Description

Technical Field

[0001] This application relates to the technical field of elevator control devices, and more particularly to an elevator control cabinet. Background Technology

[0002] In recent years, there has been a growing demand for miniaturization in the field of electrical equipment. Miniaturization requires compact design, which results in less internal space for the equipment. For example, in control equipment, after the main circuit components are installed, there is very little space left. There is no extra space to set up a fixed bracket to install other functional components such as interactive modules. Therefore, how to properly install functional components in the limited space of control equipment is an urgent problem to be solved. Summary of the Invention

[0003] This application provides an elevator control cabinet that enables stable installation of interactive devices while ensuring the compactness of the elevator control cabinet structure.

[0004] The elevator control cabinet includes an interactive device and a control cabinet body. The interactive device includes a housing. The control cabinet body includes a casing. The casing includes a main body and a fixing part. The main body has a receiving cavity, and an opening communicating with the receiving cavity is formed on the surface of the main body. The fixing part is connected to the main body and covers the opening to form part of the casing. The fixing part is connected to the housing.

[0005] Based on the elevator control cabinet of this application embodiment, the outer shell of the elevator control cabinet body is provided with a fixing part, which is fixedly connected to the outer shell of the interactive device to achieve the fixing of the interactive device. In this way, the interactive device is fixed in the small internal space of the control cabinet body without the need to specially set up a fixing bracket for fixing the interactive device.

[0006] In some embodiments of this application, the outer shell has a connecting cavity, and the fixing part includes a body sub-part and a connecting sub-part. The body sub-part is connected to the main body part; the connecting sub-part is connected to the body sub-part, and the connecting sub-part is inserted into the connecting cavity.

[0007] Based on the above embodiments, the connection between the main body sub-part of the fixing part and the main body part realizes the connection between the fixing part and the main body part. The connecting sub-part of the fixing part is located in the connecting cavity and fits against the cavity wall of the connecting cavity, thus realizing the connection between the fixing part and the shell of the interactive device and the limitation of the degree of freedom of the interactive device.

[0008] In some embodiments of this application, the number of fixing parts is two, and the two fixing parts are located on opposite sides of the outer shell.

[0009] Based on the above embodiments, the two fixing parts can provide a better fixing effect on the interactive device. At the same time, by setting the two fixing parts on opposite sides of the outer shell, multiple positions of the interactive device can be fixed, thereby enhancing the fixing effect of the fixing parts on the interactive device.

[0010] In some embodiments of this application, the housing further includes a reinforcing portion, the two ends of which are respectively connected to the two fixing portions, and the reinforcing portion abuts against the outer shell. After the reinforcing portion covers the opening portion, the main body, the reinforcing portion, and the two fixing portions surround an assembly opening.

[0011] Based on the above embodiments, the two ends of the reinforcing part are respectively connected to two fixed parts. Thus, the two fixed parts and the reinforcing part can be simplified into a statically indeterminate beam (the connection between the fixed part and the first shell can be simplified into a cantilever beam). Thus, the two fixed parts and the reinforcing part, which are simplified into a statically indeterminate beam, together provide better support for the interactive device. In addition, the reinforcing part abuts against the outer shell to further limit the degree of freedom of the interactive device, so as to make the interactive device more stable.

[0012] In some embodiments of this application, the housing has an assembly opening, the interactive device has an interactive surface remote from the first circuit board assembly, and the interactive device partially passes through the assembly opening to expose the interactive surface outside the housing.

[0013] Based on the above embodiments, the interactive surface of the interactive device is exposed outside the housing through the assembly opening, which makes it convenient for the user to give commands to the interactive device and read data.

[0014] In some embodiments of this application, the control cabinet body further includes a first circuit board assembly, which is fixed inside the housing. Along the thickness direction of the interactive device, the fixing part coincides with the high-voltage part of the first circuit board assembly.

[0015] Based on the above embodiments, along the thickness direction of the interactive device, the fixing part overlaps with the high-voltage part of the first circuit board assembly to achieve isolation from high voltage and protect the user's safety.

