Description

Technical Field

[0001] This invention relates to the field of mobile electronic device accessories, and more particularly to a handheld stand for electronic devices and an electronic device housing. Background Technology

[0002] Modern electronic products are becoming increasingly larger and heavier, making them difficult for ordinary consumers to operate with one hand. Existing solutions focus on how to make phones stand upright on a table, with few relatively effective and comfortable products to help consumers hold heavy, large electronic devices such as mobile phones.

[0003] US Patent Publication No. US11149902B2 discloses a grip and stand accessory for a mobile electronic device. Referring to paragraphs

[0008] -

[0021] of the specification, it includes: “The expandable accessory includes a base, a membrane, and a button coupled to the membrane opposite the base. The membrane includes multiple linear wall segments. The membrane is movable between a retracted position and an expanded position, and when the membrane is in the expanded position, the multiple linear wall segments are arranged in a common conical plane…”.

[0004] The above technical solution provides a handheld bracket for electronic devices. After fixing it to the main body or shell of a mobile phone or other mobile electronic device, multiple linear wall segments are unfolded to form a cone, allowing the user to hold the phone. The fingers are in a clamping motion on the back of the phone, which facilitates the gripping of the phone or other mobile electronic devices. It also enables the linear wall segments to be folded to shrink the diaphragm.

[0005] The aforementioned prior art has the following shortcomings: 1. Many linear wall sections are made of plastic, which is prone to aging over time. Repeated folding and stretching can cause fatigue damage to the film and wall sections, making them prone to failure.

[0006] 2. When consumers unfold and fold the device, the multiple linear walls create a pause effect, resulting in an unsmooth user experience.

[0007] 3. Each unfolding and folding of a linear wall generates noise. Summary of the Invention

[0008] The purpose of this invention is to provide a handheld stand for electronic devices to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a handheld support for an electronic device, comprising: Base: A housing used to fix or secure electronic devices to or to electronic devices; Telescopic spring: One end is fixed to the base, used to provide telescopic capability and support rod when the fingers are under pressure, providing two states for the handheld bracket: extended or retracted. Limiting cap: Fixed to the other end of the telescopic spring, serving as the end point of the telescopic spring's unfolding; Limiting component: Connected at both ends to the base and the limiting cover, used to limit the maximum extension length of the telescopic spring.

[0010] With the above solution, the telescopic spring can extend and retract more times than the wall segment in the existing technology, so its service life is longer. The spring can unfold and fold without stopping, making it smoother to use and eliminating the noise from multiple folds, thus providing greater comfort.

[0011] Furthermore, the shape of the telescopic spring is such that at least one part is conical, and the conical part of the telescopic spring has a small loop at one end and a large loop at the other end, spiraling upwards from the small loop to the large loop.

[0012] With the above solution, the small circle in the cone shape is easy for fingers to grip, and the cone-shaped telescopic spring can achieve full extension and contraction. Since a spring with the same thickness at the top and bottom will have its initial length when fully compressed and cannot fully retract, the cone shape can achieve full compression.

[0013] Furthermore, the diameters at both ends of the telescopic spring are larger than the diameter in the middle, forming a gripping portion in the middle that facilitates finger gripping.

[0014] Furthermore, the limiting component is a limiting rope with its two ends fixed to the limiting cover and the base, respectively.

[0015] Furthermore, the base has a first fixing hole for the limiting rope to pass through, and a first fixing ball is fixed to one end of the limiting rope that passes through the first fixing hole.

[0016] Furthermore, the base and the limiting cover are detachably and fixedly connected.

[0017] Furthermore, a first magnet is provided on the base, and a second magnet is provided on the limiting cover, for a detachable and fixed connection between the base and the limiting cover.

[0018] Furthermore, a snap-fit ​​post extends vertically from the center of the limiting cover, and a snap-fit ​​ring extends outward from the end of the snap-fit ​​post. The base has a snap-fit ​​hole for the snap-fit ​​ring to snap into. The snap-fit ​​ring and the snap-fit ​​hole are engaged to make the base and the limiting cover detachably and fixedly connected.

