Figure 2 is a schematic view of a vehicle-mounted battery pack locking mechanism according to the present application and a battery pack unlocked state. Figure 3 is Figure 2 is an enlarged view of the A region in FIG. Figure 4 is a schematic view of a vehicle-mounted battery pack locking mechanism according to the present application and a battery pack locked state. Figure 5 is Figure 4 is an enlarged view of the B region in FIG. Figures 1 to 5As shown, the vehicle-mounted battery pack locking mechanism of the present application is particularly suitable for large new energy vehicles equipped with large battery packs. The vehicle-mounted battery pack locking mechanism comprises a battery replacement channel and at least two locking assemblies 3. The battery replacement channel is used for the battery pack 4 to enter and exit the battery position 2 of the battery replacement vehicle 1 along the first direction. The bottom of the battery pack 4 is provided with a set of connecting rods 41 arranged in parallel along the first direction. The two ends of the connecting rod 41 are respectively provided with at least one second wedge block 42. The wedge slope surface of the second wedge block 42 extends along the first direction. Four locking assemblies 3 are respectively arranged at the two ends of the battery position 2 along the first direction. The locking assembly 3 at least comprises a first wedge block 31, a limiting sliding block 32, and a linear limiting assembly respectively arranged on the locking assembly 3 and the vehicle body. The limiting sliding block 32 is limited to linear motion only along the first direction. The first wedge block 31 is connected to one side of the limiting sliding block 32. The limiting sliding blocks 32 at both ends are respectively pushed towards the battery pack 4 by the biasing force. The wedge slope surfaces 38 of the first wedge blocks 31 are respectively in contact with the corresponding second wedge blocks 42 to self-lock, thereby bidirectionally limiting the battery pack 4 along the first direction. The two ends of each connecting rod 41 are respectively provided with second wedge blocks 42. The slope surface of the second wedge block 42 is exposed upwards. The slope surface of the first wedge block 31 is exposed downwards. The first direction is the width direction of the battery replacement vehicle 1. The slope surface of the first wedge block 31 and the slope surface of the second wedge block 42 are in contact with each other to self-lock. The locking force of the limiting sliding block 32 along the first direction is converted into a downward pressure on the battery pack 4 to the bottom plate of the battery position 2. The battery pack 4 is limited in the battery position 2 between the second wedge blocks 42 at both ends. The first direction is the width direction of the battery replacement vehicle 1. The linear limiting assembly comprises a dovetail groove 33 arranged at the bottom of the limiting sliding block 32 and a dovetail tenon 37 fixed in the battery position 2 in the vehicle body. The dovetail groove 33 slides along the dovetail tenon 37 based on the first direction. The first direction (Y direction, width direction of the vehicle body) is perpendicular to the length direction of the battery replacement vehicle 1 (X direction, length direction of the vehicle body). When the battery replacement is performed by the vehicle-mounted battery pack locking mechanism of the present application, the battery replacement robot 5 takes out the battery pack 4 from the container battery compartment 6 and inserts it into the battery position 2 of the battery replacement vehicle 1 along the width direction of the vehicle body. The battery pack 4 is firmly locked in the battery position 2 by the locking assembly 3, thereby avoiding the shaking of the vehicle in the vertical direction, the length direction and the width direction of the vehicle when the battery replacement vehicle 1 is running. In the present application, the cooperation between the dovetail groove 33 at the bottom of the limiting sliding block 32 and the dovetail tenon 37 fixed in the battery position 2 in the vehicle body can avoid the displacement of the limiting sliding block 32 in the vertical direction and the length direction of the vehicle. In combination with the biasing force and the self-locking of the wedge slope surface 38 of the first wedge block 31 and the second wedge block 42, the wedge angle of the slope surface 38 and the slope surface of the second wedge block 42 in the present application is in the range of 3° to 6° (but not limited to this range). The self-locking function is formed by the cooperation of the two wedge surfaces at such an angle, thereby effectively preventing the displacement of the limiting sliding block 32 in the width direction of the vehicle, thereby realizing the spatial locking of the battery pack 4.

[0066] In a preferred embodiment, when the cylinder 34 pulls the limiting slide block 32 towards the second wedge block 42, the cylinder 34 and the spring 36 form a resultant force to limit the battery pack 4, but not limited thereto.

[0067] In a preferred embodiment, the locking assembly 3 further comprises a cylinder 34, which drives the limiting slide block 32 to move in the first direction through the cylinder rod 35. The locking assembly 3 further comprises a spring 36, which pushes the limiting slide block 32 towards the second wedge block 42 of the battery pack 4. The spring 36 and the cylinder 34 are respectively distributed on both sides of the limiting slide block 32 in the first direction. Through the mutual cooperation of the wedge slope surface 38 of the first wedge block 31 and the slope surface of the second wedge block 42, the real-time locking force of the limiting slide block 32 in the first direction (which can be the resultant force of the cylinder 34 and the spring 36 to limit the battery pack 4, or the pushing force of the spring 36 alone to limit the battery pack 4) is converted into the downward pressure of the battery pack 4 to the bottom plate of the battery site 2. In the present application, the mechanical power of the cylinder 34 and the biasing force provided by the spring 36 enable the first wedge block 31 to firmly press the first wedge block 31, thereby achieving a double locking function. In the present embodiment, due to the cooperation between the first wedge block 31 and the second wedge block 42, when the cylinder 34 further increases the pulling force on the limiting slide block 32, the cooperation between the wedge blocks will provide greater downward pressure to the battery pack 4, thereby ensuring that the battery pack 4 is fixed in the battery site 2.

