Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This invention claims priority to a Chinese patent application filed with the China Patent Office on September 7, 2021, bearing application number 202111044274.7 and titled "Card tray assembly and electronic device," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of communications technology, and more particularly to card tray assemblies and electronic devices. [Background technology]

[0003] Currently, all electronic devices on the market are equipped with cards such as user identification cards and memory cards to meet the usage needs of the electronic devices, and accordingly, a card tray for placing the cards is required.

[0004] However, in practical applications, when a card tray needs to be removed from an electronic device, the conventional method involves inserting an ejection pin or a similar tool into the ejection hole and applying a driving force to eject the card tray. However, if the user does not have or has lost the ejection pin and cannot find a similar tool, the user will be unable to eject the card tray from the electronic device, resulting in a relatively poor user experience. Therefore, how to easily eject a card tray containing cards from an electronic device has become an important issue that people are concerned about. Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the embodiments of the present application is to provide a card tray assembly and an electronic device that can solve the problem that the card tray of an electronic device is difficult to remove.

[0006] In order to solve the above technical problems, the present application is realized as follows: [Means for solving the problem]

[0007] According to a first aspect, an embodiment of the present application provides a card tray assembly, the card tray assembly comprising: a positioning tube, the positioning tube being provided with a first fitting groove, a second fitting groove, and a first guide slope, the inner surface of the first fitting groove being connected to the inner surface of the second fitting groove via the first guide slope; a card tray having an action portion provided on the card tray; A telescopic assembly, the telescopic assembly including a telescopic positioning member and an elastic member, the telescopic positioning member being movably installed on the positioning tube, at least a portion of the telescopic positioning member being located within the positioning tube, the telescopic positioning member being provided with a positioning protrusion, one end of the elastic member being connected to the telescopic positioning member, and the other end of the elastic member being a fixed end of the telescopic assembly; The engagement between the positioning protrusion and the first guide slope causes the acting portion and the elastic member to drive the expandable positioning member to rotate between a first position and a second position, and when the expandable positioning member is in the first position, the positioning protrusion engages with the first engaging groove in a position-restricting manner, and the card tray is in an extended state, and when the expandable positioning member is in the second position, the positioning protrusion engages with the second engaging groove in a position-restricting manner, and the card tray is in a retracted state.

[0008] According to a second aspect, an embodiment of the present application provides an electronic device, the electronic device including a housing and a card tray assembly, the housing having a card tray hole, the card tray assembly being installed in the card tray hole, and the card tray assembly being the card tray assembly described above. [Effects of the Invention]

[0009] In an embodiment of the present application, the positioning tube is provided with a first fitting groove, a second fitting groove, and a first guide slope, the card tray is provided with an action portion, and the expandable positioning member is provided with positioning protrusions that can be fitted into the first fitting groove and the second fitting groove to regulate position, respectively, so that when a user applies an action force to the card tray, the action portion of the card tray and the elastic member both apply an action force to the expandable positioning member.

[0023] When the force applied by the operating member to the expandable positioning member is greater, the expandable positioning member moves, gradually disengaging the positioning protrusion from the first groove and engaging with the first inclined guide surface, thereby driving the expandable positioning member to rotate with the cooperation of the elastic member, so that the positioning protrusion engages with the second groove, and the card tray is in a retracted state. When the user presses the card tray again, the expandable positioning member moves, gradually disengaging the positioning protrusion from the second groove and engaging with the first inclined guide surface, thereby driving the expandable positioning member to rotate with the cooperation of the elastic member, so that the positioning protrusion engages with the first groove, and the card tray is in an extended state. From the above, it can be seen that with this structure, the user can install and remove the card tray simply by applying force to the card tray, without the need for an ejector pin or similar tool, making it easier to remove the card tray in this embodiment.

All other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative efforts fall within the scope of protection of the present application.

