Detailed Implementation

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] The core of this invention is to provide a battery structure that can be matched with various laptop computer bays with different soldered wire positions, exhibiting good versatility, significantly reducing costs, and providing design diversity. Another core aspect of this invention is to provide an electrical device incorporating the aforementioned battery structure.

[0054] The battery structure provided by this utility model includes a bracket 1, a control circuit board 6, a battery 5, and connector terminals 7. Please refer to [reference needed]. Figure 1 , Figure 16 .

[0055] The bracket 1 contains a circuit board storage slot 3, a battery slot 2, and a cable management slot 4. Several battery slots 2 can be provided, depending on the number of batteries to be placed. In one specific embodiment, the wall thickness 'a' of the battery slot 2 can be 1.2-1.6 mm, and the height 'c' can be 2.5-10.0 mm, with the height being greater than the thickness of the battery 5. The wall thickness 'b' at the bottom 46 of the circuit board storage slot 3 can be 1.0 mm; the bottom wall thickness 'd' of the cable management slot 4 can be consistent with the value 'b'.

[0056] Please refer to Figure 7 The circuit board storage slot 3 is equipped with a control circuit board 6. The control circuit board 6 may include a metal conductive component 61 and a solder component 62. The metal conductive component 61 may be a conductive component made of materials such as nickel, copper, or aluminum. The solder component 62 is connected to the copper wire inside the main control circuit board and is conductive.

[0057] Please refer to Figure 15 The battery 5 includes tabs 51, specifically, the positive and negative tabs of the battery 5 are stacked with corresponding metal conductive parts 61 on the control circuit board 6, and the circuit connection is fastened by laser welding, resistance welding and soldering processes.

[0058] The soldering component 62 is stacked with the first end 71 of the connector terminal 7 and connected and fastened by soldering.

[0059] like Figure 8 The connector terminal 7 includes a first end 71, a self-adjusting part 72, and a second end 73. The second end 73 is located outside the bracket 1. The first end 71 extends into the circuit board storage slot 3 and is connected to the control circuit board 6. Specifically, the first end 71 is the metal wire at the end of the connector. The metal wire can be connected to the solder joint 62 on the control circuit board 6.

[0060] The second end 73 extends out of the outside of the bracket 1, specifically the terminal head. The terminal head is also fixed with several metal wires, which can be plugged into the main unit system to form a connection between the battery structure and the main unit system.

[0061] like Figure 3 The cable management channel 4 is provided with at least two cable outlets 41. The self-adjusting part 72 can extend to the outside of the bracket 1 from either cable outlet buckle. Different cable outlets 41 correspond to different extension lengths of the self-adjusting part 72. If the arrangement direction of the two cable outlets 41 is the first direction, then the direction in which the self-adjusting part 72 extends out of the cable management channel 4 is the second direction. Figure 16 The first direction is the x-axis, and the second direction is the y-axis.

[0062] The self-adjusting part 72 has a portion located within the cable management groove 4 and connected to the first end 71, and also a portion extending out of the cable management groove 4. By extending from the outlet 41 at different positions, the length of the self-adjusting part 72 extending out of the cable management groove 4 can be changed to accommodate different interface positions in different laptop battery compartments. By adaptively changing the position of the self-adjusting outlet 41 according to different battery compartment interface positions, laptops with different battery compartment interface positions can use the same battery structure for connection, improving the commonality of laptop battery structures. The length of the connector terminal 7 extending out of the bracket 1 can be matched with various main unit compartment laptops with different soldered cable exit positions, significantly reducing costs and increasing design versatility.

[0063] In addition, in this embodiment, the cable management channel 4 is placed inside the bracket 1, which maximizes the use of the battery structure space, does not affect the space of the laptop, reduces the size of the laptop, and is conducive to miniaturization design.

