Technical Field

[0001] The present application relates to the automotive field, and in particular to a hard disk enclosure, a hard disk assembly, and an automobile. Background Art

[0002] With the continuous growth of data information in the automotive application field, especially the realization of the storage function of large amounts of data in automobiles, such as video recorders, vehicle driving data recorders and other devices, it is inevitable to use hard disks with storage functions. Hard disks have become one of the necessary configurations in these vehicle-mounted storage products.

[0003] Because hard drives require power to store data, currently available in-vehicle hard drive enclosures are typically powered by external devices. If the vehicle experiences a power outage while in motion, or if the vehicle experiences a collision and the entire vehicle loses power, the hard drive stops functioning and becomes unable to store data. Furthermore, a power outage can damage the hard drive, significantly impacting the integrity and reliability of data recording. Summary of the Invention

[0004] Based on this, it is necessary to provide a hard disk box, a hard disk assembly and a car, which can ensure that the hard disk can still work normally and store data when the power of the entire vehicle is cut off.

[0005] Specifically, the present application first provides a hard disk box, including: a shell, including a first side wall and a first bottom wall, the first side wall and the first bottom wall are arranged to form a accommodating groove; a bracket, arranged in the accommodating groove, including a second bottom wall and a second side wall arranged at intervals, the second side wall and the second bottom wall are arranged to form a accommodating space for accommodating the hard disk, the bracket also includes an interface board, the interface board is provided with a conductive end and is used to communicate with the hard disk; and a power generation component, arranged between the shell and the bracket, including a power storage module and a plurality of power generation units electrically connected to the power storage module, each of the power generation units including a deformable vibrating member and a piezoelectric sheet arranged in the hollow vibrating member, each of the piezoelectric sheet is electrically connected to the conductive end, and both ends of each of the vibrating members are respectively fixed on the shell and the bracket.

[0006] In the above-mentioned hard disk case, when the vehicle vibrates, the bracket will move relative to the shell. At this time, due to the change in the distance between the bracket and the shell, the vibrating member will be squeezed by the bracket and the shell and deformed. When the vibrating member is deformed, the piezoelectric piece will be subjected to stress changes, polarization will occur and electrical energy will be generated. The electrical energy generated by the piezoelectric piece can be stored in the power storage module. The hard disk case can collect the energy generated by its own vibration and utilize this energy to store the energy in the form of electricity, thereby saving energy. In addition, when the vehicle loses power, the electrical energy in the power storage module can continue to power the hard disk, ensuring that the hard disk can continue to work normally and store data, avoiding damage to the hard disk, while also ensuring the integrity and reliability of data recording.

[0007] In one embodiment, the piezoelectric sheets of the plurality of power generation units are arranged in different directions, and the directions of the piezoelectric sheets are perpendicular to the axis of the plane of the piezoelectric sheet.

[0008] This arrangement allows different piezoelectric sheets to be subjected to stress changes in different directions, thereby utilizing the energy generated by vibrations in different directions.

[0013] In one embodiment, each of the second side walls is provided with two mounting portions and three mounting positions, and the two mounting portions are provided at both ends of the side wall body.

[0014] This arrangement ensures that the energy generated by the bracket vibrating relative to the housing along the Z-axis at each position can be utilized.

[0015] In one embodiment, the vibrating member includes a deformation portion and fixed portions provided at both ends of the deformation portion, a cavity is provided in the deformation portion, the piezoelectric sheet is fixed in the cavity, and the fixed portions are respectively fixed to the bracket and the shell.

[0016] With such a configuration, the cavity can enhance the deformation capacity of the deformation portion to amplify the vibration of the bracket relative to the housing; at the same time, it can ensure that the deformation portion can drive the piezoelectric piece to deform synchronously when it deforms.

[0017] In one embodiment, a groove is formed on the inner wall of the deformation portion, and the end of the piezoelectric sheet is inserted into the groove.

[0018] With such an arrangement, the groove can ensure the reliability of the connection between the piezoelectric sheet and the deformable portion, and further ensure that the deformable portion can drive the piezoelectric sheet to deform synchronously when it deforms.