[0016] In some embodiments of this application, the first circuit board assembly is provided with a snap-fit ​​portion; the housing is provided with a locking portion, and the interactive device is detachably fixed to the first circuit board assembly through the snap-fit ​​engagement of the locking portion and the snap-fit ​​portion.

[0017] Based on the above embodiments, the outer shell of the interactive device is provided with a locking part, and the first circuit board assembly of the corresponding control cabinet body is provided with a locking part. The interactive device is detachably fixed to the first circuit board assembly through the locking engagement of the locking part and the locking part. In this way, the first circuit board assembly provides auxiliary fixation for the interactive device to improve the stability of the interactive device.

[0018] In some embodiments of this application, the first circuit board assembly includes a plurality of first printed circuit boards, which are arranged along the thickness direction of the interactive device, and the housing is snapped onto the first printed circuit board closest to it along the thickness direction of the interactive device; or,

[0019] Along the thickness direction of the interactive device, the portion of the first printed circuit board adjacent to the assembly opening has a first clearance opening, and the first clearance opening at least partially overlaps with the assembly opening in the thickness direction of the interactive device. The housing at least partially passes through the first clearance opening and engages with the first printed circuit board closest to the assembly opening that does not have the first clearance opening.

[0020] Based on the above embodiments, when multiple first printed circuit boards are arranged along the thickness direction of the interactive device, when the outer casing is connected to the first printed circuit board closest to itself, the installation difficulty of the interactive device can be reduced, which is suitable for interactive devices with small size.

[0021] When the outer casing is connected to the first printed circuit board (excluding the one closest to it), the first printed circuit board, which is higher than the first printed circuit board connected to the outer casing along the thickness direction of the interactive device, has a first clearance opening to avoid the interactive device, so that the outer casing of the interactive device can pass through the first clearance opening to connect with the corresponding first printed circuit board. This is suitable for interactive devices with a large volume.

[0022] In some embodiments of this application, the outer casing is provided with a positioning part, and a positioning cavity is provided corresponding to the first printed circuit board, and the positioning part is inserted into the positioning cavity.

[0023] Based on the above embodiments, when the interactive device is assembled with the first circuit board assembly, the positioning part is placed in the positioning cavity to achieve alignment of the outer shell and the first circuit board assembly, thereby facilitating the subsequent assembly of the fixing parts with the interactive device and the connection between the interactive device and the first circuit board assembly.

[0024] In some embodiments of this application, the length of the positioning portion is greater than the length of the snap-fit ​​portion along the thickness direction of the interactive device.

[0025] Based on the above embodiments, the length of the positioning part is greater than the length of the snap-fit ​​part, which can ensure that the interactive device and the positioning component are aligned. At this time, pressure can be applied to the interactive device to deform the snap-fit ​​part and pass through the snap-fit ​​interface to snap-fit ​​with the printed circuit board. This facilitates the assembly of the interactive device and the printed circuit board and protects the printed circuit board during the assembly of the two.

[0026] In some embodiments of this application, the housing further includes a cover portion, which is connected to the main body portion and covers the opening, and is located on the side of the fixing portion opposite to the first circuit board assembly;

[0027] The cover portion is provided with a recess corresponding to the interactive device, and the interactive device is exposed through the recess.

[0028] Based on the above embodiments, the cover improves the airtightness of the control cabinet body by covering the opening when the cover is in the closed state. In addition, the cover has a recessed opening that exposes the interaction surface of the interactive device when the cover is in the closed state, so that the user can operate the elevator control cabinet.

[0029] Based on the elevator control cabinet of this application embodiment, the outer shell of the main body of the elevator control cabinet is provided with a fixing part, which is fixedly connected to the outer shell of the interactive device to fix the interactive device. In this way, without the need to specially set up a fixing bracket for fixing the interactive device in the small internal space of the control cabinet body, the elevator control cabinet can be assembled at the same time, which is conducive to its miniaturization.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] In recent years, there has been a growing demand for miniaturization in the field of electrical equipment. Miniaturization requires compact design, which results in less internal space for the equipment. For example, in control equipment, after the main circuit components are installed, there is very little space left. There is no extra space to set up a fixed bracket to install other functional components such as interactive modules. Therefore, how to properly install functional components in the limited space of control equipment is an urgent problem to be solved.

