Description

Technical Field

[0001] This invention relates to an electrical connection device and a track light assembly, belonging to the field of lighting equipment. Background Technology

[0002] Track lighting is a common type of lighting equipment on the market. It is fixed to a wall via a track, allowing the lighting fixtures to be moved and freely positioned at any point along the track, thus achieving diverse lighting effects. Where there are corners in the wall, the track may sometimes be installed from the ceiling onto a side wall. The track length is typically no more than 2 meters, requiring an electrical connection device to link the track.

[0003] However, the design of using electrical connectors to connect the track has several drawbacks. For example, the electrical connectors will occupy track space, thereby reducing the utilization rate of the lights. Also, when splicing corners, gaps will be exposed, and if the gaps are to be filled, additional parts are required, making the actual installation very troublesome. Furthermore, the electrical connectors protrude outside the track, which also greatly affects the appearance.

[0004] In view of this, it is indeed necessary to propose a new electrical connection device and track light assembly to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an electrical connection device and a track light assembly, which makes the electrical connection device simple in structure, easy to connect to the track, and does not protrude from the track after connection.

[0006] To achieve the above objectives, the present invention provides an electrical connection device for connecting a track, comprising a main body and a first connecting portion and a second connecting portion disposed at both ends of the main body and electrically connected thereto. The main body includes a base plate extending toward the first connecting portion and the second connecting portion and a plug-in assembly. The base plate is connected to the first connecting portion and the second connecting portion. The first connecting portion and the second connecting portion each include a first electrical contact portion and a second electrical contact portion disposed at a left-right interval. The plug-in assembly is suspended above the base plate and disposed between the first electrical contact portion and the second electrical contact portion. In a vertical cross-section, the plug-in assembly is triangularly arranged with the first electrical contact portion and the second electrical contact portion.

[0007] As a further improvement of the present invention, the plug-in assembly includes a first plug-in portion and two second plug-in portions arranged in a triangular shape. The two second plug-in portions extend in a vertical direction, are symmetrically arranged on both sides of the first plug-in portion, and are positioned lower than the first plug-in portion.

[0008] As a further improvement of the present invention, in the vertical direction, the cross-sectional areas of the first insertion portion and the second insertion portion gradually decrease from the end closer to the main body to the end farther away from the main body.

[0009] As a further improvement of the present invention, the length of the first plug portion is less than or equal to the length of the first connecting portion / second connecting portion, and greater than the length of the second plug portion.

[0010] As a further improvement of the present invention, both the first electrical contact portion and the second electrical contact portion include a first conductive spring and a second conductive spring. The two first conductive springs are respectively disposed on the side of the first electrical contact portion and the second electrical contact portion away from the substrate, and the two second conductive springs are disposed on the side of the first electrical contact portion and the second electrical contact portion facing the plug-in assembly, and are at least partially exposed outside the first electrical contact portion and the second electrical contact portion.

[0011] As a further improvement of the present invention, the electrical connection device further includes a cover, the cover including a receiving portion and wings extending from the receiving portion toward the first connection portion and the second connection portion respectively and covering the first connection portion and the second connection portion.

[0012] As a further improvement of the present invention, a third connecting part is provided inside the receiving part, and the first connecting part and the second connecting part are electrically connected through the third connecting part.

[0013] As a further improvement of the present invention, the wing is provided with an opening, and the first electrical contact and the second electrical contact are each provided with a first conductive spring, the first conductive spring being sandwiched between the wing and the first electrical contact, and at least partially exposed outside the opening.

[0014] As a further improvement of the present invention, the electrical connection device includes a planar straight electrical connection device, a planar corner electrical connection device, and a vertical corner electrical connection device.

[0015] The present invention also provides a track light assembly, including any of the above-described electrical connection devices and at least two tracks, wherein the at least two tracks are mechanically and electrically connected through the electrical connection devices.

