A rear housing structure comprising:

the magnetic block comprises a main body and a boss which are integrally formed, wherein the main body is provided with a first surface and a second surface which are arranged oppositely, and the boss is arranged on the first surface and is provided with a side peripheral surface and a top surface; and

the cover body, the magnetic block is embedded in the cover body, the top surface of the boss is exposed in the cover body, the cover body is provided with a first limiting part extending to the first surface, and the first limiting part is used for fixing the magnetic block.

The rear shell structure comprises a magnetic block and a cover body. The magnetic block is embedded in the cover body and clamped by the cover body, and the magnetic block and the cover body can be matched more firmly on the whole structure due to the structural arrangement. Because the magnetic block is embedded in the cover body, namely the magnetic block is fixed with the cover body, a user does not need to additionally install the magnetic block on the cover body, and the installation of the rear shell structure can be directly implemented on the wall body. Therefore, the rear case structure has higher structural reliability and installation convenience.

In particular, the magnetic block may comprise an integrally formed body and boss. The main body is provided with a first surface and a second surface which are arranged oppositely, and the boss is arranged on the first surface of the main body. The main body of the magnetic block embedded in the cover body is tightly attached to the inner side of the structure of the cover body, namely, the inner side of the structure of the cover body is abutted against the magnetic block so as to limit the movement of the magnetic block. On the basis, the cover body can comprise a first limiting part formed by extending the cover body, namely the first limiting part and the cover body are integrally formed, and the first limiting part extends to the first surface of the main body to limit the movement of the main body. In other words, the cover fixes the main body inside the cover by its own structure. Because the main part and the boss integrated into one piece of magnetic block, when the main part is fixed by the structure of lid, the boss is also fixed by the structure of lid in the lump, and the magnetic block is fixed by the structure of lid promptly to let magnetic block and lid more firm in overall structure's cooperation, make the shell structure have better reliability when follow-up installation afterwards.

Therefore, when the user installs the rear shell structure, the user can directly install the cover body embedded with the magnetic block on the wall body. For example, taking the magnetism-attracting wall as an example, the magnetism-attracting wall may be formed by fixing iron accessories, such as an iron hanger and an iron plate, on the surface of a common wall. Therefore, the cover body can be adsorbed on the magnetic wall body through the magnetic block, and the installation of the cover body is realized. When the user needs to change or position adjustment this backshell mechanism, the user only need move the lid alright realize, need not in addition to do other complicated dismantlements and the equipment etc. to this backshell structure again. Therefore, the rear case structure greatly enhances the convenience of installation.

Wherein the top surface of the boss is exposed to the cover, which may allow the cover to be more securely mounted to the wall. For example, during the process of mounting the rear shell structure to the magnetic wall, the user may face the side of the cover body exposed with the boss toward the magnetic wall. Therefore, the magnetic block can be in direct contact with the magnetic wall through the exposed boss to improve the mutual attraction, so that the cover body is better adsorbed on the magnetic wall, and the installation reliability of the rear shell structure is improved.

Therefore, the rear case structure has higher mounting reliability and convenience.

Referring to fig. 1 to 3, in an embodiment, a rear case structure 10 is provided, which includes a magnetic block 100 and a cover 200. The magnetic block 100 is embedded in the cover 200 and is clamped by the cover 200, so that the magnetic block 100 and the cover 200 can be more firmly matched in the whole structure. Since the magnetic block 100 is embedded in the cover 200, that is, the magnetic block 100 is fixed to the cover 200, the user can directly mount the rear housing structure 10 on the wall without additionally mounting the magnetic block 100 on the cover 200. Therefore, the rear case structure 10 has higher structural reliability and mounting convenience.

Specifically, as shown in fig. 4 to 6, the magnetic block 100 may include a body 110 and a boss 120 that are integrally formed. The main body 110 has a first surface 111 and a second surface 112 opposite to each other, and a third surface 113 connected between the first surface 111 and the second surface 112. The boss 120 is disposed on the first surface 111 of the body 110, and the boss 120 has a top surface 121 on a side facing away from the body 110.

As shown in fig. 7 and 8, the cover 200 has a first cover surface 201 and a second cover surface 202 opposite to each other, a cavity 240 capable of accommodating the main body 110 of the magnetic block 100 is formed inside the cover 200, an inner structure of the cover 200 forming the cavity 240 has a first cavity surface 241 and a second cavity surface 242 spaced apart from each other, and a third cavity surface 243 connected between the first cavity surface 241 and the second cavity surface 242.

