Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an enhanced front handle structure for a commercial vehicle cab. Background Technology

[0002] The front panel handle is a handle located in the front panel area of ​​the cab of a commercial vehicle. Because commercial vehicles, such as trucks, are relatively tall, people need to step on vertical steps to get on and off the vehicle. Holding the front panel handle helps to reduce the difficulty of getting on and off the vehicle.

[0003] The existing front handle is fixed with bolts. If the person is tall, the handle is too high to reach and the arm span is not long enough to get a grip. If the person is short, the distance to the handle is too far and they have to stand on tiptoe. They also have to lean forward a lot and are prone to not being able to grip the handle tightly enough, which can cause it to slip and become unsafe. Summary of the Invention

[0004] This utility model provides an extended front handle structure for a commercial vehicle cab. The rear extension handle slides to the outside of the main handle and extends to a lower position, providing handle service at a lower position. The rear extension handle expands the range of use to accommodate a wider range of height differences, effectively solving the contradiction of traditional handles where "tall people cannot reach and short people need to stand on tiptoe". The side extension handle rotates around the handle pivot to achieve multi-angle adjustment. The side extension handle can be positioned closer to the inside of the vehicle than the main handle, providing the optimal grip position for passengers when getting out of the vehicle.

[0005] This utility model provides an extended front handle structure for a commercial vehicle cab, specifically including a main handle, a rear extension handle, and a side extension handle. The rear extension handle is slidably connected to the rear of the main handle, and a side extension handle is provided on the outer side of the main handle. Both ends of the main handle have through holes, which are M6 through holes with a spacing of 80mm. The mounting holes are used to connect and fix the main handle to the front of the vehicle cab with bolts. The main handle is made of ABS+PC alloy material with a tensile strength ≥60MPa. The front end of the main handle is fixedly connected to a handle shaft, and the outer side of the handle shaft has an outer sliding positioning hole in a circular array.

[0006] Furthermore, the tail extension handle is fixedly connected to an extension hook at its tail end, which limits the range of the grip when the user holds the handle. The tail extension handle has a threaded hole at its tail end. The supporting spring is made of 65Mn spring steel with an elastic coefficient of 15N / mm and a compression stroke of 10mm. The threaded hole is an M4 internal thread, which can be connected to a decorative cover plate to cover the mounting hole at the tail end of the main handle. The decorative cover plate is connected to the threaded hole at the tail end by an M4 screw, covering the mounting hole at the tail end of the main handle.

[0007] Furthermore, the tail extension handle slides axially outward toward the tail end of the main handle, with a sliding stroke of 50mm, enabling the handle to be provided at a lower position. The sliding extension of the tail extension handle expands the applicable height range from 160cm to 185cm to 150cm to 195cm.

[0008] The first end of the side extension handle is slidably connected to a positioning pin, and a support spring is fixedly connected between the positioning pin and the side extension handle. The first end of the side extension handle is fixedly connected to a side handle rotating seat, and the rotation angle range of the side extension handle is 0-180°.

[0009] Furthermore, the side handle rotating seat and the handle shaft at the head end of the side extension handle are rotatably connected, and the side handle rotating seat and the side extension handle are rotated around the handle shaft to adjust their direction and position.

[0010] Furthermore, the supporting spring supports the positioning pin, which moves toward the handle shaft side. The positioning pin and the outer sliding positioning hole are slidably connected. The head of the positioning pin is hemispherical and the insertion depth into the outer sliding positioning hole is ≥8mm.

[0011] Furthermore, when the positioning pin and the outer sliding positioning hole are slid in, the main handle and the side extension handle remain in a fixed state. Before the side extension handle is rotated, the positioning pin needs to be pulled to move away from the outer sliding positioning hole. After rotating into place, the positioning pin automatically inserts into the corresponding positioning hole under the action of the spring force to achieve locking. The main handle is horizontally downward for easy gripping when getting into the vehicle, and the side extension handle is located on the vertical and horizontal side of the main handle that is closer to the vehicle interior.

[0012] This utility model provides an enhanced front grab handle structure for a commercial vehicle cab, which has the following advantages: The tail extension handle slides to the outside of the main handle, and slides to a lower position to provide handle service at a lower position. The tail extension handle expands the range of use to meet a wider range of height differences, effectively solving the contradiction of traditional handles that are "too tall to reach and too short to stand on tiptoe".

