[0013] In an optional embodiment, the movable locking hook has a holding portion for restraining the mobile terminal and a hinge portion that is hinged to the back panel assembly.

[0014] The movable locking hook is slidably engaged with the housing assembly. During the process of the back plate assembly rotating from the locked position to the unlocked position, the movable locking hook rotates around the hinge in the first direction under the action of the housing assembly until the holding part retracts below the supporting surface.

[0015] In an optional embodiment, one of the backplate assembly and the housing assembly has a sliding portion, and the other has a guide groove extending in the rotation plane of the backplate assembly. The sliding portion slides into the guide groove, and the extending direction of the guide groove forms an angle with the trajectory of the hinge portion as it moves with the backplate assembly.

[0016] In an optional embodiment, the backplate assembly is further provided with a first elastic element, which acts on the movable locking hook. Under the action of the first elastic element, the movable locking hook tends to rotate in a second direction, which is opposite to the first direction.

[0017] In an optional embodiment, the housing assembly is provided with a locking module, which is used to lock the back panel assembly when the back panel assembly moves to the locking position, so as to keep the back panel assembly in the locking position.

[0018] In an optional embodiment, the housing assembly is further provided with a damping module, which is connected to the back plate assembly and is used to drive the back plate assembly to the unlocked position after the locking module releases the locking of the back plate assembly.

[0019] In an optional embodiment, the damping module includes a base, a slider, and a second elastic element. The base is disposed on the housing assembly, the slider is slidably engaged with the base, and the slider is connected to the back plate assembly.

[0020] The second elastic element is disposed between the slider and the base, and is used to push the slider relative to the base to slide after the locking module releases the locking of the back plate assembly, so as to drive the back plate assembly to the unlock position.

[0021] In an optional embodiment, the backplate assembly is hinged to the housing assembly;

[0022] One of the backplate assembly and the slider has a strip-shaped hole extending in the rotation plane of the backplate assembly, and the other has a sliding boss that slides in conjunction with the strip-shaped hole.

[0023] In an optional embodiment, one of the base and the slider is provided with a reduction gear, and the other is provided with a fixed gear. The fixed gear meshes with the reduction gear, and the reduction gear rotates relative to the fixed gear during the sliding of the slider relative to the base.

[0024] In an optional embodiment, the slider has a limiting portion and the base has a stop portion, the stop portion being used to abut against the limiting portion so that the back plate assembly is held in the unlocked position under the action of the second elastic member.

[0025] In an optional embodiment, the backplate assembly is further provided with a plurality of magnetic elements, which are respectively located at a plurality of different parts of the backplate assembly, for magnetically attracting the mobile terminal at the plurality of different parts of the backplate assembly to guide the mobile terminal to remain in a fixed position on the support surface.

[0026] In an optional embodiment, the backplane assembly is further provided with a charging module for charging the mobile terminal.

[0027] Compared to existing technologies, the mobile terminal fixing device provided by this utility model allows the back plate assembly to move between a locked position and an unlocked position relative to the outer shell assembly.

[0065] Example

[0066] Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a structural schematic of the mobile terminal fixing device 100 provided in this embodiment. Figure 2 The diagram shown is an exploded view of the mobile terminal fixing device 100.

[0067] The mobile terminal fixing device 100 provided in this embodiment includes a housing assembly 110, a back plate assembly 120, and a movable locking hook 130. The housing assembly 110 can be installed in any location inside a vehicle, such as the armrest box, dashboard, pillar, seat, or door panel. The back plate assembly 120 is disposed on the housing assembly 110 and is used to support a mobile terminal 200 such as a mobile phone or tablet. The movable locking hook 130 is installed on the housing assembly 110 or the back plate assembly 120 and is used to restrain the mobile terminal 200 on the back plate assembly 120.

[0068] In this embodiment, a fixed locking hook 122 is provided on the back plate assembly 120. The fixed locking hook 122 is used to clamp the mobile terminal 200 together with the movable locking hook 130. In order to reduce the difficulty of assembling and disassembling the mobile terminal 200 and facilitate the use of the mobile terminal 200, in this embodiment, the back plate assembly 120 is movably disposed on the outer shell assembly 110 and can move relative to the outer shell assembly 110 between a locked position and an unlocked position.

