[0001] This utility model relates to the field of new energy battery technology, specifically to a guide locking mechanism and a battery swapping box locking device. Background Technology

[0002] Against the backdrop of vigorously promoting sustainable development, the new energy vehicle industry is booming, and battery swapping technology is also constantly improving. For battery swapping, the positioning and locking of the battery pack is crucial.

[0003] In existing technologies, locking and unlocking actions are accomplished by extending and retracting the drive rod of a double-acting power cylinder via a hydraulic or pneumatic power source. However, when the pressure source malfunctions or is lost during transmission through pipeline accessories, resulting in insufficient pressure, the double-acting power cylinder cannot achieve battery locking. Utility Model Content

[0004] In view of this, the present invention provides a guide locking mechanism and a battery swapping box locking device to solve the problem that the existing double-acting power cylinder cannot lock the battery when the pressure source fails or the pressure is insufficient.

[0005] In a first aspect, this utility model provides a guide locking mechanism, comprising: a power cylinder and a locking pin; the power cylinder includes a drive rod, a one-way power source, and a power spring, the one-way power source and the power spring being tractively connected to the drive rod and adapted to drive the drive rod to move in opposite directions; the locking pin is connected to the drive end of the drive rod, the locking pin having an abutment surface formed on a first side along the vertical direction, the end of the locking pin away from the drive rod being a first end, the abutment surface being disposed near the first end, and the abutment surface being adapted to abut against a battery box; the locking pin includes an unlocked position and a locked position, the locking pin shifting from the locked position to the unlocked position, and the power spring storing energy; the power spring releasing energy drives the drive rod and causes the locking pin to shift from the unlocked position to the locked position, and the abutment surface abuts against the battery box.

[0006] Beneficial effects: The battery box is locked by extending the drive rod and locking pin through the release of energy from the power spring. When the pressure source fails or the pressure is insufficient, the battery box can still be locked by the pushing force of the power spring on the drive rod and locking pin. The battery box is unlocked by retracting the locking pin.

[0007] In one optional embodiment, the power cylinder further includes a cylinder body with a cavity formed therein. The drive rod is telescopically disposed within the cavity, dividing the cavity into a rod-side cavity and a rodless cavity. The power spring is disposed within the rodless cavity, with one end of the power spring connected to the end of the drive rod away from the locking pin, and the other end of the power spring connected to the cavity wall of the rodless cavity.

The first guide slope is inclined from the first end to the second end in a direction away from the abutment surface. The first guide slope is adapted to slide abut against the battery box.

[0009] Beneficial effects: During the battery swapping process, if a pressure source failure or insufficient pressure occurs, the battery box can be locked by pressing down the locking pin when the battery falls. The battery box slides against the inclined surface of the first wire, and the locking pin retracts inward until it reaches the unlocked position. The battery box is then installed in place, and the locking pin pops out under the action of the power spring, thus locking the battery box during the swapping process.

[0010] In one optional embodiment, the guide locking mechanism has an unlocked state; in the unlocked state, the unidirectional power source drives the drive rod and moves the locking pin from the locked position to the unlocked position; or, in the unlocked state, the first guide ramp is adapted to slidably abut against the battery box, and under the action of the abutment force applied by the battery box, drives the locking pin from the locked position to the unlocked position; or, in the unlocked state, the first guide ramp is adapted to slidably abut against the battery box, and under the combined action of the abutment force applied by the battery box and the driving force applied by the unidirectional power source, drives the locking pin from the locked position to the unlocked position.

[0011] In one alternative embodiment, in the locked position, the power spring has a certain amount of residual potential energy, so that the abutment surface continuously applies an abutment force to the battery box.

[0012] Beneficial effect: When in the locked position, the power spring has a certain residual potential energy, which ensures that the power spring always maintains a thrust on the drive rod, thereby ensuring that the battery box is locked securely.

[0013] In one optional embodiment, the guide locking mechanism further includes a guide structure having a second guide ramp formed thereon, the second guide ramp being adapted to slide against the battery box, the first guide ramp and the second guide ramp having the same inclination direction.

[0014] Beneficial effects: During the battery swapping process, the second guide ramp of the guide structure enables the initial guidance and positioning of the battery box, improving work efficiency.

[0015] In one optional embodiment, the guide structure has a guide groove, the locking pin is slidably disposed in the guide groove, the guide locking mechanism further includes a mounting base, the mounting base is connected to the guide structure, and the power cylinder is connected to the mounting base.

[0016] Beneficial effects: By placing the locking pin and power cylinder on the wire structure, the structural layout of the guide locking mechanism is optimized, making the structure of the guide locking mechanism compact and reducing the space occupied by the guide locking mechanism.