[0068] In a preferred embodiment, when the cylinder 34 pushes the limiting slide block 32 away from the second wedge block 42 against the pushing force of the spring 36, the battery site 2 is in an unlocked mode to put in or take out the battery pack 4, but not limited thereto.

[0069] In a preferred embodiment, the limiting slide blocks 32 are respectively located on the outer sides of the connecting rods 41, and the first wedge blocks 31 are respectively located on the opposite inner sides of the limiting slide blocks 32. The movement strokes of the first wedge blocks 31 are respectively located on the extension lines of the two ends of the connecting rods 41, but not limited thereto.

[0070] In a preferred embodiment, the battery site 2 is further provided with at least two vertically upward positioning guide rods (not shown in the figure). The battery pack 4 is first positioned in the vertical direction through the cooperation of its own vertical through hole (not shown in the figure) and the positioning guide rods, and then falls into the bottom of the battery site 2. Then, the limiting slide blocks 32 on both sides of the bottom of the battery site 2 clamp the second wedge block 42 through horizontal movement to fix the battery pack 4 in the horizontal plane. Through the cooperation between the vertical through hole, the positioning guide rods, the limiting slide blocks 32 and the second wedge block 42, the battery pack 4 is completely fixed on the battery site 2 in three-dimensional directions. At this time, the displacement stroke of the battery pack 4 in three-dimensional directions based on the battery site 2 is 0.

[0071] The vehicle-mounted battery pack locking system of the present application can lock the battery pack in space and provide double locking protection in the insertion direction of the battery pack, which can meet the requirement of quick opening and provide strong locking effect. The cylinder 34 can drive the first wedge block 31 to make a single reciprocating motion along the dovetail groove 33. The dovetail groove 33 not only plays a guiding role, but also can bear lateral force to prevent the first wedge block 31 from being out of the groove. And under the action of the cylinder 34, the first wedge block 31 and the second wedge block 42 are tightly fitted to realize the locking function. The inclined wedge clamping has the characteristics of simple structure, large force amplification ratio, good self-locking performance, etc., and is widely used. When the cylinder 34 fails to provide tension, the first wedge block 31 can still press the second wedge block 42 tightly under the rebound force of the spring 36 (for example, a compression spring). Therefore, the device has double locking function.

[0072] Based on the above technical features, the vehicle-mounted battery pack locking system of the present application has the following advantages:

[0073] 1. The cylinder is used for driving, and the power is simple.

[0074] 2. The structure layout is simple, horizontally arranged, and requires small installation space.

[0075] 3. The dovetail groove design effectively prevents loosening.

[0076] 4. The action is simple, and locking can be realized by single horizontal movement.

[0077] 5. Double protection is adopted, that is, a mechanical locking mechanism is added, and locking can also be realized by the rebound force of the spring in the case of cylinder failure.

[0078] Figure 6 is the flowchart of the vehicle-mounted battery pack locking method of the present application. As shown in Figure 6 , the vehicle-mounted battery pack locking method of the present application adopts the above-mentioned vehicle-mounted battery pack locking system, and includes the following steps:

[0079] S100, the battery pack 4 is limited in the battery position 2 by the vertical guide (for example, a positioning guide rod).

[0080] S110, the first wedge block 31 of the locking assembly 3 overcomes the biasing force and respectively leaves the second wedge block 42 of the two ends of the battery pack 4 unlocked.

[0081] S120, the battery pack 4 is lifted and leaves the battery position 2.

[0082] S130, another battery pack 4 is put into the battery position 2. and

[0083] S140, the first wedge block 31 of the locking assembly 3 is pressed to the second wedge block 42 at both ends of the battery pack 4, and the biasing force is combined to limit the battery pack 4 in the battery position 2.

[0084] Referring to Figures 1 to 5 The main process of the vehicle-mounted battery pack locking method of the embodiment of the present application is as follows:

[0085] When the battery pack is unlocked, the cylinder 34 provides a pushing force to overcome the elastic force of the spring 36, so that the first wedge block 31 and the second wedge block 42 are separated. After the battery pack is lifted by the battery replacement robot 5 and leaves the battery position 2, the battery replacement robot 5 enters the battery position 2 with another full battery pack 4 and lowers it. After the battery pack falls into the battery position 2 of the vehicle-mounted base, the system recognizes the signal and sends a command to the cylinder 34 to act. The moving wedge block 4 is pulled to the direction of the cylinder, the first wedge block 31 and the second wedge block 42 are tightly attached, and in this embodiment, when the wedge angle is less than 4.5 degrees, the wedge surface itself has a self-locking function, and the end spring is in an elastic state, realizing double locking function. Assuming that the cylinder 34 fails to provide a pulling force, under the action of the spring 36, the first wedge block 31 can still tightly press the second wedge block 42.

[0086] The vehicle-mounted battery pack locking method of the present application can spatially lock the battery pack and provide double locking protection in the insertion direction of the battery pack, which can meet the requirement of quick opening and provide strong locking effect.

[0087] The embodiment of the present application also provides a vehicle-mounted battery pack locking device, including a processor and a memory having executable instructions of the processor. The processor is configured to execute the steps of the vehicle-mounted battery pack locking method via the executable instructions.

[0088] As shown above, the vehicle-mounted battery pack locking system of the embodiment of the present application can spatially lock the battery pack and provide double locking protection in the insertion direction of the battery pack, which can meet the requirement of quick opening and provide strong locking effect.
