Abstract
Description
Technical Field
[0001] This utility model relates to the field of controller technology, and in particular to a controller and controller components. Background Technology
[0002] In next-generation intelligent device control systems, controllers are typically mounted on walls for user operation. Due to varying installation environments—some walls have limited space, while others are unsuitable for drilling—the installation methods for controllers differ depending on the wall surface. However, most current controllers are only compatible with a single installation method, resulting in poor compatibility with different installation environments. Utility Model Content
[0003] In response to the problems pointed out in the background art, some embodiments of this application relate to a controller that can realize three installation methods: controller rail installation, wall-mounted installation, and wall-fixed installation, which can adapt to different installation environments and improve the installation flexibility of the controller.
[0004] To achieve the above-mentioned objectives, the present invention employs the following technical solution:
[0005] Embodiments of this application provide a controller adapted for installation on either a guide rail or a wall, the controller comprising:
[0006] The housing has wall mounting holes and clearance parts on its back to avoid the guide rail;
[0007] The main control board is located inside the housing;
[0008] Multiple connecting portions are installed on the back of the housing and are spaced apart on both sides of the clearance portion along the extending direction of the clearance portion. Each connecting portion is provided with a through portion and can be switched between a first position and a second position.
[0009] When the controller is installed on the guide rail, the ends of multiple connecting parts in the first position and near the clearance part extend into the clearance part to engage with the first and second flanges of the guide rail.
[0010] When the controller is wall-mounted on the wall, the housing is fixed to the wall by a first fastener through the wall-mounting hole; or, while the housing is fixed to the wall by the first fastener through the wall-mounting hole, at least one of the connecting parts is in a second position and fixed to the wall by a second fastener passing through the through part.
[0011] When the controller is fixedly installed on the wall, at least one connecting part on one side of the clearance part and at least one connecting part on the other side of the clearance part are both in the second position and are fixed to the wall by a third fastener passing through the corresponding through part.
[0012] The embodiments involved in this application have the following advantages and beneficial effects:
[0013] With the switchable connection part, when the controller is installed on the guide rail, the first connection part is in the first position, and the connection part engages with the first and second flanges of the guide rail. When the controller is wall-mounted, the connection part is switched to the second position to release the guide rail, and the housing is fixed to the wall on the first fastener through the wall mounting hole. The second fastener, which passes through at least one connection part, is fixed to the wall. At this time, the unused remaining connection part can be in the first position. When the controller is fixedly installed on the wall, the connection part is also switched to the second position to release the guide rail, and the controller is fixed to the wall on the third fastener, which passes through at least one connection part on one side of the clearance part and at least one connection part on the other side. At this time, the unused remaining connection part can be in the first position. In this way, three installation methods can be realized: guide rail installation, wall mounting, and fixed installation, which improves the flexibility of controller installation scenarios.
[0014] In some embodiments of this application, the controller further includes:
[0015] Multiple guide portions, each corresponding to a multiple connecting portion and disposed on the back of the housing, extend in a direction perpendicular to the extending direction of the avoidance portion, with one end of the guide portion away from the avoidance portion communicating with the outside and the other end of the guide portion close to the avoidance portion communicating with the avoidance portion.
[0016] When the connecting part slides in the guide part along the first direction, the connecting part switches from the first position to the second position; when the connecting part slides in the guide part along the second direction, the connecting part switches from the second position to the first position.
[0017] The embodiments involved in this application have the following advantages and beneficial effects:
[0018] By setting multiple guide parts, multiple connecting parts can be slidably matched, and the connecting parts can be easily switched between the first and second positions by using a sliding switching method.
[0019] In some embodiments of this application, the sidewall of the guide portion is formed with:
[0020] The first snap-fit portion penetrates the side wall of the guide portion in which it is located;
[0021] The second latching part penetrates the side wall of the guide part in which it is located, and the first latching part is closer to the avoidance part than the second latching part;
[0022] When the connecting part is in the first position, the latching protrusion on the connecting part engages with the first latching part; when the connecting part is switched from the first position to the second position, the latching protrusion disengages from the engagement with the first latching part and engages with the second latching part.
[0023] When the connecting portion is in the second position, the connecting portion extends beyond the corresponding edge of the housing to expose the through portion.
[0024] The embodiments involved in this application have the following advantages and beneficial effects:
[0025] A latching protrusion is provided on the connecting part, and a first latching part and a second latching part are provided on the side wall of the guide part. The connecting part is positioned in a first position by the cooperation of the latching protrusion and the first latching part, and in a second position by the cooperation of the latching protrusion and the second latching part. The switching of the connecting part between the first and second positions is achieved by the latching method, which is convenient to operate and stable after latching.
[0026] In some embodiments of this application, there are two first snap-fit portions, and the two first snap-fit portions are arranged opposite to each other along the extension direction of the avoidance portion;
[0027] The number of the second snap-fit portion is two, and the two second snap-fit portions are arranged opposite each other along the extension direction of the avoidance portion;
[0028] The number of protrusions on the connecting part is also two, and the two protrusions are arranged opposite each other along the extension direction of the avoidance part.
