Technical Field

[0001] The utility model relates to the technical field of ultrasound, in particular to an ultrasound host and battery pack interlocking device and ultrasound equipment. Background Art

[0002] Ultrasound equipment refers to medical equipment that uses ultrasound for imaging, detection or treatment. By utilizing the characteristics of ultrasound, ultrasound equipment can provide non-invasive, real-time, radiation-free imaging, detection and treatment methods, bringing many advantages to the diagnosis, treatment and detection processes.

[0003] In the prior art, the interlocking button between the ultrasound host and the battery pack is usually set on the handle of the trolley, which can easily lead to misoperation and cause the precision instrument to fall. Some ultrasound host unlocking buttons are difficult to press, and are prone to getting stuck or being unable to be pressed during the unlocking process. There is even a phenomenon in which the ultrasound host and the battery pack are not locked in place and cannot be locked at the same time. Utility Model Content

[0004] In view of this, the utility model provides an interlocking device for an ultrasound host and a battery pack and an ultrasound device to solve the problem that the ultrasound host and the battery pack cannot be locked in place and cannot be locked at the same time.

[0005] In a first aspect, the present invention provides an interlocking device between an ultrasound host and a battery pack, comprising:

[0006] Ultrasound host;

[0007] A battery pack is detachably mounted on the bottom of the ultrasound host, wherein a first locking mechanism is provided in the battery pack for locking the battery pack and the ultrasound host;

[0008] A trolley is provided with an assembly slot, in which the battery pack is detachably arranged, and a second locking mechanism is provided in the trolley, the second locking mechanism being used to lock the ultrasound host on the trolley, and the second locking mechanism and the first locking mechanism both have a locked state and an unlocked state;

[0009] A handle is rotatably provided on the trolley, and the handle has an initial state and an open state;

[0010] In the initial state, the battery pack is arranged in the assembly slot and the ultrasound host is arranged on the top of the battery pack, the first locking mechanism is in the unlocked state and the second locking mechanism is in the locked state; the handle is forced to rotate from the initial state to the open state, the first locking mechanism is in the locked state and the second locking mechanism is in the unlocked state.

[0011] Beneficial effect: This ultrasound host and battery pack interlocking device locks the battery pack and the ultrasound host on the trolley. First, place the battery pack into the assembly slot of the trolley, and the first locking mechanism is in the unlocked state. Then, place the ultrasound host on top of the battery pack, and lock the ultrasound host on the trolley through the second locking mechanism, so that the ultrasound host and the battery pack are locked on the trolley together.

[0012] If it is necessary to remove the ultrasound host and battery pack from the trolley, external force is applied to the handle to rotate the handle from the initial state to the open state. At this time, the first locking mechanism is in the locked state, so that the battery pack and the ultrasound host are locked as one. The second locking mechanism is in the unlocked state, and the ultrasound host and the trolley are unlocked. The user can remove the ultrasound host from the trolley. Since the ultrasound host and the battery pack are locked as one by the first locking mechanism at this time, the battery pack can be removed together with the ultrasound host. If only the second locking mechanism is operated, only the ultrasound host can be unlocked and removed from the trolley, and the battery pack will remain on the trolley. By pulling the handle, the ultrasound host and the battery pack can be removed from the trolley together. The structure is simple and easy to operate, avoiding the phenomenon of the ultrasound host or battery getting stuck during the unlocking process.

[0013] In an optional embodiment, the first locking mechanism includes a pushing member, a first locking member and a first elastic member, the pushing member and the first locking member are both movably arranged in the battery pack, and the pushing member is arranged in abutment with the first locking member, one end of the first elastic member is fixed in the battery pack, and the other end is connected to the first locking member, the first elastic member applies an elastic force to the first locking member to move the first locking member toward the pushing member, a first limiting end is provided on the first locking member, a through hole is provided on the top surface of the battery pack, and a first slot is provided on the bottom surface of the ultrasound host corresponding to the first limiting end;

[0014] In the unlocked state of the first locking mechanism, the pushing member applies a thrust to the first locking member, causing the first elastic member to be compressed, and the first limiting end passes through the through hole and is located in the first card slot, and the first limiting end has no contact with the first card slot; in the locked state of the first locking mechanism, the first limiting end passes through the through hole and is engaged with the first card slot.

