Description

Technical Field

[0001] The present application relates to the technical field of sockets, and in particular to a power track and a concealed track socket. Background Art

[0002] The track socket is an innovative power socket. The track socket includes a power track and an adapter. The power track is usually installed on the wall and connected to the grid. The adapter is detachably connected to the power track and can draw power from the power track.

[0003] Track sockets include concealed track sockets and surface track sockets. Concealed track sockets can be installed in the concealed bottom box pre-buried in home decoration. After installation, its outer surface is basically flush with the wall or slightly protrudes from the wall. Surface track sockets can be directly hung on the wall. After installation, its outer surface protrudes from the wall. Concealed track sockets are widely used because their power tracks are hidden in the wall and can be hidden when not in use to keep the space clean and beautiful.

[0004] However, the power track assembly efficiency of the concealed track socket in the related art is not high, which affects the promotion of the concealed track socket. Utility Model Content

[0005] In view of the above problems, the embodiments of the present application provide a power track and a concealed track socket, which can improve the assembly efficiency of the power track.

[0006] In a first aspect, the present application provides an electric track for use in a concealed track socket. The electric track includes a one-piece base, a pressure plate, and a guide rail assembly. The one-piece base is connected to the pressure plate, and an installation cavity is formed between the one-piece base and the pressure plate. The installation cavity includes a cavity bottom, and a limiting structure is provided in the installation cavity. The guide rail assembly is installed in the installation cavity along a direction from the pressure plate to the cavity bottom, and is fixed in the installation cavity by the limiting structure.

[0007] Through the above scheme, the guide rail assembly is installed in the installation cavity along the direction from the pressure plate to the bottom of the cavity, and the installation direction is consistent with the insertion direction of the adapter. In other words, the guide rail assembly can be installed along the insertion direction of the adapter, and is not installed along the extension direction of the one-piece base of the long strip profile as in the prior art. In this way, it is possible to save the highly demanding and complex alignment procedures when installing the guide rail assembly and the one-piece base, thereby simplifying the difficulty of installing the guide rail assembly. In addition, a limiting structure is provided in the installation cavity, and the guide rail assembly can be fixed in the installation cavity by the limiting structure when being installed in the installation cavity. In this way, while simplifying the difficulty of installing the guide rail assembly, it will not affect the fixation of the guide rail assembly in the installation cavity, which facilitates improving the overall assembly efficiency of the power track, thereby facilitating the promotion of the application of concealed track sockets.

[0008] In one possible design, the guide rail assembly includes a positive guide rail and a negative guide rail, and the limiting structure includes at least two first limiting grooves and two second limiting grooves arranged at the bottom of the cavity. The arrangement direction of the two first limiting grooves is consistent with the extension direction of the positive guide rail, and the positive guide rail is at least partially located in the two first limiting grooves. The first limiting groove is used to limit the positive guide rail in the first direction, and the first direction is perpendicular to the extension direction of the positive guide rail and perpendicular to the direction from the pressure plate to the bottom of the cavity. The arrangement direction of the two second limiting grooves is consistent with the extension direction of the negative guide rail, and the negative guide rail is at least partially located in the two second limiting grooves. The second limiting groove is used to limit the negative guide rail in the first direction.

[0009] By providing at least two first limiting grooves arranged along the extension direction of the positive electrode rail at the bottom of the installation cavity, when the two first limiting grooves are spaced apart from each other and the positive electrode rail is at least partially located in the first limiting grooves, the two first limiting grooves can support the positive electrode rail at different positions in the extension direction of the positive electrode rail. In addition, the first limiting groove can limit the positive electrode rail in the first direction, reduce the possibility of the positive electrode rail shaking in the installation cavity along the first direction, and improve the stability of the positive electrode rail installed in the installation cavity. Similarly, when the two second limiting grooves are spaced apart from each other, the two second limiting grooves can support the negative electrode rail at different positions in the extension direction of the negative electrode rail, and can limit the negative electrode rail in the first direction, thereby improving the stability of the negative electrode rail installed in the installation cavity.

[0010] In a possible design, at least a first rib plate and a second rib plate are arranged at intervals at the bottom of the cavity. A first limiting groove is provided at a position where the first rib plate is opposite to the positive electrode rail, and a second limiting groove is provided at a position where the second rib plate is opposite to the positive electrode rail. A second limiting groove is provided at a position where the first rib plate is opposite to the negative electrode rail, and a second limiting groove is provided at a position where the second rib plate is opposite to the negative electrode rail.

[0011] Through the above scheme, the first limiting groove and the second limiting groove can cooperate to limit the position of the positive guide rail and the negative guide rail in the first direction, reducing the possibility of the positive guide rail and the negative guide rail shaking along the first direction in the installation cavity, and improving the stability of the installation of the positive guide rail and the negative guide rail in the installation cavity.

