Description

Technical Field

[0001] This utility model relates to a fixing structure, and more specifically, it relates to a fixing structure for a vehicle-mounted data transfer hard drive. Background Technology

[0002] Onboard data transfer hard drives are data transfer devices used on railway vehicles. They are plug-and-play while the vehicle is in motion. However, due to the inevitable shaking and vibration during vehicle movement, onboard data transfer hard drives need to have good vibration resistance. Currently, most onboard data transfer hard drives are directly plugged into an interface, with the connection completely exposed. Vibrations during vehicle movement can easily cause the hard drive to loosen or make poor contact, and over time, the interface may even deform. To prevent this, some onboard hard drives have complex external fixing and shock-absorbing structures, but these make the hard drive not plug-and-play and unsuitable for use with plug-and-play onboard data transfer hard drives.

[0003] For example, Chinese Patent Publication No. 212804068U, published on March 26, 2021, discloses a utility model entitled "A Vehicle-Mounted Hard Drive Shock Absorption Device and a Vehicle-Mounted Hard Drive Shock Absorption System." This application discloses a vehicle-mounted hard drive shock absorption device, including a left shock absorption bracket, a right shock absorption bracket, four shock absorbers, and a hard drive enclosure mounting shell. The device absorbs shock by fixing two of the four shock absorbers between the left shock absorption bracket and the left side of the hard drive enclosure mounting shell, with the two annular protrusions of the two shock absorbers contacting the left side. The other two shock absorbers are fixed between the right shock absorption bracket and the right side of the hard drive enclosure mounting shell, with the two annular protrusions of the other two shock absorbers contacting the right side. Each shock absorber is integrally formed by in-mold hot pressing of damping rubber or damping silicone and stainless steel hardware. The stainless steel hardware increases the strength of the shock absorber, and the damping silicone or damping rubber with a damping coefficient greater than a preset threshold increases the shock absorber's vibration absorption capacity, improves its service life, and further enhances the durability of the shock absorption performance stability. While this solution can effectively dampen and secure the vehicle hard drive, its structure is too complex and it is not suitable for plug-and-play vehicle hard drives. Utility Model Content

[0004] This invention overcomes the problem of poor fixation of plug-and-play vehicle hard drives during use, and provides a vehicle hard drive fixation structure. This solution can not only provide good shock absorption for the vehicle hard drive, but also prevent the vehicle hard drive from becoming loose or having poor contact.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a vehicle-mounted hard drive fixing structure, including a fixing base, the fixing base having a plug-in cavity adapted to the hard drive, the plug-in cavity having an insertion hole on one side and a plug-in hole on the other side, the fixing base having a fixing part adapted to the plug-in cavity located outside the plug-in cavity, the fixing part being located on one side of the plug-in hole, and the cavity wall of the plug-in cavity also having a positioning component. In this solution, the plug-in cavity on the fixing base is used to plug in the hard drive body, and the fixing part on the fixing base is used to connect with the plug-in cavity, fixing both the fixing base and the hard drive to the plug-in cavity, thereby achieving overall fixing of the plug-in cavity, the fixing base, and the hard drive. The positioning component positions and fixes the hard drive within the fixing base. Even if a certain amount of vibration occurs inside the vehicle, under the action of the fixing base, the hard drive and the plug-in cavity will not produce a large vibration amplitude, achieving a good shock absorption effect and preventing the hard drive from loosening.

[0006] Preferably, the positioning assembly includes a positioning hole on the cavity wall and a positioning element located within the positioning hole. The positioning assembly is used to limit the movement of the hard disk within the insertion cavity.

[0007] Preferably, the positioning element is an elastic ball-head positioning post, including a ball head and a positioning post. The ball head faces the insertion cavity, and the positioning post is disposed within the positioning hole. The positioning element is used to position the hard drive and prevent it from becoming loose. The ball head faces the inside of the insertion cavity and is used to limit and fix the hard drive within the cavity.

