The electric appliance adopting the internal hinge structure as shown in the attached figures 1-4 comprises a box body 1 for storing articles and a door body 2 for opening and closing the box body 1, wherein an installation cavity is formed on the connecting side of the box body 1 and the door body 2, and the box body 1 is hinged with the door body 2 through the internal hinge structure positioned in the installation cavity; the inner hinge structure comprises a first inner hinge part 3, a second inner hinge part 4 and a hinge rotating shaft 5; the first inner hinge member 3 includes a first connection portion 301, and is mounted on the door body 2 through the first connection portion 301; the second inner hinge member 4 includes a second connection portion 401, and is mounted on the case 1 through the second connection portion 401; the first inner hinge part 3 is hinged with the second inner hinge part 4 through the hinge rotating shaft 5. In this embodiment, after adopting interior hinge structural formula design, interior hinge structure is located the installation intracavity, can not see the hinge structures of these door body 2 and box 1 in the outward appearance of electrical apparatus, has improved the compactness and the aesthetic property of electrical apparatus product on the one hand, on the other hand also has better waterproof and dustproof effect, reduces dirty accumulation, is favorable to keeping the safety and sanitation of electrical apparatus product.

Specifically, referring to fig. 1 and 2, in one embodiment, the outside of the installation cavity includes an extension 201 extending from the door 2 toward the box 1, and an outside gap of the installation cavity is formed between the extension 201 and the box 1 or the door 2. That is, the installation cavity is mainly formed by enclosing the door body 2, the box body 1 and the inner hinge structure, the extension part 201 is arranged at the outer side of the installation cavity, and the inner hinge structure is arranged at the inner side of the installation cavity. Because the door body 2 and the box body 1 are required to be rotationally connected, that is, the door body and the box body 1 need to be relatively rotated, a gap is required to be reserved between the door body and the box body, and by adopting the installation cavity of the embodiment, the outside gap between the extension part 201 and the box body 1 can be smaller to improve the relative tightness of the installation cavity, and the preferable range is that the width of the outside gap is smaller than 2mm, for example, the width of the outside gap in the embodiment is 1mm, so that the effects of beautifying the appearance of an electrical product and better dust and water proofing can be effectively realized.

In this embodiment, the extending portion 201 is disposed on the door 2, and during the rotation of the door 2 relative to the box 1, the extending portion 201 rotates toward the box 1, and since the gap between the extending portion 201 and the box 1 is small, in this embodiment, the box 1 is provided with the avoiding groove 101 that avoids the extending portion 201, and during the relative rotation of the two, the extending portion 201 is not blocked, so that the door 2 can normally rotate relative to the box 1, and always maintains a small gap with the box 1, so as to ensure the main functional effect of the present utility model. It is easy to understand that the extension 201 may be disposed on the case 1, that is, the extension 201 extends from the case 1 toward the door 2, and similarly, a smaller gap may be effectively ensured during the relative rotation between the door 2 and the case 1.

Referring to the drawings, the first inner hinge member 3 further includes a limiting portion 302 capable of cooperating with the second inner hinge member 4 to limit the maximum rotation angle of the two, where the limiting portion 302 and the first connecting portion 301 form an included angle. In the closed state of the door body 2, the limiting part 302 is located at a position far away from the second inner hinge member 4, when the door body 2 rotates to be opened, the first inner hinge member 3 rotates relative to the second inner hinge member 4 along with the rotation of the door body 2, so that the limiting part 302 moves towards the direction of the second inner hinge member 4, and when the limiting part 302 is abutted with the second inner hinge member 4 and is blocked and cannot move continuously, the maximum angle of the relative rotation of the first inner hinge member 3 and the second inner hinge member 4 is obtained, at the moment, the door body 2 of the electric appliance is opened to the maximum state, namely, the maximum opening angle of the door body 2 is limited by the cooperation of the limiting part 302 and the second inner hinge member 4, and the reasonable opening angle range of the door body 2 can be ensured without additional components. Specifically, the range of the included angle formed by the limiting portion 302 and the first connecting portion 301 is 90 ° -180 °, that is, in practical application, the maximum opening angle of the door body 2 may be specifically limited according to needs, for example, as shown in fig. 4, the included angle in this embodiment is 110 °, and the maximum opening angle of the door body 2 may be limited to 110 °.

As described above, in this embodiment, the angle limitation is achieved by the cooperation between the limiting portion 302 of the first inner hinge member 3 and the second inner hinge member 4, specifically, the second inner hinge member 4 includes the abutting portion 402 that can form the maximum rotation angle limitation by abutting and cooperating with the limiting portion 302, and the abutting portion 402 is connected with the second connecting portion 401 and forms a clearance structure for avoiding the rotation process of the limiting portion 302. For example, in this embodiment, the abutting portion 402 and the second connecting portion 401 are connected to form a member with a Z-shaped cross section, and the initial position lower limit portion 302 is at one end far away from the second connecting portion 401, so that the two limit portions 302 can be avoided to relatively rotate; when the two are in mutual abutting connection, the two are limited in relative rotation, so that the aim of limiting the maximum opening angle of the door body 2 is fulfilled. Of course, the second inner hinge member 4 is not limited to the shape of the Z-section in the present utility model, and may be any other shape such as N-shape or arc shape, as long as interference with the rotation of the first inner hinge member 3 can be avoided. In addition, in the present embodiment, the first inner hinge member 3 is mounted on the door body 2, the second inner hinge member 4 is mounted on the case 1, and in some embodiments, the first inner hinge member 3 may be mounted on the case 1, and the second inner hinge member 4 may be mounted on the door body 2, which may also implement the main functional structure of the present utility model.

As shown in the drawings, the inner hinge structure of the utility model is applied to small electric products needing to open and close the door body 2, for example, in the embodiment, the electric appliance is a vehicle-mounted refrigerator, the door body 2 is the door body 2 of the vehicle-mounted refrigerator, the box body 1 is the box body 1 of the vehicle-mounted refrigerator, and the vehicle-mounted refrigerator has the characteristics of simple appearance, small gap, better waterproof and dustproof effects and the like after the structural design of the utility model is adopted.

The foregoing is illustrative of the preferred embodiments of the present utility model, and is not to be construed as limiting the claims. The utility model is not limited to the above embodiments, the specific construction of which is susceptible to variations, in any case all of which are within the scope of the utility model as defined in the independent claims.