[0016] The beneficial effects of this invention are as follows: The electrical connection device of this invention includes a first connecting portion, a second connecting portion, and a substrate and a plug-in assembly extending from the main body at both ends. Both the first and second connecting portions include symmetrically spaced first and second electrical contacts. The plug-in assembly is disposed between the first and second electrical contacts, and is arranged in a triangular shape in the vertical cross-section. Unlike existing electrical connection devices, this application divides the connection portion into a first electrical contact, a second electrical contact, and a plug-in assembly instead of integrating them together, thus reducing the thickness of the first connecting portion connected to the track and making it more flattened. Simultaneously, the first... The electrical contact part and the second electrical contact part are used for electrical connection with the track, and the plug-in assembly is used for mechanical connection with the track. While ensuring a stable and reliable connection, the structure of the electrical connection device is simplified. The installation process only requires plugging to complete the connection, which is convenient for installation. Moreover, all three parts are inserted into the track and do not protrude from the track, which is more aesthetically pleasing. At the same time, the spaced first electrical contact part and the second electrical contact part ensure the installation distance and reduce the possibility of short circuit. Furthermore, by setting a base plate, the interior of the track is blocked, which not only serves as a dustproof function but also serves as an aesthetic function. This solves the problems of complex structure, inconvenient connection with the track, and protrusion from the track in existing electrical connection devices. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1-4As shown, this invention discloses an electrical connection device 100 used for connecting tracks 201 of a track light assembly 200, comprising a main body 1, a first connecting portion 2, and a second connecting portion 3. The first connecting portion 2 and the second connecting portion 3 are located at both ends of the main body 1. In embodiments of this application, the first connecting portion 2 and the second connecting portion 3 have identical structures and are electrically connected, eliminating the need for differentiation during use and improving the versatility of the electrical connection device 100. In other embodiments of this application, the structures of the first connecting portion 2 and the second connecting portion 3 may be different. The main body 1 is used to connect the first connecting portion 2 and the second connecting portion 3. By inserting the first connecting portion 2 and the second connecting portion 3 into two identical or different tracks 201 respectively, two identical or different tracks 201 are mechanically connected and electrically linked.

[0040] The main body 1 includes a substrate 11 and a plug-in assembly 12, which extend toward the first connecting portion 2 and the second connecting portion 3. The portion extending toward the first connecting portion 2 is referred to as the first substrate 111 and the first plug-in assembly 121, and the portion extending toward the second connecting portion 3 is referred to as the second substrate 112 and the second plug-in assembly 122. In embodiments of this application, the first substrate 111 and the second substrate 112 have the same structure, and the first plug-in assembly 121 and the second plug-in assembly 122 have the same structure. In other embodiments of this application, the structures of the first substrate 111 and the second substrate 112, and the first plug-in assembly 121 and the second plug-in assembly 122 may also be different. The first connecting portion 2 and the second connecting portion 3 are respectively disposed on the first substrate 111 and the second substrate 112 and connected to the substrate 11. Simultaneously, the substrate 11 serves as a cover; after the first connecting portion 2 and the second connecting portion 3 are inserted into the track 201, the substrate 11 is not inserted into the track 201 but is located outside the track 201, concealing the internal structure of the track 201 for aesthetic purposes.

[0041] The first plug-in assembly 121 includes a first plug-in part 1211 and a second plug-in part 1212. The first plug-in assembly 121 is used to be inserted into the track 201 and to achieve a mechanical connection with the track 201.

[0042] The first insertion part 1211 is used to insert into the track 201. The first insertion part 1211 in the first insertion assembly 121 extends from the main body 1 towards the first connecting part 2, and the cross-sectional area in the vertical direction gradually decreases from the end closer to the main body 1 to the end farther away from the main body 1. As the track 201 is gradually inserted into the first connecting part 2 of the electrical connection device 100, the track 201 and the electrical connection device 100 gradually approach each other. Since the first insertion part 1211 is correspondingly arranged with the first groove 2011 of the track 201, as it gradually penetrates into the first groove 2011, the track 201 is inserted in the direction away from the main body 1 and closer to the main body 1. The cross-sectional area in the vertical direction of the first insertion part 1211 gradually increases with insertion until it is greater than the cross-sectional area of ​​the first groove 2011, thereby locking into the first groove 2011.

