Technical Field

[0001] This invention relates to the field of smart furniture technology, and in particular to a hidden battery pack structure and a smart chair. Background Technology

[0002] With the continuous improvement of living standards and the advancement of science and technology, users have increasingly higher requirements for the comfort of furniture. In particular, to adapt to different user groups and meet the needs of different scenarios, many smart furniture products have emerged, especially swivel chairs, which are equipped with functions such as height adjustment, backrest adjustment, massage, health monitoring, and seat firmness adjustment. For example, Chinese invention patent application number 201611189454.3 discloses a chair equipped with pneumatic massage and backrest adjustment functions; Chinese invention patent application number 201810453661.8 discloses a chair equipped with health monitoring, reminder, and seat firmness adjustment functions; and Chinese invention patent application number 201810719820.4 discloses a chair equipped with height adjustment, storage, and fresh air supply functions.

[0003] Regardless of the type of smart furniture, such as chairs, tables, or beds, its intelligence requires a power supply. To make smart furniture more convenient to use, battery packs are usually installed, especially for swivel chairs. If the battery pack is placed inside the smart furniture, it will increase the overall size of the smart furniture; if the battery pack is placed on the outside, it will increase the risk of the battery pack being bumped or knocked, and it will also affect the aesthetics of the smart furniture.

[0036] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] This application provides a concealed battery pack structure. The concealed battery pack structure includes a connecting component, a housing, and a battery pack. The connecting component has a first clearance hole for connecting to the chassis of a seat. The housing has a mounting cavity and a second clearance hole. The housing is electrically connected to the connecting component, and the second clearance hole communicates with the first clearance hole. Both the first and second clearance holes are used to accommodate the seat legs. The battery pack is disposed within the mounting cavity and is electrically connected to the housing.

[0040] The aforementioned concealed battery pack structure allows the connecting component to connect to the seat chassis. The connecting component has a first clearance hole, and the housing has a second clearance hole. The first and second clearance holes are used to jointly house the seat legs, so that the connecting component is located on the back of the seat and surrounds the seat legs. The battery pack is located in the mounting cavity and electrically connected to the connecting component. This allows the battery pack to be well mounted on the seat legs through the housing and connecting component. Thus, with minimal impact on the overall footprint of the seat, the seat and housing effectively protect the battery pack, reducing the risk of impacts and improving the aesthetics.

[0041] It should be noted that the increasing intelligence of seating has led to a continuous increase in the overall footprint of the seats, such as... Figure 1As shown, a casing for housing the battery pack is placed at the bottom of the seat, which increases the overall footprint of the seat, affecting its versatility. Furthermore, the battery pack is difficult to disassemble and maintain, impacting the ease of use. If the battery pack is placed on the side of the seat to reduce the increased footprint, it increases the risk of impacts and shortens the seat's lifespan. Therefore, in this application, the battery pack is placed in the seat leg, where there is remaining space for the user's feet. By surrounding the seat leg, the impact on the overall volume of the seat is effectively reduced, and the casing and seat provide better protection for the battery pack, effectively minimizing its impact.

[0042] It should also be noted that, especially for swivel chairs, which have only one rotating leg relative to the seat base, simply mounting the battery pack on the leg or directly on the back of the seat away from the seat surface will cause the battery pack wires to become tangled in the leg. If the battery pack is mounted directly on the back of the seat near the leg, it will significantly reduce the volume of one side of the leg, thus affecting the user's leg positioning. Excessive space for users' feet at the chair legs can negatively impact their user experience. Therefore, in this application, the connecting component and the housing for the battery pack are arranged around the chair legs, with the battery pack electrically connected to the connecting component, which is fixed to the seat. This effectively balances the circumferential space around the chair legs, minimizing the impact on the user's foot space and the overall floor area of ​​the seat. The seat also reduces the risk of the battery pack being bumped or knocked. Furthermore, battery pack maintenance can be performed simply by removing the housing from the connecting component, making it highly convenient to use.

[0043] To better understand the concealed battery pack structure of this application, the following further explanation is provided:

[0044] Please refer to the following: Figures 2 to 4 One embodiment of the concealed battery pack structure 10 includes a connecting assembly 100, a housing 200, and a battery pack 300. The connecting assembly 100 has a first clearance hole 101 and is used to connect to the chassis of the seat. The housing 200 has a mounting cavity 201 and a second clearance hole 202. The housing 200 is electrically connected to the connecting assembly 100, and the second clearance hole 202 communicates with the first clearance hole 101. The first clearance hole 101 and the second clearance hole 202 are used to jointly accommodate the seat legs. The battery pack 300 is disposed within the mounting cavity 201 and is electrically connected to the housing 200.

