Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone accessories, in particular to a sealed and waterproof mobile phone shell. Background Art

[0002] When using a mobile phone, in order to effectively avoid damage caused by collision, falling or water ingress, a mobile phone protective case is usually placed on the outside of the mobile phone to protect the mobile phone.

[0003] In the related art, for example, Chinese patent CN117061654B discloses a self-test sealing device for a waterproof mobile phone protective case. Its working mechanism is as follows: when in use, first press the pressure plate to cause the soft-glue folding cavity to be retracted into the interior of the fixed frame, and then the buckle on the fixed frame and the first slot on the pressure frame are engaged and fixed to each other. During the folding and retraction process of the soft-glue folding cavity, the air inside it will be squeezed to the front transparent soft film inside the front mobile phone case, causing the front transparent soft film to bulge. If the bulging front transparent soft film can keep the air in the internal cavity from dissipating for a certain period of time, it means that the cavity is in a sealed state, which can be used to visually check the waterproof effectiveness of the mobile phone protective case.

[0004] However, the aforementioned self-test sealing device for waterproof mobile phone cases has many problems in actual application: First, when the front transparent soft film bulges, the user needs to press it down to operate the phone. However, due to the different hand feel of different users and the fixed bulge of the front transparent soft film, users with soft hands will find it more difficult to press, resulting in a poor user experience; users with hard hands may press too hard, which can easily damage the front transparent soft film. Second, in special environments, such as when using a phone underwater, the water pressure will cause the bulge of the front transparent soft film to decrease, which can easily cause screen jumping. However, if the front transparent soft film is set with a large initial bulge to cope with underwater scenarios, it will be very difficult for the user to press it when operating above water. At the same time, the front transparent soft film is prone to rupture due to excessive deformation, resulting in sealing failure. Summary of the Invention

[0005] Based on this, it is necessary to provide a sealed and waterproof mobile phone shell to address the problem of poor adaptability of current mobile phone protective shells during use.

[0006] The above purpose is achieved through the following technical solutions: A sealed and waterproof mobile phone housing, comprising: A front housing, wherein a front transparent soft film is provided on the front housing; A rear housing, on which a rear soft film is provided; the rear housing is sealed and clamped with the front housing when in use, and the rear housing, the rear soft film, the front housing, and the front transparent soft film together surround a cavity, and the cavity is configured to accommodate a mobile phone; A spring piece is located in the mold cavity and is provided on the rear housing; the spring piece protrudes rearward and forms a stopper with the rear soft film; A pressure rod is located outside the mold cavity, with a first end hinged to the front shell and a second end capable of being snapped onto the front shell and capable of forming a stop fit through the rear soft film and the raised portion of the elastic sheet; The adjustment mechanism is configured to be able to adjust the degree of protrusion of the protruding portion of the elastic sheet.

[0007] Furthermore, the adjustment mechanism includes a card hole and a slider, and a plurality of the card holes are provided on the spring sheet, and the plurality of the card holes are arranged at intervals along the extension direction of the spring sheet; the slider is provided on the rear shell, and is connected to the rear shell through an elastic member, and can form a card fit with the card hole. Under the action of the elastic member, the slider can slide along the extension direction of the spring sheet and has a tendency to compress the spring sheet.

[0008] Furthermore, the elastic member is a compression spring.

[0009] Furthermore, the compression spring is an S-shaped structure.

[0010] Furthermore, a first clamping slot is provided on the pressure rod; and a clamping portion is provided on the front shell, and the clamping portion can be clamped with the first clamping slot.

[0011] Furthermore, the clamping portion can rotate around its own axis and has corresponding locked and unlocked states before and after rotation. When in the locked state, the clamping portion and the first clamping slot are clamped, and when in the unlocked state, the clamping portion and the first clamping slot are disengaged.

[0012] Furthermore, a slot is provided on the rear shell, and the slot is close to the hinge point between the pressure rod and the front shell; the pressure rod is provided with a spring protrusion, and the spring protrusion can be inserted into the slot and can form a stop fit with the slot.

[0013] Furthermore, a charging port is provided at the bottom of the front shell, and a plug is provided to seal the charging port.

[0014] Furthermore, the plug is elastically hinged to the rear shell, and has a tendency to block the charging port under the action of elasticity.

[0015] Furthermore, the first end of the pressure rod and the front shell are frictionally hinged.

