Description

Battery locking assembly, frame tube integrated battery, and frame tube mechanism Technical Field This application relates to the technical field of energy storage for bicycles and, in particular, to a battery locking assembly, a battery integrated into the frame tube, and a frame tube mechanism. Background of the Technique In electric bicycles, to prevent theft of the battery located in the frame tube, most manufacturers use integrated battery packs, such as the one disclosed in Chinese patent document CN106080922A. In this design, the battery is secured by a locking mechanism in a recessed section of the frame tube. However, due to the frame tube's structural design, when the bicycle is upright, the frame tube is often angled. In such cases, if the rider wants to remove the battery, they must use one hand to maintain the bicycle's balance and can only use the other hand to unlock the locking mechanism. Once unlocked, the battery can fall from the angled frame tube due to its own weight, making removal difficult for the rider. Contents of the Utility Model The purpose of this application is to overcome the deficiencies of the prior art and provide a battery locking assembly, a battery integrated into the frame tube, and a frame tube mechanism that are better suited to the actual usage habits of the cyclist and that facilitate the removal of the battery body.

The battery locking assembly also includes a retention and movement limitation element. The retaining and movement-limiting element is positioned on the coupling surface and connected to the battery seat. When the coupling surface is unlocked from the fixed locking seat, this element is designed to approach and engage with an interlocking structure of the fixed locking seat. The battery seat can also be displaced relative to the fixed locking seat, so that a thrust portion of the retaining and movement-limiting element is exposed outside the fixed locking seat. This thrust portion is designed to separate and release from the locking structure of the fixed locking seat upon a second unlocking. In some embodiments, the retaining and movement-limiting element has a locking protrusion formed on it, the locking protrusion partially protruding from the coupling surface; the retaining and movement-limiting element is locked, through the locking protrusion, into an engagement notch of the fixed locking seat. In some embodiments, the retaining and movement-limiting element comprises, successively connected, a flexible portion, said locking protrusion, and said thrust portion; the flexible portion is fixedly connected to the battery seat and is configured to deform elastically when said thrust portion is displaced. In some embodiments, the battery seat has a housing cavity formed in the coupling surface, with a portion of the retaining and movement-limiting element movably arranged inside said housing cavity, and the locking protrusion partially protruding outside of it. In some embodiments, the outer surface of the battery seat has a finger notch; this finger notch communicates with the housing cavity and is arranged in a position facing the thrust portion of the retaining and movement-limiting element; and / or The retaining and movement-limiting element is in sliding contact with the walls of the housing cavity. In some embodiments, the battery seat has a guidance structure formed on the coupling surface; this guidance structure is configured to engage, by means of a male-female coupling, with a guiding structure of the fixed locking seat, so that the battery seat moves relative to the fixed locking seat in the guiding direction of this guiding structure. In some embodiments, the orientation structure is a guide protrusion, one side of the guide protrusion opposite the guiding direction being configured to press against an elastic return element located inside a guide channel of the fixed locking seat, so that the guide protrusion moves along the guide channel under the pushing action of the elastic return element. In some embodiments, a battery is provided integrated into the frame tube, comprising a battery body and the battery locking assembly according to any of the above embodiments, with the battery seat installed on the outside of the battery body. In some embodiments, a frame tube mechanism is provided comprising a frame tube, a fixed locking seat, and the frame tube-integrated battery according to any of the above embodiments; the fixed locking seat is installed on the frame tube, the frame tube-integrated battery is detachably mounted on the angled frame tube, and the coupling surface is locked with the fixed locking seat; the retaining and movement-limiting element locks into the locking structure of the fixed locking seat when the coupling surface is unlocked from the fixed locking seat. In some embodiments, the frame tube mechanism further comprises a mounting base; said mounting base is installed on the frame tube; one end of the frame tube-integrated battery, away from the fixed locking seat, is detachably coupled to the mounting base; the mounting base has a rotating support portion that projects toward the frame tube-integrated battery; the rotating support portion rests against the frame tube-integrated battery and acts as a center of rotation when the frame tube-integrated battery is removed from the frame tube; and / or The fixed