Description

Technical Field

[0001] This utility model relates to a locking mechanism for a motorhome expansion box, belonging to the field of motorhome expansion box technology. Background Technology

[0002] RVs or campervans are fashionable products that integrate "clothing, food, housing, and transportation," realizing "living while traveling and traveling while living." RVs are equipped with a lot of furniture and appliances, and the driving safety of RVs is very important.

[0003] To ensure the smooth operation of the RV's extension box and the vehicle during travel, the extension box needs to be locked. Currently, existing RVs typically use manual pins or motor-driven self-locking methods for locking the extension box, which is labor-intensive and somewhat less secure. The purpose of this invention is to provide an RV extension box locking mechanism, which is a power control device (electric or pneumatic). The control device keeps the locking device in a locked state, preventing the extension box from sliding out when the RV encounters bumps during travel, thus ensuring the safety of the RV during travel. Utility Model Content

[0004] This application provides a locking mechanism for a motorhome expandable box, which adopts the following technical solution:

[0005] A locking mechanism for a motorhome expansion box includes a vehicle body and an expansion box. The mechanism is characterized in that a locking device fixing frame is provided at the upper and lower positions of the vehicle body corresponding to the expansion box, the locking device fixing frame is provided with a locking device, and the expansion box is provided with a lock hole corresponding to the locking device.

[0006] By adopting the above technical solution, the locking device can lock the expansion box, preventing it from sliding out when the RV encounters bumps during travel, thus ensuring the safety of the RV during travel.

[0007] Preferably, the locking device fixing bracket is provided with multiple brackets.

[0008] By adopting the above technical solution, the locking devices on the multiple locking device fixing brackets can reinforce the locking state of the expansion box, further improving the safety performance of the RV during travel.

[0009] Preferably, it also includes a power control device, a control pipeline, and a control valve. The power control device is placed inside the vehicle body, and the power control device is connected to the control valve through the control pipeline. The control valve is connected to the locking device.

[0010] By adopting the above technical solution, the locking device is controlled to be in an open or closed state through a power control device, control pipeline and control valve.

[0011] In summary, this application has the following advantages or beneficial effects:

[0012] During normal driving, the RV's extendable body is in the retracted state. The locking device is controlled by the control unit to lock the extendable body in the locked state, preventing it from sliding out when the RV encounters bumps during driving and ensuring the safety of the RV during driving.

[0019] 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.

[0020] Reference Figure 1 , 2 As shown in Figures 3, 4, and 5: A locking mechanism for a motorhome expandable enclosure includes a vehicle body 1 and an expandable enclosure 2. Multiple locking device mounting brackets 4 are provided at the upper and lower positions of the expandable enclosure 2 corresponding to the vehicle body 1. Each locking device mounting bracket 4 is equipped with a locking device 3. The expandable enclosure 2 has locking holes 8 corresponding to the locking devices 3. It also includes a power control device 5, a control pipeline 6, and a control valve 7. The power control device 5 is placed inside the vehicle body 1 and is connected to the control valve 7 via the control pipeline 6. The control valve 7 is connected to the locking device 3.

[0021] When the RV is parked and the extendable compartment 2 needs to be used, first turn off the power control device 5. The control valve 7 then pulls the locking device 3 out of the lock hole 8, putting the locking device 3 in the open position. The extendable compartment 2 slides out. In case of special circumstances where the extendable compartment control device malfunctions, the extendable compartment 2 can be manually pushed back into the vehicle body 1. When the extendable compartment 2 is fully retracted after use, first turn on the power control device 5. The control valve 7 then inserts the locking device 3 into the lock hole 8, putting the locking device 3 in the locked position. During normal RV driving, the extendable compartment 2 is in the retracted position, and the locking device 3 is locked to prevent it from sliding out when encountering bumps, thus ensuring safe driving.

[0022] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only for the purpose of helping to understand the method and core ideas of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that due to the limitations of textual expression, there are objectively infinite specific structures. For those skilled in the art, several improvements, modifications, or changes can be made without departing from the principles of this utility model, and the above technical features can also be combined in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
