Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric connection structure, specifically relates to a dynamic electric connection structure and electronic device. BACKGROUND

[0002] In electronic devices such as sensors, signal transmission is one of the core technologies, and stable signal transmission is the basis for accurate measurement of sensors. The stability and service life of the electric connection structure, which is the carrier for realizing signal transmission, directly affect the performance of the sensor. In some electronic devices, electric connection needs to be achieved between modules that move relative to each other. These electric connections need to be achieved using a dynamic electric connection structure. Existing dynamic electric connection structures such as conductive slip rings often use two conductive bodies that abut each other, with one conductor sliding along the surface of the other conductor to achieve electric connection. However, this type of dynamic electric connection structure can only achieve static electric connection and signal transmission (two electric connection structures are relatively stationary), and cannot achieve dynamic electric connection and signal transmission (one of the electric connection structures is multiple and in different spatial positions, or two electric connection structures move relative to each other). SUMMARY

[0003] To overcome the shortcomings of the prior art, the purpose of the utility model is to provide a dynamic electric connection structure that can achieve dynamic electric connection between one electric connection structure and multiple other electric connection structures in different spatial positions.

[0004] To solve the above problems, the utility model adopts the following technical scheme: a dynamic electric connection structure, comprising a plurality of first electric connection structures, a conductive rotary joint, a second electric connection structure and a driving mechanism, the plurality of first electric connection structures are arranged according to a certain trajectory, the conductive rotary joint is rotationally arranged on the driving mechanism, the second electric connection structure is connected with the driving mechanism, the second electric connection structure abuts against the conductive rotary joint, and the conductive rotary joint and the second electric connection structure can move along the arrangement trajectory of the first electric connection structures under the driving of the driving mechanism, so that the conductive rotary joint abuts against the plurality of first electric connection structures one by one.

[0005] Compared with the prior art, the beneficial effects of the utility model lie in that the first electric connection structure and the second electric connection structure are connected through the rotatable conductive swivel, the conductive swivel and the second electric connection structure can be in contact or separated from the multiple first electric connection structures under the driving of the driving mechanism, so that the second electric connection structure can realize dynamic electric connection with the multiple first electric connection structures in different positions. When the conductive swivel is in contact with the first electric connection structure, the conductive swivel will rotate under the action of the friction between the first electric connection structure and the conductive swivel, the sliding between the first electric connection structure and the second electric connection structure is changed into the rolling between the first electric connection structure and the conductive swivel, thereby reducing the friction loss of the first electric connection structure and prolonging the service life of the conductive structure to a certain extent.

[0006] The dynamic electric connection structure, the first electric connection structure is the elastic structure.

[0007] The dynamic electric connection structure, the second electric connection structure is the elastic structure.

[0008] The dynamic electric connection structure, the first electric connection structure and the conductive swivel abut one end of the hook shape.

[0009] The dynamic electric connection structure, the second electric connection structure and the conductive swivel abut one end of the hook shape.

[0010] The dynamic electric connection structure, multiple first electric connection structures are divided into multiple groups, multiple first electric connection structures are arranged side by side, multiple conductive swivels and second electric connection structures are arranged side by side on the driving mechanism, the number of the conductive swivel and the second electric connection structure corresponds to the group number of the first electric connection structure, multiple second electric connection structures and multiple conductive swivels correspond one by one and abut, multiple conductive swivels abut with each first electric connection structure in multiple first electric connection structures under the driving of the driving mechanism.

[0011] The dynamic electric connection structure, multiple conductive swivels can rotate independently.

[0012] An electronic device comprises the dynamic electric connection structure.

[0018] 100 first electrical connection structure, 200 conductive rotary ring, 210 rotating shaft, 300 second electrical connection structure. DETAILED DESCRIPTION

[0019] The embodiments of the present application will be described in detail below with reference to the drawings. Figure 1 The embodiments of the present application provide a dynamic electrical connection structure, which comprises a plurality of first electrical connection structures 100, a conductive rotary ring 200, a second electrical connection structure 300 and a driving mechanism (not shown in the figure). The conductive rotary ring 200 is rotationally arranged on the driving mechanism, the second electrical connection structure 300 is connected with the driving mechanism, the plurality of first electrical connection structures 100 are arranged according to a certain trajectory, the second electrical connection structure 300 abuts against the conductive rotary ring 200, and the conductive rotary ring 200 and the second electrical connection structure 300 can move along the arrangement trajectory of the first electrical connection structure 100 under the driving of the driving mechanism, so that the conductive rotary ring 200 abuts against the plurality of first electrical connection structures 100 one by one.