[0040] To solve the above technical problems, please refer to Figures 1 to 4 As shown, this application proposes an elevator control cabinet that can achieve stable installation of the interactive device 20 while ensuring the structural compactness of the elevator control cabinet.

[0041] Please refer to Figures 1 to 4As shown, the elevator control cabinet includes an interactive device 20 and a control cabinet body 10. The interactive device 20 includes a housing 21, and the control cabinet body 10 includes a housing 11. The housing 11 includes a main body 112 and a fixing part 113. The main body 112 has a receiving cavity 1122, and an opening 1121 communicating with the receiving cavity 1122 is formed on the surface of the main body 112. The fixing part 113 is connected to the main body 112 and covers part of the opening 1121 to form part of the housing 11. The fixing part 113 is connected to the housing 21.

[0042] The housing 11 is the outer shell of the elevator control cabinet body 10, used to house the first circuit board assembly 12 and the interactive device 20. In this application embodiment, the size, shape, material, and processing technology of the housing 11 are not limited. Regarding the shape of the housing 11, since the elevator control cabinet is usually fixed to the ground, in some embodiments of this application, the housing 11 is configured as a rectangular structure to facilitate installation. Regarding the material of the housing 11, in some embodiments of this application, the housing 11 is made of insulating material or is made of non-insulating material but its surface is coated with an insulating coating. Regarding the forming process of the housing 11, in some embodiments of this application, the housing 11 is configured as a sheet metal part. Sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / compound cutting, bending, welding, riveting, and splicing. Products processed through sheet metal processing are called sheet metal parts.

[0043] The outer casing 21 is the outer casing of the interactive device 20, used to accommodate the second circuit board assembly 22 and connect it to the first circuit board assembly 12. In this embodiment, the size, shape and material of the casing 11 are not limited.

[0044] The main body 112 is the main part of the housing 11. In some embodiments of this application, the main body 112 is configured as a sheet metal part, so that the main body 112 can form a receiving cavity 1122 during the sheet metal process. Regarding the shape of the main body 112, in some embodiments of this application, the main body 112 is configured as a rectangular structure, the corresponding assembly opening 111 is configured as a rectangle, and the outer shell 21 is configured as a cuboid. It can be understood that the shape of the main body can be configured as any shape.

[0045] The receiving cavity 1122 is used to accommodate the interactive device 20 and the first circuit board assembly 12. Combined with the main body 112, which is configured as a sheet metal part, in some embodiments of this application, the receiving cavity 1122 is configured as a rectangular cavity, and the receiving cavity 1122 forms an opening 1121 on the side of the main body 112 away from the first circuit board assembly 12. It is understood that the receiving cavity 1122 can be configured in any shape.

[0046] The fixing part 113 forms part of the housing 11 and further fixes the interactive device 20. Combined with the main body 112, it is configured as a sheet metal part. In some embodiments of this application, the fixing part 113 is configured as a sheet metal part and integrally formed with the main body 112, which facilitates the processing and forming of the outer shell 21 of the interactive device 20.

[0047] Based on the elevator control cabinet of this application embodiment, the outer shell 21 of the elevator control cabinet body 10 is provided with a fixing part 113. The fixing part 113 is fixedly connected to the outer shell 21 of the interactive device 20 to fix the interactive device 20. In this way, without the need to specially set up a fixing bracket for fixing the interactive device 20 in the small internal space of the control cabinet body 10, the interactive device 20 can be assembled while maintaining the compactness of the elevator control cabinet, which is conducive to its miniaturization.

[0048] Please refer to Figure 3 as well as Figure 6 or Figure 4 as well as Figure 6 As shown, in some embodiments of this application, the outer shell 21 has a connecting cavity 212, and the fixing part 113 includes a body sub-part 1131 and a connecting sub-part 1132. The body sub-part 1131 is connected to the main body part 112; the connecting sub-part 1132 is connected to the body sub-part 1131, and the connecting sub-part 1132 is inserted into the connecting cavity 212.