[0029] The embodiments involved in this application have the following advantages and beneficial effects:
[0030] Two first locking parts, two second locking parts, and two locking protrusions are respectively arranged in a relatively opposite manner to facilitate even force distribution when the connection part is switched. During the switching, the two locking protrusions and two locking parts need to be locked in correspondingly to complete the switching, ensuring switching reliability and improving the stability of the controller installation.
[0031] In some embodiments of this application, the connecting portion has:
[0032] The first cantilever extends along the sliding direction of the connecting part, and the locking protrusion is provided at the free end of the first cantilever.
[0033] The embodiments involved in this application have the following advantages and beneficial effects:
[0034] The locking protrusion is formed by a cantilever. One end of the first cantilever is connected to the connecting part as a fixed end, and the suspended end is a free end. This allows the free end of the first cantilever to bend and deform under external force. When the connecting part changes position, it applies pressure to the locking protrusion and deforms. When it is locked into the locking part, it recovers its deformation, which facilitates locking.
[0035] In some embodiments of this application, the protrusion near the avoidance portion has a rounded corner;
[0036] A first chamfer is formed on the upper sidewall of the first snap-fit portion near the second snap-fit portion, which mates with the rounded corner. The first chamfer is inclined from the upper sidewall toward the second snap-fit portion.
[0037] A second chamfer is formed on the lower sidewall of the second snap-fit portion near the first snap-fit portion, which cooperates with the rounded corner. The second chamfer is inclined from the lower sidewall toward the first snap-fit portion.
[0038] The embodiments involved in this application have the following advantages and beneficial effects:
[0039] When the connecting part switches from the first position to the second position, the locking part deforms by relying on the first chamfer to switch to the second locking part. When the connecting part switches from the second position to the first position, the rounded corner and the second chamfer work together to generate a gradually increasing pressure on the locking part, making it easy to deform and achieving a labor-saving switching.
[0040] In some embodiments of this application, one of the sidewalls of the guide portion and the sidewall of the connecting portion is provided with a first limiting portion and the other is provided with a second limiting portion. When the connecting portion slides within the guide portion, the first limiting portion and the second limiting portion slide in cooperation.
[0041] The embodiments involved in this application have the following advantages and beneficial effects:
[0042] When the connecting part slides from the first position to the second position, the locking part deforms by relying on the first chamfer. At this time, a large external force is required. By setting the first and second limiting parts for limiting cooperation, the connecting part is prevented from coming off when it slides from the first position to the second position, ensuring that the connecting part can switch positions stably and improving the reliable installation of the controller.
[0043] In some embodiments of this application, the first limiting portion is formed in the travel groove of the guide portion, and the travel groove extends along the first direction;
[0044] The connecting part is provided with a second cantilever, the length of the second cantilever extends along the sliding direction of the connecting part, and a second limiting part is provided at the free end of the second cantilever.
[0045] The embodiments involved in this application have the following advantages and beneficial effects:
[0046] The second limiting part is formed by a cantilever. One end of the second cantilever is connected to the connecting part as a fixed end, and the suspended end is a free end. When the connecting part slides along the guide part, the free end of the second cantilever can bend and deform under the action of external force. This allows the second limiting part to slide and guide in the stroke groove while relying on the deformation force to stick tightly to the bottom wall of the stroke groove, ensuring that the second limiting part is reliably located in the stroke groove, thus achieving reliable guidance and limiting.
[0047] In some embodiments of this application, the wall-mounting hole is located on the first side of the clearance portion and extends from the side wall of the clearance portion near the first side toward the first side, and the wall-mounting hole communicates with the clearance portion.
[0048] The embodiments involved in this application have the following advantages and beneficial effects:
[0049] By setting a wall-mounting hole, at least one connecting part can be used to achieve stable wall mounting. The wall-mounting hole is connected to the clearance part, which makes it convenient to insert the first fastener into the wall-mounting hole through the clearance part.
[0050] Some embodiments of this application also relate to a controller component, including:
[0051] A guide rail having a first flange and a second flange along the length of the guide rail;
[0052] Controller, the controller includes:
[0053] The housing has a clearance portion on its back to avoid the guide rail;
[0054] The main control board is located inside the housing;
[0055] Multiple connecting portions are installed on the back of the housing and are spaced apart on both sides of the clearance portion along the extending direction of the clearance portion. Each connecting portion is provided with a through portion and can be switched between a first position and a second position.
[0056] When the controller is installed on the guide rail, the ends of multiple connecting parts in the first position and near the clearance part extend into the clearance part to engage with the first and second flanges of the guide rail.
[0057] When the multiple connecting parts are in the second position, the ends of the multiple connecting parts that extend into the clearance part move away from the clearance part to release the guide rail;
[0058] When the connecting part is in the first position, the through portion of the connecting part is at least partially covered by the housing. When the connecting part is in the second position, the through portion of the connecting part extends outside the housing to expose the through portion. The controller can be fixed by fasteners passing through the through portion.
[0059] The embodiments involved in this application have the following advantages and beneficial effects:
[0060] When all the connecting parts are in the first position, they respectively engage with the guide rail, enabling the controller and guide rail to be installed together. When all the connecting parts are in the second position, the guide rail is released, allowing the controller to be used independently without the guide rail.
[0061] When the controller is used independently, it can be installed independently through the through part of the connector in the second position and the fastener.
