Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to an electronic device. Background Technology

[0002] Increasingly, electronic devices in related technologies have a stand on the side facing away from the display to support their placement on a desktop. However, the stand in these devices is usually connected to the main body via a separate pivot, and includes components such as a damping sleeve and a shaft end cap to limit the damping sleeve. This results in a large number of parts and a complex assembly process. Utility Model Content

[0003] The main objective of this application is to provide an electronic device that reduces the number of components to simplify the assembly process.

[0004] To achieve the above objectives, the electronic device proposed in this application includes a body, a bracket, and a limiting structure. The body has one of a rotating shaft and a shaft hole; the bracket has the other of a rotating shaft and a shaft hole, with the rotating shaft inserted into the shaft hole to allow the bracket to have a folded state that fits against the body and an unfolded state that is angled towards the body. The limiting structure includes an elastic arm and a limiting protrusion assembly, one of which is located in the body and the other in the bracket. The limiting protrusion assembly includes a first limiting protrusion and a second limiting protrusion spaced apart. In the folded state, the elastic arm abuts against the side of the first limiting protrusion away from the second limiting protrusion to prevent the bracket from rotating to the unfolded state. In the unfolded state, the elastic arm is engaged between the first limiting protrusion and the second limiting protrusion.

[0005] Optionally, the elastic arm extends along a first direction, and a rotating shaft or shaft hole is provided in the elastic arm, with the rotating shaft extending along a second direction intersecting the first direction.

[0006] Optionally, at least one of the elastic arm and the first limiting protrusion is provided with a first guide surface, which is configured to guide the elastic arm to deform along a second direction so that the elastic arm can rotate to engage between the first limiting protrusion and the second limiting protrusion; at least one of the elastic arm and the first limiting protrusion is also provided with a second guide surface, which is configured to guide the elastic arm to deform along a second direction so that the elastic arm can rotate out of the first limiting protrusion and the second limiting protrusion.

[0007] Optionally, the support includes a first plate and a second plate connected to each other. The first plate and the second plate are arranged in a first direction, and in a second direction, the projected size of the second plate is smaller than the projected size of the first plate. An elastic arm is provided at one end of the first plate connected to the second plate, and forms a deformation gap with the second plate.

[0008] Optionally, the rotating shaft or shaft hole is located on the side of the elastic arm opposite to the deformation gap, and at the end of the elastic arm away from the connection to the first plate.

[0009] Optionally, the elastic arm has a first abutting surface and a second abutting surface arranged opposite to each other, a first limiting protrusion has a first limiting surface and a second limiting surface arranged opposite to each other, a second limiting protrusion has a third limiting surface, and the first limiting surface is arranged away from the third limiting surface relative to the second limiting surface; in the folded state, the second abutting surface abuts against the first limiting surface; in the unfolded state, the first abutting surface abuts against the second limiting surface, and the second abutting surface abuts against the third limiting surface.

[0010] Optionally, the first limiting protrusion also has a first connecting surface, which connects the first limiting surface and the second limiting surface and is disposed toward the side where the rotating shaft is located; the first abutting surface is recessed to form a recessed groove, and in the unfolded state, the connection between the second limiting surface and the first connecting surface is accommodated in the recessed groove.

[0011] Optionally, the body has a display surface and a back-to-back surface facing each other, with a storage groove on the back-to-back surface; the shaft hole and the limiting protrusion are both located on the groove wall of the storage groove, and the rotating shaft and the elastic arm are both located on the bracket; in the folded state, the bracket is housed in the storage groove.

[0012] Optionally, the storage slot includes a first slot and a second slot, the second slot is disposed on the bottom wall of the first slot, and the limiting protrusion is disposed on the slot wall of the second slot; in the folded state, the bracket is housed in the first slot, and the pivot is located on the side of the second limiting protrusion opposite to the bottom wall of the second slot, and the end of the elastic arm that is rotatably connected to the bracket is located on the side of the first limiting protrusion opposite to the bottom wall of the second slot.

[0013] Optionally, the electronic device is a doorbell indoor unit.

