[0044] The vehicle-mounted device usually needs multiple cables to realize the connection between each electrical device in the vehicle-mounted device to realize the function of the vehicle-mounted device. In order to ensure that each electrical device can be stably connected and will not be disconnected from the electrical device to be connected due to shaking, an external fixing structure is usually used to fix the cable. The most common way is to bundle one or more cables with a nylon cable tie to avoid the vehicle-mounted device from moving with the vehicle, which causes the cable to shake, and then causes the signal transmission of each electrical device connected by the cable to be poor or disconnected, which affects the performance of the vehicle-mounted device. However, this way is time-consuming and labor-intensive, which affects the installation efficiency. When the vehicle-mounted device needs to be removed or replaced from the vehicle, the operator needs to untie the cable tie one by one, which is complicated to operate.

[0045] In view of this, please refer to Figure 1 and Figure 2 The cable fixing device 100 provided by the present application comprises a base 110 and a cover 120. The cover 120 is rotatably connected with the base 110. The base 110 is provided with a first groove 111. When the cover 120 rotates towards the direction in which the included angle between the cover 120 and the base 110 decreases and abuts against the base 110, a fixing channel 160 for the cable 250 is formed between the cover 120 and the first groove 111. When the cover 120 rotates away from the base 110, the fixing channel 160 disappears.

[0046] The base 110 and the cover 120 of the cable fixing device 100 are rotatably connected, which can make the cover 120 abut against the base 110 to realize the buckled state of the cable fixing device 100, so as to fix the cable by using the formed fixing channel 160, and can also make the cover 120 away from the base 110 to realize the opened state of the cable fixing device 100, so as to release the cable from the fixing, and facilitate the arrangement or arrangement of the cable. Figure 1 The structure schematic diagram of the cable fixing device 100 provided by the embodiment of the application in the buckled state is shown, Figure 2 The structure schematic diagram of the cable fixing device 100 provided by the embodiment of the application in the opened state is shown.

[0047] As shown in Figure 1 and Figure 2 , the cover 120 is rotatably connected with the base 110 at least at one end, so that the cover 120 can rotate relative to the base 110 within a certain angle range. A plurality of first grooves 111 can be arranged on the base 110, and when the included angle between the cover 120 and the base 110 gradually decreases until the cover 120 abuts against the base 110, the cable fixing device 100 is shown in Figure 1 , the cover 120 and the first groove 111 form a fixing channel 160 for the cable 250 to pass through, so as to realize the fixing and management of the cable. When the cover 120 rotates away from the base 110, the included angle between the cover 120 and the base 110 increases, Figure 1 , the fixing channel 160 in disappears, and the cable can be released from the fixing.

[0048] When the cable fixing device 100 is shown in Figure 2 as the opened state, i.e. the cover is away from the base 110, the operator can place the cable to be fixed on the first groove 111 to realize the preliminary positioning and fixing of the cable to be fixed. After the operator places each cable on the first groove 111, the cover 120 is rotated to abut against the base 110, so that the cable fixing device 100 remains in the buckled state as shown in Figure 1 , to fix the cable and prevent the cable from moving.

[0049] The number of the first grooves 111 can be set to be multiple, i.e. a plurality of fixing channels 160 are arranged on a single cable fixing device 100, so that a single cable fixing device 100 can fix a plurality of cables, thereby reducing the number of cable fixing devices 100 required to be arranged on the vehicle-mounted equipment 200, improving the installation efficiency and reducing the occupied space. The specific shape of the fixing channel 160 is not limited in the embodiment, as long as it can accommodate the cable, for example, if the cable is in the form of a round bar, the fixing channel 160 is in the form of a hollow cylinder with open front and rear ends.

[0050] In one embodiment, the cross-sectional area of ​​the fixing channel 160 is less than or equal to the cross-sectional area of ​​the cable, so that when the cable is fixed in the fixing channel 160, the outer surface of the cable is in contact with or even in an interference fit with the channel surface of the fixing channel 160, thereby stably fixing the cable in the fixing channel 160. It is understood that even when the cross-sectional area of ​​the fixing channel 160 is set to be less than the cross-sectional area of ​​the cable, the size of the cross-sectional area of ​​the fixing channel 160 is still sufficient for the cable to be placed.

