[0037] When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0038] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0040] In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0041] In order to solve the technical problems in the prior art that it is difficult to separately disassemble one of the combined multiple circuit boards, and the length and width of such circuit boards are relatively large, which requires more installation area inside the device.

[0042] The following details the specific structure of a circuit board 1 of an elevator controller provided by an embodiment of the present utility model. As shown in the attached Figures 1-4 drawings, the specific structure of the circuit board 1 of the elevator controller includes at least two circuit boards 1, a plurality of splicing members 3, and a connection assembly 4.

[0043] A lifting frame 2 is provided on the previous circuit board 1; a connection port 11 is provided on the subsequent circuit board 1.

[0044] For example, in the embodiment of the present utility model, at least two circuit boards 1 are provided. The previous circuit board 1 is arranged above the subsequent circuit board 1. In order to electrically connect the two circuit boards 1 to each other, the entire connection assembly 4 is driven by the lifting frame 2 to move downward until it can be connected to the connection port 11 on the subsequent circuit board 1, so that the previous circuit board 1 is electrically connected to the subsequent circuit board 1.

[0045] A plurality of splicing members 3 are stacked, each splicing member 3 is detachably connected to the adjacent splicing member 3, and each circuit board 1 is detachably arranged on the side of each splicing member 3.

[0046] Specifically, in order to improve the utilization rate of the installation space inside the device and minimize the installation area occupied by the circuit board 1 with a relatively large area inside the device, each circuit board 1 is detachably assembled on each splicing member 3 respectively. Subsequently, each splicing member 3 is assembled with the adjacent splicing member 3 to stack multiple circuit boards 1, further reducing the occupation of the installation area inside the device. More specifically, when each circuit board 1 is detachably assembled on each splicing member 3, the sides of each circuit board 1 are arranged opposite to the sides of the adjacent circuit board 1, that is, the previous circuit board 1 is directly above the subsequent circuit board 1. With this arrangement, more installation space inside the device is saved, enabling more electronic components and connection lines to be accommodated within the limited space inside the device, thereby improving the integration degree of the circuit board 1.

[0047] When it is necessary to disassemble each circuit board 1, only need to disassemble each circuit board 1 from each splicing member 3 respectively, and then each circuit board 1 can be taken out.

[0048] According to Figure 4 As shown, the connection component 4 includes a connector 41 and a flexible cable; the connector 41 is movably arranged on the lifting frame 2, one end of the flexible cable is connected to the connector 41, and the other end is connected to the previous circuit board 1. When the connector 41 moves downward and is inserted into the connection port 11 on the subsequent circuit board 1, the adjacent upper and lower circuit boards 1 are electrically connected to each other.

[0049] Specifically, since each circuit board 1 is stacked, in order to electrically connect each circuit board 1 to each other, therefore, the connector 41 moves along the direction of the other circuit board 1 on the lifting frame 2 provided on one of the circuit boards 1 until the connector 41 can be inserted into the connection port 11 on the circuit board 1. Since both ends of the flexible cable are connected to the connector 41 and the upper-layer circuit board 1 respectively, when the connector 41 is inserted into the connection port 11 on the lower-layer circuit board 1, the two circuit boards 1 are electrically connected to each other.

[0050] Combined with the above, for example, two circuit boards 1 are provided in total. After the two circuit boards 1 are respectively assembled on each splicing member 3, since the previous circuit board 1 is directly above the subsequent circuit board 1 and the lifting frame 2 is provided on the previous circuit board 1, only need to move the connector 41 downward on the lifting frame 2 until it can be inserted into the connection port 11 on the subsequent circuit board 1, thereby further improving the utilization rate of the space inside the device. Different from a single large circuit board 1, it saves the installation area required inside the device, and then reduces the external dimensions of the device, which is more conducive to improving the use efficiency of the internal space of the device.

