Description

Technical Field

[0001] The present invention belongs to the technical field of automobiles, and more specifically, relates to a structure of an in-vehicle pull-out hard disk box. Background Art

[0002] In-vehicle video monitoring devices generally have a built-in hard disk or SD card for storing monitoring videos. At present, most hard disk boxes in the market are fixed together with a damping mechanism. When it is necessary to replace the hard disk, one solution is to disassemble the machine to replace the hard disk; another solution is to pull out the entire damping mechanism from the host and then disassemble and replace it, and the disassembly is complex and cumbersome.

[0003] In order to make the disassembly of the hard disk box more convenient, some hard disk boxes are made into pull-out hard disk boxes. However, when the pull-out hard disk box is snap-fixed on the hard disk seat, it is often difficult to press the buckle for pulling due to space limitations, resulting in difficult pulling of the hard disk box. Summary of the Invention

[0004] The purpose of the embodiment of the present invention is to provide a structure of an in-vehicle pull-out hard disk box to solve the technical problem in the prior art that the hard disk box is difficult to pull out due to space limitations.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: providing a structure of an in-vehicle pull-out hard disk box, including a fixed seat and a hard disk box. The hard disk box is slidably connected to the fixed seat, and the fixed seat has a first clamping portion for clamping and fixing the hard disk box. The hard disk box includes a box body, a first cantilever portion cantilever-connected to the box body, and a second cantilever portion cantilever-connected to the box body. The first cantilever portion has a first guiding surface, the second cantilever portion has a second guiding surface for the first guiding surface to abut against, and the second cantilever portion is also provided with a second clamping portion for snap-connecting with the first clamping portion. When the first cantilever portion is pressed and deformed, the first guiding surface presses the second guiding surface, causing the second cantilever portion to deform, and the pressing direction of the first cantilever portion and the deformation direction of the second cantilever portion are arranged at an angle.

[0006] Optionally, the sliding direction of the hard disk box is the first direction, the thickness direction of the hard disk box is the second direction, the first direction and the second direction are perpendicular to each other, the direction perpendicular to both the first direction and the second direction is the third direction, the pressing direction of the first cantilever portion is the third direction, and the deformation direction of the second cantilever portion is the second direction.

[0007] In the above solution, the first direction is the X direction, the second direction is the Z direction, and the third direction is the Y direction. Among them, the pressing direction of the first cantilever portion is the Y direction, and the deformation direction of the second cantilever portion is the Z direction. The pressing direction of the first cantilever portion and the deformation direction of the second cantilever portion are not the same and are perpendicular to each other. When extracting the hard disk box, it is possible to press in a direction to separate the first engaging portion and the second engaging portion engaged in the Z direction, making it more convenient for the user to take out the hard disk box.

[0008] Optionally, the first guiding surface and the second guiding surface are parallel to each other and are arranged at an acute angle with the third direction.

[0009] Optionally, the angle between the first guiding surface and the third direction is 30° to 60°.

[0010] Optionally, the first cantilever portion includes a connecting wall and a bending wall. One side of the connecting wall is connected to the box body, and the other side of the connecting wall is connected to the bending wall. The inside of the bending wall has an inclined plate, and the first guiding surface is located on the inclined plate.

[0011] Among them, the surface of the first cantilever portion has patterns, racks, etc., which can enhance the static friction between the user's finger and the first cantilever portion and prevent the finger from sliding when pressing. The specific shapes and distributions of the patterns and racks are not limited at this time, as long as the surface roughness of the first cantilever portion can be increased.

[0012] Optionally, the number of the first cantilever portions is two, and the second cantilever portion is located between the two first cantilever portions. Specifically, each first cantilever portion has a first guiding surface, and second guiding surfaces are arranged on both opposite sides of the second cantilever portion. The two first guiding surfaces and the corresponding second guiding surfaces are in guiding cooperation, which can deform the second cantilever portion. The two first cantilever portions act together, enabling the second cantilever portion to receive a greater pressure and making it easier for the second cantilever portion to deform.