[0051] Continue to refer to Figure 1 and Figure 2 and combined Figure 3 The base 110 is provided with a switch assembly 130 movable relative to the base 110, the switch assembly 130 including a first latch 131. The cover 120 is provided with a second latch 133. When the cover 120 rotates towards the base 110 until it abuts against the base 110, the first latch 131 and the second latch 133 engage. The switch assembly 130 is configured to move in a direction that disengages from the second latch 133 when subjected to force.

[0052] The base 110 and the cover 120 are connected and separated by a switch assembly 130. Specifically, a first latch 131 is provided on the base 110, and a corresponding second latch 133 is provided on the cover 120. When the cover 120 rotates towards the base 110 and abuts against the base 110, the first latch 131 and the second latch 133 engage, thus achieving a fixed connection between the cover 120 and the base 110. When it is necessary to release the cover 120 from the base 110, i.e., separate them, a force is applied to the switch assembly 130 to make it move along... Figure 2 Moving the cable in the direction indicated by the arrow disconnects the second latch 133 from the first latch 131, allowing the cover 120 to rotate away from the base 110 and separate from it. In this embodiment, the cable can be fixed and released simply by operating the switch assembly 130, thereby improving the convenience and efficiency of installation.

[0053] For details, please continue to refer to Figure 1 to Figure 3 and combined Figure 4 to Figure 6 The switch assembly 130 includes a pressing member 135, a first buckle 131 disposed on the pressing member 135, and a receiving groove 112 disposed on the base 110. The receiving groove 112 has a mounting through hole 113 and a mounting countersunk hole 114 respectively on opposite sides. The first buckle 131 is disposed in the receiving groove 112, and the pressing member 135 is movably disposed through the mounting through hole 113, the receiving groove 112 and the mounting countersunk hole 114.

[0054] Figure 4 This is a schematic diagram of the internal structure of the base without the switch assembly installed in the embodiments of this application. Figure 5 and Figure 6The internal structure of the cable fixing device in use and in open state is shown respectively. The base 110 is provided with a receiving groove 112 for accommodating the first buckle 131. As shown in Figure 4 , the left side of the receiving groove 112 is provided with a mounting through hole 113, and the right side of the receiving groove 112 is provided with a mounting counter bore 114. The receiving groove 112 is used for accommodating the first buckle 131, and the first buckle 131 is provided with a through slot for the pressing piece 135 to pass through. The through slot is in communication with the mounting through hole 113 and the mounting counter bore 114 when the first buckle 131 is placed in the receiving groove 112. As shown in Figure 5 , the pressing piece 135 is sequentially arranged in the mounting through hole 113, the through slot and the mounting counter bore 114. The pressing piece 135 is connected with the first buckle 131. When it is needed to separate the cover 120 from the base 110, the user applies force to the pressing piece 135 to move it to the left side, so that the first buckle 131 moves to the left side in the receiving groove 112 until the first buckle 131 is separated from the second buckle 133 to release the fixing of the cable. The size of the receiving groove 112 can be greater than that of the first buckle 131, so that the first buckle 131 can move in the receiving groove 112.

[0055] More specifically, with continued reference to Figure 3 to Figure 6 , the cable fixing device 100 further comprises a first elastic piece 140 arranged in the mounting counter bore 114. One end of the first elastic piece 140 is connected with the pressing piece 135. When the pressing piece 135 is pressed down, the first elastic piece 140 is compressed. When the pressing piece 135 is released, the first elastic piece 140 pushes the pressing piece 135 to move to the right side under the action of the elastic force, so that the first buckle 131 also moves to the right side with the pressing piece 135, realizing the automatic reset of the switch assembly 130 which can move on the base 110. Specifically, the extension direction of the first elastic piece 140 can be parallel to the moving direction of the pressing piece 135. When the pressing piece 135 is not forced, at least part of the structure of the first elastic piece 140 extends out of the receiving groove 112 and is connected with the pressing piece 135.

[0056] In some embodiments of the present application, with continued reference to Figure 4 to Figure 6 , the side of the first buckle 131 away from the base 110 is provided with a first guide inclined surface 132, and the side of the second buckle 133 away from the cover 120 is provided with a second guide inclined surface 134. The inclination directions of the first guide inclined surface 132 and the second guide inclined surface 134 are the same.