[0062] Furthermore, the controller can be detached from the guide rail, making it convenient to replace either the controller or the guide rail.

[0093] The distribution boxes of new-generation smart devices (such as smart building equipment) are often equipped with controllers. These controllers can be used to control smart building equipment (such as air conditioners and elevators). However, due to limitations in installation space and environment, the controllers need to be installed flexibly.
[0094] In some embodiments of this application, the controller can be a DDC controller (Direct Digital Controller) or a PLC controller (Programmable Logic Controller). The controller can be used to control systems and equipment such as air conditioning systems, hot water systems, fresh air systems, lighting systems, and elevator systems.
[0095] See Figures 1 to 18 In some embodiments of this application, a controller 1000 is proposed, which includes a housing 100 and a main control board (not shown).
[0096] The housing 100 forms the appearance of the controller 1000, and the interior of the housing 100 forms a receiving space, in which the main control board is disposed.
[0097] In some embodiments of this application, the housing 100 may include an upper housing 110, a lower housing 120 and a maintenance cover 130. The upper housing 110 and the lower housing 120 are connected and enclose the receiving space. A maintenance opening 111A is provided on the front side 111 of the upper housing 110. The maintenance cover 130 is detachably installed on the upper housing 110 and covers / exposes the maintenance opening 111A.
[0098] During maintenance, the maintenance personnel can remove the maintenance cover 130 and perform maintenance or repair operations on the electrical components in the containment space through the maintenance port 111A, such as resetting, copying data, or performing other repairs.
[0099] In some embodiments of this application, for the convenience of wall mounting and rail mounting of the controller 1000, see [link to relevant documentation]. Figure 2 and Figure 3 The back of the housing 100 is provided with wall mounting holes 123 / 123A and a clearance part 121 for the guide rail 2000, and the guide rail 2000 is accommodated in the clearance part 121.
[0100] When housing 100 includes upper housing 110 and lower housing 120, the back side of housing 100 refers to the back side of lower housing 120.
[0101] It should be noted that after the controller 1000 is installed, the surface facing the user is the front 111 of the housing 100, and the opposite side of the front 111 is the back of the housing 100.
[0102] In some embodiments of this application, the controller 1000 further includes a plurality of connecting parts 200 / 200A / 200B, which are also respectively mounted on the back of the housing 100 and can be switched between a first position and a second position.
[0103] The connecting parts 200 / 200A / 200B have the same structure, and the mechanism of the connecting part 200 will be used as an example for explanation.
[0104] See Figure 3 The connecting portion 200 is provided with a through portion 220 (e.g., a mounting hole), and when the connecting portion 200 is in the first position, the through portion 220 is at least partially covered by the housing 100 (see...). Figure 6 That is, the through portion 220 is not fully exposed, and in this case, the through portion 220 cannot be used; when the connecting portion 200 is in the second position (see... Figure 10 and Figure 12 When the through portion 220 extends beyond the housing 100 to fully expose the through portion 220, the through portion 220 can be used.
[0105] In some embodiments of this application, the multiple connecting portions are divided into two parts: a first part and a second part, each part including at least one connecting portion.
[0106] The first part and the second part are located on both sides of the avoidance part 121, respectively. Note that the first part is located on the first side of the avoidance part 121 and the second part is located on the second side of the avoidance part 121.
[0107] When the first part includes multiple connecting parts, the multiple connecting parts in the first part are arranged at intervals on the first side of the clearance part 121. When the second part includes multiple connecting parts, the multiple connecting parts in the second part are arranged at intervals on the second side of the clearance part 121.
[0108] When each of the first and second parts includes only one connecting part, the connecting parts of the first part and the connecting parts of the second part are arranged facing each other relative to the clearance part 121 to ensure the installation stability of the controller 1000 when it is fixedly installed using the connecting parts.
[0109] When one part has one connecting part and the other part has multiple connecting parts in the first and second parts, all connecting parts are arranged in a triangular pattern to ensure the stability of the controller 1000 when it is fixedly installed using connecting parts.
[0110] See Figure 1 and Figure 2 In some embodiments of this application, the first side of the avoidance portion 121 has two connecting portions 200 and 200A, and the second side of the avoidance portion 121 has a connecting portion 200B, and the three connecting portions 200 / 200A / 200B form a triangular arrangement.
[0111] In some embodiments of this application, the controller 1000 may be mounted on either the guide rail 2000 or the wall.
[0112] It should be noted that the wall can be a vertical wall or an inclined wall. The guide rail 2000 can be pasted onto the wall or fixed to the wall with threaded parts.
[0113] In some embodiments of this application, for ease of description, the avoidance portion 121 is along... Figure 3 The solid arrow shown indicates the length extension direction of the avoidance part 121, denoted as left and right extension. The first side of the avoidance part 121 is the upper side and the second side of the avoidance part 121 is the lower side.
[0114] See Figure 7 The clearance portion 121 has a bottom wall 1211, an upper side wall 1212 that abuts the first edge of the bottom wall 1211, and a lower side wall 1213 that abuts the second edge of the bottom wall 1211.
[0115] See back Figure 4 The corresponding guide rail 2000 has a middle U-shaped part 2100 and a first flange 2200 and a second flange (not shown) located on both sides of the middle U-shaped part 2100. Both the first flange 2200 and the second flange extend away from the middle U-shaped part 2100.
