Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a protective case and an electronic device having the protective case. Background Technology

[0002] With the development of technology, electronic devices have become increasingly powerful, and the demand for their use has also increased, such as watching movies and videos, taking photos and recording videos. To free up users' hands, protective cases for electronic devices are equipped with stands to support them on desktops or other surfaces. However, common stands can only support electronic devices in a fixed direction, failing to meet the needs of diverse users. Utility Model Content

[0003] Therefore, it is necessary to provide a protective case and an electronic device with a protective case, which can support the electronic device from multiple angles to meet the usage needs of different users.

[0004] In a first aspect, this application provides a protective shell, comprising:

[0005] A housing for placement on the exterior of an electronic device;

[0006] A support frame is rotatably connected to the housing. The support frame can rotate around the length of the housing to have an extended state and a retracted state. In the extended state, the support frame and the housing can be set at different angles, and the support frame can support the housing at different support angles. In the retracted state, the support frame is retracted into the housing.

[0007] A hinge component, comprising a fixed part, a movable part, and a connecting shaft, wherein the fixed part is fixed to the housing, the movable part is connected to the support frame, and the movable part is rotatably connected to the fixed part via the connecting shaft; the movable part includes a movable seat and a first bushing, the first bushing being disposed on the movable seat and sleeved on the connecting shaft, and the outer surface of the first bushing having a plurality of limiting grooves; and

[0009] In the aforementioned protective case, the support frame is normally in a folded state, with the limiting member separated from the limiting slot. If the electronic device needs to be supported on a table, the support frame can be rotated along the length of the case, allowing the limiting member to engage with different limiting slots, thus limiting the support frame to different support angles. In this way, the support frame can provide multi-angle support for the electronic device, meeting the needs of different users.

[0010] In one embodiment, the limiting groove is a strip groove, all of which extend along the axial direction of the first bushing and are spaced apart circumferentially along the first bushing; or, the limiting groove is a circular groove, all of which are spaced apart circumferentially along the first bushing.

In this way, the support frame can provide multi-angle support for the electronic device, meeting the needs of different users.

[0018] In one embodiment, the limiting structure includes a first limiting sleeve, which is sleeved on the connecting shaft and directly connected to the first end face of the first bushing.

Multiple first limiting teeth are provided, spaced apart circumferentially along the first bushing. And / or, multiple second limiting teeth are provided, spaced apart circumferentially along the first limiting sleeve. In the unfolded state, the first limiting teeth and second limiting teeth engage to hold the support frame at different support angles.

[0019] In one embodiment, the first limiting sleeve includes a first cylindrical body and a second cylindrical body. The first cylindrical body is disposed near the first end face of the first bushing, and the second cylindrical body is disposed on the side of the first cylindrical body away from the first bushing. The second limiting tooth is disposed on the end face of the first cylindrical body facing the first end face of the first bushing. The end face of the first cylindrical body facing the second cylindrical body is provided with a third limiting tooth. There are multiple third limiting teeth, which are spaced apart circumferentially along the first cylindrical body. The second limiting tooth is staggered from the third limiting tooth. The end face of the second cylindrical body facing the first cylindrical body is provided with a fourth limiting tooth that meshes with the third limiting tooth.

[0020] In one embodiment, the protective shell further includes a second elastic element, one end of which is connected to the first limiting sleeve, and the other end of which is connected to the fixing part.

Under the action of the third elastic element, the second limiting sleeve can move axially along the connecting shaft.

[0023] In one embodiment, the protective shell further includes a torsion spring disposed on the connecting shaft, one end of the torsion spring being connected to the fixed part and the other end of the torsion spring being connected to the movable part; the protective shell further includes a locking structure, which, in the retracted state, is used to lock the support frame to the shell.

[0027] Thirdly, this application also provides an electronic device with a protective shell, including a device body and the aforementioned protective shell, wherein the protective shell is disposed outside the device body.

[0028] In the aforementioned electronic device, the support frame is typically in a folded state.

Detailed Implementation

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] One embodiment of this application provides an electronic device with a protective shell 10, including a device body and a protective shell 10, wherein the protective shell 10 is disposed on the outside of the device body.

