Description

Technical Field

[0001] This utility model relates to the field of insulated glass, specifically to a pressure balancing device for insulated glass. Background Technology

[0002] With rapid economic development, the application of glass is becoming increasingly widespread. Users adjust the settings according to different application environments, leading to the emergence of various types of glass for different regions and styles. Insulating glass is one such application. Insulating glass is a new type of building material that offers excellent heat insulation, sound insulation, aesthetic appeal, and reduces the building's weight. It typically consists of two panes of glass and a central sealing connector to meet better usage requirements. However, the central sealing connector is difficult to balance during later use. When the glass is subjected to external pressure, the inability to distribute and balance the pressure can cause excessive local stress, leading to breakage and significantly reducing overall safety.

[0003] According to patent 202322056192.5, a pressure balancing device for insulating glass, it includes a lower glass, an upper glass, and a central sealing connector. The central sealing connector connects the lower and upper glass and includes an outer frame and an inner frame. A buffer structure connects the outer and inner frames. The buffer structure includes a mounting groove, a support rod, a spring, and a sliding sleeve. The mounting groove is located on the inner wall of the outer frame. The support rod is fixedly connected between the two end walls of the mounting groove. The spring is sleeved around the support rod, and the sliding sleeve is slidably sleeved around the support rod. This invention, by setting a buffer structure, allows the glass to quickly distribute the force to the central sealing connector after being subjected to external force. The buffer structure then allows the central sealing connector to achieve buffering, thereby better achieving pressure balance and preventing excessive localized stress on the glass, which could lead to breakage.

[0004] However, in practice, traditional insulated glass pressure balancing devices typically use frame-type buffer components to alleviate the pressure on the upper and lower panes. However, this frame-type buffer is limited to pressure buffering only around the edges of the glass. When the upper and lower panes encounter pressure from their central area, the pressure distribution between the edges and the center becomes uneven. This uneven pressure distribution prevents effective dispersion and balance, leading to excessive stress in localized areas and increasing the risk of glass breakage due to stress concentration. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and meet practical needs by providing a pressure balancing device for insulated glass units. This addresses the problem that current traditional pressure balancing devices typically employ frame-type buffer components to alleviate pressure on the upper and lower glass panes. However, these frame-type buffer components are limited to pressure buffering only around the edges of the glass. When the upper and lower glass panes encounter pressure from their central areas, the pressure distribution between the edge and central areas becomes uneven. This uneven pressure distribution prevents effective dispersion and balancing of pressure, leading to excessive stress in localized areas and increasing the risk of glass breakage due to stress concentration.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a pressure balancing device for insulating glass is designed, including an upper glass and a lower glass. A first fixed cylinder is provided between the upper glass and the lower glass. A second fixed cylinder is passed through both the upper and lower ends of the first fixed cylinder. A first damping block is fixed to the end of the second fixed cylinder located inside the first fixed cylinder. A first spring is fixed between the two first damping blocks. The upper glass and the lower glass are fixed to the end of the second fixed cylinder away from the first fixed cylinder. A pressure balancing component is provided outside the second fixed cylinder.

[0007] Preferably, the pressure balancing assembly includes multiple fixing plates, an airbag cushion, a fixing ring, a third fixing cylinder, a fourth fixing cylinder, a second damping block, and a second spring.

[0008] Preferably, a plurality of the third fixing cylinders are respectively installed at the four bottom corners of the upper glass and the four top corners of the lower glass, and a fourth fixing cylinder passes through between the corresponding upper and lower third fixing cylinders. A second damping block is fixed to one end of the fourth fixing cylinder located inside the third fixing cylinder.

[0009] Preferably, a second spring is fixed to the end of the second damping block away from the fourth fixed cylinder, and a third fixed cylinder is fixed to the end of the second spring away from the second damping block.

[0010] Preferably, a fixing ring is installed on the outside of the third fixing cylinder, a fixing strip is fixed to one end of the fixing ring, and a second fixing cylinder is fixed to the end of the fixing strip away from the fixing ring.

