[0001] The invention belongs to the technical field of plastic shell control housings, and in particular relates to an anti-collision and buffering plastic shell control housing and a use method thereof. Background Art

[0002] A molded case control housing, usually referred to as a molded case, is a housing used to protect and encapsulate electronic or electrical control components. The molded case control housing is mainly made of plastic materials and has a wide range of applications in the electrical and electronic industries, especially in scenarios where internal circuits and control components need to be protected from environmental interference, pollution or physical damage; Since the plastic shell often integrates key components such as precision electronic components and circuit boards, if there is no effective anti-collision buffer mechanism, these core components are easily damaged once they encounter external impact or collision, which may cause device failure or performance degradation. At present, plastic shell control housings mainly rely on buffer materials to achieve anti-collision and buffering functions. However, the energy absorption capacity of this material is limited, and it is easy to age, harden or degrade with time and changes in the use environment, which greatly reduces its anti-collision and buffering performance and may eventually cause the risk of damage to the housing or internal equipment. Summary of the invention

[0003] The object of the present invention is to provide a collision-proof and buffering plastic shell control housing and a method of using the same, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above object, the present invention provides the following technical solution: an anti-collision and buffering plastic shell control housing, comprising a housing, a buffer assembly is arranged inside the housing, a top cover is installed on the top end of the housing by bolts, a base is fixedly installed on the bottom end of the housing, and a support assembly is arranged on the outer wall of the housing; Wherein, the buffer assembly includes a damper and an airbag arranged inside the shell, the damper and the airbag are evenly distributed, and each of the damper and the airbag is correspondingly arranged.

[0006] As a further technical solution of the present invention, the support assembly includes a support plate arranged on the outer wall of the shell, and two support plates are provided. Both support plates are rotatably installed inside the top cover through a rotating shaft, and a torsion spring is installed on the outer wall of the rotating shaft. A limiting assembly is arranged between the support plate and the top cover.

[0007] As a further technical solution of the present invention, the limit assembly includes a limit rod arranged inside the top cover, one end of the limit rod is fixedly connected to a third connecting rod, a spring is arranged on one side of the third connecting rod, one end of the third connecting rod is fixedly installed with a moving rod, the top of the moving rod is provided with a second protrusion, the second protrusion is fixedly installed on the bottom end of the second connecting rod, the second connecting rod is slidably installed inside the top cover, the bottom end of the second connecting rod is fixedly installed with a first connecting rod, the end of the first connecting rod away from the second connecting rod is fixedly connected with a first protrusion, the first protrusion is embedded in the interior of a slide groove, the slide groove is opened inside the base, and a sphere is arranged inside the slide groove.

[0008] As a further technical solution of the present invention, the slide groove is arranged inclined.

[0009] As a further technical solution of the present invention, the slide grooves are evenly distributed in a ring array.

[0010] As a further technical solution of the present invention, a support pad is fixedly connected to the bottom end of the support plate.

[0011] As a further technical solution of the present invention, a limit block is fixedly installed on the outer wall of the rotating shaft, and the limit block is slidably installed inside the limit groove.

[0012] As a further technical solution of the present invention, one side of the limit rod is inclined.

