Description

Technical Field

[0001] This utility model relates to the field of recreational vehicle technology, specifically to an electric window for a motorhome. Background Technology

[0002] In the RV industry, a motorhome is a mobile vehicle that integrates the functions of a "house" and a "vehicle," combining the dual attributes of living and transportation. As a special type of recreational vehicle, it is equipped with living facilities such as bedrooms, kitchens, and bathrooms, providing users with basic living spaces for living, cooking, and resting. Externally, the windows, which can be moved freely based on the vehicle chassis, serve as an important link between the interior living and the outdoor scenery. While ensuring lighting and ventilation, they also take into account heat insulation and sealing performance, allowing the interior space to be both bright and scenic, while maintaining a comfortable temperature and quiet environment.

[0003] In the current RV market, most windows still rely on traditional manual operation. Due to the compact design of RVs, which are multifunctional and integrated, users have to frequently bend over and awkwardly push and pull the windows. Whenever they want to capture the fleeting beauty of the mountains and fields while parked, they have to interrupt this immersive experience by repeatedly adjusting the windows, which ruins the leisurely mood of enjoying the scenery. On a bumpy journey, manually opening the windows is even more challenging. The shaking of the vehicle makes the operation difficult, not only making it difficult to bring in fresh natural air, but also potentially damaging the window's seal due to uneven force. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an electric window for RVs, which offers advantages such as lighting and ventilation, as well as heat insulation. It solves the problem that most existing vehicle windows still rely on traditional manual opening and closing methods. Due to the compact design of RVs with multiple functions, users have to frequently bend over and awkwardly push and pull the windows. On rough and bumpy journeys, manually opening the window is even more challenging, as the swaying of the vehicle body makes operation difficult. This not only makes it difficult to introduce fresh natural air, but may also damage the window's sealing performance due to uneven force.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A motorhome electric window includes an outer frame, an inner window frame fixedly connected to the inner wall surface of the outer frame, a first window slidably connected to one side surface of the outer frame, a second window slidably connected to one side surface of the outer frame, and an adjustment mechanism provided on one side surface of the second window; the adjustment mechanism includes a lifting device and a fixing device, the lifting device pushing the fixing device and the window and positioning them.

[0009] Preferably, the fixing device includes a bottom slide, which is fixedly connected to one side surface of the first window. A sliding groove is formed on one side of the bottom slide, and an electric push rod is fixedly connected to one inner wall surface of the sliding groove. A slider is fixedly connected to one side surface of the electric push rod, and an insert is fixedly connected to the side surface of the slider away from the electric push rod. A side slide is slidably connected to one side surface of the bottom slide, and a locking hole is formed on one side surface of the side slide. A dustproof strip is formed on one side surface of the sliding groove.

[0010] Preferably, the lifting device includes a rack, the rack is fixedly connected to one side surface of the first window, a gear is meshed with one side surface of the rack, a motor is fixed to one side of the gear, and a guide rod is provided on one side surface of the bottom slide.

[0014] Preferably, the outer wall size of the insert block matches the inner wall size of the locking hole, and the bottom slide is distributed parallel to the first and second windows.

[0015] Compared with the prior art, the present invention provides an electric window for RVs, which has the following advantages:

[0016] 1. The motorhome's electric windows, through the precise meshing of gears and racks in the lifting device, enable accurate control of window raising and lowering. Users can adjust the windows to any opening degree at will. The motor drive replaces traditional manual operation, greatly reducing the difficulty of use. At the same time, the design of the guide rod and side slide provides a stable guiding effect for window raising and lowering, reducing the shaking and jamming of the windows during the raising and lowering process, and ensuring smooth and stable window operation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 It includes an outer frame 1, an inner window frame 2 fixedly connected to the inner wall surface of the outer frame 1, a first window 3 slidably connected to one side surface of the outer frame 1, a second window 4 slidably connected to one side surface of the outer frame 1, and an adjustment mechanism 5 provided on one side surface of the second window 4, the adjustment mechanism 5 including a lifting device and a fixing device.

[0026] In this embodiment, the fixing device includes a bottom slide 501, which is fixedly connected to one side surface of the first window 3. A sliding groove 502 is provided on one side of the bottom slide 501. An electric push rod 503 is fixedly connected to one inner wall surface of the sliding groove 502. A slider 504 is fixedly connected to one side surface of the electric push rod 503. An insert block 505 is fixedly connected to the side surface of the slider 504 away from the electric push rod 503. A side slide strip 506 is slidably connected to one side surface of the bottom slide 501. A locking hole 507 is provided on one side surface of the side slide strip 506. A dustproof strip 508 is provided on one side surface of the sliding groove 502. With the configuration of the bottom slide 501, sliding groove 502, electric push rod 503, slider 504, insert block 505, side slide bar 506, and locking hole 507, during use, the electric push rod 503 receives a control signal and begins linear telescopic movement. With stable thrust, it drives the slider 504 to slide precisely within the sliding groove 502 opened in the bottom slide 501. Since the slider 504 is fixedly connected to the insert block 505, the displacement of the slider 504 synchronously pushes the insert block 505 to move horizontally until the insert block 505 is completely embedded in the locking hole 507 of the side slide bar 506, firmly locking the first window 3 to the side slide bar 506. The two symmetrically distributed fixing devices work synchronously to form a stable multi-support fixing structure, so that the window can remain motionless under complex road conditions, effectively improving the stability of the mechanism and reducing the probability of failure.

