[0059] The following is a further detailed description of specific embodiments of the present invention based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0060] like Figures 1 to 10 As shown, the waterproof surface mount power supply device of this embodiment includes a power supply track 100 and a power supply head 200 arranged on the power supply track 100.

[0061] The power supply track 100 includes a track body 101, a power supply groove 102, a strip-shaped conductive member 103 and a strip-shaped sealing member 104. The track body 101 is a strip extending along the length direction; the power supply groove 102 is arranged on the track body 101 and extends along the length direction; the strip-shaped conductive member 103 is arranged in the power supply groove 103 and extends along the length direction; the strip-shaped sealing member 104 is arranged in the power supply groove 103 and is located on the outside of the strip-shaped conductive member 103 and extends along the length direction. The above structure can obtain a strip-shaped power supply track 100 extending along the length direction, and the power supply groove 103 is sealed by the strip-shaped sealing member 104, thereby achieving waterproofing of the strip-shaped conductive member 103. The cross-section of the strip-shaped sealing member 104 can be any shape, such as circular, elliptical, rectangular or polygonal. In this embodiment, the cross-section of the strip-shaped sealing member 104 is circular with a diameter of 2mm to 3mm.

[0062] The power supply head 200 includes a mounting base 201, an external plug-in connector 203 and a power supply component 204; the mounting base 201 is movably arranged on the track body 101 and is provided with a sealed mounting cavity 202; the movable arrangement means that it is fixed in a direction perpendicular to the length of the track body 101 and can be relatively moved in the length direction; the external plug-in connector 203 is arranged on the mounting base 201 and is used to supply power to the electrical appliance, which can be a plug. , sockets, etc., with or without wires. In this embodiment, the external connector 203 is a waterproof socket with a plug wire 2031; the root of the power-taking component 204 is arranged in the installation cavity 202 and is electrically connected to the external connector 203. The power-taking component 204 is implemented in the sealed installation cavity 202 and is electrically connected to the external connector 203 to achieve a waterproof effect. The installation cavity 202 is sealed by laser after the box body 2021 and the cover body 2022 are buckled together. The sealed installation cavity 202 can also be directly produced by methods such as 3D printing. In this embodiment, a circuit board 2023 is also provided in the installation cavity 202, and the external connector 203 and the power collection component 204 are welded to the circuit board 2023 to achieve electrical connection; the main part of the power collection component 204 extends out of the installation cavity 202, squeezes open the strip seal 104, inserts into the power supply slot 102 and abuts against the strip conductive component 103, and the power collection component 204 abuts against the strip conductive component 103, thereby realizing contact power collection.

[0063] To facilitate installation, the power supply slot 102 extends through at least one end of the track body 101, and one end is sealed with an end cap 105. In this embodiment, the power supply slot 102 extends through both ends of the track body 101, with end caps 105 at both ends. One end also includes a plug connector 106 for connecting to an external power source. This structure eliminates the need for the power supply head 200 to be inserted vertically, instead allowing it to be inserted into the power supply slot 102 from the end of the track body 101, facilitating installation.

[0064] The power extraction component 204 needs to have a smaller cross-section so that the strip seal 104 can still have a good sealing effect after squeezing out the strip seal 104. For example, conductive sheets, conductive needles, etc. are used, which are generally made of metal materials with elasticity and fatigue resistance. The bent conductive sheets or conductive needles are elastic, so that the contact-type power extraction can be more stable. In this embodiment, the power extraction component 204 is a multi-section bent conductive elastic needle. Specifically, the conductive elastic needle 204 includes a contact section 2041 and a connecting section 2043. The contact section 2041 is inserted into the power supply slot 102 and is provided with at least one first bend 2042 along the length direction of the power supply slot 102. The first bend 2042 abuts against the strip conductive component 103; one end of the connecting section 2043 is connected to one end of the first bend section 2041, and the other end extends into the installation cavity 202 to be electrically connected to the external connector 203.

[0065] The cross section of the conductive spring needle can be of various shapes. In this embodiment, a circular shape is used with a diameter of 0.3 mm to 1.0 mm.

[0066] In order to prevent the conductive spring pins 204 from being easily deformed, in this embodiment, each conductive spring pin 204 is provided with two connecting sections 2043 , which are respectively connected to the two ends of the contact section 2041 .

[0067] Multiple first bends 2042 are arranged continuously to form multiple contact points. The contact section 2041 has two consecutive first bends 2042 to form a roughly "W" shape. The first bends 2042 can be directly connected or connected through straight sections 2048.