The second surface 112 and the third surface 113 of the main body 110 of the magnetic block 100 embedded in the cover 200 are closely attached to the inner structure of the cover 200. On the basis, the cover 200 further has a first position-limiting portion 210 extending to the first surface 111 of the main body 110 and closely attached to the first surface 111. Therefore, the cover 200 may fix the body 110 of the magnetic block 100 by its own structure. The first cavity surface 241 is a side of the first position-limiting portion 210 closely attached to the main body 110. The main body 110 of the magnetic block 100 is embedded in the cover 200 through the cavity 240, and the first surface 111, the second surface 112, and the third surface 113 of the main body 110 are respectively closely attached to the first cavity surface 241, the second cavity surface 242, and the third cavity surface 243 of the cover 200, that is, the cover 200 abuts against the first surface 111, the second surface 112, and the third surface 113 of the magnetic block 100 by its own structure to limit the movement of the main body 110, thereby fixing the main body 110 in the structure of the cover 200. Because the main body 110 and the boss 120 of the magnetic block 100 are integrally formed, when the main body 110 is fixed by the structure of the cover 200, the boss 120 is also fixed by the structure of the cover 200, that is, the magnetic block 100 is fixed by the structure of the cover 200, so that the magnetic block 100 and the cover 200 are more firmly matched in the overall structure, and the rear housing structure 10 has better reliability in subsequent installation.

Therefore, when the user installs the rear housing structure 10, the cover 200 embedded with the magnetic block 100 and the wall with magnetism or magnetism affinity can be attracted to each other, and the cover 200 can be installed on the wall. For example, the magnetism-attracting wall body may refer to fixing iron accessories, such as an iron hanger, an iron plate, etc., on the surface of a common wall body. Thus, the cover 200 can be attached to the magnetic wall through the magnetic block 100, thereby realizing the installation of the cover 200. When a user needs to replace or adjust the position of the rear housing structure 10, the user only needs to move the cover 200, and does not need to perform complicated disassembly and assembly of the cover 200. Therefore, the rear housing structure 10 greatly promotes the convenience of installation.

The cover body 200 is further provided with an exposure opening 230, the boss 120 extends into the exposure opening 230 and is exposed to the cover body 200 through the exposure opening 230, that is, the top surface 121 of the boss 120 is exposed to the outside and is not shielded by the structure of the cover body 200, which can make the cover body 200 be more firmly mounted on the wall. For example, during installation of the rear housing structure 10 to a magnetic-philic wall, a user may orient the side of the cover 200 exposed by the bosses 120 toward the magnetic-philic wall. Therefore, the magnetic block 100 can directly contact with the magnetic wall through the exposed top surface 121 to promote the mutual attraction, so that the cover 200 can be better attracted to the magnetic wall, thereby promoting the installation reliability of the rear housing structure 10.

Referring to fig. 1, 2, 7 and 8, the first stopper portion 210 may be annularly provided to the boss 120.

For example, in the embodiment shown in fig. 3 and 8, the first position-limiting portion 210 of the cover 200 extends along the circumferential direction of the first surface 111 of the main body 110 to form a ring shape, i.e., the first position-limiting portion 210 is disposed around the boss 120. With such a structure, the first position-limiting portion 210 can be tightly attached to the main body 110 along 360 degrees of the circumferential direction of the first surface 111 of the main body 110, so that the main body 110 can be fixed by the first position-limiting portion 210 along 360 degrees of the circumferential direction of the first surface 111, that is, the magnetic block 100 can be more firmly fixed in the cover 200, and the installation reliability of the rear housing structure 10 is further improved.

Further, referring to fig. 8, the first position-limiting portion 210 may abut against the boss 120.

For example, in the embodiment shown in fig. 8, the first position-limiting portion 210 disposed around the boss 120 extends toward the side peripheral surface 122 of the boss 120, and the first position-limiting portion 210 is closely attached to the entire side peripheral surface 122 of the boss 120, that is, the first position-limiting portion 210 abuts against the entire side peripheral surface 122 of the boss 120. Such a structural arrangement can prevent the boss 120 from shaking in the parallel direction of the first surface 111 of the main body 110, reduce stress at the joint of the boss 120 and the main body 110, make the joint of the boss 120 and the main body 110 more reliable, prolong the service life of the magnetic block 100, and improve the mounting reliability of the rear housing structure 10.

Referring to fig. 4 and 8, in one embodiment, the body 110 and the boss 120 of the magnetic block 100 each have a cylindrical shape. The boss 120 is located at the center of the first surface 111 of the main body 110, that is, the first position-limiting portion 210 disposed around the boss 120 uniformly extends to the entire first surface 111 of the main body 110. When the magnetic block 100 tends to leave the cover 200 from the side of the first surface 111, the structure can make the stress on the first surface 111 of the main body 110 abutted by the first limiting portion 210 more uniform, thereby improving the connection reliability between the magnetic block 100 and the cover 200.

