Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic products, in particular to a tray mechanism and an electronic device. BACKGROUND

[0002] In electronic devices such as mobile phones and tablet computers, a SIM card (Subscriber Identity Module) and a memory card are usually installed on a tray and inserted into a card seat of the electronic device together with the tray. The tray is usually provided with an ejection mechanism to separate the tray from the card seat of the electronic device.

[0003] In related technologies, the ejection mechanism is composed of a push rod and a lever. When the tray is disassembled, the push rod is pushed by a push pin, the push rod pushes the lever, and the lever pushes the tray, thereby separating the tray and the card seat. The push rod and the lever are located in the length and width directions of the tray, respectively. The ejection mechanism occupies a large space in the length and width directions of the tray, and correspondingly, the volume of the card seat is also large, which is not conducive to the miniaturization of the electronic device. In order to solve the above technical problems, the present application provides a tray mechanism and an electronic device. SUMMARY

[0004] The purpose of the embodiments of the present application is to provide a tray mechanism and an electronic device to reduce the space occupied by the tray mechanism, thereby facilitating the miniaturization of the electronic device. The specific technical solutions are as follows:

[0005] The embodiments of the first aspect of the present application provide a tray mechanism, which includes a tray body and a tray head assembly. The tray head assembly includes a tray head body, a locking member and an elastic unlocking assembly arranged on the tray head body. The tray head body is slidably connected with the tray body in a first direction. The locking member is used to lock the tray body and the tray head assembly. The elastic unlocking assembly is used to release the locking of the tray body and the tray head assembly under the action of external pushing force, so that the tray head body slides in the first direction away from the tray body by a preset distance and at least partially pops out of the electronic device.

[0006] It can be seen from the above that the tray mechanism includes a tray body and a tray head assembly. The tray head assembly includes a tray head body, a locking piece arranged on the tray head body, and an elastic unlocking assembly. The locking piece is used to lock the tray body and the tray head assembly, so that the tray mechanism and the card seat of the electronic device can be mounted together. The elastic unlocking assembly is used to release the locking of the tray body and the tray head assembly under the action of an external pushing force, so that the tray head body slides in a first direction away from the tray body by a preset distance, and at least partially ejects the electronic device. In this way, the tray mechanism and the card seat can be separated by taking the tray head assembly, so that the tray mechanism can be disassembled. The tray head body and the tray body are slidably connected in the first direction. The first direction can be the length direction or the width direction of the tray body. That is, the tray mechanism of the embodiment is used to release the locking of the tray body and the tray head assembly, so that the related structure (ejection mechanism) of the tray head body at least partially ejecting the electronic device only occupies the space in the length direction or the width direction of the tray body, without occupying the space in both directions, so that the tray mechanism can be disassembled. Compared with the related art, the tray mechanism of the embodiment saves the space in the length direction or the width direction of the tray body, which is beneficial to the miniaturization of the electronic device.

[0007] In some embodiments of the present application, the tray body is provided with a first connecting portion near one side of the tray head assembly.

[0008] The tray head body is provided with a second connecting portion near one side of the tray body.

[0009] The first connecting portion and the second connecting portion are slidably connected by a connecting piece.

[0010] As can be seen from the above, the connecting piece is arranged to facilitate the disassembly and replacement of the tray body and the tray head assembly.

[0011] In some embodiments of the present application, the elastic unlocking assembly includes:

[0012] A pushing piece is slidably connected with the tray head body, and is used to slide in the first direction towards the tray body under the action of the external pushing force, and push the locking piece to make the locking piece disengage from the tray body.

[0013] An elastic piece is arranged between the tray head body and the tray body, and is used to deform and push the tray head body to make the tray head body slide in the first direction away from the tray body by a preset distance during the unlocking of the tray body and the tray head body, and reset the pushing piece.

[0014] As can be seen from the above, the tray mechanism is unlocked by pushing the pushing piece, which is simple to operate; and after the external pushing force is removed, the elastic piece can reset the pushing piece for the next unlocking of the locked tray mechanism, without the need for manual resetting operation, which is simple to operate; the tray head main body is pushed by the deformation of the elastic piece, and the size of the pushing force changes during the sliding process, so that the pushing process is more gentle, which is beneficial to prolong the service life of the tray mechanism; and the elastic piece has various types and controllable deformation, and can be accurately reset according to the material and elastic coefficient parameters, so as to have high reliability.

[0015] In some embodiments of the present application, the tray body further comprises:

[0016] The accommodating portion is formed with an accommodating groove;

[0017] The third connecting portion is located on one side of the accommodating portion close to the tray head assembly and connected with the elastic unlocking assembly;

[0018] The locking portion is used for connecting with the locking piece.

[0019] As can be seen from the above, the third connecting portion and the locking portion are both arranged on one side of the accommodating portion close to the tray head assembly, which is beneficial to the connection between the tray body and the tray head assembly, and when the tray body and the tray head assembly are locked, the third connecting portion and the locking portion can be at least partially located inside the tray head assembly, which is beneficial to the miniaturization of the electronic device.

[0020] In some embodiments of the present application, the tray head main body has an accommodating space on one side close to the tray body;

[0021] During the locking or unlocking process of the tray body and the tray head main body, the first connecting portion and the third connecting portion slide in the accommodating space.

[0022] As can be seen from the above, in this way, when the tray mechanism is in the locked state, the tray body can be partially embedded in the tray head main body, so as to reduce the volume of the tray mechanism, which is beneficial to the miniaturization design of the electronic device.

