For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The present embodiment provides an elevator button with a self-balancing function, which can avoid the situation in the prior art that one side of the elevator button is lifted up after the other side is pressed, thereby improving the pressing feel.

[0042] When in use, the elevator button is installed on the elevator button board, and the elevator buttons with the same number as the number of floors are selected according to the actual floors. Passengers press the elevator buttons to make the elevator stop at the corresponding floor and open and close the door.

[0043] See also Figure 1-Figure 4 In this embodiment, the elevator button includes a coaxially arranged housing 1, a character piece 2, a light-distributing piece 3, a transmission piece 4, an elastic reset piece 5, a PCBA board 6 (Printed Circuit Board+Assembly) and a cover plate 7.

[0044] The housing 1 plays a packaging role and is a hollow cylindrical structure with openings at both ends. The cover plate 7 is arranged at one end of the housing 1 to block the opening. The PCBA board 6, the elastic reset member 5, the transmission member 4, the light homogenizing member 3 and the text piece 2 are arranged in the housing in sequence. The PCBA board 6 is arranged adjacent to the cover plate 7.

[0045] The text piece 2 is located at the opening of the housing 1 at one end away from the cover plate 7, and is provided with a number mark to display the corresponding floor.

[0046] See also Figure 5-Figure 7In order to realize the self-balancing function of the elevator button, a first slide groove 11 is provided on the side wall of the housing 1. The first slide groove 11 is arranged at an acute angle with the axis of the housing 1, that is, the extension line of the first slide groove 11 is arranged obliquely relative to the axis of the housing 1, or the extension line of the first slide groove 11 is a thread line. The transmission member 4 is an annular structure adapted to the shape of the housing 1 and is installed in the housing 1. The outer side wall of the transmission member 4 is provided with a first slide post 41 matched with the first slide groove 11. The first slide post 41 can be slidably installed in the first slide groove 11.

[0047] The character piece 2 is installed on the transmission piece 4. When the elevator button is used, the character piece 2 is pressed along the axis of the shell 1, and the character piece 2 moves along the axis direction of the shell 1 and presses the transmission piece 4, so that the transmission piece 4 can move along the axis direction of the shell 1. At the same time, the first slide column 41 can slide from the end of the first slide groove 11 close to the character piece 2 to the end of the first slide groove 11 away from the character piece 2, so that the transmission piece 4 rotates around its own axis while moving along the axis direction of the shell 1, that is, the transmission piece 4 rotates along the thread line, so that the transmission piece 4 drives the character piece 2 to move as a whole, and the character piece 2 will not be pressed on one side and tilted on the other side.

[0048] Specifically, see Figure 4 In this embodiment, the end of the first slide groove 11 close to the character piece 2 is called the first end 111, and the end of the first slide groove 11 away from the character piece 2 is called the second end 112. When the transmission member 4 rotates along the thread line, the first slide post 41 slides from the first end 111 to the second end 112 and then abuts against the second end 112, limiting the movement limit position of the transmission member 4 along the axis of the housing 1.

[0049] In this embodiment, the text piece 2 is bonded to the light homogenizer 3, and the light homogenizer 3 is located in the housing 1 and mounted on the transmission member 4. Specifically, the text piece 2 is bonded to the light homogenizer 3 by double-sided adhesive.

[0050] Specifically, see Figure 6 and Figure 7 The light-distributing member 3 is provided with a second slide post 31, and the side wall of the transmission member 4 is provided with a second slide groove 42 extending in a direction parallel to the end face of the housing 1, that is, the extension line of the second slide groove 42 is perpendicular to the axis of the transmission member 4, and the second slide post 31 can be slidably installed in the second slide groove 42. The second slide post 31 extends along the radial direction of the light-distributing member 3. The second slide groove 42 and the second slide post 31 are arranged so that when the transmission member 4 rotates along the thread line, the light-distributing member 3 only moves along the axis of the housing 1, and does not rotate with the transmission member 4. It is prevented that the numbers on the character piece 2 rotate and become inconvenient to recognize.

[0051] Preferably, in this embodiment, a plurality of second slide posts 31 are evenly spaced along the circumference of the light diffuser 3 , and correspondingly, a plurality of second slide grooves 42 are provided on the side wall of the transmission member 4 , and the second slide posts 31 and the second slide grooves 42 are arranged in one-to-one correspondence.

