Description

Technical Field

[0001] The utility model relates to the technical field of vehicle windows, in particular to an outward-pushing motorcycle window. Background Art

[0002] The outward-sliding windows of railway locomotives typically feature a hinged upper edge and a lower edge that opens and closes. Operators typically manually push or pull the window to open and close. This manual push or pull operation is time-consuming and labor-intensive when the window is heavy. Furthermore, conventional outward-sliding windows lack an angle-locking function, preventing them from being held in the open position at any angle. Furthermore, these conventional outward-sliding windows can be opened from the outside, posing a safety hazard. Uneven force application during operation can easily damage the window. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an outward-pushing motorcycle window which is more labor-saving to operate, simple and reliable in structure, can be locked in any position and has good safety.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An outward-pushing motorcycle window comprises a frame and a window, wherein the upper end of the window is rotatably connected to the frame, and a transmission mechanism with a self-locking function is installed on the frame, and a support mechanism is connected to the transmission mechanism, and the support mechanism is connected to the window. The transmission mechanism is also connected to a rocking mechanism, and the rocking mechanism is rotated to drive the transmission mechanism to rotate and drive the support mechanism to move, so that the support mechanism drives the window to rotate around the connection point between it and the frame.

[0006] As a further improvement of the above technical solution:

[0007] The transmission mechanism includes a gear shaft and two screw pairs. The gear shaft is movably connected to the frame in the transverse direction through a bearing. The two screw pairs are perpendicular to the gear shaft, and the ends of the screws are provided with second gears that mesh with the corresponding first gears on the gear shaft. The nut seats on the two screw pairs are respectively connected to one of the support mechanisms.

[0008] The support mechanism includes two hinged seats and a support rod, one hinged seat is fixedly connected to the nut seat, the other hinged seat is fixedly connected to the window body, and both ends of the support rod are respectively hinged to the two hinged seats.

[0009] The rocking mechanism includes a crank, a connecting shaft and a third gear. The crank is detachably connected to the connecting shaft. The connecting shaft is movably connected to the frame through a bearing. The third gear is fixed on the connecting shaft and meshes with the corresponding first gear on the gear shaft.

[0010] A sealing ring is provided at the connection between the connecting shaft and the frame.

[0011] The frame is provided with a sealing strip, and the window is pressed against the sealing strip when closed.

[0012] When the window is closed, the angle A between the lead screw and the support rod is 3° to 5°.

[0013] The first gear, the second gear and the third gear are all bevel gears.

[0014] The frame is a flange structure.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. The outward-pushing motorcycle window of the present invention is equipped with a transmission mechanism, a rocking mechanism, and a supporting mechanism with a self-locking function on the frame. The rocking mechanism can be driven by the transmission mechanism, and the support mechanism drives the window to rotate around the connection point through the transmission mechanism. The window can be opened and closed. The operation is convenient and the window can be opened with power. When the window is thick and heavy, the opening efficiency can be significantly improved.

[0017] 2. The structure of the utility model is simple and reliable. During the opening and closing process, the transmission mechanism evenly applies force to the window, avoiding the situation where the window is damaged due to uneven force.

[0018] 3. Through the self-locking function of the transmission mechanism, the window can be locked at any angle within the rotation range, and can also prevent it from being operated, opened or closed from the outside, avoiding misoperation. It will not be opened or closed by external force during driving, which improves driving safety and protects the life and property of people in the car. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 6 As shown, the outward-pushing motorcycle window of this embodiment includes a frame 1 and a window 2. The upper end of the window 2 is rotatably connected to the frame 1. The frame 1 is equipped with a transmission mechanism 3 with a self-locking function. The transmission mechanism 3 is connected to a support mechanism 4, which is connected to the window 2. The transmission mechanism 3 is also connected to a rocking mechanism 5. By rotating the rocking mechanism 5, the transmission mechanism 3 is driven to rotate and move the support mechanism 4, so that the support mechanism 4 drives the window 2 to rotate about its connection point with the frame 1. During use, the rocking mechanism 5 is manually shaken, and the transmission mechanism 3 transmits force, causing the support mechanism 4 to rotate the window 2 about the hinge point, thereby opening and closing the window 2. The structure is simple and easy to operate. The self-locking function of the transmission mechanism 3 can lock the window 2 at any angle within the rotation range. Furthermore, the support mechanism 4 connects the transmission mechanism 3 and the window 2, making it impossible to push or pull the window 2 from the outside, thereby improving safety.