[0023] In some embodiments of the present application, the elastic piece comprises:

[0024] The first elastic piece is arranged between the tray body and the tray head main body, and is used for deforming and pushing the tray head main body during the unlocking process of the tray body and the tray head main body, so as to make the tray head main body slide in the first direction away from the tray body by a preset distance;

[0025] A second elastic member is arranged between the pushing member and the tray body, and is used to reset the pushing member after the tray body and the tray head body are unlocked and the external pushing force is removed.

[0026] As can be seen from the above, the first elastic member is mainly used to push the tray head body, and the second elastic member is mainly used to reset the pushing member. They are arranged separately, so that the pushing and resetting can be in place, and the reliability is higher.

[0027] In some embodiments of the present application, the third connecting part comprises a connecting body, and a first guide column and a second guide column are arranged on the connecting body; the first guide column and the second guide column extend from the connecting body to the tray head assembly along the first direction;

[0028] The first elastic member is sleeved outside the first guide column;

[0029] The second elastic member is sleeved outside the second guide column.

[0030] As can be seen from the above, the first guide column and the second guide column play a guiding role, so that the first elastic member and the second elastic member deform in the first direction, so that the tray head assembly is mainly subjected to the pushing force in the first direction, and thus the sliding is more smooth.

[0031] In some embodiments of the present application, the elastic member comprises a second elastic member;

[0032] The second elastic member is arranged between the pushing member and the tray body, and is used to reset the pushing member after the tray body and the tray head body are unlocked and the external pushing force is removed, and to make the pushing member push the locking member to drive the tray head body to slide a preset distance away from the tray body along the first direction.

[0033] As can be seen from the above, the unlocking of the tray mechanism and the resetting of the pushing member can be realized by the second elastic member, which is simple in structure, convenient to process, and beneficial to improve the production efficiency.

[0034] In some embodiments of the present application, the third connecting part comprises a connecting body, and a second guide column is arranged on the connecting body; the second guide column extends from the connecting body to the tray head assembly along the first direction;

[0035] The second elastic member is sleeved outside the second guide column.

[0036] As can be seen from the above, the second guide column plays a guiding role, so that the second elastic member deforms in the first direction, so that the tray head assembly is mainly subjected to the pushing force in the first direction, and thus the sliding is more smooth.

[0037] In some embodiments of the present application, the locking portion comprises:

[0038] A locking body is located on the side of the connecting body away from the accommodating portion; the locking body is provided with a relief structure for avoiding the elastic unlocking assembly;

[0039] A locking protrusion is formed by the locking body protruding towards the accommodating portion, for connecting with the locking piece.

[0040] As can be seen from the above, the relief structure allows the elastic unlocking assembly to be partially embedded in the locking portion, facilitating the miniaturization of the electronic device.

[0041] In some embodiments of the present application, in the second direction, the locking piece is located outside the locking portion of the tray body;

[0042] The locking piece is bent towards the locking protrusion on the side close to the accommodating portion, forming a first bending portion; the first bending portion is used for clamping with the locking protrusion;

[0043] The first direction and the second direction are perpendicular to each other.

[0044] As can be seen from the above, the tray body and the tray head assembly are locked by clamping, the connection method is simple and reliable, and it is convenient to unlock.

[0045] In some embodiments of the present application, the middle position of the locking piece is recessed towards the locking body, forming a recessed portion; after the recessed portion is pushed by the pushing piece, it moves in the second direction away from the locking portion, so that the first bending portion and the locking protrusion are disengaged.

[0046] As can be seen from the above, the setting of the recessed portion reduces the lowest point of the locking piece in the second direction, ensuring that the pushing piece can push the locking piece and ensuring the reliability of unlocking.

[0047] In some embodiments of the present application, in the second direction, the side of the locking body close to the locking piece is formed with a boss structure;

[0048] The side of the locking piece away from the accommodating portion is bent away from the locking body, forming a second bending portion; the second bending portion is used for abutting with the boss structure, so that the first bending portion has a tendency to move towards the locking protrusion.

[0049] As can be seen from the above, such a setting can make the clamping between the first bending portion and the locking protrusion more reliable.

[0050] In some embodiments of the present application, the pushing piece is formed with a protrusion near one end of the tray body, and the protrusion is used to push the recess.

[0051] As can be seen from the above, the setting of the protrusion improves the highest point of the pushing piece in the second direction, ensuring that the pushing piece can push the locking piece and guaranteeing the reliability of unlocking.

[0052] In some embodiments of the present application, the tray head body is further provided with a limiting protrusion, and in the first direction, the limiting protrusion is located on the side of the protrusion away from the tray body, used to abut against the protrusion to limit the sliding distance of the pushing piece in the first direction away from the tray body.

[0053] As can be seen from the above, it can be ensured that the pushing piece will not be pulled out of the tray head body during the resetting process due to excessive force of the second elastic piece, thereby guaranteeing the reliability of the tray mechanism.

[0054] In some embodiments of the present application, the locking piece is integrally injection molded with the tray head body.

[0055] As can be seen from the above, the injection molding connection has high reliability.

[0056] In some embodiments of the present application, the tray head body is provided with an unlocking hole, and the unlocking hole is used to accommodate an external unlocking piece so that the external unlocking piece pushes the elastic unlocking assembly under the action of external pushing force.

[0057] As can be seen from the above, only the external unlocking piece needs to be pushed to realize the unlocking of the tray mechanism, and the unlocking method is simple.

[0058] Embodiments of the second aspect of the present application propose an electronic device, which comprises a shell, a card seat, and a tray mechanism according to any one of the embodiments of the first aspect.

[0059] The card seat is fixedly arranged inside the shell.

