Description

Technical Field

[0001] This invention relates to the field of exoskeleton robot technology, specifically to a magnetically positioned, quick-release exoskeleton battery structure and assembly method. Background Technology

[0002] As wearable devices that enhance human mobility, exoskeleton devices require batteries that meet core requirements such as rapid energy exchange, precise docking, and stable power supply. Existing exoskeleton batteries generally suffer from the following defects: The use of bolt or snap-fit ​​connections requires tools or manual operation for disassembly and assembly, resulting in low energy conversion efficiency and inability to meet the emergency energy replenishment needs at the mission site. The lack of a precise positioning structure makes it easy for the battery to shift when docking with the exoskeleton, resulting in poor contact of the power supply contacts and interruption of BMS communication. The lack of foolproof design means that reverse assembly can easily damage the BMS protection board and conductive contacts, posing a safety hazard. Insufficient connection strength can cause batteries to loosen or even fall off during vigorous exoskeleton movements, affecting the reliability of the equipment.

[0003] The shortcomings of existing exoskeleton battery structures are: 1. Patent document CN219819780U discloses a power module for an assistive exoskeleton and the assistive exoskeleton itself. "This disclosure relates to a power module for an assistive exoskeleton and the assistive exoskeleton itself. The power module includes an electronic control box and a mobile battery. The electronic control box has a battery receiving slot, and the mobile battery is movably inserted into the battery receiving slot along the opening direction of the battery receiving slot. The end of the mobile battery has a locking structure for movably engaging with the electronic control box. This disclosure, by providing a battery receiving slot for accommodating the mobile battery, and simultaneously utilizing the locking structure to movably engage with the electronic control box after the mobile battery is inserted and accommodated, enables control of the mobile battery..." The battery is fixed in place to prevent accidental battery loss during transport and use of the power exoskeleton. The movable locking mechanism allows for easy assembly and disassembly, enabling battery replacement without removing the exoskeleton, thus improving convenience and user experience. However, the aforementioned document states that the movable battery is only fixed in one direction via a locking structure. During vigorous activity, the latch is prone to displacement or even disengagement due to vibration, resulting in insufficient connection strength. Furthermore, the insertion end of the movable battery lacks guidance and foolproof design, making it easy for users to insert it incorrectly or misalign the contacts, leading to poor power supply contact. Summary of the Invention

[0004] The purpose of this invention is to provide a magnetically positioned and quick-release exoskeleton battery structure and assembly method, which achieves integrated optimization of precise magnetic positioning, strong anti-detachment, one-click quick release, and foolproof protection, and is suitable for high-frequency movement conditions of exoskeletons.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a magnetically positioned, quick-release exoskeleton battery structure, comprising: The plastic lower shell has an internal cavity, and a limiting structure and a magnetic limiting groove are provided on one side of the cavity. The BMS protection board is electrically connected to the 6S1P battery pack semi-finished product by spot welding with nickel sheets, and is fixed in the receiving cavity by adhesive. The adapter plate is fixed to the lower plastic shell by the limiting structure, and is used to establish an electrical connection between the 6S1P battery pack semi-finished product and the exoskeleton device. FR4 epoxy board, with a thickness of 0.8mm-1.2mm, is assembled onto the lower plastic shell and covers the magnet limiting groove to limit the magnet within the magnet limiting groove; The upper plastic shell is detachably and fixedly connected to the lower plastic shell by bolts and buckles, and encapsulates the above components inside; The outer surface of the plastic upper shell is provided with a foolproof structure for one-way matching assembly with the exoskeleton device. The magnet is used to provide a magnetic attraction force of 15N-30N to achieve automatic positioning and engagement. The magnet is axially magnetized, and its magnetization direction matches the magnetic pole of the corresponding magnet or ferromagnetic component on the side of the exoskeleton device.

[0006] Preferably, the limiting structure includes a first limiting structure for fixing the BMS protection board and a second limiting structure for fixing the adapter board.