lock seat comprises a lock body and a fixed base body, the interlocking structure being connected to the fixed base body; the battery seat has a lock groove formed in the mating surface, and the lock body is installed in the fixed base body; a locking tongue of the lock body is configured to be inserted into the lock groove, so that the mating surface is locked to the fixed lock seat, or the locking tongue of the lock body is configured to be pulled away from the lock groove, so that the mating surface is unlocked from the fixed lock seat. Advantageous effects Compared to the prior art, the present application offers at least the following advantages: 1) Since the mounting surface detachably mounts the battery pack to the angled frame tube by means of its locking engagement with the fixed locking seat, and since the retaining and movement-limiting element is installed on said mounting surface, before the first unlocking, the retaining and movement-limiting element is not in contact with the fixed locking seat. After this first unlocking, the retaining and movement-limiting element can approach and engage with the locking structure of the fixed locking seat, creating an interference action that overcomes the weight of the battery pack. In this way, the battery pack can remain in the frame tube, reducing its descent during the first unlocking. 2) After unlocking between the coupling surface and the fixed locking seat, the battery seat can be moved relative to the fixed locking seat, so that the thrust portion of the retaining and movement-limiting element is exposed outside the fixed locking seat. When the bicycle is upright, the rider can reach and operate the push-in portion with one hand to perform a second unlocking, causing the retaining and movement-limiting element to move away from and detach from the fixed locking seat's interlocking structure. The battery unit can then be safely removed from the frame tube with the rider's assistance. The described battery locking assembly is better suited to the rider's actual usage habits, effectively improving the convenience of battery unit removal.

The terms "vertical," "horizontal," "left," and "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiment. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by a person skilled in the technical field to which this application pertains. The terms used herein are for the sole purpose of describing specific embodiments and are not intended to limit the scope of this application. The term "and / or" as used herein includes any and all combinations of one or more of the related listed elements. For a better understanding of the technical solution and the advantageous effects of this application, it is described in more detail below with reference to specific implementations: With reference to Figure 1, a battery locking assembly (110) according to one embodiment comprises a battery seat (1110) and a retaining and movement-limiting element (1120). The battery seat (1110) is configured to be installed on the outside of a battery body (120). The battery seat (1110) has a mating surface (1101), said mating surface (1101) being configured to lock into place with a fixed locking seat (300) located on a frame tube (200), such that the battery body (120) is detachably mounted on the inclined frame tube (200). The retaining and motion-limiting element (1120) is installed on the coupling surface (1101) and connected to the battery seat (1110). When the coupling surface (1101) is unlocked from the fixed locking seat (300), the retaining and motion-limiting element (1120) is configured to approach and lock into the locking structure of the fixed locking seat (300), and the battery seat (1110) moves relative to the fixed locking seat (300), so that the thrust portion (1123) of the retaining and motion-limiting element (1120) is exposed outside the fixed locking seat (300). The thrust portion (1123) of the retaining and movement-limiting element (1120) is configured to, during a second unlocking, move away from and detach from the locking structure of the fixed locking seat (300). It can be understood that, since the coupling surface (1101) detachably mounts the battery body (120) on the frame tube (200) arranged at an angle by means of locking it with the fixed locking seat (300) of the frame tube (200), and since the retaining and movement-limiting element (1120) is further installed on the coupling surface (1101), before performing a first unlocking between the battery seat (1110) and the fixed locking seat (300), the retaining and movement-limiting element (1120) is not in contact with the fixed locking seat (300).Thus, after the unlocking between the mating surface (1101) and the fixed locking seat (300), the retaining and movement-limiting element (1120) can approach and engage with the locking structure of the fixed locking seat (300), thereby creating an interference action between the retaining and movement-limiting element (1120) and the locking structure. This interference action can overcome the weight of the battery body (120), allowing the battery body (120) to remain in the frame tube (200), ultimately reducing the likelihood of the battery body (120) falling out of the frame tube (200) during the first unlocking. It can be understood that, after the unlocking between the coupling surface (1101) and the fixed locking