[0019] In one embodiment, the deformation portion has an annular cavity.

[0020] With such an arrangement, the annular cavity has a stronger deformation capability, thereby being able to further amplify the vibration of the bracket relative to the housing.

[0021] In one embodiment, the power generation unit further includes a fixing block arranged on the fixing portion; the two fixing blocks of the power generation unit are respectively fixed on the mounting portion and the first bottom wall; or the two fixing blocks of the power generation unit are respectively fixed on the mounting position and the first side wall.

[0022] With such arrangement, the fixing block can ensure the stability and reliability of the connection between the vibrating element, the bracket and the housing.

[0023] In one embodiment, the vibrating member is fixed to the fixing block by hot pressing.

[0024] With such arrangement, the hot pressing forming processing method is simple, the cost is low, and the stability and reliability of the connection between the vibrating member and the fixing block can be ensured.

[0025] In one embodiment, the first side wall includes a front side wall and a rear side wall, the front side wall is provided with a handle, the rear side wall is provided with an adapter plate, and the adapter plate is electrically connected to the interface board for communication.

[0026] With this arrangement, the handle can facilitate users to plug and unplug the hard disk box; the adapter board can also communicate and connect with other modules inside the vehicle, so that the interface board can communicate and connect with other modules inside the vehicle through the adapter board.

[0027] In one embodiment, the hard disk box also includes a processing module arranged on the interface board, each of the power generation units is electrically connected to a corresponding processing module, and the processing module includes a rectifier circuit, a filter circuit and a voltage stabilizing circuit connected in series in sequence; the power storage module is arranged on the interface board and is electrically connected to the power generation unit through the processing module, and is used to store the electrical energy of the power generation unit.

[0050] With the continuous growth of data information in the automotive application field, especially the realization of the storage function of large amounts of data in automobiles, such as video recorders, vehicle driving data recorders and other devices, it is inevitable to use hard disks with storage functions. Hard disks have become one of the necessary configurations in these vehicle-mounted storage products.

[0051] Because hard drives require power for storage, current in-vehicle hard drive enclosures are typically powered by external devices. If the vehicle experiences an unexpected power outage while in motion, or if the vehicle crashes, resulting in a complete power outage, the hard drive ceases operation and becomes unable to store data. Furthermore, unexpected power outages can damage the hard drive, significantly impacting the integrity and reliability of recorded data. With the continuous improvement of vehicle safety, the requirements for the integrity and reliability of recorded driving data are becoming increasingly stringent. Therefore, it is crucial to configure the hard drive to store recorder and driving data even in the event of a complete power outage.

[0052] It is understandable that since the vehicle will always vibrate during driving and the energy generated by this vibration is large, it is also of great significance to collect the energy generated by this vibration and power on-board storage devices such as hard drives.

[0053] In order to solve the above problems, Figures 1 to 11 As shown, the present invention first provides a hard disk box, which can ensure that the hard disk can work normally and store data when the whole vehicle is powered off, avoiding damage to the hard disk, and at the same time ensuring the integrity and reliability of data records.

[0054] like Figure 1 、 Figure 2 and Figure 6 As shown, specifically, the hard disk case includes a shell 10, a bracket 20 and a power generation component 30, wherein: the shell 10 includes a first side wall 11 and a first bottom wall 12, and the first side wall 11 and the first bottom wall 12 are arranged to form a receiving groove 13; the bracket 20 is arranged in the receiving groove 13, and includes a second bottom wall 21 and a second side wall 22 arranged at intervals, and the second side wall 22 and the second bottom wall 21 are arranged to form a receiving space 23 for receiving the hard disk 40, and the bracket 20 also includes an interface board 24, on which a conductive end 241 is provided and is used to communicate with the hard disk 40; the power generation component 30 is arranged between the shell 10 and the bracket 20, and includes a power storage module and a plurality of power generation units 31 electrically connected to the power storage module, each power generation unit 31 includes a deformable vibration member 311 and a piezoelectric piece 312 arranged in the hollow vibration member 311, each piezoelectric piece 312 is electrically connected to the conductive end 241, and both ends of each vibration member 311 are respectively fixed on the shell 10 and the bracket 20.

