Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a control box and a host. Background Technology

[0002] In industrial control equipment, home appliances, and other fields, control panels are typically mounted inside the equipment head using screws. For example, in the mounting structure of an oven stove control panel, screws are used to fix the panel to a panel bracket. This type of solution is widely used in products such as washing machines and air conditioner controllers.

[0003] During the control panel installation process described above, screw installation requires tools such as electric screwdrivers, which is inefficient and carries risks such as stripped screws or missed screws. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a control box and a host, which effectively solves the problems of low efficiency and risks such as stripped screws and missing screws caused by the screw installation of existing control panels.

[0005] The above-mentioned technical problems are solved by the following technical solutions:

[0006] A control box, comprising:

[0008] The box body has a cavity for accommodating the shell, and an opening is provided on one side of the box body; the box body has a first slot on each of the opposite sides adjacent to the opening side;

[0009] After the shell is inserted into the cavity of the box, the first elastic pressure arm engages with the first slot, and the second elastic pressure arm abuts against the inner plate surface of the box.

[0010] Compared with the prior art, the control box described in this utility model has the following advantages:

[0011] The control box provided by this utility model features a drawer unit. When the drawer unit is inserted into the cavity of the box body, the first elastic pressure arms on the left and right side walls engage with the first slots on opposite sides of the box body near the opening. The locking force generated by elastic deformation positions and centers the drawer unit within the box body, preventing it from swaying left and right. The second elastic pressure arm on the inner panel abuts against the rear side wall of the cavity, using elastic thrust to keep the drawer unit tightly against the front panel of the cavity, ensuring a stable installation of the drawer unit in the front-back direction. This working method, which uses the locking of the first elastic pressure arm with the first slot and the abutment of the second elastic pressure arm with the rear side wall of the cavity, eliminates the need for screws to install and secure the drawer unit to the box body, greatly improving installation efficiency. It also avoids the risk of damaging internal components when using screws and facilitates later maintenance and disassembly.

[0013] The second elastic pressure arm includes a second pressure arm body and a second abutting section disposed at one end of the second pressure arm body. The other end of the second pressure arm body is connected to the shell extraction shell. The second abutting section gradually approaches the shell extraction shell from the end connected to the second pressure arm body to the other end.

[0014] In one embodiment, each of the second elastic pressure arms has a sidewall that is flush with the inner sidewall of the side of the shell where the first through groove is provided. The left and right sidewalls of the shell are respectively provided with first through grooves that correspond one-to-one with the first elastic pressure arms. The orthogonal projection of the first elastic pressure arm toward the shell falls into the first through groove.

[0015] In one embodiment, the inner plate of the shell is provided with a second through groove corresponding to the second elastic pressure arm, and the second through groove is used to provide elastic deformation space for the second elastic pressure arm.

[0016] In one embodiment, the left and right sidewalls of the shell are respectively provided with a plurality of the first elastic pressure arms.

[0017] In one embodiment, the inner plate surface of the shell is provided with a plurality of second elastic pressure arms, which are spaced apart along the length direction of the shell.

[0018] In one embodiment, both the first elastic pressure arm and the second elastic pressure arm are integrally formed with the shell extraction.

[0019] In one embodiment, the top of the housing is provided with a wire outlet hole, which is suitable for the circuit board wiring to pass through.

[0020] Secondly, this utility model also provides a host, including a housing and a control box, wherein the control box is installed in the housing;

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] In industrial control equipment, home appliances, and other fields, control panels are typically installed inside the equipment head using screws. However, screw installation requires tools such as electric screwdrivers, which is inefficient and carries risks such as stripped screws or missed screws.

[0035] This embodiment provides a control box that effectively solves the problem of existing control panels requiring screw installation. This control box improves installation efficiency, facilitates maintenance, and reduces the risk of damaging the control panel when screwing in screws.

[0036] like Figures 1 to 4 As shown, the control box provided in this embodiment includes a drawer 1 and a box body 4. The left and right side walls of the drawer 1 are respectively provided with first elastic pressure arms 2, and the inner plate surface of the drawer 1 is provided with second elastic pressure arms 3. The box body 4 has a cavity with an opening on at least one side. The left and right side walls of the cavity are respectively provided with first slots 41. When the drawer 1 is inserted into the cavity of the box body 4, the first elastic pressure arms 2 are engaged with the first slots 41, and the second elastic pressure arms 3 abut against the rear side wall of the cavity.