[0045] The aforementioned concealed battery pack structure 10 allows the connecting component 100 to connect to the seat chassis. The connecting component 100 has a first clearance hole 101, and the housing 200 has a second clearance hole 202. The first clearance hole 101 and the second clearance hole 202 are used to jointly house the seat legs, so that the connecting component 100 is located on the back of the seat and surrounds the seat legs. The battery pack 300 is located in the mounting cavity 201 and electrically connected to the connecting component 100. This allows the battery pack 300 to be well mounted on the seat legs through the housing 200 and the connecting component 100. Thus, with minimal impact on the overall floor space of the seat, the seat and housing 200 effectively protect the battery pack, reducing the risk of impacts to the battery pack and improving its aesthetics.

[0046] Please refer to the following: Figures 2 to 4 In one embodiment, the extension direction of the first clearance hole 101 is the same as the extension direction of the second clearance hole 202. The hole walls of the first clearance hole 101 and the second clearance hole 202 are both arranged adjacent to the seat legs, which effectively reduces the mechanical interference between the connecting assembly 100, the housing 200 and the seat legs, and better ensures the connection stability of the connecting assembly 100 and the housing 200 when the seat legs rotate, thereby better ensuring the electrical connection stability of the connecting assembly 100 and the housing 200 when the seat is used.

[0047] Please refer to the following: Figures 2 to 3 In one embodiment, the connecting assembly 100 includes a fixing member 110a, a plug-in terminal 120a, and a conductive member 130a. A first clearance hole 101 is formed on the fixing member 110a. The fixing member 110a is used to connect with the chassis of the seat. The plug-in terminal 120a is fixed to the fixing member 110a. The conductive member 130a is connected to the fixing member 110a and is electrically connected to the plug-in terminal 120a. Further, the housing 200 is fixed to the fixing member 110a and is electrically connected to the conductive member 130a. It is understood that by connecting the fixing member 110a to the seat and fixing the housing 200 to the fixing member 110a, both the housing 200 and the connecting component 100 are fixedly connected to the seat. Furthermore, the conductive member 130a is connected to the fixing member 110a and electrically connected to the plug terminal 120a. This ensures that the battery pack wires will not get tangled in the seat legs when the seat rotates, reducing the problem of battery pack wire breakage and better ensuring the electrical connection stability of the battery pack, thereby better ensuring the functional stability of the seat.

[0048] Please refer to the following: Figures 4 to 6In one embodiment, the connection assembly 100 includes a connector 110, a connection terminal 120, and an electrical contact 130. A first clearance hole 101 is formed on the connector 110. The connector 110 is used to connect to the chassis of the seat. The connection terminal 120 is fixed to the connector 110. The electrical contact 130 is connected to the connector 110 and electrically connected to the connection terminal 120. The electrical contact 130 abuts against the housing 200. Further, the housing 200 is used to install on the seat leg. When the electrical contact 130 abuts against the housing 200, it is electrically connected to the housing 200. It is understandable that if the housing 200 were directly fixed to the seat, while having a certain gap between it and the seat legs, it would occupy a significant amount of circumferential space in the seat legs, thus affecting user convenience and user experience. Therefore, in this application, the housing 200 is fixed to the seat legs without any gap, and the connecting component 100 rotates and abuts against the housing 200 through the connecting terminal 120 and the electrical contact 130, thereby achieving electrical connection between the connecting component 100 and the battery pack. In this case, when the seat legs rotate, the battery pack wires will not get tangled in the seat legs, and the housing 200 and the seat legs are highly compact, effectively reducing the space occupied by the battery pack in the circumferential space of the seat legs, thus better ensuring user convenience and user experience.

[0049] Please refer to the following: Figures 4 to 6 In one embodiment, the electrical contact 130 includes a conductor 131 and an electrical contact spring 132. The conductor 131 is connected to the connector 110 and electrically connected to the connection terminal 120. The electrical contact spring 132 is electrically connected to the conductor 131. The electrical contact spring 132 is disposed toward the housing 200 and abuts against the side of the housing 200 near the connector 110. When the electrical contact spring 132 abuts against the housing 200, it is electrically connected to the housing 200, thereby better ensuring the electrical connection between the connection assembly 100 and the battery pack.