[0013] A method for using a collision-proof and buffering plastic shell control housing comprises the following steps: S1: When the shell is hit by an external impact, the energy generated by the impact is first absorbed and dissipated by the damper. When the damper is displaced by a certain impact energy, it contacts the surface of the airbag, and further absorbs the impact energy through the airbag. When the airbag is hit, the surface will deform to a certain extent. The deformation of the airbag presses the dynamic pressure block to move inward, squeezing the gas inside the airbag into the air cavity, so that the airbag is inflated and expanded, further absorbing the impact energy for buffering; S2: When the shell is hit from the outside and tends to topple, the ball slides into the inside of the slide groove and contacts the first protrusion, forcing the first protrusion to slide downward, the movement of the first protrusion drives the movement of the first connecting rod, the movement of the first connecting rod drives the movement of the second connecting rod, the movement of the second connecting rod drives the movement of the second protrusion, the movement of the second protrusion drives the movement of the moving rod, the movement of the moving rod drives the movement of the third connecting rod, the movement of the third connecting rod drives the movement of the limiting rod, so that the limiting rod slides out of the inside of the support plate, the elastic potential energy is released by the torsion spring to rotate the rotating shaft, the rotation of the rotating shaft drives the support plate to rotate and open, so as to support the shell and prevent the shell from collapsing; S3: When the support plate needs to be retracted, the support plate is rotated to one side of the top cover. The outer wall of the support plate contacts the inclined surface of the limit rod, forcing the limit rod to slide into the top cover. The movement of the limit rod drives the movement of the third connecting rod. The third connecting rod squeezes the spring to deform the spring to store elastic potential energy, and the elastic potential energy is released by the spring to make the limit rod embedded in the interior of the support plate, so that the support plate can be retracted and continued to be used.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention provides a buffer component. When the shell is subjected to external impact, the energy generated by the impact is first absorbed and dissipated by the damper, thereby reducing the impact on the shell. When the damper is displaced by a certain impact energy, it contacts the surface of the airbag, further absorbs the impact energy through the airbag, and has a certain dispersion effect on the impact energy. The use of the damper and the airbag together helps to maintain the structural stability of the shell and prevent deformation or damage caused by impact. It not only improves the service life of the plastic shell control shell, but also protects the electronic components inside the shell.

[0015] 2. The present invention provides a support assembly. When the shell falls over, the limit assembly first releases the limit on the support plate. Then, the torsion spring releases the elastic potential energy to rotate the rotating shaft. The rotation of the rotating shaft drives the support plate to rotate, so that the support plate unfolds to support the shell. This can not only reduce the possibility of the shell falling over, but also slow down the falling speed of the shell when the shell starts to fall over, reduce the impact force, and protect the integrity of the shell and the internal electronic components.

[0016] 3. The present invention sets a limit assembly. When the shell falls over, the ball slides in the slide groove, the ball contacts the first protrusion and presses the first protrusion into the base. The movement of the first protrusion drives the movement of the first connecting rod, the movement of the first connecting rod drives the movement of the second connecting rod, the movement of the second connecting rod drives the movement of the second protrusion, the movement of the second protrusion drives the moving rod to one side, the movement of the moving rod drives the movement of the third connecting rod, the movement of the third connecting rod drives the movement of the limit rod, so that the limit rod slides out from the inside of the support plate, which is convenient for the support plate to unfold and support.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, in an embodiment of the present invention, a collision-proof and buffering plastic shell control housing comprises a housing 1, a buffer assembly is arranged inside the housing 1, a top cover 2 is installed on the top of the housing 1 through bolts 25, a base 3 is fixedly installed on the bottom of the housing 1, and a supporting assembly is arranged on the outer wall of the housing 1; The buffer assembly includes a damper 4 and an airbag 7 arranged inside the housing 1. The damper 4 and the airbag 7 are evenly distributed, and each damper 4 and airbag 7 are correspondingly arranged.

[0021] When the shell 1 is subjected to external impact, the energy generated by the impact is first absorbed and dissipated by the damper 4, thereby reducing the impact on the shell 1. When the damper 4 is displaced by a certain impact energy, it contacts the surface of the airbag 7, and further absorbs the impact energy through the airbag 7, and has a certain dispersion effect on the impact energy. The use of the damper 4 and the airbag 7 together helps to maintain the structural stability of the shell 1 and prevent deformation or damage caused by impact, which not only improves the service life of the plastic shell control shell 1, but also protects the electronic components inside the shell 1.

[0022] like Figure 8As shown, a bladder body 8 is fixedly installed inside the airbag 7, a pressure block 9 is fixedly connected to one side of the bladder body 8, both sides of the inside of the bladder body 8 are connected to an air cavity 10, the air cavity 10 is opened inside the airbag 7, and the end of the air cavity 10 away from the bladder body 8 is connected to the inner cavity of the airbag 7.

[0023] When the airbag 7 is impacted, the surface will deform to a certain extent. The deformation of the airbag 7 causes the dynamic pressure block 9 to move inward, squeezing the gas inside the bladder body 8 into the interior of the airbag 7 from the air cavity 10, causing the air inside the airbag 7 to expand and absorb the impact energy, which helps to reduce the impact of the impact on the plastic shell control housing 1 and its internal components, thereby reducing the risk of damage.