[0007] Preferably, the foolproof structure includes a groove on the top of the plastic upper shell, double sliding grooves on the opposite side of the top of the plastic upper shell, and a foolproof protrusion on one end of the plastic upper shell. The groove, double sliding grooves, and foolproof protrusion together constitute a multi-feature combination foolproof structure. The groove and the protruding rib on the exoskeleton device interface are in clearance fit, with a clearance of 0.1mm-0.3mm. The double sliding groove and the double guide rails on the exoskeleton device interface are in transition fit. The foolproof protrusion and the recess at the end of the exoskeleton device interface are in interference fit, with an interference of 0.05mm-0.1mm. After the three are combined, any misfit during reverse assembly will result in failure to insert.

[0008] Preferably, the adapter plate is fixed by the snap-fit ​​engagement of the limiting structure.

[0009] Preferably, the buckle structure is an elastic buckle, and the elastic buckle and the bolt together form a double fixation.

[0010] Preferably, there are four bolts, which are threaded onto the four corners of the lower plastic shell.

[0011] An assembly method for a magnetically positioned and quick-release exoskeleton battery structure is provided, as follows: S1. The 6S1P battery pack semi-finished product is electrically connected to the BMS protection board by spot welding with nickel sheets to form a battery protection component. The internal resistance of a single weld point after spot welding is ≤5mΩ. S2. Fix the battery protection component to the receiving cavity of the plastic lower shell by applying structural adhesive, wherein the structural adhesive is acrylic structural adhesive and the curing time is ≥30min; S3. The adapter plate is snapped and fixed by the limiting structure of the lower plastic shell; S4. Assemble the magnet into the magnet limiting groove of the plastic lower shell; S5. Assemble the FR4 epoxy board onto the lower plastic shell to cover the magnet limiting groove and fix the magnet in place. S6. The upper plastic shell is fixedly connected to the lower plastic shell by bolts around the perimeter and a snap-fit ​​structure in the middle, thus completing the assembly of the battery structure.

[0012] Preferably, after step S6, the assembly of the battery structure is further followed by a step of unidirectionally matching the assembled battery structure with the exoskeleton device's interface through the anti-foolproof structure on the outer surface of the plastic upper shell.

[0013] Preferably, the magnet provides a magnetic attraction force of 15N-30N when the exoskeleton battery structure is close to the main interface, so as to achieve automatic and precise positioning, attraction and electrical connection.

[0014] Preferably, in step S6, the snap-fit ​​structure is located in the middle region between the upper plastic shell and the lower plastic shell.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides an attraction force of 15N-30N through magnets, enabling rapid and precise positioning and attraction between the battery and the exoskeleton device. No tools are required, and it can be operated with one hand, significantly improving energy conversion efficiency. The measured energy conversion time is ≤5s. The axial magnetization and magnetic pole matching design ensure the directionality and stability of the magnetic attraction force. 2. This invention employs a multi-feature combination anti-misfit structure, namely groove, double sliding groove and anti-misfit protrusion, and optimizes the fit tolerance, namely clearance fit, transition fit and interference fit, so that any misfit during reverse assembly will result in failure to insert. After 1000 reverse assembly tests, the misassembly rate is 0, which can effectively prevent reverse assembly and avoid damage to the BMS protection board and conductive contacts. 3. The present invention uses a double fixing structure of bolts and intermediate buckles between the plastic upper shell and the plastic lower shell, which not only ensures the connection strength of the battery structure, but also facilitates maintenance and replacement. 4. By limiting the thickness of the FR4 epoxy board to 0.8mm-1.2mm, this invention balances insulation strength and structural compactness. Process parameters such as spot welding internal resistance ≤5mΩ, acrylic structural adhesive and curing time ≥30min ensure the reliability and consistency of the battery pack. The overall structure is compact, with high space utilization and simple assembly, and can be widely used in battery assembly of various exoskeleton devices. Attached Figure Description

