Description

Technical Field

[0001] This utility model relates to the field of teaching and training technology, and in particular to a quick disassembly and assembly structure for car window glass used in window breaking training. Background Technology

[0002] In practical training, students need to be taught how to break windows and perform emergency rescues. Each student must break at least one car window. After breaking, the glass needs to be replaced. Although the interior trim of the teaching vehicle has been removed, installing the glass still requires a series of operations such as alignment, locking, and adjusting the height, which takes considerable time. A class often has a dozen to several dozen students, making the overall training time very long. Consequently, in some parts of the lesson, not every student can participate, significantly reducing the teaching effectiveness.

[0003] Therefore, based on years of relevant teaching experience, the applicant designed and improved a quick-release and assembly structure for car window glass used in window breaking training, which can significantly improve the efficiency of glass replacement and reduce costs accordingly. Utility Model Content

[0012] The vertical track is a U-shaped groove track that fits the back edge of the glass.

[0013] In some embodiments, a top-pressure screw is provided on the long support rail.

[0014] In some embodiments, it further includes: a lifting assembly for adjusting the long support rail;

[0015] The lifting assembly includes: multiple tension springs whose upper ends are fixedly connected to upper stop bars and whose lower ends are fixedly connected to long support rails;

[0016] In normal operation, the tension spring pulls the glass upwards until it is in the closed window position.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0052] like Figure 1 As shown, after the interior trim on the inside of the car door is removed, the metal frame is exposed. At this time, the upper part of the metal frame of the car door, together with the upper edge of the window, blocks the glass. At the same time, the notch set on the metal frame exposes part of the lower edge of the glass. The lower edge of the glass is connected to the electric lifting mechanism by bolts to realize the lifting and adjustment. This is the conventional operation mode of the car window glass.

[0053] In this state, when replacing the glass (which has already been broken), the bolts connecting the glass to the lifting mechanism need to be removed, and then the broken glass needs to be removed. Next, adjust the electric lifting mechanism to the half-raised position, insert the glass, lock it, and then raise the entire unit to the desired height to close the window, thus conducting a window-breaking training exercise. After the glass is broken, repeat the above replacement operation.

[0054] The overall process is quite cumbersome and time-consuming.

[0055] Example 1.

[0056] See Figures 1-6 The quick-assembly and disassembly structure for vehicle window glass used in window breaking training includes: an upper arc segment 1 and a vertical segment 2 that are hinged together after the upper structure of the vehicle window is cut, and a vertical track 3 that is fixedly assembled on the rear side of the glass groove and faces forward.

[0057] The front end of the upper arc segment 1 is hinged to the cutting point in front of the car window.

[0058] Vertical segment 2 swings upward and opens, forming Figure 4 The state shown.

[0059] The upper arc segment 1 and the vertical segment 2 swing upward and open, forming Figure 5 The state shown.

[0060] Optionally, it also includes: a long support rail 4 that is positioned directly below the window glass to provide lower support.

[0061] It should be noted that the long support rail 4 is optional; alternatively, the long support rail 4 can be omitted, and the original electric lifting mechanism can be adjusted to a fixed form to support the lower end of the glass.

[0062] When setting the long support rail 4, it is preferable to remove the original electric lifting mechanism or adjust it to a low position so as not to cause interference or influence; at this time, the long support rail 4 is fixedly installed in the metal frame of the car door to support the lower end of the glass; at the same time, the vertical rail 3 forms a partial limit on the rear side of the glass.

[0063] When in use, open the upper arc section 1 and the vertical section 2, take out the old glass from the top, and insert the new glass into the glass groove from top to bottom, along with the vertical rail 3 and the long support rail 4 (or the electric lifting mechanism fixed to the support position); then, swing to close the upper arc section 1 and the vertical section 2, and the glass replacement is completed. It is highly efficient and can be operated from both the inside and outside of the car door, without the need for complicated disassembly procedures or tools.

[0064] It is understandable that for the hinge relationship between the upper arc segment 1 and the vertical segment 2, and between the upper arc segment 1 and the front cutting point of the window, it is sufficient to use hinge parts of appropriate specifications for assembly so that it can swing open.

[0065] Preferred, such as Figure 12 , 13 As shown, the long support rail 4 is a U-shaped groove track that fits the lower edge of the glass (i.e., it is set accordingly based on the shape of the lower end of the glass); as Figure 4 , 6 As shown, the vertical track 3 is a straight U-shaped groove track that fits against the back edge of the glass.

[0066] Understandably, the inner groove of the long rail 4-clamp glass is designed to be slightly larger than the thickness of the glass for easier installation; and its length is designed to be longer than the original lifting mechanism in order to form a larger support point; in addition, original factory glass is preferred in practical training for a more realistic effect.