[0012] The terms "first," "second," etc. in the specification and claims of this application are intended to distinguish between similar objects and are not intended to describe a particular order or sequence. It is to be understood that terms so used are interchangeable where appropriate, so that embodiments of this application may be performed in orders other than those illustrated or described herein. Note that "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the related objects.

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the card tray assembly and electronic device according to the embodiments of the present application will be described in detail with reference to specific embodiments and application scenarios in conjunction with the drawings.

[0014] 1 to 16, an embodiment of the present application discloses a card tray assembly, which is a part of the electronic device and can support a card of the electronic device, and can be installed in a card tray hole installed in a housing 700 of the electronic device. The card tray assembly includes a positioning tube 100, a card tray 200, and a telescopic assembly, and the positioning tube 100 can be fixed and stationary, while the card tray 200 and the telescopic assembly can both telescope.

[0015] The positioning tube 100 is provided with a first fitting groove 110, a second fitting groove 120, and a first guide slope 130. The first guide slope 130 may have an inclination angle with respect to the extension and retraction direction of the card tray 200, and the inner surface of the first fitting groove 110 is connected to the inner surface of the second fitting groove 120 via the first guide slope 130. Optionally, the depth of the first fitting groove 110 in the extension and retraction direction of the card tray 200 is greater than the depth of the second fitting groove 120 in the extension and retraction direction of the card tray 200. The first fitting groove 110 may be a strip-shaped groove whose extension direction is parallel to the extension and retraction direction of the card tray 200, and the second fitting groove 120 may be a V-shaped groove. The number of the first mating groove 110, the second mating groove 120 and the first guide slope 130 may be one or at least two. When a plurality of the first mating grooves 110, the second mating grooves 120 and the first guide slopes 130 are installed, the first mating grooves 110 and the second mating grooves 120 are alternately arranged along the circumferential direction of the positioning tube 100, and any adjacent first mating grooves 110 and second mating grooves 120 are connected via the first guide slope 130.

[0016] The card tray 200 is provided with an operating portion 210, and when the card tray 200 receives an operating force from a user, the card tray 200 moves, and the operating portion 210 contacts the telescopic assembly and applies an operating force to the telescopic assembly, thereby moving the telescopic assembly. Optionally, the telescopic assembly may be installed on one side of the portion of the card tray 200 for placing a card, thereby utilizing the lateral space of the card tray 200 to position the telescopic assembly. The card tray assembly may further include a card holder 600, which may have a circuit area installed in it. A card on the card tray 200 can be fitted into the circuit area, thereby realizing a communication connection between the card and a circuit board of an electronic device.

[0017] The telescopic assembly includes a telescopic positioning member 300 and an elastic member 400. The telescopic positioning member 300 is movably installed on the positioning tube 100, and at least a portion of the telescopic positioning member 300 is located within the positioning tube 100. The telescopic positioning member 300 is provided with a positioning protrusion 310, which is installed on the outer circumferential surface of the telescopic positioning member 300 and may protrude from the outer circumferential surface. One end of the elastic member 400 is connected to the telescopic positioning member 300, and the other end of the elastic member 400 is a fixed end. Optionally, the elastic member 400 may be a spring, and the extension direction of the elastic member 400 may be parallel to the extension direction of the card tray 200.

[0018] The engagement of the positioning protrusion 310 with the first inclined guide surface 130 causes the acting portion 210 and the elastic member 400 to drive the telescopic positioning member 300 to rotate between the first position and the second position. That is, when the acting portion 210 applies an acting force to the telescopic positioning member 300, the elastic member 400 simultaneously applies an acting force to the telescopic positioning member 300. At this time, when the positioning protrusion 310 engages with the first inclined guide surface 130, the acting force applied by the acting portion 210 and the elastic member 400 in the opposite direction to that applied by both the acting portion 210 and the elastic member 400 causes the telescopic positioning member 300 to rotate between the first position and the second position, thereby switching between a state in which it engages with the first engaging groove 110 and a state in which it engages with the second engaging groove 120.

