Description

Technical Field

[0001] The utility model relates to the technical field of automobile cables, in particular to a segmented emergency cable device. Background Art

[0002] With the development of new energy vehicles, traditional automotive cables are gradually shifting towards electrification. For example, the fuel tank cap cable has been transformed into a door actuator, and the emergence of charging guns has led to the introduction of charging gun lock actuators. These changes have had a significant impact on traditional automotive cables. Traditional automotive cables need to transform with the electrification of vehicles. With the emergence of new products such as door actuators and charging gun lock actuators, emergency unlock cables have emerged. Pulling the emergency cable can unlock the door and charging gun in an emergency.

[0003] To facilitate the layout of the cable on the vehicle body and achieve a sealed connection with the vehicle body, the cable device in the prior art adopts the structure described in patent application number CN202222538323.9, entitled "Cable Device for Emergency Unlocking of a Charging Gun Inserted into a Vehicle Charging Port." The device includes a cable, an operating end, a flexible eyelet, an unlocking end, and a sleeve. The sleeve passes through the flexible eyelet and is fixedly connected to the flexible eyelet. The cable passes through the sleeve and slides within the sleeve. The operating end is provided at one end of the cable, and the unlocking end is fixed at the other end of the cable. The flexible eyelet is sealed and fixed to the vehicle body. During use, an external force acts on the operating end, driving the cable to move. The movement of the cable drives the unlocking end to move. The unlocking end is connected to the unlocking structure for emergency unlocking. The movement of the unlocking end can then achieve emergency unlocking of the vehicle door or charging gun.

[0004] The cable device of the above patent requires the combination of a sleeve and a flexible eyelet to achieve a sealed connection between the cable and the vehicle body, but this structure is only suitable for long-distance layouts. If the installation position of the cable is close to the emergency unlocking device of the charging gun, the sleeve cannot ensure that the cable moves along the predetermined route, resulting in the problem of being unable to unlock. In addition, the integrated structure of the cable is not conducive to on-site installation, resulting in the cable device in the prior art being unsuitable for layout and installation in small spaces. For this reason, it is necessary to provide a cable structure that can be installed in a small space and can achieve a sealed connection with the vehicle body. Utility Model Content

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] like Figure 1 、 2As shown, a segmented emergency cable device includes a cable and a protective cover 2. The cable is a split structure and includes a first cable 1 and a second cable 4. The first cable 1 passes through the protective cover 2 and is sealed and slidably connected to the protective cover 2. One end of the first cable 1 is the operating end 11, and the other end of the first cable 1 is detachably connected to the second cable 4. The end of the second cable 4 away from the first cable 1 is the unlocking end.

[0031] The protective cover 2 needs to be connected to the first cable 1 in a sliding and sealing manner, and also needs to be connected to the vehicle body in a sealing manner. To facilitate the installation of the protective cover 2, the protective cover 2 of the present invention is made of an elastic material, such as rubber. When the protective cover 2 is connected to the vehicle body, a punching hole is provided on the vehicle body, which means that the counterpart of the protective cover 2 is the connecting hole. For this purpose, the outer periphery of the protective cover 2 can be set into a circular ring structure, so that the protective cover 2 can be set in the connecting hole and achieve an interference fit with the connecting hole to achieve a sealed fixation. In order to further increase the sealing effect of the protective cover 2 and the connecting hole, as shown in FIG. Figure 1 、 3 As shown, a vertically outwardly extending annular sealing flange 21 is provided on the periphery of the protective sleeve 2. An annular groove 211 is also provided between the sealing flange 21 and the outer wall of the protective sleeve 2. During installation, the end of the connecting hole is embedded in the annular groove 211, and the sealing flange 21 and the end surface side wall of the connecting hole are squeezed and fixed. The sealing flange 21 can further achieve a sealed and fixed connection between the protective sleeve 2 and the connecting hole.

[0032] The outer wall of the protective cover 2 is sealed and fixed to the vehicle body, while the inner wall of the protective cover 2 requires a sealed and sliding connection with the first cable 1. To this end, the present invention provides at least one waterproof ring 23 protruding inwardly on the inner wall of the protective cover 2. The waterproof ring 23 forms an interference fit with the first cable 1. To enhance the strength and rust-proofing of the first and second cables 1 and 4 and to facilitate their use, in this embodiment, the first and second cables 1 and 4 each comprise a body composed of an internal metal rope and an externally wrapped plastic layer. The outer wall of the body of the first cable 1 is in a sealed and sliding connection with the protective cover 2. The metal rope ensures sufficient strength for the body. In this embodiment, the metal rope is a steel wire rope, constructed of high-carbon steel with a zinc-aluminum coating. The plastic layer is an externally coated nylon plastic. Of course, the plastic layer can also be a sleeve provided on the outside of the steel wire rope, secured to the steel wire rope using heat-sealing. The combination of steel wire rope and nylon plastic coating ensures that the first and second cables 1 and 4 possess sufficient strength while also exhibiting improved flexibility and corrosion resistance. This structure also reduces friction between the first cable 1 and the protective cover 2. To this end, based on the structure of the first cable 1, an inwardly projecting waterproof ring 23 is provided on the inner wall of the protective cover 2 to intercept foreign matter on the outer wall of the first cable 1, preventing it from passing through the connection hole and entering the vehicle body. This ensures that the protective cover 2 and the cables cooperate to achieve a sealed and sliding seal.