[0024] like Figures 1 to 5 As shown, the support assembly includes a support plate 19 arranged on the outer wall of the shell 1, and two support plates 19 are provided. Both support plates 19 are rotatably installed inside the top cover 2 through a rotating shaft 21. A torsion spring 24 is installed on the outer wall of the rotating shaft 21, and a limiting assembly is arranged between the support plate 19 and the top cover 2.

[0025] Two sets of support plates 19 are provided on the four sides of the housing 1; When the shell 1 falls over, the limit assembly is used to release the limit on the support plate 19, and then the torsion spring 24 releases the elastic potential energy to rotate the rotating shaft 21. The rotation of the rotating shaft 21 drives the support plate 19 to rotate, so that the support plate 19 unfolds to support the shell 1, which not only reduces the possibility of the shell 1 falling over, but also slows down the falling speed of the shell 1 when the shell 1 starts to fall over, reduces the impact force, and protects the integrity of the shell 1 and the internal electronic components.

[0026] like Figures 2 to 6 As shown, the limit assembly includes a limit rod 5 arranged inside the top cover 2, one end of the limit rod 5 is fixedly connected to the third connecting rod 17, one side of the third connecting rod 17 is provided with a spring 18, one end of the third connecting rod 17 is fixedly installed with a moving rod 6, the top of the moving rod 6 is provided with a second protrusion 16, the second protrusion 16 is fixedly installed on the bottom end of the second connecting rod 15, the second connecting rod 15 is slidably installed inside the top cover 2, the bottom end of the second connecting rod 15 is fixedly installed with a first connecting rod 14, one end of the first connecting rod 14 away from the second connecting rod 15 is fixedly connected with a first protrusion 13, the first protrusion 13 is embedded in the inside of the slide groove 12, the slide groove 12 is opened inside the base 3, and the inside of the slide groove 12 is provided with a ball 11.

[0027] When the shell 1 tips over, the ball 11 slides in the inside of the slide groove 12, and the ball 11 contacts the first protrusion 13 to press the first protrusion 13 into the inside of the base 3. The movement of the first protrusion 13 drives the movement of the first connecting rod 14, and the movement of the first connecting rod 14 drives the movement of the second connecting rod 15. The movement of the second connecting rod 15 drives the movement of the second protrusion 16. The movement of the second protrusion 16 drives the moving rod 6 to move to one side. The movement of the moving rod 6 drives the movement of the third connecting rod 17. The movement of the third connecting rod 17 drives the movement of the limit rod 5, so that the limit rod 5 slides out from the inside of the support plate 19, which is convenient for the support plate 19 to unfold and support.

[0028] The top end of the moving rod 6 is inclined; When the ball 11 slides in the slide groove 12 to move the first protrusion 13 downward, the second protrusion 16 moves downward to contact the top of the moving rod 6, forcing the third connecting rod 17 to move so that the limiting rod 5 slides out of the supporting plate 19; When the support plate 19 is retracted into the top cover 2 after use, one end of the moving rod 6 contacts the bottom end of the second protrusion 16 to squeeze the second protrusion 16 to move upward, so that the first protrusion 13 slides into the interior of the slide groove 12 and resets, which is convenient for subsequent use.

[0029] like Figure 2 and Figure 3 As shown, the slide slot 12 is arranged at an angle.

[0030] When the housing 1 is in a horizontal position, the ball 11 is located at the lower end of the chute 12; When the housing 1 is tilted, the ball 11 slides into the interior of the slide groove 12 , thereby triggering the support plate 19 to open for support.

[0031] like Figure 2 and Figure 3 As shown, the slide grooves 12 are evenly distributed in a circular array.

[0032] When the shell 1 is tilted at multiple angles, the ball 11 can slide into the slide groove 12 at the corresponding position, thereby triggering the support plate 19 to open for support. When the plastic shell control shell 1 is impacted or hit in multiple directions and topples over, the support plate 19 on this side opens to support it, thereby improving the adaptability and comprehensiveness of the support for the shell 1.