[0013] Optionally, the outer shell of the box body includes an upper shell and a lower shell fixedly connected to the upper shell. The second cantilever portion is integrally formed with the upper shell, and the first cantilever portion is integrally formed with the lower shell.

[0014] Optionally, one side of the box body is provided with a first abutting portion, and the other side of the box body is provided with a second abutting portion. Both the first abutting portion and the second abutting portion are used for abutting against the inner wall of the fixed seat, and at least one of the first abutting portion and the second abutting portion is cantilever-connected to the box body.

[0015] Optionally, a limiting spring buckle for limiting the hard disk box is provided at one end of the fixed seat away from the first clamping portion, a positioning tongue is provided at one end of the fixed seat close to the first clamping portion, two positioning ribs are provided on the box body, and the positioning tongue is inserted between the two positioning ribs.

[0016] Optionally, the outer shell of the hard disk box is a plastic shell. The plastic shell will not cause a short circuit with the PCB of the hard disk body inside the hard disk box, and the plastic shell is light in weight and relatively portable, solving the problem of the heavy hard disk box.

[0017] The beneficial effects of the in-vehicle pull-out hard disk box structure provided by the present invention are as follows: Compared with the prior art, in the in-vehicle pull-out hard disk box structure of the present invention, the hard disk box is slidably connected to the fixed seat, the box body of the hard disk box is connected with a first cantilever portion and a second cantilever portion, the first cantilever portion has a first guiding surface, the second cantilever portion has a second guiding surface, and the second clamping portion on the second cantilever portion is clamped with the first clamping portion on the fixed seat. Press the first cantilever portion to press the first guiding surface against the second guiding surface, so that the second cantilever portion is deformed, and the hard disk box can be pulled out. The pressing direction of the first cantilever portion is different from the deformation direction of the second cantilever portion, so that when pulling out the hard disk box, it is not necessary to directly press the second cantilever portion, and the first cantilever portion can be pressed to pull out the hard disk box. In this way, when the user presses to open the buckle on the hard disk box, there is no need to be restricted by the position and pressing direction of the second cantilever portion, making it more convenient to pull out the hard disk box.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0032] The structure of the in-vehicle pull-out hard disk box provided by the embodiments of the present invention will now be described.

[0033] Please refer to Figures 1 to 3 , the structure of the in-vehicle pull-out hard disk box includes a fixed seat 1 and a hard disk box 2.

[0034] The fixed seat 1 is fixedly arranged and can be fixed inside the in-vehicle monitoring device. The hard disk box 2 is slidably connected to the fixed seat 1, and the hard disk box 2 can be pulled out relative to the fixed seat 1 so that the hard disk box 2 can be independently taken out from the in-vehicle monitoring device. The fixed seat 1 has a first clamping portion 11. When the hard disk box 2 is located inside the fixed seat 1, the fixed seat 1 is clamped and fixed inside the fixed seat 1 through the first clamping portion 11.

[0035] The hard disk case 2 includes a case body 23, a first cantilever portion 21 and a second cantilever portion 22. The first cantilever portion 21 and the second cantilever portion 22 are both cantilever - connected to the case body 23, and the first cantilever portion 21 and the second cantilever portion 22 can deform relative to the case body 23. A second clamping portion 27 is provided on the second cantilever portion 22, and the second clamping portion 27 is used to be clamped with the first clamping portion 11 on the fixed seat 1. When the hard disk case 2 is located in the fixed seat 1 and the first clamping portion 11 and the second clamping portion 27 are clamped, the hard disk case 2 is fixed in the fixed seat 1. The first cantilever portion 21 has a first guiding surface 2131, and the second cantilever portion 22 has a second guiding surface 221. When pressing the first cantilever portion 21, the first cantilever portion 21 deforms, and the first guiding surface 2131 on the first cantilever portion 21 abuts against the second guiding surface 221 on the second cantilever portion 22, causing the second cantilever portion 22 to deform. The deformation of the second cantilever portion 22 causes the second clamping portion 27 to disengage from the first clamping portion 11, so that the hard disk case 2 can be pulled out. Since this in - vehicle pull - out hard disk case structure is located in an in - vehicle monitoring device, it may be relatively difficult to press the second cantilever portion 22 of the hard disk case 2 due to space limitations. The pressing direction of the first cantilever portion 21 and the deformation direction of the second cantilever portion 22 are arranged at an angle. In this way, by pressing the first cantilever portion 21 in the M direction, the first guiding surface 2131 presses against the second guiding surface 221, so that the second cantilever portion 22 deforms in the N direction. The user does not need to press in the N direction to pull out the hard disk case 2 and can pull out the hard disk case 2 by pressing in the M direction. Therefore, in this embodiment, both the pressing position and the pressing direction for the user to press and open the hard disk case 2 can be adjusted through the first cantilever portion 21. In the case of a relatively compact space, it still does not affect the pulling - out and opening of the hard disk case 2.

