The locking mechanism is usually a pin-type locking mechanism, which typically uses a cylinder to drive the locking pin so that the locking pin is inserted into the lock hole at the bottom of the battery box.

[0004] However, the locking reliability of the pin-type locking mechanism is low. Wear or deformation of the lock hole can cause the lock to loosen, which in turn causes the battery box to bounce along its height during vehicle operation. Utility Model Content

[0005] This utility model provides a battery box locking mechanism, a battery swapping system, and a vehicle, aiming to at least solve the technical problem of low locking reliability of the existing pin-type locking mechanism, wear or deformation of the lock hole, which can lead to loosening of the lock and cause the battery box to bounce along its height direction during vehicle operation.

[0006] In the first aspect, this utility model provides a battery box locking mechanism, which is mounted on the main frame of a vehicle base, the vehicle base being used for mounting the battery box;

[0007] The battery box locking mechanism includes a pressure block, a mounting base, a telescopic drive component, and a connecting shaft. The middle part of the pressure block is rotatably connected to the mounting base, and the pressure block has a pressing surface.

[0008] The end of the pressure block away from the pressing surface has a through groove, the connecting shaft passes through the through groove, the telescopic drive is connected to the connecting shaft, the telescopic drive is arranged horizontally, and the telescopic direction of the telescopic drive is perpendicular to the axial direction of the connecting shaft.

[0009] The telescopic drive is used to drive the connecting shaft to move, and the movement of the connecting shaft causes the pressure block to rotate, so that the pressing surface presses against or disengages from the locking surface in the battery box.

[0010] Optionally, the mounting base includes two opposing side plates, and the pressure block is located between the two side plates;

[0011] Guide grooves are provided on both side plates. The length direction of the guide grooves is parallel to the extension direction of the telescopic drive. The two ends of the connecting shaft are respectively connected to the two guide grooves by two rollers.

[0014] Optionally, a pin is hinged to the middle of the pressure block, and the two ends of the pin are respectively connected to the two side plates.

[0015] Optionally, the battery box locking mechanism further includes a connecting bracket, the connecting bracket including a first connecting portion connected to the telescopic drive member;

[0022] Thirdly, this utility model provides a vehicle including the battery swapping system described above.

[0023] In this embodiment of the invention, when the pressing surface of the pressure block presses against the locking surface of the battery box, the telescopic drive component remains in operation, causing the pressure block to tend to rotate downwards. This ensures that the pressure block maintains pressure on the locking surface, resulting in high locking reliability and preventing loosening of the lock. This also prevents the battery box from jumping along its height due to loosening after locking. Furthermore, in this embodiment, the large contact area between the pressure block and the locking surface of the battery box reduces contact stress, thereby slowing down wear on the pressure block and the locking surface. Even after prolonged operation and slight wear on the pressure block and locking surface, the continuous operation of the telescopic drive component and the downward rotation tendency of the pressure block ensure that it can still press against the locking surface, maintaining locking reliability. Additionally, the horizontal arrangement of the telescopic drive component optimizes the force distribution on the component, preventing wear and avoiding cylinder leakage when the telescopic drive component is a cylinder.

Detailed Implementation

[0034] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] Currently, battery bases typically have locking mechanisms for locking and unlocking the battery box. These mechanisms are usually pin-type, where a cylinder drives the locking pin to insert it into a locking hole at the bottom of the battery box. However, pin-type locking mechanisms have low reliability; wear or deformation of the locking hole can cause the lock to loosen, resulting in the battery box bouncing along its height during vehicle operation. To address these issues, this invention provides a battery box locking mechanism, a battery swapping system, and a vehicle. The following is a detailed description of the aforementioned battery box locking mechanism, battery swapping system, and vehicle.