[0064] Based on the above embodiments, such as Figure 8 As shown, the self-adjusting part 72 includes a wire portion and an insulation portion. The insulation portion wraps around the wire portion to form a plurality of wrapping portions 721 and an exposed portion 722 located between two adjacent wrapping portions 721. Each exposed portion 722 can pass through the outlet 41, and each exposed portion 722 can be bent in the cable management groove 4 so that the adjacent wrapping portion 721 can extend from the outlet 41 to the outside of the bracket 1.

[0065] The wire part includes several metal conductive wires, and the insulation part includes, but is not limited to, acetate cloth. The insulation part can be used to shape and bundle the several metal conductive wires into a circle. The size of the bundle can be 3.6mm, but is not limited to this.

[0066] The exposed portion 722 refers to the part without any covering and with the wires exposed. Multiple exposed portions 722 are provided, and the number of exposed portions 722 can be the same as or greater than the number of wire outlets 41. By exposing the wires, material stress can be reduced, shaping can be facilitated, and the self-adjusting portion 72 can be adjusted to extend to different positions of the wire outlets 41, thus making the battery structure more versatile.

[0067] Any exposed portion 722 can pass through the outlet 41. In use, bending of any exposed portion 722 will cause its adjacent wrapped portion 721 to extend out of the bracket 1 through the outlet 41. Here, "adjacent" specifically refers to... Figure 8 As shown, the wrapping portion 721 is located away from the first end 71. When wrapping portions 721 are provided on both sides of the curved exposed portion 722, the wrapping portion 721 located away from the first end 71 extends out from the outlet 41.

[0068] like Figure 2 In the three different states shown, the part that contacts the outlet 41 is always the wrapping part 721, which avoids direct contact with the exposed part 722 and causes wear or damage, thus ensuring effective protection for the connector terminal 7.

[0069] In this embodiment, the length of the exposed portion 722 can be set to 5mm, which is preferably consistent with the diameter of the outlet 41, so that the bending of each exposed portion 722 can allow its corresponding adjacent wrapping portion 721 to smoothly extend from the outlet 41 outside the bracket 1, thereby improving the reliability of adjustment.

[0070] In addition, a wrapping layer for wrapping is also provided at the first end 71. Specifically, the first end 71 is the part of the power metal conductor where the outer insulation has been removed to expose the inner metal wires. This part is shaped and molded with materials such as acetate cloth, so that the power metal conductive wires are on the same horizontal line and distributed at a certain distance. Figure 8 The meaning is as shown.

[0071] Based on any of the above embodiments, please refer to Figure 5 The cable management groove 4 is provided with multiple auxiliary ribs 42. One side of the auxiliary rib 42 is connected to the hole wall of the cable outlet 41, and the other side of the auxiliary rib 42 extends away from the cable outlet 41.

[0072] Along the direction close to the outlet 41, the distance between the inner walls of the two auxiliary ribs 42 corresponding to each outlet 41 gradually decreases.

[0073] The auxiliary rib 42 is located in the cable management groove 4. Specifically, it can be set to have an arc-shaped structure, which can provide a guiding function, so that the exposed part 722 can bend smoothly and the adjacent wrapped part 721 can extend smoothly from the corresponding cable outlet 41 position, ensuring the reliable adjustment effect of the self-adjusting part 72, improving the applicability of the battery structure, and enhancing the reliability and convenience of operation.

[0074] In one specific embodiment, the auxiliary rib 42 is reinforced and fixed by a rounded corner at the bottom 46 of the cable management groove 4, which ensures the reliability of the connection between the auxiliary rib 42 and the hole wall of the cable outlet 41 and ensures the overall structural strength.

[0075] The height of auxiliary rib 42 can be set to be less than the height of support 1, and the height direction here is... Figure 16 The z-direction is shown in the diagram.

[0076] Each outlet 41 has two auxiliary ribs 42 forming a figure-eight structure. Along the direction close to the outlet 41, the distance between the inner walls of the figure-eight structure gradually decreases, so that the self-adjusting part 72 can reliably reach the corresponding outlet 41 position through the guidance of the auxiliary ribs 42 and smoothly pass through the outlet 41 to extend out of the bracket 1 and connect to the second end 73.