[0019] When the extendable positioning member 300 is in the first position, the positioning protrusion 310 is positionally engaged with the first engaging groove 110, and the card tray 200 is in an extended state, where the extended state means that at least a portion of the card tray 200 is located outside the housing 700, and in this state, a user can remove a card on the card tray 200 or attach a card to the card tray 200. When the extendable positioning member 300 is in the second position, the positioning protrusion 310 is positionally engaged with the second engaging groove 120, and the card tray 200 is in a retracted state, where the retracted state means that the card tray 200 is located within the housing 700.

[0020] In the embodiment of the present application, the expandable positioning member 300 is provided with a positioning protrusion 310 that can be fitted into the first fitting groove 110 and the second fitting groove 120 for position restriction. When a user applies force to the card tray 200, the action portion 210 of the card tray 200 and the elastic member 400 both apply force to the expandable positioning member 300. When the force applied by the acting portion 210 to the expandable positioning member 300 is greater, the expandable positioning member 300 moves, causing the positioning protrusion 310 to gradually disengage from the first fitting groove 110 and engage with the first inclined guide surface 130. The elastic member 400 then cooperates to drive the expandable positioning member 300 to rotate, causing the positioning protrusion 310 to engage with the second fitting groove 120. At this time, the card tray 200 is in a retracted state. When the user presses the card tray 200 again, the expandable positioning member 300 moves, causing the positioning protrusion 310 to gradually disengage from the second fitting groove 120 and engage with the first inclined guide surface 130. The elastic member 400 then cooperates to drive the expandable positioning member 300 to rotate, causing the positioning protrusion 310 to engage with the first fitting groove 110. At this time, the card tray 200 is in an extended state. As can be seen from the above, after adopting such a structure, the user can install and remove the card tray 200 simply by applying force to the card tray 200, without needing an ejection pin or similar tool, and therefore, in this embodiment, it is easier to remove the card tray 200.

[0021] In a further alternative embodiment, the telescopic assembly further includes a telescopic drive member 500, which is movably installed on the positioning tube 100, at least a portion of the telescopic drive member 500 being located within the positioning tube 100, and one end of the telescopic positioning member 300 remote from the elastic member 400 may be located within the telescopic drive member 500, the acting portion 210 facing the end face of the telescopic drive member 500, and a second guide slope 510 being provided on the telescopic drive member 500, the first guide slope 130 and the second guide slope 510 both being located on the same side of the positioning protrusion 310, and both being able to simultaneously engage with the positioning protrusion 310. Optionally, the second guide slope 510 may include a plurality of V-shaped surfaces arranged in a circumferential direction of the telescopic drive member 500 and connected in sequence, and the second guide slope 510 may always engage with the positioning protrusion 310. The engagement of the positioning protrusion 310 with the first guide inclined surface 130 and the second guide inclined surface 510 causes the action portion 210 and the elastic member 400 to drive the expandable positioning member 300 to rotate between the first position and the second position.

[0022] In order to more reliably restrict the rotation of the telescopic driving member 500, one or more guide protrusions 520 may be installed on the outer circumferential surface of the telescopic driving member 500, and the guide protrusions 520 may be fitted into the first fitting groove 110, thereby restricting the rotation of the telescopic driving member 500 through the first fitting groove 110.