[0014] The electronic device of this application achieves a direct rotatable connection between the body and the bracket by directly providing a rotating shaft in one of them and a shaft hole in the other. This eliminates the need for a separate rotating shaft for through-hole connection. Furthermore, the electronic device in this solution further includes an elastic arm in one of the body and the bracket, and a limiting protrusion assembly including a first limiting protrusion and a second limiting protrusion in the other. In the folded state, the elastic arm abuts against the side of the first limiting protrusion away from the second limiting protrusion, preventing the bracket from rotating to the unfolded state, thus limiting the bracket in the folded state. In the unfolded state, the elastic arm's deformability allows it to engage between the first and second limiting protrusions, further limiting the bracket in the unfolded state. Since the elastic arm and the limiting protrusion assembly are also directly provided in the body and the bracket, there is no need for separate damping sleeves or shaft end caps to provide limiting damping force to the bracket. In other words, the electronic device in this solution can achieve a stable folded and unfolded state of the support through two structural components: the body and the bracket. This reduces the number of parts in the electronic device and simplifies the assembly process. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0035] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0036] This application proposes an electronic device, which can be a doorbell indoor unit or a tablet computer, as long as it has a rotatable bracket on the side facing away from the display surface so that the electronic device can be easily placed on a table or other support surface after the bracket is unfolded. This application does not limit the type of electronic device.

[0037] Please refer to the reference. Figures 1 to 7In one embodiment of this application, the electronic device 100 may include a body 10, a bracket 20, and a limiting structure 30. The body 10 is provided with one of a rotating shaft 311 and a shaft hole 13; the bracket 20 is provided with the other of a rotating shaft 311 and a shaft hole 13, with the rotating shaft 311 inserted into the shaft hole 13, so that the bracket 20 has a folded state that fits against the body 10 and an unfolded state that is angled toward the body 10; the limiting structure 30 includes an elastic arm 31 and a limiting protrusion group 33, with one of the elastic arm 31 and the limiting protrusion group 33 provided in the body 10 and the other in the bracket 20, and the limiting protrusion group 33 includes a first limiting protrusion 331 and a second limiting protrusion 332 that are spaced apart; in the folded state, as Figure 2 , Figure 4 as well as Figure 5 As shown, the elastic arm 31 abuts against the side of the first limiting protrusion 331 away from the second limiting protrusion 332 to prevent the bracket 20 from rotating to the unfolded state; in the unfolded state, as Figure 3 , Figure 6 as well as Figure 7 As shown, the elastic arm 31 is engaged between the first limiting protrusion 331 and the second limiting protrusion 332.

[0038] The body 10 serves as the main structure of the electronic device 100, enabling it to perform basic functions. The body 10 may include a casing, a display screen, and a control board. The display screen can be embedded in the casing and has an exposed display surface 11 for displaying image information, etc. The control board can be housed within the casing and electrically connected to the display screen for controlling its operation. When the electronic device 100 is a doorbell indoor unit, the body 10 may also include an antenna for information interaction with the doorbell outdoor unit. After the doorbell outdoor unit acquires visitor information via a camera, it can transmit the visitor's image information to the doorbell indoor unit, allowing indoor occupants to observe the visitor. Since the working principles of the doorbell indoor and outdoor units are existing technologies, their specific structures are not detailed here. Furthermore, the body 10 can be rectangular, square, or circular on the projection surface perpendicular to the display surface 11; this application does not limit the shape of the body 10.

[0039] The bracket 20 can be rotatably mounted on the body 10 via the cooperation of the pivot 311 and the shaft hole 13. The housing of the body 10 may have a back-side face 12 facing away from the display surface 11. The bracket 20 can be installed on the side of this back-side face 12 to reduce the overall size of the electronic device 100 and minimize its appearance. However, this application is not limited to this; in some embodiments, the bracket 20 may also be installed on the side wall of the body 10 located between the display surface 11 and the back-side face 12. Alternatively, the pivot 311 can be mounted on the bracket 20, and the shaft hole 13 can be located on the body 10. Of course, the pivot 311 can also be mounted on the body 10, and the shaft hole 13 can be located on the bracket 20, ensuring that the bracket 20 can be rotatably mounted on the body 10 and has both a folded and unfolded state. In the unfolded state, the bracket 20 and the body 10 can form an angle, allowing the electronic device 100 to be placed on a support surface such as a desktop with the display surface 11 tilted upwards. Furthermore, the support 20 can be a plate structure, making its structure simpler and providing higher structural strength to improve its supporting effect. Of course, this application is not limited to this; in some embodiments, the support 20 can also be a U-shaped rod structure, with the two ends of the opening formed by the U-shaped rod being rotatably connected.