Referring to fig. 4 and 8, in one embodiment, the top surface 121 of the boss 120 is flush with the first cover surface 201 of the cover 200. Due to the adoption of the structure, when the rear shell structure 10 is mounted on the iron hanger on the surface of the wall, the top surface 121 of the boss 120 can be directly contacted with the iron hanger on the surface of the wall, so that the rear shell structure 10 has a better adsorption effect after being mounted, and the mounting reliability of the rear shell structure 10 is further improved.

Referring to fig. 5 to 8, in an embodiment, the magnetic block 100 is provided with a positioning hole 130 at the side of the second surface 112. Specifically, as shown in fig. 7 and 8, before the rear housing structure 10 is manufactured by using the injection molding process, the positioning posts in the mold (not shown in the drawings) may be inserted into the positioning holes 130 of the magnetic block 100 to fix the magnetic block 100. Then, according to the injection molding process, plastic is injected into the mold to form the cover 200, thereby completing the manufacture of the rear housing structure 10. The cover 200 has a positioning hole 250 formed on the second cover surface 202, and the positioning hole 250 is communicated with the positioning hole 130 of the magnetic block 100. The rear case structure 10 manufactured by the injection molding process is more compact in overall structure, and the connection reliability of the magnetic block 100 and the cover body 200 is improved.

Further, referring to fig. 7 and 8, the cover body 200 is protruded with a second position-limiting portion 220 into the positioning hole 130 around the opening edge of the positioning hole 130, and the second position-limiting portion 220 is used for abutting against the magnetic block 100 to further improve the connection reliability between the magnetic block 100 and the cover body 200.

Specifically, a chamfering process may be performed at an opening edge of the magnetic block 100 around the positioning hole 130. When the rear case structure 10 is manufactured using an injection molding process, the plastic injected into the mold forms the second stopper 220 of the cover 200 at the opening edge of the positioning hole 130 of the magnetic block 100. The second position-limiting portion 220 is matched with the chamfer at the opening edge of the positioning hole 130 of the magnetic block 100 in shape, i.e. the second position-limiting portion 220 is tightly attached to the magnetic block 100. The second cavity surface 242 is a side of the second position-limiting portion 220 closely attached to the main body 110. Therefore, the structural arrangement of the second limiting portion 220 can make the cover body 200 have a better fixing effect on the magnetic block 100, i.e. the connection reliability between the magnetic block 100 and the cover body 200 is improved.

Referring to fig. 1 and 2, the magnetic blocks 100 may include at least two, and a plurality of magnetic blocks are symmetrically distributed along the center of a surface of the cover 200 where the boss 120 is exposed.

For example, in the embodiment shown in fig. 1 and 2, the number of the magnetic blocks 100 is 2, including the first magnetic block 101 and the second magnetic block 102. The first magnetic block 101 and the second magnetic block 102 are symmetrically distributed along the center of the surface of the cover 200 where the boss 120 is exposed. When a user mounts the rear housing structure 10 on the magnetic wall, the interaction force generated between the magnetic block 100 and the magnetic wall is more uniformly distributed on the cover 200, so as to attach the cover 200 to the wall more firmly, and the mounting reliability of the rear housing structure 10 is higher.

Referring to fig. 2, in an embodiment, there is also provided a building intercom including a back panel 11 and a rear housing structure 10 as described in any one of the embodiments of fig. 1, 2, 3, 7 and 8. Wherein the rear housing structure 10 is connected to the back panel 11, thereby improving the installation convenience and reliability of the building intercom.

For example, the side of the rear housing structure 10 facing away from the top surface 121 of the boss 120 is fixedly connected to the back plate 11, and the back plate 11 is integrally formed with the rear housing structure 10. Therefore, when a user installs the building intercom device on a magnetic wall, the building intercom device can be adsorbed on the magnetic wall through the rear shell structure 10 integrally formed with the back plate 11, and the building intercom device is convenient to install and high in reliability. In addition, the user only needs to directly move the building intercom device, so that the position adjustment and the replacement can be realized, and the installation convenience is greatly improved.

For another example, the side of the rear housing structure 10 facing away from the top surface 121 of the boss 120 is detachably connected to the building intercom device, that is, the user can determine whether to connect the rear housing structure 10 to the building intercom device for use according to actual needs, so that the flexibility of use of the building intercom device and the use experience of the user are improved.
