Description

Technical Field

[0001] This utility model relates to the field of control panel technology, specifically to a control panel that is easy to expand. Background Technology

[0002] A control panel is a user interface commonly used on various electrical devices. It is typically mounted on the device's casing or installed independently on the device, and is used by users to operate and control the device's operation.

[0003] Existing control panels typically have multiple interfaces of various types pre-installed on their bodies to allow for connection and communication with other devices and modules.

[0004] Because the number of preset interfaces on the control panel is limited, it cannot connect to more devices. If more interfaces are added, they will be exposed when not in use, leading to oxidation and contamination, which can cause poor contact and affect usability. Furthermore, the fixed interface type can only be connected to the corresponding connector and cannot be replaced, reducing the versatility of the control panel. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 2 The present invention provides the following technical solution:

[0021] An expandable control panel includes a body 1, a touch screen 2, and a main control board 3. The main control board 3 is installed inside the body 1. The touch screen 2 is installed on the body 1 and is electrically connected to the main control board 3. The touch screen 2 is used to operate the control panel. The main control board 3 is based on existing mature technology and can be configured by the user as needed. It also includes several expansion modules and a locking module. The locking module is installed inside the body 1 and is used to fix the expansion modules to the side of the body 1. The expansion modules are used to expand the corresponding interface types and number of interfaces.

[0022] A connection interface 4 is installed on the side wall of the body 1. The connection interface 4 is electrically connected to the main control board 3. The connection interface 4 is used for communication and data transmission with the expansion module.

[0023] The expansion module includes an expansion interface socket 7, a connector 72, and a connection mechanism. The expansion interface socket 7 is detachably installed on the side of the body 1 via the connection mechanism and the locking module. A connector 72 and several connection mechanisms are installed on one side of the expansion interface socket 7. The connector 72 is adapted to the connection interface 4, allowing the connector 72 to be inserted into the connection interface 4. This enables the control circuit board inside the expansion interface socket 7 to communicate with the main control board 3. The control circuit board is based on existing mature technology and can be customized by the user as needed. The connection mechanism is adapted to the locking module. Several data interfaces 71 are provided on the outside of the expansion connector socket. A control circuit board is installed inside the expansion interface socket 7. The control circuit board is electrically connected to the connector 72 and the data interfaces 71, enabling the data interfaces 71 to communicate with the main control board 3 through the control circuit board, the connector 72, and the connection interface 4. The data interfaces 71 can be connected to corresponding connectors to enable communication between devices.

[0024] The connecting mechanism includes a fixed mounting and a limiting block 74. One end of the fixed rod 73 is fixedly installed at the expansion interface seat 7, and the other end of the fixed mounting is provided with a limiting block 74. The limiting block 74 is adapted to the insertion hole 11 opened on the side of the body 1. The limiting block 74 and the fixed rod 73 are inserted into the locking module through the insertion hole 11.

[0025] The locking module includes a knob 61, a damping sleeve 63, a connecting block 64, a fixing sleeve 65, and a connecting sleeve 68. The connecting sleeve 68 is fixedly installed inside the body 1. One end of the fixing sleeve 65 is inserted into the connecting sleeve 68 and the two are rotatably connected. The other end of the fixing sleeve 65 is fixedly connected to the knob 61 through the connecting block 64. The knob 61 is rotatably damped and installed on the rear side wall of the body 1 through the damping sleeve 63, so that the knob 61 can drive the fixing sleeve 65 through the connecting block 64. The internal rotation of the connecting sleeve 68 enhances the stability of the rotation of the fixed sleeve 65. The damping sleeve 63 allows the knob 61 to rotate with damping motion. Thus, under the action of friction, the locking mechanism will not rotate arbitrarily. The fixed sleeve 65 is provided with a locking hole 66 that matches the limiting block 74 and a locking groove 67 that matches the fixing rod 73. After the limiting block 74 is inserted into the locking hole 66, the fixed sleeve 65 is rotated, so that the fixing rod 73 is locked into the locking groove 67, thereby locking the connecting mechanism at the fixed sleeve 65.

[0026] The knob 61 is provided with an indicator line 62, which is used to indicate the position of the card hole 66, so that the user can insert the connecting structure into the card hole 66.

[0027] An interface board 5 is installed at the bottom of the main body 1. The interface board 5 is electrically connected to the main control board 3. The interface board 4 has several interfaces for communication between the control panel and other devices and equipment.

[0028] The specific implementation process is as follows:

[0029] When using this easily expandable control panel for interface expansion, first rotate knob 61 so that the indicator line 62 of knob 61 faces the socket 11 on the side of the body 1. At this time, the socket 11 is aligned with the slot 66. Then, the expansion interface base 7 can be installed on the side of the body 1. The connector 72 at the expansion interface base 7 is inserted into the connector 4 on the side of the body 1. At this time, the data interface 71, control circuit board, connector 72, connector 4 and main control board 3 are connected, and data transmission and communication can be performed. The limiting block 74 at the end of the fixing rod 73 of the expansion interface base 7 passes through the socket 11 and the buckle in sequence and is inserted into the fixing sleeve 65. Then rotate knob 61. Knob 61 drives the fixing sleeve 65 to rotate through the connecting block 64, so that the fixing rod 73 enters the slot 67. Due to the action of the limiting block 74, the fixing rod 73 cannot be pulled out from the fixing sleeve 65, and the expansion interface base 7 is fixed on the side of the body 1.

[0030] This easily expandable control panel uses locking module 6 to lock the connection mechanism at the expansion interface socket 7, thereby fixing the expansion interface socket 7 to both sides of the body 1 for connecting external devices to the control panel. When not in use, the expansion interface socket 7 can be detached. The small size of the control panel makes it easy to use. By replacing different expansion interface sockets 7, the type and number of corresponding interfaces can be changed, effectively improving the versatility of the control panel and meeting users' needs for different interfaces.
