DETAILED DESCRIPTION
[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0028] like Figures 1 to 5 As shown, a vehicle combination switch handle includes: a handle body, the handle body includes a handle frame 100, a first shell 200, a first knob 300 and a second shell 400, the first shell 200, the first knob 300 and the second shell 400 are all sleeved on the handle frame 100, the first shell 200 and the second shell 400 are both fixedly connected to the handle frame 100, the first knob 300 is rotatably connected to the handle frame 100, one end of the first knob 300 is connected to the first shell 200, and the second shell 400 is connected to the other end of the first knob 300, a first sealing ring 210 is provided at the joint between the first knob 300 and the first shell 200, and a second sealing ring 410 is provided at the joint between the first knob 300 and the second shell 400.
[0029] The characteristics of the vehicle combination switch handle are: it can meet the high sealing requirements of waterproof and dustproof and take into account the convenience of production. The handle body is the basic part of the entire combination switch handle. The handle body is designed as a stackable assembly structure. After stacking and assembling, the components are sealed by sealing rings, thereby meeting the sealing requirements on the basis of reducing the difficulty of assembly. The handle skeleton 100 serves as the core supporting structure. The handle skeleton 100 provides strength and stability. All other components are directly or indirectly mounted on this handle skeleton 100. The first shell 200 and the second shell 400 cover the outside of the handle skeleton 100, mainly playing the role of protecting the internal mechanical structure. The first shell 200 and the second shell 400 are fixedly connected to the handle skeleton 100. The first knob 300 is an operating component that can rotate relative to the handle skeleton 100. By rotating the first knob 300, the user can select different functions or adjust settings. The first knob 300 is located between the first shell 200 and the second shell 400, and the two ends of the first knob 300 are respectively connected to the first shell 200 and the second shell 400, and the first sealing ring 210 and the second sealing ring 410 are respectively provided at the joints between the first knob 300 and the first shell 200 and the joints between the first knob 300 and the second shell 400. The main function of these sealing rings is to prevent dust, water vapor, etc. from entering the interior, thereby extending the service life of the product and maintaining good operating performance.
[0030] During assembly, the first shell 200 is inserted from one end of the handle frame 100 until it is fully in place, ensuring that the first shell 200 is firmly fixed on the handle frame 100, and the first sealing ring 210 is inserted into the outer end of the first shell 200, and the first knob 300 is inserted from the same end of the handle frame 100 until one end thereof docks with the outer end of the first shell 200. One end of the first knob 300 should be in close contact with the first sealing ring 210 to ensure a good sealing effect, and the second sealing ring 410 is inserted into the other end of the first knob 300, and the second shell 400 is inserted from the same end of the handle frame 100 until it docks with the other end of the first knob 300. The end of the second shell 400 presses the second sealing ring 410 to ensure a seal with the first knob 300.
[0031] This stacked assembly combination switch handle design has many advantages. It does not require very precise assembly. It can be assembled by stacking each component on the handle frame 100 in sequence. Since the requirement for assembly accuracy is avoided, the difficulty of assembly is greatly reduced. This modular stacking method can make the components more closely connected, and the dimensional accuracy is better controlled, reducing potential water seepage points and dust ingress points.
[0032] A combination switch handle capable of being stacked and assembled is provided, wherein a first shell 200, a first knob 300 and a second shell 400 are sequentially sleeved on a handle frame 100, and then the first shell 200 and the second shell 400 are respectively docked with two ends of the first knob 300 and sealing rings are provided at the docking positions to greatly improve the waterproof and dustproof sealing, thereby greatly reducing the difficulty of assembly and improving the assembly efficiency.
[0033] like Figures 1 to 4 As shown, on the basis of the above embodiment, the handle body also includes a second knob 500 and a third shell 600, the second knob 500 and the third shell 600 are both mounted on the handle frame 100, the third shell 600 is fixedly connected to the handle frame 100, the second knob 500 is rotatably connected to the handle frame 100, one end of the second knob 500 is docked with the second shell 400, the third shell 600 is docked with the other end of the second knob 500, a third sealing ring 420 is provided at the docking point of the second knob 500 and the second shell 400, and a fourth sealing ring 610 is provided at the docking point of the second knob 500 and the third shell 600.
[0034] A second knob 500 and a third shell 600 are added on the basis of the second shell 400. The second knob 500 is a rotatable operating component similar to the first knob 300. The second knob 500 is located between the second shell 400 and the third shell 600. The third shell 600 is located at the outermost end of the handle body. The second knob 500 and the second shell 400 are sealed by a third sealing ring 420, and the second knob 500 and the third shell 600 are sealed by a fourth sealing ring 610.
[0035] During assembly, first install the first shell 200, the first knob 300 and the second shell 400, then insert the third sealing ring 420 into the outer end of the second shell 400, and then insert the second knob 500, the fourth sealing ring 610 and the third shell into the handle frame 100 in sequence.
[0036] By adding the second knob 500, the handle can provide more control options to meet more complex or diverse operating requirements. The connection method of the second knob 500 is basically the same as that of the first knob 300, which is also very convenient during assembly.