[0023] When the card tray 200 is in the extended state, the positioning protrusion 310 fits into the first fitting groove 110. When the user presses the card tray 200 to apply an acting force to the telescopic driving member 500 via the acting part 210, as shown in FIG. 4, the positioning protrusion 310 gradually moves away from the bottom surface of the first fitting groove 110 until the positioning protrusion 310 reaches a state where it is completely disengaged from the first fitting groove 110 as shown in FIG. 5. At this time, the first fitting groove 110 no longer regulates the position of the telescopic positioning member 300, and the second guide slope 510 still fits into the positioning protrusion 310. At the same time, the elastic member 400 applies an acting force to the telescopic positioning member 300. 6, the user no longer presses the card tray 200, and the elastic member 400 drives the expandable positioning member 300 and the expandable driving member 500 to move along the extension direction of the card tray 200, so that the positioning protrusion 310 shown in FIG. 7 reaches a state where it engages with the first guide slope 130. Due to the action of the elastic member 400, the expandable positioning member 300 continues to rotate, so that it engages with the second engaging groove 120, i.e., reaches the state shown in FIG. 8. Due to the restricting action of the second engaging groove 120, the elastic member 400 no longer applies force to the card tray 200, and the card tray 200 can be maintained in the retracted state.

[0024] When the user needs to eject the card tray 200, he or she presses the card tray 200 in the same way, thereby exerting an acting force on the telescopic driving member 500 via the acting part 210, so that the positioning protrusion 310 gradually moves away from the bottom surface of the second fitting groove 120 until the positioning protrusion 310 reaches the state of being completely released from the second fitting groove 120 as shown in FIG. 9, at this time the second fitting groove 120 no longer regulates the position of the telescopic positioning member 300, the second guide slope 510 still fits with the positioning protrusion 310, and at the same time the elastic member 400 exerts an acting force on the telescopic positioning member 300, so that the telescopic positioning member 300 rotates to the state shown in FIG. 10, at this time the user can 11, the positioning protrusion 310 engages with the first inclined guide surface 130. Then, under the action of the elastic member 400, the expandable positioning member 300 continues to rotate, gradually entering the first engaging groove 110, i.e., the state shown in FIG. 12, until the positioning protrusion 310 engages with the bottom surface of the first engaging groove 110. Then, due to the restricting action of the first engaging groove 110, the elastic member 400 no longer applies force to the card tray 200, and the card tray 200 can be maintained in the extended state.

[0025] Compared with the case where the operating part 210 directly applies an acting force to the telescopic positioning member 300, after the telescopic driving member 500 is added, the telescopic driving member 500 can apply an acting force to the telescopic positioning member 300 via the second inclined guide surface 510, which, in cooperation with the elastic member 400, more reliably drives the rotation of the telescopic positioning member 300. There is almost no chance of the telescopic positioning member 300 being unable to rotate reliably after being separated from the first inclined guide surface 130. Therefore, this embodiment makes it easier and faster for users to remove and install the card tray 200.

[0026] When the positioning protrusion 310 engages with the second engaging groove 120, the elastic member 400 no longer applies force to the card tray 200. At this time, the friction between the card tray 200 and a member such as the housing 700 can hold the card tray 200 in the retracted state. However, this friction must not be too large, which can result in a problem of the card tray 200 not being reliably held in the retracted state. To solve this problem, the card holder 600 may be provided with a first locking portion 610, and the card tray 200 may be provided with a second locking portion 220. When the extendable positioning member 300 is in the second position, the first locking portion 610 engages with the second locking portion 220 to restrict positioning. Optionally, one of the first locking portion 610 and the second locking portion 220 may be a protrusion and the other a groove, thereby achieving position restriction with a simple structure. When the user no longer applies force to the card tray 200, and the elastic member 400 also no longer applies force to the card tray 200, the first locking portion 610 can engage with the second locking portion 220 to restrict positioning, thereby preventing the position of the card tray 200 from changing and reliably maintaining the retracted state. When the user wants to remove the card tray 200, the force applied by the user is sufficient to overcome the force between the first locking portion 610 and the second locking portion 220, thereby releasing the engagement between the first locking portion 610 and the second locking portion 220, allowing subsequent operations to be performed.