[0055] The conductive end 241 may be a conductive solder joint or a conductive interface, etc., as long as it can be electrically connected to the hard disk 40 through conductive elements such as wires, and no specific limitation is made here.

[0056] As mentioned above, existing vehicle-mounted hard disk boxes are generally powered by external devices. When the entire vehicle loses power, the hard disk stops working and cannot store data. It may also cause damage to the hard disk, greatly affecting the integrity and reliability of data recording. In the hard disk box provided by the present invention, the hard disk 40 is fixedly arranged in the accommodating space 23 of the bracket 20 by screws, snaps or adhesives, and is communicatively connected to the conductive end 241. When the vehicle vibrates, the bracket 20 moves relative to the shell 10. At this time, due to the change in the distance between the bracket 20 and the shell 10, the vibrating member 311 will be squeezed by the bracket 20 and the shell 10 and deformed. When the vibrating member 311 is deformed, the piezoelectric piece 312 is subjected to stress changes, polarization occurs, and electrical energy is generated. The electrical energy generated by the piezoelectric piece 312 can be stored in the battery module. When an abnormal power outage occurs while the vehicle is driving, or the vehicle collides and the entire vehicle loses power, the electrical energy in the battery module can continue to power the hard disk 40, ensuring that the hard disk 40 can continue to work normally and store data, avoiding damage to the hard disk 40, and at the same time ensuring the integrity and reliability of data records.

[0057] In addition, the hard disk box can collect the energy generated by its own vibration and utilize the energy to store the energy in the form of electricity to power the hard disk 40 and other vehicle-mounted storage devices in an emergency, saving energy and also playing an effective prevention and response function.

[0058] It is understood that the power storage module is not connected to other power supply modules in the vehicle, and the power storage module will supply power to the hard disk 40 only when the vehicle is powered off.

[0059] When the power is off, the hard disk 40 is powered by the power supply module inside the vehicle, and the storage module does not power the hard disk 405, so as to ensure that there is enough electric energy stored in the storage module when the vehicle is powered off.

[0060] like Figure 2 and Figure 7 As shown, the housing 10 further includes a top wall 16 disposed opposite to the first bottom wall 12. The top wall 16 can be opened or closed so as to facilitate installation or removal of the bracket 20 and the hard disk 40 when the top wall 16 is opened. The first side wall 11 includes a front side wall 111, a rear side wall 112, and two oppositely disposed left and right side walls 113.

[0061] Front wall 111, rear side wall 112, and two left and right side walls 113 form a rectangular frame. A handle 14 is provided on front side wall 111 to facilitate inserting and removing the hard drive enclosure. An adapter plate 15 is provided on rear side wall 112. Adapter plate 15 is electrically connected to interface board 24 and can also communicate with other modules within the vehicle, such as the power supply module. This allows interface board 24 to communicate with other modules within the vehicle, such as the power supply module, through adapter plate 15.

[0062] like Figure 6 As shown, in the embodiment shown in the figure, the bracket 20 includes a third side wall 25 and two second side walls 22 arranged on both sides of the third side wall 25. The interface plate 24 is fixed by screws, buckles or adhesives.

[0063] In another embodiment, the bracket 20 may also include two third side walls 25 arranged opposite to each other, and the two third side walls 25 and the two second side walls 22 are surrounded to form a rectangular frame, and the interface plate 24 is arranged on the third side wall corresponding to the rear side wall 112.

[0064] Of course, in other embodiments, the bracket 20 may also include only two second side walls 22, and the two second side walls 22 are oppositely arranged on both sides of the interface plate 24.

