Description

Technical Field

[0001] The present application relates to the technical field of vehicle power distribution, and in particular to a starter wiring device and an automobile power distribution system. Background Art

[0002] At present, in the field of power distribution of existing commercial vehicles, the power-related components mainly include generators, starters, batteries, bus switches, power cords and other components. Due to the different properties of the power supply or the source of the power supply, the wiring method or the power distribution principle is often different, which is reflected in the following two aspects: On the one hand, the wiring method of the battery, starter, and generator adopts the traditional wiring method, which is often the battery-bus switch-starter as a starting circuit, and the generator-bus switch-battery as a charging circuit. This not only brings the adverse effect of rising costs, but also brings a significant increase in the design workload. On the other hand, there are often multiple power line terminals connected to the same terminal. For some parts, the situation where two terminals are connected to the same terminal at the same time can be avoided as much as possible by adding terminals, but this often leads to an increase in cost and an increase in the size of the parts, which runs counter to the current trend of lightweighting and cost reduction. For starters and bus switches, the current practice is generally to achieve common terminal access / power supply by directly superimposing two terminals.

[0003] However, the terminal is generally a flat metal ring with a wire connected to one end, and the overall shape is similar to a spatula. When the terminal is taken / powered, the wires of the two terminals will interfere with each other. If the two wires partially interfere with each other due to factors such as worker quality, vibration deviation, etc., that is, one wire is partially or completely placed on the other, this will cause one terminal of the two flat terminals to be tilted relative to the other terminal. Especially after the worker sets the terminals of the two wires on the terminal column, he needs to let go to take the tightened parts. At this time, under the gravity and vibration of the factory environment, it is very easy for the two wires to sag and cause the two wires to interfere with each other. At this time, the two terminals are not in a flat state. If the worker does not pay attention to observation and adjustment, it is very easy to tighten them directly with a tightening tool in a state that is not completely flat. On the surface, the terminals seem to be flat and tightened, but in fact, the terminals and the gaskets or nuts are not completely flat, which can easily increase the contact resistance. In some extreme cases, it is easy to cause fires. In severe cases, it may even burn the vehicle, posing a great hidden danger to the reliability and safety of the entire vehicle. Summary of the invention

[0004] Aiming at the defects existing in the prior art, the purpose of the present application is to provide a starter wiring device and an automotive power distribution system, so as to avoid interference between the terminal blocks, make the terminal blocks lie flat naturally during the installation process, improve the safety of connecting two terminal blocks to one terminal post, and thus realize a more efficient power line layout.

[0005] To achieve the above object, on the one hand, the technical solution adopted is:

[0006] The present application provides a starter wiring device, including:

[0007] A terminal post for connecting to the starter,

[0008] Terminal blocks for connecting wires and the terminal post, with at least two, all sleeved on the terminal post;

[0009] A dislocation device for staggering each terminal block by a preset angle, which is connected to at least two terminal blocks.

[0010] In a more preferred improvement, the dislocation device is a spacer gasket, and at least two pairs of partition posts for staggering the terminal blocks by a preset angle are arranged on the spacer gasket.

[0011] In a more preferred improvement, the partition posts are arranged on the circumferential edge of the spacer gasket, and each partition post includes a blocking block respectively pointing to both sides of the plane where the spacer gasket is located;

[0012] A chamfer for helping the terminal block to be clamped between two adjacent blocking blocks of a pair of partition posts is arranged on the blocking block.

[0013] In a more preferred improvement, the terminal post includes:

[0014] The column body;

[0015] A limiting boss, which is arranged on the column body;

[0016] A limiting groove for accommodating the limiting boss is formed in the terminal block and / or the dislocation device.

[0017] In a more preferred improvement, the column body includes a fastening section and an installation section for connecting to the starter;

[0018] The starter wiring device further includes:

[0019] A first fastener for fixedly connecting to the fastening section, and when the first fastener is connected to the fastening section, the end face of the first fastener fits with the spacer gasket.

[0020] In a more preferred improvement, the fastening section and the first fastener are threadedly connected;

[0021] The first fastener further includes a panel for fitting the terminal block.

[0022] In a more preferred improvement, the column body further includes:

[0023] An installation ring is arranged at the junction of the installation section and the fastening section. The limiting boss is arranged on the outer surface of the installation ring, and the terminal block and the spacer are sleeved on the installation ring.

[0024] In a more preferred improvement, the first fastener includes a connecting part and a yielding part connected to each other. When the first fastener is connected to the fastening section, the connecting part is connected to the fastening section, the yielding part is sleeved outside the installation ring and abuts against one of the terminal blocks.

