Description

Technical Field

[0001] The present application relates to the technical field of charging, and particularly to a battery charging stand. Background Art

[0002] Portable hand tools and mobile electronic devices are widely popular due to their convenience and high efficiency. These devices are usually equipped with detachable rechargeable batteries, which is not only environmentally friendly but also greatly reduces the long-term use cost through the repeated use of the batteries. To improve the charging efficiency, many devices are equipped with dedicated charging devices. However, traditional charging devices have some limitations. They can often only charge one battery at a time, which is not efficient enough in the case of needing to charge multiple batteries simultaneously. Users need to operate multiple charging devices, which not only increases the complexity of the operation but also brings inconvenience to the management and maintenance of the charging devices. To solve this problem, a possible improvement has emerged in the market - a multi-battery charging system, which can charge multiple batteries simultaneously without the user having to operate each charging device separately. In related technologies, such multi-battery charging devices have a complex structure, which is a disassembled design and includes multiple components that need to be assembled, resulting in an increase in processing molds.

[0032] Refer to Figures 1-4 , Figures 1-4The figure shows a schematic diagram of the battery charging stand 1 in an embodiment of the present application. The battery charging stand 1 provided in an embodiment of the present application includes an integrally formed body 10. Optionally, the battery charging stand 1 is made of plastic, and the integrally formed process is injection molding in a mold. The plastic material of the battery charging stand 1 can be ABS (acrylonitrile butadiene styrene), PC (polycarbonate), LCP (liquid crystal polymer), HDPE (high density polyethylene), PP (polypropylene), etc.

[0033] As Figure 1 shown, the body 10 includes a base 200, a middle column 100, and at least two charging slots 300. The middle column 100 is provided on the base 200 and has at least two mounting surfaces. The charging slots 300 are formed by the base 200 and the middle column 100. Each charging slot 300 corresponds to each mounting surface. The charging slot 300 has an opening 310 facing the first direction X, and the opposite direction of the first direction X is defined as the direction in which the battery 2 is installed in the charging slot 300. Among them, the charging slot 300 includes a bottom wall 301 for supporting the battery 2. The base 200 is provided with a first groove 210, and the first groove 210 constitutes the bottom wall 301 of the charging slot 300. The first groove 210 is provided with a limiting portion for fitting the surface of the battery 2, and the limiting portion defines an installation area for installing the battery 2 on the first groove 210.

[0034] The battery 2 charging stand 1 can charge multiple batteries 2 separately, meeting the need for simultaneous charging of multiple batteries 2. At the same time, the charging efficiency is improved; the battery 2 charging device adopts an integrated processing method, and even if the structure is complex, it has the advantage of high-efficiency processing. The body 10 is an integral whole and does not require assembly, saving the setting of processing molds and reducing the production cost; the above-mentioned charging slot 300 is provided with a limiting portion to limit the laterally installed battery 2, and the limiting portion can match the shape of the battery 2. The battery 2 does not need to be provided with a special clamping structure, simplifying the structure of the battery 2 and the charging installation process.

[0035] The base 200 is trapezoidal, and the middle column 100 extends upward from the middle of the base 200. The circumferential side of the middle column 100 is the mounting surface, and each mounting surface corresponds to each charging slot 300. Multiple charging slots 300 are formed around the middle column 100. When the battery 2 is charged after installation, the outer surface of the battery 2 abuts against the middle column 100 and the base 200, and the charging slot 300 surrounds at least part of the outer surface of the battery 2 to abut and fix the battery 2, and the surface of the battery 2 that is not surrounded is used for the user to operate.

[0036] The seat body 200 is provided with a circuit board, and the circuit board is provided with components for controlling the charging function of the charging base 1 of the battery 2. The circuit board is electrically connected to the charging slot 300, and the circuit board is connected to an external power supply device through a power cord 201. The seat body 200 is provided with a through hole for the power cord 201 to extend out.