[0040] The limiting structure 30, through the first limiting protrusion 331 and the second limiting protrusion 332 in the limiting protrusion group 33, can provide corresponding limiting functions for the elastic arm 31 in different states of the bracket 20. The elastic arm 31 allows the bracket 20 to elastically deform and move to different positions for limiting when rotating and switching states, so that the bracket 20 can be held in the corresponding state. That is, in the folded state, the elastic arm 31 abuts against the side of the first limiting protrusion 331 away from the second limiting protrusion 332, preventing the bracket 20 from rotating outward and unfolding when not subjected to external force. When the bracket 20 is needed to prop the electronic device 100 at an angle on a table or other support surface, the bracket 20 can be manually driven to rotate outward. This causes the elastic arm 31 to elastically deform and move past the first limiting protrusion 331 to engage between the first limiting protrusion 331 and the second limiting protrusion 332. This allows the bracket 20 to remain in its extended state when not subjected to external force, thanks to the limiting protrusions 331 and 332. Alternatively, the elastic arm 31 can be mounted on the bracket 20, and the limiting protrusion group 33 can be mounted on the body 10. Of course, the elastic arm 31 can also be mounted on the body 10, and the limiting protrusion group 33 can be mounted on the bracket 20.

[0041] When the elastic arm 31 is mounted on the bracket 20, and the limiting protrusion 33 is mounted on the body 10, with one end of the elastic arm 31 abutting against the limiting protrusion 33 and the bracket 20 rotatably connected to the body 10, respectively located on opposite sides of the axis of the rotating shaft 311, in the folded state, the inner side of the elastic arm 31 abuts against the outer side of the first limiting protrusion 331, where both the inner and outer sides are defined with reference to the center of the body 10. Alternatively, when the end of the elastic arm 31 abuts against the limiting protrusion 33 and the bracket 20 rotatably connected to the body 10, located on the same side of the axis of the rotating shaft 311, in the folded state, the outer side of the elastic arm 31 abuts against the inner side of the first limiting protrusion 331.

[0042] When the elastic arm 31 is mounted on the body 10, and the limiting protrusion 33 is mounted on the bracket 20, with the limiting protrusion 33 and the bracket 20 rotatably connected to one end of the body 10 and located on opposite sides of the axis of the rotating shaft 311, in the folded state, the outer side of the elastic arm 31 abuts against the inner side of the first limiting protrusion 331. Alternatively, when the limiting protrusion 33 and the bracket 20 are rotatably connected to one end of the body 10 and located on the same side of the axis of the rotating shaft 311, in the folded state, the inner side of the elastic arm 31 abuts against the outer side of the first limiting protrusion 331.

[0043] Furthermore, when the elastic arm 31 is mounted on the bracket 20, the rotating shaft 311 or the shaft hole 13 can be set independently of the elastic arm 31, or it can be directly mounted on the elastic arm 31 as described below. Additionally, during rotation, the elastic arm 31 can deform along its extension direction, or it can deform along a direction intersecting the extension direction of the elastic arm 31 as described below. Furthermore, to improve the stability of the bracket 20 mounted on the body 10, the bracket 20 can be rotatably connected at both ends of the rotating shaft 311 via the cooperation of the rotating shaft 311 and the shaft hole 13. Similarly, two limiting structures 30 can be provided, distributed at both ends of the rotating shaft 311 along its axial direction.

[0044] The electronic device 100 of this application achieves a direct rotatable connection between the body 10 and the bracket 20 by directly providing a rotating shaft 311 in one of them and a shaft hole 13 in the other. This eliminates the need for a separate rotating shaft 311 for through-hole connection. Furthermore, the electronic device 100 further provides an elastic arm 31 in one of the body 10 and the bracket 20, and a limiting protrusion group 33 including a first limiting protrusion 331 and a second limiting protrusion 332. In the folded state, the elastic arm 31 abuts against the side of the first limiting protrusion 331 away from the second limiting protrusion 332, preventing the bracket 20 from rotating to the unfolded state, thus limiting the bracket 20 in the folded state. In the unfolded state, the deformable elastic arm 31 can engage between the first limiting protrusion 331 and the second limiting protrusion 332, further limiting the bracket 20 in the unfolded state. At this point, since the elastic arm 31 and the limiting protrusion 33 are also directly mounted on the body 10 and the bracket 20, there is no need to additionally set up independent damping sleeves and shaft end caps to limit the damping sleeves to provide limiting damping force to the bracket 20. That is, in this solution, the electronic device 100 can achieve a stable folded state and unfolded state of the bracket 20 through the two structural components of the body 10 and the bracket 20, thereby reducing the number of parts of the electronic device 100 and simplifying the assembly process of the electronic device 100.

