Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a rotation adjustment mechanism of an electric connector and a terminal device. Background Art

[0002] Nowadays, many electronic terminal devices are developing in the direction of being thinner and lighter for the sake of portability and better appearance. The extremely thin body certainly caters to the needs of current users. However, since electronic terminal devices generally need to be equipped with I / O sockets, and the development of connecting plugs that match the I / O sockets on the market is relatively lagging, the thinning and lightening of the connecting plugs cannot keep up with the changes in the electronic terminal device body. As a result, the thickness of the connecting plug exceeds the thickness of the shell of the terminal device equipped with the I / O sockets, such as Figure 10 The top of the connecting plug extends upward beyond the terminal device by a distance L1, and the bottom of the connecting plug extends downward beyond the terminal device by a distance L2. Therefore, when the connecting plug is inserted into the I / O socket, if the lower bottom surface of the connecting plug extends beyond the shell, the connecting plug will abut against the supporting surface where the terminal device is placed, thereby lifting up one side of the terminal device, causing the terminal device to be in a "seesaw" state. During use, the I / O socket end of the terminal device will be suspended on one side, causing it to shake during use. Summary of the Invention

[0003] The object of the present invention is to provide an electrical connector rotation adjustment mechanism and a terminal device, which can adjust the pitch angle of the connector on the terminal device according to needs to adjust the height of the connecting plug connected to the connector.

[0004] In order to achieve the above object, the present invention discloses an electrical connector rotation adjustment mechanism, which includes:

[0005] A connection substrate, which is used to install and fix a connector for electrical signal transmission;

[0006] A carrier frame, used for mounting and fixing the connection substrate;

[0007] A support base is arranged in the terminal device to which the connector belongs. The supporting frame is rotatably connected to the support base so that the supporting frame can drive the connecting substrate and the connector to rotate relative to the support base to adjust the pitch angle of the connector.

[0008] Preferably, a bearing groove is provided on the support seat, and a rotating shaft adapted to the bearing groove is provided on the bearing frame.

[0009] Preferably, an elastic retaining member is provided on the rotating shaft, and the elastic retaining member is used to provide an elastic retaining force for the supporting frame to be constantly kept in a certain state.

[0010] Preferably, it further comprises a driving mechanism connected to the rotating shaft, wherein the driving mechanism is used to drive the rotation of the rotating shaft.

[0011] Preferably, the driving mechanism includes a driven gear provided on the rotating shaft and a transmission shaft provided with a driving gear, and the driving gear is meshed with the driven gear.

[0012] Preferably, the terminal device includes a host and a display screen, and the host and the display screen are rotationally connected based on the transmission shaft.

[0017] Compared with the prior art, the above technical solution of the present invention provides the connector on the terminal device with an independently movable connecting substrate, which is rotatably connected to the support base through a supporting frame.

[0028] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0029] like Figure 1 and 6 This embodiment discloses a terminal device M, which can be a laptop computer, a drone, a robot vacuum cleaner, a tablet computer, or other household appliance. The terminal device M includes a connector M0, such as a USB female connector, for plugging and unplugging connections and transmitting electrical signals. The connector M0 is assembled based on a rotation adjustment mechanism to facilitate adjusting the pitch angle of the connector M0, thereby adjusting the height of a connecting plug P connected to the connector M0.

[0030] like Figures 1 to 4, the rotation adjustment mechanism includes a connecting substrate 1, a carrier 2 and a support seat 3. The connecting substrate 1 in this embodiment is a movable circuit board independent of the mainboard M3 of the terminal device M, which is used to install and fix the connector M0. The carrier 2 is used to install and fix the connecting substrate 1, and drive the movement of the connecting substrate 1. The support seat 3 is arranged in the terminal device M to which the connector M0 belongs. Specifically, in this embodiment, the support seat 3 is arranged on the M shell of the terminal device. For example, for a laptop computer, since the connector M0 is located in the D shell, the support seat 3 is arranged on the D shell. The support seat 3 is rotatably connected to the carrier 2, so that the carrier 2 can drive the connecting substrate 1 together with the connector M0 to rotate relative to the support seat 3 to adjust the pitch angle of the connector M0. It should also be noted that in this embodiment, the connector M0 is not limited to a female seat structure. The connector M0 and the connecting plug P only need to have a plug-in connection structure that cooperates with each other.

[0031] In this embodiment, when the bottom of the connecting plug P connected to the connector M0 on the terminal device M protrudes from the shell of the terminal device M and lifts up one side of the terminal device M, a rotational torque can be provided for the carrier 2, so that the carrier 2 rotates on the support base 3. The rotation of the carrier 2 will drive the connecting substrate 1 to rotate together with the connector M0, thereby changing the pitch angle of the connector M0, for example, from a horizontal state to an upward tilted state, thereby raising the height of the connecting plug P connected to the connector M0, so as to avoid the connection plug P from interfering with the supporting surface of the terminal device M and lifting up one side of the terminal device M, so that the terminal device M can be made thinner.

[0032] like Figure 3 and Figure 4 The support base 3 is provided with a bearing groove 30, and the carrier 2 is provided with a rotating shaft 20 adapted to the bearing groove 30. In this embodiment, the carrier 2 has a rotating shaft 20 at each end, and accordingly, two opposing support bases 3 are configured. The carrier 2 is mounted on the two support bases 3 based on the two rotating shafts 20 at both ends. When a rotational torque is applied to the rotating shaft 20, the carrier 2 rotates.