[0037] As Figure 3 , 4 shown, the charging slot 300 further includes a side wall 303 and a top wall 302. The battery 2 is installed in the charging slot 300 in a vertical side-mounted manner. The side-mounted is defined as that there is no displacement in the vertical direction during the installation process of the battery 2, but only rotation or translation in the horizontal direction. After installation, the longitudinal direction of the battery 2 has a top surface, a bottom surface and a side surface, corresponding to the top wall 302, the bottom wall 301 and the side wall 303 of the charging slot 300 respectively. Among them, the side wall 303 is arranged in a semi-surrounding manner around the side surface, and the top surface and the bottom surface can be in a fully surrounding shape or a semi-surrounding shape. Optionally, in this embodiment, the battery 2 is side-mounted by a rotating action. One side of the bottom surface of the battery 2 first contacts the bottom wall 301 (i.e., the first groove portion 210) of the charging slot 300, and then the battery 2 is operated so that the bottom surface moves to completely contact the first groove portion 210, and the docking with the first groove portion 210 is completed under the action of the limiting portion. At the same time, the top surface of the battery 2 also abuts against the top wall 302 in a matching manner.

[0038] The first groove portion 210 is a groove-shaped area formed by the seat body 200 recessing downward. The middle column 100 extends upward in this groove-shaped area. The outer edge of the first groove portion 210 is jointly surrounded by a part of the seat body 200 and a part of the middle column 100.

[0039] In one embodiment, the limiting portion includes a first limiting portion 220. The first limiting portion 220 protrudes from the first groove portion 210. The first limiting portion 220 defines the installation area so that the first limiting portion 220 abuts against the outer surface of the battery 2.

[0040] Specifically, the first limiting portion 220 protrudes from the side of the first groove portion 210 close to the side wall 303. In the Figure 1 , 2 shown embodiment, the first limiting portion 220 is arranged on both sides facing the slot opening 310 direction, corresponding to abut against the side surface of the battery 2, and limits the movement of the battery 2 in the third direction. The third direction is defined as the direction perpendicular to the first direction X. The shape of the installation area defined by the first limiting portion 220 on the bottom wall 301 is the same as the shape of the bottom surface of the battery 2. Optionally, the first limiting portion 220 and the outer edge of the first groove portion 210 jointly surround the installation area.

[0041] In one embodiment, the limiting portion includes a second limiting portion 230, the second limiting portion 230 is disposed on a side of the first groove portion 210 facing away from the middle column 100, the second limiting portion 230 and the first limiting portion 220 jointly define the installation area on the first groove portion 210, and the second limiting portion 230 is configured to abut against the outer surface of the battery 2 prior to the first limiting portion 220.

[0042] Specifically, the second limiting portion 230 protrudes from a side of the first groove portion 210 away from the side wall 303, that is, a side facing the first direction X. In Figure 1 the illustrated embodiment, the second limiting portion 230 is disposed below the notch 310, correspondingly abuts against the side surface of the battery 2, and restricts the movement of the battery 2 in the first direction X and provides pre-support. The shape of the installation area jointly defined by the second limiting portion 230 and the first limiting portion 220 on the bottom wall 301 is the same as the shape of the bottom surface of the battery 2. Optionally, the second limiting portion 230 and the first limiting portion 220 are spaced apart and have different shapes. Optionally, in this embodiment, when the battery 2 is installed and charged, the battery 2 is side-mounted with a rotational movement. One side of the bottom surface of the battery 2 first contacts the second limiting portion 230, and enters the first groove portion 210 by the limitation of the second limiting portion 230. The bottom surface of the battery 2 gradually contacts the bottom wall 301 of the charging groove 300, and then contacts the first limiting portion 220 to complete the matching between the first groove portion 210 and the battery 2.

[0043] In one embodiment, the surface of the second limiting portion 230 is inclined. The inclination direction is set towards the notch 310, that is, in the direction from the first groove portion 210 towards the outer edge of the first groove portion 210, the height of the second limiting portion 230 increases to guide the battery 2 into the first groove portion 210. The surface of the inclined second limiting portion 230 can be a flat inclined surface or a stepped surface.