[0037] like Figure 1 , Figure 4 , Figure 5 As shown, based on the above embodiment, the first shell 200 , the first knob 300 , the second shell 400 , the second knob 500 and the third shell 600 are stacked in sequence along the handle frame 100 .
[0038] The stacking design allows components to be assembled layer by layer in sequence, simplifying the assembly process. By setting a sealing ring at the joint between each knob and the housing, a multiple sealing structure is formed to effectively prevent moisture and dust from entering the interior. The stacking setting allows components to be assembled layer by layer in sequence, and the dimensional accuracy of each layer can be controlled individually, especially during the assembly process, the accumulated error can be gradually corrected to ensure the dimensional accuracy of the final product.
[0039] like Figure 1 , Figure 4 , Figure 5 As shown, on the basis of the above embodiment, the outer diameter of the first knob 300 is larger than the outer diameters of the first shell 200 and the second shell 400, and both ends of the first knob 300 are set as first stepped holes 310, and the end of the first shell 200 and one end of the second shell 400 are respectively connected to the first stepped holes 310 at both ends of the first knob 300.
[0040] The outer diameter of the first knob 300 is larger than the outer diameter of the first housing 200 and the second housing 400, which means that the first knob 300 will protrude from the housing, making it easier for the user to operate. Both ends of the first knob 300 are configured as stepped hole structures. The end of the first housing 200 is designed to be docked with the stepped hole at one end of the first knob 300, and one end portion of the second housing 400 is designed to be docked with the stepped hole at the other end of the first knob 300.
[0041] The design of the stepped hole can provide a step so that the ends of the first housing 200 and the second housing 400 can be embedded and fit tightly, greatly improving the assembly accuracy. The stepped hole provides additional contact area, enhances the stability between components, and the stepped hole design combined with the sealing ring provides a more effective seal to prevent moisture and dust from entering the interior.
[0042] Based on the above embodiment, the outer diameter of the second knob 500 is larger than the outer diameters of the second shell 400 and the third shell 600, and both ends of the second knob 500 are set as second stepped holes 510, and the other end of the second shell 400 and the end of the third shell 600 are respectively connected to the second stepped holes 510 at both ends of the second knob 500.
[0043] The outer diameter of the second knob 500 is greater than the outer diameters of the second housing 400 and the third housing 600, which means that the second knob 500 will protrude from the housing, making it easier for the user to operate. Both ends of the second knob 500 are configured as stepped hole structures. The end of the second housing 400 is designed to be docked with the stepped hole at one end of the second knob 500, and one end portion of the third housing 600 is designed to be docked with the stepped hole at the other end of the first knob 300.
[0044] On the basis of the above embodiment, the first sealing ring 210 is sleeved on the end of the first shell 200 and is located in a first stepped hole 310, the second sealing ring 410 is sleeved on one end of the second shell 400 and is located in another first stepped hole 310, the third sealing ring 420 is sleeved on the other end of the second shell 400 and is located in a second stepped hole 510, and the fourth sealing ring 610 is sleeved on the end of the third shell 600 and is located in another second stepped hole 510.
[0045] By arranging sealing rings at each joint, a multi-layer sealing structure is formed, which significantly improves the waterproof and dustproof performance. Each sealing ring is located in the stepped hole to ensure good compression and sealing effects.
[0046] On the basis of the above-mentioned implementation, the first sealing ring 210 , the second sealing ring 410 , the third sealing ring 420 and the fourth sealing ring 610 have the same structure and are all configured as L-shaped sealing rings.
[0047] like Figures 1 to 4As shown, based on the above embodiment, a circuit board 700 is arranged between the second knob 500 and the third housing 600, and the second knob 500 is provided with a conductive contact 520, which is circumferentially fixedly connected to the circuit board 700 and contacts the circuit board 700.
[0048] A conductive contact 520 is provided on the second knob 500, and an elastic member is provided between the second knob 500 and the conductive contact 520. The elastic member applies an elastic force along the axial direction of the handle frame 100 to the conductive contact 520, and the elastic force pushes the conductive contact 520 to contact the circuit board 700. When the second knob 500 rotates, the conductive contact 520 is driven to rotate, thereby connecting or disconnecting the contacts on the circuit board 700.
[0049] It should also be noted here that the control principle of the first knob 300 is the same as the control principle of the second knob 500 .
[0050] On the basis of the above embodiment, the handle body further includes a button 800 , which is mounted on the third housing 600 , and a conductive rubber 810 is connected to the end of the button 800 , which is disposed on the circuit board 700 .
[0051] During assembly, the conductive rubber 810 is placed on the circuit board 700 , ensuring that the conductive rubber 810 is aligned with the contacts on the circuit board 700 , and the button 800 is installed in the third housing 600 , with the end of the button 800 in contact with the conductive rubber 810 .
[0052] like Figures 1 to 5 As shown, based on the above embodiment, a vehicle includes a vehicle combination switch handle.
[0053] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0054] In addition, in the present invention, the descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
[0055] In the present invention, unless otherwise clearly stipulated and limited, the terms "connected", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly limited.
[0056] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
