Description

Technical Field

[0001] This application relates to the field of battery swapping technology, and in particular to a battery locking mechanism and a battery base. Background Technology

[0002] Currently, in the field of electromechanical equipment, a technology for quick battery replacement has been developed, enabling rapid power replenishment. Specifically, a battery base is installed on the electromechanical equipment, and a battery locking mechanism is installed on the battery base. This mechanism can lock or unlock the battery box. When the battery box is depleted, the battery locking mechanism can unlock the battery box, facilitating its transfer using specialized lifting equipment. The lifting equipment then picks up a fully charged battery box and loads it onto the battery base, where the battery locking mechanism can lock the battery box again. By installing a battery base on the electromechanical equipment, battery replacement and maintenance costs are reduced.

[0003] In related technologies, a battery base includes a base frame and a battery locking mechanism mounted on the base frame. The battery locking mechanism typically includes a guide body, a pin, and a cylinder. The guide body has a through groove, and the pin is slidably mounted in the through groove. The cylinder is located outside the guide body, and the cylinder and pin are in a driving relationship to drive the pin to slide out or retract along the through groove to perform locking or unlocking tasks. When the pin is engaged with the battery compartment, when an external force is applied to the pin, the pin tends to retract. When the external force is large enough, the pin may retract and detach from the battery compartment, causing the battery locking structure to fail and creating a safety hazard of the battery compartment falling off or tipping over.

[0023] Optionally, a guide body is provided on the base body, the guide body having a cavity and a telescopic opening communicating with the cavity;

[0024] The second extension is pivotally connected to the guide, and the locking member is at least partially located in the cavity, while the telescopic assembly is located outside the cavity;

[0046] Example 1

[0047] like Figures 1 to 4 As shown in the figure, this application provides a battery locking mechanism, including: a locking member 1, a telescopic assembly 2, and a connecting rod 3. The locking member 1 has a locking tongue 11, a first extension 12, and a second extension 13. The first extension 12 protrudes to the side opposite to the locking tongue 11. The extension length of the second extension 13 is greater than that of the first extension 12, which facilitates connection to the base body 200 of the battery base. The ends of the first extension 12 and the second extension 13 are both rotatably connected. The telescopic assembly 2 has a telescopic member 21, which can translate linearly. One end of the connecting rod 3 is hinged to the telescopic member 21, and the other end of the connecting rod 3 is hinged to the first extension 12. The telescopic movement of the telescopic member 21 can drive the locking member 1 to swing through the connecting rod 3, so that the locking tongue 11 moves to the locked position or the unlocked position. In the state where the locking tongue 11 moves to the locked position, the telescopic directions of the connecting rod 3 and the telescopic member 21 are perpendicular, and the moving direction of the telescopic member 21 is consistent with the extending direction of the second extension 13.

[0048] When the latch 11 is moved to the locked position, the extension and retraction directions of the connecting rod 3 and the telescopic member 21 are perpendicular. When an external force is applied to the latch 11, the locking member 1 transmits the force to the connecting rod 3. Since the connecting rod 3 and the telescopic member 21 are perpendicular to each other and in a self-locking state, the telescopic member 21 will not move back. The locking member 1 remains in the locked state and will not be easily unlocked, thereby improving security.

[0049] like Figure 1 As shown, the battery locking mechanism may consist of only a locking element 1, a connecting rod 3, and a telescopic assembly 2. Figure 3As shown, the battery locking mechanism may also include at least two locking elements 1. The telescopic element 21 includes a telescopic part 21a and a synchronous frame 21b. The telescopic part 21a is connected to the synchronous frame 21b, and the synchronous frame 21b is connected to each of the locking elements 1 via connecting rods 3. The telescopic part 21a can telescopically move, driving each of the locking elements 1 to swing through the synchronous frame 21b. Taking a battery locking mechanism including two locking elements 1 as an example, the telescopic part 21a can be a rod, and the synchronous frame 21b is perpendicular to the telescopic part 21a, with both ends of the synchronous frame 21b connected to the corresponding locking element 1 via connecting rods 3.

[0050] In some possible implementations, the battery locking mechanism includes a guide sleeve 4, the telescopic assembly 2 includes a telescopic drive member 22, the guide sleeve 4 is connected to the telescopic drive member 22, the telescopic member 21 is slidably inserted through the guide sleeve 4, and the telescopic drive member 22 and the telescopic member 21 are drively connected to drive the telescopic member 21 to slide along the guide sleeve 4.

[0051] In this embodiment, the guide sleeve 4 can be fixed to the base body 200 or guide body 300 of the battery base, which can restrict the movement trajectory of the telescopic member 21, so that the telescopic member 21 can only move in a straight line.

[0052] In some possible implementations, such as Figure 4 As shown, the guide sleeve 4 includes an outer sleeve 41 and an inner sleeve 42. The outer sleeve 41 is fitted onto the inner sleeve 42. A lubrication groove 421 is provided on the inner wall of the inner sleeve 42, and an oil injection groove is provided on the outer wall of the inner sleeve 42. The oil injection groove and the lubrication groove 421 are connected. The oil injection groove can be an annular groove provided on the outer wall of the inner sleeve 42. An opening is provided in the annular groove along the radial direction of the inner sleeve 42 to connect with the lubrication groove 421. An oil injection port 411 is provided on the outer sleeve 41 to connect with the oil injection groove. The telescopic member 21 is slidably inserted into the inner sleeve 42. Lubricating oil can be injected into the oil injection groove through the oil injection port 411. The lubricating oil will eventually enter the lubrication groove 421 on the inner wall of the inner sleeve 42, which helps to reduce the sliding resistance of the telescopic member 21.