[0037] like Figures 1 to 4As shown in the figure, in the control box provided in this embodiment, when the drawer 1 of the control box is inserted into the cavity of the box body 4, the first elastic pressure arms 2 on the left and right side walls will engage with the first slots 41 on opposite sides of the box body 4 near the opening. The engagement force generated by the elastic deformation realizes the positioning and centering of the drawer 1 in the box body 4, preventing the drawer 1 from swaying left and right. The second elastic pressure arm 3 on the inner panel abuts against the rear side wall of the cavity, and uses elastic thrust to make the drawer 1 fit tightly against the front panel of the cavity, ensuring the stable installation of the drawer 1 in the front-back direction. This working method, which uses the engagement of the first elastic pressure arm 2 with the first slot 41 and the abutment of the second elastic pressure arm 3 with the rear side wall of the cavity, can complete the installation and fastening of the drawer 1 and the box body 4 without the use of screws, improving installation efficiency, avoiding the risk of damaging internal components by using screws, and facilitating later maintenance and disassembly.

[0038] In one embodiment, the first elastic pressure arm 2 includes a first pressure arm body 21 and a first abutting section 22 disposed at one end of the first pressure arm body 21. The other end of the first pressure arm body 21 is connected to the drawer 1, and the first abutting section 22 gradually approaches the drawer 1 from the end connected to the first pressure arm body 21 to the other end. The second elastic pressure arm 3 includes a second pressure arm body 31 and a second abutting section 32 disposed at one end of the second pressure arm body 31. The other end of the second pressure arm body 31 is connected to the drawer 1, and the second abutting section 32 gradually approaches the drawer 1 from the end connected to the second pressure arm body 31 to the other end. In other embodiments, only the first pressure arm body 21 and the first abutting section 22 may be provided on the first elastic pressure arm 2, or only the second pressure arm body 31 and the second abutting section 32 may be provided on the second elastic pressure arm 3.

[0039] like Figure 1 and Figure 4 As shown, the first pressure arm body 21 is a long strip-shaped structure, with its root connected to the side wall of the shell 1. The first abutting section 22 gradually approaches the shell 1 from one end connected to the first pressure arm body 21 to the other end, so that the end of the first elastic pressure arm 2 forms a "hook-shaped" protrusion. In use, the first pressure arm body 21 serves as the main elastic deformation area. The transition between the first abutting section 22 and the first pressure arm body 21 is used to engage in the first slot 41 of the box body 4. Since the transition between the first abutting section 22 and the first pressure arm body 21 is bent, the transition between the first abutting section 22 and the first pressure arm body 21 can be easily removed from the first slot 41 of the box body 4 when disassembling the shell 1, that is, the shell 1 can be easily pulled out from the inside of the box body 4.

[0040] like Figure 2 and Figure 3As shown, the second pressure arm body 31 is also a long strip-shaped structure. The root of the second pressure arm body 31 is fixed to the inner plate of the drawer 1. The second abutting section 32 gradually approaches the drawer 1 from one end connected to the second pressure arm body 31 to the other end, so that the transition between the second abutting section 32 and the second pressure arm body 31 is bent. When the drawer 1 is installed inside the box 4, the transition between the second abutting section 32 and the second pressure arm body 31 is used to abut against the rear wall of the box 4 to force the second pressure arm body 31 to produce elastic deformation. At the same time, when the drawer 1 is disassembled, the second abutting section 32 abuts against the box 4, which makes it easy to pull the drawer 1 out from the inside of the box 4.

[0041] In one embodiment, the left and right sidewalls of the shell 1 are respectively provided with first through grooves 11 corresponding to the first elastic pressure arms 2, and the orthogonal projection of the first elastic pressure arms 2 toward the shell 1 falls into the first through grooves 11.

[0042] like Figure 1 and Figure 2 As shown, the left and right sidewalls of the drawer 1 are respectively provided with first through grooves 11, which correspond to the positions of the first elastic pressure arm 2, that is, the first through grooves 11 are located on the bending deformation side of the first elastic pressure arm 2. When the first elastic pressure arm 2 is compressed and undergoes elastic deformation, the presence of the first through grooves 11 can provide space for the elastic deformation of the first elastic pressure arm 2. Specifically, when the drawer 1 is inserted into the box body 4, the first elastic pressure arm 2 is compressed by the inner wall of the box body 4 and bends towards the first through groove 11. If the gap between the sidewall of the drawer 1 and the inside of the box body 4 is small, then when the drawer 1 is inserted into the box body 4, the first elastic pressure arm 2 will enter the first through groove 11.

