一种基于抽拉杆架构的便携式发电机组Portable generator set based on drawbar structure

技术领域Technical field

本发明涉及便携式发电机组技术领域，具体涉及一种基于抽拉杆架构的便携式逆变发电机组。The invention relates to the technical field of portable generator sets, and in particular to a portable inverter generator set based on a drawbar structure.

背景技术Background technique

发电机组主要由发动机、发电机和电控***构成，能将燃油的化学能转化为电能，具有广泛的应用，例如：野外作业、应急用电、灾害救治、户外生活及旅行、游艇及车辆自备电源、移动通讯基站等诸多场合。The generator set is mainly composed of an engine, a generator and an electronic control system. It can convert the chemical energy of fuel into electric energy and has a wide range of applications, such as: field operations, emergency power, disaster treatment, outdoor life and travel, yachts and vehicles. Standby power supply, mobile communication base station and many other occasions.

与传统的工频同步发电机组相比，采用多极永磁发电机的逆变发电机组具有效率高、体积小、重量轻的优点，其重量和体积只有传统机组的50％左右，是真正可实现“便携”的发电机组。Compared with the traditional power frequency synchronous generator set, the inverter generator set with multi-pole permanent magnet generator has the advantages of high efficiency, small size and light weight. Its weight and volume are only about 50% of the traditional unit, which is truly Achieve "portable" generator sets.

但是，2kw左右的逆变发电机组重量一般也都在20kg以上，搬运和携带还是很不方便。如图1a、图1b和图2所示，现有技术的解决方案是：在发电机组2前侧设置转动式拉杆202，转动式拉杆202一端与发电机组前侧顶部通过转轴2022连接，另一端设置手柄2021，转动式拉杆202可以绕转轴2022上、下翻转；在发电机组2后侧底部沿着发电机组横向布置滚轮201，即滚轮201的轴线与发电机组宽度W方向一致。当需要搬运发电机组2时，可以将转动式拉杆202向上翻转到最高位置，握住手柄2021抬起发电机组前部，向后倾斜发电机组，然后就可以向前拖动发电机组2。但是这种设计存在很多问题，如图2所示，当操作者抬起发电机组前部向前拖动发电机组2时，由于发电机组2是向后(与前进方向相反)倾斜的，发电机组前部下方P区域203距离操作者的脚和腿很近，很容易磕碰到操作者，严重时可能会导致受伤，这给操作者快速拖动发电机组造成很大障碍。而且，转动式拉杆202打开和收回过程动作比较复杂，操作不太方便，效率较低。另一方面，在拖动发电机组2过程中，操作者必须始终用向上的力F去克服发电机组的重量G才能抬起发电机组前部，由于发电机组2的长度L较大(大于宽度W)，发电机组2的重心与滚轮 201中心在水平方向的距离B较大，当手柄2021与滚轮201中心在水平方向的距离A+B一定时，由于F＝G＊B/(A+B)，故F较大，操作者搬运发电机组2还是很费力。此外，现有发电机组2的两个滚轮201共用一根轮轴，贯穿整个发电机组2的轮轴浪费了机壳内部的空间，只能采用直径较小的滚轮，小直径滚轮与地面的滚轮阻力较大，路况的适应能力较差，且搬运时发电机组的通过能力也较差。However, the weight of the inverter generator set of about 2kw is generally more than 20kg, and it is very inconvenient to carry and carry. As shown in FIG. 1a, FIG. 1b and FIG. 2, the prior art solution is: a rotary pull rod 202 is arranged on the front side of the generator set 2, and one end of the rotary pull rod 202 is connected with the top of the front side of the generator set through the rotating shaft 2022, and the other end is connected. The handle 2021 is provided, and the rotary pull rod 202 can be turned upside down about the rotating shaft 2022; the roller 201 is arranged laterally along the generator set at the bottom of the rear side of the generator set 2, that is, the axis of the roller 201 is aligned with the width W of the generator set. When the generator set 2 needs to be transported, the rotary pull rod 202 can be turned up to the highest position, the handle 2021 is held up to lift the front of the generator set, the generator set is tilted backward, and then the generator set 2 can be dragged forward. However, there are many problems with this design. As shown in Fig. 2, when the operator lifts the front of the generator set and drags the generator set 2 forward, since the generator set 2 is tilted backward (opposite to the forward direction), the generator set The front lower P area 203 is close to the operator's feet and legs, and it is easy to bump into the operator. In severe cases, it may cause injury, which causes a great obstacle for the operator to quickly drag the generator set. Moreover, the opening and retracting process of the rotary lever 202 is relatively complicated, the operation is not convenient, and the efficiency is low. On the other hand, in the process of dragging the genset 2, the operator must always use the upward force F to overcome the weight G of the genset to lift the front of the genset, since the length L of the genset 2 is larger (greater than the width W) ), the center of gravity of the generator set 2 and the wheel The distance B of the center of the 201 is large in the horizontal direction. When the distance A+B between the handle 2021 and the center of the roller 201 in the horizontal direction is constant, since F=G*B/(A+B), F is large, and the operator carries Generator set 2 is still very laborious. In addition, the two rollers 201 of the existing generator set 2 share one axle, and the axle of the entire generator set 2 wastes the space inside the casing, and only the roller with a smaller diameter can be used, and the resistance of the roller of the small diameter roller and the ground is higher. Large, the road conditions have poor adaptability, and the ability of the generator set to pass is also poor.

