In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment discloses an air-conditioning indoor unit hinge mechanism, which comprises a first component and a second component which are connected in a hinge mode, wherein rotating shafts (30 and 40) for hinge are respectively formed on two back sides and two opposite sides of the first component, and correspondingly, two shaft holes (11 and 12) which are coaxial and are inserted and assembled with the rotating shafts (30 and 40) are formed in the second component.

In order to solve the problems of difficult disassembly and assembly and easy breakage of the hinge mechanism on the existing air-conditioning indoor unit, one rotating shaft 30 of the two rotating shafts (30 and 40) can be axially and telescopically arranged on the first part between a hinge position and a non-hinge position. Of course, in other embodiments, both shafts 30 may be designed to be axially telescopically mounted to the first member between an articulated position and a non-articulated position. In order to simplify the structure, the other shaft 40 is integrally formed with the first member in this embodiment.

When the first part and the second part need to be assembled, firstly, the rotating shaft 30 on the first part is retracted to a non-hinged position, then, after the rotating shaft 40 which is integrally formed with the first part is inserted and matched with one shaft hole 12, the rotating shaft 30 naturally aligns to the other shaft hole 11, and then the rotating shaft 30 can be extended to the hinged position, so that the assembling between the first part and the second part can be completed by inserting and matching the rotating shaft 30 and the shaft holes 11; when the first component needs to be detached from the second component, the first component and the second component can be detached and separated only by retracting the rotating shaft 30 to the non-hinged position and withdrawing the other rotating shaft 40 integrally formed with the first component from the shaft hole 12. The whole assembling or disassembling process is simple to operate, labor-saving and time-saving, and more importantly, the problem of deformation of the parts of the second part, which are provided with the shaft holes (11 and 12), and the rotating shafts (30 and 40) is solved, so that potential safety hazards such as breakage and breakage easily occurring in the prior art are effectively avoided.

In order to solve the problem of difficulty in assembling and disassembling the support rods on the framework of the existing air-conditioning indoor unit, referring to fig. 1 to 3, the second component of the hinge mechanism of the air-conditioning indoor unit in this embodiment is the framework 10 of the air-conditioning indoor unit, two shaft holes (11, 12) are respectively located on two ear plates arranged in parallel in the framework 10, the first component is an L-shaped support rod 20, and rotating shafts (30, 40) are arranged at one end of the support rod 20.

As shown in fig. 2, a receiving groove 21 capable of receiving the rotating shaft 30 is formed in the support rod 20, the rotating shaft 30 is axially retractable to be extendable and retractable relative to the receiving groove 21, and when the rotating shaft 30 is extended to the hinge position, a part of the rotating shaft 30 is located outside the receiving groove 21 for being inserted into and engaged with the shaft hole 11; when the rotating shaft 30 is retracted to the non-hinged position, the rotating shaft 30 may be partially or completely located in the accommodating groove 21.

In order to improve the reliability of the hinge, the present embodiment further forms a locking structure on the support rod 20, and when the rotating shaft 30 is extended to the hinge position, the rotating shaft 30 can be maintained at the position by the locking structure.

In order to form a stop fit with the locking structure and prevent the rotating shaft 30 from moving along the axial direction thereof at the hinge position, the rotating shaft 30 includes a connecting block 31 for fitting the locking structure and a shaft body 32 located at one end of the connecting block 31 and adapted to be inserted into and fitted with the shaft hole 11, and the connecting block 31 and the shaft body 32 can be integrally formed by injection molding, as shown in fig. 3.

For convenience of illustration, a side wall of the accommodating groove 21 opposite to the extending and contracting direction of the rotating shaft 30 is set as the first side wall 211, and a side wall of the accommodating groove 21 intersecting with the first side wall 211 is set as the second side wall 212. In the process of extending the rotation shaft 30 to the hinge position, the shaft body 32 may be directly extended through the top end of the first sidewall 211 of the receiving groove 21, or an escape recess may be formed in the first sidewall 211 of the receiving groove 21. In order to improve the coaxiality of the shaft body 32 and the other rotating shaft 40 in the hinge position so as to ensure the reliability of the rotating connection, the present embodiment is provided with an insertion hole 213 which is in positioning and inserting fit with the shaft body 32 at the first side wall 211 of the accommodating groove 21. In order to facilitate the axial extension and contraction of the rotating shaft 30 between the hinge position and the non-hinge position, the connecting block 31 is further provided with a handheld portion, the structure of the handheld portion is not unique, specifically, the connecting block 31 extends outwards to form a plurality of pushing blocks 33 as the handheld portion, and the pushing blocks 33 can be conveniently pushed by a user in a handheld manner and can also be used for being matched with the stopping blocks of the locking structure.