[0049] It should be noted that when the protective case 10 is not needed, the user can remove the protective case 10 from the device. Therefore, the electronic device has two states: one is that the device is wearing the protective case 10, which prevents the device from being dropped and damaged; the other is that the device is not wearing the protective case 10.

[0050] The device itself can be a power bank, mobile phone, or tablet computer, and is not limited to these.

[0051] The protective shell 10 can be designed according to the shape of the equipment body, so that the shape and size of the protective shell 10 are adapted to the equipment body.

[0052] In one embodiment, see Figure 1 and Figure 4 The protective shell 10 includes a shell 11, a support frame 12, and a limiting structure 13.

[0053] Optionally, see Figure 1 The housing 11 includes a back cover 111 and a side frame 112, with the side frame 112 connected to the edge of the back cover 111. Thus, the housing 11 can be fitted onto the device body. When the protective case 10 is fitted onto a mobile phone or tablet computer with a display screen, the back cover 111 faces the side of the device body away from the display screen.

[0054] Of course, in other embodiments, if the device body is a power bank, the housing 11 may only include a back cover 111, which is located on the outside of the power bank.

[0055] See Figure 1 and Figure 2 The support frame 12 has a connecting end 121 and a free end 122. The connecting end 121 is rotatably connected to the back cover 111. The support frame 12 can be rotated around the length of the back cover 111, so that the support frame 12 has an unfolded state and a folded state. For ease of understanding, S1 is used to represent the length direction of the back cover 111. See reference. Figure 1 , Figure 7 and Figure 13 In the unfolded state, the support frame 12 and the back cover 111 can be set at different angles, allowing the support frame 12 to support the housing 11 at different angles. (See reference...) Figure 2 and Figure 8 In the folded state, the support frame 12 is folded into the back cover 111.

[0056] Understandably, see Figure 1 The support frame 12 can be rotated relative to the housing 11 to change the angle between the support frame 12 and the back cover 111, thereby changing the support angle of the support frame 12 and giving the support frame 12 multiple support angles.

[0057] See Figure 1 and Figure 4 The limiting structure 13 is used to limit the support frame 12 so that the support frame 12 can be positioned at different support angles.

[0058] Normally, the support frame 12 is in a folded state. When it is necessary to support the electronic device on a table, the support frame 12 is rotated along the length of the back cover 111, causing the free end 122 of the support frame 12 to rotate away from the back cover 111 until the support frame 12 is adjusted to a suitable support angle. The limiting structure 13 then limits the support frame 12, positioning it at the appropriate support angle. In this way, the support frame 12 can provide multi-angle support for the electronic device, meeting the needs of different users.

[0059] If no support for the electronic device is required, the support frame 12 is flipped in the opposite direction along the length of the back cover 111, so that the free end 122 of the support frame 12 is flipped toward the back cover 111 until the support frame 12 is retracted into the back cover 111. In this way, the support frame 12 can be prevented from interfering with the use of the electronic device.

[0060] In one embodiment, see Figure 1 The back cover 111 has a first end 1111 and a second end 1112, which are the two ends along the length of the back cover 111. The first end 1111 has a clearance hole 1114 for avoiding the camera of the device body. The support frame 12 is located at the second end 1112. This avoids interference between the support frame 12 and the camera. Furthermore, in the unfolded state, the support frame 12 can support not only the horizontally placed device body but also the vertically placed device body.

[0061] In one embodiment, see Figure 1 The back cover 111 has a receiving slot 1113 on the side opposite to the main body of the device.

[0062] See Figure 1 In its unfolded state, the support frame 12 is located outside the receiving slot 1113, thus enabling the unfolded support frame 12 to support electronic equipment. (See attached image) Figure 2 In the folded state, the support frame 12 is located in the receiving slot 1113, which avoids the support frame 12 from interfering with the use of electronic equipment.