[0036] In the in - vehicle pull - out hard disk case structure in the above - mentioned embodiment, the hard disk case 2 is slidably connected to the fixed seat 1. A first cantilever portion 21 and a second cantilever portion 22 are connected to the case body 23 of the hard disk case 2. The first cantilever portion 21 has a first guiding surface 2131, the second cantilever portion 22 has a second guiding surface 221, and the second clamping portion 27 on the second cantilever portion 22 is clamped with the first clamping portion 11 on the fixed seat 1. Press the first cantilever portion 21 to make the first guiding surface 2131 press against the second guiding surface 221, so that the second cantilever portion 22 deforms, and the hard disk case 2 can be pulled out. The pressing direction of the first cantilever portion 21 and the deformation direction of the second cantilever portion 22 are different, so that when pulling out the hard disk case 2, it is not necessary to directly press the second cantilever portion 22, and the first cantilever portion 21 can be pressed to pull out the hard disk case 2. In this way, when the user presses the buckle on the hard disk case 2 to open it, there is no need to be restricted by the position and pressing direction of the second cantilever portion 22, making it more convenient to pull out the hard disk case 2.

[0037] In one embodiment of the present invention, please refer to Figure 5 and Figure 6, the sliding direction of the hard disk case 2 is the first direction, the thickness direction of the hard disk case 2 is the second direction, and the first direction and the second direction are perpendicular to each other. The direction perpendicular to both the first direction and the second direction is the third direction. Among them, the length direction of the hard disk case 2 is the first direction, and the width direction of the hard disk case 2 is the third direction. The first direction is the X direction, the second direction is the Z direction, and the third direction is the Y direction. Among them, the pressing direction of the first cantilever portion 21 is the Y direction, and the deformation direction of the second cantilever portion 22 is the Z direction. The pressing direction of the first cantilever portion 21 and the deformation direction of the second cantilever portion 22 are not the same and are perpendicularly arranged. When extracting the hard disk case 2, it can be pressed in the Y direction to disengage the first engaging portion 11 and the second engaging portion 27 engaged in the Z direction, which is more convenient for the user to take out the hard disk case 2.

[0038] In other embodiments, the pressing direction of the first cantilever portion 21 is the Z direction, and the deformation direction of the second cantilever portion 22 is the Y direction.

[0039] Optionally, the first guiding surface 2131 and the second guiding surface 221 are parallel to each other. To ensure that the first cantilever portion 21 can press and deform the second cantilever portion 22, the first guiding surface 2131 and the second guiding surface 221 can be in contact. As long as the first cantilever portion 21 is pressed, the first guiding surface 2131 and the second guiding surface 221 will immediately press against each other to deform the second cantilever portion 22 to ensure the pressing effectiveness of the first cantilever portion 21. Both the first guiding surface 2131 and the second guiding surface 221 are arranged at an acute angle with the third direction (Y direction). When the first guiding surface 2131 and the second guiding surface 221 are in contact, the force in the Y direction (the force pressing the first cantilever portion 21) can be converted into the force in the Z direction (the force deforming the second cantilever portion 22). Specifically, when pressing the first cantilever portion 21 in the Y direction, the first guiding surface 2131 generates a pressure on the second guiding surface 221. This pressure can be decomposed into component forces in the Y direction and the Z direction. The component force in the Y direction abuts against the pressing force, and the component force in the Z direction can deform the second cantilever portion 22.

