For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0040] The following Figures 1 to 4 describes an electronic device according to an embodiment of the present application.

[0041] As Figure 1 and Figure 2 shown, the electronic device according to the embodiment of the present application includes: a housing, a card tray 1, a transmission member 4, and a grounding member 3.

[0042] A card slot 2 is provided on one side of the housing. The card slot 2 is adapted to the card tray 1. The card tray 1 is detachably disposed in the card slot 2. That is to say, the card tray 1 can move relative to the card slot 2. The card tray 1 can be inserted into the card slot 2 or separated from the card slot 2.

[0043] Both the transmission member 4 and the grounding member 3 are disposed in the card slot 2.

[0044] Wherein, when the card tray 1 is in contact with the transmission member 4 and moves relative to the card slot 2, the transmission member 4 drives the grounding member 3 to move towards the card tray 1 to abut against the card tray 1, or drives the grounding member 3 away from the card tray 1 to separate from the card tray 1.

[0045] It should be noted that when the card tray 1 is inserted into the card slot 2, a grounding point is provided at one end of the card tray 1 close to the slot wall of the card slot 2. Among them, the number of grounding points can be one or two.

[0046] Among them, the grounding point can be located on one side of the card tray 1 facing the slot top of the card slot 2, or on one side of the card tray 1 facing the slot bottom of the card slot 2.

[0047] In the embodiment of the present application, during the process of the card tray 1 moving towards the slot wall of the card slot 2, one end of the card tray 1 facing the slot wall of the card slot 2 will contact the transmission member 4. At this time, the transmission member 4 can drive the grounding member 3 to move towards the card tray 1 to abut against the card tray 1, thereby removing the static electricity on the card tray 1 and ensuring the grounding reliability of the card tray 1; or, during the process of the card tray 1 moving away from the slot wall of the card slot 2, the transmission member 4 drives the grounding member 3 to move away from the card tray 1 to separate from the card tray 1, thereby realizing the smooth removal of the card tray 1.

[0048] It is understandable that the above-mentioned cato 1, grounding member 3 and transmission member 4 are all made of materials with good electrical conductivity. For example, the cato 1, grounding member 3 and transmission member 4 are made of copper.

[0049] In an alternative embodiment, as Figure 4 shown, the transmission member 4 includes a slider 41 and a gear assembly.

[0050] A tooth portion 42 is provided on one side of the slider 41 facing the gear assembly. The slider 41 is drivingly connected to one end of the gear assembly through the tooth portion 42, and the other end of the gear assembly is connected to the grounding member 3.

[0051] When the cato 1 moves relative to the card slot 2, the slider 41 has a first position and a second position relative to the card slot 2;

[0052] When the slider 41 is in the first position, the grounding member 3 abuts against the cato 1, and when the slider is in the second position, the grounding member 3 is separated from the cato 1.

[0053] Among them, the slider 41 can be a cuboid. During the process of the cato 1 moving towards the groove wall of the card slot 2, one end of the cato 1 facing the groove wall of the card slot 2 will contact the slider 41, and the slider 41 can be switched from the second position to the first position. At this time, the gear assembly can drive the grounding member 3 to move towards the cato 1 to abut against the cato 1; or, during the process of the cato 1 moving away from the groove wall of the card slot 2, the slider 41 can be switched from the first position to the second position, and the gear assembly drives the grounding member 3 to move away from the cato 1 to be separated from the cato 1.

[0054] In an alternative embodiment, as Figure 3 shown, the grounding member 3 includes a connecting column 33 and a grounding column 32. One end of the connecting column 33 is connected to the grounding column 32, and the other end of the connecting column 33 is connected to the other end of the gear assembly.

[0055] Driven by the gear assembly, the connecting column 33 rotates around its axis, the grounding column 32 can move relative to the connecting column 33, and one end of the grounding column 32 away from the connecting column 33 can abut against or be separated from the cato 1.

[0056] Among them, the connecting column 33 can be a solid circular column, the grounding column 32 is a hollow circular column, and the grounding column 32 can be sleeved on the outer side surface of the connecting column 33.

[0057] It should be noted that when the slider 41 switches from the second position to the first position, at this time, the gear assembly can drive the connecting column 33 to rotate clockwise around its axis, and the grounding column 32 moves towards the cartridge holder 1; or, during the process of the cartridge holder 1 moving away from the groove wall of the card slot 2, the slider 41 switches from the first position to the second position, at this time, the gear assembly can drive the connecting column 33 to rotate counterclockwise around its axis, and the grounding column 32 moves away from the cartridge holder 1.

