Description

Technical Field

[0001] The present invention relates to the field of electronic devices, and in particular to an electronic device and an installation method thereof. Background Art

[0002] When installing electronic devices on the surface of some equipment, the installation is inconvenient. For example, in an existing elevator panel, if you need to add products such as card readers and elevator control products to the existing panel, you need to cut a square groove or special-shaped groove on the elevator control panel in advance to fit the product installation, and then fix the product on the elevator by screws, buckles, etc. The installation steps are relatively cumbersome, and the subsequent function upgrade of the delivered elevator is difficult to install and operate. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an electronic device and an installation method thereof, which adopts a threaded locking solution and can adapt to installation requirements under various sheet metals of different thicknesses, and is particularly suitable for the transformation and upgrading of existing products.

[0004] In one embodiment of the present invention, an electronic device is provided, which is mounted on a planar carrier and includes:

[0005] A body, the body is formed in a cylindrical shape and has a central axis perpendicular to the plane carrier, and a first end portion of the body has an operation panel with a diameter larger than that of the body;

[0006] A locking ring, wherein the locking ring is threadedly matched with a peripheral wall of the body, and the locking ring is coaxial with the body so as to rotate relative to the body around the central axis to adjust the axial distance between the locking ring and the operating panel; and

[0007] a stop mechanism, the stop mechanism being mounted on the body and interfering with the locking ring when the locking ring is threadedly engaged with the body, so as to limit the relative position of the body and the locking ring in the rotation direction around the central axis;

[0008] The planar carrier is provided with an opening adapted to the cross-sectional shape of the main body, and the main body is inserted into the opening so that the operating panel abuts against the planar carrier from the outside, and the locking ring abuts against the planar carrier from the inside, and the axial spacing between the locking ring and the operating panel corresponds to the thickness of the planar carrier.

[0009] In one embodiment, the stop mechanism is configured to limit the relative position of the body and the locking ring in a first direction of rotation around the central axis.

[0010] The first direction corresponds to the direction in which the axial spacing increases.

[0011] In one embodiment, the locking ring comprises:

[0012] an annular side wall, the inner surface of which is threadably engaged with the peripheral wall of the body; and

[0013] A latching tooth, the latching tooth extending radially inward from a side of the annular side wall away from the body;

[0014] Wherein, the stop mechanism cooperates with the latching teeth in a limiting manner.

[0015] In one embodiment, the stop mechanism is a claw protruding from the second end of the body, and the claw is limitedly matched with the tooth.

[0016] In one embodiment, the claw is elastically connected to the second end portion so as to adjust the spacing with the latch tooth in the axial direction in response to an external force, thereby engaging with the latch tooth in a limiting manner or unlocking the limiting engagement.

[0017] In one embodiment, the latch tooth has a first tooth surface extending in a radial direction and a second tooth surface forming a first angle with the radial direction.

[0018] The second tooth surface guides the stop mechanism in a second direction opposite to the first direction.

[0019] In one embodiment, the thickness of the claw at the central axis is greater than or equal to the thread length.

[0020] In one embodiment, the side of the operating panel facing the planar carrier has an adhesive bonded to the planar carrier.

[0021] Another embodiment of the present invention further provides a method for installing the electronic device as described above, comprising:

[0022] The planar carrier is provided with an opening adapted to the cross-sectional shape of the body;

[0023] The body is inserted into the opening until the operation panel abuts against the plane carrier from the outside;

[0024] The locking ring is threadably engaged with the body from the inner side of the planar carrier until the locking ring abuts against the planar carrier from the inner side;

[0025] When the locking ring is threadedly engaged with the body, the stop mechanism interferes with the locking ring to limit the relative position of the body and the locking ring in the rotation direction around the central axis.

[0026] In one embodiment, the operating panel is bonded to the planar carrier via an adhesive.

[0027] As described above, by adopting a rotatable cylindrical shape and a threaded connection method with adjustable mating spacing, the fixing method of the electronic device in this example can be adapted to planar carriers 1 of different thicknesses. And since it is not necessary to use fasteners beyond the cross-sectional shape range of the body 10 for fixed connection, the requirements for the size of the opening on the planar carrier 1, the installation and fixing method of the electronic device, and the operating space of the planar carrier 1 are all very low.