[0015] Beneficial Effect: When the battery pack is placed in the assembly slot, the handle applies a thrust to the pusher, causing the pusher to apply a thrust to the first locking member. This compresses the first elastic member, placing the ultrasound host on top of the battery pack. The first limiting end passes through the through-hole and is located within the first retaining slot, without contact with the first retaining end. When an external force is applied to the handle to pull it, the handle removes the thrust applied to the pusher, causing the first elastic member to return from its compressed state to its normal state. The first elastic member then applies an elastic force to the first locking member, causing it to move toward the pusher, causing the first limiting end on the first locking member to engage with the first retaining slot, thereby locking the battery pack and ultrasound host together.

[0016] In an optional embodiment, the contact surfaces of the pushing member and the first locking member are both inclined surfaces.

[0017] Beneficial effect: By setting the contact surface between the pushing member and the first locking member as an inclined surface, the moving path of the pushing member and the moving path of the first locking member are set at an angle.

[0018] In an optional embodiment, a guide groove is provided on the pushing member, and a guide column is provided in the battery pack corresponding to the guide groove, and the guide column passes through the guide groove.

[0019] Beneficial effect: by providing a guide groove on the pushing member, the guide groove cooperates with the guide column, so that the pushing member moves along the direction of the guide groove during the movement process, providing a guiding effect on the pushing member.

[0020] In an optional embodiment, the guide column is provided with a limit pin, the pusher is provided with a limit slot, the guide column is provided with a second elastic member, the guide column is adapted to move along its axial direction, and the bottom of the battery pack is provided with a through hole corresponding to the end of the guide column;

[0021] The trolley is provided with a protrusion corresponding to the through hole;

[0022] When the battery pack is arranged in the assembly slot, the protrusion pushes the guide column through the through hole, so that the limit pin is disengaged from the limit slot; when the battery pack is moved out of the assembly slot, the second elastic member applies elastic force to the limit pin to move the limit pin toward the limit slot, so that the limit pin is stuck in the limit slot, and the first locking mechanism is in the locked state.

[0023] Beneficial Effect: When the battery pack is placed in the assembly slot, the raised portion on the trolley passes through the perforation on the battery pack and pushes the guide column upward, causing the limit pin to disengage from the limit slot. The handle can then push the pusher, unlocking the first locking mechanism. When the battery pack is removed from the assembly slot, the second elastic member applies an elastic force to the limit pin, causing it to move toward the limit slot, locking it in the limit slot. The first locking mechanism is now locked, and the pusher is locked by the limit pin and cannot be pushed. This ensures that the battery pack is securely locked to the ultrasound host during battery removal, preventing the battery pack from becoming detached from the ultrasound host.

[0024] In an optional embodiment, the second locking mechanism includes a second locking member and a third elastic member, one end of the third elastic member abuts against the second locking member, and the other end is fixed to the trolley, the second locking member is movably arranged in the trolley, the ultrasound host is provided with a second slot, the trolley is provided with a through hole corresponding to the second slot, and the second locking member is provided with a second limiting end corresponding to the second slot;

[0025] In the locked state of the second locking mechanism, the third elastic member causes the second limiting end to pass through the through hole and be locked in the second slot, and the ultrasound host and the battery pack are locked on the trolley; in the unlocked state of the second locking mechanism, external force drives the second locking member to overcome the elastic force of the third elastic member, so that the second limiting end is disengaged from the second slot, and the ultrasound host is unlocked.