[0025] In a more preferred improvement, there is a clearance fit between the terminal block, the dislocation device and the installation ring, and the fitting degree range is the first range.

[0026] The present application also provides an automotive power distribution system, including a generator, a starter and a storage battery, and comprising:

[0027] The wiring end of the starter is provided with the starter wiring device as described above, and an opening and closing circuit for controlling the opening and closing of the starter is arranged in the starter;

[0028] The output end circuit of the generator is electrically connected to one of the terminal blocks in the starter wiring device, and the other terminal block in the starter wiring device is connected to the bus switch, and the bus switch is connected to the storage battery.

[0029] The beneficial effects brought by the technical solution provided by the present application include:

[0030] For the starter wiring device of the present application, when multiple terminal blocks need to be connected to the wiring terminal column on the starter, the dislocation device is used to forcibly stagger adjacent two terminal blocks by a certain angle and fix them. In this way, even if it rotates during the installation process, multiple wires must be staggered by a certain angle from each other, so that interference between two wires will definitely not occur. In this way, when tightening, the metal rings of adjacent terminal blocks must be able to be in a flat state. Workers can easily judge whether the wires connected to the two terminal blocks are completely staggered by relying on the feel of whether the terminal blocks are stuck into the dislocation device. In this way, the failure rate is greatly reduced, the production efficiency is improved, the technical requirements for workers are reduced, and the failure rate of power taking from the same column is effectively reduced.

[0031] On the other hand, a vehicle power distribution system provided by the present application, due to the provision of a special starter wiring device and an independent opening and closing circuit provided in the starter, enables some circuits to be combined for use, eliminating the need to connect each circuit to the bus switch. Based on the traditional power distribution method, the vehicle power distribution system is optimized. The connection of the generator to the bus switch circuit in the charging circuit is changed to the connection of the generator to the starter. The charging circuit changes from generator - bus switch - battery to generator - starter - bus switch - battery. Among them, the part from the starter to the battery borrows the original starting circuit from the starter to the battery, and the starting circuit remains unchanged. This design can not only significantly shorten the length of the power cord, thereby reducing costs, but also, since both the starter and the generator are arranged on the engine, the power cord from the generator to the starter can be modularly designed, greatly reducing the repetitive design, trial production, etc. of the power cord due to different vehicle models and different engine layout positions. At the same time, the power cord from the generator to the starter can be directly supplied with the engine assembly, reducing the assembly load of the vehicle assembly plant and improving the production rhythm and efficiency.

Detailed implementation manners

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] During the past vehicle installation process, each circuit was connected to the bus switch, and the bus switch controlled which circuits were connected. The key parts were the starter 7, generator 6 and battery 8 parts. Generally, the battery 8 drives the starter 7 to start, and then starts the entire vehicle. In specific cases, the generator 6 is also directly connected to the battery 8 to charge the battery 8. It can be seen that a large part of this set of circuits is a duplicate layout. For example, the part where the generator 6 is directly connected to the battery 8 is omitted, and the circuit is redirected to connect the battery 8 through the starter 7. This will inevitably require connecting the two terminals 2 to the terminal post 1 of the starter 7. However, during the trial production process, it was found that the product failure rate remained high. The most serious part was between the two terminals 2, where it was very easy to catch fire, making the idea of omitting the circuit completely unworkable.

[0046] To solve the above problems, the present application provides an embodiment of a starter wiring device, including a terminal post 1, a terminal 2 and a misalignment device.

[0047] Specifically, it can be seen in Figure 1 and Figure 7 , the misalignment device is located between the two terminals 2, and misaligns the terminals 2 by a preset angle. In this embodiment, the misaligned angle is at least 90°.

[0048] The structure of terminal 2 can be referred to Figure 2 and Figure 3 , including a flat metal ring and a columnar structure for connecting wires. In some embodiments, the columnar structure for connecting wires is embedded in the wires. In the normal process of leveling two terminals 2, the power lines should be staggered at a certain angle, and the sides of the metal rings of the two adjacent terminals 2 fit together. This is called leveling the terminals 2, and the side of the metal ring of one of the terminals 2 should also fit with the conductive component of the terminal column 1. At this time, the contact area is the largest and the contact resistance is the smallest.