[0077] Based on any of the above embodiments, please refer to Figure 3 The cable outlet 41 includes a first opening 411 away from the bottom 46 of the cable tray 4 and a second opening 412 close to the bottom 46 of the tray. The first opening 411 and the second opening 412 are connected, and the size of the first opening 411 is smaller than the size of the second opening 412. The wrapping part 721 is disposed in the second opening 412.

[0078] By limiting the dimensions of the first port 411 and the second port 412, the wrapping portion 721 of the self-adjusting portion 72 can be inserted into the outlet port 41 through an interference fit, thereby ensuring the reliable fixation of the self-adjusting portion 72 relative to the outlet port 41.

[0079] In this embodiment, the size difference between the first opening 411 and the second opening 412 can be set to 1.6mm, the width f of the corresponding cable outlet 41 can be set to 4mm, the height e of the second opening 412 can be set to 3.5mm, and the height h of the bottom 46 of the cable management groove 4 is not limited and can be determined according to the actual situation.

[0080] The dimensional difference between the first port 411 and the second port 412 can be achieved by providing a protrusion at the top of the outlet 41, such as... Figure 6 The width g of the protrusion relative to the inner wall of the second opening 412 is 0.8mm. In order to ensure reliable protection of the wrapping part 721, the edge of the protrusion can be rounded on the basis of interference fit, so as to facilitate the entry of the wrapping part 721 and avoid the sharp corner of the wire from scratching.

[0081] Based on any of the above embodiments, please refer to Figure 5 The cable management trough 4 includes a first sidewall 47 and a second sidewall 49 disposed opposite to it. The first sidewall 47 is provided with at least two cable outlets 41, and the second sidewall 49 is provided with a clearance opening 491. The first end 71 extends into the circuit board storage trough 3 through the clearance opening 491.

[0082] The first sidewall 47 and the second sidewall 49 form the two sidewalls of the cable management groove 4. The second sidewall 49 also serves as a retaining rib between the circuit board storage groove 3 and the cable management groove 4, which can separate the two grooves. The wall thickness of the second sidewall 49 can be 1mm, and the height of the second sidewall 49 is lower than the height of the bracket 1.

[0083] The first end 71 needs to be connected to the control circuit board 6. Therefore, based on the separation between the circuit board storage slot 3 and the cable management slot 4, an avoidance opening 491 is provided to facilitate the first end 71 to extend into the circuit board storage slot 3, so that the metal wire of the first end 71 can be connected to the soldering part 62 on the control circuit board 6 to complete the fixation.

[0084] The specific form of the clearance opening 491 can be square, rectangular, or other forms, without much restriction.

[0085] Based on any of the above embodiments, please refer to Figure 9 , Figure 10 , Figure 11 It also includes a first mounting cover 9, which is detachably connected to the cable management channel 4. The first mounting cover 9 can close or open the top 48 of the cable management channel 4.

[0086] The top of the slot 48 and the bottom of the slot 46 are relative to Figure 6 In the z-direction, the top of the groove 48 is open. The top of the groove 48 can be exposed when the self-adjusting part 72 is adjusted or installed by the first mounting cover 9, and the top of the groove 48 can be closed when the adjustment or installation is completed.

[0087] Specifically, the first mounting cover 9 can be reliably connected to the cable management channel 4 by snapping, fastening, or with the aid of auxiliary parts, so as to facilitate the opening and closing of the first mounting cover 9 relative to the cable management channel 4.

[0088] In one specific embodiment, the first mounting cover 9 is snapped into the cable management groove 4. When adjusting and installing the self-adjusting part 72, the first mounting cover 9 can be removed, and after installation, the first mounting cover 9 can be snapped onto the top 48 of the groove of the cable management groove 4. The operation is simple and convenient.

