Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an intelligent elevator knob. Background Technology

[0002] The common elevator car control devices on the market are generally set up as control box structures, which usually include a display, multiple mechanical / touch buttons for displaying a single floor (for example, there are at least 20 buttons for the 20th floor), housing, control circuit board, etc. The products are relatively large, have low integration, and have a relatively simple appearance.

[0003] In response, some elevator cars have begun to use more aesthetically pleasing and simple smart knobs as a replacement for the aforementioned elevator control box structure. Smart knobs typically include an encoder as a rotating component, and the encoder outputs contact signals as its inner and outer rings rotate relative to each other, allowing users to select floors by turning the knob. However, encoders have low structural strength and are prone to malfunction and damage when subjected to axial pressure. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an intelligent elevator knob.

[0005] An elevator smart knob includes: a chamber, the chamber wall having a force-bearing side; an encoder installed in the chamber and spaced apart from the force-bearing side; and a housing assembly with one end extending into the chamber, wherein the shortest distance between the housing assembly and the force-bearing side is less than the shortest distance between the encoder and the force-bearing side.

[0006] With this configuration, since the housing assembly is closer to the force-bearing side than the encoder, when the elevator smart knob is pressed by external force, the force-bearing side will touch the housing assembly first. Therefore, the external pressure will be transmitted to the housing assembly through the force-bearing side and will not touch the encoder. As a result, the encoder will not be subjected to axial pressing force, thus ensuring the stable use of the encoder.

[0007] In one embodiment, a housing assembly is also included, the housing assembly including a housing and the encoder, the encoder including an inner ring and an outer ring rotatable relative to each other, the housing assembly being connected to the inner ring and the housing being connected to the outer ring.

[0008] In one embodiment, the device further includes a screen assembly connected to the inner ring; the screen assembly cooperates with the housing to form the cavity, and the force-bearing side is located on the side wall of the screen assembly forming the cavity.

[0009] In one embodiment, the housing assembly includes a housing and an abutment block connected to one end of the housing near the force-bearing side, and the abutment block is connected to the inner ring and extends to the outer side of the encoder away from the housing.

[0010] In one embodiment, a limiting hole is provided at one end of the box body connected to the abutment block, a drive plate is provided inside the box body, and a light-emitting element is provided on the drive plate, the light-emitting element being limited within the limiting hole;

[0011] The outer shell has a light-transmitting part near the force-bearing side. One end of the outer shell is close to the limiting hole and has a concave light-concentrating groove. The light-concentrating groove corresponds to the position of the limiting hole, and the groove wall of the light-concentrating groove can concentrate the light emitted by the light-emitting element into the light-concentrating groove, and then conduct it to the light-transmitting part through the outer shell.

[0012] In one embodiment, a limiting mechanism is constructed between the chamber and the housing assembly along the force direction on the force-bearing side.

[0013] In one embodiment, the limiting mechanism includes a first limiting portion located on the outer periphery of the housing assembly and a second limiting portion located on the inner wall of the cavity, wherein the first limiting portion and the second limiting portion limit and abut against each other.

[0014] In one embodiment, one of the first limiting portion and the second limiting portion is configured as a protrusion and the other is configured as a groove, wherein the protrusion engages with the groove.

[0015] In one embodiment, the protrusion is configured as a hemispherical shape, and the groove wall is configured as an arc shape.

[0016] In one embodiment, the side of the box body away from the abutment block is provided as an inclined surface, and the inclined surface is inclined relative to the force-bearing side.

[0017] Compared to existing technologies, this utility model provides an intelligent elevator knob, comprising: a chamber, the chamber wall having a force-bearing side; an encoder installed in the chamber and spaced apart from the force-bearing side; and a housing assembly, one end of which extends into the chamber, wherein the shortest distance between the housing assembly and the force-bearing side is less than the shortest distance between the encoder and the force-bearing side. The encoder enables the knob's rotation function, and the housing assembly is subjected to axial force before the encoder, thus preventing the encoder installed in the chamber from being subjected to axial compressive force, thereby ensuring the encoder is not damaged and extending its service life.

