Description

Technical Field

[0001] This utility model belongs to the field of door closer equipment, and specifically relates to an electric floor spring with protective function. Background Technology

[0002] An electric floor spring is a device installed at the bottom of a door, integrating electric drive and the functions of a traditional floor spring. It is mainly used for automatically controlling the opening and closing of doors. Currently, even with its own protective casing, the protective effect of electric floor springs is still limited. When subjected to accidental impacts, such as sudden external force, the lack of cushioning and overload protection structures makes the internal spring components prone to deformation and breakage due to excessive instantaneous force. The motor may also suffer from overload, resulting in winding burnout and damage to transmission components. The current conventional approach is to increase the strength and durability of internal components, such as using high-strength spring materials and high-power motors. However, this significantly increases manufacturing costs. High-strength springs increase door opening and closing resistance, affecting the user experience. High-power motors not only increase energy consumption but also increase the overall size of the electric floor spring, reducing its adaptability. Furthermore, simply reinforcing components cannot fundamentally eliminate the damage caused by impacts; if the impact force exceeds the component's limit, damage will still occur. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric floor spring with protective function to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: an electric floor spring with protective function, comprising: a housing assembly, a spring assembly, and a protective assembly. The housing assembly has a protective assembly installed inside for protecting the spring assembly. The spring assembly is installed between the protective assemblies. The housing assembly includes a bottom shell and a cover plate for installation. The cover plate is installed on the upper surface of the bottom shell. The protective assembly includes a bottom plate and a protective plate. A buffer post is installed between the bottom plate and the protective plate. The spring assembly is installed on the upper surface of the bottom plate.

[0005] In a preferred embodiment, the upper surface of the bottom shell is designed to be open, and the upper surface of the bottom shell is recessed downward to form a groove. Two fixing plates are symmetrically installed on the left side surface inside the bottom shell. A cover plate is installed at the opening on the upper surface of the bottom plate, and a groove is formed on the left edge of the upper surface of the cover plate to the right.

[0006] In a preferred embodiment, a protective cover is installed inside the groove of the cover plate. The surface of the protective cover has a circular through hole, and a sealing ring is glued to the inner wall of the circular through hole. The spring assembly includes a spring body, a top cover, a rotating component, and a fixing component. During use, the bottom shell and the cover plate cooperate with each other to form a relatively closed space, which can effectively prevent dust, debris, and moisture from entering the electric floor spring. This can prevent dust from accumulating on the spring assembly components, avoid problems such as accelerated wear of components and poor transmission caused by excessive dust, and extend the service life of the electric floor spring.

[0007] In a preferred embodiment, a top cover is installed on the upper surface of the spring body. The top cover is made of hard rubber. A fixing member is installed on the left side surface of the spring body. A rotating member is installed on the right side of the upper surface of the spring body. The rotating member passes through the top cover, the cover plate, and the protective plate.

[0008] In a preferred embodiment, a base plate is installed at the bottom inside the bottom shell, and a spring body is installed on the upper surface of the base plate by means of a fastener and a fixing plate. Multiple buffer posts are evenly installed on the front and rear edges of the upper surface of the base plate.

[0009] In a preferred embodiment, the plurality of buffer columns have the same structure. Each buffer column is a spring damper. A protective plate is installed on each buffer column away from the base plate. The structure of the protective plate matches the structure of the base plate. The protective plate is positioned above the spring body. In use, the buffer column is installed between the base plate and the protective plate. When subjected to a large impact force from an external force, the buffer column, together with the protective plate and the cover plate, can absorb and buffer some of the energy. Combined with the outer shell assembly, this can reduce the impact force transmitted to the spring assembly, prevent the spring from deforming or being damaged due to excessive force, and extend the service life of the spring.

[0010] In a preferred embodiment, the upper surface of the protective plate is connected to the lower surface of the cover plate, and a protective cover is installed at the connection between the rotating component and the cover plate via a groove.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting the outer shell assembly, the spring assembly is installed between the protective components. The outer shell assembly includes a bottom shell for installation and a cover plate. The cover plate is installed on the upper surface of the bottom shell. When in use, the bottom shell and the cover plate cooperate with each other to form a relatively closed space, which can effectively prevent dust, debris and moisture from entering the electric floor spring. This can prevent dust from accumulating on the spring assembly components, avoid problems such as accelerated wear of components and poor transmission caused by excessive dust, and extend the service life of the electric floor spring.