[0060] The shell is provided with a plug-in hole at a position corresponding to the card seat.

[0061] The tray mechanism is arranged in the card seat through the plug-in hole in a detachable manner.

[0062] The tray head body of the tray mechanism is provided with an unlocking hole, and an inlet of the unlocking hole is exposed outside the shell. The unlocking hole is used to accommodate an external unlocking piece, so that the external unlocking piece slides along the unlocking hole and pushes the elastic unlocking assembly under the action of external pushing force, to unlock the tray body and the tray head assembly.

[0063] As can be seen from the above, the electronic device of this application embodiment includes the tray mechanism of any of the above embodiments. The tray head body of the tray mechanism is slidably connected to the tray body in a first direction. The first direction can be the length direction or the width direction of the tray body. That is, the tray mechanism of this application embodiment is used to release the locking between the tray body and the tray head assembly so that the tray head body can at least partially pop out the relevant structure (ejection mechanism) of the electronic device. It only needs to occupy the space in the length direction or the width direction of the tray body, without occupying the space in both directions, so that the disassembly and assembly of the tray mechanism can be realized. Compared with the related technology, the solution that occupies a large space in both the length and width directions of the tray, the tray mechanism of this application embodiment saves the space in the length direction or the width direction of the tray body, which is beneficial to the miniaturization of the electronic device.

DETAILED DESCRIPTION

[0100] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0101] In order to facilitate clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the same items or similar items with basically the same functions and effects are distinguished by using "first", "second", etc. For example, the first swing arm and the second swing arm are used to distinguish different swing arms, and do not limit the sequence. Those skilled in the art can understand that "first", "second", etc. do not limit the quantity and position, and "first", "second", etc. also do not necessarily mean different.

[0102] It should be noted that in the present application, "exemplarily" or "for example" and the like are used to represent as an example, illustration or description. Any embodiment or design scheme described as "exemplarily" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the use of "exemplarily" or "for example" and the like is intended to present the relevant concept in a specific manner.

[0103] In electronic devices such as mobile phones and tablets, SIM cards (Subscriber Identity Modules) and memory cards are typically installed on a tray and inserted into the card slot of the electronic device along with the tray. The tray is usually equipped with an ejection mechanism to separate the tray from the card slot of the electronic device. In related technologies, the ejection mechanism consists of a push rod and a lever. When disassembling the tray, a push pin pushes the push rod, which in turn pushes the lever, which in turn pushes the tray, thereby separating the tray from the card slot. The push rod and lever are located in the length and width directions of the tray, respectively. The ejection mechanism occupies a large space in both the length and width directions of the tray, resulting in a correspondingly large card slot, which is detrimental to the miniaturization of the electronic device. To solve the above technical problems, embodiments of this application provide a tray mechanism and an electronic device.

[0104] The electronic devices provided in this application can be mobile phones, tablets, wearable devices, in-vehicle devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), and other electronic devices equipped with SIM cards or memory cards. This application does not limit the specific type of electronic device; for ease of understanding, a mobile phone will be used as an example for the following description.

[0105] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an electronic device according to an embodiment of this application. The electronic device may include a tray mechanism 10, a housing 20, and a display screen 40. The display screen 40 may be mounted on the housing 20. The housing 20 may be made of metal, plastic, ceramic, or glass. The display screen 40 may be a liquid crystal display (LCD) screen, an organic light-emitting diode (OLED) screen, etc., wherein the OLED screen may be a flexible display screen or a rigid display screen. The display screen 40 may be a regular display screen 40, or an irregularly shaped display screen 40, a folding display screen 40, etc. For example, the display screen 40 may be able to rotate and fold relatively freely to form an arc, a sphere, a cylinder, etc. The display screen 40 may be disposed on the front of the electronic device, or on the back of the electronic device, or on both the front and back of the electronic device. The front of the electronic device can be understood as the side facing the user when using the electronic device, and the back of the electronic device can be understood as the side facing away from the user when using the electronic device.

[0106] For example, the display screen 40 is arranged on the front surface of the electronic device. In terms of arrangement range, the display screen 40 can cover all areas of the front surface of the electronic device, i.e., the electronic device can form a full-screen, and at this time, the display screen 40 not only has a display function, but also usually has a touch function, i.e., the electronic device can be operated by clicking the display screen 40. Alternatively, the display screen 40 can only cover a partial area of the front surface of the electronic device, and at this time, the display screen 40 can have a touch function or only have a display function; when only having a display function, the area of the shell 20 where the display screen 40 is not arranged can be configured with corresponding human-computer interaction elements such as buttons, so as to operate the electronic device. These human-computer interaction elements can be arranged at any position of the front surface, back surface or side surface of the electronic device.

[0107] As shown in Figure 1 and Figure 2a , the first direction is defined as the length direction of the tray body 100, the second direction is defined as the thickness direction of the tray body 100, and the third direction is defined as the width direction of the tray body 100, and the first direction, the second direction and the third direction are perpendicular to each other. Figure 2a As shown in the embodiment, the length direction of the tray body 100 is consistent with the length direction of the electronic device, the width direction of the tray body 100 is consistent with the width direction of the electronic device, and the thickness direction of the tray body 100 is consistent with the thickness direction of the electronic device. In some other embodiments of the present application, the first direction can also be the width direction of the tray body 100, the third direction can also be the length direction of the tray body 100, and the length direction of the tray body 100 can be inconsistent with the length direction of the electronic device, which can be set according to actual needs, and the present application does not make any limitation in this regard. Figure 1 As shown in

