[0009] The technical solutions of the present application are described in more detail below with reference to the attached drawings and embodiments.

[0010] To better understand the purpose, structure and function of the present application, the following detailed description, together with the attached drawings, provides an explanation of a modular electrical connection device and a cabinet unit of the present application.

[0011] Regarding the Fig. Figures 1 to 15 show that the present application comprises a modular power connection device 300 configured for use in conjunction with the furniture 100 and the power consumption device 200 installed on the furniture 100. Each set of modular power connection devices 300 comprises a power busbar 10, a power supply mechanism 20, and a power transmission mechanism 30, wherein the power supply mechanism 20, the power busbar 10, and the power transmission mechanism 30 are connected in series, thereby enabling electrical energy to be transferred from the power supply mechanism 20 via the power busbar 10 to the power transmission mechanism 30 and to the power consumption device 200. In other words, the power supply device, the power supply mechanism 20, the power busbar 10, the power transmission mechanism 30, and the power consumption device 200 form a circuit.

[0012] In some embodiments, the furniture 100 may specifically be cabinet furniture, such as wardrobes, kitchen cabinets, shoe cabinets, bookcases and the like; in some other embodiments, the furniture 100 may also be a television cabinet, a combined cabinet for the background wall, a bedside table, a dressing table, a desk, a work table, a display shelf, a storage shelf or the like, provided that the power busbar 10 can be attached to the furniture panel and there is space in the furniture for accommodating the power consumption device 200; the present application does not restrict the specific type of furniture 100.

[0013] For the sake of simplicity, "furniture 100" can refer specifically to the cabinet 80. Several cabinets 80 can be assembled and connected to each other as needed by the user to form a complete cabinet unit 100. The user can manually assemble cabinets 80 of different sizes to create their own design style. In some embodiments, the power consumption device 200 comprises one or a combination of several components, such as a light bulb, a sensor component, a socket component, a USB charging component, a drive motor component, a display component, a Bluetooth speaker, or a charger. The accompanying drawings of this application show a light bulb. The user can install a light bulb in each cabinet 80 or a light bulb on any of the cabinet units 80 as needed to provide area lighting.

[0014] By centrally installing the power busbar 10 on the furniture 100 and using the power transmission mechanism 30 to connect each power consumption device 200 to the power busbar 10, the originally scattered power supply lines can be evenly accommodated within the power busbar 10, thereby reducing the need for individual wiring and connection operations, simplifying the entire wiring structure of the furniture 100, improving installation efficiency and reducing the wiring error rate.

[0015] In some embodiments, the busbar 10 is configured to be cut to a target length in the longitudinal direction, i.e., the length of the busbar 10 essentially corresponds to the height of the cabinet 80. During production and processing, the factory can manufacture the cabinet 80 and the busbar 10 to a uniform length. After receiving the customization requirements requested by the user, the busbar 10 of uniform length is cut to size according to the height of the customer-specific cabinet 80 using tools such as a cutting machine to adapt it to the height of the customer-specific cabinet 80.After the appropriate number of cabinets 80 and modular power connection devices 300 have been transported to the user, the user can mount the cut-off power busbar 10 directly at the target mounting position of the furniture 100 and thus easily implement the individual customization requirements of the cabinet furniture 100.

[0016] In some embodiments, the power supply mechanism 20 is designed so that it can be selectively positioned on the power busbar 10 and that the power supply mechanism 20 can continuously supply the power busbar 10 with electrical energy, that is, the power transmission structure is used to transfer external electrical energy to the entire power busbar 10, the power transmission mechanism 30 and the corresponding power consumption device 200.

[0017] In some embodiments, at least one power transmission mechanism 30 is provided, each power transmission mechanism 30 being designed to allow detachable installation at a target position on the busbar 10 and connection to a corresponding power consumption device 200. According to the user's customer requirements, the power consumption device 200 can be mounted at any point along the longitudinal direction of the busbar 10; for example, a light fixture can be mounted at the highest point. For example, a charging socket can be installed at mid-height, or a Bluetooth speaker or wireless charging station at the lowest point. The user simply needs to mount the appropriate number of power transmission mechanisms 30 at the corresponding positions on the busbar 10; operation is simple and straightforward.

[0018] To reduce wiring effort, the busbars 10 of each set of modular power connection devices 300 can be mounted and connected end-to-end. In other words, once the cabinets 80 are mounted at the same vertical height, the busbars 10 run in the same straight line across all cabinets 80. Since all power consumption devices 200 can be directly connected electrically to the power transmission mechanism 30, and the entire circuit is connected via the busbar 10, the number of external power supply lines for the power consumption devices 200 is effectively reduced. Furthermore, because adjacent busbars 10 are interconnected, wiring is simplified, allowing them to be installed sequentially in one direction. This reduces the error rate during installation and improves installation efficiency.