[0029] In this embodiment, the transmission mechanism 3 includes a gear shaft 31 and two lead screw pairs 32. The gear shaft 31 is movably connected to the frame 1 in the transverse direction via a bearing. The two lead screw pairs 32 are perpendicular to the gear shaft 31. The ends of the lead screws 321 are provided with second gears 3211 that mesh with corresponding first gears 311 on the gear shaft 31. The nut seats 322 on the two lead screw pairs 32 are each connected to a support mechanism 4. In this structure, the lead screw pair 32 refers to a helical transmission component composed of a lead screw and a nut. Its primary function is to convert rotational motion into linear motion. The gear shaft 31 meshes with the second gear 3211 on the lead screw 321 through the first gear 311. When the lead screw pair 32 rotates, it drives the lead screw 321 to rotate, causing the nut seat 322 to move along the lead screw 321, thereby causing the support mechanism 4 to retract or extend the window 2. During use, after the window 2 is adjusted to the user's desired angle, the window angle can be fixed by a self-locking function. The simple and reliable structure makes the vehicle window function more user-friendly.

[0030] In this embodiment, the support mechanism 4 comprises two hinged seats 41 and a support rod 42. One hinged seat 41 is fixedly connected to the nut seat 322, while the other hinged seat 41 is fixedly connected to the window 2. The ends of the support rod 42 are respectively hingedly connected to the two hinged seats 41. This simple and reliable structure, combined with the self-locking function of the transmission mechanism 3, prevents the window 2 from opening or closing due to external forces during driving, thereby improving driving safety and protecting the lives and property of the vehicle occupants.

[0031] In this embodiment, the crank mechanism 5 includes a crank handle 51, a connecting shaft 52, and a third gear 53. The crank handle 51 is detachably connected to the connecting shaft 52, and the connecting shaft 52 is movably connected to the frame 1 via a bearing. The third gear 53 is fixed to the connecting shaft 52 and meshes with the corresponding first gear 311 on the gear shaft 31. In this structure, rotating the crank handle 51 drives the third gear to rotate, driving the transmission mechanism to operate, and the operation of opening or closing the window is simple and convenient. Preferably, the crank handle 51 can be a detachable crank handle, which can be removed from the connecting shaft 52 when the window is not in use or is restricted in use, so that the crank handle 51 acts as a safety lock key, meeting special usage scenarios, greatly improving the safety performance of the window, and effectively protecting the life and property of people in the car.

[0032] In this embodiment, a sealing ring 6 is provided at the connection between the connecting shaft 52 and the frame 1. A sealing strip is provided on the frame 1. When the window 2 is closed, it is pressed against the sealing strip. When the window 2 is closed, the angle A between the lead screw 31 and the support rod 42 is 3° to 5°. In this structure, the provision of the sealing ring 6 and the sealing strip ensures a sealing effect after the window 2 is closed. The angle A changes with the rotation of the support rod 42. When the window 2 is closed, the angle A remains between 3° and 5°, maintaining a relatively small angle between the lead screw 31 and the support rod 42. This provides pre-load on the sealing strip, ensuring a sealing effect and achieving noise reduction and sound insulation, while also ensuring that the window 2 can be opened normally.

[0033] In this embodiment, the first gear 311, the second gear 3211 and the third gear 53 are all configured as bevel gears. In this structure, the bevel gears have high torque transmission capacity, compact structure and good self-locking performance.

[0034] In this embodiment, the frame 1 is configured as a flange structure, which is convenient for installation.

[0035] In this embodiment, the upper end of the window 2 is hinged to the frame 1 through a hinge, the gear shaft 31 in the transmission mechanism 3 is fixedly connected to the frame 1 through a bearing seat, and the screw pair 32 is fixedly installed on the frame 1 through a support seat.

Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the content of the present invention and are based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