[0069] The back panel assembly 120 has a support surface 121 for supporting the mobile terminal 200. When the back panel assembly 120 moves to the locked position, the movable locking hook 130 extends at least partially from the support surface 121 to restrain the mobile terminal 200, i.e., it clamps and fixes the mobile terminal 200 together with the fixed locking hook 122. When the back panel assembly 120 moves to the unlocked position, the movable locking hook 130 retracts at least partially below the support surface 121 to release the restraint on the mobile terminal 200.

[0070] The back panel assembly 120 can move automatically or manually relative to the outer casing assembly 110 between a locked position and an unlocked position. During the movement of the back panel assembly 120 from the unlocked position to the locked position, the movable locking hook 130 at least partially extends out of the support surface 121, achieving a fixed constraint on the mobile terminal 200 on the support surface 121; that is, the movable locking hook 130 and the fixed locking hook 122 jointly clamp and fix the mobile terminal 200. During the movement of the back panel assembly 120 from the locked position to the unlocked position, the movable locking hook 130 at least partially retracts below the support surface 121, and the clamping of the mobile terminal 200 fails, allowing it to be easily removed from the support surface 121.

[0071] Preferably, in this embodiment, the backplate assembly 120 is hinged to the outer casing assembly 110 via a horizontally extending pivot 140, meaning the backplate assembly 120 can rotate in a vertical plane. Furthermore, the angle between the supporting surface 121 and the horizontal plane when the backplate assembly 120 is in the locked position is larger than the angle between the supporting surface 121 and the horizontal plane when the backplate assembly 120 is in the unlocked position.

[0072] In other words, as the backplate assembly 120 rotates from the locked position to the unlocked position, the angle between the supporting surface 121 and the horizontal plane gradually increases. Conversely, as the backplate assembly 120 rotates from the unlocked position to the locked position, the angle between the supporting surface 121 and the horizontal plane gradually decreases.

[0073] Please refer to the following: Figure 3 and Figure 4 , Figure 3 The diagram shows the connection structure between the mobile terminal fixing device 100 and the mobile terminal 200 when the back panel assembly 120 is in the locked position. Figure 4 As shown Figure 3 A cross-sectional diagram.

[0074] In this embodiment, the fixed locking hook 122 is fixedly mounted on the back plate assembly 120 and protrudes from the supporting surface 121. The movable locking hook 130 and the fixed locking hook 122 are positioned opposite each other and spaced apart in the rotation plane of the back plate assembly 120, that is, the movable locking hook 130 and the fixed locking hook 122 are positioned opposite each other and spaced apart in the vertical plane. When the back plate assembly 120 moves to the locking position, the movable locking hook 130 is positioned above the fixed locking hook 122 in the vertical direction.

[0075] It is understandable that when the back panel assembly 120 is in the locked position, the movable locking hook 130 and the fixed locking hook 122 respectively hold the mobile terminal 200, and together achieve the clamping and fixing of the mobile terminal 200.

[0076] Please refer to the following: Figure 5 and Figure 6 , Figure 5 The diagram shows the connection structure between the mobile terminal fixing device 100 and the mobile terminal 200 when the back panel assembly 120 is in the unlocked position. Figure 6 As shown Figure 5 A cross-sectional diagram.

[0077] As the back panel assembly 120 rotates from the locked position to the unlocked position, it causes the mobile terminal 200 to flip. During this process, the movable locking hook 130 gradually moves relative to the support surface 121, and the gravity exerted by the mobile terminal 200 on the fixed locking hook 122 gradually increases.

[0078] When the back panel assembly 120 is rotated to the unlocked position, the movable locking hook 130 fully reaches below the supporting surface 121, releasing its constraint on the mobile terminal 200, that is, releasing the locking of the mobile terminal 200. At this time, due to the locking and supporting effect of the fixed locking hook 122, the mobile terminal 200 remains on the supporting surface 121.

[0079] Please refer to the following: Figure 7 and Figure 8 , Figure 7 The diagram shown is a structural schematic of removing the mobile terminal 200 from the mobile terminal fixing device 100. Figure 8 As shown Figure 7 A cross-sectional diagram.