[0051] In addition, when the electronic components and circuits on a certain circuit board 1 are damaged, it is only necessary to disconnect the connector 41 from the connection port 11, and then remove the circuit board 1 from the splicing member 3. At this time, the circuit board 1 can be taken out, thereby improving the convenience during the assembly of each circuit board 1.

[0052] In some specific embodiments, protrusions are provided on the tops of the splicing members 3, and grooves are recessed on the bottoms of the splicing members 3; the protrusions of each splicing member 3 are inserted into the grooves of the adjacent splicing members 3.

[0053] Specifically, in order to improve the portability and stability of the assembly of each splicing member 3 with the adjacent splicing member 3, therefore, since the shapes of the protrusions are adapted to the shapes of the grooves, when assembling each splicing member 3, it is only necessary to insert the bottom protrusion of the previous splicing member 3 into the groove of the next splicing member, and then each circuit board 1 can be respectively assembled on each splicing member 3; conversely, when disassembling each splicing member 3, it is only necessary to separate the bottom protrusion of the previous splicing member 3 from the groove of the next splicing member, and then the two splicing members 3 can be separated.

[0054] It can be understood that one or more protrusions are provided on the protrusion of the previous splicing member 3 in the embodiment of the present utility model. Correspondingly, the number of grooves of the next splicing member 3 corresponds to the number of protrusions one by one. Therefore, each splicing member 3 is respectively inserted into each groove, and the specific number of protrusions and grooves is not limited herein.

[0055] In a further embodiment, fixing holes are provided on the sides of each protrusion, and locking holes for corresponding communication with the fixing holes are penetrated through the groove walls of each groove; the circuit board 1 further includes a locking member 5. When the locking member 5 passes through the locking hole and the fixing hole at the same time, the two adjacent splicing members 3 are fixedly connected.

[0056] Specifically, in order to further improve the convenience during the disassembly and assembly of each splicing member 3, and at the same time, prevent the splicing members 3 from easily falling off, after inserting the bottom protrusion of each splicing member 3 into the groove of the adjacent splicing member 3, it is only necessary to correspondently communicate the fixing hole on the protrusion with the locking hole on the groove, and then insert the locking member 5 into the locking hole and the fixing hole at the same time, so that the protrusion of the previous splicing member 3 is fixed in the groove of the next splicing member 3. With this setting, the convenience of the assembly of the previous splicing member 3 and the next splicing member 3 is improved; conversely, when separating and disassembling the two splicing members 3, it is only necessary to separate the locking member 5 from the fixing hole and the locking hole, and then separate the bottom protrusion of the previous splicing member 3 from the groove of the next splicing member 3, and then the two splicing members 3 can be separated.

[0057] It can be understood that the aforementioned locking member 5 is a bolt, and the fixing hole and the locking hole are both threaded holes. By connecting the thread of the bolt with the thread in each threaded hole, in this way, the previous splicing member 3 and the next splicing can be fixedly connected, thereby improving the firmness of the two.

[0058] According to Figure 4 As shown, in some specific embodiments, the lifting frame 2 includes a support portion 21 and a movable portion 22. The support portion 21 is disposed on one of the circuit boards 1, and a first guide rail 211 extending vertically is provided on the side surface of the support portion 21; the connection head 41 is disposed on the movable portion 22, and the movable portion 22 is slidably disposed on the first guide rail 211.

[0059] Specifically, in order to stably insert the connection head 41 into the connection port 11 on another circuit board 1, for this purpose, the connection head 41 is disposed on the movable portion 22. Since the first guide rail 211 is vertically disposed and is used to guide the moving direction of the connection head 41, when the movable portion 22 moves on the first guide rail 211, it can drive the connection head 41 to move downward until the connection head 41 is inserted into the connection port 11 on the lower circuit board 1; when disassembling the two circuit boards 1, move the movable portion 22 on the first guide rail 211 until it can drive the connection head 41 to move upward until the connection head 41 is separated from the connection port 11 on the lower circuit board 1.