[0065] like Figures 2 to 3 As shown in Figure 2, the vehicle will vibrate in multiple directions during driving, such as Figure 1 and Figure 3 The X-axis direction, Y-axis direction, Z-axis direction, XY direction, XZ direction, YZ direction, and other arbitrary directions of the spatial rectangular coordinate system shown. Therefore, the piezoelectric sheets 312 of the multiple power generation units 31 are arranged in different directions, and the vibrating member 311 can deform in multiple directions, so that different piezoelectric sheets 312 can be subjected to stress changes in different directions, thereby utilizing the energy generated by vibrations in different directions. Among them, the direction of the piezoelectric sheet 312 is the axial direction perpendicular to the plane of the piezoelectric sheet 312, that is, the a-axis direction as shown in 9.

[0066] like Figure 2 and Figure 4As shown, since the vibrations occurring along the Z-axis are most significant during the driving process of the vehicle, in one embodiment, the second side wall 22 includes a side wall body 221 and a mounting portion 222 extending from the upper edge of the side wall body 221 and away from the accommodating space 23. Some power generation units 31 are disposed between the mounting portion 222 and the first bottom wall 12, and the piezoelectric sheets 312 of these power generation units 31 face the Z-axis. When the vehicle generates vibrations in the Z-axis direction during driving, due to the existence of inertia, the bracket 20 will generate an acceleration along the Z-axis relative to the housing 10. As shown in FIG. Figure 10 As shown, according to Newton's second law, the mounting portion 222 and the first bottom wall 12 exert an alternating tensile and compressive force F0 on the vibrating member 311, causing the vibrating member 311 to undergo both tensile and compressive deformation. According to the force conduction decomposition, the tensile force F0 generates a tensile force F1 at the piezoelectric element 312. The piezoelectric element 312 experiences a stress change, polarizing, and generating electrical energy.

[0067] The sidewall body 221 is provided with a mounting portion 2211, and the remaining power generation units 31 are disposed between the sidewall body 221 and the left and right sidewalls 113. The piezoelectric plates 312 of these power generation units 31 face the Y-axis direction. When the vehicle generates vibrations in the Y-axis direction while driving, the sidewall body 221 and the left and right sidewalls 113 exert an alternating tensile and compressive force F0 on the vibrating element 311, causing the piezoelectric plates 312 to generate electrical energy. Simultaneously, when the vehicle generates vibrations in the X-axis direction while driving, the bracket 20 and the housing 10 simultaneously exert a lateral shear force on the vibrating element 311 disposed between the mounting portion 222 and the first bottom wall 12, and on the vibrating element 311 disposed between the sidewall body 221 and the left and right sidewalls 113, causing the vibrating element 311 to deform and the piezoelectric plates 312 to generate electrical energy.

[0068] In another embodiment, without affecting the electrical connection between the interface board 24 and the adapter board 15, a mounting position 2211 can be provided on the third side wall 25. Some power generation units 31 are disposed between the third side wall 25 and the front side wall 111 or between the third side wall 25 and the rear side wall 112, with the piezoelectric plates 312 of these power generation units 31 oriented in the X-axis direction. When the vehicle vibrates in the X-axis direction while driving, the third side wall 25, the front side wall 111, and the rear side wall 112 exert an alternating tensile and compressive force F0 on the vibrating element 311, causing the piezoelectric plates 312 to generate electrical energy.

[0069] Of course, in other embodiments, corresponding mounting members oriented in other directions, such as the XY, XZ, YZ, or any other direction, may be provided on the bracket 20 and the housing 10. The mounting member orientation is perpendicular to the axis of the mounting member plane. A portion of the power generation unit 31 is disposed between two corresponding mounting members. When the two mounting members generate an alternating tensile and compressive force F0 on the vibrating member 311, the piezoelectric sheet 312 generates electrical energy.