[0058] In an alternative embodiment, the grounding member 3 further includes a guiding member 31. The grounding column 32 is threadedly connected to the outer side surface of the connecting column 33. A protruding portion 34 is provided on the outer side surface of the grounding column 32. The guiding member 31 is provided with a guide rail groove extending along its height direction, and the protruding portion 34 is located within the guide rail groove.

[0059] Wherein, an external thread is provided on the outer wall of the connecting column 33 along its axial direction. The external thread can be a left-handed thread or a right-handed thread. An internal thread is provided on the inner wall of the grounding column 32 along its axial direction. The internal thread can be a left-handed thread or a right-handed thread. The external thread and the internal thread have the same hand of helix, and the external thread and the internal thread are adapted to each other, whereby the grounding column 32 and the connecting column 33 achieve a screw fit.

[0060] The guiding member 31 can be a cylinder or a square body, etc. The shape of the guiding member 31 is not specifically limited, as long as the rotation of the grounding column 32 can be restricted by the guiding member 31. The guiding member 31 can be fixed in the card slot by means of adhesion, welding or screwing. For example, the two can be fixedly connected by a round rod. One end of the round rod is welded to the groove wall of the card slot 2, and the other end of the round rod is welded to the outer wall of the guiding member 31, and the guiding member 31 and the card slot 2 are fixedly connected through the round rod.

[0061] It can be understood that the guiding member 31 is provided with a guide rail groove extending along its height direction. The guide rail groove can be provided on the inner wall of the guiding member 31. The shape of the guide rail groove can be a long strip shape, and the number of the guide rail grooves can be one or more. In the case where the number of the guide rail grooves is multiple, the guide rail grooves are evenly distributed along the circumferential direction of the guiding member 31.

[0062] A protruding portion 34 is provided on the outer wall of the grounding column 32. The shape of the protruding portion 34 is adapted to the shape of the guide rail groove. The number of the protruding portions 34 can be the same as the number of the guide rail grooves, or multiple protruding portions 34 correspond to one guide rail groove.

[0063] It should be noted that the fit between the protruding portion 34 and the guide rail groove is a clearance fit, which facilitates the flexible movement of the grounding column 32.

[0064] The guiding member 31 is fixedly connected to the card slot 2. When the connecting column 33 rotates around its axis, since the protruding portion 34 is embedded in the guide rail groove, the guide rail groove restricts the rotation of the grounding column 32, and the grounding column 32 can only move up and down along its axis.

[0065] The following is a detailed description of the usage process of the electronic device.

[0066] When the card tray 1 is inserted into the card slot 2, as the card tray 1 moves towards the slot wall of the card slot 2, the slider 41 switches from the second position to the first position. At this time, the gear assembly can drive the connecting column 33 to rotate clockwise around its axis, and the grounding column 32 screws out relative to the connecting column 33 and moves towards the card tray 1 along its axis direction. Finally, the bottom of the grounding column 32 abuts against the grounding point on the card tray 1. When the card tray 1 is removed from the card slot 2, the card tray 1 moves away from the bottom of the card slot 2, and the slider 41 switches from the first position to the second position. At this time, the gear assembly can drive the connecting column 33 to rotate counterclockwise around its axis, and the grounding column 32 screws into the connecting column 33 and moves away from the card tray 1 along its axis direction. Finally, the bottom of the grounding column 32 is separated from the grounding point on the card tray 1, thereby realizing the smooth removal of the card tray 1.

[0067] In an alternative embodiment, the guiding member 31 is a sleeve, and the sleeve is sleeved on a part of the grounding column 32.

[0068] Specifically, the guiding member 31 is a sleeve, and the grounding column 32 is also a hollow cylinder. The sleeve and the grounding column 32 are coaxially arranged. The inner diameter of the sleeve is adapted to the outer diameter of the grounding column 32, and the length of the sleeve is equivalent to the length of the grounding column 32. The sleeve and the grounding column 32 are in clearance fit, facilitating the flexible movement of the grounding column 32.

[0069] It should be noted that the guide rail is provided on the inner side surface of the sleeve; alternatively, the guide rail penetrates through the opposite side surfaces of the sleeve.

[0070] The sleeve is fixedly connected to the card slot 2. When the connecting column 33 rotates around its axis, since the convex portion is embedded in the guide rail groove, the guide rail groove restricts the rotation of the grounding column 32, and the grounding column 32 can move up and down flexibly along its axis direction.

