Description

Technical Field

[0001] The utility model relates to the technical field of door opening mechanisms, in particular to a push-pull door mechanism facilitating wire routing. Background Art

[0002] Push-pull door mechanisms are commonly used in dishwashers with automatic door opening requirements. With the increasing intelligence of products in fields such as home appliances, the application of push-pull door mechanisms in products such as dishwashers and disinfection cabinets is becoming more and more extensive.

[0003] For a push-pull door mechanism with electrical components inside, the layout of connecting wires is a matter that needs to be considered as a whole. If the wire routing method is not arranged from the very beginning, it will become very difficult to route the wires later as other parts are installed. Different wire routing methods exist in various products, and products with more complex internal structures like push-pull door machines pay more attention to the wire routing method. The internal wire routing method has a great influence on the arrangement and structure of product parts.

[0004] A push-pull door mechanism usually includes a gear set, a rack, and microswitches located on both sides of the rack. The connecting wire needs to cross the rack and connect to the two microswitches. The traditional wire routing method is that the connecting wire routes from the bottom of the rack (i.e., the mating part of the rack and the housing guide rail). Such a wire routing method will damage the integrity of the sliding ribs at the bottom of the rack, and it is necessary to install clips to fix the connecting wire. The increase of clips makes the manufacturing difficulty also increase, and the manufacturing cost is increased. Summary of the Utility Model

[0005] In order to solve the technical problem that the connecting wire of the existing push-pull door mechanism routes from the bottom of the rack, which damages the integrity of the sliding ribs at the bottom of the rack and increases the manufacturing cost, the utility model provides a push-pull door mechanism facilitating wire routing to solve the above problems.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a push-pull door mechanism facilitating wire routing, including a housing assembly, a push rod assembly, at least two microswitches, a connecting wire, and a wire routing assembly. The housing assembly includes a housing and a housing cover that cooperate with each other; the push rod assembly is slidably matched with the guide rail inside the housing; the microswitches are respectively installed on both sides of the push rod assembly for detecting the minimum and maximum strokes of the push rod assembly; the connecting wire is installed inside the housing assembly on one side of the push rod assembly and is connected to the microswitch on the other side of the push rod assembly through the wire routing assembly; the wire routing assembly is used to guide and fix the connecting wire so that the connecting wire crosses the push rod assembly between the push rod assembly and the housing cover.

[0007] Further, the wire routing assembly includes a wire routing groove located on one side or both sides of the push rod assembly and fixed to the housing, and the notch of the wire routing groove faces the housing cover.

[0008] Further, the wire groove abuts against the shell cover.

[0009] Further, the interior of the shell has supporting ribs that are as high as the side wall of the shell, and the push rod assembly and the guide rail are located between the supporting ribs and the side wall of the shell.

[0010] Further, the wire groove is located on the supporting ribs and / or the side wall on one side of the push rod assembly.

[0011] Further, guiding blocks extending along the sliding direction perpendicular to the push rod assembly are provided on the supporting ribs and / or the side wall on one side of the push rod assembly. The guiding blocks are located between the push rod assembly and the shell cover in the height direction, and the wire groove is located at the top of the guiding blocks.

[0012] Further, the projected length of each guiding block on the push rod assembly is less than or equal to 1 / 4 of the width of the push rod assembly.

[0013] Further, the guiding blocks are integrally formed with the shell.

[0014] Further, the height of the wire groove is greater than or equal to the diameter of the connecting wire.

[0015] Further, the push rod assembly includes a rack, and sliding ribs are provided on the rack.

