overall vehicle layout easier.

[0030] In one embodiment, such as Figure 1 As shown, the outrigger mechanism also includes a rotary drive structure 3, which is connected to the outrigger body 1 via a transmission connection.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, the telescopic support structure 4 includes an electric cylinder 41, and a battery structure 2 is electrically connected to the electric cylinder 41. The electric cylinder 41 is used to provide telescopic support for the outrigger body 1, and the battery structure 2 inside the outrigger body 1 can supply power to the electric cylinder 41, which facilitates the application of the electric cylinder 41 and improves the working efficiency of the outrigger mechanism.

[0032] Furthermore, in one embodiment, such as Figure 1 and Figure 2 As shown, the telescopic support structure 4 also includes a support plate 42. The upper end of the electric cylinder 41 is connected to the support leg body 1, and the lower end of the electric cylinder 41 is connected to the support plate 42. The support plate 42 is used to abut against and support the support at the predetermined support position. The support plate 42 has a large support area to ensure the stability of the support.

[0033] In one embodiment, such as Figure 1 As shown, the rotary drive structure 3 includes a rotary motor, and the battery structure 2 is electrically connected to the rotary motor. The rotary motor drives the outrigger body 1 to rotate, and the battery structure 2 inside the outrigger body 1 can supply power to the rotary motor, which facilitates the application of the rotary motor and improves the working efficiency of the outrigger mechanism.

[0034] Specifically, in this embodiment, such as Figure 1 As shown, the rotary motor and the electric cylinder 41 are respectively located at opposite ends of the support leg body 1 along the length direction.

[0035] It is worth noting that when the outrigger mechanism is needed to support the vehicle body, the outrigger body 1 is driven to rotate outward away from the vehicle body by a rotary motor, so that the outrigger body 1 unfolds and the electric cylinder 41 extends to make the support plate 42 abut against the predetermined support position (e.g., the ground) for support; when the vehicle body does not need to be supported, the electric cylinder 41 retracts to make the support plate 42 move away from the predetermined support position, and the rotary motor drives the outrigger body 1 to rotate inward closer to the vehicle body, so that the outrigger body 1 retracts.

[0036] It should be noted that in related technologies, hydraulic drive is used to drive the rotation of the outrigger body 1 and the telescopic support structure 4. In this embodiment, however, electric drive is used to drive the rotation of the outrigger body 1 and the telescopic support structure 4, which has a higher response speed and thus improves work efficiency. Furthermore, the battery structure 2 and the electric drive components (motor and electric cylinder 41) are both correspondingly arranged on the outrigger body 1, which facilitates the connection between the battery structure 2 and the electric drive components to meet power supply requirements.

[0037] It should be further noted that the battery structure 2 installed inside the outrigger body 1 can also supply power to other electrical components on the vehicle.

[0038] In one embodiment, such as Figure 1 and Figure 3 As shown, the support leg body 1 includes an upper side plate 12 and a lower side plate 13 arranged vertically at intervals. The support leg body 1 also includes a reinforcing plate 14, the upper and lower sides of which are connected to the upper side plate 12 and the lower side plate 13 respectively, so as to form at least two receiving spaces 11 between the upper side plate 12 and the lower side plate 13. This arrangement ensures the load-bearing capacity of the support leg body 1 while making full use of each receiving space 11 within the support leg body 1.

[0039] In one embodiment, one or several reinforcing plates 14 are provided. The number of reinforcing plates 14 is specifically set according to the required structural strength of the support leg body 1 to meet the load-bearing capacity of the support leg body 1.

