Description

Technical Field

[0001] This utility model relates to the field of robot battery technology, specifically to a quick-release battery structure, a battery pack, and a robot. Background Technology

[0002] As the core energy component of a robot, the installation method of the battery directly affects the robot's ease of use and operational reliability. Currently, robot battery installation methods are mainly divided into two types: built-in and removable.

[0003] In removable robot battery designs, a common structural design involves opposing sliders that engage with a retaining groove. However, when the robot tip over or undergoes violent movement, the sliders may disengage from the retaining groove due to inertia or external impact, causing the battery to accidentally fall out. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release battery structure, a battery pack, and a robot, which can prevent the battery from coming off the robot body during violent movements or falls, improve the stability and reliability of battery installation, and enable quick installation and removal of the battery.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In a first aspect, this utility model provides a quick-release battery structure, comprising:

[0007] Battery sealing plate;

[0008] A battery locking assembly includes locking sliders, a first elastic element, and a sliding limiting mechanism. Two locking sliders are slidably disposed on the battery sealing plate. One end of the first elastic element abuts against the opposite side of the locking sliders, so that the locking sliders tend to slide out of the battery sealing plate. The sliding limiting mechanism is used to limit the sliding direction and stroke of the locking sliders, so that the locking sliders slide out of the battery sealing plate in opposite directions or slide back into the battery sealing plate in opposite directions.

[0009] A locking stop assembly is disposed on the battery locking assembly. The locking stop assembly has a locked state and an unlocked state. In the locked state, the locking stop assembly prevents the locking slider protruding from the battery cover from retracting. In the unlocked state, the locking stop assembly unlocks so that the locking slider can retract into the battery cover.

[0010] In an optional embodiment, the sliding limiting mechanism includes a guide post, which is fixedly disposed on the battery sealing plate, and the locking slider is provided with a guide groove that cooperates with the guide post.

[0011] In an optional embodiment, the sliding limiting mechanism includes a limiting clamp, which is fixedly disposed on the battery sealing plate, and the locking slider passes through the limiting clamp.

[0012] In an optional embodiment, the sliding limiting mechanism further includes a slider positioning seat, which is fixedly disposed on the battery sealing plate, and the two ends of the first elastic member abut against the locking slider and the slider positioning seat respectively.

[0013] In an optional embodiment, the first elastic element is a compression spring, the slider positioning seat is provided with a first compression spring mounting part, the locking slider is provided with a second compression spring mounting part, and the two ends of the compression spring are respectively sleeved on the first compression spring mounting part and the second compression spring mounting part.

[0014] In an optional embodiment, the locking stop assembly includes a rotary handle, a cover, and a second elastic element. One end of the rotary handle is hinged to the locking slider, and the hinged end of the rotary handle is also connected to the second elastic element. The other end of the rotary handle is provided with a stop portion. The cover is fitted onto the battery locking assembly and fixedly connected to the battery sealing plate. The cover has a slot. The rotary handle rotates relative to the locking slider to screw into or out of the slot. A stop groove is provided in the slot. When the rotary handle is screwed into the slot, the stop portion engages with the stop groove to prevent the locking slider protruding from the battery sealing plate from retracting.

[0015] In an optional embodiment, each of the two locking sliders is hinged with a rotating handle, and the second elastic element is a tension spring, with both ends of the tension spring connected to the hinge ends of the two rotating handles respectively.

[0016] In an optional embodiment, a limiting pin is fixed to the end of the rotary handle away from the stop portion, and the two ends of the tension spring are respectively sleeved on the limiting pins of the two rotary handles.

[0017] In an optional embodiment, when the rotating handle is screwed into the slot, the rotating handle is parallel to the plane of the battery sealing plate, and the hinge axis between the rotating handle and the locking slider is higher than the connection position between the rotating handle and the second elastic element.

[0018] In an optional embodiment, the cover has openings at both ends, through which the locking slider protrudes or retracts into the battery cover.

