Description

Technical Field

[0001] The utility model relates to the technical field of automotive switches, and particularly to a structure of an automotive combination switch handle. Background Art

[0002] The windshield cleaning of an automobile is an essential function during the use of the automobile. During the use of the automobile, dust is inevitably accumulated on the windshield or it comes into contact with other types of dirt. At this time, it is necessary to clean the windshield. A clean windshield can ensure that the driver has a clear driving vision, help the driver accurately identify and judge obstacles ahead, reduce traffic risks caused by blurred vision, and improve driving safety. Among them, the spraying function provides clean water for cleaning the windshield, allowing the driver to spray water on the windshield at any time for cleaning. The spraying function of the automobile is controlled by a washing control module. Generally, two conductive sheets are arranged in the combination switch to be electrically connected or disconnected from the contact piece respectively. A contact point is arranged at each end of the two conductive sheets in contact with the contact piece to contact the contact piece, and at the same time, it is electrically connected to a nozzle located on the windshield through a wire to form a spraying circuit to control the on / off of the spraying function. After the switch is used for a period of time, due to the large current in the spraying circuit, the contact points in the circuit are easily damaged. When one of the contact points on the two conductive sheets is ablated and damaged, the spraying circuit will be disconnected, and the spraying switch cannot be used, resulting in low durability. Therefore, there is an urgent need for a structure of a combination switch that can still ensure the normal use of the spraying circuit after one or more contact points in the circuit are damaged. Summary of the Utility Model

[0003] One of the purposes of the utility model is to provide a structure of an automotive combination switch handle to solve the problem that the spraying circuit is easily disconnected and the durability of the spraying switch is poor after one or two contact points of the spraying electrical circuit in the prior art are damaged.

[0004] In order to achieve the above purpose, the technical solutions adopted by the utility model are as follows:

[0005] An automotive combination switch handle structure includes: a housing and a support shaft. The housing includes a first housing body and a second housing body. The first housing body and the second housing body are spliced with each other to form an accommodation cavity, and the support shaft is located in the accommodation cavity; a first conductive member, a second conductive member, and a third conductive member. The first conductive member is installed on the first housing body. The second conductive member and the third conductive member are arranged on the support shaft, and one ends of the second conductive member and the third conductive member are respectively electrically connected to vehicle-mounted electrical appliances. The other ends of the second conductive member and the third conductive member are configured to be able to abut against or disengage from the first conductive member to form a conduction loop or a disconnection loop; at least two conductive contacts capable of abutting against the first conductive member are respectively arranged at the other ends of the second conductive member and / or the third conductive member to ensure electrical connection when the second conductive member and the third conductive member abut against the first conductive member.

[0006] By the above technical means, in the present utility model, at least two conductive contacts capable of abutting against the first conductive member are respectively arranged at the other ends of the second conductive member and / or the third conductive member, and at least two conductive loops can be formed when the first conductive member approaches the second conductive member and the third conductive member. During the use of the combination switch, when one or two of the conductive contacts on the second conductive member and / or the third conductive member are ablated and damaged due to excessive use, the remaining conductive contacts can still maintain the normal use of the conductive loop, increasing the service life of the combination switch and reducing the maintenance frequency of the combination switch.

[0007] Furthermore, a notch is formed at the other end of the second conductive member and / or the third conductive member, and the top end of the notch forms the conductive contact.

[0008] By the above technical means, forming a notch at the other end of the second conductive member and / or the third conductive member can increase the number of conductive contacts without affecting other components, and the processing method is simple.

[0009] Furthermore, the first housing body and the second housing body are movably spliced with each other, and the first housing body can move along the length direction of the support shaft so that the first conductive member installed on the first housing body can approach or move away from the second conductive member and the third conductive member.

[0010] By the above technical means, through the movement of the first housing body, the abutting against or disengagement between the first conductive member and the second conductive member and the third conductive member can be adjusted, so as to realize the conduction or disconnection of the loop connection.

[0011] Further, a first mounting cylinder is sleeved on the support shaft, and the first housing is sleeved outside the first mounting cylinder and can move along the length direction of the first mounting cylinder.

[0012] By the above technical means, the first mounting cylinder provides precise guidance for the movement of the first housing, ensuring the stability of the first housing during movement.