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Example 1: Please refer to Figure 1 and Figure 2 The present invention provides a magnetic positioning quick-release exoskeleton battery structure, including a plastic lower shell 1, a plastic upper shell 9, a BMS protection board 4, an adapter board 6, an FR4 epoxy board 7, a magnet 8, and a 6S1P battery pack semi-finished product 5. The plastic lower shell 1 has a receiving cavity 2 inside. A first limiting structure 13, a second limiting structure 14 and a magnetic limiting groove 3 are provided on one side of the receiving cavity 2. The first limiting structure 13 is used to fix the BMS protection plate 4, the second limiting structure 14 is used to fix the adapter plate 6, and a magnet 8 is provided in the magnetic limiting groove 3. The 6S1P battery pack semi-finished product 5 is electrically connected to the BMS protection board 4 by spot welding with nickel sheets, and then fixed in the receiving cavity 2 of the plastic lower shell 1 by structural adhesive. The adapter plate 6 is fixed to the plastic lower shell 1 by the snap-fit ​​of the second limiting structure 14, which is used to establish the electrical connection between the 6S1P battery pack semi-finished product 5 and the exoskeleton device. The thickness of the FR4 epoxy board 7 is 0.8mm-1.2mm, preferably 1.0mm. It is assembled on the plastic lower shell 1 and covers the magnet limiting groove 3, thereby axially limiting the magnet 8 in the magnet limiting groove 3 and preventing the magnet 8 from falling off. The plastic upper shell 9 is detachably and fixedly connected to the plastic lower shell 1 by four bolts 10 located at the four corners of the plastic lower shell 1 and a buckle structure 11 located in the middle area. The buckle structure 11 is preferably an elastic buckle, which together with the bolts 10 forms a double fixation. The plastic upper shell 9 encapsulates the BMS protection board 4, the adapter board 6, the FR4 epoxy board 7, the magnet 8 and the 6S1P battery pack semi-finished product 5 inside. The outer surface of the plastic upper shell 9 is provided with a foolproof structure 12. The foolproof structure 12 includes a groove 15 on the top of the plastic upper shell 9, a double sliding groove 16 on the opposite side of the top of the plastic upper shell 9, and a foolproof protrusion 17 on one end of the plastic upper shell 9. The groove 15, the double sliding groove 16 and the foolproof protrusion 17 together constitute a multi-feature combination foolproof structure 12, which is used to achieve one-way matching and assembly with the whole machine interface of the exoskeleton device to prevent reverse insertion. Magnet 8 is a neodymium magnet, axially magnetized, and its magnetization direction matches the magnetic poles of the corresponding magnet or ferromagnetic component on the side of the exoskeleton device (e.g., like poles facing each other or unlike poles facing each other) to generate a magnetic attraction force of 15N-30N. Tests have shown that the attraction force range of 15N-30N can ensure that the battery does not loosen when the exoskeleton is moving violently, while allowing the operator to easily pull it out with one hand without tools. When the assembled battery structure approaches the interface of the exoskeleton device, magnet 8 generates magnetic attraction, automatically pulling the battery structure to the correct position to achieve precise positioning and engagement. At the same time, the adapter plate 6 is reliably connected to the contacts of the exoskeleton device to complete power supply and communication. During disassembly, simply overcome the magnetic attraction to pull out the battery; no tools are required, enabling rapid energy exchange.

[0022] Example 2: Please refer to Figure 3 The present invention provides an assembly method for a magnetically positioned, quick-release exoskeleton battery structure, comprising the following steps: S1: The 6S1P battery pack semi-finished product 5 is electrically connected to the BMS protection board 4 by spot welding with nickel sheets to form a battery protection component. After spot welding, the internal resistance of a single weld point is measured with a milliohm meter. It is required to be ≤5mΩ, otherwise it needs to be re-welded. S2: Fix the battery protection component to the receiving cavity 2 of the plastic lower shell 1 by applying structural adhesive. The structural adhesive is an acrylic structural adhesive (such as 3M DP460). After application, it is cured at room temperature for ≥30 minutes, or heated to 60℃ for 15 minutes to ensure the bonding strength. S3: The adapter plate 6 is snapped and fixed by the second limiting structure 14 of the plastic lower shell 1. The electrical interface direction of the adapter plate 6 should be consistent with the contact direction of the subsequent exoskeleton device. S4: Assemble the magnet 8 into the magnet limiting groove 3 of the plastic lower shell 1. The magnetization direction of the magnet 8 should match the corresponding magnet or ferromagnetic component on the exoskeleton device. S5: Assemble the FR4 epoxy board 7 onto the plastic lower shell 1 to cover the magnet limiting groove 3, so as to limit and fix the magnet 8. S6: The plastic upper shell 9 is fixedly connected to the plastic lower shell 1 through the bolts 10 around the perimeter and the buckle structure 11 in the middle area to complete the assembly of the battery structure. First, snap the middle elastic buckle, and then tighten the screws at the four corners to ensure sealing and structural strength. After assembly, the battery structure is matched unidirectionally with the interface of the exoskeleton device through the foolproof structure 12 on the outer surface of the plastic upper shell 9. Due to the unidirectional nature of the foolproof structure 12, only batteries in the correct orientation can be inserted into the interface. When the battery approaches the interface, the magnet 8 generates a magnetic attraction force of 15N-30N, automatically attracting the battery to the precise position. At the same time, the contacts on the adapter plate 6 are electrically connected to the exoskeleton device.