本发明的便携式发电机组正是着眼于现有发电机组的不足，为发电机组设计了更合理的拉杆装置，以发电机组和拉杆装置为基本架构对发电机组上的部件结构和位置进行一系列的调整优化设计。使其在被移动时更省力，不会磕碰到操作者，确保操作者可以快速、安全地向前拖动发电机组，并且更合理的利用发电机组空间，改进了操作界面，使其便携性和操作便利性大大提高。The portable generator set of the invention focuses on the deficiencies of the existing generator set, and designs a more reasonable pull rod device for the generator set.

It makes it more labor-saving when it is moved, does not hit the operator, ensures that the operator can quickly and safely drag the generator set forward, and more rational use of the generator set space, improve the operation interface, make it portable and The convenience of operation is greatly improved.

图4是发电机组1搬运受力分析，由于搬运时发电机组1的倾斜方向与其前进方向一致，发电机组1下方S区域106距离操作者的脚和腿较远，不会磕碰到操作者，因此操作者可以快速、安全地向前拖动发电机组。另一方面，由于本实施例将滚轮301的轴线设置成与发电机组的长度L方向一致，相对于发电机组1的长度L，由于发电机组1的宽度W较小，当向发电机组右侧面104倾斜以拖运发电机组1时，发电机组1的重心基本上处于滚轮301中心的正上方，即滚轮301中心与发电机组1重心在水平方向上的距离B很小，当拉杆装置4的手柄403与滚轮301中心在水平方向的距离A+B一定时，由于F＝G＊B/(A+B)，故力F很小，操作会非常省力，即在拖动发电机组1过程中，操作者只需用很小的力F就能克服发电机组1的重量G使发电机组左侧面103离开地面，操作者搬运发电机组1时会非常轻松，大大提高了发电机组的便携性。4 is a load analysis of the genset 1 . Since the tilt direction of the genset 1 coincides with its advancing direction during transport, the S region 106 below the genset 1 is far from the operator's feet and legs and does not hit the operator. The operator can drag the generator set forwards quickly and safely. On the other hand, since the axis of the roller 301 is arranged to coincide with the length L direction of the genset according to the embodiment, with respect to the length L of the genset 1, since the width W of the genset 1 is small, when facing the right side of the genset When tilting 104 to haul the generator set 1, the center of gravity of the genset 1 is substantially directly above the center of the roller 301, that is, the distance B between the center of the roller 301 and the center of gravity of the genset 1 in the horizontal direction is small, when the handle of the pull rod device 4 is When the distance 403 from the center of the roller 301 in the horizontal direction is constant, since F=G*B/(A+B), the force F is small, and the operation is very labor-saving, that is, during the process of dragging the generator set 1, The operator can overcome the weight G of the generator set 1 with a small force F to make the left side 103 of the generator set off the ground, and the operator can easily move the generator set 1 and greatly improve the portability of the generator set.