[0057] The first guide slope 132 and the second guide slope 134 are used to enable the second buckle 133 to be smoothly matched with the first buckle 131 when the cover 120 is rotated to abut against the first buckle 131 and the second buckle 133, reduce abrasion caused by multiple matching, improve the durability of the switch assembly 130, and further ensure smooth operation feeling during opening and closing of the cover 120 and the base 110. The first guide slope 132 and the second guide slope 134 are in the same direction, when the cover 120 gradually approaches the base 110, the second guide slope 134 on the second buckle 133 first contacts the first guide slope 132 of the first buckle 131, converts the downward force of the second buckle 133 into the leftward force of the first buckle 131, so that the first buckle 131 moves leftward; when the cover 120 completely abuts against the base 110, the first elastic member 140 is pushed to move the first buckle 131 rightward under the restoring action, so that the first buckle 131 and the second buckle 133 are mutually buckled to be as shown in Figure 5 .

[0058] In some embodiments of the present application, the cable fixing device 100 further comprises a second elastic member 150, the two ends of the second elastic member 150 are respectively connected with the cover 120 and the base 110, and the second elastic member 150 is configured to be elastically deformed when the cover 120 is rotated towards the base 110.

[0059] As shown in Figure 3 to Figure 6 , the two ends of the second elastic member 150 are respectively connected with the cover 120 and the base 110, when the cover 120 is rotated to approach the base 110, the second elastic member 150 is elastically deformed due to compression or stretching, and the deformation of the second elastic member 150 can provide an auxiliary force to help the first buckle 131 and the second buckle 133 to be more stably buckled, thereby enhancing the reliability of locking.

[0060] In the embodiments of the present application, the second elastic member 150 is a torsion spring, the base 110 is further provided with a base 110 shaft hole, the cover 120 is further provided with a cover 120 shaft hole, the base 110 shaft hole and the cover 120 shaft hole are connected through a rotating shaft 151, the second elastic member 150 is sleeved on the rotating shaft 151, and one end of the second elastic member 150 is connected with or abuts against the cover 120, and the other end of the second elastic member 150 is connected with or abuts against the base 110, so that the second elastic member 150 is in the open state as shown in Figure 2 under the condition of no external force, and remains in this state. When it is needed to change the cable fixing device 100 to the buckled state as shown in Figure 1 , the torsion spring is deformed due to external force, one end of the cover 120 rotates around the rotating shaft 151, and the other end of the cover 120 moves downward to approach the base 110. When it is needed to change the cable fixing device 100 from the use state to the open state, i.e., from Figure 1 toFigure 2 When the first buckle 131 and the second buckle 133 are separated, the second elastic member 150 will return to the initial state under the elastic force due to the loss of external force, thereby driving the cover body 120 to rotate around the rotating shaft 151 from the position shown in Figure 1 to the position shown in Figure 2 .

[0061] The cable fixing device 100 of the present application is provided with the second elastic member 150. When it is necessary to release the cable from being fixed, the cover body 120 is automatically reset to the original position due to the force of the second elastic member 150, thereby improving the efficiency of fixing or reorganizing the cable. The rotatable connection of the base 110 and the cover body 120 is realized through the rotating shaft 151. Compared with other ways of realizing the overturning of the cover body 120 relative to the base 110, such as hinge connection, hinge joint or bearing connection, the structure is small and simple. Through the cooperation of the rotating shaft 151 and the second elastic member 150, the elastic potential energy of the second elastic member 150 is utilized to realize the automatic reset of the cover body 120 when the base 110 and the cover body 120 are opened, which is convenient, fast and labor-saving.

[0062] Further, with reference to Figure 1 to Figure 6 , the cover body 120 is provided with a second groove 121. When the cover body 120 rotates to abut against the base 110 in the direction in which the included angle between the cover body 120 and the base 110 decreases, the first groove 111 and the second groove 121 cooperate to form a fixing channel 160 for the cable to pass through and fix the cable.

[0063] The cover body 120 is specially designed with one or more second grooves 121. The second grooves 121 cooperate with the first grooves 111 on the base 110 to form the fixing channel 160 when the cover body 120 abuts against the base 110. The fixing channel 160 not only allows the cable to pass through, but also can fix the cable to prevent the cable from moving or falling off. In the present embodiment, the first grooves 111 and the second grooves 121 can all be semicircular grooves, so that the cross section of the fixing channel 160 formed is circular to adapt to the shape of the cable, thereby improving the stability of the cable in the fixing channel 160. The number of the first grooves 111 and the second grooves 121 corresponds, and the size and number of the fixing channel 160 formed by the first grooves 111 and the second grooves 121 are set according to the size and number of the cable.