[0019] In an optional embodiment, the locking stop assembly includes a sliding switch disposed between the two locking sliders. One end of the sliding switch is provided with a sliding limit block. The sliding switch slides in a direction perpendicular to the sliding direction of the locking sliders, so that the sliding limit block slides into the space between the two locking sliders to prevent the locking sliders protruding from the battery cover from retracting, or slides out from the space between the two locking sliders so that the locking sliders can retract into the battery cover.

[0020] In an optional embodiment, the end of the sliding switch away from the sliding limit block is further provided with an elastic buckle. The elastic buckle has elastic protrusions fixed on both sides. The sliding switch slides to move the elastic buckle from one end of the elastic protrusion to the other end of the elastic protrusion. The distance between the elastic protrusions is less than the width of the elastic buckle.

[0021] Secondly, this utility model provides a battery pack, including the quick-release battery structure described in any of the foregoing embodiments, and further including a housing and a battery module, wherein the battery module is disposed inside the housing, and the battery sealing plate closes the housing.

[0022] Thirdly, this utility model provides a robot including the battery pack described in the foregoing embodiments. The robot is provided with a cavity for installing the battery pack, and the cavity is provided with a locking slot. When the battery pack is installed in the cavity, the locking slider protrudes from the battery sealing plate and enters the locking slot.

[0023] The beneficial effects of the quick-release battery structure, battery pack, and robot provided by this utility model embodiment include:

[0024] This utility model discloses a quick-release battery structure comprising a battery sealing plate, a battery locking assembly, and a locking stop assembly. The battery locking assembly includes locking sliders, a first elastic element, and a sliding limiting mechanism. Two locking sliders are slidably mounted on the battery sealing plate. One end of the first elastic element abuts against the opposite side of the locking sliders. The sliding limiting mechanism limits the sliding direction and stroke of the locking sliders, allowing them to slide out of the battery sealing plate in opposite directions or retract into the battery sealing plate in opposite directions. The locking stop assembly is disposed on the battery locking assembly. The locking stop assembly has a locked state and an unlocked state. In the locked state, the locking stop assembly prevents the locking sliders protruding from the battery sealing plate from retracting. In the unlocked state, the locking stop assembly unlocks to allow the locking sliders to retract into the battery sealing plate. The battery pack includes a quick-release battery structure, a housing, and a battery module. The battery module is disposed within the housing. The battery sealing plate closes the housing. The robot includes a battery pack. The robot has a cavity for mounting the battery pack. A locking slot is provided on the cavity. With the battery pack installed inside the cavity, the locking slider protrudes from the battery sealing plate and enters the locking slot. By setting the locking slider to protrude from the battery sealing plate and enter the locking slot, the battery pack can be locked inside the cavity, securing the battery pack. A locking stop assembly prevents the locking slider from retracting, preventing the battery pack from detaching from the robot in special circumstances. This invention prevents the battery from detaching from the robot body during violent movements or falls, improving the stability and reliability of battery installation and enabling rapid battery installation and removal.

[0048] The following describes in detail the overall structure, working principle, and technical effects of the quick-release battery structure and battery pack provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0049] First Embodiment

[0050] Please refer to Figures 1-3 This embodiment provides a battery pack 1000 for use in robots.

[0051] The battery pack 1000 includes a housing 200, a battery module 300, and a quick-release structure 100. The battery module 300 is disposed within the housing 200. The quick-release structure 100 includes a battery sealing plate 10, a battery locking assembly 20, and a locking stop assembly 30. The battery sealing plate 10 is used to close the housing 200. It is understood that the battery module 300 is installed inside the housing 200, and then the battery sealing plate 10 is placed on top of the housing 200 and fixed to the housing 200 by screws, thereby closing the housing 200 and securing the internal battery module 300. The battery locking assembly 20 and the locking stop assembly 30 are disposed on the outside of the housing 200.