[0013] The side extension handle can be adjusted to multiple angles by rotating around the handle pivot. The side extension handle can be positioned closer to the inside of the vehicle than the main handle, providing the optimal grip position for passengers when getting out of the vehicle and improving their stability.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Please refer to Figures 1 to 6 : This utility model proposes an extended front handle structure for a commercial vehicle cab, including a main handle 1, a rear extended handle 2, and a side extended handle 3. The main handle 1 has mounting holes 101 through-holes at both ends. These mounting holes 101 are M6 through holes with a spacing of 80mm. The mounting holes 101 are used to connect and fix the main handle 1 to the front of the vehicle cab with bolts. The main handle 1 is made of ABS+PC alloy material with a tensile strength ≥60MPa. A handle shaft 102 is fixedly connected to the front end of the main handle 1. An outer sliding positioning hole 103 is formed in a circular array on the outer side of the handle shaft 102. The rear extended handle 2 is slidably connected to the rear end of the main handle 1. An extension hook 201 is fixedly connected to the rear end of the rear extended handle 2. The extension hook 201 restricts the grip range when the user holds the handle. A threaded hole 202 is formed at the rear end of the rear extended handle 2. The supporting spring 302 is made of 65Mn spring. The spring steel has an elastic modulus of 15 N / mm and a compression stroke of 10 mm. The tail threaded hole 202 is an M4 internal thread, which can be connected to the decorative cover plate to cover the mounting hole 101 at the tail of the main handle 1. The decorative cover plate is connected to the tail threaded hole 202 by an M4 screw, covering the mounting hole 101 at the tail of the main handle 1. A side extension handle 3 is provided on the outside of the main handle 1. A positioning pin 301 is slidably connected to the head end of the side extension handle 3. A support spring 302 is fixedly connected between the positioning pin 301 and the side extension handle 3. A side handle rotating seat 303 is fixedly connected to the head end of the side extension handle 3. The rotation angle range of the side extension handle 3 is 0-180°. The side handle rotating seat 303 at the head end of the side extension handle 3 is rotatably connected to the handle shaft 102. The side handle rotating seat 303 and the side extension handle 3 rotate around the handle shaft 102 to adjust the direction and position.

[0019] In this embodiment, the tail extension handle 2 slides axially outward toward the tail end of the main handle 1. The support spring 302 supports the positioning pin 301 to move toward the handle shaft 102. The positioning pin 301 and the outer sliding positioning hole 103 are slidably connected. The head of the positioning pin 301 is hemispherical and the insertion depth into the outer sliding positioning hole 103 is ≥8mm. The tail extension handle 2 has a sliding stroke of 50mm, which enables the handle service to be provided at a lower position. The tail extension handle 2 expands the range of use. The sliding extension of the tail extension handle 2 expands the applicable height range from 160cm to 185cm to 150cm to 195cm, solving the contradiction of traditional handles that "tall people cannot reach and short people need to stand on tiptoe", and meeting a wider range of height differences.

[0020] In this embodiment, when the positioning pin 301 and the outer sliding positioning hole 103 are slid in, the main handle 1 and the side extension handle 3 remain in a fixed state. Before the side extension handle 3 is rotated, the positioning pin 301 needs to be pulled to move away from the outer sliding positioning hole 103. After being rotated into place, the positioning pin 301 automatically inserts into the corresponding positioning hole under the action of the spring force to achieve locking. The main handle 1 is horizontally downward for easy gripping when getting into the vehicle. The side extension handle 3 is located on the vertical and horizontal side of the main handle 1 that is closer to the inside of the vehicle, which satisfies the optimal gripping position when people get out of the vehicle.

[0021] In this second embodiment, based on the first embodiment, the tail extension handle 2 can be omitted, and the main handle 1 and the side extension handle 3 can be directly integrated. The positioning pin 301, support spring 302, side handle rotating seat 303, handle rotating shaft 102, and external sliding positioning hole 103 are all unnecessary, maximizing the reduction of the number of parts and further reducing costs.

[0022] The working principle of this embodiment: The main handle 1 is connected and fixed to the cab by bolts through the mounting holes 101. The main handle 1 is located on the inner side of the A-pillar, which connects the front door and the front bulkhead of the cab, near the windshield, or on the front bulkhead below the windshield on the driver's or passenger's side, above the dashboard. Personnel hold the main handle 1 for assistance when getting into the vehicle. Simultaneously, the rear extension handle 2 can slide to extend to the outside of the main handle 1, reaching a lower position to provide handle service. The rear extension handle 2 expands the range of use. The extended handle 2 expands the applicable height range from 160cm-185cm to 150cm-195cm, effectively solving the contradiction of traditional handles that are "too tall for tall people to reach and require tiptoeing for short people". For drivers with a height of ≤165cm, the downward extension of the handle reduces the height of the grip point from 85cm to 70cm, reducing the forward lean of the body by 30%. For users with a height of ≥185cm, the extended handle provides a more comfortable grip posture, increases the arm force area by 25%, and reduces muscle fatigue. Before rotating the side extension handle 3, the positioning pin 301 must be pulled to move and disengage from the outer sliding positioning hole 103. The limit of the side handle rotating seat 303 and the side extension handle 3 is released. After the side handle rotating seat 303 and the side extension handle 3 rotate around the handle shaft 102 to their positions, the positioning pin 301 is inserted into the corresponding outer sliding positioning hole 103 under the spring force of the support spring 302 to achieve locking. The side extension handle 3 and the side extension handle 3 rotate around the handle shaft 102 to achieve multi-angle adjustment. The main handle 1 is horizontal and downward, and the side extension handle 3 is vertical and horizontal. The side extension handle 3 is positioned closer to the vehicle interior than the main handle 1, providing the optimal grip position for passengers when getting out of the vehicle and improving their stability. The "enhanced" aspect is mainly reflected in the expansion of the traditional front handle's functions. Through the adjustability of the extension handle, such as its position and range, it can adapt to the gripping needs of people of different heights, providing more flexible and reliable grip support during passenger entry and exit, driver's cab operations, or emergency situations. This overcomes the limitations of traditional fixed-structure front handles in terms of usage scenarios and adaptability.