Specific embodiments

[0028] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0029] As Figures 1 - 4 shown, a push-pull door mechanism facilitating wire routing includes an outer shell assembly 1, a push rod assembly 2, at least two microswitches 3, a connection wire 4, and a wire routing assembly. The outer shell assembly 1 includes a mutually cooperating housing 101 and a housing cover 102, which are used to place other components therein to play an isolation and protection role. The housing 101 is separated into a plurality of installation positions by rib plates, and each component is placed in the designated installation position. The housing cover 102 is covered on the housing 101 to close the housing 101. The push rod assembly 2 is slidably matched with the guide rail 6 in the housing 101. The push rod assembly 2 is in a rod-shaped structure, and one end extends out of the outer shell assembly 1. The part located inside the outer shell assembly 1 is a rack 201 meshing with other transmission structures. The rack 201 is driven to slide reciprocally along the guide rail 6, so that the push rod assembly 2 extends outwards or retracts inwards. The microswitches 3 are respectively installed on both sides of the push rod assembly 2 and are used to detect the minimum stroke and the maximum stroke of the push rod assembly 2. The connection wire 4 is installed in the outer shell assembly 1 on one side of the push rod assembly 2 and is connected to the microswitch 3 on the other side of the push rod assembly 2 through the wire routing assembly. The wire routing assembly is used to guide and fix the connection wire 4, so that the connection wire 4 crosses the push rod assembly 2 between the push rod assembly 2 and the housing cover 102.

[0030] In the present utility model, the installation direction of the shell cover 102 and the shell body 101 is the up-and-down direction, and the shell cover 102 is located above the shell body 101, so the connecting wire 4 crosses above the push rod assembly 2. Since the matching structure between the rack 201 and the guide rail 6 in the push rod assembly 2 is located below the rack 201, the connecting wire 4 in the present utility model does not affect the integrity of the cooperation between the rack 201 and the guide rail 6.

[0031] The guiding of the connecting wire 4 by the wire routing assembly can be achieved but is not limited to the following structure:

[0032] As Figure 4 shown, the wire routing assembly includes a wire routing groove 11 located on one side or both sides of the push rod assembly 2 and fixed to the shell body 101. The notch of the wire routing groove 11 faces the shell cover 102, that is, the notch of the wire routing groove 11 faces upward. The wire routing groove 11 can hold the connecting wire 4 to fix the connecting wire 4. The inner bottom surface of the wire routing groove 11 can support the connecting wire 4, so that the connecting wire 4 is placed above the rack 201. The wire routing groove 11 can be provided only on one side of the push rod assembly 2, or wire routing grooves 11 can be provided on both sides of the push rod assembly 2. One wire routing groove 11 can be provided on one side of the push rod assembly 2, or multiple wire routing grooves 11 can be provided.

[0033] To prevent the connecting wire 4 from affecting the movement of the rack 201 after detaching from the wire routing groove 11, in a preferred embodiment, after the shell cover 102 is closed, the wire routing groove 11 abuts against the shell cover 102. Since the top surface of the shell body 101 abuts against the shell cover 102, the top of the wire routing groove 11 is flush with the top of the shell body 101. In a further design, the height of the wire routing groove 11 is preferably greater than or equal to the diameter of the connecting wire 4, so that the connecting wire 4 will not be squeezed after the shell cover 102 is closed, and it also avoids the difficulty in closing the shell cover 102.

[0034] There is usually also a support rib 7 with the same height as the side wall of the shell body 101 inside the shell body 101. The push rod assembly 2 and the guide rail 6 are located between the support rib 7 and the side wall of the shell body 101. The wire routing groove 11 is formed by machining in the fixing structure and is mainly arranged close to the push rod assembly 2 to support and limit the connecting wire 4 above the push rod assembly 2. For example, the wire routing groove 11 can be machined on the side wall of the shell body 101 or the support rib 7. However, the side wall of the shell body 101 or the support rib 7 is relatively thin and the guiding length is short, and the connecting wire 4 is prone to sag. In order to increase the guiding length of the wire routing groove 11, in a preferred embodiment of the present utility model, a guiding block 12 extending along the sliding direction perpendicular to the push rod assembly 2 is provided on the support rib 7 and / or the side wall on one side of the push rod assembly 2. The guiding block 12 is located between the push rod assembly 2 and the shell cover 102 in the height direction, and the wire routing groove 11 is located on the top of the guiding block 12. The guiding block can guide the connecting wire 4 along the width direction of the rack 201, increase the guiding length, and prevent the connecting wire 4 from sagging and colliding with the rack 201.