[0063] In this embodiment, in the folded state, refer to... Figure 2The side of the support frame 12 facing away from the bottom of the receiving groove 1113 is flush with the side of the back cover 111 facing away from the device body. The support frame 12 can be completely retracted into the receiving groove 1113. When the protective case 10 is placed on a horizontal table (with the back cover 111 and the back cover of the device body facing the table), in the retracted state, the height of the side of the support frame 12 exposed outside the receiving groove 1113 from the table is no higher than the maximum height of the protective case 10 from the table. Thus, when the support 12 is in the retracted state, the support frame 12 will not scratch the user's hand, nor will it cause bumps to the back panel of the device body due to unevenness of the back cover, while also improving user comfort.

[0064] In one embodiment, see Figure 5 The protective shell 10 also includes a hinge component 14, which includes a fixed part 141, a movable part 142, and a connecting shaft 143. The fixed part 141 is fixed to the back cover 111. Optionally, see [reference needed]. Figure 3 The fixing part 141 is fixed to one side of the back cover 111 having the side frame 112. (See reference...) Figure 4 The movable part 142 is connected to the connecting end 121 of the support frame 12.

[0065] Optionally, the support frame 12 and the movable part 142 can be connected by means including but not limited to riveting, hot melting, bonding and screw fixing.

[0066] Further, see Figure 5 The movable part 142 is rotatably connected to the fixed part 141 via a connecting shaft 143. It is understood that the movable part 142 is connected to the connecting shaft 143, and the fixed part 141 is rotatably connected to the connecting shaft 143. Thus, a hinge 14 is used to foldably connect the support frame 12 to the back cover 111.

[0067] In one embodiment, see Figure 5 The movable part 142 includes a movable seat 1421 and a first bushing 1422 connected to the movable seat 1421. The first bushing 1422 is sleeved on and connected to the connecting shaft 143. The fixed part 141 includes a fixed seat 1411 and a second bushing 1412 connected to the fixed seat 1411. The second bushing 1412 is sleeved on and rotatably connected to the connecting shaft 143. Thus, the fixed part 141 and the movable part 142 are rotatably connected.

[0068] In this embodiment, there are two first bushings 1422 and two second bushings 1412. The two first bushings 1422 are sleeved on the connecting shaft 143 and spaced apart along the axial direction of the connecting shaft 143. The two second bushings 1412 are sleeved on the connecting shaft 143 and spaced apart along the axial direction of the connecting shaft 143.

[0069] In one embodiment, see Figure 5 The limiting structure 13 is provided on the fixing part 141. In the unfolded state, the limiting structure 13 is engaged with the first bushing 1422. Of course, in other embodiments, the limiting structure 13 may also be engaged with the connecting shaft 143.

[0070] In one embodiment, see Figure 5 and Figure 6 The outer surface of the first bushing 1422 is provided with a plurality of limiting grooves 14223. Optionally, all the limiting grooves 14223 are strip grooves, all the limiting grooves 14223 extend along the axial direction, and all the limiting grooves 14223 are spaced apart along the circumference of the first bushing 1422.

[0071] Optionally, all the limiting grooves 14223 are circular grooves, and all the limiting grooves 14223 are spaced apart along the circumference of the first bushing 1422.

[0072] Further, see Figure 5 and Figure 6 The limiting structure 13 includes a limiting member 131, which is disposed on the fixing part 141. In the folded state, the limiting member 131 is separated from the limiting groove 14223, so the limiting structure 13 does not limit the support frame 12. In the unfolded state, the limiting member 131 engages with the multiple limiting grooves 14223.

[0073] When the aforementioned protective case 10 needs to support the electronic device on a desktop, it can be flipped around the length of the back cover 111, allowing the limiting member 131 to engage with the limiting grooves 14223 at different positions, thereby limiting the support frame 12 to different support angles. In this way, the support frame 12 can support the electronic device at multiple angles, meeting the usage needs of different users.

[0074] In one embodiment, see Figure 5 and Figure 6 The limiting member 131 is movably disposed in the fixing part 141. Specifically, the fixing base 1411 is provided with a sliding groove 14111, the limiting member 131 is movably disposed in the sliding groove 14111, the sliding groove 14111 has a first opening 14113 on the side wall near the connecting shaft 143, and a second opening 14114 on the side wall away from the connecting shaft 143.

