DETAILED DESCRIPTION

[0051] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0052] Embodiment 1:

[0053] See also Figures 1 to 13 As shown, this embodiment provides a switch cabinet door mechanism, comprising: an outer shell 1, a rack 2 disposed in the outer shell 1, one end of which is connected to the door body 200 to be suitable for sliding the door body 200, and a power assembly connected to the rack 2 to drive the rack 2 to perform linear reciprocating motion. One end of the rack 2 extends out of the outer shell 1 to facilitate connection with the door body 200.

[0054] Specifically, first, a toothed portion 21 is provided on the bottom end surface of the rack 2 along its length direction; it should be noted that the bottom end surface of the rack 2 here corresponds to its use orientation in the switch cabinet door mechanism. Under this design, when the switch cabinet door mechanism realizes the opening and closing movement of the door body 200 relative to the cabinet body 100, the user will not directly observe the toothed portion 21, thereby improving the overall aesthetics of the switch cabinet door mechanism, and improving the safety of the switch cabinet door mechanism during use, thereby improving the user's satisfaction during use.

[0055] Next, the power assembly includes a slipping gear 32 adapted to be meshed and connected with the toothed portion 21 from the bottom end of the rack 2, and a driving gear 31 connected to the slipping gear 32 adapted to drive the slipping gear 32 to rotate; that is, the driving gear 31 and the slipping gear 32 form a gear slipping structure 3 that can slip relatively. Of course, the driving gear 31 here is also connected to a driver for driving its rotation, and any mature means in the prior art can be selected for the driver, and this embodiment does not make an absolute limitation on this. In addition, an assembly cavity for assembling the driving gear 31 and the slipping gear 32 is formed in the outer shell 1.

[0056] Based on the above structure, generally speaking, when the slipping gear 32 does not slip relative to the driving gear 31, the slipping gear 32 rotates under the drive of the driving gear 31 and transmits power to the rack 2; when the rack 2 is subjected to a large external force and causes the slipping gear 32 to slip relative to the driving gear 31, the slipping gear 32 rotates under the action of the rack 2, and the driving gear 31 does not rotate with it.

[0057] In order to realize the above two different matching states between the slipping gear 32 and the driving gear 31, this embodiment will now be described in detail with reference to the accompanying drawings by taking an example of a specific slipping matching structure:

[0058] First, generally speaking, a hollow accommodating cavity suitable for partial insertion of the slipping gear 32 is formed in the driving gear 31; and a spring body 33 is also provided between the outer wall of the portion where the slipping gear 32 is inserted into the hollow accommodating cavity and the cavity wall of the hollow accommodating cavity; the hollow accommodating cavity and the slipping gear 32 are suitable for jointly forming an axial limit for the spring body 33 so that the spring body 33 is in a slightly pre-tightened state.

[0059] Furthermore, in more detail, the slipping gear 32 includes a toothed main body portion 322 for meshing with the toothed portion 21, and a hook portion provided at one of the axial side ends of the toothed main body portion 322 for fitting the spring body 33; wherein the hook portion includes a plurality of cantilever hooks 326 arranged at intervals along the circumferential direction; the length of each cantilever hook 326 is the same and the end thereof away from the toothed main body portion 322 is a movable end.

[0060] Based on the above situation, it is also necessary to explain that each cantilever hook 326 has a hook head formed at one end away from the toothed main body 322; the hook head is outwardly turned relative to the axis of the slipping gear 32 to limit an axial side end of the spring body 33.

[0061] Furthermore, a slip-fitting portion for contacting and cooperating with the driving gear 31 is provided between the tooth-shaped main body portion 322 and the hook portion, and a slip-supporting portion for contacting and cooperating with the slip-fitting portion is provided in the corresponding hollow accommodation cavity of the driving gear 31 .

[0062] An optional embodiment is given by way of example in conjunction with the accompanying drawings, in which the slipping support portion includes a protruding annular contact portion 314 in the hollow accommodating cavity of the driving gear 31, an annular contact platform 315 formed at one axial side end of the annular contact portion 314 facing the hollow accommodating cavity, and an annular limit platform 316 formed at the other axial side end of the annular contact portion 314 facing the hollow accommodating cavity; wherein the annular contact platform 315 is suitable for contacting with the slipping mating portion; and the annular limit platform 316 is used for axially limiting the axial side end of the spring body 33 toward the toothed main body portion 322.

[0063] The slipping mating part includes an annular slipping part 324 for contacting and mating with the annular contact platform 315, and an annular connecting part 323 located on the side of the annular slipping part 324 facing away from the hook part for contacting and mating with the wall surface 313 of the hollow accommodating cavity. In this way, the center of the slipping gear 32 is collinear with the center of the driving gear 31, ensuring the coaxiality of the two when they rotate synchronously.