[0008] Preferably, the hard drive has a spherical limiting groove on its side corresponding to the positioning component, and the spherical limiting groove is adapted to the ball head. The spherical limiting groove can limit the ball head of the positioning component, thereby making the hard drive stably fixed on the mounting base and preventing the hard drive from becoming loose.

[0009] Preferably, the fixing parts are symmetrically arranged on both sides of the insertion hole, and the insertion socket is provided with fixing holes that are adapted to the fixing parts. The fixing parts are used to connect with the insertion holes on the insertion socket, thereby fixing the insertion socket and ensuring the relative fixation between the hard drive and the insertion socket, reducing the impact of vibration on the hard drive.

[0010] Preferably, the positioning hole is a through hole that penetrates the cavity wall. Designing the positioning hole as a through hole facilitates the installation and removal of the positioning component and makes maintenance easier.

[0011] Preferably, the connector is provided with an interface, the hard drive is provided with a slot, and the interface is adapted to the slot.

[0012] Preferably, the insertion hole is adapted to the maximum radial dimension of the hard disk. When the insertion hole is adapted to the external dimensions of the hard disk, the cavity wall of the cavity can limit the movement of the hard disk surface when the hard disk is inserted into the insertion cavity, preventing it from shaking or reducing the amplitude of vibration.

[0013] Preferably, the radial dimension of the plug hole is larger than the radial dimension of the interface and the socket. To facilitate connection between the interface and the socket, the size of the plug hole needs to be larger than the size of the interface and the socket.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) This solution can realize plug-and-play hard disks, effectively reduce vibration during vehicle operation, and prevent hard disks from becoming loose; (2) This solution has a simple structure, is easy to use, and can effectively protect the connection parts of hard disks and devices.

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0021] Example 1: As Figures 1 to 4 The illustrated vehicle-mounted data transfer hard drive mounting structure includes a mounting base 1, a connector 3, and a hard drive 2. The mounting base 1 connects the connector 3 and the hard drive 2, while the connector 3 can be directly connected to the connector 2.2 of the hard drive 2. In this embodiment, the vehicle-mounted data transfer hard drive is a plug-and-play type, and will be referred to as hard drive 2 below.

[0022] The mounting base 1 is a cuboid structure. Inside the mounting base 1 is a insertion cavity 1.1, which is adapted to the outer surface of the hard disk 2. In this embodiment, the insertion cavity 1.1 is a cuboid hollow structure, while the hard disk 2 is shaped like a USB flash drive. The two sides of the insertion cavity 1.1 are insertion holes 1.2 and 1.3, respectively. That is, insertion holes 1.2 and 1.3 are located on opposite sides of the mounting base 1, and the insertion cavity 1.1 is a through-cavity on both sides of the mounting base 1. Insertion hole 1.2 serves as the structure for inserting the hard disk 2, and insertion hole 1.3 serves as the structure for connecting the hard disk 2 and the mounting base 3. Therefore, insertion holes 1.3 and 1.2 are also rectangular.

[0023] A fixing part 1.4 is also provided on the fixing base 1, and the fixing part 1.4 is arranged on the outside of the fixing base 1. Specifically, the fixing part 1.4 is a cylindrical plug structure, and two sets of fixing parts 1.4 are provided, and are located on one side of the plug hole 1.3 of the fixing base 1. Since the plug hole 1.3 is the connection position between the hard disk 2 and the plug socket 3, the fixing part 1.4 needs to be located on this side and fixedly connected to the plug socket 3. The fixing parts 1.4 are symmetrically arranged on both sides of the plug hole 1.3 and distributed along the length direction of the cross section of the plug hole 1.3.

[0024] Furthermore, the connector 3 is a structure of the vehicle-mounted transmission equipment. The connector 3 includes an interface 3.2, while the hard drive 2 has a socket 2.2. The socket 2.2 of the hard drive 2 can be inserted into the interface 3.2 on the connector 3 for data transmission. Both the socket 2.2 and the interface 3.2 are existing technologies and will not be described in detail here.