[0052] Specifically, the transmission member 4 includes an outer ring portion 45, the second slide groove 42 is provided on the outer ring portion 45, and the first slide column 41 is provided on the outer side wall of the outer ring portion 45 and extends in the radial direction of the transmission member 4. Preferably, in this embodiment, a plurality of first slide columns 41 are provided at equal intervals along the circumference of the outer ring portion 45; accordingly, a plurality of first slide grooves 11 are provided on the housing 1, and the first slide grooves 11 are provided in one-to-one correspondence with the first slide columns 41.

[0053] When assembling the elevator button, the letter piece 2 is adhered to the light diffuser 3 , and the second slide post 31 of the light diffuser 3 is installed in the second slide groove 42 , so that the light diffuser 3 is installed on the transmission member 4 .

[0054] Specifically, in this embodiment, the light homogenizer 3 is located inside the outer ring portion 45 and the light homogenizer 3 can rotate around its own axis; preferably, the diameter of the light homogenizer 3 is equal to the inner diameter of the outer ring portion 45, so that the side wall of the light homogenizer 3 abuts against the inner wall of the outer ring portion 45, ensuring the compactness of the installation structure. In order to enable the second slide post 31 of the light homogenizer 3 to be installed in the second slide groove 42, the light homogenizer 3 is provided with a second slide post setting block 32 perpendicular to the light homogenizer 3, and the second slide post 31 is arranged on the second slide post setting block 32. At the same time, the transmission member 4 is provided with a second slide post avoidance groove 44 connected to the second slide groove 42. When the light homogenizer 3 is installed on the transmission member 4, the light homogenizer 3 is superimposed on the transmission member 4 and the second slide post 31 is aligned with the second slide post avoidance groove 44, the light homogenizer 3 is pressed down to make the second slide post 31 slide into the second slide groove 42, and then the light homogenizer 3 is rotated to make the second slide post 31 completely slide into the second slide groove 42.

[0055] Then the assembled text piece 2, light homogenizing piece 3 and transmission piece 4 are installed in the housing 1. For the convenience of introduction, the assembled text piece 2, light homogenizing piece 3 and transmission piece 4 are referred to as the transmission piece as a whole. The opening at one end of the shell 1 where the text piece 2 is located is called the first opening, and the opening at the other end of the shell 1 is called the second opening. When installing the transmission component as a whole, the transmission component as a whole is installed into the shell 1 from the second opening of the shell 1. In order to avoid interference between the first slide post 41 and the inner wall of the shell 1 when installing the transmission component as a whole, an avoidance ring groove 13 is provided in the shell 1 at one end of the second opening. The diameter of the avoidance ring groove 13 is the same as the distance from the end of the first slide post 41 to the center of the transmission component 4. At the same time, a first slide post avoidance groove 14 is also provided on the inner wall of the shell 1. The first slide post avoidance groove 14 extends from the avoidance ring groove 13 to the first slide groove 11. The first slide post 41 is aligned with the first slide post avoidance groove 14, and the transmission component as a whole is pressed so that the first slide post 41 slides from the avoidance ring groove 13 into the first slide post avoidance groove 14 in sequence, and then slides into the second end 112 of the first slide groove 11. The transmission component as a whole is continued to be pressed so that the first slide post 41 slides along the first slide groove 11 to the first end 111. At this point, the transmission component is installed in its entirety in the housing 1 .

[0056] Preferably, in this embodiment, the length of the second slide groove 42 is twice that of the first slide groove 11, and the initial position of the second slide post 31 in the second slide groove 42 is the middle of the second slide groove 42. In this way, when the first slide post 41 slides from the first end 111 to the second end 112, the second slide groove 42 can slide relative to the second slide post 31 during the rotation process until the second slide post 31 abuts against the end of the second slide groove 42.

[0057] When the elevator button is triggered, the operator will remove the pressing force. In order to allow the elevator button to automatically reset, the text piece 2 returns to its initial position. In this embodiment, the elevator button also includes an elastic reset member 5, which is installed in the housing 1 and is located on the side of the transmission member 4 where the text piece 2 is not provided. The elastic reset member 5 is configured to automatically reset the text piece 2 when the pressing force on the text piece 2 is removed.