[0023] Example 3: Please refer to Figure 1 and Figure 2 The present invention provides a magnetically positioned quick-release exoskeleton battery structure: the foolproof structure 12 is described in further detail; The foolproof structure 12 includes three features: groove 15, double sliding groove 16, and foolproof protrusion 17. The groove 15 is located on one side edge of the top of the plastic upper shell 9 and is rectangular in shape. It is used to cooperate with the corresponding protrusion on the interface of the exoskeleton device. When the battery is in the correct direction, the protrusion can slide into the groove 15. When the battery is reversed, the protrusion and the groove 15 are misaligned and cannot be inserted. The double slide groove 16 is located on the top of the plastic upper shell 9 on the opposite side of the groove 15. It consists of two parallel and spaced slide grooves and is used to cooperate with the double guide rails on the interface of the exoskeleton device to provide bidirectional guidance and ensure that the battery slides in along the correct trajectory. The anti-fooling protrusion 17 is located at one end of the plastic upper shell 9 and is in the shape of a triangle or trapezoid. It is used to cooperate with the corresponding recess at the end of the interface of the exoskeleton device. When the battery is in the correct direction, the anti-fooling protrusion 17 is inserted into the recess. When the battery is reversed, the anti-fooling protrusion 17 is misaligned with the recess, preventing the battery from being inserted further. In this embodiment, the groove 15 and the protruding rib on the exoskeleton device interface are in a clearance fit, with the clearance controlled at 0.1mm-0.3mm to ensure smooth guidance and no obvious shaking. The double slide groove 16 and the double guide rail on the exoskeleton device interface are in a transition fit (maximum clearance 0.02mm, maximum interference 0.01mm) to ensure a smooth and unobstructed sliding process. The anti-fooling protrusion 17 and the recess at the end of the exoskeleton device interface are in an interference fit, with an interference amount of 0.05mm-0.1mm. When the battery is in the correct orientation, the anti-fooling protrusion 17 can be inserted into the recess with slight pressure, providing a clear sense of positioning. When the battery is reversed, due to the misalignment of the protrusion and the recess, the protrusion will interfere with the device plane, preventing further insertion. After the combination of the three, any misfit during reverse assembly will result in failure to insert. After 1000 reverse assembly tests, 1000 were correctly assembled and 1000 were reverse assembled. During the 1000 reverse assembly tests, insertion failed, resulting in a misassembly rate of 0.

[0024] Example 4: Please refer to Figure 2 The present invention provides a magnetically positioned quick-release exoskeleton battery structure: the fixing method of the magnet 8 is described in detail; The bottom of the plastic lower shell 1 is provided with a magnet limiting groove 3. The magnet limiting groove 3 is a circular recess, and its depth matches the thickness of the magnet 8, generally 80%-100% of the thickness of the magnet 8, so as to ensure that the magnet 8 protrudes slightly or is flush with the surface after it is installed. Magnet 8 is a neodymium magnet, and its surface can be coated with a three-layer nickel-copper-nickel plating to prevent oxidation and corrosion. Magnet 8 is magnetized along the thickness direction (axial direction) to ensure that it presents the correct magnetic pole direction to the outside. An FR4 epoxy board 7 covers the magnet limiting groove 3, with a thickness of 0.8mm-1.2mm, preferably 1.0mm. The FR4 epoxy board 7 is fixed by a mounting groove in the plastic lower shell 1, and the mounting groove is located at one end of the magnet limiting groove 3. Thus, the FR4 epoxy board 7 axially limits the magnet 8 in the magnet limiting groove 3, preventing the magnet 8 from falling off when subjected to external impact.