[0040] Among them, the included angle between the first guiding surface 2131 and the third direction (Y direction) is 30° to 60°. When this included angle is too small or too large, it is difficult to deform the second cantilever portion 22. Therefore, the included angle between the first guiding surface 2131 and the third direction is set to 30° to 60°, such as 30°, 45°, 50°, 55°, 60°, etc.

[0041] In other embodiments, the pressing direction of the first cantilever portion 21 and the deformation direction of the second cantilever portion 22 are arranged at an acute angle, as long as the pressing direction when the user opens the hard disk case 2 can be changed through the first cantilever portion 21.

[0042] In one embodiment of the present invention, please refer to Figure 4, the first cantilever portion 21 includes a connecting wall 211 and a bending wall 212. One side of the connecting wall 211 is connected to the box body 23, and the other side of the connecting wall 211 is connected to the bending wall 212. An inclined plate 213 is formed inside the bending portion of the bending wall 212. At least two side walls of the inclined plate 213 are connected to the inner wall of the bending wall 212, so as to enhance the strength of the bending wall 212. The first guiding surface 2131 is located on the inclined plate 213. The function of the bending wall 212 is to facilitate the formation of the inclined plate 213 and ensure the overall strength of the first cantilever portion 21.

[0043] Wherein, the surface of the first cantilever portion 21 has patterns, racks, etc., which can enhance the static friction between the user's finger and the first cantilever portion 21 and prevent sliding when the finger presses. The specific shapes and distributions of the patterns and racks are not limited at this time, as long as the surface roughness of the first cantilever portion 21 can be increased.

[0044] In one embodiment of the present invention, please refer to Figure 2 , the number of the first cantilever portions 21 is two, and the second cantilever portion 22 is located between the two first cantilever portions 21. Specifically, each first cantilever portion 21 has a first guiding surface 2131, and second guiding surfaces 221 are provided on opposite sides of the second cantilever portion 22. The two first guiding surfaces 2131 are in guiding cooperation with the corresponding second guiding surfaces 221, so that the second cantilever portion 22 can be deformed. The two first cantilever portions 21 act together, so that the pressure received by the second cantilever portion 22 is greater and the second cantilever portion 22 is more easily deformed.

[0045] In one embodiment of the present invention, the outer shell of the hard disk box 2 is a plastic shell. The plastic shell will not cause a short circuit with the PCB of the hard disk body 26 inside the hard disk box 2, and the weight of the plastic shell is relatively light, which is more portable and solves the problem of the heaviness of the hard disk box 2. In addition, since the outer shell of the hard disk box 2 is a plastic shell, it is also convenient to process irregular structures such as the first cantilever portion 21 and the second cantilever portion 22 on the outer shell of the hard disk box 2, and it is more convenient to realize the snap connection between the hard disk box 2 and the fixing seat 1. Specifically, the hard disk box 2 can be made by injection molding.

[0046] In one embodiment of the present invention, the first clamping portion 11 is a clamping hole, and the second clamping portion 27 is a clamping buckle. The second clamping portion 27 is provided on the second cantilever portion 22. The second cantilever portion 22 can be integrally injection molded with the box body 23. It is more convenient to process the second clamping portion 27 as a clamping buckle. The first clamping portion 11 is provided on the fixing seat 1. In order to ensure the strength of the fixing seat 1, the fixing seat 1 is usually a sheet metal part. Therefore, it is more convenient to design the first clamping portion 11 as a clamping hole. In other embodiments, the first clamping portion 11 can be a clamping buckle, and the second clamping portion 27 can be a clamping hole or a clamping groove.

[0047] In one embodiment, please refer toFigure 1 At the connection between the fixed seat 1 and the interior of the vehicle-mounted monitoring device, a vibration damping mechanism 12 can be provided to reduce the impact of vibration on the hard disk box 2. Additionally, by arranging the vibration damping mechanism 12 on the fixed seat 1 instead of on the hard disk box 2, it is more convenient to pull out the hard disk box 2 from the fixed seat 1 without having to consider the connection structure of the vibration damping mechanism 12.

