[0001] The utility model relates to a missile-borne recorder technical field, concretely relates to a recorder buffer structure and missile-borne recorder. BACKGROUND

[0002] When carrying out artillery shell or missile test, various data of the missile need to be recorded so as to facilitate subsequent analysis and improvement. As a key information storage device, the data recorder needs to continuously record various core parameters in the operation process, and its working environment is often accompanied by violent vibration, impact load and complex stress. Once the recorder is damaged due to external impact or load impact, the key data will be directly lost, which will further lead to test failure. The existing design is to fill the shell of the recorder with buffer material, but in actual use, after using the filling material, the information storage device can be protected to a certain extent, but when the impact force is too large, the shell is broken, and the irregular shell fragments are easy to hurt the storage device, resulting in damage to the storage device.

[0003] In view of the above, there is an urgent need for a recorder buffer structure and missile-borne recorder to solve or at least partially solve the problems existing in the prior art. INVENTION CONTENTS

[0028] In order to facilitate understanding of the utility model, the utility model will be described more comprehensively below, and the preferred embodiment of the utility model is given. However, the utility model can be realized in many different forms, and is not limited to the embodiments described in the present text. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0030] Embodiment 1:

[0031] Referring to Figures 1-4 , the embodiment provides a recording instrument buffer structure, which comprises a shell 1, an accommodating cavity 11 for installing a storage device 5 is arranged in the shell 1, a release slot 12 is arranged on the shell 1 and extends along the circumference of the shell 1;It also comprises a support assembly 2 for installing the storage device 5, the support assembly 2 is arranged in the accommodating cavity 11, and the support assembly 2 is fixedly connected with the shell 1.

[0032] It should be noted that the missile-borne recording instrument is directly installed on the missile which needs to be tested, when the missile hits the target, the missile will produce violent impact with the target, and in the existing test, it is found that when the missile hits the target, the recording instrument shell 1 installed on the missile is prone to rupture, and the ruptured shell 1 is prone to stab the internal storage device 5.

[0033] Through research and continuous experimentation, it was discovered that cutting a release groove 12 into the recorder's housing 1 creates a relatively weaker section at this location due to the removal of material. This makes the release groove 12 the first point of failure upon missile impact; the housing 1 will shear and crack at this point. This shearing and cracking at the release groove 12 absorbs the impact energy, reducing damage to the internal storage device 5. Furthermore, it should be noted that when the housing 1 breaks, it will crack along the release groove 12, rather than fracturing into fragments elsewhere, thus preventing damage to the internal storage device 5.

[0034] Furthermore, the release groove 12 is arranged around the front end of the housing 1.

[0035] It is understood that by setting the release groove 12 at the front end of the housing 1, when the housing 1 is impacted, the front end of the housing 1 is the first to be impacted, causing the release groove 12 of the housing 1 to absorb the impact energy and be damaged, thereby protecting the storage device 5 inside the housing 1.

[0036] Specifically, in this embodiment, the release groove 12 is spiral-shaped and arranged around the housing 1. The housing 1 is cylindrical, and the spiral release groove 12 is arranged around the outer periphery of the housing 1, with the release groove 12 spatially offset from the internal storage device 5. When the housing 1 is impacted, it is sheared and broken along the spiral groove, causing the damaged portion of the housing 1 to move obliquely along the spiral. Because the release groove 12 and the storage device 5 are spatially offset, the damaged portion of the housing 1 will not collide with the internal storage device 5 during the movement, thus protecting the internal storage device 5 from damage.

[0037] It should be noted that in some other embodiments of this utility model, the release groove 12 can also be arranged in a circular shape and the release groove 12 surrounds the housing 1.

[0038] Specifically, in this embodiment, the release groove 12 extends circumferentially along the outer surface of the housing 1, making it relatively easy to process. Of course, in some other embodiments of this application, the release groove 12 may also extend circumferentially along the inner surface of the housing 1.

[0039] Furthermore, in this embodiment, the cross-sectional shape of the release groove 12 is arranged as a semi-circle.

[0040] It should be noted that in some other embodiments, the cross-section of the release groove 12 can also be arranged as a trapezoid, triangle, or rectangle. When arranged as a semi-circular cross-section, the impact energy absorbed is the greatest.

[0041] Further, an end cover 3 is detachably connected to the front end of the shell 1, and the end of the shell 1 away from the end cover 3 is arranged in an open manner.

[0042] It can be known that, by arranging the detachable end cover 3 at the front end of the shell 1, the end cover 3 is conveniently detached, the shell 1 on one side of the end cover 3 is opened, and the inside of the shell 1 is conveniently arranged to install the support assembly 2 and the storage device 5. The end cover 3 is detachably connected by screws. The middle part of the end cover 3 is arranged in a recessed manner towards the inside of the shell 1, and the end of the end cover 3 towards the outside is used to install connection accessories such as a data recording port, a high-speed output port, and a video recording port.

[0043] Further, a filling layer 4 is arranged in the shell 1, and the filling layer 4 is arranged to fill the containing cavity 11.

[0044] It can be known that, by filling the containing cavity 11 with the filling layer 4 and wrapping the storage device 5 with the filling layer 4, the filling layer 4 is supported by foaming material such as soft material like foam. When impacted, the filling material deforms and absorbs energy to form a buffer for the storage device 5, preventing the storage device 5 from being damaged by excessive impact. Further improve the protection of the storage device 5.

[0045] Further, a reinforcing rib 13 is arranged inside the shell 1, the reinforcing rib 13 is arranged around the inner wall of the shell 1, and the reinforcing rib 13 is arranged at the end of the shell 1 close to the storage device 5.

[0046] It can be known that, by arranging the reinforcing rib 13 inside the shell 1, the end of the shell 1 close to the storage device 5 is reinforced by the reinforcing rib 13, so that the end of the shell 1 provided with the release slot 12 is damaged, and the end of the shell 1 close to the storage device 5 is prevented from being damaged, thereby improving the protection of the storage device 5.

[0047] Further, the support assembly 2 comprises a support rod 21 and a support frame 22, the support rod 21 and the support frame 22 are arranged in an axial interval along the shell 1, and the support rod 21 is arranged at the front end of the support frame 22.

[0048] The support rod 21 is detachably connected in the shell 1 by screws, the support frame 22 is detachably connected in the shell 1 by screws, the support rod 21 and the support frame 22 are located in a unified plane, and the storage device 5 is detachably connected on the support rod 21 and the support frame 22 by screws or bolts. By arranging the support rod 21 and the support frame 22, the storage device 5 is conveniently installed and fixed.