[0060] According to Figure 1 As shown, in a further embodiment, a relief opening 12 for the lifting and moving of the movable portion 22 is formed through one of the circuit boards 1, and the relief opening 12 is disposed opposite to the connection port 11 of the lower circuit board 1.

[0061] Specifically, since some of the connection ports 11 are disposed at different positions on the side surface of the circuit board 1, in order to enable the connection head 41 to be directly inserted into the connection port 11 when descending, a relief opening 12 is formed through the upper circuit board 1 and the relief opening 12 is located in the moving direction of the movable portion 22. With this setting, when the movable portion 22 moves up or down on the first guide rail 211, the movable portion 22 can pass through the upper circuit board 1 through the relief opening 12, so that the connection head 41 can be inserted into the connection port 11 on the lower circuit board 1.

[0062] According to Figure 1 As shown, the embodiment of the present invention further includes a plurality of support components 6, all of which are used to support each circuit board 1.

[0063] Specifically, when each circuit board 1 is assembled on the splicing member 3, in order to improve the stability of each circuit board 1, a plurality of support components 6 are used to support each circuit board 1 to prevent each circuit board 1 from being damaged due to vibration or impact.

[0064] According to Figure 4As shown, specifically, each support component 6 includes a bracket 61 and multiple support blocks 62; multiple mounting grooves having the same height as the circuit board 1 are provided on the side surface of the bracket 61, and each support block 62 is detachably disposed in each mounting groove for respectively supporting each circuit board 1.

[0065] Specifically, the bottom of the bracket 61 is disposed on the mounting surface inside the device. Since the multiple mounting grooves on the side surface of the bracket 61 respectively have the same height as each circuit board 1 assembled on the splicing member 3, only by respectively assembling the multiple support blocks 62 in each mounting groove and making the top parts of the respective support portions 21 abut against the bottom of each circuit board 1, the effect of supporting each circuit board 1 can be achieved.

[0066] It can be understood that the connecting ends of the support blocks 62 in the embodiments of the present invention are respectively connected to the mounting grooves on the bracket 61 by snap connection or threaded connection, etc., and the specific connection method is not limited herein.

[0067] According to Figure 2 As shown, in some specific embodiments, second guide rails 31 with openings are formed on the side surfaces of the splicing members 3, and each circuit board 1 is slidably disposed in the second guide rails 31.

[0068] Specifically, multiple circuit boards 1 can be movably disposed in the second guide rails 31 of the splicing member 3. Specifically, when assembling the circuit board 1 on the splicing member 3, one side of the circuit board 1 is slidably disposed in the second guide rail 31 through the opening. At the same time, the positions of the circuit boards 1 on the second guide rail 31 can be adjusted according to actual requirements, that is, the circuit board 1 is moved on the second guide rail 31 to the target specified position until the side surfaces of the two circuit boards 1 in the upper and lower layers can be relatively disposed, thereby achieving the effect of respectively and quickly assembling each circuit board 1 on each splicing member 3 and also adjusting the positions of the circuit boards 1.

[0069] According to Figure 3 As shown, in a further embodiment, sliding blocks 32 are disposed in the second guide rails 31, and clamping portions 33 for clamping the circuit board 1 are provided on the sliding blocks 32.

[0070] Specifically, when assembling the circuit board 1, the circuit board 1 is clamped by the clamping portion 33 to prevent the circuit board 1 from easily falling off. Subsequently, the sliding block 32 is slid on the second guide rail 31 to the specified target position, thereby achieving the effect of adjusting the position of the circuit board 1. When adjusting the positions of multiple circuit boards 1 on the same second guide rail 31, sliding blocks 32 corresponding to the circuit boards 1 one by one are provided on the second guide rail 31, and the multiple sliding blocks 32 all move on the same second guide rail 31, thereby achieving the effect of adjusting the positions of the multiple circuit boards 1.

[0071] When disassembling and removing the circuit board 1, it is only necessary to take out the whole circuit board 1 after detaching the circuit board 1 from the clamping part 33.

[0072] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