当拉杆装置4的拉杆401全部缩回到位时，在锁定装置1上的锁定弹簧4073驱动下，锁定装置1上的锁头4072***第二节拉杆4012下端的开孔，从而使第一节和第二节拉杆之间被锁定；在锁定装置1底部的触头4084挤压下，锁定装置2上的锁头4082克服其锁定弹簧4083***第三节拉杆4013下端的开孔，从而使第二节和第三节拉杆之间被锁定；在锁定装置2底部的触头4094挤压下，锁定装置3上的锁头4092克服其锁定弹簧4093***杆筒402下端的开孔，从而使第三节拉杆4013和杆筒402之间被锁定，从而整个拉杆装置4都处于“缩回锁定状态”，如图5所示。When the pull rod 401 of the pull rod device 4 is fully retracted, the lock head 4072 on the locking device 1 is inserted into the opening of the lower end of the second link rod 4012 under the driving of the locking spring 4073 on the locking device 1, thereby making the first section and the first section The second section of the tie rod is locked; when the contact 4084 at the bottom of the locking device 1 is pressed, the lock head 4082 on the locking device 2 is inserted into the opening of the lower end of the third section tie rod 4013 against the locking spring 4083 thereof, thereby making the second The locking between the section and the third section of the lever is locked; when the contact 4094 at the bottom of the locking device 2 is pressed, the locking head 4092 on the locking device 3 is inserted into the opening of the lower end of the barrel 402 against the locking spring 4093 thereof, thereby making the third The tie rod 4013 and the barrel 402 are locked so that the entire rod unit 4 is in the "retracted locked state" as shown in FIG.

要从上述拉杆装置4的“缩回锁定状态”打开使用拉杆401，必须按压手柄403上的解锁按钮404，解锁按钮404的下部与手柄403之间设置有解锁弹簧406，解锁按钮的左右两端各与一个导杆405连接，导杆405处于第一节拉杆4011内，长度与第一节拉杆4011接近，导杆405的下端与锁定装置1上部的触头4074连接。当克服解锁弹簧406按下手柄403上的解锁按钮404时，导杆405的上端被解锁按钮404同时下压，带动导杆405的下端推动锁定装置1上部的触头4074，该触头4074上的斜面开始挤压锁定装置1上的锁头斜面，锁头4072克服其锁定弹簧4073退回锁定装置1内，第一节与第二节拉杆之间被解锁。被解锁后的第一节拉杆4011可以从第二节拉杆4012中向上抽出，直至锁头4072在其锁定弹簧4073驱动下***第二节拉杆4012上端的开孔中，第一节与第二节拉杆进入“打开锁定状态”。此时，第一节拉杆4011底部的触头4084已不再挤压锁定装置2上的锁头斜面，在其锁定弹簧4083的驱动下，锁头4082退回锁定装置2内，第二节与第三节拉杆之间被解锁。被解锁后的第二节拉杆4012可以从第三节拉杆4013中向上抽出，直至锁头4082在其锁定弹簧4083驱动下***第三节拉杆4013上端的开孔中，第二节与第三节拉杆进入“打开锁定状态”。此时，第二节拉杆4012底部的触头4094已不再挤压锁定装置3上的锁头斜面，在其锁定弹簧4093的驱动下，锁头4092退回锁定装置3内，第三节拉杆4013与杆筒402之间被解锁。被解锁后的第三节拉杆4013可以从杆筒402中向上抽出，直至锁头4092在其锁定弹簧4093驱动下***杆筒402上端的开孔中，第三节拉杆4013与杆筒402进入“打开锁定状态”，从而整个拉杆装置4都处于“打开锁定状态”，如图6所示。To open the use lever 401 from the "retracted locked state" of the above-described lever device 4, the unlock button 404 on the handle 403 must be pressed, and an unlocking spring 406 is disposed between the lower portion of the unlock button 404 and the handle 403, and the left and right ends of the unlocking button are Each of them is connected to a guide rod 405 which is in the first section of the tie rod 4011 and has a length close to the first section of the rod 4011. The lower end of the guide rod 405 is connected to the contact 4074 of the upper portion of the locking device 1. When the unlocking button 404 of the handle 403 is pressed against the unlocking spring 406, the upper end of the guiding rod 405 is simultaneously depressed by the unlocking button 404, and the lower end of the guiding rod 405 is pushed to push the contact 4074 of the upper portion of the locking device 1, the contact 4074 The bevel starts to press the lock bevel on the locking device 1, and the lock 4072 is retracted into the locking device 1 against the locking spring 4073, between the first and second links. Was unlocked. The unlocked first section lever 4011 can be pulled upward from the second section lever 4012 until the lock head 4072 is driven by the locking spring 4073 to be inserted into the opening of the upper end of the second section lever 4012, the first section and the second section. The lever enters the "open lock state". At this time, the contact 4084 at the bottom of the first link rod 4011 no longer presses the lock bevel on the locking device 2, and under the driving of the locking spring 4083, the lock 4082 is retracted into the locking device 2, the second section and the second The three-section tie rods are unlocked. The unlocked second section lever 4012 can be pulled upward from the third section lever 4013 until the lock head 4082 is driven by the locking spring 4083 to be inserted into the opening of the upper end of the third section lever 4013, the second section and the third section. The lever enters the "open lock state". At this time, the contact 4094 at the bottom of the second link 4012 no longer presses the lock bevel on the locking device 3, and under the driving of the locking spring 4093, the lock 4092 is retracted into the locking device 3, and the third link 4013 It is unlocked from the barrel 402. The unlocked third section lever 4013 can be pulled upward from the barrel 402 until the lock head 4092 is inserted into the opening of the upper end of the barrel 402 under the driving of its locking spring 4093, and the third section rod 4013 and the barrel 402 enters " The locked state is opened so that the entire lever device 4 is in the "open locked state" as shown in FIG.

