The housing 100 generally includes a center frame 110, and an opening 111 may be opened in the center frame 110. Of course, the opening 111 may be formed in other portions of the housing 100, and the specific opening position of the opening 111 is not limited in the embodiments of the present invention.

In the embodiment of the present invention, the driving mechanism 300 includes a driving motor 310 and a rack 321, the rack 321 is disposed inside the housing 100, and an extending direction of the rack 321 coincides with a moving direction of the driven device 200. The driving motor 310 is connected to the driven device 200. The driving motor 310 is in transmission connection with the rack 321, so that the driving motor 310 and the rack 321 can move relatively in the extending direction of the rack 321.

Under normal circumstances, when the driven device 200 extends out of the housing 100, power needs to be supplied, and based on this, the electronic device disclosed in the embodiment of the present invention may further include a flexible electrical connector 500, one end of the flexible electrical connector 500 is electrically connected to the driven device 200, and the other end of the flexible electrical connector 500 is electrically connected to the main board 400 of the electronic device, so that the main board 400 supplies power to the driven device 200. The flexible electrical connector 500 has good deformability, and therefore can better accommodate the retention of the power supply during movement of the driven device 200. In particular, the flexible electrical connector 500 may be an electrical connector with good deformability, such as a flexible circuit board, a flexible cable, or the like.

In a preferred embodiment, the driving motor 310 is electrically connected to the flexible electrical connector 500, in which case the flexible electrical connector 500 can provide power to both the driven device 200 and the driving motor 310.

In the embodiment of the present invention, the driven device 200 may include a device holder 210 and a device main body 220, the device main body 220 is a main body portion of the driven device 200 that performs its function, the device holder 210 provides a mounting position for the device main body 220, and the device main body 220 is disposed on the device holder 210. Generally, the device body 220 can be fixed to the device holder 210 by clamping, bonding, or fastening (e.g., threaded) connection. Device body 220 is generally disposed within device holder 210 so as to be shielded by device holder 210.

The device holder 210 not only provides a mounting position for the device main body 220, as described above, the driving motor 310 is connected to the driven device 200, and the driving motor 310 may be disposed on the device holder 210 on the premise that the driven device 200 includes the device holder 210. Specifically, the driving motor 310 may be fixed to the device holder 210, thereby achieving connection with the driven device 200.

The driving motor 310 may be disposed on the device holder 210 in various manners, and referring to fig. 3 and 4 again, in a preferred embodiment, the device holder 210 may include a holder main body 211 and a fixing holder 212, and the fixing holder 212 is fixedly connected to the holder main body 211.

This way, the compactness of assembling the device holder 210 with the driving motor 310 can be improved. For example, the driving motor 310 may have a cylindrical structure, and the inner wall of the installation space may have a circular arc surface, so as to better implement the installation of the driving motor 310 in the installation space. In a preferred embodiment, the fixing bracket 212 may be a one-piece structure with the bracket body 211, thereby facilitating manufacturing and assembling.

As described above, the driving motor 310 may be electrically connected to the flexible electrical connector 500, and there are various ways to electrically connect the driving motor 310 to the flexible electrical connector 500, please refer to fig. 3, 4 and 5, the bottom wall of the trough-shaped structure 212a may be provided with the first connection hole 212a1, the driving motor 310 may include the power plug 311, the power plug 311 is plugged into the first connection hole 212a1, and the power plug 311 passes through the first connection hole 212a1 and is electrically connected to the flexible electrical connector 500. In this case, the engagement between the power plug 311 and the first connection hole 212a1 not only enables better installation of the driving motor 310 in the installation space, but also enables power supply connection between the driving motor 310 and the flexible electrical connector 500.

In a more preferable scheme, the fixing bracket 212 may further include a supporting base 212b, the groove-shaped structure portion 212a may be fixed on the supporting base 212b, a gap may be formed between the supporting base 212b and the groove-shaped structure portion 212a for the flexible electrical connector 500 to pass through, the flexible electrical connector 500 is provided with a second connecting hole 510 located in the gap, the power plug 311 may pass through the first connecting hole 212a1 and pass through the second connecting hole 510, and the power plug 311 is connected to the second connecting hole 510 in a welding manner, so as to achieve electrical connection between the power plug 311 and the flexible electrical connector 500.

Of course, the gap formed between the support base 212b and the groove-shaped structure portion 212a is less likely to be interfered by components in the external environment, and the electrical connection position between the power plug 311 and the flexible electrical connector 500 is located in the gap, so that the stability of the electrical connection can be better ensured under the protection of the support base 212b and the groove-shaped structure portion 212 a.

In the electronic device disclosed in the embodiment of the present invention, the driving mechanism 300 includes the rack assembly 320, the rack assembly 320 includes the above-mentioned rack 321 and the rack bracket 322, the rack 321 may be disposed on the rack bracket 322, the rack bracket 322 is fixed in the casing 100, specifically, the rack bracket 322 may be fixed in the casing 100 by a screw 325, and specifically, the rack bracket 322 may be fixed on the main board 400 in the casing 100 by a screw 325. The rack 321 extends in the moving direction of the driven device 200. The power output shaft of the driving motor 310 is provided with a gear 340, and the gear 340 is engaged with the rack 321, so that power transmission between the driving motor 310 and the rack 321 is realized, as shown in fig. 3.