[0035] Please see Figures 1-10This utility model provides an elevator smart knob 100. When the passenger presses the screen component 10, the force is transmitted to the box component 30 without affecting the encoder 23 inside the housing component 20, thus extending the service life of the encoder 23.

[0036] Please see Figures 1-3 In one embodiment, the elevator smart knob 100 includes a chamber 21, an encoder 23, and a housing assembly 30. The cavity wall forming the chamber 21 has a force-bearing side 111. The encoder 23 is installed in the chamber 21 and is spaced apart from the force-bearing side 111. One end of the housing assembly 30 extends into the chamber. The shortest distance between the housing assembly 30 and the force-bearing side 111 is less than the shortest distance between the encoder 23 and the force-bearing side 111.

[0037] Thus, since the housing assembly 30 is closer to the force-receiving side 111 than the encoder 23, when the elevator smart knob 100 is subjected to external pressing pressure, the force-receiving side 111 will touch the housing assembly 30 first. Therefore, the external pressure will be transmitted to the housing assembly 30 through the force-receiving side 111, without touching the encoder 23. As a result, the encoder 23 will not be subjected to axial pressing pressure, thereby ensuring the stable use of the encoder 23.

[0038] It is understandable that the force-bearing side 111 refers to the cavity wall of the chamber 21 where the user applies force to the elevator smart knob 100.

[0039] Preferably, the shortest distance between the housing assembly 30 and the force-bearing side 111 is 0, so that the housing assembly 30 and the force-bearing side 111 form a zero-gap fit.

[0040] In one embodiment, the elevator smart knob 100 further includes a housing assembly 20, which includes a housing 22 and an encoder 23. The encoder 23 is installed in a chamber 21 and connected to the housing 22. The encoder 23 includes an inner ring 231 and an outer ring 232 that are rotatable relative to each other. The housing assembly 30 is connected to the inner ring 231, and the housing 22 is connected to the outer ring 232.

[0041] Thus, the user can manipulate the housing 22 to rotate the encoder 23, causing its inner ring 231 and outer ring 232 to rotate relative to each other, thereby outputting an electrical signal. In this embodiment, the chamber 21 can be constructed separately from the housing 22, so the force-bearing side is located on the housing 22.

[0042] It should be explained that relative coaxial rotation means that the inner ring 231 and the outer ring 232 rotate around the same axis, and their rotation speed and direction can be different. Therefore, the housing assembly 30 connected to the inner ring 231 can also rotate relative to the outer shell 22. When using the elevator smart knob 100, the user only needs to rotate the outer shell 22 to trigger different contacts in the encoder 23 and send out corresponding electrical signals.

[0043] In one embodiment, the elevator smart knob 100 also includes a screen assembly 10, which is connected to the inner ring 231. The screen assembly 10 and the housing 22 cooperate to form a chamber 21. The force-receiving side 111 is located on the side wall of the chamber 21 formed by the screen assembly 10. Therefore, when the passenger presses the screen assembly 10, the pressing force will be transmitted to the force-receiving side 111.

[0044] Thus, the chamber 21 is enclosed by the screen assembly 10 and the outer shell 22. The screen assembly 10 is used to display floor information and for occupants to press.

[0045] Specifically, please see Figures 4-5 The screen assembly 10 includes a touch screen 11, a screen base 12, and a control board 13. The touch screen 11 can accept the operation commands of the passengers and provide real-time feedback information, such as the selected floor, elevator operation status, overload fire status, real-time weather, etc. The screen base 12 is used to fix the touch screen 11, and the control board 13 is also connected to the screen base 12.

[0046] Preferably, the side of the control panel 13 facing the housing assembly 30 is configured as the force-bearing side 111.

[0047] In this embodiment, the touch screen 11 and the control board 13 are respectively connected to both sides of the screen base 12 along the axial direction. The touch screen 11 and the control board 13 are electrically connected, and the housing assembly 30 abuts against the control board 13. When the touch screen 11 receives a passenger's command, it is pressed and then the pressing force is transmitted to the screen base 12. The screen base 12 then transmits the pressure to the control board 13. Since the housing assembly 30 abuts against the control board 13, the pressure on the control board 13 can be distributed to the housing assembly 30.