[0016] The beneficial effects of the present invention are: The present invention relates to a sealed and waterproof mobile phone shell. By providing a spring piece and a pressure rod and providing an adjustment mechanism cooperating therewith, the degree of convexity of the convex portion of the spring piece can be adjusted. After the pressure rod and the front shell form a snap fit, the air pressure inside the cavity is adjusted, and the bulging degree of the front transparent soft film is further adjusted. Therefore, the shell can be adapted to the hand feel of different users and various environments, thereby improving applicability.

[0017] Furthermore, by setting a slot and a spring protrusion, and utilizing the special spatial position of the slot close to the hinge point between the pressure rod and the front shell, when the cavity needs to be opened, the front shell and the rear shell can be automatically separated by rotating the pressure rod and pushing the slot through the spring protrusion, thereby improving the ease of operation.

[0023] Refer to the following Figures 1 to 10 The sealed and waterproof mobile phone housing provided by the embodiment of the present invention is described below. The sealed and waterproof mobile phone housing is particularly suitable for waterproofing mobile phones. Of course, the sealed and waterproof mobile phone housing is also suitable for waterproofing other electronic mobile devices such as tablets and tablet computers.

[0024] Specifically, a sealed and waterproof mobile phone housing is configured to include a front housing 1 and a rear housing 2. The front housing 1 is a box-like structure with an open rear sidewall. A first opening 103 is defined on the front sidewall of the front housing 1. A front transparent soft film 101 is fixedly sealed to the first opening 103. The first opening 103 at least covers the display area of ​​the mobile phone screen, allowing the front transparent soft film 101 to fully display the mobile phone screen without affecting normal use of the mobile phone. The rear housing 2 is also a box-like structure with an open front sidewall. A second latching groove 104 is defined on the outer peripheral wall of the front housing 1. An elastic latching protrusion 204 is provided on the inner peripheral wall of the rear housing 2. The elastic latching protrusion 204 can be engaged with the second latching groove 104, thereby achieving a sealed latching connection between the rear housing 2 and the front housing 1. Optionally, both the elastic latching protrusion 204 and the second latching groove 104 can be configured as an annular structure. The rear housing 2 , the front housing 1 and the front transparent soft film 101 together form a cavity 3 , and the cavity 3 is configured to accommodate a mobile phone.

[0025] Existing waterproof phone cases typically have a second opening 203 on the rear sidewall of the rear housing 2. A folded portion is fixedly positioned at the second opening 203. The folded portion has a cavity that communicates with the mold cavity 3. When a phone is placed in the mold cavity 3, the folded portion compresses, reducing the combined volume of the cavity and mold cavity 3 and increasing the pressure, causing the front transparent soft film 101 to bulge. This provides both waterproof protection and allows visual inspection of the phone case's waterproofing effectiveness. However, the fixed bulge degree of the front transparent soft film 101 cannot adapt to the operating feel of different users, resulting in polarized operating experience, which not only affects the convenience of use, but also increases the risk of component damage; at the same time, facing the pressure difference between different environments above water and underwater, the fixed bulge degree of the front transparent soft film 101 is difficult to take into account the usage requirements of both scenarios. The change in the bulge degree of the front transparent soft film 101 under the action of water pressure will cause functional failure, and forcibly increasing the initial bulge degree of the front transparent soft film 101 will bring new operational difficulties and hidden dangers of component damage, which seriously restricts the reliability and applicability of the waterproof mobile phone protective case in complex environments.

[0026] Based on this, in the sealed and waterproof mobile phone housing provided by the embodiment of the present invention, a rear soft film 201 is fixedly sealed at the second opening 203, and the cavity 3 is formed by the rear shell 2, the rear soft film 201, the front shell 1 and the front transparent soft film 101. A spring piece 4 is provided in the cavity 3, and the spring piece 4 extends in the vertical direction and corresponds to the second opening 203. The top end of the spring piece 4 is fixed on the rear inner wall of the rear shell 2 and is located above the second opening 203. The bottom end is suspended and is located below the second opening 203. The spring piece 4 protrudes backward, and the protruding part pushes on the rear wall. On the soft film 201, it forms a stop fit with the rear soft film 201; a pressure rod 5 is provided outside the cavity 3, the top end of the pressure rod 5 is hinged to the top of the front shell 1, and then the whole can be sleeved on the partial top of the front shell 1, the rear shell 2 and the bottom of the front shell 1; in order to achieve the card connection between the pressure rod 5 and the front shell 1, it can be provided to have a third card groove on the bottom front side wall of the front shell 1, and a card protrusion is provided on the rear side wall of the bottom end of the pressure rod 5, the card protrusion is made of elastic material, such as rubber, and can be carded in the third card groove, thereby enhancing the connection stability between the rear shell 2 and the front shell 1.

