Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicles, and particularly to a cable grommet assembly and a vehicle. Background Art

[0002] A grommet is a vehicle accessory used to seal the cable and the cable through-hole on the vehicle. For example, a vehicle usually has a bulkhead that divides the whole vehicle space into an engine compartment and a cab. One end of the engine compartment cable is connected to a lock body in the engine compartment, and the other end passes through the cable through-hole of the bulkhead and enters the cab, where it is connected to the engine compartment lock switch in the cockpit. Among them, the function of the grommet is to fix the cable and seal the cable through-hole on the bulkhead.

[0003] The existing grommet is fixed. When an operator connects the cable in the cab to the engine compartment lock switch, the operator needs to operate with the head down and repeatedly adjust the length of the cable extending into the cab. If the cable extending into the cockpit is too short and the cable cannot reach the engine compartment lock switch, the operator needs to pull the cable forcefully; if the cable extending into the cockpit is too long and the cable accumulates and bends in the cab, it is easy to bump against the instrument panel, then the operator needs to get out of the vehicle and squat down at the engine compartment position to pull the cable outwards. Therefore, when adjusting the cable length, the position needs to be repeatedly switched, which consumes the physical strength of the operator and slows down the production rhythm, resulting in a reduction in production efficiency.

[0029] Regarding the technical problem of inconvenient adjustment of the pull wire in the prior art, as Figure 1 shown, the present disclosure provides a pull wire rubber plug assembly, including:

[0030] A rubber plug body 1, the rubber plug body 1 having a hollow inner cavity 101;

[0031] A telescopic part 2, the telescopic part 2 having a first pull wire through hole 201, the first pull wire through hole 201 communicating with the hollow inner cavity 101 for the pull wire 4 to pass through; the telescopic part 2 is connected to one end of the rubber plug body 1 and can be retracted into the hollow inner cavity 101.

[0032] Exemplarily, the rubber plug body 1 and the telescopic part 2 can be made of a stretchable rubber material, and the rubber plug body 1 having the hollow inner cavity 101 and the telescopic part 2 form a telescopic structure. Figure 1 The structure of the telescopic part 2 in the natural state (non-contracted state) is shown. The telescopic part 2 extends a preset length away from the rubber plug body 1, and the extended length can be adjusted.

[0033] Taking the wire rope grommet assembly applied to the wire rope through-hole on the vehicle's front bulkhead as an example, the front bulkhead divides the vehicle space into two parts: the engine compartment and the cab. Among them, the telescopic part 2 is arranged at one end of the grommet body 1 extending into the cab. When the length of the wire rope 4 extending into the cab is too long, the operator can push the wire rope 4 back towards the engine compartment, and the wire rope 4 drives the telescopic part 2 to move towards the grommet body 1 and contract into the hollow inner cavity 101 of the grommet body 1; when the length of the wire rope 4 extending into the cab is insufficient, the operator can pull the wire rope 4 towards the cab, and the wire rope 4 drives the telescopic part 2 away from the hollow inner cavity 101 of the grommet body 1, so that the length of the wire rope 4 extending into the cab can be flexibly adjusted inside the cab, without the operator repeatedly switching positions, saving physical strength and improving production efficiency.

[0034] In this embodiment, the wire rope grommet assembly can be extended by 14 mm and can be shortened by 14 mm, and the total adjustment amount is 28 mm. The adjustment amount of the wire rope grommet assembly can be designed according to the needs of the actual application scenario, not limited to 28 mm. The adjustment amount is related to the length of the telescopic part 2 and the length of the hollow inner cavity 101.

[0035] It should be noted that the wire rope grommet assembly of the present disclosure can be applied not only to the front bulkhead of the vehicle, but also to the wire rope through-holes in other parts of the vehicle, for fixing the wire rope and sealing the wire rope through-hole, and having the function of adjusting the length of the wire rope.

[0036] As an alternative embodiment, as Figure 1 shown, one end of the grommet body 1 connecting the telescopic part 2 is a conical structure 102, and the conical structure 102 has a preset thickness.

[0037] Specifically, the thickness of the conical structure 102 determines the force for the grommet to expand and contract. Figure 2 As shown, in this embodiment, the preset thickness H can be 1 mm, and the required force is about 10 N. Using a thinner conical wall helps the telescopic part 2 to contract into the hollow inner cavity 101 of the grommet body 1. If the conical wall of the conical structure 102 is too thick, it will cause the telescopic part 2 to be unable to contract back into the hollow inner cavity 101, or the operator needs to exert a greater force to push the telescopic part 2 back into the hollow inner cavity 101, resulting in inconvenient use.

[0038] As an alternative embodiment, as Figure 2 shown, the conical structure 102 and the telescopic part 2 are connected to form an included angle A with a preset angle; wherein, the preset angle A is greater than 90 degrees and less than 145 degrees.

[0039] Specifically, the angle between the conical structure 102 and the telescopic part 2 must be an obtuse angle, that is, greater than 90 degrees, so that the telescopic part 2 can contract. This angle determines the adjustment length of the rubber plug. The larger this angle is, the larger the adjustable range of the rubber plug is. However, correspondingly, the adjustment is more laborious, and the manufacturing cost of the rubber plug is also higher. Therefore, the preset angle is not the larger the better, and it needs to be adjusted according to the actual application scenario to select a suitable angle. In this embodiment, the preset angle A is 140 degrees, and the corresponding adjustment length is plus or minus 14 mm, that is, the telescopic part 2 can extend 14 mm towards the cab or contract 14 mm towards the engine room direction.