[0064] Among them, as Figure 1 to Figure 6As shown, the first groove 111 and the second groove 121 are arranged along the width direction of the base 110. That is, the fixing channel 160 formed by the first groove 111 and the second groove 121 is arranged along the width direction of the base 110, so that a plurality of fixing channels 160 can be arranged along the length direction of the base 110, so as to arrange more fixing channels 160 without increasing the volume of the cable fixing device, thereby adapting to different installation environments and space requirements.

[0065] In some embodiments of the present application, the side of the cover 120 away from the base 110 is in a grid pattern. The grid pattern can reduce the weight of the cover 120, and make it easier to flip the cover 120 of the cable fixing device 100 more quickly when it is uncoupled. The overall structure of the cable fixing device 100 is lighter, and the installation operability is stronger. When the cable fixing device 100 is applied to the vehicle-mounted equipment 200, the shock resistance of the cable fixing device 100 can be enhanced, and the stability of the cable fixing device 100 can be enhanced.

[0066] Next, the working principle of the cable fixing device 100 will be described with reference to the embodiment shown in Figure 1 to Figure 6 When it is needed to enter the use state, the cover 120 will gradually approach the base 110 under the action of an external force, the first buckle 131 and the second buckle 133 are coupled with each other, so as to realize the fixed connection of the cover 120 and the base 110, and at the same time, the second elastic member 150 is compressed. At this time, it is the state shown in Figure 1 When it is needed to change from the use state to the open state, the pressing member 135 is pressed down, the first elastic member 140 is compressed, so that the first buckle 131 and the second buckle 133 are separated, and then under the action of the second elastic member 150, the cover 120 is driven to rotate around the rotating shaft 151 from the position shown in Figure 1 to the position shown in Figure 2 According to another aspect of the present application, please continue to refer to Figure 1 to Figure 3 and in combination with Figure 7 The present application also provides a vehicle-mounted equipment 200, which comprises the cable fixing device 100 of any one of the above embodiments, and the cable 250 is arranged in the fixing channel 160 of the cable fixing device 100.

[0067] The vehicle-mounted equipment 200 includes but is not limited to vehicle-mounted lighting equipment, vehicle-mounted audio amplifier, vehicle-mounted frequency interference instrument and the like. The vehicle-mounted equipment 200 is usually connected by a cable 250 and installed on a vehicle body.

[0068] In some embodiments of the present application, the vehicle-mounted equipment 200 comprises a base 210. The base 110 of the cable fixing device 100 further comprises a fixing hole 116 which can be mounted with a fastener. The cable fixing device 100 is detachably connected to the base 210 through the fastener. As shown in Figure 1 to Figure 3 and Figure 7As shown, the base 210 of the vehicle-mounted device 200 functions to receive each module or electrical component in the vehicle-mounted device 200 and mount the vehicle-mounted device 200 on the vehicle body. An operator mounts the cable fixing device 100 on the base 210 according to the arrangement of the cables 250 in the vehicle-mounted device 200 and places the cables 250 in the fixing channels 160 to fix the cables 250. The base 110 is detachably connected to the base 210, so that when the vehicle-mounted device 200 needs to be removed from the vehicle or replaced, the cable fixing device 100 can be removed from the vehicle-mounted device 200, and the removed cable fixing device 100 can be mounted on the vehicle-mounted device 200 to be replaced, thereby being reusable and avoiding resource waste.

[0069] For the vehicle-mounted frequency interference instrument, it is usually required to be placed on the roof of the vehicle, and it is difficult to assemble on the roof. The cable fixing device 100 provided in the embodiment can fix the cables 250 by pressing and can conveniently and quickly release the cables 250.

[0070] In some embodiments of the present application, the vehicle-mounted device 200 includes a functional module 220 and an antenna module 230, and the cable fixing device 100 is located between the functional module 220 and the antenna module 230. The functional module 220 is connected to the antenna module 230 through the cables 250.