[0033] like Figure 5 and Figure 6 As shown, a support pad 20 is fixedly connected to the bottom end of the support plate 19 .

[0034] Rubber has excellent anti-slip and wear-resistant properties. When the support plate 19 is opened for support, it contacts the ground or table through the support pad 20, increasing the friction between the two and minimizing the possibility of the support plate 19 sliding or tilting during the support process, thereby ensuring the stability of the entire support structure.

[0035] like Figure 4 and Figure 5 As shown, a limiting block 22 is fixedly installed on the outer wall of the rotating shaft 21 , and the limiting block 22 is slidably installed inside the limiting groove 23 .

[0036] When the support plate 19 rotates outward to expand for support, the rotation shaft 21 rotates to drive the limit block 22 to slide inside the limit groove 23. The limit groove 23 limits the sliding range of the limit block 22, thereby limiting the expansion angle of the support plate 19 to prevent the shell 1 from tilting excessively during the tipping process, thereby avoiding the shell 1 from collapsing due to loss of balance, helping to ensure the stability of the shell 1 and reducing the safety risks caused by tipping.

[0037] like Figure 5 and Figure 6 As shown, one side of the limiting rod 5 is arranged tilted.

[0038] The support plate 19 has a slide groove 12 inside for the limit rod 5 to be inserted into; When the support plate 19 needs to be retracted after being unfolded, the support plate 19 is rotated to one side of the top cover 2, and the outer wall of the support plate 19 contacts the inclined surface of the limit rod 5, forcing the limit rod 5 to slide into the top cover 2. The movement of the limit rod 5 drives the movement of the third connecting rod 17, and the third connecting rod 17 squeezes the spring 18 to deform and store elastic potential energy. When the slide groove 12 inside the support plate 19 moves to one end of the limit rod 5, the elastic potential energy is released by the spring 18 to make the limit rod 5 embedded in the inside of the support plate 19, thereby limiting the support plate 19 for subsequent use.

[0039] A method for using a collision-proof and buffering plastic shell control housing comprises the following steps: S1: When the housing 1 is hit by an external impact, the energy generated by the impact is first absorbed and dissipated by the damper 4. When the damper 4 is displaced by a certain impact energy, it contacts the surface of the airbag 7, and the impact energy is further absorbed by the airbag 7. When the airbag 7 is hit, the surface will deform to a certain extent. The deformation of the airbag 7 presses the dynamic pressure block 9 to move inward, squeezing the gas inside the capsule 8 into the air cavity 10 inside the airbag 7, so that the air inside the airbag 7 is inflated and further absorbs the impact energy for buffering; S2: When the shell 1 is hit by an external impact and tends to topple, the ball 11 slides into the inside of the slide groove 12 and contacts the first protrusion 13, forcing the first protrusion 13 to slide downward, and the movement of the first protrusion 13 drives the movement of the first connecting rod 14, and the movement of the first connecting rod 14 drives the movement of the second connecting rod 15, and the movement of the second connecting rod 15 drives the movement of the second protrusion 16, and the movement of the second protrusion 16 drives the movement of the moving rod 6, and the movement of the moving rod 6 drives the movement of the third connecting rod 17, and the movement of the third connecting rod 17 drives the movement of the limiting rod 5, so that the limiting rod 5 slides out of the inside of the support plate 19, and the elastic potential energy is released by the torsion spring 24 to rotate the rotating shaft 21, and the rotation of the rotating shaft 21 drives the support plate 19 to rotate and open, so as to support the shell 1 and prevent the shell 1 from collapsing; S3: When the support plate 19 needs to be retracted, the support plate 19 is rotated to one side of the top cover 2. The outer wall of the support plate 19 contacts the inclined surface of the limit rod 5, forcing the limit rod 5 to slide into the top cover 2. The movement of the limit rod 5 drives the movement of the third connecting rod 17. The third connecting rod 17 squeezes the spring 18 to deform and store elastic potential energy. The elastic potential energy is released by the spring 18 to make the limit rod 5 embedded in the interior of the support plate 19, and the support plate 19 is retracted for continued use.
