AI Technical Summary
In the prior art, the coupling of the windshield device is difficult to repair, especially when there is a bridge cable and an end-of-vehicle shock absorber between the angle windshield of the vehicle and the coupling, which increases the complexity and difficulty of maintenance.
A windshield device is designed, wherein the windshield is integratedly mounted on the first support and is connected to the second support through a detached attachment of the hook and the trough, and the relative position is limited by a locking member. When a hook is needed, the first support can be removed from the second support simply by removing the locking piece, simplifying the overhaul process.
Through this design, the difficulty and time of the coupling maintenance is significantly reduced, and compared with the prior art, the method of directly installing the windshield on the vehicle body can achieve a simpler and faster disassembly process.

The first support 3 and the second support 2 can be made of materials such as steel structures or aluminum alloy profiles that meet the use strength, and are of course not limited to the materials described herein.
[0033] One of the first support 3 and the second support 2 is provided with a hook, and the other is provided with a hanging groove, and the hook and the hanging groove cooperate to be detachably hung; the first support 3 can be provided with a hook, and the second support 2 is provided with a hanging groove, and of course the second support 2 can also be provided with a hanging groove 21, and the first support 3 is provided with a hook 31. This article takes the example of the first support 3 being provided with a hook and the second support 2 being provided with a hanging groove to continue to introduce the technical solution and technical effect.
[0034] The embodiment of the present application further includes a locking member, which is used to lock or unlock the first support 3 and the second support 2 that are hooked and matched. In this article, the locking member includes a fixing plate 5, and the fixing plate 5 is provided with two through holes, respectively, for the bolts or screws fixed to the first support 3 and the bolts or screws fixed to the second support 2. Of course, the locking member can also be in other forms, such as a pin or a locking wire.
[0035] In the embodiment of the present application, the windshield 1 is integratedly installed on the first support 3, and the first support 3 is then hung on the second support 2 fixed to the vehicle body, and the relative positions of the first support 3 and the second support 2 are limited by a locking member. In this way, when the coupler needs to be repaired, it is only necessary to remove the locking member to remove the first support 3 from the second support 2. Compared with the prior art of directly installing the windshield 1 on the vehicle body, the disassembly is simple and quick.
[0036] In a specific embodiment, the first support 3 has two transverse walls on the side away from the second support 2, the two transverse walls form an open slot, and the two side walls of the windshield 1 are respectively fixed to the two transverse walls. Figure 3The windshield 1 includes two side walls 11 and a curved section 12 connected between the two side walls 11. The first support 3 includes two transverse walls 32. The two side walls 11 of the windshield 1 are partially inserted into the opening groove formed by the two transverse walls 32, and the two side walls 11 are fixedly connected to the transverse walls on the corresponding sides. The two side walls 11 can be fixedly connected to the transverse walls 32 by bolts 4. The connection structure is simple and has good sealing performance.
[0037] The upward side wall of the windshield 1 may be provided with ventilation holes.
[0038] In order to improve the supporting strength of the windshield 1 , the windshield device further comprises a rubber block 6 , which is located on the side of the windshield 1 away from the corresponding side transverse wall. The side wall of the windshield 1 , the rubber block 6 and the transverse wall are fixedly connected by bolts.
[0039] Each side wall of the windshield 1 has a plurality of rubber blocks 6, which are arranged at intervals along the length direction of the windshield 1, and a predetermined distance is provided between adjacent rubber blocks 6. In this way, the weight and use strength of the windshield device can be taken into account, and the weight is as low as possible while meeting the use strength.
[0040] In a specific example, the windshield device also includes a clamping plate 7, and each rubber block 6 is located between the clamping plate 7 and the side wall of the windshield 1. Bolts simultaneously pass through and fix corresponding positions connecting the clamping plate 7, the rubber block 6 and the side wall and the transverse wall of the windshield 1.
[0041] In order to facilitate the separation of the first support 3 and the second support 2 in the windshield device and to reduce the labor intensity of the operator as much as possible, the windshield device also includes an ejection device for driving the first support 3 to move upward to disengage the hook from the hanging groove. In a specific embodiment, the ejection device includes a screw 8 extending axially in the vertical direction, the screw 8 is threadedly connected to the second support 2, and one end of the screw 8 can abut against the first support 3. When the screw 8 is rotated, the screw 8 can move toward the first support 3 and abut against the first support 3 to apply an upward force to the first support 3. Under the action of the ejection force of the screw 8, the first support 3 gradually moves away from the second support 2, and finally the hook of the first support 3 is disengaged from the hanging groove to achieve the separation of the first support 3 and the second support 2.
[0042] In a specific example, a notch 22 is provided at the lower end of the second support 2, and the screw rod 8 is at least partially located in the notch 22. In this way, the screw rod 8 can occupy as little space as possible outside the windshield device.
