Description

[Corrected under Rule 26, 18.02.2016] GLASS GAUGE FOR DETERMINING INSTALLED POSITION OF FIXTURE OF AUTOMOBILE GLASS ASSEMBLY
This application claims the benefit of priority to Chinese Patent Application No. 201420846431.5 titled “GLASS GAUGE FOR DETERMING INSTALLED POSITION OF FIXTURE OF AUTOMOBILE GLASS ASSEMBLY” , filed with the Chinese State Intellectual Property Office on December 26, 2014, the entire disclosure of which is incorporated herein by reference.
FIELD
The present application relates to a glass gauge for determining an installed position of a fixture of an automobile glass assembly.
BACKGROUND
An automobile glass assembly gauge is configured to simulate a body of an automobile, measure various dimensions of the automobile glass assembly after being installed in the body of the automobile, and evaluate whether the dimension of the glass assembly meets the design criteria based on the measured values. Furthermore, the various measured values reflect a situation of fitting between an assembled window body and a metal sheet of the body of the automobile and sub-components adjacent to the window body.
During measuring the glass assembly by the glass assembly gauge, it is required to fully insert a fixture on the automobile glass assembly into a fixing hole, so as to simulate a state that the glass assembly is fully embedded in the body of the automobile. However, in some cases, due to design error of a product, machining error of the glass fixture or the like, in the case that the glass assembly is fixed on the gauge, the glass fixture is not fully inserted into the fixing hole. In an existing glass gauge, since the fixing hole is fully covered, it is impossible to visually check whether the glass fixture is fully inserted into the fixing hole, therefore, the various values of the glass assembly measured by the glass gauge are not reliable. More seriously, in the case that the glass assembly has been installed on an automobile, but the glass fixture cannot be fully inserted into the fixing hole, when the  automobile travels at a high speed, there is a risk that the glass may be separated from the body of the automobile, which may poses a significant danger to both the automobile and person.
SUMMARY
In view of the defects in the conventional technology, an object of the present application is to provide an automobile glass assembly gauge which is capable of easily determining whether a glass fixture is fully inserted into a fixing hole and reaches a proper position.
The technical solution adopted by the present application to solve the technical problems is as follows. A glass gauge for determining an installed position of a fixture of an automobile glass assembly is provided, which includes a glass gauge frame and a fixing device including a fixing hole in the glass gauge frame, where a sensor is installed in the fixing hole and is connected with a determining device and a prompting device in sequence.
Further, the number of the fixing holes is one to four.
Preferably, the number of the fixing holes is three, and the three fixing holes are distributed on the glass gauge frame in a triangular shape. By means of the three fixing holes distributed in the triangular shape, a better fixing of the glass assembly is achieved.
Further, the prompting device is an indicating lamp and/or an audible prompting device
Further, the fixing hole is a caliper fixing hole. A glass assembly to be tested may be mechanically engaged to the caliper fixing hole through a fixture having a claw, so that the glass assembly is fixed on the glass gauge.
Further, a tightness adjusting device is installed in the caliper fixing hole. The size of the caliper fixing hole may be correspondingly adjusted by the tightness adjusting device, thereby facilitating assembly and disassembly of the glass assembly on the glass gauge.
Further, the sensor is a photoelectric sensor and/or a pressure sensor.
The photoelectric sensor includes a sensor signal transmitting end and a sensor signal receiving end, and the sensor signal transmitting end and the sensor signal receiving  end are respectively installed on inner walls of the caliper fixing hole at positions horizontally opposite to each other； the installed positions of the sensor signal transmitting end and the sensor signal receiving end of the photoelectric sensor in the caliper fixing hole are calculated by the formula:
b-a≤H≤b,
where H is a distance between a top end of the caliper fixing hole and the installed positions of the sensor signal transmitting end and the sensor signal receiving end of the photoelectric sensor in the caliper fixing hole, a is a distance between a claw of the glass fixture and a encapsulation surface of the glass assembly, and b is an overall length of the glass fixture.

The distance H between the top end of the caliper fixing hole and the installed positions of the sensor signal transmitting end and the sensor signal receiving end of the photoelectric sensor in the caliper fixing hole should be understood as that when the photoelectric sensor is in operation, the distance from light between the transmitting end and the receiving end to the top end of the caliper fixing hole is also H, that is, the distance between a trigger position of the photoelectric sensor and the top end of the caliper fixing hole is H.
The pressure sensor includes two installation ends, and the two installation ends are respectively installed on inner walls at two sides of the caliper fixing hole at positions horizontally opposite to each other； or the pressure sensor includes one installation end which is installed on an inner wall at one side of the caliper fixing hole, and the other end of the pressure sensor extends horizontally towards an inner wall of the caliper fixing hole opposite to the inner wall on which the installation end is installed, and at least extends across a central position of the caliper fixing hole.