[0019] Furthermore, the base and the limiting cover are engaged, and an unlocking component is provided for unlocking and separating the base and the limiting cover. The unlocking component can be unlocked by pressing or rotating.

[0020] Furthermore, the base is provided with an annular embedding groove, the limiting cover is provided with a spring groove, and the two ends of the telescopic spring are respectively embedded in the spring groove and the embedding groove, and the telescopic spring is bonded to the embedding groove and / or the spring groove.

[0021] Furthermore, the base is provided with a snap-fit ​​component and / or an interceptor component, the snap-fit ​​component being used to fix the end point of the telescopic spring, and the interceptor component being used to fix the bottom edge of the telescopic spring.

[0022] Furthermore, it has two states: a contracted state and an extended state. In the contracted state, the spring is fully compressed, while in the extended state, the spring is in its natural state.

[0023] Furthermore, the side of the base away from the limiting cover is provided with double-sided adhesive tape or a magnet for fixing to electronic devices or their protective cases.

[0024] Furthermore, in the extended state of the handheld bracket, the telescopic spring is in a natural state, and the limiting rope is either straight but not under force or loose and not under force.

[0025] Furthermore, when the handheld bracket is extended, the telescopic spring is in a compressed state, and the limiting rope is subjected to the tension brought by the telescopic spring.

[0026] Furthermore, the base is provided with a locking space for engaging one side of the limiting cover. The locking space is used to engage one side of the limiting cover with the base, forming an unfolded usage state.

[0027] Furthermore, the limiting component includes a limiting film fixed at both ends to the limiting cover and the base respectively, and the limiting film is attached to the outside of the telescopic spring.

[0028] Another technical solution provided in this application is: an electronic device housing, characterized in that an electronic device handheld bracket is provided on the back of the electronic device housing, the electronic device handheld bracket comprising: Base: Attached to or part of the casing of an electronic device; Telescopic spring: One end is fixed to the base, used to provide telescopic capability and support rod when the fingers are under pressure, providing two states for the handheld bracket: extended or retracted. Limiting cap: Fixed to the other end of the telescopic spring, serving as the end point of the telescopic spring's unfolding; Limiting component: Connected at both ends to the base and the limiting cover, used to limit the maximum extension length of the telescopic spring.

[0029] Furthermore, the electronic device housing has a receiving groove for the electronic device handheld bracket to be inserted into when it is in the retracted state. When the handheld bracket is retracted, the handheld bracket is fully or partially inserted into the receiving groove.

[0030] In summary, the present invention has the following advantages compared with the prior art: 1. The elastic fatigue resistance of the telescopic spring is significantly increased compared to the wall segment folding in the background technology, thus improving its service life; 2. The limiting component restricts the maximum extension distance of the telescopic spring, solving the technical problem of unstable extension length that may be caused by the selection of spring. The UHMWPE high tensile strength and high wear resistance rope used in the limiting component can withstand a tensile force of more than 10 kg, which can support the auxiliary handheld use of tablet computers. In contrast, the product structure of the wall section is fragile and not suitable for the auxiliary handheld use of larger electronic devices. 3. This technology solves the problem of multiple pauses during use at the folded parts of multiple linear wall sections in the existing technology, resulting in smoother operation; 4. The rapid expansion and contraction of the spring eliminates the noise caused by multiple pauses; 5. The spring can open at multiple angles relative to the wall section, allowing the user's fingers to bend and move freely. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example 1: A handheld stand for an electronic device. The electronic device can be a mobile phone 1, a power bank, a tablet computer, a game controller, a remote control for a drone, etc. In this example, a mobile phone 1 is selected as the electronic device. (Refer to...) Figure 1 , Figure 2 The device includes a disc-shaped base 1 and a disc-shaped limiting cover 2. A telescopic spring 3 is provided between the base 1 and the limiting cover 2. The two ends of the telescopic spring 3 are fixed to the base 1 and the limiting cover 2 respectively, fixing the base 1 to the back of the phone 1. When using the phone 1, the middle and index fingers can hold the telescopic spring 3, making it easy to grip the phone 1. The phone 1 is not easy to fall when in use.