[0012] In a possible design, the limiting structure further includes a first protrusion, the first protrusion is arranged at the bottom of the first limiting groove, a first groove is arranged at a position where the positive rail is opposite to the first protrusion, the first protrusion extends into the first groove, and the first protrusion is used to limit the positive rail in the extension direction of the positive rail. And / or, the limiting structure further includes a second protrusion, the second protrusion is arranged at the bottom of the second limiting groove, a second groove is arranged at a position where the negative rail is opposite to the second protrusion, the second protrusion extends into the second groove, and the second protrusion is used to limit the negative rail in the extension direction of the negative rail.

[0013] Through the above scheme, the first protrusion cooperates with the first groove to limit the positive rail in the extension direction of the positive rail, reducing the possibility of the positive rail shaking in the extension direction of the positive rail, and improving the stability of the positive rail installed in the installation cavity. Similarly, the second protrusion cooperates with the second groove to limit the negative rail in the extension direction of the negative rail, reducing the possibility of the negative rail shaking in the extension direction of the negative rail, and improving the stability of the negative rail installed in the installation cavity.

[0014] In a possible design, the limiting structure further includes a pressing column, which is arranged on a side of the pressure plate facing the guide rail assembly, and the pressing column presses against the positive electrode rail and the negative electrode rail.

[0015] Through the above scheme, when the pressure plate is connected to the integrated base, the pressure plate will apply a resisting force to the positive rail and the negative rail to limit the possibility of the positive rail and the negative rail shaking in the direction from the pressure plate to the bottom of the cavity, thereby improving the stability of the positive rail and the negative rail in the installation cavity.

[0016] In a possible design, the guide rail assembly further includes a ground rail, and the limiting structure further includes a third limiting groove. The position where the first rib plate is opposite to the ground rail, and the position where the second rib plate is opposite to the ground rail, are both provided with the third limiting groove, and the third limiting groove is used to limit the ground rail in the first direction.

[0017] Through the above scheme, the third limiting groove can limit the position of the ground rail in the first direction, reduce the possibility of the ground rail shaking along the first direction in the installation cavity, and improve the stability of the ground rail installed in the installation cavity.

[0018] In a possible design, the limiting structure also includes a third protrusion, which is arranged at the bottom of the third limiting groove, and a third groove is provided at a position opposite to the ground guide rail and the third protrusion, and the third protrusion extends into the third groove, and the third protrusion is used to limit the ground guide rail in the extension direction of the ground guide rail.

[0019] Through the above scheme, a third protrusion is set at the bottom of the third limiting groove, and a third groove is set at the ground guide rail. The third protrusion cooperates with the third groove to limit the ground guide rail in the extension direction of the ground guide rail, thereby reducing the possibility of shaking of the ground guide rail in the extension direction of the ground guide rail and improving the stability of the ground guide rail installed in the installation cavity.

[0020] In a possible design, the limiting structure further includes a buckle, which is arranged on the groove wall of the third limiting groove in the first direction. At least one side of the ground rail in the first direction is engaged with the buckle, and the buckle is used to limit the ground rail in the direction from the pressure plate to the cavity bottom.

[0021] According to the above solution, when the ground rail is installed in the installation cavity along the direction from the pressure plate to the cavity bottom, at least one side of the ground rail in the first direction can be engaged with the buckle. In this way, the buckle can limit the ground rail from moving in the direction close to the pressure plate in the installation cavity, reduce the possibility of the ground rail shaking in the direction from the pressure plate to the cavity bottom, and improve the stability of the ground rail installed in the installation cavity.

[0022] In a possible design, the power rail further includes a panel, which covers the integrated base, and a side of the panel facing the guide rail assembly is pressed against a side of the pressure plate facing away from the guide rail assembly.

[0023] The side of the panel facing the rail assembly is pressed against the side of the pressure plate facing away from the rail assembly, and a pressing force can be applied to the side of the pressure plate facing away from the rail assembly to fix the position of the pressure plate relative to the panel and the integrated base. When the position of the pressure plate is fixed, the pressure plate is pressed against the side of the positive and negative rails facing away from the cavity bottom, and the position of the positive and negative rails relative to the pressure plate and the integrated base can be fixed, which is convenient for improving the stability of the installation of the positive and negative rails in the installation cavity.

[0024] In a second aspect, the present application provides a concealed track socket, comprising an adapter and the power track in the first aspect, wherein the adapter is mounted on the power track and electrically connected to the power track.

[0053] Figure 1 A schematic diagram of a combined structure of a power rail provided in an embodiment of the present application at a first viewing angle is shown in FIG. Figure 1 As shown, the concealed track socket includes an adapter (not shown) and a power track 100. The adapter is mounted on the power track 100 and is electrically connected to the power track 100.