[0036] Firstly, referring to Figures 1 to 7This utility model provides a battery box locking mechanism 1, which is mounted on the main frame 2 of a vehicle chassis for mounting the battery box. The battery box locking mechanism 1 includes a pressing block 104, a mounting base 106, a telescopic drive member 101, and a connecting shaft 103. The middle part of the pressing block 104 is rotatably connected to the mounting base 106, and the pressing block 104 has a pressing surface 1041. A through slot 1042 is provided at the end of the pressing block 104 away from the pressing surface 1041, and the connecting shaft 103 passes through the through slot 1042. The telescopic drive member 101 is connected to the connecting shaft 103. The telescopic drive member 101 is arranged horizontally, and the telescopic direction of the telescopic drive member 101 is perpendicular to the axial direction of the connecting shaft 103. The telescopic drive member 101 is used to drive the connecting shaft 103 to move. The movement of the connecting shaft 103 drives the pressing block 104 to rotate, so that the pressing surface 1041 presses against or disengages from the locking surface 601 in the battery box.

[0037] The vehicle-mounted underbody is mounted on the vehicle and specifically fixed to the vehicle's main beam. The connection between the underbody and the main beam is typically via bolts. The battery box is mounted on the underbody. Preferably, the battery box is inserted into the underbody. The underbody includes a main frame 2 and the aforementioned battery box locking mechanism 1. The connection between the battery box locking mechanism 1 and the main frame 2 can be via bolts, welding, or other methods.

[0038] Mounting base 106 is connected to main frame 2. Battery box locking mechanism 1 is an independent mechanism, and the number of battery box locking mechanisms 1 in the vehicle base can be set according to actual needs, such as four, six, eight, etc. The middle part of pressure block 104 can be rotatably connected to mounting base 106 through pin 105. The shape of the cross section of through groove 1042 perpendicular to its extension direction can be waist-shaped, arc-shaped, etc. The shape of the cross section of connecting shaft 103 perpendicular to its axis direction is circular. Battery box includes box frame and mating components set on box frame. Locking surface 601 is located on locking plate 6 in mating components, and pressing surface 1041 is specifically used to press against locking surface 601 in locking plate 6.

[0039] The telescopic drive component 101 can be a cylinder, hydraulic cylinder, electric actuator, etc. Preferably, the telescopic drive component 101 is a cylinder, in which case the power source can be provided by onboard compressed air. The telescopic direction of the telescopic drive component 101 can be referred to... Figure 1 and Figure 2 As indicated by arrow B, the telescopic drive 101 extends in a direction parallel to the width of the mounting base 106. The battery box locking mechanism 1 also includes an inner mounting plate 1064. The telescopic drive 101 can be connected to the inner mounting plate 1064 via a mounting block 108. The connection between the mounting block 108 and the inner mounting plate 1064 can be a bolt connection.

[0040] Mounting base 106 includes two opposing side plates 1061, with pressure block 104 located between the two side plates 1061. Mounting base 106 also includes an outer baffle 1063 connected to the two side plates 1061. The outer baffle 1063 is specifically connected to the side of the two side plates 1061 away from the telescopic drive member 101, and is close to the locking surface 601. An external through groove is provided on the outer baffle 1063 for the pressure block 104 to pass through.

[0041] The pressure block 104 has a locked state and an unlocked state. Figure 1 , Figure 3 , Figure 4 In the middle, the pressure block 104 is in the locked state. At this time, the pressure block 104 protrudes from the mounting base 106, and the pressing surface 1041 presses against the locking surface 601 in the battery box. Figure 2 and Figure 6 In the middle, the pressure block 104 is in the unlocked state. At this time, the pressing surface 1041 is located inside the mounting base 106, and the pressing surface 1041 is disengaged from the locking surface 601 in the battery box. When the pressure block 104 rotates from the locked state to the unlocked state, the end of the pressure block 104 near the pressing surface 1041 passes through the outer through groove to rotate into the mounting base 106.

[0042] When the pressure block 104 is in the unlocked state, to move it to the locked state, the connecting shaft 103 needs to be driven by the telescopic drive member 101 to move away from the locking surface 601 along the telescopic direction of the telescopic drive member 101, that is, away from the outer baffle 1063. The movement of the connecting shaft 103 causes the end of the pressure block 104 away from the pressing surface 1041 to rotate away from the locking surface 601. At this time, the end of the pressure block 104 near the pressing surface 1041 rotates towards the locking surface 601, so that the pressure block 104 rotates to the locked state. When the pressure block 104 rotates to the locked state, the telescopic drive member 101 will remain running. At this time, the pressure block 104 will have a downward rotation tendency, and the pressure block 104 will keep pressing against the locking surface 601.