[0019] Due to the possibility of shortening the busbar 10, the flexibility to mount the power transmission mechanism 30 in different positions, and the use of a power supply mechanism 20 to connect the busbar 10, the power transmission mechanism 30 and the power consumption device 200 in series in the corresponding cabinet 80, the individual design requirements of the user for the furniture 100 can be met, and the installation concept is simple.Once the user has received the furniture 100, the installer can assemble it in one step. In contrast to similar technologies where the circuits of various electrical devices must be taken into account, the modular power connection device 300 of the present application eliminates the need to consider circuit connection problems. In other words, the installer does not need any electrical knowledge, and even the user can enjoy the fun of assembling the furniture 100 himself.

[0020] In some embodiments, where asynchronous control is required for each power consumption device 200, the corresponding modular power connection device 300 has an independent power supply mechanism 20, each independent power supply mechanism 20 being arranged at one end of the power busbar 10, for example at the bottom or top of the cabinet 80, to asynchronously control different power consumption devices (200); this method can further enhance the user's DIY design style by, for example, enabling the creation of different flowing, scanning, and gradient color effects through different lighting lamps.

[0021] In some other embodiments, if synchronous control of each power consumption device 200 is required, all modular power connection devices 300 in the same mounting direction can use the same power supply mechanism 20, provided that adjacent power busbars 10 are electrically connected; this method further reduces the wiring effort and increases the structural compactness of the modular power connection device 300.

[0022] In some embodiments, in combination with Fig. 3 and Fig. 4, the busbar 10 comprises a base plate 11, a side plate 12, a first conductor strip 13 and a second conductor strip 14, wherein two side plates 12 are provided and arranged symmetrically at both ends of the base plate 11, wherein the base plate 11 and the side plates 12 form a mounting space 121 for receiving the power transmission mechanism 30, wherein each side plate 12 is also provided with a notch 122 extending along its longitudinal direction; wherein the first conductor strip 13 and the second conductor strip 14 are arranged relatively firmly in the corresponding notch 122 and do not touch each other, the current transmission mechanism 30 is arranged in the mounting space 121 and can be in contact with the first conductor strip 13 and the second conductor strip 14 respectively.

[0023] Specifically, the notch 122 is an isosceles trapezoid, and the openings of the notch 122 are arranged opposite each other, so that part of the first conductor strip 13 and the second conductor strip 14 can be exposed. The first conductor strip 13 and the second conductor strip 14 are also designed as isosceles trapezoids, which makes it easier for the first conductor strip 13 and the second conductor strip 14 to establish an electrical loop connection with the current transmission mechanism 30.

[0024] It should be noted that if modular power connection devices 300 in the same mounting direction all use the same power supply mechanism 20, two adjacent first conductor strips 13 come into contact with each other and two adjacent second conductor strips 14 also come into contact with each other, this enables the circuit connection between adjacent modular power connection devices 300.

[0025] In some embodiments, in combination with Fig. 4 and Fig. 7, the busbar 10 further comprises a limiting section 15, which is arranged on one side of the base plate 11 and extends in the longitudinal direction of the base plate 11, and the limiting section 15 and the side plate 12 form a wiring space 151, which serves to accommodate the power supply line 70 of the power supply mechanism 20 of other modular power connection devices 300.

[0026] Due to the multi-layered cabinet 80, the power supply mechanism 20, corresponding to each layer of the cabinet 80, must be connected to the power supply device via the corresponding power supply line 70. To reduce the exposed power supply line 70, this application utilizes the wiring space 151 to conceal the power supply line 70. During installation, the power supply line 70 can be fed sequentially into all wiring spaces 151 in the same direction.

[0027] In some embodiments, two boundary sections 15 are provided, which are arranged symmetrically on both sides of the base plate 11 and form two sets of wiring spaces 151.

[0028] In the present embodiment, two sets of wiring compartments 151 are used to increase the space for accommodating wires and to facilitate the installation of power supply lines 70, thereby reducing the number of power supply lines 70 in the same wiring compartment 151. More specifically, in some embodiments, if an asynchronous control power supply is required, the power supply line 70 needed for the asynchronous control can be arranged in the wiring compartment 151 inside the lower power busbar 10 to reduce the need for additional groove and wiring on the furniture.

[0029] In some embodiments, the base plate 11, the side plate 12 and the boundary section 15 are formed in one piece to increase the structural stability of the busbar 10.

[0030] In some embodiments, in combination with Fig. 4 and Fig. 7. Several non-slip grooves 16 are also provided on the outside of the busbar 10. This improves the surface roughness of the busbar 10, thereby increasing the friction of the busbar 10 when it is embedded in the furniture 100, which facilitates a stable connection between the busbar 10 and the furniture 100.