[0027] The sealed and waterproof mobile phone housing is further configured to include an adjustment mechanism 6, which is configured to adjust the degree of convexity of the raised portion of the spring clip 4. Thus, before placing the mobile phone into the cavity 3, the degree of convexity of the raised portion of the spring clip 4 can be pre-adjusted based on the user's hand feeling or the circumstances of use above or below water, thereby meeting different usage requirements and improving applicability. Specifically, when the user's hand feeling is light or the mobile phone is used above water, the adjustment mechanism 6 is used to adjust the convexity of the raised portion of the spring clip 4 to a smaller degree. At this time, the raised portion of the spring clip 4 less supports the rear soft film 201, and the volume of the cavity 3 is relatively small. The mobile phone is then placed into the cavity 3, and the pressure rod 5 is then driven to rotate toward the rear housing 2 until the locking protrusion engages with the third locking slot. During the rotation of the pressure rod 5, since the convex part of the spring sheet 4 is less convex, the pressure rod 5 will lag behind in passing through the rear soft film 201 and abutting against the convex part of the spring sheet 4; after the pressure rod 5 passes through the rear soft film 201 and abuts against the convex part of the spring sheet 4, as the pressure rod 5 continues to move, the pressure rod 5 drives the convex part of the spring sheet 4 to move backward through the rear soft film 201. Since the final rotation position of the pressure rod 5 remains unchanged, the volume of the cavity 3 will decrease but the decrease is small, and the pressure will increase accordingly but the increase is small, so that it can adapt to the user's lighter hand or the situation of using the mobile phone on water, and make the front transparent soft film 101 bulge, which can not only achieve waterproof protection, but also can visually check the waterproof effectiveness of the mobile phone protective case.

[0028] Similarly, when the user's hand feels heavier or the mobile phone is used underwater, the raised part of the adjusting spring 4 is more convex. At this time, the raised part of the spring 4 supports the rear soft film 201 to a greater extent, and the volume of the cavity 3 is relatively large. Then the mobile phone is placed in the cavity 3, and then the pressure rod 5 is driven to rotate in the direction close to the rear shell 2 until the convex part and the third slot are engaged. During the rotation of the pressure rod 5, due to the large outward convexity of the raised part of the spring sheet 4, the pressure rod 5 will pass through the rear soft film 201 and abut against the raised part of the spring sheet 4 in advance; when the pressure rod 5 passes through the rear soft film 201 and abuts against the raised part of the spring sheet 4, as the pressure rod 5 continues to move, the pressure rod 5 drives the raised part of the spring sheet 4 to move backward through the rear soft film 201. Since the final rotation position of the pressure rod 5 remains unchanged, the volume of the cavity 3 will decrease and the decrease will be large, and the pressure will increase accordingly and the increase will be large, so that it can adapt to the user's heavy hand feel or the use of the mobile phone underwater, and make the front transparent soft film 101 bulge, which can not only achieve waterproof protection, but also enable visual inspection of the waterproof effectiveness of the mobile phone protective case.

[0029] At the same time, after the pressure rod 5 contacts the raised portion of the spring clip 4 through the rear soft film 201, the spring clip 4 exerts a backward force on the pressure rod 5. Since the pressure rod 5 is hingedly connected to the front shell 1, the pressure rod 5 can transmit the force of the spring clip 4 to the front shell 1, causing it to have a tendency to move backward. The pressure rod 5 correspondingly exerts a forward force on the spring clip 4. Since the spring clip 4 is fixedly connected to the rear shell 2, the spring clip 4 can transmit the force of the pressure rod 5 to the rear shell 2, causing it to have a tendency to move forward, thereby making the front shell 1 and the rear shell 2 have a tendency to be connected more tightly, thereby helping to enhance the connection stability and sealing between the front shell 1 and the rear shell 2, and ensuring the waterproof effect. Moreover, when the raised portion of the spring clip 4 is more convex, after the pressure rod 5 contacts the raised portion of the spring clip 4 through the rear soft film 201, the interaction force between the spring clip 4 and the pressure rod 5 will be greater, thereby helping to further enhance the connection stability and sealing between the front shell 1 and the rear shell 2, and further ensuring the waterproof effect.