The installed position of the installation end of the pressure sensor in the caliper fixing hole is calculated by the following formula:
b-a≤H≤b,
where H is a distance between the installed position of the installation end of the pressure sensor in the caliper fixing hole and a top end of the caliper fixing hole, a is a distance between a claw of the glass fixture and a encapsulation surface of the glass assembly, and b is an overall length of the glass fixture.
Preferably, the installed position of the installation end of the pressure sensor in the caliper fixing hole is calculated by the formula:
H＝b-a/2.
The distance H between the installed position of the pressure sensor in the caliper fixing hole and the top end of the caliper fixing hole should be understood as that in the case that the pressure sensor is fixed on the inner wall of the caliper fixing hole through the installation end, the distance between a sensing surface of the pressure sensor and the top end of the caliper fixing hole is H, that is, the distance between a trigger position of the pressure sensor and the top end of the caliper fixing hole is H.
Further, the sensor is installed on the bottom or an inner wall of the caliper fixing hole.
Further, the installed position of the sensor in the caliper fixing hole is calculated by the formula:
b-a≤H≤b,
where H is a distance between the installed position of the sensor in the caliper fixing hole and a top end of the caliper fixing hole, a is a distance between a claw of the glass fixture and a encapsulation surface of the glass assembly, and b is an overall length of the glass fixture.
Preferably, the installed position of the sensor in the caliper fixing hole is calculated by the formula:
H＝b-a/2.
The distance H between the installed position of the sensor in the caliper fixing hole and the top end of the caliper fixing hole should be under stood as that the distance between a trigger position of the sensor and the top end of the caliper fixing hole is also H.
Further, the fixing device further includes a glass pressing device, and the glass pressing device includes a body and a free end extending out from the body, and the fixing hole has a shape that matches the shape of the glass fixture. Since the glass pressing device exerts a pressure in a direction perpendicular to a plane of the glass, thus achieving the fixation of the glass assembly in a vertical direction. Furthermore, the fixing hole has a shape that matches the shape of the glass fixture, thus achieving the fixation of the glass assembly in a horizontal direction. The fixing hole having a shape that matches the shape of the glass fixture should be understood as that the profile of a cross-section of the fixing hole matches the profile of a cross-section of the glass fixture, and the width between two opposite inner walls in the cross-section of the fixing hole matches the width of the cross-section of the glass fixture thereby achieving the purpose of fixing the glass assembly in the horizontal direction in the case that the glass fixture has been inserted into the fixing hole.
Further, the sensor is a photoelectric sensor and/or a pressure sensor.
Further, the sensor is installed at the bottom of the fixing hole.
By adopting the present application, the following positive effects are achieved. The sensor inside the fixing hole senses the position for the glass fixture to be inserted into the fixing hole, the determining device connected with the sensor determines whether the glass fixture reaches a proper position in the fixing hole, and the determining device sends a prompting signal through the prompting device, thereby the technician can easily determine whether the glass assembly is properly installed on the glass gauge.

DETAILED DESCRIPTION
Hereinafter, a structure according to embodiments of the present application will be further described in conjunction with drawings.
First embodiment
As shown in Figures 1 and 2, a glass gauge for determining an installed position of a fixture of an automobile glass assembly is provided, which includes a glass gauge frame 1 and a fixing device. The fixing device includes a fixing hole 2 on the glass gauge frame. A sensor is installed in the fixing hole and is connected with a determining device and a prompting device in sequence. Particularly, a glass plate 10 of the glass assembly and a rubber coating 8 on the glass assembly are also presented.
Specifically, as shown in Figure 3, the fixing hole 2 is a caliper fixing hole 21. In the case that a glass fixture 6 of the glass assembly has a claw 61, the claw 61 may be mechanically fixed to the caliper fixing hole 21 in a snap-fit manner. The number of the caliper fixing holes 21 is equal to the number of the glass fixtures 6 having the claw, which generally is one to four. Preferably, the number of the caliper fixing holes 21 is three, and the caliper fixing holes 21 are distributed on the glass gauge frame 1 in a triangular shape.
A tightness adjusting device may be arranged on the caliper fixing hole 21 for adjusting the tightness of the caliper fixing hole 21, so as to facilitate assembly and disassembly of the glass assembly on the glass gauge. The tightness adjusting device is not specifically defined in the present application, and the tightness adjusting device may be a  clamp which is configured to adjust the tightness and is clamped on a sidewall of the fixing hole, or may be a bolt which is configured to adjust the tightness and passes through two sidewalls of the caliper fixing hole 21.
The sensor may be a photoelectric sensor. The photoelectric sensor includes a sensor signal transmitting end 311 and a sensor signal receiving end 312. The sensor signal transmitting end 311 and the sensor signal receiving end 312 are respectively installed on inner walls of the caliper fixing hole at positions horizontally opposite to each other.