[0026] Beneficial Effect: When the ultrasound host and battery pack are installed on the trolley, the third elastic member applies an elastic force to the second locking mechanism toward the second slot, causing the second limiting end to pass through the through hole and lock into the second slot. The second limiting end engages with the second slot, and the ultrasound host and battery pack are now locked to the trolley. To unlock the ultrasound host, external force is applied to the handle, causing the handle to abut against the second locking mechanism, pushing the handle against the second locking mechanism, thereby moving the second locking mechanism away from the second slot, disengaging the second limiting end from the second slot, and unlocking the ultrasound host.

[0027] In an optional embodiment, the top of the second limiting end is inclined.

[0028] Beneficial effect: By setting an inclined surface at the top of the second limiting end, when the ultrasonic host is assembled on the trolley, the force received by the ultrasonic host is transferred to the inclined surface of the second limiting end by pressing the ultrasonic host. The inclined surface of the second limiting end is pressurized to cause the locking piece to move, so that the ultrasonic host can be locked on the trolley.

[0029] In an optional embodiment, the handle is provided with a rotating shaft, and the handle is rotated on the trolley via the rotating shaft. A first protrusion and a second protrusion are respectively provided on both sides of the handle, the first protrusion abuts against the first locking mechanism, and the second protrusion abuts against the second locking mechanism.

[0030] Beneficial effect: By respectively arranging the first protrusion and the second protrusion on both sides of the handle, the first protrusion abuts against the first locking mechanism to control the first locking mechanism to switch between the unlocked state and the locked state, and the second protrusion abuts against the second locking mechanism to control the second locking mechanism to switch between the unlocked state and the locked state. In summary, the first locking mechanism and the second locking mechanism can be controlled at the same time by controlling the handle, the structure is simple and easy to operate.

[0031] In an optional embodiment, a fourth elastic member is further included, one end of the fourth elastic member is fixed in the trolley, and the other end is connected to the handle. The fourth elastic member applies an elastic force to the handle, so that the handle is reset from the open state to the initial state under the action of the elastic force.

[0032] Beneficial effect: The fourth elastic member applies elastic force to the handle, so that the handle can be reset from the open state to the initial state under the action of the elastic force. After the user pulls the handle, the handle can automatically reset to the initial state when the handle is released.

[0033] In a second aspect, the present invention further provides an ultrasound device, comprising an ultrasound host and a battery pack interlocking device.

[0034] Beneficial effect: This ultrasound device can remove the ultrasound host and battery pack from the trolley together by pulling the handle. It has a simple structure and is easy to operate, avoiding the ultrasound host or battery from getting stuck during the unlocking process. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0059] In related technologies, the interlocking buttons of the ultrasound host and the battery pack are usually set on the handle of the trolley, which may easily lead to inoperability and cause the precision instrument to fall. Some ultrasound host unlocking buttons are difficult to press, and are prone to getting stuck or the buttons cannot be moved during the unlocking process. There is even a phenomenon that the ultrasound host and the battery pack cannot be locked in place and cannot be locked at the same time.

[0060] In order to solve the above technical problems, the following Figures 1 to 14 , describing the embodiments of the present utility model.

[0061] According to an embodiment of the present invention, on the one hand, an ultrasound host and battery pack interlocking device is provided, comprising an ultrasound host 1 , a battery pack 2 , a trolley 4 and a handle 6 .

[0062] Specifically, the battery pack 2 is detachably disposed at the bottom of the ultrasound host 1 , wherein a first locking mechanism 3 is provided in the battery pack 2 , and the battery pack 2 and the ultrasound host 1 are locked by the first locking mechanism 3 .

[0063] Specifically, the trolley 4 is provided with an assembly slot 401, in which the battery pack 2 is detachably mounted. The trolley 4 is provided with a second locking mechanism 5 for locking the ultrasound host 1 on the trolley 4. The second locking mechanism 5 and the first locking mechanism 3 both have a locked state and an unlocked state.

