Detailed Description
The following are preferred embodiments of the present application, and it should be noted that modifications and variations can be made by those skilled in the art without departing from the principle of the present application, and these modifications and variations are also considered as the protection scope of the present application.
Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. The terms first, second and the like in the description and in the claims and in the above-described figures are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order.
Before the technical scheme of the application is described, the technical problems in the related art are described in detail.
With the increasing demands of people on the active safety and the passive safety performance of automobiles, the demands on the safety performance of automobile glass are also increasing. For example, in addition to the early requirements for protecting the interior of a passenger (head model), standards such as (middle lapping) C-NCAP, (middle lapping) C-IASI, EURO-NCAP, ECE UN R127 and the like have newly increased requirements for protecting the exterior of a passenger from collision, and it is prescribed that the simulated head model collides with a certain position on the front windshield at a certain speed and direction from outside the car, and the head injury index (Head Injury Criterion, HIC) cannot exceed a certain prescribed value.
However, the existing automobile glass cannot simultaneously meet the requirements of a head model test, a line protection test and have enough flying stone impact resistance. For example, the front windshield in the related art is generally a laminated glass, such as a combination of 2.1+2.1, 2.3+2.3, 2.5+2.5, etc., limited by glass surface stress, and when the glass annealing stress is greater than 15MPa, the line preservation test is at a greater risk. If the mode that the stress of the glass is reduced and the glass can be annealed at a low speed after being formed by dead weight is adopted, the production efficiency and the forming precision are reduced. In addition, the low surface stress can cause the front windshield to have poor resistance to road flystones, and the glass is easy to break when being subjected to external sand and stone impact during running.
In view of this, in order to solve the above-described problems, the present application provides a glass assembly. Referring to fig. 1, fig. 1 is a schematic structural diagram of a glass assembly according to an embodiment of the application. The present embodiment provides a glass assembly 1 including a first glass 11, an interlayer 10, and a second glass 12. The first glass 11 and the second glass 12 are mounted on opposite sides of the intermediate layer 10.
Wherein the linear thermal expansion coefficient of the first glass 11 is 20×10 -7 /K-50*10 -7 K, the linear thermal expansion coefficient of the second glass 12 is 20 x 10 -7 /K-120*10 -7 K; the surface compressive stress sigma of the first glass 11 1 A surface compressive stress sigma of the second glass 12 of 2MPa to 10MPa 2 Is 2MPa-25MPa.
The glass module 1 provided in the present embodiment can be used in the field of vehicles, and functions such as protection, observation, and cooperation with other members, and the shape and structure of the glass module 1 are not limited in the present application. The glass module 1 according to the present embodiment can be applied to various fields and structures, and the present embodiment is schematically described only by applying the glass module 1 to a vehicle. However, this does not represent that the glass module 1 of the present embodiment is necessarily applied to a vehicle. In other embodiments, the present application may be applied to other structures, such as in the field of construction, machinery, and the like.

Since the first glass 11 and the second glass 12 in this embodiment are both adhered to the interlayer 10, the interlayer 10 can adhere or hold glass and glass fragments when the glass assembly 1 collides with the outside, so as to reduce the probability of glass breakage and splashing. The thickness of the intermediate layer 10 refers to the dimension of the intermediate layer 10 in the alignment direction of the intermediate layer 10 and the first glass 11 (as shown in the direction D in fig. 1).

The first glass 11 has a linear thermal expansion coefficient of 20 x 10 -7 /K-50*10 -7 The first glass 11 can not only ensure higher energy absorption and buffering capacity when impacted by blunt objects at high speed, but also reduceThe injury to people caused by severe collision can be improved, meanwhile, the capability of the first glass 11 for resisting low-energy impact of sharp objects such as flying stones and the like and not being broken is improved, and the process difficulty and the production cost can be reduced. If the linear thermal expansion coefficient of the first glass 11 is too large or too small, the surface compression stress of the first glass 11 is affected, so that the cooperation of the first glass 11 and the second glass 12 is not facilitated, the high energy absorption and buffering capacity of the first glass 11 when the first glass is impacted by a blunt object at a high speed is reduced, the injury to people caused by severe impact is increased, and the low energy impact resistance of the first glass 11 to sharp objects such as flying stones and the like is reduced without breaking, so that the glass assembly 1 cannot be ensured to meet the requirements of a head model test and a line protection test at the same time, and has enough flying stone impact resistance; but also increases the process difficulty and the production cost.