[0075] Further, see Figure 5 and Figure 6 The protective shell 10 also includes a first elastic member 15. One end of the first elastic member 15 is connected to the fixing part 141, and the other end of the first elastic member 15 is connected to the limiting member 131. Under the action of the first elastic member 15, the limiting member 131 can be inserted into and withdrawn from the limiting groove 14223.

[0076] Optionally, refer to Figure 5 and Figure 6 The fixed base 1411 is also provided with a receiving groove 14112, which is connected to the sliding groove 14111 through the second opening 14114. The first elastic member 15 is provided in the receiving groove 14112, and the first elastic member 15 abuts against the groove wall of the receiving groove 14112. The first elastic member 15 abuts against the limiting member 131 through the second opening 14114.

[0077] When the limiting member 131 contacts the circumferential surface of the first bushing 1422, the first elastic member 15 is in a compressed state. When the support frame 12 rotates to the point where the limiting groove 14223 is opposite to the limiting member 131, the first elastic member 15 pushes the limiting member 131 closer to the first bushing 1422, so that the limiting member 131 is inserted into the limiting groove 14223 through the first opening 14113, realizing the limiting engagement between the limiting member 131 and the limiting groove 14223. In this way, the reliability of the limiting engagement between the limiting member 131 and the limiting groove 14223 can be guaranteed by the abutment of the first elastic member 15. At the same time, the first elastic member 15 can play a buffering role, avoiding hard compression between the limiting member 131 and the connecting shaft 143, which would cause wear on the limiting member 131 and the connecting shaft 143, thus helping to extend the service life.

[0078] In one embodiment, see Figure 5 and Figure 6 Both the limiting member 131 and the first elastic member 15 are provided.

[0079] Further, see Figure 5 and Figure 6 The first elastic element 15 is a V-shaped retaining spring, which is disposed in the receiving groove 14112. The V-shaped retaining spring has a first elastic arm 151 and a second elastic arm 152 connected to the first elastic arm 151. The first elastic arm 151 abuts against the groove wall of the receiving groove 14112, and the second elastic arm 152 abuts against the limiting element 131 through the second opening 14114.

[0080] In another embodiment, see [reference] Figure 11 and Figure 12 Both first bushings 1422 are provided with multiple limiting grooves 14223.

[0081] Further, see Figure 11 and Figure 12 Two limiting members 131 are provided, and the two limiting members 131 are respectively configured to correspond one-to-one with the two first bushings 1422. Specifically, two sliding grooves 14111 are provided, and the two sliding grooves 14111 are respectively configured to correspond one-to-one with the two first bushings 1422. The two limiting members 131 are movably disposed in the two sliding grooves 14111.

[0082] Further, see Figure 12The first elastic element 15 is provided, with one end of the first elastic arm 151 facing away from the second elastic arm 152 abutting against one of the limiting elements 131, and the other end of the second elastic arm 152 facing away from the first elastic arm 151 abutting against the other limiting element 131. The connection between the first elastic arm 151 and the second elastic arm 152 abuts against the wall of the receiving groove 14112. Thus, in the unfolded state, the two limiting elements 131 and the two first bushings 1422 engage in limiting cooperation, which can better limit the support frame 12, thereby ensuring the stability of the support frame 12 in supporting the electronic equipment.

[0083] In one embodiment, see 5. Figure 6 and Figure 12 The protective shell 10 also includes a torsion spring 16. The torsion spring 16 is located on the connecting shaft 143, with one end of the torsion spring 16 abutting against the fixed part 141 and the other end abutting against the movable part 142. In this way, the torsion spring 16 can provide sufficient rebound force to help the support frame 12 switch to the unfolded state more easily. In addition, the torsion spring 16 can also play a role in cushioning and vibration reduction.

[0084] In one embodiment, see Figure 2 , Figure 3 and Figure 9 The protective housing 10 also includes a locking structure 19. In the retracted state, the locking structure 19 locks the support frame 12 to the housing 11, preventing the support frame 12 from rotating relative to the housing 11, thus keeping the support frame 12 in the retracted state and preventing the support frame 12 from interfering with the use of electronic equipment. When the locking structure 19 is released, the support frame 12 can rotate relative to the housing 11.