[0050] Please refer to the following: Figures 4 to 6In one embodiment, the housing 200 includes a mounting body 210 and an annular slide rail 220. A mounting cavity 201 and a second clearance hole 202 are formed on the mounting body 210. The annular slide rail 220 is insulatedly connected to the side of the mounting body 210 near the electrical contact spring 132. A battery pack 300 is mounted on the mounting body 210 and is electrically connected to the annular slide rail 220. The annular slide rail 220 is arranged around the outer periphery of the second clearance hole 202. The electrical contact spring 132 abuts against the annular slide rail 220 and is slidably connected to the annular slide rail 220. When the electrical contact spring 132 abuts against the annular slide rail 220, it is electrically connected to the annular slide rail 220. It can be understood that "supporting" means abutting and having a certain force pushing against it. That is, the electric contact spring 132 has a certain force abutting against and pushing against the annular slide rail 220, thereby making the annular slide rail 220 insulated on the mounting body 210. The annular slide rail 220 and the electric contact spring 132 abut against each other to achieve mutual electrical connection, thereby effectively reducing the short circuit problem of the battery pack.

[0051] Please refer to the following: Figures 4 to 6 In one embodiment, the contact spring 132 includes a positive electrode spring 1321 and a negative electrode spring 1322. Further, the annular slide rail 220 includes a first slide rail 221 and a second slide rail 222, which are spaced apart on the mounting body 210. Both the first and second slide rails 221 and 222 are arranged around the outer periphery of the second clearance hole 202, and both are insulated from the mounting body 210. The positive electrode spring 1321 abuts against the first slide rail 221 and is slidably connected to it. When 21 is pressed against the first slide rail 221, it is electrically connected to the first slide rail 221. The first slide rail 221 is electrically connected to the battery pack 300. The negative electrode spring 1322 is pressed against the second slide rail 222 and is slidably connected to the second slide rail 222. When the negative electrode spring 1322 is pressed against the second slide rail 222, it is electrically connected to the second slide rail 222. The second slide rail 222 is electrically connected to the battery pack 300. This effectively achieves mutual insulation between the positive and negative electrodes of the battery pack, thereby better ensuring the functional stability of the seat.

[0052] Please refer to the following: Figures 4 to 6In one embodiment, the mounting body 210 has a first connecting hole 203, which communicates with the mounting cavity 201. Further, the first slide rail 221 includes a first annular rail body 2211 and a first through-body 2212. The first annular rail body 2211 is connected to the first through-body 2212, the first through-body 2212 passes through the first connecting hole 203 and is located at the mounting cavity 201, and the first through-body 2212 is electrically connected to the battery pack 300. It is understandable that if the opposite sides of the first slide rail 221 were to abut against the battery pack and the electrical contact spring 132 respectively to achieve mutual electrical connection, the mounting body 210 would need to open an annular hole to snap and fix the first slide rail 221. This would increase the machining accuracy of the mounting body 210, otherwise it would affect the fixing stability of the first slide rail 221, and thus affect the electrical connection stability of the battery pack. Therefore, in this application, only the first connecting hole 203 with poor accuracy is opened at the corresponding position to allow the first penetrating body 2212 to pass through, which can achieve electrical connection with the battery pack. The first annular rail body 2211 is directly fixed to the surface of the mounting body 210. This effectively reduces the machining accuracy requirements of the hidden battery pack structure 10 while achieving the electrical connection stability between the first slide rail 221 and the battery pack.

[0053] Please refer to the following: Figures 4 to 6 In one embodiment, the mounting body 210 also has a second connecting hole 204, which communicates with the mounting cavity 201. Further, the second slide rail 222 includes a second annular rail body 2221 and a second through-body 2222. The second annular rail body 2221 is connected to the second through-body 2222. The second through-body 2222 passes through the second connecting hole 204 and is located at the mounting cavity 201. The second through-body 2222 is electrically connected to the battery pack 300. This effectively reduces the processing precision requirements of the concealed battery pack structure 10 while ensuring the electrical connection stability between the second slide rail 222 and the battery pack.