[0053] In some possible implementations, the telescopic member 21 has a slot 211 and a connecting groove 212. The slot 211 extends along the telescopic direction of the telescopic member 21, and the connecting groove 212 is perpendicular to the telescopic direction of the telescopic member 21 and communicates with the slot 211. The telescopic drive member 22 includes a main body and a telescopic shaft 222 connected to the main body. The telescopic shaft 222 is inserted into the slot 211, and a pin passes through the connecting groove 212 and through the telescopic shaft 222. The telescopic drive member 22 can be a cylinder, with the main housing being the cylinder body and the telescopic shaft 222 being the movable shaft of the cylinder. The end of the movable shaft of the cylinder is inserted into the telescopic member 21 and connected to the telescopic member 21 by a pin.

[0054] In some possible implementations, such as Figure 2 As shown, the telescopic drive component 22 has a telescopic shaft 222, a cylindrical shell, a front end plate 221, and a rear end plate. The front end plate 221 and the rear end plate are respectively connected to both ends of the cylindrical shell and respectively close the ports at both ends of the cylindrical shell. The telescopic shaft 222 is slidably connected to the cylindrical shell and is disposed through the front end plate 221. The front end plate 221 has a transition part, which is used for connection and fixation.

[0055] Optionally, such as Figure 2 and Figure 3 As shown, the front end plate 221 includes an end plate portion, and the adapter portion includes two adapter arms 2211. The end plate portion is connected to the cylindrical shell, and both adapter arms 2211 of the adapter portion are connected to the end plate portion. There is a gap between the two adapter arms 2211 to avoid the locking member 1. The adapter arms 2211 are used for connection and fixation, such as welding to the guide body.

[0056] In some possible implementations, such as Figure 4 As shown, the locking mechanism includes an elastic element 23, which can be a spring, sleeved on the telescopic shaft 222, with its two ends abutting against the main body and the telescopic member 21, respectively. When gas is injected into the cylinder, it drives the telescopic shaft 222 to move downward, the locking member 1 is in the unlocked state, and the elastic element 23 is in the compressed state. When the cylinder deflates, the elastic element 23 returns to its original deformation, pushing the telescopic member 21 upward, causing the locking member 1 to swing to the locked position.

[0057] Example 2

[0058] like Figures 1 to 4 As shown, Embodiment 2 of this application also provides a battery base, including: a base body 200 and the aforementioned battery locking mechanism. The second extension 13 of the locking member 1 of the battery locking mechanism is rotatably connected to the base body 200, and the telescopic component 2 of the battery locking mechanism is disposed on the base body 200, with the telescopic direction of the telescopic member 21 perpendicular to the base body 200.

[0059] In some possible implementations, a guide body 300 is provided on the base body 200. The guide body 300 has a cavity and a telescopic opening 320 communicating with the cavity. A second extension 13 is pivotally connected to the guide body 300, and the locking member 1 is at least partially located in the cavity. The telescopic assembly 2 is located outside the cavity. When the latch 11 is moved to the locked position, the latch 11 extends out of the telescopic opening 320. When the latch 11 is moved to the unlocked position, the latch 11 is located inside the cavity and does not extend out of the telescopic opening 320.

[0060] In some possible implementations, the guide body 300 has a side opening 310 on the side opposite to the telescopic opening 320 to avoid the locking member 1. The side opening 310 has a narrow section 312 and a wide section 311. The narrow section 312 is located on both sides of the wide section 311. The first extension 12 and the connecting rod 3 are connected by a pin. During the swinging of the locking member 1, the pin can pass through the wide section 311. The design of the wide section 311 avoids the pin between the first extension 12 and the connecting rod 3, ensuring that the locking member 1 swings smoothly.

[0061] In some possible implementations, the two adapter arms 2211 of the telescopic drive member 22 are respectively connected to the guide body 300, and the two adapter arms 2211 are located on both sides of the swing plane of the second extension 13. The swing plane is a plane perpendicular to the swing axis of the second extension 13, which is the plane where the locking member 1 swings. The two connecting arms avoid the second extension 13, so that the locking member 1 swings smoothly without interference.

[0062] In some possible implementation schemes, combined Figures 1 to 3 As shown, the battery locking mechanism includes a first battery locking mechanism 100a and a second battery locking mechanism 100b. The first battery locking mechanism 100a is disposed at one end of the base body 200 along the length direction and includes one locking member 1. For example, a first battery locking mechanism 100a can be disposed at each end of the base body 200 along the length direction. The second battery locking mechanism 100b includes a telescopic component 2 and two locking members 1. The two locking members 1 are disposed on both sides of the base body 200 along the width direction. The telescopic component 21 of the telescopic component 2 of the second battery locking mechanism 100b is connected to the two locking members 1 by a connecting rod 3. The telescopic component 21 moves up and down, which can simultaneously drive the two locking members 1 to swing. The battery base can be provided with two second battery locking mechanisms 100b, which are arranged sequentially along the length direction of the base body.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