[0070] like Figures 4 and 5 As shown, in the illustrated embodiment, the bracket 20 includes two second side walls 22, each of which is provided with at least m mounting portions 222 and at least n mounting positions 2211, each mounting portion 222 and each mounting position 2211 corresponding to a power generation unit 31. A plurality of conductive terminals 241 are provided on both sides of the interface plate 24, corresponding to the two second side walls 22. Each conductive terminal 241 includes (m+n) positive terminals and one negative terminal. The positive terminal on each piezoelectric sheet 312 is electrically connected to one of the positive terminals of the conductive terminals 241, and the negative terminal on the piezoelectric sheet 312 is electrically connected to the negative terminal of the conductive terminals 241. m ≥ 2, n ≥ 1, and m and n are both integers. Since the vibration of a vehicle along the Z-axis is most significant during driving, at least two mounting portions 222 are required on each second side wall 22 to ensure that the energy generated by the vibration of the bracket 20 relative to the housing 10 along the Z-axis can be fully utilized. At the same time, at least one mounting position 2211 is provided on each second side wall 22 to ensure that the energy generated by the vibration of the bracket 20 relative to the housing 10 along the Y-axis direction can also be utilized.

[0071] like Figures 8 and 9 As shown, in the illustrated embodiment, the positive and negative terminals on the piezoelectric sheet 312 are positive conductive pads 312a and negative conductive pads 312b. Of course, in other embodiments, the positive and negative terminals on the piezoelectric sheet 312 can also be conductive interfaces or other structures, as long as they can be electrically connected to the conductive terminal 241 through conductive elements such as wires, and there is no specific limitation here.

[0072] Specifically, each second side wall 22 is provided with two mounting portions 222 and three mounting positions 2211, and the two mounting portions 222 are provided at both ends of the side wall body 221. Five power generation units 31 are connected to each second side wall 22, and five positive terminals and one negative terminal are provided on both sides of the interface board 24. Among them, the piezoelectric sheet 312 of the power generation unit 31 connected to the mounting portion 222 faces the Z-axis direction, and the piezoelectric sheet 312 of the power generation unit 31 connected to the mounting position 2211 faces the Y-axis direction. The power generation units 31 with two piezoelectric sheets 312 facing the Z-axis direction are arranged at both ends of the power generation units 31 with three piezoelectric sheets 312 facing the Y-axis direction, so as to ensure that the energy generated by the vibration of the bracket 20 along the Z-axis direction relative to the shell 10 at each position can be utilized.

[0073] Of course, in other embodiments, each second side wall 22 may also be provided with three mounting portions 222 and three mounting positions 2211, three mounting portions 222 and four mounting positions 2211, four mounting portions 222 and three mounting positions 2211, or even more mounting portions 222 and mounting positions 2211. The specific number and arrangement are not limited here.

[0074] like Figures 8 and 9 As shown, the vibrating member 311 includes a deformable portion 3111 and fixed portions 3112 located at both ends of the deformable portion 3111. The deformable portion 3111 defines a cavity 3111a, and the piezoelectric plate 312 is fixedly disposed within the cavity 3111a. The fixed portions 3112 are fixed to the bracket 20 and the housing 10, respectively. The cavity 3111a enhances the deformable capacity of the deformable portion 3111, thereby amplifying the vibration of the bracket 20 relative to the housing 10. Furthermore, as the deformable portion 3111 deforms, the shape and size of the cavity 3111a also change, thereby ensuring that the deformable portion 3111 can drive the piezoelectric plate 312 to deform synchronously.

[0075] The vibration member 311 may be configured as a deformable and elastic element such as a rubber member or a silicone member.

[0076] like Figure 9 As shown, in the illustrated embodiment, a groove 3111b is provided on the inner wall of the deformable portion 3111, and the end of the piezoelectric piece 312 is inserted into the groove 3111b. The cooperation between the piezoelectric piece 312 and the groove 3111b can ensure the reliability of the connection between the piezoelectric piece 312 and the deformable portion 3111, and prevent the piezoelectric piece 312 from being separated from the deformable portion 3111 when the deformable portion 3111 is deformed, thereby further ensuring that the deformable portion 3111 can drive the piezoelectric piece 312 to deform synchronously when it is deformed. Of course, in other embodiments, the end of the piezoelectric piece 312 can also be connected to the inner wall of the deformable portion 3111 by screws, snaps, or gluing.

