[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The object of the present invention is to provide a data recorder to solve the problems existing in the prior art and to achieve a better fixing effect between a recording unit in the data recorder and a data recorder housing.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The present invention provides a data recorder, such as Figures 1 to 5As shown, it includes: a recording unit, a spherical storage chamber 3 and a shell, the shell includes an upper cover 1 and a lower shell 6, the recording unit is connected to the spherical storage chamber 3, the spherical storage chamber 3 is arranged in the shell, and a support seat 4 is fixedly provided on the lower shell 6, and the support seat 4 is provided with a first groove whose inner wall can fit with the outer wall of the spherical storage chamber 3, and the first groove is used to fit and support the lower part of the spherical storage chamber 3, and a second groove is provided on the upper cover 1. The upper cover 1 is fixedly connected to the lower shell 6 so that the second groove is pressed against the upper part of the spherical storage chamber 3, and the connection line of the recording unit can pass through the spherical storage chamber 3 and the first groove in sequence to connect with the recorder circuit board 5 arranged in the lower shell 6. By limiting the spherical storage chamber 3 in the space formed by the first groove of the support seat 4 and the second groove of the upper cover body 1, the inner walls of the first groove and the second groove can fit the inner walls of the spherical storage chamber 3, and then the upper cover body 1 is fixedly connected to the support seat 4. This design can independently limit the spherical storage chamber 3 in the space formed by the first groove of the support seat 4 and the second groove of the upper cover body 1. The spherical storage chamber 3 is not easy to be displaced, and will not move and collide with other components in the data recorder, making the connection between the recording unit in the data recorder and the lower shell 6 of the data recorder more stable and reliable, thereby making the recording unit in the data recorder and the lower shell 6 of the data recorder fixed better, and in the data recorder When the recorder is subjected to external impact or strong vibration, the spherical storage chamber 3 will not be easily displaced because it has been firmly confined in the space with the same shape as the spherical storage chamber 3 formed by the first groove of the support base 4 and the second groove of the upper cover body 1. This effectively avoids the possibility of accidental disconnection between the internal circuit of the spherical storage chamber 3 and the recorder circuit board 5. At the same time, it can also effectively prevent the spherical storage chamber 3 from hitting other components in the lower shell 6 due to shaking, thereby protecting other components from damage, enhancing the overall impact resistance and stability of the data recorder, and ensuring that the equipment can maintain efficient and stable operation under various harsh conditions.

[0028] When in use, the spherical storage chamber 3 is placed into the upper cover body 1, and then the upper cover body 1 is covered on the groove of the support seat 4. The spherical storage chamber 3 is limited by the second groove of the upper cover body 1 and the first groove of the support seat 4, and then the recorder circuit board 5 is fixedly connected to the lower shell 6. The circuit of the spherical storage chamber 3 can pass through the through hole opened on the first groove and be connected to the recorder circuit board 5. Finally, the upper cover body 1, the support seat 4 and the lower shell 6 are fixedly connected, which can make the recording unit in the data recorder and the lower shell 6 of the data recorder better fixed, and the spherical storage chamber 3 and the recorder circuit board 5 are separated by the support seat 4, which can effectively prevent the spherical storage chamber 3 from being displaced and hitting the recorder circuit board 5 in the lower shell 6 of the data recorder when the data recorder is hit, causing damage to the recorder circuit board 5.

[0029] In another embodiment of the present invention, a connecting plate 2 is fixedly connected to the notch of the second groove of the upper cover 1. The upper cover 1 and the support base 4 are fixedly connected by the connecting plate 2, which can make the connecting surface of the upper cover 1 and the support base 4 fit more closely, thereby improving the connection effect between the upper cover 1 and the support base 4.

[0030] In another implementation of this embodiment, the upper cover body 1, the support base 4 and the lower shell 6 are fixedly connected by bolts; the bolt connection has a good fixing effect and can facilitate the disassembly and assembly of the upper cover body 1, the support base 4 and the lower shell 6, facilitate the inspection and replacement of parts of the data recorder, make it more convenient to use, and improve maintenance efficiency.

[0031] It should be noted that, in the data recorder provided by the present invention, the connection method of the upper cover 1, the support base 4 and the lower shell 6 is not limited to the structure in the above-mentioned embodiment, and riveting, welding, snap connection and the like can also be used to ensure that the upper cover 1, the support base 4 and the lower shell 6 are firmly connected.

[0032] In another embodiment of this embodiment, after the spherical storage chamber 3 is placed in the upper cover 1, the gap between the spherical storage chamber 3 and the upper cover 1 is sealed and bonded by filling with glue, and the gap at the connection between the recorder circuit board 5 and the lower shell 6 is also sealed and bonded by filling with glue. This can effectively prevent moisture and dust from entering the gap between the spherical storage chamber 3 and the upper cover 1 or the gap at the connection between the recorder circuit board 5 and the lower shell 6, increase the bonding strength between the components, and reduce the risk of loosening or damage caused by vibration or impact. When in use, first place the spherical storage chamber 3 in the upper cover 1, fill the gap between the spherical storage chamber 3 and the upper cover 1 with sealant, and after the spherical storage chamber 3 and the upper cover 1 are firmly fixed, cover the upper cover 1 on the first groove of the support seat 4, and limit the spherical storage chamber 3 by the upper cover 1 and the first groove. Preferably, the glue used for the injection seal is potting silicone.

[0033] It should be noted that the glue used for injection sealing of the data recorder provided by the present invention is not limited to the materials in the above-mentioned embodiment, and epoxy resin glue, polyurethane sealant, etc. can also be used to seal the gap between the spherical storage chamber 3 and the upper cover body 1, as well as the gap at the connection between the recorder circuit board 5 and the lower shell 6.