[0064] Specifically, the handle 6 is rotatably provided on the trolley 4 , and the handle 6 has an initial state and an open state.

[0065] In the initial state, the battery pack 2 is positioned within the assembly slot 401, and the ultrasound main unit 1 is positioned on top of the battery pack 2. The first locking mechanism 3 is unlocked, and the second locking mechanism 5 is locked. The handle 6 is forced to rotate from the initial state to the open state, with the first locking mechanism 3 locked and the second locking mechanism 5 unlocked.

[0066] This ultrasound host and battery pack interlocking device locks the battery pack 2 and the ultrasound host 1 on the trolley 4. First, place the battery pack 2 into the assembly slot 401 of the trolley 4, and the first locking mechanism 3 is in the unlocked state. Then, place the ultrasound host 1 on top of the battery pack 2, and lock the ultrasound host 1 on the trolley 4 through the second locking mechanism 5, so that the ultrasound host 1 and the battery pack 2 are locked on the trolley 4 together.

[0067] If it is necessary to remove the ultrasound host 1 and battery pack 2 from the trolley 4, an external force is applied to the handle 6 to rotate the handle 6 from the initial state to the open state. At this time, the first locking mechanism 3 is in the locked state, so that the battery pack 2 and the ultrasound host 1 are locked as a whole. The second locking mechanism 5 is in the unlocked state, and the ultrasound host 1 is unlocked from the trolley 4. The user can remove the ultrasound host 1 from the trolley 4. Since the ultrasound host 1 and the battery pack 2 are locked as a whole by the first locking mechanism 3, the battery pack 2 can be removed together with the ultrasound host 1. By pulling the handle 6, the ultrasound host 1 and the battery pack 2 can be removed from the trolley 4 together. The structure is simple and easy to operate, and it avoids the ultrasound host 1 or the battery from getting stuck during the unlocking process.

[0068] Specifically, if Figure 7 and Figure 8 As shown, a second clip 404 can be set in the assembly slot 401 of the trolley 4, and a fourth clip 203 is set on the battery pack 2 corresponding to the second clip 404. When the battery pack 2 is installed in the assembly slot 401, the second clip 404 and the fourth clip 203 are engaged to ensure that the battery pack 2 is fixed in the assembly slot 401. It should be noted that the positions of the second clip 404 and the fourth clip 203 can be interchanged. In the embodiment of the present application, the positions of the second clip 404 and the fourth clip 203 are not specifically limited.

[0069] Specifically, if Figures 4 to 6As shown, a first buckle 202 can be provided on the top surface of the battery pack 2, and a third card slot 103 is provided on the bottom surface of the ultrasound host 1 corresponding to the first buckle 202. When the ultrasound host 1 is installed on the battery pack 2, the first buckle 202 is engaged with the third card slot 103, so that the battery pack 2 is connected to the ultrasound host 1. It should be noted that the positions of the first buckle 202 and the third card slot 103 can be interchanged. In the embodiment of the present application, the positions of the first buckle 202 and the third card slot 103 are not specifically limited.

[0070] In one embodiment, Figure 9 and Figure 10 As shown, the first locking mechanism 3 includes a pushing member 301, a first locking member 302 and a first elastic member 303. The pushing member 301 and the first locking member 302 are both movably arranged in the battery pack 2, and the pushing member 301 is arranged in abutment with the first locking member 302. One end of the first elastic member 303 is fixed in the battery pack 2, and the other end of the first elastic member 303 is connected to the first locking member 302. The first elastic member 303 applies an elastic force to the first locking member 302 to move the first locking member 302 toward the pushing member 301. A first limiting end 3021 is provided on the first locking member 302, a through hole 201 is provided on the top surface of the battery pack 2, and a first card slot 101 (as shown in FIG. 101 ) is provided on the bottom surface of the ultrasound host 1 corresponding to the first limiting end 3021. Figure 5 shown).