要从上述拉杆装置4的“打开锁定状态”收回拉杆401，也必须按压手柄403上的解锁按钮404后下压手柄403，在导杆405和相应触头的推动下，锁定装置1、锁定装置2和锁定装置3逐级解锁相应拉杆，持续下压手柄403就能使所有拉杆401全部缩回杆筒402内。To retract the pull rod 401 from the "open lock state" of the above-mentioned pull rod device 4, it is also necessary to press the unlock button 404 on the handle 403 and then press the handle 403, under the push of the guide rod 405 and the corresponding contact, the locking device 1, the locking device 2 and the locking device 3 unlocks the corresponding levers step by step, and continuously pressing the handle 403 can completely retract all the rods 401 into the barrel 402.

由上述抽拉式拉杆装置4的结构和工作过程可以看出，与传统的转动式拉杆202相比，由于本发明的拉杆装置4采用了多节拉杆嵌套伸缩结构，很容易将拉杆装置4打开时的长度做的更长，即相同条件下，抽拉式拉杆装置4的手柄403与滚轮301中心在水平方向的距离A+B较大，由于F＝G＊B/(A+B)，故力F进一步减小，相同条件下操作会更加省力。另一方面，抽拉式拉杆装置4能够快速打开和缩回，操作极为方便，效率很高。而且拉杆401全部缩回杆筒402后不占空间，使便携式发电机组结构更加紧凑。It can be seen from the structure and working process of the above-mentioned pull-type drawbar device 4 that, compared with the conventional rotary tie rod 202, since the drawbar device 4 of the present invention adopts a multi-section tie rod nesting telescopic structure, it is easy to pull the rod device 4 The length when opening is made longer, that is, under the same conditions, the distance A+B between the handle 403 of the pull-type drawbar device 4 and the center of the roller 301 in the horizontal direction is larger, since F=G*B/(A+B) Therefore, the force F is further reduced, and the operation under the same conditions is more labor-saving. On the other hand, the pull-type drawbar device 4 can be quickly opened and retracted, and the operation is extremely convenient and efficient. Moreover, the tie rods 401 are all retracted into the barrel 402 and do not occupy space, so that the portable generator set structure is more compact.