[0025] Example 5: Please refer to Figure 2 The present invention provides a magnetically positioned quick-release exoskeleton battery structure: the double fixing structure between the plastic upper shell 9 and the plastic lower shell 1 is described in detail. The plastic upper shell 9 and the plastic lower shell 1 are fixed in two ways: one is by four bolts 10 located at the four corners of the plastic lower shell 1 with threaded connection, and the other is by the snap-fit ​​connection of the buckle structure 11 located in the middle area. The threaded sections of the four bolts 10 are respectively threaded to the mounting posts with internal threads at the four corners of the lower plastic shell 1. The upper plastic shell 9 has through holes at the corresponding positions. By providing the bolt head structure at the corresponding positions, a tension force perpendicular to the mating surface is provided to ensure the tight fit and sealing of the upper and lower shells. The snap-fit ​​structure 11 is located in the middle area of ​​the lower plastic shell 1. Specifically, it includes an elastic hook on the lower plastic shell 1 and a slot on the upper plastic shell 9. The elastic hook is a cantilever beam structure with a barb at its end. When the upper plastic shell 9 and the lower plastic shell 1 are snapped together, the elastic hook first undergoes elastic deformation. After the barb slides into the slot, it resets and achieves snap-fit ​​locking. The snap-fit ​​structure 11 provides quick initial fixation, which is convenient for subsequent tightening of the bolts 10. During disassembly, first loosen the bolts 10 at the four corners, then pull open the plastic upper shell 9 with force to disengage the elastic hooks from the slots. The double fixing structure ensures the structural connection strength and facilitates assembly, disassembly and maintenance.

[0026] Example 6: A magnetically positioned quick-release exoskeleton battery structure provided by the present invention: The performance of the assembled exoskeleton battery structure is tested and compared with the prior art; Test samples: 10 battery structure samples of the present invention and 10 prior art control samples (exoskeleton batteries with bolt connections); Test method: Transformation time test: Ten testers performed battery disassembly and replacement operations, with each person repeating the operation 10 times. The total time from the start of disassembly to the completion of the installation of the new battery and the establishment of electrical connection was recorded. Dropping rate test: The battery is installed on the exoskeleton device, and vibration simulating the violent movement of the exoskeleton is applied on the vibration table (frequency sweep of 5-20Hz, acceleration of 2g). Each sample is cycled 100 times, and the number of times the battery becomes loose or falls off is recorded. Misassembly rate test: Ten testers performed battery assembly under blind operation conditions (obstructed vision), with each person repeating 100 times, and the number of times the battery was successfully inserted in reverse was recorded (i.e., the number of misassemblies). Table 1 Test Results

[0027] The average transduction time of this invention is 3.2s-4.8s, which is significantly better than the 30s-60s of the prior art, and the efficiency is improved by about 6-10 times. In the vibration test, the magnetic positioning structure of this invention (15N-30N magnetic force combined with double fixation) did not fall off in 100 cycles, while the fall-off rate of the prior art reached 12%-18%, indicating that the anti-vibration and anti-fall-off effect of this invention is significantly better than that of the prior art. In the misassembly rate test, this invention achieved a 0 misassembly rate through the multi-feature combination anti-misfit structure 12, while the misassembly rate of the prior art with a single anti-misfit feature reached 15%-25%.

[0028] Working principle: Magnet 8 provides an attraction force of 15N-30N, enabling rapid and precise positioning and engagement of the battery and exoskeleton device. No tools are required; operation can be done with one hand, significantly improving energy conversion efficiency. Actual energy conversion time is ≤5s. Axial magnetization and magnetic pole matching design ensure the directionality and stability of the magnetic attraction force. A multi-feature combination anti-foolproof structure 12, namely groove 15, double sliding groove 16, and anti-foolproof protrusion 17, combined with optimized fit tolerances (clearance, transition, and interference fit), ensures that any part of the fit is correct even during reverse assembly. Incorrect assembly will prevent insertion, effectively preventing reverse assembly and avoiding damage to the BMS protection board 4 and conductive contacts. The plastic upper shell 9 and the plastic lower shell 1 are double-fixed by bolts 10 and intermediate buckles, which ensures structural strength and facilitates maintenance and replacement. The thickness of the FR4 epoxy board 7 is limited to 0.8mm-1.2mm, which takes into account both insulation strength and structural compactness. Process parameters such as spot welding internal resistance ≤5mΩ, acrylic structural adhesive and curing time ≥30min ensure the reliability and consistency of the battery pack.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