[0080] When the back panel assembly 120 is in the unlocked position, the mobile terminal 200 is only tilted against the support surface 121. Applying a force to the mobile terminal 200 at this time can easily detach it from the back panel assembly 120. For example, a force can be applied to make it rotate around the fixed hook 122 as the center of rotation, and continue to rotate at a certain angle in a direction away from the support surface 121 to complete the disassembly.

[0081] If it is necessary to install the mobile terminal 200, the mobile terminal 200 can be placed on the fixed locking hook 122 and tilted against the supporting surface 121. Then, the back panel assembly 120 is rotated to the locking position. During the rotation, the movable locking hook 130 gradually extends out of the supporting surface 121 and holds the mobile terminal 200, thus working together with the fixed locking hook 122 to hold and fix the mobile terminal 200.

[0082] As can be seen, the mobile terminal fixing device 100 provided in this embodiment automatically completes the constraint or release of the mobile terminal 200 during the rotation of the back plate assembly 120. That is, together with the fixing hook 122, it realizes the clamping and fixing or releasing of the mobile terminal 200, making the disassembly and assembly of the mobile terminal 200 convenient, quick and easy, saving time and effort, and making it convenient for users to use.

[0083] Please refer to the following: Figure 9, Figure 9 The diagram shown is a structural schematic of the movable locking hook 130.

[0084] In this embodiment, the movable locking hook 130 is movably mounted on the back plate assembly 120. Specifically, the movable locking hook 130 has a holding part 131, a hinge part 132, and a sliding part 133. A clearance hole is provided on the supporting surface 121. The holding part 131 is used to extend out of the clearance hole to restrain the mobile terminal 200. The hinge part 132 is hinged to the back plate assembly 120, and the sliding part 133 is slidably engaged with the outer shell assembly 110.

[0085] During the process of the back plate assembly 120 rotating from the locked position to the unlocked position, the hinge portion 132 drives the movable locking hook 130 to move synchronously. During this process, the sliding portion 133 of the movable locking hook 130 slides on the outer shell assembly 110. During the sliding process, the sliding portion 133 is acted upon by the outer shell assembly 110, causing the movable locking hook 130 to rotate in the first direction until the holding portion 131 reaches below the supporting surface 121, that is, retracts into the clearance hole.

[0086] Specifically, the hinge portion 132 is provided with a mounting shaft hole, and the back plate assembly 120 is provided with a hinge shaft 128 passing through the mounting shaft hole. The movable locking hook 130 can rotate around the hinge shaft 128. In this embodiment, the hinge shaft 128 is parallel to the rotating shaft 140, that is, the plane in which the movable locking hook 130 rotates relative to the back plate assembly 120 is the same vertical plane as the plane in which the back plate assembly 120 rotates relative to the outer shell assembly 110.

[0087] Please refer to the following: Figure 10 and Figure 11 , Figure 10 The diagram shown is a partial structural schematic of the backplate assembly 120. Figure 11 for Figure 10 An enlarged schematic diagram of region A in the middle.

[0088] Furthermore, within the rotation plane of the backplate assembly 120, the hinge portion 132 and the sliding portion 133 are arranged at intervals. The outer shell assembly 110 has a guide groove 111, which extends within the rotation plane of the backplate assembly 120, i.e., in a vertical plane. The sliding portion 133 slides in conjunction with the guide groove 111, and the extending direction of the guide groove 111 forms an angle with the trajectory of the hinge portion 132 as it moves with the backplate assembly 120. In another embodiment, the guide groove 111 may be provided on the backplate assembly 120, and the sliding portion 133 may be provided on the outer shell assembly 110.

[0089] Specifically, the housing assembly 110 has two mounting portions 114 that are opposite to each other and spaced apart. A space for accommodating the movable locking hook 130 is formed between the two mounting portions 114. Each of the two mounting portions 114 is provided with a guide groove 111. Each of the opposite sides of the sliding portion 133 is provided with a mating protrusion. The two mating protrusions extend into the two guide grooves 111 respectively and slide in cooperation with the two guide grooves 111 respectively.

[0090] Please refer to the following: Figure 12 and Figure 13 , Figure 12 The image shown is a cross-sectional view of the mobile terminal fixing device 100 when the back panel assembly 120 is in the locked position. Figure 13 The image shown is another cross-sectional view of the mobile terminal fixing device 100 when the back panel assembly 120 is in the locked position.