In order to better control the movement of the driven device 200, the driving mechanism 300 may further include a speed reducer 330, and the driving motor 310 may be in transmission connection with a gear 340 through the speed reducer 330, as shown in fig. 3. In a general case, the decelerator 330 may be a gear decelerator.

Referring to fig. 6, in a preferable scheme, the electronic device disclosed in the embodiment of the present invention may further include a main board 400, the main board 400 may be provided with an avoidance gap 410, the rack bracket 322 may be fixed at an edge of the avoidance gap 410, the rack 321 is located at one side of the driven device 200, and the driven device 200 is located in the avoidance gap 410 when the driven device 200 is located in the housing 100. In this case, the main board 400 sacrifices a part of its structure to form the avoiding notch 410, and further accommodates the driven device 200, so that the stacking height between the driven device 200 and the main board 400 can be reduced, which is beneficial to design of electronic equipment in a thinner direction.

Meanwhile, the rack bracket 322 is fixed at the edge of the avoiding notch 410, and the rack 321 is positioned at one side of the driven device 200, so that the space occupation in the moving direction of the driven device 200 can be reduced. Meanwhile, the movement of the driven device 200 and the driving motor 310 is not affected by the rack 321, which is advantageous for simplifying the assembly.

In an embodiment of the present invention, the rack 321 may be fixed within the housing 100. Specifically, the rack 321 may be fixed on the rack holder 322, for example, the rack 321 may be fixedly connected to the rack holder 322 by welding, clamping, or connecting (threaded connecting) means. In this case, the rack 321 remains stationary during the movement of the driven device 200.

Of course, the rack 321 may be movably disposed in the housing 100, as long as the whole formed by the driving motor 310 and the driven device 200 is ensured to be capable of moving relative to the rack 321, so as to ensure that the driven device 200 enters and exits the housing 100 through the opening 111.

In a specific moving process, the driving motor 310 and the driven device 200 occupy a larger space in the housing 100 due to a longer moving stroke, and thus, it is difficult to integrate more electronic components in the housing 100. Based on this, in a more preferable scheme, the rack assembly 320 may further include an auxiliary driving mechanism, and the rack 321 is slidably disposed on the rack bracket 322, so that the rack 321 can move relative to the rack bracket 322, and finally, the movement of the rack 321 in the housing 100 is realized.

In the embodiment of the present invention, the end of the rack bracket 322 connected to the driven device 200 is a first end, and the rack bracket 322 includes a first position-limiting portion 3221 disposed at the first end. The rack 321 may be provided with a mounting groove 3211, and the mounting groove 3211 extends along a length direction of the rack 321. The both ends of mounting groove 3211 are open end and blind end respectively, and the open end communicates with the inslot space of mounting groove 3211. The open end faces the retraction direction of the driven device 200. The auxiliary driving mechanism is disposed between the closed end and the first position-limiting portion 3221, the auxiliary driving mechanism drives the rack 321 to move toward the direction in which the driven device 200 extends, and the first position-limiting portion 3221 is located outside or inside the open end along with the sliding of the rack 321. In this case, the auxiliary driving mechanism applies a force to the closed end based on the first position-limiting portion 3221, so as to drive the rack 321 to move, and the movement of the rack 321 drives the driving motor 310 and the driven device 200 to extend together.

When a user needs to extend the driven device 200 out of the housing 100, the driving mechanism 300 is turned on, the driving motor 310 is engaged with the rack 321, the driving motor 310 carries the driven device 200 to move towards the direction in which the driven device 200 extends, since the rack 321 is slidably disposed on the rack support 322, and the rack support 322 is fixed in the housing 100, and the auxiliary driving mechanism is disposed between the closed end of the mounting groove 3211 and the first limit portion 3221, the auxiliary driving mechanism has a tendency to drive the rack 321 to move towards the direction in which the driven device 200 extends, so as to assist in driving the driven device 200 to further move. The first position-limiting portion 3221 can be located outside or inside the open end along with the sliding of the rack 321. In this case, the auxiliary driving mechanism can further apply driving to the rack 321 through the closed end based on the first position-limiting portion 3221, so that the rack 321 drives the driving motor 310 and the driven device 200 to move together in the extending direction.

In the case where the electronic device includes an auxiliary drive mechanism, during retraction of the driven device 200, the driving motor 310 is rotated in reverse, thereby moving in a direction of being retracted by the driving device 200 with respect to the rack gear 321, since the rack 321 is slidably disposed on the rack bracket 322, and the rack bracket 322 is fixed in the housing 100, in order to enable the driving motor 310 to drive the driven device 200 to retract through the cooperation with the rack 321, the rack support 322 may include a second position-limiting portion 3222, the second position-limiting portion 3222 is disposed at a second end of the rack support 322 facing the opening 111, the second position-limiting portion 3222 is in position-limiting engagement with a corresponding end portion of the rack 321, in the retracting process, since the second position-limiting portion 3222 is in position-limiting fit with the corresponding end portion of the rack 321, therefore, the rack 321 will not slide relatively, and the driving motor 310 will finally drive the driven device 200 to retract into the housing 100 through the transmission cooperation with the rack 321.