seat (300), the battery seat (1110) can be moved in relation to the fixed locking seat (300), so that the thrust portion (1123) of the retaining and movement-limiting element (1120) is exposed outside the fixed locking seat (300).When the bicycle is in an upright position, the cyclist can more easily reach and operate the push portion (1123) with one hand to perform a second unlocking between the battery seat (1110) and the fixed lock seat (300). This is achieved, for example, by pushing the push portion (1123) of the retaining and movement-limiting element (1120) with a finger, causing the retaining and movement-limiting element (1120) to move away from and detach from the locking structure of the fixed lock seat (300). The battery body (120) can then be safely removed from the frame tube (200) with the support of the human hand (10). The described battery locking assembly (110) is better suited to the cyclist's actual usage habits, effectively improving the convenience of removing the battery body (120). In one embodiment, the locking structure of the fixed locking seat (300) may be, among other structures, an engagement groove, an engagement notch (3210) or an interlocking block; the above is indicated only as an example, and a person skilled in the art may make other selections according to requirements. In some embodiments, a portion of the restraining and motion-limiting element (1120) separate from the thrust portion (1123) is rotatably connected to the battery seat (1110) via a pivot axis. It can be understood that, since the battery seat (1110) and the portion of the restraining and motion-limiting element (1120) separate from the thrust portion (1123) are connected to each other via the pivot axis, when a finger pushes the thrust portion (1123) of the restraining and motion-limiting element (1120), the restraining and motion-limiting element (1120) can oscillate about the pivot axis under the action of the thrust force, so that the restraining and motion-limiting element (1120) moves stably and is released from the locking structure of the fixed locking seat (300). With reference to Figure 1, in some embodiments, the retaining and motion-limiting element (1120) has a locking protrusion (1122) formed on it, this locking protrusion (1122) partially projecting from the mating surface (1101). The retaining and motion-limiting element (1120) is locked, via the locking protrusion (1122), into the engagement notch (3210) of the fixed locking seat (300). It can be understood that, since the locking protrusion (1122) protrudes partially from the coupling surface (1101), when the coupling surface (1101) is unlocked from the fixed locking seat (300), the locking protrusion (1122) can lock into the engagement notch (3210) of the fixed locking seat (300), so that an interference action is formed between the retaining and movement-limiting element (1120) and the engagement notch (3210), thus being able to more effectively overcome the self-weight of the battery body (120), reducing the incidence of the battery body (120) falling during its removal. In the present embodiment, when the locking protrusion (1122) is locked into the engagement notch (3210) of the fixed locking seat (300), the locking protrusion (1122) and the engagement notch (3210) of the fixed locking seat (300) are arranged in mutually facing positions; when the locking protrusion (1122) is disengaged from the engagement notch (3210) of the fixed locking seat (300), the locking protrusion (1122) and the engagement notch (3210) of the fixed locking seat (300) are arranged in mutually offset positions. With reference to Figure 1, in some embodiments, the retaining and movement-limiting element (1120) comprises, successively connected, a flexible portion (1121), the locking protrusion (1122), and the thrust portion (1123). The flexible portion (1121) is fixedly connected to the battery seat (1110) and is configured to deform elastically when the thrust portion (1123) is displaced. It can be understood that, since the flexible portion (1121) of the retaining and movement-limiting element (1120) is fixedly connected to the battery seat (1110), when a finger actuates the push portion (1123) by displacing it, the push portion (1123) can transmit the push force to the flexible portion (1121), causing the flexible portion (1121) to deform elastically and displace relative to the battery seat (1110).Furthermore, since the locking protrusion (1122) is located between the flexible portion (1121) and the thrust portion (1123), when the flexible portion (1121) and the thrust portion (1123) are displaced, the retaining and movement-limiting element (1120) can be displaced as a whole, so that the locking protrusion (1122) alternates between a position facing the engagement notch (3210) of the fixed locking seat (300) and a position displaced from the engagement notch (3210) of the fixed locking seat (300). Likewise, once the finger is removed from the thrust portion (1123), the flexible portion (1121) can recover its original shape under the action of the elastic deformation force, so that the retaining and movement-limiting element (1120) automatically returns to its initial position as a whole. With reference to Figure 1, in some embodiments, the battery seat (1110) has a housing cavity (1104) formed in the coupling surface (1101), with a part of the retaining