[0043] The second insertion portion 1212 is used to insert into the track 201. The second insertion portion 1212 in the first insertion assembly 121 extends from the main body 1 towards the first connecting portion 2, and the cross-sectional area in the vertical direction gradually decreases from the end closer to the main body 1 to the end farther away from the main body 1. At the same time, the vertical cross-section of the second insertion portion 1212 is rectangular, and the vertical direction is the length direction of the rectangle, that is, the second insertion portion 1212 also extends in the vertical direction. As the track 201 is gradually inserted into the first connecting part 2 of the electrical connecting device 100, the track 201 and the electrical connecting device 100 gradually approach each other. The second insertion part 1212 is correspondingly set with the second groove 2012 of the track 201, and as it is inserted, it gradually penetrates deeper into the second groove 2012. At this time, the track 201 is inserted in the direction away from the main body 1 and closer to the main body 1. The vertical cross-sectional area of ​​the second insertion part 1212 gradually increases as it is inserted, and the length of the rectangular cross-section, i.e., the vertical height, continuously increases, thereby locking into the second groove 2012.

[0044] The first insertion part 1211 and the second insertion part 1212, whose vertical cross-sectional area gradually decreases as the distance from the main body 1 increases, facilitate the initial alignment of the insertion position during the insertion process, and at the same time, can fully achieve fastening with the track 201 after the insertion is completed, ensuring the reliability of the mechanical connection.

[0045] The length of the first plug-in component 121 is less than or equal to the length of the first connecting portion 2 / second connecting portion 3. In the embodiments of this application, the length of the first plug-in component 121 is equal to the length of the first connecting portion 2 / second connecting portion 3, so that together with the first connecting portion 2 / second connecting portion 3, it can be fully inserted into the track 201 to ensure the reliability of the connection. Furthermore, the length of the first plug-in portion 1211 is greater than the length of the second plug-in portion 1212, with the first plug-in portion 1211 being the main plug-in portion and the second plug-in portion 1212 being the auxiliary plug-in portion.

[0046] In the embodiments of this application, the first plug-in assembly 121 includes a first plug-in portion 1211 and two second plug-in portions 1212, arranged in a triangle. This triangular arrangement of the first plug-in portion 1211 and the two second plug-in portions 1212 makes the mechanical connection with the track 201 more stable. The two second plug-in portions 1212 are located on both sides of the first plug-in portion 1211 and are positioned below the first plug-in portion 1211. The length of the second plug-in portions 1212 is less than the length of the first plug-in portion 1211. The vertical cross-section of the two second plug-in portions 1212 is rectangular, and the lengths of the long and short sides of the rectangle change with the distance from the main body 1. In the embodiments of this application, the lengths gradually decrease as the distance from the main body 1 increases. The long side of the rectangle is the vertical height in the cross-section. The value of the long side is a variable range, which includes the vertical height of the cross-section of the second groove 2012. The range of the distance between the farthest edges of the vertical cross-sections of the two second plug-in parts 1212 includes the vertical length of the second groove 2012. The two second plug-in parts 1212 are thus regarded as a whole, a stepped platform with the middle part removed but the two ends retained, so that the two second plug-in parts 1212 can be engaged with the second groove 2012 as they are gradually inserted.

[0047] The second plug-in component 122 has the same structure as the first plug-in component 121, but in the opposite direction, and will not be described in detail here.

[0048] The first connecting part 2 includes a first electrical contact 21 and a second electrical contact 22. The first connecting part 2 is used to insert into the rail 201 to realize the electrical connection between the electrical connection device 100 and the rail 201. The first electrical contact 21, the second electrical contact 22, and the plug-in assembly 12 are all inserted into the rail 201.

[0049] The first electrical contact 21 and the second electrical contact 22 are disposed on the substrate 11 extending from the main body 1. They are symmetrically arranged and spaced apart. The first electrical contact 21 and the second electrical contact 22 are used to insert into the track 201 and are electrically connected to the track 201. The insertion assembly 12 is disposed between the first electrical contact 21 and the second electrical contact 22. The insertion assembly 12 is connected to the main body 1 and extends along the main body 1 towards the first connecting part 2. It is suspended on the substrate 11. In the vertical cross-section, the insertion assembly 12, the first electrical contact 21 and the second electrical contact 22 form a triangle. The insertion assembly 12 is used to insert into the track 201 and achieve a mechanical connection with the track 201.