[0045] Please refer to the reference. Figure 4 , Figure 5 , Figure 8 as well as Figure 9 In one embodiment of this application, the elastic arm 31 extends along a first direction, and the rotating shaft 311 or the shaft hole 13 is disposed in the elastic arm 31. The rotating shaft 311 extends along a second direction intersecting the first direction.

[0046] When the bracket 20 is in the unfolded state and the electronic device 100 is placed normally on a support surface such as a desktop, the first direction can be the tilt direction and the second direction can be the horizontal direction.

[0047] In this embodiment, the rotating shaft 311 or the shaft hole 13 is directly set on the elastic arm 31, so that when the bracket 20 is rotated and installed on the body 10, the rotating shaft 311 can be inserted into the shaft hole 13 by driving the elastic arm 31 to deform, which further improves the convenience of assembling the electronic device 100.

[0048] Please refer to the reference. Figures 4 to 13In one embodiment of this application, the elastic arm 31 has a first abutting surface 312 and abutting surface 313 disposed opposite to each other, a first limiting protrusion 331 has a first limiting surface 3311 and a second limiting surface 3312 disposed opposite to each other, a second limiting protrusion 332 has a third limiting surface 3321, and the first limiting surface 3311 is disposed further away from the third limiting surface 3321 than the second limiting surface 3312; in the folded state, the second abutting surface 313 abuts against the first limiting surface 3311; in the unfolded state, the first abutting surface 312 abuts against the second limiting surface 3312, and the second abutting surface 313 abuts against the third limiting surface 3321.

[0049] In this embodiment, when the bracket 20 is in the folded state, the elastic arm 31 and the first limiting protrusion 331 are configured to engage through surface contact via the second abutment surface 313 and the first limiting surface 3311; when the bracket 20 is in the unfolded state, the elastic arm 31 and the first limiting protrusion 331 and the second limiting protrusion 332 are configured to engage through surface contact via the first abutment surface 312 abutting against the second limiting surface 3312, and the second abutment surface 313 abutting against the third limiting surface 3321. This increases the contact area between the elastic arm 31 and the limiting protrusion assembly 33 in different states, thereby improving the stability of the bracket 20 in both the folded and unfolded states. Of course, this application is not limited to this; in other embodiments, the first limiting protrusion 331 and the second limiting protrusion 332 can be spherical, allowing the elastic arm 31 to engage in point contact with the first limiting protrusion 331 and the second limiting protrusion 332.

[0050] Please refer to the reference. Figures 4 to 7 In one embodiment of this application, the first limiting protrusion 331 further has a first connecting surface 3313, which connects the first limiting surface 3311 and the second limiting surface 3312 and is disposed on one side facing the rotating shaft 311; the first abutting surface 312 is recessed to form a recessed groove 3121, and in the unfolded state, the connection between the second limiting surface 3312 and the first connecting surface 3313 is accommodated in the recessed groove 3121.

[0051] In this embodiment, when the bracket 20 is in the unfolded state, the connection between the second limiting surface 3312 of the first limiting protrusion 331 and the first connecting surface 3313 is accommodated in the recessed groove 3121, which facilitates increasing the contact area between the elastic arm 31 and the first limiting protrusion 331, so that the two can be stably engaged. Moreover, at this time, the second abutment surface 313, the first limiting surface 3311, and the second limiting surface 3312 can all be set as planes, and the first limiting surface 3311 and the second limiting surface 3312 can be set in parallel, so that the structure of the first limiting protrusion 331 can be relatively simple. The second limiting surface 3312 can also be a plane, and is set at an acute angle to the plane where the first limiting surface 3311 or the second limiting surface 3312 is located, so as to fit and abut against the second abutment surface 313, while simplifying the structure of the second limiting protrusion 332.

[0052] Please refer to the reference. Figures 8 to 13 In one embodiment of this application, at least one of the elastic arm 31 and the first limiting protrusion 331 is provided with a first guide surface 34. The first guide surface 34 is configured to guide the elastic arm 31 to deform along a second direction so that the elastic arm 31 can rotate to engage between the first limiting protrusion 331 and the second limiting protrusion 332. At least one of the elastic arm 31 and the first limiting protrusion 331 is also provided with a second guide surface 35. The second guide surface 35 is configured to guide the elastic arm 31 to deform along a second direction so that the elastic arm 31 can rotate out of the first limiting protrusion 331 and the second limiting protrusion 332.