[0052] Specifically, in this embodiment, the housing 200 is further provided with a charging interface 201 and a discharging interface 202. After the battery module 300 is installed in the housing 200, the battery module 300 is connected to the charging interface 201 and the discharging interface 202 by bonding wires. The charging interface 201 and the discharging interface 202 are respectively fixed to the housing 200 by screws for charging and discharging the battery module 300.

[0053] In this embodiment, the battery cover 10 is a battery top cover, and the battery cover 10 is disposed above the housing 200. In other embodiments, the battery cover 10 may be configured as a side plate or bottom plate of the battery pack 1000, and this utility model does not limit this.

[0054] Please refer to Figure 2 , Figure 4 and Figure 5 Furthermore, the battery locking assembly 20 is used to secure the battery pack 1000. The battery locking assembly 20 includes locking sliders 21, a first elastic member, and a sliding limiting mechanism. Two locking sliders 21 are slidably disposed on the battery cover plate 10. One end of the first elastic member abuts against the opposite side of the locking sliders 21, causing the locking sliders 21 to tend to slide out of the battery cover plate 10. The sliding limiting mechanism is used to limit the sliding direction and stroke of the locking sliders 21, so that the locking sliders 21 slide out of the battery cover plate 10 in opposite directions, or slide back into the battery cover plate 10 in opposite directions.

[0055] It is understood that on the battery cover plate 10, two locking sliders 21 are slidably disposed in the same direction. The two locking sliders 21 can move closer to each other so that the ends of the locking sliders 21 retract into the battery cover plate 10; the two locking sliders 21 can also move further apart so that the ends of the locking sliders 21 protrude beyond the battery cover plate 10. It should be noted that the ends of the locking sliders 21 protruding beyond the battery cover plate 10 means that the ends of the locking sliders 21 protrude beyond the battery pack 1000. In this embodiment, the battery cover plate 10 covers the housing 200, and the locking sliders 21 protrude beyond the battery cover plate 10, that is, the locking sliders 21 protrude beyond the side wall of the housing 200, which is to say, protrudes beyond the battery pack 1000. It is understood that the battery pack 1000 is installed in the cavity, and the portion of the locking sliders 21 protruding beyond the battery cover plate 10 engages with the locking slots in the cavity to fix the battery pack 1000 in the cavity.

[0056] By setting the first elastic element, the locking slider 21 is given a tendency to move towards the outside of the battery cover plate 10, so that the locking slider 21 always protrudes from the battery cover plate 10 without the action of external force, thus maintaining the battery pack 1000 in a fixed state.

[0057] By setting a sliding limit mechanism, the sliding direction and stroke of the locking slider 21 are limited to prevent the locking slider 21 from deviating or falling off.

[0058] Please refer to Figure 5 and Figure 6 Specifically, the sliding limiting mechanism includes a guide post 11. The guide post 11 is fixedly mounted on the battery sealing plate 10. A guide groove 211, which mates with the guide post 11, is provided on the locking slider 21. In this embodiment, the guide groove 211 is a strip-shaped groove along the sliding direction of the locking slider 21. The outer diameter of the guide post 11 matches the width of the guide groove 211, allowing the guide post 11 to insert into the guide groove 211. When the locking slider 21 slides relative to the battery sealing plate 10, the guide post 11 slides relative to the battery sealing plate 10. By configuring the guide post 11 and the guide groove 211 to mate, the locking slider 21 has a maximum stroke that allows it to retract or protrude beyond the battery sealing plate 10. It is understood that when the guide post 11 abuts against the two end sidewalls of the guide groove 211, the locking slider 21 cannot continue to slide.

[0059] Please refer to Figure 4 and Figure 5 The sliding limiting mechanism also includes a limiting clamp 23. The limiting clamp 23 is fixedly mounted on the battery cover plate 10. The locking slider 21 passes through the limiting clamp 23. Specifically, both ends of the limiting clamp 23 are fixedly connected to the battery cover plate 10. The limiting clamp 23 has an arched structure, which clamps the locking slider 21 onto the battery cover plate 10 to restrict the locking slider 21 to have only one degree of freedom in the plane of the battery cover plate 10, so that the locking slider 21 can only slide in one direction.