[0116] See Figure 2 and Figure 4 In some embodiments of this application, when the connecting portion 200 is installed on the back of the housing 100, the end of the connecting portion 200 near the avoidance portion 121 forms an engaging portion 210, and the end away from the avoidance portion 121 forms a through portion 220.
[0117] In some embodiments of this application, the connecting portion 200 can switch between a first position and a second position. Let the sliding direction of the connecting portion 200 when switching from the first position to the second position be the first direction. Figure 3 (As shown by the dotted-dash arrow), when switching from the second position to the first position, the sliding direction of the connecting part 200 is the second direction. Figure 3 (The dashed arrow shown in the image).
[0118] See Figure 4 When the connecting part 200 is in the first position, the engaging part 210 extends into the avoidance part 121, and the engaging part 210 of the connecting part 200 engages with the first flange 2200 of the guide rail 2000.
[0119] Similarly, for the lower connecting portion, the corresponding engaging portion engages with the second flange of the guide rail 2000. At this time, the through portion 220 is at least partially covered by the housing 100, that is, the through portion 220 is not completely exposed. See [reference needed]. Figure 3 and Figure 6 .
[0120] In some embodiments of this application, when the engaging portion 210 extends into the abutment portion 121, a first gap (not marked) is formed between the engaging portion 210 of the connecting portion 200, the bottom wall 1211 of the abutment portion 121 and its upper side wall 1212, for engaging the first flange 2200 of the guide rail 2000.
[0121] Similarly, a second gap is formed between the engaging part of the lower connecting part, the bottom wall 1211 of the clearance part 121, and its lower side wall 1213, for engaging the second flange of the guide rail 2000, thereby enabling the controller 1000 to be installed on the guide rail 2000 (installation details attached). Figure 2 ).
[0122] When the controller 1000 is installed on the guide rail 2000, the through portions 220 of the connecting portions 200 / 200A / 200B are not fully exposed, that is, see Figure 6 The connection parts 200 / 200A / 200B are not fully visible from the front 111 of the housing 100, thus ensuring the appearance of the controller 1000.
[0123] When the connecting portions 200 / 200A / 200B switch from the first position to the second position, the engaging portion 210 moves away from the clearance portion 121 in the first direction. The engaging portion 210 of the upper connecting portion 200 / 200A releases the first flange 2200 of the guide rail 2000, and the engaging portion of the lower connecting portion 200B releases the second flange of the guide rail 2000. The guide rail 2000 can be removed from the clearance portion 121. At this time, the through portion 220 extends beyond the housing 100 to expose the through portion 220, that is, the through portion 220 can be fully seen from the front 111 of the housing 100 (see...). Figure 10 and Figure 12 ).
[0124] In some embodiments of this application, the controller 1000 can be fixedly mounted to the wall when the guide rail 2000 is removed from the clearance part 121.
[0125] As described above, after the guide rail 2000 can be removed from the clearance portion 121 when all connecting portions 200 / 200A / 200B are in the second position, at least one upper connecting portion of the upper connecting portions 200 / 200A and at least one lower connecting portion of the lower connecting portions 200B can be kept in the second position. In this way, multiple third fasteners are used to pass through the through portions 220 of at least one upper connecting portion and the through portions 220 of at least one lower connecting portion respectively, and are fixed to the wall. The unused remaining connecting portions can be switched from the second position to the first position to ensure the appearance of the controller 1000, or, for the sake of simplifying operation, the unused remaining connecting portions can be kept in the second position.
[0126] The third fastener can be a screw or a nail without threads.
[0127] In some embodiments of this application, when the controller 1000 is fixedly installed, an upper connecting part can be selected and a lower connecting part directly opposite the upper connecting part can be used to ensure stable installation of the controller 1000 with a small number of fasteners.
[0128] In some embodiments of this application, when fixing the controller 1000, one upper connecting part and two lower connecting parts can be used, which form a triangle to ensure the triangular stable installation of the controller 1000.
[0129] In some embodiments of this application, see Figure 3 A wall mounting hole 123 / 123A is also provided on the back of the housing 100. The wall mounting hole 123 / 123A is located on the same side of the clearance portion 121 (for example, on the first side of the clearance portion 121) and is used to hang on the first fastener.
[0130] In some embodiments of this application, when the guide rail 2000 is removed from the clearance part 121, the controller 1000 can be wall-mounted through the wall-mounting hole 123 / 123A or wall-mounted by means of the through part 220 of the connecting part 200 / 200A / 200B.
[0131] In some embodiments of this application, the wall mounting hole 123 / 123A can be a closed hole or an open hole on the lower side.
[0132] In some embodiments of this application, for ease of mounting, the wall mounting hole 123 / 123A is configured as an open hole on the bottom, see [reference]. Figure 3 The wall mounting hole 123 / 123A extends upward from the upper side wall 1212 of the clearance part 121. The wall mounting hole 123 / 123A communicates with the clearance part 121. When the controller 1000 is mounted, the first fastener is more easily inserted into the wall mounting hole 123 / 123A through the lower part that communicates with the clearance part 121.
