When the hinge assembly 30 is in the process of opening, the second hinge member 32 and the sliding piece 40 move relative to the first hinge member 31 , and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40 .

Here, "at least one

shaft body

311, 312 located on the first hinge part 31" means that at least one

shaft body

311, 312 is arranged on the first hinge part 31, and the

shaft body

311, 312 and the first hinge part 31 can be It is integrally formed, or can be assembled together. For the explanation of "located" in other parts of the present invention, refer to the description here, and will not be repeated hereafter.

It should be noted that "the hinge assembly 30 is in the opening process" means that the second hinge member 32 is opened in a direction away from the first hinge member 31, that is, the second hinge member 32 acts in one direction to drive the second hinge member 32 to move away from the first hinge member 31. The direction movement of the first hinge member 31 , when the hinge assembly 30 is installed on the refrigerator 100 , the opening process of the hinge assembly 30 corresponds to the opening process of the door body 20 .

In this embodiment, first the second hinge member 32 moves relative to the first hinge member 31 together with the sliding piece 40, and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40. It can be seen that in the hinge assembly 30 During the whole opening process, two kinds of movements are realized. The two movements can realize the change of the position of the rotating shaft, which can effectively control the movement track of the door body, thereby improving the degree of freedom in the opening and closing process of the door body 20 of the refrigerator 100, especially the embedded In the field of refrigerators, the door body 20 can be prevented from interfering with surrounding cabinets or walls during the opening and closing process by switching the rotation axis.

In the first embodiment, referring to FIG. 2 to FIG. 5 , the hinge assembly 30 further includes a first shaft 311 and a second shaft 312 on the first hinge 31 , and a first groove 401 on the slide 40 And the second groove body 402 and the third groove body 321 and the fourth groove body 322 located on the second hinge 32, the first groove body 401 cooperates with the first shaft body 311, the second groove body 402 and the second shaft body The bodies 312 cooperate with each other.

When the hinge assembly 30 is in the closed state, the first shaft body 311 extends into the overlapping first groove body 401 and the third groove body 321, and the second shaft body 312 extends into the overlapping second groove body 402 and the fourth groove body. In the groove body 322 , the sliding piece 40 is relatively stationary relative to the second hinge member 32 .

Here, "overlapping each other" means that the shapes of the first groove body 401 and the third groove body 321 are consistent, and at the same time, the shapes of the second groove body 402 and the fourth groove body 322 are consistent.

When the hinge assembly 30 is in the opening process, the second hinge member 32 and the sliding piece 40 move relative to the first hinge member 31 until the first shaft body 311 is limited to the first groove body 401 and/or the second shaft body 312 is limited to the The second slot body 402 , and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40 .

In this embodiment, the locking and unlocking between the first hinge member 31, the second hinge member 32 and the sliding piece 40 can be controlled through the structure of the hinge assembly 30, specifically, the second hinge member 32 and the sliding piece are controlled first. 40 lock each other, and then control the second hinge 32 and slide 40 to move relative to the first hinge 31 together, and then control the unlocking between the second hinge 32 and slide 40 and the first hinge 31 and slide 40 are mutually locked, thereby controlling the movement of the second hinge member 32 relative to the sliding piece 40 .

Specifically, in this embodiment, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α1, the second hinge member 32 and the sliding piece 40 are relative to the first rotation axis P1 as the central axis. The hinge member 31 rotates, and when the hinge assembly 30 continues to open from the first opening angle α1 to the second opening angle α2, the second hinge member 32 rotates relative to the sliding plate 40 around the second rotation axis P2.

Here, the first rotation axis P1 may be a virtual axis or a physical axis.

A virtual shaft refers to a shaft that does not actually exist in the hinge assembly 30 , and a real shaft refers to components actually included in the hinge assembly 30 .

In addition, the first rotation axis P1 may be a non-fixed axis or a fixed axis.

The non-fixed axis means that the position of the first rotation axis P1 is always changing, that is, the relative position between the first rotation axis P1 and the box body 10 or the door body 20 is changing, while the fixed axis refers to the first rotation axis The position of P1 is fixed, that is, the relative position between the first rotation axis P1 and the box body 10 or the door body 20 is fixed.

Similarly, the second rotation axis P2 can be a virtual axis or a physical axis, and the second rotation axis P2 can be a non-fixed axis or a fixed axis, and the second rotation axis P2 and the first rotation axis P1 are mutually staggered, that is, the second rotation axis The position of P2 does not coincide with the position of the first rotation axis P1.

It can be seen that the hinge assembly 30 of this embodiment can effectively control the sequence of the two rotations. During the two rotations, there is a change in the position of the rotation axis, which can effectively control the movement track of the door body 20, thereby improving the door body 20 of the refrigerator 100. The degree of freedom in the opening and closing process, especially in the field of built-in refrigerators, can prevent the door body 20 from interfering with surrounding cabinets or walls during the opening and closing process by switching the rotation axis.

In order to further illustrate the movement track of the hinge assembly 30 , a simple schematic diagram of the hinge assembly 30 assembled to the refrigerator 100 and the refrigerator 100 embedded in the cabinet 200 is taken as an example for illustration with reference to FIG. 5 .

The box body 10 includes an opening 102 and a front end surface 103 arranged around the opening 102. The box body 10 also includes an accommodating chamber D and an outer side surface 13 adjacent to the hinge assembly 30 and on the extension of the rotation path of the door body 20. The door body 20 includes a The front wall 21 of the accommodating chamber D and the side wall 22 always sandwiched between the front wall 21 and the accommodating chamber D, a side edge 23 is formed between the front wall 21 and the side wall 22 .

The hinge assembly 30 is configured such that: when the first rotation axis P1 is actuated, there is a first distance between the first rotation axis P1 and the front end surface 103 of the box body 10; when the second rotation axis P2 is actuated, the second rotation There is a second distance between the axis P2 and the front end surface 103 of the box body 10 , and the second distance is greater than the first distance.

In addition, when the first rotation axis P1 is activated, there is a third distance between the first rotation axis P1 and the outer surface 13 of the box body 10; when the second rotation axis P2 is activated, the second rotation axis P2 and the box body There is a fourth distance between the outer sides 13 of 10, and the fourth distance is smaller than the third distance.