and movement-limiting element (1120) movably arranged inside the housing cavity (1104), and the locking protrusion (1122) partially protruding outside the housing cavity (1104). It can be understood that, since a part of the restraint and movement limiting element (1120) is movably arranged inside the housing cavity (1104), said housing cavity (1104) allows the restraint and movement limiting element (1120) to be partially housed, thus reducing its space occupation and improving the structural compactness of the battery seat (1110). At the same time, since the locking protrusion (1122) protrudes partially from the housing cavity (1104), the locking protrusion (1122) can lock into the engagement notch (3210) of the fixed locking seat (300); in this state, the housing cavity (1104) limits the range of motion of the retaining and motion-limiting element (1120), reducing the risk of the retaining and motion-limiting element (1120) being displaced with an excessive amplitude and fracturing during the process of disengaging the locking protrusion (1122) from the engagement notch (3210) of the fixed locking seat (300) when excessive finger force is applied. With reference to Figure 1, in some embodiments, the outer surface of the battery seat (1110) has a finger notch (1105); this finger notch (1105) communicates with the housing cavity (1104) and is positioned opposite the thrust portion (1123) of the retaining and movement-limiting element (1120). It can be understood that, since the finger notch (1105) formed on the outer surface of the battery seat (1110) faces the thrust portion (1123) of the retaining and movement-limiting element (1120) and communicates with the housing cavity (1104), the rider's finger can conveniently pass through the finger notch (1105) to actuate the thrust portion (1123), further improving the convenience of one-handed operation. With reference to Figure 1, in some embodiments, the pushing portion (1123) has an anti-slip structure formed thereon, this structure being oriented towards the finger groove (1105) and configured to make contact with the finger's skin surface. It can be understood that when the finger pushes the pushing portion (1123), the contact between the finger's skin surface and the anti-slip structure can increase contact friction during gripping and releasing, facilitating the application of force by the finger and further improving the stability of one-handed removal and insertion of the battery body (120). Specifically, the anti-slip structure may have a serrated, wavy, or other concave-convex shape; the foregoing is indicated only as an example, and a person skilled in the art may make other selections as required. With reference to Figure 1, in some embodiments, the retaining and motion-limiting element (1120) is in sliding contact with the walls of the housing cavity (1104). It can be understood that, since the retaining and motion-limiting element (1120) is in sliding contact with the walls of the housing cavity (1104), the walls of the housing cavity (1104) contact the retaining and motion-limiting element (1120), so that when the human hand (10) actuates the pushing portion (1123), the retaining and motion-limiting element (1120) can slide as a whole, remaining close to the walls of the housing cavity (1104), thus ensuring a uniform and stable displacement of the retaining and motion-limiting element (1120) as a whole. With reference to Figure 1, in some embodiments, the battery seat (1110) has an orientation structure formed on the coupling surface (1101); this orientation structure is configured to be coupled, by means of a male-female coupling, with a guiding structure of the fixed locking seat (300), so that the battery seat (1110) is displaced relative to the fixed locking seat (300) in the guiding direction of this guiding structure.It can be understood that, when the orientation structure of the coupling surface (1101) is coupled by a male-female type coupling with the guiding structure of the fixed locking seat (300), the displacement path of the orientation structure is limited by the interference action formed between the orientation structure and the guiding structure, thus reducing the deviation in the displacement direction of the battery seat (1110) when separating from the fixed locking seat (300), and ultimately enabling the battery seat (1110) to be stably separated from the fixed locking seat (300) in the guiding direction of the guiding structure. With reference to Figure 1, in some embodiments, the orientation structure is a guide protrusion (1111), one side of the guide protrusion (1111) opposite the guiding direction being configured to press against an elastic return element (3211) located inside a guide channel (3201) of the fixed locking seat (300), so that the guide protrusion (1111) moves along the guide channel (3201) under the pushing action of the elastic return element (3211).It can be understood that, by pressing the side of the guide protrusion (1111) away from the gripping area against the elastic return element (3211) located inside the guide channel (3201) of the fixed locking seat (300), when the coupling surface (1101) is unlocked from the fixed locking seat (300), the guide protrusion (1111) can be moved along the guide channel (3201) towards the human hand (10) under the action of the elastic force of the elastic return