[0030] Furthermore, the adjustment mechanism 6 is configured to include a card hole 601 and a slider 602. A plurality of card holes 601 are provided on the front side wall of the bottom end of the spring piece 4. The plurality of card holes 601 are arranged at equal intervals along the extension direction of the spring piece 4. A slide rail 205 is fixedly provided on the rear inner side wall of the rear shell 2. The slide rail 205 is located below the second opening 203 and is a U-shaped structure with the opening facing upward. A slideway 2051 is formed between the slide rail 205 and the rear shell 2. The slider 602 is slidably inserted into the slideway 2051 during installation and can slide in the vertical direction. When the slider 602 slides upward, it can move with the rear shell 2 The shell 2 forms a stop fit to have an upper limit sliding position; an insertion protrusion 6021 is fixedly provided on the front side wall of the slider 602, and the insertion protrusion 6021 can be inserted into the card hole 601 and can form a snap fit with the card hole 601. The slider 602 is connected to the rear shell 2 through an elastic member. The elastic member can be set as a compression spring 603. The compression spring 603 is set vertically, and the top end is fixed to the bottom of the slider 602, and the bottom end is fixed to the slide rail 205. Under the action of the compression spring 603, the slider 602 has a tendency to move upward, thereby compressing the spring sheet 4 to increase the convexity of the raised part of the spring sheet 4.

[0031] During use, when the user's hand feels lighter or the mobile phone is used on water, the adjustment protrusion 6021 is inserted into the upper card hole 601. Since the slider 602 has an upper limit sliding position, the distance between the protrusion 6021 and the upper limit sliding position is closer at this time, and the compression spring 603 drives the slider 602 to slide a shorter distance, so that the final distance between the two ends of the spring piece 4 is farther, and the convexity of the raised part of the spring piece 4 is smaller, thereby ensuring that the final bulge of the front transparent soft film 101 is smaller, which is suitable for the situation where the user's hand feels lighter or the mobile phone is used on water. Similarly, when the user has a heavy hand or the mobile phone is used underwater, the adjustment protrusion 6021 is inserted into the lower card hole 601. Since the slider 602 has an upper limit sliding position, the distance between the protrusion 6021 and the upper limit sliding position is relatively far. The compression spring 603 drives the slider 602 to slide a longer distance, so that the final distance between the two ends of the spring piece 4 is closer, and the convex part of the spring piece 4 is more convex, thereby ensuring that the final bulge of the front transparent soft film 101 is larger, which is suitable for the situation where the user has a heavy hand or the mobile phone is used underwater.

[0032] Similarly, when the user feels lighter, the adjustment protrusion 6021 is inserted into the upper card hole 601. Since the slider 602 has an upper limit sliding position, the distance between the protrusion 6021 and the upper limit sliding position is closer. At this time, the closer the distance between the protrusion 6021 and the upper limit sliding position is, the shorter the distance that the compression spring 603 can drive the slider 602 to slide, so that the final distance between the two ends of the spring piece 4 is farther, and the convexity of the convex part of the spring piece 4 is smaller, thereby ensuring that the final bulge of the front transparent soft film 101 is smaller, which is suitable for the user's lighter feel. Similarly, when the user's hand feels heavier or the phone is used deeper underwater, the adjustment protrusion 6021 is inserted into the lower card hole 601. Since the slider 602 has an upper limit sliding position, the distance between the protrusion 6021 and the upper limit sliding position is farther. At this time, the distance between the protrusion 6021 and the upper limit sliding position is farther, and the compression spring 603 drives the slider 602 to slide a longer distance, so that the final distance between the two ends of the spring piece 4 is closer, and the convex part of the spring piece 4 is more convex, ensuring that the final bulge of the front transparent soft film 101 is greater, adapting to the situation where the user feels heavier or the phone is used deeper underwater.

[0033] In a further embodiment, the compression spring 603 is an S-shaped structure. From a structural perspective, the S-shaped structure, through its continuous bending design, can achieve a longer telescopic stroke within a limited space: compared to a linear compression spring 603, under the same compression requirement, the S-shaped compression spring 603 has a shorter axial length, which can adapt to the compact installation space inside the rear housing 2, reduce the volume of the cavity 3, and avoid limiting the space for the mobile phone due to the installation of the compression spring 603.