Here, "the first rotation axis P1 is actuated" means that the first rotation axis P1 is in the working state, that is, at this time, the second hinge member 32 and the sliding plate 40 rotate relative to the first hinge member 31. Similarly, "the second rotation "Axis P2 is active" means that the second rotation axis P2 is in a working state, that is, the second hinge member 32 rotates relative to the sliding piece 40 at this moment.

It should be noted that the above-mentioned distance refers to the distance between the first rotation axis P1 and the second rotation axis P2 at the position and the front end surface 103 and the outer surface 13 of the box body 10 when the hinge assembly 30 moves to a certain position. , not the distance in the closed state.

The specific instructions are as follows:

In actual operation, in order to improve the embedding effect, it is preferable to completely embed the refrigerator 100 into the cabinet 200. The refrigerator 100 is a free embedded refrigerator, that is, the front end 201 of the cabinet 200 and the front wall 21 of the door 20 are away from the side of the cabinet 10. Located on the same plane, or the front wall 21 of the door body 20 does not protrude from the front end 201 of the cabinet 200 at all.

In the prior art, all refrigerators are single-axis refrigerators, and a certain distance needs to be kept between the rotation axis of the refrigerator and the side wall and front wall of the refrigerator, so that there is enough space for foaming or other processes, that is, the existing The position of the rotation axis of the refrigerator is roughly located at the position of the uniaxial shaft body P3 in FIG. 203 is set corresponding to the side edge 23 of the door body 20. When the door body 20 is opened, the side edge 23 will interfere with the door body 20 to limit the maximum opening angle of the door body 20. In order to ensure the normal opening of the door body 20, the prior art A common practice is to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, which needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

In conjunction with FIG. 5 , the shaded area represents the door body 20 in the closed state. When the door body 20 is in the process of opening, if the door body 20 always rotates around the uniaxial shaft body P3 (that is, the prior art), refer to FIG. 5 The dotted line door body 20' in the figure, because the uniaxial shaft body P3 is close to the front end surface 103, that is, the uniaxial shaft body P3 is far away from the front end 201 of the cabinet 200 at this time, when the door body 20' is opened to a certain angle, the corners 203 of the cabinet 200 It will interfere with the door body 20' to limit the maximum opening angle of the door body 20'.

However, in this embodiment, the door body 20 first rotates with the first rotation axis P1 as the central axis. Specifically, the second hinge member 32 and the sliding piece 40 rotate at a certain angle relative to the first hinge member 31 together. 32. As the position of the sliding piece 40 changes, the relative position of the second rotation axis P2 to the box body 10 also changes, and the second rotation axis P2 gradually moves away from the front end surface 103, that is, the second rotation axis P2 gradually approaches the front end of the cabinet 200 201, at this time, the door body 20 rotates with the second rotation axis P2 at the current position as the central axis, because the second rotation axis P2 at this time is farther away from the front end surface 103 of the box body 10 than the first rotation axis P1 , referring to the solid line door body 20 in Figure 5, the interference effect of the corners 203 of the cabinet 200 on the door body 20 is greatly reduced, and the corners 203 of the cabinet 200 will interfere with each other when the door body 20 is opened to a relatively large angle, thereby greatly improving the door body. The maximum opening angle of the body 20.

That is to say, in this embodiment, the door body 20 is opened to a certain angle and then switched to rotate around the second rotation axis P2, which can effectively increase the maximum opening angle of the door body 20 under the premise of ensuring that the refrigerator 100 is freely embedded in the cabinet 200 , thereby facilitating the user to operate the refrigerator 100, which can greatly improve user experience.

Moreover, in this embodiment, there is no need to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, and the seamless connection between the refrigerator 100 and the cabinet 200 can be achieved, which greatly improves the embedding effect.

In addition, while the second rotation axis P2 of this embodiment gradually moves toward the front end 201 of the cabinet 200, it also gradually moves closer to the inner wall 202 of the cabinet 200. When the central axis rotates, the second rotation axis P2 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first rotation axis P1 at this time. In this way, the maximum opening angle of the door body 20 can be increased, and the door can be opened more easily. The body 20 is away from the box body 10 to increase the opening of the box body 10, which facilitates the opening and closing of shelves, drawers, etc. in the box body 10, or in other words, can facilitate the picking and placing of articles.

Certainly, the second rotation axis P2 finally serving as the central axis can also be located at other positions. The rotation axis P1 is close to the front end 201 of the cabinet 200 , and the second rotation axis P2 is farther away from the inner wall 202 of the cabinet 200 than the first rotation axis P1 and so on.

It can be understood that the slide 40 controls the switching sequence of the first hinge 31 and the second hinge 32 during the opening and closing of the door 20 , which can effectively prevent the door 20 from interfering with the cabinet 200 during opening and closing.

In this embodiment, referring to FIG. 2 to FIG. 5 , the hinge assembly 30 further includes a first relief groove 323 connected to the third groove body 321 and a second relief groove 324 connected to the fourth groove body 322 , when the second hinge When the component 32 moves relative to the sliding piece 40 , the first shaft body 311 moves in the first relief groove 323 , and the second shaft body 312 moves in the second relief groove 324 .

Both the first relief groove 323 and the second relief groove 324 are arc grooves, and the center axis of the arc groove is the second rotation axis P2.

Here, the second hinge member 32 and the sliding piece 40 are actually matched by two parts, one part is the connection of the rotating assembly 50, and the other part is the first groove body 401 and the third groove body 321 that cooperate with each other and the mutual cooperation. The matched second tank body 402 and the fourth tank body 322, wherein, since the central axis when the third tank body 321 and the fourth tank body 322 rotate is the first rotation axis P1, and the central axis when the rotating assembly 50 rotates is The second rotation axis P2, the second hinge member 32 cannot rotate with the first rotation axis P1 and the second rotation axis P2 whose positions are inconsistent at the same time, that is, when the first shaft body 311 rotates in the third groove body 321 (or the second rotation axis P2 When the shaft body 312 rotates in the fourth groove body 322), the rotating assembly 50 cannot drive the second hinge member 32 to rotate relative to the sliding piece 40, that is to say, the second hinge member 32 is opposite to the sliding piece 40 at this time. stationary.