[0035] A limiting member 4 is also provided between the base 1 and the limiting cover 2 to limit the maximum stretching distance of the telescopic spring 3. In this embodiment, the limiting member 4 is a UHMWPE high tensile strength and high wear resistance rope, called the limiting rope 40. In other embodiments, it can be other types of limiting rope 40. The two ends of the limiting rope 40 are fixed at the center of the base 1 and the limiting cover 2 respectively.

[0036] Reference Figure 3 The base 1 has two sides, a front and a back. The back side is provided with double-sided adhesive tape 5 for fixing to the mobile phone 1. In other embodiments, the base 1 is fixed to the mobile phone 1 by integrally connecting the base 1 to the phone case, or by adhesive bonding. The front side is used to fix the telescopic spring 3. The front side of the base 1 has an annular outer ridge 13 protruding upwards. A bottom fixing member 130 for fixing the telescopic spring 3 is provided inside the outer ridge 13. In this embodiment, the bottom fixing member 130 includes an inner ridge 10 concentric with the outer ridge 13. The outer ridge 13 and the inner ridge 10 form an embedding groove 14. One end of the telescopic spring 3 is fixed in the embedding groove 14. In this embodiment, the fixing method is to glue the telescopic spring and the base 1 together in the embedding groove 14. The limiting cover 2 has a spring groove 22 on the side facing the base 1 to accommodate the other end of the telescopic spring 3 and is fixed with glue, forming a top fixing member 131.

[0037] The diameters at both ends of the telescopic spring 3 are larger than the diameter at the middle, forming a clamping portion 30 in the middle for easy gripping. In another embodiment, the base 1 has a tapered shape with one end narrower than the limiting cover 2, and the narrow end is the clamping portion 30. In use, the clamping portion 30 is used for gripping the fingers when holding the mobile phone 1.

[0038] A first magnet 70 in the shape of a ring is fixedly installed at the center of the base 1. In this embodiment, it is fixed by adhesive bonding. A second magnet 71 is installed on the limiting cover 2. The first magnet 70 and the second magnet 71 attract each other. The periphery of the first magnet 70 protrudes upward with a limiting ridge 11. The first magnet 70 is embedded in the circular space 12 enclosed by the limiting ridge 11. The second magnet 71 is located on the side of the limiting cover 2 away from the base 1. When the side of the limiting cover 2 away from the base 1 is the observation reference plane, the limiting cover 2 has a recessed annular receiving space 20 for accommodating the second magnet 71. The second magnet 71 is fixed in the receiving space 20.

[0039] The magnetic adsorption method makes opening and closing more convenient. Furthermore, since the magnetic method can be opened not only by vertical separation but also by horizontal misalignment, combined with the flexibility of the spring and the limiting rope 40 and the spring force, the bracket can be opened more conveniently. Simply push the limiting cover 2 to the side to open the bracket.

[0040] A fixing hole is provided at the center of the base 1. The limiting rope 40 passes through the fixing hole and is knotted for fixation. The center of the base 1 bulges towards the limiting cover 2, forming a fixing space 26 on the back of the base 1 to accommodate the first fixing ball 41 formed by the knotted limiting rope 40. In other embodiments, the first fixing ball 41 can be a solid plastic ball, metal ball, or other spherical object that can prevent the limiting rope 40 from detaching from the fixing hole, or a non-spherical object, all of which can serve as the first fixing ball 41.

[0041] A second fixing hole 23 is opened in the center of the limiting cover 2 so that the other end of the limiting rope 40 can be passed through and knotted to form a second fixing ball 42. The limiting cover 2 is provided with a fixing space 26 to accommodate the second fixing ball 42. The fixing space 26 is located in the center of the accommodating space 20 and is provided with a partition ring 21 for isolation.