[0054] The adapter is used to provide a plug-in position for a two-pin plug, a three-pin plug, a USB plug, etc., so the adapter may be provided with two sockets, three sockets, a USB interface, etc. The adapter of the present application includes but is not limited to an adapter with two sockets, an adapter with three sockets, or an adapter with a USB interface. Regardless of which adapter the adapter in the present application is, it can be electrically connected to the power rail 100.

[0055] The adapter is equipped with a positive conductive part, a negative conductive part and a ground conductive part, which can also be called an L-pole socket, an N-pole socket and an E-pole socket, respectively.

[0056] Figure 2 An exploded diagram of a power rail provided in an embodiment of the present application, such as Figure 2As shown, a positive rail 410, a negative rail 420 and a ground rail 430 are installed in the power rail 100, and the above rails can also be respectively referred to as an L-pole contact sheet, an N-pole contact sheet and an E-pole contact sheet. Among them, the positive conductive member corresponds to the positive rail 410, the negative conductive member corresponds to the negative rail 420, and the ground conductive member corresponds to the ground rail 430.

[0057] The power rail 100 is provided with a socket 101. After the adapter is inserted into the power rail 100 through the socket 101, the ground conductor is always electrically connected to the ground rail 430. When the positive conductor is in contact with the positive rail 410 to achieve electrical connection, and the negative conductor is in contact with the negative rail 420 to achieve electrical connection, the adapter can draw power from the power rail 100. On the contrary, when the positive conductor is not in contact with the positive rail 410, and the negative conductor is not in contact with the negative rail 420, the adapter cannot draw power from the power rail 100.

[0058] In the case where the adapter can draw power from the power rail 100 , the adapter can supply power to the electrical appliance by inserting a plug of the electrical appliance into the adapter.

[0059] The structure of the power rail 100 will be described in detail below with reference to the accompanying drawings.

[0060] The power track 100 provided in the embodiment of the present application is applied to a concealed track socket, such as Figure 2 As shown, the power rail 100 includes a conjoined base 200, a pressing plate 300 and a guide rail assembly 400. The conjoined base 200 is connected to the pressing plate 300, and an installation cavity 230 is formed between the conjoined base 200 and the pressing plate 300. The installation cavity 230 includes a cavity bottom 231, and a limiting structure 232 is provided in the installation cavity 230. The guide rail assembly 400 is installed in the installation cavity 230 along the direction from the pressing plate 300 to the cavity bottom 231, and is fixed in the installation cavity 230 by the limiting structure 232.

[0061] The one-piece base 200 may be roughly in a cubic structure, which is different from the long strip profile structure of the prior art. The one-piece base 200 is partially hollowed out, and the one-piece base 200 has only one side open, and the pressing plate 300 is connected to the open side. After the pressing plate 300 is connected to the one-piece base 200, an installation cavity 230 may be formed between the pressing plate 300 and the one-piece base 200.

[0062] The pressing plate 300 may be connected to the open side of the integrated base 200 by interference fit, snap connection or screw connection. The pressing plate 300 may be provided with an opening, and the shape and size of the opening may be set according to the shape and size of the end of the adapter for inserting into the power rail 100, so that the end of the adapter can extend into the installation cavity 230 through the opening.

[0063] The size of the installation cavity 230 is substantially equal to the size of the hollowed-out portion. The installation cavity 230 may be a circular cavity, a square cavity, or a special-shaped cavity, etc., and the embodiment of the present application does not limit the shape of the installation cavity 230. The cavity bottom 231 of the installation cavity 230 is the cavity wall of the installation cavity 230 away from the pressure plate 300. In the present application, the direction from the pressure plate 300 to the cavity bottom 231 is consistent with the direction in which the adapter is inserted into the power rail 100.

[0064] The inner wall of the integrated base 200 and the side of the pressure plate 300 facing the guide rail assembly 400 are both components of the cavity wall of the installation cavity 230. Therefore, the limiting structure 232 set in the installation cavity 230 can be set not only on the inner wall of the integrated base 200, but also on the side of the pressure plate 300 facing the guide rail assembly 400.

[0065] The rail assembly 400 is a conductive component in the power rail 100. The rail assembly 400 at least includes the aforementioned positive rail 410 and negative rail 420. In some power rails 100 with grounding requirements, the aforementioned ground rail 430 is also provided.

[0066] In the embodiment of the present application, the guide rail assembly 400 is installed in the installation cavity 230 along the direction from the pressure plate 300 to the cavity bottom 231, and the installation direction is consistent with the insertion direction OX of the adapter. In other words, the guide rail assembly 400 can be installed along the insertion direction OX of the adapter, and is not installed along the extension direction of the one-piece base 200 of the long profile as in the prior art. In this way, the highly demanding and complex alignment process of the guide rail assembly 400 and the one-piece base 200 can be saved, simplifying the installation difficulty of the guide rail assembly 400.