[0049] The reason why the present embodiment provides a misalignment device with a staggered angle to solve the problem of fire at the wiring terminals 2 is that it is found in the production process that, in the general vehicle assembly process, the starter 7, the generator 6 and the battery 8 are installed before wiring. At this time, the vision of the installation workers is limited, and it is impossible to accurately judge whether the two wiring terminals 2 are flat. In particular, after the two pieces of wiring terminals 2 are set on the terminal column 1, the general workers have to loosen their hands to take the fastened parts. Under the influence of gravity, the vibration of the factory environment and the installation actions of other parts of the frame, the two wires are very likely to deviate to the same direction. For example, both wires sag. When fastening, due to the workers' vision and installation experience, they can only stagger a certain angle according to habit. During installation, the state of the wiring terminals 2 cannot be seen, and the feel does not change much. It is difficult to judge whether the two wiring terminals 2 are completely flat. They are often fastened in a non-flat state, resulting in too small a contact surface between the two adjacent wiring terminals 2. The contact surface between the metal rings of the wiring terminals 2 installed in this way is smaller than the conventional one. After power is turned on, it is very easy to cause a fire accident due to the increase in contact resistance, which is also the cause of the high failure rate. After the dislocation device is provided, workers can easily judge whether the wires connected to the two terminals 2 are completely staggered by feeling whether the terminals 2 are inserted into the dislocation device. This greatly reduces the failure rate, improves production efficiency, reduces the technical requirements for workers, and enables the above-mentioned idea of eliminating the circuit to be realized.

[0050] There are many alternatives for the misalignment device, such as using a mold to lock the position of the two wires, so that after all the terminals 2 are put on the terminal posts 1, the positions of the wires are adjusted and the mold is put into the position to lock the wires, so that the two wires are guaranteed to be staggered. However, this installation method is very troublesome.

[0051] In one preferred embodiment, the aforementioned offset device is set as a separation gasket 3, and the details can be seen in Figure 2 , Figure 4 and Figure 7 .

[0052] Specifically, the diameter of the spacer 3 is generally approximately equal to that of the terminal 2, so as to avoid interference with the housing of other parts of the starter 7. On the other hand, the spacer 3 is generally made of metal, such as copper, which also increases the thickness of the terminal 2 in disguise, thereby reducing the adverse effects caused by the need to cross some power lines due to the limitation of the construction location.

[0053] The separation pad 3 is also provided with separation columns 31, and there are at least two pairs of separation columns 31, generally four pairs, so that as long as each terminal 2 is inserted into the interval formed by different separation columns 31, a complete staggered effect can be achieved. Specifically, in this embodiment, there are two pairs of separation columns 31, which can be seen in FIG. Figure 4 and Figure 7 , which constitutes three installation positions, namely Figure 7 In the direction shown, between the upper left and the upper right, between the upper left and the lower left, between the upper right and the lower right, this arrangement is to give one of the terminal blocks 2 enough room for movement, as can be seen in FIG. Figure 7 The upward terminal 2 is almost fixed by the two partition blocks 31, and there is an angle of at least 90° between the left terminal 2 and the upward terminal 2, and there is also a 30° movable space, that is, the angle between the two terminals 2 ranges from 90° to 120°.

[0054] In some cases, due to the obstruction of vision at the construction site, it is difficult for the installers to see the specific direction of the partition gasket 3, and the partition gasket 3 itself does not have a limiting structure, resulting in the terminal 2 easily rotating with the installation action when the installers install a new terminal 2 on the partition gasket 3, making it difficult for the terminal 2 to be inserted between the partition columns 31, making the installation more inconvenient.

[0055] Therefore, in some more preferred embodiments, the partitioning column 31 is arranged at the circumferential edge of the partitioning gasket 3, and can be seen in Figure 4 Each separation stopper 31 includes two stoppers 311 pointing to both sides of the plane where the separation gasket 3 is located. The two stoppers 311 are used to clamp the connection terminal 2. In some cases, the connection terminal 2 is round. In this case, the stopper 311 clamps the connection position between the connection terminal 2 and the wire. At the same time, in order to facilitate the insertion of the connection terminal 2, the adjacent stoppers 311 in a pair of separation stoppers 31 are provided with chamfers 312. For details, please refer to Figure 4 and Figure 7 .by Figure 4The directions shown are described. On the upper left and lower left of the two stoppers 311 on the side facing the observer, two opposite chamfers 312 are provided, so that the terminal 2 can easily slide in, and the direction is to the left. On the upper left and upper right of the two stoppers 311 on the side facing away from the observer, two opposite chamfers 312 are provided, so that during installation, it can easily slide into the already installed terminal 2. In this way, one wire is upward and one wire is to the left, and the two are at least 90° apart and completely staggered. And the installer can easily judge whether they are staggered only by feeling and the orientation of the power cord, and at the same time, it is not necessary for the installer to hold the two wires all the time, reducing the installation difficulty.