[0085] In one embodiment, see Figure 2 and Figure 4 The support frame 12 is provided with a locking groove 1221. Optionally, the locking groove 1221 is provided at the free end 122 of the support frame 12. The housing 11 is provided with a mounting hole 1121, which is optionally provided at the side frame 112.

[0086] Further, see Figure 2 and Figure 3 The locking structure 19 includes a pressing member 191 and a locking tongue 192. The pressing member 191 is movably disposed in the mounting hole 1121, and the locking tongue 192 is movably disposed on the back cover 111. The locking tongue 192 has a locked position and an unlocked position. In the locked position, the locking tongue 192 extends and is inserted into the lock groove 1221. In the unlocked position, the locking tongue 192 retracts and separates from the support frame 12.

[0087] In the closed state, the pressing member 191 abuts against the locking tongue 192 via the elastic reset member. The locking tongue 192 is inserted into the locking groove 1221 to lock the support frame 12. At this time, the support frame 12 cannot be rotated relative to the housing 11. When it is necessary to release the lock, an external force is applied to the pressing member 191. The pressing member 191 drives the locking tongue 192 to switch to the release position by pressing. The locking tongue 192 separates from the support frame 12, and the torsion spring 16 pushes the support frame 12 to rotate around the length direction of the back cover 111.

[0088] Of course, in other embodiments, see [reference] Figure 9 and Figure 10 The support frame 12 is slidably connected to the movable part 142, and the support frame 12 can slide relative to the movable part 142 in a direction closer to or farther from the connecting shaft 143. The locking structure 19 includes a first locking part 193 and a second locking part 194. The first locking part 193 is disposed on the support frame 12, and the second locking part 194 is disposed on the fixed base 1411. In the closed state, the first locking part 193 and the second locking part 194 are locked together. In the unfolded state, the first locking part 193 and the second locking part 194 are separated.

[0089] Further, see Figure 10 One of the first locking part 193 and the second locking part 194 is provided with a locking groove 1931, which extends along the sliding direction of the support frame 12. The other of the first locking part 193 and the second locking part 194 includes a locking protrusion 1941. In the closed state, the locking protrusion 1941 abuts against the groove wall of the locking groove 1931. In the unfolded state, the locking protrusion 1941 separates from the groove wall of the locking groove 1931, and the torsion spring 16 pushes the support frame 12 to rotate around the length direction of the back cover 111.

[0090] In this embodiment, a receiving groove 1113 is provided on a fixed base 1411, and locking protrusions 1941 are provided on both sides of the receiving groove 1113 along the sliding direction of the support frame 12. Locking grooves 1931 are provided on both sides of the support frame 12. In the retracted state, the locking protrusions 1941 abut against the groove wall of the locking groove 1931 away from the connecting shaft 143. When the support frame 12 moves away from the connecting shaft 143, the locking protrusions 1941 separate from the groove wall of the locking groove 1931.

[0091] In another embodiment, see [reference] Figure 14 and Figure 15 The protective shell 10 includes a shell 11, a support frame 12, a limiting structure 13, and a hinge component 14. The structure in which the shell 11 is rotatably connected to the support frame 12 via the hinge component 14 is the same as in the above embodiment.

[0092] Furthermore, the first bushing 1422 has a first end face and a second end face, which are two opposite end faces of the first bushing 1422 along its axial direction. The first end face is provided with a first limiting tooth 14221. A limiting structure 13 is provided on the connecting shaft 143. In the unfolded state, the limiting structure 13 cooperates with the first limiting tooth 14221 to hold the support frame 12 at different support angles.

[0093] The aforementioned protective shell 10 typically has the support frame 12 in a folded state. When the electronic device needs to be supported on a table, the support frame 12 can be rotated along the length of the shell 11, allowing the limiting structure 13 to engage with the first limiting tooth 14221, thereby limiting the support frame 12 to different support angles. In this way, the support frame 12 can provide multi-angle support for the electronic device, meeting the needs of different users.

[0094] In one embodiment, see Figure 15 and Figure 16 The limiting structure 13 includes a first limiting sleeve 133, which is located on the side of the first end face away from the second end face and sleeved on the connecting shaft 143. The end face of the first limiting sleeve 133 facing the first bushing 1422 is provided with a second limiting tooth 13311 that cooperates with the first limiting tooth 14221 for limiting.