element (3211), further improving the convenience of removing the battery body (120) with one hand.In the present embodiment, the guiding protrusion (1111) and the thrust portion (1123) are arranged in mutually facing positions; when the human hand (10) actuates the thrust portion (1123) to perform the second unlocking, the force exerted by the elastic return element (3211) on the guiding protrusion (1111) is oriented towards the human hand (10), allowing the battery seat (1110), under the action of the elastic return element (3211), to move into the human hand (10). With reference to Figures 1 to 3, the present application also provides a battery integrated into the frame tube (100) comprising a battery body (120) and the battery locking assembly (110) according to any of the above embodiments; the battery seat (1110) is installed on the outside of the battery body (120). It can be understood that, when applying the battery locking assembly (110) of the present application to the battery integrated into the frame tube (100), since the coupling surface (1101) detachably mounts the battery body (120) to the frame tube (200) by locking it with the fixed locking seat (300) of the frame tube (200), and since the retaining and movement-limiting element (1120) is further installed on the coupling surface (1101), after unlocking between the coupling surface (1101) and the fixed locking seat (300), the retaining and movement-limiting element (1120) can lock into the locking structure of the fixed locking seat (300), thus forming an interference action between the retaining and movement-limiting element (1120) and the locking structure.This interference action can overcome the self-weight of the battery body (120), so that the battery body (120) can remain in the frame tube (200), ultimately reducing the incidence of the battery body (120) falling out during its removal. Furthermore, since, after the unlocking between the mating surface (1101) and the fixed locking seat (300), the battery seat (1110) can move relative to the fixed locking seat (300), so that the push portion (1123) of the retaining and movement-limiting element (1120) is exposed outside the fixed locking seat (300), when the bicycle is in an upright position, the cyclist can more easily and with one hand reach and actuate the push portion (1123) to perform a second unlocking between the battery seat (1110) and the fixed locking seat (300), for example, by pushing with a finger the push portion (1123) of the retaining and movement-limiting element (1120), causing the retaining and movement-limiting element (1120) to move away from and detach from the locking structure of the fixed locking seat. (300) ;The battery body (120) can then be safely removed from the frame tube (200) with the support of the human hand (10). With reference to Figures 1 to 3, the present application further provides a frame tube mechanism comprising a frame tube (200), a fixed locking seat (300), and a frame tube-integrated battery (100) according to any of the preceding embodiments. The fixed locking seat (300) is installed on the frame tube (200), the frame tube-integrated battery (100) is detachably mounted on the inclined frame tube (200), and the coupling surface (1101) is locked to the fixed locking seat (300). The retaining and movement-limiting element (1120) engages with the locking structure of the fixed locking seat (300) when the coupling surface (1101) is unlocked from the fixed locking seat (300).It can be understood that, with reference to Figure 4, since the retaining and movement-limiting element (1120) locks into the locking structure of the fixed locking seat (300) when the coupling surface (1101) is unlocked from the fixed locking seat (300), an interference action is formed between the retaining and movement-limiting element (1120) and the locking structure, this interference action being able to overcome the self-weight of the battery body (120), so that the battery integrated into the frame tube (100) can remain in the frame tube (200), ultimately reducing the incidence of the battery body (120) falling out of the frame tube (200) during the first unlocking. With reference to Figures 3 and 4, in some embodiments, the frame tube mechanism further comprises a mounting base (400). The mounting base (400) is installed on the frame tube (200). One end of the frame tube-integrated battery (100), located away from the fixed locking seat (300), is detachably coupled to the mounting base (400). The mounting base (400) has a rotating support portion (410) that protrudes toward the frame tube-integrated battery (100). The rotating support portion (410) rests against the frame tube-integrated battery (100) and acts as a center of rotation when the frame tube-integrated battery (100) is removed from the frame tube (200). It can be understood that, by detachably attaching the mounting base (400) to the end of the battery integrated into the frame tube (100) away from the fixed locking seat (300), with the coupling surface (1101) of the battery seat (1110) locked with the fixed locking seat (300), the battery integrated into the frame tube (100) can be detachably mounted on the frame tube (200). Furthermore, when the rotation support portion (410) of the mounting base (400) rests against the frame tube integrated battery (100), when the coupling surface (1101) is unlocked