[0042] A magnetic shielding sheet 8 is fixed to the side of the second magnet 71 facing away from the base 1. The magnetic shielding sheet 8 is made of metal; in this embodiment, it is an iron sheet. This reduces the risk of demagnetizing magnetic cards such as credit cards and bank cards that may be placed with electronic products like mobile phones 1 by passing through the top cover 27. The limiting cover 2 is fastened to the side of the limiting cover 2 facing away from the base 1 by the top cover 27, which is used to cover the limiting cover 2. The magnetic shielding sheet 8 is attached to the top cover 27, allowing the top cover 27 to directly attract the second magnet 71 using the magnetism of the iron sheet, thus making the top cover 27 replaceable.

[0043] Reference Figure 4 , Figure 5 The base 1 has a first through hole 16 for the first fixed ball 41 to pass through. The side wall of the first through hole 16 has a first through groove 17 that connects to the first fixed hole 15. After the first fixed ball 41 passes through the through hole, it slides from the through groove to the fixed hole and is embedded in the fixed space 26.

[0044] The second fixed ball 42 is connected to the limiting cover 2 in the same way. The limiting cover 2 is provided with a second through hole 24. The side wall of the second through hole 24 is provided with a second through groove 25. The second through groove 25 is connected to the second fixed hole 23. The diameter of the fixed hole and the through groove is smaller than the diameter of the fixed ball.

[0045] Reference Figure 6 , Figure 7 When the base 1 and the limiting cover 2 are retracted, the telescopic spring 3 is compressed. Since the telescopic spring 3 is thin in the middle and thick at both ends, it can be fully retracted.

[0046] Both the base 1 and the limiting cover 2 have fastening parts 6 extending in opposite directions, and the two fastening parts 6 enclose the retracted telescopic spring 3.

[0047] In this embodiment, the telescopic spring 3 is a piano steel spring, and the limiting cover 2 and the base 1 are made of zinc alloy.

[0048] Reference Figure 8 , Figure 9 When holding an electronic device using a handheld bracket, the limiting cover 2 can be erected and one side of the limiting cover 2 can be embedded into the base 1. The outer protruding rib 13 of the base 1 and the fastening part 6 form a ring-shaped locking space 60. When the limiting cover 2 is erected and one side of the limiting cover 2 is embedded into the locking space 60, the limiting cover 2 and the base 1 are locked together to achieve temporary positioning. When holding the electronic device, four fingers can be used to hold the bottom surface of the limiting cover 2, which can provide another comfortable way of holding it. At this time, the state of the telescopic spring 3 is one side compressed and one side stretched.

[0049] Combination Figure 9 In this usage state, when holding the electronic device, a stable triangular support structure is formed between the palm and the handheld bracket, and the handheld bracket itself also forms a triangular structure, making it more stable.

[0050] In the specific implementation process, the consumer, i.e., the user, uses double-sided adhesive tape 5 to attach the base 1, along with the product of this embodiment, to the device that needs assistance. In this embodiment, a mobile phone 1 is selected. If the product is in a roughly extended state, it can be used directly. If the product is in a closed state, the limiting cover 2 needs to be moved with a finger to overcome the attraction of the first magnet 70 and the second magnet 71, so that the limiting cover 2 is separated from the base 1. After the telescopic spring 3 is extended, the tension of the limiting rope 40 prevents the telescopic spring 3 from extending further. At this time, the distance between the limiting cover 2 and the base 1 is the design height during production. The top cover 27 is the surface for external display and is attracted to the limiting cover 2 by the second magnet 71. Different styles can be customized for replacement. If the consumer wants to change the appearance style due to their preferences, it is not necessary to buy the whole set of products. Only the top cover 27 needs to be purchased for replacement, which is more adaptable. At the same time, the setting of the magnetic shielding sheet 8 can reduce the magnetic field emitted by the magnet, reducing the risk of demagnetizing credit cards and other cards.

[0051] When the consumer is not using this product, simply press the top cover 27 to overcome the elasticity of the telescopic spring 3, allowing the two magnets to approach each other and enter the magnetic force range. In this embodiment, the product will be in a folded state for easy carrying.