[0068] The power supply groove 102 can be a straight linear groove in the depth direction so that it can be inserted from above, or it can be provided with a bend in the depth direction for a better sealing effect. In this embodiment, the power supply groove 102 is provided with at least one bend 1021 along the depth direction. Specifically, the power supply groove 102 is provided with a bend 1021 along its depth direction, and the strip seal 104 is provided at this bend 1021. In order to match these bend 1021 structures, the connecting section 2043 includes an extension 2044, a second bend 2045, a third bend 2046, and a fourth bend 2047. This arrangement can obtain a contact section 2041 with better elasticity. One end of the extension portion 2044 is located in the installation cavity 202, and the other end extends out of the installation cavity 202; one end of the second bend 2045 is connected to the extension portion 2044, and the other end extends along the length direction of the track body 101; one end of the third bend 2046 is connected to the free end of the second bend 2045, and the other end is stuck in the outside of the bend 1021; one end of the fourth bend 2047 is connected to the free end of the third bend 2046, and the other end is stuck in the inside of the bend 1021 and connected to one end of the contact segment 2041.

[0069] The present invention is mainly used for obtaining power from shelves. The cross-section of the track body 101 can be of any shape, one side of which will be used to be attached to the surface of the shelf. Therefore, considering the angle of reducing the volume, in this embodiment, the track body 101 is a flat structure, including an upper surface 1011, a lower surface 1012 and two sides 1013. The lower surface 1012 can be provided with magnets, double-sided tape, etc. for fixing to the surface of the shelf. The flat structure occupies a very small volume and is more beautiful and neat. In this embodiment, the power supply slot 102 is "L"-shaped, opening from the upper surface 1011 and extending perpendicularly to the upper surface 1011. After bending, it extends toward the middle of the track body 101. The bent portion is roughly at a right angle, but is not limited to a right angle, and can also be an acute angle or an obtuse angle.

[0070] like Figure 11 and 12 As shown, in another embodiment, the power supply groove 102' is a linear groove, which opens from the side 1013' and extends toward the middle of the rail body 101'. The contact section 2041' is inserted into the power supply groove 102' from the side.

[0071] To enhance waterproofing, a sealing ring 205 is provided on the outer surface of the mounting base 201, located around the portion where the power pickup 204 extends from the mounting cavity 202. The sealing ring 205 rests against the rail body 101, thereby providing waterproofing for the portion where the power pickup 204 extends from the mounting cavity 202. Furthermore, the sealing ring 205 includes a first protrusion 2051 and a second protrusion 2052 that engage the power supply slot 102 and abut against the strip seal 104.

[0072] There are many ways to fix the power supply head 200. The friction generated by the power supply slot 102 and the power supply member 204 can achieve a positioning effect. Adding a locking device can improve the stability of the fixation. The power supply head 200 also includes a locking device 206 that fixes the mounting seat 201 to the track body 101.

[0073] The locking device 206 includes a movable seat 2061 and a locking member 2063. The movable seat 2061 is movably set on the track body 101. The movable setting of this embodiment is achieved by a snap-fit ​​structure, and can also be achieved by other forms. A track 2062 is provided, the moving direction of which is perpendicular to the length direction of the track body 101. The track 2062 of this embodiment is a frame surrounded by the movable seat 2061, and the mounting seat 201 is set on the track 2062; the locking member 2063 is movably set on the movable seat 2061, and is located above the mounting seat 201 to press and fix the mounting seat 201 on the track body 101. The locking member 2063 can be threaded fastening, snap-fit ​​fastening, slider locking, etc. In this embodiment, the locking member 2063 is a cam structure, which is rotatably mounted on the movable seat 2061. The cam structure is convenient for locking and unlocking.

[0074] In order to reduce the friction on the power supply head 200 after unlocking, the power supply head 200 also includes an elastic reset module 207 provided on the mounting seat 201 for separating the mounting seat 201 from the rail body 101 after the locking device 206 is unlocked. The elastic reset module 207 can be a bent spring, or a spring, etc. In this embodiment, the elastic reset module 207 includes a reset spring 2071 and a top column 2072. The reset spring 2071 is provided on the mounting seat 201; the top column 2072 is provided between the reset spring 2071 and the mounting seat 201, and partially extends out of the mounting seat 201 to abut against the rail body 101. Specifically, a mounting hole 2011 is provided in the middle of the mounting seat 201 of this embodiment to provide the elastic reset module 207.

[0075] Generally, both positive and negative power are required. Therefore, in this embodiment, two sets of power supply slots 102, strip-shaped conductive members 103, and strip-shaped sealing members 104 are provided, and correspondingly, two power extraction members 204 are provided. Specifically, the power supply slots 102, strip-shaped conductive members 103, and strip-shaped sealing members 104 are provided in two symmetrically arranged sets, and the two power extraction members 204 are also arranged symmetrically, serving as the positive and negative poles, respectively. The two sets of power supply slots 102 are arranged in opposite directions, bringing the two strip-shaped conductive members 103 closer together, thereby reducing the width of the track body 101.

[0076] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
