The current windshield height is adjustable. However, the current windshield adjustment mechanism uses a sliding groove and bolts for adjustment, and requires adjustment to both the left and right sides separately. This is inconvenient during adjustment and can result in the windshield becoming misaligned. Utility Model Content

[0003] To facilitate user adjustment of the windshield, this application provides a windshield assembly.

[0004] The windshield assembly provided in this application adopts the following technical solution: A windshield assembly includes a front bracket, a windshield, a windshield mounting plate, an adjustment knob, and a reset member. The front bracket is connected to a vehicle frame. The windshield mounting plate is slidably connected to the front bracket, with its sliding direction parallel to its length. The windshield is connected to the side of the windshield mounting plate away from the front bracket. The adjustment knob is rotatably connected to the windshield mounting plate, with its rotation axis perpendicular to the sliding direction of the windshield mounting plate. The front bracket has a connecting groove into which the adjustment knob is embedded. The connecting groove has several limiting slots on its wall, spaced apart along the sliding direction of the windshield mounting plate. These limiting slots allow the adjustment knob to be embedded to achieve a fixed connection between the windshield mounting plate and the front bracket. The reset member is connected between the adjustment knob and the windshield mounting plate, causing the adjustment knob to tend to embed into the limiting slots.

[0005] By adopting the above technical solution, the windshield is connected to the windshield mounting plate. When adjustment is needed, the adjustment knob is rotated to disengage from the limiting slot, and the windshield mounting plate is pulled to slide, causing the adjustment knob to slide along the connecting groove. After moving to the designated position, the adjustment knob is released, and the adjustment knob is embedded into the limiting slot under the action of the spring force of the reset component, realizing the fixed connection between the front bracket and the windshield mounting plate, which makes it convenient for users to adjust the relative height of the windshield.

Then, by pulling the windshield mounting plate and the adjustment rod together, the relative height of the windshield can be adjusted, improving the convenience of windshield adjustment.

[0012] Preferably, a first anti-slip strip is connected to the side of the first protrusion away from the second protrusion, and a second anti-slip strip is connected to the side of the second protrusion away from the first protrusion.

[0013] By adopting the above technical solution, the friction between the first and second protrusions and the operator's fingers is increased, reducing the possibility of the first or second protrusions detaching from the fingers during the adjustment process and improving the reliability of windshield adjustment.

[0014] Preferably, the adjusting rod is equipped with an indicator.

[0015] By adopting the above technical solution, the connecting rod is equipped with an indicator mark, which makes it easy for users to understand the position and adjustment status of the adjusting rod, thereby achieving more precise adjustment of the relative height of the windshield.

[0016] Preferably, it also includes a second wear-resistant bushing, the adjusting rod is provided with a second sliding groove, the second wear-resistant bushing is connected to the windshield mounting plate, the second wear-resistant bushing is embedded in the second sliding groove, and the side wall of the second wear-resistant bushing is in contact with the groove wall of the second sliding groove.

[0017] By adopting the above technical solution, the second wear-resistant bushing is embedded in the second sliding groove, which guides the sliding of the adjusting rod, reduces the possibility of the adjusting rod deviating during the sliding process, and improves the reliability of the windshield.

[0018] Preferably, it also includes a second fixing bolt. The windshield is provided with a plurality of third connecting holes, which are divided into two groups.

The light-shielding plate 22 is located on the side of the main body 21 near the lower end of the front support 1. A positioning strip 221 is fixedly connected to the surface of the light-shielding plate 22 away from the main body 21. There are two positioning strips 221, which are symmetrically distributed along the width direction of the main body 21. The positioning strips 221 are flush with the surface of the light-shielding plate 22 near the front support 1. The windshield 3 is fixedly connected to the surface of the main body 21 and the light-shielding plate 22 away from the front support 1, and the lower end of the windshield 3 abuts against the positioning strip 221. The main body 21 has four second fixing holes 2111, which are divided into two groups. The two groups of second fixing holes 2111 are symmetrically distributed along the width direction of the main body 21. The two second fixing holes 2111 in the same group are spaced apart along the length direction of the main body 21. The light shield 22 has six third fixing holes 222, which are divided into two groups. The two groups of third fixing holes 222 correspond to the two groups of second fixing holes 2111 respectively. One third fixing hole 222 in the same group is connected to the second fixing hole 2111 on the side of the same group closest to the light shield 22. The other two third fixing holes 222 in the same group are spaced apart along the width direction of the main body 21. The windshield 3 has ten third connecting holes 31, which are divided into two groups. The two groups of third connecting holes 31 correspond to the two groups of second fixing holes 2111 and third fixing holes 222 respectively. The second fixing bolt 74 passes through the third connecting hole 31 and is threadedly connected to the second fixing hole 2111 or the third fixing hole 222. The third connecting hole 31 has a third groove 32 at the end of the hole wall away from the main body 21. The third groove 32 is used for the head of the second fixing bolt 74 to be inserted.

[0041] The implementation principle of a windshield assembly in this application embodiment is as follows: When it is necessary to adjust the height of the windshield 3, two fingers press the first protrusion 421 and the second protrusion 2110 respectively, causing the first protrusion 421 and the second protrusion 2110 to move closer to each other. The adjusting rod 42 slides, and the connecting plate 422 drives the connecting column 416 to rotate around the rotation axis of the adjusting knob 41, causing the adjusting knob 41 to rotate, causing the locking block 412 to rotate and disengage from the limiting slot. When the second wear-resistant bushing 44 on the side away from the first protrusion 421 abuts against the groove wall at one end of the second sliding groove 424 along the sliding direction of the adjusting rod 42, the two parallel side walls of the locking block 412 are flush with the groove wall of the connecting groove 11.

[0042] Pull the windshield mounting plate 2 and the adjusting rod 42 to slide. The height of the windshield 3 can be determined by the indicator mark 425 passing through the adjusting rod 42. After adjusting the outer wall, release the first protrusion 421. Under the action of the spring force of the reset member 43, the first protrusion 421 and the second protrusion 2110 move away from each other. The adjusting knob 41 rotates, which drives the locking block 412 to rotate and embed into the limiting slot 12, so as to realize the fixed connection between the windshield mounting plate 2 and the front bracket 1.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