[0043] In this embodiment of the invention, when the pressing surface 1041 of the pressing block 104 presses against the locking surface 601 in the battery box, the telescopic drive member 101 remains in operation, causing the pressing block 104 to tend to rotate downwards. This ensures that the pressing block 104 keeps pressing against the locking surface 601, resulting in high locking reliability and preventing loosening of the lock. Consequently, it prevents the battery box from jumping along its height direction due to loosening after locking. Furthermore, in this embodiment, the contact area between the pressing block 104 and the locking surface 601 in the battery box is large, which reduces contact stress and thus slows down the wear of the pressing block 104 and the locking surface 601. In addition, even after long-term operation, if the pressing block 104 and the locking surface 601 show slight wear, the pressing block 104 can still press against the locking surface 601 due to the continuous operation of the telescopic drive member 101 and the downward rotation tendency of the pressing block 104, ensuring locking reliability. Furthermore, the horizontal arrangement of the telescopic drive component 101 optimizes the stress on it, prevents wear, and avoids air leakage when the telescopic drive component 101 is a cylinder. In addition, the battery box locking mechanism 1 has a simple structure, low manufacturing cost, and is easy to install and maintain.

[0044] In an optional embodiment of this utility model, guide grooves 1066 are provided on both side plates 1061. The length direction of the guide grooves 1066 is parallel to the extension direction of the telescopic drive member 101. The two ends of the connecting shaft 103 are respectively connected to the two guide grooves 1066 by two rollers 107.

[0045] The two side plates 1061 are arranged opposite each other along the length of the mounting base 106, and the length of the mounting base 106 can be referred to as Figure 3 The direction indicated by arrow C. A connecting groove 1067, which communicates with the guide groove 1066, is also provided on the side plate 1061 for the connecting shaft 103 to pass through. A bushing 111 can be fitted onto the connecting shaft 103, and the bushing 111 can be located between the connecting groove 1067 and the connecting shaft 103. The bushing 111 can be an oil-free bushing. The mounting base 106 also includes a base plate 1065 connected to the two side plates 1061, and the base plate 1065 is bolted to the main frame 2.

[0046] When the telescopic drive member 101 drives the connecting shaft 103 to move away from the locking surface 601 along the telescopic direction of the telescopic drive member 101, the roller 107 specifically rolls in the guide groove 1066 in the direction away from the locking surface 601. When the telescopic drive member 101 drives the connecting shaft 103 to move towards the locking surface 601 along the telescopic direction of the telescopic drive member 101, the roller 107 specifically rolls towards the locking surface 601 in the guide groove 1066. In this embodiment, the movement of the connecting shaft 103 can be either a simple movement or a rolling motion that occurs along with the rolling of the roller 107.

[0047] The connecting shaft 103 has a first end and a second end. The second end of the connecting shaft 103 may have a threaded section, on which a nut 109 is threadedly connected. The nut 109 is located on the side of the roller 107 mounted on the second end of the connecting shaft 103 away from the mounting base 106. The connecting shaft 103 can be removed after unscrewing the nut 109 and the roller 107 mounted on the second end of the connecting shaft 103.

[0048] In this embodiment, the guide groove 1066 restricts the movement trajectory of the roller 107 and the connecting shaft 103, enabling them to run along a predetermined trajectory and preventing the connecting shaft 103 from deviating from the predetermined trajectory during movement.

[0049] In an optional embodiment of the present invention, the mounting base 106 serves as a coarse guide, and each side plate 1061 has a first coarse guide surface for coarse guidance; the mounting base 106 also includes an inclined guide plate 1062 connected between the two side plates 1061, and the inclined guide plate 1062 has a second coarse guide surface for coarse guidance.

[0050] Specifically, the first coarse guide surface is the outer surface of the side plate 1061, and the second coarse guide surface is the outer surface of the inclined guide plate 1062. The mounting seats 106 that provide coarse guidance are typically arranged in pairs, and the two mounting seats 106 in a pair are symmetrically arranged. In this embodiment, the mounting seats 106 provide coarse guidance, eliminating the need for additional coarse guide blocks and simplifying the structure of the vehicle chassis.