[0028] Furthermore, in view of the fact that the threaded fit is fixed by friction, the electronic device of this example further includes a stop mechanism 30, wherein the stop mechanism 30 is installed on the body 10 and interferes with the locking ring 20, and is used to limit the relative position of the body 10 and the locking ring 20 in the rotation direction around the central axis L. When the locking ring 20 rotates to a position where the operation panel 11 can abut against the plane carrier 1 from the outside and the locking ring 20 abuts against the plane carrier 1 from the inside, the locking ring 20 and the body 10 clamp the plane carrier 1 in the middle, and the stop mechanism 30 limits the relative rotation of the locking ring 20 and the body 10, so as to prevent the locking ring and the body from rotating relative to each other due to external forces such as vibration, causing the electronic device to fall off from the plane carrier.

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0039] like Figure 1 to Figure 2b As shown, an embodiment of the present invention provides an electronic device, mounted on a plane carrier 1, comprising:

[0040] The body 10 is formed in a cylindrical shape and has a central axis L perpendicular to the plane carrier 1. The first end of the body 10 has an operation panel 11 with a diameter larger than that of the body 10;

[0041] A locking ring 20, the locking ring 20 is threadedly matched with the peripheral wall of the body 10, and the locking ring 20 is coaxial with the body 10, so as to rotate relative to the body 10 around the central axis L, thereby adjusting the axial distance between the locking ring 20 and the operation panel 11; and

[0042] A stop mechanism 30, which is mounted on the body 10 and interferes with the locking ring 20 when the locking ring 20 and the body 10 are threadedly engaged, so as to limit the relative position of the body 10 and the locking ring 20 in the rotation direction around the central axis L;

[0043] Among them, the plane carrier 1 is provided with an opening 2 adapted to the cross-sectional shape of the main body 10, and the main body 10 is inserted into the opening 2 so that the operation panel 11 abuts against the plane carrier 1 from the outside, and the locking ring 20 abuts against the plane carrier 1 from the inside, and the axial distance between the locking ring 20 and the operation panel 11 corresponds to the thickness of the plane carrier 1.

[0044] This example can be applied to the replacement of elevator operating panels, for example, the electronic device can be a data reading device such as a card reader, and the plane carrier 1 can be a surface to be installed on the elevator operating panel. The electronic device is installed on the plane carrier 1, and the plane carrier 1 only needs to have an opening 2 adapted to the body 10 of the electronic device.

[0045] The body 10 of the electronic device is formed as a cylinder that can rotate around the central axis L. The body 10 is installed on one side of the outer surface of the plane carrier 1 and is threadedly matched with the locking ring 20. The locking ring 20 is located on one side of the inner surface of the plane carrier 1. The locking ring 20 is threadedly matched with the outer wall of the body 10. The number of thread teeth of the contacting match is adjusted by rotating around the central axis L, thereby adjusting the axial distance between the locking ring 20 and the end of the body 10.

[0046] The body 10 and the locking ring 20 are respectively located on the inner and outer sides of the planar carrier 1 to clamp the planar carrier 1 in the middle. The body 10 has a first diameter, and one end thereof in the direction of the central axis L has an operation panel 11 with a diameter larger than that of the body 10. The diameter of the opening 2 is adapted to the first diameter of the body 10 and is smaller than the diameter of the operation panel 11. When the body 10 is inserted into the opening 2, the operation panel 11 can abut against the planar carrier 1 from the outside, and by tightening the locking ring 20, the locking ring 20 can abut against the planar carrier 1 from the inside.

[0047] It can be seen that by adopting a rotatable cylindrical shape and a threaded connection method with adjustable mating spacing, the fixing method of the electronic device in this example can be adapted to planar carriers 1 of different thicknesses. And because it is not necessary to use fasteners beyond the cross-sectional shape range of the body 10 for fixed connection, the requirements for the size of the opening on the planar carrier 1, the installation and fixing method of the electronic device, and the operating space of the planar carrier 1 are all very low.

[0048] Furthermore, in view of the fact that the threaded fit is fixed by friction, the electronic device of this example further includes a stop mechanism 30, wherein the stop mechanism 30 is installed on the body 10 and interferes with the locking ring 20, and is used to limit the relative position of the body 10 and the locking ring 20 in the rotation direction around the central axis L. When the locking ring 20 rotates to a position where the operation panel 11 can abut against the plane carrier 1 from the outside and the locking ring 20 abuts against the plane carrier 1 from the inside, the locking ring 20 and the body 10 clamp the plane carrier 1 in the middle, and the stop mechanism 30 limits the relative rotation of the locking ring 20 and the body 10, so as to prevent the locking ring and the body from rotating relative to each other due to external forces such as vibration, causing the electronic device to fall off from the plane carrier.

