In addition, during the unlocking action, it is easy for one side to be unlocked and the other side to be stuck, which brings inconvenience to the user. Utility Model Content

[0004] In view of this, the utility model provides a battery locking device and an ultrasonic device to solve the problem of complex battery unlocking of existing ultrasonic devices.

[0005] In a first aspect, the utility model provides a battery locking device, comprising:

[0006] A cover body, on which a first card slot is formed;

[0007] A fixing seat, on which a mounting groove suitable for installing a battery is provided, the top of the mounting groove is provided with the cover body in an openable and closable manner, and the mounting groove is provided with a mounting hole corresponding to the first card slot;

[0008] The locking mechanism comprises a pressing assembly, a locking member and an elastic member abutting against the pressing assembly, wherein the pressing assembly is movably arranged on the fixing seat, one end of the elastic member abuts against the locking member, and the other end abuts against the fixing seat, the locking member is movably arranged in the fixing seat, and a limiting end is provided on the locking member corresponding to the first card slot;

[0009] The battery locking device has a locked state and an unlocked state. In the locked state, the elastic member enables the limit end to pass through the assembly hole and be clamped in the first slot, and the cover body is locked in the assembly slot. From the locked state to the unlocked state, the pressing assembly is pressed to overcome the elastic force of the elastic member so that the limit end is disengaged from the first slot, and the cover body is unlocked.

[0010] Beneficial effects: When installing the battery in the assembly groove of this battery locking device, it is necessary to cover the cover on the assembly groove. The limiting end of the locking member passes through the assembly hole and is clamped in the first card slot of the cover, so that the cover is locked on the assembly groove. If the user needs to remove or replace the battery, only need to press the pressing component. The pressing component overcomes the elastic force of the elastic component, causing the limiting end of the locking member to fall off the first card slot. At this time, the cover is unlocked, and the user can then remove the cover and then remove or replace the battery.

[0011] If the user needs to install the cover on the assembly groove and lock the cover on the assembly groove, the user only needs to cover the cover on the assembly groove and press the cover. When the first card slot of the cover is aligned with the assembly hole, the elastic component applies an elastic force to the locking member, pushing the locking member to move, so that the limiting end of the locking member passes through the assembly hole and is clamped into the first card slot. At this time, the cover is locked on the assembly groove, and the battery is locked tightly in the assembly groove.

[0012] Compared with the existing battery locking devices, the battery locking device of the present application has a simple structure and is easy to operate. The user can switch the cover of the battery between the locked state and the unlocked state with one hand, and at the same time avoid the phenomenon of jamming of the cover during the unlocking process.

[0013] In an optional embodiment, a plurality of the limiting ends are provided on the locking member, and the plurality of limiting ends are arranged at intervals.

[0014] Beneficial effects: By providing a plurality of limiting ends on the locking member, when in the locked state, the plurality of limiting ends on the locking member are respectively clamped in the corresponding first card slots, so that the cover is clamped by the plurality of limiting ends, ensuring that the cover is firmly and reliably locked in the locked state.

[0015] In an optional embodiment, an inclined surface is provided at the top of the limiting end. The inclined surface is inclined from the top surface of the limiting end to the bottom surface of the limiting end, and is inclined from the end close to the elastic component to the end far from the elastic component, and the inclined surface is adapted to cooperate with the cover.

[0016] Beneficial effects: By pressing the cover, the force received by the cover is transmitted to the inclined surface of the limiting end. The inclined surface of the limiting end is under pressure, causing the locking member to move, and the limiting end enters the assembly hole, so as to facilitate the cover to be covered on the assembly groove.

[0017] In an optional embodiment, the pressing component includes a pressing member and a pushing member fixedly connected to the pressing member. The pushing member is in contact with the locking member, and the contact surface between the pushing member and the locking member is inclined.

[0018] Beneficial effects: The pressing member and the pushing member are fixedly connected. By applying pressure to the pressing member, the pressing member moves under the force, and then drives the pushing member to move. Since the pushing member is abutted against the locking member, and the abutting surface between the pushing member and the locking member is inclined, during the movement of the pushing member, the inclined abutting surface is used to push the locking member to move, and the locking member realizes the switching between the locked state and the unlocked state during the movement, so as to facilitate the locking and unlocking of the cover body.

[0019] In an optional implementation manner, a second clamping groove is provided on the assembly groove, the second clamping groove is disposed opposite to the assembly hole, and a clamping buckle is provided on the cover body corresponding to the second clamping groove.

