Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically a multifunctional automotive relay. Background Technology

[0002] Automotive relays play a crucial role in automotive circuits. They are "automatic switches" that use a small current to control a large current. Their main functions include automatic adjustment, safety protection, circuit switching, and switching. Common applications of automotive relay control include headlight control, motor control, door lock control, fan control, as well as some starter motors, horns, vacuum pumps, etc.

[0003] As a fundamental electronic component in vehicles, the versatility of automotive relays is crucial for customers. Due to the diversity of vehicle functions, such as headlights, horns, and fans, each function has specific requirements for the load current, voltage, and circuit design of the relay. For example, controlling high beams or low beams usually requires a double-pole single-throw relay, while controlling the horn or fan may only require a single-pole single-throw product. These different application requirements lead to the need for different models of relays, increasing the number of relay series models and also bringing different installation methods, which brings more workload to relay assembly and circuit design. In view of this, we provide a multi-functional automotive relay. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multifunctional automotive relay.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional automotive relay, comprising a housing, a coil frame fixedly connected to the bottom of the housing, and a set of lead pins fixedly connected to one side of the coil frame, an enameled wire wound around the center of the outer wall of the coil frame, and a yoke slidably connected to the bottom of the coil frame, an iron core penetrating through the center of the coil frame, and a positioning plastic part snapped onto one side of the bottom surface of the coil frame, a set of corresponding stationary springs fixedly connected to one side of the outer wall of the positioning plastic part, and a stationary contact riveted to the center of the top surface of the stationary springs, a dummy stationary spring fixedly connected to one side of the outer wall of the positioning plastic part, an armature fixedly connected to the outer wall of the top of the coil frame, and a moving spring assembly fixedly connected to the outer wall of the top of the armature, a plurality of moving springs simultaneously provided on one side of the bottom of the moving spring assembly, and a plurality of moving contacts simultaneously riveted to one side of the top surface of the moving spring assembly.

[0006] As mentioned above, the outer wall of the lead is provided with barbs on one side, and multiple winding grooves are opened on the outer wall of the lead at the same time. The enameled wire is wound around the center of the outer wall of the coil frame using a winding process.

[0007] As described above, the outer wall of one side of the yoke is connected through to the bottom of the coil frame, and the bottom of the outer wall of the yoke is slidably connected to the bottom of the coil frame. The center of the outer wall of the iron core passes through the center of the coil frame, and the bottom of the outer wall of the iron core extends to the center of the yoke.

[0008] As described above, a positioning rib is provided on one side of the bottom surface of the coil frame, and a positioning slot is provided on one side of the bottom of the positioning plastic part. The positioning plastic part is engaged and connected to one side of the outer wall of the coil frame through the positioning rib and the positioning slot.

[0009] As described above, the top surface of the moving spring assembly has a positioning hole at its center, and the top surface of the armature has multiple positioning bolts, which are nested inside the center of the positioning hole.

[0010] As described above, a plurality of movable spring protrusions are provided on one side of the outer wall of the yoke, and a plurality of protrusion holes are opened on one side of the outer wall of the movable spring assembly, and the plurality of movable spring protrusions are embedded inside the protrusion holes.

[0011] As mentioned above, a reinforcing rib is provided on one side of the outer wall of the dummy static spring, and multiple protrusions are provided on one side of the outer wall of the dummy static spring.

[0013] 1. In this utility model, the stationary and moving reeds on the same side can control one circuit, while the stationary and moving reed circuits on the other side can control another circuit. At this time, the relay realizes double-pole single-throw, that is, one moving reed controls two output stationary reeds.

[0014] Second, because the multiple output stationary reeds are all connected to the passive reed ends, the multiple stationary reeds are also in a conductive state. If the moving reed is not connected to the circuit, the moving reed assembly is equivalent to a wire inside the relay, which connects the multiple stationary reeds to each other. The conductive state between the multiple stationary reeds is used to realize the on / off state of the control circuit, thus realizing the function of single-pole single-throw.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-13 As shown, this utility model provides a technical solution: a multifunctional automotive relay, including a housing 1, a coil frame 2 fixedly connected to the bottom of the housing 1, and a set of lead pins 3 fixedly connected to one side of the coil frame 2, an enameled wire 4 wound around the center of the outer wall of the coil frame 2, and a yoke 5 slidably connected to the bottom of the coil frame 2, an iron core 6 penetrating through the center of the coil frame 2, a positioning plastic part 7 snapped onto one side of the bottom surface of the coil frame 2, a set of corresponding stationary springs 701 fixedly connected to one side of the outer wall of the positioning plastic part 7, a stationary contact 702 riveted to the center of the top surface of the stationary springs 701, a dummy stationary spring 703 fixedly connected to one side of the outer wall of the positioning plastic part 7, an armature 8 fixedly connected to the outer wall of the top of the coil frame 2, and a moving spring assembly 801 fixedly connected to the outer wall of the top of the armature 8, a plurality of moving springs 802 provided on one side of the bottom of the moving spring assembly 801, and a plurality of moving contacts 803 riveted to one side of the top surface of the moving spring assembly 801.

