Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present invention, the following description of the preferred embodiments of the present invention is provided in conjunction with specific examples, but it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.

The present invention will be further described with reference to the following examples and figures 1-18, but the invention is not limited thereto.

As shown in fig. 2, the shooting hole assembly comprises a core 1, a shell 2, a return mechanism 3 and an operating mechanism 4. Wherein, the shell 2 is internally provided with a spherical cavity 21, and two sides of the cavity 21 are symmetrically provided with round shooting holes 22 communicated with the outside; the core body 1 is arranged in a spherical shape and is matched with the cavity 21, the core body 1 is arranged in the cavity 21, and a shooting channel 11 which can be communicated with the two shooting holes 22 is arranged in the core body 1 along one direction of the spherical center of the core body 1 in a penetrating way; the operating mechanism 4 is connected with the core 1 and penetrates out of the shell 2, and the core 1 is driven to rotate relative to the shell 2 through the operating mechanism 4 under the action of external force, so that the shooting channel 11 is overlapped and staggered with the shooting hole 22, and the shooting hole 22 is opened and closed, as shown in fig. 1.

As shown in fig. 3, two circular cut surfaces 12 are cut on the outside of the core 1 in the other direction crossing the center of the core 1 and orthogonal to the firing channel 11, and the firing hole 22 is opened when the firing channel 11 of the core 1 is rotated to the area of the firing hole 22 of the cavity of the shell 2; when the section 12 of the core body 1 rotates to the area of the shooting hole 22 of the cavity 21, the shooting hole 22 is closed, and the section 12 of the core body 1 and the end plane of the shell 2 where the shooting hole 22 is located are kept on the same plane; this ensures that the core 1 does not project beyond the outer surface of the housing 2 in the closed state of the firing hole 22, and does not interfere with the movement of the wiper or the like in the closed state of the firing hole 22 when the firing hole assembly is arranged on the front windshield.

As shown in fig. 4 and 5, the housing 2 is the mounting base of the firing hole assembly, and the core 1, the return mechanism 3 and the operating mechanism 4 are all mounted in the housing 2, and the firing hole assembly is also mounted on different parts of the vehicle through the related structure of the housing 2. The outer shape of the housing 2 can be designed in different shapes as desired. In the scenario of the application case, the outer shell 2 is designed to be cylindrical, the cavity 21 is arranged in the middle of the cylinder for arranging the core 1 and other mechanisms, and the height of the cylinder is set to ensure that the shooting holes 22 at the two ends of the cavity 21 reserve the rotating space of the shooting channel 11. In order to put the core 1 and other mechanisms into the cavity 21 of the shell 2, the shell 2 is designed into an upper part and a lower part, and the upper shell 23 and the lower shell 24 are connected into a whole through bolts.

As shown in fig. 6-8, in order to limit the moving range of the core 1 rotating in the housing 2, a part of sphere is cut at the upper and lower ends of the core 1 to reserve a space as an installation platform, the two platforms are symmetrically provided with rotating shafts 13, and the rotating shafts 13 are sleeved with return mechanisms 3 for returning the core 1. The return mechanism 3 comprises two semicircular springs 31 which are spliced with each other, a circular ring 32 matched with the second groove 14 arranged on the rotating shaft is formed in the middle of the splicing position of the two semicircular springs 31, an opening 33 is formed in the outer ring of each semicircular spring 31 to ensure that the springs can be installed, and the springs cannot be separated when deformed; a third groove 26 is formed in the first groove 25 for accommodating two semicircular springs 31. The first groove side wall 27 limits the range of rotation of the spindle 13 of the core, indirectly determining the range of rotation of the firing channel 11. The first groove top 28 is also spherical and is matched with the top (also spherical) of the rotating shaft 13 of the core body 1 to ensure the stable rotation of the core body 1. When the core body 1 is rotated by an external force, the rotation shaft 13 presses the semicircular spring 31 to rotate to a desired angle. When the core body 1 loses the external force, the semicircular spring 31 elastically drives the rotating shaft 13 of the core body 1, so that the core body 1 returns to the initial position.

The return mechanism 3 formed by matching the two semicircular springs 31 has a simple structure and high reliability. Of course, other ways are also possible, for example, 3 tension springs may be provided, evenly distributed along the third groove 26, with one end connected to the rotation shaft 13 of the core 1 and one end connected to the first groove sidewall 27 of the housing 2, and may also serve a similar function.

As shown in fig. 9, the connecting structure 40 is sleeved on the rotating shaft 13 and located above the second groove 14, the edge of the connecting structure 40 contacts with the first groove sidewall 27 at the top of the housing 2 to limit the rotating range of the core 1, and indirectly limits the rotating range of the firing channel 11, and the rotating range of the firing channel 11 is a tapered region. The rotation range can be adjusted by adjusting the length of the firing channel 11, the diameter of the firing hole 22, the height of the cylinder of the housing 2 and the like to meet different requirements. In this application, the rotation range of the shooting hole 22 is a tapered region of-15 °.