[0049] In a specific example, the stop mechanism 30 is configured to limit the relative position of the body 10 and the locking ring 20 in a first direction rotating around the central axis L, wherein the first direction corresponds to a direction in which the axial spacing increases.

[0050] The stop mechanism 30 is unidirectionally limited in the rotation direction, specifically, in the direction of preventing the locking ring and the body from falling off. The first direction corresponds to the direction in which the axial distance between the first end of the body 10 and the locking ring 20 is increased.

[0051] When the locking ring 20 rotates relative to the body 10 to lock with the body 10 and rotates in a direction that reduces the axial distance between the first end of the body 10 and the locking ring 20, the stop mechanism 30 will not prevent the rotation in this direction. In the first direction opposite to the first direction, that is, in a direction that increases the axial distance between the first end of the body 10 and the locking ring 20, the locking ring 20 is prevented from rotating, thereby preventing the installed electronic device from falling off the planar carrier.

[0052] In a specific example, Figure 2a and Figure 2b As shown, the locking ring 20 comprises:

[0053] An annular side wall 21, the inner surface of which is threadedly engaged with the peripheral wall of the body 10; and

[0054] A latching tooth 22 extending radially inward from a side of the annular side wall 21 away from the body 10;

[0055] The stop mechanism 30 is in position-limiting cooperation with the latching teeth 22 .

[0056] The locking ring 20 is formed into a structure similar to a hollow bottle cap, the annular side wall 21 is used for threaded cooperation with the body 10, and the latch 22 is arranged on the side of the annular side wall 21 away from the body 10. The latch 22 extends radially inward from the edge of the annular side wall 21. The stop mechanism 30 protrudes from the body 10 in the direction of the central axis L, and can be limitedly cooperated with the latch 22, so as to realize the locking of the stop mechanism 30 and the locking ring 20 in the rotation direction.

[0057] Specifically, the stop mechanism 30 is a claw protruding from the second end of the body 10, and the claw is limitedly matched with the latch tooth 22. The stop mechanism 30 includes a support rod and a claw located at the end of the support rod, wherein the support rod is connected to the body 10 and forms an angle with the second end of the body 10. The claw is adapted to the latch tooth 22 and forms a surface contact with the latch tooth 22.

[0058] Preferably, the stop mechanism 30 is elastically connected to the second end portion so as to adjust the distance with the latch tooth 22 in the axial direction in response to an external force, thereby performing limiting cooperation or unlocking limiting cooperation with the latch tooth 22 .

[0059] Specifically, one end of the support rod is elastically connected to the second end, and the other end has a claw. One end of the support rod is connected to the second end via an elastic element. When the elastic element is in a free state, the support rod forms an angle with the second end of the body 10, and the claw forms a surface contact with the latch 22. The stop mechanism 30 is pushed by an external force, so that the claw moves toward the direction close to the second end to disengage from the contact position of the limit fit with the latch 22, thereby unlocking the limit fit with the latch 22.

[0060] The second end portion may have, for example, a groove for accommodating the stop mechanism 30 , so that the stop mechanism 30 can be pressed to a position flush with the second end portion, thereby ensuring that the stop mechanism 30 can be released from the contact position of the limiting engagement with the latch tooth 22 .

[0061] When the body 10 and the locking ring 20 clamp the planar carrier 1 therebetween, the minimum spacing between the second end of the body 10 and the locking ring 20 can be as low as zero, that is, the second end is flush with the surface where the latch teeth 22 are located. The spacing can also be greater than zero, which corresponds to the thickness of the planar carrier 1 in the direction of the central axis L.

[0062] It can be understood that the distance between the second end of the main body 10 and the locking ring 20 should correspond to the distance between the claw of the stop mechanism 30 and the second end, and the distance between the claw of the stop mechanism 30 and the second end can be achieved by adjusting the length of the free position of the elastic element.

[0063] like Figure 2a and Figure 2b As shown, the latch tooth 22 has a first tooth surface 221 extending in the radial direction and a second tooth surface 222 forming a first angle with the radial direction.

[0064] The second tooth surface 222 guides the stop mechanism 30 in a second direction opposite to the first direction.