[0108] and Figure 1 , the electronic device further comprises a card seat 30 and a tray mechanism 10. The shell 20 is formed with a receiving space for arranging various components of the electronic device, such as a battery, an antenna, a circuit board 50 and a camera module. At the same time, the shell 20 can also play a role in protecting the electronic device. The card seat 30 can be fixedly connected with the circuit board 50, and the circuit board 50 is fixedly connected with the shell 20; the SIM card 60 realizes electrical connection with the circuit board 50 through the card seat 30. As shown in Figure 2a Figure 2b Figure 2b ​​As shown in the installation schematic view (unlocked state) of the tray mechanism 10 of the embodiment, the card seat 30 is fixedly arranged inside the shell 20; the shell 20 is provided with a plug-in hole 21 at a position corresponding to the card seat 30, and the tray mechanism 10 is detachably connected to the card seat 30 through the plug-in hole 21; the tray mechanism 10 comprises a tray body 100 and a tray head assembly 200; the tray head assembly 200 comprises a tray head main body 210, and the tray head main body 210 of the tray mechanism 10 is provided with an unlocking hole 214; the inlet of the unlocking hole 214 is exposed outside the shell 20, and the unlocking hole 214 is used for accommodating an external unlocking member (not shown in the figure), such as a thimble, so that the external unlocking member slides along the unlocking hole 214 under the action of external thrust force and pushes the elastic unlocking assembly (not shown in the figure) to unlock the tray body 100 and the tray head assembly 200. Figure 2b

[0109] It can be understood that the tray mechanism 10 has a locked state and an unlocked state; when the tray mechanism 10 is in the locked state, as shown in FIG. 1, the tray head assembly 200 is embedded inside the shell 20; when the tray mechanism 10 is in the unlocked state, as shown in FIG. 2, at least part of the tray head assembly 200 is popped out of the shell 20. Figure 2a Figure 2b At this time, the tray mechanism 10 can be separated from the card seat 30 by pulling the tray head assembly 200, so as to realize the disassembly of the tray mechanism 10. When installing, the tray body 100 is inserted into the card seat 30 from the plug-in hole 21, and then the tray head assembly 200 is pushed, so as to realize the installation of the tray mechanism 10 and the card seat 30.

[0110] Optionally, as shown in FIG. 3, which is an exploded structure schematic view of the tray mechanism 10, the outer side of the tray body 100 can be provided with a clamping groove 122, and the side wall of the card seat 30 can be provided with an elastic protrusion 31; when the tray mechanism 10 is installed in the card seat 30, the elastic protrusion 31 is clamped in the clamping groove 122, so as to realize the detachable connection between the two, and the connection mode is simple and reliable. Figure 2c Figure 2c Figure 2a As shown in FIG. 4, which is a schematic view of the SIM card 60, the SIM card 60 is usually plate-shaped, comprising two plate surfaces 61 oppositely arranged in the thickness direction and an outer peripheral wall 62 connecting the two plate surfaces 61, and the outer peripheral wall 62 usually comprises a plurality of side wall surfaces, and the number of the side wall surfaces is related to the shape of the SIM card 60. Of the two plate surfaces 61, only one plate surface 61 can be provided with contacts 63 of a chip to be electrically connected to electronic devices inside the electronic device. Alternatively, the two plate surfaces 61 can be respectively provided with contacts 63 of different chips, and at this time, the SIM card 60 is equivalent to integrating two ordinary SIM cards.

[0112] ​​​​​​It should be noted that the structure shown in the figure does not constitute a specific limitation on the electronic device, and the electronic device can include more or fewer components than the figure, for example, the electronic device can also include one or more of the following components: battery, flash, fingerprint identification module, earpiece, key, sensor, etc. For example, the electronic device can also not include the display screen 40; in addition, the electronic device can also be arranged in a different manner than the figure.

[0113] Optionally, as shown in Figure 2c , the tray mechanism 10 can have two accommodation grooves 121, which are arranged back to back and can respectively place a SIM card 60 or a memory card, and save the space occupied by the tray mechanism 10 in the first direction and the second direction.

[0114] The structure of the tray mechanism 10 of the embodiment of the present application will be described in detail below.

[0115] As shown in Figure 3a and Figure 3b , Figure 3a is a structure diagram of the first perspective view of the tray mechanism 10 of the first embodiment of the present application (locked state), Figure 3b is Figure 3a an exploded structure diagram, the embodiment of the present application proposes a tray mechanism 10, which includes a tray body 100 and a tray head assembly 200. Specifically, the tray head assembly 200 includes a tray head body 210, a locking member 220 arranged on the tray head body 210, and an elastic unlocking assembly 230; the tray head body 210 is slidably connected with the tray body 100 in the first direction; the locking member 220 is used to lock the tray body 100 and the tray head assembly 200; the elastic unlocking assembly 230 is used to release the locking of the tray body 100 and the tray head assembly 200 under the action of an external pushing force, so that the tray head body 210 slides in the first direction away from the tray body 100 by a preset distance and at least partially pops out of the electronic device.