[0044] In one embodiment, the limiting portion includes a third limiting portion 250, the third limiting portion 250 protrudes from the seat body 200 and is located at the outer edge of the notch 310 forming the first groove portion 210, and the position of the third limiting portion 250 is matched with the second limiting portion 230. The third limiting portion 250 can increase the support strength of the edge of the first groove portion 210 and play a role of over-supporting and guiding in the process of the side of the battery 2 entering the first groove portion 210 first during side mounting.

[0045] In one embodiment, the first groove portion 210 is provided with an elastic arm 240 integrated with the body 10, and the elastic arm 240 is configured to provide an elastic force towards the first direction X. The elastic arm 240 has a connecting end 241 and a free section 242. The free section 242 elastically deforms based on the connecting end 241, and a protrusion 243 is provided at the end of the free section 242, and the protrusion 243 is higher than the limiting portion.

[0046] Specifically, the elastic arm 240 is arranged in parallel with the limiting part, that is, the elastic arm 240 is arranged in the installation area. There is a gap between the free section 242 and the seat body 200 (i.e., the first groove part 210). An avoidance groove is formed on the first groove part 210 to accommodate the free end and prevent it from interfering with the deformation of the free end. The connecting end 241 is connected to the first groove part 210, so that the free section 242 undergoes elastic deformation based on the connecting end 241. In the natural state, the protrusion 243 protrudes from the bottom wall 301 of the charging groove 300, so that the protrusion 243 can sense the action of the battery 2 to drive the deformation of the free section 242. The elastic arm 240 buffers the installation of the battery 2, and the restoring force of the elastic arm 240 acts on the installed and charged battery 2 to ensure that the battery 2 is clamped tightly in the charging groove 300, making the battery 2 stable to pick up and convenient to install.

[0047] The protrusion 243 is arranged higher than the first limiting part 220. When the battery 2 enters the first groove part 210, the elastic arm 240 only needs to be stressed at the dimension part where the protrusion 243 is higher. When the deformation amount of the elastic arm 240 reaches the dimension where the protrusion 243 is higher, the first limiting part 220 contacts the surface of the battery 2 for limiting and shares the stress of the elastic arm 240.

[0048] In one embodiment, the deformation amplitude of the elastic arm 240 in the second direction Y is 0-1 mm, and the second direction Y is defined as the setting direction when the battery 2 is charged. That is, in the natural state, that is, when the battery 2 is not installed, the dimension by which the protrusion 243 is higher than the first limiting part 220 is 0-1 mm. Optionally, the dimension by which the protrusion 243 is higher than the first limiting part 220 is 0.1-0.8 mm, such as 0.5 mm, 0.55 mm, 0.6 mm, etc. When the dimension by which the protrusion 243 is higher than the first limiting part 220 is 0.5 mm, 0.55 mm, 0.6 mm, through tests, the elastic arm 240 can withstand at least 5000 presses without breaking.

[0049] In one embodiment, the first groove part 210 is provided with an elastic probe 400, and the elastic probe 400 is used for electrically connecting with the terminal of the battery 2. Specifically, the elastic probe 400 is arranged in parallel with the limiting part, that is, the elastic probe 400 is arranged in the installation area. The elastic probe 400 is located in the middle of the installation area, and the elastic arm 240 and the first limiting part 220 are arranged away from the elastic probe 400 in sequence.

[0050] Refer to Figures 6-7 , Figures 6-7 shows a schematic diagram of the elastic probe 400 for the charging seat 1 of the side-mounted battery 2 in an embodiment of the present application. The elastic probe 400 proposed by the present application also includes an installation shell 420, a needle head 410 and an elastic member 430. The elastic probe 400 is used for the electrical connection of the charging seat 1 of the battery 2, and is particularly suitable for the charging seat of the side-mounted battery 2.