[0052] In another usage scenario, when the finger is moved to one side of the limiting cover 2, the limiting cover 2 stands up, causing one side of the telescopic spring 3 to compress and the other side to stretch, forming... Figure 9 In this state, one side of the limiting cover 2 is embedded in the locking space 60, and the finger is gripped on the other side of the limiting cover 2. At this time, the limiting rope 40 is straightened. This hand-holding method can be selected according to the user's habits.

[0053] Example 2, refer to Figure 10 , 11 The difference between this embodiment and Embodiment 1 is that the bottom fixing member 130 includes a snap-fit ​​member 18 disposed inside the outer protruding ridge 13. The snap-fit ​​member 18 includes a first strip-shaped hole 181 formed on the base 1, a fixing plate 180, and a plug plate 182. The first strip-shaped hole 181 is arc-shaped along the inner wall of the outer protruding ridge 13. The fixing plate 180 has an L-shaped cross-section. One end of the fixing plate 180 is vertically fixed to the top edge of the outer protruding ridge 13, and the other end is vertically fixed to the base 1. The plug plate 182 is fixed perpendicular to the base 1 at one end of the first strip-shaped hole 181. The plug plate 182 is integrally connected to the fixing plate 180. The length of the fixing plate 180 is less than the length of the first strip-shaped hole 181 so that the end of the first strip-shaped hole 181 away from the plug plate 182 protrudes from the top surface of the base 1. The end of the telescopic spring 3 passes through the first strip-shaped hole 181 and abuts against the plug plate 182, thus fixing the telescopic spring 3.

[0054] The bottom fixing member 130 also includes an interceptor 19 located on the outer protrusion 13 and opposite to the snap-fit ​​member 18. The interceptor 19 includes an interceptor plate 190 that is vertically fixed on the side of the outer protrusion 13 near the center of the base 1. The interceptor plate 190 is L-shaped, with one end fixed to the inner side of the outer protrusion 13 and the other end vertically fixed to the base 1. In other embodiments, the interceptor plate 190 can be replaced with an interceptor rod.

[0055] The end of the telescopic spring 3 that is fixed to the base 1 extends into the space enclosed by the interceptor plate 190 and the outer protrusion 13. After rotation, the edge of the telescopic spring 3 moves along the inner wall of the outer protrusion 13 toward the fixing plate 180 until the end of the telescopic spring 3 enters the fixing plate 180 and contacts the end plate 182, thus completing the fixing of the end plate 182.

[0056] To facilitate the installation of the telescopic spring 3, a second strip-shaped hole 191 is provided on the base 1 at the position corresponding to the interceptor plate 190. The design of the second strip-shaped hole 191 and the first strip-shaped hole 181 makes the installation process of the telescopic spring 3 more convenient and avoids the installation difficulties caused by the narrow space between the interceptor plate 190 and the base 1.

[0057] The inner side of the interceptor plate 191 is glued to the edge of the telescopic spring 3, and the inner side of the fixing plate 181 is glued to the end point of the telescopic spring 3.

[0058] The limiting cover 2 is provided with a top fixing member 131 that is the same in shape, size and function as the bottom fixing member 130 on the base 1, and is located inside the fastening part 6.

[0059] In another embodiment, there is no first strip hole 181 and second strip hole 191. The interceptor plate 190 is fixed on the base 1 and a space is reserved between the interceptor plate 190 and the base 1 for the edge of the telescopic spring 3 to be embedded. The fixed plate 180 and the base 1 form a space for the end of the telescopic spring 3 to be embedded.

[0060] The snap-fit ​​component 18 may not include the end plate 182. The fixing plate 180 can be used independently as the snap-fit ​​component 18. In other embodiments, the snap-fit ​​component 18 can be other shapes, such as a semi-ring shape with both ends fixed to the base 1, or an arc shape with one end fixed to the base 1 and the other end fixed to the outer protrusion 13. The cross-section can be plate-shaped or rod-shaped.