[0017] Secondly, this utility model also provides a battery swapping box locking device, including: the above-mentioned guide locking mechanism and device base; the device base has a first direction and a second direction, and a plurality of guide locking mechanisms are provided, the plurality of guide locking mechanisms being spaced apart on the device base along the first direction and / or the second direction.

[0018] Beneficial effects: By having several guide locking mechanisms spaced apart along the first and second directions on the device base, the battery box can be quickly guided and positioned, facilitating rapid battery replacement.

[0019] In one optional embodiment, the battery swapping box locking device further includes a shock-absorbing component and an electrical connector. The shock-absorbing component is disposed on the device base, and the electrical connector is disposed on the shock-absorbing component and is adapted to be plugged into the battery box.

The electrical connector is connected to the upper mounting plate, the lower mounting plate is connected to the device base, the upper mounting plate and the lower mounting plate are spaced apart, and the buffer spring is connected and disposed between the upper mounting plate and the lower mounting plate.

[0021] Beneficial effect: By installing a buffer spring between the upper and lower mounting plates, the buffer spring absorbs the displacement caused by vehicle bumps, preventing damage to the electrical connector. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, in a first aspect, a guide locking mechanism is provided, comprising: a power cylinder 10 and a locking pin 20; the power cylinder 10 includes a drive rod 11, a one-way power source, and a power spring 12, both of which are connected to the drive rod 11 and adapted to drive the drive rod 11 to move in opposite directions; the locking pin 20 is connected to the drive end of the drive rod 11, and a first side of the locking pin 20 along the vertical direction Z forms an abutment surface 21, the end of the locking pin 20 away from the drive rod 11 is the first end, the abutment surface 21 is disposed near the first end, and the abutment surface 21 is adapted to abut against the battery box 100; the locking pin 20 includes an unlocked position and a locked position, the locking pin 20 moves from the locked position to the unlocked position, and the power spring 12 stores energy; the power spring 12 releases energy to drive the drive rod 11 and move the locking pin 20 from the unlocked position to the locked position, and the abutment surface 21 abuts against the battery box 100.

[0036] The guide locking mechanism of this embodiment locks the battery box 100 by releasing the energy of the power spring 12 to drive the drive rod 11 and the locking pin 20 to extend. When the pressure source fails or the pressure is insufficient, the power spring 12 can still push the drive rod 11 and the locking pin 20 to ensure the locking of the battery box 100. The battery box 100 is unlocked by retracting the locking pin 20.

[0037] Specifically, such as Figure 5 As shown, the abutment surface 21 is formed on the lower side of the locking pin 20.

[0038] It should be noted that in related technologies, a double-acting cylinder is often used to control the movement of the drive rod 11. For a double-acting cylinder, the air source supplies air to the rod chamber 1311 and the rodless chamber 1312 of the cylinder respectively to achieve the retraction and extension of the drive rod. However, when the air source leaks or malfunctions, the rod chamber 1311 or the rodless chamber 1312 may not have a stable pressure supply, causing the drive rod 11 to fail to move normally. More seriously, after the battery box 100 is locked, when the pressure in the rodless chamber 1312 drops and the pressure in the rod chamber 1311 is greater than the pressure in the rodless chamber 1312, the drive rod 11 may retract under the influence of the pressure difference, which may lead to the failure of the battery box 100 to lock, creating a safety hazard.

[0039] In this embodiment, the power cylinder 10 is a single-acting cylinder. The air source only supplies air to the rod chamber 1311. The retraction movement of the drive rod 11 is achieved by the air supply, while the extension of the drive rod 11 is achieved by the energy release of the power spring 12. The power spring 12 can continuously provide thrust to the drive rod 11. Even if the air source leaks or malfunctions, the power spring 12 can still ensure that the locking pin 20 remains in the locked position, ensuring safe operation of the vehicle when powered on.

[0040] It should be noted that when the locking pin 20 releases its contact with the battery box 100 without affecting the removal of the battery box 100, the battery box 100 is considered to be fully unlocked, and the position of the locking pin 20 at this time is the unlocked position; when the locking pin 20 reaches a point of continuous contact with the battery box 100, the battery box 100 is considered to be locked in place, and the position of the locking pin 20 at this time is the locked position.

[0041] In one embodiment, such as Figure 5 As shown, the power cylinder 10 also includes a cylinder body 13, in which a cavity 131 is formed. The drive rod 11 is telescopically disposed in the cavity 131, dividing the cavity 131 into a rod chamber 1311 and a rodless chamber 1312. The power spring 12 is disposed in the rodless chamber 1312. One end of the power spring 12 is connected to the end of the drive rod 11 away from the locking pin 20, and the other end of the power spring 12 is connected to the cavity wall of the rodless chamber 1312.