[0071] The vehicle-mounted device 200 in the embodiments of the present application is taken as an example of a vehicle-mounted frequency interference instrument for emitting interference signals to the environment. As shown in Figure 7 The vehicle-mounted frequency interference instrument is connected to the functional module 220 (a radio frequency module in the embodiments of the present application) and the antenna module 230 through a plurality of cables 250 to realize signal transmission between the two. The functional module 220 is used to output radio frequency signals and transmit them to the antenna module 230, and the antenna module 230 is used to emit the radio frequency signals transmitted from the functional module 220. The cable fixing device 100 is located between the antenna module 230 and the functional module 220, and the cable fixing device 100 is mounted on the vehicle-mounted device 200 according to the arrangement of the cables 250, so that each cable 250 can pass through the fixing channels 160 of the cable fixing device 100, and the working of the vehicle-mounted device 200 will not be affected by the loosening of the cables 250 due to movement of the vehicle, which can cause unstable connection or failure of the antenna module 230 and the functional module 220.

[0072] Continuing to refer to Figure 1 to Figure 7 and in combination with Figure 8In some embodiments of the present application, the vehicle-mounted device 200 comprises a plurality of sets of cable fixing devices 100, which comprise primary cable fixing devices 100a and secondary cable fixing devices 100b. The primary cable fixing devices 100a are arranged between the functional module 220 and the secondary cable fixing devices 100b, and the secondary cable fixing devices 100b are arranged between the antenna module 230 and the primary cable fixing devices 100a.

[0073] The specific structures of the primary cable fixing devices 100a and the secondary cable fixing devices 100b are the same as those of the cable fixing device 100 described above, and the difference lies in the different positions at which they are placed. Each cable 250 is connected to at least two cable fixing devices 100, at least one of which (i.e., the primary cable fixing device 100a) is arranged close to the functional module 220, and at least one of which (i.e., the secondary cable fixing device 100b) is arranged close to the antenna module 230. As shown in Figure 7 The arrangement of at least two sets of cable fixing devices 100 between the functional module 220 and the antenna module 230 in the manner of multi-point fixing of the cables 250 can better fix the cables 250, thereby ensuring the working stability of the vehicle-mounted device 200. The primary cable fixing devices 100a and the secondary cable fixing devices 100b can be multiple, and all the primary cable fixing devices 100a are arranged in a line along the Y direction, and all the secondary cable fixing devices 100b are also arranged in a line along the Y direction. The secondary cable fixing devices 100b and the primary cable fixing devices 100a are arranged in sequence along the X direction, respectively.

[0074] If the antenna module 230 adopts an inverted V-shaped antenna, i.e., the antenna can rotate, in order to avoid the pulling of the cables 250 connected to the interface of the functional module 220 caused by the rotation of the antenna, the primary cable fixing devices 100a are arranged close to the functional module 220 in this embodiment, so as to ensure that the cables 250 between the functional module 220 and the primary cable fixing devices 100a remain unchanged and are not affected by the antenna module.

[0075] In addition, the cable fixing devices 100 close to the functional module 220 are arranged as the primary cable fixing devices 100a, and the cable fixing devices close to the antenna module 230 are arranged as the secondary cable fixing devices 100b, so that the cable fixing devices 100 can not only fix both ends of each cable 250, but also limit the arrangement direction of the cables 250, thereby facilitating the arrangement, arrangement and fixing of the cables 250 by the operator when assembling the vehicle-mounted device 200.

[0076] In some embodiments of the present application, please continue to refer to Figure 1 to Figure 8The antenna module 230 has a collapsed position and a working position. The cable fixing device 100 also includes a tertiary cable fixing device 100c, which is located between the primary cable fixing device 100a and the secondary cable fixing device 100b. The fixing channel 160 of the tertiary cable fixing device 100c and the fixing channel 160 of the secondary cable fixing device 100b are located on one side of the collapsed position.

[0077] There can be multiple Class III cable fixing devices 100c, and all Class III cable fixing devices 100c are arranged in a row along the Y direction. Figure 8 The three rows of cable fixing devices 100 arranged from left to right, from functional module 220 to antenna module 230, are referred to as primary cable fixing device 100a, tertiary cable fixing device 100c, and secondary cable fixing device 100b, respectively. Primary cable fixing device 100a is used to fix the cable 250 just leading from functional module 220, preventing the cable from breaking off due to the antenna module 230 shaking with the vehicle. Secondary cable fixing device 100b is used to further fix multiple cables leading from functional module 220 and guides the arrangement of the cable 250.