[0051] In an optional embodiment of this utility model, a pin 105 is hinged to the middle of the pressure block 104, and both ends of the pin 105 are respectively connected to two side plates 1061. The cross-section of the pin 105 perpendicular to its axial direction is circular. The end of the pin 105 has a threaded section. Mounting holes are provided on both side plates 1061. When installing the pin 105, the end of the pin 105 passes through the two mounting holes in sequence and is threadedly connected to the locking nut 110.

[0052] In an optional embodiment of the present invention, the battery box locking mechanism 1 further includes a connecting bracket 102, the connecting bracket 102 including a first connecting part 1021 connected to the telescopic drive member 101; the connecting bracket 102 also includes two second connecting parts 1022 connected to the first connecting part 1021, a through groove 1042 located between the two second connecting parts 1022, each of the two second connecting parts 1022 having a shaft hole, and a connecting shaft 103 passing through the through groove 1042 and the two shaft holes.

[0053] The connecting bracket 102 can be Y-shaped. The telescopic drive component 101 includes a drive component housing 1011 and a telescopic rod 1012, with the first connecting part 1021 specifically connected to the telescopic rod 1012. The connection between the first connecting part 1021 and the telescopic rod 1012 can be detachable. Two second connecting parts 1022 are located on both sides of the pressure block 104 along the length of the mounting base 106. The connecting shaft 103 is clearance-fitted with the shaft hole on the second connecting part 1022.

[0054] In an optional embodiment of the present invention, the cross-section of the through groove 1042 perpendicular to the extension direction of the through groove 1042 is waist-shaped, and the two ends of the waist shape in the length direction are close to the middle of the pressure block 104 and the end of the pressure block 104 away from the pressing surface 1041, respectively.

[0055] The working principle of the battery box locking mechanism 1 described above can be summarized as follows:

[0056] Press block 104 is Figure 2 The unlock state shown has switched to Figure 1 When the locking state is shown, the telescopic rod 1012 in the telescopic drive 101 is retracted. At this time, the connecting bracket 102 moves away from the locking surface 601 along the telescopic direction of the telescopic drive 101. The movement of the connecting bracket 102 drives the connecting shaft 103 to move. The movement of the connecting shaft 103 drives the end of the pressure block 104 away from the pressing surface 1041 to rotate away from the locking surface 601. At this time, the end of the pressure block 104 near the pressing surface 1041 rotates toward the locking surface 601 so that the pressure block 104 rotates to the locking state.

[0057] Press block 104 is Figure 1 The locked state shown has switched to Figure 2 When the unlocked state is shown, the telescopic rod 1012 in the telescopic drive 101 extends. At this time, the connecting bracket 102 moves toward the locking surface 601 along the telescopic direction of the telescopic drive 101. The movement of the connecting bracket 102 drives the connecting shaft 103 to move. The movement of the connecting shaft 103 drives the end of the pressure block 104 away from the pressing surface 1041 to rotate toward the locking surface 601. At this time, the end of the pressure block 104 near the pressing surface 1041 rotates away from the locking surface 601, so that the pressure block 104 rotates to the unlocked state.

[0058] It should be noted that the movement of the connecting shaft 103 can be either a simple movement or a rolling movement that occurs along with the rolling of the roller 107.

[0059] Secondly, this utility model provides a battery swapping system, including a battery box and a vehicle base. The vehicle base includes a main frame 2, and at least one battery box locking mechanism 1 provided in the first aspect is provided on the main frame 2.

[0060] The number of battery box locking mechanisms 1 in the vehicle chassis can be set according to actual needs, such as four, six, or eight. Since the battery swapping system includes the aforementioned battery box locking mechanism 1, it also possesses the beneficial effects of the aforementioned battery box locking mechanism 1, which will not be elaborated here.

[0061] In an optional embodiment of the present invention, the battery box includes a box frame and at least one mating component disposed at the bottom of the box frame. The mating component includes a fixing seat 5 disposed on the box frame and a locking plate 6 detachably connected to the fixing seat 5. The locking surface 601 in the battery box is located on the locking plate 6.