[0040] As an alternative embodiment, as Figure 1 shown, the telescopic part 2 is connected with the pull wire 4 in an interference fit manner, and the inner diameter of the telescopic part 2 is smaller than the outer diameter of the pull wire 4.

[0041] Exemplarily, as Figure 1 shown, the outer diameter D1 of the pull wire 4 is 4.2 mm, and the inner diameter D2 of the telescopic part 2 is 4 mm. The outer diameter D1 of the pull wire 4 is slightly larger than the inner diameter D2 of the telescopic part 2 to achieve an interference fit connection. Utilizing the elasticity of the material of the telescopic part 2, the first pull wire through hole 201 is expanded and deformed to sleeve on the pull wire 4, and the first pull wire through hole 201 generates a tightening force on the pull wire 4 to connect the two parts. The interference fit is a type of tight fit connection method, mainly used for the fastening connection where relative movement between the hole and the shaft is not allowed. The interference fit connection method between the telescopic part 2 and the pull wire 4 determines the force for the mutual sliding between the pull wire 4 and the telescopic part 2 (about 40 N in this embodiment), so that the pull wire 4 and the telescopic part 2 can expand and contract as a whole, realizing the length adjustment function of the pull wire.

[0042] As an alternative embodiment, as Figure 3 shown, the pull wire rubber plug assembly further includes:

[0043] The limiting part 3, which is connected to the other end of the rubber plug body 1. The limiting part 3 has a second pull wire through hole 301, which is communicated with the hollow inner cavity 101.

[0044] Specifically, as Figure 3 shown, the limiting part 3 is located in the space of the engine room, which can prevent the rubber plug body 1 from disengaging from the front panel pull wire through hole 501 on the front panel 5 when adjusting the length of the pull wire 4, thus resulting in the loss of the sealing function.

[0045] As an alternative embodiment, as Figure 3 shown, the pull wire rubber plug assembly is used to seal the front panel 5 of the vehicle; the outer diameter of the other end of the rubber plug body 1 is adapted to the diameter D5 of the front panel pull wire through hole 501 on the front panel 5, and the outer diameter D4 of the limiting part 3 is greater than the diameter D5 of the front panel pull wire through hole 501.

[0046] Exemplarily, as Figure 3As shown, the diameter D5 of the wire through-hole 501 in the front bulkhead in this embodiment is 16 mm. To prevent the limiting part 3 from passing through the wire through-hole 501 in the front bulkhead when pulling the wire 4, the outer diameter D4 of the limiting part 3 can be appropriately designed to be larger, for example, 21 mm, to increase the clamping strength between the rubber plug and the front bulkhead 5. One end of the rubber plug body 1 passing through the wire through-hole 501 in the front bulkhead can adopt an inverted trapezoidal structure, and its minimum outer diameter can be equal to or slightly larger than the diameter of the wire through-hole 501 in the front bulkhead, ensuring that the rubber plug body 1 can pass through the wire through-hole 501 in the front bulkhead and play a sealing role.

[0047] As an alternative embodiment, as Figure 3 shown, a pair of clamping grooves 6 are provided at the connection between the limiting part 3 and the rubber plug body 1 for fixing the rubber plug body 1 on the front bulkhead 5.

[0048] Specifically, the outer diameter of the limiting part 3 is larger than the diameter of the wire through-hole 501 in the front bulkhead. The narrower end of the inverted trapezoidal structure of the rubber plug body 1 is connected to the limiting part 3, forming the clamping groove 6, thereby fixing the entire wire rubber plug assembly on the front bulkhead 5 to prevent it from moving freely.

[0049] As an alternative embodiment, as Figure 2 and 3 shown, the outer diameter D3 of the telescopic part 2 is smaller than the diameter D6 of the hollow inner cavity 101.

[0050] Exemplarily, the telescopic part 2 can adopt a cylindrical structure, with an outer diameter D3 of 7.3 mm and a length of 14 mm. The telescopic part 2 is connected to the narrower end of the conical structure 102. The diameter D6 of the hollow inner cavity 101 in this embodiment is 11 mm, which should be larger than the outer diameter D3 of the telescopic part 2 to provide an avoidance space when the telescopic part 2 contracts.

[0051] The present disclosure also provides a vehicle, as Figure 3 shown, including an engine compartment, a cab, and a front bulkhead 5 for separating the engine compartment and the cab. The front bulkhead 5 is provided with a wire through-hole 501 in the front bulkhead; it also includes the wire rubber plug assembly in any one of the above embodiments, including:

[0052] A rubber plug body 1, the rubber plug body 1 having a hollow inner cavity 101;

[0053] A telescopic part 2, the telescopic part 2 having a first wire through-hole 201, the first wire through-hole 201 communicating with the hollow inner cavity 101 for the wire 4 to pass through; the telescopic part 2 is connected to one end of the rubber plug body 1 and can be contracted into the hollow inner cavity 101.

[0054] In this embodiment, the rubber plug body 1 with a hollow inner cavity 101 and the telescopic part 2 form a telescopic structure. The telescopic part 2 can extend a preset length away from the rubber plug body 1, and the extended length can be adjusted; it can also contract towards the hollow inner cavity 101, so as to flexibly adjust the length of the wire in the cab, without the operator repeatedly switching positions to adjust the length of the wire, saving physical strength and improving production efficiency.

[0055] It should be understood that various forms of the processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved, and no limitations are imposed herein.

[0056] The above specific embodiments do not constitute a limitation on the protection scope of this disclosure. Those skilled in the art should understand that various modifications, combinations, sub - combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure shall be included within the protection scope of this disclosure.