[0067] In addition, a limiting structure 232 is provided in the installation cavity 230, and when the guide rail assembly 400 is installed in the installation cavity 230, it can be fixed in the installation cavity 230 by the limiting structure 232. In this way, the fixing of the guide rail assembly 400 in the installation cavity 230 is not affected while simplifying the installation difficulty of the guide rail assembly 400, which is convenient for improving the overall assembly efficiency of the power track 100, thereby facilitating the promotion of the application of concealed track sockets.

[0068] Based on the aforementioned description that the guide rail assembly 400 includes a positive guide rail 410 and a negative guide rail 420, with respect to the limiting of the positive guide rail 410 and the negative guide rail 420 in the mounting cavity 230, the embodiment of the present application will exemplarily describe the limiting structure 232 of the guide rail assembly 400 from three mutually perpendicular directions in three-dimensional space.

[0069] The limiting structure 232 for limiting the positive electrode rail 410 and the negative electrode rail 420 in the first direction OZ in a three-dimensional space is described below.

[0070] Figure 3This is a schematic diagram of the structure of a one-piece base provided in an embodiment of the present application. Figure 4 A schematic diagram of a structure in which a guide rail assembly is installed on a one-piece base provided in an embodiment of the present application. In some possible designs, such as Figure 3 and Figure 4 As shown, the limiting structure 232 may include at least two first limiting grooves 240 and two second limiting grooves 250 provided on the cavity bottom 231. The arrangement direction of the two first limiting grooves 240 is consistent with the extension direction OY of the positive electrode rail, and the positive electrode rail 410 is at least partially located in the two first limiting grooves 240. The first limiting groove 240 is used to limit the positive electrode rail 410 in the first direction OZ. The arrangement direction of the two second limiting grooves 250 is consistent with the extension direction of the negative electrode rail 420. The negative electrode rail 420 is at least partially located in the two second limiting grooves 250. The second limiting grooves 250 are used to limit the negative electrode rail 420 in the first direction OZ.

[0071] The first direction OZ is perpendicular to the extension direction OY of the positive electrode rail, and is perpendicular to the direction from the pressing plate 300 to the cavity bottom 231 .

[0072] Generally, the positive rail 410 and the negative rail 420 are long strip structures, based on which, the extension direction OY of the positive rail refers to the length direction of the positive rail 410, and the extension direction of the negative rail 420 refers to the length direction of the negative rail 420. The first direction OZ is equivalent to the width direction of the positive rail 410 or the width direction of the negative rail 420.

[0073] The two first limiting grooves 240 are arranged at intervals along the extension direction OY of the positive electrode rail, and the size of the two first limiting grooves 240 in the first direction OZ may be slightly larger than the width of the positive electrode rail 410. In this way, the positive electrode rail 410 may be at least partially located in the two first limiting grooves 240, and the two sides of the positive electrode rail 410 in the first direction OZ may just contact the two groove walls of the first limiting grooves 240 in the first direction OZ, so that the first limiting grooves 240 may limit the positive electrode rail 410 in the first direction OZ.

[0074] Similarly, the two second limiting grooves 250 are arranged at intervals along the extension direction of the negative electrode rail 420, and the size of the two second limiting grooves 250 in the first direction OZ can be slightly larger than the width of the negative electrode rail 420. In this way, the negative electrode rail 420 can be at least partially located in the two second limiting grooves 250, and the two sides of the negative electrode rail 420 in the first direction OZ can just contact the two groove walls of the second limiting groove 250 in the first direction OZ, so that the second limiting groove 250 can limit the negative electrode rail 420 in the first direction OZ.

[0075] When the extension direction OY of the positive electrode rail is the same as the extension direction of the negative electrode rail 420, the arrangement direction of the two first limiting grooves 240 is also the same as the arrangement direction of the two second limiting grooves 250. In practice, the extension direction OY of the positive electrode rail may be the same as the extension direction of the negative electrode rail 420, or may have a slightly non-zero angle, which is not limited in the embodiment of the present application.

[0076] In summary, by providing at least two first limiting grooves 240 arranged along the extension direction OY of the positive electrode rail on the cavity bottom 231 of the installation cavity 230, when the two first limiting grooves 240 are spaced apart from each other and the positive electrode rail 410 is at least partially located in the first limiting grooves 240, the two first limiting grooves 240 can support the positive electrode rail 410 at different positions along the extension direction OY of the positive electrode rail. In addition, the first limiting grooves 240 can limit the positive electrode rail 410 in the first direction OZ, reduce the possibility of the positive electrode rail 410 shaking along the first direction OZ in the installation cavity 230, and improve the stability of the positive electrode rail 410 installed in the installation cavity 230. Similarly, when the two second limiting grooves 250 are spaced apart from each other, the two second limiting grooves 250 can support the negative electrode rail 420 at different positions in the extension direction of the negative electrode rail 420, and can limit the negative electrode rail 420 in the first direction OZ, thereby improving the stability of the negative electrode rail 420 installed in the installation cavity 230.

