Description

Technical Field

[0001] This application belongs to the technical field of electrical accessory devices, and particularly relates to a mobile socket capable of reducing thickness. Background Art

[0002] A socket refers to a base with one or more circuit wiring insertion ports, through which various wirings can be inserted, facilitating connection to other circuits. The main classifications of sockets are fixed and mobile. A fixed socket is a socket used for connection to fixed wiring, such as a socket installed on a wall in an indoor environment. A mobile socket is connected to a flexible cable or integrated with a flexible cable, and is a socket that can be easily transferred from one place to another when connected to a power supply, such as a commonly used movable power strip.

[0003] For mobile sockets, in order to facilitate portability when going out, they are gradually developing towards being lightweight and easy to store. However, the specifications of electrical plugs are set according to industry standards, that is, the length of the pins of electrical plugs is fixed and cannot be changed after leaving the factory. Therefore, the minimum thickness of a mobile socket is limited by the depth of the slots into which the power supply plugs are inserted. For example, the minimum thickness of sockets applicable to Chinese, American, Japanese standards, etc. is about 24.5 mm. It can be seen that the thickness dimension of mobile sockets is limited and cannot be made smaller or thinner, which has an adverse impact on the portability of mobile sockets. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a mobile socket to solve the technical problem that the thickness of the existing mobile socket is limited and cannot be made thinner, which affects portability.

[0005] To achieve the above purpose, the technical solution adopted in this application is: providing a mobile socket, including:

[0006] A housing with an opening;

[0007] A lifting platform disposed on the opening of the housing, and the lifting platform has a set of jacks into which the pins of the power supply plug are inserted;

[0008] A first elastic member disposed in the housing and connected to the lifting platform, and the first elastic member drives the lifting platform to rise from the opening of the housing;

[0009] A key lock disposed on the housing, and the key lock is used to lock the lifting platform that has sunk into the opening.

[0010] The beneficial effects of the mobile socket provided by this application are as follows: Compared with the prior art, the mobile socket of this application redesigned the plugging part of the electrical plug. There is a lifting platform on the socket, and a jack group for inserting the pins of the power supply plug is provided on the lifting platform. The first elastic member inside the housing drives the lifting platform to rise to meet the pin length requirements of the electrical plug, enabling the pins of the electrical plug to be completely inserted into the jacks of the socket and ensuring the stability of the electrical connection.

[0011] The mobile socket of this application is also provided with a key lock, which is used to lock the lifting platform sunk in the opening of the housing. The lifting platform is pressed down by hand and stored in the housing, so that the upper surface of the lifting platform can be flush with the surface of the housing, making the thickness of the mobile socket smaller and thinner, facilitating storage and carrying. When in need of use, the user operates the key lock to unlock the lifting platform to release it, enabling the lifting platform to rise and protrude from the housing, facilitating the complete insertion and normal use of the pins of the electrical plug, and effectively ensuring the applicability of the mobile socket.

[0012] Improve the structure of the lifting platform. A step protruding outward is provided on the outer periphery of the lifting platform, and the step is used for snap-fitting with the opening of the housing or the key lock. The key lock is snap-fitted with the step to fix the storage position of the lifting platform, and the structure on the housing opening is snap-fitted with the step of the lifting platform to limit the protruding position of the lifting platform and prevent the lifting platform from coming out.

[0013] In one embodiment, a surrounding frame is provided on the housing around the opening, and the surrounding frame is snap-fitted with the step on the lifting platform rising from the opening. The surrounding frame on the housing opening is snap-fitted with the step on the outer periphery of the lifting platform to limit the protruding position of the lifting platform on the housing and prevent the lifting platform from coming out of the housing.

[0014] Improve the structure of the key lock. The key lock includes a second elastic member and a buckle strip that can be buckled on the step. One end of the second elastic member is fixed inside the housing, and the other end of the second elastic member is connected to the buckle strip; when the lifting platform sinks into the opening of the housing, the second elastic member drives the buckle strip to be buckled on the step of the lifting platform. In this way, the acting force of the second elastic member makes the buckle strip move towards the lifting platform, keeping the buckle strip buckled on the step of the lifting platform. Only when the user operates the key lock, the buckle strip is pulled away from the step to achieve unlocking.