[0089] In this embodiment, the first mounting cover 9 closes or opens the cable management groove 4. Specifically, the first mounting cover 9 can close or open all areas of the top 48 of the cable management groove 4, or it can refer to a portion of the cable management groove 4 that can be closed or opened. Here, the portion specifically refers to the area of ​​the top 48 of the groove corresponding to the self-adjusting part 72.

[0090] For example, the first mounting cover 9 can close or open all areas of the top 48 of the cable management channel 4. When the first mounting cover 9 is in the open state relative to the cable management channel 4, the portion of the self-adjusting part 72 located in the cable management channel 4 and the first end 71 are both exposed. At this time, the self-adjusting part 72 can be self-adjusted so that it can pass out from the corresponding required outlet 41 to be suitable for different battery compartment interface positions.

[0091] Based on any of the above embodiments, please refer to Figure 5 , Figure 20 , Figure 21 At least one of the first sidewall 47 and the second sidewall 49 is provided with a pivot 43 on the side near the inside of the cable tray 4. The first mounting cover 9 is rotatably connected to the first sidewall 47 or the second sidewall 49 via the pivot 43.

[0092] The pivot 43 enables a rotatable connection between either the first sidewall 47 or the second sidewall 49 and the first mounting cover 9. This allows the first mounting cover 9 to open or close the cable management channel 4 via a rotatable connection, facilitating reliable and convenient operation according to actual operational needs. Specifically, rotating the first mounting cover 9 downwards to a horizontal position corresponds to closing the cable management channel 4; rotating it upwards in reverse corresponds to opening the cable management channel 4.

[0093] In this embodiment, if the rotating shaft 43 is set as a damping rotating shaft, the first mounting cover 9 can rotate to a certain angle and then stop at this position until an external force pushes the first mounting cover 9 to continue rotating. No other parts are needed, and the structure is simple and effective.

[0094] In this embodiment, if the rotating shaft 43 is set as a normal rotating shaft, the first mounting cover 9 does not need to be locked when it is rotated to open. When it is rotated to close the cable management groove 4, a locking element needs to be set. The locking element can keep the first mounting cover 9 reliably locked relative to the cable management groove 4, and can ensure that the first mounting cover 9 will not open without the action of external force, thus ensuring the reliability of the first mounting cover 9.

[0095] In this embodiment, at least one of the first sidewall 47 and the second sidewall 49 is provided with a pivot 43, which can provide support for the rotation of the first mounting cover 9.

[0096] In one specific embodiment, both the first sidewall 47 and the second sidewall 49 are provided with a rotating shaft 43. The axial direction of the rotating shaft 43 is parallel to the axial direction of the cable outlet 41. The two different positions of the first mounting cover 9 can be connected to the rotating shaft 43 on the first sidewall 47 and the second sidewall 49 respectively, so as to ensure the reliable stability of the first mounting cover 9 when rotating, and to ensure the reliable opening and closing of the cable management groove 4.

[0097] Based on any of the above embodiments, such as Figure 10 , Figure 11 As shown, the first mounting cover 9 includes at least one hook 92 and at least one rotating part 91, the rotating part 91 and the rotating shaft 43 are rotatably connected, and the hook 92 is engaged with the slot 471 of the first side wall 47.

[0098] like Figure 5 , Figure 6 As shown, one or more card slots 471 can be provided. If multiple card slots 471 are provided, the arrangement direction of the multiple card slots 471 is consistent with the arrangement direction of at least two cable outlets 41.

[0099] In this embodiment, the slot 471 can be used to reliably lock the first mounting cover 9 into the cable management groove 4. Specifically, after the first mounting cover 9 is rotated into position relative to the cable management groove 4, it can be connected by the slot 471 and the hook 92.