Specifically, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the first shaft 311 is located in the third groove 321 (or the second shaft 312 is located in the fourth groove 322), Due to the restrictive effect of the first shaft body 311 on the third groove body 321, the second hinge member 32 cannot rotate relative to the sliding piece 40 with the second rotation axis P2 as the central axis, that is, the second hinge member 32 and the sliding piece 40 are relatively stationary , at this time, through the movement of the first shaft body 311 in the first groove body 401 and the third groove body 321 (or the movement of the second shaft body 312 in the second groove body 402 and the fourth groove body 322), The second hinge member 32 and the sliding piece 40 can rotate relative to the first hinge member 31 together until the first shaft body 311 is limited to the first groove body 401 and/or the second shaft body 312 is limited to the second groove body 402, at this time , the sliding piece 40 cannot continue to rotate relative to the first hinge member 31 , and the first hinge member 31 and the sliding piece 40 are mutually locked.

Then, when the hinge assembly 30 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, since the hinge assembly 30 also has the first relief groove 323 which communicates with the third groove body 321 and communicates with the fourth groove The second relief groove 324 of the body 322 moves in the first relief groove 323 through the first shaft body 311 with the second rotation axis P2 as the center axis, and the second shaft body 312 takes the second rotation axis P2 as the center axis The movement in the second relief slot 324 can drive the second hinge member 32 to rotate relative to the sliding piece 40 .

It can be understood that, in other embodiments, other structures may also be added to realize that the second hinge member 32 and the sliding piece 40 remain relatively stationary during the process of opening from the closed state to the first opening angle α1.

In this embodiment, the second rotation axis P2 is a fixed axis, and the second hinge member 32 rotates relative to the sliding piece 40 around the second rotation axis P2 as a central axis.

The second rotation axis P2 can be a virtual axis or a physical axis, which can be determined according to actual conditions.

In this embodiment, in combination with FIGS. 2 to 5 , the rotating assembly 50 includes a third shaft 403 and a round hole 325 located between the sliding plate 40 and the second hinge 32, and the third shaft 403 serves as the second rotating The shaft P2 rotates in the circular hole 325 .

Here, the second rotation axis P2 is a solid axis, the third shaft body 403 is located on the side of the slide 40 close to the second hinge 32 , and the round hole 325 is located on the second hinge 32 , when the second hinge 32 is opposite to the slide 40 When rotating, the third shaft body 403 rotates in place in the circular hole 325 , the first shaft body 311 slides in the first relief groove 323 , and the second shaft body 312 slides in the second relief groove 324 .

In addition, the rotating assembly 50 further includes a protruding portion 326 and a sliding slot 404 located between the sliding piece 40 and the second hinge member 32 , and the protruding portion 326 slides in the sliding slot 404 with the second rotating axis P2 as a central axis.

At this time, when the second hinge member 32 rotates relative to the sliding piece 40, the third shaft body 403 rotates in place in the circular hole 325, and the protruding part 326 slides in the slide groove 404 with the second rotation axis P2 as the central axis, thus , which can improve the stability of the rotation of the second hinge member 32 relative to the sliding piece 40 .

In addition, when the protruding part 326 slides to the end of the chute 404 in the chute 404 (that is, when the protruding part 326 slides to the limit position), the first hinge part 32 cannot continue to rotate relative to the sliding piece 40, and can pass through the chute. The length of 404 controls the maximum opening angle of the door body 20, but not limited thereto.

In other embodiments, the rotating assembly 50 may not include the third shaft body 403 and the round hole 325 , that is, the second rotating axis P2 is a virtual axis.

That is to say, the rotating assembly 50 may only include the third shaft body 403 and the round hole 325 instead of the protruding portion 326 and the slide groove 404, and the second rotating axis P2 at this time is a physical axis, or the rotating assembly 50 may only Including the protrusion 326 and the sliding groove 404, but not including the third shaft body 403 and the round hole 325, the second rotation axis P2 at this time is a virtual axis, or the rotating assembly 50 includes the protrusion 326, the sliding groove 404, the second The triaxial body 403 and the circular hole 325, at this time, the second rotation axis P2 is a physical axis.

In this embodiment, the protruding portion 326 is located on the second hinge member 32 , and the protruding portion 326 is a rib 326 . The sliding groove 404 is located on the slide piece 40 , and the sliding groove 404 runs through the first groove body 401 and/or the second groove body 402 .

Here, the rib 326 is an arc-shaped rib with a certain length, and the chute 404 is an arc groove with the second rotation axis P2 as the central axis. "The chute 404 runs through the first groove body 401 and/or the second groove Body 402" means that the extension track of the chute 404 communicates with the first trough 401 and/or the second trough 402, and the rib 326 can slide in the chute 404 and enter the first trough 401 and/or the second trough Body 402.

When the sliding groove 404 passes through the first groove body 401, the convex rib 326 moves in the sliding groove 404 and passes through the first groove body 401, and the convex rib 326 cooperates with the first groove body 401 to limit the first shaft body 311, specifically The convex rib 326 cooperates with the end of the first groove body 401 to limit the first shaft body 311 , and the convex rib 326 is tangent to the outer contour of the first shaft body 311 .

The first chute 4041 and the second chute 4042 are staggered from each other, and the first chute 4041 extends to the second chute 4042. On both sides of a groove body 401 , the second sliding groove 4042 extends to both sides of the second groove body 402 , the side of the first shaft body 311 far away from the first hinge member 31 has a first notch 3111 , and the first notch 3111 is connected to the first notch 3111 A slide slot 4041 overlaps, and the side of the second shaft body 312 away from the first hinge member 31 has a second notch 3121 , and the second notch 3121 overlaps with the second slide slot 4042 .

The first rib 3261 passes through the first sliding groove 4041 and the first notch 3111 at the same time, and when the first rib 3261 slides to the end of the first sliding groove 4041, part of the first rib 3261 is located in the first notch 3111 While limiting the first shaft body 311, at the same time, the second rib 3262 passes through the second chute 4042 and the second notch 3121 at the same time, and when the second rib 3262 slides to the end of the second chute 4042, a part The second rib 3262 is located in the second notch 3121 to limit the second shaft body 312 .

In other embodiments, the protruding portion 326 and the slide groove 404 may have other structures.