[0056] In other cases, during the installation process, after the worker sleeved the terminal 2 on the terminal post 1 and then installed the misalignment device, the already installed terminal 2 was not limited in a certain way and was very easy to rotate with the installation action, resulting in the misalignment device being difficult to combine well with the already installed terminal 2.

[0057] Therefore, in some embodiments, as Figure 2 and Figure 5 shown. The above-mentioned terminal post 1 includes a column body 11 and a limiting boss 12. The limiting boss 12 is formed by upward partial protrusion. And referring to Figure 3 and Figure 4 , a limiting groove 4 for accommodating the limiting boss 12 is provided in the terminal 2 and the misalignment device. Generally, the size is slightly larger than the limiting boss 12, so that the terminal 2 and the misalignment device can be easily sleeved on the terminal post 1 and the rotation of the terminal 2 is prevented, greatly improving the installation efficiency. In some embodiments, referring to Figure 7 , in order to facilitate the rotation of one of the wires according to the installation position requirements and avoid being restricted by the limiting boss 12, a thicker terminal 2 and misalignment device will be selected, so that the second installed terminal 2 is only restricted by the misalignment device and not by the limiting boss 12, so that the second installed terminal 2 has enough rotation space.

[0058] And in order to facilitate maintenance and replacement, the component for fastening the terminal 2 is preferably detachable and adjustable in pressure. Therefore, in one preferred embodiment, the above-mentioned column body 11 includes an installation section 112 and a fastening section 111. The installation section 112 of the column body 11 is mainly for facilitating the connection and installation with the starter 7. Specifically, referring to Figure 2 , there are also workpieces such as nuts for connection and positioning between the column body 11 and the starter 7. The installation section 112 is provided to facilitate the connection with these parts without interference. Its surface is not necessarily completely smooth, as long as it does not interfere with these connection parts. The fastening section 111 is mainly used to connect the first fastener 5 and at the same time make the first fastener 5 fit with the spacer 3.

[0059] There are many ways to fasten the terminal 2 to the terminal post 1. For example, a sleeve with an inner diameter slightly smaller than the terminal post 1 is put over the terminal post 1, and in this way, the sleeve is clamped on the post by interference fit, and the other end of the sleeve abuts against the terminal 2 to flatten it.

[0060] In one preferred embodiment, there is a threaded connection between the fastening section 111 and the first fastener 5. Referring to Figure 2 and Figure 6 , the above-mentioned first fastener 5 is also provided with a facing plate 53. The main function of the facing plate 53 is to increase the force-bearing area when abutting against the terminal 2, prevent scratching and crushing the surface of the terminal 2.

[0061] In some cases, the limiting boss 12 is directly provided on the column body 11. In order to achieve a tight connection, the dimensions of the limiting boss 12, the terminal 2 and the corresponding limiting groove 4 on the dislocation device should be as matched as possible. This results in the inner diameter of the terminal 2 being close to the outer diameter of the column body 11. And the fastening section 111 needs to be connected to the first fastener 5, and there are also many corresponding adapted structures, such as threads. This leads to the need for the terminal 2 to reserve a certain gap for these structures, which will cause the terminal 2 to be eccentric and reduce the contact area between the terminal 2 and the terminal post 1.

[0062] Therefore, in some preferred embodiments, as shown in Figure 2 and Figure 5 , the above-mentioned column body 11 further includes an installation ring 113. The installation ring 113 is located at the junction of the installation section 112 and the fastening section 111. At this time, the limiting boss 12 is located on the outer surface of the installation ring 113. At least one terminal 2 and the dislocation device need to be sleeved on the installation ring 113. In this way, the inner diameter of the terminal 2 can be made larger than the outer diameter of the fastening section 111 without affecting the concentricity between the terminal 2 and the terminal post 1. In general embodiments, in order to facilitate the subsequent installed terminal 2 to also maintain concentricity with the terminal post 1, for example, in the case shown in Figure 7 , it is required that the sum of the thicknesses of the terminal 2 and the dislocation device does not exceed the axial length of the installation ring 113, so that the third terminal 2 is also installed on the installation ring 113.

[0063] In some cases, in order to ensure the fastening of the connection of the terminal 2, the installation ring 113 is lengthened so that the subsequently connected terminal 2 is also tightly sleeved on the installation ring 113. This avoids the sliding between the two terminals 2 due to various situations such as vehicle vibration.