[0015] In one embodiment, the button lock further includes a dial for manual operation, and the dial is arranged on the buckle strip; a travel groove for restricting the movement track of the dial is formed on the housing, and the dial passes through the travel groove. In this way, a person's hand can operate the dial to synchronously drive the buckle strip to move within the range of the travel groove, so that the buckle strip can be moved away from the step of the lifting table, realizing the unlocking operation of the lifting table.

[0016] In one embodiment, the button lock includes a pair of the second elastic members, and the dial is arranged in the middle of the buckle strip; one ends of the pair of second elastic members are respectively arranged near the two ends of the buckle strip, and the other ends of the pair of second elastic members extend parallel in the same direction and are fixed inside the housing. The use of a pair of second elastic members that move synchronously can improve the pushing force on the buckle strip, ensure that the buckle strip and the step can be buckled in place, and further improve the locking effect of the button lock.

[0017] In one embodiment, the button lock further includes a supporting plate arranged between the buckle strip and the dial, and the plate surface of the supporting plate is in flat contact with the inner top wall of the housing to support the dial to keep passing through the travel groove. By using the supporting plate to support the dial, under the support of the supporting plate and the inner top wall of the housing, the dial can protrude from the opening of the housing when a person applies force, effectively improving the operation stability of the button lock.

[0018] In one embodiment, positioning notches are formed on the steps on at least one side of the lifting table, and at least one end of the supporting plate has a convex edge that can extend into the positioning notch, and the convex edge is in position cooperation with the positioning notch. In this way, by using the positioning notch on the lifting table and the convex edge on the supporting plate for fitting, the lifting table can be installed on the housing in a directional manner, thus playing a role in preventing incorrect installation.

[0019] Improve the structure of the first elastic member. The first elastic member is a spring or a folding elastic sheet, and a fixing seat matching the shape of the end of the first elastic member is arranged on the inner wall of the lifting table; one end of the first elastic member is fixed on the inner wall of the housing, and the other end of the first elastic member is fixed on the fixing seat. Use the acting force of the first elastic member to push the lifting table upward, or push down the lifting table by hand to make the first elastic member contract, so that the lifting table is reset.

[0020] In one embodiment, the first elastic member is arranged on the inner bottom wall of the housing and is located on the central axis of the housing; the fixing seat is arranged at the central part of the lifting table, and the jack group on the lifting table is arranged to avoid the fixing seat. In this way, the first elastic member is centered on the housing and is also connected to the central part of the lifting table, which is beneficial to improving the smoothness of the first elastic member pushing the lifting table upward and also improving the stability of the operation of a person pressing down the lifting table to reset.

[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0045] In order to reduce the thickness of a mobile socket, in the related art, an attempt has been made to provide a movable structure of a spring plus a gear at the part of the socket where the power supply plug is inserted, so that this part can achieve automatic lifting. However, this structure requires a re-design of the internal layout of the inserted part, making the whole movable structure complex, occupying a large internal space and increasing the production cost; moreover, since a gear is used for the movable fit, the sealing performance of the socket needs to be improved. Otherwise, if a small grain of sand gets stuck in the gear, the whole movable structure will not be able to operate. Therefore, such a movable structure is prone to failure and affects the service life of the socket.

[0046] Herein, an embodiment of the present application provides a novel mobile socket, which improves the structure of the socket for being inserted by an electric plug, enabling the inserted part inserted by the electric plug to perform a lifting movement. Under normal circumstances, the structure of this part sinks into the socket and is flush with the surface of the socket, making the socket thin and small, facilitating storage and carrying. When in use, unlock the structure of this part so that it can rise and protrude on the socket to match the pin length of the electric plug, facilitating the normal insertion of the electric plug for use, effectively solving the problem that the thickness of the traditional mobile socket is limited and cannot be made thin, which affects the portability. Now, a detailed description thereof will be given.