[0071] When the first locking mechanism 3 is unlocked, the pushing member 301 applies a thrust to the first locking member 302 (the handle 6 can be used to apply a thrust to the pushing member 301, thereby causing the pushing member 301 to apply a thrust to the first locking member 302), compressing the first elastic member 303. The first limiting end 3021 passes through the through hole 201 and is located in the first engaging groove 101. The first limiting end 3021 does not contact the first engaging groove 101. When the first locking mechanism 3 is locked, the first limiting end 3021 passes through the through hole 201 and is engaged with the first engaging groove 101.

[0072] When the battery pack 2 is placed in the assembly slot 401, the handle 6 applies a thrust to the pusher 301, causing the pusher 301 to apply a thrust to the first locking member 302. At this point, the first elastic member 303 is compressed, placing the ultrasound host 1 on top of the battery pack 2. The first limiting end 3021 passes through the through hole 201 and is located in the first engaging slot 101, with no contact between the first limiting end 3021 and the first engaging slot 101. When an external force is applied to the handle 6 to pull it, the handle 6 removes the thrust applied to the pusher 301, and the first elastic member 303 returns from its compressed state to its normal state. The first elastic member 303 applies an elastic force to the first locking member 302, causing it to move toward the pusher 301, causing the first limiting end 3021 on the first locking member 302 to engage with the first engaging slot 101, thereby locking the battery pack 2 and the ultrasound host 1 together.

[0073] In one embodiment, Figure 10 As shown, the contact surfaces of the pusher 301 and the first locking member 302 are both inclined surfaces 3011. By setting the contact surfaces of the pusher 301 and the first locking member 302 as the inclined surfaces 3011, the moving paths of the pusher 301 and the first locking member 302 are set at an angle.

[0074] Specifically, the inclined surface 3011 can be set to a 45° inclined surface 3011, and the moving path of the push member 301 and the moving path of the first locking member 302 can be perpendicular to each other. In the embodiment of the present application, the inclination angle of the inclined surface 3011 is not specifically limited.

[0075] In one embodiment, Figure 12 As shown, a guide slot 3012 is formed on the pusher 301, and a guide post 304 is provided in the battery pack 2 corresponding to the guide slot 3012. The guide post 304 passes through the guide slot 3012. By providing the guide slot 3012 on the pusher 301, the guide slot 3012 cooperates with the guide post 304, so that the pusher 301 moves along the direction of the guide slot 3012 during movement, providing guidance for the pusher 301.

[0076] Specifically, the direction of the guide groove 3012 can be set along the length direction of the pushing member 301. In the embodiment of the present application, the direction of the guide groove 3012 is not specifically limited.

[0077] In one embodiment, combined Figures 10 to 12 As shown, the guide post 304 is provided with a limit pin 3041, the pusher 301 is provided with a limit slot 3013, and the guide post 304 is provided with a second elastic member 305. The guide post 304 is adapted to move axially along the guide post 304. The bottom of the battery pack 2 is provided with a through-hole 204 corresponding to the end of the guide post 304, and the trolley 4 is provided with a protrusion 402 corresponding to the through-hole 204. When the battery pack 2 is positioned within the assembly slot 401, the protrusion 402 passes through the through-hole 204 and pushes the guide post 304, causing the limit pin 3041 to disengage from the limit slot 3013. When the battery pack 2 is removed from the assembly slot 401, the second elastic member 305 applies an elastic force to the limit pin 3041, causing it to move toward the limit slot 3013, causing the limit pin 3041 to be locked within the limit slot 3013, and the first locking mechanism 3 is in the locked state.

