[0046] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with the specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present disclosure.

[0047] Combine Figures 1 to 5As shown, this embodiment provides a RV air conditioner installation and positioning device, including: a roof panel 1, the roof panel 1 is provided with a mounting hole 3 for the RV air conditioner 2; an air conditioner 2, the air conditioner 2 includes a connecting portion 4; a positioning structure, a positioning member 5 is provided on the positioning structure, and the positioning member 5 is movably arranged on the positioning structure, and the positioning member 5 includes a first state and a second state that can be switched with each other; in the first state, the positioning member 5 can be supported on the mounting hole 3 and cooperate with the connecting portion 4 to position the air conditioner 2.

[0048] The RV air conditioner installation and positioning device of this embodiment is used for installation and positioning of the RV air conditioner 2. The positioning member 5 is installed on the installation hole 3 of the roof panel 1. The RV air conditioner 2 is positioned by the cooperation between the connecting portion 4 and the positioning member 5, which solves the problem of difficult positioning during the installation of the RV air conditioner 2. It is easy to operate and use, low in cost, and easy to promote on a large scale. At the same time, the positioning member 5 is movably arranged on the positioning structure. The positioning member 5 can be movably switched between a first state (i.e., a working state) and a second state (i.e., a non-working state), so that the components of the installation and positioning device are better integrated. There is no need to use multiple parts for separate packaging. The entire device can be packaged and placed in the packaging box of the RV air conditioner 2 product and directly transported with the RV air conditioner 2, which improves the convenience of the transportation link. It can also reduce the time for assembling and disassembling components during the installation and positioning process, thereby improving the installation efficiency of the RV air conditioner 2.

[0049] In order to set the positioning structure on the mounting hole 3 before the RV air conditioner 2 is installed and positioned, or to remove the positioning structure from the mounting hole 3 after the RV air conditioner 2 is installed and positioned, so as to prevent the positioning member 5 from interfering with subsequent installation steps of the air conditioner 2, in the second state of this embodiment, the positioning member 5 is disengaged from the mounting hole 3, and the mounting hole 3 is no longer in contact with the positioning structure, so that the positioning structure can be inserted into or removed from the mounting hole 3. The positioning structure can be removed automatically or manually.

[0050] In some embodiments, the positioning structure includes a positioning box 8, and the positioning member 5 is retractably disposed on the positioning box 8. In a first state, the positioning member 5 extends outside the positioning box 8, and in a second state, the positioning member 5 retracts into the positioning box 8. The positioning member 5 of this embodiment adopts a telescopic design. When the positioning member 5 is retracted into the positioning box 8, the overall volume is small and the structure is stable, making it very convenient for storage and portability. Furthermore, the telescopic design facilitates disassembly without damaging the structure, while also enabling multiple uses.

[0051] In some embodiments, the positioning box 8 is a rectangular parallelepiped. In the positioning structure of this embodiment, the positioning box 8 adopts a regular shape, which is very convenient for installation, carrying and storage. The positioning member 5 is retracted into the positioning box 8, which can also play a protective role and prevent accidental damage.

[0052] In some embodiments, to ensure a complete seal between the air conditioner 2 and the roof panel 1 after installation, a gasket 7 is provided on the connecting portion 4. The gasket 7 cooperates with the positioning member 5 to position the air conditioner 2. When the gasket 7 and the positioning member 5 are engaged, the air conditioner 2 reaches the predetermined installation position. If the air conditioner 2 becomes unstable or tilts after installation, it indicates that the gasket 7 and the positioning member 5 are not fully engaged, that is, the air conditioner 2 is not positioned accurately, and the position of the air conditioner 2 needs to be adjusted until the air conditioner 2 is stable and does not tilt.

[0053] In some embodiments, to ensure accurate positioning of the air conditioner 2 and allow for smooth removal of the positioning member 5 after positioning is complete, the positioning member 5 includes a first positioning portion 5.1 and a second positioning portion 5.2. In a first state, the first positioning portion 5.1 and the second positioning portion 5.2 are supported on opposite edges of the mounting hole 3. By installing the two positioning portions on opposite edges of the mounting hole 3, the air conditioner 2 and the mounting hole 3 have at least two accurate positioning reference points, thereby further ensuring more accurate positioning. Furthermore, the positioning member 5 is designed as a split piece for easy removal.