[0051] The mounting shell 420 is disposed inside the charging base 1 of the battery 2. The mounting shell 420 has a hollow structure. An accommodation cavity 421 is provided inside the mounting shell 420. One end of the mounting shell 420 is provided with an opening, and the opening communicates the accommodation cavity 421 with the outside. The needle 410 can reciprocate relative to the mounting shell 420. The needle 410 includes a tail end 412 and a head end 411. The tail end 412 is disposed in the mounting shell 420, and the head end 411 extends out of the opening. An elastic member 430 is disposed in the mounting shell 420. One end of the elastic member 430 abuts against the needle 410 and is used to drive the needle 410 to reset. Wherein, in the natural state of the elastic probe 400, the ratio of the length of the head end 411 to the length of the tail end 412 is 0.8 - 1.6.

[0052] Compared with traditional elastic probes, within the range of the length of the head end 411 and the length of the tail end 412, the tail end 412 has a longer proportion, which ensures that when the needle 410 is laterally pressed, the connection strength and the anti-lateral stress strength of the needle 410 are improved, the swing angle thereof is reduced, thereby reducing the wear of the needle 410 and the mounting shell 420, and is applicable to the charging base with a side-mounted battery 2, and can withstand at least 2000 charges of the battery 2, avoiding the problems of frequent breakage, skew and failure.

[0053] The natural state of the elastic probe 400 is defined as the state when the whole elastic probe 400 is not affected by external forces. At this time, the part outside the mounting shell 420 is denoted as the head end 411, and the part inside the mounting shell 420 is denoted as the tail end 412. In one embodiment, in the natural state of the elastic probe 400, the ratio of the length of the head end 411 to the length of the tail end 412 is 1 - 1.5, that is, L1 / L2 is 1 - 1.5. Preferably, the ratio of the length of the head end 411 to the length of the tail end 412 is 1.21, 1.25. By way of example, the head size can be 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, and the length of the tail end 412 can be 1.8 mm, 1.9 mm, 2.0 mm, etc. After testing, when the ratio of the length of the head end 411 to the length of the tail end 412 is 1.21 (the head end 411 is 2.3 mm and the tail end 412 is 1.9 mm), the elastic probe 400 can withstand 5000 lateral pressures without breaking.

[0054] In one embodiment, the mounting shell 420 includes a shoulder 422 that is configured to match the tail portion. An inwardly tapered port portion 421, 421' is provided at the end of the shoulder 422 for limiting the tail portion within the mounting shell 420. Specifically, in match with the shoulder 422, the diameter of at least a part of the tail end 412 is greater than that of the head end 411. In the natural state of the elastic probe 400, the tail end 412 abuts against the port portion 421, 421' of the shoulder 422 under the action of the elastic member 430.

[0055] In one embodiment, the port portion 421, 421' is machined by CNC (Computer Numerical Control). As Figure 5 shown, the traditional processing technology for the port of the shoulder 422 is press riveting. The processing cost of the riveted port is relatively high, and a proprietary riveting machine is required for processing. Press riveting has strict requirements on the thickness of the sheet material (material thickness ≥ 1.0 mm). Therefore, for precision machining parts that require the use of thin materials (material thickness < 1.0 mm), the machining accuracy is insufficient, and the machining error leads to reduced strength. However, the CNC processing technology of the present application can improve the port strength, reduce the deformation amount when receiving side pressure, and the quality of the processed port is stable, the repeat accuracy is high, and the cost is saved.

[0056] In one embodiment, the tail end 412 includes a straight tail portion 4121 and a stepped tail portion 4122. In the natural state of the elastic probe 400, the straight tail portion 4121 corresponds to the shoulder 422, and the outer diameter of the straight tail portion 4121 is equal to that of the head end 411. The outer diameter of the stepped tail portion 4122 is greater than that of the head end 411.

[0057] Specifically, when the tail end 412 includes a straight tail portion 4121 and a stepped tail portion 4122, the port portion 421, 421' corresponds to the straight tail portion 4121 of the tail end 412. The shoulder 422 further includes a connecting portion corresponding to the stepped tail portion 4122. The inner diameter of the connecting portion is the same as the inner diameter of the receiving cavity 421, and the port portion 421, 421' is the same as the inner diameter of the opening. The straight tail portion 4121 has a length of at least 0.2 mm. Compared with the traditional press-riveted port with only the material thickness length (less than 0.1 mm), the length of this port is extended, thereby improving the anti-side stress ability of the end portion of the mounting shell 420.