[0025] A fixing hole 3.1 is also provided on the connector 3, which mates with the fixing part 1.4 on the fixing base 1. The fixing hole 3.1 is a circular hole and is symmetrically distributed on both sides of the interface 3.2. Specifically, the two sets of fixing holes 3.1 are distributed along the length direction of the cross section of the interface 3.2. The length of the fixing part 1.4 on the fixing base 1 needs to be greater than the length of the interface 3.2 on the connector 3, and when the fixing part 1.4 on the fixing base 1 is engaged with the fixing hole 3.1 on the connector 3, the interface 3.2 on the connector 3 should be exactly located at the position of the connector hole 1.3 on the fixing base 1 (e.g., ...). Figure 3 or Figure 4 As shown in the diagram, the connection between hard disk 2 and interface 3.2 will be located within the insertion cavity 1.1, which protects the connection between hard disk 2 and the transmission device.

[0026] A positioning component 4 is also provided on the fixing base 1. The positioning component 4 is arranged on the cavity wall of the insertion cavity 1.1 and is used to position and fix the body of the hard disk 2, ensuring that the hard disk 2 is fixed in position within the insertion cavity 1.1. The positioning component 4 includes a positioning element 4.1 and a positioning hole 4.2. The positioning hole 4.2 is a hole structure arranged on the cavity wall, and the positioning element 4.1 is arranged inside the positioning hole 4.2. When the body of the hard disk 2 is inserted into the insertion cavity 1.1, the positioning element 4.1 can abut against the surface of the body of the hard disk 2, thereby fixing and limiting the body of the hard disk 2.

[0027] Furthermore, the size of the insertion hole 1.2 is adapted to the size of the hard drive 2 body. The size of the insertion hole 1.2 is larger than the size of the connector hole 1.3, and the size of the connector hole 1.3 is larger than the size of the interface 3.2 of the connector 3 and the socket 2.2 of the hard drive 2. A chamfer is also provided on one side of the insertion hole 1.2, which eliminates stress on the edge of the insertion hole 1.2 and facilitates the insertion of the hard drive 2 into the connector cavity 1.1. When the hard drive 2 is inserted into the connector cavity 1.1, the cavity wall of the connector cavity 1.1 can limit the movement of the hard drive 2, thereby preventing the hard drive 2 from shaking due to vehicle vibration. The cooperation between the interface 3.2 and the socket 2.2, and the cooperation between the connector cavity 1.1 and the hard drive 2 body, greatly ensures the anti-shaking and anti-loosening effect of the hard drive 2. In addition, the size of the plug hole 1.3 is larger than the size of the interface 3.2 of the plug socket 3 and the socket 2.2 of the hard disk 2, which can avoid the interface 3.2 of the plug socket 3 and the socket 2.2 of the hard disk 2, and facilitate the connection between the interface 3.2 and the socket 2.2.

[0028] The steps for using this solution are as follows: First, align the two fixing parts 1.4 on the fixing base 1 with the two fixing holes 3.1 on the plug-in base 3, and engage the fixing parts 1.4 with the fixing holes 3.1, so that the interface 3.2 on the plug-in base 3 partially enters the plug-in hole 1.3. At this point, the fixing base 1 can be fixed to the transmission equipment on the vehicle. Then, align one end of the hard disk 2's connector 2.2 with the insertion hole 1.2 of the fixing base 1, and align the position of the hard disk 2's connector 2.2 with the position of the interface 3.2 on the plug-in base 3 (align the length and width of the rectangle respectively). Then, insert the hard disk 2 into the plug-in cavity 1.1 of the fixing base 1 until the connector 2.2 on the hard disk 2 is inserted into the interface 3.2 on the plug-in base 3, completing the connection between the hard disk 2 and the transmission equipment.

[0029] Example 2: As Figures 1 to 4 The illustrated vehicle-mounted data transfer hard drive mounting structure includes a mounting base 1, a connector 3, and a hard drive 2. The mounting base 1 connects the connector 3 and the hard drive 2, while the connector 3 can be directly connected to the connector 2.2 of the hard drive 2. In this embodiment, the vehicle-mounted data transfer hard drive is a plug-and-play type, and will be referred to as hard drive 2 below.