[0047] Please refer to Figure 1 、 Figure 2 and Figure 3 , the mobile socket includes a housing 1, a lifting platform 2, a first elastic member 3, and a key lock 4.

[0048] An opening 11 is formed on the housing 1, and this opening 11 is used for arranging the structure for the pins of the power supply plug to be inserted. The housing 1 has an accommodation space inside, which can be used for arranging internal electrical components.

[0049] The lifting platform 2 is arranged on the opening 11 of the above-mentioned housing 1. The lifting platform 2 is provided with a socket group 21 for the pins of the power supply plug to be inserted. There can be multiple and different types of the socket group 21, such as traditional two-socket and three-socket, etc. These sockets can be arranged individually, or the socket groups 21 of the two-socket and three-socket are arranged with overlapping positions. Multiple socket groups 21 can be arranged according to the surface area of the lifting platform 2, such as being arranged in a "pin" shape or matrix on the lifting platform 2. Thus, for the setting method and layout form of these socket groups 21 on the lifting platform 2, etc., they can be set according to the usage requirements, and no specific limitation is made here.

[0050] Such as Figure 3As shown in the figure, the first elastic member 3 is disposed inside the housing 1. The first elastic member 3 extends upward to the lifting platform 2 and is fixedly connected to the lifting platform 2. The first elastic member 3 is used to drive the lifting platform 2 to rise from the opening 11 of the housing 1, so that the hole depth in each jack group 21 can adapt to the pin length of the electrical plug, enabling the electrical plug to be normally plugged into the mobile socket for normal use.

[0051] The key lock 4 is used to lock the lifting platform 2 that sinks into the opening 11. The key lock 4 is disposed on the housing 1 and can preferably be disposed adjacent to the opening 11 on the housing 1, so that the key lock 4 can cooperate with the lifting platform 2 as a lock to restrict the lifting platform 2 within the opening 11, making the upper surface of the lifting platform 2 flush with the surface of the housing 1. This makes the thickness of the mobile socket less than the pin length of the electrical plug in the normal state, making the mobile socket thinner and lighter, and convenient for storage and carrying.

[0052] Compared with the prior art, the mobile socket provided by the embodiment of the present application re - designs the plug - in part of the electrical plug. The socket is provided with a lifting platform 2, and the lifting platform 2 is provided with a jack group 21 for inserting the pins of the electrical plug. The first elastic member 3 inside the housing 1 drives the lifting platform 2 to rise to meet the pin length requirement of the electrical plug, enabling the pins of the electrical plug to be completely inserted into the jacks of the socket, effectively ensuring the stability of the electrical connection.

[0053] The mobile socket of the present application is also provided with a key lock 4, which is used to lock the lifting platform 2 that sinks into the opening 11 of the housing 1. In practical applications, the lifting platform 2 can be manually pressed down so that the lifting platform 2 sinks into the opening 11 of the housing 1; then, the key lock 4 is used to lock it, thereby preventing the lifting platform 2 from bouncing up under the action of the first elastic member 3. In this way, the lifting platform 2 is stored in the housing 1, and the upper surface of the lifting platform 2 can be flush with the surface of the housing 1, so that the thickness of the mobile socket becomes smaller, thinner and lighter, and convenient for storage and carrying. When in need of use, the key lock 4 is manually operated to unlock the lifting platform 2 to release the lifting platform 2, enabling the lifting platform 2 to rise and protrude from the housing 1, facilitating the complete insertion and normal use of the pins of the electrical plug, effectively ensuring the applicability of the mobile socket.

[0054] Compared with the above - mentioned related technologies, the cooperation structure of the lifting platform 2 and the key lock 4 adopted by the mobile socket of the present application is simple and occupies little internal space. The first elastic member 3 inside the housing 1 can drive the lifting platform 2 to automatically rise to meet the pin plug - in requirement of the electrical plug. During storage, the lifting platform 2 can be directly pressed down by hand to return to its original position, and the key lock 4 is used to lock it, which is convenient for use. Since no gear - matching components are used, the requirement for sealing is low, effectively reducing the production difficulty and production cost.