[0012] 2. By setting up a protective component, a protective component is installed inside the outer casing to protect the spring assembly. The protective component includes a base plate and a protective plate, with a buffer post installed between the base plate and the protective plate. The spring assembly is installed on the upper surface of the base plate. During use, the buffer post is installed between the base plate and the protective plate. When subjected to a large impact force, the buffer post, together with the protective plate and the cover plate, can absorb and buffer some of the energy. Combined with the outer casing, this can reduce the impact force transmitted to the spring assembly, prevent the spring from deforming or being damaged due to excessive force, extend the service life of the spring, ensure that the spring assembly can work stably for a long time, and maintain the normal opening and closing control function of the electric floor spring for the door.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 As the first embodiment of this utility model: an electric floor spring with protective function, including: a housing assembly, a spring assembly 200 and a protective assembly, the housing assembly is equipped with a protective assembly for protecting the spring assembly 200, the spring assembly 200 is installed between the protective assemblies, the housing assembly includes a bottom shell 100 for installation and a cover plate 110, the cover plate 110 is installed on the upper surface of the bottom shell 100, the protective assembly includes a bottom plate 300 and a protective plate 310, a buffer post 320 is installed between the bottom plate 300 and the protective plate 310, and the spring assembly 200 is installed on the upper surface of the bottom plate 300;

[0024] The upper surface of the bottom shell 100 is designed with an opening. The upper surface of the bottom shell 100 is recessed downward to form a groove. Two fixing plates 101 are symmetrically installed on the left side surface inside the bottom shell 100. A cover plate 110 is installed at the opening on the upper surface of the bottom plate 300. A groove is opened to the right on the left edge of the upper surface of the cover plate 110.

[0025] A protective cover 120 is installed inside the groove of the cover plate 110. A circular through hole is opened on the surface of the protective cover 120. A sealing ring is glued to the inner wall of the circular through hole. The spring assembly 200 includes a spring body 210, an upper cover 220, a rotating part 230, and a fixing part 240.

[0026] A cover 220 is installed on the upper surface of the spring body 210. The cover 220 is made of hard rubber. A fixing part 240 is installed on the left side surface of the spring body 210. A rotating part 230 is installed on the right side of the upper surface of the spring body 210. The rotating part 230 passes through the cover 220, the cover plate 110 and the protective plate 310.

[0027] When in use, the user first installs the outer shell assembly consisting of the bottom shell 100 and the cover plate 110 in a suitable position. After installation, when the device is impacted, the cover plate 110 and the bottom shell 100 can provide initial protection for the internal spring assembly 200. After the impact reaches the inside of the outer shell assembly, the protective components can provide secondary protection. Then, the upper cover 220 on the upper surface of the spring body 210 inside the spring assembly 200 can also provide protection, thereby greatly improving the safety of the spring assembly 200 during use and improving the protective effect of the device. Since the bottom shell 100 and the cover plate 110 cooperate with each other to form a relatively closed space during use, they can effectively prevent dust, debris and moisture from entering the electric floor spring. This can prevent dust from accumulating on the spring assembly 200 components, avoid problems such as accelerated wear and poor transmission caused by excessive dust, and extend the service life of the electric floor spring.

[0028] Please see Figures 1 to 5 As a second embodiment of the present invention: based on the description in the above embodiments, further, a bottom plate 300 is installed at the bottom inside the bottom shell 100, and a spring body 210 is installed on the upper surface of the bottom plate 300 through a fastener 240 and a fastener 101. Multiple buffer posts 320 are evenly installed on the front and rear edges of the upper surface of the bottom plate 300.

[0029] Multiple buffer pillars 320 have the same structure. The buffer pillar 320 is a spring damper. A protective plate 310 is installed on the buffer pillar 320 away from the base plate 300. The structure of the protective plate 310 matches the structure of the base plate 300. The protective plate 310 is located above the spring body 210.

[0030] The upper surface of the protective plate 310 is connected to the lower surface of the cover plate 110, and the protective cover 120 is installed at the connection between the rotating part 230 and the cover plate 110 through a groove.

[0031] In use, when the spring assembly 200 inside the housing assembly is protected as a first layer of protection through the operation steps of the first embodiment, the protective component inside the housing assembly can provide a second layer of protection. When the protective plate 310 on the upper surface of the protective component is subjected to the impact transmitted by the first embodiment, the protective plate 310 will compress the buffer column 320 on its lower surface (the buffer column 320 is a hydraulic spring buffer column 320, the specific working principle and structure of which will not be described in detail here), causing the buffer column 320 to drive the protective plate 310 down, so that the lower surface of the protective plate 310 contacts the upper cover 220 of the spring assembly 200, from... To prevent the impact from being directly transmitted to the spring assembly 200, thus protecting the spring assembly 200, the buffer post 320 is installed between the base plate 300 and the protective plate 310 during use. When subjected to a large impact force from an external force, the buffer post 320, together with the protective plate 310 and the cover plate 110, can absorb and buffer some of the energy. Combined with the outer shell assembly, this can reduce the impact force transmitted to the spring assembly 200, prevent the spring from deforming or being damaged due to excessive force, extend the service life of the spring, ensure that the spring assembly 200 can work stably for a long time, and maintain the normal opening and closing control function of the electric floor spring for the door.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