In an embodiment of the present invention, the auxiliary driving mechanism may be an elastic expansion part 323, the elastic expansion part 323 expands and contracts along a moving direction of the driven device 200, and two ends of the elastic expansion part 323 are positioned between the closed end and the first position-limiting part 3221. During the process that the driving mechanism 300 drives the driven device 200 to extend out of the housing 100, the rack 321 slides relative to the rack support 322, and further the elastic expansion piece 323 is compressed through the closed end, because the rack 321 has a certain speed and the elastic expansion piece 323 has elasticity, during the sliding process of the rack 321, the extending speed of the driving motor 310 and the driven device 200 does not reach the sliding speed of the rack 321, and the elastic expansion piece 323 can be gradually compressed. When the driving motor 310 is engaged with the end of the rack 321, the elastic expansion element 323 is compressed to the shortest distance, in this case, the first position-limiting portion 3221 has moved relatively from the open end to the mounting groove 3211, and is located in the open end.

Meanwhile, because one end of the elastic expansion piece 323 is positioned at the closed end of the mounting groove 3211, and the rack 321 is still engaged with the driving motor 310, under the action of the elastic restoring force of the elastic expansion piece 323, the elastic expansion piece 323 pushes the closed end of the mounting groove 3211 based on the first position-limiting portion 3221, thereby achieving the purpose of pushing the rack 321 to drive the driving motor 310 and the driven device 200 to continue to extend.

After the driven device 200 is completely operated, the driving mechanism 300 is turned on, the driving motor 310 drives the driven device 200 to move in the retracting direction through the engagement of the rack 321, and the rack 321 is in limit fit with the second limit portion 3222, so that the rack 321 does not slide relatively in the moving process in the retracting direction, and is used as an engagement basis for the driving motor 310 to move back, and finally, the driven device 200 retracts into the housing 100. Of course, the length of the elastic expansion element 323 can be designed reasonably by those skilled in the art, so as to ensure that the elastic expansion element 323 can be in a natural state when the driven device 200 is located in the casing 100, without applying an elastic force to the driven device 200, thereby avoiding that the driven device 200 is always subjected to an elastic force when located in the casing 100.

The elastic expansion element 323 in the embodiment of the present invention may be various, such as a silicone elastic element, a rubber element, and a coil spring, and the embodiment of the present invention does not limit the specific type of the elastic expansion element 323. During operation, the elastic expansion element 323 can be deformed telescopically.

In the electronic device disclosed in the above preferred embodiment, when the driving mechanism 300 for driving the driven device 200 to extend out works, the driving motor 310 moves relative to the rack 321 by engaging with the rack 321, the rack 321 also slides relative to the rack bracket 322, the sliding of the rack 321 can compress the elastic expansion member 323 between the first position-limiting portion 3221 and the closed end of the mounting groove 3211, and the elastic expansion member 323 is compressed during the movement of the rack 321, so that after the rack 321 stops, the elastic potential energy of the elastic expansion member 323 compressing the accumulated elastic potential energy can be converted into the kinetic energy for continuously pushing the driven device 200, the driving motor 310 and the rack 321 to continue to move towards the extending direction, and the driving mechanism 300 can push the driven device 200 for a longer distance through the elastic expansion member 323 during the whole driving process, and under the premise of the same extending distance, the driving mechanism 300 of the electronic device disclosed in the present invention can occupy more in the expanding direction of the driven device 200 A small space.

In the embodiment of the present invention, the auxiliary driving mechanism is not limited to the elastic telescopic element 323, and the auxiliary driving mechanism may further include two magnetic elements with the same polarity, one of the two magnetic elements is disposed on the first position-limiting portion 3221, and the other magnetic element is disposed at the closed end.

On the premise that the auxiliary driving mechanism includes two magnetic members with the same polarity, in the process that the driving mechanism 300 drives the driven device 200 to extend out of the housing 100, the driving motor 310 is engaged with the rack 321, so that the rack 321 slides relative to the rack support 322, the sliding of the rack 321 can gradually decrease the distance between the two magnetic members, so that the repulsive force between the two magnetic members is gradually increased, after the rack 321 stops, one magnetic member can drive the other magnetic member, the rack 321, the driving motor 310 and the driven device 200 to continue to move in the extending direction of the driven device 200 by applying the repulsive force to the other magnetic member based on the first limiting portion 3221, so as to push the driven device 200 for a longer distance.

In the embodiment of the present invention, the first position-limiting portion 3221 may be a position-limiting piece, and the second position-limiting portion 3222 may also be a position-limiting piece. The embodiment of the invention does not limit the specific structures of the first position-limiting portion 3221 and the second position-limiting portion 3222.

As described above, the rack bracket 322 can support the rack gear 321 such that the rack gear 321 moves relative to the rack bracket 322.
