Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and in particular to a concealed three-degree-of-freedom large-range maintenance rotary door mechanism. Background Technology

[0002] Currently, during the inspection and maintenance of electronic equipment, technicians will conduct a comprehensive inspection of the electronic equipment, including checking the equipment's circuits, components, and connection lines, to ensure the normal operation and safety of the equipment. Therefore, a maintenance access door is usually reserved on the electronic equipment.

[0003] Currently, the electronic equipment repair doors use a hinged revolving door mechanism. This installation method and its function are illustrated in the attached diagram of the instruction manual. Figure 1 Figure 2 As shown, this method allows the maintenance door to open with only one degree of freedom, where... Figure 1 The diagram shown is a schematic of a single-degree-of-freedom maintenance revolving door structure that opens to the left and right. Figure 2 The diagram shows a current single-degree-of-freedom maintenance rotary door structure that opens and closes from top to bottom. As can be seen from the diagram, the opening range of the current single-degree-of-freedom maintenance rotary door structure is limited, which is inconvenient for removing modules in multi-module compact electronic equipment. In addition, hinged maintenance rotary door mechanisms generally need to be used in pairs or multiple pairs and installed on the outside, which requires a large installation space and affects the appearance of the entire equipment.

[0004] Based on this, in order to improve the opening and closing range of the existing maintenance rotary door and enhance the convenience of maintenance inside the housing after achieving a large opening and closing range, we propose a concealed three-degree-of-freedom large-range maintenance rotary door mechanism. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the limited opening range of maintenance doors with only one degree of freedom. Therefore, this invention proposes a concealed three-degree-of-freedom large-range maintenance revolving door mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a concealed, three-degree-of-freedom, wide-range maintenance rotary door mechanism, installed between the housing and the door. The mechanism includes a housing transition component and a door transition component, which are respectively used to connect to the housing and the door.

[0008] A sub-shaft seat is rotatably connected to the box transition piece, and a first rotational degree of freedom is formed between the sub-shaft seat and the box transition piece.

[0009] A female shaft seat is rotatably connected to the door transition piece, and a second rotational degree of freedom is formed between the female shaft seat and the door transition piece.

[0010] The mother shaft seat and the child shaft seat rotate relative to each other to form a third rotational degree of freedom.

[0011] Furthermore, the end face of the box transition piece is provided with a first mounting groove, and the end face of the door transition piece is provided with a second mounting groove.

[0012] Furthermore, both the sub-shaft seat and the mother shaft seat are I-shaped structures, with the upper and lower sides of the mother shaft seat sleeved on the outer sides of both ends of the sub-shaft seat, and the mother shaft seat is provided with a first rotating shaft through which the sub-shaft seat passes.

[0013] Furthermore, one end of the first rotating shaft has a first stop portion, and the other end has a threaded portion, which is threadedly connected to the lower side of the female shaft seat.

[0014] Furthermore, the upper and lower sides of the sub-shaft seat are sleeved on both ends of the box transition piece, wherein a second rotating shaft passing through the box transition piece is provided on the sub-shaft seat.

[0015] Furthermore, one end of the second rotating shaft has a second stop portion, and the second rotating shaft has a threaded portion that is threadedly connected to the lower side of the sub-shaft seat.

[0016] Furthermore, a clearance groove is provided on the upper side of the sub-shaft seat, and the second stop is located in the clearance groove.

[0017] Furthermore, the upper and lower sides of the female shaft seat are sleeved on the outer sides of both ends of the door transition piece, and a third rotating shaft passing through the door transition piece is also provided on the female shaft seat.

[0018] Furthermore, the top of the third rotating shaft has a third stop portion, and the bottom of the third rotating shaft also has a threaded portion, which is threadedly connected to the lower side of the female shaft seat.

[0019] Furthermore, countersunk holes are provided on the end faces of both the first and second mounting slots, and fasteners are placed inside the countersunk holes.

[0020] The present invention proposes a concealed three-degree-of-freedom large-range maintenance rotary door mechanism, which has the following advantages: By adopting a three-degree-of-freedom connection design, the present invention can achieve a large-angle opening and closing between the door and the housing, thereby expanding its spatial range of motion and correspondingly increasing the maintenance space, facilitating the removal and maintenance of various functional modules; in addition, considering the appearance issues of the rotary door mechanism installation, the three-degree-of-freedom rotary door mechanism of the present invention can be installed inside the cavity of the housing, meeting the concealment requirements. The overall structural design is simple, with a large opening range and convenient maintenance, making it particularly suitable for the maintenance of multi-module compact electronic equipment. Furthermore, the overall manufacturing cost of the present invention is relatively low, and assembly and installation are very convenient. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 3-8 As one embodiment of the present invention, a concealed three-degree-of-freedom large-range maintenance rotary door mechanism is disclosed. It is installed between the housing 1 and the door 2 to achieve a large-angle opening and closing of the door 2. This addresses the problems of limited space and numerous modules in current electronic equipment systems, where traditional maintenance rotary doors only have one degree of freedom, resulting in a relatively small rotation range. This restricts the ease of maintenance of various modules within the machine and the concealment and appearance of the rotary door mechanism. The electronic equipment described in this invention includes, but is not limited to, server chassis, electronic equipment, cabinets, test chambers, and modular shelters. Its economic benefits are considerable, especially suitable for rotary door locations with aesthetic requirements and limited space. It possesses advantages that traditional rotary door mechanisms cannot achieve. Specifically, in this embodiment, a server chassis is used as an example.