[0040] Specifically, in this embodiment, such as Figure 3 As shown, the upper side plate 12 and the lower side plate 13 are arranged in parallel, and a reinforcing plate 14 is provided, which is perpendicularly connected to both the upper side plate 12 and the lower side plate 13. The upper side plate 12, the lower side plate 13, and the reinforcing plate 14 all extend along the length direction of the leg body 1. Therefore, in a cross-section perpendicular to the length direction of the leg body 1, the upper side plate 12, the lower side plate 13, and the reinforcing plate 14 form an I-shaped structure. The reinforcing plate 14 separates the upper side plate 12 and the lower side plate 13 along the width direction of the leg body 1 to form two receiving spaces 11, and a battery structure 2 can be installed in each receiving space 11.

[0041] It should be noted that, in order to improve the structural strength of the leg body 1, two or more reinforcing plates 14 can be provided. For example, two reinforcing plates 14 are provided at intervals and are arranged in parallel. Therefore, in the cross section perpendicular to the length direction of the leg body 1, the upper side plate 12, the lower side plate 13 and the two reinforcing plates 14 form an II-shaped structure.

[0042] In one embodiment, such as Figures 1 to 3As shown, an opening is formed between the edges of the upper side plate 12 and the lower side plate 13. The support leg body 1 also includes a covering structure 15, which is connected to the upper side plate 12 and the lower side plate 13 and covers the opening. Specifically, both ends of the upper side plate 12 and the lower side plate 13 are connected and sealed along the length direction of the support leg body 1, and both sides of the upper side plate 12 and the lower side plate 13 are provided with openings along the width direction of the support leg body 1. The openings communicate with the receiving space 11 to facilitate the assembly and disassembly of the battery structure 2 through the openings. Furthermore, the openings are covered by the covering structure 15 to encapsulate the battery structure 2 inside the support leg body 1.

[0043] It is worth noting that, such as Figure 3 As shown, the left and right sides of the reinforcing plate 14 form receiving spaces 11 respectively. A left opening is formed between the left edge of the upper side plate 12 and the left edge of the lower side plate 13, and the left opening is connected to the left receiving space 11. A right opening is formed between the right edge of the upper side plate 12 and the right edge of the lower side plate 13, and the right opening is connected to the right receiving space 11. Both the left and right openings are covered by a covering structure 15.

[0044] It should be further explained that the covering structure 15 can be a skin, which can be welded to the upper side plate 12 and the lower side plate 13.

[0045] In one embodiment, the battery structure 2 is welded to the leg body 1; alternatively, the leg mechanism further includes fasteners, and the battery structure 2 and the leg body 1 are connected by fasteners. This configuration rigidly connects the battery structure 2 to the leg body 1, facilitating the installation and arrangement of the battery structure 2.

[0046] Of course, as an alternative implementation, the support leg mechanism also includes a flexible component connected between the battery structure 2 and the support leg body 1. By using the flexible component to mount the battery structure 2 onto the support leg body 1, when the support leg body 1 deforms under stress, the flexible component absorbs and buffers the deformation, preventing the deformation of the support leg body 1 from being directly transmitted to the battery structure 2 and avoiding any impact on the battery structure 2. Specifically, the flexible component can be a spring or a rubber pad.

[0047] In one embodiment, the battery structure 2 is provided with one or arranged in several.

[0048] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, along the length of the leg body 1, several battery structures 2 are sequentially arranged in each accommodating space 11.

[0049] It is worth noting that battery structure 2 can be a single battery cell or a battery pack.

[0050] It should be noted that heat exchange structures (heating / cooling), connecting lines, control modules, etc., can be arranged around the outer periphery of the battery structure 2. For example, a heat exchange structure can be set at the bottom of the battery structure 2, and connecting lines, control modules, etc. can be arranged at the top of the battery structure 2.

[0051] In one embodiment, such as Figure 1 and Figure 2 As shown, the outrigger mechanism also includes a battery management module 5, which is electrically connected to the battery structure 2. Specifically, the battery management module 5 includes a charging / discharging unit, a voltage conversion unit, a GPS unit, etc.

[0052] According to an embodiment of the present invention, another aspect provides an engineering machine including the aforementioned outrigger mechanism.
