Description

Technical Field

[0001] This utility model relates to the field of equipment protection technology, and in particular to an automatic rebound bellows cover. Background Technology

[0002] In equipment-intensive applications such as industrial production and logistics, the safety protection of critical equipment components (such as high-voltage power interfaces, precision sensors, and controllers) is of paramount importance. If these components are exposed, they are highly susceptible to accidental contact by personnel, leading to safety accidents. Furthermore, they are easily affected by environmental factors such as dust, liquids, and foreign objects, resulting in equipment malfunctions or performance degradation.

[0003] Currently, the following methods are mainly used to protect critical components of equipment:

[0004] 1. Rubber protective cover. This type of structure has significant drawbacks: First, production requires custom molds, resulting in high initial investment costs, especially for small batches or non-standard equipment; second, the structure is fixed, making it difficult to flexibly adapt to parts of different shapes, sizes, or positions, resulting in poor versatility; third, the rubber material is prone to aging and deformation under repeated opening and closing or high-temperature environments, causing the reliability of protection to decrease over time.

[0005] 2. Electric / Pneumatic Protective Structure. This type of structure typically uses motors, cylinders, or other drive mechanisms to automatically open and close the protective cover. While it provides some active protection, its complex structure relies on external power sources, air supply, sensors, and sophisticated control systems, significantly increasing the overall equipment cost. Furthermore, its installation and commissioning are cumbersome, and subsequent maintenance and troubleshooting are difficult. The system's reliability is also dependent on the stability of multiple related components.

[0006] 3. Bellows Cover with Torsion Spring Rebound Mechanism. Current technology often uses a built-in torsion spring mechanism to provide rebound force for the bellows cover folds, enabling automatic closure of the cover when not in operation. However, this torsion spring rebound solution has several inherent drawbacks: the torsion spring needs to be installed on the pivot, occupying a large volume within the narrow internal space of the bellows cover folds, easily increasing the overall thickness of the bellows cover; the installation process requires high precision in assembly, ensuring that the two torsion arms accurately abut against specific side walls of the upper and lower rods, otherwise the rebound force will weaken, become uneven, or even fail; maintenance is extremely inconvenient, as replacement often requires disassembling the entire pivot, upper rod, and lower rod assembly, and may even require disassembling part of the bellows cover body; during repeated torsion, the stress concentration at the root of the torsion spring is significant, making it more prone to fatigue fracture compared to tension / compression springs; under the high-temperature conditions encountered in industrial environments, the elastic modulus and fatigue strength of the torsion spring material will decrease rapidly, and stress relaxation is likely to occur, leading to a decrease in rebound force or even failure.

[0007] There is an urgent need to develop a new type of protective device to address the aforementioned shortcomings. Summary of the Invention

[0008] The purpose of this utility model is to provide an automatic rebound accordion cover, which has the advantages of low cost, simple structure, convenient maintenance and high reliability.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An automatic rebound accordion cover includes a mounting plate, an accordion cover body, a movable plate, a base, a guide post, a spring, a nut, and screws. The mounting plate is used to fix the device to the equipment. The accordion cover body connects the mounting plate and the movable plate, serving to shield and protect key internal components of the equipment. The movable plate is connected to the accordion cover body and is used to drive the accordion cover body to extend and retract. The base is fixed in a pre-drilled mounting hole on the mounting plate by the nut, ensuring a firm connection between the base and the mounting plate. One end of the guide post is connected to the movable plate by the screw, and the other end is connected to the base, providing guidance for the movement of the movable plate. The spring is sleeved on the guide post, with one end fixed to the base and the other end abutting against the movable plate, in a pre-compressed state to ensure automatic rebound.

[0011] Furthermore, the spring constant and length can be selected and adjusted according to actual needs to ensure that the bellows cover can achieve a stable and reliable automatic rebound function in different usage scenarios.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] First, it eliminates the need for mold making, avoiding high upfront investment, and eliminates complex components, reducing the costs of power supply, air supply, sensors, and control systems, resulting in a significant reduction in overall cost. Second, it overcomes the limitations of the fixed structure of rubber protective covers, and can be adapted to equipment parts of different shapes and sizes by simply adjusting the parameters of the mounting plate and elastic mechanism, making it highly versatile.

[0014] Secondly, when the Automated Guided Vehicle (AGV) approaches the pressing movable plate, the bellows cover automatically retracts; when the AGV leaves, it automatically resets, the process is smooth and requires no additional intervention; the components of this device are easy to replace, daily inspection and maintenance are easy, and operation and maintenance costs are reduced.