[0071] In an alternative embodiment, the gear assembly includes a second gear 43, a third gear 45, and a linkage shaft 44;

[0072] One end of the linkage shaft 44 is connected to the end face of the second gear 43, and the other end of the linkage shaft 44 is connected to the end face of the third gear 45. The slider 41 is meshed and connected to the second gear 43 through the tooth portion 42, and the other end of the connecting column 33 is connected to the end face of the third gear 45.

[0073] Specifically, the second gear 43 and the third gear 45 are arranged at opposite ends of the linkage shaft 44, and the second gear 43 and the third gear 45 are arranged opposite to each other. One end of the linkage shaft 44 can be welded to one end face of the second gear 43, and the linkage shaft 44 can also be fixedly connected to the second gear 43 through a key; the other end of the linkage shaft 44 can be welded to one end face of the third gear 45, and the linkage shaft 44 can also be fixedly connected to the third gear 45 through a key.

[0074] Among them, the sizes of the second gear 43 and the third gear 45 can be the same or different, and are specifically set according to the actual usage situation.

[0075] It should be noted that during the process of the slider 41 moving towards or away from the groove wall of the card slot 2, the slider 41 drives the second gear 43 to rotate through the tooth portion 42, the second gear 43 drives the third gear 45 to rotate, the third gear 45 drives the connecting column 33 to rotate around its axis, and the grounding column 32 is screwed into or out of the connecting column 33, thereby realizing the abutment or separation of the bottom of the grounding column 32 from the grounding point on the card holder 1.

[0076] In the embodiment of the present application, the accuracy of rotation is improved through gear transmission, and further the stability of the grounding column 32 moving towards or away from the card holder 1 is improved.

[0077] In an alternative embodiment, the gear assembly further includes a first gear 46, the end face of the first gear 46 is connected to the other end of the connecting column 33, and the third gear 45 is meshed and connected to the first gear 46.

[0078] It should be noted that during the process of the slider 41 moving towards or away from the groove wall of the card slot 2, the slider 41 drives the second gear 43 to rotate through the tooth portion 42, the second gear 43 drives the third gear 45 to rotate, the third gear 45 drives the first gear 46 to rotate, the first gear 46 drives the connecting column 33 to rotate around its axis, and the grounding column 32 is screwed into or out of the connecting column 33, thereby realizing the abutment or separation of the end of the grounding column 32 from the grounding point on the card holder 1.

[0079] In an alternative embodiment, the transmission member further includes an elastic member, one end of the elastic member is connected to one end of the slider 41 facing the groove wall of the card slot 2, and the other end of the elastic member is connected to the groove wall of the card slot 2.

[0080] Among them, the elastic member can be a cylindrical spring, one end of the elastic member can be connected to one end of the slider 41 facing the groove wall of the card slot 2 by welding, and the other end of the elastic member can be connected to the groove wall of the card slot 2 by welding.

[0081] The following details the usage process of the electronic device.

[0082] When the card holder 1 is inserted into the card slot 2, after one side of the card holder 1 facing the slot wall of the card slot 2 abuts against the slider 41, under the thrust of the card holder 1, the slider 41 moves towards the bottom of the card slot 2. The slider 41 drives the second gear 43 to rotate through the tooth part 42. The second gear 43 drives the third gear 45 to rotate. The third gear 45 drives the first gear 46 to rotate. The first gear 46 drives the connecting column 33 to rotate around its axis. The grounding column 32 screws out relative to the connecting column 33, and the grounding column 32 moves towards the card holder 1 along its axis. Finally, the end of the grounding column 32 abuts against the grounding point on the card holder 1, thereby removing the static electricity on the card holder 1 and ensuring the grounding reliability of the card holder 1.

[0083] When the card holder 1 is taken out of the card slot 2, the card holder 1 moves in a direction away from the bottom of the card slot 2. The restoring force of the elastic member pushes the slider 41 to move away from the bottom of the card slot 2. The slider 41 drives the second gear 43 to rotate through the tooth part 42. The second gear 43 drives the third gear 45 to rotate. The third gear 45 drives the first gear 46 to rotate. The first gear 46 drives the connecting column 33 to rotate around its axis. The grounding column 32 screws into the connecting column 33 and moves away from the card holder 1 along its axis. Finally, the end of the grounding column 32 is separated from the grounding point on the card holder 1, thereby realizing the smooth removal of the card holder 1.

[0084] In an optional embodiment, in order to facilitate the installation of the linkage shaft 44, the electronic device further includes a bearing. The bearing is arranged in the card slot 2, and the linkage shaft 44 is inserted into the bearing.