[0067] Preferably, a bolt is inserted inward at the rear end of the vertical section 2, and the section is detachably assembled and connected to the rear side of the vertical track 3 via the bolt.

[0068] Optionally, a groove can be provided at the rear end of vertical segment 2 to hide the bolt and prevent protrusion.

[0069] like Figure 2 , 3 As shown; in the installed state, the lower end of the vertical section 2 is locked to the vertical rail 3 by bolt assembly; during disassembly and assembly, the bolts connecting the vertical rail 3 are removed to open the vertical section 2.

[0070] It is understandable that, such as Figure 6As shown; the vertical track 3 extends downward within the glass groove and is securely assembled with the metal frame; and the rear wall of the vertical track 3 is made thicker to accommodate threads without penetrating into the interior to avoid pressing against the glass; optionally, a connecting nut (e.g., welded) is fixed to the rear wall of the vertical track 3 to facilitate bolt connection.

[0071] Furthermore, a slot is provided at the front end of the vertical section 2 to cooperate with the vertical track 3; in the closed state, part of the vertical track 3 is inserted into the slot at the front end of the vertical section 2.

[0072] It should be noted that the long support rail 4 is installed inside the metal frame of the door, and may be partially or completely concealed; it replaces the lifting mechanism to form the bottom support; such as Figure 3 As shown, some long support rails 4 can be seen through the gaps in the metal frame of the car door.

[0073] It should be noted that this design is for a teaching aid vehicle structure; although setting it to an articulated connection has a certain impact on the overall structural strength, the teaching aid vehicle is stationary and does not pose any additional danger.

[0074] Example 2.

[0075] See Figure 7 Unlike the previous embodiment, in order to expose the lower end of the glass and facilitate operations such as cleaning broken glass and internal maintenance, we have provided an opening 100.

[0076] Specifically, this embodiment includes:

[0077] An opening 100 is formed by cutting inside the upper part of the metal frame of the door, exposing the lower part of the glass and the long support rail 4; and an upper retaining strip 5 is formed by retaining part of the metal frame at the lower edge of the window.

[0078] like Figure 7 As shown, we cut an opening 100 near the top of the metal frame; thus, the lower part of the glass and the long support rail 4 can be exposed, which facilitates various operations; at the same time, part of the metal frame is retained as the upper stop bar 5 (that is, the original glass groove clamping state is retained) to ensure the stability of the window during operation.

[0079] Example 3.

[0080] See Figures 8-13 Unlike the previous embodiments, the long support rail 4 is not fixed in position but adjustable; this reduces the operational requirements for installation and allows the glass to be moved up or down without opening the upper arc section 1 and the vertical section 2.

[0081] Specifically, this embodiment includes a lifting assembly 6 for adjusting the long support rail 4.

[0082] The lifting assembly 6 includes multiple tension springs 61 with upper stop bars 5 fixedly connected at the upper end and long support rails 4 fixedly connected at the lower end.

[0083] like Figure 10 As shown; in normal operation, the tension spring 61 pulls the glass upwards until it is in the closed position; when pressed down with external force, the glass slides down to open the part, and the glass can be removed.

[0084] The spring has limited upward and downward movement; when the glass is broken and needs to be replaced, it can be taken out directly upwards; when replacing the glass, the long support rail 4 can be pressed downwards, which is very quick and convenient.

[0085] Understandably, multiple tension springs 61 are provided to ensure that the tension is relatively balanced in various places; and the overall tension of the tension springs 61 must be greater than the weight of the glass so that it can be in a stable closed window position.

[0086] Understandably, the lifting assembly 6, in conjunction with the long support rail 4, forms an adjustable bottom support; similar to a discarded, cumbersome electric lifting mechanism, it lifts the glass upwards and can quickly press it down; after pressing it down, the long support rail 4 is temporarily restricted, allowing the glass to be removed.

[0087] It should be noted that with the lifting component 6 installed, we can choose to retain the original upper structure of the window (i.e., without cutting to form a hinge, it is still a single piece), and there is no need to install the vertical track 3; the glass can be installed and removed simply by using the long support track 4 that is pressed down.

[0088] It should be noted that at this time, since the glass and the long support rail 4 are in a coordinated moving state, we may choose to strengthen the connection between the two; for example... Figures 9-13 As shown, a top-pressure screw 41 is provided on the long support rail 4 to strengthen the clamping and fixing of the glass.

[0089] It should be noted that the top pressure screw 41 is not necessary. The long support rail 4 mainly provides upward lifting force. When moving upward, the long support rail 4 supports the glass. When moving downward, the glass presses down on the long support rail 4. Generally, derailment will not occur.