[0055] It can be seen that, as can be understood from the above, for the lifting platform 2, there are at least two positions that need to be positioned. One is when the lifting platform 2 sinks into the opening 11 of the housing 1, and the storage position of the lifting platform 2 is locked by the button lock 4; the other is when the lifting platform 2 is driven to rise by the first elastic member 3, and the protruding position of the lifting platform 2 on the housing 1.

[0056] Herein, for the specific structure of the lifting platform 2, in an embodiment of the present application, please refer to Figure 3 , Figure 4 and Figure 5 . An outwardly protruding step 22 is provided on the outer periphery of the lifting platform 2, and the step 22 can be engaged with the structure on the opening 11 of the housing 1 or the button lock 4. The engagement of the button lock 4 with the step 22 is used to fix the storage position of the lifting platform 2, and the structure on the opening 11 of the housing 1 is engaged with the step 22 of the lifting platform 2 to limit the protruding position of the lifting platform 2 and prevent the lifting platform 2 from disengaging.

[0057] In this embodiment, the step 22 can be a complete convex ring provided around the outer periphery of the lifting platform 2, which is beneficial to the complete engagement with the structure on the opening 11 of the housing 1 and at the same time ensures the sealing performance of the opening 11 part of the mobile socket.

[0058] In other embodiments, the step 22 can also be a plurality of convex ribs distributed on the outer periphery of the lifting platform 2, and these convex ribs are at the same height on the circumferential wall of the lifting platform 2, so that when the lifting platform 2 rises, each convex rib can be synchronously engaged with the structure on the opening 11 of the housing 1, thereby ensuring the flatness of the lifting platform 2 after rising from the opening 11 of the housing 1.

[0059] For the mating structure between the opening 11 of the housing 1 and the lifting platform 2, in an embodiment of the present application, please refer to Figure 4 , Figure 5 and Figure 6 . A surrounding frame 12 is provided on the housing 1 around the opening 11, and the lifting platform 2 rises from the opening 11 under the action of the first elastic member 3 until the step 22 is engaged with the surrounding frame 12. Thus, the surrounding frame 12 on the opening 11 of the housing 1 is engaged with the step 22 on the outer periphery of the lifting platform 2 to limit the protruding position of the lifting platform 2 on the housing 1, thereby preventing the lifting platform 2 from disengaging from the housing 1.

[0060] In this embodiment, as Figure 6As shown, the surrounding frame 12 is disposed inside the housing 1 and is convexly arranged. The surrounding frame 12 can preferably be a convex frame around the outer periphery of the opening 11 of the housing 1. On the one hand, any part of the step 22 on the outer periphery of the lifting table 2 can be buckled with the surrounding frame 12, effectively preventing the lifting table 2 from coming off; on the other hand, setting the surrounding frame 12 on the opening 11 of the housing 1 is beneficial to improving the structural strength of the opening 11 part of the housing 1, preventing the opening 11 on the housing 1 from being easily deformed, and extending the service life of the housing 1.

[0061] For the mating structure of the key lock 4 with the lifting table 2, in an embodiment of the present application, please refer to Figure 4 、 Figure 5 and Figure 7 . The key lock 4 includes a second elastic member 41 and a buckle strip 42 that can be buckled on the step 22. One end of the second elastic member 41 is fixed inside the housing 1, and the other end of the second elastic member 41 is connected to the buckle strip 42.

[0062] When the lifting table 2 sinks into the opening 11 of the housing 1, the acting force of the second elastic member 41 drives the buckle strip 42 to move towards the lifting table 2, and keeps the buckle strip 42 buckled on the step 22 of the lifting table 2.

[0063] The second elastic member 41 can preferably be a spring. For the fixing structure of both ends of the second elastic member 41, in this embodiment, as Figure 7 shown, one end of the second elastic member 41 is fixed inside the housing 1. There is a convex fixing table 13 inside the housing 1, and one end of the second elastic member 41 is fixed on the fixing table 13. As Figure 2 shown, the other end of the second elastic member 41 is fixed on the buckle strip 42. There is a connecting ear 421 on the buckle strip 42, and the other end of the second elastic member 41 is fixed on the connecting ear 421.

