Specifically, the engaging support 600 is rotatably engaged with the device support 210, so that the whole driven device 200 can rotate relative to the engaging support 600.

In a specific embodiment, the driven device 200 may be a camera module, in which case the device holder 210 is a camera holder and the device main body 220 is a camera.

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 through the engaging holder 600, but also the driving motor 310 may be connected to the device holder 210 through the engaging holder 600 on the premise that the driven device 200 includes the device holder 210. Specifically, the driving motor 310 may be fixed to the engagement bracket 600, thereby being coupled to the engagement bracket 600.

This way, the compactness of assembling the engagement bracket 600 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.

As mentioned above, the driving motor 310 can 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. 6 again, the bottom wall of the trough-shaped structure portion 610 can be opened with the first connection hole 611, the driving motor 310 can include the power plug 311, the power plug 311 is plugged in the first connection hole 611, and the power plug 311 passes through the first connection hole 611 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 611 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 linking bracket 600 may further include a supporting base 620, the groove-shaped structure portion 610 may be fixed on the supporting base 620, a gap through which the flexible electrical connector 500 may pass may be formed between the supporting base 620 and the groove-shaped structure portion 610, 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 611 and pass through the second connecting hole 510, and the power plug 311 is connected to the second connecting hole 510 by welding, so as to achieve electrical connection between the power plug 311 and the flexible electrical connector 500. The above-described manner of soldering can ensure stability of electrical connection. The flexible electrical connector 500 extends through the gap formed by the support platform 620 and the channel 610. The assembly of the gap and the flexible electrical connector 500 not only can improve the compactness of the assembly, but also can play a role in protecting part of the flexible electrical connector 500.

Of course, the gap formed between the supporting platform 620 and the groove-shaped structure portion 610 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 supporting platform 620 and the groove-shaped structure portion 610.

Referring to fig. 3 to 8 again, in a specific embodiment, the driven device 200 may further include a rotating shaft 230, the engaging bracket 600 may be provided with a rotating shaft hole 630, and the rotating shaft 230 is matched with a shaft hole formed by the rotating shaft hole 630, so as to realize rotational matching. The adoption of the manner in which the rotating shaft 230 is fitted with the rotating shaft hole 630 can certainly further improve the assemblability.

In a preferable scheme, the hole wall of the rotating shaft hole 630 may be provided with a circumferentially extending clamping groove 631, the outer side wall of the rotating shaft 230 may be provided with a clamping ring 231, the clamping ring 231 and the clamping groove 631 are in limited fit in the axial direction of the rotating shaft 230, and the clamping ring 231 and the clamping groove 631 are in sliding fit in the circumferential direction of the rotating shaft 230. In a specific assembling process, the rotating shaft 230 is inserted into the rotating shaft hole 630, and the snap ring 231 can slide into the card slot 631 by slight deformation in the inserting process, so that the snap ring is matched with the card slot 631. The snap ring 231 and the snap groove 631 are engaged to prevent the driven device 200 from falling off.

Of course, there are various structures for preventing the rotation shaft 230 from falling off from the rotation shaft hole 630, for example, the rotation shaft 230 may be a stepped shaft, and the stepped surface of the rotation shaft 230 may be in limit fit with an end cover installed at the port of the rotation shaft hole 630, so as to prevent the rotation shaft 230 from falling off from the rotation shaft hole 630. The end cap may be detachably mounted at the port of the rotation shaft hole 630 by a screw coupling.

In a specific working process, the driven device 200 rotates to adjust the working direction, in a normal case, the driven device 200 does not need to rotate within a range of 360 degrees, and in many cases, the driven device 200 rotates excessively to influence the connection between the driven device and other components of the electronic device. For example, over-rotation of driven device 200 may cause flexible electrical connector 500 to be damaged by a large twisting force. Based on this, in a preferable scheme, the hole wall of the rotating shaft hole 630 may be provided with a limiting groove 632 extending along the circumferential direction thereof, the outer wall of the rotating shaft 230 may be provided with a limiting protrusion 232, and the limiting protrusion 232 and the limiting groove 632 are in limiting fit in the circumferential direction of the rotating shaft 230. Specifically, the limiting protrusion 232 can slide into the limiting groove 632 through slight deformation generated in the process of inserting the rotating shaft 230 into the rotating shaft hole 630. The cooperation between the limiting protrusion 232 and the limiting groove 632 can prevent the driven device 200 from rotating excessively and unlimitedly.