[0077] Regarding the arrangement of the first limiting groove 240 and the second limiting groove 250, as shown in FIG. Figure 3 and Figure 4 As shown, the cavity bottom 231 is at least spaced apart with a first rib plate 210 and a second rib plate 220, and the first limiting groove 240 and the second limiting groove 250 can be provided on the first rib plate 210 and the second rib plate 220. The number of the first limiting groove 240 and the number of the second limiting groove 250 can be two, three, etc. Figure 3 and Figure 4 The structure only shows that the number of ribs is three and the number of upper limit grooves on each rib is three, but this does not constitute a limitation on the technical solution of the present application.

[0078] In some possible designs, combining Figures 2 to 4 The extension direction of the first rib 210 is substantially perpendicular to the extension direction OY of the positive electrode rail, and the extension direction of the second rib 220 is substantially perpendicular to the extension direction of the negative electrode rail 420 .

[0079] In this case, the first rib plate 210 and the positive electrode rail 410 are opposite to each other, and the second rib plate 220 and the positive electrode rail 410 are opposite to each other, and the first limiting groove 240 is provided. The first rib plate 210 and the negative electrode rail 420 are opposite to each other, and the second rib plate 220 and the negative electrode rail 420 are opposite to each other, and the second limiting groove 250 is provided.

[0080] In this arrangement, the first limiting groove 240 and the second limiting groove 250 can cooperate to limit the position of the positive guide rail 410 and the negative guide rail 420 in the first direction OZ, thereby reducing the possibility of the positive guide rail 410 and the negative guide rail 420 shaking along the first direction OZ in the installation cavity 230, and improving the stability of the positive guide rail 410 and the negative guide rail 420 installed in the installation cavity 230.

[0081] In some other possible designs, the extension direction of the first rib 210 is consistent with the extension direction OY of the positive electrode rail, and the extension direction of the second rib 220 is consistent with the extension direction of the negative electrode rail 420 .

[0082] In this case, the first rib plate 210 is provided with a first limiting groove 240, the positive electrode guide rail 410 is at least partially located in the first limiting groove 240, and the two groove walls of the first limiting groove 240 in the first direction OZ limit the positive electrode guide rail 410. The second rib plate 220 is provided with a second limiting groove 250, the negative electrode guide rail 420 is at least partially located in the second limiting groove 250, and the two groove walls of the second limiting groove 250 in the first direction OZ limit the negative electrode guide rail 420.

[0083] In this way, the first limiting groove 240 limits the position of the positive guide rail 410 in the first direction OZ, and the second limiting groove 250 limits the position of the negative guide rail 420 in the first direction OZ. This can also reduce the possibility of the positive guide rail 410 and the negative guide rail 420 shaking along the first direction OZ in the installation cavity 230, thereby improving the stability of the positive guide rail 410 and the negative guide rail 420 installed in the installation cavity 230.

[0084] The limiting structure 232 for limiting the positive electrode rail 410 and the negative electrode rail 420 in the extension direction OY of the positive electrode rail and the extension direction of the negative electrode rail 420 in three-dimensional space is described below.

[0085] Figure 5 for Figure 3 The enlarged view of part A in the figure. Figure 6 A schematic diagram of the structure of a guide rail assembly provided in an embodiment of the present application, combined with Figures 2 to 6, the limiting structure 232 may further include a first protrusion 241. The first protrusion 241 is provided at the bottom of the first limiting groove 240, and a first groove 411 is provided at a position where the positive rail 410 is opposite to the first protrusion 241, and the first protrusion 241 extends into the first groove 411, and the first protrusion 241 is used to limit the positive rail 410 in the extension direction OY of the positive rail. And / or, the limiting structure 232 may further include a second protrusion 251. The second protrusion 251 is provided at the bottom of the second limiting groove 250, and a second groove 421 is provided at a position where the negative rail 420 is opposite to the second protrusion 251, and the second protrusion 251 extends into the second groove 421, and the second protrusion 251 is used to limit the negative rail 420 in the extension direction of the negative rail 420.

[0086] The first protrusion 241 may be in a cubic shape, a column shape, etc. The first groove 411 may be a blind groove or a through groove provided by the positive rail 410 in the direction from the pressing plate 300 to the cavity bottom 231. When the positive rail 410 is installed in the installation cavity 230 in the direction from the pressing plate 300 to the cavity bottom 231, the first protrusion 241 may be extended into the first groove 411.

[0087] The size of the first groove 411 in the extension direction OY of the positive electrode rail can be slightly larger than the size of the first protrusion 241 in the extension direction OY of the positive electrode rail, so that when the first protrusion 241 extends into the first groove 411, the two groove walls of the first groove 411 in the extension direction OY of the positive electrode rail can contact the two side walls of the first protrusion 241 in the extension direction OY of the positive electrode rail, so that the first protrusion 241 can limit the positive electrode rail 410 in the extension direction OY of the positive electrode rail.