[0064] Among them, the contact surface formed between the annular slipping portion 324 and the annular contact platform 315 is an annular wave surface; when the wave crest of the annular slipping portion 324 meshes with the wave trough of the annular contact platform 315, the slipping gear 32 and the driving gear 31 are suitable for synchronous rotation; when the wave crest of the annular slipping portion 324 and the wave trough of the annular contact platform 315 produce relative sliding, the slipping gear 32 performs a slipping rotation relative to the driving gear 31.

[0065] More specifically, one end of the spring body 33 cooperates with the annular limit platform 316 of the driving gear 31, and the other end cooperates with the cantilever hook 326 of the slipping gear 32. Through the limiting compression of the spring body 33 by the two, the spring body 33 has a certain elasticity. In this way, under the action of the elastic force, the slipping gear 32 and the driving gear 31 can always be in a tightly held state. At the same time, the cooperation of the annular wave surface formed by the two ensures that the slipping gear 32 and the driving gear 31 can maintain synchronous rotation under normal conditions.

[0066] The annular contact platform 315 of the driving gear 31 contacts and cooperates with the annular slipping portion 324 of the slipping gear 32. Under normal circumstances, under the elastic force of the spring body 33, the wave crest of the annular contact platform 315 contacts and cooperates with the wave trough of the annular slipping portion 324, and the wave trough of the annular contact platform 315 contacts and cooperates with the wave crest of the annular slipping portion 324, so that the two will not rotate relative to each other under normal force. Under the drive of external force, the slipping gear 32 overcomes the elastic force of the spring body 33 and the annular wave surface that cooperates with the driving gear 31, that is, the wave crest of the annular slipping portion 324 of the slipping gear 32 separates from the wave trough of the annular contact platform 315 of the driving gear 31, and passes over its wave crest, and cooperates with the next wave trough under the elastic force of the spring body 33. At this time, if the external force continues to act, the slipping gear 32 continues to slide.

[0067] In addition, in order to further improve the stability of the contact and fitting state formed by the slipping gear 32 and the driving gear 31, the annular contact portion 314 in this embodiment is also suitable for contacting with the slipping fitting portion; and the corresponding slipping fitting portion also includes an annular adapter portion 325 located on the side of the annular slipping portion 324 facing the hook portion and used for contacting and fitting with the inner wall surface of the annular contact portion 314.

[0068] The wall surface 313 of the hollow accommodating cavity of the driving gear 31 cooperates with the annular connecting portion 323 of the slipping gear 32, and the annular contact portion 314 cooperates with the annular adapter portion 325, so that when the slipping gear 32 produces a slipping action relative to the driving gear 31, it can not only ensure the realization of slipping rotation, but also ensure the coaxiality of the slipping gear 32 and the driving gear 31 during the slipping process.

[0069] Finally, it is necessary to explain that the active gear 31 also includes an active toothed portion 311 formed on its outer surface and a first rotating surface 312 located at one axial side end of the active toothed portion 311, and a second rotating surface 318 located at the other axial side end of the active toothed portion 311. And the slipping gear 32 also includes a third rotating surface 321 located at the axial side end of the toothed main body portion 322 facing away from the hook portion. The assembly cavity of the outer shell 1 is formed with a first supporting groove 11, a second supporting groove 12, a third supporting groove 13, a first chamber 14 and a second chamber 15. The second rotating surface 318, the first rotating surface 312 of the driving gear 31 and the third rotating surface 321 of the slipping gear 32 are respectively in contact with the first supporting groove 11, the second supporting groove 12 and the third supporting groove 13 of the shell, and at the same time, the driving toothed portion 311 of the driving gear 31 and the toothed main body portion 322 of the slipping gear 32 are respectively placed in the first chamber 14 and the second chamber 15 of the shell, thereby completing the cooperation between the slipping gear 32 and the driving gear 31 and the shell respectively; at the same time, the toothed portion 21 of the rack 2 is meshed with the toothed main body portion 322 of the slipping gear 32, thereby completing the transmission cooperation between the rack 2 and the slipping gear 32 device.

[0070] In summary, for the switch cabinet door mechanism of this embodiment, its specific implementation principle is as follows:

[0071] The first one is that when the switch cabinet door mechanism is in normal use, there is no slipping between the slipping gear 32 and the driving gear 31, that is, the driving gear 31 and the slipping gear 32 rotate synchronously, so that the slipping gear 32 can be driven to rotate by driving the driving gear 31 to finally control the extension and retraction movement of the rack 2, and realize the automatic opening and closing of the door body 200 relative to the cabinet body 100.

[0072] The second is when the rack 2 is subjected to an abnormal external force. Fig.13 When a positive or reverse external force F is applied, when the force is greater than the elastic force of the spring body 33 after compression, in order to protect the overall structure of the switch cabinet door mechanism, the rack 2 drives the slipping gear 32 to rotate relative to the driving gear 31.

[0073] Embodiment 2:

[0075] It should be noted that the household appliance referred to in this embodiment may be a dishwasher or other household appliances whose cabinets 100 and doors 200 need to be automatically opened and closed, and this embodiment does not make an absolute limitation on this.