[0048] In one embodiment of the present invention, please refer to Figure 5 The hard disk box 2 includes a housing and a hard disk body 26, and the hard disk body 26 is disposed inside the housing. The housing includes an upper shell 24 and a lower shell 24, and the upper shell 24 and the lower shell 24 are fixedly connected. The second cantilever portion 22 is integrally formed with the upper shell 24, and the first cantilever portion 21 and the lower shell 24 are integrally formed. The first cantilever portion 21 and the second cantilever portion 22 do not need to be separately processed and formed, which can reduce the processing cost. When the number of the first cantilever portions 21 is two, both of the two first cantilever portions 21 are disposed on the lower shell 24. The first cantilever portion 21 and the second cantilever portion 22 are separately formed, which is relatively easy to process. In other embodiments, the first cantilever portion 21 is integrally formed with the upper shell 24, and the second cantilever portion 22 is integrally formed with the lower shell 24.

[0049] Optionally, a plurality of heat dissipation holes 231 are formed on the housing to promote the heat dissipation of the hard disk body 26.

[0050] In one embodiment of the present invention, please refer to Figure 6 and Figure 7 One side of the box body 23 is provided with a first abutting portion 232, and the other side of the box body 23 is provided with a second abutting portion 233. The first abutting portion 232 is used to abut against one inner wall of the fixed seat 1, and the second abutting portion 233 is used to abut against the other inner wall of the fixed seat 1. The functions of the first abutting portion 232 and the second abutting portion 233 are to enable the box body 23 to be stably disposed in the fixed seat 1, and the box body 23 will not shake relative to the fixed seat 1. Here, the number of the first abutting portion 232 and the second abutting portion 233 is not limited, as long as the box body 23 does not shake when it is located inside the fixed seat 1. For example, the number of both the first abutting portion 232 and the second abutting portion 233 is two.

[0051] Optionally, at least one of the first abutting portion 232 and the second abutting portion 233 is cantilever-connected to the box body 23. In this way, at least one of the first abutting portion 232 and the second abutting portion 233 can be deformed under force. Even if there is a certain processing error in the fixed seat 1 or the housing of the hard disk box 2, the first abutting portion 232 and the second abutting portion 233 can be tightly abutted against the fixed seat 1.

[0052] Optionally, the first abutting portion 232 is cantilever-connected to the cartridge body 23. The first abutting portion 232 has a protrusion at a position away from its cantilever end, and the protrusion is used to abut against the inner wall of the fixing base 1. The second abutting portion 233 is provided as a protrusion on the surface of the cartridge body 23, and the side of the second abutting portion 233 facing the fixing base 1 is inclined, so that the hard disk cartridge 2 can smoothly slide into the fixing base 1 under the guidance of the second abutting portion 233.

[0053] In one embodiment of the present invention, please refer to Figure 6 and Figure 7 One end of the fixing base 1 away from the first engaging portion 11 is provided with a limiting spring buckle 13. The limiting spring buckle 13 is used to limit the position of the hard disk cartridge 2 relative to the fixing base 1 in the X direction, so as to prevent the hard disk cartridge 2 from exceeding the internal space of the fixing base 1 in the X direction when the hard disk cartridge 2 is inserted. The number of the limiting spring buckles 13 can be two, which are respectively arranged on opposite sides of the tail end of the fixing base 1. Among them, the end of the fixing base 1 provided with the first engaging portion 11 is the head end of the fixing base 1, and the other end of the fixing base 1 is the tail end of the fixing base 1.

[0054] Optionally, a positioning tongue 14 is provided at one end of the fixing base 1 close to the first engaging portion 11, and two positioning ribs 234 are provided on the cartridge body 23. When the hard disk cartridge 2 is inserted into the inside of the fixing base 1, the positioning tongue 14 gradually extends between the two positioning ribs 234. In this way, the cooperation of the two positioning ribs 234 and the positioning tongue 14 can limit the position of the hard disk cartridge 2 in the Y direction.

[0055] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