[0064] In the normal state of the key lock 4, the acting force of the second elastic member 41 makes the buckle strip 42 keep moving towards the lifting table 2, so that the buckle strip 42 keeps buckled on the step 22 of the lifting table 2. When a person operates the key lock 4 by hand, the buckle strip 42 is only pulled away from the step 22 to achieve unlocking. When the person releases the key lock 4 by hand, the buckle strip 42 is reset under the acting force of the second elastic member 41 and abuts against the lifting table 2 again, and is buckled and matched with the step 22.

[0065] For the specific structure of the key lock 4, in an embodiment of the present application, please refer to Figure 3 and Figure 8 . The key lock 4 further includes a dial block 43 for manual operation, and the dial block 43 is arranged on the buckle strip 42. Preferably, the dial block 43 can also be integrally formed with the buckle strip 42 to ensure the structural strength.

[0066] A stroke groove 14 for restricting the movement track of the toggle block 43 is provided on the housing 1. The stroke groove 14 is arranged close to the opening 11 of the housing 1. The toggle block 43 passes through the stroke groove 14 for manual operation.

[0067] In this way, a person can operate the toggle block 43 to synchronously drive the buckle strip 42 to move within the range of the stroke groove 14, so that the buckle strip 42 can be moved away from the step 22 of the lifting platform 2 to release the lifting platform 2, realizing the unlocking operation of the lifting platform 2.

[0068] In an embodiment of the present application, as Figure 9 shown, the toggle block 43 is centrally arranged on the buckle strip 42. There is one second elastic member 41. One end of the second elastic member 41 is fixed inside the housing 1, and the other end of the second elastic member 41 is connected to the middle of the buckle strip 42. The buckle strip 42 is pushed towards the lifting platform 2 by the acting force of the second elastic member 41, so that the buckle strip 42 can be smoothly buckled with the step 22 on the outer periphery of the lifting platform 2.

[0069] In another embodiment of the present application, as Figure 7 and Figure 10 shown, the toggle block 43 is arranged in the middle of the buckle strip 42. The key lock 4 includes a pair of second elastic members 41. One ends of the pair of second elastic members 41 are respectively arranged close to both ends of the buckle strip 42. The other ends of the pair of second elastic members 41 extend parallel in the same direction and are fixed inside the housing 1.

[0070] Preferably, the pair of second elastic members 41 can adopt springs with the same length and uniform elastic force, which is beneficial to improving the synchronism.

[0071] In this embodiment, as Figure 10 shown, the buckle strip 42 has two connecting lugs 421 that match the number of the second elastic members 41. The two connecting lugs 421 are respectively arranged close to both ends of the buckle strip 42. In this way, one ends of the pair of second elastic members 41 are respectively connected to both sides of the toggle block 43 on the buckle strip 42, and the two second elastic members 41 can synchronously and smoothly drive the buckle strip 42 to push towards the lifting platform 2, so that the buckle strip 42 is flatly buckled on the step 22.

[0072] Due to the adoption of a pair of second elastic members 41 that move synchronously, the pushing force on the buckle strip 42 can be increased, ensuring that the buckle strip 42 can be buckled in place with the step 22, thereby improving the locking effect of the key lock 4. In addition, the pair of second elastic members 41 move synchronously with the buckle strip 42, which can also improve the feel of a person operating the key lock 4 and improve the use experience.

[0073] Making further improvements to the structure of the key lock 4. In an embodiment of the present application, please refer to Figure 8 and Figure 11, the button lock 4 further includes a support plate 44 disposed between the buckle strip 42 and the dial block 43. The plate surface of the support plate 44 is in flat contact with the inner top wall of the housing 1 to support the dial block 43 to protrude from the travel groove 14.

[0074] Wherein, the area of the plate surface of the support plate 44 is larger than the area of the travel groove 14 on the housing 1. So that on the plate surface of the support plate 44, the plate surface outside the vertical projection range of the notch of the travel groove 14 onto the support plate 44 can be in flat contact with the inner top wall of the housing 1.

