Description

Technical Field

[0001] This utility model relates to the field of loaders, and in particular to a split movable anti-collision beam and an electric loader. Background Technology

[0002] An electric loader is a type of construction machinery that uses electricity as its power source, primarily used for loading, shoveling, bulldozing, and excavation. Compared to traditional diesel or gasoline-powered loaders, electric loaders have the following characteristics: 1. Environmental friendliness: Electric loaders produce no exhaust emissions, making them environmentally friendly and meeting energy conservation and emission reduction requirements. 2. Low noise: Without the noise of an internal combustion engine, electric loaders operate with lower noise levels, making them suitable for use in noise-sensitive areas. 3. Energy cost: The operating cost of electric loaders is generally lower than that of fuel-powered loaders because electricity costs are typically lower than fuel costs. 4. Maintenance cost: The maintenance cost of electric loaders is relatively low due to their fewer mechanical parts and relatively simple electric drive system. 5. Operational performance: Electric loaders typically have better acceleration and climbing ability because the electric motor can provide instant maximum torque. 6. Battery technology: Electric loaders rely on battery technology; battery range and charging speed are key factors affecting their working efficiency. 7. Applicable Scenarios: Due to their limited range and charging requirements, electric loaders are better suited for fixed-area or short-distance operations, such as warehouses, factory interiors, and ports. With the development of battery and electric drive technologies, the application scope of electric loaders is gradually expanding, and their advantages in environmental protection and economy are becoming increasingly prominent.

[0003] Currently, the battery boxes of electric loaders are located at the rear of the vehicle. Drivers may inadvertently cause the rear of the vehicle to collide with obstacles while reversing, leading to safety hazards such as damage to the battery boxes. Now, a crash beam has been added to the rear of electric loaders to address potential collisions during reversing.

[0004] In existing technologies, there are two main types of crash beams: the first type is directly locked to the rear of the vehicle, preventing rotation and obstructing rear maintenance space, making it inconvenient to use; the second type uses a flip-up crash beam, consisting of two side pillars and a central crash beam. The beam is locked to one side pillar via a hinge, while the other pillar provides fixation. However, in actual assembly and use, the entire crash beam is very heavy, weighing nearly 100kg, and its support relies entirely on the hinge on one side. This causes significant sagging on the other side, making it difficult to align with the mounting holes when opening or closing. Manual lifting is required to align it with the holes, which is very strenuous due to its weight, further complicating its use. Therefore, it is necessary to improve the current crash beam design. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a split movable anti-collision beam and an electric loader, which can effectively solve the problem of inconvenience in using the anti-collision beam of the existing electric loader.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A split-type movable anti-collision beam includes two anti-collision beam units; the two anti-collision beam units are symmetrically arranged on both sides of the rear of an electric loader, and the two anti-collision beam units can be opened or closed. Each anti-collision beam unit includes a column and a main frame; one side of the main frame is hinged to the column, and the other side of the main frame is detachably locked to the rear of the electric loader through a fixing mechanism.

[0008] As a preferred embodiment, both anti-collision beam units can be set to open 180°.

[0009] As a preferred embodiment, one side of the main frame is hinged to the column.

[0010] As a preferred embodiment, the hinges are two hinges spaced vertically apart.

[0011] As a preferred embodiment, one side of the hinge is fixedly connected to the column by a first bolt, and the other side of the hinge is welded and fixed to the side of the main frame.

[0012] As a preferred embodiment, the fixing mechanism includes a fixing base and a locking pin. The fixing base is provided with two arms, which are arranged one above the other. A slot is formed between the two arms for the edge of the main frame to be engaged. Each arm has a pin hole at its tail end. The locking pin is inserted into the pin hole to lock the edge of the main frame in the slot.

[0013] As a preferred embodiment, a rubber pad is fixed in the slot, which makes elastic contact with the main frame, resulting in a simple structure and stable assembly.

[0014] As a preferred embodiment, the rubber pad is fixedly connected to the mounting base by a second bolt.

[0015] As a preferred embodiment, the support arm is welded to the fixed base, and a triangular reinforcing plate is welded between the outer side of the support arm and the fixed base to enhance the connection strength.