[0020] Beneficial effects: By providing a second clamping groove in the assembly groove and disposing the position of the second clamping groove opposite to the assembly hole, when locking the cover body, it is necessary to first snap the clamping buckle on the cover body into the second clamping groove, and then press the cover body so that the limiting end snaps into the first clamping groove, thereby locking the cover body. By the limiting end snapping into the first clamping groove and the clamping buckle snapping into the second clamping groove, the two ends of the cover body are limited and fixed, ensuring that the cover body is firmly locked on the assembly groove.

[0021] In an optional implementation manner, a spring piece is further included. One end of the spring piece is fixedly provided on the cover body. In the locked state, the spring piece is in a compressed state and the other end of the spring piece abuts against the fixed seat; in the unlocked state, the spring piece returns from the compressed state to the initial state and applies an elastic force to the cover body to make the cover body pop out of the assembly groove.

[0022] Beneficial effects: By providing a spring piece on the cover body and abutting the other end of the spring piece against the fixed seat, during the process of the cover body switching from the locked state to the unlocked state, the limiting end of the locking member disengages from the first clamping groove of the cover body. At this time, the cover body is unlocked, and the spring piece returns from the compressed state to the initial state, applying an elastic force to the cover body in the direction away from the assembly groove, so that the cover body pops out of the assembly groove, facilitating the user to take out the cover body.

[0023] In an optional implementation manner, limiting pins are respectively provided at both ends of the locking member, and one end of the elastic member is sleeved on the limiting pin.

[0024] Beneficial effects: By providing limiting pins on the locking member and sleeving one end of the elastic member on the limiting pin, it is ensured that the elastic member is stably matched with the locking member, so that the elastic member can provide a stable elastic force to the locking member, avoiding the elastic member disengaging from the locking member. At the same time, limiting pins are respectively provided at both ends of the locking member, and an elastic member is respectively provided on each limiting pin, so that the elastic member uniformly applies an elastic force to both ends of the locking member, ensuring that the elastic force applied by the elastic member to the locking member can stably push the locking member to move.

[0025] In an alternative embodiment, a guiding groove is formed in the locking member, a guiding member passing through the guiding groove is provided on the fixing base, a limiting block is fixedly provided at the end of the guiding member, and the locking member is disposed between the limiting block and the fixing base.

[0026] Advantageous effects: By providing a guiding groove on the locking member and a corresponding guiding member on the fixing base, and fixing the locking member on the guiding member with the limiting block, the locking member is disposed between the limiting block and the fixing base, ensuring that the locking member moves along the path of the guiding groove and avoiding phenomena such as deviation of the locking member during movement.

[0027] In an alternative embodiment, a buffer member is provided on the cover body, and the buffer member is disposed between the cover body and the battery.

[0028] Advantageous effects: By providing a buffer member between the cover body and the battery, the energy from external impacts or vibrations is absorbed and dispersed by the buffer member, reducing the impact force on the battery, protecting the battery from damage and extending the service life of the battery.

[0029] In a second aspect, the present utility model further provides an ultrasonic device including a battery locking device.

[0030] Advantageous effects: For this ultrasonic device, the user can switch the cover body of the battery between the locked state and the unlocked state with one hand, and at the same time avoid the phenomenon of jamming of the cover body during the unlocking process.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0042] In the related art, the unlocking key of the battery cover is designed at the top of the battery pack assembly. Some use a linear sliding unlocking method, which is relatively troublesome and laborious to operate and not user-friendly. Especially when two batteries share one battery cover, it requires two-handed operation and cannot meet the requirement of one-handed operation. In addition, during the unlocking process, the phenomenon of one side being unlocked while the other side is jammed easily occurs, bringing inconvenience to the user

[0043] To solve the above technical problems, the embodiments of the present utility model will be described below in conjunction with Figures 1 to 7 , to describe the embodiments of the present utility model

[0044] According to the embodiments of the present utility model, on the one hand, as shown in conjunction with Figures 1 to 3 , a battery locking device is provided, including a cover 1, a fixing seat 2, and a locking mechanism 11

[0045] As shown in conjunction with Figures 1 to 3 , a first card slot 101 is formed on the cover 1

[0046] The fixing base 2 is provided with an assembly groove 201, and the battery 3 is installed in the assembly groove 201. A cover body 1 is provided at the top of the assembly groove 201 in a manner that can be opened and closed, and an assembly hole 203 is provided on the assembly groove 201 corresponding to the first card slot 101 (as Figure 7 shown).