[0043] In one embodiment, each of the second elastic pressure arms 3 has a sidewall that is flush with the inner sidewall of the side of the shell 1 where the first through groove 11 is provided. The inner plate surface of the shell 1 is provided with a second through groove 12 that corresponds one-to-one with the second elastic pressure arm 3. The second through groove 12 is used to provide elastic deformation space for the second elastic pressure arm 3.

[0044] like Figure 1 As shown, each of the second elastic pressure arms 3 has a sidewall flush with the inner sidewall of the side of the drawer 1 where the first through groove 11 is provided. Specifically, the outer sidewall of the second elastic pressure arm 3 is flush with the inner sidewall of the side of the drawer 1 where the first through groove 11 is provided, so that the second elastic pressure arm 3 is positioned close to the sidewall of the drawer 1 where the first through groove 11 is provided, and a second through groove 12 corresponding to the second elastic pressure arm 3 is formed on this sidewall. When the drawer 1 is installed, during the process of the drawer 1 being inserted into the box 4, the second elastic pressure arm 3 is squeezed by the inner wall of the box 4 and bends towards the second through groove 12. The second elastic pressure arm 3 applies a pushing force to the drawer 1 through elastic deformation, so that the drawer 1 does not wobble back and forth. Wherein, when the second elastic pressure arm 3 is squeezed and undergoes elastic deformation, the second through groove 12 is used to provide space for the second elastic pressure arm 3.

[0045] In one embodiment, the left and right sidewalls of the shell 1 are respectively provided with a plurality of first elastic pressure arms 2. Preferably, the plurality of first elastic pressure arms 2 on the left and right sides are symmetrically arranged about the axis of the length direction of the shell 1.

[0046] Multiple first elastic pressure arms 2 are respectively provided on the left and right side walls of the drawer 1. The multiple first elastic pressure arms 2 on the left and right sides are symmetrically arranged about the axis of the length direction of the drawer 1. This symmetrical structure design can make the elastic pressure arms on the left and right sides generate a uniform clamping force on the drawer 1 during installation, ensuring that the drawer 1 can be accurately centered when inserted into the box 4, avoiding displacement or tilting caused by uneven force. For example Figure 1 In the embodiment shown, the left and right side walls of the shell 1 are respectively provided with two first elastic pressure arms 2.

[0047] Specifically, when the shell 1 is inserted into the box 4, the first elastic pressure arms 2 on the left and right sides embed into the limiting grooves on both sides of the box 4 by means of their own elastic deformation. Through the symmetrical distribution structure design, not only can a stable positioning effect be formed during the snap-fit, but the mutual balance of the elastic forces on both sides can also offset the lateral forces that may be generated during the installation process, so that the shell 1 remains in a centered state within the box 4. At the same time, the symmetrical arrangement of multiple first elastic pressure arms 2 can evenly distribute the clamping force, avoid structural damage caused by local stress concentration, and reduce the impact risk to internal components such as the motherboard during installation through the buffering effect of elastic deformation. Compared with the traditional screw fixing method, this symmetrical elastic pressure arm structure can not only achieve efficient positioning and snap-fit, but also improve the convenience of installation and the stability of the structure, and facilitate later maintenance and disassembly.

[0048] In one embodiment, the inner plate surface of the shell 1 is provided with a plurality of second elastic pressure arms 3, which are spaced apart along the length direction of the shell 1.

[0049] In this embodiment, the inner panel of the drawer 1 is provided with multiple second elastic pressure arms 3, which are spaced apart along the length of the drawer 1. This spaced arrangement allows the second elastic pressure arms 3 to provide elastic support and ensure a tight fit between the drawer 1 and the front panel of the drawer 1 when the drawer 1 is inserted into the box 4. Specifically, the spaced second elastic pressure arms 3 can generate a uniform axial thrust during the insertion of the drawer 1 by means of the elastic deformation of each second elastic pressure arm 3, ensuring a seamless abutment between the drawer 1 and the front panel of the drawer 1, and avoiding tilting or gaps caused by single-point force. In addition, the spaced arrangement of multiple second elastic pressure arms 3 can disperse the backward thrust on the drawer 1, avoiding fatigue damage to the pressure arms caused by local stress concentration. Compared with the traditional screw fixing method, this spaced second elastic pressure arm 3 structure significantly improves installation efficiency and structural reliability while ensuring that the drawer 1 is tightly attached to the front panel.