[0053] In this embodiment, the elastic arm 31 is guided to deform along the second direction during rotation by the first guide surface 34 or the second guide surface 35. The elastic arm 31 has a greater deformation capacity in the second direction, thus facilitating deformation of the elastic arm 31 as it follows the rotation of the bracket 20, thereby switching the state of the bracket 20. The elastic arm 31 may also have a second connecting surface 314 connecting the first abutment surface 312 and the second abutment surface 313, which intersects the axis of the rotating shaft 311. The first limiting protrusion 331 may also have a third connecting surface 3314 connecting the first limiting surface 3311, the second limiting surface 3312, and the first connecting surface 3313. In this case, the first guide surface 34 may be provided at least one of the connections between the first abutment surface 312 and the second connecting surface 314, or at the connection between the first limiting surface 3311 and the third connecting surface 3314. At least one of the following locations is provided: the connection between the second abutment surface 313 and the second connecting surface 314, and the connection between the second limiting surface 3312 and the third connecting surface 3314. Additionally, the first guiding surface 34 can be a rounded corner structure, or it can be a beveled corner structure. Furthermore, it should be noted that the deformation distance of the elastic arm 31 along the second direction during the rotation of the bracket 20 needs to be less than the distance the rotating shaft 311 is inserted into the shaft hole 13, to prevent the elastic arm 31 from disengaging from the rotating shaft 311 and the shaft hole 13 during deformation.

[0054] Please refer to the reference. Figure 8 and Figure 9 In one embodiment of this application, the bracket 20 includes a first plate 21 and a second plate 22 connected to each other. The first plate 21 and the second plate 22 are arranged in a first direction, and in a second direction, the projected size of the second plate 22 is smaller than the projected size of the first plate 21. An elastic arm 31 is provided at one end of the first plate 21 connected to the second plate 22, and forms a deformation gap 315 between the first plate 21 and the second plate 22.

[0055] In this embodiment, the elastic arm 31 and the second plate 22 are arranged side by side with intervals, which can achieve a compact arrangement of the two, reduce the overall volume of the bracket 20, and improve the convenience of its installation on the body 10. The deformation gap 315 can facilitate the deformation of the elastic arm 31 along the second direction during the process of the bracket 20. Of course, this application is not limited to this. In other embodiments, the bracket 20 may only include the first plate 21, and the elastic arm 31 bracket 20 protrudes from one end of the first plate 21 in the first direction.

[0056] Please refer to the reference. Figure 8 and Figure 9 In one embodiment of this application, the rotating shaft 311 or the shaft hole 13 is provided on the side of the elastic arm 31 opposite to the deformation gap 315, and is located at the end of the elastic arm 31 away from the end connected to the first plate 21.

[0057] In this embodiment, the rotating shaft 311 or the shaft hole 13 is positioned on the side of the elastic arm 31 opposite to the deformation gap 315. This allows full utilization of the space on both sides of the elastic arm 31 in the second direction, with one side used for rotational installation and the other side providing space for deformation, without interference. Simultaneously, this simplifies the structure of the bracket 20, and the deformation gap 315 does not need to be excessively large, facilitating the manufacturing of the bracket 20. Furthermore, when the bracket 20 is installed in the storage slot 14 of the body 10 as described below, it facilitates the direct rotatable connection of the elastic arm 31 on the side opposite to the gap to the wall of the storage slot 14 in the second direction.

[0058] In one embodiment of this application, in order to improve the smoothness of the rotation of the bracket 20, grease can be applied to the abutment joint between the rotating shaft 311 and the shaft hole 13, as well as the abutment joint between the elastic arm 31 and the limiting protrusion 33.

[0059] Please refer to the reference. Figures 2 to 7 In one embodiment of this application, a storage groove 14 is provided on the back side 12 of the body 10; the shaft hole 13 and the limiting protrusion 33 are both provided on the groove wall of the storage groove 14, and the rotating shaft 311 and the elastic arm 31 are both provided on the bracket 20; in the folded state, the bracket 20 is accommodated in the storage groove 14.

[0060] In this embodiment, the storage slot 14 allows for a more compact mounting of the bracket 20 on the body 10, thereby reducing the overall size of the electronic device 100.