[0011] Preferably, the surface of the fixing strip is equipped with multiple airbags, and the ends of the multiple airbags away from the fixing strip are attached to the upper and lower glass.

[0012] Preferably, the upper and lower glass are fitted with a frame, and each of the four sides of the frame has a cavity, into which a shape memory alloy rod is fixed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the combination of a first fixed cylinder, a second fixed cylinder, and a pressure balancing assembly, not only utilizes the first spring and the first damping block within the first fixed cylinder to buffer pressure from the center positions of the upper and lower glass panes, but also features a pressure balancing assembly on the outside of the second fixed cylinder. This assembly connects to the fixed ring via fixed plates, and the air cushions on the surfaces of the fixed plates at multiple locations provide support and buffering for different positions on the surfaces of the upper and lower glass panes. When different positions on the surfaces of the upper and lower glass panes are subjected to pressure, the multiple fixed plates will respectively drive the second and third fixed cylinders to move, simultaneously buffering pressure using the damping blocks and springs within the second and third fixed cylinders. This achieves multi-point pressure linkage buffering, balancing the pressure of the insulated glass, and solving the problem of traditional insulated glass pressure balancing devices, which typically use frame-type buffer assemblies to alleviate pressure on the upper and lower glass panes. However, such frame-type buffer assemblies are limited to pressure buffering in the perimeter areas of the glass. When the upper and lower glass panes encounter pressure from their center areas, there will be uneven pressure distribution between the edge and center areas. This uneven pressure distribution makes it impossible to effectively disperse and balance the pressure, which in turn leads to excessive stress in local areas, increasing the risk of glass breakage due to stress concentration.

[0015] 2. This utility model, through the combination of frame, cavity and shape memory alloy rod, not only protects the four sides of the insulating glass with the frame and shape memory alloy rod, but also, when the frame and shape memory alloy rod are deformed by impact, the shape memory alloy rod will self-reset, thereby driving the frame to reset, thus avoiding the impact of frame deformation on the insulating glass.

Detailed Implementation

[0020] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A pressure balancing device for insulating glass, see [link to example]. Figures 1 to 3 The system includes an upper glass 1 and a lower glass 101. A first fixing cylinder 204 is disposed between the upper glass 1 and the lower glass 101. A second fixing cylinder 208 extends through both ends of the first fixing cylinder 204. A first damping block 209 is fixed to one end of the second fixing cylinder 208 located inside the first fixing cylinder 204. A first spring 210 is fixed between the two first damping blocks 209. The upper glass 1 and the lower glass 101 are fixed to the end of the second fixing cylinder 208 away from the first fixing cylinder 204. A pressure balancing assembly is disposed outside the second fixing cylinder 208. When pressure is applied to the center position of the surfaces of the upper glass 1 and the lower glass 101, it will cause the second fixing cylinder 208 located at the center position to move. The second fixing cylinder 208 will compress the first damping block 209 and the first spring 210 inside the first fixing cylinder 204, thereby buffering the pressure at the center position of the upper glass 1 and the lower glass 101. When pressure is applied at the four corners, the third fixed cylinder 2 will compress the second spring 206 and the second damping block 207, buffering the pressure at the four corners. Simultaneously, the third fixed cylinder 2 will also move the fixed ring 202 and the fixed strip 203. The fixed strip 203 will then move the second fixed cylinder 208, which in turn will move other fixed strips 203, causing the second fixed cylinder 208 to move into the first fixed cylinder 204, compressing the first spring 210 and the first damping block 209 within the first fixed cylinder 204. Other fixed strips 203 will then move the third fixed cylinder 2 at different positions, compressing the second spring 206 and the second damping block 207, thus simultaneously buffering multiple points and balancing the pressure on the insulated glass. This solves the problem of traditional insulated glass pressure balancing devices, which typically use frame-type buffer assemblies to alleviate the pressure on the upper and lower glass layers. However, such frame-type buffer assemblies are limited to pressure buffering at the edges of the glass. When the upper and lower glass panes encounter pressure from their central region, an uneven pressure distribution occurs between the edge and central areas. This uneven pressure distribution prevents the pressure from being effectively dispersed and balanced, leading to excessive stress in localized areas and increasing the risk of the glass breaking due to stress concentration.