[0047] The locking mechanism 11 includes a pressing component 4, a locking member 5, and an elastic member 6. The pressing component 4 is in contact with the locking member 5. The pressing component 4 is movably arranged on the fixing base 2. One end of the elastic member 6 is in contact with the locking member 5, and the other end of the elastic member 6 is in contact with the fixing base 2. The locking member 5 is movably arranged in the fixing base 2. A limiting end 501 corresponding to the first card slot 101 is provided on the locking member 5, and it has a locking state and an unlocking state.

[0048] In the locking state, the elastic member 6 applies an elastic force to the locking member 5 so that the limiting end 501 passes through the assembly hole 203 and is clamped in the first card slot 101, locking the cover body 1 on the assembly groove 201. From the locking state to the unlocking state, pressing the pressing component 4 overcomes the elastic force of the elastic member 6 so that the limiting end 501 disengages from the first card slot 101, unlocking the cover body 1, that is, the battery locking device is in the unlocking state.

[0049] When the battery 3 is installed in the assembly groove 201, the cover body 1 needs to be covered on the assembly groove 201. The limiting end 501 of the locking member 5 passes through the assembly hole 203 and is clamped in the first card slot 101 of the cover body 1, locking the cover body 1 on the assembly groove 201. If the user needs to take out or replace the battery 3, only need to press the pressing component 4. The pressing component 4 overcomes the elastic force of the elastic member 6 so that the limiting end 501 of the locking member 5 falls off the first card slot 101. At this time, the cover body 1 is unlocked, and the user can remove the cover body 1 and then take out or replace the battery 3.

[0050] If the user needs to install the cover body 1 on the assembly groove 201 and lock the cover body 1 on the assembly groove 201, the user only needs to cover the cover body 1 on the assembly groove 201 and press the cover body 1. When the first card slot 101 of the cover body 1 is aligned with the assembly hole 203, the elastic member 6 applies an elastic force to the locking member 5, pushing the locking member 5 to move, so that the limiting end 501 of the locking member 5 passes through the assembly hole 203 and is clamped into the first card slot 101. At this time, the cover body 1 is locked on the assembly groove 201, locking the battery 3 in the assembly groove 201.

[0051] Compared with the existing battery locking device, the battery locking device of the present application has a simple structure and is easy to operate. The user can switch the cover body 1 of the battery 3 between the locking state and the unlocking state with one hand, and at the same time avoid the phenomenon of jamming of the cover body 1 during the unlocking process.

[0052] Specifically, the cover 1 can be set in regular shapes such as rectangles and squares, or can be set in other irregular shapes. In the embodiments of the present application, the specific shape of the cover 1 is not limited.

[0053] Specifically, the first card slot 101 matches the corresponding limiting end 501, ensuring that when the limiting end 501 is inserted into the first card slot 101, the cover 1 is firmly locked on the assembly slot 201. In the embodiments of the present application, the shapes of the first card slot 101 and the limiting end 501 are not specifically limited.

[0054] It should be noted that the pressing component 4 contacts the locking member 5, and by applying an external force to the pressing component 4, the locking member 5 can be moved in the direction towards or away from the assembly slot 201.

[0055] Specifically, the elastic member 6 can be a spring, a torsion spring, a tension spring, etc. In the embodiments of the present application, the type of the elastic member 6 is not specifically limited.

[0056] In the embodiments of the present application, the specific shapes of the pressing component 4 and the locking member 5 are not limited.

[0057] Specifically, the fixing base 2 can be provided with mounting holes, and the pressing component 4 is installed in the mounting holes. By pressing the pressing component 4, the pressing component 4 can be driven to move along the axial direction of the mounting holes.

[0058] In one embodiment, as Figure 3 and Figure 4 shown, the locking member 5 is provided with a plurality of limiting ends 501, and the plurality of limiting ends 501 are arranged at intervals. When a plurality of limiting ends 501 are provided on the locking member 5, a plurality of first card slots 101 are correspondingly provided on the cover 1. When a plurality of limiting ends 501 are provided on the locking member 5, in the locked state, the plurality of limiting ends 501 on the locking member 5 are respectively clamped in the corresponding first card slots 101, thereby enabling the cover 1 to be limited and fixed by the plurality of limiting ends 501, ensuring that the cover 1 is reliably locked in the locked state.

[0059] It can be understood that the locking member 5 can be provided with two limiting ends 501, or can be provided with three, four limiting ends 501, etc. In the embodiments of the present application, the number of the limiting ends 501 on the locking member 5 is not specifically limited.

[0060] In some embodiments, as Figure 4 shown, the locking member 5 is provided with two limiting ends 501, and the two limiting ends 501 are respectively arranged on both sides of the locking member 5.