[0027] Alternatively, the entire telescopic assembly may be located on one side of the card holder 600, but in order to fully utilize the space around the card holder 600, the telescopic assembly and the card holder 600 may be at least partially overlapped in a direction perpendicular to the plane on which the card tray 200 is located, i.e., the orthogonal projection of the card holder 600 at least partially overlaps the orthogonal projection of the telescopic assembly in the direction perpendicular to the plane on which the card tray 200 is located. By installing them in this manner, the space above or below the card holder 600 can be fully utilized, the extra space occupied by the telescopic assembly can be reduced, and the structure of the entire card tray assembly can be made more compact.

[0028] In addition to using the card holder 600 to restrict the position of the card tray 200 and securely maintain it in the retracted state, the telescopic positioning member 300 can also be used to restrict the position of the card tray 200 and securely maintain it in the retracted state. As shown in Figures 17 to 19, the telescopic positioning member 300 is provided with a third locking portion 320 and a fourth locking portion 230, and when the telescopic positioning member 300 is in the second position, the third locking portion 320 is engaged with the fourth locking portion 230. When the telescopic positioning member 300 is in the second position, the second engaging groove 120 restricts the position of the telescopic positioning member 300. Therefore, when the third locking portion 320 is engaged with the fourth locking portion 230, the card tray 200 and the telescopic positioning member 300 remain substantially stationary relative to each other, thereby securely maintaining the card tray 200 in the retracted state.

[0029] In contrast, when the card holder 600 is used to restrict the position of the card tray 200, the first locking part 610 and the second locking part 220 may be installed in the space between the card holder 600 and the card tray 200, making the structure of the card tray assembly more compact. When the expandable positioning member 300 is used to restrict the position of the card tray 200, once the position of the expandable positioning member 300 changes as the user presses the card tray 200, the third locking part 320 and the fourth locking part 230 quickly release the engagement, allowing subsequent operations to be performed. Therefore, with this solution, the user does not need to exert force to press the card tray 200 to release the position restriction engagement, and the user's operations on the card tray 200 are more consistent.

[0030] The third locking portion 320 may be installed separately from the positioning protrusion 310. However, this installation makes it easier for the third locking portion 320 to interfere with the engagement between the telescopic positioning member 300 and the positioning tube 100. Therefore, in another embodiment, the third locking portion 320 is installed integrally with the positioning protrusion 310 and protrudes from the outer circumferential surface of the positioning tube 100. In other words, the third locking portion 320 is installed stacked on one side of the positioning protrusion 310 away from the center line of the telescopic positioning member 300. This embodiment, on the one hand, prevents the third locking portion 320 from interfering with the engagement between the telescopic positioning member 300 and the positioning tube 100. On the other hand, the overlapping installation of the positioning protrusion 310 and the third locking portion 320 can compensate for the distance between the telescopic positioning member 300 and the card tray 200, making it easier to achieve position-controlled engagement between the third locking portion 320 and the card tray 200.

[0031] When the third locking portion 320 is integrally installed with the positioning protrusion 310, the third locking portion 320 protrudes from the outer circumferential surface of the positioning tube 100. Therefore, to avoid the third locking portion 320, a recess 740 may be installed on the housing 700 of the electronic device. This recess 740 may be an escape groove, which can provide a movement space for the third locking portion 320.

[0032] Alternatively, when the telescopic positioning member 300 is in the second position, the plane on which the third locking portion 320 is located may be inclined relative to the plane on which the card tray 200 is located, or when the telescopic positioning member 300 is in the second position, the plane on which the third locking portion 320 is located is parallel to the plane on which the card tray 200 is located. In the latter embodiment, when the telescopic positioning member 300 is in the second position, the third locking portion 320 protrudes relatively little from the card tray 200 in a direction perpendicular to the card tray 200. If the thickness of the third locking portion 320 is equal to or less than the thickness of the card tray 200, no part of the third locking portion 320 protrudes from the card tray 200, and other components can be easily disposed near the third locking portion 320. Furthermore, optionally, when the telescopic positioning member 300 is in the first position, the angle between the plane on which the third locking portion 320 is located and the plane on which the card tray 200 is located may be 45° or other angles, and the embodiments of the present application are not limited thereto.

