Description
Technical Field
[0001] The invention belongs to the technical field of transmission oil dipstick disassembly, and in particular relates to a transmission oil dipstick disassembly and assembly structure, an oil dipstick and a vehicle. Background Art
[0002] During routine maintenance and inspection of automotive transmissions, the oil dipstick, a key component for monitoring the oil level and status inside the transmission, is crucial for ease and accuracy in installation and removal. Accurate and convenient installation and removal of the dipstick ensures technicians can obtain timely and effective information about the transmission's oil content, providing a reliable basis for proper operation and maintenance.
[0003] Currently, traditional transmission dipstick removal and installation methods mostly rely on direct manual operation, requiring technicians to rely on the grip of their fingers to pull the dipstick out of the transmission or insert it. However, this method has many drawbacks. First, due to the often confined space inside the transmission, the dipstick may be blocked by other components, making it difficult for technicians to obtain sufficient operating space and exert flexible force, thus increasing the difficulty of removing and installing the dipstick. Second, after prolonged or frequent removal and installation operations, technicians' fingers are prone to fatigue due to repeated exertion, which not only reduces work efficiency but can also damage the dipstick or related transmission components due to operational errors, affecting the normal performance and service life of the transmission.
[0004] In addition, under some special working conditions, such as when the transmission is in a high temperature state, the surface temperature of the oil dipstick will also rise. Direct manual operation may cause burns to the technician, posing a major safety hazard. Moreover, with the continuous development of the automotive industry, the structure of the transmission is becoming increasingly complex, and the requirements for the accuracy and efficiency of the oil dipstick disassembly and assembly are also becoming higher and higher. The traditional manual direct operation method can no longer meet the needs of modern transmission maintenance and repair. Summary of the Invention
[0005] The purpose of the present invention is to provide a transmission oil dipstick disassembly and assembly structure, an oil dipstick and a vehicle, so as to solve the technical defect that the traditional manual direct operation method can no longer meet the needs of modern transmission maintenance and repair.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, a transmission oil dipstick disassembly and assembly structure is provided, comprising: Grip; A connecting piece is fixed to the outside of the gripping portion and is perpendicular to the gripping portion; A hook assembly, provided at the end of the connector, for hooking the oil dipstick; When the gripping portion rotates, the hook assembly drives the oil dipstick to be assembled and disassembled.
[0007] Furthermore, the hook assembly includes: A bottom plate is provided at an end of the connecting member away from the grip portion; The hooks are symmetrically arranged on the bottom of the base plate.
[0008] Furthermore, the bottom plate includes: a horizontal end and a curved end, wherein the horizontal end and the curved end are an integral structure, and the horizontal end is fixed to the connecting member; The two hooks are both installed on the horizontal end; wherein, the bending angle of the bent end is greater than or equal to the bending angle of the hook.
[0009] Furthermore, the bent end is axially perpendicular to the connecting piece.
[0010] Furthermore, the connecting piece is welded to the middle portion of the horizontal end.
[0011] Furthermore, the connecting piece is a tubular or rod-shaped structure.
[0012] Furthermore, the bending direction of the bent end is opposite to the bending direction of the hook.
[0013] Furthermore, the gripping portion is a tubular, rod-shaped, ring-shaped or triangular structure.
[0014] In a second aspect, an oil dipstick is provided, which is disassembled and assembled using the transmission oil dipstick disassembly and assembly structure as described above.
[0015] According to a third aspect, a vehicle is provided, comprising the oil dipstick as described above.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Traditional manual operation of the oil dipstick is difficult in transmissions with limited space and numerous obstructing components. This new assembly and disassembly mechanism utilizes a grip that rotates to activate a hook assembly, allowing the operator to remove and assemble the dipstick. This eliminates the need for operators to reach into a confined space to grasp the dipstick; they can simply operate the grip from the outside. This significantly reduces operational difficulty and improves efficiency in complex environments.
[0017] 2. The hooks are symmetrically arranged at the bottom of the base plate. When the dipstick is hooked, the force acting on the dipstick is evenly distributed, avoiding the dipstick from shaking or slipping due to uneven force, ensuring that the dipstick remains stable during disassembly and assembly, and improving the reliability and safety of operation.
[0018] 3. The integrated structure can better disperse these forces, making the overall force on the bottom plate more uniform, thereby enhancing the structural strength and stability of the entire hook assembly and reducing the risk of failure caused by loose or broken parts.
[0019] 4. The axially vertical design enables the force transmitted from the grip to the connector to act more directly on the bent end and the hook.