[0022] For details, see Figure 2 The pressure balancing assembly includes multiple fixing plates 203, an airbag cushion 205, a fixing ring 202, a third fixing cylinder 2, a fourth fixing cylinder 201, a second damping block 207, and a second spring 206.

[0023] Further, see Figure 2 Multiple third fixing cylinders 2 are respectively installed at the four bottom corners of the upper glass 1 and the four top corners of the lower glass 101. A fourth fixing cylinder 201 passes through between the corresponding upper and lower third fixing cylinders 2. A second damping block 207 is fixed at one end of the fourth fixing cylinder 201 located inside the third fixing cylinder 2.

[0024] It is worth noting that, see Figure 2 The second damping block 207 is fixed with a second spring 206 at one end away from the fourth fixed cylinder 201, and the second spring 206 is fixed with a third fixed cylinder 2 at one end away from the second damping block 207.

[0025] It is worth noting that, see Figure 2 A fixing ring 202 is installed on the outside of the third fixing cylinder 2. A fixing strip 203 is fixed to one end of the fixing ring 202, and a second fixing cylinder 208 is fixed to the end of the fixing strip 203 away from the fixing ring 202.

[0026] It is worth mentioning that, see Figure 2 Multiple airbags 205 are installed on the surface of the fixing strip 203. The ends of the multiple airbags 205 away from the fixing strip 203 are attached to the upper glass 1 and the lower glass 101. The airbags 205 on the surface of the fixing strip 203 at multiple positions can provide support and buffer at different positions on the surface of the upper glass 1 and the lower glass 101.

[0027] It is worth emphasizing that, see Figure 3 The upper glass 1 and lower glass 101 are externally fitted with a frame 3. Each of the four sides of the frame 3 has an internal cavity 301, inside which a shape memory alloy rod 302 is fixed. The frame 3 and the shape memory alloy rods reinforce the perimeter of the insulated glass unit. When the frame 3 and the shape memory alloy rods are impacted and deformed, the shape memory alloy rods self-recover due to their shape memory effect. This recovery process drives the frame 3 back to its initial state, effectively preventing the potential impact of frame 3 deformation on the structural integrity and performance of the insulated glass unit.

[0028] When a pressure balancing device is used for insulating glass, pressure is applied to the center of the surfaces of the upper glass 1 and the lower glass 101, causing the second fixed cylinder 208 located at the center to move. The second fixed cylinder 208 compresses the first damping block 209 and the first spring 210 inside the first fixed cylinder 204, thereby buffering the pressure at the center of the upper glass 1 and the lower glass 101. When pressure is applied to the four corners of the upper glass 1 and the lower glass 101, the third fixed cylinder 2 compresses the second spring 206 and the second damping block 207, buffering the pressure at the four corners. At the same time, the third fixed cylinder 2 also drives the fixed ring 202 and the fixed... When the fixed plate 203 moves, it drives the second fixed cylinder 208 to move. The second fixed cylinder 208 then drives other fixed plates 203 to move, causing the second fixed cylinder 208 to move into the first fixed cylinder 204. This compresses the first spring 210 and the first damping block 209 within the first fixed cylinder 204. Simultaneously, the other fixed plates 203 drive the third fixed cylinders 2 at different positions to move, compressing the second spring 206 and the second damping block 207. This provides simultaneous buffering at multiple points, balancing the pressure on the insulating glass unit. The frame 3 and shape memory alloy rods reinforce the perimeter of the insulating glass unit. When the frame 3 and shape memory alloy rods are impacted and deformed, the shape memory alloy rods self-recover due to their shape memory effect. This recovery process drives the frame 3 back to its initial state, effectively preventing the potential impact of frame 3 deformation on the structural integrity and performance of the insulating glass unit.