[0054] In some embodiments, to ensure the positioning preparation of the air conditioner 2, it is necessary to first ensure that the position of the positioning member 5 is accurate, and at the same time, to ensure that the positioning member 5 always maintains the accurate position during the installation and positioning process of the RV air conditioner 2. Therefore, the first positioning part 5.1 is connected to the first support part 6.1, and the first support part 6.1 is arranged inside the positioning box 8. The first support part 6.1 is configured to support the first positioning part 5.1, and support and fix the first positioning part 5.1 on the edge of the mounting hole 3; and / or, the second positioning part 5.2 is connected to the second support part 6.2, and the second support part 6.2 is arranged inside the positioning box 8. The second support part 6.2 is configured to support the second positioning part 5.2, and support and fix the second positioning part 5.2 on the edge of the opposite side of the mounting hole 3.

[0055] In some embodiments, to prevent the first positioning portion 5.1 from falling out of the positioning box 8 and maintain the integration of the first positioning portion 5.1 and the positioning box 8, when the RV air conditioner installation and positioning device includes a first support portion 6.1, the first support portion 6.1 is provided with a first extension limit block 9, which is configured to limit the maximum extension position of the first positioning portion 5.1. When the RV air conditioner installation and positioning device includes a second support portion 6.2, the second support portion 6.2 is provided with a second extension limit block 10, which is configured to limit the maximum extension position of the second positioning portion 5.2. The second extension limit block 10 also prevents the second positioning portion 5.2 from falling out of the positioning box 8.

[0056] In some embodiments, the maximum extension position of the first positioning portion 5.1 or the second positioning portion 5.2, i.e., the first state position, can be set. When the first positioning portion 5.1 or the second positioning portion 5.2 is extended, by sensing the limiting feedback of the first extension limit block 9 on the first positioning portion 5.1, or the limiting feedback of the second extension limit block 10 on the second positioning portion 5.2, it can be very convenient to determine that the first positioning portion 5.1 or the second positioning portion 5.2 has been extended into place. The staff can adjust the positioning structure to a precise positioning position without the aid of any measuring equipment, which is beneficial to the positioning and installation efficiency of the RV air conditioner 2.

[0057] In some embodiments, after the first positioning portion 5.1 or the second positioning portion 5.2 extends to the first state, in order to ensure that the positioning member 5 always maintains the accurate position and does not retreat during the installation and positioning process of the RV air conditioner 2, the first support portion 6.1 is required to provide a stable supporting force for the first positioning portion 5.1, or the second support portion 6.2 is required to provide a stable supporting force for the second positioning portion 5.2. The positioning box 8 is also provided with a first support limit block 11, which is movably installed on the positioning box 8, and the first support limit block 11 is configured to provide a limiting support for keeping the first positioning portion 5.1 in the first state; and / or, the positioning box 8 is also provided with a second support limit block 12, which is movably installed on the positioning box 8, and the second support limit block 12 is configured to provide a limiting support for keeping the second positioning portion 5.2 in the first state.

[0058] Since in the first state, the first support limit block 11 and the second support limit block 12 provide limiting support to the first support part 6.1 and the second support part 6.2 respectively, and the positioning member 5 switches between the first state and the second state by extending or retracting the positioning box 8, the support limit block and the second support limit block 12 have two positions: limiting and non-limiting.

[0059] Therefore, in this embodiment, when the RV air conditioner installation positioning device includes a first support limit block 11, a first slide groove 13 is provided on the positioning box 8, and the first support limit block 11 is movably arranged in the first slide groove 13. When the first positioning part 5.1 is in the first state, the first support limit block 11 can slide along the first slide groove 13 and be limitedly supported at the end of the first support part 6.1. When the first positioning part 5.1 needs to be switched to the second state, the first support limit block 11 slides in the opposite direction along the first slide groove 13 to avoid the retraction path of the first support part 6.1.