[0032] The stationary reed 701 and moving reed 802 on the same side can control one circuit, while the stationary reed 701 and moving reed 802 circuit on the other side can control another circuit. At this time, the relay realizes double-pole single-throw, that is, one moving reed 802 controls two output stationary reeds 701. Because multiple output stationary reeds 701 are connected to the moving reed 802, the multiple stationary reeds 701 are also in a conducting state. If the moving reed 802 is not connected to the circuit, then the moving reed assembly 801 inside the relay is equivalent to a wire, connecting the multiple stationary reeds 701 to each other. The conducting state between the multiple stationary reeds 701 is used to realize the on and off of the control circuit, thus realizing the function of single-pole single-throw.

[0033] like Figure 5 As shown, a barb 301 is provided on one side of the outer wall of the lead pin 3, and multiple winding grooves 302 are also provided on one side of the outer wall of the lead pin 3. The enameled wire 4 is wound around the center of the outer wall of the coil frame 2 using a winding process. The barb 301 added to the lead pin 3 can effectively prevent accidental detachment. At the same time, the winding grooves 302 with two sides crossing each other are used on one side of the lead pin 3, which can not only meet the requirements of winding and tying the head, but also avoid the problem of reduced strength caused by the material size being too small.

[0034] like Figure 6As shown, the outer wall of one side of the yoke 5 is connected to the bottom of the coil frame 2, and the bottom of the outer wall of the yoke 5 is slidably connected to the bottom of the coil frame 2. The center of the outer wall of the iron core 6 passes through the center of the coil frame 2, and the bottom of the outer wall of the iron core 6 extends to the center of the yoke 5. After inserting the iron core 6 into the center of the coil frame 2, the yoke 5 and the coil frame 2 can be effectively fixed.

[0035] like Figure 2 , Figure 9 and Figure 10 As shown, a positioning rib 201 is provided on one side of the bottom surface of the coil frame 2, and a positioning slot 704 is provided on one side of the bottom of the positioning plastic part 7. The positioning plastic part 7 is engaged with one side of the outer wall of the coil frame 2 through the positioning rib 201 and the positioning slot 704. The coil frame 2 is fixed to the outer wall of the positioning plastic part 7 by the positioning rib 201 at the bottom of the coil frame 2 being embedded in the positioning slot 704.

[0036] like Figure 11 and Figure 12 As shown, a positioning hole 804 is provided at the center of the top surface of the moving spring assembly 801, and multiple positioning bolts 805 are provided at the center of the top surface of the armature 8. The positioning bolts 805 are nested inside the center of the positioning hole 804, and the positioning bolts 805 are used to limit the horizontal position of the moving spring assembly 801.

[0037] like Figure 11 and Figure 12 As shown, a plurality of movable spring protrusions 501 are provided on one side of the outer wall of the yoke 5, and a plurality of protrusion holes 806 are provided on one side of the outer wall of the movable spring assembly 801. The plurality of movable spring protrusions 501 are embedded in the protrusion holes 806, and the movable spring assembly 801 is firmly fixed to the armature 8 and the outer wall of the yoke 5 by means of the movable spring protrusions 501 and the positioning bolts 805.

[0038] like Figure 13 As shown, a reinforcing rib 705 is provided on one side of the outer wall of the dummy spring 703, and multiple protrusions 706 are provided on one side of the outer wall of the dummy spring 703. The protrusions 706 on the outer wall of the dummy spring 703 are interference-fitted with the interior of the positioning plastic part 7, so that the dummy spring 703 can be inserted into the interior of the positioning plastic part 7 to achieve the anti-detachment function.

[0039] Working principle: When multiple leads 3 are not energized, multiple moving springs 802 and multiple stationary springs 701 will not conduct with each other. At the same time, if multiple leads 3 are energized, multiple moving springs 802 and multiple stationary springs 701 will be in a conducting state. This can realize two control states.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