[0091] When the back panel assembly 120 is in the locked position, the retaining part 131 of the movable locking hook 130 extends out of the supporting surface 121 through the clearance hole and faces the fixed locking hook 122, with the cooperating protrusion positioned at the end of the guide groove 111 away from the supporting surface 121. In this state, if a mobile terminal 200 is installed on the supporting surface 121, the mobile terminal 200 is clamped and fixed by the retaining part 131 and the fixed locking hook 122.

[0092] Please refer to the following: Figure 14 and Figure 15 , Figure 14 The image shown is a cross-sectional view of the mobile terminal fixing device 100 with the back panel assembly 120 in a state between the locked and unlocked positions. Figure 15 The diagram shows another cross-sectional view of the mobile terminal fixing device 100 with the back panel assembly 120 in a locked position and an unlocked position.

[0093] During the rotation of the back plate assembly 120 from the locked position to the unlocked position, the back plate assembly 120 drives the movable locking hook 130 to move synchronously through the hinge part 132. During this process, the end of the guide groove 111 of the mating protrusion provided in the sliding part 133 slides near the supporting surface 121.

[0094] Because the extension direction of the guide groove 111 forms an angle with the trajectory of the hinge portion 132 moving with the back plate assembly 120, during the sliding of the mating protrusion along the guide groove 111, it is pushed by the groove wall of the guide groove 111. The movement trajectories of the sliding portion 133 and the hinge portion 132 are inconsistent, causing the movable locking hook 130 to rotate around the hinge axis 128 in the first direction. During the rotation of the movable locking hook 130, the holding portion 131 is driven to gradually move below the supporting surface 121 along the relief hole.

[0095] Please refer to the following: Figure 16 and Figure 17 , Figure 16 The image shown is a cross-sectional view of the mobile terminal fixing device 100 when the back panel assembly 120 is in the unlocked position. Figure 17 The image shown is another cross-sectional view of the mobile terminal fixing device 100 when the back panel assembly 120 is in the unlocked position.

[0096] When the back panel assembly 120 rotates from the locked position to the unlocked position, the retaining part 131 of the movable locking hook 130 retracts below the supporting surface 121, and moves in conjunction with the protrusion to the end of the guide groove 111 near the supporting surface 121. In this state, if a mobile terminal 200 is installed on the supporting surface 121, the constraint of the retaining part 131 on the mobile terminal 200 is lost, that is, the mobile terminal 200 is no longer clamped and fixed by the retaining part 131 and the fixed locking hook 122.

[0097] To ensure that the mating protrusion can slide smoothly along the guide groove 111, the width of the guide groove 111 needs to be greater than the diameter of the mating protrusion. That is, there is a gap between the mating protrusion and the groove wall of the guide groove 111. This gap can easily cause the mating protrusion to get stuck during the sliding process along the guide groove 111, resulting in the back plate assembly 120 not switching smoothly between the locked and unlocked positions.

[0098] To address this issue, in this embodiment, the backplate assembly 120 is further provided with a first elastic element 123. The first elastic element 123 acts on the movable locking hook 130. Under the action of the first elastic element 123, the movable locking hook 130 tends to rotate in a second direction, which is opposite to the first direction.

[0099] Preferably, the first elastic element 123 is a torsion spring, sleeved on the hinge shaft 128, with one end abutting against the movable locking hook 130 and the other end abutting against the back plate assembly 120. Under the action of the first elastic element 123, the movable locking hook 130 tends to rotate in the second direction, so that the mating protrusion always maintains contact with one side wall of the guide groove 111, realizing the pre-tightening of the mating protrusion in the guide groove 111, avoiding jamming of the mating protrusion during sliding along the guide groove 111, thereby ensuring that the back plate assembly 120 can rotate smoothly. In this embodiment, under the action of the first elastic element 123, the mating protrusion always maintains contact with the upper side wall of the guide groove 111.

[0100] Please refer to the following: Figure 18 , Figure 18 The diagram shown is an exploded view of the housing assembly 110.