[0032] Reference Figure 3-6 Specifically, in this invention, the mechanism includes a box transition member 3 and a door transition member 4, which are respectively used to connect to the box body 1 and the door body 2:

[0033] A sub-shaft seat 5 is rotatably connected to the box transition member 3, and a first rotational degree of freedom is formed between the sub-shaft seat 5 and the box transition member 3;

[0034] A female shaft seat 6 is rotatably connected to the door transition piece 4, and a second rotational degree of freedom is formed between the female shaft seat 6 and the door transition piece 4.

[0035] The mother shaft seat 6 rotates with the child shaft seat 5 to form a third rotational degree of freedom.

[0036] In this invention, by adopting a three-degree-of-freedom connection design, a large-angle opening and closing between the door 2 and the housing 1 can be achieved, thereby expanding its spatial range of motion and correspondingly increasing the maintenance space, facilitating the removal and maintenance of each functional module; in addition, based on the appearance problem of the rotating door mechanism installation, the three-degree-of-freedom rotating door mechanism of this invention can be installed inside the cavity of the housing 1 to meet the concealment requirements. This invention can solve the above problems.

[0037] Reference Figure 4 In some embodiments, the end face of the box transition piece 3 is provided with a first mounting groove 31, and the end face of the door transition piece 4 is provided with a second mounting groove 41. Specifically, in this invention, both the first mounting groove 31 and the second mounting groove 41 are rectangular grooves. That is, in the embodiments of this invention, the box transition piece 3 and the door transition piece 4 are designed as a U-shaped structure with concentric circular through holes symmetrically provided at both ends. These concentric circular through holes are used for the shaft to pass through. The end faces of the first mounting groove 31 and the second mounting groove 41 are provided with countersunk holes. Fasteners are placed inside the countersunk holes. The fasteners are preferably countersunk bolts. During installation, the box transition piece 3 and the door transition piece 4 are respectively installed and fixed on the box body 1 and the door body 2 by the fasteners. The installation operation is simple and convenient.

[0038] Reference Figure 4 , 5Based on the above embodiments, in this embodiment, both the sub-shaft seat 5 and the female shaft seat 6 are I-shaped structures. Obviously, taking the height direction of the housing 1 as an example, the I-shaped structure consists of three parts: the upper side, the lower side, and the middle part. In this embodiment, the above three parts can be designed as an integral molding. Of course, in other embodiments, a fixed design with separate assembly can also be adopted. It should be noted that the description of the above parts will continue in the following invention, namely the upper side, the lower side, and the middle part. The upper and lower sides of the female shaft seat 6 are sleeved on the outer sides of the two ends of the sub-shaft seat 5. The female shaft seat 6 is provided with a first rotating shaft 7 that passes through the sub-shaft seat 5. Specifically, in this embodiment, the upper and lower sides of one side of the sub-shaft seat 5 are provided with The first rotating shaft 7 passes through two opposite circular holes. Furthermore, a circular hole and a threaded component are respectively provided on the upper and lower sides of one side of the mother shaft seat 6. The threaded component can be a threaded hole or a nut. Specifically, the diameter of the circular hole is not less than the diameter of the first rotating shaft 7. Preferably, in this embodiment, the diameter of the circular hole is 0.3 mm larger than the diameter of the first rotating shaft 7. That is, in this embodiment, the first rotating shaft 7 is inserted sequentially through the circular hole of the mother shaft seat 6 into the upper and lower circular holes of the daughter shaft seat 5. Then, the bottom of the first rotating shaft 7 is threaded to the lower side of the mother shaft seat 6, thus achieving the connection and rotation between the daughter shaft seat 5 and the mother shaft seat 6. Obviously, this rotation is the aforementioned third degree of rotational freedom.

[0039] Reference Figure 4 Furthermore, one end of the first rotating shaft 7 has a first stop portion 71, and the other end has a threaded portion. The threaded portion is threadedly connected to the lower side of the female shaft seat 6. Considering the ease of rotation of the first rotating shaft 7, in this embodiment, a portion of material can be symmetrically milled away from the outside of the first stop portion 71 to form two flat portions, which can be tightened with a U-shaped wrench.