[0033] One of the third locking portion 320 and the fourth locking portion 230 is a protrusion, and the other is a groove, thereby realizing position regulation with a simple structure. Optionally, the card tray 200 has a first surface 240 and a second surface facing each other, and a side surface 250 connecting the first surface 240 and the second surface, and the fourth locking portion 230 is a locking groove, and the telescopic positioning member 300 can rotate in a single direction, so that the third locking portion 320 penetrates the locking groove during the process of rotating the telescopic positioning member 300 between the first position and the second position. The bottom surface of the locking groove may be curved, for example, arc-shaped. However, because such a locking groove is difficult to process, the bottom surface of the locking groove may be flat, and this bottom surface is connected to the first surface 240 and the second surface respectively. When the telescopic positioning member 300 is in the second position, there is a gap between the third locking portion 320 and the bottom surface. This gap can prevent interference between the card tray 200 and the third locking portion 320, thereby allowing the telescopic positioning member 300 to rotate more smoothly.

[0034] The bottom surface of the locking groove may be inclined, but this not only makes it difficult to machine the locking groove, but also leaves a relatively large gap between the bottom surface and the third locking portion 320, reducing the structural strength of the card tray 200. To solve these problems, the bottom surface of the locking groove may be perpendicular to the plane on which the card tray 200 is located, making it easier to machine the locking groove, and at the same time, the gap between any position on the bottom surface and the third locking portion 320 may be set within a relatively small range, thereby improving the structural strength of the card tray 200.

[0035] The positioning tube 100, the telescopic positioning member 300, the elastic member 400 and the telescopic driving member 500 may be installed in one set or two sets, and these two sets of the positioning tube 100, the telescopic positioning member 300, the elastic member 400 and the telescopic driving member 500 are respectively located on both sides of the card tray 200, thereby applying a more balanced force to the card tray 200 and preventing distortion of the card tray 200 during the ejection process.

[0036] The embodiments of the present application further disclose an electronic device, which includes a housing 700 and a card tray assembly, wherein the housing 700 has a card tray hole and the card tray assembly is installed in the card tray hole, and the card tray assembly is the card tray assembly described in any of the above embodiments. Optionally, the positioning tube 100 may be installed separately from or integral with the housing 700, and the embodiments of the present application are not limited thereto. Optionally, a first pillar 330 is provided on the telescopic positioning member 300, and a second pillar 750 is provided on the housing 700. One end of the elastic member 400 is fitted into the first pillar 330, and the other end of the elastic member 400 is fitted into the second pillar 750, thereby completing the installation of the elastic member 400.

[0037] The card tray hole may be configured as a fully communicating hole that simultaneously accommodates each part of the card tray assembly. Therefore, the size of the card tray hole may be relatively large, resulting in a relatively low structural strength of the housing 700. In another alternative embodiment, the card tray hole may include a first receiving hole 710, a second receiving hole 720, and a third receiving hole 730. The axis of the first receiving hole 710 is parallel to the axis of the second receiving hole 720, and the first receiving hole 710 communicates with the second receiving hole 720 via the third receiving hole 730. The card tray 200 includes a mounting portion and a positioning end 260. The mounting portion is used to mount a card. The positioning end 260 is located at one end of the mounting portion. The positioning end 260 is a strip-shaped portion, and the operating portion 210 is provided at one end of the positioning end 260 along its extension direction. When the telescopic positioning member 300 is in the second position, the positioning end 260 is located within the third accommodating hole 730, the mounting portion is fitted into the first accommodating hole 710, and the operating portion 210 faces the second accommodating hole 720. In this embodiment, since a portion of the structure of the housing 700 exists between the first accommodating hole 710 and the second accommodating hole 720, the sizes of the first accommodating hole 710, the second accommodating hole 720, and the third accommodating hole 730 are all relatively small, and the structural strength of the housing 700 is further increased.