[0060] Furthermore, the sliding limiting mechanism includes a slider positioning seat 24. The slider positioning seat 24 is fixedly mounted on the battery sealing plate 10. The two ends of the first elastic member abut against the locking slider 21 and the slider positioning seat 24, respectively. Specifically, the slider positioning seat 24 presses the locking slider 21 onto the battery sealing plate 10 to restrict the degree of freedom of the locking slider 21 perpendicular to the battery sealing plate 10.

[0061] Please refer to Figure 5 and Figure 7 Specifically, in this embodiment, the first elastic element is a compression spring 22. A first compression spring mounting portion 241 is provided on the slider positioning seat 24. A second compression spring mounting portion 212 is provided on the locking slider 21. Both ends of the compression spring 22 are respectively sleeved on the first compression spring mounting portion 241 and the second compression spring mounting portion 212. Specifically, the first compression spring mounting portion 241 and the second compression spring mounting portion 212 are opposing columnar structures, and both ends of the compression spring 22 are respectively sleeved on the first compression spring mounting portion 241 and the second compression spring mounting portion 212 to prevent the compression spring 22 from disengaging from the slider positioning seat 24 and the locking slider 21.

[0062] In this embodiment, the slider positioning seat 24 is disposed at the ends of the two locking sliders 21 that are close to each other. In this embodiment, four compression springs 22 are provided, with one compression spring 22 disposed on each side of each locking slider 21 perpendicular to its sliding direction. In other embodiments, the number and installation position of the compression springs 22 can be set as needed, and this utility model does not limit them.

[0063] Please refer to Figures 8-10 In this embodiment, the locking stop assembly 30 includes a rotating handle 31, a cover 33, and a second elastic member. One end of the rotating handle 31 is hinged to the locking slider 21. The end of the rotating handle 31 hinged to the locking slider 21 is also connected to the second elastic member. The other end of the rotating handle 31 is provided with a stop portion 312. The cover 33 is fitted onto the battery locking assembly 20 and is fixedly connected to the battery sealing plate 10. A slot 331 is provided on the cover 33. The rotating handle 31 rotates relative to the locking slider 21 to screw into or out of the slot 331. A stop groove 332 is provided in the slot 331. When the rotating handle 31 is screwed into the slot 331, the stop portion 312 engages with the stop groove 332 to prevent the locking slider 21, which protrudes from the battery sealing plate 10, from retracting.

[0064] Specifically, in this embodiment, the rotating handle 31 has a plate-like structure. The rotating handle 31 rotates relative to the locking slider 21. When the plane of the rotating handle 31 is perpendicular to the plane of the battery cover 10, the rotating handle 31 is located in the square slot 331 on the cover 33. At this time, the end of the locking slider 21 protrudes from the battery cover 10, so that the stop portion 312 at the end of the rotating handle 31 is engaged in the stop groove 332. At this time, the rotating handle 31 and the locking slider 21 are fixed relative to the cover 33, that is, the rotating handle 31 and the locking slider 21 are fixed relative to the battery cover 10. By providing a second elastic member, when the stop portion 312 is located in the stop groove 332, a pulling force is provided to the rotating handle 31, so that the stop portion 312 remains in contact with the stop groove 332, preventing the stop portion 312 from rotating out of the stop groove 332. In the event of violent movement or collision, the stop part 312 can be firmly locked into the stop groove 332 to prevent the locking slider 21 from retracting.

[0065] Specifically, in this embodiment, each of the two locking sliders 21 is hinged with a rotating handle 31. The second elastic element is a tension spring 32. Both ends of the tension spring 32 are connected to the hinged ends of the two rotating handles 31, respectively. In this embodiment, the two rotating handles 31 rotate in opposite directions; they rotate towards each other to lift and in opposite directions to lower. The two ends of the tension spring 32 are connected to the two rotating handles 31, providing a tendency for the two rotating handles 31 and the locking sliders 21 to move in opposite directions.