[0040] Referring to 3-5, based on the above embodiments, in this invention, the upper and lower sides of the sub-shaft seat 5 are sleeved on both ends of the box transition member 3, wherein a second rotating shaft 8 is provided on the sub-shaft seat 5 and passes through the box transition member 3.

[0041] Reference Figure 4Specifically, one end of the second rotating shaft 8 has a second stop 81, and the second rotating shaft 8 has a threaded part, which is threadedly connected to the lower side of the sub-shaft seat 5. Of course, those skilled in the art will know that in this embodiment, a round hole can also be provided on the upper side of the sub-shaft seat 5, and a threaded part can be provided on its lower side. Since a concentric round through hole is provided on the end face of the box transition piece 3, the second rotating shaft 8 can be inserted along the round hole above the sub-shaft seat 5 during installation. After passing through the box transition piece 3, it is then connected to the threaded part on its lower side, thus completing the connection and rotation between the sub-shaft seat 5 and the box transition piece 3. Obviously, this rotation is the first rotational degree of freedom mentioned above.

[0042] Reference Figure 4 In addition, to avoid interference between the top of the second rotating shaft 8 and the mother shaft seat 6 during rotation, an avoidance groove 51 is provided on the upper side of the sub-shaft seat 5 in this embodiment of the invention. The second stop part 81 is located in the avoidance groove 51. The avoidance groove 51 is a rectangular groove. Preferably, in this embodiment, the depth of the avoidance groove 51 is the same as the height of the second stop part 81 to ensure the consistency of appearance after installation.

[0043] Based on the above embodiments, the upper and lower sides of the female shaft seat 6 in this invention are sleeved on the outer sides of both ends of the door transition piece 4, and a third rotating shaft 9 that penetrates the door transition piece 4 is also provided on the female shaft seat 6.

[0044] Reference Figure 4 Furthermore, the top of the third rotating shaft 9 has a third stop 91, and the bottom of the third rotating shaft 9 also has a threaded part, which is threadedly connected to the lower side of the female shaft seat 6. Of course, in this embodiment, a round hole and a threaded part can also be provided on the upper and lower sides of the other side of the female shaft seat 6, respectively. During installation, they are connected through the third rotating shaft 9, so that the connection rotation between the female shaft seat 6 and the door transition piece 4 can be realized. Obviously, this rotation is the second rotational degree of freedom mentioned above.

[0045] In summary, the structure involved in this invention can achieve three degrees of freedom, namely rotational degrees of freedom: between the door transition piece 4 and the mother shaft seat 6, between the mother shaft seat 6 and the daughter shaft seat 5, and between the daughter shaft seat 5 and the box transition piece 3. To achieve these three rotational degrees of freedom, the first rotating shaft 7, the second rotating shaft 8, and the third rotating shaft 9 need to cooperate with each other. The door transition piece 4 and the door body 2, and the box transition piece 3 and the inner wall of the box body 1 are fixedly connected by countersunk screws. In terms of spatial mechanisms, mechanisms with more degrees of freedom have a relatively larger opening and closing space, and the maintenance door can be opened to a relatively larger extent, which facilitates the removal and maintenance of various functional modules within the equipment.

[0046] Specifically, when using it:

[0047] Reference Figure 7 , 8 Since the door body 2 and the door transition piece 4 are rigidly connected by countersunk screws, when the door body 2 is opened, the door transition piece 4 will be pulled outward, which will give the main shaft seat 6 an outward driving torque. Under the action of this driving torque, the main shaft seat 6 and the door transition piece 4 will rotate, and the main shaft seat 6 will be pulled outward. At the same time, a driving torque will be given to the sub-shaft seat 5. Under the action of this driving torque, the sub-shaft seat 5 and the box transition piece 3 will be pulled to rotate, thus completing the opening operation of the door body 2. Conversely, the closing operation of the door body 2 is completed.

[0048] The assembly and installation steps of the maintenance revolving door mechanism of this invention are as follows: Connect and tighten the main shaft seat 6 and the door transition piece 4 via the third rotating shaft 9 to ensure flexible rotation between them; based on the previous step, connect and tighten the main shaft seat 6 and the sub-shaft seat 5 via the first rotating shaft 7 to ensure flexible rotation between them; based on the previous step, connect and tighten the sub-shaft seat 5 and the box transition piece 3 via the second rotating shaft 8 to ensure flexible rotation between them; through the above steps, the assembly of this mechanism is completed.

[0049] Reference Figure 7 , 8 The assembled three-degree-of-freedom revolving door mechanism is then installed onto the door body and housing 1 respectively. The steps are as follows: first, the housing transition piece 3 is fixed to the corresponding side wall of housing 1 with countersunk screws to ensure that the fixation is secure; the next step is to fix the door transition piece 4 to the corresponding maintenance revolving door, i.e., door body 2, with countersunk screws to ensure that the fixation is secure; the above assembly and installation steps complete the relevant work. If disassembly is required, the process is reversed.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