[0049] The body sub-part 1131 is used to connect the main body part 112 and cover the opening 1121. In some embodiments of this application, the body sub-part 1131 is configured as a rectangular piece.

[0050] The connecting sub-part 1132 is located within the connecting cavity 212 and cooperates with the connecting cavity 212 to connect the fixing part 113 and the outer shell 21. In some embodiments of this application, the connecting sub-part 1132 is configured as a plate-like structure. It is understood that the number of connecting sub-parts 1132 connected to one body sub-part 1131 can be multiple, and the corresponding outer shell 21 has multiple connecting cavities 212. The connecting sub-part 1132 can also be configured in other arbitrary shapes. For example, the connecting sub-part 1132 can be configured as a cylindrical structure or a conical structure, as long as the connecting sub-part 1132 can be assembled into the connecting cavity 212 and fit against the cavity wall of the connecting cavity 212, and the shape of each connecting sub-part 1132 can be different.

[0051] The connecting cavity 212 is used to accommodate the connecting sub-part 1132. After the connecting sub-part 1132 is placed in the connecting cavity 212, the fixing part 113 is connected to the outer shell 21. In combination with the above-mentioned connecting sub-part 1132 being configured as a plate-like structure, in some embodiments of this application, the connecting cavity 212 is configured as a rectangular cavity. It is understood that the connecting cavity 212 can also be configured as other shapes, but it should be ensured that the shape of the connecting cavity 212 corresponds to the shape of the connecting sub-part 1132 so that the connecting sub-part 1132 can be assembled into the connecting cavity 212. For example, when the connecting sub-part 1132 is configured as a cylindrical structure, the connecting cavity 212 is configured as a cylindrical cavity.

[0052] Please refer to Figure 2 as well as Figure 5 As shown, in some embodiments of this application, there are two fixing parts 113, which are located on opposite sides of the outer casing 21. In this way, the two fixing parts can have a better fixing effect on the interactive device. At the same time, by setting the two fixing parts on opposite sides of the outer casing, multiple positions of the interactive device can be fixed, thereby enhancing the fixing effect of the fixing parts on the interactive device.

[0053] Please refer to Figure 2 as well as Figure 5 As shown, in some embodiments of this application, the housing 11 further includes a reinforcing part 114, the two ends of which are respectively connected to two fixing parts 113, and the reinforcing part 114 abuts against the outer shell 21. The main body 112, the reinforcing part 114 and the two fixing parts 113 surround an assembly opening 111.

[0054] The reinforcing part 114 is used to strengthen the support strength of the two fixed parts 113 for the interactive device 20. Before the reinforcing part 114 is provided, one end of the reinforcing part 114 is connected to the main body 112 and the other end is connected to the outer shell 21. At this time, the reinforcing part 114 can be simplified as a cantilever beam, which has poor stability for the interactive device 20. After the two fixed parts 113 are connected to the two ends of the reinforcing part 114 respectively, the reinforcing part 114 and the two fixed parts 113 constitute a statically indeterminate beam, which has a better stabilizing effect on the interactive device 20. Among them, the cantilever beam is a simplified model obtained in mechanics of materials for the convenience of calculation and analysis. One end of the cantilever beam is a fixed support and the other end is a free end. A statically indeterminate beam is a beam in which the number of support reactions is greater than the effective equilibrium equation. In this application, the statically indeterminate beam formed by the reinforcing part 114 and the two fixed parts 113 constrains all the free ends of the beam. In some embodiments of this application, the reinforcing part 114 is configured as a rectangular piece.

[0055] Please refer to Figures 1 to 3As shown, in some embodiments of this application, the housing 11 has an assembly opening 111, and the interactive device 20 has an interactive surface 23 away from the first circuit board assembly 12. The interactive device 20 partially passes through the assembly opening 111 so that the interactive surface 23 is exposed outside the housing 11.

[0056] Assembly opening 111 is used to expose the interaction surface 23 of the interaction device 20 outside the housing 11, so that the user can give instructions to the interaction device 20 and read data. It is understood that the shape and size of assembly opening 111 should be set according to the size and shape of the interaction device 20. In some embodiments of this application, the outer surface of the housing 21 is attached to the cavity wall of assembly opening 111.