[0050] In the embodiments of this application, both the first electrical contact 21 and the second electrical contact 22 are cuboid in shape, each including a first conductive spring 211 and a second conductive spring 212. The two first conductive springs 211 are respectively disposed on the side of the first electrical contact 21 and the second electrical contact 22 away from the substrate 11, and the two second conductive springs 212 are each disposed on the side of the first electrical contact 21 and the second electrical contact 22 facing the insertion assembly 12, and are at least partially exposed outside the first electrical contact 21 and the second electrical contact 22. The first conductive spring 211 is used to contact the first copper sheet 2016 in the track 201 for electrical connection, and the second conductive spring 212 is used to contact the second copper sheet 2017 in the track 201 for electrical connection.

[0051] Specifically, taking the first electrical contact 21 as an example, a first conductive spring 211 is disposed on the side of the first electrical contact 21 facing away from the substrate 11, and the first electrical contact 21 is also provided with a receiving groove 213. The receiving groove 213 of the first electrical contact 21 of the first connecting portion 2 and the receiving groove 213 of the first electrical contact 21 of the second connecting portion 3 are connected, and a second conductive spring 212 is disposed in the receiving groove 213. In the embodiments of this application, the receiving groove 213 contains a wire for electrically connecting the two second conductive springs 212 between the first contact 21 of the first connecting portion 2 and the first contact 21 of the second connecting portion 3.

[0052] The first electrical contact 21 is also provided with a spring-loaded limiting platform 214, which is correspondingly arranged with the first conductive spring 211 and / or the second conductive spring 212 to limit the first conductive spring 211 and / or the second conductive spring 212, so that the first conductive spring 211 and / or the second conductive spring 212 protrude from the first electrical contact 21. After the first electrical contact 21 is inserted into the track 201, the elastic first conductive spring 211 and / or the second conductive spring 212 will deform under force, which may lead to poor contact. The spring-loaded limiting platform 214 is provided to ensure that the first conductive spring 211 always protrudes from the opening 421 and the second conductive spring 212 always protrudes from the hole 422, so as to ensure electrical connection with the first copper sheet 2016 and the second copper sheet 2017 of the track 201.

[0053] The structure of the second electrical contact 22 is symmetrical and the same as that of the first electrical contact 21. It also has a first conductive spring 211, a second conductive spring 212, a receiving groove 213, and a spring limiting platform 214, which will not be described in detail here.

[0054] The second connecting part 3 has the same structure as the first connecting part 2 and is located on the other end of the main body 1 opposite to the first connecting part 2. It also has a first electrical contact part 21 and a second electrical contact part 22, which will not be described in detail here.

[0055] The electrical connection device 100 also includes a cover 4, which includes a receiving portion 41 and wings 42 extending from the receiving portion 41 toward the first connecting portion 2 and the second connecting portion 3 respectively, and covering the first connecting portion 2 and the second connecting portion 3. The cover 4 is used to cooperate with the main body 1, covering the main body 1 from top to bottom or set on the left and right sides of the main body 1, thereby covering the main body 1, ensuring both aesthetics and safety.

[0056] A third connecting part 411 is provided inside the receiving part 41, and the first connecting part 2 and the second connecting part 3 are electrically connected through the third connecting part 411. In the embodiments of this application, the third connecting part 411 is a wire. Further, the first conductive spring 211 of the first electrical contact 21 of the first connecting part 2 and the first conductive spring 211 of the first electrical contact 21 of the second connecting part 3, the first conductive spring 211 of the second electrical contact 22 of the first connecting part 2 and the first conductive spring 211 of the second electrical contact 22 of the second connecting part 3 are electrically connected through the third connecting part 411.

[0057] The wing 42 is provided with an opening 421, and the opening 421 and the first conductive spring 211 are correspondingly provided. The first electrical contact 21 and the second electrical contact 22 are both provided with the first conductive spring 211. The first conductive spring 211 is sandwiched between the wing 42 and the first electrical contact 21, and is limited by the spring limiting platform 214, and is at least partially exposed outside the opening 421.

[0058] After the cover 4 is installed on the main body 1, a hole 422 is formed between the wing 42 and the first electrical contact 21 / second electrical contact 22. The hole 422 is positioned towards the plug-in assembly 12, and the second conductive spring 212, which is located in the receiving groove 213 of the first electrical contact 21, is limited by the spring limiting stage 214 and is at least partially exposed in the hole 422.