As shown in fig. 10 to 14, the firing aperture 22 is switched between the open state and the closed state by the operating mechanism 4. The operating mechanism 4 includes a connecting structure 40 arranged on the rotating shaft and a first cable 41 with one end connected with the connecting structure 40 and the other end penetrating through the outer shell 2, a first spring 43 is sleeved on the first cable 41, the first spring 43 is arranged in a first mounting hole 48 of the outer shell 2, a first spring blocking piece 46 for limiting the first spring 43 to move outwards is arranged on the outer shell 2 outside the first mounting hole 48, and a spring limiting piece 45 for compressing the first spring 43 is fixedly arranged on the first cable 41. When the shooting hole 22 is in the open state, the spring stopper 45 follows the first cable 41 to approach the first spring stopper 46 and press the first spring 43.

In order to better realize the rotation and the reset of the core body 1, a second cable 42 is further arranged on the connecting structure 40, one end of the second cable 42 is connected with the connecting structure 40, the other end of the second cable penetrates through the outer shell 2, a second spring 44 is sleeved on the second cable 42, the second spring 44 is arranged in a second mounting hole 49 of the outer shell 2 in a built-in mode, and a second spring blocking piece 47 for limiting the second spring 44 to move outwards is arranged on the outer shell 2 outside the second mounting hole 49.

Further, the connecting structure 40 is a disk having an annular groove, and the ends of the first cable 41 and the second cable 42 are respectively snapped into the annular groove of the disk, and when one of the cables is pulled to rotate the core body 1, the other cable is wound in the annular groove.

The initial state of the firing channel 11 is a closed state, and if the core 1 is in an open state (i.e. the first spring 43 is in a compressed state) under the action of external force, when the external force disappears, the core 1 can rotate to the closed state under the action of the elastic force of the first spring 43. Therefore, the inhaul cable for driving the core body 1 from the closed state to the open state is provided with the spring limiting sheet 45, the shell 2 outside the mounting hole is provided with the first spring blocking sheet 46, when the shooting channel 11 of the core body 1 is in the open state, the first spring 43 is in the compressed state, and when the shooting channel 11 of the core body 1 rotates to the closed position, the first spring 43 is in the free state and is not stressed. The second spring 44 on the other side only acts as a guide to prevent the second cable 42 from bending and is basically in an unstressed state. In order to mount the cable and the spring of the operating mechanism 4, the upper part of the housing 2 is cut out from a plane passing through the center of the cable and spring mounting hole, and the cut-out upper cover 231 after the cable and the spring are mounted is fixed to the upper housing 23 by bolts, as shown in fig. 15.

In order to prevent rainwater and dust from entering the vehicle through the gap between the core body 1 and the cavity 21, a groove is arranged on the outer cavity 21 near the outer side of the plane parallel to the section of the shell 2, and an O-shaped sealing ring is arranged in the groove to seal the gap, as shown in FIG. 16.

As shown in fig. 17 and 18, when the shooting hole 22 is in a closed state, the cut surface 12 of the core 1 is kept on the same plane as the end of the shell 2. Therefore, when the firing hole assembly is mounted on the windshield, the firing hole assembly is in the same plane with the outer surface of the windshield in the closed state, and the operation of the wiper and the like is not affected. In the open state of the shooting hole 22, since the core 1 is only rotated by 90 °, substantially no additional space is occupied, and there is no problem that the glass is scratched when the cover is opened outward. The core 1 serves as both the firing hole 22 and the cap for the firing hole 22. The core 1 rotates in the spherical cavity of the shell 2, depends on the spherical surface of the core 1 to contact with the cavity 21, and meanwhile, the sections of the rotating shafts 13 at the upper end and the lower end of the core 1 are also spherical surfaces which can be tightly attached to the spherical surface of the top 28 of the upper first groove and the lower first groove of the shell 2, so that the core 1 rotates stably and smoothly, the operating force is small, and meanwhile, extra hole cover connecting parts and the like do not need to be arranged, so that the whole shooting hole assembly is small in number of parts and simple in structure.

The length of the firing channel 11 is greater than the distance between two firing holes 22 of the shell 2, and when the firing holes 22 are in an open state, the core 1 protrudes out of a part of the cross section of the shell 2, so as to ensure that the barrel can freely rotate within the rotation range of the firing channel 11 without colliding with the shell 2 when the firing channel 11 is in use, as shown in fig. 9 and 11.

In the application case, when the shooting hole assembly is installed on the front windshield glass, the shooting hole assembly and the bulletproof glass are bonded in a gluing mode because the bulletproof glass cannot be provided with bolt fixing holes and the thickness of the glass is thick. If the shooting hole assembly is installed at other parts of the vehicle body, a flange edge can be arranged on the shell 2 of the shooting hole assembly and connected through bolts.

It will be apparent to those skilled in the art from this disclosure that the present invention may be readily made and used with a firing hole assembly, and that the positive results set forth herein may be achieved.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