[0054] Please refer to the following: Figures 7 to 8In one embodiment, the positive electrode spring 1321 includes a first support portion 132a, a first reinforcing portion 132b, and a first spring portion 132c. The first support portion 132a is electrically connected to the conductive member 131. The first support portion 132a intersects with the first spring portion 132c, and one end of the first support portion 132a is connected to one end of the first spring portion 132c. The other end of the first spring portion 132c is located on the side of the first support portion 132a closer to the mounting body 210. The first reinforcing portion 132b is located on the side of the first support portion 132a closer to the mounting body 210. At the connection between the first support portion 132a and the first spring portion 132c, and the first reinforcing portion 132b is located on the side of the first support portion 132a near the mounting body 210, and both ends of the first reinforcing portion 132b are respectively connected to the first support portion 132a and the first spring portion 132c, the first spring portion 132c abuts against the first slide rail 221 and is slidably connected to the first slide rail 221, and the first spring portion 132c is electrically connected to the first slide rail 221 when it abuts against the first slide rail 221. It is understood that a spring sheet is an elastic sheet-like structure. Although a spring sheet has good elastic strength, its rebound effect will be affected under long-term contact, thus affecting the contact effect. That is, the spring sheet may have poor contact with the plane when it is pressed against it, which in turn affects the electrical connection effect. Therefore, in this application, the first reinforcing part 132b is located at the connection between the first support part 132a and the first spring sheet part 132c, and the first reinforcing part 132b is located at the first support part 132a. The side near the mounting body 210 and both ends of the first reinforcing part 132b are connected to the first support part 132a and the first spring part 132c respectively, so that the first reinforcing part 132b strengthens the elastic strength of the first support part 132a and the first spring part 132c, thereby effectively improving the holding effect of the positive electrode spring 1321 on the first slide rail 221, that is, it improves the electrical connection stability between the positive electrode spring 1321 and the first slide rail 221, thereby better ensuring the functional stability of the seat.

[0055] Please refer to the following: Figures 7 to 8In one embodiment, a first abutting protrusion 132d is provided on the first spring piece 132c. The first abutting protrusion 132d is located on the side of the first spring piece 132c close to the mounting body 210, and the first abutting protrusion 132d abuts against the first slide rail 221 and is slidably connected to the first slide rail 221. When the first abutting protrusion 132d abuts against the first slide rail 221, the first spring piece 132c is electrically connected to the first slide rail 221. It is understood that both the first spring 132c and the first slide rail 221 are rigid components with electrical conductivity, which makes them prone to rubbing against each other and producing a harsh noise when the seat rotates, affecting the user's experience. Therefore, in this application, the first abutting protrusion 132d provided on the positive electrode spring 1321 abuts against the first slide rail 221. The provision of the first abutting protrusion 132d reduces the contact area between the first spring 132c and the first slide rail 221, thereby reducing friction and noise generated by friction, and improving the user's experience.

[0056] In one embodiment, a first abutting ball is further provided on the first spring portion. Further, a first circular groove is provided on the first abutting protrusion, the first abutting ball is engaged in the first circular groove, and the first abutting ball at least partially protrudes from the first abutting protrusion. The first abutting ball is rotatably connected to the first abutting protrusion within the first circular groove. The first abutting ball abuts against and is slidably connected to the first slide rail, and the first abutting protrusion is electrically connected to the first slide rail when the first abutting ball abuts against the first slide rail. It is understandable that even though the setting of the first abutting protrusion reduces the contact area between the first spring and the first slide rail, thereby reducing friction and the noise generated by friction, the actual friction and the noise generated by friction will still affect the user and reduce the user's user experience. Therefore, in this application, a first circular groove is formed on the first abutting protrusion to accommodate the first abutting ball. The setting of the first abutting ball effectively reduces the friction between the first spring and the first slide rail and the noise generated by friction, thereby further improving the user's user experience.

[0057] In one embodiment, a first oil reservoir is formed on the surface of the first bearing ball. Furthermore, a first oil reservoir cotton is also provided on the first spring piece, the first oil reservoir cotton is disposed in the first oil reservoir cotton, and the first oil reservoir cotton is wetted with lubricating oil. It is understood that the first supporting ball and the first supporting protrusion are conductive materials, and during the use of the seat, they may rust and oxidize. This causes the first supporting ball to rotate unevenly on the first supporting protrusion, resulting in increased friction between the first spring and the first slide rail and increased noise generated by friction, affecting the user's experience. Therefore, in this application, an oil-retaining cotton soaked in lubricating oil is provided on the first oil reservoir on the surface of the first supporting ball. During the rotation of the first supporting ball, at least part of the lubricating oil in the first oil-retaining cotton will flow out onto the first supporting ball or the first slide rail, thereby forming a protective film on the contact surface between the first supporting ball and the first slide rail over a long period of time. This also improves the smoothness of the rotation of the first supporting ball on the first slide rail, thus effectively ensuring the smoothness of the rotation of the first supporting ball on the first supporting protrusion over a long period of time, and better ensuring the user's experience during long-term use.