[0060] When the RV air conditioner installation positioning device includes a second support limit block 12, a second slide groove 14 is provided on the positioning box 8, and the second support limit block 12 is movably set in the second slide groove 14. When the second positioning part 5.2 is in the first state, the second support limit block 12 can slide along the second slide groove 14 and be limitedly supported at the end of the second support part 6.2. When the second positioning part 5.2 needs to be switched to the second state, the second support limit block 12 slides in the opposite direction along the second slide groove 14 to avoid the retraction path of the second support part 6.2.

[0061] In some embodiments, in order to improve the compactness of the components of the positioning device and control the overall volume of the positioning structure, when the RV air conditioner installation positioning device includes a first support part 6.1 and a second support part 6.2, the first support part 6.1 and the second support part 6.2 are arranged in parallel in the positioning box 8, which can not only provide positioning for the RV air conditioner 2 from relative directions, but also achieve the compactness of the structure inside the positioning box 8.

[0062] In some embodiments, in order to reduce the number of components of the positioning structure, when the RV air conditioner installation positioning device includes a first extension limit block 9 and a second extension limit block 10, the first extension limit block 9 and the second extension limit block 10 are staggered along the extension direction of the positioning member 5. When the first positioning part 5.1 and the second positioning part 5.2 are extended in opposite directions, the first extension limit block 9 and the second extension limit block 10 can block and limit each other, thereby realizing the function of mutual limitation of the two positioning parts, avoiding the need to set a separate limiting component for each positioning part.

[0063] In some embodiments, the first extension stopper 9 is provided at the end of the first support portion 6.1 facing the inner side of the positioning box 8, and / or the second extension stopper 10 is provided at the end of the second support portion 6.2 facing the inner side of the positioning box 8. This design can minimize the length of the first support portion 6.1 or the second support portion 6.2, so that when the two extension stoppers block each other, the first positioning portion 5.1 and the second positioning portion 5.2 are properly extended to the working position.

[0064] The present disclosure also provides a method for installing an RV air conditioner using the above-mentioned RV air conditioner installation and positioning device, comprising:

[0065] Step 1: Adjust the positioning member 5 to the second state. The positioning member 5 is retracted into the positioning box 8 , and the positioning structure reaches a minimum volume, which is smaller than the inner diameter of the mounting hole 3 .

[0066] Step 2: Place the positioning structure into the mounting hole 3.

[0067] Step 3: Adjust the positioning member 5 to the first position. The positioning member 5 extends outside the positioning box 8, and the first positioning portion 5.1 and the second positioning portion 5.2 are supported on opposite side walls of the mounting hole 3. Simultaneously, the first support stopper 11 is slid to the end of the first support portion 6.1 to maintain the first positioning portion 5.1 in the first position. The second support stopper 12 is slid to the end of the second support portion 6.2 to maintain the second positioning portion 5.2 in the second position.

[0068] Step 4: Place the air conditioner 2 so that the connecting part 4 of the air conditioner 2 is matched with the positioning part 5, and the air conditioner 2 is stable without any warping. If the air conditioner 2 is unstable or warped, it means that the gasket 7 is not fully matched with the positioning part 5, and the position of the air conditioner 2 needs to be adjusted. You can use a small shaking motion until the air conditioner 2 is stable without any warping, which means that the air conditioner 2 has been accurately positioned.

[0069] Step 5: Adjust the positioning member 5 to the second state, retract the positioning member 5 into the positioning box 8, and remove the positioning structure from the mounting hole 3.

[0070] Step 6: Complete the installation and positioning of air conditioner 2.

[0071] The RV air conditioner installation method of this embodiment has accurate positioning, requires few auxiliary tools, has high operating efficiency and is easy to dismantle.

[0072] A recreational vehicle air conditioner adopts the above-mentioned recreational vehicle air conditioner installation and positioning device, or adopts the above-mentioned recreational vehicle air conditioner installation method.

[0073] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0074] The above are merely preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure. The above are merely preferred embodiments of the present disclosure.
