The position of the second threaded hole 24 corresponds to the position of the first through hole. The threaded connector 4 passes through the first threaded bore and is rotationally locked in the second threaded bore 24. The positions of the first through hole and the second threaded hole 24 can be selected according to requirements of different embodiments on the brake box and the lock shell. Various embodiments are provided.

As shown in fig. 1, 3 and 4, the first front wall 11 of the brake box 1 is provided with two first through holes 14, and the second side wall 22 of the lock housing 2 is correspondingly provided with two second threaded holes 24. The second threaded hole 24 extends parallel to the height of said second side wall 22 itself, i.e. the second threaded hole 24 extends in the second side wall 22. As shown in fig. 3, in a state where the lock case 2 is assembled in the brake housing 1, the second side wall 22 is substantially perpendicular to the first front wall 11, and the first through hole 14 faces an end surface of the second side wall 22. By designing the above-mentioned second threaded hole 24, the threaded connector 4 can be extended into the second side wall along the height direction of the second side wall, and the second threaded hole can have a longer thread so that the threaded connector forms a stable and reliable locking relationship.

Optionally, in other embodiments, the first through hole may also be opened on the first sidewall. The second threaded hole is formed in the second side wall. The extending direction of the second screw hole may be parallel to the height direction of the second sidewall. Wherein the second screw hole may be formed on a partial structure of the second sidewall extending in parallel with the axial direction of the first through hole. In such an embodiment, the second threaded hole needs to be formed at a corner of the sidewall structure of the two sections of the second sidewall bent to each other. The threaded connector penetrates into the brake box from the first through hole and is screwed into a second threaded hole which is positioned at the corner and extends horizontally along the second side wall. Alternatively, the second threaded hole may be formed in a portion of the structure of the second sidewall extending perpendicular to the axial direction of the first through hole. In this embodiment, the threaded connector passes through the first through hole and is screwed into the second threaded hole, and if the second threaded hole is a through-hole, the threaded connector may extend directly into the lock housing. Further, the thickness of the second side wall can be increased, or the thickness of the second side wall around the second threaded hole is increased, so that the thread length of the second threaded hole is increased, and the locking reliability is improved.

The threaded connector 4 is inserted into the second through hole 5 from the outside of the brake box 1, passes through the second through hole 5 of the brake box 1 communicated with the lock shell 2 and is rotationally locked on the nut 25.

This embodiment eliminates the need for the second threaded hole to be formed directly in the lock housing. The nut is adopted to provide the threaded connection part, the reliability of the thread is higher, and the situations of thread slipping, thread damage and the like are more difficult to occur. The threaded connection can form a firmer locking function, and the lock shell is firmly connected with the brake box 1.

Alternatively, as shown in fig. 1 to 4, the second through hole 5 is formed on the second sidewall 22 and the first sidewall. The second through hole 5 is located at a position where the first and second sidewalls 22 are attached to each other. In the embodiment shown in fig. 3, two second through holes 5 are formed in the first side wall, and the two second through holes 5 are located at symmetrical positions of two sections of the second side wall 22. Two second through holes 5 are correspondingly formed in the second side wall 22, the two second through holes 5 are located in an area where the second side wall 22 can be attached to the first side wall, and the two second through holes 5 in the second side wall 22 are also symmetrically distributed. This embodiment enables the side walls of the brake housing 1 and the lock housing 2 to be laterally limited. Further, by combining this embodiment with the above-described fixing manner of the first through hole 14 and the second screw hole 24, the fixing action can be more effectively achieved. The threaded connection piece 4 forms spacing fixed to the lock from two directions of first antetheca 11 and the first lateral wall of brake box 1, and the reliability is showing and is improving. Fig. 1 and 2 show in combination a solution for such a combined threaded connection 4.

The second through hole 5 can also be formed in the first front wall, and the corresponding lock case requires a second through hole 5 formed in the second side wall 22 parallel to its height direction, or a second through hole 5 formed in the second bottom wall for the threaded connection 4 to pass through.

The nut 25 is inserted into the fixing groove 26, the shape of the fixing groove 26 matches with the overall shape of the nut 25, and the nut 25 cannot move or rotate after being placed in the fixing groove 26. The structure complexity of fixing the nut in the lock shell is simplified on the one hand by the design mode, the structure of the lock shell can form a fixing groove only through simple change, and the corner connecting part of the second side wall and the second bottom wall can be utilized by the fixing groove, so that the nut is accurately fixed. On the other hand, the nut is also relatively simple to assemble, as long as the nut is inserted or snapped into the fixation groove. The relatively complex processing modes of integrally forming the nut inside the lock shell and the like are not needed.

Optionally, the nut 25 is a square nut 25, and the fixing groove 26 is also a rectangular groove. The square nut 25 and the rectangular fixing groove 26 can form good and stable positioning fit, the rectangular groove can effectively limit the rotation of the nut 25, and the nut is prevented from rotating, shaking and the like when being locked by the threaded connecting piece 4.