[0042] In one embodiment, such as Figure 5 As shown, the locking pin 20 has a first guide slope 22 formed on its second side along the vertical direction Z. The first guide slope 22 is set near the first end, and the end of the locking pin 20 near the drive rod 11 is the second end. The first guide slope 22 is inclined from the first end to the second end in a direction away from the abutment surface 21. The first guide slope 22 is suitable for sliding abutment with the battery box 100.

[0043] Specifically, such as Figure 5 As shown, the first guide slope 22 is formed on the upper side of the locking pin 20.

[0044] It should be noted that during the battery swapping process of the battery box 100, if a pressure source failure or insufficient pressure occurs, the battery box 100 can be locked by pressing down the locking pin 20 when the battery falls. The battery box 100 slides against the inclined surface of the first wire, and the locking pin 20 retracts inward until it reaches the unlocked position. The battery box 100 is then installed in place, and the locking pin 20 pops out under the action of the power spring 12, thus locking the battery box 100 during the swapping process.

[0045] In one embodiment, the guide locking mechanism has an unlocked state.

[0046] Specifically, in the first embodiment, in the unlocked state, the unidirectional power source drives the drive rod 11 and causes the locking pin 20 to move from the locked position to the unlocked position.

[0047] It should be noted that the first implementation method is the conventional unlocking method.

[0048] In the second embodiment, in the unlocked state, the first guide ramp 22 is adapted to slidably abut against the battery box 100, and under the action of the abutment force applied by the battery box 100, it drives the locking pin 20 to move from the locked position to the unlocked position.

[0049] It should be noted that the second implementation method is an emergency unlocking method or an emergency battery installation method.

[0050] In the third embodiment, in the unlocked state, the first guide ramp 22 is adapted to slidably abut against the battery box 100. Under the combined action of the abutment force applied by the battery box 100 and the driving force applied by the unidirectional power source, the drive lock stop pin 20 is transferred from the locked position to the unlocked position.

[0051] In one embodiment, in the locked position, the power spring 12 has a certain residual potential energy so that the abutment surface 21 continuously applies an abutment force to the battery box 100.

[0052] It is worth noting that when in the locked position, the power spring 12 has a certain residual potential energy, which ensures that the power spring 12 always maintains a thrust on the drive rod 11, thereby ensuring that the locking pin 20 and the battery box 100 are firmly locked.

[0053] In one embodiment, such as Figures 1 to 5 As shown, the guide locking mechanism also includes a guide structure 30, on which a second guide slope 31 is formed. The second guide slope 31 is adapted to slide against the battery box 100. The first guide slope 22 and the second guide slope 31 have the same inclination direction. During the battery swapping process, the second guide slope 31 of the guide structure 30 achieves initial guidance and positioning of the battery box 100, improving work efficiency.

[0054] In one embodiment, such as Figure 1 As shown, the guide structure 30 has a guide groove 32, and the locking pin 20 is slidably disposed in the guide groove 32. The guide locking mechanism also includes a mounting base 40, which is connected to the guide structure 30, and the power cylinder 10 is connected to the mounting base 40. By placing the locking pin 20 and the power cylinder 10 on the guide wire structure, the structural layout of the guide locking mechanism is optimized, making the structure of the guide locking mechanism compact and reducing the space occupied by the guide locking mechanism.

[0055] Specifically, the cylinder block 13 is connected to the mounting base 40.

[0056] It should be noted that in related technologies, the battery box 100 is positioned, guided, and locked by simultaneously setting a guide structure 30 and a locking structure on the main body of the device. However, the structural layout of such positioning and locking devices is not compact and occupies a large amount of space. Therefore, in this embodiment, the locking pin 20 and the power cylinder 10 are integrated on the guide structure 30, saving the space occupied by the locking mechanism.

[0057] According to an embodiment of the present invention, in a second aspect, a battery swapping box locking device is also provided, comprising: the aforementioned guide locking mechanism and a device base 50; the device base 50 has a first direction X and a second direction Y, and a plurality of guide locking mechanisms are provided, which are spaced apart on the device base 50 along the first direction X and / or the second direction Y. By having a plurality of guide locking mechanisms spaced apart on the device base 50 along the first direction X and the second direction Y, rapid guiding and positioning of the battery box 100 is achieved, facilitating rapid battery swapping.

[0058] Specifically, such as Figure 1 and Figure 2 As shown, multiple guide locking mechanisms are provided along the first direction X and the second direction Y to increase the positioning accuracy of the device base 50 to the battery box 100.