[0020] 5. Welding the connecting piece in the middle of the horizontal end can make the hook assembly reach a balanced state when subjected to force. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.
[0025] During routine maintenance and inspection of automotive transmissions, the oil dipstick, a key component for monitoring the oil level and status inside the transmission, is crucial for ease and accuracy in installation and removal. Accurate and convenient installation and removal of the dipstick ensures technicians can obtain timely and effective information about the transmission's oil content, providing a reliable basis for proper operation and maintenance.
[0026] Currently, traditional transmission dipstick removal and installation methods mostly rely on direct manual operation, requiring technicians to rely on the grip of their fingers to pull the dipstick out of the transmission or insert it. However, this method has many drawbacks. First, due to the often confined space inside the transmission, the dipstick may be blocked by other components, making it difficult for technicians to obtain sufficient operating space and exert flexible force, thus increasing the difficulty of removing and installing the dipstick. Second, after prolonged or frequent removal and installation operations, technicians' fingers are prone to fatigue due to repeated exertion, which not only reduces work efficiency but can also damage the dipstick or related transmission components due to operational errors, affecting the normal performance and service life of the transmission.
[0027] In addition, under some special working conditions, such as when the transmission is in a high temperature state, the surface temperature of the oil dipstick will also rise. Direct manual operation may cause burns to the technician, posing a major safety hazard. Moreover, with the continuous development of the automotive industry, the structure of the transmission is becoming increasingly complex, and the requirements for the accuracy and efficiency of the oil dipstick disassembly and assembly are also becoming higher and higher. The traditional manual direct operation method can no longer meet the needs of modern transmission maintenance and repair.
[0028] To address the technical deficiencies mentioned in the background art, this embodiment provides a transmission oil dipstick assembly and disassembly structure, an oil dipstick, and a vehicle. The present invention is further described in detail below with reference to the accompanying drawings: In a first aspect, an embodiment of the present invention provides a transmission oil dipstick disassembly and assembly structure, such as Figure 1 and Figure 2 As shown, it includes: a gripping portion 100; a connecting member 200, which is fixed to the outside of the gripping portion 100 and is axially perpendicular to the gripping portion 100; a hooking assembly 300, which is provided at the end of the connecting member 200 and is used to hook the oil dipstick 20; wherein, when the oil dipstick 20 is disassembled or assembled, the hooking assembly 300 is hooked to the outside of the oil dipstick 20, and when the gripping portion 100 is held and rotated, the hooking assembly 300 drives the oil dipstick 20 to rotate, thereby realizing the disassembly and assembly operation.
[0029] like Figure 3 and Figure 4As shown, the oil dipstick structure installed on the transmission includes a crossbar 10, a dipstick 20, a sealing gasket 30, and an oil dipstick scale area 40. The dipstick 20 is connected to the crossbar 10 at one end and threaded to the oil dipstick scale area 40 at the other end. The sealing gasket 30 is installed between the dipstick 20 and the oil dipstick scale area 40, and is located outside the connection between the two. Given the limited space inside the transmission and the numerous obstructing components surrounding it, traditional manual operation of the oil dipstick is difficult to perform. However, the hook assembly 300 of the disassembly structure is hooked onto the outside of the crossbar 10, and the grip 100 rotates to drive the hook assembly 300, thereby enabling the disassembly and assembly of the oil dipstick 20. The operator no longer needs to reach into the narrow space to directly grasp the oil dipstick 20; they only need to operate the grip 100 from the outside. This greatly reduces the difficulty of operation and improves work efficiency in complex spatial environments.
[0030] When the operator rotates the gripping portion 100, the force is transmitted to the hook assembly 300 through the connecting member 200. Compared with directly grasping the oil dipstick 20 with the hands, this structure enables the operator to complete the disassembly and assembly of the oil dipstick 20 with less force, thereby reducing the operator's physical burden. The advantage is more obvious especially when performing frequent disassembly and assembly operations of the oil dipstick 20.
[0031] In addition, when the transmission is running at high temperature, the surface temperature of the oil dipstick 20 will also increase, and there is a risk of burns if it is directly operated by hand. Using this disassembly and assembly structure, the operator does not need to directly touch the oil dipstick 20, avoiding direct contact with the high-temperature oil dipstick 20, and effectively ensuring the personal safety of the operator.
[0032] In actual use, the installation position and surrounding environment of the oil dipstick 20 may be different for transmissions of different models and specifications. The gripping portion 100, connecting part 200 and hook assembly 300 of the disassembly and assembly structure can be designed and adjusted according to actual conditions, and can adapt to the disassembly and assembly requirements of various transmission oil dipsticks 20, and has strong versatility.