[0016] An electric loader, wherein the electric loader is equipped with the aforementioned split movable anti-collision beam.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0018] By symmetrically placing two anti-collision beam units on both sides of the rear of the electric loader, replacing the traditional integral structure, the anti-collision beam is divided into two parts from the middle and fixed to the two side columns respectively. The installation point is moved to the middle position, greatly reducing the weight of a single anti-collision beam unit, making installation and opening very easy and bringing convenience to use.

[0037] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a split movable anti-collision beam according to a preferred embodiment of the present invention, which includes two anti-collision beam units 10.

[0038] The two anti-collision beam units 10 are symmetrically arranged on both sides of the rear of the electric loader 100, and can be opened or closed. Each anti-collision beam unit 10 includes a column 11 and a main frame 12; one side of the main frame 12 is hinged to the column 11, and the other side of the main frame 12 is detachably locked to the rear of the electric loader 100 through a fixing mechanism 13. In this embodiment, both anti-collision beam units 10 can be opened 180°. Specifically:

[0039] The column 11 is a square straight tube structure, mainly made of high-strength steel, and has good structural strength.

[0040] One side of the main frame 12 is hinged to the column 11 via a hinge 14, resulting in a simple structure and easy assembly. Furthermore, two hinges 14 are spaced apart vertically, ensuring a more stable connection. One side of each hinge 14 is fixedly connected to the column 11 via a first bolt 15, while the other side of the hinge 14 is welded to the side of the main frame 12. In this embodiment, the main frame 12 is formed by welding steel pipes 121, which are round tubes. A connecting piece 122 is fitted onto the side of the steel pipe 121, and this connecting piece 122 is welded to the hinge 14.

[0041] The fixing mechanism 13 includes a fixing base 131 and a locking pin 132. Two arms 133 are mounted on the fixing base 131, arranged vertically. A slot 101 is formed between the two arms 133 for the edge of the main frame 12 to engage. Each arm 133 has a pin hole 102 at its tail end. The locking pin 132 is inserted into the pin hole 102 to lock the edge of the main frame 12 in the slot 101. A rubber pad 134 is fixed in the slot 101. The rubber pad 134 elastically contacts the main frame 12 to provide adjustment and cushioning, effectively preventing noise caused by vibration of the main frame 12 during driving. It also effectively prevents assembly errors from causing positional deviations of the main frame 12, ultimately preventing assembly failure. Furthermore, the rubber pad 134 is fixedly connected to the fixing base 131 by a second bolt 135, resulting in a simple structure and stable assembly. In addition, the support arm 133 is welded and fixed to the fixed base 131, and a triangular reinforcing plate 136 is welded between the outer side of the support arm 133 and the fixed base 131, resulting in good assembly structure strength. Furthermore, the upper end of the locking pin 132 has a lifting ring 103, and the lower end of the locking pin 132 is fitted with an anti-disengagement spring 137 to prevent the locking pin 132 from coming out upwards, ensuring that the locking pin 132 is inserted into the pin hole 102 to lock the main frame 12.

[0042] This utility model also discloses an electric loader 100, which is equipped with the aforementioned split movable anti-collision beam. In this embodiment, the lower end of the column 11 is fixedly connected to the box-shaped structure of the rear frame of the electric loader 100 by a third bolt 104, and the fixing seat 131 is fixedly connected to the middle position of the rear of the electric loader 100 by a fourth bolt 105.

[0043] The usage method of this embodiment is described in detail below:

[0044] In use, the two anti-collision beam units 10 can be opened and closed independently and conveniently at any time. Specifically, pull out the anti-detachment spring 137, then pull out the locking pin 132 upwards, and then pull the main frame 12 outwards. The main frame 12 can then rotate around the column 11 to open. To close, push the main frame 12 inwards. After pushing it into place, the lower edge of the main frame 12 will engage in the slot 101. Then, insert the locking pin 132 into the pin hole 102 and install the anti-detachment spring 137. When it is necessary to repair the battery pack from the rear of the electric loader 100, the two anti-collision beam units 10 can be opened 180 degrees to both sides for easy repair. During normal operation, the two anti-collision beam units 10 can be locked to protect the battery. The weight of the two anti-collision beam units 10 is 45% of that of the previous integrated anti-collision beams, which effectively solves the problem that the anti-collision beam will sag significantly on the other side when locked on a single hinge. The lighter weight also makes it more convenient to open and close the anti-collision beams in practice.

[0045] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