[0034] At the same time, the S-shaped structure disperses stress distribution, allowing for the use of thinner wire while maintaining the same elastic coefficient, significantly reducing the weight of the compression spring 603 itself. This feature not only helps reduce the overall mass of the sealed and waterproof mobile phone case, improving portability, but also reduces the impact on the adjustment accuracy of the spring 4. When the lightweight compression spring 603 is combined with the slider 602, its own inertia will lessen the interference with the dynamic response of the adjustment mechanism 6, making the adjustment of the convexity of the spring 4 more precise and stable. This in turn ensures the precise control of the bulge of the front transparent soft film 101, better adapting to the different user feel and complex usage scenarios such as above and below the water.

[0035] In other embodiments, the elastic member may also be configured as a rubber matrix, which may be made of a highly elastic and ageing-resistant rubber material, and is connected between the slider 602 and the slide rail 205 to form a stable elastic support structure.

[0036] When the degree of protrusion of the spring piece 4 needs to be adjusted, the rubber matrix can provide continuous force through its own elastic deformation: in the natural state, the rubber matrix is ​​in a compressed state, applying an upward thrust to the slider 602, causing the protrusion 6021 and the card hole 601 to be tightly engaged, thereby maintaining the current protrusion degree of the spring piece 4; when the user manually adjusts the position of the slider 602, the rubber matrix produces corresponding compression deformation as the slider 602 slides, storing elastic potential energy. After the external force is removed, the rubber matrix releases the elastic potential energy to push the slider 602 upward to the upper limit sliding position, which not only ensures that the protrusion 6021 and the target card hole 601 are stably engaged, but also can maintain the current protrusion degree of the spring piece 4.

[0037] Compared with the compression spring 603, the rubber matrix has unique advantages: first, the rubber material itself has certain damping properties, which can effectively buffer vibration and impact during the sliding of the slider 602 and the force adjustment of the spring 4, avoid component wear caused by rigid collision, and extend the service life of the adjustment mechanism 6; second, the rubber matrix can be customized according to the shape of the installation space (such as made into a columnar, block or special-shaped structure), which is more suitable for the complex spatial layout inside the rear shell 2 and reduces the volume occupied by the cavity 3; third, the rubber material has good waterproof sealing properties, which can prevent water vapor from penetrating into the cavity 3 through the connection gap between the elastic part and other components, and synergize with the rear soft film 201, the front transparent soft film 101 and other structures to improve the overall waterproof performance.

[0038] In other embodiments, in order to achieve the snap connection between the pressure rod 5 and the front shell 1, a first snap-in groove 501 can also be provided on the front side wall of the bottom end of the pressure rod 5, and a snap-in portion 7 is provided on the bottom front side wall of the front shell 1. The snap-in portion 7 is made of elastic material, such as rubber, and is an L-shaped structure, and has a vertically connected horizontal section and a vertical section, wherein the rear end of the horizontal section is vertically inserted into the front shell 1, and the vertical section is vertically downward and can be snap-connected with the first snap-in groove 501, thereby enhancing the connection stability between the rear shell 2 and the front shell 1.

[0039] In other embodiments, the clamping portion 7 is a rigid structure, and the clamping portion 7 can rotate around the axis of its own horizontal section, and has corresponding locked and unlocked states before and after rotation. When in the locked state, the vertical section of the clamping portion 7 is clamped with the first clamping slot 501, thereby enhancing the connection stability between the rear shell 2 and the front shell 1; when in the unlocked state, the clamping portion 7 and the first clamping slot 501 are disengaged, so that the pressure rod 5 can rotate freely, facilitating the disassembly operation.

[0040] In other embodiments, in order to improve the ease of disassembly, a slot 202 is provided at the top of the rear shell 2 to ensure that the slot 202 is close to the hinge point between the pressure rod 5 and the front shell 1; a spring protrusion 502 is fixedly provided at the bottom of the top end of the pressure rod 5, and the spring protrusion 502 is inserted into the slot 202 when the pressure rod 5 is rotated to be sleeved on the front shell 1 and the rear shell 2.

