Description

Technical Field

[0001] The present application relates to buffering and shock absorption technology and power safety protection technology in the mechanical field, and in particular to a buffering and shock absorption system and an integrated charging cabinet. Background Art

[0002] Buffering and shock absorption systems play an important role in modern industrial equipment, especially in situations where they need to withstand frequent impact loads. These systems can effectively absorb and disperse energy, reduce the impact on internal components of the equipment, and thus improve the reliability and service life of the equipment. In addition, with the improvement of industrial automation levels, various types of mechanical equipment have higher and higher requirements for impact resistance, which makes efficient and reliable buffering and shock absorption systems an indispensable key component.

[0003] Existing buffering and shock absorption technologies mainly rely on traditional components such as springs and hydraulic cylinders to achieve the shock absorption function. Specifically, common methods include using a combination of springs with different stiffnesses to adjust the shock absorption effect, or using the flow of oil in the hydraulic cylinder to absorb impact energy. In addition, there is a method of achieving buffering through rubber blocks or air cushions. Such solutions usually have better energy absorption effects and longer service life. However, although the above-mentioned methods can meet the shock absorption needs to a certain extent, there are still some shortcomings in practical applications.

[0004] There is a common problem with the buffering and shock absorption systems in the prior art, that is, it is impossible to provide differentiated protection according to the intensity of the collision, especially when encountering a large impact force, it is impossible to guarantee that the equipment will not affect the safety of the surrounding environment in the future. For example, when encountering a strong impact, traditional springs or hydraulic cylinders may not be able to respond quickly and fully absorb the impact energy, causing damage to the internal circuit of the equipment or even causing a safety accident, especially in the charging cabinets that are gradually becoming popular. Therefore, there is an urgent need for a new buffering and shock absorption system that can not only efficiently absorb impact force but also ensure the safety of the equipment in the future. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the present application provides a buffer shock absorption system and an integrated charging cabinet. The buffer shock absorption system can distinguish the collision intensity and ensure the safety of the equipment while absorbing greater impact force.

[0006] This application is implemented through the following technical solutions: A buffering and shock absorbing system, comprising: A buffer, the buffer comprising a bottom plate and an air blowing device, the bottom plate is provided with at least two parallel guide posts, the guide posts are slidably connected with an outer plate and an intermediate plate in sequence from outside to inside; a first spring is provided between the bottom plate and the intermediate plate, a second spring is provided between the intermediate plate and the outer plate, and the elastic coefficient of the first spring is greater than that of the second spring; the air blowing device is placed between the bottom plate and the intermediate plate, and is used to convert the impact force borne by the intermediate plate into impact air pressure; A pneumatic power supply protection switch, which is used to connect the device to an external circuit, and can drive the device to disconnect from the external circuit under the action of impact air pressure; An air-conducting connector is used to guide the impact air pressure generated in the buffer into the pneumatic power supply protection switch.

[0007] By adopting the above technical solution, the buffer shock absorption system can effectively absorb and disperse the impact energy. Specifically, the arrangement of the first spring and the second spring allows impact forces of different intensities to be gradually absorbed. When encountering a smaller collision, the second spring close to the collision source can be relied on to slow down the impact force to ensure that the equipment is not damaged. When encountering a very large collision, the first spring and the second spring can prevent excessive impact from being directly transmitted to the inside of the equipment, thereby improving the seismic performance of the system. The change in the expansion and contraction amount of the first spring will trigger the inflation device to form impact air pressure, prompting the equipment to cut off the connection with the main power supply in time to ensure the safety of the equipment. The inflation device will reduce the impact force borne by the middle plate. It is converted into impact air pressure, further dispersing the impact energy and reducing the wear between mechanical parts; the pneumatic power supply protection switch can quickly cut off the connection between the equipment and the external circuit under the action of impact air pressure, avoiding electrical failure or damage caused by impact, and ensuring the safe operation of the equipment; the air guide connector can efficiently introduce the impact air pressure generated by the buffer into the pneumatic power supply protection switch, ensuring that the pneumatic power supply protection switch responds to the impact event in time and enhancing the reliability and stability of the system; in summary, the buffer shock absorption system not only improves the impact resistance of the equipment, but also significantly enhances the ability of the equipment to automatically protect itself in emergency situations, thereby improving the overall safety and service life.

[0008] Optionally, the inflation device is an airbag; the upper end of the airbag is fixed to the middle plate, the lower end is fixed to the bottom plate, and the bottom plate is provided with an air guide head connected to the inner cavity of the airbag.

[0009] By adopting the above technical solution, the airbag has a simple structure and low manufacturing cost, and can effectively absorb and buffer external impact force and convert it into internal air pressure changes, thereby reducing direct collisions between mechanical components; the air guide head can facilitate the installation of the air guide pipe and enhance the stability of the equipment.

[0010] Optionally, the inflation device includes a cylinder body fixed on the bottom plate, a piston adapted to the cylinder body is provided on the middle plate, an air guide head connected to the inner cavity of the cylinder body is provided on the bottom plate, and a breathable capillary hole connected to the inner cavity of the cylinder body is provided at the root of the cylinder body.