For example, referring to Fig. 17 and Fig. 18, the protruding part 326 is located on the second hinge part 32, the protruding part 326 is a protruding post 326, the sliding slot 404 is located on the slide piece 40, the sliding slot 404 and the first groove body 401 are mutually staggered, and the sliding slot 404 and the second groove body 402 are staggered from each other.

At this time, when the second hinge member 32 rotates relative to the sliding piece 40, the boss 326 slides in the slide groove 404 until the boss 326 abuts against the end of the slide groove 404, and the positions of the slide groove 404 and the boss 326 can be adjusted. exchange.

Of course, in addition to the protrusion 326 and the sliding groove 404, the rotating assembly 50 can also be in other forms, for example, the second hinge 32 is provided with an elastic member, and the slide is provided with a limit hole, when the second hinge 32 is opposite to the slide When 40 rotates, the elastic piece slides on the bottom of the sliding plate until the elastic piece is limited in the limiting hole.

In this embodiment, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, that is, when the second hinge member 32 moves with the sliding piece 40 relative to the first hinge member 31, the door body 20 Includes multiple motion trajectories.

Referring to Fig. 19, in the first movement trajectory, the first shaft body 311 rotates in place in the first groove body 401 as the first rotation axis P1, and the second shaft body 312 rotates in the first groove body 401 with the first rotation axis P1 as the central axis.

P2 is that the central shaft continues to rotate in situ.

It should be noted that, in the first movement track, the second shaft body 312 and the second groove body 402 can be omitted, and only the first shaft body 311 rotates in the first groove body 401 to drive the door body 20 first. Rotate in situ with the first rotation axis P1 as the central axis.

Referring to Fig. 20, in the second movement trajectory, the first groove body 401 and the second groove body 402 are both in the shape of a strip, and when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the second groove body 401 The second axis body 312 moves in the second groove body 402 to drive the first axis body 311 to move in the first groove body 401 , and the door body 20 produces a translational amount relative to the box body 10 .

Here, "the amount of translation of the door body 20 relative to the box body 10" means that the door body 20 also has a translation amount during the process of rotating relative to the box body 10. When corresponding to a refrigerator, the translation amount refers to the amount of horizontal movement. That is, in addition to the door body 20 rotating relative to the box body 10 , the door body 20 also generates a horizontal movement relative to the box body 10 .

That is to say, during the entire opening process of the door body 20, the movement trajectory of the door body 20 is: the door body 20 first rotates and translates with the first rotation axis P1 as the central axis, and then the door body 20 switches to the second rotation axis P1. P2 is that the central shaft continues to rotate in situ.

Next, various specific examples of translation of the door body 20 will be introduced.

That is to say, the door body 20 first rotates at a certain angle, and then moves away from the cabinet 200 for a certain distance, so as to prevent the door body 20 from interfering with the cabinet 200 during the initial opening process.

Here, in a side-by-side refrigerator or a multi-door refrigerator with vertical beams, there are left and right doors arranged side by side, and the door body 20 is first rotated at a certain angle to prevent the left and right doors from interfering with each other.

In the third specific example, with reference to FIG. 22 , the first tank body 401 includes a first stop position A2, a second stop position A3, and an initial position A1 between the first stop position A2 and the second stop position A3. , the second groove body 402 includes the first segment L1, the second segment L2 and the third segment L3 connected in sequence. When the hinge assembly 30 is in the process of opening from the closed state to the first intermediate opening angle α11, the first shaft body 311 remains at the initial position A1, the second shaft body 312 takes the first shaft body 311 as the central axis and moves in the first section L1, when the hinge assembly 30 continues to open from the first intermediate opening angle α11 to the second intermediate opening angle During the process of α12, the second shaft body 312 moves in the second segment L2 to drive the first shaft body 311 to move from the initial position A1 to the first stop position A2, and the door body 20 faces the accommodation chamber D from the pivoting side P Moving, when the hinge assembly 30 is in the process of continuing to open from the second intermediate opening angle α12 to the first opening angle α1, the second shaft body 312 moves in the third section L3 and drives the first shaft body 311 from the first stop The position A2 moves to the second stop position A3, and the door body 20 moves from the accommodating chamber D toward the pivoting side P.

Here, when the door body 20 moves from the accommodating chamber D toward the pivoting side P, the opening of the box body 10 can be increased as much as possible under the premise of avoiding the mutual interference between the door body 20 and the cabinet 200, so as to prevent the door body 20 from obstructing the box body. The normal drawing of parts such as the drawer in the body 10, shelf.

It should be noted that the initial position A1, the first stop position A2 and the second stop position A3 are located on the same straight line, and the initial position A1 is the middle position between the first stop position A2 and the second stop position A3, that is, the initial position A1 and the first stop position There is a gap between the stop position A2 and the third stop position A3, but not limited thereto, the initial position A1 can coincide with the second stop position A3, or the initial position A1, the first stop position A2 and the second stop position A3 It can also lie on a different straight line.

Next, the specific working process of the hinge assembly 30 in the first embodiment will be introduced.

48 and 58 are schematic diagrams of a hinge assembly 30 with multiple shafts according to a second embodiment of the present invention.

Here, for the convenience of description, the same or similar structures are given the same or similar numbers, and will not be repeated hereafter.

The hinge assembly 30 includes two

shafts

311, 312 on the first hinge 31, two

grooves

401, 402 on the slide 40, a limit groove 322 on the second hinge 32, and a position between the slide 40 and the second hinge. A rotating assembly 50 between the two hinges 32 .

When the hinge assembly 30 is in the closed state, one of the shaft bodies 312 extends into one of the overlapping groove bodies 402 and the limiting groove 322, and the central axis of the shaft body 312 when rotating is the same as the central axis of the rotating assembly 50 when rotating do not coincide, wherein the other shaft body 311 extends into the other groove body 401, and the other shaft body 311 is located on the side of the second hinge member 32 close to the sliding piece 40, and the sliding piece 40 is opposite to the second hinge member 32 At rest, when the hinge assembly 30 is in the process of opening, the second hinge member 32 and the sliding piece 40 move relative to the first hinge member 31 until the

shafts

311, 312 are limited to the

grooves

401, 402, and then the rotating assembly 50 drives the second The hinge member 32 moves relative to the sliding piece 40 .