[0116] The tray mechanism 10 of the embodiment of the present application comprises a tray body 100 and a tray head assembly 200. The tray head assembly 200 comprises a tray head body 210, and a locking piece 220 and an elastic unlocking assembly 230 arranged on the tray head body 210; the locking piece 220 is used to lock the tray body 100 and the tray head assembly 200, at this time, the tray mechanism 10 and the card seat 30 of the electronic device can be installed together; the elastic unlocking assembly 230 is used to release the locking of the tray body 100 and the tray head assembly 200 under the action of an external pushing force, so that the tray head body 210 slides in a first direction to a direction away from the tray body 100 by a preset distance, and at least partially ejects the electronic device, so that the tray mechanism 10 and the card seat 30 can be separated by taking the tray head assembly 200, thereby realizing the disassembly of the tray mechanism 10. The tray head body 210 of the embodiment of the present application is slidably connected with the tray body 100 in the first direction; the first direction can be the length direction or the width direction of the tray body 100, that is, the related structure (ejection mechanism) of the tray mechanism 10 of the embodiment of the present application for releasing the locking of the tray body 100 and the tray head assembly 200 to at least partially eject the electronic device only needs to occupy the space in the length direction or the width direction of the tray body 100, without occupying the space in both directions, thereby realizing the disassembly of the tray mechanism 10; compared with the scheme in the related art which occupies a large space in the length and width directions of the tray, the tray mechanism 10 of the embodiment of the present application saves the space in the length direction or the width direction of the tray body 100, and is beneficial to the miniaturization of the electronic device.

[0117] As shown in Figure 3a to Figure 3e , Figure 3c is an A-A sectional view of Figure 3a , Figure 3d is a B-B sectional view of Figure 3c , Figure 3e is a structure schematic diagram of the tray mechanism 10 of the first embodiment of the present application from a second perspective (locking state), which shows the structure of the tray mechanism 10 of the first embodiment of the present application in the locking state; as shown in Figure 4a and Figure 4b , Figure 4a is a structure schematic diagram of the tray mechanism 10 of the first embodiment of the present application from a first perspective (unlocking state), Figure 4b is a partial enlarged view of Q of Figure 4a , which shows the structure of the tray mechanism 10 of the first embodiment of the present application when unlocking; as can be seen, in the process of unlocking the tray mechanism 10, the tray head assembly 200 slides in the first direction by a preset distance.

[0118] Referring back to Figure 3aThe tray body 100 can include a metal part 101 and a non-metal part 102; the metal part 101 and the non-metal part 102 are fixedly connected and jointly surround the accommodating groove 121.

[0119] In the first embodiment of the present application, as shown in Figure 3b and Figure 3c The elastic unlocking assembly 230 includes a pushing piece 231 and an elastic piece 232. The pushing piece 231 is in sliding connection with the tray head body 210 and is used to slide in the first direction, towards the tray body 100, under the action of external pushing force, and push the locking piece 220, so that the locking piece 220 is disengaged from the tray body 100. The elastic piece 232 is arranged between the tray head body 210 and the tray body 100 and is used to deform and push the tray head body 210 in the process of unlocking the tray body 100 and the tray head body 210, so that the tray head body 210 slides in the first direction, away from the tray body 100, by a preset distance, and reset the pushing piece 231. By pushing the pushing piece 231, the locking of the tray mechanism 10 can be unlocked, which is simple to operate. After the external pushing force is removed, the elastic piece 232 can reset the pushing piece 231, so that the next unlocking of the tray mechanism 10 after locking does not need to be manually reset, which is simple to operate. By deforming the elastic piece 232 to push the tray head body 210, the size of the pushing force changes in the sliding process, the pushing process is more gentle, which is beneficial to prolong the service life of the tray mechanism 10. The elastic piece 232 has various types and controllable deformation, and can be designed to accurately reset the pushing piece 231 according to the material and elastic coefficient and other parameters, which has high reliability.

[0120] In the first embodiment of the present application, the elastic piece 232 is a spring. In some other embodiments of the present application, the elastic piece 232 can also be a rubber piece or the like, which can realize the above-mentioned functions, and the present application does not limit this.

[0121] In the first embodiment of the present application, as shown in Figure 3dAs shown, the elastic element 232 includes a first elastic element 2321 and a second elastic element 2322. The first elastic element 2321 is disposed between the pallet body 100 and the pallet head body 210, and is used to deform and push the pallet head body 210 during the unlocking process of the pallet body 100 and the pallet head body 210, so that the pallet head body 210 slides a preset distance away from the pallet body 100 along a first direction. The second elastic element 2322 is disposed between the pusher 231 and the pallet body 100, and is used to reset the pusher 231 after the pallet body 100 and the pallet head body 210 are unlocked and the external pushing force is removed. The first elastic element 2321 is mainly used to push the pallet head body 210, and the second elastic element 2322 is mainly used to reset the pusher 231. The separate placement ensures that both pushing and resetting are in place, resulting in higher reliability.

[0122] like Figure 3d As shown, when the pallet mechanism 10 is in the locked state, both the first elastic member 2321 and the second elastic member 2322 can be in the compressed state so that during the unlocking process, the first elastic member 2321 can push the pallet head assembly 200 to slide away from the pallet body along the first direction; and after the lock is unlocked, the pushing member 231 can be reset by the second elastic member 2322.

[0123] Optionally, such as Figure 3d As shown, there can be two first elastic elements 2321. In the third direction, the two first elastic elements 2321 are symmetrically arranged on both sides of the second elastic element 2322. In this way, during the process of the second elastic element 2322 pushing the tray head body 210, the force on both sides of the tray head body 210 is more balanced, so that it slides more smoothly.

[0124] In the first embodiment of this application, as Figure 3d As shown, the tray head body 210 is provided with an unlocking hole 214; the unlocking hole 214 is used to accommodate an external unlocking component (not shown in the figure), so that the external unlocking component pushes the elastic unlocking component 230 under the action of external pushing force. The tray mechanism 10 can be unlocked simply by pushing the external unlocking component, and the unlocking method is simple.