Alternatively, as shown in fig. 4, in the area of the lock case 2 around the lock pin hole 23, the thickness of the second side wall 22 is greater than the thickness of the other area of the second side wall 22. The locking pin 3 penetrates out of the locking pin hole 23 so that the locking piece can form locking to prevent wheels or handlebars of the shared bicycle from rotating, and accordingly locking of the bicycle is achieved. If the shared bicycle is subjected to vehicle stealing or external collision, the locking pin and the locking piece are likely to be subjected to destructive acting force, and then the locking pin can collide and rub with the locking pin hole. The present application increases the thickness of the second sidewall around the locking pin hole to improve the structural reliability of the second sidewall thereat. The design mode can improve the anti-theft performance of the brake lock to a certain extent and reduce the possibility of damage of the brake lock.

Alternatively, as shown in fig. 4, the area of the lock case 2 around the lock pin hole 23, the top of the second side wall 22 may be formed with a step structure 27. The step formation 27 increases the ability of the second side wall 22 to resist impact and to restrain deformation in this region. Step structure has formed more structures such as turning, closed angle, and it has produced more stress concentration points, and more stress concentration points mean that the external mechanical effort that receives can disperse each stress concentration point, and the holistic structural reliability of second lateral wall is showing and is improving around the lockpin hole. The step structure can also improve the height change characteristic of the second side wall in a step form, so that the second side wall has smoother height change integrally, and the design is also favorable for improving the structural reliability.

Alternatively, the second threaded hole 24 described herein may be formed on the stepped structure 27, as shown in fig. 4. This technical scheme utilizes the higher characteristics of structural reliability that step structure 27 goes out, with second screw hole 24 overall arrangement here, can wholly improve brake box 1 and lock shell 2's reliability of being connected. And the step structure 27 itself is higher in height, so that the upper second threaded hole 24 can provide a longer extension space to some extent.

Optionally, as shown in fig. 4, a transition rounded corner structure 28 is formed between the second side wall 22 and the second bottom wall 21 in the area around the locking pin hole 23. The transition rounded corner structure 28 can reduce the stress concentration at the joint of the second side wall 22 and the second bottom wall 21, and smoothly disperse the applied external force to the second bottom wall 21 and the second side wall 22. Transition fillet structure 28 can also improve the structural strength between second lateral wall 22 and the second diapire 21, and the transition fillet structure 28 that increases has increased the thickness of both junctions, and structural strength obtains promoting.

Several of the above alternative embodiments can be applied in combination in a set of solutions, as shown in fig. 4. These structural features combine to provide an integral reinforcement of the region of the second side wall 22 where the locking pin aperture 23 is located, so that this portion of the structure can withstand greater external impact forces.

Alternatively, the second threaded hole 24 is provided near the lock pin hole 23. The characteristic that the structural strength of the part around the lock pin hole 23 is higher can be utilized, and the connection reliability between the lock shell 2 and the brake box 1 is further improved in an integrated mode. As shown in fig. 4, in this embodiment, two second threaded holes 24 are located on both sides of the locking pin hole 23. The threaded connecting piece 4 is connected around the lock pin hole 23, and can also reinforce the lock pin hole 23 by itself, so that the lock pin hole 23 is protected from being collided by the lock pin 3.

Optionally, the brake lock may further comprise a strip shaped fixing element 6, as shown in fig. 1 to 3. The strip-shaped fixing member 6 spans the opening 13 and covers the outer surface of the second bottom wall 21, and two ends of the strip-shaped fixing member 6 are respectively fixed on two opposite portions of the first side wall. The bar-shaped fixing piece 6 is used for enabling the lock shell 2 to form a semi-encircling posture so as to further enhance the connection reliability of the lock shell 2 and the brake box 1 and prevent the lock shell 2 from falling off from the opening 13 of the brake box 1 under the accidental condition. The strip-shaped fixing member 6 can contact and press-fit with the outer surface of the second bottom wall 21.

Alternatively, the two ends of the strip-shaped fixing member 6 are fixed to the first side wall together by the above-mentioned screw fixing member. For example, as shown in fig. 2, the fixing positions of the two ends of the strip-shaped fixing member 6 are opposite to the second through hole 5, and the two ends of the strip-shaped fixing member 6 are fixed on the side walls through the threaded connection member 4. The fixing mode not only saves connecting points needing to be fixedly connected, reduces the number of parts, but also can integrally improve the assembly reliability of the brake lock.

Alternatively, the strip-shaped fixing member 6 is formed with a positioning hole 61, as shown in fig. 3, and the outer surface of the second bottom wall 21 is formed with a positioning protrusion 211, as shown in fig. 2. The positioning protrusion 211 is inserted into the positioning hole 61. This design achieves a relative positioning of the strip-shaped fastening element 6 with respect to the lock housing 2, while the strip-shaped fastening element 6 is itself fixedly connected to the first side wall of the brake housing 1. The structural design mode improves the overall assembly accuracy and structural reliability of the brake lock.