[0057] The interaction surface 23 is the side of the interaction device 20 that the user can operate. It can be understood that the interaction surface 23 is equipped with operation buttons and display devices, etc.

[0058] Please refer to Figure 2 As shown, in some embodiments of this application, the control cabinet body 10 further includes a first circuit board assembly 12, which is fixed inside the housing 11. Along the thickness direction a of the interactive device, the fixing part 113 overlaps with the high-voltage part of the first circuit board assembly 12.

[0059] The first circuit board assembly 12 is used to receive signals from the second circuit board assembly 22 to control the elevator. It is understood that the first circuit board assembly 12 may include at least one first printed circuit board 121. The first printed circuit board 121 may be a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit). Since a PCB is a rigid printed circuit board, it has a better support effect for the interactive device 20. Preferably, the first printed circuit board 121 is a PCB.

[0060] Please refer to Figure 4 As shown, in some embodiments of this application, the interactive device 20 further includes a second circuit board assembly 22, which is fixed inside the housing 21 and electrically connected to the first circuit board assembly 12.

[0061] The second circuit board assembly 22 is used to receive instructions applied by the user to the interactive device 20 and send the instructions to the first circuit board assembly 12 in the form of electrical signals. At the same time, the second circuit board assembly 22 receives feedback information from the first circuit board assembly 12 and transmits the feedback information to the interactive device 20 in the form of electrical signals. It is understood that the second circuit board assembly 22 may include at least one second printed circuit board, which may be a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit).

[0062] Please refer to Figure 4 as well as Figure 6 As shown, in some embodiments of this application, the first circuit board assembly 12 is provided with a snap-fit ​​portion 122; the housing 21 is provided with a snap-fit ​​portion 211, and the interactive device 20 is detachably fixed to the first circuit board assembly 12 through the snap-fit ​​engagement of the snap-fit ​​portion 211 and the snap-fit ​​portion 122.

[0063] The latching portion 122 cooperates with the engaging portion 211 to connect the interactive device 20 to the first circuit board assembly 12. The first circuit board assembly 12 includes at least one first printed circuit board 121, and the interactive device 20 can be connected to any of the first printed circuit boards 121. In some embodiments of this application, the latching portion 122 is configured as a card interface that penetrates the first printed circuit board 121. The engaging portion 211 includes a main body portion and an engaging portion. The main body portion is connected to the outer shell 21 and extends toward the corresponding first printed circuit board 121, passing through the card interface so that part of the main body portion is located on the side of the corresponding first printed circuit board 121 away from the interactive device 20. The engaging portion connects to and abuts against the part of the main body portion on the first printed circuit board 121 away from the interactive device 20. Thus, the engaging portion 211, in cooperation with the latching portion 122, achieves the connection between the interactive device 20 and the first circuit board assembly 12. It is understood that the main body portion can deform, and the engaging portion can pass through the card interface. Furthermore, in this embodiment, the number of latching parts 122 and latching parts 211 is not limited, and any number of latching parts 122 and latching parts 211 can achieve the connection between the interactive device 20 and the first circuit board assembly 12.

[0064] In some embodiments of this application, a plurality of first printed circuit boards 121 are arranged along the thickness direction a of the interactive device 20, and the housing 21 is connected to the first printed circuit board 121 closest to itself. Thus, since the housing 21 is connected to the first printed circuit board 121 closest to itself, it is suitable for the connection between the interactive device 20 and the first circuit board assembly 12 when the size of the interactive device 20 is small.

[0065] Please refer to Figure 2 as well as Figure 5 As shown, in some other embodiments of this application, along the thickness direction a of the interactive device 20, a portion of the first printed circuit board 121 adjacent to the assembly opening 111 has a first clearance opening 124, and the first clearance opening 124 at least partially overlaps with the assembly opening 111 in the thickness direction a of the interactive device 20. The housing 21 at least partially passes through the first clearance opening 124 and engages with the first printed circuit board 121 closest to the assembly opening 111 that does not have the first clearance opening 124. Thus, the interactive device 20 connects to the corresponding first printed circuit board 121 through at least one first clearance opening 124.