[0088] The structure of the second protrusion 251 is similar to that of the first protrusion 241 , the structure of the second groove 421 is similar to that of the first groove 411 , and the function of the second protrusion 251 is similar to that of the first protrusion 241 , and the second protrusion 251 and the second groove 421 are not described in detail here.

[0089] Through the above scheme, the first protrusion 241 is provided at the bottom of the first limiting groove 240, and the first groove 411 is provided on the positive electrode rail 410. The first protrusion 241 cooperates with the first groove 411 to limit the positive electrode rail 410 in the extension direction OY of the positive electrode rail, thereby reducing the possibility of the positive electrode rail 410 shaking in the extension direction OY of the positive electrode rail, and improving the stability of the positive electrode rail 410 installed in the installation cavity 230. Similarly, the second protrusion 251 cooperates with the second groove 421 to limit the negative electrode rail 420 in the extension direction of the negative electrode rail 420, thereby reducing the possibility of the negative electrode rail 420 shaking in the extension direction of the negative electrode rail 420, and improving the stability of the negative electrode rail 420 installed in the installation cavity 230.

[0090] It should be noted that, in addition to the above-mentioned arrangement of the first protrusion 241 and the first groove 411, the first protrusion 241 can also be arranged on the positive electrode rail 410, and accordingly, the first groove 411 can be arranged at the bottom of the first limiting groove 240. Similarly, the second protrusion 251 can be arranged on the negative electrode rail 420, and accordingly, the second groove 421 can be arranged at the bottom of the second limiting groove 250. As long as the first protrusion 241 can limit the positive electrode rail 410 in the extension direction OY of the positive electrode rail through the cooperation with the first protrusion 241 and the first groove 411, and the second protrusion 251 can limit the negative electrode rail 420 in the extension direction of the negative electrode rail 420 through the cooperation with the second protrusion 251 and the second groove 421, the embodiment of the present application does not limit the arrangement positions of the first protrusion 241 and the first groove 411.

[0091] The limiting structure 232 for limiting the positive electrode rail 410 and the negative electrode rail 420 in the direction from the pressing plate 300 to the cavity bottom 231 in three-dimensional space is described below.

[0092] Figure 7 A schematic diagram of the structure of a pressure plate provided in an embodiment of the present application is shown in FIG. Figure 8 A schematic diagram of the structure of another power rail provided in an embodiment of the present application, Fig. 9 For along Figure 8 Cross-sectional view of the BB section in some possible designs, combined with Figure 2 , Figures 7 to 9 The limiting structure 232 may further include a pressing column 310 , which is disposed on a side of the pressure plate 300 facing the guide rail assembly 400 , and the pressing column 310 presses against the positive electrode rail 410 and the negative electrode rail 420 .

[0093] The pressing column 310 is equivalent to a convex rib provided by the pressing plate 300 toward the guide rail assembly 400. The pressing column 310 can be in any shape such as a cylindrical shape or a prism shape.

[0094] The positive rail 410 and the negative rail 420 are installed in the installation cavity 230 near the pressing plate 300. A pressing column 310 may be provided at a position of the pressing plate 300 facing the positive rail 410 and opposite to the positive rail 410, so as to press the positive rail 410 through the pressing column 310 there. A pressing column 310 may also be provided at a position of the pressing plate 300 facing the negative rail 420 and opposite to the negative rail 420, so as to press the negative rail 420 through the pressing column 310 there.

[0095] After the guide rail assembly 400 is installed in the installation cavity 230 along the direction from the pressing plate 300 to the cavity bottom 231, the pressing plate 300 is connected to the integrated base 200 along the same direction. Since the pressing plate 300 is provided with a pressing column 310 on the side facing the guide rail assembly 400, when the pressing plate 300 is connected to the integrated base 200, the pressing column 310 can press against the side of the positive electrode guide rail 410 and the negative electrode guide rail 420 facing away from the cavity bottom 231.

[0096] like Figure 2 , Figure 3 and Fig. 9 As shown, the positive rail 410 and the negative rail 420 are supported on the first rib plate 210 and the second rib plate 220 on the side facing the cavity bottom 231, and the positive rail 410 and the negative rail 420 are in contact with the pressing column 310 on the side facing away from the cavity bottom 231. In this way, when the pressing plate 300 is connected to the integrated base 200, the pressing plate 300 will apply a pressing force to the positive rail 410 and the negative rail 420 to limit the possibility of the positive rail 410 and the negative rail 420 shaking in the direction from the pressing plate 300 to the cavity bottom 231, thereby improving the stability of the positive rail 410 and the negative rail 420 installed in the installation cavity 230.

[0097] Based on the above description, the guide rail assembly 400 may also include a ground rail 430. Regarding the positioning of the ground rail 430 in the installation cavity 230, the embodiment of the present application will also exemplarily describe the positioning structure 232 of the ground rail 430 from three mutually perpendicular directions in three-dimensional space.