[0075] Thus, the support plate 44 is used to support the dial block 43. Under the support of the support plate 44 and the inner top wall of the housing 1, the dial block 43 can protrude from the opening 11 of the housing 1 when a person applies force, facilitating the operation by hand. Without the support of the support plate 44, when a person operates the dial block 43, the dial block 43 will synchronously drive the buckle strip 42 to flip towards the inside of the housing 1, causing the dial block 43 to penetrate deeper into the housing 1, making it impossible for a person's finger to operate the unlocking, affecting the use experience. The support plate 44 is provided on the button lock 4 of the present application. Under the support of the support plate 44, the dial block 43 can be kept protruding from the travel groove 14 under the operation of a person's hand, effectively improving the operation stability of the button lock 4.

[0076] In practical applications, the jack group 21 provided on the lifting platform 2 has directional requirements, which are easily overlooked during the production process of the mobile socket, resulting in inaccurate installation direction of the lifting platform 2 and the need for reinstallation or repair, affecting production efficiency.

[0077] Therefore, for the installation and positioning structure of the lifting platform 2, in an embodiment of the present application, please refer to Figure 11 and Figure 12 , positioning notches 23 are provided on the steps 22 on at least one side of the lifting platform 2, and convex edges 441 capable of extending into the positioning notches 23 are provided at at least one end of the support plate 44. The convex edges 441 are in position cooperation with the positioning notches 23 on the lifting platform 2.

[0078] Thus, the positioning notches 23 on the lifting platform 2 and the convex edges 441 on the support plate 44 are engaged and matched to enable the lifting platform 2 to be installed on the housing 1 in a directional manner, thereby playing a role in preventing misinstallation of the lifting platform 2.

[0079] In this embodiment, as Figure 11 shown, the support plate 44 is provided on the buckle strip 42. A convex edge 441 is provided on the side of the support plate 44 close to the lifting platform 2, and the convex edge 441 protrudes from the buckle strip 42. Please combine Figure 3 , Figure 11 and Figure 12As shown, during the production process, the key lock 4 can be first installed inside the housing 1, and then the lifting platform 2 can be inserted into the housing 1 through the opening 11 on the housing 1. Due to the action of the second elastic member 41, the key lock 4 remains extended within the range of the opening 11, so that the convex edge 441 on the supporting plate 44 extends into the range of the opening 11. Therefore, only the side of the lifting platform 2 with the positioning notch 23 can be engaged and fitted with the convex edge 441, so that the lifting platform 2 can pass smoothly when inserted into the housing 1 through the opening 11; otherwise, the step 22 on the outer periphery of the lifting platform 2 will be blocked by the convex edge 441 of the supporting plate 44, making it impossible for the lifting platform 2 to be installed smoothly. In this way, an anti-misassembly effect is achieved.

[0080] Regarding the specific structure and installation structure of the first elastic member 3, it includes but is not limited to the following forms:

[0081] In an embodiment of the present application, please refer to Figure 7 and Figure 13 , the first elastic member 3 is preferably a spring 3a, and a fixing seat 24 with a shape matching the end of the spring 3a is provided on the inner wall of the lifting platform 2. One end of the first elastic member 3 is fixed to the inner wall of the housing 1, and the other end of the first elastic member 3 is fixed to the fixing seat 24. The lifting platform 2 is pushed up by the acting force of the first elastic member 3, or the first elastic member 3 is contracted by manually pressing the lifting platform 2 to reset the lifting platform 2.

[0082] In this embodiment, as Figure 13 shown, the end of the spring 3a is a circular spring wire; as Figure 7 shown, the fixing seat 24 is a circular base, so that the end of the spring 3a can be smoothly fixed on the fixing seat 24. Correspondingly, the circular fixing seat 24 can also be preferably provided on the inner bottom wall of the housing 1 to adapt to the end shape of the other end of the spring 3a, and the fixing effect of the other end of the spring 3a is also achieved.