[0011] By adopting the above technical solution, when the impact force acts on the middle plate, the piston moves in the cylinder, converts the impact force into air pressure and transmits it to the pneumatic power protection switch through the air guide head; at the same time, the cylinder structure improves the stability and reliability of the system and prevents damage caused by impact; the design of breathable capillaries enables the airbag to quickly discharge gas when under pressure, relieve instantaneous high pressure, and slowly return to its original state when the pressure is released, ensuring the stability and reliability of the system.

[0012] Optionally, the first spring and the second spring are both sleeved on the guide column.

[0013] By adopting the above technical solution, the first spring and the second spring are both sleeved on the guide column, so that the two springs can be more stably distributed around the guide column, ensuring that under the action of external force, each part of the buffer is evenly stressed, thereby improving the overall stability of the system. At the same time, this structural design also simplifies the assembly process and reduces production costs.

[0014] Optionally, the air connector includes a sealed cavity, on which an air outlet and a plurality of air inlets are evenly distributed, the air outlet is connected to the pneumatic power supply protection switch via an air duct, and the air inlet is connected to the inflation device via an air duct.

[0015] By adopting the above technical solution, the sealed cavity can effectively integrate the impact air pressure from multiple air inlets and evenly distribute it to each air outlet, ensuring the stability of air pressure transmission. Specifically, this design enables the air connector to have good airflow organization capabilities, avoiding the problem of malfunction of the protection switch caused by uneven air pressure distribution; at the same time, the connection of the air duct between the air inlet and the air blowing device ensures that the air pressure transmission path is unobstructed, while the connection of the air duct between the air outlet and the pneumatic power supply protection switch further improves the response speed and reliability.

[0016] Optionally, a one-way valve is provided on the air inlet.

[0018] Optionally, the pneumatic power supply protection switch includes a terminal block fixed on the base, a guide seat, a connecting plate and a pneumatic locking device, the terminal block is provided with a female terminal connected to the equipment circuit and a male terminal connected to the external circuit; the guide seat is provided with a sliding hole; the connecting plate is slidably connected in the sliding hole through a sliding rod arranged on the back, and a contact head for connecting the female terminal with the male terminal is provided at the bottom of the connecting plate; a first elastic member is provided between the guide seat and the connecting plate to drive the connecting plate away from the terminal block, and the pneumatic locking device is used to limit the position of the connecting plate and drive the female terminal and the male terminal to be in a connected state.

[0019] By adopting the above technical solution, the pneumatic power supply protection switch can maintain stable connection between the equipment and the external circuit under normal conditions, ensuring the normal use of the equipment and power supply; when the buffer is impacted, the inflation device converts the impact force into impact air pressure and transmits it to the pneumatic power supply protection switch through the air connector, driving the pneumatic locking device to release the restriction on the connecting plate, and the connecting plate is moved away from the terminal block under the action of the first elastic member, so that the female terminal is disconnected from the male terminal, thereby quickly cutting off the connection between the equipment and the external circuit, effectively preventing electrical failures or safety accidents caused by impact; at the same time, the design of the pneumatic locking device ensures the stability of the connection state under non-impact conditions, thereby improving the reliability and safety of the system.

[0020] Optionally, the pneumatic locking device includes a valve sleeve, in which a valve core is slidably connected; the head of the valve core extends out of the valve sleeve and is clamped with a connecting plate; an expansion chamber is provided between the valve sleeve and the valve core, and when external gas is introduced into the expansion chamber, the valve core can be driven out of contact with the connecting plate; and an elastic part is provided at the tail of the valve core for driving the valve core to clamp the connecting plate.

[0021] By adopting the above technical solution, precise control of the position of the connecting plate in the pneumatic power protection switch is achieved. Specifically, the expansion chamber between the valve sleeve and the valve core can generate pressure when external gas is introduced, effectively pushing the valve core to move, thereby releasing the restriction on the connecting plate, so that the connecting plate is away from the terminal board under the action of the elastic member, thereby achieving the effect of disconnecting the circuit. At the same time, the elastic member arranged at the tail of the valve core ensures that when no external gas is introduced, the valve core can stably abut the connecting plate, maintain the connection state between the female terminal and the male terminal, and ensure the normal operation of the equipment. This design improves the reliability and response speed of the system, and enhances the safety performance of the charging cabinet when it is impacted.

At the same time, the pneumatic power protection switch automatically cuts off the connection with the external circuit under the impact, improving the safety and reliability of the system; in addition, the design of the air guide connector ensures the effective transmission of impact air pressure, further enhancing the stability and response speed of the entire system.

[0025] By adopting the above technical solution, the connecting rod connects the upper and lower buffers, and the use of a small number of buffers makes the entire buffer and shock absorption system more integrated, effectively transmits and disperses the impact force, improves the reliability and durability of the system, and saves production costs.

[0026] Further optionally, the fixing seat includes a base and a cover plate, and the base is provided with an opening groove adapted to the connecting rod; the cover plate is fixed to the opening groove by a locking bolt to apply extrusion force to the connecting rod.