[0013] Further, a limiting groove is formed on the outer side wall of the first mounting cylinder, and a limiting block is formed on the inner side wall of the first housing. The limiting block is located in the limiting groove to limit the displacement of the first housing moving on the first mounting cylinder.

[0014] By the above technical means, the limiting block is located in the limiting groove, and the mutual cooperation of the limiting block and the limiting groove can ensure that the first housing will not exceed the predetermined range when moving along the length direction of the first mounting cylinder, avoiding excessive movement of the first housing.

[0015] Further, a gear block is also sleeved on the support shaft. The gear block is located inside the first mounting cylinder, and the gear block is used for controlling connection with the vehicle-mounted electrical appliance to control the working mode of the vehicle-mounted electrical appliance.

[0016] By the above technical means, the design of the gear block enables the vehicle-mounted electrical appliance to have multiple working modes, improving the flexibility and functionality of the vehicle-mounted electrical appliance in different usage environments.

[0017] Further, an elastic member is arranged inside the first housing. One end of the elastic member abuts against one side of the bottom surface of the first housing, and the other end abuts against the first conductive member. The elastic member has a tendency to make the first conductive member approach the second conductive member and the third conductive member.

[0018] By the above technical means, when the first housing is operated to approach the second conductive member and the third conductive member, the elastic member enables the first conductive member to maintain stable contact with the second conductive member and the third conductive member, so as not to disconnect the contact and cause the circuit to break.

[0019] Further, a second mounting cylinder is formed on one side of the bottom surface of the first housing, and the elastic member is installed in the second mounting cylinder.

[0020] By the above technical means, the second mounting cylinder provides precise positioning for the installation of the elastic member, enabling the elastic member to be simply and quickly installed on the first housing by just putting one end of the elastic member into the second mounting cylinder and fixing it.

[0021] Furthermore, an end cap is provided at the bottom end of the first housing, and the end cap covers the other side of the bottom surface of the first housing.

[0022] By means of the above technical means, setting an end cap at the bottom end of the first housing can effectively prevent external impurities from entering the interior of the first housing, so as to ensure the effectiveness of the electrical connection between the first conductive member, the second conductive member, and the third conductive member.

[0023] Furthermore, a clamping block is formed on the end cap, and a clamping notch is formed on the first housing, and the clamping block can be clamped in the clamping notch.

[0024] By means of the above technical means, the mutual cooperation of the clamping block and the clamping notch can make the end cap stably clamped on the first housing, and such a connection method is simple and convenient and has strong connection stability.

[0025] The beneficial effects of the present utility model are as follows:

[0026] In the present utility model, at least two conductive contacts capable of abutting against the first conductive member are respectively provided at the other ends of the second conductive member and / or the third conductive member, and at least two conductive circuits can be formed when the first conductive member approaches the second conductive member and the third conductive member. During the use of the combination switch, when one or two of the conductive contacts on the second conductive member and / or the third conductive member are ablated and damaged due to excessive use, the remaining conductive contacts can still maintain the normal use of the conductive circuit, increasing the service life of the combination switch and reducing the maintenance frequency of the combination switch.

[0035] The following will describe the implementation manners of the present invention with reference to the accompanying drawings and preferred embodiments.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present utility model and not for limiting the protection scope of the present utility model. It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present invention, and thus only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation.

[0036] This embodiment provides a Figures 1 to 5 kind of automotive combination switch handle structure as shown in the figure, including: a housing and a support shaft 200. The housing includes a first housing 110 and a second housing 120. The first housing 110 and the second housing 120 are spliced with each other to form an accommodation cavity, and the support shaft 200 is located in the accommodation cavity; a first conductive member 300, a second conductive member 400 and a third conductive member 500. The first conductive member 300 is installed on the first housing 110. The second conductive member 400 and the third conductive member 500 are arranged on the support shaft 200, and one ends of the second conductive member 400 and the third conductive member 500 are respectively electrically connected to vehicle-mounted electrical appliances. The other ends of the second conductive member 400 and the third conductive member 500 are configured to be able to abut against or disengage from the first conductive member 300 to form a conduction loop or a disconnection loop; at least two conductive contacts capable of abutting against the first conductive member 300 are respectively arranged at the other ends of the second conductive member 400 and / or the third conductive member 500 to ensure electrical connection when the second conductive member 400 and the third conductive member 500 abut against the first conductive member 300.