[0100] The disengagement of the hook 92 and the slot 471 is specifically achieved by ensuring that the width of the hook 92 is less than the width of the slot 471. Here, the width direction is... Figure 10 The x-axis direction allows the hook 92 to be released from the slot 471 by pressing it with external force, so that the first mounting cover 9 can rotate freely.

[0101] The slot 471 of the first sidewall 47 is provided, as follows: Figure 9 , Figure 10 As shown, the minimum distance between two adjacent auxiliary ribs 42 forming an inverted V-shape is greater than the width of the slot 471, ensuring that the hook 92 and the slot 471 can be smoothly engaged or disengaged.

[0102] In this embodiment, the rotating part 91 can specifically be configured as a ring, such as... Figure 10 As shown, the inner diameter of the ring is larger than the outer diameter of the shaft 43, so that the two can be reliably assembled and fastened. Here, the inner diameter is slightly larger than the outer diameter. After assembly, the ring can rotate smoothly and reliably relative to the shaft 43.

[0103] In addition, to further facilitate the assembly of the rotating part 91, a guide angle can be provided on the top of the rotating shaft 43. The guide angle facilitates the reliable assembly and disassembly of the rotating part 91 and the rotating shaft 43. The specific angle is not limited and can be set according to the actual situation.

[0104] Based on any of the above embodiments, please refer to Figure 5 The cable management groove 4 has a recessed portion 44 at one end near the rotating shaft 43, and the plane of the recessed portion 44 is lower than the plane of the bottom 46 of the cable management groove 4. During the upward rotation of the first mounting cover 9 around the rotating shaft 43, the edge of the first mounting cover 9 connected to the rotating shaft 43 moves along the direction close to the recessed portion 44, and the edge of the first mounting cover 9 extends into the recessed portion 44 to stop. In this state, the first mounting cover 9 no longer rotates and can be adjusted by the self-adjusting part 72. During the downward rotation of the first mounting cover 9 around the rotating shaft 43 to the horizontal closed state, the edge of the first mounting cover 9 connected to the rotating shaft 43 moves away from the recessed portion 44, and the first mounting cover 9 closes the cable management groove 4 and no longer rotates. The first mounting cover 9 is locked by the hook 92 engaging with the slot 471 of the first side wall 47.

[0105] The recessed portion 44 provides clearance during the rotational opening or closing of the first mounting cover 9, allowing the first mounting cover 9 to open or close smoothly.

[0106] Based on the above, an arc-shaped guide portion 45 is provided on the side of the recessed portion 44 away from the bottom of the groove 46. The arc-shaped guide portion 45 can provide guidance for the first mounting cover 9 to rotate open or close. Combined with the avoidance function of the recessed portion 44, the first mounting cover 9 can be reliably opened and closed.

[0107] In this embodiment, the plane of the recessed portion 44 is set lower than the plane of the bottom of the groove 46. In other words, the height of the recessed portion 44 is lower than the height of the bottom of the groove 46. The specific difference between the two can be determined based on the actual situation when the first mounting cover 9 rotates, without too many restrictions.

[0108] Based on any of the above embodiments, please refer to Figure 12 , Figure 13 , Figure 14 It also includes a second mounting cover 10, which covers the circuit board storage slot 3 and the portion of the top 48 of the slot corresponding to the first end 71.

[0109] The second mounting cover 10 can be fixed relative to the bracket 1 by a detachable connection. The specific detachable connection method can be fastening, snap-fitting, or other forms, and is not limited.

[0110] For example, the second mounting cover 10 is connected to the second side wall 49 of the cable management groove 4, the second mounting cover 10 is connected to the circuit board storage groove 3, and the second mounting cover 10 is connected to the bracket 1. As long as the reliable installation effect of the second mounting cover 10 can be guaranteed, the second mounting cover 10 does not need to be removed under normal circumstances. The second mounting cover 10 is only required to be removed when it is necessary to remove or repair the control circuit board 6.