[0098] The limiting structure 232 for limiting the ground rail 430 in the first direction OZ in three-dimensional space is described below.

[0099] Please continue to refer to Figures 2 to 6 The limiting structure 232 may further include a third limiting groove 260. The position where the first rib plate 210 is opposite to the ground rail 430 and the position where the second rib plate 220 is opposite to the ground rail 430 are both provided with a third limiting groove 260, and the third limiting groove 260 is used to limit the ground rail 430 in the first direction OZ.

[0100] Like the positive rail 410 and the negative rail 420, the ground rail 430 is also usually a long strip structure, based on which, the extension direction of the ground rail 430 refers to the length direction of the ground rail 430. The first direction OZ is also equivalent to the width direction of the ground rail 430.

[0101] The two third limiting grooves 260 are arranged at intervals along the extension direction of the ground rail 430, and the size of the two third limiting grooves 260 in the first direction OZ may be slightly larger than the width of the ground rail 430. In this way, the ground rail 430 may be at least partially located in the two third limiting grooves 260, and the two sides of the ground rail 430 in the first direction OZ may just contact the two groove walls of the third limiting grooves 260 in the first direction OZ, so that the third limiting grooves 260 can limit the ground rail 430 in the first direction OZ.

[0102] Through the above scheme, the third limiting groove 260 can limit the position of the ground guide rail 430 in the first direction OZ, reducing the possibility of the ground guide rail 430 shaking along the first direction OZ in the installation cavity 230, and improving the stability of the ground guide rail 430 installed in the installation cavity 230.

[0103] The limiting structure 232 for limiting the earth pole guide rail 430 in the extension direction of the earth pole guide rail 430 in three-dimensional space is described below.

[0104] Please continue to refer to Figure 5 and Figure 6 In some possible designs, the limiting structure 232 may further include a third protrusion 261, which is disposed at the bottom of the third limiting groove 260, and a third groove 431 is disposed at a position where the ground guide rail 430 is opposite to the third protrusion 261, and the third protrusion 261 extends into the third groove 431, and the third protrusion 261 is used to limit the ground guide rail 430 in the extension direction of the ground guide rail 430.

[0105] The structure of the third protrusion 261 is similar to that of the first protrusion 241 , the structure of the third groove 431 is similar to that of the first groove 411 , and the function of the third protrusion 261 is similar to that of the first protrusion 241 , and the third protrusion 261 and the third groove 431 are not described in detail here.

[0106] Through the above scheme, the third protrusion 261 is set at the bottom of the third limiting groove 260, and the third groove 431 is set on the ground guide rail 430. The third protrusion 261 cooperates with the third groove 431 to limit the ground guide rail 430 in the extension direction of the ground guide rail 430, thereby reducing the possibility of shaking of the ground guide rail 430 in the extension direction of the ground guide rail 430 and improving the stability of the ground guide rail 430 installed in the installation cavity 230.

[0107] It should be noted that, in addition to being arranged in the above-mentioned manner, the third protrusion 261 and the third groove 431 may also be arranged on the ground rail 430, and correspondingly, the third groove 431 may be arranged at the bottom of the third limiting groove 260. As long as the third protrusion 261 can limit the ground rail 430 in the extension direction of the ground rail 430 through the cooperation between the third protrusion 261 and the third groove 431, the embodiment of the present application does not limit the arrangement positions of the third protrusion 261 and the third groove 431.

[0108] The limiting structure 232 for limiting the ground rail 430 in the direction from the pressing plate 300 to the cavity bottom 231 in three-dimensional space is described below.

[0109] Fig.10 for Figure 4 The enlarged view of part C in the middle, combined with Figure 3 , Figure 4 and Fig.10 In some possible designs, the limiting structure 232 may further include a buckle 262, which is disposed on the groove wall of the third limiting groove 260 in the first direction OZ. At least one side of the ground rail 430 in the first direction OZ is engaged with the buckle 262, and the buckle 262 is used to limit the ground rail 430 in the direction from the pressing plate 300 to the cavity bottom 231.

[0110] The number of the buckle 262 can be one, and the buckle 262 can be arranged on any one of the groove walls of the third limiting groove 260 in the first direction OZ. The number of the buckle 262 can also be two, and one of the two buckles 262 can be arranged on one groove wall of the third limiting groove 260 in the first direction OZ, and the other of the two buckles 262 can be arranged on the other groove wall of the third limiting groove 260 in the first direction OZ.

[0111] like Fig.10 As shown, the two sides of the ground rail 430 in the first direction OZ may respectively include a small plane, and the ground rail 430 may be engaged with the buckle 262 through the small plane.