Here, "overlapping each other" means that the shape of the groove body 402 is consistent with that of the limiting groove 322; "the other shaft body 311 is located on the side of the second hinge member 32 close to the sliding piece 40" means that the shaft body 311 does not extend to The inside of the second hinge part 32, that is, the end of the shaft body 311 near the second hinge part 32 is located above the second hinge part 32 (that is, the side of the second hinge part 32 close to the slide plate 40), and the shaft body 311 is connected to the second hinge part 32. The hinge parts 32 themselves are not connected, but the connection between the shaft body 311 and the second hinge part 32 can also be realized through other structures, such as the protruding part 326 and the sliding groove 404 described later.

In this embodiment, the hinge assembly 30 includes a first shaft body 311 and a second shaft body 312 disposed on the first hinge member 31 , and a first groove body 401 and a second groove body 402 disposed on the sliding piece 40 . A groove body 401 cooperates with the first shaft body 311 , and a second groove body 402 cooperates with the second shaft body 312 .

Here, the second shaft body 312 extends to the overlapping limiting groove 322 and the second slot body 402 , and the first shaft body 311 extends to the first slot body 401 as an example for illustration.

In this embodiment, referring to FIG. 48 and FIG. 49 , the hinge assembly 30 further includes a relief groove 324 communicating with the limit groove 322 . Movement in slot 324.

Wherein, the relief groove 324 is an arc groove, and the center axis of the arc groove is the second rotation axis P2.

Here, the second hinge part 32 and the sliding piece 40 are actually matched by two parts, one part is the connection of the rotating assembly 50, and the other part is the second groove body 402 and the limiting groove 322 that cooperate with each other, wherein, Since the central axis of the limiting groove 322 is the first rotational axis P1 when rotating, and the central axis of the rotating assembly 50 is the second rotational axis P2, the second hinge member 32 cannot simultaneously use the first rotational axis P1 and the inconsistent position. The second rotation axis P2 rotates, that is, when the second shaft body 312 rotates in the limiting groove 322, the rotation assembly 50 cannot drive the second hinge member 32 to rotate relative to the sliding piece 40, that is to say, the second The hinge 32 and the slide 40 are relatively stationary.

Specifically, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the second shaft body 312 is located in the limiting groove 322, and due to the restriction effect of the second shaft body 312 on the limiting groove 322, the second shaft body 312 The second hinge member 32 cannot rotate relative to the sliding piece 40 with the second rotation axis P2 as the central axis, that is, the second hinge member 32 and the sliding piece 40 are relatively stationary. Movement in the limiting slot 322, the second hinge 32 and the sliding piece 40 can rotate relative to the first hinge 31 together until the first shaft 311 is limited to the first slot 401 and/or the second shaft 312 is limited to The second slot body 402 , at this time, the sliding piece 40 cannot continue to rotate relative to the first hinge member 31 , and the first hinge member 31 and the sliding piece 40 are mutually locked.

Then, when the hinge assembly 30 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, since the hinge assembly 30 also has a relief groove 324 communicating with the limit groove 322, the second shaft body 312 can The second rotation axis P2 is the central axis and moves in the relief groove 324, which can drive the second hinge member 32 to rotate relative to the sliding piece 40. At the same time, since the first shaft body 311 and the second hinge member 32 are spaced apart, the first The shaft body 311 does not hinder the rotation of the second hinge member 32 relative to the sliding piece 40 .

In addition, in this embodiment, through the cooperation of the second shaft body 312 and the rotating assembly 50, the mutual locking between the second hinge member 32 and the sliding piece can be realized. At this time, the structure of the second hinge member 32 can be simplified, and further realize Miniaturization of the overall structure of the hinge assembly 30 .

In this embodiment, referring to Fig. 48 and Fig. 49 , the rotating assembly 50 includes a third shaft 403 and a circular hole 325 located between the sliding plate 40 and the second hinge 32, and the third shaft 403 serves as the second rotating shaft. The shaft P2 rotates in the circular hole 325 .

Here, the second rotation axis P2 is a solid axis, the third shaft body 403 is located on the side of the slide 40 close to the second hinge 32 , and the round hole 325 is located on the second hinge 32 , when the second hinge 32 is opposite to the slide 40 When rotating, the third shaft body 403 rotates in place in the circular hole 325 , and the second shaft body 312 slides in the relief groove 324 .

In this embodiment, due to the poor limiting effect of the relief groove 324 on the second shaft body 312, when the rotating assembly 50 only includes the third shaft body 403 and the round hole 325, there may be a gap between the second hinge member 32 and the round hole 325. In order to avoid the phenomenon that the sliding pieces 40 shake each other, in this embodiment, the rotating assembly 50 is further provided with a protrusion 326 and a slide groove 404 , which can assist the second hinge member 32 to rotate relative to the sliding piece 40 stably.

In other embodiments, the rib 326 can directly limit the first shaft body 311 and/or the second shaft body 312 .

In this embodiment, the position limitation of the first shaft body 311 and/or the second shaft body 312 is realized through the cooperation of the rib 326 and the chute 404. In this way, when the door body 20 is closed by the maximum opening angle, only when the first shaft body When the body 311 and the second shaft body 312 are out of the limit of the rib 326, the sliding plate 40 can rotate, that is to say, when the door body 20 is closed by the maximum opening angle, it first passes through the rib 326 and enters the chute 404. The movement inside drives the second hinge member 32 to reset until the rib 326 breaks away from the first groove body 401 and/or the second groove body 402, and the limiting groove 322 overlaps with the second groove body 402, and then passes through the first shaft body The movement of the 311 in the first groove body 401 and the movement of the second shaft body 312 in the second groove body 402 and the limiting groove 322 drive the second hinge member 32 and the sliding piece 40 to reset together.

Here, the extending direction of the first protrusion 321 is consistent with the extending direction of the first groove body 401, that is to say, the extending direction of the first protrusion 321 is roughly the extending direction of the centerline of the first groove body 401, when the hinge assembly 30 When in the closed state, in the stacking direction of the first hinge 31 , the sliding piece 40 and the second hinge 32 , the first protrusion 321 roughly coincides with the center line of the first groove 401 , so when the first shaft 311 When sliding in the first groove body 401, the first shaft body 311 can slide relative to the first protrusion 321 at the same time, and there will be no relative movement between the first protrusion 321 and the first groove body 401 during the sliding process, that is, The second hinge member 32 and the sliding piece 40 can be kept relatively stationary.

