Description

Technical Field

[0001] This utility model relates to the field of mining truck technology, specifically to a gear shifting mechanism for a mining truck cab. Background Technology

[0002] The gear shift control mechanism in the cab is an indispensable and crucial functional component inside a mining truck. Its design and layout not only profoundly affect the smoothness and safety of driving operations but also represent a perfect combination of aesthetics and practicality within the cab. Located in a central area easily accessible to the driver, this mechanism serves as a key bridge connecting the vehicle's power system and the driver's intentions. Traditional fixing methods often involve bolts directly penetrating the floor for fastening. While simple and direct, this design, over time, exposes the bolt heads to the complex and changing environment of the cab, making them highly susceptible to corrosion from humidity, dust, and chemicals. Severe corrosion not only affects aesthetics but also causes significant inconvenience when replacing or repairing the gear shift control mechanism, increasing maintenance costs and time.

[0003] Therefore, for modern mining trucks, how to innovate the fixing method of the gear shifting control mechanism to ensure its stability and reliability, effectively avoid rust problems, and at the same time take into account the overall aesthetics of the cab has become an important technical problem that urgently needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a gear shifting mechanism for a mining truck cab to solve the problem of corrosion caused by exposed bolts and mounting plates in the prior art.

[0005] This utility model provides a gear shifting mechanism for a mining truck cab, including a gear shift lever and a control assembly. A through hole is opened on the floor mounting surface corresponding to the position of the gear shift lever. The gear shift lever passes through the through hole and is connected to the control assembly. A gear shift sleeve is fitted on the outer side of the portion of the gear shift lever above the floor mounting surface. A gear shift cup is fixedly installed at the bottom end of the gear shift sleeve and is fixedly connected to the floor mounting surface. The gear shift cup is bowl-shaped and has a through hole at the bottom for the gear shift lever to pass through. Multiple fixing holes are opened on the bottom surface of the gear shift cup around the through hole. Fixing bolts are installed in the fixing holes to fix the gear shift cup to the floor mounting surface.

[0006] Furthermore, the manipulator assembly is provided with a connecting cavity for connecting to a floor mounting surface.

[0007] Furthermore, a shift mounting plate for fixed installation with the controller assembly is provided at the bottom of the connecting cavity.

[0008] Furthermore, the fixing hole has a through groove that connects to the through hole in the middle.

[0009] As a preferred embodiment, the outer end of the through groove is provided with a protrusion to prevent it from falling off.

[0010] As a preferred embodiment, the number of fixing holes in the shift cup is 4 to 8.

[0011] As a preferred embodiment, the upper surface of the gear shift lever is provided with an arc surface that conforms to the palm of the hand.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention solves the common problems in traditional installation methods and significantly improves user experience and overall product quality. By concealing the mounting point of the shift mechanism within the shift sleeve, it effectively avoids the problems of corrosion, loosening, and even failure caused by long-term direct exposure of the mounting bolts to the external environment, such as moisture, dust, and temperature changes. This ensures the stability and long-term reliability of the shift mechanism.

[0014] Furthermore, by concealing the mounting points, this invention significantly enhances the aesthetics and tidiness of the cab interior. In traditional designs, exposed bolts and mounting components often disrupt the harmony of the interior and negatively impact the visual experience. In contrast, this invention, through layout and concealment, makes the cab space appear more concise and aesthetically pleasing. Attached Figure Description

[0021] To illustrate the features of this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further explain this utility model.

[0022] Example:

[0023] Please see Figures 1 to 3This utility model provides a gear shifting mechanism for a mining truck cab, including a gear shift lever B1 and a control assembly B4. The upper surface of the gear shift lever B1 is provided with an arc surface that fits the palm. A through hole is opened on the floor mounting surface A1 corresponding to the position of the gear shift lever. The gear shift lever B1 passes through the through hole and is connected to the control assembly B4. The part of the gear shift lever B1 above the floor mounting surface A1 is fitted with a gear shift sleeve B2 on the outside. A gear shift cup B3 is fixedly installed at the bottom of the gear shift sleeve B2 and is fixedly connected to the floor mounting surface A1. The gear shift cup B3 is bowl-shaped and has a through hole at the bottom for the gear shift lever to pass through. Four fixing holes 1 are opened on the bottom surface of the gear shift cup around the through hole. Fixing bolts B31 are installed in the fixing holes 1 to fix the gear shift cup B3 to the floor mounting surface A1.

[0024] In addition, the portion below the floor mounting surface A1 is also protected in this embodiment. Specifically, the control assembly B4 is provided with a connecting cavity A2 to connect to the floor mounting surface A1, and a shift mounting plate A3 is provided at the bottom of the connecting cavity A2 for fixed installation with the control assembly B4, further increasing the stability of the connection.

[0025] To prevent the device from jamming and to facilitate removal of the fixed end when it is jammed, this embodiment provides a through groove 2 in the fixed hole 1 to connect the through hole in the middle, allowing the bolt to slide out of the through groove 2. In addition, this embodiment also provides an anti-loosening protrusion 3 at the outer end of the through groove 2 to prevent the bolt from easily coming out.
