Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a clamping and locking mechanism. Background Technology

[0002] The energy system of a battery swapping vehicle mainly consists of a battery box assembly for storing electrical energy and a base for fixing the battery box. The base is equipped with a locking mechanism for clamping and releasing the battery box. When the locking mechanism clamps, it locks the battery box and the base, keeping their installation position fixed. When the locking mechanism unlocks, the battery box is lifted off the base by the hoisting equipment to perform the battery swapping operation.

[0003] Even when operating at full capacity, existing battery-swapping vehicles have a very limited frequency of battery swapping, so there is no need to design a particularly complex locking mechanism that would result in a bulky structure.

[0004] Because existing clamping and locking mechanisms cannot adaptively adjust their position, they are prone to frequent jamming and are unreliable, often requiring manual intervention.

[0005] There is an urgent need for a clamping and unlocking mechanism that can adaptively adjust its position to avoid frequent jamming. Utility Model Content

Detailed Implementation

[0043] The present invention will be further described below with reference to the accompanying drawings.

[0044] See Figures 1 to 6 Specific Embodiment 1: A clamping and locking mechanism with adaptive position adjustment includes a locking pin 11 and a power assembly 30 that drives the locking pin 11 to extend and retract. The power assembly 30 is a telescopic cylinder, and the cylinder body is hinged to a power base 40. A second perforated positioning rod 31 passes through the tail of the power assembly 30 and the mounting hole of the power base 40, and a second cotter pin 32 passes through the locking pin hole of the second perforated positioning rod 31 to fix it. Limiting protrusions and locking pin holes are respectively provided at both ends of the second perforated positioning rod 31.

[0045] The locking pin 11 consists of a guide portion with increasing cross-section along the axial direction, a pin body, and a connecting portion for connecting the telescopic cylinder. The connecting portion has a mounting hole for inserting the telescopic rod 33 of the telescopic cylinder, and the connecting portion is hinged to the telescopic rod 33. A hinge gap exists between the telescopic rod of the telescopic cylinder and the locking pin. It also includes a pin sleeve 20 for adjusting the position of the locking pin, in which the locking pin 11 slides. A position adjustment gap exists between the locking pin 11 and the pin sleeve 20. The telescopic movement of the telescopic cylinder causes the guide portion of the locking pin 11 to extend out of the pin sleeve 20 and retract into it. This invention optimizes the clamping and locking mechanism, facilitating the alignment and extension of the locking pin 11 through the limiting hole after fine-tuning its position in the telescopic direction, thus achieving adaptive adjustment of the insertion position.

[0046] The power seat and the pin sleeve are fixedly positioned relative to each other.

[0047] The pin sleeve 20 is a circular tube structure. The pin body is a cylindrical structure.

[0048] It also includes a baffle 21 that limits the extension length of the locking pin. The baffle 21 has a limiting hole for the guide portion to pass through, and the limiting hole is directly opposite the inner hole of the pin sleeve. The outer wall of the guide portion near the pin body includes an upper cylindrical surface and a lower cylindrical surface, which are connected by mutually parallel tangents. The limiting hole matches the outer wall of the guide portion near the pin body.

[0049] Both the connecting part and the telescopic rod 33 of the telescopic cylinder are provided with locking pin holes. The locking pin holes of the connecting part and the telescopic rod 33 of the telescopic cylinder pass through the first perforated positioning rod 12, and the positioning hole of the first perforated positioning rod 12 passes through the first cotter pin 13. This facilitates the hinge connection between the locking pin 11 and the telescopic rod 33 of the telescopic cylinder. The two ends of the first perforated positioning rod 12 are respectively provided with limiting bosses and positioning holes. The outer wall of the connecting part has concave cuts to avoid the first cotter pin 13 and concave notches to avoid the limiting boss at the end of the first driving positioning rod. The first perforated positioning rod 12 and the second perforated positioning rod 31 are parallel in axis.

[0050] The guide section has mirror-symmetrical inclined surfaces on its upper and lower sides; a limiting step is provided at the connection between the guide section and the pin; the end face of the limiting step is used to abut against the baffle 21.

[0051] The axial projection area of ​​the limiting hole is located inside the axial projection area of ​​the pin.

[0052] The position adjustment gap is 0.05mm-0.10mm.

[0053] The hinge clearance between the telescopic rod 33 and the locking pin 11 of the telescopic cylinder is 0.10mm-0.20mm.

[0054] It also includes a base 23, on which a power seat 40 is fixed; a locking seat 22 is fixed on the base 23, and a baffle 21 is fixed to the outer side of the locking seat 22, and a pin sleeve 20 is installed on the locking seat 22. Two locking seats 22 are installed on the long side of the base 23, and one locking seat 22 is installed on the short side of the base 23; the power seat 40 is arranged in a one-to-one correspondence with the locking seat 22. A vertically arranged column and a horizontally arranged crossbar are fixed on the base 23. One side of the top of the column is fixedly connected to the crossbar, and a power seat 40 is fixed on the other side of the column; two more power seats 40 are installed on the opposite side of the end of the crossbar away from the column. The system redundancy design of six locking seats limits improves the robustness of the mechanism. The outer side of the locking seat 22 is a guide surface that slopes downward from the inside to the outside and a vertically arranged limiting surface. A baffle 21 is fixed on the limiting surface.

[0055] It also includes a power battery pack assembly 50; the power battery pack assembly 50 is provided with a locking ramp 51 corresponding to the position of the locking seat 22, and the upper surface of the locking ramp 51 matches the lower surface of the guide portion. The base support 23 is provided with a support frame; the power battery pack assembly 50 is provided with a bottom frame, which is located above the support frame and outside the locking seat 22; the locking ramp 51 is fixed to the top of the bottom frame.

[0056] When the locking mechanism clamps, the power battery pack assembly 50 is placed downwards along the Z-direction on the base 23. Under the thrust of the power component 30, the locking pin 11 on the base 23 moves radially outwards along the inner cavity of the pin sleeve 20 in the X and Y directions, making it contact the locking inclined block 51. When more than 2 / 3 of the contact surface is pressed together, the power battery pack assembly 50 and the base 23 are locked, keeping their position fixed, thus completing the locking and fixing work. When the locking mechanism unlocks, the locking pin 11 on the base 23 moves radially inwards along the inner cavity of the pin sleeve 20 in the X and Y directions under the pulling force of the power component 30, making it completely disengage from the locking inclined block 51 and retract into the baffle 21. The power battery pack assembly 50 is then disengaged and lifted out of the base 23 by the lifting equipment, completing the unlocking and realizing the battery swapping operation of the battery swapping vehicle.

[0057] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