[0059] Please refer to the previous document. Figure 3 , Figure 4 , Figure 5 As shown, in one embodiment of this application, the electrical connection device 100 is a planar linear electrical connection device used to connect two tracks 201 located on the same straight line in the horizontal direction. In this case, the first connecting portion 2 and the second connecting portion 3 of the electrical connection device 100 are also located on the same straight line in the horizontal direction. The main body 1 includes a cover 4, which includes a first cover 43 and a second cover 44. The first cover 43 and the second cover 44 have symmetrical and identical structures. Both the first cover 43 and the second cover 44 are mounted on the main body 1 in a top-to-bottom direction.

[0060] Please see Figures 6-7As shown, in one embodiment of this application, the electrical connection device 101 is a planar corner electrical connection device, used to connect two tracks 201 arranged at an angle in the horizontal direction. At this time, the first connecting part 2 and the second connecting part 3 of the electrical connection device 100 are also arranged at the same angle in the horizontal direction. At this time, the main body 1 includes a cover 4, and the cover 4 includes a third cover 45, which is integrally formed and covers the main body 1 in a downward direction.

[0061] Please see Figures 8-9 As shown, in one embodiment of this application, the electrical connection device 102 is a facade corner electrical connection device, used to connect two tracks 201 within the facade space. That is, the two tracks 201 are not on the same horizontal plane, and the extension lines of the two tracks 201 on the three-dimensional facade form an angle. The first connecting part 2 and the second connecting part 3 of the electrical connection device 102 are also set at the same angle on the three-dimensional facade. The main body 1 includes a cover 4, which includes a fourth cover 46 and a fifth cover 47. The fourth cover 46 and the fifth cover 47 are symmetrically arranged and respectively installed on both sides of the main body 1.

[0062] Furthermore, in this application, the two first conductive springs 211 and the two second conductive springs 212 between the first connecting part 2 and the second connecting part 3 are connected by wires located in the receiving groove 213 and the receiving part 41. In another embodiment of this application, the two first conductive springs 211 and the wires between them are integrally formed, and the two second conductive springs 212 and the wires between them are also integrally formed, further simplifying the structure of the electrical connection device 100.

[0063] Please see Figures 10-11 As shown, this application also provides a track light assembly 200, including a track 201 and an electrical connection device 100. There are multiple tracks 201. In the embodiments of this application, there are at least two tracks 201. Any two tracks 201 are electrically connected by inserting the first connection part 2 and the second connection part 3 of the electrical connection device 100 into the two tracks 201 respectively. The mechanical connection is achieved by inserting the plug-in assembly 12 into the track 201.

[0064] In the embodiments of this application, from a vertical cross-section, the track 201 includes a first groove 2011 and a second groove 2012 located at the center and arranged sequentially from top to bottom. A third groove 2013 and a fourth groove 2014 with the same structure are symmetrically arranged on the left and right sides of the first groove 2011 and the second groove 2012.

[0065] The first groove 2011 is used to connect with the first plug-in part 1211 to achieve a mechanical connection between the track 201 and the electrical connection device 100. As the insertion depth of the first plug-in part 1211 increases, the vertical cross-sectional area of ​​the first plug-in part 1211 increases until it is greater than the vertical cross-sectional area of ​​the first groove 2011, thereby achieving a fixed connection between the electrical connection device 100 and the track 201.

[0066] The second slot 2012 is used to connect with the second plug-in part 1212 to achieve a mechanical connection between the track 201 and the electrical connection device 100. Two second plug-in parts 1212 are inserted into the second slot 2012, located on the left and right sides of the slot 2012 respectively. As the insertion depth of the second plug-in part 1212 increases, the vertical cross-sectional area of ​​the second plug-in part 1212 increases until the vertical height of the second plug-in part 1212 is greater than the vertical height of the second slot 2012, thus locking into the second slot 2012 and achieving a fixed connection between the electrical connection device 100 and the second slot 2012 of the track 201.