The second glass 12 has a linear thermal expansion coefficient of 20 x 10 -7 /K-120*10 -7 and/K, the second glass 12 can be ensured to have higher energy absorption and buffering capacity when being impacted by blunt objects at high speed, the injury to people caused by severe collision is reduced, the capability of the second glass 12 for resisting low-energy impact of sharp objects such as flying stones and the like and not being broken is improved, the process difficulty is reduced, and the production cost is reduced. If the linear thermal expansion coefficient of the second glass 12 is too large or too small, the surface compression stress of the second glass 12 is affected, so that the cooperation of the first glass 11 and the second glass 12 is not facilitated, the second glass 12 can have higher energy absorption and buffering capacity when being impacted by blunt objects at high speed, the injury to people caused by severe collision is increased, and meanwhile, the capacity of the second glass 12 for resisting the impact of sharp objects such as flying stones and the like with low energy and not breaking is reduced, so that the glass assembly 1 cannot be ensured to simultaneously meet the head mould test and the line protection test, and has enough flying stone impact resistance; but also increases the process difficulty and the production cost.
Alternatively, the surface compressive stress of the first glass 11 is 4MPa, or 6MPa, or 8MPa; the surface compressive stress of the second glass 12 is 4MPa, or 6MPa, or 8MPa, or 10MPa, or 12MPa, or 14MPa, or 16MPa, or 18MPa, or 20MPa, or 22MPa, or 24MPa.
The surface compression stress of the first glass 11 is 2MPa-10MPa, so that the first glass 11 can have higher energy absorption and buffering capacity when impacted by blunt objects at high speed, injury to people caused by severe collision is reduced, the capability of the first glass 11 that the first glass is resistant to low-energy impact of sharp objects such as flying stones and the like and not broken is ensured, the process difficulty is reduced, and the production cost is reduced. If the surface compressive stress of the first glass 11 is less than 2MPa, the process difficulty is increased, and the production cost is increased; if the surface compressive stress of the first glass 11 is greater than 10MPa, the first glass 11 can have lower energy absorption and buffering capacity when impacted by a blunt object at a high speed, and the injury to people caused by severe impact is increased, so that the glass assembly 1 cannot be ensured to simultaneously meet the head mould test and the line protection test, and has enough flying stone impact resistance.
Further alternatively, in one embodiment, the surface compressive stress σ of the first glass 11 1 A surface compressive stress sigma of the second glass 12 of 2MPa to 10MPa 2 Is 2MPa to 10MPa.
The surface compressive stress of the first glass 11 and the second glass 12 in the embodiment is 2MPa-10MPa, and at this time, the effect of the first glass 11 and the second glass 12 mutually matching is better, so that the energy absorption and buffering capacity of the glass assembly 1 when the glass assembly is impacted at a high speed by blunt objects can be further improved, the injury to people caused by severe collision is further reduced, and meanwhile, the capacity of the glass assembly 1 that the glass assembly is resistant to low-energy impact of sharp objects such as flying stones and the like and is not broken is further ensured, so that the glass assembly 1 simultaneously meets the head model test, the line protection test and has enough flying stone impact resistance.
First, since the first glass 11 and the second glass 12 have low linear thermal expansion coefficients and low surface compressive stresses, the energy absorption and buffering capacities of the first glass 11 and the second glass 12 when being impacted by a blunt object at a high speed are improved, injuries to people caused by severe impact are reduced, and the capacities of the first glass 11 and the second glass 12 that sharp objects such as flying stones are resisted and the sharp objects such as flying stones are not broken are improved. Further, by matching the first glass 11 and the second glass 12, the energy absorbing and buffering ability of the glass module 1 when the glass module is impacted at a high speed by a blunt object can be further improved, the injury to a person caused by a severe collision can be further reduced, and the ability of the glass module 1 to withstand a sharp object such as flying stone and not to break can be further improved.
In addition, since the two glasses in the present embodiment are respectively disposed at opposite sides of the interlayer 10, the interlayer 10 can bond or hold glass and glass fragments when the glass assembly 1 collides with the outside, so as to reduce the probability of glass breakage and splashing.
Therefore, in this embodiment, the first glass 11 and the second glass 12 have a low linear thermal expansion coefficient and a low surface compressive stress, and the two glasses are mutually matched, so that the energy absorption and buffering capability of the glass assembly 1 when being impacted by a blunt object at a high speed are improved, the injury to people caused by severe collision is reduced, and the capability of the glass assembly 1 that the glass assembly is not broken when being impacted by sharp objects such as flying stones is improved, so that the glass assembly 1 simultaneously meets the head model test, the line protection test and the sufficient flying stone impact resistance.
Alternatively, the surface compressive stress of the first glass 11 and the second glass 12 is equal.