[0030] The mounting base 1 is a cuboid structure. Inside the mounting base 1 is a insertion cavity 1.1, which is adapted to the outer surface of the hard disk 2. In this embodiment, the insertion cavity 1.1 is a cuboid hollow structure, while the hard disk 2 is shaped like a USB flash drive. The two sides of the insertion cavity 1.1 are insertion holes 1.2 and 1.3, respectively. That is, insertion holes 1.2 and 1.3 are located on opposite sides of the mounting base 1, and the insertion cavity 1.1 is a through-cavity on both sides of the mounting base 1. Insertion hole 1.2 serves as the structure for inserting the hard disk 2, and insertion hole 1.3 serves as the structure for connecting the hard disk 2 and the mounting base 3. Therefore, insertion holes 1.3 and 1.2 are also rectangular.

[0031] A fixing part 1.4 is also provided on the fixing base 1, and the fixing part 1.4 is arranged on the outside of the fixing base 1. Specifically, the fixing part 1.4 is a cylindrical plug structure, and two sets of fixing parts 1.4 are provided, and are located on one side of the plug hole 1.3 of the fixing base 1. Since the plug hole 1.3 is the connection position between the hard disk 2 and the plug socket 3, the fixing part 1.4 needs to be located on this side and fixedly connected to the plug socket 3. The fixing parts 1.4 are symmetrically arranged on both sides of the plug hole 1.3 and distributed along the length direction of the cross section of the plug hole 1.3.

[0032] Furthermore, the connector 3 is a structure of the vehicle-mounted transmission equipment. The connector 3 includes an interface 3.2, while the hard drive 2 has a socket 2.2. The socket 2.2 of the hard drive 2 can be inserted into the interface 3.2 on the connector 3 for data transmission. Both the socket 2.2 and the interface 3.2 are existing technologies and will not be described in detail here.

[0033] A fixing hole 3.1 is also provided on the connector 3, which mates with the fixing part 1.4 on the fixing base 1. The fixing hole 3.1 is a circular hole and is symmetrically distributed on both sides of the interface 3.2. Specifically, the two sets of fixing holes 3.1 are distributed along the length direction of the cross section of the interface 3.2. The length of the fixing part 1.4 on the fixing base 1 needs to be greater than the length of the interface 3.2 on the connector 3, and when the fixing part 1.4 on the fixing base 1 is engaged with the fixing hole 3.1 on the connector 3, the interface 3.2 on the connector 3 should be exactly located at the position of the connector hole 1.3 on the fixing base 1 (e.g., ...). Figure 3 or Figure 4 As shown in the diagram, the connection between hard disk 2 and interface 3.2 will be located within the insertion cavity 1.1, which protects the connection between hard disk 2 and the transmission device.

[0034] A positioning component 4 is also provided on the fixing base 1. The positioning component 4 is arranged on the cavity wall of the insertion cavity 1.1 and is used to position and fix the body of the hard disk 2, ensuring that the hard disk 2 is fixed in position within the insertion cavity 1.1. The positioning component 4 includes a positioning element 4.1 and a positioning hole 4.2. The positioning hole 4.2 is a hole structure arranged on the cavity wall, and the positioning element 4.1 is arranged inside the positioning hole 4.2. When the body of the hard disk 2 is inserted into the insertion cavity 1.1, the positioning element 4.1 can abut against the surface of the body of the hard disk 2, thereby fixing and limiting the body of the hard disk 2.