[0095] Among them, see Figure 15 and Figure 16 Multiple first limiting teeth 14221 are provided, and all first limiting teeth 14221 are spaced apart circumferentially along the first bushing 1422. And / or, multiple second limiting teeth 13311 are provided, and all second limiting teeth 13311 are spaced apart circumferentially along the first limiting sleeve 133. When the support frame 12 is in the unfolded state and rotates around the length direction of the back cover 111, the first limiting teeth 14221 engage with the second limiting teeth 13311 at different positions, thereby limiting the support frame 12 at different support angles.

[0096] In one embodiment, see Figure 15 and Figure 16The first limiting sleeve 133 includes a first cylindrical body 1331 and a second cylindrical body 1332. The first cylindrical body 1331 is located near the first bushing 1422. The cross-sectional shape of the portion of the connecting shaft 143 corresponding to the first cylindrical body 1331 is flat or polygonal. The cross-sectional shape of the inner surface of the first cylindrical body 1331 matches the cross-sectional shape of the connecting shaft, allowing the first cylindrical body 1331 to move only along the axial direction of the connecting shaft 143. The second cylindrical body 1332 is located on the side of the first cylindrical body 1331 away from the first bushing 1422. The cross-sectional shape of the portion of the connecting shaft 143 corresponding to the second cylindrical body 1332 is circular, and the outer diameter of the portion of the connecting shaft 143 corresponding to the second cylindrical body 1332 is adapted to the inner diameter of the second cylindrical body 1332, allowing the second cylindrical body 1332 to move not only along the axial direction of the connecting shaft 143 but also to rotate around the axial direction of the connecting shaft 143. The second limiting tooth 13311 is provided on one end face of the first cylinder 1331 facing the first bushing 1422. The first cylinder 1331 is provided on one end face of the second cylinder 1332. There are multiple third limiting teeth 13312. All the third limiting teeth 13312 are spaced apart along the circumference of the first cylinder 1331, and the second limiting teeth 13311 and the third limiting teeth 13312 are staggered.

[0097] Further, see Figure 15 and Figure 16 The second cylindrical body 1332 is connected to the movable part 142. Specifically, the movable part 142 is provided with an insertion groove 14211, and the outer peripheral surface of the second cylindrical body 1332 is provided with a protrusion 13322, which is located in the insertion groove 14211 to realize the connection between the second cylindrical body 1332 and the movable part 142. The end face of the second cylindrical body 1332 facing the first cylindrical body 1331 is provided with a fourth limiting tooth 13321, and the third limiting tooth 13312 meshes with the fourth limiting tooth 13321.

[0098] In use, the support frame 12 is flipped around the length of the back cover 111, and the first limiting tooth 14221 engages with the second limiting tooth 13311. That is, the first limiting tooth 14221 is located within the tooth groove formed by two adjacent second limiting teeth 13311, so as to adjust and fix the support angle of the support frame 12. Since the second limiting tooth 13311 and the third limiting tooth 13312 are staggered, during the engagement of the first limiting tooth 14221 and the second limiting tooth 13311, the tip of the third limiting tooth 13312 abuts against the tip of the fourth limiting tooth 13321.

[0099] Continuing to rotate the support frame 12 along the length of the back cover 111, the tip of the first limiting tooth 14221 abuts against the tip of the second limiting tooth 13311, while the third limiting tooth 13312 meshes with the fourth limiting tooth 13321. That is, the fourth limiting tooth 13321 is located within the tooth groove formed by the two adjacent third limiting teeth 13312, in order to adjust and fix the support angle of the support frame 12. Since the second cylinder 1332 is connected to the support frame 12 through the movable part 142, the meshing of the third limiting tooth 13312 and the fourth limiting tooth 13321 also enables the adjustment and fixation of the support angle of the support frame 12.