[0020] The dynamic electrical connection structure can be used to electrically connect a plurality of first-type electronic modules, such as a plurality of sensors, with the second-type electronic module, such as a control circuit. The driving mechanism controls the movement of the conductive rotary ring 200 and the second electrical connection structure 300 along the arrangement trajectory of the first electrical connection structure 100, so that the conductive rotary ring 200 abuts against the plurality of first electrical connection structures 100 one by one, and a plurality of sensors at different positions are electrically connected with the control circuit through the corresponding first electrical connection structure 100, the conductive rotary ring 200 and the second electrical connection structure 300 one by one, thereby realizing the dynamic electrical connection between the plurality of sensors and the control circuit. Since the conductive rotary ring 200 is rotationally arranged on the driving mechanism, when the conductive rotary ring 200 contacts the first electrical connection structure 100, the conductive rotary ring 200 will rotate under the action of the friction between the conductive rotary ring 200 and the first electrical connection structure 100, thereby converting the sliding between the first electrical connection structure 100 and the second electrical connection structure 300 into the rolling between the first electrical connection structure 100 and the conductive rotary ring 200, thereby reducing the friction loss of the first electrical connection structure 100, and prolonging the service life of the dynamic electrical connection structure to a certain extent.

[0021] It can be understood that the first electric connection structure 100, the conductive rotating ring 200 and the second electric connection structure 300 are all made of a conductor material, and the arrangement track of the first electric connection structure 100 can be set according to actual needs, which can be arranged in a straight line or can enclose a circle. Correspondingly, the driving mechanism can be a linear driving mechanism composed of a screw pair and a motor, or a rotary driving mechanism composed of a motor.

[0022] In some embodiments, in order to ensure that the first electric connection structure 100 and the second electric connection structure 300 can be tightly abutted with the conductive rotating ring 200 during movement and ensure the reliability of the electric connection structure, the first electric connection structure 100 and the second electric connection structure 300 are both elastic structures made of a conductive metal. When the first electric connection structure 100 and the second electric connection structure 300 abut with the conductive rotating ring 200, slight deformation occurs. The first electric connection structure 100 and the second electric connection structure 300 are tightly attached to the peripheral surface of the conductive rotating ring 200 under the action of the elasticity generated by the deformation, thereby ensuring the reliability of the electric connection. Referring to Figure 1 In the present embodiment, the end of the first electric connection structure 100 and the second electric connection structure 300 abutting with the conductive rotating ring 200 is hook-shaped, and the outer surface of the hook of the hook is abutted with the peripheral surface of the conductive rotating ring 200.

[0023] Referring to Figure 2 In the present embodiment, the conductive rotating ring 200 is a circular ring made of a conductive metal, and is rotationally connected with the rotating shaft 210. The rotating shaft 210 is fixedly connected with the driving mechanism. It can be understood that in some embodiments, the dynamic electric connection structure is required to supply power or transmit signals for multiple channels of the electronic module. Referring to Figure 3 The first electric connection structure 100 is divided into multiple groups, and the multiple groups of the first electric connection structure 100 are arranged side by side. The peripheral surface of the rotating shaft 210 is provided with a number of conductive rotating rings 200 corresponding to the number of groups of the first electric connection structure 100. The driving mechanism is correspondingly provided with a number of second electric connection structures 300 corresponding to the number of groups of the first electric connection structure 100. The multiple second electric connection structures 300 correspond one by one to the multiple conductive rotating rings 200 and abut. When the driving mechanism drives the second electric connection structure 300 and the conductive rotating ring 200 to move along the arrangement track of the first electric connection structure 100, the multiple conductive rotating rings 200 abut with the multiple groups of the first electric connection structure 100 one by one, thereby realizing the switching of multiple multi-channel electronic modules.

[0024] The electronic device of the embodiment of the present application comprises the dynamic electrical connection structure and the two types of electronic modules, and the second type of electronic module is dynamically electrically connected with the plurality of first type of electronic modules through the dynamic electrical connection structure.