However, in order to achieve better rotation limitation, the height dimension of the limiting protrusion 232 can be designed to be larger, so as to enhance the effect of the limiting fit. In order to facilitate the installation of the limiting protrusion 232, in a preferred embodiment, the hole wall of the rotating shaft hole 630 may be provided with a guide groove 633 extending along the axis direction thereof, a port of one end of the guide groove 633 is located on the end surface of the engagement bracket 600 facing the driven device 200, the other end of the guide groove 633 is communicated with the limiting groove 632, and the guide groove 633 may be in guiding fit with the limiting protrusion 232. In a specific assembling process, an operator can align the limiting protrusion 232 with the guide groove 633, then forcibly push the rotating shaft 230 into the rotating shaft hole 630 until the limiting protrusion 232 enters a position where the guide groove 633 is communicated with the limiting groove 632, and then rotate the driven device 200 to realize installation.

In order to avoid that the rotation of the driven device 200 is too flexible to affect the adjustment of its angle. In a more preferable scheme, a damping mechanism may be disposed in a surface of the driven device 200 opposite to the engagement bracket 600, for example, the damping mechanism may be an elastic damping pad. In this case, the damping mechanism can perform a damping function during the rotation of the driven device 200 with respect to the engaging bracket 600.

In a preferable embodiment, one of the surfaces of the driven device 200 opposite to the engaging bracket 600 is provided with a damping protrusion 634, the other one is provided with a damping recess 211, at least two of the damping protrusions 634 and the damping recesses 211 are arranged at intervals along the rotation direction of the driven device 200, the damping protrusion 634 and the damping recess 211 are elastically clamped in the rotation direction of the driven device 200, so as to form an elastically clamped damping structure, and in the process of adjusting the angle of the driven device 200, a certain force needs to be applied to rotate the driven device 200. After the external force is removed, the driven device 200 can be better kept at the adjusted position due to the elastic clamping between the damping protrusion 634 and the damping recess 211.

Referring again to fig. 7 and 8, in one embodiment, the number of the damping protrusions 634 and the damping recesses 211 is multiple, and both may be disposed at equal intervals in the rotation direction of the driven device 200.

In the embodiment of the present invention, the rotating shaft 230 may be a hollow shaft, and the hollow shaft not only can make the weight of the driven device 200 smaller, and facilitate the rotation adjustment. Meanwhile, on the premise that the electronic device includes the above-mentioned flexible electrical connector 500, one end of the flexible electrical connector 500 may be electrically connected to the driven device 200, and the other end of the flexible electrical connector 500 may be inserted into the rotation shaft 230. The other end of the flexible electrical connector 500 passes through the engaging bracket 600 along with the rotating shaft 230 and is electrically connected with the main board 400 of the electronic device. In this case, during the rotation of the driven device 200, since the flexible electrical connector 500 is located in the central hole of the rotating shaft 230, the rotation of the driven device 200 can avoid the flexible electrical connector 500 from being wound to cause damage, which can certainly prolong the service life of the electronic device and reduce the failure rate of the power supply connection of the driven device 200.

The embodiment of the utility model discloses among the electronic equipment, actuating mechanism 300 includes rack subassembly 320, and rack subassembly 320 includes rack 321 and rack support 322 described above, rack 321 can set up on rack support 322, and rack support 322 fixes in casing 100, and is concrete, and rack support 322 can fix in casing 100 through screw 325, and is concrete, and rack support 322 can fix on mainboard 400 in casing 100 through screw 325.

In a general case, the decelerator 330 may be a gear decelerator.

Referring to fig. 10, in a preferable embodiment, 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 avoiding opening 410, the rack bracket 322 may be fixed at an edge of the avoiding opening 410, the rack 321 is located on one side of the driven device 200, and the driven device 200 is located in the avoiding opening 410 under the condition that the driven device 200 is located in the casing 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 the present embodiment, 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 casing 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 casing 100 through the through hole 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.