[0066] In some other embodiments of this application, a plurality of first printed circuit boards 121 are at the same height along the thickness direction a of the interactive device 20, and the outer casing 21 is connected to any of the first printed circuit boards 121. In this case, since the plurality of first printed circuit boards 121 are at the same height along the thickness direction a of the interactive device 20, the interactive device 20 can be connected to any of the first printed circuit boards 121.

[0067] Please refer to Figure 2 as well as Figure 5 As shown, in some embodiments of this application, the first printed circuit board 121 connected to the housing 21 has a second clearance opening 125, one of the remaining first printed circuit boards 121 is provided with a first power contact portion 1211, and the second circuit board assembly 22 has a second power contact portion 221 exposed to the housing 21. The second power contact portion 221 passes through the second clearance opening 125 and is electrically connected to the first power contact portion 1211.

[0068] The second clearance opening 125 is used to avoid the second power contact portion 221 of the second circuit board assembly 22. In this embodiment, the shape, size, and number of the second clearance opening 125 are not limited. Any size and shape of the second clearance opening 125 is acceptable as long as it can avoid the second power contact portion 221. However, the arrangement of the second clearance opening 125 should ensure that it does not damage the printed circuit on the first printed circuit board 121. When there are multiple second power contacts 221, the number of second clearance openings 125 can be multiple to avoid multiple second power contacts 221. It is understood that the first power contact portion 1211 and the second power contact portion 221 can be connected by a cable.

[0069] Please refer to Figure 2 as well as Figure 6 As shown, in some embodiments of this application, a positioning part 213 is provided on the outer shell 21, and a positioning cavity 123 is provided on the first circuit board assembly 12. The positioning part 213 is located inside the positioning cavity 123 and fits against the cavity wall of the positioning cavity 123.

[0070] The positioning part 213 cooperates with the positioning cavity 123 to align the interactive device 20 with the first circuit board assembly 12. In some embodiments of this application, the positioning part 213 is configured as a positioning pin, and the shape of the positioning pin is not limited in the embodiments of this application. For example, the positioning pin can be a cylindrical structure, a prism structure, or an inverted frustum structure, etc. Since the housing 21 is provided with both the positioning part 213 and the engaging part 211, in some embodiments of this application, the positioning part 213 and the engaging part 211 are arranged alternately.

[0071] The positioning cavity 123 is used to accommodate the positioning part 213 or to allow the positioning part 213 to pass through. In the embodiments of this application, the shape of the positioning cavity 123 corresponds to the shape of the positioning part 213. For example, when the positioning pin is cylindrical, the positioning cavity 123 is cylindrical; when the positioning pin is frustum, the positioning cavity 123 is cylindrical or frustum; when the positioning pin is prism, the positioning cavity 123 is prism. In some embodiments of this application, the positioning cavity 123 and the engaging part 211 are alternately arranged in conjunction with the positioning part 213 and the engaging part 211.

[0072] Please refer to Figure 3 or Figure 4 As shown, in some embodiments of this application, along the thickness direction a of the interactive device 20, the length of the positioning part 213 is greater than the length of the latching part 122. Thus, the length of the positioning part 213 being greater than the length of the latching part 122 ensures that the interactive device 20 and the positioning component are aligned. At this time, pressure can be applied to the interactive device 20 to deform the latching part 122 through the card interface to latch with the printed circuit board. This facilitates the assembly of the interactive device 20 and the printed circuit board and protects the printed circuit board during the assembly.

[0073] Please refer to Figure 1 as well as Figure 2 As shown, in some embodiments of this application, the housing 11 further includes a cover portion 115, which is connected to the main body portion 112 and covers the opening 1121, and is located on the side of the fixing portion 113 away from the first circuit board assembly 12; the cover portion 115 is provided with a clearance opening 1151 corresponding to the interactive device 20, and the interactive surface 23 of the interactive device 20 is exposed by the clearance opening 1151.