[0033] In this solution, the hook assembly 300 includes a base plate, which is arranged at the end of the connecting member 200 away from the gripping portion 100; the curved hook 330 is symmetrically arranged at the bottom of the base plate; wherein, the base plate includes a horizontal end 320 and a curved end 310, the horizontal end 320 and the curved end 310 are an integrated structure, the horizontal end 320 is fixed to the connecting member 200, and the two curved hooks 330 are both installed on the horizontal end 320; wherein, the bending angle of the curved end 310 is greater than or equal to the bending angle of the curved hook 330. The hooks 330 are symmetrically arranged at the bottom of the base plate. When the dipstick 20 is hooked, the force acting on the dipstick 20 can be evenly distributed, avoiding shaking or sliding of the dipstick 20 due to uneven force, ensuring that the dipstick 20 remains stable during the disassembly and assembly process, and improving the reliability and safety of the operation; at the same time, compared with the single hook structure, the symmetrical hooks 330 have a larger contact area with the dipstick 20, and have stronger friction and gripping force, which can better fix the dipstick 20 and prevent the dipstick 20 from being separated from the hook assembly 300 when the gripping part 100 is rotated for disassembly and assembly, further enhancing the stability of the hook.
[0034] In addition, the design of the symmetrical hooks 330 makes it easier for the operator to find a suitable hooking position when hooking the oil dipstick; at the same time, since the hooks 330 are symmetrically distributed, the operator does not need to spend too much time adjusting the hooking angle, and only needs to put the two hooks 330 on the oil dipstick 20 to complete the hooking, which greatly shortens the operation time and improves work efficiency; when removing the oil dipstick 20, the structure of the symmetrical hooks 330 also makes the operation more convenient. The operator only needs to rotate the grip 100 in the opposite direction, and the symmetrical hooks 330 can evenly apply pulling force to smoothly pull the oil dipstick 20 out of the transmission, avoiding the jamming or jamming phenomenon that may be caused by the single hook structure.
[0035] Since the shape and size of the transmission oil dipstick 20 may vary depending on different vehicle models and transmission models, the design of the symmetrical hook 330 has certain flexibility and versatility, and can adapt to oil dipsticks 20 of different shapes and sizes. No matter whether the oil dipstick 20 is round, square or other special shapes, as long as its size is within the hookable range of the hook 330, it can be stably hooked by the hook assembly 300.
[0036] Furthermore, the horizontal end 320 and the curved end 310 are integrally formed, eliminating gaps and potential stress concentration points between them. This allows for more uniform stress distribution across the entire base plate, thereby enhancing the structural strength and stability of the entire hook assembly 300 and reducing the risk of failure due to loose or broken components. The angle of the curved end 310 is greater than or equal to that of the hook 330, allowing the curved end 310 to provide guidance when hooking the oil dipstick 20. When the operator brings the hook assembly 300 close to the oil dipstick 20, the curved end 310 provides preliminary guidance, allowing the dipstick 20 to more easily enter the hooking range of the hook 330, thereby improving hooking accuracy and efficiency.
[0037] Furthermore, the curved end 310 and the connector 200 are axially perpendicular, and the connector 200 is welded to the middle of the horizontal end 320, allowing the hook assembly 300 to reach a balanced state when subjected to force. When force is applied to the oil dipstick 20 through the grip 100 to disassemble or assemble the oil dipstick, the force is transmitted along the connector 200 to the horizontal end 320. Since the connector 200 is in the middle, the force can be evenly distributed to both sides of the horizontal end 320, avoiding local stress concentration caused by uneven force. For example, when disassembling the oil dipstick 20, if the welding position of the connector 200 is offset, one side of the horizontal end 320 may be subjected to excessive tension, which can easily cause deformation or damage to that side. However, welding in the middle can effectively avoid this situation, improving the overall load-bearing capacity of the hook assembly 300.
[0038] From the perspective of torque, the design of the middle welding makes the transmission of torque more reasonable. When the grip 100 is rotated, the connecting part 200 acts as a force transmission rod, and its welding position with the horizontal end 320 determines the size of the moment arm. The middle welding can make the moment arm relatively stable, ensuring that the size and direction of the torque acting on the oil dipstick 20 are in line with expectations, thereby more accurately controlling the disassembly and assembly process of the oil dipstick 20 and reducing operational difficulties or component damage caused by unreasonable torque.