[0112] A buckle 262 is provided on the groove wall of the third limiting groove 260 in the first direction OZ, and when the ground rail 430 is installed in the installation cavity 230 along the direction from the pressing plate 300 to the cavity bottom 231, at least one side of the ground rail 430 in the first direction OZ can be engaged with the buckle 262. In this way, the buckle 262 can limit the ground rail 430 from moving in the direction close to the pressing plate 300 in the installation cavity 230, reduce the possibility of the ground rail 430 shaking in the direction from the pressing plate 300 to the cavity bottom 231, and improve the stability of the ground rail 430 installed in the installation cavity 230.

[0113] Fig.11 A schematic diagram of the structure of a panel provided in an embodiment of the present application, in some possible designs, such as Figure 2 and Fig.11 As shown, the power rail 100 may further include a panel 500 , which covers the integrated base 200 , and the panel 500 faces a side of the guide rail assembly 400 and presses against a side of the pressure plate 300 facing away from the guide rail assembly 400 .

[0114] One of the panel 500 and the integrated base 200 may be provided with a buckle structure 510, and the other of the panel 500 and the integrated base 200 may be provided with a groove structure. The buckle structure 510 and the groove structure may be buckled together to realize the connection between the panel 500 and the integrated base 200. Fig.11 The buckle structure 510 shown in the figure is arranged on the panel 500, but this does not constitute a limitation on the technical solution of the present application.

[0115] Combination Figure 2 and Fig.11 A plurality of ribs 512 may be provided on the side of the panel 500 facing the guide rail assembly 400. After the panel 500 is covered with the integrated base 200, the plurality of ribs 512 may be pressed against the side of the pressure plate 300 facing away from the guide rail assembly 400, so as to realize the pressing of the pressure plate 300 by the side of the panel 500 facing the guide rail assembly 400.

[0116] The side of the panel 500 facing the rail assembly 400 is pressed against the side of the pressing plate 300 facing away from the rail assembly 400, and a pressing force can be applied to the side of the pressing plate 300 facing away from the rail assembly 400 to fix the position of the pressing plate 300 relative to the panel 500 and the integrated base 200. When the position of the pressing plate 300 is fixed, the pressing plate 300 is pressed against the side of the positive electrode rail 410 and the negative electrode rail 420 facing away from the cavity bottom 231, and the position of the positive electrode rail 410 and the negative electrode rail 420 relative to the pressing plate 300 and the integrated base 200 can be fixed, so as to improve the stability of the positive electrode rail 410 and the negative electrode rail 420 installed in the installation cavity 230.

[0117] Please continue to refer to Figure 2 In some possible designs, the power rail 100 may further include a dustproof member 600, which is installed on the side of the pressure plate 300 facing away from the guide rail assembly 400. The dustproof member 600 can allow the end of the adapter to pass through so that the end of the adapter extends into the installation cavity 230 and is electrically connected to the guide rail assembly 400.

[0118] Please continue to refer to Figure 6In some possible designs, in the power rail 100 of the present application, the positive rail 410 is directly assembled with the positive terminal 700, the negative rail 420 is directly assembled with the negative terminal 800, and the ground rail 430 is directly assembled with the ground terminal 900.

[0119] The external positive conductive member can be electrically connected to the positive rail 410 in the positive terminal 700 , the external negative conductive member can be electrically connected to the negative rail 420 in the negative terminal 800 , and the ground conductive member can be electrically connected to the ground rail 430 in the ground terminal 900 .

[0120] In the embodiment of the present application, the installation directions of the guide rail assembly 400, the pressing plate 300, the dustproof member 600 and the panel 500 are all the same as the insertion direction OX of the adapter. Figure 2 When assembling the power rail 100 of the present application, the guide rail assembly 400 can be first installed into a suitable position in the installation cavity 230 along the insertion direction OX of the adapter, and then the pressing plate 300 can be connected to the one-piece base 200 along the insertion direction OX of the adapter, and then the dustproof member 600 can be installed on the side of the pressing plate 300 facing away from the guide rail assembly 400 along the insertion direction OX of the adapter, and finally the panel 500 can be connected to the one-piece base 200 along the insertion direction OX of the adapter. In this way, the assembly process of the power rail 100 can be realized.

[0121] Compared with the prior art in which structural components such as the guide rail assembly 400, the pressure plate 300, the dustproof member 600 and the panel 500 are installed along the extension direction of the one-piece base 200 of the long profile, the present application installs structural components such as the guide rail assembly 400, the pressure plate 300, the dustproof member 600 and the panel 500 along the insertion direction OX of the adapter, which can save the highly demanding and complex alignment processes when installing the structural components such as the guide rail assembly 400, the pressure plate 300, the dustproof member 600 and the panel 500 with the one-piece base 200, thereby facilitating the improvement of the assembly efficiency of the power track 100.

[0122] In addition, compared with the prior art, the present application eliminates the insulating sheath and directly installs the guide rail assembly 400 and other structural parts in the integrated base 200, which saves the number of parts used and facilitates saving the cost of the power rail 100.