As shown in Figure 7, the positions of the sensor signal transmitting end and the sensor signal receiving end of the photoelectric sensor in the caliper fixing hole are calculated by the following formula:
b-a≤H≤b,
preferably, H＝b-a/2,
where H is a distance between a top end of the caliper fixing hole and the installed positions of the sensor signal transmitting end and the sensor signal receiving end of the photoelectric sensor in the caliper fixing hole 21, a is a distance between the claw 61 of the glass fixture and the encapsulation glass surface 81, b is an overall length of the glass fixture 6.Specifically, the glass fixture 6 may be a component in cooperation with the caliper fixing hole such as a pin or a snap. The distance H between a top end of the caliper fixing hole and installed positions of the sensor signal transmitting end and the sensor signal receiving end of the photoelectric sensor in the caliper fixing hole 21 should be under stood as that when the photoelectric sensor is in operation, the distance from light between the transmitting end and the receiving end to the top end of the caliper fixing hole is also at a level of H.
The prompting device 4 may be an indicating lamp or an audible prompting device and preferably is installed above the glass gauge frame 1 or beside the caliper fixing hole 21, and each prompting device 4 is corresponding to one or multiple respective caliper fixing hole 21.
To install a glass assembly to be tested on a glass gauge, first, the caliper fixing hole 21 can be tightened by the tightness adjusting device, and then, the glass fixture 6 is inserted into the caliper fixing hole 21. In the case that the glass fixture 6 has been fully inserted, the glass fixture 6 is trapped between the transmitting end 311 and the receiving end 312, and  since the receiving end 312 cannot receive an optical signal, the determining device 7 outputs a high/low level. In the case that the glass fixture 6 is not fully inserted, since the transmitting end 311 and the receiving end 312 are not shielded, the receiving end 312 receives an optical signal, the state remains, and the determining device 7 outputs a low/high level. Such signal is used to control the prompting device 4 whether to send a prompt or not.
Second embodiment
As shown in Figures 1 and 2, a glass gauge for determining an installed position of a fixture of an automobile glass assembly is provided, which includes a glass gauge frame 1 and a fixing device. The fixing device includes a fixing hole 2 in the glass gauge frame. A sensor is installed in the fixing hole and is connected with a determining device and a prompting device in sequence. Particularly, a glass panel 10 of the glass assembly and a rubber coating 8 on the glass assembly are also presented.
Specifically, as shown in Figures 4 to 6, the fixing hole 2 is a caliper fixing hole 21. In the case that a glass fixture 6 of the glass assembly has a claw 61, the claw 61 may be mechanically fixed to the caliper fixing hole 21 in a snap-fit manner. The number of the caliper fixing holes 21 is equal to the number of the glass fixtures 6 having the claw, which generally is one to four. Preferably, the number of the caliper fixing holes 21 is three, and the caliper fixing holes 21 are distributed on the glass gauge frame 1 in a triangular shape.
The sensor may be a pressure sensor 32. The pressure sensor 32 may include two installation ends 321 which are respectively horizontally fixed on inner walls of the caliper fixing hole 21at two sides opposite to each other, as shown in Figure 4. The pressure sensor 32 also may include one installation end 321 fixed on an inner wall at one side of the caliper fixing hole 21, and the other end of the pressure sensor 32 extends horizontally towards an inner wall of the caliper fixing hole 21 opposite to the inner wall on which the installation end 321 is fixed, thus forming a cantilever structure, as shown in Figure 5. The pressure sensor 32 also may be fixed at a central position of the bottom of the caliper fixing hole 21, as shown in Figure 6.
As shown in Figure 7, the position of the installation end of the pressure sensor 32 in the caliper fixing hole is calculated by the following formula:
b-a≤H≤b,
preferably, H＝b-a/2,
where H is a distance between a predetermined installed position of the installation end of the pressure sensor 32 in the caliper fixing hole 21 and a top end of the caliper fixing hole, a is a distance between the claw 61 of the glass fixture and the encapsulation glass surface 81, b is an overall length of the glass fixture 6. Specifically, the glass fixture 6 may be a component in cooperation with the fixing device, such as a pin or a snap. The distance H between the predetermined installed position of the pressure sensor 32 in the caliper fixing hole 21 and the top end of the caliper fixing hole should be under stood as that in the case that the pressure sensor 32 is fixed on the inner wall of the caliper fixing hole through the installation end, the distance between a sensing surface or a top surface of the pressure sensor and the top end of the caliper fixing hole is H, that is, the distance between a trigger position of the pressure sensor and the top end of the caliper fixing hole is H.
The prompting device 4 may be an indicating lamp or an audible prompting device and preferably is installed above the glass gauge frame 1 or beside the caliper fixing hole 21, and each prompting device 4 is corresponding to one or multiple respective caliper fixing hole 21.
