Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 shows a locked state of the locking mechanism, and fig. 2 shows an unlocked state of the locking mechanism, and as shown in fig. 1 and 2, the vehicle body side member and the battery pack frame side member cooperate to achieve a quick locking and unlocking operation.
Fig. 3 to 7 show the detailed construction of the present lock mechanism, and with reference to fig. 5 to 7, the present lock mechanism mainly includes a first lock body 1, a lock assembly 2, and a second lock body 3.
The first lock body 1 is fixed on the vehicle body through threaded connection. The first lock body 1 is a cylindrical lock head, a lock groove is formed in the first lock body, and a plurality of rolling bodies 25 which are radially arranged can be matched with the lock groove, so that the first lock body is positioned and locked on the second lock body 3.
The second lock body 3 is fixed on the battery frame by welding or other methods, and the locking assembly 2 is installed in the second lock body.
The locking assembly 2 mainly comprises a fixed ring 21, a movable ring 22, a spring 23, a locking seat 24, a rolling body 25 and a rolling body retainer 26.
The inner side of the fixed ring 21 has a toothed groove, and the inner and outer sides of the moving ring 22 have toothed grooves. The locking socket 24 has a toothed groove on the outside. The matching relationship is as follows: the locking and unlocking operation passage 31 is formed between the fixing ring 21 and the locking socket 24. When the device is locked, the movable ring 22 is jacked up corresponding to the locking and unlocking fork, the spring 23 is extruded, the movable ring moves along the axial direction of the locking seat and is separated from the fixed ring, and then the locking seat 24 can rotate in a controlled manner.
The rolling elements 25 are located in radial slots of a rolling element cage 26. The inner circumferential wall surface of the locking socket 24 is divided into a locking portion 241 and an unlocking portion 242 along the axial direction thereof, wherein the locking portion 241 is in contact with the rolling elements to force the rolling elements to radially protrude from the central bore of the rolling element cage 26. The unlocking 242 allows the rolling bodies 25 to be retracted from the central bore into the radial slot holes.
Preferably, the radial groove hole 261 is a constricted hole for preventing the rolling elements from falling off.
The locking socket 24 and the rolling element cage 26 are screwed together, the locking socket 24 being axially displaceable relative to the rolling element cage 26, and both the locking part and the unlocking part being in controlled contact with the rolling elements. When the rolling elements protrude radially out of the central bore of the rolling element cage 26, the rolling elements engage in the locking grooves of the first lock body, so that locking is achieved. When the rolling elements 25 are retracted from the central bore, unlocking of the first lock is achieved.
After the external lock fork is withdrawn, the spring rebounds back to the movable ring, so that the fixed ring, the movable ring and the locking seat are mutually fixed to prevent looseness.
And in the locking process, the moving ring 22 is jacked up by corresponding locking and unlocking tooth shapes, simultaneously, the unlocking teeth are meshed with the teeth on the locking seat 24, the locking seat 24 is circumferentially fixed relatively, the spring 23 is extruded simultaneously, the moving ring 22 is separated from the fixed ring 21, at the moment, the locking seat 24 rotates reversely, the rolling seat 24 moves downwards to leave a groove space for the rolling body 25, then, the rolling body 25 is squeezed out by the first lock body 1 and inserted into a rolling body retainer 26 in the locking assembly, and then locking is carried out.
The unlocking teeth drive the rotary locking seat 24, the locking seat 24 and the rolling body retainer 26 are matched through threads and move oppositely, the rolling body 25 is extruded, the rolling body 25 is clamped in the locking groove of the first lock body 1, the first lock body, the locking seat 24 and the rolling body retainer 26 extrude the rolling body 25 towards different directions, and the first lock body 1 is clamped and tightened as the rotary depth is deeper, so that the fastening of the battery pack frame and the vehicle body is realized; after the unlocking fork teeth are withdrawn, the spring 23 rebounds back to the movable ring 22 to re-enable the fixed ring 21, the movable ring 22 and the locking seat 24 to be mutually meshed and fixed to prevent loosening, and the locking process of the locking device is finished.
An unlocking process: when unlocking, the unlocking fork teeth jack up the moving ring 22, then the locking seat 24 is rotated and unlocked, at the moment, the locking seat 24 and the retainer 26 which are connected through threads move backwards, the rolling body 25 is not extruded any more, the first lock body 1 is pulled away to extrude the rolling body 25 into the radial slotted hole 261 of the retainer 26, at the moment, the first lock body 1 can be separated from the locking assembly 2 and the second lock body 3, and therefore the battery pack and the vehicle body are separated.
In the present locking mechanism, a locking seat 24 is designed to switch the positions of the rolling elements in the rolling element cage. The operation manner of the lock socket is not limited to the screwing (the lock socket relatively moves and the lock portion and the unlock portion on the inner peripheral wall surface are aligned in the axial direction thereof) described above. The locking seat may be operated in other alternative ways, such as only rotating operation, for example, three rolling bodies rotate the locking seat at intervals of 60 ° to realize the switching between locking and unlocking, and correspondingly, the locking part and the unlocking part on the inner peripheral wall surface of the locking seat are arranged at a height along the circumferential direction.
The locking mechanism is provided with a rolling body, namely a steel ball, to lock the cylindrical lock head, wherein the rolling body can be replaced by a positioning pin.
The locking mechanism achieves the requirement of rapid locking and unlocking through the locking groove of the rolling body, and the structure of the locking mechanism has universality. The user can select the scheme according to the layout and the project requirement.
The invention avoids the defects of the prior art, the battery pack lock body and the vehicle lock body are fixed together through extrusion force in three directions, the spherical rolling bodies clamp the lock body, the abrasion generated can be digested through rotating the extrusion force, the equipment cost can be reduced, the equipment maintenance difficulty can be reduced, and the equipment utilization rate can be increased.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