[0062] The box frame includes a bottom beam 4 located at the bottom, with supporting components specifically mounted on the bottom beam 4. The mounting base 5 can be welded to the bottom beam 4. The locking plate 6 can be connected to the mounting base 5 via bolts, snap-fit, or other methods. In this embodiment, the locking plate 6 is detachably connected to the mounting base 5, facilitating maintenance or replacement of the locking plate 6.

[0063] The main frame 2 has a bearing surface for supporting the battery box. When the battery box is installed on the vehicle chassis, the bottom surface of the bottom beam 4 of the battery box frame contacts the bearing surface on the main frame 2. For different battery boxes, the thickness of the bottom beam 4 of the battery box frame may vary. In this case, by replacing the locking plate 6 with one of different thicknesses, the distance in the height direction between the locking surface 601 and the bottom surface of the bottom beam 4 of the battery box frame can remain unchanged. This allows the battery box locking mechanism 1 to be used with different battery boxes, improving its compatibility.

[0064] In an optional embodiment of this utility model, a battery swapping connector is also provided on the main frame 2; a plurality of precision guide pins 3 are also provided on the main frame 2, and the plurality of precision guide pins 3 are located around the battery swapping connector.

[0065] The battery swapping connector is used for electrical connection with the connector at the bottom of the battery box. The number of precision guide pins 3 can be set according to actual needs, such as two, four, or six. Preferably, there are four precision guide pins 3, which surround the battery swapping connector. When the battery box is installed on the vehicle chassis, the mounting base 106 provides initial guidance, and the precision guide pins 3 provide precise guidance to the battery box, ensuring a high-precision connection between the battery box and the vehicle chassis.

[0066] Thirdly, this utility model embodiment provides a vehicle that includes the battery swapping system provided in the second aspect.

[0067] The battery box is replaced according to the battery level. When replacing the battery box, a fully charged battery box in the battery swapping station can be automatically replaced by a battery swapping robot to replace the low-charge battery box in the vehicle, so as to achieve rapid energy replenishment.

[0068] Methods for replacing the battery pack in a vehicle may include:

[0069] S1, When the battery box in the vehicle has low power and needs to be replaced, the vehicle drives to the battery swapping station. After information identification, it stops at the designated battery swapping location with the assistance of the guidance and positioning device. After the driver turns off the vehicle and disconnects the power, the lower-level computer in the vehicle receives the instruction from the upper-level computer in the vehicle and controls the battery box locking mechanism 1 to unlock. When the battery box locking mechanism 1 unlocks, the telescopic rod 1012 in the telescopic drive member 101 extends. During this process, the connecting bracket 102 moves towards the locking surface 601 along the telescopic direction of the telescopic drive member 101. The movement of the connecting bracket 102 drives the connecting shaft 103 to move. The movement of the connecting shaft 103 drives the end of the pressure block 104 away from the pressing surface 1041 to rotate towards the locking surface 601. At this time, the end of the pressure block 104 near the pressing surface 1041 rotates away from the locking surface 601. S2, When the telescopic rod 1012 in the telescopic drive member 101 is fully extended, the pressure block 104 is in the unlocked state. S3, The battery swapping robot moves to the battery swapping vehicle. Above or to the side, the depleted battery box is lifted or removed, and then the fully charged battery box in the battery swapping station is lifted onto the vehicle base; S4, when the fully charged battery box is placed on the vehicle base, the host computer sends a command to control the battery box locking mechanism 1 to perform a locking action. When the battery box locking mechanism 1 performs the locking action, the telescopic rod 1012 in the telescopic drive 101 retracts. During this process, the connecting bracket 102 moves away from the locking surface 601 along the telescopic drive 101's telescopic direction. The movement of the bracket 102 drives the connecting shaft 103 to move. The movement of the connecting shaft 103 drives the end of the pressure block 104 away from the pressing surface 1041 to rotate away from the locking surface 601. At this time, the end of the pressure block 104 close to the pressing surface 1041 rotates towards the locking surface 601. S5, when the telescopic rod 1012 in the telescopic drive member 101 retracts to the set position, the pressure block 104 is in the locked state, and the battery swapping is completed. S6, after the vehicle is powered on and started, it can leave the battery swapping station with a fully charged battery box.
