[0045] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0046] The present application discloses a battery locking device 10 , which is applied to a vehicle.

[0047] Reference below Figure 1-Figure 8 A battery locking device 10 according to an embodiment of the present application is described.

[0048] In some embodiments, Figure 1 and Figure 3 As shown, the battery locking device 10 includes a lock housing 11 , a lock tongue 12 , a stopper 13 and a lock pin 14 .

[0049] The lock housing 11 has an opening 111 and a first connecting structure 1131 for connecting to one of a vehicle body and a battery; the lock tongue 12 is rotatably installed in the lock housing 11 between a first position and a second position, and the lock tongue 12 defines a locking groove with the opening 111 when in the first position; the stop member 13 is movably installed in the lock housing 11 between a third position and a fourth position, and the stop member 13 is used to lock the lock tongue 12 in the first position when in the third position; the lock pin 14 has a second connecting structure 1411 for connecting to the other of the vehicle body and the battery.

[0050] When the lock pin 14 is located in the locking groove, the lock tongue 12 is located in the first position, and the stopper 13 is located in the third position, the battery locking device 10 is locked; when the lock pin 14 is located in the locking groove, the lock tongue 12 is located in the first position, and the stopper 13 is located in the fourth position, the lock pin 14 can drive the lock tongue 12 to rotate to the second position to disengage the lock pin 14 from the opening 111 until the battery locking device 10 is unlocked.

[0051] The first connection structure 1131 may include but is not limited to a threaded hole, a buckle or a pin, etc. For example, in some embodiments, Figure 1-Figure 4 and Figure 7 As shown, the first connection structure 1131 is a threaded hole, that is, the locking pin 14 is threadedly connected to the other of the vehicle body and the battery.

[0052] The first connection structure 1131 may be provided in one or more forms, wherein the term "more" means two or more forms. For example, in some embodiments, Figure 1-Figure 4 and Figure 7 As shown, four first connection structures 1131 may be provided.

[0053] The displacement mode of the stopper 13 between the third position and the fourth position may include but is not limited to sliding, rotating or rolling, etc. For example, in some embodiments, Figure 1-Figure 2 As shown, the stopper 13 is displaced between the third position and the fourth position by sliding.

[0054] The second connection structure 1411 may include but is not limited to a threaded hole, a buckle or a pin, etc. For example, in some embodiments, Figure 4 and Figure 6 As shown, the second connection structure 1411 is a threaded hole, that is, the lock housing 11 is threadedly connected to one of the vehicle body and the battery.

[0055] The second connection structure 1411 may be provided in one or more forms, wherein the term "more" means two or more forms. For example, in some embodiments, Figure 4 and Figure 6 As shown, four second connection structures 1411 may be provided.

[0056] In actual implementation, Figure 1-Figure 2 As shown, the locking process can be achieved in the following manner: the lock pin 14 slides upward along the opening 111 to enter the lock shell 11. During the sliding process of the lock pin 14, the lock pin 14 can drive the lock tongue 12 to rotate from the second position to the first position. After the lock tongue 12 rotates to the first position, the stopper 13 moves from the fourth position to the third position. At this time, the stopper 13 blocks the opening 111, and the stopper 13 stops the lock tongue 12. The lock tongue 12 clamps the lock pin 14, and the lock pin 14 passes through the locking groove, thereby achieving locking between the battery and the vehicle body; the unlocking process can be achieved in the following manner: the stopper 13 moves from the third position to the fourth position, and the lock shaft 142 slides downward along the opening 111. During the sliding process of the lock pin 14, the lock pin 14 can drive the lock tongue 12 to rotate from the first position to the second position. Finally, the lock shaft 142 leaves the lock shell 11 through the opening 111, thereby achieving unlocking between the battery and the vehicle body.

[0057] It should be noted that the driving mode of the stopper 13 may include but is not limited to motor drive, cylinder drive or manual drive, etc., which is not limited here.

[0058] The battery locking device 10 provided in the embodiment of the present application, through the arrangement of the above-mentioned lock shell 11, lock tongue 12, stopper 13 and lock pin 14, cleverly utilizes the transmission relationship and position restriction between the various components to achieve locking and unlocking between the vehicle body and the battery, so as to realize convenient battery replacement of the vehicle, simplify the overall structure of the device, reduce the complexity of assembly and disassembly, and realize overall miniaturization and lightweight design; at the same time, effectively improve the structural strength of the entire battery locking device 10, thereby improving the reliability of the connection between the vehicle body and the battery, and thus extending the service life of the entire battery locking device 10; in addition, effectively reduce the probability of damage and the difficulty of repair, thereby reducing the maintenance cost of the entire battery locking device 10.

