Description

Technical Field

[0001] The utility model relates to the technical field of electronic throttles, in particular to an installation structure for an electronic throttle pedal electrical parameter acquisition device. Background Art

[0002] The electronic throttle uses a wiring harness (wire) instead of a cable or a pull rod, and installs a micro motor on the throttle side. The motor is used to drive the throttle opening, which is the so-called "wire driving". The wire replaces the original mechanical transmission mechanism. The electronic throttle is an electronic control device that transmits the signal of the depth and speed of the throttle pedal through a position sensor to realize the throttle function. This signal will be received and interpreted by the on-board microcomputer, and then a control command will be issued to require the throttle to open quickly or slowly to the angle it should open according to the command. This process is accurate and fast, and there will be no problem of mechanical wear. An oscilloscope or a multimeter will be used to collect the electrical parameters of the electronic throttle pedal. No matter what kind of collection equipment is used for parameter collection through "wire driving", it is necessary to connect and install the collection equipment and the electronic throttle through wires, and the installation structure of the collection equipment is the structural part used to connect and assemble the wires of the electronic throttle.

[0003] For example, the public document with application number 201920208959.2 discloses an electronic accelerator pedal electrical parameter acquisition device. The utility model solves the problem that the general electronic accelerator pedal electrical parameter acquisition requires an oscilloscope or a multimeter through the setting of acquisition equipment, quick connectors, information processing modules, voltage acquisition modules, alarm modules, display modules and button modules. Both methods are limited to detection and cannot save data. The numerical determination needs to rely on manual labor, which is prone to misreading or the data saving time is too long, causing the process to become a bottleneck process. The data acquisition device has the advantage of being able to quickly acquire, display and process parameters, and is worthy of promotion. However, the electrical parameter acquisition device of the electronic throttle pedal adopts quick connectors for assembly of the installation connection between the wire and the acquisition device. Although the single quick connector makes the installation quick and has a certain stability, during the parameter acquisition process, the acquisition device, the wire and the electronic throttle may be pulled by external forces. The single quick connector installation and connection method is difficult to cope with the instantaneous pulling force, which may cause the wire to loosen and the terminal head to loosen and fall off, thereby affecting the stability of the acquisition and the progress of the acquisition work.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an installation structure for an electronic throttle pedal electrical parameter acquisition device is proposed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, the installation structure of the electronic throttle pedal electrical parameter acquisition device includes an acquisition device body 1, a power switch 2 is arranged at the front left side of the surface of the acquisition device body 1, a sink 3 is opened at the rear left side of the surface of the acquisition device body 1, a plug-in mechanism 4 is arranged on the inner surface of the sink 3, a locking mechanism 41 is arranged on the surface of the plug-in mechanism 4, a terminal crystal head 5 is arranged on the left side of the plug-in mechanism 4, a wire 6 is fixedly installed at the left end of the terminal crystal head 5, and a card slot 7 is opened on the front and rear sides of the surface of the terminal crystal head 5.

[0022] By adopting the above technical solution, by clamping the wire 6 and positioning the terminal crystal plug 5, the installation connection between the wire 6 and the terminal crystal plug 5 and the acquisition device body 1 is made extremely stable to prevent loosening and falling off.

[0023] Furthermore, the plug-in mechanism 4 includes a plug-in port 401 fixedly mounted on the inner surface of the sink 3, and movable plates 402 are rotatably provided at the upper and lower left ends of the inner surface of the plug-in port 401, and a rubber sleeve 403 is fixedly provided on the surface of the movable plate 402, and the height of the movable plate 402 exceeds half of the opening of the plug-in port 401.

[0024] By adopting the above technical solution, the rubber sleeve 403 contacts the wire 6 first, avoiding scratches and damage to the wire 6, and also increasing the friction force of the movable plate 402 pushing and clamping, so that the wire 6 can effectively drive the movable plate 402 to flip to the left when being pulled, thereby increasing the clamping force;

[0025] The movable plate 402 is set obliquely to the right, which also forms a certain obstruction for the terminal crystal plug 5. When the wire 6 is pulled to pull the terminal crystal plug 5, the terminal crystal plug 5 will also push the movable plate 402 from the right to the left, providing a more stable rotation force for the movable plate 402, making the clamping stronger.

