Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the embodiment.

Example 1

As shown in fig. 1 to 2, a lock structure mainly comprises a support part 1 and a lock tongue 2. Specifically, the bearing part is C-shaped, and with reference to fig. 1 as a direction, a bearing space 11 is formed in a side surface of the bearing part 1 close to the latch 2, and the bearing space 11 may be a groove structure penetrating through the thickness direction of the bearing part 1, or may be a groove structure penetrating through the thickness direction of the bearing part 1 as long as it can allow the side shaft of the electric vehicle battery to slide therethrough and provide a sufficient supporting force to the side shaft, and in use, the bearing space 11 is used for a side shaft or the like of the electric vehicle battery to be locked.

After the side shaft of the battery enters the bearing space 11, the opening of the groove structure of the bearing space 11 needs to be blocked by the bolt 2, so that the side shaft of the battery is prevented from coming out. The bolt 2 is configured as follows:

1) the bolt 2 is provided with a stopping part 21 for stopping at the opening of the groove structure of the bearing space 11. The end of the stopping part 21 far away from the hinge mounting position of the bolt 2 forms an acute angle 26 with an inclined bottom 27, and one side of the acute angle 26 for blocking is a vertical surface, a roughly vertical surface, an inclined surface far away from the blocking direction, and the like, so as to avoid that the stopping part 21 is lifted by the pressing separation of the side shaft to cause unlocking.

2) The bottom 27 of the acute angle 26 is an inclined plane raised away from one side of the bearing space 11, and through the structural arrangement, the lifting of the bolt 2 at a smaller angle is realized as far as possible, and the space of the side shaft sliding channel 3 is vacated to a larger extent by the abutting part 21, so that the requirement on the lifting angle of the bolt 2 can be effectively reduced. On the premise that a huge electric automobile battery occupies a large space of an electric automobile chassis, any space which is matched with the locking and unlocking mechanism is occupied very tightly, and the space is saved very rarely.

3) An extension 24 is formed on the latch bolt 2, and the extension 24 is farther away from the elastic return element 23 relative to the hinge mounting position of the latch bolt 2. The extending part 24 extends from the stopping part 21 to the upper part of the bearing part 1 and bends downwards to form a stopping end around the bearing part 1. During action, the unlocking mechanism is abutted to the abutting end, and the abutting end is lifted to drive the bolt 2 to move so as to release the locking of the abutting part 21 from the bearing space 11. Because the contact end extends downwards for a certain distance, the lifting distance of the unlocking mechanism does not need to be too long, and the purpose of saving occupied space in the chassis as much as possible is also achieved, and the quantity of the batteries of the electric automobile is increased.

As a mounting base of the bolt 2, a lock base 22 hinged in the middle of the bolt is provided. The lock base 22 has the following structural features in order to achieve the corresponding functions:

1) an avoiding space 25 is arranged at the upper right part of the lock base 22, and an elastic resetting piece 23 for fixedly mounting a spring is arranged in the avoiding space 25. The elastic reset piece 23 is located between the lock base 22 and the lock tongue 2, and cooperates with a hinge point between the middle part of the lock tongue 2 and the lock base 22 to realize the rotation locking and unlocking of the lock tongue 2 through a lever principle. Further, in order to avoid the spring etc. elasticity piece 23 that resets to collapse and take off, set up the recess in 2 downside tip positions on the spring bolt to extend the projection of guide in the recess middle part, and the external diameter of projection is less than the internal diameter of recess, so that elasticity piece 23 that resets can block between projection and recess. Of course, if the fixation is sufficiently firm, the elastic restoring member 23 may be fixed only by using a groove or a convex column structure. The corresponding position of the lock base 22 is also provided with the elastic reset piece 23 fixing structure according to the above scheme.

2) The lock base 22 and the support portion 1 are provided independently of each other. Compared with the prior mode that the base is integrally formed, the mode that the side shaft accommodating space is formed on the left part and the bolt hinge space is formed on the right part respectively is one of the most important improvements of the technical scheme, and the problem that the base is modified to be integrally operated is directly solved. By means of the structural interruption of the base, the function of isolating the heavy load of the side shaft from the light load hinged with the lock tongue is involved, so that materials are saved, modification operation is simplified, the operation and maintenance cost of equipment is reduced, and the service life of the equipment is prolonged. For example, in the conventional structure formed integrally, since the stopper portion 21 of the tongue 2 needs to vertically penetrate the tongue 2 and be inserted into the opening of the receiving space 11 to close the opening, a vertical hole needs to be formed in the tongue 2. However, in actual use, the environment under the automobile chassis is severe, dust and stone particles are extremely numerous, and almost inevitably invade and block in the vertical hole, so that the lock tongue 2 is usually blocked in the vertical hole, and the replacement efficiency of the automobile battery is seriously influenced. The structure is broken, so that the existence of the easy-to-clamp area is fundamentally avoided, and the practical problem is solved.

Furthermore, in order to guide the bolt and reduce the requirement on the structural form of the bolt 2, an avoiding groove 12 with a certain depth can be reserved on the right end surface of the bearing part 1. The abutting part 21 is clamped into the avoiding groove 12 when the abutting part 21 blocks the bearing space 11, so that the side direction dislocation of the bolt 2 can be avoided to a certain degree. Accordingly, in the process of releasing the closing of the receiving space 11, the stopper portion 21 is lifted by the guide function of the escape groove 12.

The edge of the stop portion 21 is burred in the event of a long-term heavy impact on the side shaft, and the burred structure hinders the rotation of the stop portion 21 in the escape groove 12, and even causes seizure. In order to avoid this, the service life of the tongue 2 is extended, and in the present embodiment, in the case where the avoiding groove 12 is provided, the thickness of the acute angle position is set to be appropriately smaller than the thickness of the stopping portion away from the acute angle position. When the burr of the stopping portion 21 is generated, since a larger edge gap is generated between the avoiding groove 12 and the stopping portion 21, the burr is less likely to be expanded to a position where the avoiding groove 21 interferes, thereby alleviating the occurrence of the jamming phenomenon.

Between the lock base 22 and the support part 1, a passage 3 for the passage of the locking structure is formed, and the passage 3 is located on the side far from the stop part 21. The side shaft of the battery of the electric vehicle enters the position of the stopping part 21 through the channel 3, and when the unlocking mechanism lifts the bolt 2, the side shaft enters the bearing space 11. It should be noted that, in some embodiments, the bottom portion 27 is provided with a structure for guiding the side shaft so that the side shaft can easily lift the stopper portion 21, which is different from the present embodiment.

To sum up, through anticlockwise, clockwise drive spring bolt 2 rotates, can drive to hold off portion 21 and switch in shutoff bearing space 11 and the state that breaks away from shutoff bearing space 11, realize the locking to being locked structure with take off the locking.

Example 2

As shown in fig. 3-4, on the basis that the basic technical solution of embodiment 1 remains the same, the present embodiment is different in that:

through the optimization design of the structure of the bolt 2, the size of the bolt 2 on the left end face for plugging can be shrunk as much as possible, and the interference between the bolt 2 and the bearing part 1 in the rotating process is avoided. Therefore, an avoiding groove 12 does not need to be formed on the bearing part 2, and the width of the stopping part 21 of the bolt 2 can be increased due to no limitation of the avoiding groove 12, so that the stopping effect on the side shaft is improved; on the other hand, the processing procedures of the bearing part 1 are reduced, and the cost can be obviously saved in batch production; the problem of blocking stones in the avoiding groove 12 which possibly exists is solved in three aspects.