[0065] The latching tooth 22 has a vertical tooth surface, namely a first tooth surface 221, and an inclined tooth surface, namely a second tooth surface 222, wherein the first tooth surface extends in the radial direction, and the second tooth surface 222 forms a first angle with the radial direction. When the latching claw of the stop mechanism 30 cooperates with the latching tooth 22, the second tooth surface 222 is used to guide the movement of the latching claw in a direction conducive to rotation, while the first tooth surface 221 is used to limit the rotation in a direction opposite to the rotation direction.

[0066] According to the characteristics of the one-way limiting stop mechanism 30 in this example, the rotation direction should be a second direction opposite to the first direction. The second tooth surface 222 is used to guide the claw in the second direction, that is, when the locking ring 20 rotates in a direction (second direction) that reduces the distance between the first end of the body 10 and the locking ring 20, the claw can slide along the second tooth surface 222 until it slides to the next second tooth surface 222. The process of switching the claw from one second tooth surface 222 to the next second tooth surface 222 is achieved by the elastic deformation of the stop mechanism 30. During the rotation along the second direction, the stop mechanism 30 will not limit the locking ring 20. When the locking ring 20 rotates in a direction (first direction) that increases the distance between the first end of the body 10 and the locking ring 20, the claw will interfere with the first tooth surface 221 between two adjacent second tooth surfaces 222, and the first tooth surface 221 will completely block the claw in the rotation direction of the first direction, so that it cannot avoid the first tooth surface 221 by elastic deformation, thereby preventing the locking ring 20 from rotating along the first direction, thereby achieving the purpose of stop locking.

[0067] In a preferred example, the thickness of the claw in the direction of the central axis L is greater than or equal to the thread length. The thread length is the length in the direction of the central axis L, representing the maximum thickness of the planar carrier 1 that the electronic device of this example can be applied to. Any planar carrier 1 with a thickness less than the thread length can be applied to the electronic device of this example.

[0068] When the thickness of the claw in the direction of the central axis L is greater than or equal to the thread length, it is possible to ensure that the claw can be clamped on the clamping teeth 22 when applied to a planar carrier 1 of any thickness without adjusting the elastic element of the stop mechanism 30 .

[0069] In one embodiment, the side of the operating panel 11 facing the planar carrier 1 has an adhesive 12 which is bonded to the planar carrier 1 .

[0070] Thus, the body 10 can be fixed to the plane carrier 1 via the adhesive 12, and the operator can install the electronic device by rotating the locking ring 20 without holding the body 10. This can prevent the body 10 from falling and simplify the installation process of the electronic device.

[0071] An embodiment of the present invention further provides a method for installing the electronic device as described above, comprising:

[0072] The plane carrier 1 is provided with an opening 2 adapted to the cross-sectional shape of the body 10;

[0073] The body 10 is inserted into the opening 2 until the operation panel 11 abuts against the flat carrier 1 from the outside;

[0074] The locking ring 20 is threadably engaged with the body 10 from the inner side of the planar carrier 1 until the locking ring 20 abuts against the planar carrier 1 from the inner side;

[0075] When the locking ring 20 and the body 10 are threadedly engaged, the stop mechanism 30 interferes with the locking ring 20 to limit the relative positions of the body 10 and the locking ring 20 in the rotation direction around the central axis L.

[0076] Specifically, the operating panel 11 is bonded to the planar carrier 1 via an adhesive.

[0077] Based on the above installation method, the disassembly process of the electronic device in this example includes: pressing the stop mechanism 30 so that the stop mechanism 30 is offset from the locking ring 20 to release the locking of the stop mechanism 30. Then, the locking ring 20 is rotated along the first direction to quickly disassemble the electronic device.

[0078] As mentioned above, since the equipment needs to adapt to walls of different thicknesses, the snap-on structure cannot cope with vibration scenarios and is prone to shaking and detaching after long-term use. This structure adopts a threaded locking solution, which can adapt to the installation requirements of various sheet metals of different thicknesses, making it convenient for workers to install quickly. In addition, the product fastening adopts a one-way ratchet stop structure. When the whole machine is installed, the locking ring is tightened clockwise, and the stop buckle and the card slot on the locking ring are staggered to avoid each other. When the installation is tight, the stop buckle and the locking ring card slot are stuck in the opposite direction to prevent loosening. When disassembling the whole machine, you only need to press the stop buckle to quickly disassemble it.

[0079] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention, such as combination, division or repetition of features, should be included in the scope of protection of the present invention.