[0064] In order to deal with this situation, in some more preferred embodiments, the first fastener 5 includes a connecting portion 51 and a yielding portion 52 that are connected to each other. The connecting portion 51 is used to connect with the fastening section 111. In this embodiment, the connecting portion 51 and the fastening section 111 are threadedly connected. In other embodiments, other types of connections may also be used. The yielding portion 52 is sleeved outside the mounting ring 113, and abuts against the terminal 2 as the first fastener 5 is gradually advanced. The depth of the yielding portion 52 and the total thickness of the multiple terminal 2 and the offset device need to exceed the total length of the mounting ring 113 to prevent the terminal 2 from not being sleeved on the mounting ring 113, resulting in insufficient concentricity, and to prevent the contact area between the terminal 2 and the terminal column 1 from being too small.

[0065] In some more preferred embodiments, the connection terminals 2, the dislocation device and the mounting ring 113 are all clearance-fitted, and the fit range is the first range. In this embodiment, the fit is 0-0.1 mm, which is convenient for installation and helps to maintain coaxiality as much as possible.

[0066] In the existing commercial vehicle power distribution field, the power supply-related components mainly include generator 6, starter 7, battery 8, bus switch, power cord and other components. Due to the different power properties or power sources, the wiring method or distribution principle is often different, which is reflected in the following two aspects: On the one hand, the wiring method of battery 8, starter 7 and generator 6 adopts the traditional wiring method, which is often battery 8-bus switch-starter 7 is a starting circuit, and generator 6-bus switch-battery 8 is a charging circuit, which not only brings the adverse effect of rising costs, but also brings a significant increase in design workload.

[0067] like Figure 8 As shown, the starting and charging circuit power line of a commercial vehicle generally includes four main components: a starter 7, a generator 6, a bus switch and a battery 8. The starter 7 and the generator 6 are components of the automobile engine, and also include three main lines: the bus switch to the battery 8, the starter 7 to the bus switch, and the generator 6 to the bus switch.

[0068] The generator 6 and the starter 7 are arranged on the engine of the car, and the battery 8 is arranged on the frame. Due to the different arrangements of the engine and the battery 8 on different models, there is a lot of repeated design work from the starter 7 to the bus switch and from the generator 6 to the bus switch, and there are overlapping parts between the two power lines, which wastes raw materials.

[0069] Therefore, on the basis of these issues, we can see Figure 8, this application also provides an embodiment of an automotive power distribution system. Since the generator 6 and the starter 7 are very close to each other, in this embodiment, one end of the output current of the generator 6 is directly electrically connected to the starter 7, and the aforementioned starter wiring device is provided on the terminal of the starter 7. In this embodiment, the starter wiring device is provided with two terminal connectors 2. The generator 6 is connected to one of the terminal connectors 2, and the other terminal connector 2 of the starter wiring device is connected to the bus switch, and the bus switch is connected to the battery 8.

[0070] Meanwhile, an opening and closing circuit is provided in the starter 7 to control whether the starter 7 is powered on and started. In this embodiment, the opening and closing circuit is controlled by the vehicle ECU.

[0071] When it is necessary for the generator 6 to charge the battery 8, the opening and closing circuit controls the disconnection of the electrical connection between the starter 7 and the terminal post 1, and it is no longer powered on and started, which is equivalent to the generator 6 directly supplying power to the battery 8. When it is necessary for the battery 8 to start the starter 7, the opening and closing circuit controls the starter 7 to be powered on and started at the same time. At this time, it is equivalent to the battery 8 directly supplying power to the starter 7.

[0072] In this embodiment, due to the provision of a special starter wiring device and an independent opening and closing circuit provided in the starter 7, some circuits can be combined for use, without connecting each circuit to the bus switch. Based on the traditional power distribution method, the vehicle power distribution system is optimized. The charging circuit where the generator 6 is connected to the bus switch circuit is changed to the generator 6 connected to the starter 7. The charging circuit changes from generator 6 - bus switch - battery 8 to generator 6 - starter 7 - bus switch - battery 8. The part from the starter 7 to the battery 8 borrows the original starting circuit from the starter 7 to the battery 8, and the starting circuit remains unchanged. This design can not only greatly shorten the length of the power supply line, thereby reducing costs, but also since both the starter 7 and the generator 6 are arranged on the engine, the power supply line from the generator 6 to the starter 7 can be modularly designed, greatly reducing the repetitive design, trial production, etc. of the power supply line due to different vehicle models and different engine arrangement positions. At the same time, the power supply line from the generator 6 to the starter 7 can be directly supplied with the engine assembly, reducing the assembly load of the vehicle assembly plant and improving the production tempo and efficiency.
