[0018] The following will be combined with specific embodiments and attached Figure 1-3 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0019] The utility model provides a new forklift cab rear window structure (such as Figure 1As shown), it includes glass 1, non-metallic hinge 2, locking mechanism, supporting mechanism, and sealing assembly 5. In this embodiment, tempered glass can be used for glass 1 to improve its structural strength and reduce the probability of breakage. Non-metallic hinge 2 is a mature technology product on the existing market, with high rotation matching accuracy, neat appearance and low price. One end of the two non-metallic hinges 2 is fixedly arranged on the cab frame 7 on the upper part of the rear window of the cab. The non-metallic hinge 2 is fixedly connected to the cab frame 7 by bolts. The upper part of the glass 1 is fixedly connected to the other end of the two non-metallic hinges 2. Specifically, a second passage corresponding to the countersunk hole 21 on the non-metallic hinge 2 is opened on the glass 1. The fixed connection between the glass and the non-metallic hinge is realized by a combination of bolts and nuts. By rotating the two non-metallic hinges 2, the glass can be swung backward at a large angle relative to the cab. The glass can be opened at a large angle, which can improve the ventilation effect inside the cab and enable the driver to The rear window field of view is increased, and further, the glass can be opened at a large angle, which is convenient for the driver to use the rear window to escape in special circumstances, thereby improving the driving safety of the forklift; the glass is opened by swinging from bottom to top using a hinge, so that even if it is opened on rainy days, there is no large amount of rain entering the interior of the cab through the window, thereby improving the convenience of use; the glass 1 can be sealed on the rear window of the cab, thereby providing a basic guarantee for the sealing of the rear window, the sealing component is arranged on the periphery of the glass 1, and the locking mechanism is used to realize the locking and fixing of the lower part of the glass 1 and the lower part of the rear window of the cab, and the glass 1 is locked and fixed by the locking mechanism, the sealing component 5 is tightly fitted with the cab frame around the rear window of the cab, and after the sealing component 5 is tightly fitted with the cab frame, the sealing of the rear window is realized, thereby playing a better wind and dust blocking effect in bad weather; the supporting mechanism can realize stable support of the glass 1 after opening.

[0020] On the basis of the above embodiment, in order to improve the field of vision of the glass 1, the rear window structure also includes a wiper 6, and the wiper 6 is arranged at the rear of the glass 1. The wiper can be used to clean the dust within the corresponding range on the glass 1, thereby ensuring the cleanliness of the glass.

[0021] On the basis of the above implementation, the specific implementation method of the locking mechanism is as follows: the locking mechanism is a rotary clamping handle, the door buckle of the rotary clamping handle is fixedly arranged on the lower front side of the rear window of the cab, and the rotary handle 31 of the rotary clamping handle is fixedly arranged on the lower front side of the glass 1. When the glass 1 is closed, the lower part of the rotary handle 31 is rotated to make its lower part snap into the corresponding door buckle, thereby realizing the locking connection between the glass 1 and the lower part of the rear window. Compared with the existing plastic connecting lock, the rotary clamping handle has a high structural strength and is not easy to be damaged, thereby reducing the maintenance frequency.

[0022] On the basis of the above embodiment, the specific implementation of the support mechanism is as follows: the support mechanism includes two gas springs 41, which are commonly used support components in the existing market, so the detailed structure and working principle of the gas springs 41 are not described in detail. The two gas springs 41 are distributed on the upper rear side of the glass 1. The telescopic end of the gas spring 41 is hingedly connected to a fixed bracket 42. A first through hole corresponding to the fixing hole on the fixed bracket 42 is opened on the glass 1. A fixing bolt passes through the fixing hole and the first through hole on the fixed bracket 42 from front to back in sequence. The fixing bracket 42 is fixedly installed on the glass 1 by rotating the fixing nut 43 at the rear of the fixing bolt. The fixed end of the gas spring 41 is hingedly connected to a fixing seat 45, and the fixing seat 45 is fixedly arranged on the side wall of the rear window of the cab. In actual application, the gas spring 41 performs telescopic movement following the swing of the glass 1. At the same time, when the opening angle of the glass 1 is kept at the maximum, the two gas springs 1 can achieve stable support of the glass 1, so that the glass 1 can be kept open at a large angle for a long time. Furthermore, in order to improve the protection of the glass 1 , a rubber pad 44 is sleeved on the fixing bolt, and the rubber pad 44 is located between the fixing nut 43 and the glass 1 .

[0023] Based on the above embodiments, the specific implementation of the sealing component is as follows: the sealing component 5 is a U-shaped side bubble sealing strip, the U-shaped groove of the U-shaped side bubble sealing strip is snapped onto the edge of the glass 1, and the U-shaped side bubble sealing strip is directly snapped onto the periphery of the glass 1 by snapping, and its connection stability is high, so as to facilitate the long-term maintenance of the airtightness of the window.

[0024] In the present utility model, "upper", "lower", "front", "back", "left" and "right" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0025] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0026] The above description in combination with the accompanying drawings has detailed the preferred implementation modes and embodiments of the utility model, but the utility model is not limited to the above implementation modes and embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