[0125] like Figure 3d As shown, in use, the external unlocking member extends into the unlocking hole 214, and then pushes the pusher 231. The pusher 231 slides along the first direction toward the tray body 100, thereby compressing the second elastic member 2322. Thus, when the external pushing force is removed, the pusher 231 can slide along the first direction away from the tray body 100 under the action of the elastic force of the second elastic member 2322, thereby achieving reset.

[0126] Optionally, such as Figure 3dAs shown, the outer wall of the end of the pushing piece 231 away from the tray body 100 can be provided with a second sealing rubber ring 233 to fill the gap between the pushing piece 231 and the inner wall of the unlocking hole 214, thereby improving the sealing performance of the tray mechanism 10 and prolonging the service life of the electronic device.

[0127] In the first embodiment of the present application, as shown in Figure 5a and Figure 5b , Figure 5a is a connection relationship diagram of the tray body 100, the tray head assembly 200 and the connecting piece 300 in the first embodiment of the present application, Figure 5b is a partial enlarged view of P of Figure 5a , the side of the tray body 100 close to the tray head assembly 200 is provided with a first connecting part 110; the side of the tray head body 210 close to the tray body 100 is provided with a second connecting part 2111; the first connecting part 110 and the second connecting part 2111 are slidingly connected through the connecting piece 300. The connecting piece 300 is arranged to facilitate the disassembly and assembly between the tray body 100 and the tray head assembly 200, and facilitate replacement and maintenance.

[0128] Specifically, as shown in Figure 5b , the first connecting part 110 can be provided with a sliding connection hole 111, and the second connecting part 2111 can be provided with a first fixing hole 21111, and the connecting piece 300 is arranged in the sliding connection hole 111 and the first fixing hole 21111. Among them, the shape of the connecting piece 300 is matched with the shape of the first fixing hole 21111, and in the first direction, they are relatively fixed; the sliding connection hole 111 is a strip-shaped hole extending in the first direction, and in the process of locking or unlocking the tray mechanism 10, the connecting piece 300 slides in the sliding connection hole 111 to drive the tray head assembly 200 to slide in the first direction away from the tray body 100 by a preset distance; it can be understood that the numerical range of the preset distance is related to the size of the sliding connection hole 111 in the first direction, and by reasonably setting the shape and size of the sliding connection hole 111, the sliding distance of the tray head assembly 200 can be accurately limited.

[0129] As shown in Figure 5b , the number of the first connecting part 110, the second connecting part 2111 and the connecting piece 300 can be two; the two first connecting parts 110 are arranged in the third direction, and the two second connecting parts 2111 are arranged in the third direction, which can improve the connection stability.

[0130] Optionally, the connecting piece 300 can be a rivet, which is easy to install, and its cylindrical shape is conducive to its sliding in the sliding connection hole 111. In some other embodiments of the present application, the connecting piece 300 can also be a part with other structures and shapes, as long as it can meet the above requirements, which are not limited in the present application.

[0131] In the first embodiment of the present application, as shown in Figure 5b the tray head body 210 is close to one side of the tray body 100 and has a containing space; during the locking or unlocking process of the tray body 100 and the tray head body 210, the first connecting part 110 and the third connecting part 130 (the structure of the third connecting part 130 will be described in detail later) slide in the containing space. In this way, when the tray mechanism 10 is in the locked state, the tray body 100 can be partially embedded in the tray head body 210, thereby reducing the volume of the tray mechanism 10 and facilitating the miniaturization design of the electronic device.

[0132] As shown in Figure 5b and 6a , Figure 6a is a structural schematic view of the tray head assembly 200 in the first embodiment of the present application, and the side of the tray head body 210 facing the tray body 100 is further provided with a fourth connecting part 2114, the fourth connecting part 2114 and the second connecting part 2111 are oppositely and spacedly arranged in the second direction, and the first connecting part 110 is clamped between the second connecting part 2111 and the fourth connecting part 2114; the fourth connecting part 2114 is provided with a second fixing hole 21141, one end of the connecting piece 300 sequentially passes through the first fixing hole 21111, the sliding connecting hole 111 and the second fixing hole 21141, thereby realizing the connection between the tray head body 210 and the tray body 100; in this way, the connection is more reliable, the shaking of the tray body 100 in the second direction can be reduced, and the structural stability is improved.

[0133] Specifically, as shown in Figure 6a , the number of the fourth connecting part 2114 can also be two, and the two fourth connecting parts 2114 are correspondingly arranged with the two second connecting parts 2111, and one second fixing hole 21141 is formed on each fourth connecting part 2114. In the third direction, the two fourth connecting parts 2114 are spacedly arranged to provide a sliding space for the tray body 100 in the tray head body 210.

[0134] As shown in Figure 6a and Figure 6b , Figure 6b is an exploded structural schematic view of the tray head body 210 in the first embodiment of the present application, and the tray head body 210 can include a body part 211 and a tray cover 212, the locking piece 220 and the elastic unlocking assembly 230 are arranged on the body part 211, and referring back to Figure 2aThe tray cover 212 covers the side of the main body 211 away from the tray body 100 and is exposed on the outside of the electronic device, flush with the outer surface of the housing 20. This arrangement allows the main body 211 and the tray cover 212 to be made of different materials, so that the same main body 211 can correspond to tray covers 212 of different colors and materials, adapting to different electronic devices and improving the versatility of the tray mechanism 10.

[0135] like Figure 6b As shown, a first sealing ring 213 can be provided on the outside of the main body 211 of the tray head body 210 to improve the sealing performance of the electronic device and extend its service life.