[0059] In some embodiments, Figure 1-Figure 2 and Figure 7 As shown, the lock housing 11 may be provided with a slide groove 112 , and the stopper 13 may be slidably installed in the slide groove 112 between a third position and a fourth position along a first direction.

[0060] like Figure 4 and Figure 7-Figure 8As shown, the lock housing 11 may include a lock base 113 and a lock cover 114, the lock base 113 and the lock cover 114 may jointly define an accommodating cavity, the lock tongue 12 and the stop member 13 may be installed in the accommodating cavity, and the slide groove 112 may be a part of the accommodating cavity, the stop member 13 may be slidably installed in the slide groove 112, wherein the lock base 113 may include a substrate 1133 and an enclosure structure 1134, the enclosure structure 1134 may protrude from the substrate 1133, the enclosure structure 1134 may be integrally formed with the substrate 1133, and the enclosure structure 1134 may be provided with a connecting hole, and the lock base 113 may be connected to the lock cover 114 by bolt connection or other connection methods through the connecting hole.

[0061] The stopper 13 can be slidably mounted on the slide groove 112 between the third position and the fourth position along the first direction, and the lock shaft 142 can be slidably matched with the opening 111 along the second direction. Figure 1-Figure 2 and Figure 7 As shown, the first direction is perpendicular to the second direction.

[0062] The battery locking device 10 provided in the embodiment of the present application has a structural design in which the stop member 13 is slidably installed in the slide groove 112. Compared with the rotating installation method or the rolling installation method, the space required by the stop member 13 is smaller, and there is no need to enlarge the size of the lock shell 11 for the arrangement of the stop member 13, thereby achieving an overall miniaturized and lightweight design. At the same time, the stroke of the stop member 13 is easier to control, reducing the stroke interference between the stop member 13, the lock shaft 142, and the lock tongue 12, thereby improving the efficiency of opening and closing the lock.

[0063] In some embodiments, Figure 1-Figure 2 and Figure 5 As shown, a guide structure 131 may be provided at one end of the stop member 13 , and the guide structure 131 may be used to cooperate with the lock tongue 12 and the lock housing 11 when the stop member 13 slides from the fourth position to the third position.

[0064] It is understandable that if the stop member is not provided with a guide structure, during the locking process of the battery locking device, the lock tongue rotates from the second position to the first position, and the stop member slides from the fourth position to the third position. During the sliding process of the stop member, the stop member is prone to interfere with the lock tongue or the lock shell, causing the lock tongue or the lock shell to be stuck to the stop member, so that the sliding stroke of the stop member is disturbed and cannot reach the target position, thereby causing the battery locking device to fail.

[0065] When a guide structure 131 is provided at one end of the stop member 13, the interference between the stop member 13 and the lock tongue 12 or the lock shell 11 is reduced, and the probability of the lock tongue 12 or the lock shell 11 hitting the stop member 13 is reduced, so that the stop member 13 can reach the target position more smoothly during the sliding stroke, thereby reducing the probability of failure of the battery locking device 10 and further reducing the maintenance cost of the entire battery locking device 10.

[0066] In some embodiments, Figure 1-Figure 2 and Figure 5 As shown, the guide structure 131 may include a first guide surface 1311 and a second guide surface 1312 on the stop member 13. The first guide surface 1311 and the second guide surface 1312 may be inclined with respect to the first direction. The first guide surface 1311 may be used to cooperate with the lock housing 11, and the second guide surface 1312 may be used to cooperate with the lock tongue 12.

[0067] In this embodiment, if Figure 1-Figure 2 and Figure 5 As shown, the first guide surface 1311 and the second guide surface 1312 can be arranged at the head of the stop member 13, the first guide surface 1311 and the second guide surface 1312 can be arranged opposite to each other, the distance between the first guide surface 1311 and the second guide surface 1312 can gradually decrease from the tail of the stop member 13 to the head of the stop member 13, and the length of the second guide surface 1312 can be greater than the length of the first guide surface 1311. Specifically, the length of the second guide surface 1312 can extend to the side wall of the stop member 13. During the sliding process of the stop member 13, the head of the stop member 13 can move from one side of the opening 111 to the other side of the opening 111. The first guide surface 1311 can guide the head of the stop member 13 to dock with the slide groove 112 on the other side of the opening 111, and the second guide surface 1312 can guide the head of the stop member 13 and part of the side wall to smoothly cooperate with the lock tongue 12.