[0059] In one embodiment, such as Figure 7 and Figure 8 As shown, the battery box locking device also includes a shock-absorbing component 60 and an electrical connector 70. The shock-absorbing component 60 is disposed on the device base 50, and the electrical connector 70 is disposed on the shock-absorbing component 60. The electrical connector 70 is adapted to be plugged into the battery box 100.

[0060] In one embodiment, such as Figure 8 As shown, the shock absorption assembly 60 includes an upper mounting plate 61, a lower mounting plate 62, and a buffer spring 63. An electrical connector 70 is connected to the upper mounting plate 61, and the lower mounting plate 62 is connected to the device base 50. The upper mounting plate 61 and the lower mounting plate 62 are spaced apart, and the buffer spring 63 is connected and disposed between the upper mounting plate 61 and the lower mounting plate 62.

[0061] It should be noted that the connector pin of the battery box 100 is continuously engaged with the electrical connector 70 on the device base 50. Vibrations occur during vehicle operation. Without a damping structure, the connector pin or electrical connector 70 of the battery box 100 may be damaged, or even disconnected, posing a safety hazard. Therefore, this application places a buffer spring 63 between the upper mounting plate 61 and the lower mounting plate 62 to form a damping structure, reducing the impact of vibration on the connector pin and electrical connector 70 of the battery box 100.

[0062] In one embodiment, such as Figure 8As shown, the shock absorption assembly 60 also includes a limiting boss 64, which is disposed on the upper mounting plate 61 and the lower mounting plate 62. The buffer spring 63 is sleeved on the limiting boss 64. By setting the limiting boss 64, the buffer spring 63 is limited, preventing the buffer spring 63 from bending or shifting, which would cause the buffer spring 63 to be damaged and fail.

[0063] Specifically, such as Figure 8 As shown, there are two limiting bosses 64. The two limiting bosses 64 are detachably mounted on the upper mounting plate 61 and the lower mounting plate 62 respectively by fasteners. The two limiting bosses 64 are arranged opposite each other in the vertical direction Z.

[0064] It should be noted that the two limiting bosses 64 are arranged opposite each other along the vertical Z direction, and during vibration, the two limiting bosses 64 move towards each other. When the two limiting bosses 64 abut each other, it is the maximum deformation of the buffer spring 63. Therefore, the limiting bosses 64 can also limit the maximum deformation of the buffer spring 63.

[0065] Of course, in other alternative embodiments, the limiting boss 64 may also be provided only on the upper mounting plate 61 or the lower mounting plate 62. When the limiting boss 64 is provided on the upper mounting plate 61, during vibration, the limiting boss 64 abuts against the lower mounting plate 62 to limit the maximum deformation of the buffer spring 63; when the limiting boss 64 is provided on the lower mounting plate 62, during vibration, the limiting boss 64 abuts against the upper mounting plate 61 to limit the maximum deformation of the buffer spring 63.

[0066] Specifically, such as Figure 8 As shown, the damping assembly 60 also includes a guide rod 65, which is arranged vertically in the Z direction. One end of the guide rod 65 is fixed to the lower mounting plate 62, and the upper mounting plate 61 has a guide hole. The other end of the guide rod 65 is adapted to pass through the guide hole. By providing the guide rod 65, the relative displacement between the upper mounting plate 61 and the lower mounting plate 62 can be guided.

[0067] Furthermore, the limiting boss 64 has a through hole along the vertical direction Z, which is connected to the guide hole. The guide rod 65 is slidably inserted in the through hole to provide guidance for the buffer spring 63.

[0068] In one embodiment, such as Figure 1 As shown, the battery swapping box locking device also includes a guide post 80, which is disposed on the device base 50 and is adapted to be inserted into the guide positioning hole of the battery box 100.

[0069] It is worth noting that by setting the guide post 80, the positioning accuracy of the battery box 100 by the battery box locking device is further improved.

[0070] In one embodiment, such as Figure 1 As shown, the battery swapping box locking device also includes a foolproof pin 90, which is provided at any corner of the device base 50. The foolproof pin 90 is adapted to be inserted into the foolproof positioning hole of the battery box 100.

[0071] It should be noted that the foolproof pin 90 should not be placed on the center line of the first direction X or the second direction Y, so as to avoid the foolproofing failure.

[0072] It is worth noting that by setting the anti-foolproof pin 90, the left-right or front-back position of the battery box 100 is reversed during the lowering process, which could damage the electrical connector 70; and the battery box 100 is prevented from being placed on an incompatible battery swapping box locking device.

[0073] Although 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 spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