[0085] Specifically, the bearing can be a pedestal bearing. The bearing is detachably arranged in the card slot 2, and the bearing is coaxially arranged with the linkage shaft 44.

[0086] In an optional embodiment, the end face of the first gear 46 can abut against the top end of the sleeve.

[0087] Specifically, the sleeve is fixedly connected in the card slot 2. The connecting column 33 is connected to one end face of the first gear 46. The grounding column 32 is in screw fit with the connecting column 33. After the grounding column 32 and the connecting column 33 are inserted into the sleeve, the end face of the first gear 46 connected to the connecting column 33 abuts against the top end of the sleeve. Thus, one end face of the sleeve provides an assembly basis for the first gear 46, realizing the axial fixation of the first gear 46 and the connecting column 33.

[0088] In an optional embodiment, the tooth part 42 includes a plurality of columns arranged at intervals along the sliding direction of the slider 41.

[0089] Specifically, the tooth part 42 includes a plurality of columns arranged at intervals along the sliding direction of the slider 41. The plurality of columns are evenly distributed, and the shape of the columns is not specifically limited as long as it is convenient for the tooth part 42 and the second gear 43 to be rotatably connected.

[0090] In an alternative embodiment, a sliding groove is provided at the bottom of the card slot 2, and the sliding groove is adapted to the slider 41, and the slider 41 is disposed in the sliding groove.

[0091] Specifically, the slider 41 may be a cuboid, the depth of the sliding groove is less than the height of the slider 41, the sliding groove is adapted to the slider 41, and after the slider 41 is placed in the sliding groove, a part of the slider 41 is located outside the sliding groove, facilitating the card holder 1 to abut against the slider 41.

[0092] During the process of the slider 41 moving towards or away from the groove wall of the card slot 2, the sliding groove defines the moving direction of the slider 41, which can ensure that the moving direction of the slider 41 is consistent with the moving direction of the card holder, ensuring that the tooth portion 42 can be meshed with the second gear 43, further ensuring that the grounding post 32 can be screwed out or screwed into the connecting post 33, so that the grounding post 32 can abut against or separate from the grounding point on the card holder 1, improving the stability of the electronic device.

[0093] In an alternative embodiment, the electronic device is a mobile phone, a tablet computer, a wearable device, a digital camera or a navigator.

[0094] Taking the electronic device as a mobile phone as an example, the assembly and disassembly processes of the electronic device will be specifically described below.

[0095] As Figures 1 to 4 shown, two grounding points are provided on the top surface of the card holder 1, and the two grounding points are symmetrically distributed about the center line of the card holder 1. The number of grounding members 3 is two, and the two grounding members 3 are symmetrically distributed about the center line of the card slot 2. The number of transmission members 4 is also two, and the two transmission members 4 are symmetrically distributed about the center line of the card holder 1. The number of sliding grooves is also two, and the two sliding grooves are symmetrically distributed about the center line of the card holder 1.

[0096] When the card holder 1 is inserted into the card slot 2, after one side of the card holder 1 facing the groove wall of the card slot 2 contacts the slider 41, under the thrust of the card holder 1, the slider 41 located in the sliding groove moves towards the groove wall of the card slot 2, the elastic member undergoes compressive deformation, the toothed column on the slider 41 drives the second gear 43 to rotate, the second gear 43 drives the third gear 45 to rotate, the third gear 45 drives the first gear 46 to rotate, the first gear 46 drives the connecting post 33 to rotate about its axis, the convex portion of the grounding post 32 is located in the guide groove of the sleeve, the grounding post 32 is screwed out relative to the connecting post 33 and moves towards the card holder 1 along its axis, and finally the end of the grounding post 32 abuts against the grounding point on the card holder 1, thereby removing the static electricity on the card holder 1 and ensuring the grounding reliability of the card holder 1.

[0097] When the card holder 1 is taken out of the card slot 2, the card holder 1 moves away from the slot wall of the card slot 2. The resilience of the elastic member pushes the slider 41 in the chute to move away from the slot wall of the card slot 2. The toothed cylinder on the slider 41 drives the second gear 43 to rotate. The second gear 43 drives the third gear 45 to rotate. The third gear 45 drives the first gear 46 to rotate. The first gear 46 drives the connecting column 33 to rotate around its axis. The protruding portion of the grounding column 32 is located in the guide groove of the sleeve. The grounding column 32 is screwed into the connecting column 33 and moves away from the card holder 1 along its axis. Finally, the end of the grounding column 32 is separated from the grounding point on the card holder 1, thus realizing the smooth removal of the card holder 1.