[0101] The housing assembly 110 is provided with a locking module 112 and a damping module 113. The locking module 112 is used to lock the back plate assembly 120 when it moves to the locked position, so as to keep the back plate assembly 120 in the locked position. The locking module 112 is also used to release the locking of the back plate assembly 120 under force. The damping module 113 is connected to the back plate assembly 120 and is used to drive the back plate assembly 120 to rotate from the locked position to the unlocked position after the locking module 112 releases the locking of the back plate assembly 120.

[0102] Please refer to the following: Figure 19 and Figure 20 , Figure 19 The image shown is another cross-sectional view of the mobile terminal fixing device 100 when the back panel assembly 120 is in the locked position. Figure 20 As shown Figure 19 Enlarged schematic diagram of region B in the middle.

[0103] In this embodiment, the locking module 112 is a press-to-unlock labyrinth lock. A backplate hook 1291 protrudes from the side of the backplate assembly 120 opposite to the supporting surface 121. During the rotation of the backplate assembly 120 from the unlocked position to the locked position, the backplate hook 1291 is inserted into the labyrinth lock. When the backplate assembly 120 reaches the locked position, the labyrinth lock locks the backplate hook 1291, thereby locking the backplate assembly 120.

[0104] The maze lock is provided with a locking mechanism 1121 and a moving hook 1122 that are opposite to each other and spaced apart. When the back plate assembly 120 reaches the locking position, the back plate hook 1291 is inserted between the locking mechanism 1121 and the moving hook 1122. The moving hook 1122 and the back plate hook 1291 are hooked together. The side of the back plate hook 1291 that is away from the moving hook 1122 is stopped and limited by the locking mechanism 1121.

[0105] Please refer to the following: Figure 21 and Figure 22 , Figure 21 The image shown is another cross-sectional view of the mobile terminal fixing device 100 when the back panel assembly 120 is in the unlocked position. Figure 22 As shown Figure 21 A magnified view of region C in the middle.

[0106] When it is necessary to release the lock on the back panel assembly 120, press the mobile terminal 200 or the back panel assembly 120 towards the housing assembly 110 to unlock the maze lock and release the back panel lock hook 1291, thereby releasing the lock on the back panel assembly 120.

[0107] After the maze lock is unlocked, the damping module 113 drives the backplate assembly 120 to rotate from the locked position to the unlocked position. During this process, the backplate assembly 120 drives the backplate hook 1291 to pull the locking mechanism 1121 and the moving hook 1122 out of the maze lock opening together. The maze lock opening is provided with a guide slope 1123 to guide the moving hook 1122 to disengage from the backplate hook 1291. As the moving hook 1122 extends out of the maze lock opening, it slides along the guide slope 1123 until it disengages from the backplate hook 1291, allowing the backplate hook 1291 to continue moving with the backplate assembly 120.

[0108] In other embodiments, the locking module 112 may have other structures and use other principles to lock and unlock the back panel assembly 120, which is not specifically limited in this application.

[0109] Please refer to the following: Figure 23 , Figure 24 and Figure 25 , Figure 23 The diagram shown is an exploded view of the damping module 113. Figure 24 The diagram shown is a cross-sectional view of the damping module 113. Figure 25 The diagram shown is another cross-sectional view of the damping module 113.

[0110] In this embodiment, the damping module 113 includes a base 1131, a slider 1132, and a second elastic element 1133. The base 1131 is disposed on the housing assembly 110, the slider 1132 is slidably engaged with the base 1131, and the slider 1132 is connected to the back plate assembly 120. The second elastic element 1133 is disposed between the slider 1132 and the base 1131, and is used to push the slider 1132 to slide relative to the base 1131 after the locking module 112 releases the lock on the back plate assembly 120, so as to drive the back plate assembly 120 to the unlocked position.

[0111] Preferably, a limiting post 1139 is provided on the base 1131, and the second elastic element 1133 is a compression spring sleeved on the limiting post 1139. It can be understood that during the rotation of the back plate assembly 120 from the unlocked state to the locked state, the back plate assembly 120 drives the slider 1132 to slide towards the outer shell assembly 110, and the second elastic element 1133 is gradually compressed, accumulating elastic potential energy. When the locking module 112 releases the lock on the back plate assembly 120, the second elastic element 1133 releases its elastic potential energy, pushing the slider 1132 to slide towards the back plate assembly 120, thereby causing the back plate assembly 120 to rotate towards the unlocked position.