[0090] In this state:

[0091] After the glass is broken, remove it from the long rail 4 (if it is broken or incomplete, it can be pulled out directly; if it has a glass film and is still in an intact state, press down a little to remove the glass).

[0092] Adjust the long support rail 4 to descend (manually pull the long support rail 4 down from the inside and insert it into the glass; or, directly insert the new glass and press the long support rail 4 down).

[0093] After installing the new glass, use the elasticity to quickly lift the long support rail 4.

[0094] This completes one glass replacement operation.

[0095] Furthermore, the lifting assembly 6 also includes a guide rod 7 to enhance the stability of the lifting process.

[0096] Correspondingly, a limiting block 42 that slides with the guide rod 7 is fixed on the outside of the long support rail 4; the upper end of the guide rod 7 is connected to the upper stop bar 5 and penetrates the limiting block 42 vertically downward.

[0097] Furthermore, the guide rod 7 is a long pin; the outer side of the upper stop bar 5 is provided with an opening block 51 for inserting the long pin; after the long pin passes through the opening block 51, it passes through the limiting block 42.

[0098] Furthermore, the lower section of the guide rod 7 is threaded, and an adjusting nut 71 is fitted after penetrating the limiting block 42; thus, the lowest position of the long support rail 4 can be controlled by adjusting the nut, avoiding excessive burden on the tension spring 61 when installing new glass.

[0099] Furthermore, the opening block 51 has a vertical slot extending outward; at the same time, a protrusion matching the vertical slot is integrally provided near the end of the guide rod 7; through the cooperation of the two, the guide rod 7 does not rotate, making it easy to operate the adjusting nut 71.

[0100] When in use, select a suitable tension spring 61 in advance and adjust the shape of the guide rod 7; the tension spring 61 drives the long support rail 4 to rise, putting the glass in the closed window position; after the glass is broken, quickly remove the glass; then, press down the long support rail 4, install the new glass, and it will automatically rise to the closed window position.

[0101] Example 4.

[0102] Unlike the previous embodiments, this embodiment takes into account the influence of the irregular shape of the bottom edge of the glass; we set the long support rail 4 as a straight groove; correspondingly, the bottom edge of the glass is a straight edge (that is, it may be different from the shape of the original glass).

[0103] It is understandable that some vehicle windows do not have a straight bottom edge. In this case, the long support rail 4 needs to be set to an irregular shape to fit the bottom edge of the glass. This is quite troublesome, especially since the bottom structure of some door windows is complex and irregular. Installation is also inconvenient (of course, the bottom of some window glass is not irregular and is straight, so there is no need to consider this).

[0104] To further accelerate the replacement efficiency, the long support rail 4 is set as a straight groove; correspondingly, the lower end of the glass has a straight edge; this further simplifies the operation.

[0105] In other words, when dealing with car windows with irregularly shaped bottoms, we no longer need to use the same form as the original factory glass. The glass shape is much simpler, with a straight bottom edge, which not only provides a larger contact surface and more contact points, but also makes installation more stable and convenient. Furthermore, even if the bottom edge is partially damaged, it will not affect normal use. At the same time, the production cost of the glass is also greatly reduced, which can significantly reduce teaching expenses. In addition, the transportation, storage, and installation processes are also much more convenient, further reducing the overall cost.

[0106] With this configuration, the long support rail 4 can be adapted to simplified vehicle window glass, significantly reducing costs and having great application value.

[0107] Of course, it is undeniable that this will create some differences from the original glass, but for window breaking training, it will not affect the trainees' operation in any way.

[0108] Example 5.

[0109] Unlike the previous embodiments, this embodiment takes into account the impact of glass replacement on the rubber strip; we have a U-shaped rubber strip 8 with an opening facing downwards clamped at the top of the upper stop 5.

[0110] Understandably, in window breaking instruction, the glass needs to be replaced frequently, which causes significant damage to the sealing strip. Therefore, we have made some improvements to the sealing strip; we have adopted a straight U-shaped rubber strip 8, which is installed on the lower inner side and can be replaced separately.

[0111] Furthermore, such as Figure 10 , 11 As shown in Figure 14, the upper inner edge (the side closest to the glass) of the U-shaped rubber strip 8 is set with an arc corner, and the lower inner edge is also set with an arc corner; this makes installation easier and reduces wear and tear.

[0112] Furthermore, adhesive is affixed to the side of the upper baffle 5 closest to the interior of the vehicle; the adhesive is used to reinforce the fixation of the U-shaped rubber strip 8.

[0113] This invention provides an installation mechanism for quickly replacing car window glass; when used in window breaking training, it can greatly reduce the time required to replace the glass, and the operation process is simpler and more efficient.