[0048] Furthermore, the screen base 12 has a protruding step 121 facing the touch screen 11. The inner wall of the step 121 abuts against the outer peripheral wall of the touch screen 11, thereby making the connection between the screen base 12 and the step 121 tighter. In this embodiment, the touch screen 11 is circular, and the screen base 12 is also circular. The step 121 is correspondingly a circular hollow protrusion, so that the inner wall of the step 121 abuts against the touch screen 11. After the two are tightly connected, the connection strength is further reinforced by adhesive bonding. In this embodiment, the control board 13 and the screen base 12 are connected by multiple screws.

[0049] Understandably, in other embodiments, the touch screen 11 and the screen base 12 can also be connected by clips or screws, and are not limited to the above-mentioned adhesive connection. The control board 13 is similar, and will not be described in detail here.

[0050] Please see Figure 10 In one embodiment, the housing assembly 30 includes a housing 31 and an abutment block 32, the abutment block 32 being connected to one end of the housing 31 near the force-bearing side 111, and the abutment block 32 being connected to the inner ring 231 and extending to the outer side of the encoder 23 away from the housing 31.

[0051] Thus, the housing assembly 30 is connected to the encoder 23 via the abutment block 32, and abuts against the force-bearing side and transmits force.

[0052] Preferably, the encoder 23 has a channel 233 along its axial direction, and the abutment block 32 passes through the channel 233 and abuts against the force-bearing side. Specifically, the force-bearing side can be the housing 22 or the screen assembly 10, or other components for the user to apply force.

[0053] In one embodiment, the force-bearing side is the screen assembly 10, which is connected to the inner ring 231 of the encoder 23. Since the relative rotation of the inner ring 231 and the outer ring 232 of the encoder 23 is necessary to achieve the relative rotation between the housing 22 and the screen assembly 10, the encoder 23, the screen assembly 10, and the housing assembly 20 obviously have the highest matching degree when arranged coaxially. Accordingly, the channel 233 is opened at the axis of the encoder 23, and the abutment block 32 passes through the channel 233 and abuts against the screen assembly 10. Therefore, the abutment block 32 abuts against the axis of the screen assembly 10, so the force on the screen assembly 10 can be better transmitted to the abutment block 32. Moreover, this arrangement allows the abutment block 32 to be located inside the encoder 23, making better use of space and reducing the volume occupied by the abutment block 32.

[0054] To better transfer the force on the screen assembly 10 to the housing assembly 30, in one embodiment, the housing 22 has an opening 221 into which a portion of the housing 31 extends and connects to the inner wall of the opening 221. Therefore, the force on the housing 22 can be transferred to the housing assembly 30 through direct connection with the housing 31. Furthermore, since occupants typically hold the housing 22 when using buttons, radial inward pressure is applied to the housing 22. This pressure is also directly transferred to the housing 31 through the contact between the housing 22 and the housing 31, without affecting the encoder 23.

[0055] Please see Figures 7-8 In one embodiment, a limiting hole 313 is provided at one end of the housing 31 connected to the abutment block 32. A drive plate 34 is provided inside the housing 31, and a light-emitting element 40 is provided on the drive plate 34. The light-emitting element 40 is limited within the limiting hole 313. A light-transmitting part 24 is provided near the force-bearing side 111 of the outer shell 22. One end of the outer shell 22 is near the limiting hole 313 and has a concave light-concentrating groove. The light-concentrating groove corresponds to the position of the limiting hole 313, and the groove wall of the light-concentrating groove can concentrate the light emitted by the light-emitting element 40 into the light-concentrating groove, and then conduct it to the light-transmitting part 24 by the outer shell 22.

[0056] In this way, the light-emitting element 40 can emit light outward through the light-transmitting part 24, thereby making the elevator smart knob 100 emit an aesthetically pleasing light, thus enhancing the appearance and texture of the elevator smart knob 100. Furthermore, since the light-concentrating groove has a concave light-concentrating surface, the light emitted by the light-emitting element 40 can be focused to a single point using the principle of a concave lens, thus forming a new light-emitting point. Moreover, the light-concentrating groove is located on the outer casing 22, which is closer to the light-transmitting part than the box assembly 30, thus allowing the light source to be closer to the external light-transmitting area, resulting in more uniform light.