[0061] In one embodiment, as Figure 4As shown, the top of the limiting end 501 is set as an inclined surface, which is inclined from the top surface to the bottom surface of the limiting end 501, from the end close to the elastic member 6 to the end far from the elastic member 6. By setting the top of the limiting end 501 as an inclined surface, when the cover body 1 is placed into the assembly groove 201, pressing the cover body 1 transmits the force received by the cover body 1 to the inclined surface of the limiting end 501. The inclined surface of the limiting end 501 is under pressure, causing the locking member 5 to move. The limiting end 501 enters the assembly hole 203 (as Figure 7 shown), so that the cover body 1 can be covered on the assembly groove 201.

[0062] Specifically, the inclined surface can be set as an arc surface or a plane. In the embodiment of the present application, the shape of the inclined surface is not specifically limited.

[0063] In one embodiment, as Figure 4 shown, the pressing assembly 4 includes a pressing member 401 and a pushing member 402. The pressing member 401 is fixedly connected to the pushing member 402. The pushing member 402 is in abutting contact with the locking member 5, and the abutting surface between the pushing member 402 and the locking member 5 is inclined. By fixedly connecting the pressing member 401 and the pushing member 402, applying pressure to the pressing member 401 causes the pressing member 401 to move, thereby driving the pushing member 402 to move. Since the pushing member 402 is in abutting contact with the locking member 5 and the abutting surface between the pushing member 402 and the locking member 5 is inclined, during the movement of the pushing member 402, the locking member 5 is pushed to move through the inclined abutting surface. During the movement of the locking member 5, it realizes the switching between the locked state and the unlocked state, so as to facilitate the locking and unlocking of the cover body 1.

[0064] Specifically, the pressing member 401 and the pushing member 402 can be connected by a connecting member 403. The connecting member 403 can be a bolt, a screw, etc. In the embodiment of the present application, the type of the connecting member 403 is not specifically limited.

[0065] It should be noted that the abutting surface between the pushing member 402 and the locking member 5 is inclined, resulting in different movements of the pushing member 402 and the locking member 5. For example, the moving direction of the pushing member 402 and the moving direction of the locking member 5 can be perpendicular to each other.

[0066] Specifically, the abutting surfaces of both the pushing member 402 and the locking member 5 can be inclined, or one of the pushing member 402 or the locking member 5 can be inclined. In the embodiment of the present application, the abutting surface is not specifically limited.

[0067] Specifically, the abutting surface can be set as an arc surface or a plane. In the embodiment of the present application, the inclination mode of the abutting surface is not specifically limited.

[0068] In one embodiment, as Figure 6As shown, a second card slot 202 is provided on the assembly groove 201, and the second card slot 202 is disposed opposite to the assembly hole 203 (as Figure 7 shown). A buckle (not shown in the figure) is provided on the cover body 1 corresponding to the second card slot 202. By providing the second card slot 202 in the assembly groove 201 and disposing the position of the second card slot 202 opposite to the assembly hole 203, when locking the cover body 1, it is necessary to first snap the buckle on the cover body 1 into the second card slot 202, and then press the cover body 1 so that the limiting end 501 snaps into the first card slot 101, thereby locking the cover body 1. By the limiting end 501 snapping into the first card slot 101 and the buckle snapping into the second card slot 202, the two ends of the cover body 1 are limited and fixed, ensuring that the cover body 1 is firmly locked on the assembly groove 201.

[0069] In the embodiment of the present application, the number of the second card slots 202 is not specifically limited.

[0070] Exemplarily, as Figure 6 shown, three second card slots 202 are provided at intervals on the assembly groove 201, then three buckles are provided on the cover body 1 corresponding to the second card slots 202. When the cover body 1 is locked, the three buckles are respectively snapped into the corresponding second card slots 202 to ensure that the cover body 1 is firmly locked.

[0071] Specifically, the second card slot 202 can be set as a rectangle, a square, a circle, etc.

[0072] In one embodiment, as Figure 3 and Figure 5 shown, it further includes a spring piece 7. One end of the spring piece 7 is fixedly provided on the cover body 1. In the locked state, the spring piece 7 is in a compressed state and the other end of the spring piece 7 abuts against the fixed seat 2; in the unlocked state, the spring piece 7 returns from the compressed state to the initial state, and applies an elastic force to the cover body 1 to make the cover body 1 pop out of the assembly groove 201. The other end of the spring piece 7 is abutted against the fixed seat 2. During the process of the cover body 1 switching from the locked state to the unlocked state, the limiting end 501 of the locking member 5 disengages from the first card slot 101 of the cover body 1. At this time, the cover body 1 is unlocked, and the spring piece 7 returns from the compressed state to the initial state, applying an elastic force in the direction away from the assembly groove 201 to the cover body 1, so that the cover body 1 pops out of the assembly groove 201, facilitating the user to take out the cover body 1.