如图7a至图19所示，在发电机组前侧面101和后侧102各设置有一个滚轮装置3，滚轮装置3靠近发电机组右侧面104设置，本实施例滚轮装置3与下机壳503相连。滚轮装置3主要由滚轮301、支架302、卡扣结构3021、螺钉柱3022、轮轴303、挡圈304和螺母305构成。两个滚轮装置3内部都有自己独立的轮轴303，两个滚轮装置3之间无轮轴连接。滚轮装置3的滚轮301处于其支架302内，支架302的两侧分别与其轮轴303两端相连，轮轴303穿过其支架302和滚轮301将它们连接在一起，轮轴303的两端各设置有一个挡圈304以限位，挡圈304处于其支架302外侧的凹坑内。支架302设置在下机壳503底部的内凹结构5031中，支架302通过其卡扣结构3021与下机壳503底部的卡槽5032相连。支架302顶部设置有螺钉柱3022，螺钉柱3022从下往上穿过下机壳503底部开孔，开孔上方的螺母305与螺钉柱3022相连，将支架302与下机壳503连接到一起。As shown in FIG. 7a to FIG. 19, a roller device 3 is disposed on each of the front side 101 and the rear side 102 of the genset. The roller device 3 is disposed adjacent to the right side surface 104 of the genset. The roller device 3 and the lower casing 503 of this embodiment are provided. Connected. The roller device 3 is mainly composed of a roller 301, a bracket 302, a snap structure 3021, a screw post 3022, an axle 303, a retaining ring 304 and a nut 305. Both roller devices 3 have their own internal The independent axle 303 has no axle connection between the two roller devices 3. The roller 301 of the roller device 3 is in its bracket 302. Both sides of the bracket 302 are respectively connected to both ends of the axle 303 thereof. The axle 303 connects them through the bracket 302 and the roller 301, and one end of each of the axles 303 is provided. The retaining ring 304 is in a limit position and the retaining ring 304 is in a recess outside the bracket 302. The bracket 302 is disposed in the recessed structure 5031 at the bottom of the lower casing 503, and the bracket 302 is connected to the slot 5032 at the bottom of the lower casing 503 through the buckle structure 3021. The top of the bracket 302 is provided with a screw post 3022. The screw post 3022 is opened through the bottom of the lower casing 503 from bottom to top. The nut 305 above the opening is connected with the screw post 3022 to connect the bracket 302 and the lower casing 503 together.

现有发电机组2的两个滚轮201共用一根轮轴，该轮轴两端与两个滚轮201相连，中间部分贯穿整个机壳，占据机壳内部的轮轴会浪费较大空间，这也限制了滚轮直径不能做大，而小直径滚轮与地面的滚动阻力较大，因此发电机组搬运时的行进阻力较大，滚轮对路况的适应能力较差，而且由于轮轴距离地面较近，搬运时发电机组的通过能力也较差。而本发明每个滚轮301都有自己独立的轮轴303，每个轮轴303两端由其支架302支撑，两个轮轴303之间无需连接在一起，因此机壳5内部无轮轴，不会浪费机壳内部空间，故允许采用直径更大的滚轮，大大提高了滚轮对各种路况的适应能力，减小了发电机组搬运时滚轮的行进阻力，同时大直径滚轮也提高了通过能力。The two rollers 201 of the existing generator set 2 share one axle, the two ends of the axle are connected with two rollers 201, and the middle portion penetrates the entire casing, and the axle occupying the inside of the casing wastes a large space, which also limits the roller. The diameter cannot be made large, and the rolling resistance of the small-diameter roller and the ground is large. Therefore, the traveling resistance of the generator set is large, the adaptability of the roller to the road condition is poor, and since the axle is closer to the ground, the generator set is moved. Passing ability is also poor. Each of the rollers 301 of the present invention has its own independent axle 303. Each of the axles 303 is supported by its bracket 302. The two axles 303 need not be connected together, so there is no axle inside the casing 5, and no machine is wasted. The inner space of the shell allows the use of larger diameter rollers, which greatly improves the adaptability of the roller to various road conditions, reduces the resistance of the roller when the generator set is moved, and the large diameter roller also improves the passing ability.

靠近发动机6上部设置有燃油油箱8，发电机组1顶部设置有外露的油箱口801和油箱盖802，油箱口801和油箱盖802设置在拉杆装置4的不同侧，如图8至图19所示，本实施例拉杆装置4设置在发电机组右侧面104，因此油箱口801和油箱盖802被设置在发电机组左侧面103的左机壳501上。为了避免向油箱口801加注燃油时，飞溅出来的燃油污染拉杆装置4，油箱口801和油箱盖802的位置应尽可能远离拉杆装置4的手柄403，因此本实施例中的油箱口801和油箱盖802被设置在左机壳501的最外侧。如图14所示，油箱口801的颈部还设置有橡胶密封盘803，橡胶密封盘803周边设置有突起的边缘，防止飞溅出来的燃油流入机壳5内，橡胶密封盘803突起的边缘外侧设置有燃油流出缺口，防止进入橡胶密封盘803中的燃油溢出时不受约束地四处流淌。 A fuel oil tank 8 is disposed near the upper portion of the engine 6. The top of the generator set 1 is provided with an exposed fuel tank port 801 and a fuel tank cap 802. The fuel tank port 801 and the fuel tank cap 802 are disposed on different sides of the rod device 4, as shown in FIGS. 8 to 19.