[0034] In another embodiment of this invention, after the spherical storage chamber 3 is placed in the upper cover 1, the gap between the spherical storage chamber 3 and the upper cover 1 is sealed by filling it with glue, and the gap at the connection between the recorder circuit board 5 and the lower housing 6 is also sealed by filling it with glue. This can improve the fixing effect between the spherical storage chamber 3 and the inner wall of the groove, and better fix the recording unit in the data recorder to the data recorder housing 6.

[0035] In another embodiment of this invention, after the upper cover 1, support base 4, and lower housing 6 are bolted together, the gaps between the upper cover 1, support base 4, and lower housing 6 are sealed by injecting glue. This improves the fixing effect between the upper cover 1, support base 4, and lower housing 6, and further improves the fixing effect between the recording unit in the data recorder and the data recorder housing 6.

[0036] In another embodiment of this invention, the upper cover body 1 includes an outer cover and an inner cover. The outer cover is sleeved over the inner cover, and the outer cover and the inner cover are fixedly connected. The inner cover has a second groove that can fit with the outer wall of the spherical storage chamber 3. The inner wall of the second groove fits with the spherical storage chamber 3, which can better limit the position of the spherical storage chamber 3. In addition, the double-layer upper cover structure of the outer cover and the inner cover provides a buffering effect for the inner cover, reducing the impact of external shocks on the spherical storage chamber 3, thereby enhancing the overall impact resistance and stability of the data recorder.

[0037] In another embodiment of this invention, the space between the outer cover and the inner cover is filled with a first cushioning material. When the data recorder is subjected to external impact, the first cushioning material between the outer cover and the inner cover can provide a buffer, reducing the impact on the spherical storage chamber 3 and improving the fixing effect between the recording unit in the data recorder and the data recorder housing 6. Preferably, the first cushioning material is potting silicone.

[0038] It should be noted that, in the data recorder provided by the present invention, the material of the first buffer material is not limited to the materials in the above embodiment, and silicone sealant, polyurethane sealant, etc., which can provide a buffering material, can also be used.

[0039] In another embodiment of this embodiment, the spherical storage chamber 3 includes multiple shells arranged sequentially from the inside out, with equal gaps between adjacent shells. The gaps between adjacent shells are filled with a second buffer material, and the recording unit is fixedly mounted within the inner cavity of the innermost shell of the spherical storage chamber 3. The multi-layer shell structure provides a multiple protective barrier for the recording unit. Even if the outer layer is damaged, the inner layer can still remain intact, ensuring the safety of the recording unit. Moreover, because the gaps between adjacent shells are equal and filled with the second buffer material, when an external impact force is applied, the second buffer material can effectively absorb and disperse the impact force, reducing the impact on the internal recording unit. Preferably, the shell is made of titanium alloy, and the second buffer material is potting silicone.

[0040] It should be noted that the material of the shell of the data recorder provided by the present invention is not limited to the materials in the above embodiments, and can also be made of metal materials such as aluminum, stainless steel, or non-metallic materials such as nylon, PLA or red wax.

[0041] It should be noted that the material of the second buffer material of the data recorder provided by the present invention is not limited to the materials in the above embodiment, and silicone sealant, polyurethane sealant, etc. can also be used, which can provide a buffering material.

[0042] In another embodiment of this embodiment, the filling density of the second buffer material in the gaps between adjacent shell layers is the same, and the filling density of the second buffer material in each gap is uniform, so that the spherical storage chamber 3 is subjected to uniform force, thereby increasing the strength of the spherical storage chamber 3.

[0043] In another embodiment of this embodiment, the filling density of the second buffer material in the gap between adjacent shell layers gradually increases from the outer gap to the inner gap, and the filler in each layer of gap is evenly filled. The gap closer to the outside is sparser in density, and the gap closer to the inside is denser in density. The sparser filler layout in the outer layer is more prone to dynamic instability under impact load, resulting in large elastic-plastic deformation, thereby absorbing most of the impact energy. The denser filler layout in the inner layer has higher strength and rigidity, reducing the risk of large deformation in the adjacent safety space.

[0044] In another embodiment of this embodiment, a first jack 7 is formed on the lower housing 6, to which a plug 8 is fixedly connected. The recorder circuit board 5 is signal-connected to the plug 8. The recorder circuit board 5 and the plug 8 can be signal-connected via a wire. The provision of the plug 8 facilitates the connection of external devices to the recorder circuit board 5, making it more convenient to use.

[0045] In another embodiment of this embodiment, two first jacks 7 are provided, and two plugs 8 are fixedly connected to the two first jacks 7. Providing two plugs 8 provides two independent pathways. Even if one plug or connection fails, the other can still ensure normal operation of the device, improving the reliability and stability of the system and facilitating future functional expansion. If new functions or modules need to be added, the second plug can be directly used without making large-scale changes to the existing structure.

[0046] In another embodiment of this invention, the two plugs 8 serve as a data connector and a network connector, respectively. The network connector is used to output data, while the data connector is used to store data. This clear functional division of the two plugs 8 reduces interference between different functions and improves system stability and efficiency. Because each plug 8 has a single, clear function, system administrators and users can more easily understand its purpose during use, reducing the possibility of misoperation. Furthermore, troubleshooting allows for faster problem location.

[0047] In another embodiment of this embodiment, a grounding hole is further provided on the lower housing 6 for connecting to a ground post. Connecting the lower housing 6 to the ground post via the grounding hole effectively prevents the risk of electric shock due to static electricity accumulation or leakage in the housing, thereby ensuring the personal safety of the operator and providing greater safety.

[0048] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