Similarly, the extension direction of the second protrusion 322 is consistent with the extension direction of the second groove body 402 , other descriptions of the second protrusion 322 , the second groove body 402 , and the second shaft body 312 can refer to the above-mentioned first protrusion 321 , the description of the first tank body 401 and the first shaft body 311 will not be repeated here.

It can be seen that the first shaft body 311 is limited to the first groove body 401 and the first protrusion 321 at the same time, and the second shaft body 312 is limited to the second groove body 402 and the second protrusion 322 at the same time, so that when the first shaft body When the body 311 moves in the first groove body 401 and the second shaft body 312 moves in the second groove body 402, the second hinge member 32 and the sliding piece 40 can remain relatively stationary, that is, the second hinge member 32 can be controlled. It moves relative to the first hinge member 31 together with the sliding piece 40 .

In this embodiment, referring to FIG. 59 to FIG. 61, the first shaft body 311 includes two first protrusions 3111, and the two first protrusions 3111 cooperate to form the first slide groove 313, and the second shaft body 312 includes two The second protrusion 3121 , and the two second protrusions 3121 cooperate to form the second slide groove 314 .

Here, the first protrusion 3111 and the second protrusion 3121 are cylindrical protrusions.

In this way, when the first chute 313 moves relative to the first protrusion 321, in essence, the two first protrusions 3111 are located on both sides of the first protrusion 321 and slide relative to the first protrusion 321, which can reduce the first The frictional force between the sliding groove 313 and the first protrusion 321 prevents the first sliding groove 313 from being stuck with the first protrusion 321 during the sliding process and cannot continue to move relative to each other.

Similarly, when the second chute 314 moves relative to the second protrusion 322, the two second protrusions 3121 are actually located on both sides of the second protrusion 322 and slide relative to the second protrusion 322, which can reduce the The frictional force between the second sliding groove 314 and the second protrusion 322 prevents the second sliding groove 314 from being stuck with the second protrusion 322 during the sliding process and cannot continue to move relative to each other.

In this embodiment, the first shaft 311 further includes a first shaft body 3112 connected to the first hinge 31 , the second shaft 312 further includes a second shaft body 3122 connected to the first hinge 31 , two The first protrusion 3111 is located on a side of the first shaft body 3112 away from the first hinge 31 , and the two second protrusions 3121 are located on a side of the second shaft body 3122 away from the first hinge 31 .

Here, the first shaft body 3112 and the first groove body 401 cooperate with each other, and the diameter of the first shaft body body 3112 matches the opening width of the first groove body 401, which can prevent the first shaft body 311 from colliding with the first groove body 401. shaking each other.

Similarly, the second shaft body 3122 cooperates with the second groove body 402, and the diameter of the second shaft body body 3122 matches the opening width of the second groove body 402, which can prevent the second shaft body 312 from colliding with the second groove body. 402 shake each other.

Certainly, in other embodiments, referring to FIG. 62 , the two first protrusions 3111 and the two second protrusions 3121 can be directly connected to the first hinge member 31 .

In this embodiment, the hinge assembly 30 further includes a first extension 323 connected to the first protrusion 321 and a second extension 324 connected to the second protrusion 322 , when the second hinge 32 moves relative to the slide 40 , The first slide slot 313 slides relative to the first extension portion 323 , and the second slide slot 314 slides relative to the second extension portion 324 .

Both the first extension portion 323 and the second extension portion 324 are arc-shaped protrusions, and the central axis of the arc-arc protrusions is the second rotation axis P2.

Here, the second hinge member 32 and the sliding piece 40 are actually matched by two parts, one part is the connection of the rotating assembly 50, and the other part is the first groove body 401 and the first protrusion 321 that cooperate with each other. Cooperating second groove body 402 and second protrusion 322, wherein, since the first shaft body 311 rotates relative to the first protrusion 321 and the central axis of the second shaft body 312 when rotating relative to the second protrusion 322 is the first rotation axis P1, and the central axis when the rotation assembly 50 rotates is the second rotation axis P2, and the second hinge member 32 cannot simultaneously rotate with the first rotation axis P1 and the second rotation axis P2 whose positions are inconsistent, that is, when the first shaft body 311 When sliding at the first protrusion 321 (or the second shaft body 312 sliding at the second protrusion 322), the rotating assembly 50 cannot drive the second hinge member 32 to rotate relative to the sliding piece 40, that is, this The second hinge member 32 and the sliding plate 40 are relatively stationary during this time.

Specifically, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the first shaft body 311 passes through the first slide groove 313 and is limited to the first protrusion 321 (or the second shaft body 312 Through the second sliding groove 314 and limited to the second protrusion 322), due to the restriction of the first shaft body 311 on the first protrusion 321, the second hinge member 32 cannot relatively slide with the second rotation axis P2 as the central axis The sheet 40 rotates, that is, the second hinge member 32 and the slide sheet 40 are relatively stationary. At this time, through the movement of the first shaft body 311 in the first groove body 401 and the first protrusion 321 (or the movement of the second shaft body 312 in the first groove body 401 movement at the second groove 402 and the second protrusion 322), the second hinge 32 and the slide 40 can rotate relative to the first hinge 31 together until the first shaft 311 is limited to the first groove 401 and/or The second shaft body 312 is limited by the second groove body 402 . At this moment, the slide piece 40 cannot continue to rotate relative to the first hinge piece 31 , and the first hinge piece 31 and the slide piece 40 are mutually locked.

Then, when the hinge assembly 30 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, since the hinge assembly 30 also has the first extension 323 connecting the first protrusion 321 and the second protrusion 323 The second extension part 324 of 322 moves at the first extension part 323 through the first shaft body 311 with the second rotation axis P2 as the center axis, and the second shaft body 312 moves with the second rotation axis P2 as the center axis at the second The movement of the extension part 324 can drive the second hinge member 32 to rotate relative to the sliding piece 40 .