[0041] When the cavity 3 needs to be opened, the pressure rod 5 is driven to rotate in a direction away from the rear housing 2. During the rotation of the pressure rod 5, the pressure rod 5 drives the elastic projection 502 to move synchronously. When the elastic projection 502 abuts against the slot 202, as the pressure rod 5 continues to rotate, the elastic projection 502 pushes the rear housing 2 to move backward, thereby achieving automatic separation of the front housing 1 and the rear housing 2, improving the ease of operation.

[0042] In other embodiments, in order to charge the mobile phone, a charging port 102 is opened at the bottom of the front shell 1, and the charging port 102 is connected to the cavity 3, and a plug 8 is sealed at the charging port 102; the setting of the plug 8 can prevent water from entering the cavity 3 through the charging port 102, resulting in waterproof failure; when the mobile phone needs to be charged, the plug 8 can be removed, and then the charging cable can be passed through the charging port 102 and connected to the mobile phone, so as to realize charging of the mobile phone.

[0043] In other embodiments, in order to avoid the loss of the plug 8, the rear end of the plug 8 is elastically hinged to the bottom of the rear shell 2 through a torsion spring. Under the action of the torsion spring, the plug 8 has a tendency to rotate toward the charging port 102, thereby achieving continuous blocking of the charging port 102, which is beneficial to ensuring the sealing performance; when the mobile phone needs to be charged, the plug 8 can be driven to rotate away from the charging port 102, and then the charging cable can be passed through the charging port 102 and connected to the mobile phone, thereby realizing charging of the mobile phone. At this time, since the plug 8 and the rear shell 2 are hinged, it can be avoided from being lost.

[0044] In a further embodiment, in order to improve the sealing effect at the charging port 102, the front end of the plug 8 can be bent upward, and an elastic fixing protrusion 801 is fixedly provided on the rear side wall of the bending part, and a fixing groove is provided on the bottom front side wall of the front shell 1. The fixing protrusion 801 can be snapped into the fixing groove during installation, thereby connecting the plug 8 and the front shell 1, which helps to improve the sealing effect of the plug 8 at the charging port 102.

[0045] In other embodiments, in order to improve the sealing effect at the charging port 102, an elastic protrusion can be provided on the top of the plug 8, and the elastic protrusion can be inserted into the charging port 102 with interference fit, so that the gap between the charging port 102 and the plug 8 can be reduced through the elastic deformation of the elastic protrusion, thereby helping to improve the sealing effect of the plug 8 on the charging port 102.

[0046] In other embodiments, in order to expand the function of the pressure rod 5 and make it also serve as a mobile phone holder, the hinge structure between the top end of the pressure rod 5 and the front shell 1 is set to a friction hinge.

[0047] Specifically, an interference fit is employed between the hinged end of the lever 5 and the front housing 1, thereby creating a damping effect through static friction between the contact surfaces. When an external force is applied to rotate the lever 5, friction counteracts the weight of the lever 5 itself and the phone's housing, allowing the lever 5 to maintain a stable static position even after rotation to any angle. This position lock can be achieved without the need for additional locking components, thereby providing support at any angle for a phone placed within the cavity 3. This friction hinge design synergizes with the original function of the lever 5: when the lever 5 is engaged with the front housing 1, its rigid fit with the front and rear housings 1 and 2 partially offsets external forces, with friction damping primarily providing auxiliary stabilization. When the lever 5 is used as a phone holder, once released from the front housing 1, friction damping becomes the core force maintaining its support angle, ensuring that the phone does not shift due to its own weight when tilted (e.g., when watching a movie or making a video call).

[0048] Compared with setting up a bracket structure separately, the advantages of the pressure rod 5 as a mobile phone holder are: first, there is no need to add additional parts, and the function expansion is achieved by using the structure of the pressure rod 5 itself, which simplifies the overall structure of the mobile phone shell and reduces the weight; second, the damping force of the friction hinge can be precisely controlled by adjusting the roughness and interference of the hinge surface, which can not only ensure the stability during support (avoiding angle changes caused by slight touches), but also ensure the smoothness of the operation when the user adjusts the angle (it can be rotated without excessive external force); third, the length and shape of the pressure rod 5 are adapted to the mobile phone shell. When used as a bracket, it can provide support that fits the contour of the shell more closely, reduce the space occupied in the folded or unfolded state, and improve the convenience of carrying.

[0049] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and modifications are possible without departing from the scope of the present invention, and such variations and modifications are fully within the scope of protection of the present invention.