[0066] Furthermore, a limiting pin 311 is fixed to the end of the rotary handle 31 away from the stop part 312. The two ends of the tension spring 32 are respectively sleeved on the limiting pins 311 of the two rotary handles 31. By interfering with the limiting pins 311 at the ends of the tension spring 32, the tension spring 32 is sleeved on the limiting pins 311, so that the rotation of the rotary handle 31 does not affect the direction of the tension force of the tension spring 32.

[0067] Furthermore, when the rotating handle 31 is screwed into the slot 331, the rotating handle 31 is parallel to the plane of the battery cover plate 10, and the hinge axis between the rotating handle 31 and the locking slider 21 is higher than the connection position between the rotating handle 31 and the second elastic element. Specifically, the rotating handle 31 is hinged to the locking slider 21 by a screw 313. When the rotating handle 31 is lowered, the plane of the rotating handle 31 is parallel to the plane of the battery cover plate 10, and the mounting position of the screw 313 of the rotating handle 31 is higher than the mounting position of the limit pin 311. That is to say, there is a height difference between the position of the tension spring 32 and the rotation center of the rotating handle 31, so that while the tension spring 32 tightens the rotating handle 31, it generates a component force perpendicular to the battery cover plate 10 on the rotating handle 31, thereby effectively making the rotating handle 31 parallel to the plane of the upper substrate of the battery after folding, without protruding from the cover 33.

[0068] In this embodiment, the cover 33 has openings 333 at both ends. The locking slider 21 passes through the openings 333 to protrude or retract within the battery cover 10. It is understood that the cover 33 covers the battery locking assembly 20 to prevent the internal structure from being exposed.

[0069] Please refer to Figures 11-13 The working principle and process of the quick-release battery structure provided in this embodiment include:

[0070] Figure 11 This is a schematic diagram of the battery quick-release structure in the locked state. At this time, the locking slider 21 is subjected to the elastic force of the compression spring 22 and protrudes from both sides of the battery sealing plate 10. The two rotating handles 31 engage with the locking slider 21 respectively and are in the lowered state. At this time, the rotating handles 31 are located within the slot 331, and the stop part 312 is engaged within the stop groove 332, preventing the rotating handles 31 and the locking slider 21 from retracting inwards.

[0071] Figure 12 This is a schematic diagram of the quick-release battery mechanism when the rotating handle 31 is lifted. At this point, the operator pulls the rotating handle 31, raising it to a vertical position. The end of the rotating handle 31 then abuts against the locking slider 21, preventing further rotation. The tension spring 32 is in an extended state, providing an inward contraction force to the rotating handle 31 and the locking slider 21. The compression spring 22 provides an outward protrusion force to the locking slider 21. Since the tension force of the tension spring 32 is less than the thrust force of the compression spring 22, the compression spring 22 is not further compressed, and the locking slider 21 still protrudes beyond the battery cover 10.

[0072] Figure 13 This is a schematic diagram of the battery quick-release mechanism in its unlocked state. At this point, the operator further squeezes the two rotating handles 31, manually applying an inward retraction force. This causes the inward retraction force of the locking sliders 21 to exceed the thrust of the compression spring 22, causing the two locking sliders 21 to move inward until the guide post 11 abuts against the side wall of the guide groove 211. The locking sliders 21 then fully retract and cannot slide further. At this point, the battery pack 1000 can be removed from the robot's cavity, achieving quick disassembly of the battery pack 1000.

[0073] This quick-release battery structure also has a reset function. When the operator releases the rotating handle 31, the locking slider 21 protrudes from the battery cover plate 10 under the action of the compression spring 22. The rotating handle 31 rotates automatically under the action of the tension spring 32 and screws into the slot 331, so that the stop part 312 is engaged in the stop groove 332, re-fitting and preventing the locking slider 21 from moving inward.