[0035] Specifically, in this embodiment, two sets of positioning components 4 are provided, and are respectively arranged on opposite sides of the fixed base 1. The positioning element 4.1 is an elastic ball-head positioning post, comprising a ball head 4.11 and a positioning post 4.12. The ball head 4.11 and the positioning post 4.12 are integrally formed. The ball head 4.11 is located at one end of the positioning post 4.12, and the radial dimension of the ball head 4.11 is larger than the radial dimension of the positioning post 4.12. The end of the ball head 4.11 faces the insertion cavity 1.1 of the fixed base 1, and part of the ball head 4.11 is located inside the insertion cavity 1.1. The positioning post 4.12 is located in the positioning hole 4.2 on the cavity wall of the insertion cavity 1.1. The insertion cavity 1.1 is a rectangular cavity, and the two sets of positioning holes 4.2 are arranged on opposite sides of the fixed base 1, as shown below. Figure 3 As shown, in this embodiment, the positioning hole 4.2 is arranged on the upper and lower surfaces of the fixing base 1. The positioning hole 4.2 penetrates the cavity wall of the insertion cavity 1.1, and a countersunk hole is provided at the inner end of the positioning hole 4.2 (the end facing the insertion cavity). Since the radial dimension of the ball head 4.11 on the positioning member 4.1 is larger than the radial dimension of the positioning post 4.12, the ball head 4.11 can be snapped into place at the position of the countersunk hole. Since the positioning member 4.1 is made of elastic material, the positioning member 4.1 can be easily assembled. The countersunk hole can limit and snap the ball head 4.11.

[0036] Similarly, a spherical limiting groove 2.1 is provided on the surface of the hard disk 2 corresponding to the positioning component 4. The spherical limiting groove 2.1 is arranged at one end of the hard disk 2 body where the insertion port 2.2 is located. One end of the spherical limiting groove 2.1 is located at the end of the hard disk 2 body, so that the ball head 4.11 of the positioning component 4.1 can enter the spherical limiting groove 2.1. The other end of the spherical limiting groove 2.1 is located on the surface of the hard disk 2. In this way, when the hard disk 2 is inserted into the insertion socket 3, the ball head 4.11 of the positioning component 4.1 can abut against the spherical limiting groove 2.1, thereby positioning the hard disk 2 and preventing the hard disk 2 from becoming loose.

[0037] Furthermore, the size of the insertion hole 1.2 is adapted to the size of the hard drive 2 body. The size of the insertion hole 1.2 is larger than the size of the connector hole 1.3, and the size of the connector hole 1.3 is larger than the size of the interface 3.2 of the connector 3 and the socket 2.2 of the hard drive 2. A chamfer is also provided on one side of the insertion hole 1.2, which eliminates stress on the edge of the insertion hole 1.2 and facilitates the insertion of the hard drive 2 into the connector cavity 1.1. When the hard drive 2 is inserted into the connector cavity 1.1, the cavity wall of the connector cavity 1.1 can limit the movement of the hard drive 2, thereby preventing the hard drive 2 from shaking due to vehicle vibration. The cooperation between the interface 3.2 and the socket 2.2, and the cooperation between the connector cavity 1.1 and the hard drive 2 body, greatly ensures the anti-shaking and anti-loosening effect of the hard drive 2. In addition, the size of the plug hole 1.3 is larger than the size of the interface 3.2 of the plug socket 3 and the socket 2.2 of the hard disk 2, which can avoid the interface 3.2 of the plug socket 3 and the socket 2.2 of the hard disk 2, and facilitate the connection between the interface 3.2 and the socket 2.2.

[0038] The steps for using this solution are as follows: First, align the two fixing parts 1.4 on the fixing base 1 with the two fixing holes 3.1 on the plug-in base 3, and engage the fixing parts 1.4 with the fixing holes 3.1, so that the interface 3.2 on the plug-in base 3 partially enters the plug-in hole 1.3. At this point, the fixing base 1 can be fixed to the transmission equipment on the vehicle. Then, align one end of the hard disk 2's connector 2.2 with the insertion hole 1.2 of the fixing base 1, and align the position of the hard disk 2's connector 2.2 with the position of the interface 3.2 on the plug-in base 3 (align the length and width of the rectangle respectively). Then, insert the hard disk 2 into the plug-in cavity 1.1 of the fixing base 1 until the connector 2.2 on the hard disk 2 is inserted into the interface 3.2 on the plug-in base 3, completing the connection between the hard disk 2 and the transmission equipment.