[0083] In other embodiments, multiple springs 3a can also be arranged between the inner wall of the lifting platform 2 and the inner bottom wall of the housing 1 and are evenly distributed, and these springs 3a are respectively arranged in avoidance with the jack group 21 on the lifting platform 2. On the one hand, it is beneficial to improve the pushing force on the lifting platform 2, so that the lifting platform 2 can rise in place, and further ensure that the depth of each jack meets the insertion requirements of the pins of the electrical plug. On the other hand, it is beneficial to improve the smoothness of pushing the lifting platform 2 to rise, so that the lifting platform 2 can rise smoothly and avoid situations such as tilting and instability.

[0084] In another embodiment of the present application, please refer to Figure 9 and Figure 14, the first elastic member 3 is preferably a folding elastic piece 3b, and a fixing seat 24 matching the shape of the end of the first elastic member 3 is provided on the inner wall of the lifting table 2. One end of the first elastic member 3 is fixed to the inner wall of the housing 1, and the other end of the first elastic member 3 is fixed to the fixing seat 24.

[0085] In this embodiment, as Figure 9 shown, both ends of the folding elastic piece 3b are rectangular connecting pieces; as Figure 14 shown, the fixing seat 24 is a rectangular base adapted to the shape of the connecting piece, so that the end of the folding elastic piece 3b can be smoothly fixed on the fixing seat 24. Since the shapes of both ends of the folding elastic piece 3b are the same, a rectangular fixing seat 24 can also be provided on the inner bottom wall of the housing 1 to adapt to the shape of the end of the other end of the folding elastic piece 3b, and the fixing effect on the other end of the folding elastic piece 3b can also be achieved.

[0086] In this way, by using the elastic force of the folding elastic piece 3b, the technical effect of pushing the lifting table 2 to rise or being pushed back by hand is also achieved.

[0087] Regarding the setting manner of the first elastic member 3 on the housing 1, in the embodiment of the present application, please refer to Figure 3 and Figure 13 , the first elastic member 3 is disposed on the inner bottom wall of the housing 1 and is preferably located on the central axis of the housing 1. Please refer to Figure 7 and Figure 14 , the fixing seat 24 is disposed at the central part of the lifting table 2, and the jack group 21 on the lifting table 2 is arranged to avoid the fixing seat 24.

[0088] In this way, the first elastic member 3 is centered on the housing 1 and is also connected to the central part of the lifting table 2, which is beneficial to improving the smoothness of the first elastic member 3 pushing the lifting table 2 to rise, and also improving the stability of the operation of manually pressing the lifting table 2 to reset.

[0089] Regarding the expansion structure of the mobile socket of the present application, in an embodiment of the present application, the mobile socket of the present application can be integrated with the structure of a docking station. As Figure 2 shown, a part of the mobile socket is the power connection part of the above structure, which can allow the electrical plug of an external device to be inserted for power output. Another part of the mobile socket is the docking station structure. This part is provided with a plurality of expansion interfaces 15 on the housing 1. These expansion interfaces 15 are different types of data ports, and the types of these data ports can include but are not limited to TYPE-C, USB, HDMI, etc., so as to adapt to different terminals for data connection. Each expansion interface 15 can include one or more, and can be specifically set according to the available space on the mobile socket, and no specific limitation is made here.

[0090] Since the mobile socket can serve as a power supply connection terminal, each of the expansion interfaces 15 can also be used as a wired power supply interface. For example: the USB interface can be connected to a device to be charged, such as a smart phone or a tablet computer, or any device that can be charged through a data cable, to achieve a wired charging connection.

[0091] In another embodiment of the present application (not shown in the figure), the mobile socket of the present application can also integrate the function of a wireless charger. That is, a part of the mobile socket is the power connection part of the above structure, which can allow the electrical plug of an external device to be inserted for power output. Another part of the mobile socket is a wireless charging platform, and a wireless charging module is provided inside the housing 1. A smart terminal with wireless charging function, such as a smart phone, can be directly placed on this wireless charging platform to achieve wireless charging.

[0092] It can be seen that the mobile socket of the present application is small and thin in its own volume, convenient for storage and carrying out, and also integrated with other expansion function modules, suitable for use in composite application scenarios, further improving the overall performance of the mobile socket.

[0093] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