[0057] Specifically, the wall of the focusing groove is curved. The focusing groove is located at the bottom of the outer shell 22 inside the chamber 21.

[0058] Preferably, the focusing groove is a spherical groove, so that the light converges at the center of the sphere. This results in more uniform light distribution and a closer distance to the light-transmitting part without increasing processing difficulty. The light-emitting element 40 can specifically be an LED chip.

[0059] In one embodiment, a limiting mechanism is constructed between the chamber 21 and the housing assembly 30 along the force direction of the force-bearing side 111, so that the force is further directly transmitted to the housing assembly 30 to avoid affecting the encoder 23.

[0060] In one embodiment, the limiting mechanism includes a first limiting part located on the outer periphery of the housing assembly 30 and a second limiting part located on the inner wall of the chamber 21, wherein the first limiting part and the second limiting part limit and abut against each other.

[0061] Specifically, please see Figures 8-9 The outer periphery of the end of the box 31 that extends into the opening 221 has a first limiting part, and the inner wall of the opening 221 has a second limiting part. The first limiting part and the second limiting part abut against each other. In this way, the abutting of the first limiting part and the second limiting part makes the connection between the box 31 and the outer shell 22 more stable, prevents the outer shell 22 from falling off the box 31, and also improves the stress transmission effect.

[0062] Of course, it is understandable that in other embodiments, the inner walls of the box body 31 and the opening 221 can also be directly connected by adhesive, welding or adding screws and other connecting parts, and are not limited to the mutual abutment of the first limiting part and the second limiting part as described above.

[0063] In one embodiment, one of the first limiting part and the second limiting part is configured as a protrusion 311, and the other is configured as a groove 222, with the protrusion 311 engaging with the groove 222. This results in a simple and durable structure.

[0064] In one embodiment, the protrusion 311 is configured as a hemispherical shape, and the groove wall of the groove 222 is configured as an arc shape.

[0065] Specifically, the protrusion 311 is located on the outer periphery of the box 31 and is hemispherical, while the groove wall of the groove 222 is arc-shaped, which facilitates the snap-fit ​​between the two and avoids interference during installation that could cause structural damage.

[0066] Preferably, in one embodiment, the hemispherical protrusion 311 is made of POM material, which has wear-resistant and self-lubricating properties. In daily use, it facilitates the assembly and engagement of the groove 222 on the inner wall of the opening 221 of the housing 22 with the protrusion 311, and its wear resistance extends its service life. In other embodiments, the protrusion 311 can also be made of other materials with wear-resistant and elastic properties, such as rubber.

[0067] Furthermore, in one embodiment, a plurality of protrusions 311 are provided along the outer periphery of the housing 31 and are evenly spaced, while the grooves 222 are provided corresponding to the protrusions 311 to further ensure the connection strength between the outer shell 22 and the housing 31.

[0068] In one embodiment, the side of the box body 31 away from the abutment block 32 is provided as an inclined surface 312, which is inclined relative to the force-bearing side 111.

[0069] Thus, when installing the elevator smart knob in this embodiment, the force-bearing side can be oriented towards the user, resulting in a better human-computer interaction experience.

[0070] Specifically, the housing assembly 30 also includes a back plate 33. The side of the housing 31 away from the abutment block 32 is set as an inclined surface 312. The inclined surface 312 is inclined relative to the plane of the housing 31 near the screen assembly 10, and the housing 31 is set as a hollow structure. The back plate 33 covers the inclined surface 312. Thus, the screen assembly 10 can face the human eye directly, which is convenient for operation and recognition.

[0071] Compared to existing technologies, this utility model provides an intelligent elevator knob, comprising: a chamber, the chamber wall having a force-bearing side; an encoder installed in the chamber and spaced apart from the force-bearing side; and a housing assembly, one end of which extends into the chamber, wherein the shortest distance between the housing assembly and the force-bearing side is less than the shortest distance between the encoder and the force-bearing side. The encoder enables the knob's rotation function, and the housing assembly is subjected to axial force before the encoder, thus preventing the encoder installed in the chamber from being subjected to axial compressive force, thereby ensuring the encoder is not damaged and extending its service life.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