[0068] The battery locking device 10 provided in the embodiment of the present application, through the setting of the above-mentioned first guide surface 1311 and the second guide surface 1312, makes the original sharp angle of the edge of the stop member 13 become gentle, removes the burrs on the stop member 13 caused by machining, and plays a positioning and guiding role when the stop member 13 cooperates with the lock shell 11 and the lock tongue 12, thereby reducing the probability of the lock tongue 12 or the lock shell 11 hitting the stop member 13.

[0069] In some embodiments, Figure 1-Figure 2 As shown, the rotation axis of the locking tongue 12 can be offset relative to the movement direction of the locking pin 14 .

[0070] It can be understood that if the rotation axis of the lock tongue is not offset with respect to the movement direction of the lock pin, in other words, if the rotation axis of the lock tongue is arranged directly opposite to the movement direction of the lock pin, when the lock pin slides upward along the opening and enters the lock shell, during the sliding process of the lock pin, the force of the lock pin on the lock tongue is just directed to the rotation axis of the lock pin, the force of the lock pin on the lock tongue cannot be converted into torque, resulting in the lock tongue being unable to rotate from the second position to the first position, and the battery locking device being unable to complete the locking action.

[0071] When the rotation axis of the lock tongue 12 is offset relative to the movement direction of the lock pin 14, since the lock pin 14 acts on the lock tongue 12 at a certain distance from the rotation axis, the force can be converted into torque, thereby driving the lock tongue 12 to rotate from the second position to the first position, thereby realizing the locking action of the battery locking device 10, thereby ensuring the feasibility and practicality of the battery locking device 10.

[0072] In some embodiments, Figure 1-Figure 2 As shown, when the locking tongue 12 is located at the second position, the center of gravity of the locking tongue 12 may be located directly below the rotation axis of the locking tongue 12 in the direction of gravity.

[0073] In actual implementation, Figure 2 As shown, when the battery locking device 10 is in the unlocked state, that is, the lock shaft 142 has left the lock housing 11 through the opening 111, the lock tongue 12 can be kept in the second position based on its own gravity. In this way, when the new battery needs to be installed on the vehicle body after the battery replacement is completed, there is no need to move the lock tongue 12 to the second position in advance, and the lock shaft 142 can be directly inserted into the lock housing 11 through the opening 111.

[0074] The battery locking device 10 provided in the embodiment of the present application, through the center of gravity design of the above-mentioned lock tongue 12, can keep the lock tongue 12 in the second position driven by its own gravity after the battery locking device 10 is unlocked, and there is no need to move the lock tongue 12 in advance before the next locking, which simplifies the steps of the locking action, reduces the difficulty and complexity of the operation, and thus improves the user's sense of use and experience.

[0075] In some embodiments, Figure 1-Figure 2 As shown, the battery locking device 10 may further include an elastic member 15 .

[0076] The elastic member 15 may be elastically connected between the lock tongue 12 and the lock housing 11 , and the elastic member 15 may be used to drive the lock tongue 12 to remain in the second position.

[0077] The elastic member 15 may include but is not limited to a spring, an elastic sleeve or a rubber ring, etc., which is not limited here.

[0078] like Figure 4 and Figure 7-Figure 8 As shown, the lock shell 11 may include a lock base 113 and a lock cover 114, and the lock base 113 and the lock cover 114 may jointly define a accommodating cavity, and the lock tongue 12, the stopper 13 and the elastic member 15 may be installed in the accommodating cavity, wherein the lock base 113 may include a substrate 1133 and a surrounding structure 1134, the surrounding structure 1134 may protrude from the substrate 1133, the surrounding structure 1134 may be integrally formed with the substrate 1133, the substrate 1133 may be provided with a connecting column, the connecting column may be located in the surrounding structure 1134, the first connecting structure 1131 may be located outside the surrounding structure 1134, the lock tongue 12 may be provided with a connecting hole, one end of the elastic member 15 may be hooked with the connecting column of the substrate 1133, and the other end of the elastic member 15 may be connected to the connecting hole of the lock tongue 12, and when the elastic member 15 is elastically connected between the lock tongue 12 and the lock shell 11, the elastic member 15 is in a stretched state.