[0073] Exemplarily, the spring piece 7 is a metal elastic member, and the spring piece 7 is in a long strip shape and is bent.

[0074] In one embodiment, as Figure 4As shown, two limiting pins 502 are respectively provided at two ends of the locking member 5, and one end of the elastic member 6 is sleeved on the limiting pin 502. By providing the limiting pin 502 on the locking member 5 and sleeving one end of the elastic member 6 on the limiting pin 502, the cooperation between the elastic member 6 and the locking member 5 is ensured to be stable, so that the elastic member 6 can provide a stable elastic force to the locking member 5, preventing the elastic member 6 from detaching from the locking member 5. At the same time, by providing the limiting pins 502 at two ends of the locking member 5 respectively and providing the elastic members 6 on each limiting pin 502 respectively, the elastic members 6 uniformly apply elastic forces to two ends of the locking member 5, ensuring that the elastic forces applied by the elastic members 6 to the locking member 5 can stably push the locking member 5 to move.

[0075] Specifically, the limiting pin 502 can be set to be cylindrical, or can be set to be a columnar shape with a cross-section of a cross shape. In the embodiment of the present application, the shape of the limiting pin 502 is not specifically limited.

[0076] In one embodiment, as Figure 4 shown, a guiding groove 503 is formed on the locking member 5, a guiding member 8 passing through the guiding groove 503 is provided on the fixed seat 2, a limiting block 9 is fixedly provided at the end of the guiding member 8, and the locking member 5 is arranged between the limiting block 9 and the fixed seat 2. By providing the guiding groove 503 on the locking member 5 and providing the guiding member 8 corresponding to the guiding groove 503 on the fixed seat 2, with the limiting block 9 fixed on the guiding member 8 and the locking member 5 arranged between the limiting block 9 and the fixed seat 2, it is ensured that the locking member 5 moves along the direction of the guiding groove 503, preventing the locking member 5 from shifting during the moving process.

[0077] In the embodiment of the present application, the number of the guiding grooves 503 provided on the locking member 5 is not specifically limited. Exemplarily, two guiding grooves 503 are provided at intervals on the locking member 5, and the two guiding grooves 503 are arranged in parallel.

[0078] In one embodiment, as Figure 5 shown, the battery locking device further includes at least one buffer member 10, and the buffer member 10 is arranged between the cover body 1 and the battery 3. By arranging the buffer member 10 between the cover body 1 and the battery 3, the buffer member 10 absorbs and disperses the energy from external impacts or vibrations, reducing the impact force on the battery 3, protecting the battery 3 from damage and extending the service life of the battery 3.

[0079] Specifically, the buffer member 10 can be selected from buffer rubber gaskets, buffer cotton, etc. In the embodiment of the present application, the type of the buffer member 10 is not specifically limited.

[0080] The working principle of the battery locking device in this embodiment is described as follows:

[0081] When installing the battery 3 in the assembly groove 201, it is necessary to cover the cover body 1 on the assembly groove 201. First, snap the buckle on one side of the cover body 1 into the second card slot 202, and then press the cover body 1. When the first card slot 101 of the cover body 1 is aligned with the assembly hole 203, the elastic member 6 exerts an elastic force on the locking member 5, pushing the locking member 5 to move, so that the limiting end 501 of the locking member 5 passes through the assembly hole 203 and is snapped into the first card slot 101. At this time, the cover body 1 is locked on the assembly groove 201, and the battery 3 is locked in the assembly groove 201. If the user needs to take out or replace the battery 3, only need to press the pressing assembly 4. The pressing assembly 4 overcomes the elastic force of the elastic member 6 so that the limiting end 501 of the locking member 5 falls off the first card slot 101. At this time, the cover body 1 is unlocked, and the elastic piece 7 on the cover body 1 switches from the compressed state to the initial state. The elastic piece 7 exerts an elastic force on the cover body 1 in the direction away from the assembly groove 201, pushing the cover body 1 out of the assembly groove 201. The user can then remove the cover body 1 and take out or replace the battery 3.

[0082] According to an embodiment of the present invention, on the other hand, an ultrasonic device is further provided, including a battery locking device.

[0083] For this ultrasonic device, the user can operate the cover body 1 of the battery 3 to switch between the locked state and the unlocked state with one hand, and at the same time avoid the phenomenon of jamming of the cover body 1 during the unlocking process. The structure is simple and easy to operate.

[0084] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
