Abstract

The present invention discloses an anti-heavy-pressure mechanism for a sliding rail used for moving and aligning a wireless charging transmitting coil board, which comprises a lifting base and a supporting plate. The lifting base includes a lifting sleeve and a base plate. The lifting sleeve is fixedly installed on the upper surface of the base plate. An airbag lifting platform is fixedly installed on the upper surface of the base plate inside the lifting sleeve. A top plate is fixedly installed at the top of the airbag lifting platform. The supporting plate is fixedly installed at the top of the lifting sleeve. A groove is formed in the supporting plate. Two groups of connecting plates are symmetrically arranged on the bottom surface of the groove. Four groups of elastic support components are symmetrically arranged between the connecting plates and the supporting plate. The T-shaped support column sequentially slides through the supporting plate and the connecting plate and extends to the bottom of the connecting plate, effectively avoiding the hard extrusion between the wireless charging transmitting coil board body and the light sliding rail, ensuring the normal use of the light sliding rail, and thus ensuring that the wireless charging transmitting coil board body completes the normal alignment work and then conducts charging.

Description

Technical Field

[0001] The present invention belongs to the technical field of wireless charging, and particularly relates to an anti-heavy-pressure mechanism for a slide rail for moving and aligning a wireless charging transmitting coil board. Background Art

[0002] Wireless charging technology is derived from wireless power transmission technology. Wireless power transmission, also known as wireless energy transmission or wireless power transmission, mainly realizes non-contact power transmission through electromagnetic induction, electromagnetic resonance, radio frequency, microwave, laser and other means. Electric vehicle wireless charging technology transmits electrical energy to the power pickup mechanism of the vehicle receiver running within a certain range on the ground in the form of a high-frequency alternating magnetic field through a power supply guide rail buried underground, and then supplies power to the in-vehicle energy storage device, enabling electric vehicles to carry a small number of battery packs and extending their cruising range;

[0003] To protect the wireless charging transmitting coil board, the wireless charging transmitting coil board will be hidden in the device for protection when not in use. When in use, it is moved out to realize the moving and aligning function of the wireless charger. However, the sliding connection friction of the wireless charging transmitting coil board in the existing device is relatively large. However, if the structure that increases the smoothness lacks an anti-heavy-pressure mechanism, it is easily damaged when subjected to external heavy pressure, directly resulting in the inability of the wireless charging transmitting coil board to complete the alignment and use.

[0004] Therefore, we propose an anti-heavy-pressure mechanism for a slide rail for moving and aligning a wireless charging transmitting coil board to solve the problems existing in the prior art. By adding two groups of light slide rails, the smoothness of the charging transmitting coil board during moving and aligning is improved; an elastic support component is added at the bottom of the light slide rail. When the wireless charging transmitting coil board is subjected to external heavy pressure, the wireless charging transmitting coil board presses the light slide rail, and the light slide rail compresses the spring, avoiding the hard extrusion between the wireless charging transmitting coil board and the light slide rail, ensuring the normal use of the sliding connection device, and thus ensuring that the wireless charging transmitting coil board completes the normal alignment work and then charges. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-heavy-pressure mechanism for a slide rail for moving and aligning a wireless charging transmitting coil board to solve the problem that the sliding connection friction of the wireless charging transmitting coil board in the existing device is relatively large. However, if the structure that increases the smoothness lacks an anti-heavy-pressure mechanism, it is easily damaged when subjected to external heavy pressure, directly resulting in the inability of the wireless charging transmitting coil board to complete the alignment and use as mentioned in the above background art.

[0030] The support plate 2 is fixedly installed on the top of the lifting sleeve 101. A groove 201 is opened in the support plate 2. Two groups of connecting plates 3 are symmetrically arranged on the bottom surface of the groove 201. Four groups of elastic support components 4 are symmetrically arranged between the connecting plates 3 and the support plate 2. The elastic support component 4 includes a T-shaped support column 401. The T-shaped support column 401 sequentially slides through the support plate 2 and the connecting plate 3 and extends to the bottom of the connecting plate 3.

Light rails 5 are fixedly installed on the upper surfaces of the connecting plates 3 inside the groove 201. Through grooves 202 are opened at the installation positions of the connecting plates 3 in the groove 201. The light rails 5 are fixedly installed in the through grooves 202. A wireless charging transmitting coil board body 6 is fixedly installed on the tops of the two groups of light rails 5. A gap 10 is provided between the lower surface of the wireless charging transmitting coil board body 6 and the upper surface of the support plate 2.

[0031] A rack 7 is fixedly installed on one side of the bottom of the wireless charging transmitting coil board body 6. A motor 8 is fixedly installed on the bottom surface of the support plate 2. A gear 9 is fixedly installed at the output shaft end of the motor 8. The gear 9 meshes with the rack 7. A positioning hole 203 is opened in the support plate 2. The output shaft end of the motor 8 penetrates through the positioning hole 203. A positioning plate 801 is fixedly connected at the installation position of the motor 8 and the support plate 2.

[0032] The lifting sleeve 101 includes a hollow column 1011, a first sleeve 1012 and a second sleeve 1013. The bottom of the hollow column 1011 is fixedly connected to the substrate 102. The first sleeve 1012 is slidably mounted on the outer wall of the hollow column 1011. The second sleeve 1013 is slidably mounted on the outer wall of the first sleeve 1012.

[0033] Embodiment 2

[0034] Different from Embodiment 1:

[0035] As Figure 6 , on the upper surfaces of the two groups of connecting plates 3 and located within the grooves 201, universal ball guides 11 are fixedly installed. The spherical surfaces of the universal ball guides 11 are in contact with the bottom surface of the wireless charging transmitting coil plate body 6.

[0036] Working principle: When in use, start the motor 8, the gear 9 rotates to drive the rack 7 to move, thereby driving the wireless charging transmitting coil plate body 6 to move. When moving, by adding two groups of light sliding rails 5, the smoothness of the wireless charging transmitting coil plate body 6 during moving and alignment is improved;

[0037] An elastic support assembly 4 is added at the bottom of the light sliding rail 5. When the wireless charging transmitting coil plate body 6 is subjected to an external force and bears heavy pressure, the wireless charging transmitting coil plate body 6 presses down on the light sliding rail 5, and the light sliding rail 5 compresses the spring 403, thereby generating a downward displacement, effectively avoiding hard extrusion between the wireless charging transmitting coil plate body 6 and the light sliding rail 5, ensuring the normal use of the light sliding rail 5, and thus ensuring that the wireless charging transmitting coil plate body 6 completes normal alignment work and then charges.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention.