[0058] See also Figure 4 Specifically, in this embodiment, the elastic restoring member 5 is provided with an elastic protrusion 51 extending toward the light homogenizing member 3 and abutting against the light homogenizing member 3. When the character piece 2 is pressed, the light homogenizing member 3 can compress the elastic protrusion 51, so that the elastic protrusion 51 stores elastic potential energy. In this way, when the pressing force is removed, under the action of the elastic potential energy stored in the elastic protrusion 51, the elastic protrusion 51 applies a restoring force on the light homogenizing member 3 in the opposite direction of the pressing force, so that the light homogenizing member 3 drives the character piece 2 and the transmission member 4 to return to the initial position.

[0059] Preferably, the elastic protrusion 51 is made of silicone.

[0060] Specifically, when the pressing force is removed, under the action of the elastic potential energy stored in the elastic protrusion 51, the light homogenizer 3 is lifted up by the elastic protrusion 51, and the transmission member 4 is lifted up simultaneously with the light homogenizer 3. The first slide post 41 slides along the first slide groove 11 from the second end 112 to the first end 111, and the second slide groove 42 rotates in the opposite direction, so that the second slide post 31 is located in the middle of the second slide groove 42 and returns to its initial position.

[0061] The elastic reset member 5 is mounted on the cover plate 7 and is located in the housing 1. The PCBA board 6 is located between the elastic reset member 5 and the cover plate 7 and is mounted on the cover plate 7. That is, the elastic reset member 5 and the PCBA board 6 are stacked on the cover plate 7.

[0062] In order to position the elastic reset member 5 and the PCBA board 6, a positioning protrusion 72 is provided on the cover plate 7, a first positioning groove 52 cooperating with the positioning protrusion 72 is provided on the elastic reset member 5, and a second positioning groove 62 cooperating with the positioning protrusion 72 is provided on the PCBA board 6. The elastic reset member 5 and the PCBA board 6 are stacked and the first positioning groove 52 and the second positioning groove 62 are aligned. The first positioning groove 52 and the second positioning groove 62 are simultaneously clamped to the positioning protrusion 72 to complete the installation of the elastic reset member 5 and the PCBA board 6 on the cover plate 7.

[0063] See also Figure 4 and Figure 7 A positioning protrusion 61 is provided on the PCBA board 6, and a positioning ring 43 is provided on the transmission member 4 to cooperate with the positioning protrusion 61. The positioning ring 43 is sleeved on the positioning protrusion 61 and can rotate around the axis of the positioning protrusion 61. The arrangement of the positioning protrusion 61 and the positioning ring 43 can make the assembly between the various components of the elevator button more compact.

[0064] Specifically, the axis of the positioning ring 43 coincides with the axis of the transmission member 4. The transmission member 4 is provided with a reinforcing rib 46, one end of the reinforcing rib 46 is connected to the outer ring portion of the transmission member 4, and the other end is connected to the positioning ring 43. Preferably, in this embodiment, a plurality of reinforcing ribs 46 are provided at equal intervals around the axis of the positioning ring 43.

[0065] First, place the PCBA board 6 on the cover plate 7, and position the PCBA board 6 by cooperating between the second positioning groove 62 and the positioning protrusion 72; then, stack the elastic reset member 5 on the PCBA board 6, and position the elastic reset member 5 by cooperating between the first positioning groove 52 and the positioning protrusion 72.

[0066] Preferably, in this embodiment, at least two positioning protrusions 72 are provided along the circumference of the cover plate 7, and accordingly, the elastic return member 5 is provided with a plurality of first positioning grooves 52 corresponding one-to-one to the positioning protrusions 72, and the PCBA board 6 is provided with a plurality of second positioning grooves 62 corresponding one-to-one to the positioning protrusions 72.

[0067] Then the cover plate 7 is installed at the second opening of the housing 1. Specifically, the cover plate 7 is arranged at one end of the housing 1 away from the character piece 2, that is, at the second opening, and is snap-connected with the housing 1.