[0074] Second Embodiment

[0075] Please refer to Figure 14 and Figure 15This embodiment provides a quick-release battery structure, the structure of which is roughly the same as the quick-release battery structure in the first embodiment, except that:

[0076] The locking stop assembly 30 in this embodiment includes a slide switch 34. The slide switch 34 is disposed between two locking sliders 21. A sliding limit block 341 is provided at one end of the slide switch 34. The slide switch 34 slides in a direction perpendicular to the sliding direction of the locking sliders 21, so that the sliding limit block 341 slides into the space between the two locking sliders 21 to prevent the locking sliders 21 protruding from the battery cover plate 10 from retracting, or slides out of the space between the two locking sliders 21 so that the locking sliders 21 can retract into the battery cover plate 10.

[0077] In this embodiment, a handle 213 protrudes from the top of the locking slider 21. Under the action of the compression spring 22, the locking slider 21 protrudes outward. By sliding the sliding switch 34, the sliding limit block 341 slides between the two locking sliders 21, and the locking slider 21 abuts against the sliding limit block 341 to prevent the locking slider 21 from retracting inward under external force. At this time, it can only be unlocked by sliding the switch 34. Sliding the switch 34 moves the sliding limit block 341 out from between the two locking sliders 21, so that the operator can move the locking slider 21 inward through the handle 213.

[0078] Furthermore, in this embodiment, an elastic buckle 342 is also provided at the end of the sliding switch 34 away from the sliding limit block 341. Elastic protrusions 343 are fixed on both sides of the elastic buckle 342. The sliding switch 34 slides to move the elastic buckle 342 from one end of the elastic protrusions 343 to the other end. The distance between the elastic protrusions 343 is less than the width of the elastic buckle 342. It is understood that when the operator slides the sliding switch 34, a certain force needs to be applied to deform the elastic protrusions 343 and the elastic buckle 342, so that the elastic buckle 342 can smoothly slide between the elastic protrusions 343, preventing accidental unlocking that would cause the locking slider 21 to retract.

[0079] Third Embodiment

[0080] This embodiment provides a robot that includes the quick-release battery structure of the battery pack 1000 provided in the first or second embodiment described above. The robot has a cavity for installing the battery pack 1000. A locking slot is provided on the cavity. When the battery pack 1000 is installed in the cavity, the locking slider 21 protrudes from the battery sealing plate 10 and enters the locking slot to fix the battery pack 1000 in the cavity.

[0081] In this embodiment, the locking stop assembly 30 prevents the locking slider 21 from retracting, thus avoiding the battery pack 1000 from falling out of the cavity in emergency situations such as violent robot movement or falls.

One end of the first elastic member abuts against the opposite side of the locking sliders 21. The sliding limiting mechanism limits the sliding direction and stroke of the locking sliders 21, so that the locking sliders 21 slide out of the battery sealing plate 10 in opposite directions, or slide back into the battery sealing plate 10 in opposite directions. The locking stop assembly 30 is disposed on the battery locking assembly 20. The locking stop assembly 30 has a locked state and an unlocked state. In the locked state, the locking stop assembly 30 prevents the locking sliders 21 protruding from the battery sealing plate 10 from retracting. In the unlocked state, the locking stop assembly 30 unlocks so that the locking sliders 21 can retract into the battery sealing plate 10. The battery pack 1000 includes a quick-release battery structure, a housing 200, and a battery module 300. The battery module 300 is disposed within the housing 200. A battery sealing plate 10 encloses the housing 200. The robot includes the battery pack 1000. The robot has a cavity for mounting the battery pack 1000. A locking slot is provided on the cavity. When the battery pack 1000 is installed in the cavity, the locking slider 21 protrudes from the battery sealing plate 10 and enters the locking slot. By setting the locking slider 21 to protrude from the battery sealing plate 10 and enter the locking slot, the battery pack 1000 can be locked in the cavity and fixed. By setting the locking stop assembly 30, the locking slider 21 is prevented from retracting, preventing the battery pack 1000 from detaching from the robot in special circumstances. This utility model can prevent the battery from detaching from the robot body in the event of violent movement or falls, improve the stability and reliability of battery installation, and realize quick battery installation and removal.