[0033] In another embodiment of the present invention, Figure 3 As shown, there are three waterproof rings 23, which are evenly distributed along the length of the inner wall of the protective cover 2. In this embodiment, three waterproof rings 23 are provided, and they are evenly distributed, considering the length of the inner hole of the protective cover 2, to further ensure the sealing effect between the first cable 1 and the protective cover 2.

[0034] In another embodiment of the present invention, in order to achieve a lightweight design for the protective cover 2 and also to reduce the injection molding material of the protective cover 2, a plurality of grooves 22 are provided on the main body of the protective cover 2 in this embodiment. The grooves 22 can reduce the material cost of the protective cover 2. Figure 1 、 3 As shown, in this embodiment, multiple grooves 22 are arranged inward along the end of the protective cover 2, and multiple grooves 22 are arranged in a ring along the inner hole of the protective cover 2. This layout is conducive to mold opening and facilitates injection molding production of the protective cover 2.

[0035] The protective cover 2, the first cable 1 and the vehicle body cooperate to ensure that the first cable 1 and the vehicle body can be sealed even when the cable assembly is removed from the sleeve, ensuring that the movement path of the entire cable is not restricted and that the movement of the cable can drive the emergency release device to unlock.

[0036] The cable of the present invention adopts a split structure, which is divided into a first cable 1 and a second cable 4. The first cable 1 passes through the protective cover 2 and is sealed and slidably connected to the protective cover 2. One end of the first cable 1 is the operating end 11, and the other end of the first cable 1 is detachably connected to the second cable 4. The end of the second cable 4 away from the first cable 1 is the unlocking end. The other end of the second cable 4 is fixed with a spherical connector 41, which is the unlocking end of the entire cable, and the connector 41 is installed in conjunction with the emergency unlocking device. Figure 1 、 2 As shown, the operating end 11 is a ring-shaped structure formed by bending one end of the first cable 1 and fixing it to the middle portion of the first cable 1. The end of the first cable 1 and the middle portion of the first cable 1 are fixed by a cable plug 12. The other end of the first cable 1 and the second cable 4 can be detachably connected by means of a snap connection, a threaded connection, or the like. For example, a threaded seat and a screw can be provided on the first cable 1 and the second cable 4, respectively, and the threaded seat and the screw seat can be connected in a coordinated manner to achieve detachable fixing of the first cable 1 and the second cable 4.

[0037] When the entire cable device is installed, the first cable 1 and the protective cover 2 are assembled, and the entire structure can be assembled with the vehicle body first, and then the unlocking end of the second cable 4 is connected to the emergency unlocking device, and finally the first cable 1 and the second cable 4 are fixed. The cable device of the utility model adopts a split structure on the basis of the existing structure. This structure can reduce the overall length of the cable, so that the entire cable device can meet the normal use (pulling) of the cable even if the sleeve is removed; at the same time, since the use of the sleeve can be reduced, the overall cost of the cable device can also be saved; and since the first cable 1 and the second cable 4 are a split structure, the installation of the protective cover 2 is not restricted, and the connection between the second cable 4 and the emergency unlocking device is also more convenient, so that the entire cable device is suitable for installation in a small space.

[0038] In another embodiment of the present invention, to facilitate the detachable connection between the first cable 1 and the second cable 4, a snap-fit ​​method is used in this embodiment to achieve the connection between the first cable 1 and the second cable 4. Specifically, the first cable 1 and the second cable 4 are detachably connected via a connector, which includes a cooperating snap joint 30 and a snap portion 3. The snap portion 3 and the snap joint 30 are respectively fixed to either the first cable 1 or the second cable 4. The snap portion 3 in this embodiment is injection molded from PBT material, but other materials similar to PBT can also be used to inject the snap joint 3. There are two ways to install the snap joint 3 and the snap joint 30 with the first cable 1 and the second cable 4. If the snap joint 3 is fixed to the first cable 1, the snap joint 30 and the second cable 4 are fixed; if the snap joint 3 and the second cable 4 are fixed, the snap joint 30 and the first cable 1 are fixed. This ensures that the first cable 1 and the second cable 4 can be detachably connected using the snap joint 3 and the snap joint 30. In this embodiment, the clamping joint 30 and the second cable 4 are fixed, and the first cable 1 and the clamping portion 3 are fixed.