[0112] To prevent the back panel assembly 120 from rotating too fast due to the rapid sliding of the slider 1132, which could cause the mobile terminal 200 to fly out when the back panel assembly 120 reaches the unlock position, in this embodiment, a reduction gear 1135 is provided on the base 1131, and a fixed gear 1136 is provided on the slider 1132. The fixed gear 1136 meshes with the reduction gear 1135. During the sliding of the slider 1132 relative to the base 1131, the reduction gear 1135 rotates relative to the fixed gear 1136.

[0113] Understandably, the reduction gear 1135 is preset to rotate only at a constant, slow speed, thereby limiting the sliding speed of the slider 1132 on the base 1131, so that the back plate assembly 120 can rotate smoothly to the unlock position at a slow speed, ensuring that the mobile terminal 200 installed on the support surface 121 can maintain a stable state.

[0114] In another embodiment, the reduction gear 1135 may be disposed on the slider 1132, and the fixed gear 1136 may be disposed on the base 1131.

[0115] In this embodiment, the slider 1132 also has a limiting part 1137, and the base 1131 has a stop part 1138. The stop part 1138 is used to abut against the limiting part 1137 so that the back plate assembly 120 is held in the unlocked position under the action of the second elastic member 1133.

[0116] In practical applications, after the locking module 112 releases the lock on the back plate assembly 120, the slider 1132, under the action of the second elastic element 1133, drives the limiting part 1137 to gradually slide closer to the stop part 1138. When the limiting part 1137 moves to abut against the stop part 1138, the slider 1132 stops sliding, and the back plate assembly 120 reaches the unlocked position.

[0117] Please refer to the following: Figure 26 and Figure 27 , Figure 26 The diagram shown is a cross-sectional view of the connection structure between the backplate assembly 120 and the damping module 113 when the backplate assembly 120 is in the locked position. Figure 27 The diagram shown is a cross-sectional view of the connection structure between the backplate assembly 120 and the damping module 113 when the backplate assembly 120 is in the unlocked position.

[0118] In order to ensure that the back plate assembly 120 can rotate smoothly under the drive of the damping module 113, in this embodiment, the back plate assembly 120 has a strip hole 124 extending in the rotation plane of the back plate assembly 120, and the slider 1132 is provided with a sliding boss 1134 that slides with the strip hole 124.

[0119] It is understandable that as the slider 1132 slides toward the back plate assembly 120, the sliding boss 1134 applies a pushing force to the wall of the slot 124, causing the back plate assembly 120 to rotate around the pivot 140. During this process, the sliding boss 1134 slides relative to the slot 124, ensuring that the elastic force of the second elastic element 1133 is always tangential to the rotation direction of the back plate assembly 120.

[0120] In another embodiment, the strip hole 124 may be disposed on the slider 1132, and the sliding boss 1134 may be disposed on the back plate assembly 120.

[0121] Please refer to the following: Figure 28 , Figure 28 The diagram shown is an exploded view of the backplate assembly 120.

[0122] In this embodiment, the back plate assembly 120 is also provided with a plurality of magnetic elements 125, which are located at a plurality of different parts of the back plate assembly 120, for magnetically attracting the mobile terminal 200 at a plurality of different parts of the back plate assembly 120, so as to guide the mobile terminal 200 to remain in a fixed position on the support surface 121.

[0123] In fact, the multiple magnetic components 125 correspond to multiple different parts of the support surface 121. After the mobile terminal 200 is installed on the support surface 121, it can always maintain a stable posture under the magnetic attraction of the multiple magnetic components 125, ensuring that the mobile terminal 200 can rotate synchronously with the back panel assembly 120.

[0124] Furthermore, the back panel assembly 120 is also equipped with a charging module 126 and a buffer 127. The charging module 126 is used to charge the mobile terminal 200. When the user presses the mobile terminal 200 or the back panel assembly 120 to rotate the back panel assembly 120 from the unlocked position to the locked position, the buffer 127 abuts against the outer shell assembly 110 and absorbs the kinetic energy of the back panel assembly 120, ensuring that the rotation of the back panel assembly 120 is smooth.

[0125] In summary, the mobile terminal fixing device 100 provided in this embodiment enables the mobile terminal 200 to be installed, disassembled, and used conveniently, resulting in a better user experience.

[0126] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