[0133] In some embodiments of this application, there are two wall-mounting holes 123 / 123A, and the two wall-mounting holes 123 / 123A are arranged at intervals along the left and right extension direction of the clearance portion 121.
[0134] In some embodiments of this application, after the guide rail 2000 can be removed from the clearance part 121 when all connecting parts 200 / 200A / 200B are in the second position, all connecting parts 200 / 200A / 200B can be switched to the first position, so that the first fastener fixed to the wall can be hung through the wall mounting hole 123 / 123A.
[0135] In the above embodiment, the controller 1000 is suspended on the first fastener by the cooperation of the two wall mounting holes 123 / 123A, which can prevent the controller 1000 from swaying left and right, thereby stably suspending the controller 1000 on the wall.
[0136] In some embodiments of this application, after the guide rail 2000 can be removed from the clearance part 121 when all connecting parts 200 / 200A / 200B are in the second position, at least one connecting part (e.g., connecting part 200A) can be selected to be in the second position and the remaining connecting parts can be switched to the first position. In this way, the controller 1000 is fixed to the wall by the first fastener that is hung on the wall through the wall hole 123 / 123A, and at the same time, at least one second fastener is used to pass through the through part of the selected at least one connecting part 200A respectively. The controller 1000 is fixed to the wall by a combination of suspension and fixing.
[0137] The selected connector 200A and the two wall mounting holes 123 / 123A form a triangle to achieve stable fixing of the controller 1000.
[0138] As mentioned above, the two connecting parts can be selected from the two lower connecting parts (not shown) located in the lower connecting part, thereby avoiding the controller 1000 from shaking around.
[0139] In some embodiments of this application, the number of wall mounting holes 123 / 123A and connecting parts 200 / 200A / 200B can be flexibly set to adapt to different installation environments. For example, there may be one wall mounting hole 123 / 123A and two connecting parts 200 / 200A / 200B (one upper connecting part 200 / 200A and one lower connecting part 200B).
[0140] In some embodiments of this application, in order to achieve the switching between the first and second positions of the connecting parts 200 / 200A / 200B, see [link to relevant documentation]. Figure 7 The controller 1000 also includes a plurality of guide portions 122 / 122A / 122B, the number of which is consistent with the number of the plurality of connecting portions 200 / 200A / 200B. That is, a connecting portion 200 / 200A / 200B slides within a guide portion 122 / 122A / 122B to realize switching from a first position to a second position along a first direction, and switching from a second position to a first position along a second direction.
[0141] See Figure 7 Multiple guide portions 122 / 122A / 122B are also provided on the back of the housing 100, specifically on the back of the lower housing 120. The extension direction of the guide portions 122 / 122A / 122B is perpendicular to the extension direction of the clearance portion 121, that is, the extension direction of the guide portions 122 / 122A / 122B is the up and down direction.
[0142] The guide portion 122 / 122A / 122B extends vertically and communicates with the clearance portion 121, so that when the connecting portion 200 / 200A / 200B slides through the guide portion 122 / 122A / 122B, the engaging portion 210 can extend near the clearance portion 121 or retract away from the clearance portion 121 through the open lower part of the guide portion 122 / 122A / 122B.
[0143] In some embodiments of this application, the structure of guide portion 122 / 122A / 122B is also the same. The structure of guide portion 122 will be described as an example below.
[0144] In some embodiments of this application, see Figure 8 A first snap-fit portion 1223 / 1223A and a second snap-fit portion 1224 / 1224A are formed on the side wall of the guide portion 122. Both the first snap-fit portion 1223 / 1223A and the second snap-fit portion 1224 / 1224A penetrate through the side wall where they are located, that is, both the first snap-fit portion 1223 / 1223A and the second snap-fit portion 1224 / 1224A are snap-fit grooves.
[0145] In some embodiments of this application, corresponding to the first latching portion 1223 / 1223A and the second latching portion 1224 / 1224A, see [link to relevant documentation]. Figure 9 A latching protrusion 241 is provided on the connecting part 200. The latching protrusion 241 switches between latching the first latching part 1223 / 1223A and the second latching part 1224 / 1224A to switch the connecting part 200 to the first position and the second position.
[0146] In some embodiments of this application, see Figure 7 and Figure 8 The first locking portion 1223 / 1223A is closer to the avoidance portion 121 than the second locking portion 1224 / 1224A. Therefore, when the connecting portion 200 is in the first position, the locking protrusion 241 engages with the first locking portion 1223 / 1223A.
[0147] When the connecting part 200 switches to the second position along the first direction, the latching protrusion 241 disengages from the first latching part 1223 / 1223A and engages with the second latching part 1224 / 1224A. When the connecting part 200 switches back to the first position along the second direction, the latching protrusion 241 disengages from the second latching part 1224 / 1224A and engages with the first latching part 1223 / 1223A.
[0148] In some embodiments of this application, to ensure the stability of the connecting portion 200 sliding within the guide portion 122, the number of first engaging portions 1223 / 1223A, the number of second engaging portions 1224 / 1224A, and the number of engaging protrusions 241 are all two. See [reference needed] Figure 8 and Figure 9 .
[0149] The two first engaging portions 1223 / 1223A are arranged opposite each other along the extension direction of the avoidance portion 121, see [reference]. Figure 8 .