[0031] In some embodiments, in combination with Fig. 6 and Fig. 7, the base plate 11 is provided with a release hole 111, the furniture 100 is provided with a mounting hole 1001, and the power transmission mechanism 30 comprises a first power pickup socket component 31 and a power pickup head component 32, which are connected to each other, the first power pickup socket component 31 is detachably mounted on the power busbar 10, and the power pickup head component passes through the release hole and is electrically connected to the power consumption device 200.

[0032] It should be noted that the release hole 111 and the mounting hole 1001 must be drilled with a drill after receiving the user's customer-specific requirements in order to obtain the mounting hole 1001 of the cabinet 80 and the release hole 111 of the busbar 10 so that they can be transported to the user's place of use. The user can then install the modular power connection device 300 directly via the release hole 111 and the mounting hole 1001.

[0033] In some embodiments, the first current pickup socket component 31 and the current pickup head component 32 can also be designed as a one-piece structure, i.e., the first current pickup socket component 31 and the current pickup head component 32 are permanently connected to each other in the factory state and cannot be disassembled during use in order to reduce the assembly processes and improve the connection reliability of the current transmission mechanism 30.

[0034] In some other embodiments, the first current pickup socket component 31 and the current pickup head component 32 are detachably connected to each other, in combination with Fig. 7 and Fig. 8 includes the first power pickup socket component 31 as follows: a first slide 40 which has a side chamber 401 and allows movement along the assembly space 121; a first conductive plate 41, which is arranged on one side of the side chamber 401 and can touch the first conductor strip 13 in order to be switched with it; a second conductive plate 42, wherein the second conductive plate 42 is arranged symmetrically with the first conductive plate 41 on the other side of the side chamber 401 and can be in contact with the second conductor strip 14 in order to be switched with it; a first plug end 43 comprising a first insertion end 431 and a second insertion end 432, wherein the first insertion end 431 is electrically connected to the first conductive plate 41, wherein the second insertion end 432 is electrically connected to the second conductive plate 42, wherein the first insertion end 431 and the second insertion end 432 extend outwards and pass through the release hole 111 to establish an electrical connection with the current pickup head component 32.

[0035] In the present embodiment, two avoidance holes 402 are arranged symmetrically on the first slide 40. The first conductive plate 41 and the second conductive plate 42 have the same structure. The first conductive plate 41 comprises a first connecting section 411, a contact section 412, and a second connecting section 413, which are connected sequentially. The first slide 40 has two side chambers 401. The first connecting section 411 and the second connecting section 413 are each rigidly connected to the corresponding side chamber 401. The contact section 412 extends through the avoidance hole 402 and contacts the first conductor strip 13. Similarly, the contact section 412 of the second conductive plate 42 extends through the corresponding avoidance hole 402 and comes into contact with the second conductor strip 14. The first conductive plate 41 and the second conductive plate 42 do not touch each other.

[0036] The first conductive plate 41 can be electrically connected to the first plug-in end 431 via a wire or a piece of metal (not shown), the second conductive plate 42 can be electrically connected to the second plug-in end 432 via a wire or a piece of metal (not shown), in other words, the first power-receiving socket component 31 forms a plug structure.

[0037] Specifically, an insulating layer or a slot is provided between the first insertion end 431 and the second insertion end 432 to prevent them from coming into contact with each other; the first insertion end 431 and the second insertion end 432 are extended coaxially.

[0038] In one embodiment as in Fig. As shown in Figure 10, the current-collecting head component 32 comprises a first socket end 33, wherein the first socket end 33 is provided with a first insertion hole 331 and a second insertion hole 332, the first insertion hole 331 serving to receive the first plug-in end 431, such that the first plug-in end 431 is electrically connected to the first insertion hole 331, and the second insertion hole 332 serving to receive the second plug-in end 432, such that the second plug-in end 432 is electrically connected to the second insertion hole 332; the first socket end 33 comprises a first housing 50, a first conductive socket 51 and a second conductive socket 52, the first conductive socket 51 being electrically connected to the first insertion hole 331; the second conductive socket 52 being electrically connected to the second insertion hole 332.

[0039] With reference to Fig. Figure 10 shows that in the present embodiment the first socket end 33 further comprises two symmetrically arranged connecting metal pieces 58, wherein the two connecting metal pieces 58 are firmly attached to an end of the first housing 50 facing away from the first current-receiving socket component 31, and the two connecting metal pieces 58 do not touch each other, the two connecting metal pieces 58 are each electrically connected to the first conductive socket 51 and the second conductive socket 52 in order to bring out their electrical leads in order to establish a conductive connection with subsequent circuits.