[0078] The third-level cable fixing device 100c is set between the first-level cable fixing device 100a and the second-level cable fixing device 100b. The setting of the third-level cable fixing device 100c allows for a slack in the cable 250 between the first-level cable fixing device 100a and the third-level cable fixing device 100c, which acts as a buffer when the antenna module 230 shakes and pulls the cable 250.

[0079] Please refer to some embodiments of this application. Figure 7 and Figure 8 Antenna module 230 may include multiple antennas. The antennas of antenna module 230 can extend along... Figure 7 Rotate in the direction of the middle arrow. For example... Figure 7 The state shown represents the working position of antenna module 230. In this position, all antennas are vertical and can transmit signals upwards. If antenna module 230 is not needed, it can be rotated to the folded-down position, where the antennas are parallel to the base 210, facilitating antenna storage. The vehicle-mounted device 200 includes a limiting seat 240, corresponding to the antenna arrangement in antenna module 230. When antenna module 230 is in the folded-down position, each antenna abuts against the limiting seat 240. The limiting seat 240 prevents excessive rotation of the antennas in antenna module 230 and also supports and secures the folded-down antennas, preventing them from swaying due to vehicle movement and protecting antenna module 230.

[0080] Further, the fixing channels 160 of the tertiary cable fixing device 100c and the fixing channels 160 of the secondary cable fixing device 100b are located on the side of the lying position, specifically, the fixing channels 160 of each tertiary cable fixing device 100c and the fixing channels 160 of each secondary cable fixing device 100b do not coincide with the lying position of any antenna. Therefore, for the same cable 250 passing through the fixing channels 160 of the tertiary cable fixing device 100c and the fixing channels 160 of the secondary cable fixing device 100b, the fixing channels 160 are located on the same side of the lying position of the adjacent antennas. For example, the tertiary cable fixing device 100c is staggered with the limiting seat 240, so that each cable 250 connecting the antenna module 230 and the functional module 220 is distributed between the adjacent antennas. Therefore, when each antenna is in the lying position, it will not collide with the cable 250, but will be located on one side of the cable 250 to avoid interference of the cable 250 on the antenna lying.

[0081] Specifically, the height of the antenna module 230 in the lying position is higher than the height of the functional module 220, and the height of the tertiary cable fixing device 100c and the secondary cable fixing device 100b is higher than the height of the primary cable fixing device 100a. Therefore, the present embodiment can constrain the arrangement of the cable 250 in cooperation with the tertiary cable fixing device 100c and the secondary cable fixing device 100b to adapt to the arrangement of each antenna. Specifically, each cable 250 in the tertiary cable fixing device 100c and the secondary cable fixing device 100b can be parallel to the antenna in the lying position. For the primary cable fixing device 100a, since it is close to the functional module 220 and the interfaces of the functional module 220 are concentrated, in order to make the cable better connected with the functional module 220, the primary cable fixing device 100a can also be arranged more compactly. By reasonably arranging the multiple groups of cable fixing devices 100 and controlling the direction of the cable 250, the antenna lying position can be avoided to ensure that the cable 250 does not affect the lying or moving of the antenna, and the connection between the cable 250 and the functional module 220 and the antenna module 230 can be more stable.

[0082] The vehicle-mounted equipment 200 of the embodiment of the present application realizes flexible arrangement and efficient operation of the cables 250 by arranging a plurality of cable fixing devices 100. Specifically, the base 110 and the cover 120 are rotationally connected, and the fixed channel 160 is formed when the base 110 and the cover 120 abut, thereby effectively fixing the cables 250, avoiding that the cables 250 are pulled or moved to cause disconnection or poor contact of the vehicle-mounted equipment 200, and avoiding that the cables 250 are entangled with each other and are not easy to maintain. When the cover 120 is rotated away from the base 110, the cables 250 are released from the fixing, thereby facilitating the operator to arrange or rearrange the cables 250 as necessary. This design greatly improves the convenience and flexibility of cable 250 management, and also reduces the maintenance difficulty, so that the operator can quickly respond to various cable 250 adjustment and fixing requirements, and improves the overall work efficiency and the use experience of the equipment.