[0039] Furthermore, during assembly and disassembly of the oil dipstick 20, the hook assembly 300 is subject to various external forces, such as vibration and inertia. The central weld design strengthens the connection between the connector 200 and the horizontal end 320, reduces horizontal sway and deviation of the connector 200, ensures the stable posture of the hook assembly 300, and improves operational reliability and safety. When the operator rotates the grip 100, the hook assembly 300 is subject to torsional forces. The central weld structure better resists these torsional forces, allowing the connector 200 and the horizontal end 320 to withstand torsional forces as a whole. This prevents relative rotation caused by a loose connection between the connector 200 and the horizontal end 320, improves the torsional resistance of the hook assembly 300, and extends its service life.
[0040] Through the above-mentioned welding fixation, no matter what operating posture the operator adopts, the hook assembly 300 welded in the middle can maintain good operating performance, and the position and angle of the gripping part 100 can be flexibly adjusted according to actual conditions without affecting the convenience of operation due to improper position of the connecting part 200.
[0041] In this solution, the connector 200 is a tubular or rod-shaped structure. In one embodiment, the connector 200 is tubular. The tubular connector 200 has good rigidity while ensuring a certain strength, and can maintain a stable shape when subjected to force. Moreover, the tubular structure can balance strength and weight by reasonably designing the wall thickness. On the premise of meeting the use requirements, the overall weight of the hook assembly 300 is reduced, making it easier for operators to carry and use.
[0042] In another embodiment, the connecting member 200 is a rod-shaped structure. The rod-shaped connecting member 200 generally has high tensile, compressive and bending strengths. When disassembling and assembling the transmission oil dipstick 20, a certain force needs to be applied to pull or push the oil dipstick 20. The rod-shaped connecting member 200 can withstand these forces without obvious deformation or damage, thereby ensuring the stability and reliability of the hook assembly 300.
[0043] In this embodiment, the bending direction of the curved end 310 is opposite to that of the hook 330. When the curved end 310 and the hook 330 bend in opposite directions, they create a mutually restraining force when hooking the dipstick 20. Using a common lever analogy, the curvature of the curved end 310 provides a reverse support point for the hook 330, effectively distributing and balancing the reaction force exerted by the dipstick 20 when the hook 330 is hooked. For example, when removing the dipstick 20, the dipstick 20 may attempt to break free from the hook 330. However, the reverse curvature of the curved end 310 can offset some of this reaction force, allowing the hook 330 to more securely engage the dipstick 20 and reducing the risk of the dipstick 20 slipping.
[0044] When disassembling and assembling the oil dipstick 20, the operator needs to rotate the gripping portion 100 to drive the connecting piece 200, the bent end 310 and the hook 330 to move. The design of the bent end 310 and the hook 330 with opposite bending directions can increase the stability of the entire hook assembly 300 and reduce shaking during operation.
[0045] The grip portion 100 has a tubular, rod-shaped, ring-shaped, or triangular structure. The smooth surface of the tubular grip portion 100 provides a comfortable grip, reducing friction and pressure on the hand, making it particularly suitable for prolonged operation. For example, in a car repair shop, where maintenance personnel may frequently remove and install the transmission fluid dipstick 20, the tubular grip portion 100 can reduce hand fatigue. The rod-shaped grip portion 100 is relatively simple in structure and compact, making it easy to carry and store.
[0046] The annular grip 100 allows the operator to adopt a variety of gripping methods, such as one-handed and two-handed. The operator can choose the appropriate gripping method based on actual conditions and personal preferences, improving operational comfort and flexibility. The annular structure evenly distributes force across the entire ring when subjected to stress, reducing the risk of localized stress concentration. During assembly and disassembly of the oil dipstick 20, the annular grip 100 is unlikely to break or deform, even when subjected to significant force. Furthermore, auxiliary devices such as anti-slip sleeves and rubber pads can be added to the annular grip 100 to improve grip stability and comfort, while also providing a certain degree of cushioning to reduce impact on the hand.
[0047] The triangular structure has three support points, making it more stable when the operator holds it and less likely to slip. This ensures a secure grip even with sweaty or oily hands during operation. Furthermore, the triangle provides stability, ensuring that the triangular grip 100 maintains structural stability when subjected to force, preventing it from shaking or deforming. This ensures accurate force transmission when installing or removing the oil dipstick, improving operational precision and efficiency. Furthermore, the triangular structure effectively disperses impact forces, making it less susceptible to damage from external impacts. At a maintenance site, tools can be accidentally dropped or impacted, and the triangular grip improves their resistance to damage.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit its scope of protection. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art may still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the scope of protection of the pending claims of the invention.