from the fixed locking seat (300), the frame tube integrated battery (100) can pivot around the rotation support portion (410) as a center of rotation for removal from the frame tube (200), making it easier to remove the frame tube integrated battery (100) with one hand. In the present embodiment, the rotating support portion (410) is located on the edge of the mounting base (400) side away from the frame tube (200) and is inclined in a direction away from the frame tube (200), forming an arched base configured to slide against the battery integrated into the frame tube (100). It can be understood that, when the arched base rests against the battery integrated into the frame tube (100), a smooth contact surface is formed, allowing the battery integrated into the frame tube (100) to slide relative to the arched base and be smoothly removed from the frame tube (200). With reference to Figures 1 and 4, in some embodiments, the fixed lock seat (300) comprises a lock body (310) and a fixed base body (320), the lock body (310) being installed in the fixed base body (320), and the battery seat (1110) having a lock groove (1103) formed in the coupling surface (1101). The locking tab (3110) of the lock body (310) is configured to be inserted into the lock slot (1103), so that the mating surface (1101) is locked to the fixed base body (320), or the locking tab (3110) of the lock body (310) is configured to be released from the lock slot (1103), so that the mating surface (1101) is unlocked from the fixed base body (320). It can be understood that, with the lock body (310) installed in the fixed base body (320) and the battery seat (1110) having the lock slot (1103) formed in the mating surface (1101), the locking tongue (3110) of the lock body (310) can be inserted into the lock slot (1103), so that the fixed locking seat (300) is locked to the mating surface (1101). Likewise, when the locking tongue (3110) of the lock body (310) is released from the lock slot (1103), the fixed locking seat (300) is unlocked from the mating surface (1101). The lock body (310) can be a conventional locking device, and therefore will not be described in further detail here. During opening, a key is inserted into the keyhole of the lock body (310) to, by means of the key, actuate the locking tongue (3110) so that it disengages from the locking groove (1103), separating the locking tongue (3110) from the battery seat (1110) and thus achieving unlocking between the fixed locking seat (300) and the mating surface (1101). Compared to the prior art, the present application offers at least the following advantages: 1) Since the coupling surface (1101) detachably mounts the battery body (120) on the frame tube (200) arranged at an angle by locking it with the fixed locking seat (300) of the frame tube (200), and since the retaining and movement-limiting element (1120) is further installed on the coupling surface (1101), before performing a first unlocking between the battery seat (1110) and the fixed locking seat (300), the retaining and movement-limiting element (1120) is not in contact with the fixed locking seat (300).Thus, after the unlocking between the mating surface (1101) and the fixed locking seat (300), the retaining and movement-limiting element (1120) can approach and engage with the locking structure of the fixed locking seat (300), thereby creating an interference action between the retaining and movement-limiting element (1120) and the locking structure. This interference action can overcome the weight of the battery body (120), allowing the battery body (120) to remain in the frame tube (200), ultimately reducing the likelihood of the battery body (120) falling out of the frame tube (200) during the first unlocking. 2) After unlocking between the coupling surface (1101) and the fixed locking seat (300), the battery seat (1110) can be moved relative to the fixed locking seat (300), so that the thrust portion (1123) of the retaining and movement-limiting element (1120) is exposed outside the fixed locking seat (300).When the bicycle is in an upright position, the cyclist can more easily reach and operate the push portion (1123) with one hand to perform a second unlocking between the battery seat (1110) and the fixed lock seat (300). This is achieved, for example, by pushing the push portion (1123) of the retaining and movement-limiting element (1120) with a finger, causing the retaining and movement-limiting element (1120) to move away from and detach from the locking structure of the fixed lock seat (300). The battery body (120) can then be safely removed from the frame tube (200) with the support of the human hand (10). The described battery locking assembly (110) is better suited to the cyclist's actual usage habits, effectively improving the convenience of removing the battery body (120). The embodiments described above represent only some embodiments of this application, the description of which is relatively specific and detailed, but should not be interpreted as limiting the scope of protection of this utility model. It should be noted that, for a person skilled in the art, without departing from the technical concept of this application, various modifications and improvements can be made, which are included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model will be determined in accordance with the appended claims.