[0068] Specifically, the cover plate 7 is provided with a hook 71, and the housing 1 is provided with a slot 12 engaged with the hook 71. At the same time, the PCBA board 6 is provided with a hook avoidance slot 63 to prevent the PCBA board 6 from interfering with the hook 71 when it is stacked on the cover plate 7. Figure 8 and Fig. 9 In order to enable the hook 71 to be smoothly engaged in the slot 12, the hook 71 includes an elastic arm 711 and a hook portion 712 provided at the end of the elastic arm 711. Furthermore, a first avoidance notch is provided on the peripheral side of the cover plate 7, and the elastic arm 711 extends from the first avoidance notch perpendicular to the cover plate 7 to prevent the hook 72 from interfering with the inner wall of the housing 1.

[0069] Preferably, a guiding inclined surface 7121 is provided on the hook portion 712. Specifically, the guiding inclined surface is inclined from the end of the elastic arm 711 to the axis close to the cover plate 7.

[0070] The diameter of the elastic reset member 5 is smaller than the diameter of the cover plate 7, so that the elastic arm 711 can abut against the side wall of the elastic reset member 5, which prevents the elastic reset member 5 from interfering with the elastic arm 711 and also makes the elastic reset member 5

[0071] When installing the cover plate 7, the stacked elastic reset member 5, PCBA board 6 and cover plate 7 are placed horizontally, with the cover plate 7 located at the bottom. At this time, the transmission member has been installed in the housing 1 as a whole. The second opening of the housing 1 is moved downward and moved close to the cover plate 7. The upper end of the guide slope 7121 first enters the second opening. As the housing 1 moves downward, the lower end of the guide slope 7121 also enters the housing 1 until the hook portion 712 is completely entered into the housing 1 and the elastic arm 711 is squeezed by the inner wall of the housing 1 to move toward the axial direction of the housing 1. As the housing 1 continues to move downward, when the hook portion 712 is flush with the slot 12, the hook portion 712 is engaged in the slot 12. At this time, the elastic reset member 5 and the PCBA board 6 are clamped in the housing 1, and the assembly of the entire elevator button is completed.

[0072] Preferably, in this embodiment, at least two hooks 71 are evenly spaced along the circumference of the cover plate 7 , and correspondingly, a plurality of slots corresponding to the hooks 71 are formed on the housing 1 .

[0073] After the elevator button provided in this embodiment is pressed, the action process of each component of the elevator button is as follows:

[0074] (1) The operator selects the floor he wants to reach and presses the text piece 2 to activate the elevator button;

[0075] When the character piece 2 is pressed, the pressing force is transmitted from the character piece 2 to the light homogenizer 3 and the transmission piece 4 in sequence. After the transmission piece 4 is subjected to the pressing force, the first slide post 41 slides from the first end 111 to the second end 112 along the extension direction of the first slide groove 11, so that the transmission piece 4 rotates along the thread line along the extension direction of the first slide groove 11, and the transmission piece 4 moves downward as a whole; during the rotation of the transmission piece 4, the second slide groove 42 rotates relative to the second slide post 31, that is, the second slide post 31 only moves along the axial direction of the housing 1, and the second slide groove 42 rotates to prevent the light homogenizer 3 from rotating, so as to prevent the light homogenizer 3 from driving the character piece 2 to rotate, making the number of the floor displayed on the character piece 2 inconvenient to recognize; during the pressing process, the elastic protrusion 51 on the elastic reset piece 5 is compressed;

[0076] (2) The operator completes floor selection and releases the pressing force;

[0077] After the pressing force is removed, the compressed elastic protrusion 51 will return to its original state, and will apply a force on the light homogenizer 3 in the opposite direction to the pressing force. Under the action of this force, the light homogenizer 3 drives the text piece 2 and the transmission member 4 to move toward the first opening. At the same time, the first slide column 41 slides from the second end 112 along the first slide groove 11 to the first end 111. At this time, the light homogenizer 3 will no longer move toward the first opening, and the elevator button is reset, waiting for the next operation.

[0078] The elevator button provided in this embodiment is easy to assemble and has a self-balancing function. The situation where one side is pressed and the other side is not lifted will not occur, and the pressing feel is good.

[0079] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