[0050] In one embodiment, the first elastic pressure arm 2 and the second elastic pressure arm 3 are both integrally formed with the shell 1.

[0051] In this embodiment, both the first elastic pressure arm 2 and the second elastic pressure arm 3 are integrally formed with the shell 1. This integrated structural design can significantly improve the connection strength and structural stability between the elastic pressure arm and the shell 1. Specifically, the integral forming process makes the elastic pressure arm and the shell 1 form a seamless integral structure, avoiding stress concentration or connection failure problems that may occur in traditional assembly processes such as welding and riveting, and ensuring that the pressure arm is not easy to detach or break from the shell 1 during long-term elastic deformation.

[0052] In one embodiment, the top of the housing 1 is provided with a wire outlet hole 13, which is suitable for the circuit board wiring to pass through.

[0053] In this embodiment, the cable outlet hole 13 provided on the top of the housing 1 is designed to facilitate the passage of circuit board lines, allowing the circuit board wiring to be led out of the housing 1 through the cable outlet hole 13 to achieve electrical connection with external devices. This cable outlet hole 13 not only meets the wiring requirements of the circuit board lines, but also ensures the overall structural integrity of the housing 1 after it is installed in the box 4, avoiding the risk of installation inconvenience or damage caused by exposed lines, while providing a convenient channel for the layout and connection of the internal circuit of the housing 1.

[0054] Secondly, such as Figure 5 and Figure 6 As shown, this utility model also provides a host, including a housing 5 and a control box, with the control box installed in the housing 5; wherein, the side wall of the housing 5 and the interior of the box 4 together form a receiving cavity for accommodating the shell 1.

[0055] When the main unit's housing 5 is installed and fitted with the control box, the side wall of the housing 5 and the interior of the box 4 together form a receiving cavity for accommodating the pull-out 1. At this time, the side of the box 4 closest to the housing 5 is open. During the process of inserting the pull-out 1 into the receiving cavity, the first elastic pressure arm 2 on the left and right side walls elastically engages with the first slot 41 on the left and right side walls of the box 4 through the first abutting section 22, keeping the pull-out 1 horizontally centered in the receiving cavity; the second elastic pressure arm 3 on the inner plate abuts with the rear side wall of the box 4 through the second abutting section 32, pushing the pull-out 1 forward until it is tightly against the front end face of the housing 5. This structural design, in which the housing 5 and the box 4 together form the receiving cavity, not only achieves screwless fastening of the shell 1 within the receiving cavity through the snap-fit ​​of the pressure arm, avoiding the risk of damage to the internal circuitry caused by screw installation, but also ensures installation accuracy by utilizing the limiting fit between the housing 5 and the box 4, so that the cable outlet 13 of the shell 1 precisely corresponds to the wiring position of the housing 5. At the same time, the compact receiving cavity layout facilitates the internal space planning of the host, greatly improving the installation efficiency and maintenance convenience of the control box within the host.

[0056] In one embodiment, the side wall of the housing includes at least one flat section, and the housing 4 is mounted on the flat section.

[0057] In this embodiment, the flat portion provided on the side wall of the housing provides a stable mounting reference surface for the box 4. When the box 4 is installed at the flat portion, it ensures the fitting accuracy between the box 4 and the side wall of the housing, thereby maintaining a regular spatial structure in the receiving cavity formed by the cavity of the box 4 and the side wall of the housing. When the drawer 1 is inserted into the receiving cavity, the first slots 41 on the left and right side walls of the box 4 are precisely aligned with the first elastic pressure arms 2 on the left and right side walls of the drawer 1, facilitating the first abutting section 22 of the first elastic pressure arm 2 to engage with the first slot 41 for horizontal positioning. At the same time, the second elastic pressure arm 3 on the rear side wall of the box 4 cooperates with the inner plate surface of the drawer 1, making the drawer 1 fit tightly against the front end face of the housing. This installation and cooperation method between the flat portion of the housing side wall and the box 4 utilizes the planar characteristics of the flat portion to ensure the stability of the box 4 installation.

[0058] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0059] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