[0027] Furthermore, the lifting device includes a rack 509, which is fixedly connected to one side surface of the first window 3. A gear 510 is meshed with one side surface of the rack 509, and a motor 511 is fixed to one side of the gear 510. A guide rod 512 is provided on one side surface of the bottom slide 501. Through the arrangement of the rack 509, gear 510, motor 511, and guide rod 512, in use, the motor 511 is powered on and starts, driving the gear 510 connected to it to rotate. Since the gear 510 meshes with the rack 509 fixed to the side surface of the first window 3, the rotational motion of the gear 510 is converted into the linear motion of the rack 509, thereby driving the first window 3 to move vertically up and down along the guide rod 512. The guide rod 512 not only provides a precise movement trajectory for the window but also effectively disperses external forces, preventing the window from shifting or shaking during lifting and lowering, thus improving safety.

[0028] Furthermore, the outer wall dimensions of the first window 3 and the second window 4 are the same and they are arranged in parallel. The inner window frame 2 has two identical sets, with two identical frames in each set. Through the arrangement of the inner window frame 2, the two sets of symmetrically arranged inner window frames 2 are positioned and supported during use, effectively improving the sealing performance. At the same time, the identical size of the first window 3 and the second window 4 effectively saves on overall costs.

[0029] Furthermore, the electric push rod 503, slider 504, and insert block 505 are provided in two identical sizes and are symmetrically distributed along the inner wall surface of the sliding groove 502. Similarly, the inner wall surface of the side slide bar 506 is provided in two identical sizes and is symmetrically distributed along the central axis of the first window 3. Through the arrangement of the electric push rod 503, slider 504, and insert block 505, during use, the electric push rod 503 pushes the slider 504 to slide linearly along the inner wall of the sliding groove 502, causing the insert block 505 to move towards the side slide bar 506. Since the inner wall of the side slide bar 506 also has two symmetrically arranged locking holes 507, precisely corresponding to the position of the insert block 505, when the insert block 505 is fully inserted into the locking hole 507, a multi-point symmetrical locking structure is formed, greatly improving stability and sealing.

[0030] In addition, the vertical central axis of the guide rod 512 is parallel to the vertical central axis of the rack 509, and the outer wall dimension of the dustproof strip 508 matches the inner wall dimension of the sliding groove 502. With the guide rod 512 in place, during use, when the motor 511 drives the gear 510 to rotate, the rack 509 moves linearly under the action of the gear 510. At this time, the guide rod 512 provides synchronous sliding guidance for the window, ensuring that the window maintains precise vertical displacement during lifting and lowering, avoiding tilting or jamming caused by lateral forces.

[0031] It is worth noting that the outer wall dimensions of the insert 505 match the inner wall dimensions of the locking hole 507, and the bottom slide 501 is parallel to the first window 3 and the second window 4. Through the arrangement of the bottom slide 501, the first window 3, and the second window 4, during use, the bottom slide 501 remains parallel to the first window 3 and the second window 4, providing a stable mounting reference surface for the components of the fixing device. Simultaneously, it ensures that the insert 505 is always perpendicularly aligned with the locking hole 507 during movement, avoiding locking failure due to angular deviation and reducing the mechanism's error rate.

[0032] When in use, the motorhome's electric window operates with the lifting and fixing devices working in tandem. When the user needs to adjust the window position, the adjusting mechanism 5 activates, the motor 511 starts, and drives the gear 510 to rotate. Since the gear 510 and rack 509 are meshed, the first window 3 is driven to smoothly rise and fall vertically along the guide rod 512. When the first window 3 reaches the target position, the fixing device activates, the electric push rod 503 starts, and pushes the slider 504 to slide along the track within the sliding groove 502 of the bottom slide 501, thereby driving the insert block. 505 moves towards the side slide bar 506 until the insert 505 is inserted into the locking hole 507, firmly connecting the first window 3 to the side slide bar 506, thus locking the position of the first window 3. At this time, the two symmetrically distributed fixing devices work simultaneously to ensure that the window remains stable under driving bumps or wind. The dustproof strip 508 fits tightly against the inner wall of the sliding groove 502, effectively blocking dust, rainwater, etc. from entering, ensuring the normal operation of the adjustment mechanism 5 and extending its service life. The motor 511 is model YE2-132S-4. This completes the use process of a motorhome electric window.