[0061] In other embodiments, the interceptor 19 can be of other shapes, such as a semi-ring shape with both ends fixed to the base 1, or an arc-shaped stool with one end fixed to the base 1 and the other end fixed to the outer protruding rib 13. The cross-section can be plate-shaped, rod-shaped, or hollow tube-shaped.

[0062] Example 3, combined with Figure 12 , 13 In this embodiment, the limiting member 4 is a limiting film 43 with its two ends fixed to the limiting cover 2 and the base 1 respectively. The limiting film 43 is made of non-woven fabric, polyester fiber, cotton cloth or high tear-resistant silicone rubber material.

[0063] In this embodiment, the limiting film 43 is attached to the outer edge of the telescopic spring 3; in other embodiments, there is a gap between the telescopic spring 3 and the limiting film 43.

[0064] In another embodiment, the two ends of the limiting membrane 43 are fixed to the outer edge of the limiting cover 2 and the outer edge of the base 1, respectively. The limiting membrane 43 is cylindrical and the entire limiting membrane 43 serves as a clamping part for finger clamping during handholding.

[0065] In this embodiment, the locking mechanism between the limiting cover 2 and the base 1 is used to fix the limiting cover 2 in the closed state and facilitate its unfolding in the extended state.

[0066] The snap-fit ​​structure between the limiting cover 2 and the base 1 includes a snap-fit ​​post 90 vertically fixed at the center of the limiting cover 2, a snap-fit ​​ring 91 extending outward from the end of the snap-fit ​​post 90, and a snap-fit ​​hole 92 for the snap-fit ​​ring 91 to be inserted at the center of the base 1. The snap-fit ​​ring 91 is made of flexible material, and the diameter of the snap-fit ​​hole 92 is smaller than the diameter of the snap-fit ​​ring 91.

[0067] In the closed state, the snap ring 91 is embedded in the snap hole 92 to restrict the two from unfolding. When it is necessary to unfold, an external force is applied to push the limiting cover 2 outward, thereby deforming the snap ring 91, thereby disengaging the snap ring 91 from the snap hole 92, and thus allowing the limiting cover 2 and the base 1 to unfold.

[0068] In other embodiments, the limiting rope 40 and the limiting membrane 43 may both exist, or one of the limiting rope 40 and the limiting membrane 43 may be retained. In another embodiment, the snap ring 91, the snap post 90, the snap hole 92 and the magnet may coexist or one of them may be retained as a snap structure to realize the detachable connection between the limiting cover 2 and the base 1.

[0069] In other embodiments, the snap-fit ​​structure can be a detachable connection structure such as a buckle or a magnet located at the edge of the limiting cover 2 and the base 1.

[0070] In this embodiment, as such Figure 9 The method of using the magnetic shielding sheet still applies. At this time, the limiting membrane is in a relaxed state on the side compressed by the telescopic spring, and in a taut state on the other side.

[0071] In one embodiment, the base 11 is fixed to the phone case 100 for use. In another embodiment, the phone case 100 is used as the base 1, and the structure on the base 1 is directly set on the back of the phone case 100. The phone case is equipped with a through hole for the handheld structure to pass through.

[0072] Example 4, refer to Figure 14 The difference between this embodiment and embodiment 3 is that the locking and unlocking method of the locking structure 9 is push-to-unlock, specifically: Four elastic pieces 93 are fixed vertically downward on the limiting cover 2. In other embodiments, there may be two or three elastic pieces 93. The outer surface of the elastic piece 93 extends outward with a snap-fit ​​edge 94. A snap-fit ​​hole 92 is opened at the center of the bottom shell. After the elastic piece 93 is pressed inward, the snap-fit ​​edge 94 enters the snap-fit ​​hole 92. Due to the elastic force of the elastic piece 93, the snap-fit ​​edge 94 rebounds and snaps into the snap-fit ​​hole 92.