[0136] In the first embodiment of this application, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of the tray body 100 in the first embodiment of this application. The tray body 100 also includes a receiving portion 120, a third connecting portion 130, and a locking portion 140; the receiving portion 120 has a receiving groove 121; Return to Reference Figure 5b The third connecting portion 130 is located on the side of the receiving portion 120 near the tray head assembly 200 and is connected to the elastic unlocking component 230; the locking portion 140 is used to connect to the locking member 220. The arrangement of both the third connecting portion 130 and the locking portion 140 on the side of the receiving portion 120 near the tray head assembly 200 facilitates the connection between the tray body 100 and the tray head assembly 200. When the tray body 100 and the tray head assembly 200 are locked, the third connecting portion 130 and the locking portion 140 can be at least partially located inside the tray head assembly 200, which is beneficial for the miniaturization of electronic devices.

[0137] In the first embodiment of this application, such as Figure 7 As shown, the third connecting part 130 includes a connecting body 131, and a first guide post 132 and a second guide post 133 spaced apart on the connecting body 131; Return to reference Figure 3d The first guide post 132 and the second guide post 133 extend from the connecting body 131 toward the tray head assembly 200 along a first direction; the first elastic element 2321 is sleeved on the outside of the first guide post 132; and the second elastic element 2322 is sleeved on the outside of the second guide post 133. The first guide post 132 and the second guide post 133 serve a guiding function, causing the first elastic element 2321 and the second elastic element 2322 to deform in the first direction, thereby causing the tray head assembly 200 to be mainly subjected to the pushing force in the first direction, thus making its sliding smoother.

[0138] Specifically, continue to refer to Figure 3dThe first guide hole 2113 is arranged on one side of the tray head body 210, and is used for accommodating the first guide column 132 and the first elastic member 2321. The first guide hole 2113 is slidably arranged in the first guide hole 2113, and the first guide hole 2113 plays a guiding role, so that the sliding of the tray head assembly 200 is smoother. The two ends of the first elastic member 2321 are used for abutting against the bottom wall of the first guide hole 2113 and the connecting body 131, respectively.

[0139] As shown in Figure 3d , the second guide hole 2312 is arranged on one side of the push piece 231 close to the tray body 100. The second guide hole 2312 is used for accommodating the second guide column 133 and the second elastic member 2322. The second guide column 133 is slidably connected in the second guide hole 2312. The two ends of the second elastic member 2322 are used for abutting against the bottom wall of the second guide hole 2312 and the connecting body 131, respectively.

[0140] In the first embodiment of the present application, as shown in Figure 5b and Figure 7 , the locking part 140 includes a locking body 141 and a locking protrusion 142. The locking part 140 is located on one side of the connecting body 131 away from the accommodating part 120. The locking body 141 is provided with a avoiding structure 1412 for avoiding the elastic unlocking assembly 230. The locking protrusion 142 is protruded from the locking body 141 to the accommodating part 120, and is used for connecting with the locking piece 220. The avoiding structure 1412 makes the elastic unlocking assembly 230 can be partially embedded in the locking part 140, which is beneficial to the miniaturization of the electronic device.

[0141] As shown in Figure 6a and Figure 8 , Figure 8 is a structural schematic view of the locking piece 220 in the first embodiment of the present application. The locking piece 220 extends along a third direction, and the two ends thereof are fixedly connected with two second connecting parts 2111, respectively. The two ends of the locking piece 220 can be respectively provided with a third fixed hole 224 corresponding to the position of the first fixed hole 21111, so that the connecting piece 300 can pass through the third fixed hole 224. The interval region between the two second connecting parts 2111 provides a space for the deformation of the locking piece 220 in the second direction.

[0142] In the first embodiment of the present application, the locking piece 220 and the tray head body 210 can be integrally injection molded. The injection molding connection has high reliability. In some other embodiments of the present application, the two parts can be separately arranged, which is not limited in the present application.

[0143] Optionally, the locking piece 220 can be made of metal.

[0144] In the first embodiment of the present application, as shown in Figure 8 and Figure 9 , as shown in Figure 9 is the connection relationship diagram (locked state) of the first bending part 221 and the locking protrusion 142 in the first embodiment of the present application, in the second direction, the locking part 220 is located outside the locking part 140 of the tray body 100; the side of the locking part 220 close to the containing part 120 is bent towards the locking protrusion 142 to form the first bending part 221; the first bending part 221 is used for clamping with the locking protrusion 142. The tray body 100 and the tray head assembly 200 are locked by clamping, the connection mode is simple and reliable, and it is convenient to unlock.

[0145] In the first embodiment of the present application, as shown in Figure 7 to Figure 10 , as shown in Figure 10 is the connection relationship diagram (locked state) of the second bending part 223 and the boss structure 1411 in the first embodiment of the present application, in the second direction, the locking body 141 is formed with the boss structure 1411 on the side close to the locking part 220; the side of the locking part 220 away from the containing part 120 is bent away from the locking body 141 to form the second bending part 223; the second bending part 223 is used for abutting with the boss structure 1411, so that the first bending part 221 has a tendency to move towards the locking protrusion 142. In this way, the clamping between the first bending part 221 and the locking protrusion 142 can be more reliable.

[0146] Optionally, the number of the first bending part 221 can be two, and the two first bending parts 221 are arranged at intervals in the third direction; the number of the second bending part 223 can be two, and the two second bending parts 223 are arranged at intervals in the third direction, so that the connection reliability can be increased.