[0079] In actual implementation, Figure 1-Figure 2 As shown, in the process of the lock shaft 142 driving the lock tongue 12 to rotate from the second position to the first position, the lock shaft 142 can overcome the elastic force of the elastic member 15 and move upward along the opening 111; in the process of the elastic force of the elastic member 15 driving the lock tongue 12 to rotate from the first position to the second position, the lock shaft 142 can move downward along the opening 111 to disengage from the lock housing 11.

[0080] The battery locking device 10 provided in the embodiment of the present application prevents the lock tongue 12 from being stuck in the first position with the rotation axis and the gravity of the lock tongue 12 is insufficient to drive the lock tongue 12 to fall back to the second position through the arrangement of the above-mentioned elastic member 15. After the battery locking device 10 is unlocked, the lock tongue 12 is moderately maintained in the second position with the assistance of the elastic member 15. At the same time, the elastic member 15 is not easy to fall off and is durable. It has a simple structure, a single assembly part, and a low requirement for processing accuracy, which is conducive to installation.

[0081] In some embodiments, Figure 1-Figure 2 As shown, the locking tongue 12 may include a first arm 121 and a second arm 122 connected to each other, the length of the first arm 121 may be greater than the length of the second arm 122, the elastic member 15 may be connected to the second arm 122, and the rotation axis of the elastic member 15 and the locking tongue 12 may be located on the same side of the opening 111.

[0082] In this embodiment, if Figure 1-Figure 2 As shown, in the process of the lock shaft 142 driving the lock tongue 12 to rotate from the second position to the first position, the lock shaft 142 can stop the first arm 121 of the lock tongue 12. When the lock tongue 12 is in the first position and the second position, the elastic member 15 can be in a stretched state, and the elastic member 15 and the rotating shaft can both be located on the side of the opening 111 away from the slide groove 112.

[0083] In other embodiments, the elastic member 15 may be connected to the first arm 121 , the elastic member 15 may be in a compressed state, and both the elastic member 15 and the rotating shaft may be located on a side of the opening 111 close to the slide groove 112 .

[0084] The battery locking device 10 provided in the embodiment of the present application is designed with a connection relationship between the first arm 121, the second arm 122 and the elastic member 15, so that the elastic member 15 is connected to the second arm 122 and the lock shaft 142 acts on the first arm 121, thereby increasing the force arm length of the lock shaft 142 on the lock tongue 12. During the locking process, the force required for the lock shaft 142 to move upward is smaller, which saves more effort during battery replacement installation.

[0085] In some embodiments, Figure 3 As shown, the outer wall of the lock housing 11 may be provided with a groove 1132 , and the groove 1132 may be communicated with the opening 111 . When the stopper 13 is in the first position, the lock pin 14 may be locked with the groove 1132 .

[0086] In this embodiment, if Figure 3 and Figure 7-Figure 8 As shown, the lock shell 11 is a hollow structure, and the opening 111 can pass through the entire lock shell 11 in the front-to-back direction, that is, the lock base 113 and the lock cover 114 both have the opening 111, and the opening 111 can include a first section and a second section, the second section can be open outward, the width of the second section along the first direction is not less than the width of the first section along the first direction, and the width of the second section gradually decreases from the direction away from the first section to the first section, the groove 1132 can be arranged on the periphery of the first section, and during the locking process of the battery locking device 10, the lock shaft 142 can slide from the second section to the first section until the lock pin 14 is locked with the groove 1132.

[0087] The battery locking device 10 provided in the embodiment of the present application realizes the limited locking between the lock pin 14 and the lock shell 11 in the front-to-back direction through the setting of the above-mentioned groove 1132, so that the lock pin 14 may not protrude from the outer wall of the lock shell 11, thereby improving the flatness of the outer surface of the lock shell 11 and facilitating the assembly of the lock shell 11. At the same time, in conjunction with the shape design of the opening 111, it plays a limiting and guiding role in the displacement of the lock shaft 142 during the unlocking and locking process, thereby improving the control accuracy of the stroke of the lock shaft 142.