[0033] Furthermore, to prevent the support frame 2 from moving freely without cause, an elastic retaining member 4 is provided on the rotating shaft 20. The elastic retaining member 4 is used to provide an elastic retaining force to keep the support frame 2 in a constant state. In this embodiment, the elastic retaining member 4 is a torsion spring 4, one end of which is connected to the support seat 3, and the other end of the torsion spring 4 is connected to the rotating shaft 20. When the pitch angle of the connector M0 needs to be adjusted, sufficient rotational torque is applied to the support frame 2 to overcome the torsion force of the torsion spring 4, so that the connector M0 rotates into place.

[0034] Furthermore, in order to facilitate the rotation of the carrier 2 , the rotation adjustment mechanism in this embodiment further includes a driving mechanism connected to the rotating shaft 20 , and the driving mechanism is used to drive the rotation of the rotating shaft 20 .

[0035] Specifically, if Figure 3 and Figure 4 The drive mechanism includes a driven gear 21 disposed on a rotating shaft 20 and a transmission shaft 5 provided with a driving gear 50, wherein the driving gear 50 meshes with the driven gear 21. In this embodiment, the rotation of the transmission shaft 5 drives the driving gear 50 to rotate, and the rotation of the driving gear 50 synchronously drives the rotation of the driven gear 21. The rotation of the driven gear 21 drives the rotation of the rotating shaft 20, thereby driving the rotation of the carrier 2. This embodiment is easy to operate and facilitates the control of the rotation angle of the carrier 2.

[0036] For the driving mechanism of the above structure, the rotation of the transmission shaft 5 can be operated manually in cooperation with the relevant linkage mechanism, or the rotation of the transmission shaft 5 can be automatically driven by a motor.

[0037] Furthermore, for a terminal device M including a host M1 and a display screen M2, as shown in FIG. Figure 6 For example, in a laptop computer, the transmission shaft 5 can serve as the rotation axis between the host M1 and the display M2. That is, the host M1 and the display M2 are rotationally connected based on the transmission shaft 5. In this embodiment, since the transmission shaft 5 used to drive the support frame 2 to rotate serves as the rotation axis between the host M1 and the display M2, when the host M1 and the display M2 rotate, they can also drive the support frame 2 to rotate synchronously, thereby adjusting the pitch angle of the connector M0 to the desired state.

[0038] In addition, for the terminal device M including the host M1 and the display screen M2, during use, the display screen M2 is often rotated relative to the host M1 within a certain range of angles. For example, when the display screen M2 is rotated from closed to open to 180 degrees relative to the host M1, Figure 6 and Figure 7 , the host M1 is placed upward and forward, the top of the connecting plug P extends upward beyond the host M1 by a distance h1, and the bottom of the connecting plug P is at a distance h2 from the base of the host M1. The connecting plug P will not interfere with the supporting surface of the host M1, so there is no need to adjust the pitch angle of the connector M0. When the display screen M2 rotates from 180° to 360° relative to the host M1, Figure 8 and Figure 9 , the host M1 is placed downward and reversely, and the bottom of the connecting plug P extends downward over the host M1 by a distance h3. Therefore, the pitch angle of the connector M0 needs to be adjusted during this process, otherwise the connecting plug P will interfere with the supporting surface of the host M1.

[0039] To solve this problem, further improvements are made, such as Figure 4 and Figure 5 , a vacant portion 51 is provided on the rim of the driving gear 50 or the driven gear 21, so that the driving gear 50 and the driven gear 21 are discontinuously meshed to transmit power. Specifically, the vacant portion 51 corresponds to the state in which the host M1 is facing upward during the relative rotation of the display screen M2 and the host M1 (such as Figure 6 ), that is, the circumferential arc occupied by the vacant portion 51 is 180°. In this embodiment, the vacant portion 51 is located on the driving gear 50 of the transmission shaft 5, and the vacant portion 51 and the toothed portion 52 with teeth each occupy half of the rim of the driving gear 50.

[0040] Further, if Figure 1 The connector M0 is connected to the mainboard M3 of the terminal device M through a flexible connecting line 6 to facilitate the rotation of the connector M0.

[0041] In summary, if Figures 1 to 9 The present invention discloses a rotation adjustment mechanism for a terminal device M, through which a connector M0 installed on the terminal device M is assembled. Specifically, the connector M0 is installed on a connection substrate 1 that is independent of a mainboard M3 of the terminal device M. The connection substrate 1 is installed on a carrier 2. The carrier 2 is mounted on a support base 3 via a rotating shaft 20, so that the carrier 2 can drive the connector M0 to rotate to adjust its pitch angle, thereby achieving the purpose of adjusting the height of the connection plug P connected to the connector M0 and avoiding interference between the connection plug P and the supporting surface of the terminal device M. In addition, for the terminal device M having a structure of a host M1 and a display screen M2, and the host M1 and the display screen M2 can rotate 360 ​​degrees relative to each other, a linkage drive mechanism is also configured for the rotating shaft 20, so that when the relative state of the host M1 and the display screen M2 changes, the connector M0 is automatically adjusted to the desired position, which is convenient to use and effectively improves the user experience.

[0042] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