[0147] In the first embodiment of the present application, as shown in Figure 8 , the middle position of the locking part 220 is recessed towards the locking body 141 to form the recessed part 222; as shown in Figure 9 to Figure 11b , as shown in Figure 11a is the unlocking process diagram of the tray mechanism 10 in the first embodiment of the present application (the pushing part 231 pushes the locking part 220), Figure 11b is the unlocking process diagram of the tray mechanism 10 in the first embodiment of the present application (the tray head assembly 200 pops out), after the recessed part 222 is pushed by the pushing part 231, it moves along the second direction, away from the locking part 140, so that the first bending part 221 and the locking protrusion 142 are disengaged. The setting of the recessed part 222 lowers the lowest point of the locking part 220 in the second direction, ensures that the pushing part 231 can push the locking part 220, and guarantees the reliability of unlocking.

[0148] In the first embodiment of the present application, asFigure 11a As shown, the pushing piece 231 is formed with a protrusion 2311 near one end of the tray body 100, and the protrusion 2311 is used to push the recessed part 222. The arrangement of the protrusion 2311 increases the highest point of the pushing piece 231 in the second direction, and ensures that the pushing piece 231 can push the locking piece 220, and guarantees the reliability of the unlocking.

[0149] Optionally, the protrusion 2311 can be formed only on the side close to the locking piece 220; or can be formed on both sides close to and away from the locking piece 220, so that the assembly is not mistaken, and the production efficiency is improved.

[0150] In the first embodiment of the present application, referring back to Figure 3c , the tray head body 210 is further provided with a limiting protrusion 2112, which is located on the side of the protrusion 2311 away from the tray body 100 in the first direction, and is used to abut against the protrusion 2311 to limit the sliding distance of the pushing piece 231 in the first direction, i.e., the direction away from the tray body 100. Thus, it can be ensured that the pushing piece 231 will not be pulled out of the tray head body 210 due to excessive pushing force of the second elastic piece 2322 during the resetting process, so as to guarantee the reliability of the tray mechanism 10. Specifically, the limiting protrusion 2112 can be formed on the inner wall of the unlocking hole 214.

[0151] The unlocking process of the tray mechanism 10 can refer to Figure 11a to Figure 11c , Figure 11a FIG. 1 is a process diagram of the unlocking of the tray mechanism 10 of the first embodiment of the present application (the pushing piece 231 pushes the locking piece 220), Figure 11b FIG. 2 is a process diagram of the unlocking of the tray mechanism 10 of the first embodiment of the present application (the tray head assembly 200 is ejected), Figure 11c FIG. 3 is a process diagram of the unlocking of the tray mechanism 10 of the first embodiment of the present application (the pushing piece 231 is reset), the pushing piece 231 slides along the unlocking hole 214 to the tray body 100, and the second elastic piece 2322 is compressed, and when the pushing piece 231 slides to the position as shown in Figure 11a , the protrusion 2311 of the pushing piece 231 contacts the recessed part 222 of the locking piece 220, and starts to push the locking piece 220, and the locking piece 220 deforms in the second direction, i.e., the direction away from the locking part 140 (see Figure 9 ), as shown in Figure 11a is the perspective view, i.e., the locking piece 220 deforms upward; when the locking piece 220 is separated from the locking part 140, the tray head assembly 200 and the tray body 100 are unlocked, and at this time, as shown in Figure 11b , the tray head body 210 slides in the first direction, i.e., the direction away from the tray body 100; and when the external pushing force is removed, as shown in Figure 11cAs shown, the pushing piece 231 is reset under the action of the second elastic piece 2322.

[0152] The tray mechanism 10 of the second embodiment of the present application is different from the tray mechanism 10 of the first embodiment of the present application in that the tray mechanism 10 of the second embodiment of the present application is provided with only the second elastic piece 2322, and the unlocking of the tray mechanism 10 and the reset of the pushing piece 231 are realized by the second elastic piece 2322. Correspondingly, part of the structure of the tray body 100 and part of the structure of the tray head assembly 200 also need to be adjusted correspondingly. The structure of the tray mechanism 10 of the second embodiment of the present application will be described in detail below.

[0153] Figure 12a to Figure 12d As shown, the structure of the tray mechanism 10 of the second embodiment of the present application in the locked state is shown, Figure 12a the structure diagram of the tray mechanism 10 of the second embodiment of the present application (locked state) is shown, Figure 12b the exploded structure diagram of Figure 12a is shown, Figure 12c the C-C sectional view of Figure 12a is shown, Figure 12d the D-D sectional view of Figure 12c is shown; as Figure 13a and Figure 13b shown, the structure of the tray mechanism 10 of the second embodiment of the present application in the unlocked state is shown, Figure 13a the structure diagram of the tray mechanism 10 of the second embodiment of the present application (unlocked state) is shown, Figure 13b the M local enlarged diagram of Figure 13a is shown.

[0154] As Figure 12b shown, the tray body 100 and the tray head assembly 200 in the second embodiment of the present application are also connected through the connecting piece 300, and the specific connection mode is the same as that in the first embodiment of the present application, which will not be described here.

[0155] In the second embodiment of the present application, as Figure 12c and Figure 12d shown, the elastic piece 232 includes the second elastic piece 2322; the second elastic piece 2322 is arranged between the pushing piece 231 and the tray body 100, and is used to reset the pushing piece 231 after the tray body 100 and the tray head body 210 are unlocked and the external pushing force is removed, and to make the pushing piece 231 push the locking piece 220, so as to drive the tray head body 210 to slide a preset distance in the first direction away from the tray body 100. The unlocking of the tray mechanism 10 and the reset of the pushing piece 231 can be realized by the second elastic piece 2322, which is simple in structure, convenient to process, and beneficial to improve the production efficiency.