[0100] Thus, in this embodiment, the first limiting sleeve 133 includes a first cylindrical body 1331 and a second cylindrical body 1332. The two end faces of the first cylindrical body 1331 are respectively provided with multiple second limiting teeth 13311 and multiple third limiting teeth 13312. The second limiting teeth 13311 and the third limiting teeth 13312 are staggered, allowing for multiple positioning positions. This enables the support frame 12 to be positioned at a better support angle, while also allowing the first limiting sleeve 133 to be implemented in a small volume, thus reducing the thickness of the protective shell 10. Furthermore, because the second limiting teeth 13311 and the third limiting teeth 13312 are staggered, multiple high-strength limiting points can be achieved on the small-volume connecting shaft 143, improving the stability and lifespan of the support frame 12 in supporting electronic devices.

[0101] In one embodiment, see Figure 15 and Figure 16 The protective shell 10 also includes a second elastic element 17. The second elastic element 17 is disposed between the first limiting sleeve 133 and the second bushing 1412. Specifically, one end of the second elastic element 17 is connected to the end face of the second cylinder 1332 opposite to the first cylinder 1331, and the other end of the second elastic element 17 is connected to the second bushing 1412. Thus, under the extension and retraction of the second elastic element 17, the first limiting tooth 14221 can engage and disengage with the second limiting tooth 13311, and the third limiting tooth 13312 can engage and disengage with the fourth limiting tooth 13321.

[0102] Further, see Figure 15 The second elastic element 17 is sleeved on the connecting shaft 143. In this way, the connecting shaft 143 can guide the extension and retraction of the second elastic element 17, making the extension and retraction of the second elastic element 17 directional, improving the stability of the meshing between the first limiting tooth 14221 and the second limiting tooth 13311, and between the third limiting tooth 13312 and the fourth limiting tooth 13321, thereby ensuring the stability of the support frame 12 in supporting the electronic equipment.

[0103] In one embodiment, see Figure 15 and Figure 16The second end face is provided with a fifth limiting tooth 14222.

[0104] Further, see Figure 15 and Figure 16 The limiting structure 13 also includes a second limiting sleeve 134. The second limiting sleeve 134 is located on the side of the second end face away from the first end face and is sleeved on the connecting shaft 143. The end face of the second limiting sleeve 134 facing the first bushing 1422 is provided with a sixth limiting tooth 1341.

[0105] The fifth limiting teeth 14222 are provided in multiple ways, and all the fifth limiting teeth 14222 are arranged circumferentially along the first bushing 1422. And / or, the sixth limiting teeth 1341 are provided in multiple ways, and all the sixth limiting teeth 1341 are arranged circumferentially along the second limiting sleeve 134.

[0106] Thus, the sixth limiting tooth 1341 can engage with the fifth limiting tooth 14222 at different positions to adjust and fix the support angle of the support frame 12. In addition, when the fifth limiting tooth 14222 engages with the sixth limiting tooth 1341, a clicking sound can be generated to help the user determine the rotation angle of the support frame by sound, and also enhance the user's enjoyment.

[0107] In one embodiment, see Figure 15 and Figure 16 The cross-sectional shape of the part of the connecting shaft 143 corresponding to the second limiting sleeve 134 is flat or polygonal. The cross-sectional shape of the inner surface of the second limiting sleeve matches the cross-sectional shape of the connecting shaft, so that the second limiting sleeve 134 can only move along the axial direction of the connecting shaft 143.

[0108] Further, see Figure 15 and Figure 16 The protective shell 10 also includes a third elastic element 18. The third elastic element 18 is disposed between the second limiting sleeve 134 and the second bushing 1412. One end of the third elastic element 18 is connected to the end of the second limiting sleeve 134 opposite to the first bushing 1422, and the other end of the third elastic element 18 is connected to the second bushing 1412. Thus, under the extension and retraction of the third elastic element 18, the fifth limiting tooth 14222 can engage and disengage with the sixth limiting tooth 1341.

[0109] Further, see Figure 15 The third elastic element 18 is sleeved on the connecting shaft 143. In this way, the connecting shaft 143 can guide the extension and retraction of the third elastic element 18, making the extension and retraction of the third elastic element 18 directional, improving the stability of the meshing between the fifth limiting tooth 14222 and the sixth limiting tooth 1341, thereby ensuring the stability of the support frame 12 in supporting the electronic equipment.

[0111] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0112] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0113] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0114] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0115] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0116] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