In this embodiment, continuing to refer to FIG. 59 to FIG. 61, the rotating assembly 50 includes a third shaft 403 and a round hole 325 located between the sliding plate 40 and the second hinge 32, and the third shaft 403 serves as the second rotating The shaft P2 rotates in the circular hole 325 .

Alternatively, the rib 326 only directly passes through the first shaft body 311 .

Specifically, referring to FIG. 64 , the side of the first shaft body 3112 far away from the first hinge 31 is also provided with a limit post 3113 , and the limit post 3113 cooperates with the first protruding post 3111 to form a gap through which the rib 326 can pass. The first shaft body 311 is limited by the gap (that is, the rib 326 passes through the first shaft body 311 ).

Alternatively, the rib 326 only directly passes through the second shaft body 312 .

Alternatively, the rib 326 directly passes through the first shaft body 311 and the second shaft body 312 at the same time.

Referring to Fig. 71 to Fig. 75, when the hinge assembly 30 is in the process of opening from the closed state to the first intermediate opening angle α11, the second hinge member 32 and the sliding piece 40 move relative to the first hinge member 31, and the first shaft body 311 remains at the initial position A1, the second shaft body 312 moves in the first section L1 with the first shaft body 311 as the central axis, and the door body 20 rotates in situ, wherein the first intermediate opening angle α11 is approximately 10°.

Referring to Fig. 76 to Fig. 80, when the hinge assembly 30 is in the process of continuing to open from the first intermediate opening angle α11 to the second intermediate opening angle α12, the second hinge member 32 and the sliding piece 40 continue to face the first hinge member 31 together. Movement, the second shaft body 312 moves in the second section L2 to drive the first shaft body 311 to move from the initial position A1 to the first stop position A2, and the door body 20 moves from the pivoting side P toward the receiving chamber D.

Referring to Fig. 81 to Fig. 85, when the hinge assembly 30 is in the process of continuing to open from the second intermediate opening angle α12 to the first opening angle α1, the second hinge member 32 and the sliding piece 40 continue to move together relative to the first hinge member 31 , the second shaft body 312 moves in the third section L3 to drive the first shaft body 311 to move from the first stop position A2 to the second stop position A3, and the door body 20 moves from the accommodation chamber D toward the pivoting side P, here , the first opening angle α1 is approximately 90°.

For other descriptions of the hinge assembly 30 of this embodiment, reference may be made to the first embodiment, and details are not repeated here.

With reference to FIG. 91 to FIG. 98 , it is a schematic diagram of a hinge assembly 30 with multiple grooves according to a fourth embodiment of the present invention.

The hinge assembly 30 includes two

shafts

311, 312 on the first hinge 31, two

grooves

401, 402 on the sliding piece 40, a limiting protrusion 322 on the second hinge 32, and two

grooves

401, 402 on the sliding piece 40 and Rotation assembly 50 between the second hinge member 32 .

One of the shafts 312 includes a sliding slot 314, the shaft 312 passes through one of the slots 402 and extends to the second hinge 32, the limiting protrusion 322 is limited to the sliding slot 314, and the center of the shaft 312 when rotating The shaft does not coincide with the central axis of the rotating assembly 50 when rotating, and the other shaft body 311 extends into the other slot body 401 , and the other shaft body 311 is located on a side of the second hinge member 32 close to the sliding piece 40 .

Here, the limiting protrusion 322 is a strip-shaped structure, and the limiting protrusion 322 can slide in the slide groove 314 to drive the relative movement between the second hinge member 32 and the shaft body 312 .

In addition, "the other shaft 311 is located on the side of the second hinge 32 close to the sliding piece 40" means that the shaft 311 does not extend to the inside of the second hinge 32, that is, the end of the shaft 311 near the second hinge 32 The part is located above the second hinge part 32 (that is, the side of the second hinge part 32 close to the sliding plate 40), and the shaft body 311 is not connected to the second hinge part 32 itself, but the shaft body 311 can also be realized by other structures. The connection with the second hinge member 32 is, for example, through the protruding portion 326 and the slideway 404 described later.

When the hinge assembly 30 is in the process of opening, one of the shafts 312 moves relative to one of the grooves 402 and the limit protrusion 322 and the other shaft 311 moves relative to the other groove 401 to drive the second hinge 32 Together with the sliding piece 40 , it moves relative to the first hinge member 31 until the

shafts

311 , 312 are limited to the

grooves

401 , 402 , and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40 .

Here, the extending direction of the limiting protrusion 322 is consistent with the extending direction of the groove body 402, that is to say, the extending direction of the limiting protrusion 322 is roughly the extending direction of the center line of the groove body 402, when the hinge assembly 30 is in the closed state , in the stacking direction of the first hinge 31 , the sliding piece 40 and the second hinge 32 , the stop protrusion 322 is roughly coincident with the center line of the groove 402 , so that when the shaft 312 slides in the groove 402 , The shaft body 312 can slide relative to the limiting protrusion 322 at the same time, and there is no relative movement between the limiting protrusion 322 and the groove body 402 during the sliding process, so that the second hinge member 32 and the sliding piece 40 remain relatively stationary .

It can be seen that the shaft body 312 is limited in the groove body 402 and the stop protrusion 322 at the same time, and the central axis when the shaft body 312 rotates does not coincide with the central axis when the rotating assembly 50 rotates, so that when the shaft body 312 is in the groove When moving inside the body 402 , the second hinge member 32 and the sliding piece 40 can remain relatively stationary, that is, the second hinge member 32 and the sliding piece 40 can be controlled to move relative to the first hinge member 31 .

Here, the second shaft body 312 extends to the overlapping limiting protrusion 322 and the second groove body 402 , and the first shaft body 311 only extends to the first groove body 401 as an example for illustration.

In this embodiment, referring to FIG. 91 and FIG. 92 , the second shaft body 312 includes two second protrusions 3121 , and the two second protrusions 3121 cooperate to form the second slide groove 314 .

Here, the second protrusion 3121 is a cylindrical protrusion.

In this way, when the second chute 314 moves relative to the second protrusion 322, essentially the two second protruding columns 3121 are located on both sides of the second protrusion 322 and slide relative to the second protrusion 322, which can reduce the second The frictional force between the sliding groove 314 and the second protrusion 322 prevents the second sliding groove 314 from being stuck with the second protrusion 322 during the sliding process and cannot continue to move relative to each other.