[0073] The outer ring of the ring formed by multiple elastic pieces 93 is the same size as the inner ring of the snap-fit ​​hole 92 and is arranged concentrically. When the snap-fit ​​edge 94 springs back and snaps into the snap-fit ​​hole 92, the elastic piece 93 contacts the snap-fit ​​ring 91 and is not subjected to force.

[0074] When the limiting cover 2 and the base 1 are closed by the snap-fit ​​structure 9, it is no longer possible to unlock by pressing the elastic piece 93 towards the center. Therefore, in this embodiment, the snap-fit ​​structure 9 also includes an unlocking component 95. The unlocking component 95 includes an unlocking button 950, which is located on the side of the limiting cover 2 away from the base 1. An unlocking plate 952 is vertically fixed to the bottom surface of the unlocking button 950. The unlocking plate 952 passes through the limiting cover 2 and is vertically slidably connected to the limiting cover 2. The number of unlocking plates 952 corresponds one-to-one with the number of elastic pieces 93. The ring formed by the unlocking plate 952 is concentric with the ring formed by the elastic sheet 93. The inner circle of the ring formed by the unlocking plate 952 is equal to the outer circle of the ring formed by the elastic sheet 93. An unlocking spring 951 is sleeved on the outside of the unlocking plate 952. The two ends of the unlocking spring 951 abut against the unlocking button 950 and the limiting cover 2, respectively. The unlocking spring 951 is located between the unlocking button 950 and the limiting cover 2. A retaining edge 953 is provided between the unlocking plate 952 and the limiting cover 2 to prevent the unlocking plate 952 from passing through the top of the limiting cover 2.

[0075] The unlocking button protrudes outward from the middle of the elastic sheet 93. The relative positions of the unlocking twist 930 and the unlocking plate 952 are as follows: when the locking edge 953 touches the limiting cover 2, the end of the unlocking plate 952 away from the unlocking button 950 contacts the unlocking twist 930. Both the ends of the unlocking twist 930 and the unlocking plate 952 are provided with bevels, which are used to make the unlocking twist 930 and the unlocking plate 952 cooperate so that the unlocking plate 952 presses the unlocking twist 930 toward the center. When the unlocking twist 930 is pressed by the unlocking plate 952, the locking edge 953 disengages from the locking hole 92, and the elastic force of the telescopic spring 3 causes the limiting cover 2 to separate from the base 1, and the handheld bracket is deformed into an unfolded state.

[0076] In another embodiment, any form of the snap-fit ​​structure 9 can coexist with the limiting rope 40, or coexist with both the limiting rope 40 and the limiting membrane 43.

[0077] In another embodiment, the back of the phone 100 case has a receiving groove for accommodating the handle bracket, which can be fully or partially inserted into the receiving groove when the handle bracket is retracted.

[0078] In another embodiment, the back of the mobile phone 100 body is connected as a base 1, and the structure on the base 1 is directly disposed on the back of the mobile phone 100 body. A through hole for a handle bracket is provided on the mobile phone 100 casing. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0079] In another embodiment, the latching structure 9 is opened by rotation, such as... Figure 13 The bottom end of the limiting post 90 extends to one side with a locking plate, which is unlocked by rotating the limiting cover 2. Due to the resilience of the telescopic spring 3, the rotation process only needs to overcome the spring force; or as... Figure 14 The card slot 92 is provided with a groove for the card edge 94 to pass through. By rotating the unlock button 950, the card edge 94 is allowed to pass through the groove. In this way, the elastic piece 93 may not be elastic.

[0080] In another embodiment, the limiting cover 2 and the base 1 are connected by an electromagnet. Specifically, the limiting cover 2 is equipped with an electromagnet and an electromagnetic switch. The electromagnetic switch can be remotely controlled by a mobile phone and / or controlled by NFC. The detachable connection between the limiting cover 2 and the base 1 is achieved by turning the electromagnet on and off.

[0081] It is worth noting that as long as the opening and closing mechanism between the limit cover 2 and the base 1 allows the consumer to open and close it as needed, it is considered a detachable connection.