[0150] In some embodiments of this application, the back of the guide portion 122 has a vertically penetrating opening that extends through the inside of the guide portion, so that the back of the guide portion 122 forms a first back sidewall 1221 and a second back sidewall 1221A on the left and right sides.
[0151] Two first latching portions 1223 / 1223A are arranged opposite to each other on the first back sidewall 1221 and the second back sidewall 1221A, and two second latching portions 1224 / 1224A are arranged opposite to each other on the first back sidewall 1221 and the second back sidewall 1221A, with the two first latching portions 1223 / 1223A being closer to the avoidance portion 121 than the two second latching portions 1224 / 1224A.
[0152] Correspondingly, see Figure 9 The connecting part 200 is also provided with two oppositely arranged latching parts 241 corresponding to the two first latching parts 1223 / 1223A (or the two second latching parts 1224 / 1224A), referred to as: first latching part (unmarked) and second latching part (unmarked).
[0153] The first latching protrusion switches to engage with the first latching part 1223 and the second latching part 1224 on the left side, and the second latching protrusion switches to engage with the first latching part 1223A and the second latching part 1224A on the right side.
[0154] The two first latching parts 1223 / 1223A, the two second latching parts 1224 / 1224A, and the two latching protrusions 241 arranged opposite to each other facilitate even force distribution when the connecting part 200 switches positions. During switching, the two latching protrusions 241 and the two latching parts need to be latched in corresponding positions to complete the switching, ensuring switching reliability and improving the stability of the controller 1000 installation.
[0155] In some embodiments of this application, in order to facilitate the position switching of the connecting part 200, a structure of a protruding part 241, a first locking part 1223 / 1223A, and a second locking part 1224 / 1224A are designed.
[0156] See Figure 9 and Figure 11 The protrusion 241 is cylindrical, and a rounded corner 2411 is formed on the side near the relief part 121.
[0157] See Figure 5 and Figure 11 A first chamfer 1225 is formed on the side wall (i.e., the upper side wall) of the first snap-fit portion 1223A near the second snap-fit portion 1224A, which cooperates with the rounded corner 2411. The first chamfer 1225 is inclined from the upper side wall toward the second snap-fit portion 1224A.
[0158] A second chamfer 1226 is formed on the side wall (i.e., the lower side wall) of the second snap-fit portion 1224A near the first snap-fit portion 1223A, which cooperates with the rounded corner 2411. The second chamfer 1226 is inclined from the lower side wall toward the first snap-fit portion 1223A.
[0159] In some embodiments of this application, see Figure 5 When the connecting part 200 is in the first position, that is, when the latching protrusion 241 engages with the first latching part 1223A, if the connecting part 200 switches from the first position to the second position (that is, from the first position to the second position), Figure 5 Switch to Figure 11 When the connecting part 200 needs to slide along the first direction, the locking part 241 can easily deform by relying on the first chamfer 1225, thereby sliding to cooperate with the second locking part 1224A.
[0160] When the connecting part 200 switches from the second position to the first position (that is, from the second position to the first position) Figure 11 Switch to Figure 5 When the connecting part 200 needs to slide along the second direction, the rounded corner 2411 and the second chamfer 1226 of the latching part 241 work together to generate a gradually increasing pressure on the latching part 241 so that it is easy to deform and achieve a labor-saving sliding switch to the first position.
[0161] In some embodiments of this application, the protrusion 241 is formed in a cantilever form, which makes it easy to deform.
[0162] See Figure 9 The connecting part 200 has a first cantilever 240 and a first through hole 242 that provides deformation space for the first cantilever 240. The length extension direction of the first cantilever 240 is along the sliding direction of the connecting part 200. The end of the first cantilever 240 that is connected to the connecting part 200 is a fixed part, and the suspended end is a free end. The latching part 241 is provided on the free end of the first cantilever 240.
[0163] Correspondingly, a first locking protrusion and a second locking protrusion are provided, and two first cantilever 240s are also provided.
[0164] In some embodiments of this application, a limiting structure is provided in order to better guide the connecting portion 200 to slide within the guide portion 122 and prevent it from easily dislodging from the guide portion 122.
[0165] The limiting structure includes a first limiting part and a second limiting part that cooperates with the first limiting part.
[0166] In some embodiments of this application, one of the sidewalls of the guide portion 122 and the sidewall of the connecting portion 200 is provided with a first limiting portion and the other is provided with a second limiting portion. When the connecting portion 200 slides within the guide portion 122, the first limiting portion and the second limiting portion slide in cooperation.
[0167] In some embodiments of this application, in order to balance the sliding of the connecting part 200, two first limiting parts and two second limiting parts are also provided.
[0168] In some embodiments of this application, the first limiting portion is a travel groove formed on the side wall of the guide portion 122, see [link to relevant documentation]. Figure 8 A travel groove 1222 is formed on the first back sidewall 1221 of the guide portion 122, and a travel groove 1222A is formed on the second back sidewall 1221A of the guide portion 122. Figure 11 As shown in the diagram, the extension direction of the travel groove 1222 / 1222A is consistent with the sliding direction of the connecting part 200.
[0169] In some embodiments of this application, the second limiting part is a limiting slider 231 formed on the second cantilever 230.