[0058] In one embodiment, the ratio of the length of the port portions 421, 421' to the length of the head end 411 is 0.2 - 0.8, that is, L3 / L1 is 0.2 - 0.8. Preferably, the ratio of the length of the port portions 421, 421' to the length of the head end 411 is 0.4 - 0.8, and the ratios of the length of the port portions 421, 421' to the length of the head end 411 are 0.45, 0.59, and 0.70. By way of example, the head size can be 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, and the lengths of the port portions 421, 421' can be 1.20 mm, 1.36 mm, 1.45 mm, etc. After testing, when the ratio of the length of the port portions 421, 421' to the length of the head end 411 is 0.59 (the head end 411 is 2.3 mm and the tail end 412 is 1.36 mm), the elastic probe 400 can withstand 5000 lateral pressures without breaking.

[0059] In one embodiment, the distance (L4) between the outer surface of the needle 410 and the inner surface of the mounting shell 420 is less than 0.02 mm. When the needle 410 is subjected to lateral pressure, its movement space is reduced, thereby reducing its deformation amount when subjected to lateral pressure. Preferably, the distance between the outer surface of the needle 410 and the inner surface of the mounting shell 420 is 0.01 mm.

[0060] It can be understood that in the solution where the distance between the outer surface of the needle 410 and the inner surface of the mounting shell 420 is less than 0.02 mm and the solution where the ratio of the length of the port portions 421, 421' to the length of the head end 411 is 0.2 - 0.8, the ratio of the length of the head end 411 to the length of the tail end 412 can also exceed the range of 0.8 - 1.6 and still have a certain ability to resist lateral stress.

[0061] By way of example, the elastic probe 400 of the present application is improved based on the traditional pogopin probe structure. The pogopin probe can achieve synchronous transmission of current and signals, that is, the functions of charging and conducting electricity. The pogopin probe has a very small volume, so when applied in the battery charging base 1, it can reduce the overall weight, save space, beautify the product appearance, and is also easier to achieve sealing; the pogopin probe has smaller distributed capacitance and distributed inductance, with less loss, which is beneficial to the efficient transmission of high-frequency signals.

[0062] In one embodiment, the middle column 100 includes a second groove portion 110 extending along the second direction Y, the charging groove 300 includes side walls 303 and a top wall 302 that support the battery 2, the second groove portion 110 forms the side walls 303 and the top wall 302, and the top wall 302 and the bottom wall 301 respectively abut against both ends of the battery 2.

[0063] Specifically, the second groove 110 is connected to the first groove 210, the side wall 303 corresponds to the side of the battery 2, and the side wall 303 is semi-enclosed at the side, and part of the side of the battery 2 can be exposed in the groove 310. A platform 130 is provided at one end of the center column 100 away from the base 200, and the platform 130 forms a top wall 302 against the top surface of the battery 2. After the battery 2 is installed and charged, the battery 2 is located between the platform 130 and the base 200. The area of ​​the top wall 302 is smaller than the area of ​​the top surface of the battery 2, so that the second groove 110 is semi-enclosed as a whole.

[0064] In one embodiment, a limiting rib 120 is convexly provided on the side of the second groove portion 110 away from the seat body 200, and the limiting rib 120 is used to abut against the outer surface of the battery 2. Specifically, the portion of the second groove portion 110 that forms the top wall 302 is convexly provided with a limiting rib 120, and similar to the limiting portion, the limiting rib 120 also forms an installation area that matches the shape of the battery 2, so as to receive the side-mounted battery 2 and limit it. The limiting rib 120 can also be directly set against the top surface of the battery 2 to assist the elastic arm 240 in supporting the top surface of the battery 2.

[0065] In one embodiment, a notch 121 is provided at one end of the limiting rib 120 facing the first direction X. The notch 121 is arranged in an inclined surface, and when most of the bottom surface of the battery 2 enters the first groove 210 , the notch 121 can guide the top surface of the battery 2 to enter the second groove 110 .