[0015] Third, it is composed of basic mechanical components, has a simple structure, and the spring pre-compression design ensures initial stability. The reset action is quick and reliable, reducing potential failures and ensuring high reliability. It adopts a spring-guide column structure, which ensures stable operation and is less affected by environmental interference. Attached Figure Description

When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0022] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0023] like Figures 1-3As shown, this utility model provides an automatic rebound accordion cover, including a mounting plate 1, an accordion cover body 2, a movable plate 3, a base 4, a guide post 5, a spring 6, a nut 7, and screws 8. The mounting plate 1 is the basic mounting component of the entire device, used to fix the accordion cover to the equipment and provide mounting support for other components. The accordion cover body 2 connects the mounting plate 1 and the movable plate 3, serving to shield and protect key internal components of the equipment. The movable plate 3 is connected to the accordion cover body 2 and is used to drive the accordion cover body 2 to extend and retract. The base 4 has its own threads and limiting blocks, and is fixed in the mounting hole pre-drilled on the mounting plate 1 by the nut 7 to ensure the base... The base 4 is firmly connected to the mounting plate 1; one end of the guide post 5 is fixedly connected to the pre-set connection hole on the movable plate 3 by the screw 8, and the other end is inserted into the corresponding guide hole on the base 4, providing guidance for the movement of the movable plate 3 and ensuring that the movable plate 3 can only move along the axial direction of the guide post 5; the spring 6 is sleeved on the guide post 5, ensuring that the axis is consistent with the axis of the guide post 5. One end of the spring 6 is fixed to the base 4, and the other end abuts against the movable plate 3, used to store and release elastic potential energy. During installation, it is in a pre-compressed state, providing initial restoring force for the movable plate 3 and ensuring that it can automatically rebound.

[0024] Preferably, the elastic coefficient and length of the spring 6 can be selected and adjusted according to actual needs. The elastic coefficient is dynamically adjusted according to the unfolding resistance and load weight of the bellows cover 2, and the length is matched according to the stroke of the guide post 5, so as to ensure that the bellows cover can achieve a stable and reliable automatic rebound function in different usage scenarios.

[0025] The installation process of this utility model is as follows: Based on the equipment structure and protection requirements, a suitable installation position is selected. Using installation tools, the mounting plate 1 is fixed to the equipment requiring protection, ensuring that the mounting plate 1 is firmly installed and its installation surface is flat, laying the foundation for the accuracy of subsequent component installation. During installation, tools are used to measure and ensure that the horizontal and vertical alignment of the mounting plate 1 meets the standards. A base 4 is installed in the mounting hole of the mounting plate 1, and the base 4 is tightened onto the mounting plate 1 using nuts 7. The tightening torque of the nuts 7 is controlled to prevent excessive tightness or looseness from affecting the stability of the base 4. A guide post 5 is installed in the connection hole of the movable plate 3, and the guide post 5 is fixed to the movable plate 3 with screws 8, ensuring a tight connection between the guide post 5 and the movable plate 3, and that the axial direction of the guide post 5 is consistent with the direction of movement of the movable plate 3. A spring 6 is fitted onto the guide post 5. During installation, a certain pre-compression is applied to the spring 6 to ensure that its two ends are fixedly abutting against the base 4 and the movable plate 3 respectively. This ensures that the spring 6 is in a compressed state even without external force, providing a continuous restoring thrust to the movable plate 3, and allowing it to freely expand and contract on the guide post 5. Connect one end of the accordion cover 2 to the mounting plate 1 by welding to ensure a firm and reliable connection. Connect the other end of the accordion cover 2 to the movable plate 3, also ensuring a tight connection so that the accordion cover 2 will not fall off or loosen when it extends or retracts.

[0026] When using this invention, before the Automated Guided Vehicle (AGV) operates, the operator must check the automatic rebound bellows cover to ensure that the bellows cover 2 is fully extended, covering the key components of the equipment, and that the elastic mechanism is functioning normally. Check whether the movable plate 3 can move freely and whether the spring 6 is deformed or damaged; address any problems promptly. When the AGV approaches and presses against the movable plate 3, the movable plate 3, under the pressure of the AGV, overcomes the preload of the spring 6 and the elastic force generated by its further compression, moving relative to the mounting plate 1 along the guide post 5. The bellows cover 2 then retracts, allowing the AGV to smoothly contact the protected components. After the AGV completes its operation and leaves, the preload of the spring 6 and its stored elastic potential energy push the movable plate 3 back to its original position along the guide post 5, and the bellows cover 2 automatically unfolds and resets, once again protecting the internal components.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related fields, are similarly included within the patent protection scope of this utility model.