As to the structural form of the locking structure, in some embodiments the locking structure may be a separate component: when the rotating shaft 30 extends to the hinge position, a certain area is reserved in the accommodating groove 21, the block can be inserted into and blocked off the area, and the block pushes the connecting block 31 to abut against the first side wall 211 of the accommodating groove 21 so as to axially fix the rotating shaft 30 at the hinge position.

In order to reduce the number of components, in the present embodiment, the relief opening 22 is formed at the bottom of the receiving groove 21, and the locking structure includes a buckle extending from the bottom of the receiving groove 21 into the relief opening 22, so that when the connecting block 31 abuts against the first sidewall 211 of the receiving groove 21, the axial movement of the rotating shaft 30 can be limited by the buckle and the connecting block 31. Specifically, the catch includes a cantilever 23 extending in the telescopic direction of the rotation shaft 30 and a catch protrusion 24 formed at the free end of the cantilever 23. When the rotating shaft 30 extends to the hinge position, one end of the connecting block 31 adjacent to the shaft body 32 abuts against the first side wall 211 of the accommodating groove 21, and one end of the connecting block 31 far away from the shaft body 32 is in clamping fit with the clamping protrusion 24, so that the axial fixation of the rotating shaft 30 is ensured.

When the connecting block 31 and the receiving groove 21 form curved surfaces and are fitted to each other, in order to avoid rotation of the rotating shaft 30 in the receiving groove 21, the locking structure of the present embodiment further includes a stop block 25 extending from the supporting rod 20, and the stop block 25 and the connecting block 31 form stop fit or insertion fit to fix the rotating shaft 30 in the circumferential direction, specifically, two stop blocks 25 are respectively extended on two sides of the rotating shaft 30 in the extending and retracting direction to limit clockwise and counterclockwise rotation of the rotating shaft 30. In other embodiments, the receiving groove 21 with a non-circular or arc-shaped cross section may be further formed, so that the second sidewall 212 of the receiving groove 21 is used to achieve the purpose of stopping the rotation of the rotating shaft 30.

In order to facilitate the detachment and installation between the support rod 20 and the rotating shaft 30, in the embodiment, a detachment and installation area D for conveniently taking and placing the rotating shaft 30 is further formed in the accommodating groove 21, and when the rotating shaft 30 needs to be detached, the rotating shaft 30 can be retracted into the detachment and installation area D, so that the rotating shaft 30 can be easily taken out; when the rotating shaft 30 needs to be installed, the rotating shaft 30 can be placed into the dismounting area D and then pushed to the hinged position or the non-hinged position. In order to reduce the slot length of the receiving slot 21, the rotating shaft 30 in the non-hinged position in the present embodiment is also correspondingly located in the dismounting area D, as shown in fig. 2 and 5.

For example, in some other embodiments, when the free end of the cantilever 23 is an end of the cantilever 23 adjacent to the insertion hole 213, a part of the cantilever 23 may be located in the detachment region D, and when the rotating shaft 30 extends to the hinge position and is engaged with the engaging protrusion 24, a part of the cantilever 23 is exposed, and the engaging protrusion 24 may be pushed by the cantilever 23 to release the engaging engagement with the connecting block 31.

In order to facilitate the automatic clamping between the buckle and the connecting block 31, as shown in fig. 2 and 4, the free end of the cantilever 23 in this embodiment is the end of the cantilever 23 away from the insertion hole 213, and the clamping protrusion 24 on the free end of the cantilever 23 is located in the dismounting region D, when the rotating shaft 30 is placed in the dismounting region D, as shown in fig. 5, the rotating shaft 30 presses the clamping protrusion 24, the clamping protrusion 24 penetrates through the relief opening 22 to be pushed out of the accommodating groove 21 while the cantilever 23 is elastically deformed, in the process of pushing the rotating shaft 30 toward the hinge position, the rotating shaft 30 gradually moves out of the dismounting region D, after the connecting block 31 completely moves out of the dismounting region D and abuts against the first side wall 211, the rotating shaft 30 extends to the hinge position, and at this time, the cantilever 23 drives the clamping protrusion 24 to reset and simultaneously realizes the clamping fit between the clamping protrusion 24 and the connecting block 31.