[0170] Among them, see Figure 9 The connecting part 200 has a second cantilever 230 and a second through hole 232 that provides deformation space for the second cantilever 230. The length extension direction of the first cantilever 240 is along the sliding direction of the connecting part 200. The end of the second cantilever 230 that is connected to the connecting part 200 is a fixed part, and the suspended end is a free end. The limiting slider 231 is provided on the free end of the second cantilever 230.
[0171] Two stroke slots 1222 / 1222A are set accordingly, and two limit sliders 231 are also set accordingly.
[0172] The cantilevered design of the limiting slider 231 not only serves as a guide, but also allows the bottom wall of the stroke groove 1222A to deform the limiting slider 231 when it contacts the bottom wall. This causes the limiting slider 231 to reapply its restoring force to the bottom wall of the stroke groove 1222A, ensuring that the two can reliably slide together.
[0173] When the connecting part 200 slides along the first direction, and the limiting slider 231 slides along the stroke groove 1222A in the first direction and the connecting part 200 slides into place to switch to the second position, the upper edge of the limiting slider 231 is in close contact with the upper side wall of the stroke groove 1222A (see...). Figure 11 This serves to limit the connection part 200 and prevent it from coming out of the guide part 122.
[0174] When the connecting part 200 slides along the second direction, and the limiting slider 231 slides along the stroke groove 1222A in the second direction and the connecting part 200 slides into place to switch to the first position, the lower edge of the limiting slider 231 is in close contact with the lower side wall of the stroke groove 1222A (see...). Figure 5 This serves to limit the connection part 200 and prevent it from sliding further downward.
[0175] In some embodiments of this application, a controller assembly is also provided, which includes a controller 1000 and a guide rail 2000.
[0176] The controller assembly allows the controller 1000 to be mounted on the guide rail 2000, enabling the controller 1000 to slide and adjust its position on the guide rail 2000. Alternatively, if the guide rail 2000 is damaged or the installation space is insufficient, the guide rail 2000 can be released and the controller 1000 can be installed separately, improving the convenience and flexibility of the controller 1000 installation.
[0177] The controller 1000 includes a housing 100, a main control board, and multiple connecting parts 200 / 200A / 200B, wherein a clearance part 121 for a clearance guide rail 2000 is provided on the back.
[0178] The structure of the connecting parts 200 / 200A / 200B and the snap-fit between the connecting parts 200 / 200A / 200B and the guide rail 2000 are as described above, and will not be repeated here.
[0179] Furthermore, after the guide rail 2000 is released from the connecting part 200 / 200A / 200B, the fastener controller 1000 can be fixed via the through part 220 passing through the connecting part 200 / 200A / 200B in the second position.
[0180] In some embodiments of this application, wall mounting holes 123 / 123A can also be provided on the back of the housing 100. The method of fixing the controller 1000 is the same as the wall mounting method described above, and will not be repeated here.
[0181] In some embodiments of this application, as described above, see [link to relevant documentation]. Figure 13When a maintenance port 111A is provided on the front side 111 of the upper housing 110, and a removable maintenance cover 130 is provided to facilitate the maintenance of the controller 1000, the maintenance cover 130 can be detachably installed on the front side 111 of the upper housing 110.
[0182] Furthermore, since the maintenance cover 130 needs to be repeatedly disassembled and reassembled, the fixing of the maintenance cover 130 needs to meet the requirements of being both securely fixed and easy to disassemble and reassemble.
[0183] In some embodiments of this application, see Figure 13 The front side 111 of the housing 100 is also provided with a receiving portion 111B / 111C and a locking portion 111D / 111E. The receiving portion 111B / 111C and the locking portion 111D / 111E are both formed on the front side 111 of the upper housing 110 and communicate with the receiving space of the housing 100.
[0184] In some embodiments of this application, a first hook portion is formed within the receiving portion, for example, see [link to relevant documentation]. Figure 17 A first hook portion 111B1 is formed within the receiving portion 111B to cooperate with the maintenance cover 130 to achieve the maintenance cover 130 in the installation direction (see...). Figure 13 and Figure 15 (The direction indicated by the middle arrow) is fixed at the front end.
[0185] In some embodiments of this application, the length extension direction of the mounting portion 111D / 111E is along the installation direction of the maintenance cover 130.
[0186] In some embodiments of this application, taking the card unit 111D as an example, see... Figure 17 The locking part 111D includes an insertion part 111D1 and a limiting part 111D2 that are connected to each other. The opening width W1 of the insertion part 111D1 in the direction perpendicular to the installation direction is greater than the opening width W2 of the limiting part 111D2 in the direction perpendicular to the installation direction. In this way, by arranging the different opening sizes, the locking part of the maintenance cover 130 is used to fix the rear end of the maintenance cover 130 in the installation direction to prevent it from tilting.
[0187] In some embodiments of this application, the maintenance cover 130 also includes a mounting portion.
[0188] When the maintenance cover 130 is installed, the hook part is inserted through the insertion part 111D1 and when the maintenance cover 130 is installed in place, the hook part is engaged with the inner wall of the limiting part 111D2 to prevent the maintenance cover 130 from tilting off the front, thus achieving the purpose of preventing the rear end of the maintenance cover 130 from tilting.
