[0026] The pull-out type electronic device protective shell has a simple structure and an ingenious design. If the electronic device needs to be installed in the electronic device protective shell, it is only necessary to pull and move the first substrate and the second substrate in two opposite directions respectively, and the distance adjustment component is automatically unlocked. In the process of the first substrate and the second substrate moving away from each other, the distance adjustment component is driven to automatically increase the distance between the first edge and the second edge. When the first substrate and the second substrate are moved into place, the distance adjustment component locks and fixes the first substrate and the second substrate, thereby ensuring that the distance between the first edge and the second edge remains unchanged. The user can directly put the electronic device into the storage cavity, and then pull and move the first substrate and the second substrate towards each other at the same time, and the distance adjustment component is automatically unlocked. In the process of the first substrate and the second substrate moving close to each other, the distance adjustment component is driven to automatically reduce the distance between the first edge and the second edge, until the first edge and the second edge are respectively fitted with the top angles of the electronic device, and the distance adjustment component automatically locks and fixes the first substrate and the second substrate, thereby achieving the purpose of fixing the electronic device in the storage cavity on the electronic device protective shell; if the electronic device is to be taken out of the electronic device protective shell, it is only necessary to repeat the above operation, and the operation is simple, and the electronic device is easy to disassemble and assemble.

[0027] In one embodiment, a first connecting member 112 extending in the length direction of the electronic device is provided at one end of the first substrate 11 facing the second substrate 12, and a first sliding groove 122 corresponding to the first connecting member 112 and slidably connected thereto is provided on the second substrate 12, which is convenient for pulling and drawing, and the first sliding groove 122 also has a guiding and directional function, so that the second substrate 12 can move closer to or away from the first substrate 11 along a preset route. Furthermore, the first connecting member 112 extends from one end of the first substrate 11 toward the second substrate 12, and the first connecting member 112 is arranged in a flat long strip shape; the shape of the first slide groove 122 matches the shape of the first connecting member 112; optionally, the first connecting member 112 can also be arranged on the second substrate 12, and the first slide groove 122 is arranged on the first substrate 11, and the above simple position replacements all fall within the protection scope of the utility model; a first positioning groove 113 and a second positioning groove 114 are sequentially provided on one side surface of the first connecting member 112 along its length direction; an elastic locking member that cooperates with the first positioning groove 113 or the second positioning groove 114 is provided between the first substrate 11 and the second substrate 12; the first connecting member 112 and the elastic locking member constitute a distance adjustment component with a simple structure. Furthermore, a guide portion (not shown in the figure) protruding outward is provided on one side surface of the first connecting member 112 facing the first slide groove 122; the guide portion (not shown in the figure) extends along the length direction of the first connecting member 112; the bottom of the first slide groove 122 is provided with a guide slide groove 1221 that is slidably connected to the guide portion (not shown in the figure); the positioning is accurate and the guiding property is good; optionally, the guide portion (not shown in the figure) can also be arranged in the first slide groove 122, and the guide slide groove 1221 is arranged on the first connecting member 112; optionally, the distance adjustment component can also adopt the distance adjustment structure commonly used in the prior art.

[0028] Furthermore, when the elastic locking piece is engaged with the first positioning groove 113, the first substrate 11 and the second substrate 12 are in an open state, and the space of the storage cavity 13 is increased; when the elastic locking piece is engaged with the second positioning groove 114, the first substrate 11 and the second substrate 12 are in a closed connection state, and the space of the storage cavity 13 is adapted to the outer contour of the electronic device; the connection is stable, and the space size of the storage cavity 13 is adjustable, which is convenient for installing the electronic device in the electronic device protective shell or removing the electronic device from the electronic device protective shell.

[0029] Furthermore, the elastic locking member includes a mounting groove 123 disposed on the second substrate 12 and connected to the first slide groove 122, a buckle 124 movably disposed in the mounting groove 123, and an elastic member 125 providing elastic force to the buckle 124 and the second substrate 12; in one embodiment, the elastic locking member can be disposed on a side surface of the second substrate 12 facing the electronic device, or on a side surface of the second substrate 12 facing away from the electronic device.

In the natural state, the elastic member 125 is in a free state, and the front end of the buckle 124 is extended into the first slide groove 122. When the first positioning groove 113 and the second positioning groove 114 on the first connecting member 112 are misaligned with the mounting groove 123, the first connecting member 112 applies pressure to the buckle 124, so that the buckle 124 moves in the mounting groove 123 in the direction away from the first slide groove 122 until the buckle 124 moves out of the first slide groove 122. Outside the groove 122, the elastic member 125 is in a compressed state under force. At this time, the distance adjustment component is unlocked, and the first substrate 11 and the second substrate 12 can be pulled and moved relative to each other; when the first positioning groove 113 or the second positioning groove 114 is connected to the installation groove 123, the first connecting member 112 does not exert force on the buckle 124, and the elastic member 125 automatically resets and drives the buckle 124 to extend into the corresponding first positioning groove 113 or the second positioning groove 114. At this time, the distance adjustment component is in a locked state, and the first substrate 11 and the second substrate 12 are fixedly connected, which is flexible to use.

[0031] Furthermore, the moving direction of the locking member 124 is perpendicular to the moving direction of the first connecting member 112 , so that the first substrate 11 and the second substrate 12 can be locked and fixed within the shortest stroke.

[0032] Optionally, in order to make the relative pulling of the first substrate 11 and the second substrate 12 more stable, the first substrate 11 is provided with a second connecting member 115 extending toward the second substrate 12 and a second slide groove 116 extending from the outer edge of the first substrate 11 in a direction away from the second substrate 12 on both sides of the end of the first substrate 11; the second connecting member 115 and the second slide groove 116 are both arranged in a long strip shape. The second connecting member 115 has the same shape as the first connecting member 112 and is arranged parallel to each other. Furthermore, the second substrate 12 is provided with a third slide groove 128 corresponding to the second connecting member 115 and slidingly connected therewith, and a third connecting member 129 corresponding to the second slide groove 116 and slidingly connected therewith on both sides; the third slide groove 128 and the second slide groove 116 are both parallel to the first slide groove 122 and slide smoothly.

[0033] In order to further enhance the stability of the movement of the first substrate 11 and the second substrate 12, a guide groove 1281 is provided in the second slide groove 116 or the third slide groove 128 along its length direction, and a guide block (not shown in the figure) is provided on the second connecting member 115 or the third connecting member 129 and is slidably connected with the guide groove 1281; a first engaging position A and a second engaging position B that are connected are provided in the guide groove 1281; when the guide block (not shown in the figure) moves to the first engaging position A, the elastic locking member is engaged with the first positioning groove 113; when the guide block (not shown in the figure) moves to the second engaging position B, the elastic locking member is engaged with the second positioning groove 114, and optionally, the second slide groove 116 and the third slide groove 128 can also be provided with guide grooves 1281, and the corresponding second connecting member 115 and the third connecting member 129 are provided with guide blocks (not shown in the figure); the connectivity is good, and the first substrate 11 will not be easily separated from the second substrate 12 completely.

[0034] Furthermore, a lens protection frame 1211 corresponding to the camera of the electronic device is provided on the second substrate 12; the distance adjustment component and the third slide groove 128 are located on the same side of the lens protection frame 1211; the third connecting member 129 is located on the side of the lens protection frame 1211 facing the second substrate 12, and the structural layout is reasonable and the connection is stable.