[0067] The third slot 2013 and the fourth slot 2014 are respectively used to connect with the first electrical contact 21 and the second electrical contact 22 to realize the electrical connection between the track 201 and the electrical connection device 100. Taking the third slot 2013 as an example, a conductive sheet mounting base 2015 is provided in the third slot 2013. By setting the conductive sheet mounting base 2015, the slot body of the third slot 2013, which originally had an irregular cross-section, is transformed into a slot body with the same vertical cross-sectional shape as the first electrical contact 21. In this application, the first electrical contact 21 is cuboid in shape, and its vertical cross-section is also rectangular. The vertical cross-section of the third slot 2013 with the conductive sheet mounting base 2015 is also rectangular, corresponding to the first electrical contact 21. A first copper sheet 2016 is provided at the upper end of the conductive sheet mounting base 2015, and a second copper sheet 2017 is provided on the side of the conductive sheet mounting base 2015 on the third slot 2013 near the fourth slot 2014. The first copper sheet 2016 is used to transmit the power supply current in the track 201. The first copper sheet 2016 is in contact with the first conductive spring 211 and is electrically connected. The second copper sheet 2017 is used to transmit the control signal current in the track 201. The second copper sheet 2017 is in contact with the second conductive spring 212 and is electrically connected. The fourth slot 2014 is symmetrically arranged with the third slot 2013, has a similar structure, and has the same function, so it will not be described in detail here.

[0068] The track light assembly 200 also includes an electrical device 202, which is mounted on the track 201. In the embodiments of this application, the electrical device 202 is used for illustrative purposes only and is not intended to limit the scope of the invention. Those skilled in the art will understand that the electrical device 202 can be of various types suitable for installation on the track 201. For example, the electrical device 202 can be a lighting fixture, monitoring equipment, intelligent control device, or sensor module, or a power supply device such as a drive power supply, etc., and the present invention does not limit this.

[0069] In one optional embodiment, the electrical device 202 is a driving power supply, which can also be directly coupled to the track 201. Other electrical devices 202, such as lighting fixtures, monitoring equipment, intelligent control devices, or sensor modules, can be coupled to the driving power supply. In this case, the driving power supply and the track adapter are integrated, meaning the driving power supply is located within the track adapter to receive mains power and convert it into the power required by the other electrical devices 202. Alternatively, other electrical devices 202, such as lighting fixtures, monitoring equipment, intelligent control devices, or sensor modules, can also have their own driving devices to achieve power conversion; this invention does not limit this.

[0070] Please see Figure 12 As shown, this application also provides a track light assembly 300, including a track 201, an electrical device 202 (not shown), an electrical connection device 100, an electrical connection device 101, and an electrical connection device 102. The electrical device 202 is installed on the track 201, and the track 201 is connected in various ways through the electrical connection device 100, the electrical connection device 101, and the electrical connection device 102.

[0071] In summary, the electrical connection device 100 of the present invention comprises a first connecting portion 2, a second connecting portion 3 located at both ends of the main body 1, a substrate 11 extending from the main body 1, and a plug-in assembly 12. Both the first connecting portion 2 and the second connecting portion 3 include symmetrically spaced first electrical contacts 21 and second electrical contacts 22. The plug-in assembly 12 is disposed between the first electrical contacts 21 and the second electrical contacts 22, forming a triangular arrangement in the vertical cross-section. Unlike existing electrical connection devices, this application divides the connection portion into the first electrical contact 21, the second electrical contact 22, and the plug-in assembly 12 instead of integrating them together. This reduces the thickness of the first connecting portion 2 connected to the track 201, making it more flattened and indirectly reducing the thickness of the track 201. Thickness; at the same time, the first electrical contact 21 and the second electrical contact 22 are used for electrical connection with the track 201, and the plug-in assembly 12 is used for mechanical connection with the track 201. While ensuring stable and reliable connection, the structure of the electrical connection device 100 is simplified. The installation process only requires plugging to complete the connection, which is convenient for installation. Moreover, all three are inserted into the track 201 and will not protrude from the track 201, which is more aesthetically pleasing. At the same time, the spaced first electrical contact 21 and the second electrical contact 22 ensure the installation distance and reduce the possibility of short circuit. And by setting the base plate 11, the interior of the track 201 is blocked, which not only serves as a dustproof function, but also serves as an aesthetic function, solving the problems of complex structure, inconvenient connection with the track, and protrusion from the track in the existing electrical connection device.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