[0077] like Figures 8 and 9 As shown, in the illustrated embodiment, the deformable portion 3111 has an annular cavity, which has a strong deformability, thereby further amplifying the vibration of the bracket 20 relative to the housing 10. In other embodiments, the deformable portion 3111 may also have a cavity of other regular or irregular shapes, such as a rectangular cavity or a triangular cavity.

[0078] like Figures 8 and 9 As shown, since the vibration member 311 is a deformable and elastic element, in order to ensure the stability and reliability of the connection between the vibration member 311 and the bracket 20 and the shell 10, the power generation unit 31 also includes a fixing block 313 arranged on the fixing portion 3112; the two fixing blocks 313 of the power generation unit 31 are respectively fixed on the mounting portion 222 and the first bottom wall 12; or the two fixing blocks 313 of the power generation unit 31 are respectively fixed on the mounting position 2211 and the first side wall 11.

[0079] The fixing block 313 can be fixedly connected to the bracket 20 and the housing 10 by fasteners such as screws or bolts. In this case, each mounting portion 222 and each mounting position 2211 is provided with a through hole, and a corresponding position on the first side wall 11 is also provided with a through hole. The fasteners such as screws or bolts are passed through the through holes and fixedly connected to the fixing block 313. Of course, the fixing block 313 can also be fixedly connected to the bracket 20 and the housing 10 by other means such as snap fasteners or gluing, as long as the stability and reliability of the connection between the fixing block 313, the bracket 20 and the housing 10 can be guaranteed. No specific limitation is imposed here.

[0080] In one embodiment, the vibrating member 311 and the fixing block 313 are fixed by hot pressing. Hot pressing is a simple and cost-effective method, and can ensure the stability and reliability of the connection between the vibrating member 311 and the fixing block 313. Of course, in other embodiments, the vibrating member 311 and the fixing block 313 can also be fixed by other means such as gluing, screws, or clips, and no specific limitation is given here.

[0081] like Figure 11 As shown, the hard disk enclosure also includes a processing module mounted on the interface board 24. Each power generation unit 31 is electrically connected to a corresponding processing module. The processing module includes a rectifier circuit, a filter circuit, and a voltage stabilization circuit connected in series. A power storage module is mounted on the interface board 24 and electrically connected to the power generation unit 31 via the processing module, storing the electrical energy generated by the power generation unit 31. The electrical energy generated by the power generation unit 31 is processed sequentially by the rectifier circuit, the filter circuit, and the voltage stabilization circuit before being stored in the power storage module via the control system.

[0082] The rectifier circuit converts AC power into DC power and is typically composed of a transformer, a main rectifier circuit, and a filter. The filter circuit, typically composed of reactive components, removes ripple from the rectifier output voltage. The voltage regulator circuit maintains a relatively constant output voltage despite fluctuations in the input grid voltage or changes in the load.

[0083] Adapter board 15 is equipped with an acceleration sensor and a voltage detection sensor. When the acceleration sensor detects that the acceleration value per unit time reaches a set threshold, the vehicle is determined to have crashed. Alternatively, when the voltage detection sensor detects that the external power supply voltage falls below a set threshold, the vehicle or equipment is determined to have experienced an abnormal power outage. At this point, the battery module's discharge function is activated, continuously supplying power to hard disk 40. This ensures the integrity of data recorded before and after the vehicle's power outage, preventing damage to hard disk 40 or data loss caused by the abnormal power outage.

[0084] like Figure 1 and Figure 6 As shown, the present invention also provides a hard disk assembly comprising a hard disk 40 and the aforementioned hard disk enclosure. The hard disk 40 is disposed within the accommodating space 23 and is communicatively connected to the interface board 24. The power storage module is electrically connected to the power generation assembly 30 and the hard disk 40. During normal vehicle operation, the power generation assembly 30 converts vibrations into electrical energy and stores the energy in the power storage module. When the vehicle is powered off, the power storage module continues to supply power to the hard disk 40.

[0085] The present invention also provides a car comprising the hard disk assembly. The hard disk assembly is modular in design and can be applied to cars of different equipment and models, with high versatility and interchangeability.

[0086] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