To install a glass assembly to be tested on a glass gauge, the glass fixture 6 is inserted into the caliper fixing hole 21. In the case that the glass fixture 6 has been fully inserted, the top of the glass fixture 6 is pressed on the sensing surface of the pressure sensor 32, and due to a variation in pressure, the determining device 7 outputs a high/low level. In the case that the glass fixture 6 is not fully inserted, since there is no variation in the pressure on the sensing surface of the pressure sensor 32, the state remains and the determining device 7 outputs a low/high level. This signal is used to control the prompting device 4 whether to send a prompt or not.
Third embodiment
As shown in Figures 8 and 9, a glass gauge for determining an installed position of a fixture of an automobile glass assembly is provided, which includes a glass gauge frame and a fixing device. The fixing device includes a fixing hole 22 on the glass gauge frame. A sensor is installed in the fixing hole 22 and is connected with a determining device 7 and a prompting device 4 in sequence. Particularly, a glass plate 10 of the glass assembly is also presented.
The fixing device further includes a glass pressing device 9. The fixing hole 22 has a shape that matches the shape of the glass fixture 63. The number of the glass pressing device 9 may be one, or there may be multiple glass pressing devices 9. The glass pressing device 9 includes a body and a free end 91 extending out from the body. In the case that the glass fixture 63 of the glass assembly has been inserted into the fixing hole 22, the free end 91 of the glass pressing device 9 is moved to a position above the glass assembly and exerts a pressure on the glass assembly in a direction perpendicular to a plane of the glass, thereby fixing the glass on the glass gauge. In the present application, the glass fixture 63 is not specifically defined, and the glass fixture 63 may be a part of an integrally injection-molded encapsulation surface of the glass assembly, or may be a fixture having an end that is coated by a encapsulation surface of the glass assembly. The fixing hole having a shape that matches the shape of the glass fixture should be understood as that the profile of a cross-section of the fixing hole matches the profile of a cross-section of the glass fixture, and the width between two opposite inner walls in the cross-section matches the width of the cross-section of the glass fixture, thus achieving the purpose of fixing the glass assembly in the horizontal direction in the case that the glass fixture has been inserted into the fixing hole.
The number of the fixing holes 22 is equal to the number of the glass fixtures 63, which generally is one to four. Preferably, the number of the fixing holes 22 is three, and the fixing holes 22 are distributed on the glass gauge frame 1 in a triangular shape.
The prompting device 4 may be an audible prompting device or an indicating light and is preferably installed above the glass gauge frame 1 or beside the fixing hole 22, and each audible prompting device or indicating lamp is corresponding to one or multiple respective fixing hole.
The sensor may be installed on the bottom of the fixing hole.
The sensor may be a photoelectric sensor 33 and/or a pressure sensor 34.
In the case that the sensor is the photoelectric sensor 33, the transmitting end and the receiving end of the photoelectric sensor 33 are both installed on the bottom of the fixing hole 22. To install the glass assembly to be tested on the glass gauge, the glass fixture 63 is inserted into the fixing hole 22, and the glass pressing device 9 exerts a pressure on the glass assembly in a direction perpendicular to a plane of the glass, thus fixing the glass on the glass gauge. The transmitting end of the photoelectric sensor 33 transmits a signal, the signal is  returned to the receiving end after being refracted at the top of the glass fixture 63, and the determining device 7 determines whether the distance between the top of the glass fixture 63 and the bottom of the fixing hole 22 meets the requirement on the full insertion. In the case that the distance meets the requirement on the full insertion, the determining device 7 outputs a high/low level, and the signal is used to control the audible prompting device or the indicating lamp whether to emit a sound or light or not.
In the case that the sensor is the pressure sensor 34, the pressure sensor 34 is installed on the bottom of the fixing hole 22. To install the glass assembly to be tested on the glass gauge, the glass fixture 63 is inserted into the fixing hole 22, and the glass pressing device 9 exerts a pressure on the glass assembly in a direction perpendicular to a plane of the glass, thus fixing the glass on the glass gauge. In the case that the glass fixture 63 has been fully inserted, the top of the glass fixture 63 is pressed on the pressure sensor 34, and due to the variation in pressure, the determining device 7 outputs a high/low level. In the case that the glass fixture 63 is not fully inserted, since there is no variation in the pressure on the pressure sensor 34, the state remains and the determining device 7 outputs a low/high level. Such signal is used to control the audible prompting device 4 whether to emit a sound or not. 
A glass gauge according to the embodiment of the present application is described in detail in the above description. However, the present application is not limited by the context of the embodiments described above. Any improvements, equivalent modifications and substitutions made according to the technical essential are deemed to fall into the scope of protection of the present application.