In this embodiment, the second shaft 312 further includes a second shaft body 3122 connected to the first hinge 31 , and the two second protrusions 3121 are located on the side of the second shaft body 3122 away from the first hinge 31 .

Here, the second shaft body 3122 cooperates with the second groove body 402, and the diameter of the second shaft body body 3122 matches the opening width of the second groove body 402, so that the second shaft body 312 and the second groove body 402 can be avoided. shaking each other.

Of course, in other embodiments, referring to FIG. 93 , the two second protrusions 3121 can be directly connected to the first hinge member 31 .

In this embodiment, the hinge assembly 30 further includes an extension portion 324 connected to the limiting protrusion 322 , and when the second hinge member 32 moves relative to the sliding piece 40 , the second sliding groove 314 slides relative to the extension portion 324 .

The extension portion 324 is an arc protrusion, and the central axis of the arc protrusion is the second rotation axis P2.

Here, the second hinge member 32 and the sliding piece 40 are actually matched by two parts, one part is the connection of the rotating assembly 50, and the other part is the second groove body 402 and the stop protrusion 322 that cooperate with each other, wherein Since the central axis of the second shaft body 312 when rotating relative to the stop protrusion 322 is the first rotating axis P1, and the central axis when the rotating assembly 50 is rotating is the second rotating axis P2, the second hinge member 32 cannot be positioned at the same time. Inconsistent rotation of the first rotation axis P1 and the second rotation axis P2 means that when the second shaft body 312 slides on the position-limiting protrusion 322 , the rotation assembly 50 cannot drive the second hinge member 32 to rotate relative to the sliding plate 40 . That is to say, at this moment, the second hinge member 32 and the sliding piece 40 are relatively stationary.

Specifically, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the second shaft body 312 passes through the second sliding groove 314 and is limited to the limit protrusion 322, because the second shaft body 312 Due to the limiting effect of the position-limiting protrusion 322, the second hinge member 32 cannot rotate relative to the sliding piece 40 with the second rotation axis P2 as the central axis, that is, the second hinge member 32 and the sliding piece 40 are relatively stationary. The movement of the shaft body 312 at the second groove body 402 and the stop protrusion 322, the second hinge member 32 and the sliding plate 40 can rotate relative to the first hinge member 31 together until the first shaft body 311 is limited in the first groove body 401 and/or the second shaft body 312 is limited in the second groove body 402 , at this time, the slide piece 40 cannot continue to rotate relative to the first hinge piece 31 , and the first hinge piece 31 and the slide piece 40 are locked to each other.

Then, when the hinge assembly 30 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, since the hinge assembly 30 also has an extension 324 connected to the stop protrusion 322, the second shaft body 312 can The second rotation axis P2 is the central axis and moves at the extension part 324, which can drive the second hinge member 32 to rotate relative to the sliding piece 40. The body 311 does not hinder the rotation of the second hinge member 32 relative to the sliding piece 40 .

In this embodiment, referring to FIG. 91 and FIG. 92 , the rotating assembly 50 includes a third shaft 403 and a round hole 325 located between the sliding plate 40 and the second hinge 32, and the third shaft 403 serves as the second rotating The shaft P2 rotates in the circular hole 325 .

Here, the second rotation axis P2 is a solid axis, the third shaft body 403 is located on the side of the slide 40 close to the second hinge 32 , and the round hole 325 is located on the second hinge 32 , when the second hinge 32 is opposite to the slide 40 When rotating, the third shaft body 403 rotates in place in the circular hole 325 , and the second shaft body 312 slides in the extension portion 324 .

In addition, the rotating assembly 50 further includes a protruding portion 326 and a sliding track 404 located between the sliding piece 40 and the second hinge member 32 , and the protruding portion 326 slides in the sliding track 404 with the second rotating axis P2 as a central axis.

At this time, when the second hinge member 32 rotates relative to the sliding piece 40, the third shaft body 403 rotates in situ in the circular hole 325, and the protruding part 326 slides in the slideway 404 with the second rotation axis P2 as the central axis. , which can improve the stability of the rotation of the second hinge member 32 relative to the sliding piece 40 .

In addition, when the protruding part 326 slides to the end of the slideway 404 in the slideway 404 (that is, when the protruding part 326 slides to the limit position), the first hinge part 32 cannot continue to rotate relative to the slide plate 40, and can pass through the slideway 404. The length of 404 controls the maximum opening angle of the door body 20, but not limited thereto.

In this embodiment, since the extension part 324 has a poor limiting effect on the second shaft body 312, when the rotating assembly 50 only includes the third shaft body 403 and the round hole 325, there may be a problem between the second hinge member 32 and the sliding hole. In order to avoid the phenomenon that the pieces 40 shake each other, in this embodiment, the rotating assembly 50 is further provided with a protruding part 326 and a slideway 404 , which can assist the second hinge member 32 to rotate relative to the sliding piece 40 stably.

In this embodiment, the protruding portion 326 is located on the second hinge member 32 , and the protruding portion 326 is a rib 326 . The slideway 404 is located on the sliding sheet 40 , and the slideway 404 runs through the first groove body 401 and/or the second groove body 402 .

Here, the rib 326 is an arc-shaped rib with a certain length, and the slideway 404 is an arc groove with the second rotation axis P2 as the central axis. "The slideway 404 runs through the first groove body 401 and/or the second groove The body 402" means that the extension track of the slideway 404 communicates with the first groove body 401 and/or the second groove body 402, and the rib 326 can slide in the slideway 404 and enter the first groove body 401 and/or the second groove body Body 402.

When the slideway 404 passes through the first groove body 401, the rib 326 moves in the slideway 404 and passes through the first groove body 401, and the rib 326 cooperates with the first groove body 401 to limit the first shaft body 311, specifically The convex rib 326 cooperates with the end of the first groove body 401 to limit the first shaft body 311 , and the convex rib 326 is tangent to the outer contour of the first shaft body 311 .

In other embodiments, the slideway 404 can also be directly located on the first shaft body 311 and/or the second shaft body 312, and the first shaft body 311 and/or the second shaft body can be directly realized through the cooperation of the rib 326 and the slideway 404 The limit of the body 312.