[0037] When it is necessary to conduct the circuit inside the combination switch, the operating handle can be used to move the first conductive member 300 close to the second conductive member 400 and the third conductive member 500 so that they are in contact with each other. At this time, the on-vehicle electrical appliance enters the working state; when it is necessary to disconnect the circuit inside the combination switch, the operating handle can be used to move the first conductive member 300 away from the second conductive member 400 and the third conductive member 500 to release the contact.

[0038] In this embodiment, at least two conductive contacts capable of abutting against the first conductive member 300 are respectively arranged at the other ends of the second conductive member 400 and / or the third conductive member 500, so that at least two conductive circuits can be formed when the first conductive member 300 approaches the second conductive member 400 and the third conductive member 500. During the use of the combination switch, when one or more of the conductive contacts on the second conductive member 400 and / or the third conductive member 500 are ablated and damaged due to excessive use, the remaining conductive contacts can still maintain the normal use of the conductive circuit, increasing the service life of the combination switch and reducing the maintenance frequency of the combination switch.

[0039] As Figure 2 shown, in this embodiment, a notch 410 is formed at the other end of the second conductive member 400 and / or the third conductive member 500, and the top of the notch 410 forms a conductive contact. Forming the notch 410 at the other end of the second conductive member 400 and / or the third conductive member 500 can increase the number of conductive contacts without affecting other components, with a simple structure and convenient and fast processing; at the same time, forming the notch 410 at the other end of the second conductive member 400 and / or the third conductive member 500 is to cut off part of the material on the basis of the original structure, which can save a certain amount of material and has a certain economy.

[0040] Preferably, the shape of the notch 410 is V-shaped.

[0041] In other embodiments, the shape of the notch 410 can also be U-shaped.

[0042] It is worth mentioning that in this embodiment, at least two notches 410 can be formed at the other end of the second conductive member 400 and / or the third conductive member 500, so that at least three conductive contacts are formed at the other end of the second conductive member 400 and / or the third conductive member 500. When at least one of the conductive contacts on the second conductive member 400 and / or the third conductive member 500 is ablated and damaged, the normal use of the conductive circuit can still be maintained.

[0043] In other embodiments, the other end of the second conductive member 400 and / or the third conductive member 500 can also be convex to form a conductive contact.

[0044] In this embodiment, the first housing 110 and the second housing 120 are movably spliced with each other, and the first housing 110 can move along the length direction of the support shaft 200, so that the first conductive member 300 mounted on the first housing 110 can approach or move away from the second conductive member 400 and the third conductive member 500. By moving the first housing 110, the mutual abutment or disengagement between the first conductive member 300 and the second conductive member 400 and the third conductive member 500 can be adjusted, thereby realizing the conduction or disconnection of the loop connection.

[0045] As Figure 1 shown, in this embodiment, a first mounting cylinder 600 is sleeved on the support shaft 200, and the first housing 110 is sleeved outside the first mounting cylinder 600 and can move along the length direction of the first mounting cylinder 600. The first mounting cylinder 600 provides precise guidance for the movement of the first housing 110, ensuring the stability of the first housing 110 during the movement.

[0046] Preferably, the first mounting cylinder 600 is fixed on the support shaft 200.

[0047] As Figure 4 and Figure 5 shown, in this embodiment, a limiting groove 610 is formed on the outer side wall of the first mounting cylinder 600, and a limiting block 111 is formed on the inner side wall of the first housing 110. The limiting block 111 is located in the limiting groove 610 to limit the displacement of the first housing 110 moving on the first mounting cylinder 600. The limiting block 111 is located in the limiting groove 610, and the mutual cooperation between the limiting block 111 and the limiting groove 610 can ensure that the first housing 110 will not exceed the predetermined range when moving along the length direction of the first mounting cylinder 600, avoiding excessive movement of the first housing 110.

[0048] During the specific operation process, the limiting block 111 can move in the limiting groove 610. When the first housing 110 needs to move towards the second housing 120 direction, since the limiting block 111 can only move in the limiting groove 610, the first housing 110 will not be excessively displaced and cause the first housing 110 to fall off from the first mounting cylinder 600.