[0040] In other words, the power pickup head component 32 as a whole forms a socket structure (female connector) for interacting and joining with the plug structure (male connector) of the first power pickup socket component 31 to establish a conductive connection between the two.

[0041] Specifically, an insulating layer or a slot is provided between the first conductive socket 51 and the second conductive socket 52 to prevent them from coming into contact with each other; the first conductive socket 51 and the second conductive socket 52 are arranged coaxially.

[0042] It goes without saying that in connection with Fig. 11 and Fig. 12 The first current pickup socket component 31 and the current pickup head component 32 are mounted on top of each other by a sliding fit to form a current conduction path. Therefore, the relative positions of the first current pickup socket component 31 and the current pickup head component 32 can be adjusted at the release hole 111 according to the different thicknesses of the plate, thereby flexibly changing the contact area between the two and establishing an electrical connection without affecting the reliability of the power supply. In other words, the first current pickup socket component 31 and the current pickup head component 32 of the present application can be adapted to plates of different thicknesses, such as wooden boards of different thicknesses.Since the electrical contact parts of the first current-collecting socket component 31 and the current-collecting head component 32 are located within the hole space of the release hole 111 in the assembled state and are shielded by the plate, the current-carrying contact surface is not directly exposed to the outside world, making it difficult for external personnel to touch it directly, thus reducing the risk of accidental electric shock and increasing electrical safety.

[0043] In some embodiments, in combination with Fig. 13, Fig. 14 and Fig. 15, the power transmission mechanism 30 further comprises a device-side connection seat component 34, via which the power pickup head component 32 is electrically connected to the power consumption device 200, the device-side connection seat component 34 comprises the following: a second housing 53, which is used for mounting on the power consumption device 200; a first insertion pin 54, which is arranged on the second housing 53 and serves to establish an electrical connection with the first conductive socket 51; a second insertion pin 55, which is arranged on the second housing 53 and serves to establish an electrical connection with the second conductive socket 52; wherein the first insertion pin 54 and the second insertion pin 55 are used to supply power to the power consumption device 200.

[0044] It should be noted that the second housing 53 can be assembled from two shells that engage with each other by snapping them together. One end of the first insertion pin 54 and the second insertion pin 55 are exposed at one end of the second housing 53 to establish a conductive connection with the current-collecting head component 32.

[0045] In some embodiments, such as in Fig. As shown in Figure 14, the device-side connection seat component 34 also comprises two conductive connecting elements 59, each electrically connected to the other end of the first insertion pin 54 and the second insertion pin 55, the conductive connecting element 59 having a piercing end 57 to establish an electrical connection with the power supply line of the power consumption device 200.

[0046] In the present embodiment, the conductive connecting element 59 further comprises a straight end 591, and the rear section of the straight end 591 is provided with at least one triangular piercing end 57. During assembly, the piercing end 57, due to its sharpness, can pierce the wire at the corresponding location of the power consumption device 200 and thus establish a conductive connection with the power consumption device 200.

[0047] It should be noted that each conductive connecting element 59 is configured to be electrically connected to the power supply line or power supply terminal of the power consumption device 200, for example by means of screw terminals, crimp terminals or plug terminals, and the present application does not restrict this.

[0048] In some embodiments, in combination with Fig. 8 and Fig. 9, the power transmission mechanism 30 further comprises first snap seats 44 which each snap into the first carriage 40 and the power busbar 10 to securely mount the first power transmission mechanism 30 in the target position.

[0049] In the present embodiment, the first snap-fit ​​seat 44 comprises a seat body 60 and first wedge blocks 61, which are formed integrally on both sides of the seat body 60, and a second wedge block 62 is provided accordingly on the limiting section 15 (as in Fig. (Figure 7). When the first snap seat 44 is engaged in the first slide 40, i.e., when the first wedge block 61 presses against the busbar 10, the power transmission mechanism 30 is fixed relative to the busbar 10 by the wedge-shaped interlocking of the first wedge block 61 and the second wedge block 62. This method is simple and easy to use. When the power transmission mechanism 30 requires maintenance, a force directed away from the busbar 10 is applied to the seat body 60, which allows the first wedge block 61 and the second wedge block 62 to be separated.

[0050] In some embodiments, in combination with Fig. 9, the power supply mechanism 20 comprises a power supply line 70, a second power pickup socket component 71 and a plug section 72, the second power pickup socket component 71 is detachably mounted on the power busbar 10 and connected to one end of the power supply line 70; the plug section 72 is connected to the other end of the power supply line 70, the plug section 72 is configured to allow connection to the power supply device, in some embodiments the power supply device may be one or a combination of several such devices, such as a constant voltage source, a power supply unit, a battery or other power supply devices capable of supplying electrical energy to the power supply mechanism 20, and the present application does not restrict this.