[0035] In the sliding door mechanism shown in the attached drawings of the present utility model, guiding blocks 12 are provided on both the supporting rib 7 and the side wall outside the housing 101. Each of the two guiding blocks 12 has a wire routing groove 11, as Figure 1 and Figure 4 shown. In order to minimize the length of the connection wire 4 above the rack 201, the two guiding blocks 12 are preferably arranged facing each other.

[0036] The guiding block 12 can be fixed to the housing 101 by welding or gluing, or can be integrally formed with the housing 101.

[0037] Since the guiding block 12 is located above the rack 201 and the guiding block 12 is fixed to the housing 101, the size of the guiding block 12 will affect the installation of the rack 201. In order to avoid the rack 201 being unable to be installed, the length dimension of the guiding block 12 (i.e., the dimension along the extending direction of the guiding block 12) cannot be too large. After verification, the projected length of each guiding block 12 on the push rod assembly 2 is less than or equal to 1 / 4 of the width of the push rod assembly 2. At this time, although the guiding block 12 reduces the width space above the push rod assembly 2, the push rod assembly 2 can pass through the guiding block 12 after being slightly tilted when it is separated from the guide rail 6.

[0038] The rack 201 on the push rod assembly 2 is in sliding fit with the guide rail 6, as Figure 4 and Figure 5 shown. A sliding rib 8 is provided at the bottom of the rack 201, and a sliding groove 9 for sliding fit with the guide rail 6 is formed between two adjacent sliding ribs 8. In the wire routing mode of the present utility model, the guide rail 6 and the sliding rib 8 can be continuously arranged along the length direction without being disconnected in the middle. Therefore, the sliding continuity is better and the structural strength is also better.

[0039] The layout position of the wire groove 11 on the housing 101 or the support rib 7 determines the routing length of the connecting wire 4. If the wire groove 11 is far from the microswitch 3, after the connecting wire 4 crosses the rack 201, it still needs to route along the side wall of the housing 101 or the support rib 7 towards the microswitch 3. Therefore, it is preferably to set the wire groove 11 near the microswitch 3. Taking the sliding door mechanism with two microswitches 3 as an example, the two microswitches 3 are respectively located on both sides of the rack 201. The inner cavity space of the housing 101 on the side where the support rib 7 is located is larger, and there is enough space to install the microswitch 3 and route the wire. While the space on the outer side wall of the housing 101 close to the rack 201 is smaller, an installation cavity 10 for accommodating the microswitch 3 needs to be set separately, and there is not enough space for the connecting wire 4 to route. If the wire groove 11 is set on this side, the wire groove 11 is preferably set at the connection between the side wall of the housing 101 and the installation cavity 10. At this time, after passing through the wire groove 11, the connecting wire 4 can directly enter the installation cavity 10, thereby reducing the routing length of the connecting wire 4 on this side. In a further design, a wire groove 5 (as shown in Figure 4 is provided at the connection between the side wall of the housing 101 and the installation cavity 10 and is communicated with the wire groove 11. The notch of the wire groove 5 faces the inside of the installation cavity 10. The connecting wire 4 passing through the wire groove 11 extends to the inner bottom surface of the installation cavity 10 under the guidance of the wire groove 5, so that the connecting wire 4 routes along the bottom surface in the installation cavity 10.

[0040] The wire routing structure of the present utility model is simple. The design of the wire groove 11 can avoid damaging the integrity of the sliding rib 8 of the rack 201 due to wire routing, and can also ensure that the connecting wire 4 will not fall off from the wire groove 11 and interfere with the movement of the rack 201.