[0039] In order to facilitate the detachable connection between the clamping joint 30 and the clamping part 3, the clamping part 3 is provided with a channel for the clamping joint 30 to pass through. The channel is divided into a feeding section 32 and a clamping section 35. A stop structure is provided between the feeding section 32 and the clamping section 35. The clamping joint 30 passes through the stop structure and is located in the clamping section 35 and is connected to the clamping part 3. The structure of the channel satisfies the movement of the clamping joint 30. In the absence of external force, the clamping joint 30 will not move in the opposite direction under the action of the stop structure, ensuring that the clamping joint 30 entering the clamping section 35 can be located in the clamping section 35, realizing a fixed connection between the clamping joint 30 and the clamping part 3. Since the clamping joint 30 and the second cable 4 are fixed, when the clamping joint 30 passes through the channel, in order to facilitate the movement of the second cable 4, the utility model is provided with a through groove 34 on the clamping section 35 for the first cable 1 or the second cable 4 to pass through. The through groove 34 is communicated with the feeding section 32 and the clamping section 35. Figure 7As shown, the clamping section 35 is a horizontally arranged through-cavity structure, one end of the through-cavity is communicated with the feed section 32, and the through-groove 34 passes through the side wall of the clamping section 35 in the vertical direction, thereby realizing the communication and connection between the through-groove 34 and the feed section 32 and the clamping section 35, ensuring that when the clamping joint 30 moves in the channel, the movement of the second cable 4 is not restricted.

[0040] The discharge end of the feed section 32 and the feed end of the clamping section 35 are transitionally connected by an arc section 36. The stop structure includes a stopper 33 protruding along the inner wall of the clamping section 35 or the feed section 32. A stop cavity is formed between the stopper 33 and the outer inner wall of the arc section 36, and the clamping block and the stop cavity are interference fit. In order to facilitate the coordination between the clamping part 3 and the clamping joint 30, the clamping joint 30 is usually set to a spherical structure. To this end, the feed section 32 and the clamping section 35 are connected by an arc section 36, and the arc section 36 fits the structure of the clamping joint 30. Of course, the arc section 36 can also adopt other structures, as long as it is ensured that the structure is compatible with the structure of the clamping joint 30. The position and structure of the stopper 33 only need to be compatible with the structure of the clamping joint 30, ensuring that the clamping joint 30 moves to the position between the arc section 36 and the stopper 33 during its passage through the channel, and is interference fit with the clamping joint 30. In this embodiment, as Figure 4 、 5 As shown in Figures 6 and 7, the feed section 32 is set vertically for easy layout, and the clamping section 35 is set horizontally. The upper end of the feed section 32 and one end of the clamping section 35 are connected through the arc section 36. The stopper 33 is set at the end position where the clamping section 35 and the arc section 36 are connected and is set vertically. A wedge structure is provided on the side of the stopper 33 close to the arc section 36. The setting of the wedge structure facilitates the clamping block to pass through the stopper 33 and enter the clamping section 35, and can also prevent the clamping joint 30 from retreating. Figure 8 As shown, the clamping joint 30 enters the clamping section 35 from the feed section 32 according to the path of (1)-(4) in the figure, wherein A in (2) indicates that the contact position of the clamping joint 30 and the inner wall of the anti-retraction cavity is interference fit, and the clamping joint 30 passing through the anti-retraction cavity enters the clamping section 35, completing the assembly of the clamping joint 30 and the clamping part 3. After the first cable 1 and the second cable 4 are assembled, the connector will naturally sag due to the action of gravity, and the anti-retraction structure can prevent the clamping joint 30 from falling out of the clamping part 3 when unlocking, thereby achieving the purpose of preventing it from falling out.

[0041] During the installation of the card connector 30, in order to observe whether the card connector 30 is installed in place, Figure 4 、 5 As shown in FIG. 7 , a communicating observation hole 31 is provided above the clamping section 35 , and the installation position of the clamping joint 30 can be observed through the observation hole 31 .

[0042] In the present invention, since the first cable 1 and the second cable 4 are used to control the switch of the charging gun emergency lock, according to the load-bearing capacity, lightweight design and adaptability to small space installation of the first cable 1 and the second cable 4, the diameter of the first cable 1 and the second cable 4 of this embodiment can be as small as 1 mm (wire rope diameter 0.8 mm), so that the space occupied by the cable device of the present invention is smaller and it is suitable for the installation and layout of various models.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