[0111] The second mounting cover 10 can cover the portion of the top 48 of the groove corresponding to the first end 71. This setting is based on the fact that the position of the first end 71 does not need to be changed after being connected to the control circuit board 6. The self-adjusting part 72 can be exposed by opening the first mounting cover 9. After the first end 71 and the control circuit board 6 are installed, they can be reliably placed in the space formed by the second mounting cover 10 and the bracket 1, avoiding the risk of exposed metal wires.

[0112] The second mounting cover 10 can protect the first end 71 and the control circuit board 6 from external damage, thereby enhancing the structural strength of the entire battery structure.

[0113] like Figure 10 The thickness value l of the first mounting cover 9 can be kept consistent with the thickness value k of the second mounting cover 10.

[0114] Based on any of the above embodiments, please refer to Figure 14 The second mounting cover 10 is provided with a snap-fit ​​component 101 on the side facing the circuit board storage slot 3, and the bracket 1 is provided with at least one engaging part 8, which engages with the snap-fit ​​component 101.

[0115] like Figure 3As shown, the engaging part 8 can be placed in the part of the cable management groove 4 corresponding to the first end 71, or it can be placed in the circuit board storage groove 3. The number of engaging parts 8 in the circuit board storage groove 3 is not limited and can be determined according to the actual situation.

[0116] When removing or installing the second mounting cover 10, it can be removed or installed by manually lifting it upwards or pressing it downwards, which is simple and convenient.

[0117] Based on any of the above embodiments, please refer to Figure 18 The first plane S1 of the first mounting cover 9, which is away from the cable management groove 4, and the second plane S2 of the second mounting cover 10, which is away from the cable management groove 4, are both flush with the top plane S3 of the bracket 1, ensuring the aesthetics and neatness of the battery structure.

[0118] In practical applications, please refer to Figures 15 to 20 The battery assembly process is as follows:

[0119] The control circuit board 6 is placed horizontally. After the tabs 51 on the battery 5 are stacked with the metal conductive parts 61 of the control circuit board 6, the circuit connection can be achieved by laser welding, resistance welding, or soldering. The first end 71 of the connector terminal 7 and the soldering parts 62 of the control circuit board 6 are connected and secured by soldering. After the battery semi-finished product is assembled, the charging and discharging energy storage function of the battery structure can be realized.

[0120] Place the bracket 1 horizontally, place the battery semi-finished product horizontally downward into the bracket 1, place the batteries 5 into the corresponding battery slots 2 respectively, place the control circuit board 6 into the circuit board storage slot 3, and the self-adjusting part 72 of the connector terminal 7 extends out of the bracket 1 from any of the outlets 41.

[0121] The second mounting cover 10 is installed by engaging the snap-fit ​​part 101 of the second mounting cover 10 with the snap-fit ​​part 8 inside the bracket 1.

[0122] The rotating part 91 of the first mounting cover 9 is connected to the rotating shaft 43 provided in the cable management groove 4, so that the first mounting cover 9 can rotate relative to the cable management groove 4.

[0123] Flip the first mounting cover 9 horizontally downwards until it is horizontal, and engage the hook 92 with the slot 471 of the first side wall 47 to complete the installation of the first mounting cover 9 and form the main battery component.

[0124] The first insulating protective film 11 and the second insulating protective film 12 are respectively attached to the top and bottom of the battery body component to provide insulation coverage, prevent the battery body component from contacting other metal materials in the battery compartment, make the battery structure connection firm and reliable, and improve the reliability of the battery structure.

[0125] In practice, when the battery structure is applied to laptops with different battery wire lengths and various soldering wire exit positions in the main unit compartment, if adjustments are required, the first mounting cover 9 is opened, and the part of the self-adjusting part 72 extending out of the wire exit 41 is pulled out. By pulling with external force, the exposed part 722 corresponding to the other wire exit 41 that needs to be adjusted can be bent and deformed. At this time, the wrapping part 721 adjacent to this bent and deformed exposed part 722 can extend out of the other wire exit 41 to achieve adjustment.