[0078] When the battery pack 2 is placed in the assembly slot 401, the protrusion 402 on the trolley 4 will pass through the through-hole 204 on the battery pack 2 and push the guide column 304 upward, causing the limit pin 3041 to disengage from the limit slot 3013. At this time, the handle 6 can push the pusher 301, and the first locking mechanism 3 is unlocked. When the battery pack 2 is removed from the assembly slot 401, the second elastic member 305 applies an elastic force to the limit pin 3041, causing the limit pin 3041 to move toward the limit slot 3013, causing the limit pin 3041 to be stuck in the limit slot 3013. At this time, the first locking mechanism 3 is in a locked state, and the pusher 301 is locked by the limit pin 3041 and cannot be pushed. This ensures that the battery pack 2 is firmly locked to the ultrasound host 1 during the battery removal process, preventing the battery pack 2 from being separated from the ultrasound host 1.

[0079] In one embodiment, Figure 13 As shown, the second locking mechanism 5 includes a second locking member 501 and a third elastic member 502. One end of the third elastic member 502 abuts against the second locking member 501, and the other end of the third elastic member 502 is fixed on the trolley 4. The second locking member 501 is movably arranged in the trolley 4. The ultrasound host 1 is provided with a second card slot 102 (as shown in FIG. Figure 3 As shown), a through hole 403 is provided on the trolley 4 corresponding to the second slot 102 (as shown Figure 8 As shown), a second limiting end 5012 is provided on the second locking member 501 corresponding to the second slot 102.

[0080] When the second locking mechanism 5 is locked, the second limiting end 5012 of the third elastic member 502 passes through the through hole 403 and is locked in the second locking slot 102, locking the ultrasound host 1 and the battery pack 2 to the trolley 4. When the second locking mechanism 5 is unlocked, an external force drives the second locking member 501 to overcome the elastic force of the third elastic member 502, causing the second limiting end 5012 to disengage from the second locking slot 102, thereby unlocking the ultrasound host 1.

[0081] When the ultrasound host 1 and the battery pack 2 are installed on the trolley 4, the third elastic member 502 applies an elastic force to the second locking mechanism 5 in the direction of the second engaging slot 102, causing the second limiting end 5012 to pass through the through hole 403 and be locked in the second engaging slot 102. The second limiting end 5012 engages with the second engaging slot 102, and the ultrasound host 1 and the battery pack 2 are now locked on the trolley 4. If it is necessary to unlock the ultrasound host 1, an external force is applied to the handle 6, causing the handle 6 to abut against the second locking mechanism 5, causing the handle 6 to apply a thrust to the second locking mechanism 5, thereby moving the second locking mechanism 5 away from the second engaging slot 102, causing the second limiting end 5012 to disengage from the second engaging slot 102. At this time, the ultrasound host 1 is unlocked.

[0082] In one embodiment, Figure 13As shown, the top of the second limit end 5012 is set to be inclined. By setting an inclined surface on the top of the second limit end 5012, when the ultrasound host 1 is assembled on the trolley 4, the force received by the ultrasound host 1 is transferred to the inclined surface of the second limit end 5012 by pressing the ultrasound host 1. The inclined surface of the second limit end 5012 is subjected to pressure, causing the locking piece to move, so that the ultrasound host 1 is locked on the trolley 4.

[0083] In one embodiment, Figure 14 As shown, the handle 6 is provided with a rotation shaft 601, and the handle 6 is rotatably mounted on the trolley 4 via the rotation shaft 601. A first protrusion 602 and a second protrusion 603 are respectively provided on either side of the handle 6. The first protrusion 602 abuts the first locking mechanism 3, and the second protrusion 603 abuts the second locking mechanism 5. Providing the rotation shaft 601 on the handle 6 facilitates the rotation of the handle 6 on the trolley 4. By providing the first protrusion 602 and the second protrusion 603 on either side of the handle 6, the first protrusion 602 abuts the first locking mechanism 3 to control the first locking mechanism 3 to switch between an unlocked state and a locked state, while the second protrusion 603 abuts the second locking mechanism 5 to control the second locking mechanism 5 to switch between an unlocked state and a locked state. In summary, the first locking mechanism 3 and the second locking mechanism 5 can be simultaneously controlled by controlling the handle 6, resulting in a simple structure and easy operation.