[0189] In some embodiments of this application, the mounting portion may be a slider formed on the back of the maintenance cover 130 that can be mounted, such as an L-shaped slider.
[0190] When installed in place, the second hook portion 133 / 134 of the maintenance cover 130 inserts into the receiving portion 111B / 111C and hooks onto the corresponding first hook portion (see...). Figure 19 This allows the front end of the maintenance cover 130 to be fixed. At the same time, since the hook part is hooked onto the inner wall of the limiting part 111D2, the rear end of the maintenance cover 130 will be tightly fastened to the front 111 of the upper housing 110 when the hook part does not detach from the limiting part 111D2. Therefore, the rear end of the maintenance cover 130 will not lift up.
[0191] At this time, the maintenance cover 130 is stably installed on the front 111 of the upper housing 110 and covers the maintenance port 111A.
[0192] When disassembling the maintenance cover 130, push the maintenance cover 130 forcefully in the disassembly direction (i.e., the opposite direction to the installation direction) to disengage the first hook part 111B1 and the second hook part 133. After the hook part exits through the insertion part 111D1, rotate the maintenance cover 130 to complete the disassembly of the maintenance cover 130.
[0193] It should be noted that in order to ensure that the maintenance cover 130 is securely installed, a considerable amount of force is required to push the maintenance cover 130 when it is removed. Therefore, textures (not shown) for increasing friction between fingers can be designed on the front of the maintenance cover 130.
[0194] In some embodiments of this application, to ensure the stability of the maintenance cover 130 when installed on the housing 100 and the ease of disassembly, see [reference needed]. Figures 16 to 19 The first hook portion 111B1 is provided on the inner side wall of the receiving portion 111B facing the front side 111 of the housing 100.
[0195] See Figure 16 The first hook portion 111B1 has an inclined first side surface 111B3 and a second side surface 111B2. The free ends of the first side surface 111B3 and the free ends of the second side surface 111B2 are close together due to the inclination, so that the first hook portion 111B1 forms a wedge-shaped portion.
[0196] Correspondingly, see Figure 19 The second hook portion 133 has an inner side that matches the second side 111B2. That is, the inner side is inclined in the same direction as the second side 111B2. This kind of matching inclined side ensures that the two are stably assembled.
[0197] When the maintenance cover 130 is installed, the inclined first side 111B3 can guide the second hook part 133 to pass under the first hook part 111B1 and hook onto the second side 111B2.
[0198] The inclined second side 111B2 not only increases the hooking area with the second hook 133 after the maintenance cover 130 is installed, but also the inclined guide facilitates the separation of the first hook 111B1 and the second hook 133 when force is applied in the disassembly direction.
[0199] In some embodiments of this application, see Figure 13 and Figure 14 The maintenance cover 130 also includes a guide rib 135 formed on the back of the maintenance cover 130 and extending away from the back of the maintenance cover 130.
[0200] The connecting part is formed on the guide rib plate 135, see Figure 13 and Figure 14 A protrusion 136 is provided on one side of the guide rib plate 135. The protrusion 136 is arranged on the side wall of the guide rib plate 135 to form the hook part as described above.
[0201] In some embodiments of this application, other forms of bumps 136 may also be provided, such as semicircles.
[0202] Correspondingly, to accommodate guide rib 135, see Figure 17 The locking part 111D also includes an extension part 111D3, which is connected to the insertion part 111D1 and the limiting part 111D2 respectively, and the limiting part 111D2 is located between the extension part 111D3 and the insertion part 111D1.
[0203] During the sliding installation of the maintenance cover 130, the guide rib plate 135 slides within the locking part 111D, and at the same time, the protrusion 136 can be hooked onto the inner wall of the limiting part 111D2.
[0204] In some embodiments of this application, to ensure the stable installation and removal of the maintenance cover 130, see [reference needed]. Figure 17 The number of receiving parts 111B / 111C, the number of first hook parts 111B1, the number of second hook parts 133 / 134, the number of locking parts 111D / 111E, and the number of hanging parts are all two, and they are arranged opposite each other in a direction perpendicular to the detachable direction of the maintenance cover 130, so as to facilitate even force distribution and reliable disassembly and assembly when disassembling and assembling the maintenance cover 130.
[0205] In some embodiments of this application, see Figure 13 The maintenance cover 130 includes a front panel 131 and a side panel 132 that abuts against the front panel 131.
[0206] Since many electrical components are placed in the housing 100, heat dissipation holes need to be opened on the housing 100 to ensure that each electrical component dissipates heat when it is working.
[0207] See Figure 13 A number of first heat dissipation holes 112 are opened on the side wall of the upper housing 110, and a number of second heat dissipation holes are also opened on the side panel 132 of the maintenance cover 130.
[0208] When the maintenance cover 130 is installed in place, several second heat dissipation holes correspond one-to-one with several first heat dissipation holes 112.
[0209] In some embodiments of this application, to ensure the installation stability of the side panel 132 of the maintenance cover 130, see [reference needed]. Figure 13 Receiving slots 112A / 112B are also formed on the upper housing 110, and see [reference]. Figure 14 Correspondingly, embedded posts 138 / 138A are formed on the side panel 132 of the maintenance cover 130.