[0049] As Figure 1 shown, in this embodiment, a gear block 700 is also sleeved on the support shaft 200. The gear block 700 is located inside the first mounting cylinder 600. The gear block 700 is used for controlling connection with the vehicle-mounted electrical appliance to control the working mode of the vehicle-mounted electrical appliance. The design of the gear block 700 enables the vehicle-mounted electrical appliance to have multiple working modes, improving the flexibility and functionality of the vehicle-mounted electrical appliance in different usage environments.

[0050] Preferably, a base is further provided on the support shaft 200, and a contact piece is provided on the base. The gear block 700 can be in contact connection with the contact piece. When it is necessary to adjust the working mode of the vehicle-mounted electrical appliance, the contact piece and the gear block 700 are rotated relative to each other, and the working mode of the vehicle-mounted electrical appliance can be adjusted.

[0051] In this embodiment, an elastic member 130 is provided in the first housing 110. One end of the elastic member 130 abuts against one side of the bottom surface of the first housing 110, and the other end abuts against the first conductive member 300. The elastic member 130 has a tendency to make the first conductive member 300 approach the second conductive member 400 and the third conductive member 500. When the first housing 110 is operated to approach the second conductive member 400 and the third conductive member 500, there is a risk that the operating force is not in place. If the first conductive member 300 and the first housing 110 are set to be rigidly connected, when the user's operating force on the first housing 110 is not in place, the first conductive member 300 has a risk of poor contact with the second conductive member 400 and the third conductive member 500; an elastic member 130 is provided between the first conductive member 300 and the first housing 110, so that after the user operates the first housing 110 to move towards the second housing 120 to make the first conductive member 300 abut against the second conductive member 400 and the third conductive member 500, the elastic member 130 is compressed to have a tendency to make the first conductive member 300 approach the second conductive member 400 and the third conductive member 500, further enabling the first conductive member 300 to maintain stable contact with the second conductive member 400 and the third conductive member 500 and preventing the contact from being disconnected and the circuit from being broken.

[0052] Preferably, a reset member is further provided on the first housing 110 that can automatically disconnect the electrical connection between the first conductive member 300 and the second conductive member and the third conductive member 500.

[0053] When it is necessary to conduct the circuit loop, the user manually operates the first housing 110 to move along the length direction of the support shaft 200 towards the second housing 120, so that the first conductive member 300 can abut against the second conductive member 400 and the third conductive member 500, making the circuit loop in the combination switch conductive; when it is not necessary to conduct the circuit loop, the user releases the force on the first housing 110, and the reset member makes the first conductive member 300 and the second conductive member 400 and the third conductive member 500 move away from each other to release the abutment and disconnect the loop.

[0054] As Figure 4 shown, in this embodiment, a second mounting cylinder 113 is formed on one side of the bottom surface of the first housing 110, and the elastic member 130 is installed in the second mounting cylinder 113. The second mounting cylinder 113 provides precise positioning for the installation of the elastic member 130, so that when the elastic member 130 is installed on the first housing 110, only one end of the elastic member 130 needs to be placed in the second mounting cylinder 113 and fixed, and the installation is simple and fast.

[0055] AsFigure 1 and Figure 3 As shown in Figure 3 , in this embodiment, an end cover 140 is provided at the bottom end of the first housing 110, and the end cover 140 covers the other side of the bottom surface of the first housing 110. Setting the end cover 140 at the bottom end of the first housing 110 can effectively prevent external impurities from entering the interior of the first housing 110, so as to ensure the effectiveness of the electrical connection between the first conductive member 300, the second conductive member 400, and the third conductive member 500.

[0056] In this embodiment, a clamping block 141 is formed on the end cover 140, and a clamping opening 112 is formed on the first housing 110. The clamping block 141 can be clamped in the clamping opening 112. The mutual cooperation of the clamping block 141 and the clamping opening 112 can make the end cover 140 firmly clamped on the first housing 110. Such a connection method is simple and convenient and has strong connection stability. At the same time, the installation method of the clamping block 141 and the clamping opening 112 is convenient for disassembly and assembly, so that when the combination switch handle needs to be maintained or replaced, the end cover 140 can be quickly disassembled from the first housing 110.

[0057] In other embodiments, the end cover 140 can also be installed on the first housing 110 by means of screws and nuts.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