[0058] In one embodiment, the end of the first oil-retaining cotton furthest from the first oil-retaining groove is flush with the opening of the first oil-retaining groove, which further ensures that the lubricating oil in the first oil-retaining cotton can flow out at least partially to the first supporting ball or the first slide rail, thereby effectively ensuring the smooth rotation of the first supporting ball on the first supporting protrusion in the long term, and better ensuring the user's experience during long-term use.

[0059] In one embodiment, a first cotton-fixing groove is formed on the inner wall of the first circular groove. Furthermore, a first oil-soaked cotton is also provided on the first spring piece, the first oil-soaked cotton being disposed within the first cotton-fixing groove, and the first oil-soaked cotton at least partially protruding from the first cotton-fixing groove, or the end of the first oil-soaked cotton furthest from the first cotton-fixing groove being flush with the opening of the first cotton-fixing groove, and the first oil-soaked cotton being soaked in lubricating oil. This further effectively ensures the smooth rotation of the first supporting ball on the first supporting protrusion over a long period, and better ensures the user's experience during long-term use.

[0060] In one embodiment, the negative electrode spring includes a second support portion, a second reinforcing portion, and a second spring portion. The second support portion is electrically connected to the conductive member, intersects with the second spring portion, and one end of the second support portion is connected to the second spring portion. The other end of the second spring portion is located on the side of the second support portion closer to the mounting body. The second reinforcing portion is located at the connection between the second support portion and the second spring portion, and is located on the side of the second support portion closer to the mounting body. Both ends of the second reinforcing portion are respectively connected to the second support portion and the second spring portion. The second spring portion abuts against the second slide rail and is slidably connected to the second slide rail. When the second spring portion abuts against the second slide rail, it is electrically connected to the second slide rail, which improves the electrical connection stability between the negative electrode spring and the second slide rail, thereby better ensuring the functional stability of the seat.

[0061] In one embodiment, the second spring portion is provided with a second abutting protrusion. The second abutting protrusion is located on the side of the second spring portion closer to the mounting body, and the second abutting protrusion abuts against and is slidably connected to the second slide rail. The second spring portion is electrically connected to the second slide rail when the second abutting protrusion abuts against the second slide rail. It can be understood that the provision of the second abutting protrusion reduces the contact area between the second spring portion and the second slide rail, thereby reducing friction and noise generated by friction, and improving the user experience.

Further, a second circular groove is provided on the second abutting protrusion, and the second abutting ball is engaged within the second circular groove. The second abutting ball is rotatably connected to the second abutting protrusion within the second circular groove. The second abutting ball abuts against the second slide rail and is slidably connected to the second slide rail. The second abutting protrusion is electrically connected to the second slide rail when the second abutting ball abuts against the second slide rail. It can be understood that by forming a second circular groove on the second abutting protrusion to accommodate the second abutting ball, the provision of the second abutting ball effectively reduces friction between the second spring portion and the second slide rail, and the noise generated by friction, thereby further improving the user experience.

[0063] In one embodiment, a second oil reservoir is formed on the surface of the second supporting ball. Furthermore, a second oil reservoir is also provided on the second spring portion. The second oil reservoir is disposed in the second oil reservoir and is soaked in lubricating oil, which effectively ensures the smooth rotation of the second supporting ball on the second supporting protrusion over a long period of time, and better ensures the user's user experience during long-term use.

[0064] In one embodiment, the end of the second oil-retaining cotton away from the second oil-retaining groove is flush with the opening of the second oil-retaining groove, which further ensures that the lubricating oil in the second oil-retaining cotton can flow out at least partially to the second supporting ball or the second slide rail, thereby effectively ensuring the smooth rotation of the second supporting ball on the second supporting protrusion in the long term, and better ensuring the user's user experience during long-term use.

[0065] In one embodiment, a second cotton-fixing groove is formed on the inner wall of the second circular groove. Furthermore, a second oil-soaked cotton is also provided on the second spring piece, the second oil-soaked cotton being disposed within the second cotton-fixing groove, and the second oil-soaked cotton at least partially protruding from the second cotton-fixing groove, or the end of the second oil-soaked cotton furthest from the second cotton-fixing groove being flush with the groove opening, and the second oil-soaked cotton being soaked in lubricating oil. This further effectively ensures the smooth rotation of the second supporting ball on the second supporting protrusion over a long period, and better ensures the user's experience during long-term use.