[0026] Furthermore, the plug-in mechanism 4 also includes inclined grooves 404 formed at both the upper and lower ends of the inner surface of the plug-in port 401 , a spring 405 is fixedly mounted on the inner surface inclined surface of the inclined groove 404 , and one end of the spring 405 away from the inclined groove 404 is fixedly connected to the rubber sleeve 403 .

[0027] By adopting the above technical solution, the spring 405 provides the movable plate 402 with a force to rotate toward the middle, so that the movable plate 402 can stably fit and clamp the surface of the wire 6.

[0028] Furthermore, the locking mechanism 41 includes a fixing seat 411 fixedly installed on the front and rear sides of the outer surface of the plug-in port 401 , and a limiting rod 412 is rotatably provided in the middle of the surface of the fixing seat 411 .

[0029] By adopting the above technical solution, the limiting rod 412 can be rotated and adjusted according to the axial position of the fixing seat 411 .

[0030] Furthermore, the locking mechanism 41 further includes a spring piece 413 fixedly installed on the left side of the surface of the fixing seat 411 , and one end of the spring piece 413 is fixedly connected to the limiting rod 412 .

[0031] By adopting the above technical solution, the spring piece 413 gives the limiting rod 412 a thrust to always keep rotating toward the middle of the plug interface 401 .

[0032] Furthermore, the locking mechanism 41 also includes a through cavity 414 opened on the surface of the plug interface 401 and located on the right side of the fixing seat 411, and the shape of the limiting rod 412 is set to be "L"-shaped, and the short rod portion of the "L" shape passes through the through cavity 414 and is set to be an inclined surface. The overall volume of the terminal crystal head 5 is smaller than the opening size of the plug interface 401, and one end of the inclined surface of the limiting rod 412 matches the size of the card slot 7.

[0033] By adopting the above technical solution, the terminal crystal plug 5 can use the inclined surface to push the limit rod 412 to rotate and converge into the through cavity 414, so that the terminal crystal plug 5 can be normally inserted and connected;

[0034] When the right end of the limiting rod 412 is flush with the card slot 7 , the limiting rod 412 is pushed into the card slot 7 by the action of the spring sheet 413 , so as to lock and position the terminal plug 5 .

[0035] Working principle: When using the installation structure of the electronic throttle pedal electrical parameter acquisition device, first, when using the acquisition device body 1 to collect parameters of the electronic throttle pedal, insert the transmission wire 6 and the terminal crystal head 5 of the electronic throttle pedal into the plug interface 401, and the terminal crystal head 5 pushes the movable plate 402 to rotate to the right and squeezes the spring 405. After the terminal crystal head 5 is fully inserted, the spring 405 pushes the movable plate 402 to rotate toward the middle, and preferentially contacts the wire 6 through the rubber sleeve 403 to fit tightly and clamp the wire 6. When the terminal crystal head 5 and the wire 6 are pulled and moved by external force, the friction force of the rubber sleeve 403 will also drive the movable plate 402 to rotate outward, but the wire 6 itself occupies a certain space volume in the middle of the plug interface 401, which makes the movable plate 402 unable to rotate completely to the left. As it is pulled continuously, the squeezing force of the movable plate 402 toward the middle will only increase, clamping the wire 6 The movable plate 402 is more tightly packed, and the movable plate 402 is tilted to the right. The volume of the terminal crystal head 5 also makes it impossible to push the movable plate 402 to rotate and open the plug interface 401, that is, the terminal crystal head 5 and the wire 6 can be installed and connected with the acquisition device body 1 extremely stably. At the same time, when the terminal crystal head 5 is inserted into the plug interface 401, the inclined surface is used to push the limit rod 412 to rotate along the fixing seat 411, converge into the through cavity 414, and squeeze the spring piece 413. When the right end of the limit rod 412 is flush with the card slot 7, under the action of the spring piece 413, the limit rod 412 will be pushed to insert into the card slot 7. At this time, the terminal crystal head 5 can be connected to the terminal of the electrical device inside the acquisition device body 1 and fixed. After the wire 6 is connected, the power switch 2 is turned on, and the acquisition device body 1 is started to collect the working data parameters of the electronic throttle pedal. This is the working principle of the installation structure of the electronic throttle pedal electrical parameter acquisition device.
